Abstract

A method and apparatus for managing assignment during handoff in a wireless communication system is described. It is determined if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol. The forward link access terminal assignments (FL-ATAs) associated with the FLSS is cleared.

Claims

1. A method of managing assignment during handoff in a wireless communication system, characterized in that:

determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

clearing forward link access terminal assignments (FL-ATAs) associated with the FLSS.

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

a first set of instructions for determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

a second set of instructions for clearing forward link access terminal assignments (FL-ATAs) associated with the old FLSS.

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

means for determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

means for clearing forward link access terminal assignments (FL-ATAs) associated with the FLSS.

4. A method of managing assignment during handoff in a wireless communication system, characterized in that:

determining if a forward link assignment block (FLAB)/non sticky forward link assignment block (NS-FLAB) comprising an access terminal'"'"'s MACID and a supplement field set to ‘

0’

is received from a dedicated forward shared signaling (DFLSS);

issuing a ChangeFLSS command to change from a forward link shared signaling (FLSS) to a DFLSS;

ignoring the FLABs or NS-FLABs coming from sectors other than the current FLSS or DFLSS;

determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

clearing forward link access terminal assignments (FL-ATAs) associated with the old FLSS and updating the appropriate FL-ATA/FL-NS-ATA according to the new FLAB/NS-FLAB.

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

a first set of instructions for determining if a forward link assignment block (FLAB)/non sticky forward link assignment block (NS-FLAB) comprising an access terminal'"'"'s MACID and a supplement field set to ‘

0’

is received from a dedicated forward shared signaling (DFLSS);

a second set of instructions for issuing a ChangeFLSS command to change from a forward link shared signaling (FLSS) to a DFLSS;

a third set of instructions for ignoring the FLABs or NS-FLABs coming from sectors other than the current FLSS or DFLSS;

a fourth set of instructions for determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

a fifth set of instructions for clearing forward link access terminal assignments (FL-ATAs) associated with the old FLSS and updating the appropriate FL-ATA/FL-NS-ATA according to the new FLAB/NS-FLAB.

6. An apparatus operable in a wireless communication system, characterized in that:

means for determining if a forward link assignment block (FLAB)/non sticky forward link assignment block (NS-FLAB) comprising an access terminal'"'"'s MACID and a supplement field set to ‘

0’

is received from a dedicated forward shared signaling (DFLSS);

means for issuing a ChangeFLSS command to change from a forward link shared signaling (FLSS) to a DFLSS;

means for ignoring the FLABs or NS-FLABs coming from sectors other than the current FLSS or DFLSS;

means for determining if a forward link shared signaling (FLSS) Changed Indication is received from a RCC MAC protocol; and

means for clearing forward link access terminal assignments (FL-ATAs) associated with the old FLSS and updating the appropriate FL-ATA/FL-NS-ATA according to the new FLAB/NS-FLAB.
