Mobile telephone service request transfer controlling method, involves activating transfer of service request towards global system for mobile communication network as function of specific coded value affecting transfer parameter

摘要

The process involves determining a specific coded value affecting a transfer parameter based on a type of service request. The specific coded value affecting the transfer parameter is transmitted towards an access network controlling execution of the service request. Transfer of the request towards a global system for mobile communication (GSM) network is activated as a function of the specific coded value. The type of service request is dynamically determined based on discrimination criterion of the service with respect to universal mobile telecommunication system (UMTS) and global system for mobile communication (GSM). An independent claim is also included for a device of controlling the transfer of service request emitted in mobile telephone between a UMTS network and a GSM network.
