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.

Abstract: A mobile terminal performs communication operations for maintaining a voice or data call via a wireless AP of a WLAN. During this time, the mobile terminal identifies a RSSI value and a SNR value of an RF signal of the wireless AP. When the RSSI value is less than a predetermined RSSI value, and the SNR value is less than a predetermined SNR value, the mobile terminal provides an indication to switch the communication operations from the WLAN to a WWAN. However, when the RSSI value is less than the predetermined RSSI value, but the SNR value is greater than the predetermined SNR value, the mobile terminal provides an indication to maintain the communication operations in the WLAN. In a concurrent process, the mobile terminal determines a transmission error value for data packet transmissions based on a count of data packet errors.

Abstract: A mobile terminal is adapted to operate in a WLAN and a WWAN. The mobile terminal performs communication operations using its WLAN transceiver portion for maintaining a voice or data call via a wireless AP of the WLAN. During this time, the mobile terminal identifies a RSSI value and a SNR value of an RF signal of the wireless AP. When the RSSI value is less than a predetermined RSSI value, and the SNR value is less than a predetermined SNR value, the mobile terminal provides an indication to switch the communication operations from the WLAN to the WWAN.
