specific Embodiment approach

[0068] Further, the behavior of the AMF after receiving the connection state management policy sent by the PCF is as follows: determine whether to control the UE to activate MICO mode according to the connection state management policy, and / or determine the periodic registration timer of the UE duration. Specific implementation methods include:

[0069] (1) When detecting that the connection state management policy includes that the UE is suitable for activating MICO mode, sending a configuration update command to the UE, where the configuration update command includes an indication of activating MICO mode;

[0070] (2) When detecting that the connection state management policy includes the duration of the periodic registration timer of the UE, sending the duration of the periodic registration timer to the UE during the registration update process of the UE.

Embodiment approach

[0071] Further, after receiving the connection state transition policy sent by the PCF, the UE determines whether to control itself to activate the MICO mode according to the connection state transition policy. Specific implementations include:

[0072] (1) When the connection state transition policy includes a location range in which the UE can activate MICO mode, the UE initiates a registration process to the network side after detecting that it has entered the location range, and requests to activate the MICO mode; After detecting that it has left the location range, it initiates a registration process to the network side and requests to cancel the MICO mode;

[0073] (2) When the connection state transition policy includes a time window in which the UE has no downlink data, the UE initiates a registration process to the network side after detecting that the time window starts, and requests to activate the MICO mode; After the end of the time window or within a predetermin...

Embodiment 1

[0079] This embodiment introduces the process of the PCF determining the UE's connection state management policy and notifying the AMF, refer to figure 2 , the specific process is as follows:

[0080] S11: The NWDAF provides the communication duration model to the PCF.

[0081] S12: The PCF determines a connection state management policy (for example, whether the UE is suitable for activating MICO mode, or the duration of the periodic registration timer of the UE) according to the communication duration model, and sends the policy to the AMF.

[0082] According to different policies, the behavior of AMF is different: if the policy is that the UE is suitable for activating MICO mode, then perform steps S13 and S14; if the policy includes the UE's periodic registration timer duration, then perform step S14; if the policy includes the UE's periodic If the length of the permanent registration timer is also suitable for activating the MICO mode, execute S13 and S14.

Abstract

The invention provides a method and a device for controlling a UE communication mode, which are used for solving the technical problem of poor flexibility of controlling the UE communication mode in the prior art. The method comprises the steps of enabling an NWDAF to obtain a communication duration model between the UE and a network side; and sending the communication duration model to a PCF, sending the communication duration model to the PCF, so that the PCF determines a connection state management strategy of the UE according to the communication duration model; notifing the AMF of the connection state management strategy, and / or, determining a connection state conversion strategy of the UE according to the communication duration model, and notifying the UE of the connection state conversion strategy; or, sending the communication duration model to the AMF, so that the AMF adjusts the duration of the periodic registration timer and / or requests the UE to activate the MICO mode according to the communication duration model.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for controlling UE communication mode. Background technique [0002] With the substantial growth of wireless traffic and services, the fourth generation (4G) mobile wireless network will not be able to meet future network requirements, thus promoting the research of the fifth generation (5G) mobile wireless network to cope with future diversified and differentiated services great challenge. [0003] In the existing 5G network, the communication mode of the user equipment (User Equipment, UE) is generally controlled by the network side based on pre-configured information. For example, the authentication management function (Authentication Management Function, AMF) decides whether to allow the UE to activate the mobile terminal initiated connection mode only ( Mobile InitiatedConnection Only mode, MICO mode). [0004] In practical applications, the...
