Network access selection between access networks
First Claim
1. A method of controlling selection by a user terminal between a first access network and a second access network providing overlapping coverage with the first access network, the method comprising:
- obtaining a performance measurement comprising a throughput for a group of one or more cells in the second access network that are correlated with a cell in the first access network;
computing an admission threshold for the cell in the first access network based on the throughput; and
controlling the admission of a user terminal operating in the second access network to the cell in the first access network based on the admission threshold.

Abstract
WI-FI/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and WI-FI cells. Cellular network cells providing overlapping coverage with WI-FI cells are correlated with the WI-FI cells. A received signal strength threshold is determined for each WI-FI cell based on an average throughput of the cellular network cells correlated with the WI-FI cell. The WI-FI user terminal admit threshold is used to control the effective coverage of the WI-FI cell. A user terminal operating within a cellular network cell is admitted to a WI-FI only if it is within the effective coverage area of the WI-FI cell as determined by the received signal strength threshold. Increasing the threshold shrinks the effective coverage area of the WI-FI cell to allow user terminal only of strong RSSI to make connection to the Cell, and steers user terminal of weak RSSI away from the WI-FI cell. In contrary, decreasing the threshold expands the effective coverage area of the WI-FI cell and effectively allows more user terminal making connection to the WI-FI cell.
