Abstract: According to an aspect of the present disclosure, a method is disclosed for a SIPIMR node to withdraw from a SIP session set-up loop by replying a redirect message to the SIP Invite sending node. The redirect message contains information for setting up alternative SIP session, said information being available in the SIP Invite receiving node. This information is usable by the SIPIMS node for establishing an alternative SIP session as well as information needed by other nodes and applications further on in the SIP session set-up loop. The SIPIMS node is specially adapted to retrieve the information from the redirect message for establishing a new SIP session based on and containing the information from the redirect message. Several implementations are given for use in an IP Multimedia Subsystem of a telecommunication network.

Abstract: The system includes a device of a plurality of devices and a network entity for connecting the device to a communications network. The device is arranged for attempting to access the network while providing an identification of the device to the network entity. The network entity is arranged for receiving the access attempt from the device, and determining the identification of the device. The network entity determines an identification of a subscription associated with the device from a first database of the system. The network determines whether the identified subscription has the device associated therewith in a second database. The network entity allows the device to connect to the network entity or prevents the device from connecting to the communications network depending on the above determinations.

Abstract: Combinational networks provide simultaneous connectivity via networks of different network type between user equipment. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introduction of an identifier denoted as Combinational Call Indicator (CCI). This CCI identifier in combination with the known Calling Line Identity (CLI) identifier enables user equipment and other and network entities to perform a correlation check between ongoing, or to be established, CScalls and PS-sessions. A user equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier during the communication session setup towards the receiving user equipment or network entity, which is enabled to check whether the last received communication session is correlated to the earlier established session due to the presence of the CCI identifier.

Abstract: An access node cooperates with a primary modem-router in a packet switched network. The access node comprises communication hardware configured to enable communication through the network by sending and receiving data packets, and encapsulates the data packets in a tunnelling data protocol for sending the data packets to the primary modem-router using a data communication tunnel through a further modem-router. The communication hardware is also configured to retrieve, from the tunnelling data protocol, data packets received from the primary modem-router.

Abstract: A first end node obtains trace information in a packet switched network. The first end node sends a request message for setting up a test call towards a second end node. The request message includes a first request for collecting trace information. The second end node sends a first response message, to the first end node, that includes a trace request and trace information. The first response message is routed between the second and first end nodes via at least a first intermediate node that adds additional trace information relating to the first intermediate node to the trace information of the first response message. The first end node receives the first response message, which includes the additional trace information added by the first intermediate node.

Abstract: Combinational networks may provide simultaneous connectivity over networks of different type between User Equipment of an A-party and B-party. A communication session, comprising a circuit switched call and one or more packet switched sessions, may be deployed simultaneously over different network types, in relation to the same User Equipment. The circuit switched call and the packet switched session may be correlated. As to retrieve the packet switched address of a circuit switched call partner, a retrieval for a packet switched network address is initialized by means of a circuit switched protocol over a circuit switched network. The address retrieval request is directed to the call partner or a network node that accomplishes the network address request.
