One-card multi-number service system and communication method

Abstract

The invention discloses a one-card multi-number service system supporting dispersed numbers and a communication method and relates to the field of mobile communication. The one-card multi-number service system receives a service request forwarded by a user access network from a user, and the service request is routed according to a virtual IMSI; the virtual IMSI is replaced with a main IMSI or an auxiliary IMSI according to the service request, and a service request process is sent to a corresponding network according to the main IMSI or the auxiliary IMSI; the one-card multi-number service system stores a main number and a main IMSI, an auxiliary number and an auxiliary IMSI, and a virtual IMSI and a virtual MSC identifier corresponding to a mobile phone card of the user; and the route of the main number or the main IMSI points to a first party network, the virtual IMSI is a special continuous number section for the one-card multi-number user and is in one-to-one correspondence with the mobile phone card, the route of the virtual IMSI points to the one-card multi-number service system, and the routes of the auxiliary number and the auxiliary IMSI point to a second party network. Therefore, the user can use an original number, no signaling screening is needed, service deployment is simple, ordinary users are not affected, the system risk is small, and the safety is high.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a one-card-multiple-number service system supporting dispersed numbers and a communication method for the one-card-multiple-number service. Background technique [0002] With the trend of global economic integration becoming more and more obvious, transnational economic trade and non-governmental exchanges are getting closer and closer, a large number of users need to travel between different countries and regions frequently, and the increase of international mutual visiting users is providing the development of communication services. At the same time, it also puts forward new requirements for the long-standing single way of providing international roaming services. Therefore, the industry proposes a one-card multi-number service, which can realize the communication function of two numbers through one mobile phone card, which can prevent users from using special dual-mode or ...

Problems solved by technology

[0012] First of all, the existing one-card multi-number service adopts the method of not changing the mobile phone card but changing the secondary number of the partner. On the one hand, the user of the one-card multi-number needs to replace the new secondary number of the partner, and the user cannot use the original number. Not good; on the other hand, because one-card multiple-number users do not change their mobile phone cards, the IMSI of users who have opened one-card multiple-number service is a discrete number segment for the one-card multiple-number service system, and some services routed according to IMSI The message cannot be directly routed to the one-card multi-number business system, and the signaling swiping function needs to be added. The investment in service deployment is large, and the signaling swiping system will send all the business messages (such as location update messages) from partners routed according to ISMI. After the one-card-multiple-number service system is screened, the business system further judges that the user is an ordinary international roaming user or a one-card multiple-number user. Therefore, any failure of the signaling screening system or the one-card multiple-number service system will affect the cooperation of the partner. All businesses have high system risk and low security

[0013] Secondly, the secondary number segment is provided and managed by the one-card multi-number service system. The service system needs to undertake the functions such as HLR / MSC / MC corresponding to the secondary number. Taking the MC function as an example, the service system needs to provide information such as SMS content storage and sending status. Storage, SMS resending and other functions of the called SMS center, therefore, the implementation of the business system is complex
