Abstract

A collaboration manager server is provided that bridges a PAN with a WAN. When the collaboration manager server receives, from the first mobile device, a request to establish a second network service, wherein the second network service provides for bridging a PAN with a WAN, the collaboration manager server determines a credential to be used by mobile devices who wish to join the second network service and, in response to determining that the first mobile device is authorized to make such a request, establishes the second network service. Further, in response to receiving, from a second mobile device, a request to join the second network service, wherein the request to join the second network service comprises the credential, the collaboration manager server joins the second mobile device to the second network service and bridges traffic between the first mobile device and the second mobile device using the second network service.

Claims

1. A method for bridging a Personal Area Network (PAN) with a wide area network (WAN) at an access point (AP), the method comprising:

receiving, from a first mobile device, a request to authenticate with a collaboration manager service for a first network service;

receiving, from the first mobile device, a request to establish a second network service, wherein the second network service provides for bridging a PAN with a WAN via a collaboration manager server;

determining a credential to be used by mobile devices who wish to join the second network service;

determining that the first mobile device is authorized to make such a request;

establishing the second network service;

receiving, from a second mobile device, a request to join the second network service, wherein the request to join the second network service comprises the credential;

joining the second mobile device to the second network service; and

in response to joining the second mobile device to the second network service, bridging traffic between the first mobile device and the second mobile device using the second network service;

wherein determining that the first mobile device is authorized to make such a request comprises authenticating the first mobile device;

wherein determining the credential comprises;

receiving the credential from the first mobile device in the request to establish the second network service;

or

generating the credential and conveying the credential to the first mobile device;

wherein the credential comprises a routing address of a collaboration manager server.

2. The method of claim 1, wherein joining the second mobile device to the second network service comprises:

authenticating the second mobile device.

3. The method of claim 1, further comprising:

broadcasting a message identifying the second network service, wherein the message comprises the credential; and

in response to advertising the second network service, receiving, from a second mobile device, a request to join the second network service.

4. The method of claim 3, wherein the request comprises the credential included in the message.

5. The method of claim 1, wherein the first and second mobile devices were part of a first Personal Area Network (PAN), and further comprising:

disconnecting, by the second mobile device, from a PAN connection to the first PAN;

connecting, by the second mobile device, to a second PAN different from the first PAN; and

wherein bridging traffic between the first mobile device and the second mobile device using the second network service comprises linking mobile devices of the first PAN with mobile devices of the second PAN via the second network service.

6. A collaboration manager server capable of for bridging a Personal Area Network (PAN) with a wide area network (WAN), the collaboration manager server comprising:

a processor;

an at least one memory device that is configured to store a set of instructions that, when executed by the processor, perform the following functions;

receive, from a first mobile device, a request to authenticate with an access point for a first network service;

receive, from the first mobile device, a request to establish a second network service, wherein the second network service provides for bridging a PAN with a WAN;

determine a credential to be used by mobile devices who wish to join the second network service;

determine that the first mobile device is authorized to make such a request;

establish the second network service;

receive, from a second mobile device, a request to join the second network service, wherein the request to join the second network service comprises the credential;

join the second mobile device to the second network service; and

in response to joining the second mobile device to the second network service, bridge traffic between the first mobile device and the second mobile device using the second network service;

wherein determining that the first mobile device is authorized to make such a request comprises authenticating the first mobile device;

wherein joining the second mobile device to the second network service comprises authenticating the second mobile device;

wherein the set of instructions further comprises instructions that when executed by the processor, perform the following functions;

broadcast a message identifying the second network service, wherein the message comprises the credential; and

in response to advertising the second network service, receive, from a second mobile device, a request to join the second network service;

wherein the request comprises the credential included in the message.

7. The collaboration manager server of claim 6, wherein determining the credential comprises:

receiving the credential from the first mobile device in the request to establish the second network service;

or

generating the credential and conveying the credential to the first mobile device.

8. The collaboration manager server of claim 6, wherein the credential comprises a routing address of a collaboration manager server.
