    Abstract: This disclosure is directed to a method and a mobility management unit for performing the method of paging a group of wireless terminals served by one or more radio access network nodes. The method comprises. receiving for each wireless terminal in the group of wireless terminals a connection request message; allocating for each wireless terminal in the group of wireless terminals a terminal-identity with a group-identity where the terminal-identity or at least the group-identity is the same or at least partly the same for each wireless terminal; sending to each wireless terminal in the group of wireless terminals, in response to the connection request message, a connection accept message comprising the terminal-identity to enable paging the group of wireless terminals by a single paging message to each radio access network node serving one or more wireless terminals in the group of wireless terminals.

    Abstract: Embodiments of a method performed in a User Plane Entity (UPE) in a core network to perform a user plane initiated Packet Forwarding Control Protocol (PFCP) association release procedure are provided. In some embodiments, the method comprises, for each affected PFCP session, sending, to a Control Plane Entity (CPE), a PFCP session report request comprising an indicator that the PFCP session is being removed and one or more usage reports for the PFCP session, and deleting the PFCP session. The method further comprises sending, to the CPE, a PFCP association update request comprising information that indicates that the PFCP association update request is to initiate release of the PFCP association and an indicator that all non-zero usage reports for the affected PFCP session(s) have been reported. The method further comprises receiving, from the CPE, a PFCP association release request and sending, to the CPE, a PFCP association release response.

    Abstract: A network entity generates a discovery request and transmit the discovery request to a network repository entity, NRE, wherein, advantageously, the discovery request includes a set of query parameters, the set of query parameters comprising a set of candidate network entity identifiers (IDs) comprising at least a first candidate network entity ID (e.g., an1-SMF instance ID), wherein each candidate network entity ID included in the set of candidate network entity IDs identifies a candidate network entity.

    Abstract: Disclosed herein is a method for indirect communication in a core network of a wireless communication system using a Service Communication Proxy, SCP, with Transport Layer Security, TLS, the method comprising: at a Network Function, NF, service consumer: sending, to the SCP, a Hypertext Transfer Protocol, HTTP, message that is intended for a first NF service producer instance, the HTTP message using a Fully Qualified Domain Name, FQDN, of the SCP and having a path that includes a query parameter set to a first value; and at the SCP: receiving the HTTP message from the NF service consumer; obtaining a HTTP response for the HTTP message; and sending the HTTP response to the NR service consumer; and at the NF service consumer: receiving the HTTP response from the SCP.

    Abstract: The present disclosure provides a method in a network node implementing a Service Communication Proxy, SCP, function. The method includes: receiving, from a first Network Function, NF, a request destined to a second NF, wherein the request comprises information on the second NF; redirecting the request to a third NF, wherein the redirected request comprises information on the third NF; and transmitting a response to the first NF, wherein the response comprises the information on the third NF.

    Abstract: Disclosed herein is a method performed by a first network node (e.g., SMF/PGW-C #1) for interworking between a 4G Evolved Packet Network (EPC) and a 5G core (5GC). The method comprises: receiving, at a first network node, a request to create a session for a User Equipment (UE) for a particular Access Point Name/Data Network Name (APN/DNN); determining that the first network node is not configured to support a subscribed network slice of the UE that contains the particular APN/DNN; identifying a second network node (e.g., PGW2 or second SMF/PGW-C) that is configured to support the subscribed network slice of the UE that contains the particular APN/DNN; and transferring, to the second network node, the request to create a session for the UE for the particular APN/DNN.
