Abstract:
1. A system for wirelessly exchanging communications with at least one mobile unit, the system comprising: a first base station unit coupled to a network; a second base station unit coupled to the network, wherein the first and second base station units are configured to communicate wirelessly with the mobile unit under a Bluetooth protocol; wherein the first and second base station units are further configured for: a system controller coupled to the first and second base station units and to the network, wherein the system controller includes a Dynamic Host Configuration Protocol (“DHCP”) server, wherein requesting a unique session address includes: wherein the first and second base station units include: upper and lower Bluetooth protocol stacks, a mobility protocol to perform generic mobility link establishing and link clearing, a mobility management entity, configured to operate above the HCI, for providing a protocol independent interface between the mobility protocol and the upper layers of the Bluetooth protocol stack, wherein the upper layers operate above the HCI, and a mobility process, configured to operate below the HCI, for interfacing between the mobility management entity and the lower layers of the Bluetooth protocol stack, wherein the lower layers operate below the HCI; wherein the second base station is configured to determine that the communication link with the mobile unit is lost or cleared and provide a message to the system controller, and wherein the system controller releases the unique BD_ADDR in response to the received message.
