    摘要: A system, method, and nodes for managing shared security keys between a User Equipment, UE, an authentication node such as an SCF/NAF, and a service node such as a BM-SC or AS. The SCF/NAF allocates to each BM-SC, a different SCF/NAF identifier such as a fully qualified domain name, FQDN, from the FQDN space the SCF/NAF administers. The SCF/NAF then locally associates these allocated FQDNs with the connected BM-SCs and with different services. The network sends the correct FQDN to the UE in a service description for a desired service, and the UE is able to derive a security key using the FQDN. When the UE requests the desired service, the SCF/NAF is able to associate the service identifier with the correct FQDN and an associated BM-SC. The SCF/NAF uses the FQDN to obtain the security key from a bootstrapping server and sends it to the associated BM-SC. As a result, the UE and the associated BM-SC share a specific security key.

    摘要: A method is provided for use by a user terminal (20) operating an IP-based multimedia broadcast/multicast service. The method comprises storing (S3) information relating to user service registrations performed (S2) using an IP connection such as a Packet Data Protocol, PDP, context established to enable connectivity between the user terminal (20) and a service node (40) for the broadcast/multicast service. The information is of a type to enable re-registration (S7) of at least some of any of the user services affected by a loss of the IP connection. In one embodiment, the multimedia broadcast/multicast service is a 3GPP Multimedia Broadcast/Multicast Service, MBMS, the user terminal (20) is a User Equipment, UE, and the service node (40) is a Broadcast/Multicast Service Center, BM-SC. In another embodiment, the multimedia broadcast/multicast service is an Open Mobile Alliance Broadcast, OMA BCAST, service, the user terminal (20) is a Terminal, and the service node (40) is an OMA BCAST Subscription Management, BSM, node.

    摘要: Methods for cryptographic synchronization of data packets. A roll-over counter (ROC) value is periodically appended to and transmitted with a data packet when a function of the packet sequence number equals a predetermined value. The ROC effectively synchronizes the cryptographic transformation of the data packets. Although the disclosed methods are generally applicable to many transmission protocols, they are particularly adaptable for use in systems wherein the data packets are transmitted to a receiver using the Secure Real-Time Transport Protocol (SRTP) as defined in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3711.

    摘要: 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.

    摘要: 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.
