Problems solved by technology

[0008] An embodiment of the present invention provides a paging method to solve the problem in the prior art that in the network error recovery process, when the MME uses the UE's IMSI to page the UE, it cannot determine which TAs to page the UE The problem

Embodiment Construction

[0023] The main realization principles, specific implementation modes and corresponding beneficial effects that can be achieved of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0024] In the embodiment of the present invention, the combination of GUTI and TAI List included in the GUTI Reallocation Command message or the TAU Accept message can be in the following three ways:

[0025] The first combination method: OLD GUTI and NEW TAI List, that is, the MME only allocates the NEW TAI List to the UE, and does not allocate NEW GUTI to the UE;

[0026] The second combination method: NEW GUTI, that is, MME only allocates NEW GUTI to UE, and does not allocate NEW TAI List to UE;

[0027] The third combination mode: NEW GUTI and NEW TAI List, that is, the MME allocates the NEW GUTI and the NEW TAI List to the UE at the same time.

[0028] like figure 1 As shown, it is a flow char...

Abstract

The invention discloses a paging method and a paging device. In the technical scheme, an IMSI (international mobile subscriber identity) of UE (unified equipment) is determined and used for paging the UE, whether a TAI List is stored or not is judged before paging, and the UE is paged in a TA (terminal adapter) served by a connected base station if no TAI List is stored. By the aid of the technical scheme, the problem of incapability of determining which TA needs paging of the UE when the IMSI of the UE is used for paging the UE by an MME (mobility management entity) during network error recovery in the prior art can be effectively solved.

Description

[0001] The application of the present invention is a divisional application of the invention application with the filing date of January 09, 2009, the application number of 200910076582.0, and the invention name of "paging method and device". technical field [0002] The invention relates to the technical field of mobile communication, in particular to a paging method and device. Background technique [0003] In the 3GPP TS24.301 standard specification, it is stipulated that the mobility management entity (MME, Mobility Management Entity) that manages the user equipment (UE, User Equipment) can assign a New Tracking Area Identification List (NEW TAI List, New Tracking Area Identity List) and the UE's Globally Unique Temporary Identity (GUTI, Globally Unique Temporary Identity) are encapsulated in a GUTI Reallocation Command (GUTI Reallocation Command) message and delivered to the UE. If the MME receives the GUTI reallocation command fed back by the UE If a Lower Layer Failur...
