Abstract:
A method for managing trunk status of a CDMA mobile communication exchange, the method comprising steps of:a number translation block in a number translation processor requesting a local routing control block of a first trunk access switching subsystem, the control block being selected based upon route number for managing determined route information, to conduct routing; said requested local routing control block locating available logical trunk number from trunk groups constituting routes and then registering the busy status therefor; said local routing control block selecting a second trunk access switching subsystem in which physical trunk number assigned to said logical trunk number and trunk number are provided; said local routing control block requesting an R2 signaling trunk control block in the selected second trunk access switching subsystem to occupy the trunk; the requested R2 signaling trunk control block requesting a telephony device system library in the second trunk switching subsystem to which said R2 signaling trunk control block pertains, to register the busy status of the trunk; if the requested trunk status is in idle status, conducting the registration of the busy status for the associated trunk and then notifying the R2 signaling trunk control block of completion of the busy status registration; said R2 signaling trunk control block notifying the local routing control block in the first trunk access switching subsystem of occupancy success; and said notified routing control block confirming whether the trunk number requested to be occupied is identical with the successful trunk number or not.
