Method for implementing intelligent service at roaming access mode and gateway mobile exchange centre

Abstract

This invention provides a method for realizing intelligent service in the local gateway mobile switch center at roam access mode including: judging if a calling number of calls entering from outside gate mobile switch center is the local network number section, if it is the local one, then it enquires if the calling number includes intelligent service to a HLR attributed to the user and picks up intelligent signed information if so, then plugs the picked up user intelligent signed informatiom into an accessed location register, then triggers the intelligent service based on the signed information stored in the location register then to process the traditional called flow.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing intelligent services in a gateway mobile switching center of a calling user in a roaming access mode and the related gateway mobile switching center. Background technique [0002] Roaming between mobile networks can adopt the traditional international roaming mode or the "roaming access" mode. In roaming access mode, a mobile subscriber roams to a home network other than the mobile subscriber's registered home network (see figure 1 The different network of label 2) in (namely figure 1 In the external network 1) in , the foreign network is operated by another operator different from the home network operator registered by the mobile user. In this case, the mobile user initiates a call, and after the mobile switching center (MSC) of the external network 1 finds that it is not a call sent by the user of the external network 1, it does not process it, bu...

Also take the above-mentioned example as an example, after the call in the above-mentioned example returns to the Gateway Mobile Switching Center (GMSC) (21), if the calling user has registered an intelligent service, as the calling user is a prepaid user (prepaid is a For intelligent services, for prepayment, the user's intelligent subscription information must be retrieved from the home HLR, placed in the VLR, and then the intelligent network is triggered accordingly, and the intelligent network deducts the fee first, and then the call can be received by the called user), and The Gateway Mobile Switching Center (GMSC) (21) does not have a VLR, and the intelligent network service cannot be triggered by the calling user at the GMSC, so the route selection can only be carried out completely according to the called number, and the user cannot be deducted in advance. Can only carry out post-paid services, but cannot carry out pre-paid services and other smart services

[0004] Therefore, the traditional GMSC can no longer adapt to the development of the current access roaming mode, and a new type of GMSC that can overcome the prejudice of the traditional GMSC and can provide intelligent services for the calling user is needed. The Method of Realizing Intelligent Service in Network GMSC
