Abstract: A method (100), performed by a first network node in a communication network, is disclosed. The first network node is connected to a second network node of the communication network via an interface implementing a GPRS Tunnelling Protocol (GTP). The method comprises selecting a user data packet for transmission to the second network node (110) and identifying information about the user data packet which impacts how the user data packet should be routed over the interface (120). The method further comprises encoding the identified information into a User Datagram Protocol (UDP) header of the user data packet (130) and forwarding the user data packet to the interface for transmission to the second network node (140). Another method (300) is disclosed, performed by a node in a Mobile Transport Network, the Mobile Transport Network providing a GTP based interface between a first network node of a communication network and a second network node of the communication network.

Abstract: Embodiments of the invention include a method for providing UE session resilience performed in a first PDN-GW that is coupled to a second PDN-GW, which are both in a PDN-GW pool. The method provides UE session resilience by allowing the first PDN-GW to provide connectivity for UE sessions previously serviced by the second PDN-GW after the second PDN-GW becomes non-operational. The first PDN-GW recognizes that the second PDN-GW failed and then activates a plurality of standby UE sessions. Each standby UE session is a backup UE session corresponding to a previously active UE session serviced on the second PDN-GW. Each standby UE session is associated with a UE device and a network resource identifier of an APN slice. The first PDN-GW transmits a message to a SGW that is servicing the UE sessions that indicates that the SGW should direct traffic previously bound for the second PDN-GW to the first PDN-GW.

Abstract: A node (115, 210) for a mobile network (100), arranged to forward control plane signaling to and from an end user (140, 216) in the system (100) to other nodes in the system (100) and also being arranged to keep track of a state of the end user (140, 216). The node (115, 210) is arranged to use a so called VRRP protocol, Virtual Router Redundancy Protocol to monitor the function of a second node (120, 212) in the system, a so called “peer node” to the node (115, 210) itself and to have its own function be monitored by a VRRP of the peer node (120, 212). The node (115, 210) is also arranged to use a second protocol for transferring information on a state of the end user (140, 216) to the peer node. A node (120, 212) for receiving such information is also disclosed.

Abstract: A server for controlling user MTC devices. The server ascertains if a user MTC device has an IP connection to a cellular access network, and if so, sends a message to trigger the user MTC device to initiate an application defined in the message. If a user MTC device does not have an IP connection, the server ascertains if the user MTC device is a mobile or a stationary user MTC device, and for a stationary user MTC device, the server sends a message to the cellular access network to trigger the user MTC device to initiate an IP connection, and for a mobile user MTC device, waits until the user MTC device has an IP connection, and for both kinds of user MTC devices, when the user MTC device has an IP connection, transmits a message to the user MTC device to initiate an application defined in the message.

Abstract: The present invention relates to a method for enabling IP multimedia system, IMS, signalling traffic in a Policy and Charging Control, PCC, environment between a user equipment (21), UE, and a proxy call session control function (16), P-CSCF, device. The method comprises the following steps: 1. The UE (21) requests (10) in a gateway (17), GW, at least one P-CSCF device address for IMS signalling traffic between the UE (21) and the P-CSCF device (16). 2. The GW (17) sends (11) a request for a policy decision for the IMS signalling traffic to a first policy control node (22,23), PCN. 3. The first PCN (22,23) responds (12) to PCN. the GW (17) with policy information defining the policy decision for the IMS signalling traffic, 4. The GW (17) installs (13) the policy information and provides the P-CSCF device address/-es assigned to said information to the UE (21). What particularly characterizes the method is a step where the first PCN (22, 23) defines (14) the policy information for the IMS signalling traffic.

Abstract: The present invention relates to a solution for providing access to services and media content located in a local area network, e.g. a home network, via a web interface controlled by a universal plug and play (UPnP) control point device. The UPnP device is arranged to discover the services and media content available in the local area network and present this on the web interface for access from a public area network. The UPnP device may further be arranged to authenticate the user in order to secure the content and services from unauthorized access.

Abstract: The invention discloses a Home Virtual Private Network server (250), a Home VPN server, for use in a communications operator network (120), which network (120) can communicate with a subscriber network (130), and in which operator network a first protocol on a first level is used. The subscriber network (130) can accommodate at least one subscriber with one subscriber device (131-135) and a communications device (140) which can connect the subscriber to the operator network (120). The Home VPN server (250) comprises functions for: translating IP-addresses and port numbers of IP-packets which are sent between the operator network and the subscriber network, assigning individual IP-addresses to devices in the subscriber network, routing IP-traffic from the operator network to devices in the subscriber network, to which functions the subscriber can connect via said communications device (140) in order to utilize his network (130) as a Home VPN.

Abstract: A communications network and method is provided for framing point-to-point frame structures to minimize the overhead that consumes the bandwidth of a radio air interface located between a mobile station and a packet switched network. More specifically, the mobile terminal utilizes a serial interface and point-to-point protocol to connect to a data terminal, and a communication protocol and air interface to connect to the packet switched network. The mobile terminal inserts a first predetermined set of fields (overhead) onto a first frame structure (data) received from the packet switched network, and then forwards the inserted first frame structure (data and overhead) to the data terminal equipment. In addition, the mobile terminal removes a second predetermined set of fields (overhead) from a second frame structure (data and overhead) received from the data terminal, and then forwards the stripped second frame structure (data) to the packet switched network.
