Embodiment Construction

[0015] The specific implementation manner of the present invention will be illustrated below with reference to the accompanying drawings.

[0016] In the present invention, when a user assigns mobile numbers in multiple contracted areas to the user according to the user's subscription status, corresponding to multiple SIM cards, in the present invention, the mobile user is called a multi-card user.

[0017] When a multi-card user allocates a number, the cross-domain networking HLR assigns the user a unique UserID (User Identify) in the entire network, and the HLR in each region records the UserID, and records the associated HLR address of the multi-card user in other regions. In this way, through the UserID, the data of multi-card users distributed in the networked HLR in various places are logically associated together.

[0018] Multi-SIM users have signed contracts with local data in multiple regional HLRs. Physically, these HLRs are independent of each other, but they are c...

Abstract

This invention discloses a method for a mobile user panning in cross-domain. A mobile user signs agreements with multiple mobile communication areas of many corresponding SIM cards including the following steps: a mobile user is assigned to have an exclusive User ID, HLR at each contracted zone registers the said User ID and related HLR addresses of other contracted zones, after successing altering positions with altered SIM cards, the local HLR informs the excited IMSI user certification to HLR of other contracted areas by self defined signaling according to User ID, related HLR addresses.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to cross-regional roaming of mobile users. Background technique [0002] When a mobile user opens an account, the operator assigns a user identifier IMSI (International Mobile Subscriber Identity International Mobile Subscriber Identity Code) to the user, and the SIM (Subscriber Identity Module) card stores IMSI, encryption and other data, and then in the HLR (HomeLocation Open an account for the user in the Register user's home location register), that is, record all relevant data such as the user's IMSI, mobile number, and subscription service in the HLR. In the existing mobile network, the data stored in the HLR is generally only in the local area, that is, the IMSI and the mobile number are in the local area. [0003] With the global economic integration, the connection and communication between different regions in the world are constantly strengthening. Mobile communicatio...
