Wakeup method for devices in power saving mode

A wireless communication device comprising:

• a baseband processing unit comprising:
• a wakeup detector configured to:
• receive a wireless signature beacon signal;
• determine that the received wireless signature beacon signal matches the selected wakeup signature beacon signal;
• and
• generate a wake up signal, in response to determining that the received wireless signature beacon signal matches the selected wakeup signature beacon signal;
• and
• an application processing unit comprising:
• a power manager configured to:
• cause the wireless communication device to enter a power saving mode;
• receive the wake up signal from the wakeup detector;
• and
• perform a wakeup process, in response to receiving the wakeup signal wherein the wakeup process causes the wireless communication device to exit the power saving mode.

A wireless access network system comprising:

• a plurality of devices configured to:
• receive a wakeup request from a machine-type communication interworking function (MTC-IWF) device;
• identify a wireless communication device associated with the received wakeup request;
• map the received wakeup request to a wakeup signature beacon signal based on the identified wireless communication device;
• generate the wakeup signature beacon signal;
• and
• transmit the generated wakeup signature beacon signal.
