PROCEDURE AND AMENDMENT OF THE SUMMARY OF CONTRIBUTION IN A SUMMARY TRANSFER SYSTEM AND SUMMARY OF SUMMARY TRANSFER SYSTEM

摘要

The present invention provides a method for changing communication in a communication system (100). The communication system (100) includes a base station subsystem (102) and a mobile switching center (120). The base station subsystem (102) includes a first transcoder (108) and a second transcoder (109) connected to the mobile switching center (120), a first base station controller (106) connected to a first transcoder (108), a second base station controller (107) connected to a second transcoder (109), and a base transceiver station (104) connected to the first base station controller (106) and the second base station controller (107). A communication is established between a mobile station and the mobile switching center (120). The communication travels to the mobile switching center (120) via a first link (110) that includes the first base station controller (106). If the first link (110) is no longer the preferred link, the communication is changed to a second link (112) that includes the second base station controller (107).
