Communication System
First Claim
1. A method of controlling a communication session established in a telecommunications network between a first communication client of a plurality of communication clients on one or more communication devices associated with a first party and a communication device associated with a second party, said established communication session comprising at least a first communication session leg established between said first communication client and an intermediate node in said telecommunications network, the method comprising:
- detecting a loss in connectivity associated with the first communication session leg; and
in response to detecting said loss in connectivity, initiating set up of a second communication session leg between an intermediate node in said telecommunications network and at least a second communication client of said plurality of communication clients on one or more communication devices associated with the first party.

Abstract
A method of controlling a communication session is provided. The communication session is established in a telecommunications network between a first communication client of a plurality of communication clients on one or more communication devices associated with a first party and a communication device associated with a second party, the established communication session comprising at least a first communication session leg established between the first communication client and an intermediate node in the telecommunications network. The method includes detecting a loss in connectivity associated with the first communication session leg, and in response to detecting the loss in connectivity, initiating set up of a second communication session leg between an intermediate node in the telecommunications network and at least a second communication client of the plurality of communication clients on one or more communication devices associated with the first party.

1. A method of controlling a communication session established in a telecommunications network between a first communication client of a plurality of communication clients on one or more communication devices associated with a first party and a communication device associated with a second party, said established communication session comprising at least a first communication session leg established between said first communication client and an intermediate node in said telecommunications network, the method comprising:
-
detecting a loss in connectivity associated with the first communication session leg; and in response to detecting said loss in connectivity, initiating set up of a second communication session leg between an intermediate node in said telecommunications network and at least a second communication client of said plurality of communication clients on one or more communication devices associated with the first party. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. Apparatus for use in controlling a communication session established in a telecommunications network between a first communication client of a plurality of communication clients on one or more communication devices associated with a first party and a communication device associated with a second party, said established communication session comprising at least a first communication session leg established between said first communication client and an intermediate node in said telecommunications network, the apparatus comprising a processing system adapted to:
-
detect a loss in connectivity associated with the first communication session leg; and in response to detecting said loss in connectivity, initiate set up of a second communication session leg between an intermediate node in said telecommunications network and at least a second communication client of said plurality of communication clients on one or more communication devices associated with the first party.

22. A computer program product comprising a non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to perform a method of controlling a communication session established in a telecommunications network between a first communication client of a plurality of communication clients on one or more communication devices associated with a first party and a communication device associated with a second party, said established communication session comprising at least a first communication session leg established between said first communication client and an intermediate node in said telecommunications network, the method comprising:
-
detecting a loss in connectivity associated with the first communication session leg; and in response to detecting said loss in connectivity, initiating set up of a second communication session leg between an intermediate node in said telecommunications network and at least a second communication client of said plurality of communication clients on one or more communication devices associated with the first party.

23. A method of controlling a communication session established in a telecommunications network between a first communication client on a first communication device associated with a first party and a second communication device associated with a second party, said established communication session comprising at least a first communication session leg established between said first communication client and a node in said telecommunications network, the method comprising, at said first communication device:
-
detecting a loss in connectivity associated with the first communication session leg; receiving a subsequent communication session setup request directed to a second communication client on said first communication device; determining that said subsequent communication session setup request relates to said established communication session; and in response to determining that said subsequent communication session setup request relates to said established communication session, transmitting a communication session acceptance message from said second communication client.
