PURPOSE: A trunk allocation message control apparatus and method using a V5.2 BCC protocol in a WLL system are provided to effectively perform maintenance and management of a trunk allocation message by checking whether a trunk allocation response message has been received from a subscriber unit and sequentially transmitting it, and stabilize a WLL system by preventing loss of the trunk allocation message. CONSTITUTION: A call processor(1100) mounted in a WLL exchanger(1000) outputs a call process control signal to a BCC protocol processor(1200) when a call is attempted from an external source. The BCC protocol processor(1200) mounted in the WLL exchanger(1000) receives the call process control signal from the call processor(1100), generates a trunk allocation message and outputs it to a level 2 protocol processor(1300). When the BCC protocol processor(1200) receives a trunk allocation response message from the level 2 protocol processor(1300), it allocates a trunk to perform a call processing. The BCC protocol processor(1200) includes a memory(1210) and a BCC V5.2 entity(1220). The memory(1210) mounted in the BCC protocol processor(1200) includes a trunk allocation message storing table(1211), a non-use queue managing table and a BBC queue managing table(1213), and stores the trunk allocation message generated by the BCC V5.2 entity(1220) if the BCC protocol is in a standby state for transmission. |
