Resource allocation during tune-away
First Claim
1. A resource assignment method during a tune-away procedure, comprising:
- determining a first instance in time that a tune-away will initiate with respect to an access terminal;
determining a second instance in time that corresponds to a latest frame boundary associated with the access terminal prior to the instance in time that the tune-away initiates;
determining resource assignment parameters associated with the access terminal and implementing the resource assignment parameters at the second instance in time;
implicitly expiring an assignment of resources between the access terminal and an access point at the second instance in time; and
explicitly re-assigning base station resources from the access terminal to at least one disparate access terminal beginning at the second instance in time.

Abstract
A resource assignment method during a tune-away procedure comprises determining a first instance in time that a tune-away will initiate with respect to an access terminal, determining a second instance in time that corresponds to a latest frame boundary associated with the access terminal prior to the instance in time that the tune-away initiates, and determining resource assignment parameters associated with the access terminal and implementing the resource assignment parameters at the second instance in time. The method can further comprise ceasing communications to the access terminal over a forward link at the second instance in time and discontinuing monitoring reverse link control channels associated with the access terminal at the second instance in time.

18. A wireless communications apparatus, comprising:
-
a memory that includes a schedule for a tune-away with respect to an access terminal; and a processor that determines a frame boundary that occurs in time immediately prior to a time of commencement of the tune-away and implicitly expires resource assignments for the access terminal at a time that corresponds to the determined frame boundary at an access point associated therewith as a function of content of the schedule, the processor re-assigning resources from the access terminal to at least one disparate access terminal beginning at the time corresponding to the determined frame boundary. - View Dependent Claims (19, 20, 21, 22)

23. An apparatus for allocating base station resources during a tune away, comprising:
-
means for determining when an access terminal is going to undertake a tune-away; means for expiring resource assignments implicitly at a frame boundary associated with the access terminal prior to the tune-away; and means for allocating base station resources associated with the access terminal to one or more disparate access terminals during the tune-away. - View Dependent Claims (24, 25, 26)

27. A computer-readable medium having stored thereon computer-executable instructions for:
-
receiving an indication that a tune-away will occur at time t1 with respect to a first access terminal; locating a latest frame boundary that occurs at a first point in time prior to t1; implicitly expiring reverse link resource assignments at the first point in time; implicitly expiring forward link resource assignments at the first point in time; suspending transmissions on a reverse link after the reverse link resource assignments have been expired; suspending monitoring of a forward link after the forward link resource assignments have been expired; re-assigning base station resources from the first access terminal to at least one disparate access terminal beginning at the first point in time; and performing the tune-away at time t1. - View Dependent Claims (28, 29)

30. A processor that executes instructions for allocating resources in a wireless communications environment, the instructions comprising:
-
upon receiving an indication that an access terminal will perform a tune-away, locating a frame boundary just prior to performance of the tune-away; expiring resource assignments associated with the access terminal at a time associated with the frame boundary; and reallocating base station resources associated with the access terminal to at least one disparate access terminal during the tune-away. - View Dependent Claims (31)
