Abstract: The present invention relates to an arrangement and method for performing a push operation in a communication system. Also, the present invention concerns an involved gateway entity and push destination entity. The arrangement comprises a receiver device, at a gateway entity of the communication system, configured to receive a request to perform a push operation towards a push destination entity, and comprises a connecting session device, at the gateway entity and the push destination entity. The connecting session device comprises setup means configured to setup a connecting session invoking a messaging session for delivering content to be pushed in the push operation towards the push destination entity.

Abstract: A method provides control of push operations in a communication system. The method includes requesting capabilities information associated with a communication device. The capabilities information includes an indication of at least one push method supported by the communication device. The method also receives the capabilities information. The method also decides a way to handle a push operation towards the communication device based on the capabilities information. The capabilities information may be stored as a part of presence information relating to a user of the communication device.

Abstract: A method establishes a push session in a communication system. The method includes receiving a session invitation having a description of a push protocol over a transport protocol for establishing a push session. The method also includes setting up a transport bearer in accordance with the transport protocol. The method also includes using the transport bearer for a push session in accordance with the push protocol. A push gateway is configured to receive a submission to start a push operation towards the communication device and to transmit, based on the submission, the session invitation including the description to the communication device. A communication device is configured to execute the method.

Abstract: A method of transmitting signalling information in a telecommunications network between peer user/application parts. Signalling information is transferred from a first user/application part to a Message Transfer Part (MTP) level 3, the information including a destination signalling point identifier identifying the signalling point at which the peer user/application part is located. The MTP level 3 determines from the destination signalling point identifier, a destination address suitable for conveying the signalling information to the destination signalling point. In the event that the destination address is an Internet Protocol (IP) address and Port number, the signalling information and the determined IP address and port number are transferred to an IP part for transmission over an IP network to the destination signalling point.

Abstract: A method provides callback services in a communications system to a first party from a second party. The method includes supplying the second party with a telephone number of the first party in a first format. The method also includes selecting a numbering plan out of plurality of numbering plans based on at least one of the country and network where the second party is located. The method also includes converting the telephone number from the first format to a second format using the selected numbering plan.

Abstract: A method of transmitting signalling information in a Public Land Mobile Network (PLMN) between a pair of peer application part. An adaptation layer is interposed between the SCCP of an SS7 network and a TCP/IP part to allow signalling data to be transmitted to and from the SCCP via an IP based network. The adaptation layer provides for translation between Destination Point Codes (DPCs) and or global titles, used as addresses in the SS7 network, and IP addresses/port numbers for use in the IP network. The adaptation layer also provides for formatting of SCCP messages suitable for processing by the TCP/IP layers, and also for formatting signalling information flowing in the reverse direction.

Abstract: A method of setting up a session between peer user terminals of a communication system, said session extending at least in part across a circuit switched access network. The method comprises transporting signalling to initiate said session between at least one of the peer user terminals and said communication system via an IP based packet switched access network using a call control protocol which is also used for setting up end-to-end packet switched sessions, and subsequently establishing said session based upon said signalling.

Abstract: A method of routing signalling information at a signalling point of a telecommunications network. A Global Title Routing Case (GTRC) table is provided for mapping Global Titles to GTRCs, where each GTRC is allocated a primary and secondary destination signalling point. At least one peak time period is predefined, and said primary and secondary destination signalling points are swapped during said peak period to allow for load sharing during this period. For a signalling transfer request received at the signalling point, the Global Title associated with the request is mapped to a GTRC using the GTRC table, and the destination signalling point is determined in dependence upon the primary and secondary destination signalling points allocated to the mapped GTRC and signalling point availability, and, the time at which the request is received.

Abstract: Method for transmitting signaling information in a telecommunications network between a pair of application parts, the method comprising the steps of: generating signaling information at a first application part, including addressing information associated with the second application part, passing the signaling Information from the application part to a Transaction Capabilities Application Part (TCAP); passing the signaling information from the TCAP to an adaptation layer arranged to determine an IP address and port number associated with the addressing information; passing the signaling Information and the IP address and port number to an Internet Protocol (IP) part and transmitting the signaling information over an IP network to the destination IP address in one or more IP datagrams; decapsulating the signaling information at the destination associated with the IP address and at an adaptation layer identified by the port number; and routing the signaling information to the second application part.

Abstract: A method of transferring signalling information from an SS7 network to an IP network using SIP signalling through a Media Gateway Controller (MGC), the method comprising receiving an Initial Address Message (IAM) from the circuit switched network at the MGC, and generating a SIP set-up message at the MGC, wherein the SIP set-up message includes a loop protection field containing a hop counter or redirection counter in the IAM.

Abstract: A method of enabling a terminal 1,2 coupled to a GSTN 10 to join an Internet based presence service facilitated by a presence server 6. The method comprises establishing a telephone connection between said terminal 1,2 and an intermediate server 4 via the GSTN 10, as a result of said connection, establishing a proxy entity corresponding to said terminal 1,2 at said intermediate server 4 and registering the proxy entity with the presence server 6 via the Internet, and exchanging presence service messages between the presence server 6 and the proxy entity at the intermediate server 4 via the Internet and between the proxy entity and said terminal 1,2 via the GSTN network 10.
