Abstract

The invention discloses a mobile communication method based on an SIM (Subscriber Identity Module) card. The method comprises the following steps that: a terminal requests to register with a network by adopting the default account information of a standard SIM card portion; a control module sends a command requesting an auxiliary number to a support module; the support module allocates one auxiliary account after receiving the command requesting the auxiliary account, and returns auxiliary account information to the control module; and the control module sets the auxiliary account information as a new default account. Moreover, the invention further discloses a server side and a terminal for running the method. Through adoption of the mobile communication method based on the SIM card and equipment for running the method provided by the invention, roaming charges can be effectively reduced. The mobile communication method and the equipment have the characteristics of low network transformation cost and low user use cost.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and equipment for realizing mobile communication roaming in a mobile communication network. Background technique [0002] Usually, after a mobile user subscribes to the international roaming service and roams to another country's network, he can continue to use his home country number (MSISDN) for mobile communication services such as calls, SMS messages, and data services. However, because international roaming involves cooperation, sharing and settlement between the mobile number's home operator and the roaming operator, the cost is very expensive. [0003] In the prior art, several technologies have played a role in reducing roaming charges. First, the USSD call-back service is adopted, and the main process is as follows: When user A needs to call user B, the user inputs a series of USSD strings, carrying the called number in the USSD strings, and the USSD strings...
