Problems solved by technology
[0005] In the prior art, there is no specific implementation plan for visiting one-card-multiple-number services. When the terminal roams to the visited network, it still needs to use the home phone number to make calls or send and receive short messages. Since roaming costs are relatively expensive, therefore Increased user spending

Embodiment Construction
[0025] In the embodiment of the present invention, the service server (in the embodiment of the present invention, the service server is referred to as ISG, International Service Gateway) obtains the signaling transmitted between the home network and the visited network of the terminal that has signed a one-card-multiple-number service ; performing number conversion on the telephone number of the terminal according to the signaling, so that the terminal uses the converted telephone number for communication. Wherein, the operation of the ISG to acquire the signaling transmitted between the home network and the visited network of the terminal that subscribed to the one-card-multi-number service may specifically include: monitoring the VLR (Visitor Location Register) of the terminal to the terminal The location update message sent by the HLR (Home Location Register, user's home location register), and the user data message sent by the HLR to the VLR, obtain network information fro...

The invention discloses a method for realizing the service of one card with multiple numbers, particularly comprising the following steps: a signaling transmitted between a terminal attribution network which signs a contract for the service of one card with multiple numbers and a visited network is acquired by a service server; number transformation is carried out on the telephone numbers of a terminal according to the signaling so as to ensure the terminal to use the transformed telephone numbers to carry out communication. The embodiment of the invention also provides a system and a serviceserver for realizing the service of one card with multiple numbers. The signaling sent by a network side is monitored by an added service server, and number transformation is carried out on the telephone numbers of the terminal to realize the service of one card with multiple numbers of the terminal, thus telephone expenses of users are reduced.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, system and device for realizing one-card-multiple-number service. Background technique [0002] The one-card-multiple-number service is a service in which the original SIM card is used to provide the original number and the local number of the roaming place without changing or adding a SIM (Subscriber Identity Model, customer identification module) card or mobile phone when the user is roaming. [0003] The outbound one-card multi-number service is provided by the home operator. The user pre-registers with the home operator for a roaming number, which is provided by an operator in the roaming area that has a cooperative relationship with the home operator. , the user can use the one-card-multiple-number service while roaming. [0004] In the process of realizing the present invention, the inventor found that at least the following problems existed in the p...
