Abstract
A method and apparatus for wireless network selection by a wireless mobile device is disclosed. In one embodiment, network performance metrics related to the wireless networks to be considered can be evaluated. The network performance metrics can be weighted and a related ranking metric can be determined. The ranking metric can be used to select a wireless network. In one embodiment, network performance metrics can include a round trip time, which describes a round trip data transit time between the wireless mobile device to a particular network device, and a power metric describing the amount of power needed to transfer an amount of data.
Claims23
A method for selecting a radio access technology for use by a wireless mobile device, the method comprising:
- gathering network performance data corresponding to radio access technologies available to the wireless mobile device;
- selecting a weighting profile corresponding to a selected operational mode;
- weighting the network performance data in accordance with the selected weighting profile;
- determining a ranking metric in accordance with the weighted network performance data;
- and
- selecting a radio access technology in accordance with the determined ranking metric.
A wireless device capable of connecting through one of at least two radio technologies, the wireless device comprising:
- a first radio transceiver;
- a second radio transceiver, wherein the radio access technology of the first radio transceiver is different from the second radio transceiver;
- a selector for coupling data between a processor and the first and the second radio transceivers, wherein the processor is configured to select the first or the second radio transceiver by:
- gathering radio performance data from the first and the second radio transceivers, wherein radio performance data includes round trip time (RTT) and power per byte
- weighting the radio performance data;
- determining at least one metric in accordance with weighted radio performance data;
- and
- selecting the first or the second radio transceiver in accordance with the at least one metric.
Non-transient computer readable medium for storing computer code executable by a processor in a wireless device having at least two wireless data transceivers, and a memory, the computer readable medium comprising:
- computer code for gathering network performance data, wherein the network performance data includes round trip time (RTT) and power per data unit;
- computer code for selecting a weighting profile;
- computer code for weighting the network performance data;
- computer code for determining at least one metric in accordance with weighted network performance data;
- and
- computer code for selecting a radio transceiver in accordance with the at least one metric.
