Method and Apparatus for a Battery Saver Utilizing a Sleep and Vacation Strategy

A method of saving power within a vehicle that includes a cellular communication module, the steps comprising:

• generating a first signal to activate an extended power mode in the cellular communication module, wherein the extended power mode allows the cellular communication module to establish a data session with a cellular communication network;
• generating a second signal to activate a low power mode in the cellular communication module upon the extended power mode lapsing, wherein the low power mode allows the cellular communication module to maintain a registered cellular connection with the cellular communication network;
• and
• generating a third signal to activate a sleep mode in the cellular communication module upon the low power mode lapsing, wherein the sleep mode is temporarily disconnected from the cellular communication network.

A vehicle module, comprising:

• a processor configured to:
• activate a telematics control unit's (TCU) extended power mode to establish a data session with a telecommunication network;
• activate a TCU's low power mode to maintain a registered cellular connection with the network upon the extended power mode lapsing;
• activate a TCU's sleep mode including a wake-up cycle upon the low power mode lapsing;
• and
• activate a TCU's deep sleep mode which is disconnected from the network.
