METHOD AND APPARATUS FOR DYNAMIC BACKHAUL RESOURCE MANAGEMENT IN A WIRELESS COMMUNICATION SYSTEM

摘要

Various embodiments are described to address the need to lower backhaul costs for EGPRS operators while maintaining the low and constant delay characteristics they require. 20 msec TRAU frames (221-226) are still used for backhaul to maintain the low and constant delay. However, to eliminate the restriction of mapping TRAU timeslots to air timeslots (211-218) one-to-one, the TRAU slots are collectively treated as a one large 20 msec TRAU frame for a group of air timeslots. The data for the air timeslots can be packed efficiently into this giant TRAU frame, ignoring backhaul timeslot boundaries. In this way, the appropriate amount of backhaul for the carrier can be allocated and the data for the air interface timeslots more efficiently packed into the backhaul.
