[0163] Reference figure 1 As shown, the method for updating the idle state tracking area in the embodiment of the present invention, which is applied to the mobility management function MM, includes:

[0164] Step 101: Receive a tracking area update TAU request message sent by a user equipment UE.

[0165] In order to maintain the mobility of the UE, the network needs to identify and track the location of the UE, or the UE notifies the network to update its location, that is, the UE triggers the TAU update procedure.

[0166] Here, the UE triggers the TAU update procedure, the UE sends a TAU request message to the RAN (Radio Access Network, radio access network), and the RAN forwards the TAU request message to the MM.

[0167] Among them, the TAU request message may include the user ID user ID, the MM context ID MM context ID, the BS ID of the base station where the UE is currently located, or other IDs.

[0168] Step 102: When it is determined that the location of the UE changes accord...

[0178] The method for updating the idle state tracking area in the embodiment of the present invention aims at that the coverage area of ​​the TA list is the same as the service area of ​​the SM, and the signaling plane connection between the UE and the core network and the user plane connection between the UE and the core network are maintained Case. In this case, the TAU only releases air interface resources (RAN-side resources).

[0179] Reference figure 2 As shown, the method for updating the idle state tracking area in the embodiment of the present invention, which is applied to the mobility management function MM, includes:

[0180] Step 201: Receive a tracking area update TAU request message sent by user equipment UE.

[0181] In order to maintain the mobility of the UE, the network needs to identify and track the location of the UE, or the UE notifies the network to update its location, that is, the UE triggers the TAU update procedure.

[0267] The method for updating the idle state tracking area in the embodiment of the present invention aims at the TA list whose coverage area is the same as the SM service area, and the signaling plane connection between the UE and the core network is maintained, but the UE and the user plane connection of the core network are not connected. Keep the situation. The TAU in this case releases air interface resources (RAN-side resources).

[0268] Reference Figure 7 As shown, the method for updating the idle state tracking area in the embodiment of the present invention, which is applied to the mobility management function MM, includes:

[0269] Step 701: Receive a tracking area update TAU request message sent by a user equipment UE.

[0270] In order to maintain the mobility of the UE, the network needs to identify and track the location of the UE, or the UE notifies the network to update its location, that is, the UE triggers the TAU update procedure.

Abstract

The invention provides an idle-state tracking area updating method and device, and relates to the communication field. The problem that the method and technology about idle-state TAU after the MM is separated from SM is inexistent in the prior art is solved. The method is applied to the MM, and comprises the following steps: receiving a tracking area updating TAU request message sent by user equipment UE; updating location information of the UE when determining a fact that the location of the UE is changed according to the current location information carried in the TAU request message, and sending an indication message for modifying a user plane path of the UE to a session management function SM according to the current location information of the UE when determining a fact that the userplane path of the UE needs to reselect. The scheme provided by the invention realizes the TAU of the idle-state UE after the MM is separated from the SM.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for updating an idle state tracking area. Background technique [0002] The 5G network supports the separation of gateway control and forwarding, and separation of MM (Mobility Management, mobility management) functions and SM (Session Management, session management) functions. The separation of control and forwarding means that the control and forwarding functions of the mobile network are logically divided, and different logical network elements are responsible for corresponding functions, so as to achieve centralized control of functions, flexible resource allocation, flexible business deployment, control plane and The user plane can evolve and other characteristics separately. The control function is undertaken by the centralized controller. The separated user plane can be deployed in a distributed manner according to business requirements, and efficient...
