Abstract
In various aspects, the disclosure provides for cell selection including determining a gain of an antenna associated with a user equipment (UE), adding an offset to a threshold to yield a power threshold, wherein the offset is based on the gain of the antenna, selecting a wireless network, obtaining a power measurement associated with a cell within the selected wireless network, and comparing the power measurement with the power threshold to yield a comparison.
Claims28
A method of cell selection comprising:
- determining a gain of an antenna associated with a user equipment (UE);
- adding an offset to a threshold to yield a power threshold, wherein the offset is based on the gain of the antenna;
- selecting a wireless network;
- obtaining a power measurement associated with a cell within the selected wireless network;
- comparing the power measurement with the power threshold to yield a comparison;
- checking a list in a database for a Visitor public land mobile network (VPLMN);
- and
- triggering a search for one or more roaming public land mobile networks (PLMNs), if the VPLMN is not found on the list.
An apparatus of cell selection comprising:
- a processor for determining a gain of an antenna associated with a user equipment (UE) and for selecting a wireless network;
- a receiver coupled to the processor for adding an offset to a threshold to yield a power threshold, wherein the offset is based on the gain of the antenna;
- and
- a power detector coupled to the receiver for obtaining a power measurement associated with a cell within the selected wireless network;
- and for comparing the power measurement with the power threshold to yield a comparison;
- and wherein the processor is further configured for checking a list in a database for a Visitor public land mobile network (VPLMN) and for triggering a search for one or more roaming public land mobile networks (PLMNs), if the VPLMN is not found on the list.
An apparatus of cell selection comprising:
- means for determining a gain of an antenna associated with a user equipment (UE);
- means for adding an offset to a threshold to yield a power threshold, wherein the offset is based on the gain of the antenna;
- means for selecting a wireless network;
- means for obtaining a power measurement associated with a cell within the selected wireless network;
- means for comparing the power measurement with the power threshold to yield a comparison;
- means for checking a list in a database for a Visitor public land mobile network (VPLMN);
- and
- means for triggering a search for one or more roaming public land mobile networks (PLMNs), if the VPLMN is not found on the list.
A non-transitory computer-readable storage medium storing computer executable code, operable on a device comprising at least one processor;
- a memory for storing one or more of a network identifier or a cell identifier, the memory coupled to the at least one processor;
- and the computer executable code comprising:
- instructions for causing the at least one processor to determine a gain of an antenna associated with a user equipment (UE);
- instructions for causing the at least one processor to add an offset to a threshold to yield a power threshold, wherein the offset is based on the gain of the antenna;
- instructions for causing the at least one processor to select a wireless network;
- instructions for causing the at least one processor to obtain a power measurement associated with a cell within the selected wireless network;
- instructions for causing the at least one processor to compare the power measurement with the power threshold to yield a comparison;
- and
- instructions for causing the at least one processor to check a list in a database for a Visitor public land mobile network (VPLMN);
- and
- instructions for causing the at least one processor to trigger a search for one or more roaming public land mobile networks (PLMNs), if the VPLMN is not found on the list.
