摘要： A method performed by a wireless device is provided. The method comprises identifying that an Access and Mobility Management Function (AMF) relocation procedure with re-route via a Radio Access Network (RAN) node is being performed for the wireless device and generating a key associated with a primary authentication of the wireless device. The method further comprises using the key for performing a Non Access Stratum Security Mode Control (NAS SMC) procedure with a first network node operating as a target AMF, and wherein the use of the key by the wireless node is restricted such that the wireless device is restricted from using the key for at least one procedure other than the NAS SMS procedure with the first network node operating as the target AMF.

摘要： Methods for a user equipment (UE) configured to establish a secure application session with an application function (AF) associated with a communication network. Such methods include sending, to an access and mobility management function (AMF), a request for binding information related to a non-application-specific anchor security key (Kakma) for a user. The request includes a first identifier related to a network subscription of the user. Such methods include receiving, from the AMF in response to the request, a second identifier (B-TID*) of a binding between Kakma and an authentication server function (AUSF) that generated Kakma. Such methods include establishing a secure application session with the AF based on the received second identifier. Other embodiments include complementary methods performed by AMFs, authentication server functions (AUSFs), and unified data management (UDM) functions in the communication network. Other embodiments include network nodes configured to perform such methods.

Such methods can include receiving, from an application function, a request for a security key specific to an application session for a particular user. The request can include a representation of the following information associated with the particular user: a first identifier of a non-application-specific anchor security key, and a second identifier related to a network subscription. Such methods can also include, based on the representation, determining an authentication server function that generated the non-application-specific anchor security key. Other embodiments include complementary methods performed by application functions, authentication server functions, and unified data management functions in the communication network. Other embodiments include network nodes configured to perform such methods.

摘要： A user equipment ("UE") in a wireless communication network can receive a plurality of signals from a plurality of nodes. The UE can further determine a plurality of radio signal strength measurements. Each radio signal strength measurement can be associated with a signal of the plurality of signals received from the plurality of nodes. The UE can further determine whether there is an indication that a first node of the plurality of nodes may be an imposter node based on the plurality of radio signal strength measurements.

摘要： Related to reallocation of an Access and Mobility Management Function (AMF) for wireless communications between a User Equipment (UE) and a Radio Access Node (RAN). The method comprises establishing an initial security context between an initial AMF and the UE, selecting a target AMF (200) different from the initial AMF to provide one or more services requested by the UE, and transferring the initial security context from the initial AMF to the target AMF via the RAN to establish a new security context between the target AMF and the UE.

摘要： The AMF re-allocation procedure for an Initiating AMF (16) that has reroute capability via an Access Network (AN) is optimized in scenarios where a wireless device (12), such as a User Equipment (UE), for example, already shares a 5G security context with in a Last Serving AMF (18) that is different from the Initiating AMF, and where the Initiating AMF and the Last Serving AMF can communicate with each other via an interface.

摘要： A method performed by a first Information Centric Networking (ICN) network node for generating a number of data contents to a number of respective communication devices is provided. The first ICN network node operates in an ICN network 100. The first ICN network node aggregates (501 ) a number of requests received from a second ICN network node, based on that each request according to a common part of the request is associated with the same theme of the data content being requested by each of the respective communication device. Each aggregated request further comprises a respective customized part associated with the data content. The customized part is requesting the data content to be customized for being consumed in the respective communication device. The first ICN network node locates (502) a set of components corresponding to the requested data content according to the common part, and then generates (503) a number of transformed data contents based on the aggregated requests and the located set of components. Each respective transformed data content fulfils the requested common part and the requested customized part of each respective request and is customized for being consumed in the respective communication device.

摘要： Optimized complex event processing in a software-defined network is provided. A computing device receives a rule that identifies a source device and an event notification condition. A network inventory structure that identifies a plurality of nodes in the network and corresponding processing capabilities is accessed. A particular datapath node of the plurality of nodes is identified. A packet flow window criterion and a packet operation are determined based on the event notification condition. A particular virtual network function (VNF) of a plurality of VNFs is identified based on the rule. A controller node datapath configuration command that comprises a source device identifier that identifies the source device, the packet flow window criterion, the packet operation, and a VNF identifier that identifies the particular VNF is generated. The controller node datapath configuration command is sent to a controller node of the plurality of nodes.
