Embodiment Construction

[0035] The embodiment of the present invention is derived from the mode of switching from the LTE access network to the GSM / UMTS network, but is not limited to this switching mode, for example, it can also be switched from the CDMA 2000 1X access network to the CDMA 2000 1x-EV DO access network, or handover from a GSM / UMTS network to an LTE access network, etc., that is, the embodiments of the present invention are applicable to location area update in the process of handover from various source networks to target networks.

[0036] The location area update method in the network handover of the embodiment of the present invention includes the following steps:

[0037] 1. The UE receives the location area list sent by the source network cell, where the location area list includes at least one location area of ​​the target network corresponding to the source network cell;

[0038] 2. After the UE is handed over to the target network, register the UE in the location area of ​​the...

Abstract

The present invention discloses a method for updating location area in network switching, wherein the method comprises the following steps: receiving the location area list which is transmitted by a source network cell by the customer equipment, the location area list comprises a least one location area of target network corresponding with the source network cell; after the customer equipment is switched to the target network, registering the customer equipment to the location area of actually positioned target network; and when the location area registered by the customer equipment belongs to the location area list, retaining the location area registered by the customer equipment. The invention can effectively prevent the unnecessary location area updating in prior plan and saves the signaling expenditure of system. The invention also provides a device for updating location area in network switching correspondingly with the method.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a location area update method and device in network switching. Background technique [0002] Due to the huge amount of network element data in the IP Multimedia System (IP Media System, IMS), it is very difficult to construct, and the IMS standard is not perfect yet. Therefore, the 3rd Generation Partner Project (3rd Generation Partner Project, 3GPP) It will take time for the system architecture evolution (System Architecture Evolution, SAE) project to fully replace the circuit (Circuit Service, CS) domain with IMS. Adopt the LTE application scheme of IMS as transition. [0003] Among the many LTE transition solutions that do not use IMS, there is an LTE fallback to CS (LTE Fallback to CS) solution that is currently concerned by the standard. This solution has the following characteristics: ①LTE is only responsible for high-speed data access and does not support Vo...
