Methods and apparatus for optimizing power-consumption and signaling overhead in mobile communication devices

A wireless communication device comprising:

• means for measuring accumulated data volume of one or more data calls received and transmitted in the device during a first time period during which the device is in a connected state;
• means for determining whether the accumulated data volume exceeds a predetermined threshold after the first time period;
• means for setting a second time period to a first value if the accumulated data volume does not exceed the predetermined threshold, and to a second value if the accumulated data volume equals or exceeds the predetermined threshold, wherein the second time period measures a time of the connected state;
• means for determining when the second time period expires;
• and
• means for sending a signaling message to signal release of the connected state when at least the second time period has expired.

An apparatus comprising:

• at least one processor to:
• measure accumulated data volume of one or more data calls received and transmitted in a wireless device during a first time period during which the device is in a connected state;
• determine whether the accumulated data volume exceeds a predetermined threshold after the first time period;
• set a second time period to a first value if the accumulated data volume does not exceed the predetermined threshold, and to a second value if the accumulated data volume equals or exceeds the predetermined threshold, wherein the second time period measures a time of the connected state;
• determine when the second time period expires;
• and
• send a signaling message to signal release of the connected state when at least the second time period has expired;
• and
• a memory in communication with the at least one processor.

A non-transitory computer program product comprising:

• a computer-readable medium comprising:
• code for causing a computer to measure accumulated data volume of one or more data calls received and transmitted in a wireless device during a first time period during which the device is in a connected state;
• code for causing a computer to determine whether the accumulated data volume exceeds a predetermined threshold after the first time period;
• code for causing a computer to set a second time period to a first value if the accumulated data volume does not exceed the predetermined threshold, and to a second value if the accumulated data volume equals or exceeds the predetermined threshold, wherein the second time period measures a time of the connected state;
• code for causing a computer to determine when the second time period expires;
• and
• code for causing a computer to send a signaling message to signal release of the connected state when at least the second time period has expired.
