Cell reselection based on information collected from a plurality of mobile devices
First Claim
1. A method performed by a mobile device, the method comprising:
- establishing a first cellular communication link with a serving cell in a cellular communications network;
receiving information associated with at least one cell in the cellular communications network, wherein the information is received in a wireless manner, wherein the information is obtained based on call information collected from a plurality of mobile devices operating in the cellular communications network, wherein the information is useable in cell reselection; and
performing cell reselection in the cellular communications network based on the information, where the method is performed at least in part by one or more computer processors of the mobile device.

Abstract
Data provided by an access point of a wireless local area network (“WLAN”) is used to assist a mobile device in cell reselection. If a serving cell of a cellular communications network is unsuitable for providing cellular service, a candidate cell co-located with the serving cell can be selected as the serving cell based on quality of service metrics associated with the serving cell and the candidate cell. The mobile device can be proactively commanded to switch to the candidate cell for receiving cellular service. In some implementations, the quality of service metrics are calculated from call logs collected from mobile devices operating in the cellular communications network. In some implementations, network information regarding serving cell performance can be used with the call logs to generate the quality of service metrics.
