摘要： A method for re-establishing a Radio Resource Control, RRC, connection between a User Equipment (1), UE, and a target evolved NodeB (3), target eNB, the method being performed by the UE (1) and comprising:
receiving (S100) an RRC Connection Reestablishment message from the target eNB (3), the RRC Connection Reestablishment message including a downlink, DL, authentication token which has been generated by a Mobility Management Entity (4) and has had a Non Access Stratum integrity key and a freshness parameter as input; and
authenticating (S110) the received DL authentication token.
Disclosed are also an UE, a target eNB and a Mobility Management Entity as well as methods related thereto.

摘要： A wireless device (16) configured to receive from a network node (20) a page (18) that includes a paging identifier (18A) for the wireless device (16). The paging identifier (18A) may identify as a target of the page (18) a wireless device (16) associated with a particular subscriber. In fact, in some embodiments, the paging identifier (18A) is based on an encrypted subscription identifier for the wireless device (16) or is a pseudonym subscription identifier for the wireless device (16). In any event, the wireless device (16) is also configured to transmit to the network node (20) a response (22) to the page (18) that indicates the wireless device (16) was paged but that includes an identifier for the wireless device (16) that is different than the paging identifier (18A) included in the page (18).

摘要： A method of authorizing a subscriber user equipment to access a Network Application Function, NAF, in a Generic Bootstrapping Architecture, GBA. The method includes, at a Bootstrapping Server Function, BSF, receiving a request for key material for the subscriber user equipment from the NAF, wherein the NAF is associated with one or more NAF identifiers, NAF_IDs, obtaining subscriber information from a Home Subscriber System, HSS, the information including one or more NAF_IDs that are valid for the subscriber, authorizing the subscriber user equipment on the basis of the identity of said NAF and the NAF_ID(s) included within the subscriber information. In the event that the subscriber user equipment is authorized, key material is derived using a NAF_ID that is contained within said subscriber information; and the key material is sent to the NAF.
