Abstract
A device and method include detecting signal strength received at a mobile cellular communication device. A dropped call is detected between the device and another device as a function of detected signal strength. The dropped call is reconnected when detected signal strength reaches a selected first threshold.
Claims15
A method comprising:
- detecting signal strength received at a first mobile cellular communication device during an active call between the first mobile cellular communication device and a second mobile cellular communication device;
- in response to the detected signal strength being below a predetermined first threshold, detecting the call could potentially be dropped, and sending a first message to the second device related to such drop;
- in response to the detected signal strength received at the first device being below a predetermined second threshold and a call end function not being selected by a user of the first device, sending a second message to the second device prompting a user of the second device to select whether to reestablish the call in response to the signal strength received at the first device increasing;
- and
- based on a selection of the user of the second device in response to the prompting, reconnecting the dropped call only if the detected signal strength received at the first device reaches a predetermined third threshold, wherein the third threshold is a signal strength known to provide a stable call that is not likely to be dropped.

A computer readable storage device for storing programming code to cause a communication device to execute a method, the method comprising:
- detecting signal strength received at a first mobile cellular communication device during an active call between the first device and a second mobile cellular communication device;
- in response to the signal strength being below a predetermined first threshold, detecting the call could potentially be dropped, and sending a first message to the second device related to such drop;
- in response to the detected signal strength received at the first device being below a predetermined second threshold and a call end function not being selected by a user of the first device, sending a second message to the second device prompting a user of the second device to select whether to reestablish the call in response to the signal strength received at the first device increasing;
- and
- based on a selection of the user of the second device in response to the prompting, reconnecting the dropped call only if the detected signal strength received at the first device reaches a predetermined third threshold, wherein the third threshold is a signal strength known to provide a stable call that is not likely to be dropped.

A first mobile cellular communication device comprising:
- a module to detect signal strength received during an active call between the first device and a second mobile cellular communication device;
- a module to, in response to the signal strength being below a predetermined first threshold, detect the call could potentially be dropped, and send a first message to the second device related to such drop;
- a module to, in response to the detected signal strength received at the first device being below a predetermined second threshold and a call end function not being selected by a user of the first device, send a second message to the second device prompting a user of the second device to select whether to reestablish the call in response to the signal strength received at the first device increasing;
- and
- a module to, based on a selection of the user of the second device in response to the prompt, reconnect the dropped call only if the detected signal strength received at the first device reaches a predetermined third threshold, wherein the third threshold is a signal strength known to provide a stable call that is not likely to be dropped.
