Embodiment 3

[0135] image 3 It is an interaction diagram of the location update processing method provided by Embodiment 3 of the present invention, as shown in image 3 As shown, this embodiment takes UE joint registration to the EPC network PS domain and 2G / 3G network CS domain as an example, and the mobility management network element in the EPC network PS domain is MME, but this embodiment is also applicable to UE joint registration to support Gs Interface 2G / 3G network. The difference is that the mobile management network element of the PS domain of the 2G / 3G network is the SGSN. This embodiment is a specific example, and is not intended to limit the protection scope of the present invention.

Embodiment 5

[0171] An embodiment of the present invention provides a mobility management network element, which may be one of the execution subjects of the above method embodiment, and the specific process may refer to the above method embodiment, and details are not described here. Such as Figure 5 As shown, the mobility management network element includes: a receiving module 501 and a sending module 502 . Wherein, the receiving module 501 is used to receive the location update request sent by the user equipment UE; the sending module 502 is used to send indication information to the UE if the MSC / VLR registered by the UE is unreliable, and the indication information is used to indicate the The UE initiates a registration process to the circuit-switched CS domain according to the indication information.

[0172]The location update request received by the receiving module 501 may be a joint location update request, or a periodic location update request. The UE has successfully achieved...

Abstract

Provided are a method and device for processing location update. The method comprises: a mobile management network element receives a location update request sent by a user equipment (UE); and if a mobile switching centre / visitor location register (MSC / VLR) registered by the UE is unreliable, the mobile management network element sends instruction information to the UE, wherein the instruction information is used to instruct the UE to initiate a registration process to a circuit switching (CS) domain according to the instruction information. A device may be a mobile management network element and a user equipment. The mobile management network element comprises a receiving module and a sending module. The user equipment comprises a sending module, a receiving module and a first update module. The solution provided in the present invention effectively realizes quick re-registration of a UE to a CS domain, and avoids a time delay and an unnecessary signalling load of a subsequent uplink and downlink CS service.

Description

technical field [0001] The present invention relates to communication technology, in particular to a location update processing method and equipment. Background technique [0002] Evolved Packet System (EPS for short) is the third generation partnership project (3rd Generation Partnership Project, 3GPP for short) in the second generation (The Second Generation, 2G for short) mobile communication network Global System of Mobile communication (Global System of Mobile) Communication (GSM for short) / Enhanced Data Rate for GSM Evolution (EDGE for short) and 3G mobile communication network Universal Mobile Telecommunications System (UMTS for short). The EPS network includes Evolved Universal Mobile Telecommunications System Territorial Radio Access Network (Evolved Universal Mobile Telecommunications System Territorial Radio Access Network, E-UTRAN for short) and Evolved Packet Core Network (Evolved Packet Core Network, EPC for short). Based on the interface function named SGs be...
