摘要： The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.

摘要： A method of enabling the management of handovers of voice calls from a Packet Switched, PS, access to a Circuit Switched, CS, access where the voice calls are established using an IP Multimedia Subsystem, IMS, network. The method comprises performing a first IMS registration of a user via said PS access including setting for the user in a Home Subscriber Server, HSS, of the user's home network, an identifier of a first access transfer control fu nction, which access transfer control function is responsible for anchoring user media sessions in an access transfer gateway of a serving network, and notifying a mobility function within said service network of the set identifier. A second or further IMS registration of the same user is then performed via said PS access, it being determined that said first IMS registration exists. As a consequence, the setting of an identifier of a second or further access transfer control function in the HSS for the user is prevented, whilst either the setting of the identifier of the first access transfer control function is maintained, or is replaced with an identifier of a service centralisation and continuity application server. The mobility function is notified of any change to the set identifier. In the event of a requirement to handover an ongoing voice call associated with said second or further IMS registration from said PS to said CS access, the identifier currently set in the HSS and identified to the mobility function is used to manage the handover.

摘要： A method and apparatus for transferring a session from a packet switched access network to a circuit switched access network. A Mobility Management Entity receives a service type indicator from a gateway node. The service type indicator indicates a type of service for the session, and is associated with bearers used for the session. The Mobility Management Entity subsequently receives, from an eNodeB, an indication that the session is to be transferred from the packet switched network to the circuit switched access network. The Mobility Management Entity determines the bearers associated with the session using the service type indicator, and initiates transfer of the session using those bearers. This ensures that the correct bearers are transferred regardless of whether or not identifiers such as QCI values have been ascribed to other types of service.

摘要： The present invention relates to a key management method to establish selective secret information in multiple disjoint groups, more specifically to a method of reducing the broadcast size in access hierarchies and localize and facilitate management in said access hierarchies. The key management method selects a number of subgroups. Each subgroup supports an instance of a key distribution method for receiving distributed key material, and is capable of computing a usage security key based on the distributed key material and predefined user group key material.

摘要： A method and apparatus for key management in a communication network. A Key Management Server (KMS) receives from a first device a request for a token associated with a user identity, the user identity being associated with a second device. The KMS then sends the requested token and a user key associated with the user to the first device. The KMS subsequently receives the token from the second device. A second device key is generated using the user key and a modifying parameter associated with the second device. The modifying parameter is available to the first device for generating the second device key. The second device key is then sent from the KMS to the second device. The second device key can be used by the second device to authenticate itself to the first device, or for the first device to secure communications to the second device.

摘要： A method of facilitating access to services of an IP Multimedia Subsystem,by users groups that require alternative handling in relation to the standard handling of IP Multimedia Subsystemusers. Functioning instructions are added to the user group s subscription maintained in the IP Multimedia Subsystem, instructing nodes in the IP Multimedia Subsystemto adapt their standard functioning for this specific group of users. The instructionsin a subscription of a specific user group, providea node of the IP Multimedia Subsystemthat does no longer need to be specific for certain types of users,but has a standard way of operation,that is modified by instructions for dedicated operation for only that specific user group. In further aspect embodiments are disclosed providing improved solutions for known problems of IP Multimedia Subsystems making use of functioning instructions included in the subscription.
