Signal Quality Determination Methods And Apparatus Suitable For Use In WLAN-To-WWAN Transitioning

A computer program product, comprising:

• a non-transitory computer readable medium;
• computer instructions stored in the non-transitory computer readable medium;
• the computer instructions being executable by one or more processors of a mobile terminal for use in switching communications from a first wireless network and a second wireless network by:
• determining a transmission error value for transmissions from the mobile terminal to the first wireless network based on a count of data packet errors of the transmissions identified over a predetermined time period;
• calculating 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;
• and
• when the transmission error percentage error value is greater than a predetermined error percentage value, providing the indication to switch the communication operations from the first wireless network to a second wireless network.

A mobile terminal configured to communicate in a first wireless network and a second wireless network, the mobile terminal comprising:

• a first transceiver portion configured for communicating via a first wireless network;
• a second transceiver portion configured for communicating via a second wireless network;
• one or more processors coupled to the first and the second transceiver portions;
• the one or more processors configured for:
• determining a transmission error value for transmissions from the mobile terminal to a first wireless network based on a count of data packet errors of the transmissions identified over a predetermined time period;
• calculating 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;
• and
• when the transmission error percentage error value is greater than a predetermined error percentage value, providing the indication to switch the communication operations from the first wireless network to a second wireless network.
