Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of NRF services access authorization. The method comprises generating, at a first device, an indication of whether an authorization is required for accessing a service provided by the first device; and transmitting the indication to a second device. With the solution of the present disclosure, the indication of whether an authorization is required for accessing a service provided by the NRF can be provided from the NRF to other NFs, which may improve the system performance without increasing the extra signaling overhead.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for indirect communication. In example embodiments, a method is provided. The method comprises receiving, at a second service communication proxy (SCP), a service request and an access token from a first SCP, the service request originating from a first network function (NF) for requesting a service from a second NF and comprising a header indicating scope information about the requested service; verifying the access token based on the header of the service request; and in response to the verification of the access token succeeding, transmitting the service request to the second NF without transmitting the access token to the second NF. As such, the verification of the access token is offloaded from the second NF to the SCPp, thereby reducing the overhead on the second NF.

Abstract: There are provided measures for task responsibility coordination. Such measures exemplarily comprise recognizing addition of said network function entity to a network entity composition, acquiring task coordination responsibility information with respect to said network entity composition, analyzing said task coordination responsibility information, and initiating, if said task coordination responsibility information does not define a valid task coordination responsible for a specific task, addition of said network function entity as said task coordination responsible for said specific task.

Abstract: Embodiments of the present disclosure relate to method, device and computer readable media for communications. A first device receives, from a second device, a request for establishment of a connection between the first device and the second device. If a first set of security parameters associated with the connection is identical to a second set of security parameters associated with a previous connection which was completed between the first device and the second device, the first device performs the establishment of the connection.

Abstract: Systems, methods, apparatuses, and computer program products for determination of non-3GPP interworking function(s) (N3IWFs), which support slices targeted by a device or user equipment (UE), are provided. One method may include transmitting, by a UE or device, a request to at least one network node. The request may be to obtain information on network slices supported by at least one N3IWF. The method may also include receiving, from the at least one network node, a response comprising information for one or more N3IWFs and, based on the received information for the N3IWF(s), selecting one of the N3IWF(s) to use to connect to a 5G core network (5GC).
