Embodiment 1

[0049] In this example, if image 3 As shown, the process of updating the tracking area for any terminal in the terminal group may specifically include the following steps:

[0050] Step 301: When each terminal of the terminal group accesses the network, sign up each terminal as a terminal with group characteristics, assign a group identity (GID, Group Identity) to the terminal group, and designate a terminal of the terminal group as the terminal The group representative terminal of the terminal group, using the terminal identity of the terminal as a group representative terminal identity (GRUEI, Group Representative UE Identity), and storing the GID and GRUEI as the subscription data of each terminal in the HSS;

[0051] For example, the first terminal attached to the network in the terminal group can be designated as the group representative terminal of the terminal group, and the terminal identifier of the terminal can be used as GRUEI; or, it can also be set by the MTC use...

Embodiment 2

[0078] In this example, if Figure 4 As shown, the process of updating the tracking area for any terminal in the terminal group may specifically include the following steps:

[0079] Step 401 is exactly the same as step 301;

[0080] Step 402, when the terminal is powered on and attached to the network, the old MME acquires the subscription data of the terminal from the HSS;

[0081] Step 403: When the terminal triggers the TAU process, it sends a TAU request to the new MME, wherein the TAU request includes the terminal's old terminal identifier (such as a globally unique temporary identifier (GUTI)), the old MME's identifier ( Such as the globally unique MME identifier (GUMMEI)), and the GID of the terminal group to which the terminal belongs;

[0082] Step 404: The new MME receives the TAU request sent by the terminal, and according to the old MME identifier in the TAU request, requests the old MME for the context information of the terminal through a context request messa...

Abstract

The invention discloses a tracking area updating (TAU) method which includes: activating a periodic TAU timer of a terminal when the terminal is not the preassigned group representing terminal of a terminal group; and when the terminal enters an idle state and a mobile accessible timer corresponding to the terminal is due, if a network side detects that a paging processing flag (PPF) of the group representing terminal of the terminal group where the local terminal belongs is not cleaned, resetting and restarting the mobile accessible timer corresponding to the terminal. Correspondingly, the invention further discloses a tracking area updating system which achieves the periodic TAU process of the terminal group, reduces information interaction required by finishing the periodic TAU process between terminals of the terminal group and the network side, accordingly saves signaling resources and improves the efficiency for performing periodic TAU of the terminal group.

Description

technical field [0001] The present invention relates to Machine Type Communication (MTC, Machine Type Communication) technology, in particular to a tracking area update method and system. Background technique [0002] A cellular wireless communication system is mainly composed of a core network (CN, Core Network), an access network (RAN, Radio Access Network) and terminals. The core network is responsible for non-access stratum affairs, such as terminal location update, and is the anchor point of the user plane. The access network includes base stations, or base stations and base station controllers. The access network is responsible for access layer affairs (such as management of wireless resources, etc.). There may be physical or logical connections between base stations according to actual conditions, such as figure 1 The shown cellular wireless communication system includes a core network, a base station 1, a base station 2, a base station 3 and a terminal, wherein the ...
