Mobile communication systems and devices, and method for an event-triggered measurement report

A method for an event-triggered measurement report, executed by a mobile communication system comprising a base station, a WLAN AP configured with a serving AP ID and a neighboring AP ID, and a mobile communication device connected to the WLAN AP with the serving AP ID, the method comprising:

• transmitting, by the base station, a first measurement configuration comprising a first threshold value and a second threshold value which is less than the first threshold value to the mobile communication device;
• measuring, by the mobile communication device, a first signal strength of the WLAN AP with the serving AP ID according to the first measurement configuration;
• measuring, by the mobile communication device, a second signal strength of the WLAN AP with the neighboring AP ID according to the first measurement configuration;
• and
• transmitting, by the mobile communication device, a first measurement report to the base station when the first signal strength is less than the first threshold value and the second signal strength is greater than the second threshold value.

A mobile communication device, comprising:

• a first wireless transceiver, configured to perform wireless transmission and reception to and from a base station;
• a second wireless transceiver, configured to connect to a WLAN AP with a serving AP ID, wherein the WLAN AP is configured with the serving AP ID and a neighboring AP ID;
• and
• a controller, configured to measure a first signal strength of the WLAN AP with the serving AP ID via the second wireless transceiver, measure a second signal strength of the WLAN AP with the neighboring AP ID via the second wireless transceiver, and transmit a first measurement report to the base station via the first wireless transceiver when the first signal strength is less than a first threshold value and the second signal strength is greater than a second threshold value,
• wherein the second threshold value is less than the first threshold value.
