Patent ID: 6859458

Claim:
A multiple access control system with intelligent bandwidth allocation for wireless ATM networks which transfer information via frames, each frame being divided into a plurality of slots to be allocated to constant bit rate (CBR), variable bit rate (VBR), available bit rate (ABR), and signaling control (SCR) traffic classes, the frame having a common notification field (CNF) slot for being placed with code sequences by mobile terminals using ABR slots, the system comprising: an intelligent bandwidth allocator for allocating reservation type bandwidth to the mobile terminal when the mobile terminal requests a CBR/VBR traffic, and dynamically allocating contention type bandwidth to the mobile terminal when the mobile terminal requests SCR and ABR traffics; a traffic estimator/predicator for predicting the CNF value of a subsequent frame by the CNF value of at least one frame, and determining the number of the SCR slots and ABR slots to be allocated by the intelligent bandwidth allocator based on an optimal allocation model for the contention type bandwidth constructed in offline; and a multiple access controller for providing the reservation type bandwidth with a multiple access function in a reservation access manner, and providing the contention type bandwidth with a multiple access function in a contention access manner.
