Abstract

A method (100) for session transfer mechanism between communication devices. The method (100) comprises the steps of triggering a session transfer (102) on an first device having an active session with a corresponding device, identifying a second device (104) from a plurality of devices for the session transfer, transferring the active session (106) transpiring between the first device and the corresponding device to between the second device and the corresponding device, and reclaiming the active session (108) transpiring between the second device and the corresponding device if a session reclaiming is triggered on the first device.

Claims

1. A method (100) for session transfer mechanism, the method comprising steps of:

triggering a session transfer (102) on a first device having an active session with a corresponding device;

identifying a second device (104) from a plurality of devices for the session transfer;

transferring the active session (106) transpiring between the first device and the corresponding device to between the second device and the corresponding device; and

reclaiming the active session (108) transpiring between the second device and the corresponding device if a session reclaiming is triggered on the first device.

2. The method according the claim 1, wherein the first device, the corresponding device and the second device comprises a mobile device or an immobile device.

3. The method according the claim 1, wherein triggering the session transfer (102) comprises the steps of:

depressing a transfer button (202) on the first device; and

sending a location information (204) of the first device to a location server.

4. The method according the claims 1 and 3, wherein identifying the second device (104) comprises the steps of:

storing in the location server, a location information of each device of the plurality of devices;

calculating in the location server (206), a distance information between the first device and each device of the plurality of devices;

identifying in the location server, the second device from the plurality of devices having a closest distance to the first device; and

sending an Uniform Resource Identifier of the second device (208) from the location server to the first device.

5. The method according the claims 1 and 4, wherein transferring the active session (106) comprises the steps of:

SIP REFER handshaking (210) between the first device and the corresponding device, wherein the SIP REFER handshaking comprises sending the Uniform Resource Identifier of the second device from the first device to the corresponding device; and

SIP INVITE handshaking (212) between the corresponding device and the second device.

6. The method according the claim 1, wherein reclaiming the active session (108) comprises the steps of:

triggering a session reclaim on the first device; and

reclaiming the active session transpiring between the second device and the corresponding device to between the first device and the corresponding device.

7. The method according the claim 6, wherein triggering a session reclaim comprises the steps of:

depressing a reclaim button (302) on the first device; and

SIP INVITE handshaking (304) between the first device and the second device, wherein the SIP INVITE comprises sending a session identification and a session reclaim message from the first device to the second device.

8. The method according the claims 4 and 6, wherein reclaiming the active session (108) comprises the steps of:

SIP REFER handshaking (306) between the first device and the corresponding device, wherein the SIP REFER handshaking comprises sending the Uniform Resource Identifier of the first device from the second device to the corresponding device; and

SIP INVITE handshaking (308) between the corresponding device and the first device.

9. The method according the claim 3, wherein the location server comprises a SIP server.

10. The method according the claims 1 and 9, wherein identifying the second device (104) comprises the steps of:

storing in the SIP server, a location information of each device of the plurality of devices;

calculating in the SIP server (406) using a customized process, a distance information between the first device and each device of the plurality of devices;

identifying in the SIP server, the second device from the plurality of devices having a closest distance to the first device,

sending an Uniform Resource Identifier of the second device (408) from the SIP server to the corresponding device; and

receiving a cascaded acknowledgement (410) from the corresponding node to the SIP server to the first device.

11. The method according the claims 1 and 9, wherein transferring the active session (106) comprises SIP INVITE handshaking (412) between the corresponding device and the second device.
