Abstract
A wireless user device selects wireless networks. The wireless user device determines signal strength for the wireless networks and identifies candidate ones of the wireless networks based on their signal strength. The wireless user device obtains performance information for the candidate wireless networks that comprises data throughput, error rate, band fading, and/or intermodulation. The wireless user device selects one of the candidate wireless networks based on the performance information. The wireless user device wirelessly exchanges data with the selected one of the candidate wireless networks.
Claims20
A method to select wireless networks, the method comprising:
- wirelessly indicating UE capabilities to a home wireless network;
- in response to indicating the UE capabilities to the home wireless network, wirelessly receiving, from the home wireless network, performance information for the home wireless network and for roaming wireless networks, wherein the performance information comprises data throughput and error rate;
- measuring signal strength for the roaming wireless networks;
- determining candidate ones of the roaming wireless networks based on the signal strength for the roaming wireless networks;
- determining performance differentials between the performance information for the home wireless network and the performance information for each of the candidate ones of the roaming wireless networks;
- ranking the candidate ones of the roaming wireless networks based on the performance differentials;
- determining that at least one of the candidate ones of the roaming wireless networks exceeds a performance differential threshold;
- selecting a highest ranked one of the candidate ones of the roaming wireless networks that exceeded the performance differential threshold;
- and
- wirelessly exchanging data with the selected one of the candidate ones of the roaming wireless networks.
