Handover of call serviced by modular ear-piece/microphone between servicing base portions

A wireless headset operable to service a call transferred from a first base unit to a second base unit, the wireless headset comprising:

• at least one wireless interface operable to wirelessly couple the wireless headset and the first base unit and/or the second base unit via a wireless personal area network (WPAN);
• a earpiece communicatively coupled to the at least one wireless interface, wherein the earpiece renders an inbound portion of the call audible;
• a microphone communicatively coupled to the at least one wireless interface, wherein the microphone is operable to produce an outbound portion of the call;
• a processing module communicatively coupled to the at least one wireless interface, wherein the processing module is operable to:
• initiate a handover of the serviced call, having an associated address, from a first communication pathway serviced from a service network via the first base unit to a second communication pathway serviced from the service network via the second base unit, wherein the second communication pathway is established based on the address associated with the serviced call;
• initiate call control functions between the wireless headset and the servicing network operably coupled to the second base unit;
• service the call between the wireless headset and the servicing network that couples to the second base unit;
• and
• anchor the call to the wireless headset;
• and
• a user interface communicatively coupled to the processing module, wherein the processing module is operable to initiate commands and/or call control functions based upon user input.

A method to service calls between a destination terminal accessible by a servicing network, and a wireless headset, the method comprising:

• establishing a first wireless personal area network (WPAN), wherein the first WPAN operably couples a first base unit and the wireless headset, wherein:
• the wireless headset supports all of a WPAN protocol stack and a plurality of upper layers of the servicing network protocol stack;
• and
• the first base unit supports a plurality of lower layers of the servicing network protocol stack;
• operably coupling the first WPAN to the servicing network using the first base unit;
• servicing calls with a first communication pathway between the destination terminal, having an associated address, and the wireless headset via the operably coupled servicing network and first WPAN that are coupled together using the first base unit, wherein a subscriber or system identification module (SIM) within the wireless headset is operable to support SIM functions for the first base portion;
• detecting the presence of a second base unit, wherein the second base unit is operable to support the plurality of lower layers of the servicing network protocol stack;
• establishing a second WPAN, wherein the second WPAN operably couples the second base unit and the wireless headset;
• operably coupling the second WPAN to the servicing network using the second base unit;
• based on the address associated with the destination terminal, establishing a second communication pathway between the destination terminal and the wireless headset via the operably coupled servicing network and second WPAN that are coupled together using the second base unit;
• and
• initiating, with the wireless headset, a handoff of the calls from the first communication pathway to the second communication pathway;
• servicing the calls with the second communication pathway;
• and
• terminating the first communication pathway.
