Network search and configuring method, registratio method, device and system

A network search and registration method, being performed on a communication terminal, comprising following steps of:

• obtaining location information of a current location of the communication terminal;
• sending, by the communication terminal, a service request carrying location information to a server in order that the server dynamically configures various parameters in the SIM card to be registered according to the location information;
• receiving, by the communication terminal, the SIM card to be registered having the various dynamically configured parameters from the server;
• and
• searching and registering network for the SIM card to be registered accordingly by the communication terminal according to the various configured parameters.

A network search, configuration and registration system, comprising:

• a communication terminal and a server being in communication with the communication terminal;
• wherein the server is configured to:
• receive a service request carrying location information sent by the communication terminal;
• obtain various optimal parameters in a SIM card to be registered corresponding to the location information according to the service request;
• dynamically configure the various parameters in the SIM card to be registered according to various optimal parameters;
• and
• send the dynamically configured SIM card to be registered to the communication terminal;
• the communication terminal is configured to:
• receive the SIM card to be registered which includes the various dynamically configured parameters from the server;
• and
• search and register network for the SIM card to be registered accordingly according to the various dynamically configured parameters.
