Abstract:
1. A method for access procedure enhancement by a wireless communication device comprising a transceiver module for wireless transmissions and receptions, the method comprising: dividing an access channel into a plurality of narrow band frequency division multiplexing channels; grouping a plurality of reverse link frequency division multiplexing access channels into a plurality of reverse link frequency division multiplexing access channel groups; determining whether a base station in a network supports an access probe, and if yes, the base station joins at least one reverse link frequency division multiplexing access channel group; and sending the access probe in the at least one reverse link frequency division multiplexing access channel group during each access procedure, wherein the wireless communication device is a machine to machine communication device, and the method further comprises: the base station maintaining a local table of the reverse link frequency division multiplexing access channel groups and the members thereof, wherein the method further comprises: the base station informing the wireless communication device regarding the reverse link frequency division multiplexing access channel groups which the base station has membership; the base station informing the wireless communication device regarding the reverse link frequency division multiplexing access channel groups each of the neighbors of the base station has membership; and the base station updating the wireless communication device when a change occurs in the group memberships.
