Problems solved by technology

According to the current paging processing mechanism, when the UE performs the called service, the MSC sends paging messages to all access network elements under the LA according to the LA where the UE is located, not just the access network elements that support the wireless access technology currently used by the UE. Paging messages will be generated when entering the network, and paging messages will also be generated on other standard access networks, and the processing of paging messages by other access networks is meaningless, and the UE will definitely not be paged, and these messages will only Increase the load of the access network and occupy the wireless resources of the access network

Embodiment 1

[0023] In this implementation example, a mobile network in which a GSM access network and a WCDMA access network are mixed networks is taken as an example to illustrate the paging process in the mobile communication system. access network. figure 1 Shown is the specific paging process, including the following steps:

[0024] In step 101, the UE searches for an access network that can be camped on when powered on, and initiates a location update request to the core network through the access network;

[0025] In this step, the location update request may be a location area update request or a routing area update request. In this embodiment, the access network where the UE resides is a GSM access network, and the UE initiates a location update request to the core network MSC through the GSM access network. An area update request, in other embodiments, the UE may also initiate a routing area update request to the core network (such as SGSN) through the access network.

[0026] ...

Embodiment 2

[0033] This embodiment is aimed at the situation that the type of radio access technology adopted by the UE itself changes, and describes the implementation process of the technical solution of the present invention. At this time, when the UE determines that the type of radio access technology adopted by itself has changed, it The subsequent access network initiates a location update request to the CN, wherein the location update request includes a location area update request and a routing area update request, and then, during the interaction process between the CN and the UE, the CN performs steps 102 to 104 in Embodiment 1 The corresponding operation can be.

[0034] In other embodiments, when the aforementioned UE is a multi-mode terminal, the types of access RATs currently used by it may also be multiple.

Abstract

The invention discloses a paging method in a mobile communication system, relating to a mobile communication system. The method of the invention is applicable to a mixed network containing a plurality of standard mobile access networks, comprising the following steps: in the process of starting position updating by user equipment through the access network, a core network stores position information of the user equipment and the wireless access technique type of the access network; after receiving the service request in which the target device is the user equipment, the core network reads the prestored position information of user equipment and the wireless access technique type, and sends paging information to the access networks in support of the wireless access technique type in the position region indicated by the position information; and the access network receiving the paging information pages the user equipment. The technical scheme of the invention effectively saves bandwidth resources and processing load of the mobile network under the premise that the called service of UE is not influenced.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a paging method in the mobile communication system. Background technique [0002] When the called service of the user equipment (User Equipment: UE) is established in the mobile network, the mobile switching center (Mobile Switch Centre: MSC) decides to place a call to the LA according to the locally recorded location area (Location Area: LA) information of the UE. All access networks send paging messages, and UE receives the paging messages to process the called service. [0003] The current mobile communication system is in the second generation (2 nd Generation: 2G) to the third generation (3 rd Generation: 3G) During the evolution process, the 3G system will evolve to other mobile communication systems in the future. The difference between mobile communication systems of different standards mainly lies in that the wireless access technologies adopted by the access network ...
