The invention discloses a roaming method. The roaming method includes steps: a roaming server receives an authentication information request instruction sent by a mobile terminal in a roaming network, wherein the authentication information request instruction includes current position information of the mobile terminal; a preset authentication terminal associated with the position information is selected according to the authentication information request instruction, a control instruction is sent to the selected preset authentication terminal, the preset authentication terminal registers at the current network which the preset authentication terminal is located in according to the control instruction, obtains authentication information, and feeds back the obtained authentication information to the roaming server; and the authentication information is forwarded to the mobile terminal, and the mobile terminal registers at the current network which the preset authentication terminal is located in according to the authentication information and uses the network. The invention also discloses a roaming server, a mobile terminal and a system. According to the roaming method, the roaming server, the mobile terminal and the system, the communication cost is greatly reduced, any improvement of hardware of the mobile terminal is not needed, and simplicity and convenience are achieved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a roaming method, a roaming server, a mobile terminal and a system. Background technique [0002] At present, with the improvement of people's living standards, more and more people go abroad for tourism and business work. However, due to the high cost of international roaming, when people carry terminals abroad, if they use domestic mobile phone numbers, the communication cost will be very high. , if you apply for a local mobile phone card abroad, the process is more troublesome, and generally traveling abroad is short-term, and it is not cost-effective to apply for a new mobile phone card. Roaming methods for communication costs. [0003] Existing roaming methods mainly include the following two types: 1. Realize by using a virtual SIM card. The terminal uses the virtual SIM card to use the service provided by the roaming network operator for service transmissio...
