Abstract:
A mobile terminal operates to switch communications from a first wireless network to a second wireless network. The mobile terminal determines a transmission error value for transmissions to the first wireless network based on a count of data packet errors of the transmissions identified over a predetermined time period. The mobile terminal then calculates a transmission error percentage value based on the transmission error value and a total number of attempted data packet transmissions over the predetermined time period. When the transmission error percentage error value is greater than a predetermined error percentage value, the mobile terminal provides an indication to switch the communication operations from the first wireless network to the second wireless network.
