Abstract
Aspects of managing background public mobile network (BPLMN) searches are described. For example, in an aspect, a user equipment (UE) may determine whether one or more segments of a frequency acquisition from a prior discontinuous reception (DRX) cycle remain to be completed and whether the one or more segments of the frequency acquisition may be performed in a remaining portion of the current DRX cycle. If so, the UE may be configured to perform the one or more segments of the frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time.
Claims20
A method for managing background public land mobile network (BPLMN) search, comprising:
- determining an end of a paging occasion in a current discontinuous reception (DRX) cycle;
- determining whether one or more segments of a first frequency acquisition from a prior DRX cycle remain to be completed;
- determining whether the one or more segments of the first frequency acquisition may be performed in a remaining portion of the current DRX cycle;
- performing the one or more segments of the first frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time;
- and
- saving results from the one or more segments of the first frequency acquisition.
An apparatus for managing background public land mobile network (BPLMN) search, comprising
- a transceiver configured to tune to one or more frequencies to search BPLMNs;
- one or more processors communicatively coupled to the transceiver by one or more buses and configured to:
- determine an end of a paging occasion in a current discontinuous reception (DRX) cycle;
- determine whether one or more segments of a first frequency acquisition from a prior DRX cycle remain to be completed;
- determine whether the one or more segments of the first frequency acquisition may be performed in a remaining portion of the current DRX cycle;
- perform the one or more segments of the first frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time;
- and
- save results from the one or more segments of the first frequency acquisition;
- and
- a memory coupled to the one or more processors to store the results from the one or more segments of the first frequency acquisition.
An apparatus for managing background public land mobile network (BPLMN) search, comprising:
- means for determining an end of a paging occasion in a current discontinuous reception (DRX) cycle;
- means for determining whether one or more segments of a first frequency acquisition from a prior DRX cycle remain to be completed;
- means for determining whether the one or more segments of the first frequency acquisition may be performed in a remaining portion of the current DRX cycle;
- means for performing the one or more segments of the first frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time;
- and
- means for saving results from the one or more segments of the first frequency acquisition.
A computer-readable medium storing computer executable code for managing a background public land mobile network (BPLMN) search, comprising:
- code for determining an end of a paging occasion in a current discontinuous reception (DRX) cycle;
- code for determining whether one or more segments of a first frequency acquisition from a prior DRX cycle remain to be completed;
- code for determining whether the one or more segments of the first frequency acquisition may be performed in a remaining portion of the current DRX cycle;
- code for performing the one or more segments of the first frequency acquisition when the identified remaining portion of the current DRX cycle provides sufficient time;
- and
- code for saving results from the one or more segments of the first frequency acquisition.
