METHOD FOR TRANSFORMING SERVICE OPTION INTO CIRCUIT DATA

摘要

A method for transforming service option into circuit data includes the following steps, first step: a mobile station notifies a source base station and/or a target base station to transform service option into circuit data during a session; second step: the source base station and/or the target base station negotiates with a mobile switch subsystem about transforming service option into circuit data, and determines the session's bearer format parameters through the negotiation; third step: the source base station and/or the target base station makes a secondary negotiation with the mobile station after the negotiation with the mobile switchsubsystem is succeeded; and fourth step: after the negotiation with the mobile station is succeeded, the source base station and/or the target base station encapsulates circuit data into user interface service layer according to certain load format, and then transmits the encapsulated Real Time Transfer Protocol packets to the other base station.
