Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the specific implementation manners of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

It should be noted that the terms "first" and "second" in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and not necessarily used to describe a specific order or sequence; Moreover, the embodiments and the features in the embodiments in the present disclosure can be combined with each other arbitrarily if there is no conflict.

In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present disclosure and has no specific meaning by itself. Therefore, 'module', 'part' or 'unit' may be used in combination.

CIOT (Cellular Internet of Things, Cellular Internet of Things) is a data transmission optimization technology. CIOT data can be carried on the control plane (such as non-access layer protocol data unit (NAS PDU)) or transmitted on the user plane ( Such as UE bearer) transmission. CIOT where data is carried on the control plane is called control plane CIOT optimization. CIOT optimization on the control plane does not need to establish a UE bearer in the radio access network for power saving, nor does it need to establish a wireless security context in the radio access network, and encryption is performed in the core network. Through the CIOT optimization of the control plane, the signaling overhead required to establish the bearer of the user terminal UE can be omitted, thereby shortening the time delay for the UE to access the network or for the UE to send and receive data. The CIOT in which data is carried on the user plane is called user plane CIOT optimization. Through CIOT optimization on the user plane, when the UE is no longer active, the UE context is suspended instead of being deleted. When there is a demand for data transmission, the UE context is restored instead of being newly created, thereby reducing the signaling overhead of UE connection establishment or UE bearer establishment, thereby shortening the delay of UE accessing the network or UE sending and receiving data. For CIOT communication services, it can be used on NB-IOT.

It should be noted that in order to meet the extremely low power consumption requirements of narrowband Internet of Things (NB-IoT) terminal equipment based on CIOT technology, an enhanced discontinuous reception (Extended DRX, eDRX) technology, the embodiments of the present disclosure are also applicable to the eDRX power saving mode.

Combined with Figure 1-3, it illustrates the power-saving technical solution applied to CIOT in related technologies, in which:

FIG. 1 is a schematic diagram of power saving of a terminal using only the MICO technology. When the system and the terminal are in an idle state of communication, the terminal enters the MICO mode. At this time, the NB-IoT terminal is in idle mode, and the state is similar to shutdown, except that the terminal is still in the registration state in the network. When reconnecting, there is no need to reattach or re-establish a packet data network (PDN) connection. Under MICO, the terminal periodically reports data services. The terminal enters the connection state when there is a periodic tracking area update or when there is uplink data to be sent. The terminal in this mode reports data periodically and is idle 99% of the time. It is only suitable for infrequent data transmission services, and there will be a corresponding delay for called services.

FIG. 2 is a schematic diagram of power saving for a terminal using only the eDRX technology. eDRX is a technology that prolongs the paging cycle of the core network to improve the power saving capability of the terminal. Under normal circumstances, the AMF uses periodic downlink TAU signaling to paging the terminal. When the UE is not in the paging time window, the AMF does not attempt to page the UE. When the eDRX mode is used, the paging cycle time of the TAU is extended, and the idle state time of the terminal is increased. When there is downlink data in the network in the idle state, the AMF will instruct the session management function (Session Management Function, SMF for short) network element to cache.

It can be understood from this that the reachable time of the downlink data is the paging time of the TAU signal in the active state. Combined with Figure 3a and Figure 3b, Figure 3a and Figure 3b combine MICO and eDRX two power-saving technologies. In related technologies, when both MICO and eDRX technologies are used at the same time, when the terminal periodically reports data MICO, the terminal 99% The time is in the idle state, that is, the dormant state, causing the idle state to be too long, resulting in multiple TAU paging cycles before the AMF can reach the avtice state that can activate the terminal and send downlink data. Therefore, the waiting time for the terminal response is too long, and the pressure on the data cache is high.

In order to solve the above problems, please refer to FIG. 4, which is a schematic flowchart of a method for configuring a power saving mode provided by an embodiment of the present disclosure. The power saving mode includes only the connection MICO power saving mode initiated by the mobile terminal and the discontinuous Connecting to the DRX power saving mode, the method includes step S401 and step S402.

Wherein, in order to improve the power saving function of the terminal, the DRX power saving mode adopted in this embodiment may be an improved eDRX power saving mode.

In step S401, the MICO period of the MICO power saving mode is determined.

In one embodiment, the MICO period can be reasonably determined based on the service requirements of the terminal, so as to reduce the response time of the terminal while achieving the purpose of energy saving of the terminal, for example, counting the frequency of sending and receiving service data packets of the terminal within a certain period of time , and/or the sending and receiving interval of service data packets, etc., and then determine the MICO period according to the statistical results.

In step S402, the DRX cycle of the DRX power saving mode is determined based on the MICO cycle, so that the DRX cycle is an integer multiple of the MICO cycle.

It should be noted that, in some embodiments, the DRX cycle of the DRX power saving mode can be determined first, and then the MICO cycle of the MICO power saving mode can be determined according to the DRX cycle of the DRX power saving mode, so that the DRX cycle is an integer of the MICO cycle times to achieve synchronization between the eDRX cycle and the MICO cycle.

Further, the MICO cycle includes the active time actvie time and the idle time of the terminal, and the DRX cycle includes the paging cycle Paging Cycle. In this embodiment, determining the MICO cycle of the MICO power-saving mode includes the following steps:

Determine the activation time and sleep time period of the terminal in the MICO power saving mode.

In this embodiment, determining the DRX cycle of the DRX power-saving mode based on the MICO cycle includes the following steps:

The paging cycle for sending the paging message to the terminal in the DRX power saving mode is determined based on the MICO cycle of the MICO power saving mode.

By first determining the MICO cycle, and then determining the DRX cycle according to the MICO cycle, the synchronization between the MICO cycle and the DRX cycle of the two power-saving modes can be realized, and then the DRX paging time window and MICO mode that can make the AMF initiate paging to the terminal Synchronize the terminal actvie time window to reduce the response time of the terminal and relieve the pressure on the data cache.

This embodiment uses the application of AMF to realize the power saving function of CIOT terminals as an example to illustrate the principle. For AMF and CIOT terminals.

Compared with related technologies, only MICO power-saving mode or DRX/eDRX power-saving mode is used, resulting in poor terminal power-saving effect, and when both MICO power-saving mode and DRX/eDRX power-saving mode are used at the same time, when the terminal periodically reports data MICO At this time, the terminal is in the idle state for 99% of the time, that is, the dormant state, causing the idle state to be too long, resulting in multiple TAU paging cycles before the AMF can reach the avtice state that can activate the terminal and send downlink data. Therefore, the waiting time for the terminal response is too long, and the pressure on the data cache of the SMF is relatively high. In this embodiment, on the basis of adopting the MICO power-saving mode and the DRX/eDRX power-saving mode, MICO and eDRX time coordination is performed, and the MICO period is determined first, and then the eDRX period is determined according to the MICO period, so as to ensure that the eDRX paging time window and MICO In this mode, the terminal actvie time window is synchronized. In this way, the TAU can be placed in the active time period of the terminal, thereby improving paging efficiency and reducing or even eliminating downlink data buffering.

Please refer to FIG. 5. FIG. 5 is a schematic flow diagram of a CIOT power saving method provided by an embodiment of the present disclosure. The CIOT terminal is configured with only the connection MICO power saving mode initiated by the mobile terminal and the enhanced discontinuous connection DRX node. Electric mode, the method includes steps S501-S503:

In step S501, the MICO period of the MICO power saving mode is determined.

In one embodiment, the MICO period can be reasonably determined in combination with the service requirements of the terminal, for example, the frequency of sending and receiving service data packets of the terminal within a certain period of time, or the interval between sending and receiving service data packets, etc., and then according to the statistics The result determines the MICO period.

In step S502, the DRX cycle is determined based on the MICO cycle, so that the DRX cycle is an integer multiple of the MICO cycle; and,

In step S503, a paging message is sent to the CIOT terminal based on the DRX cycle.

It should be noted that, in some embodiments, the DRX cycle of the DRX power saving mode can be determined first, and then the MICO cycle of the MICO power saving mode can be determined according to the DRX cycle of the DRX power saving mode, so that the DRX cycle is an integer of the MICO cycle times to achieve synchronization between the eDRX cycle and the MICO cycle.

Further, the MICO cycle includes the active time actvie time and the idle time of the terminal, and the DRX cycle includes the paging cycle Paging Cycle. In this embodiment, determining the MICO cycle of the MICO power-saving mode includes the following steps:

Determine the activation time and sleep time period of the terminal in the MICO power saving mode.

In this embodiment, determining the DRX cycle of the DRX power-saving mode based on the MICO cycle includes the following steps:

The paging cycle for sending the paging message to the terminal in the DRX power saving mode is determined based on the MICO cycle of the MICO power saving mode.

By first determining the MICO cycle, and then determining the DRX cycle according to the MICO cycle, the synchronization between the MICO cycle and the DRX cycle of the two power-saving modes can be realized, and then the DRX paging time window and MICO mode that can make the AMF initiate paging to the terminal Synchronize the terminal actvie time window to reduce the response time of the terminal and relieve the pressure on the data cache.

Specifically, the method is applied to an AMF network element with an access and mobility management function. With the continuous development of communication technology, the above CIOT power saving method can also be applied to similar devices.

In this embodiment, MICO and DRX/eDRX time coordination is carried out on the basis of adopting the MICO power saving mode and DRX/eDRX power saving mode, and by first determining the MICO cycle, and then determining the DRX/eDRX cycle according to the MICO cycle, it is determined to ensure that eDRX seeks The paging time window is synchronized with the actvie time window of the terminal in MICO mode, and the AMF sends a paging message to the CIOT terminal based on the DRX/eDRX cycle. In this way, the TAU can be exactly in the actvietime time period of the terminal, thereby improving paging efficiency and reducing or exempting downlink data buffering.

Please refer to FIG. 6. FIG. 6 is a schematic flowchart of another CIOT power saving method provided by an embodiment of the present disclosure. In order to further ensure that the TAU paging signaling is in the actvie time period of the terminal, in the previous embodiment In this embodiment, the DRX cycle is determined from the first TAU signal in the activation time state of the CIOT terminal, specifically, after determining the MICO cycle of the MICO power-saving mode (step S501), and determining the DRX cycle based on the MICO cycle Before the period (step S502), the following step S601 is also included.

In step S601, it is determined whether the first TAU signal for initiating paging to the CIOT terminal is in the activation time state of the CIOT terminal, if so, perform step S502 to determine the DRX cycle based on the MICO cycle, otherwise, perform step S602.

In step S602, continue to monitor the next TAU signal that initiates paging to the CIOT terminal;

In step S603, it is judged whether the next TAU signal is in the activation time state of the CIOT terminal, if so, then execute step S502, otherwise return to step S602 and continue to monitor the next TAU signal until the first activation at the CIOT terminal is detected For the TAU signal in the time state, go to step S502.

In this embodiment, the DRX cycle is determined based on the MICO cycle when it is detected that the TAU paging signal sent by the AMF to the terminal is the terminal activation time, so as to facilitate the determination of the DRX activation time and sleep time cycle, and after one or several The next cycle after the MICO paging cycle initiates paging to the terminal, and the next cycle must fall into the activation time cycle of the terminal. Compared with the above-mentioned embodiment, it can further ensure that the TAU paging signaling is in the active time of the terminal in the time period.

As shown in Figure 7, the paging cycle of eDRX is set to an integer multiple of the idle (state) time+active time of CIOT when the first TAU signal of the paging cycle is activated at the terminal's actvie (state) time, that is eDRX is a multiple of the CIOT cycle. In the figure, Paging Cycle Time=n*(idle state time+active statetime). In this way, it can be ensured that the subsequent TAU is just in the actvie time period of the terminal, thereby improving paging efficiency and reducing or eliminating downlink data buffering.

Further, in this embodiment, by synchronously sending the MICO cycle and the eDRX cycle to the terminal, it is convenient for the terminal to report a power saving request to the AMF when generating a power saving demand. After determining the DRX cycle based on the MICO cycle, the following steps are also included: step:

Send configuration information to the CIOT terminal, where the configuration information carries the MICO cycle and the DRX cycle.

In one embodiment, by sending configuration information to the terminal, the terminal can also participate in the specific configuration of the MICO cycle and the DRX cycle/eDRX cycle, for example, the terminal negotiates with the core network to determine that the DRX/eDRX cycle is the MICO cycle. The specific multiple of the period, AMF adjusts the value of eDRX on the core network side to ensure that the eDRX paging window and the terminal actvietime window are synchronized, thereby reducing terminal response time and data delay. In this way, AMF does not need to use SMF for data caching , reduce the complexity of the signaling process and the terminal response time, and improve the reliability of data transmission.
