Associated device discovery in IMS networks
A method of associating multiple user endpoints (UEs) with a single IMS session in an IMS network having a serving node for controlling at least one IMS session for a user and at least a first access network for providing access to UEs. The method involves associating a first UE with the user and with an IMS session; discovering a second UE in a proximity of the first UE; discovering information about the second UE; communicating the information about the second UE to the serving node; the serving node utilizing computer-implemented policy logic to determine whether to associate the second UE with the user and the IMS session; and if the policy logic determines that the second UE is to be associated, the serving node associating the second UE with the IMS session while retaining the association with the first UE.
1. A method for using a mobile device as a switch, the method comprising:
a first mobile device,
creating a first data session between the first mobile device and a data network;
establishing a Personalized Area Network (PAN);
allowing one or more proximate devices proximate to the first mobile device to discover and register in the PAN;
creating one or more PAN sessions between one or more of the proximate devices and the PAN;
wherein, while the first data session and the one or more PAN sessions are in progress, the first mobile device receives or places circuit-switched voice calls using a circuit-switched cellular network without disrupting the first data session and the one or more PAN sessions.
2. The method of claim 1 wherein the first mobile device is a mobile phone.
3. The method of claim 1 wherein the first mobile device is a tablet.
4. The method of claim 1 wherein the data network is a cellular wireless network.
5. The method of claim 1 wherein the data network is a wifi network.
6. The method of claim 5 wherein the wifi network is further connected to a private data network.
7. The method of claim 1 wherein disrupting a session comprises suspending a session, terminating a session or halting a session.
8. The method of claim 1 , wherein establishing the PAN comprises establishing the PAN using broadcast short-range radio signals, information broadcast from other devices, messages received from other devices, or by polling other devices.
9. The method of claim 8 wherein the short-range radio signals utilize wifi technology.
10. The method of claim 8 wherein the short-range radio signals utilize Bluetooth technology.
11. The method of claim 1 wherein a second proximate device discovers the Personalized Area Network and registers in a second PAN session.
12. The method of claim 11 wherein said second proximate device receives an address from the PAN that makes the second proximate device addressable in the second PAN session.
13. The method of claim 11 wherein said second mobile device receives an address from entities in the data network that makes it addressable in the first data session.
14. A first mobile device configured to act as a switch, comprising:
a first transceiver to communicate with a data network;
a second transceiver to communicate using short-range radio signals;
a processor; and
logic stored in a computer readable medium, which when executed by the processor is configured to:
create a first session with the data network using the first transceiver;
create a second session using the second transceiver;
allow devices proximate to the first mobile device to become aware of and register with the second session; and
provide a switch between the first and second network sessions; and
wherein, during the first and second sessions, the first mobile device allows the proximate devices registered in the second session to be given addresses that make them addressable in the first session and/or the second session, and, wherein the first mobile device is able to simultaneously receive or place voice calls using a circuit switched network without disrupting the first session and the second session.
