Abstract

Methods and apparatus for a configurable architecture with a converged coordinator are described. The converged coordinator may have multiple radio transceivers or interfaces. The converged coordinator may communicate with a plurality of clusters or Personal Area Networks (PANs). The converged coordinator may include a protocol stack with a Convergence Layer and a Converged Medium Access Control (MAC) layer. The converged coordinator may perform channel switching to allow devices to switch from one channel to another (or from one PAN to another). The method may include active channel switching, passive channel switching, and group-based channel switching, as well as two-step active channel switching and one-step active channel switching. The converged coordinator may perform channel switching due to increased congestion or traffic in a particular cluster or PAN. The method may include new messages and fields within messages for use in channel switching.

First claim

What is claimed is:

1. A computer processing system for switching at least one personal area network (PAN) device from a first PAN in a plurality of personal area networks (PANs) to a second PAN in the plurality of personal area network (PANs), the system comprising:
a processor configured to:
(i) receive, a disassociation notification message, from the at least one PAN device to switch from the first PAN to the second PAN, that comprises an identification of the second PAN;
(ii) generate, in response to the disassociation message, a first instruction for the at least one PAN device to switch to the second PAN, the first instruction comprising an acknowledgement instruction, for sending via a first channel to the at least one PAN device that comprises the identification of the second PAN and a disassociation reason;
(iii) receive, an association request, sent by the at least one PAN device, and
(iv) generate, a second instruction, in response to the association request, that comprises an association response, for sending via a second channel to the at least one PAN device; and
a memory configured to store the first and the second instruction.

2. The system of claim 1 , wherein the association request further comprises an association message, sent by the at least one PAN device to the system, that comprises an identification of the second PAN, and the second instruction comprises an association response, for sending via a first channel to the at least one PAN device, that comprises the identification of the second PAN and that is sent in response to an association message.

3. The system of claim 1 , wherein the processor is further configured to use the identification the second PAN in generating the instruction.

4. A method for switching at least one personal area network (PAN) device from a first PAN in a plurality of personal area networks (PANs) to a second PAN in the plurality of personal area network (PANs), the system comprising:
receiving, at a central processing system for the plurality of PANs, a disassociation notification message sent by the at least one PAN device that comprises an identification of the second PAN, sent by the at least one PAN device indicating that the at least one PAN device is requesting to switch from the first PAN to the second PAN;
sending, in response to the step of receiving, from the central processing system to the at least one PAN device, an acknowledgement instruction in response to the disassociation notification message, for the at least one PAN device to switch from the first PAN to the second PAN, via a first channel to the at least PAN device, that comprises the identification of the second PAN;
receiving an association request, from the at least one PAN device via a second channel; and
sending an association response, to the at least one PAN device, via the second channel, in response to the association request.

5. The method of claim 4 , wherein the acknowledgement instruction further comprises a disassociation reason.

6. The method of claim 4 , wherein receiving the association request, further comprises, receiving the association message via a first channel, sent by the at least one personal area network device to the central processing system, and sending an association response further comprises sending an identification of the second PAN.

7. The method of claim 6 , further comprising receiving an acknowledgement message at the central processing system that was sent by the at least one PAN device via the second channel.
