20100074154 | Accessing a Communications Network - A method and node in a communication network for facilitating access by a client terminal to an IMS service from a non-Session Initiation Protocol (non-SIP) compliant access network such as a circuit-switched network. The node receives a request from the client terminal and in response, allocates to the terminal, a Terminal Adapter from a plurality of Terminal Adapters. The node then sends a message to the client terminal reporting the address of the allocated Terminal Adapter. | 03-25-2010 |
20100088374 | Supplementary Services in Communication Networks - A method and application server for handling a supplementary services message in a communication network. A subscriber's Home Location Register (HLR) sends an Interrogation marker to the subscriber's Mobile-services Switching Center/Visitor Location Register (MSC/VLR) instructing the MSC/VLR to forward all supplementary services messages from the subscriber to the HLR. When the subscriber's user terminal sends a supplementary services message to the MSC/VLR requesting a supplementary service, the MSC/VLR forwards the message to the subscriber's HLR. The HLR retrieves an address of an IP Multimedia Application Server associated with the subscriber, and sends the supplementary services message to the addressed Application Server for handling the supplementary services request. | 04-08-2010 |
20100118861 | Inter-Working Between a Packet-Switched Domain and a Circuit-Switched Domain - The present invention proposes a solution for providing packet-switched services to a user, even in case the user is accessibly only via a circuit-switched access. For this purpose it is proposed to force the user to report changes in the reachability status and to keep the user's registration alive in a packet-switched domain as long as the user is reachable. A packet-switched adapter located between the circuit-switched domain and a packet-switched domain aligns the registration status of the user in the packet-switched domain to the reachability status and performs a registration procedure depending on the outcome of the alignments. The registration procedure might be in detail either a registration or a re-registration or a de-registration procedure. | 05-13-2010 |
20100182998 | Access Domain Selection In A Communications Network - A method and apparatus for managing access domain selection for a user device accessing an IP Multimedia Subsystem (IMS) network. A Call Session Control Function (CSCF) in the IMS network stores an access domain indicator associated with a user s contact address. The access domain indicator is associated with the user s contact address when the user registers with the IMS network. The CSCF sends the access domain indicator to an Access Domain Selection (ADS) function in the IMS network, the access domain indicator to be used by the ADS function in selecting an access domain. This allows the ADS function to select the correct access domain to use when sending messages to the user device. | 07-22-2010 |
20100246523 | METHOD AND APPARATUS FOR CORRELATING SIGNALLING IN A COMMUNICATIONS NETWORK - A node in an IMS network receives circuit switched signalling relating to a communication session sent from a terminal over a circuit switched access network, and also receives packet switched signalling relating to the communication session sent from the terminal over a packet switched access network. The packet switched signalling comprises an identifier, and the node uses the identifier to correlate the circuit switched signalling with the packet switched signalling. This allows terminals using ICS to send signalling over both packet switched and circuit switched access networks, and a receiving node to correlate those signals. | 09-30-2010 |
20110023065 | METHOD FOR PROVIDING A TELEVISION ELECTRONIC GUIDE - A method and apparatus for providing a packet switched television guide such as an Electronic Program Guide or an Electronic Service Guide to a user. An Application Server receives and stores preferences relating to a packet switched television guide. When the Application Server subsequently receives a new or updated packet switched television guide from a packet switched television Guide Application Server, the Application Server filters elements of the packet switched television guide according to the preferences to remove information not relevant to a user associated with the preferences. The filtered packet switched television guide is then sent to the user. In this way, only relevant information is sent, which can reduce the bandwidth required in sending packet switched television guides, the frequency at which packet switched television guide updates need to be sent, and also the processing required by the user's receiving equipment in filtering out irrelevant information from the packet switched television guide. | 01-27-2011 |
20120246289 | Control Entity and Method for Setting up a Session in a Communications Network, Subscriber Database and Communications Network - Control entity and method for setting up a session in a communications network, subscriber database, and communications network. The control entity advantageously has or has access to memory for storing information, and typically includes an input device for receiving a request to set up a session in the communications network, a processor unit for processing the request, and an output device for sending messages. The processor unit is arranged to determine if the request comprises a valid Communication Service Identifier (CSI) the CSI identifying the type of communication service of the session that is to be established over the communications network. And if the request does not comprise a valid Communication Service Identifier, to execute a default CSI procedure using default CSI information stored in the memory. | 09-27-2012 |

20100198980 | Method of transmitting data in a communication system - A method and system for transmitting data over a channel of a network. The method comprises: receiving data at a first node; encoding a first portion of the data at a first bit rate to generate a first encoded data stream; monitoring an indication of the capacity of the channel; transmitting to the second node a padded data stream via the channel, wherein padding bits are added to the first encoded data stream, in dependence on the indication of the capacity of the channel, to generate the padded data stream; determining if transmitting the padded data stream exceeds the capacity of the channel; and encoding a second portion of the data at a higher bit rate than the first bit rate, to generate a second encoded data stream for transmission over the channel, if it is determined that transmitting the padded data stream does not exceed the channel's capacity. | 08-05-2010 |
20110038362 | Controlling multi-party communications - A first user terminal, host terminal, method and program. The first terminal comprises: a transceiver for communicating with a plurality of other user terminals over a communication network; and communications processing apparatus, coupled to the transceiver, and arranged to participate in a call with a selected number of the other user terminals via the transceiver and communication network, the call including transmission of a voice signal from the first user terminal. The communications processing apparatus is operable in a mode whereby it temporarily discontinues transmission of the voice signal in response to detecting less than a predetermined level of activity on said voice signal, and the communications processing apparatus is further configured to selectively enable that mode in dependence on the selected number of other user terminals in the call. | 02-17-2011 |
