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, characterized in that:

ceasing to send unicast packets to an access terminal;

determining if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein MAC is medium access control and UATI is unicast access terminal identifier; and

transitioning to a BindUATI state.

2. A computer readable medium including instructions stored thereon, characterized in that:

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 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, characterized in that:

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

means for determining if a ReverseTrafficChannelMAC.UATIReceived indication is received, wherein MAC is medium access control and UATI is unicast access terminal identifier; and

means for transitioning to a BindUATI state.
