Abstract
A user equipment (UE) expedites cell reselection by reselecting a neighbor cell prior to call setup. In one instance, the UE measures a signal quality of a serving cell and a signal quality of the neighbor cell. The UE starts a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell. The UE reselects the neighbor cell prior to a scheduled expiration of the reselection timer.
Claims16
A method of wireless communication, comprising:
- measuring a signal quality of a serving cell and a signal quality of a neighbor cell;
- starting a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell;
- and
- reselecting the neighbor cell prior to a scheduled expiration of the reselection timer based on a pending call setup, wherein the neighbor cell is reselected prior to the call setup.
A user equipment (UE), comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- measure a signal quality of a serving cell and a signal quality of a neighbor cell;
- start a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell;
- and
- reselect the neighbor cell prior to a scheduled expiration of the reselection timer based on a pending call setup, wherein the neighbor cell is reselected prior to the call setup.
An apparatus of wireless communication, comprising:
- means for measuring a signal quality of a serving cell and a signal quality of a neighbor cell;
- means for starting a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell;
- and
- means for reselecting the neighbor cell prior to a scheduled expiration of the reselection timer based on a pending call setup, wherein the neighbor cell is reselected prior to the call setup.
A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising codes executable for a processor to perform:
- measuring a signal quality of a serving cell and a signal quality of a neighbor cell;
- starting a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell;
- and
- reselecting the neighbor cell prior to a scheduled expiration of the reselection timer based on a pending call setup, wherein the neighbor cell is reselected prior to the call setup.
