技术领域 technical field
本发明涉及无线通信技术，尤其涉及一种高铁通信网络中用户迁移的方法及装置。The invention relates to wireless communication technology, in particular to a method and device for user migration in a high-speed rail communication network.
背景技术 Background technique
为了适应高速铁路(以下简称高铁)的运行环境，保证高铁用户的通信质量，高铁通信网络中的信号强度较高，通常会强于公共通信网络(以下简称公网)。基于此，一些接近高铁通信网络的公网用户(通常是指行人或公共汽车等上的车载用户)会被吸纳到高铁通信网络，公网用户通常为低速用户。另外，由于列车运行特性(例如进站、出站、紧急刹车等)也会形成低速用户。In order to adapt to the operating environment of high-speed rail (hereinafter referred to as high-speed rail) and ensure the communication quality of high-speed rail users, the signal strength in the high-speed rail communication network is relatively high, usually stronger than that of the public communication network (hereinafter referred to as the public network). Based on this, some public network users (usually pedestrians or vehicle users on buses) close to the high-speed rail communication network will be absorbed into the high-speed rail communication network, and public network users are usually low-speed users. In addition, low-speed users will also be formed due to the characteristics of train operation (such as entering, exiting, emergency braking, etc.).
高铁通信网络中低速用户对高铁通信网络资源的消耗，会减少分配给高速用户的资源，将影响高速用户的通信质量，例如：影响高速用户的接入、切换等以至于造成高速用户掉话。对低速用户来说，公网通常可以满足其通信需求，因此，可以通过将高铁通信网络中的低速用户迁移至相邻的公网小区，以降低低速用户对高铁通信网络资源的消耗。The consumption of resources by low-speed users in the high-speed rail communication network will reduce the resources allocated to high-speed users, which will affect the communication quality of high-speed users, for example, affecting the access and switching of high-speed users and causing high-speed users to drop calls. For low-speed users, the public network can usually meet their communication needs. Therefore, low-speed users in the high-speed rail communication network can be migrated to adjacent public network cells to reduce the consumption of low-speed users on high-speed rail communication network resources.
但是，由于低速用户的成因不同，如果盲目将所有低速用户都迁出有可能使因列车运行特性形成的低速用户在列车重新提速时重新成为高速用户而发生掉话，无法正常通信。因此，如何将低速公网用户迁出高铁通信网络而又不影响用户的通信成为高铁通信有待解决的问题。However, due to the different causes of low-speed users, if all low-speed users are moved out blindly, the low-speed users formed due to the characteristics of the train may become high-speed users again when the train speeds up again, resulting in call drop and normal communication. Therefore, how to relocate low-speed public network users out of the high-speed rail communication network without affecting the user's communication has become a problem to be solved by high-speed rail communication.

具体实施方式 Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
图1为本发明实施例一提供的高铁通信网络中用户迁移的方法流程图。如图1所示，本实施例的方法包括：FIG. 1 is a flowchart of a method for user migration in a high-speed rail communication network provided by Embodiment 1 of the present invention. As shown in Figure 1, the method of the present embodiment includes:
步骤101、根据基站在速度判决周期内上报的多个速度值和至少一个预设速度门限值，获取用户终端的速度状态；Step 101. Obtain the speed status of the user terminal according to multiple speed values reported by the base station within the speed judgment period and at least one preset speed threshold value;
在高铁通信网络中，网络侧的无线网络控制器(Radio Network Controller；简称为：RNC)会根据高速铁路的线路将高铁通信网络划分为不同的高铁通信小区，例如站台小区、沿线小区等。每个高铁通信小区与公网通信小区相类似，均被基站覆盖，即高铁通信小区内的用户通过基站与RNC进行通信。其中，基站会周期性的向RNC上报基站下各个用户终端的速度值。对于每个用户终端，基站可以根据接收到的信号强度计算该用户终端的运动速度，其中，频偏估计是一种较为常用的获取用户终端速度的方式，但并不限于此。In the high-speed rail communication network, the radio network controller (Radio Network Controller; RNC for short) on the network side will divide the high-speed rail communication network into different high-speed rail communication cells according to the high-speed rail lines, such as platform cells and along-line cells. Each high-speed rail communication cell is similar to the public network communication cell and is covered by a base station, that is, users in the high-speed rail communication cell communicate with the RNC through the base station. Wherein, the base station will periodically report the speed value of each user terminal under the base station to the RNC. For each user terminal, the base station can calculate the moving speed of the user terminal according to the received signal strength, wherein frequency offset estimation is a relatively common way to obtain the speed of the user terminal, but it is not limited thereto.
在网络侧，RNC可以预先定义一个或多个速度门限值。当高铁通信小区中存在用户时，RNC会根据预设的速度门限值，将用户终端的速度划分为不同的级别，以识别用户终端的速度状态，例如识别用户终端为低速、高速还是中速等。在本实施例以多个速度门限值为例，这样可以将用户的速度状态划分的更细。例如：当用户终端的速度低于一定速度门限值为低速，高于另一速度门限值为高速，介于两个速度门限值之间时为中速。On the network side, the RNC can predefine one or more speed thresholds. When there are users in the high-speed rail communication cell, the RNC will divide the speed of the user terminal into different levels according to the preset speed threshold to identify the speed status of the user terminal, such as identifying whether the user terminal is low speed, high speed or medium speed wait. In this embodiment, multiple speed thresholds are taken as an example, so that the user's speed status can be divided more finely. For example, when the speed of the user terminal is lower than a certain speed threshold, it is low speed, when it is higher than another speed threshold, it is high speed, and when it is between the two speed thresholds, it is medium speed.
步骤102、根据用户终端的速度状态，获取用户终端的移动状态；Step 102, according to the speed state of the user terminal, obtain the mobile state of the user terminal;
其中，根据用户终端是低速还是高速以及中速等，确定用户的移动状态。在本实施例中，用户终端的移动状态可用于表征用户终端的运动趋势，以便于对用户终端进行正确迁移。Wherein, according to whether the user terminal is at low speed, high speed, medium speed, etc., the mobile state of the user is determined. In this embodiment, the moving state of the user terminal may be used to characterize the movement trend of the user terminal, so as to facilitate correct migration of the user terminal.
步骤103、根据用户终端的移动状态和用户终端所在高铁通信小区的特性信息，向用户终端发送测量控制消息，以使用户终端对指定相邻通信小区进行1G/2A事件测量和/或进行邻区周期测量并上报测量结果；Step 103, according to the mobile state of the user terminal and the characteristic information of the high-speed rail communication cell where the user terminal is located, send a measurement control message to the user terminal, so that the user terminal performs 1G/2A event measurement and/or conducts adjacent cell for the designated adjacent communication cell Periodic measurement and reporting of measurement results;
RNC根据用户终端的移动状态和所在高铁通信小区的特性信息，通过向用户终端发送测量控制消息，来配置用户终端的测量策略，使用户终端根据测量控制消息对指定相邻通信小区的信号强度进行测量并上报测量结果，以使RNC根据用户终端上报的测量结果确定用户终端的目标通信小区。其中，用户终端所在高铁通信小区的特性信息主要是指高铁通信小区的类型，例如是站台小区还是沿线小区等，且RNC可以直接根据配置策略获取该特性信息。According to the mobile state of the user terminal and the characteristic information of the high-speed rail communication cell where it is located, the RNC configures the measurement strategy of the user terminal by sending a measurement control message to the user terminal, so that the user terminal can measure the signal strength of the designated adjacent communication cell according to the measurement control message Measuring and reporting the measurement results, so that the RNC determines the target communication cell of the user terminal according to the measurement results reported by the user terminal. Wherein, the characteristic information of the high-speed rail communication cell where the user terminal is located mainly refers to the type of the high-speed rail communication cell, such as a station cell or a cell along the line, etc., and the RNC can directly obtain the characteristic information according to the configuration policy.
步骤104、根据用户终端上报的测量结果，将用户终端迁移至目标通信小区。Step 104: Migrate the user terminal to the target communication cell according to the measurement result reported by the user terminal.
RNC根据用户终端上报的测量结果，在确定用户终端的目标通信小区(即下一个通信小区)后，将用户终端迁移至该目标通信小区。After the RNC determines the target communication cell (ie, the next communication cell) of the user terminal according to the measurement result reported by the user terminal, the RNC migrates the user terminal to the target communication cell.
其中，如果用户终端为低速用户且为被吸纳如高铁通信网络中的公网用户，则RNC所确定的目标通信小区为公网小区，通过迁移操作可以将该公网用户终端迁出高铁专网小区；如果用户终端为高铁通信网络中的低速或高速用户或者RNC无法确定用户终端是公网用户还是高铁通信网络的用户，则RNC可以根据该用户终端的实际移动方向或状态确定该用户终端的目标通信小区，通过将用户终端迁移至目标通信小区可以保证该用户终端正常通信，而不掉话。Among them, if the user terminal is a low-speed user and is a public network user absorbed in the high-speed rail communication network, the target communication cell determined by the RNC is a public network cell, and the public network user terminal can be moved out of the high-speed rail private network through the migration operation Cell; if the user terminal is a low-speed or high-speed user in the high-speed rail communication network or the RNC cannot determine whether the user terminal is a user of the public network or a user of the high-speed rail communication network, the RNC can determine the location of the user terminal according to the actual moving direction or state of the user terminal The target communication cell, by migrating the user terminal to the target communication cell, can ensure that the user terminal communicates normally without dropping calls.
本实施例的高铁通信网络中用户迁移的方法，根据用户终端的速度值获取运动状态，根据运动状态获取用户终端的移动状态，然后根据用户终端的移动状态和所在高铁通信小区的类型向用户终端发送测量控制消息以给用户终端配置不同的测量策略，并接收用户终端根据不同测量策略上报的测量结果，根据相应测量结果确定该用户终端对应的目标通信小区并对该用户终端进行迁移，因此，可以在保证各用户终端正常通信的基础上，将低速用户迁出高铁通信网络，降低低速用户对高铁通信网络中资源的消耗，提高对高速用户的服务质量。In the method for user migration in the high-speed rail communication network of this embodiment, the motion state is obtained according to the speed value of the user terminal, the motion state of the user terminal is obtained according to the motion state, and then the user terminal is sent to the user terminal according to the motion state of the user terminal and the type of the high-speed rail communication cell where the user terminal is located. Sending a measurement control message to configure different measurement strategies for the user terminal, and receiving the measurement results reported by the user terminal according to different measurement strategies, determining the target communication cell corresponding to the user terminal according to the corresponding measurement results, and relocating the user terminal, therefore, On the basis of ensuring the normal communication of each user terminal, low-speed users can be moved out of the high-speed rail communication network, reducing the consumption of resources in the high-speed rail communication network by low-speed users, and improving the service quality for high-speed users.
在本实施例步骤101中，RNC所设定的至少一个速度门限值包括低速门限值、中速门限值和高速门限值，但并不限于此。其中，所设定的低速门限值要求能够明确识别出步行类用户，例如根据实际场景可以设置为20～30Km/h(千米/小时)，通常步行类或进入站台区域的车辆均不会超出该速度。所设定的中速门限值要求能够明确区分正常运行的车载用户与低速用户和高速铁路上运行的列车，例如根据实际场景可以设置为120～150Km/h，通常高速公路上的车辆速度为80～100Km/h，最高也不会超过150Km/h，因此，上述中速门限值的范围足以区分所有高速上的车辆。所设定的高速门限值要求能够区分出高速铁路上运行的列车，例如根基实际场景可以设置为250～300Km/h，目前高速铁路上列车的运行速度均在上述范围之内。本实施例所设定的速度门限值主要是结合目前各种车辆和行人的实际运行速度来设定的，其中对于高速门限值也可以不做限定，只要高于中速门限值的均可以设定为高速。In step 101 of this embodiment, the at least one speed threshold set by the RNC includes a low speed threshold, a medium speed threshold and a high speed threshold, but is not limited thereto. Among them, the set low-speed threshold needs to be able to clearly identify pedestrian users. For example, it can be set to 20-30Km/h (kilometers per hour) according to the actual scene. Usually, pedestrians or vehicles entering the platform area will not exceed this speed. The set medium-speed threshold needs to be able to clearly distinguish normal running vehicle users from low-speed users and trains running on high-speed railways. For example, it can be set to 120-150Km/h according to actual scenarios. Usually, the speed of vehicles on expressways is 80 ~ 100Km/h, the highest will not exceed 150Km/h, therefore, the range of the above medium speed threshold is enough to distinguish all high-speed vehicles. The set high-speed threshold needs to be able to distinguish trains running on high-speed railways. For example, the basic actual scenario can be set to 250-300Km/h. Currently, the running speed of trains on high-speed railways is within the above range. The speed threshold value set in this embodiment is mainly set in conjunction with the actual running speeds of various vehicles and pedestrians at present, and there is no limit to the high speed threshold value, as long as it is higher than the medium speed threshold value Both can be set to high speed.
另外，为了提高对用户终端速度状态判断的准确性，RNC预先设定速度判决周期，该速度判决周期为秒级，并设定包括基站的多个速度上报周期，以获取该用户终端的多个速度值。In addition, in order to improve the accuracy of judging the speed state of the user terminal, the RNC pre-sets the speed judging cycle, which is at the second level, and sets multiple speed reporting cycles including the base station, so as to obtain multiple speeds of the user terminal. speed value.
基于上述，本实施例步骤101获取用户终端的速度状态的过程为：RNC在速度判决周期内，接收基站上报的用户终端的多个速度值；然后，将速度判决周期内的每个速度值均与至少一个预设速度门限值进行比较，即将每个速度值分别与低速门限值和中速门限值进行比较。若速度判决周期内的多个速度值均小于或等于低速门限值，即用户速度使用低于低速门限值，确定速度判决周期内用户终端的速度状态为低速状态；若速度判决周期内的多个速度值均大于中速门限值，确定速度判决周期内用户终端的速度状态为高速状态，并标识该用户终端为高速用户；若速度判决周期内的多个速度值均大于低速门限值，且小于或等于中速门限值，且根据多个速度值的大小关系确定出用户终端的移动速度并非逐渐增大或逐渐减小，即维持在中速门限值以下，确定速度判决周期内用户终端的速度状态为稳定中速状态；若速度判决周期内的多个速度值均大于低速门限值，且小于或等于中速门限值，并且根据多个速度值的大小关系确定出用户终端的移动速度在逐渐增大或逐渐减小，确定速度判决周期内用户终端的速度状态为非稳定中速状态，并进入下一个速度判决周期以继续判断该用户终端的速度状态。Based on the above, the process of obtaining the speed state of the user terminal in step 101 of this embodiment is as follows: the RNC receives multiple speed values of the user terminal reported by the base station within the speed judgment period; Comparing with at least one preset speed threshold value, that is, comparing each speed value with a low speed threshold value and a medium speed threshold value respectively. If a plurality of speed values in the speed judgment period are all less than or equal to the low-speed threshold value, that is, the user speed is used lower than the low-speed threshold value, the speed state of the user terminal in the speed judgment period is determined to be a low-speed state; Multiple speed values are greater than the medium-speed threshold value, determine the speed state of the user terminal in the speed judgment period as a high-speed state, and identify the user terminal as a high-speed user; if multiple speed values in the speed judgment period are greater than the low-speed threshold value, and less than or equal to the medium-speed threshold value, and according to the size relationship of multiple speed values, it is determined that the moving speed of the user terminal is not gradually increasing or decreasing, that is, it is maintained below the medium-speed threshold value, and the speed judgment is determined The speed state of the user terminal within the cycle is a stable medium speed state; if multiple speed values in the speed judgment cycle are greater than the low speed threshold value and less than or equal to the medium speed threshold value, and determined according to the magnitude relationship of multiple speed values If the moving speed of the user terminal is gradually increasing or decreasing, it is determined that the speed state of the user terminal in the speed judgment cycle is an unstable medium speed state, and enters the next speed judgment cycle to continue judging the speed state of the user terminal.
基于上述，本实施例步骤102的一种实施方式包括：Based on the above, an implementation manner of step 102 in this embodiment includes:
步骤1021、RNC判断用户终端的速度状态是否为低速状态或稳定中速状态；如果判断结果为是，则执行步骤1022；反之，执行步骤1023。Step 1021, the RNC judges whether the speed state of the user terminal is a low speed state or a stable medium speed state; if the judgment result is yes, execute step 1022; otherwise, execute step 1023.
其中，为了便于判断用户终端的移动状态，RNC预先设定测量监测周期，以根据该测量监测周期内用户终端的速度状态判定用户终端的移动状态。其中，测量监测周期的长短可以根据实际需要灵活设置，例如如果需要较高精度的判定结果，则可以设定测量监测周期较长，反之，可以设定测量监测周期较短。Wherein, in order to facilitate judging the moving state of the user terminal, the RNC presets a measurement monitoring cycle, so as to judge the moving state of the user terminal according to the speed state of the user terminal within the measurement monitoring cycle. Wherein, the length of the measurement and monitoring period can be flexibly set according to actual needs. For example, if a higher-precision determination result is required, the measurement and monitoring period can be set to be longer; otherwise, the measurement and monitoring period can be set to be shorter.
如果在测量监测周期内，用户终端的速度状态始终为低速状态或者稳定中速状态，说明用户终端属于非高速且状态稳定的用户；反之，说明该用户终端属于高速用户或者状态不稳定的用户。If the speed state of the user terminal is always in the low-speed state or stable medium-speed state during the measurement and monitoring period, it means that the user terminal belongs to a non-high-speed user with a stable state; otherwise, it means that the user terminal belongs to a high-speed user or a user with an unstable state.
步骤1022、RNC确定用户终端在测量监测周期的移动状态为第一移动状态，并继续执行步骤103；Step 1022, the RNC determines that the mobile state of the user terminal in the measurement monitoring period is the first mobile state, and proceeds to step 103;
步骤1023、RNC确定用户终端在测量监测周期的移动状态为第二移动状态，并继续执行步骤103。Step 1023, the RNC determines that the mobility state of the user terminal in the measurement monitoring period is the second mobility state, and proceeds to step 103.
其中，处于第一移动状态的用户终端属于状态稳定的非高速用户，可能是被吸纳进高铁通信网络的公网用户，也可能是由于铁路运行特性产生的高铁通信网络下的低速用户；对于该类用户终端，公网的信号强度通常能够满足其通信需求，因此，结合一定算法在能够保证用户终端正常通信的条件下，可以考虑将该类用户终端迁移到公网中。处于第二移动状态的用户终端可能是高铁通信网络中的高速用户，也可能是因移动状态不稳定而无法被识别是高铁通信网络中还是公网中的用户终端，其中为了保证用户终端能够正常通信，因此，可将无法识别的用户终端视为高铁通信网络中的高速用户对待。基于此，为使处于第二移动状态的用户终端能够正常通信，该类用户终端只能留在高铁通信网络中，因此，对该类用户终端对应的迁移策略需要根据其实际移动方向而定。Among them, the user terminal in the first mobile state is a non-high-speed user with a stable state, and may be a public network user absorbed into the high-speed rail communication network, or may be a low-speed user under the high-speed rail communication network due to the characteristics of the railway operation; for this For such user terminals, the signal strength of the public network can usually meet their communication requirements. Therefore, it can be considered to migrate this type of user terminals to the public network under the condition that the normal communication of the user terminals can be guaranteed in combination with a certain algorithm. The user terminal in the second mobile state may be a high-speed user in the high-speed rail communication network, or it may be unable to be identified as a user terminal in the high-speed rail communication network or in the public network due to an unstable mobile state. In order to ensure that the user terminal can normally Communication, therefore, unidentifiable user terminals can be treated as high-speed users in the high-speed rail communication network. Based on this, in order to enable the user terminal in the second mobile state to communicate normally, this type of user terminal can only stay in the high-speed rail communication network. Therefore, the corresponding migration strategy for this type of user terminal needs to be determined according to its actual moving direction.
其中，RNC设定测量监测周期为分钟级，优选至少包括一个正常通话时长，正常通话时长是由RNC对大量通话时长进行平均获取的。基于此，该测量监测周期中将包括多个速度判决周期，例如包括3～4个。此时，RNC在执行步骤1021之前会连续获取多个速度判决周期内用户终端的速度状态，并判断多个速度判决周期内用户终端的速度状态是否相同。如果判断结果为相同，即多个速度判决周期内用户终端的速度状态相同，说明用户终端的移动状态已经稳定，则执行步骤1021；反之，如果多个速度判决周期内用户终端的速度状态不相同，说明用户终端的移动状态并未稳定，因此，不能盲目判定用户终端的移动状态，需要通过更长时间的测量，即进入下一个测量监测周期的第一个速度判决周期重新对用户终端的速度状态进行监测和判断。其中，每个速度判决周期的速度状态均可参见步骤101来获取。Wherein, the RNC sets the measurement and monitoring cycle to be at the minute level, preferably including at least one normal call duration, and the normal call duration is obtained by the RNC on average from a large number of call durations. Based on this, the measurement monitoring cycle will include a plurality of speed judgment cycles, for example, 3-4. At this time, before performing step 1021, the RNC will continuously obtain the speed status of the user terminal in multiple speed decision periods, and judge whether the speed status of the user terminal in the multiple speed decision periods is the same. If the judgment result is the same, that is, the speed state of the user terminal in multiple speed judgment periods is the same, indicating that the mobile state of the user terminal has stabilized, then perform step 1021; otherwise, if the speed state of the user terminal in multiple speed judgment periods is not the same , indicating that the mobile state of the user terminal is not stable. Therefore, the mobile state of the user terminal cannot be judged blindly, and a longer measurement period is required, that is, entering the first speed judgment cycle of the next measurement monitoring cycle to re-evaluate the speed of the user terminal. Status monitoring and judgment. Wherein, the speed state of each speed judgment cycle can be obtained by referring to step 101 .
在本实施方式中，通过对多个速度判决周期内用户终端的速度状态进行判断可以进一步提高判定结果的准确性和可靠性。In this embodiment, the accuracy and reliability of the judgment result can be further improved by judging the speed state of the user terminal in multiple speed judgment periods.
基于上述，本实施例步骤103的一种实施方式包括：Based on the above, an implementation manner of step 103 in this embodiment includes:
步骤1031、RNC识别用户终端的移动状态的类型；当识别出用户终端的移动状态为第一移动状态时，执行步骤1032；反之，执行步骤1035。In step 1031, the RNC identifies the type of the mobility state of the user terminal; when it recognizes that the mobility state of the user terminal is the first mobility state, execute step 1032; otherwise, execute step 1035.
步骤1032、RNC根据特性信息判断高铁通信小区的类型；即判断高铁通信小区是站台小区还是沿线小区；若是站台小区，执行步骤1033；反之，执行步骤1034。Step 1032, RNC judges the type of the high-speed rail communication cell according to the characteristic information; that is, judges whether the high-speed rail communication cell is a station cell or a cell along the line; if it is a station cell, execute step 1033; otherwise, execute step 1034.
步骤1033、RNC通过基站向用户终端发送测量控制消息，以使用户终端对所有相邻通信小区进行1G/2A事件测量和对测量控制消息中指定的相邻公网通信小区进行邻区周期测量并上报测量结果，然后执行步骤104；Step 1033, the RNC sends a measurement control message to the user terminal through the base station, so that the user terminal performs 1G/2A event measurement on all adjacent communication cells and performs adjacent cell periodic measurement on the adjacent public network communication cells specified in the measurement control message and Report the measurement result, and then perform step 104;
步骤1034、RNC通过基站向用户终端发送测量控制消息，以使用户终端对测量控制消息中指定的相邻公网通信小区进行邻区周期测量并上报测量结果，然后执行步骤104；Step 1034, the RNC sends a measurement control message to the user terminal through the base station, so that the user terminal performs adjacent cell periodic measurement on the adjacent public network communication cell specified in the measurement control message and reports the measurement result, and then executes step 104;
步骤1035、RNC通过基站向用户终端发送测量控制消息，以使用户终端对所有相邻通信小区进行1G/2A事件测量并上报测量结果，然后执行步骤104。Step 1035 , the RNC sends a measurement control message to the user terminal through the base station, so that the user terminal performs 1G/2A event measurement on all adjacent communication cells and reports the measurement results, and then executes step 104 .
具体的，当用户终端处于第一移动状态时，说明可以考虑将该用户终端迁移至公网中。但是由于该用户终端可能是公网用户，也可能是高铁通信网络中低速用户，例如：靠近或位于高铁通信小区在等待列车的用户，又例如：在列车出站或进站时随列车运行的用户，因此，不能直接将该用户终端判定为公网用户而将其迁出高铁通信网络，否则可能导致因高铁运行特性产生的低速用户出现掉话或无法正常通信的情况。Specifically, when the user terminal is in the first moving state, it indicates that the user terminal may be considered to be migrated to the public network. However, since the user terminal may be a public network user, it may also be a low-speed user in the high-speed rail communication network, for example: a user who is close to or located in a high-speed rail communication cell and waiting for a train, and for example: a train running with the train when it leaves or enters the station Users, therefore, cannot directly determine the user terminal as a public network user and move it out of the high-speed rail communication network, otherwise it may cause low-speed users due to high-speed rail operating characteristics to drop calls or fail to communicate normally.
基于此，本实施例RNC进一步根据用户终端所在高铁通信小区的特性信息判定高铁通信小区的类型；如果高铁通信小区是站台小区，那么认为该站台小区与周围的高铁通信小区(例如沿线小区)和周围的公网通信小区互为邻区。由于站台情况比较复杂，RNC确实无法准确判断出该用户终端所属的网络类别，因此，RNC为该用户终端同时配置邻区周期测量策略和1G/2A事件测量策略，并通过测量控制消息将相应测量策略以及测量对象下发给用户终端。此时，测量控制消息中同时携带邻区周期测量策略和1G/2A事件测量策略，以及分别为邻区周期测量策略和1G/2A事件测量策略指定的测量对象，通常用小区ID来表示不同测量对象。其中，邻区周期测量策略是针对用户终端为公网用户时配置的测量策略，因此，测量控制消息为该邻区周期测量策略指定的测量对象为与用户终端所在高铁通信小区相邻的公网通信小区，要求用户终端周期性的测量相邻公网通信小区的信号强度，并周期性的上报测量到的各相邻公网通信小区的信号强度给RNC。1G/2A事件测量策略是针对用户终端为高铁通信网络的低速用户时配置的测量策略，在该条件下要求根据用户终端移动方向上的信号强度对用户终端进行小区切换或迁移，因此，RNC为1G/2A事件测量策略指定的测量对象为所有与用户终端所在高铁通信小区相邻的通信小区(包括高铁通信小区和公网通信小区)，并要求用户终端测量所有相邻通信小区的信号强度，并要求用户终端在发现信号强度比当前所在高铁通信小区的信号强度大的通信小区(即第一通信小区)时上报该通信小区的标识给RNC。对RNC而言，将根据最先接收到的信息，确定用户终端的目标通信小区，即用户终端应该迁移至的通信小区，即执行步骤104。若RNC先接收到用户终端根据1G/2A事件测量上报的测量结果，则根据该结果对用户终端进行迁移；反之，根据用户终端进行邻区周期测量上报的测量结果对用户终端进行迁移。Based on this, the RNC in this embodiment further determines the type of the high-speed rail communication cell according to the characteristic information of the high-speed rail communication cell where the user terminal is located; The surrounding public network communication cells are adjacent to each other. Due to the complex situation of the station, the RNC cannot accurately determine the network category to which the user terminal belongs. Therefore, the RNC configures the adjacent cell period measurement strategy and the 1G/2A event measurement strategy for the user terminal at the same time, and through the measurement control message. The policies and measurement objects are delivered to user terminals. At this time, the measurement control message carries both the neighbor cell cycle measurement strategy and the 1G/2A event measurement strategy, as well as the measurement objects specified for the neighbor cell cycle measurement strategy and the 1G/2A event measurement strategy respectively. Cell IDs are usually used to indicate different measurement object. Among them, the adjacent cell cycle measurement strategy is a measurement strategy configured for the user terminal as a public network user. Therefore, the measurement object specified by the adjacent cell cycle measurement strategy in the measurement control message is the public network adjacent to the high-speed rail communication cell where the user terminal is located. The communication cell requires the user terminal to periodically measure the signal strength of adjacent public network communication cells, and periodically report the measured signal strength of each adjacent public network communication cell to the RNC. The 1G/2A event measurement strategy is a measurement strategy configured when the user terminal is a low-speed user of the high-speed rail communication network. Under this condition, it is required to perform cell handover or relocation of the user terminal according to the signal strength in the moving direction of the user terminal. Therefore, the RNC is The measurement objects specified by the 1G/2A event measurement strategy are all communication cells adjacent to the high-speed rail communication cell where the user terminal is located (including the high-speed rail communication cell and the public network communication cell), and the user terminal is required to measure the signal strength of all adjacent communication cells, And require the user terminal to report the identification of the communication cell to the RNC when it finds a communication cell (that is, the first communication cell) whose signal strength is greater than the signal strength of the current high-speed rail communication cell. For the RNC, according to the first received information, it will determine the target communication cell of the user terminal, that is, the communication cell to which the user terminal should migrate, that is, step 104 is executed. If the RNC first receives the measurement result reported by the user terminal according to the 1G/2A event measurement, it will relocate the user terminal according to the result; otherwise, it will relocate the user terminal according to the measurement result reported by the user terminal for neighboring cell cycle measurement.
如果该高铁通信小区为沿线小区，且其周围相邻通信小区包括站台小区和公网小区时，在该情况下，可以确定处于第一移动状态的用户终端属于铁路线外的用户，即为被吸纳到高铁通信网络中的公网用户，此时，RNC为该用户终端配置邻区周期测量策略，并通过测量控制消息将相应测量策略以及测量对象下发给用户终端。此时，测量控制消息中携带有邻区周期测量策略以及为该策略指定的测量对象，并要求用户终端周期性测量相邻公网通信小区的信号强度，并周期性上报给RNC，以使RNC根据上报的测量结果确定用户终端的目标通信小区，即执行步骤104。If the high-speed rail communication cell is a cell along the line, and its surrounding adjacent communication cells include a station cell and a public network cell, in this case, it can be determined that the user terminal in the first mobile state belongs to a user outside the railway line, that is, it is a blocked For a public network user absorbed into the high-speed rail communication network, at this time, the RNC configures a neighbor cell periodic measurement strategy for the user terminal, and sends the corresponding measurement strategy and measurement objects to the user terminal through a measurement control message. At this time, the measurement control message carries the neighbor cell periodic measurement strategy and the measurement object specified for the strategy, and requires the user terminal to periodically measure the signal strength of the adjacent public network communication cell and report it to the RNC periodically, so that the RNC The target communication cell of the user terminal is determined according to the reported measurement result, that is, step 104 is executed.
其中，当用户终端处于第二移动状态时，说明该用户终端可能为具有高速标识的高铁通信网络中的高速用户，也可能为提速或降速既没有高速标识，也没有稳定于中速而被等同于高铁通信网络中的高速用户对待的用户终端。此时，RNC为该类用户配置1G/2A事件测量策略，并通过测量控制消息将相应测量策略以及测量对象下发给用户终端。在该条件下，测量控制消息包括为用户终端配置的1G/2A事件测量策略和为该测量策略指定的测量对象，该测量对象为所有相邻通信小区，并要求用户终端测量所有相邻通信小区的信号强度，并发现信号强度大于当前所在高铁通信小区的信号强度的通信小区(即第一通信小区)时向RNC上报该第一通信小区的标识，以使RNC继续执行步骤104。Wherein, when the user terminal is in the second moving state, it means that the user terminal may be a high-speed user in the high-speed rail communication network with a high-speed identification, or it may be speed-up or deceleration without a high-speed identification or stable at a medium speed. It is equivalent to the user terminal treated by high-speed users in the high-speed rail communication network. At this time, the RNC configures a 1G/2A event measurement policy for this type of user, and delivers the corresponding measurement policy and measurement objects to the user terminal through a measurement control message. Under this condition, the measurement control message includes the 1G/2A event measurement strategy configured for the user terminal and the measurement object specified for the measurement strategy, the measurement object is all adjacent communication cells, and the user terminal is required to measure all adjacent communication cells When finding a communication cell (i.e. the first communication cell) whose signal strength is greater than the signal strength of the current high-speed rail communication cell, report the identity of the first communication cell to the RNC, so that the RNC continues to perform step 104.
基于上述方案，本实施例步骤104的一种实施方式包括：Based on the above solution, an implementation manner of step 104 in this embodiment includes:
步骤1041、RNC接收用户终端通过基站上报的测量结果，并判断该测量结果的类型；如果测量结果为用户终端进行周期测量上报的相邻公网通信小区的信号强度时，，执行步骤1042；如果测量结果为用户终端进行1G/2A事件测量上报的第一通信小区的标识，执行步骤1043。Step 1041, RNC receives the measurement result reported by the user terminal through the base station, and judges the type of the measurement result; if the measurement result is the signal strength of the adjacent public network communication cell reported by the user terminal for periodic measurement, execute step 1042; if The measurement result is the identity of the first communication cell where the user terminal performs 1G/2A event measurement and reports, and step 1043 is executed.
步骤1042、RNC从相邻公网通信小区中选择信号强度大于预设公网信号强度门限值的通信小区作为目标通信小区，并将用户终端迁移至该目标通信小区，结束此次迁移操作；Step 1042, the RNC selects a communication cell whose signal strength is greater than the preset public network signal strength threshold from adjacent public network communication cells as the target communication cell, and migrates the user terminal to the target communication cell, and ends the migration operation;
其中，RNC预先配置了公网信号强度门限值，只要公网小区的信号强度大于该预设门限值，用户终端迁移至该通信小区时可以正常通信，即保证用户终端进行迁移之后仍能正常通信。Among them, the RNC pre-configures the public network signal strength threshold value, as long as the signal strength of the public network cell is greater than the preset threshold value, the user terminal can communicate normally when migrating to the communication cell, that is, it is guaranteed that the user terminal can still communicate after the migration. Normal communication.
步骤1043、RNC将标识对应的第一通信小区作为目标通信小区，并将用户终端迁移至该目标通信小区，结束此次迁移操作。Step 1043, the RNC identifies the corresponding first communication cell as the target communication cell, and migrates the user terminal to the target communication cell, and ends the migration operation.
本实施例的高铁通信网络中用户迁移的方法，根据用户终端的速度值确定用户终端的移动状态，根据用户终端的移动状态和所在高铁通信小区的类型(即用户终端所处位置)向用户终端发送测量控制消息以配置用户终端的测量策略，根据用户终端返回的测量结果对用户终端进行迁移，可以将低速用户迁出高铁通信网络，降低了低速用户对高铁通信网络资源的消耗，降低了对高速用户的影响；另外，本实施例仅对处于第一移动状态的用户终端配置邻区周期测量策略，降低了网络配置复杂度，同时与所有用户终端均配置邻区周期测量策略相比，减少了空口信令的传输；再者，本实施例在无法准确判定处于第一移动状态的用户终端是否为公网用户时，同时为用户终端配置邻区周期测量策略和1G/2A事件测量策略，保证了由于列车运行特性造成的低速用户能够留在高铁通信网络，保证了其通话的连续性。In the method for user migration in the high-speed rail communication network of this embodiment, the mobile state of the user terminal is determined according to the speed value of the user terminal, and the user terminal is sent to the user terminal according to the mobile state of the user terminal and the type of the high-speed rail communication cell where it is located (ie, the location of the user terminal). Send measurement control messages to configure the measurement strategy of the user terminal, and migrate the user terminal according to the measurement results returned by the user terminal, so that low-speed users can be moved out of the high-speed rail communication network, reducing the consumption of low-speed users on high-speed rail communication network resources The impact of high-speed users; in addition, this embodiment only configures the neighbor cell cycle measurement strategy for the user terminal in the first mobile state, which reduces the complexity of network configuration, and at the same time reduces the Furthermore, in this embodiment, when it is impossible to accurately determine whether the user terminal in the first mobile state is a public network user, the adjacent cell cycle measurement strategy and the 1G/2A event measurement strategy are configured for the user terminal at the same time, It ensures that low-speed users due to the characteristics of train operation can stay in the high-speed rail communication network and ensure the continuity of their calls.
