Problems solved by technology

[0005] (1) No mobility: UE is static or semi-static, and can only access the network through a fixed access point, and such UE has no Tracking Area (TA) change;
[0006] (2) Low mobility: UE can move within a specified or expected TA;
[0009] But at present, there is no specific solution to realize UE-based mobile class division TA

[0070] see figure 1 As shown, the first embodiment of the present invention provides a location management method, which is applied to the main body of the CS control plane, and includes the following steps 101-103, which are described in detail below.

[0071] Step 101: Determine the UE's mobility class.

[0072] In the embodiment of the present invention, when the CS control plane main body determines the UE's mobility level, it can determine the UE's mobility level as no / low mobility or full mobility according to the subscription information and / or type of the UE.

[0073] Wherein, the type of the UE is, for example, an Internet of Vehicles device, a smart phone, a smart device with a sensing component, and the like.

[0074] The manner in which the CS control plane main body obtains the subscription information and / or type of the UE is, for example, through receiving an attach / TAU request message sent by the UE.

[0091] see image 3 As shown, the second embodiment of the present invention provides a location management method, which is applied to the main body of the CS control plane, and includes the following steps 301 to 307, which are described in detail as follows.

[0092] Step 301: Determine the UE's mobility class.

[0093] In the embodiment of the present invention, when the CS control plane main body determines the UE's mobility level, it can determine the UE's mobility level as no / low mobility or full mobility according to the subscription information and / or type of the UE.

[0094] Step 302: According to the mobility level of the UE and the offload capability of the LS, configure the TA of the UE as the service area of ​​the LS user plane or the service area of ​​the LS control plane, and allocate a TA list to the UE.

[0095] In the embodiment of the present invention, after determining the UE's mobility class, the CS control plane body can combine the UE's mobility class...

example 1

[0108] Corresponding to non-mobility UEs, the TA of such UEs is the service area of ​​the LS user plane. Since such UEs will not be removed from the configured TA list, only the TAU process initiated due to periodicity or other trigger conditions should be considered.

[0109] see Figure 4 As shown, the TAU process of the non-mobility UE includes the following steps:

[0110] Step 401: Due to the expiration of the periodic update timer (or other trigger conditions), the UE decides to trigger the TAU process and sends a TAU request message to the AN; the information carried in the TAU request message includes the ID of the UE;

[0111] Step 402: AN routes the TAU request message to the correct CS control plane subject (corresponding to the MM function) based on the radio resource control RRC information; the information carried in the TAU request message includes the ID of the corresponding base station;

[0112] Step 403: The CS control plane main body resets the periodic u...

Abstract

The invention provides a position management method and device, wherein the position management method comprises the steps of: determining the mobile level of UE, configuring the TA of the UE as a service area of an LS user plane or a service area of an LS control plane according to the mobile level of the UE and the distribution capability of an LS, furthermore, distributing a TA list to the UE,and sending the TA list to the UE, so that the UE configures the TA list. According to the scheme in the invention, on the basis of the mobile level of the UE, the TA is divided; the position management method and device are suitable for a scene after an MM function and an SM function are separated in a 5G network; the UE can be easily identified and tracked effectively; therefore, the mobility ofthe UE can be kept; furthermore, the signalling overhead can be reduced; and the stability of a communication system can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a location management method and device. Background technique [0002] For the fifth generation (5Generation, 5G for short) mobile communication system, it usually supports separation of control and forwarding of the gateway, separation of mobility management (Mobility Management, MM) function and session management (Session Management, SM) function. [0003] According to the description of 3GPP TR 22.891, 5G networks need to provide mobility support for different needs in different scenarios. For example, during high-speed mobility of a terminal (User Equipment, referred to as UE), the network needs to provide high-speed mobility support, while other UEs in a nomadic or static state need the network to support nomadic or static access to the network. According to the description of 3GPP TR22.861, the 5G network mobility architecture provides on-demand mobility su...
