Abstract

A method and apparatus to transfer a data session from one device connected to a residential gateway to another. The transfer is completed within the residential gateway, without routing data through the service provider'"'"'s network. In one embodiment, a native address of a communication device engaged in an active data session is stored in a memory as a temporary device address. A session address in memory is set equal to the stored temporary device address and the temporary device address is associated with the session address in memory. When a request to transfer the data session to another device is received, the temporary device address in memory set to the native address of the new communication device and the session history is sent to the new device. Any new data received in the session, intended for the original device, is routed by a data session handling engine to the new communication device.

Claims

1. A method, comprising:

establishing a communication session comprising data on a service provider'"'"'s network between a first communication device and a second communication device; and

transferring, by a residential gateway, the communication session comprising the data from the second communication device to a third communication device without routing the communication session through the service provider'"'"'s network;

the establishing comprises storing a native address of the second communication device in a memory as a temporary device address, setting a session address in memory equal to the stored temporary device address and associating the temporary device address with the session address in memory;

detecting a unique pattern signaling a transfer request and wherein the transferring further comprises setting the temporary device address in memory to a native address of the third communication device.

2. The method of claim 1, wherein the temporary device address in memory is set by a device switching monitor and control function module of a data session handling engine in the residential gateway.

3. The method of claim 1, wherein the transferring further comprises sending a copy of a session history stored in memory to the third communication device.

4. The method of claim 3, wherein the transferring further comprises routing data intended for the second device to the third device identified by temporary device address in memory.

5. The method of claim 1, further comprising mapping, by a data bridge function module of a data session handling engine in the residential gateway, a message identity label in an outgoing message to the value stored in memory at the session address location.

6. The method of claim 1, further comprising terminating the communication session between the first device and the third device.

7. The method of claim 1, wherein the data comprises any communication information other than voice.

8. The method of claim 1, wherein the data comprises at least one of a short message service (SMS) message, a multimedia messaging service (MMS) message, and caller ID information.

9. The method of claim 1, wherein the communication session comprising data is established on a circuit switched communication network.

10. The method of claim 1, wherein the first second and third communication devices comprise at least of one of a Universal Mobile Telecommunications System (UMTS) handset, a Digital Enhanced Cordless Telecommunications (DECT) handset and a computer.

11. The method of claim 1, wherein the service provider'"'"'s network operates in a licensed spectrum.

12. The method of claim 1, wherein the residential gateway operates in an unlicensed spectrum.

13. The method of claim 1, wherein the communication session comprising the data is transferred by a data copier and switch module of a data session handling engine in the residential gateway.

14. A data session handling engine appratus, comprising:

a first communication interface to communicatively couple a first communication device to the data session handling engine;

a second communication interface to communicatively couple a second communication device to the data session handling engine;

a memory to store a temporary device address location and a session address location; and

a data copier and switch module coupled between the first and second communication interfaces and the memory, the data copier and switch module to transfer a communication session comprising data from the first communication device to the second communication device and wherein the apparatus further comprises a device switching monitor and control function module coupled to the data copier and switch module and to memory, the device switching monitor and control function module monitor for a unique pattern in data received from the first and second communication devices and write a device address into memory at the temporary device address location.

15. The apparatus of claim 14, wherein the data copier and switch module is configured to transfer the communication session without routing the communication session through a service provider'"'"'s network.

16. The apparatus of claim 15, wherein the data comprises any communication information other than voice.

17. The apparatus of claim 14, wherein the memory further comprises a session history location.

18. The apparatus of claim 14, wherein the unique pattern is configured to signal a device transfer request.

19. The apparatus of claim 14, further comprising a device access software push update function module coupled to the data copier and switch module, the device access software push update function module to push a software update to the second communication device.

20. The apparatus of claim 14, further comprising a data bridge function module coupled to the data copier and switch module, the data bridge function module to map a message identity label in an outgoing message to the value stored in memory at the session address location.

21. A computer readable storage medium including instructions that, when executed by a processing system, cause the processing system to perform a method comprising:

establishing a communication session comprising data on a service provider'"'"'s network between a first communication device and a second communication device; and

transferring, by a residential gateway, the communication session comprising the data from the second communication device to a third communication device, the transferring comprises transferring the communication session within the residential gateway without routing the communication session through the service provider'"'"'s network and wherein the establishing comprises;

storing a native address of the second communication device in a memory as a temporary device address;

setting a session address in memory equal to the stored temporary device address; and

associating the temporary device address with the session address in memory.

22. The computer readable storage medium of claim 21, wherein the transferring further comprises:

setting the temporary device address in memory to a native address of the third communication device in response to receiving a device transfer request;

sending a copy of a session history stored in memory to the third communication device; and

routing data intended for the second device to the third device identified by temporary device address in memory.

23. A. method comprising:

establishing a communication session comprising data on a service provider'"'"'s network between a first communication device and a second communication device;

storing a native address of the second communication device in a memory as a temporary device address;

setting a session address in memory equal to the stored temporary device address;

associating the temporary device address with the session address in memory;

receiving a request to transfer the communication session comprising data from the second communication device to a third communication device, wherein the second and third communication devices each comprise at least one of a Universal Mobile Telecommunications System (UMTS) handset and a Digital Enhanced Cordless Telecommunications (DECT) handset;

setting the temporary device address in memory to a native address of the third communication device; and

routing, within a residential gateway, data from the communication session intended for the second device to the third device identified by temporary device address in memory.
