  • Publication number: 20130252595
    Abstract: A method of establishing a communications session for communication of data with respect to a telephony user device and at least one other user device in a data communications network. Communications are conducted with a server system. The communications comprise a client-server connection. Call party details of a telephone call are transmitted to the server system in the communications. The telephone call involves at least the telephony user device, as a first telephony user device involved in the call, and a second telephony user device involved in the call. The call party details including a first identity associated with the first telephony user device and a second identity associated with the second telephony user device.

  • Publication number: 20130230157
    Abstract: A method of establishing a communications session for communication of data with respect to at least two user devices in a data communications network. A client-server connection request is received from at least one of the at least two user devices. Call party details of a telephone call are received. The telephone call involves at least a first telephony user device and a second telephony user device. The call party details include a first identity associated with the first telephony user device and a second identity associated with the second telephony user device. At least one of the first and second identities comprises a telephone dialling number. A separate communications session is established on the basis of the first and second identities received in the call party details.

  • Publication number: 20130230158
    Abstract: A method of establishing a communications session for data with respect to at least two user devices in a packet switched communications network in parallel to a voice session via a circuit switched network. Call party details of a telephony call are received. The telephony call involves at least a first telephony user device and a second telephony user device. The call party details include a first identity associated with the first telephony user device and a second identity associated with the second telephony user device. A separate communications session is established on the basis of the first and second identities received in the call party details and depending on the capabilities of the user devices. The communications session is separate from the telephone call, for the communication of data to and/or from at least two user devices.

  • Publication number: 20130227058
    Abstract: Processing data in a communications system comprising a plurality of servers is provided. First data received from a communications device is directed to a given server in the plurality of servers. A server identifier identifying the given server is transmitted to the communications device. Subsequent data is received from the communications device. The subsequent data comprises the server identifier and a further parameter. The given server is selected on the basis of at least the server identifier and some of the subsequent data received from the communications device is directed to the given server. In the event of a need to redirect subsequent data to a server other than the given server, a different server is selected on the basis of at least the further parameter and further of the subsequent data received from the communications device is directed to the selected different server.

  • Publication number: 20130101106
    Abstract: A method of processing data in relation to a teleconference service in a telecommunications network is provided. The teleconference service is able to handle a multi-party teleconference for three or more teleconference participants. First, second and third teleconference participation identifiers are received from first, second and third teleconference participants respectively. The first, second and third teleconference participation identifiers are correlated to determine that the first, second and third teleconference participants are participants in a given multi-party teleconference. Data is transmitted for enabling the establishment of a data communications session which is established separately from the teleconference.
