Abstract
A method of wireless communications includes determining a period of time to trigger inter-radio access technology (IRAT) cell reselection. The method also includes adjusting the period of time accordingly, in which the adjusting is based on a target cell signal strength, the target cell belonging to a different RAT than a source cell. The period of time may also be determined based on the source cell signal strength and/or target cell signal strength, and adjusted accordingly.
Claims22
A method of wireless communication, comprising:
- determining a period of time to trigger inter-radio access technology (IRAT) cell reselection;
- and
- adjusting the period of time by a scaling factor based at least in part on a target cell signal strength, a target cell belonging to a radio access technology (RAT) that is different from a RAT of a source cell, the period of time being reduced when the target cell signal strength is above a threshold value.
(canceled)
6-7. (canceled)
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to determine a period of time to trigger inter-radio access technology (IRAT) cell reselection;
- and
- to adjust the period of time by a scaling factor based at least in part on a target cell signal strength, a target cell belonging to a radio access technology (RAT) that is different from a RAT of a source cell, the period of time being reduced when the target cell signal strength is above a threshold value.
(canceled)
13-14. (canceled)
A computer program product for wireless communication in a wireless network, comprising:
- a non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code to determine a period of time to trigger inter-radio access technology (IRAT) cell reselection;
- and
- program code to adjust the period of time by a scaling factor based at least in part on a target cell signal strength, a target cell belonging to a radio access technology (RAT) that is different from a RAT of a source cell, the period of time being reduced when the target cell signal strength is above a threshold value.
(canceled)
An apparatus for wireless communication, comprising:
- means for determining a period of time to trigger inter-radio access technology (IRAT) cell reselection;
- and
- means for adjusting the period of time by a scaling factor based at least in part on a target cell signal strength, a target cell belonging to a radio access technology (RAT) that is different from a RAT of a source cell, the period of time being reduced when the target cell signal strength is above a threshold value.
