Cell selection offset used to indicate wireless cell unsuitable for communications

摘要

Embodiments disclosed herein provide systems and methods for compelling a cell selection metric to indicate that a wireless cell is not suitable for communications. In a particular embodiment, a method provides receiving system information from a base station of a visited wireless communication network. The method further provides calculating a cell selection metric from cell selection parameters within the system information and a cell selection offset stored in the wireless communication device, wherein the cell selection offset causes the cell selection metric to indicate an unsuitable wireless cell. The method further provides receiving a request for a data connection from an application executing on the wireless communication device and, in response to the request, recalculating the cell selection metric from the cell selection parameters without the cell selection offset. The method further provides determining whether the wireless cell is suitable for communications based on the cell selection metric.

主权项

1. A method of operating a wireless communication device, comprising:
receiving system information from a base station of a visited wireless communication network, wherein the system information includes at least a portion of cell selection parameters for a wireless cell of the base station; calculating a cell selection metric from the cell selection parameters and a cell selection offset stored in the wireless communication device, wherein the cell selection offset causes the cell selection metric to indicate that the wireless cell is not suitable for communications; receiving a request for a data channel from an application executing on the wireless communication device; in response to the request, recalculating the cell selection metric from the cell selection parameters without the cell selection offset; and determining whether the wireless cell is suitable for communications based on the recalculated cell selection metric.
