Description
Technical Field
The invention relates to the technical field of communication, in particular to a heterogeneous system service self-adaptive switching method and a base station.
Background
This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present invention, and is believed to provide the reader with useful background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that the description in this section is for purposes of illustration and is not an admission of prior art.
In an area with poor or no coverage of a Network signal of an LTE (Long Term Evolution), a UE (User Equipment) can implement inter-operation between the LTE and other systems, such as UTRA (universal terrestrial radio access) and Geran (GSM EDGE radio access Network GSM global system for mobile communications) in a moving process, so as to reduce a dropped call rate of a mobile Network and improve User satisfaction; currently, Geran mainly carries voice and short message services, UTRA can carry a small amount of voice plus PS (Packet Service) services with medium and low partial rates, LTE can carry PS services and voice (voice) services with high rates, and by interoperation between systems, shunting of different services of different users can be effectively realized, network resource waste is avoided, and the utilization rate of each network resource is improved. The current implementation scheme is to implement the inter-system operation by specifying the target network of the data service and the voice service, for example, the target network of the voice service is set as Geran, and the target network of the data service is set as UTRA. However, there are some situations that make it impossible for the terminal to interoperate with the target network, for example, when the terminal is performing a voice service of a volte, the serving cell does not have a neighboring cell of Geran but has a neighboring cell of UTRA, or the terminal does not have a capability of interoperating with Geran but has a capability of UTRA. At this time, direct offline or continuous retention in the coverage edge area of LTE occurs, which greatly affects user perception. The scheme provides a scheme for self-adaptive selection of a target network for service system interoperation, and the heterogeneous systems interoperate to a non-target network under the condition that the capacity of a related target network is not available or a neighboring cell is not configured.
Some of the current solutions are to add target network settings for data traffic and voice traffic at the base station side. Firstly, judging the service type, if the load with QCI equal to 1 exists, the load is considered as voice service, if the priority of the voice service is high, the inter-system interoperation strategy of the voice service is followed, and if the load with QCI equal to 1 does not exist, the inter-system interoperation strategy of the data service is followed. A weak coverage area, A2 (voice or data) reporting, the base station judges a service target network, if the UE capability supports interoperation to the target network, checks whether the cell is configured with an adjacent frequency adjacent cell of the target network, and if so, issues a B2 event of the target network; otherwise, remaining in the original cell; and after the UE measures B2 and reports B2, the base station performs the inter-operation process of the inter-system according to the selected adjacent cell. In weak fields, if the UE capability does not support the inter-operation to the target network, it remains in the original cell and is likely to cause a call drop in a degraded environment. If the cell is not configured with the neighboring cell of the target network, the cell is left in the original cell, and call drop is easily caused in a deteriorated environment.

Detailed Description
In order to make the objects, 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 with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2, the present invention provides a method for adaptive handover of inter-system services, including: acquiring the user terminal capability of a service target network; if the user terminal capability has the function of switching to the target network; performing inter-system operation or staying in the original cell according to whether the base station configures the target network neighboring cell; if the user terminal capability does not have the switching to the target network; determining whether to perform different system operation or stay in the original cell according to the non-service target network supporting capability of the user terminal. The following provides a detailed description of the present invention and the method for adaptive handover of inter-system services.
In the invention, the service type needs to be judged first when the heterogeneous system service self-adaptive switching is executed. Specifically, for example: if the load bearing with QCI being 1 exists, the load bearing is regarded as voice service, and the priority of the voice service is high, and the inter-system interoperation strategy of the voice service is adopted; and if the load with QCI equal to 1 does not exist, according to the inter-system interoperation strategy of the data service.
In the weak coverage area, as shown in fig. 3, the ue sends a measurement report to the base station, for example, the ue sends an a2 (voice or data) event message report to the base station. The a2 event message indicates that the serving cell is worse than an absolute threshold; this event may be used to turn on measurements between certain cells, and handover or the like may occur after the a2 event. Further, the base station acquires the user terminal capability of the service target network; if the user terminal capability has the function of switching to the target network; performing inter-system operation or staying in the original cell according to whether the base station configures the target network neighboring cell; if the user terminal capability does not have the switching to the target network; determining whether to perform different system operation or stay in the original cell according to the non-service target network supporting capability of the user terminal.
Specifically, as shown in fig. 3, performing inter-system operation or staying in the original cell according to whether the base station configures the target network neighboring cell includes: if the base station configures a target network neighboring cell, performing inter-system operation; and if the base station is not configured with the target network adjacent cell, determining whether to perform different system operation or stay in the original cell according to the non-service target network supporting capability of the user terminal.
As shown in fig. 3, determining whether to perform inter-system operation or stay in the original cell according to the non-service target network capability supported by the user equipment includes: if the user terminal supports the non-service target network, performing inter-system operation according to whether the non-service target network configures a target network neighboring cell; if the user terminal does not support the non-service target network, staying in the original cell.
As shown in fig. 3, performing inter-system operation according to whether the non-service target network configures a target network neighboring cell includes: and if the non-target network is configured with the adjacent cell, performing inter-system operation according to the selected adjacent cell. And if the non-target network is not configured with the adjacent cell, counting the number of the adjacent cells configured by the non-target network reported by the terminal, and automatically adding the non-target network adjacent cell after the number exceeds a configurable threshold so as to carry out inter-system operation. Specifically, after the number of times of the neighbor cells configured by the non-target network reported by the base station statistics terminal exceeds the configurable threshold, the base station triggers an automatic adding process of the neighbor cells of the non-target network, and after the automatic adding of the neighbor cells is completed, the inter-system interoperation process is performed.
After the base station switches the user terminal to the different system network, the base station sends a measurement and control message of a target network type to the user terminal, and the user terminal measures and uploads a measurement report to the base station. For example, the user terminal sends a B2 event message to the base station. The B2 event message shows that the serving cell is 1 worse than the absolute threshold, the neighbor cell is 2 better than the absolute threshold, and the service cell is used for measuring the cells of the different systems with the same or low priority, and after the base station receives the B2 event message reported by the user terminal, the base station performs the interoperation process of the different systems according to the selected neighbor cell.
In order to further embody the superiority of the inter-system service adaptive handover method provided by the present invention, the present invention further provides an inter-system service adaptive handover base station applying the above method, as shown in fig. 4, the base station includes: a user terminal capability obtaining unit, configured to obtain a user terminal capability of a service target network; the target network neighbor cell detection unit is used for performing inter-system operation or staying in an original cell according to whether the base station configures the target network neighbor cell when the user terminal capability has the capability of being switched to the target network; the user terminal supports the non-service target network ability detection unit, which is used to determine whether to perform different system operation or stay in the original cell according to the non-service target network ability supported by the user terminal when the user terminal ability is not switched to the target network. The following will explain the inter-system service adaptive handover base station provided by the present invention in detail. Similar to the above-mentioned adaptive switching method for inter-system services, the working principle and working process of the adaptive switching base station for inter-system services provided by the present invention can be referred to and executed, and are not repeated again.
In the invention, the service type needs to be judged first when the heterogeneous system service self-adaptive switching is executed. Specifically, for example: if the load bearing with QCI being 1 exists, the load bearing is regarded as voice service, and the priority of the voice service is high, and the inter-system interoperation strategy of the voice service is adopted; and if the load with QCI equal to 1 does not exist, according to the inter-system interoperation strategy of the data service.
In the weak coverage area, as shown in fig. 3, the ue sends a measurement report to the base station, for example, the ue sends an a2 (voice or data) event message report to the base station. The a2 event message indicates that the serving cell is worse than an absolute threshold; this event may be used to turn on measurements between certain cells, and handover or the like may occur after the a2 event. Further, the base station acquires the user terminal capability of the service target network; if the user terminal capability has the function of switching to the target network; performing inter-system operation or staying in the original cell according to whether the base station configures the target network neighboring cell; if the user terminal capability does not have the switching to the target network; determining whether to perform different system operation or stay in the original cell according to the non-service target network supporting capability of the user terminal.
In the present invention, the target network neighbor cell detection unit includes: and the non-service target network capability detection unit is used for determining whether to carry out different system operation or stay in the original cell according to the non-service target network capability supported by the user terminal when the base station is not configured with the target network neighbor cell.
In the invention, the unit for detecting the network capability of the user terminal supporting the non-service target comprises: and the non-service target network neighbor cell detection unit is used for performing inter-system operation according to whether the non-service target network configures a target network neighbor cell or not when the user terminal supports the non-service target network.
In the invention, the non-service target network neighbor cell detection unit comprises: and the non-target network neighbor cell adding unit is used for counting the number of neighbor cells configured by the non-target network reported by the terminal when the non-target network is not configured with neighbor cells, adding the non-target network neighbor cells after the number exceeds a configurable threshold, and performing inter-system interoperation.
After the base station switches the user terminal to the different system network, the base station sends a measurement and control message of a target network type to the user terminal, and the user terminal measures and uploads a measurement report to the base station. For example, the user terminal sends a B2 event message to the base station. The B2 event message shows that the serving cell is 1 worse than the absolute threshold, the neighbor cell is 2 better than the absolute threshold, and the service cell is used for measuring the cells of the different systems with the same or low priority, and after the base station receives the B2 event message reported by the user terminal, the base station performs the interoperation process of the different systems according to the selected neighbor cell.
In summary, the inter-system service adaptive handover method and the base station provided by the present invention interoperate with a non-preferred target network without the capability of a related target network or without configuring an adjacent cell. The invention adopts a self-adaptive mode to select the interoperation target network of the voice or data service, reduces the disconnection rate, utilizes the on-site network deployment to the maximum extent and improves the user perception.
