Problems solved by technology

[0004] Therefore if the user chooses an operator that does not provide roaming services, when the user arrives in other places, he can only choose to open an account again on the local network. Since a card in the prior art can only correspond to one number, the user also needs to buy a mobile phone card again, which is very difficult. Inconvenient; if the user chooses an operator that can provide roaming services, the roaming charges incurred by the user communication will be high

Embodiment Construction

[0024] The invention provides a method and system for realizing one card with multiple numbers. Since the method for realizing one-card-multiple-number is realized based on the home location register, the one-card-multiple-number realized by the present invention is abbreviated as MSNH (Multiple Subscriber Number Based on HLR) in the following description.

[0025] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0026] Please refer to FIG. 1 , which is a structural diagram of a preferred embodiment of a system for realizing one card with multiple numbers according to the present invention. The system for implementing one card with multiple numbers includes a main home location register (HLR, Home Location Register) 10, a secondary HLR 20 and a user terminal 30, and the system for realizing one card with multiple numbers may inclu...

Abstract

This invention provides one method and system to realize one card with multiple numbers, which comprises the following steps: user card gets main number at main position belong register opening and gets relative aid number at aid position belong register open; the said aid device records opened aid number and main position label; in user initiating communication to send position register require to main position register; processing communication number to judge whether to open user terminal according to position requirement.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a technology for realizing one card with multiple numbers. Background technique [0002] Many existing Code Division Multiple Access (CDMA, Code Division Multiple Access) digital wireless communication technology networks are wireless local loop (WLL, Wireless Local Loop) networks. As a WLL network, users are restricted to a certain area and cannot roam. When the user communicates in the home network environment, it does not belong to roaming; when the user leaves the home area and roams to another network environment, communication cannot be performed. [0003] Even if roaming is allowed, because the network resources from the roaming network to the local network are occupied, the corresponding cost is relatively high. At present, when a user applies for opening an account in the home place, the service system of the local operator is used to register in the home locatio...
