Abstract: The invention is about a method in a network node (11; 12; 50) of an Internet Protocol Multimedia System, IMS, for establishing an additional session between a local user equipment, UE (10; 60), which is registered in the IMS, and a remote UE (20) which public identity is unknown to the local UE (10; 60), wherein a first session is established between the local UE (10; 60) and the remote UE (20), comprising the steps of: —storing a relation between the public identity of the remote UE (20) and a further identity which is provided to the local UE (10; 60); —receiving a request for establishing an additional session, comprising the further identity of the remote UE (20); —replacing the further identity of the remote UE (20) with the public identity of the remote UE (20) and forwarding the request towards the remote UE (20). The invention is further about a network node (11; 12; 50) and a UE (10; 60) which are adapted to perform the method.

Abstract: A data handling unit and a method therein for handling information regarding call events in a Multimedia Telephony Service, MMTel, network are provided for enabling call logging, wherein a SIP Message comprising call log information referring to a call event is generated for the call event and sent to a storage server. The method comprises receiving information on at least one call event, generating a SIP Message comprising call log information referring to the call event, and sending the generated SIP Message towards a storage server.

Abstract: A telecommunication system and method for controlling the establishment of payload connections through media gateways. The system receives and aggregates control orders from a plurality of telecommunication nodes such as media gateway controllers. The system uses knowledge of resources in the network to optimize the path of the payload connection. The system also sends control orders to a given media gateway in order to establish the payload connection. The system may be connected to a plurality of other instances of the same type of system in a hierarchical manner.

Abstract: A method and capability manager for supporting provision of capabilities of a first user terminal to a second user terminal. Filtering rules have been pre-configured in the capability manager for the first user terminal to control exposure of capabilities. When the capability manager receives a capability message issued by the first user terminal, filtering rules are applied on the capabilities in the capability message, to modify the capability message by omitting at least one of the capabilities based on the filtering rules. The modified capability message is then forwarded towards the second user terminal. Thereby, options for communication will be indicated at the second terminal in accordance with the capabilities in the modified capability message, i.e. in a way that can be controlled by the user.

Abstract: A hybrid arrangement allows an existing circuit switched telephony network to be deployed on a packet switched network. The circuit switched underlying transport network is replaced with that of an IP based package switched network, while the circuit switched infrastructure, such as terminals, telephone exchanges and the like are retained. Both a subscriber and a local telephone exchange are connected to, and separated by, an IP based packet switched network, such as the Internet. Signalling between the subscriber and exchange are effected using a standard user to network protocol, such as V5.1 for PSTN and ISDN BRI or DSS1 for ISDN PRI. This standard user network is overlaid on an IP based network protocol, such as TCP or UDP on IP.

Abstract: A mobile telecommunications network is proposed with an access network portion (10) having several base station systems (101) that can communicate with a core network portion (20). The base station systems are adapted to communicate with mobile terminals (1) over a licensed public mobile network air interface and with the core network portion over a predetermined network interface. The network also includes at least one local base station system (104, 105, 106) that is arranged to communicate with the core network portion over the predetermined network interface. This local base station system is further adapted to communicate with mobile terminals over an unlicensed radio interface (11). The local base station system makes use of an existing fixed network based on IP.
