Abstract

A method of operating a communications system such that connections supporting a communications session being run on a first terminal (1) may be diverted to a second terminal (2) such that the session may be coninued on the second terminal comprises the steps of creating a user profile on a server device (3), the user profile identifying a plurality of terminals (1,2), generating from the user profile a set of parameters defining a virtual terminal (12, 22), storing, as parameters of the virtual terminal, details of a current communications session (11) made using a first terminal, on instruction from one of the user terminals (1, 2), diverting the routing of a communications connection supporting the session from the first terminal (1) to a second terminal (2), and and transferring the details of the current session (11) to the second terminal for use in continuing the session. This process allows a user to continue a session on a second terminal if it becomes more convenient to do so, rather than having to start a new session and potentially losing any information obtained whilst using the first terminal.

Claims

1. A communications system arranged such that connections to a first terminal supporting a communications session on the first terminal may be diverted during the course of the session such that the session may be continued on a second terminal, the communications system comprising:

a server device for processing calls, means for creating a user profile on the server device, the user profile identifying a plurality of terminals,

means for generating from the user profile a set of parameters defining a virtual terminal

a store for parameters of the virtual terminal, said parameters being details of a current communications session made using a first terminal,

means for diverting, on instructions from a user device, the routing of a communications connection supporting the session from the first terminal to a second terminal,

means for transferring the details of the current session to the second terminal for use in continuing the session.

2. Apparatus according to claim 1, comprising means for storing information relating to each of the plurality of terminals, and means for adapting the details of the current communications session in accordance with the terminal to which the session is to be diverted on receipt of a diversion instruction.

3. Apparatus according to claim 2, comprising means for translation of a session into a data handling protocol suitable for the terminal.

4. A method of operating a communications system such that a connection to a first terminal supporting a communications session on the first terminal may be diverted during the course of the session such that the session may be continued on a second terminal, the method comprising the steps of

creating a user profile on a server device, the user profile identifying a plurality of terminals,

generating from the user profile a set of parameters defining a virtual terminal,

storing, as parameters of the virtual terminal, details of a current communications session made using a first terminal,

on instruction from the user, diverting the routing of a communications connection supporting the session from the first terminal to a second terminal, and

transferring the details of the current session to the second terminal for use in continuing the session.

5. A method according to claim 4, comprising the further steps of storing information relating to each of the plurality of terminals, and on receipt of a diversion instruction adapting the details of the current communications session in accordance with the terminal to which the session is to be diverted.

6. A method according to claim 5, wherein the session is translated into a data handling protocol suitable for the terminal.

7. A method according to claim 4, wherein the diversion of routing is initiated by an instruction transmitted from the second terminal to the server device.

8. A method according to claim 7, wherein the diversion of routing is initiated by an instruction transmitted from the first terminal to the second terminal, causing the second terminal to transmit an instruction to the server device.
