System and method for facilitating accelerated network selection in a radio network environment
First Claim
1. A method performed by a wireless user equipment (UE) device for facilitating accelerated network selection, the method comprising:
- storing information on the UE device regarding power-off time and power-off location as the UE device is about to enter a power-off condition, the power-off location comprising identification of a current access point; and
upon power-up, the UE device performing the following actions;
computing an estimated distance that the UE device has traveled while in the power-off condition using the stored information and a current time,defining a boundary that lies the estimated distance from a location indicated by the power-off location,for a plurality of regions lying within the boundary, sorting or logically sequencing acquisition records that are associated with the regions in a system acquisition database structure, the sorting or logically sequencing being based on the regions nearness to the boundary, andlocating a network via scanning using scanning data obtained from the logically sequenced acquisition records.

Abstract
A method for facilitating accelerated network selection on a wireless user equipment (UE) device includes storing information regarding power-off time and power-off location as the UE device is about to enter a power-off condition. Upon power-up, the method further includes computing an estimated distance that the UE device has traveled while in the power-off condition using the stored information and a current time, defining a boundary that lies the estimated distance from a location indicated by the power-off location, for a plurality of regions lying within the boundary, logically sequencing acquisition records that are associated with the regions in a system acquisition database structure based on the regions nearness to the boundary, and locating a network via scanning using scanning data obtained from the logically sequenced acquisition records.

11. A wireless user equipment (UE) device comprising:
-
a microprocessor operably coupled to a transceiver and to a memory; instructions, stored in the memory, for storing information on the UE device regarding power-off time and power-off location as the UE device is about to enter a power-off condition, the power-off location comprising identification of a current access point; and instructions, stored in the memory and operable upon power-up, for the UE to perform the following actions; computing an estimated distance that the UE device has traveled while in the power-off condition using the stored information and a current time, defining a boundary that lies the estimated distance from a location indicated by the power-off location, sorting or logically sequencing acquisition records in a system acquisition database structure that are associated with regions lying within the boundary, the sorting or logical sequencing being based on a nearness to the boundary of the regions, and locating a network via scanning using scanning data obtained from the logically sequenced acquisition records. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
