Abstract
Communication network techniques may use geographic information to reduce a number of neighboring cell measurements to be taken. Such techniques may be useful, for example, in cell reselection.
Claims16
A method, comprising:
- receiving, by a mobile device, a signal indicating that a cell is a representative cell that is located at an edge of a coverage area of a carrier frequency of a network, wherein the signal indicates that the cell is a sector boundary cell;
- receiving, by the mobile device, a radial indication indicating a radial direction of the coverage area;
- determining a current location of the mobile device;
- based on the signal, the radial indication, and the current location, determining whether to perform measurements of the carrier frequency;
- and
- in response to determining to perform the measurements, performing the measurement of the carrier frequency with a decreased frequency of monitoring based on a decreasing signal strength of the carrier frequency.

A mobile device, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions for execution by the processor, the programming instructions instruct the one or more processors to:
- receive a signal indicating that a cell is a representative cell that is located at an edge of a coverage area of a carrier frequency of a network, wherein the signal indicates that the cell is a sector boundary cell;
- receive a radial indication indicating a radial direction of the coverage area;
- determine a current location of the mobile device;
- based on the signal, the radial indication, and the current location, determine whether to perform measurements of the carrier frequency;
- and
- in response to determining to perform the measurements, perform the measurement of the carrier frequency with a decreased frequency of monitoring based on a decreasing signal strength of the carrier frequency.
