Abstract: Method and arrangement for supporting connectivity of a wireless device to a network infrastructure. An infrastructure provider associates a set of device identification numbers to a first radio access provider in a subscription database of the infrastructure provider. The infrastructure provider also sets the first radio access provider as a preferred roaming partner in a SIM that comprises a subscriber identifier with a network identifier of the infrastructure provider. The SIM is provided for use in the device, to enable access to the network infrastructure over a radio access network of the first radio access provider based on the subscriber identifier and the preferred roaming partner in the SIM.

Abstract: A method and apparatus for handling data between a radio network and a service network, the data comprising Network Aware data. A gateway node in a mobile core network receives a message from the radio network. It then determines whether the message comprises Network Aware data. If it does, then the message is routed to a Packet Data Network Gateway node configured to handle Network Aware data. If it doesn't, then the message is routed to a Packet Data Network Gateway node for message handling. This ensures that non-Network Aware data is handled using regular message handling, and Network Aware data is handled by nodes configured to handle Network Aware data.

Abstract: The invention includes a method of providing media data of a SIP-based Auxiliary Service from an Auxiliary Application Server, AS, to a recipient peer of an established communication exchange between peers. The method includes issuing an invocation to the Auxiliary AS, the invocation including an indication of the recipient peer of the Auxiliary Service. The Auxiliary Service media data is prepared and sent to the recipient together with a correlation ID identifying the established communication exchange, and an Application Classmark identifying the auxiliary service.

Abstract: A method for providing switching of a media session transmitted from a content server to a user equipment from a multicast to a unicast bearer. A preparation trigger recognised by the user equipment triggers a preparation phase wherein an application server prepares for an upcoming switch by re-configuring the media session and by providing the re-configuration data to the user equipment. Subsequent to the preparation phase, a second trigger triggers a release phase, wherein the multicast bearer is released, and the media session is resumed by the unicast bearer.

Abstract: Various techniques for routing a request message, which requests a service requiring a data operation on data which is stored in a data backend system, are discussed. The request message is received by a first application front end entity of an application layer. Based on the received request message, a data operation message is sent from the first application front end entity to a first data repository of the data backend system. The first data repository returns routing information to the first application front end entity, which enables the first application front end entity to route the request message to a second application front end entity of the application layer. The second application front end entity communicates with a given data repository which stores the data.

Abstract: Systems and methods for publishing presence information can be performed to reduce the amount of signaling associated with presence publication. A method for publishing presence service information to a presence server includes: receiving, at a registrar node, a session initiation protocol (SIP) message originated by a user equipment (UE) over the air interface; and transmitting a third party register message based upon the received SIP message, from the registrar node, toward a presence server using network signaling, wherein the third party register message includes at least one of information associated with the user of the UE, capabilities of the UE and presence related services offered by the UE.

Abstract: According to a first aspect of the present invention there is provided a method of providing interactive IP Television to a user terminal 1 over an IP Multimedia Subsystem 2. The method comprises, at a content server 3, sending the IP Television content and an interactive object to the user terminal 1 via the IP Multimedia Subsystem 2. At the user terminal 1, displaying graphical components of the interactive object together with the IP Television content, accepting user input to the interactive object and sending the input to an evaluation server 4 via the IP Multimedia Subsystem 2. At the evaluation server 4, comparing the user input with answer information associated with the interactive object and sending a result of the comparison to the user terminal 1 via the IP Multimedia Subsystem 2.

Abstract: A method for providing switching of a media session transmitted from server to a user equipment from a multicast to a cast bearer. A preparation trigger recognised by the user equipment triggers a preparation phase where in an application server prepares for an up-coming switch by re-configuring the media session and by providing the re-configuration data to the user equipment. Subsequent to the preparation phase, a second trigger triggers a release phase, wherein the multicast bearer is released, and the media session is resumed by the unicast bearer.

Abstract: Control entity and method for setting up a session in a communications network, subscriber database and communications network The invention relates to a control entity for setting up a session in a communications network, comprising 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 control entity further comprising or having access to a memory for storing information. The processor unit is arranged to determine if the request comprises a valid Communication Service Identifier, CSI, the Communication Service Identifier 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.

Abstract: An IMS-enabled control channel for an IPTV service is provided by receiving at a Serving Call/State Control Function (S-CSCF) a Session Initiation Protocol (SIP) REGISTER message, the SIP REGISTER message identifying the originating user, receiving at the originating user a response from the S-CSCF indicating that the originating user has been authorised, and sending a SIP INVITE message from the S-CSCF to establish an open channel connection with a selected IPTV Application Server (AS). This open channel connection can then be used for the transmission of control messages, such as for starting play, starting recording, stopping play, etc., between the STB and the IPTV applications server, as well as for the delivery of personalized content, such as advertisements, voting responses, personalized voting triggers and targeted interactive events. By maintaining an open control channel with the IPTV AS, this offers a substantial reduction in the setup delay times for different applications.

Abstract: An apparatus and method for indicating the IP Multimedia Subsystem (IMS) services to which a Session Initiation Protocol (SIP) message relates. One or more communication service identifiers are added to the SIP message as a Feature Tag.

The XML Document Manager Server function is enabled by a database component for storing at least one XML document and a logic component for causing at least one operation to be performed on one or more of the at least one XML documents. In the method, the logic component is provided by a first network entity (60-1), with which the XML Document Manager Client (2-1) communicates directly or indirectly to receive the XML Document Manager Server function, and the database component is provided by a second network entity (70) different to the first network entity (60-1).

Abstract: A method of distributing application server addresses in an IP Multimedia Subsystem. Upon allocation of an application server to a subscriber, the allocated or another application server sends at least one application server address to a Home Subscriber Server (HSS). The HSS stores the address(es) in association with the subscriber identity and sends the address(es) to a Serving Call/Session State Control Function (S-CSCF) allocated to the subscriber. The S-CSCF caches the address(es) in association with the subscriber identity and uses the address(es) to send subscriber-related messages to the allocated application server.
