Abstract

A network (100) includes a hub device (110) and at least one unattached peripheral device (120). The unattached peripheral device (120) transmits an attach request to the hub device (110) with a selected address, receives a new address from the hub device to identify the unattached peripheral device (120), and communicates with the hub device (110) using the new address.

subsequent to the hub response, sending by the first peripheral device to the hub device, a second peripheral response including the first peripheral device address, and

sending, by the hub device, one or more additional identifiers to the first peripheral device, wherein the one or more identifiers are used to further identify communications between the hub device and the first peripheral device,

prior to sending, by the hub device to the first peripheral device, the signal including the first peripheral device address, broadcasting by the hub device, a message including a hub device identifier to indicate availability of the hub device for peripheral attachment, and

in response to the message broadcast by the hub device, sending by the first peripheral device, a message to indicate availability of the first peripheral device for communication with the hub device.

2. The method according to claim 1, wherein the first peripheral device address is based at least in part on a MAC address of the first peripheral device.

3. The method according to claim 2, wherein the MAC address for the first peripheral device includes an AMAC address for the first peripheral device.

4. The method according to claim 2, wherein the MAC address for the first peripheral device is different from an AMAC address for the first peripheral device.

5. The method according to claim 1, wherein the hub device performs the steps of managing network timing with one or more peripheral devices to allocate available bandwidth among the peripheral devices with which the hub device is communicating.

6. The method according to claim 1 comprising communicating, by the hub device, with at least one additional peripheral device having a peripheral device address different from the address of the first peripheral device.

7. The method according to claim 1 comprising broadcasting a message from the hub device to a plurality of peripheral devices with which the hub device is attached, the message including an address for the hub device.

8. The method according to claim 1, wherein the message broadcast from the hub device includes a range of peripheral device addresses, one of which being the address of the first peripheral device.

9. The method according to claim 8 comprising receiving at the hub device, addresses within the range of the address of the peripheral device for a plurality of other peripheral devices indicating their availability for communication with the hub device in response to the message broadcast by the hub device.

10. The method according to claim 1, wherein the one or more additional identifiers include a stream number for identifying a particular communication channel between the peripheral device and the hub device.

11. The method according to claim 1, wherein the one or more additional identifiers include a token that includes a stream number for identifying a particular communication channel between the peripheral device and the hub device and the address for the peripheral device.

12. A hub device within a personal area network comprising,

a transceiver,

a processor in communication with the transceiver, and

A program on a computer readable medium configured for enabling the processor to i) send a signal including an address for a first peripheral device, ii) receive from the first peripheral device a response including the first peripheral device address, iii) send a hub response to the first peripheral device, iv) receive from the first peripheral device a second peripheral response including the first peripheral device address, v) send one or more additional identifiers to the first peripheral device, wherein the one or more identifiers are used to further identify communications between the hub device and first the peripheral device, and vi) prior to sending a signal including the first peripheral device address to the first peripheral device, broadcast a message including a hub device identifier to indicate the availability of the hub device for first peripheral device attachment and receive, from the first peripheral device, a message indicating the availability of the first peripheral device for communication with the hub device.
