Abstract:
1. A method of sharing resource in a data communication system, the system including a first centralized network (FCN), a second centralized network (SCN), and a gateway, the FCN including a first central coordinator (CC 0 ) managing the activities of the FCN and the gateway, and the SCN including a second CC 0 managing the activities of the SCN and the gateway, the method comprising steps of: requesting, by the gateway, resource allocation from the first CCO; determining, by the first CCO, availability of at least one first CCO contention-free-period (CFP) time slot; if the at least one first CCO CFP time slot is available: allocating to the gateway, by the first CCO, the at least one first CCO CFP time slot; and transmitting by the first CCO allocation information to the gateway related to the allocated at least one first CCO CFP time slot; and if the at least one first CCO CFP time slot is unavailable: transmitting by the first CCO allocation unavailability information to the gateway; requesting, by the gateway, resource allocation from the second CCO; determining, by the second CCO, availability of at least one second CCO CFP time slot; if the at least one second CCO CFP time slot is available: allocating to the gateway, by the second CCO, the at least one second CCO CFP time slot; and transmitting by the second CCO allocation information to the gateway related to the allocated at least one second CCO CFP time slot; and if the at least one second COO CFP time slot is unavailable: transmitting, by the second CCO, allocation unavailability information to the gateway; and performing a neighbor network coordination protocol to obtain additional resource for the gateway.
