PURPOSE: A call transfer method in a mobile telecommunication system is provided to achieve a call between a calling subscriber and a new called subscriber called by a called subscriber as a mobile call transfer part in a mobile subscriber control subsystem works together with a mobile subscriber control part, an extrinsic service control part, etc. CONSTITUTION: A mobile subscriber control subsystem consists of a mobile call transfer part(10), a fixed subscriber control part(11), a mobile subscriber control part(12), an R2 transit call control part(13), a No.7 transit call control part(14), a message conversion processing part(15), an extrinsic service control part(16), and a library configuration part(17). The mobile call transfer part(10) works together with each control part in order to transfer a mobile call. The fixed subscriber control part(11) is worked together with the mobile call transfer part(10) in case that origination or call transfer termination is by a fixed subscriber. The mobile subscriber control part(12) is worked together with the mobile call transfer part(10) in case that origination or call transfer termination is by a mobile subscriber. The R2 transit call control part(13) is worked together with the mobile call transfer part(10) in case that a call by origination or call transfer is an R2 transit call. The No.7 transit call control part(14) is worked together with the mobile call transfer part(10) in case that a call by origination or call transfer is a No.7 transit call. The message conversion processing part(15) is worked together with the mobile call transfer part(10) in the case of transmitting a message to a base station controller or receiving a message from the base station controller. The extrinsic service control part(16) makes the mobile call transfer part(10) operated differently from other extrinsic services when the call transfer service is attempted. The library configuration part(17) is composed of libraries that software process blocks use in common.
