TRANSITIONING OF MOBILE DEVICES WITHIN A WIRELESS COMMUNICATION NETWORK BETWEEN MULTIPLE RADIO ACCESS TECHNOLOGIES
First Claim
1. A method of wireless communication, comprising:
- entering an idle mode while coupled to a first radio access technology (RAT);
determining that the first RAT does not broadcast cell reselection parameters which enable the UE to move to a higher priority RAT within a same public land mobile network (PLMN);
autonomously initiating an out of service search procedure of a plurality of RATs within the same PLMN as the first RAT while in the idle mode;
determining a priority of one or more RATs detected by the search procedure in relation to the first RAT; and
camping to a second RAT within the one or more detected RATs when the second RAT has a higher priority than the first RAT.

Abstract
Network re-selection by an idle mobile device between multiple radio access technologies (RATs) is provided for communication networks without a network-based solution. When a user equipment (UE) enters idle mode while camped to a first RAT network, it initiates an out of service search procedure that causes the UE to search for other RATs within a same public land mobile network (PLMN). If another RAT network is detected, the UE determines whether the priority of the detected RAT is higher than the priority of the first RAT. When the detected RAT has a higher priority than the first RAT, the UE re-selects and camps to that detected RAT network. If the detected RAT does not have a higher priority or no other RAT is detected within the PLMN, the UE re-camps to the first RAT network.

11. A computer program product for wireless communications in a wireless network, comprising:
a non-transitory computer-readable medium having program code recorded thereon, the program code comprising; program code to enter an idle mode while coupled to a first radio access technology (RAT); program code to determine that the first RAT does not broadcast cell reselection parameters which enable the UE to move to a higher priority RAT within a same public land mobile network (PLMN); program code to autonomously initiate an out of service search procedure of a plurality of RATs within the same PLMN as the first RAT while in the idle mode; program code to determine a priority of one or more RATs detected by the search procedure in relation to the first RAT; and program code to camp to a second RAT within the one or more detected RATs when the second RAT has a higher priority than the first RAT. - View Dependent Claims (12, 13, 14, 15)

16. A user equipment (UE) configured for wireless communication, the UE comprising
at least one processor; - and
a memory coupled to the at least one processor, wherein the at least one processor is configured; to enter an idle mode while coupled to a first radio access technology (RAT); to determine that the first RAT does not broadcast cell reselection parameters which enable the UE to move to a higher priority RAT within a same public land mobile network (PLMN); to autonomously initiate an out of service search procedure of a plurality of RATs within the same PLMN as the first RAT while in the idle mode; to determine a priority of one or more RATs detected by the search procedure in relation to the first RAT; and to camp to a second RAT within the one or more detected RATs when the second RAT has a higher priority than the first RAT. - View Dependent Claims (17, 18, 19, 20)
