Abstract

A method and apparatus for reducing power consumption in a wireless communication system is described. Sending of unicast packets to an access terminal is ceased. It is determined if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein MAC is medium access control and UATI is unicast access terminal identifier. The access network transitions to a BindUATI state.

Claims

1. A method of reducing power consumption in a wireless communication system, comprising:

ceasing to send unicast packets to an access terminal;

determining if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein an affirmative determination indicates that an access network received a ReverseTrafficChannelMAC.UATI signal, and wherein MAC is medium access control and UATI is unicast access terminal identifier; and

transitioning to a BindUATI state.

2. A computer-readable, non-transitory storage medium storing instructions, the instructions comprising:

a first set of instructions for ceasing to send unicast packets to an access terminal;

a second set of instructions for determining if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein an affirmative determination indicates that an access network received a Reverse TrafficChannelMAC.UATI signal, and wherein MAC is medium access control and UATI is unicast access terminal identifier; and

a third set of instructions for transitioning to a BindUATI state.

3. An apparatus operable in a wireless communication system, comprising:

means for ceasing to send unicast packets to an access terminal;

means for determining if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein an affirmative determination indicates that an access network received a ReverseTrafficChannelMAC.UATI signal, and wherein MAC is medium access control and UATI is unicast access terminal identifier; and

means for transitiioning to a BindUATI state.
