Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0025] The "method for roaming among heterogeneous networks" provided by the present invention is to meet the requirement of users to roam among heterogeneous networks by using the same MSISDN number.

[0026] In order to achieve the purpose of the above invention, the method for roaming between heterogeneous networks of the present invention includes the following steps:

[0027] (A) The location home register stores user information of dual-mode or multi-mode terminal users in various available mobile networks;

[0028] (B) When the end user roams to an available mobile network, the location attribution register updates the mobile network used by the end user before roaming to the roaming mobile network in the location attribution register according to the type of the location update message initiated by the end user;

[0029] (C) The ro...

Abstract

The method comprises: a) the home location register saves the user information about dual-mode terminal user or multi-mode terminal user in each available network; b) when user terminal roams to a available mobile network, according to the type of the location update message initiated by user the home location register updates the mobile network used by use to the mobile network where user is current roaming; c) the roaming network of user makes the next mobile service process according to the user information in the home location register.

Description

technical field [0001] The invention relates to a method for roaming among heterogeneous networks in the field of mobile communication. Background technique [0002] In the field of mobile communication, there are mobile networks of various technical standards, such as GSM, CDMA, 3G and PHS, etc. Users can realize roaming services in the same mobile network. The user data center of the network - the location home register (HLR) stores relevant user data, and after the user roams to a different place, the user can use the corresponding network-wide unique user identifier (IMSI or MSISDN) to perform relevant mobility service management , to obtain the corresponding user information from the user HLR, so as to ensure the realization of the service in the roaming area. [0003] Taking the GSM network as an example, after the user roams to a different place: [0004] First, through the location update business process, use the IMSI saved in the mobile phone by the user as the o...
