METHOD FOR DUPLEXING ACCESS TERMINAL INFORMATION OF OHM IN EVDO CONTROL STATION SYSTEM, PARTICULARLY FOR MAKING TERMINAL CALL INFORMATION OF ACTIVE AND STANDBY OHMS IDENTICAL IN IMPLEMENTING DUPLEXING, AND RE-STARTING THE STANDBY OHM BY RECEIVING TERMINAL CALL INFORMATION OF THE ACTIVE OHM

摘要

PURPOSE: A method for duplexing access terminal information of an OHM(OverHead Manager) in an EVDO(Evolution Data Only) control station system is provided to guarantee continuity of an EVDO service in occurrence of a failure of a system by making a standby OHM provide the service when an active OHM is failed. CONSTITUTION: An active OHM(300) receives a UATI(Unicast Access Terminal Id) request message from an AT(Access Terminal)(100) and assigns a UATI. An SF(Selector Function) block(400) for processing a radio protocol and routing a packet is selected. An RSM(RLP and Signaling Manager) assignment request message is transmitted to the selected SF block(400). When a response message to the request message is received from the SF block(400), the UATI request message which has been received from the AT(100) and the allocated UATI information are transmitted to the SF block(400). The SF block(400) transmits the UATI assignment message to the AT(100). The AT(100) transmits a UATI completion message informing that UATI assignment has been normally made to the active OHM(300).
