    Abstract: P433622015-04-14 16:44 33 PROTECTING WLCP MESSAGE EXCHANGE BETWEEN TWAG AND UE Abstract A method of protecting WLAN Control Protocol (WLCP) message exchange between a Trusted WLAN Access Gateway(TWAG)(112)of a Trusted WLAN Access Network(TWAN)(110)and a User Equipment (UE)(101)are provided. The method comprises deriving, byan Authentication, Authorization, and Accounting, (AAA)Server(103)of an Evolved Packet Core (EPC)network which is interfaced with the TWAN, and bythe UE, a Master Session Key(MSK)and an Extended MSK(EMSK), sending, from the AAA Server to a Trusted WLAN AAA Proxy(TWAP)(113) of the TWAN and an Access Point(AP)(111)of the TWAN, the MSK or a key derived from at least the MSK, andderiving, by the TWAN or by the AAA Server, and by the UE, from the MSK, the EMSK, or the key derived from at least the MSK or the EMSK, a key for protecting the WLCP message exchange.Corresponding devices, computer programs, and computer program products are further provided.

    Abstract: Plural communication connections are established between an external network and subscriber units by way of a an access network. The subscriber unit connection is supported by plural nodes. When a failure is detected in a node, those subscriber unit connections affected by that failure are identified. A message identifying those subscriber unit connections affected by the failure is sent to one or more other nodes. Affected subscriber unit connections identified in the message are released. Those unaffected connections not included in the message are maintained.

    Abstract: A method of authenticating a request for session keys sent from a Network Authentication Function of a visited network to a Bootstrapping Server Function of a home network in respect of User Equipment, UE, the request comprising a transaction identifier. The method comprises, at the Bootstrapping Server Function, comparing a UE identification part of the transaction identifier with a value generated by applying a one-way function to an Authentication and Key Agreement key previously agreed between the UE and the Bootstrapping Server Function as part of an Authentication and Key Agreement procedure, and if the values agree, progressing the request by sending appropriate session keys to the Network Authentication Function, otherwise denying the request.

    Abstract: The present invention relates to a method of recovering from a processor fault in a mobile communication network node provided with a plurality of processors. In use, connections are established between the network node and mobile stations for packet data communication between the network node and the mobile station. The connections are classified into priority order on basis of predefined classifying parameters. Working condition of at least one of the processors of the network node is monitored, and in case of detecting a processor fault, user plane connections are relocated within the network node from the faulted processor to another processor in accordance with the classified priority order of the connections. The invention relates further to a network node.
