A method for communication network switching

Abstract

The invention relates to a communication network switching method. The existing communication network switching method needs to replace an SIM (subscriber identity module) card of a user. The communication network switching method comprises the following steps of enabling a service receiving system to receive a service request of a terminal user; forwarding the service request to a remote service management system, enabling the remote service management system to receive the service request, and matching the data and generating a corresponding instruction according to the type of a to-be-switched network, wherein the data comprises one set of personalizing data and an application identifier; sending the instruction to the SIM card corresponding to a first mobile user number; enabling the SIM card to receive the instruction sent by the remote service management system; according to the application identifier in the instruction, writing the personalizing data into a storage directory of the corresponding application in the SIM card; switching the application written with the personalizing data into an effective application. The method has the advantage that the SIM card does not need to be replaced when the communication network is switched.

Description

technical field [0001] The invention belongs to the fields of computer technology, smart cards and telecommunications, and in particular relates to a communication network switching method. Background technique [0002] With the renewal and development of mobile communication network technology and the issuance of domestic virtual operator licenses, the competition among communication operators is becoming fiercer. Providing users with better services is a necessary means for operators to enhance their market competitiveness. For virtual operators, especially for virtual operators with three basic operator licenses at the same time, allowing users to flexibly choose and change the network services they use is an effective means to increase user stickiness. [0003] At present, users are using and replacing mobile terminals more frequently, and different terminals have different requirements for network standards, and the demand for replacing network services is increasing da...

Problems solved by technology

However, under the existing technical conditions, to replace the network service: for example, to change from a WCDMA network to a CDMA2000 network, the user must first go to the business office of China Unicom to cancel the account, and then go to the telecom business office to buy a new SIM card and then open the account. The method is not only cumbersome, but also wastes card resources

[0004] On the other hand, virtual operators currently mainly use the network and standards of basic operators to produce and issue SIM cards, while the SIM cards issued by basic operators have their own standards, network standards, and card file structures. When virtual operators meet users' needs for network replacement, they need to stock different cards and then replace them for users. This not only increases the pressure on stocking, but also incurs a large logistics cost if the online shopping mall provides services.
