Abstract: Techniques for securing an identifier of user equipment for a request external to a communication network are disclosed. For example, a method comprises receiving, at a network entity, a request for identification information for user equipment from an entity external to a communication network to which the network entity belongs. The network entity generates a secure identifier for the user equipment, wherein the secure identifier comprises an encrypted form of a public subscription identifier associated with the user equipment. The network entity sends the secure identifier to the external entity. The network entity receives the secure identifier in a subsequent request from the external entity. The network entity utilizes the received secure identifier to confirm the received secure identifier corresponds to the user equipment.

Abstract: There are provided measures for local user plane function control. Such measures exemplarily comprise obtaining access network related information, receiving, from a session management function entity, at least one pre-rule, generating, based on said at least one pre-rule and said access network related information, a first rule of at least one rule related to local traffic offloading, assigning said first rule to a first user plane function entity of at least one user plane function entity under control of said intermediate session management function entity, and transmitting said first rule to said first user plane function entity.

Abstract: Systems, methods, and software of directly connecting a SIM-less device with a cellular network. In one embodiment, User Equipment (UE) includes a Subscriber Identity Module (SIM) provisioned with a plurality of subscription profiles for subscriptions to the cellular network. The UE establishes a direct communication with a SIM-less device that does not have a subscription with the cellular network. The UE selects one of the subscriptions provisioned in the SIM as a temporary subscription assigned to the SIM-less device to allow the SIM-less device to establish a direct connection with the cellular network using the temporary subscription, and transmits a message to the SIM-less device via the direct communication containing subscription credentials for the temporary subscription. The SIM-less device may therefore register with the cellular network using the subscription credentials provided by the UE, and establish a direct connection with the cellular network using the temporary subscription.

Abstract: A method, apparatus and computer program product receive a traffic redundancy indication from a user equipment in a communication network or from a policy controller. The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.

Abstract: User equipment appends a header to a non-access stratum (NAS) message to form an encapsulated NAS message. The header is formed according to a wireline access network protocol. The user equipment transmits the encapsulated NAS message over a wireline connection between the user equipment and an interworking function of a core network. The interworking function receives the encapsulated NAS message over the wired connection and forwards the NAS message to a core network entity selected based on addressing information included in the header. A point-to-point control plane session can be established between the user equipment and the interworking function in response to a session request transmitted by the user equipment. The point-to-point control plane session can be used to convey encapsulated NAS messages, which can be used to request establishment of an NAS session for a user plane connection to the core network.
