Abstract: A method for a target mobility management entity and a target mobility management entity for executing the method in a core network to communicate network function (NF) utilization information with a source mobility management entity during a change of mobility management entity are disclosed. The method comprises: receiving at least one old NF identifier (ID) from the source mobility management entity that corresponds to an old NF entity serving a user equipment (UE); determining to either use the at least one old NF ID or to use at least one new NF ID that corresponds to a new NF entity of a same NF type as the old NF entity; and communicating, to the source mobility management entity, information that indicates to the source mobility management entity whether the target mobility management entity uses the at least one old NF ID or uses the at least one new NF ID.

Abstract: A message authentication code, for a message transmitted and received over a communications network, is formed by applying inputs to an integrity algorithm acting on the message. The inputs comprise: an integrity key; a value indicating a transfer direction; and a frame-dependent integrity input, wherein the frame-dependent integrity input is a frame-dependent modulo count value that also depends on a random value and on a frame-specific sequence number.

Abstract: The invention relates to mobility management nodes and methods of the mobility management nodes of enabling delivery of a Mobile Terminating, (MT) Short Message (SM) to a mobile terminal.
In a first aspect of the invention, a method of a mobility management node is provided for enabling delivery of a Mobile Terminating, (MT) Short Message (SM) to a mobile terminal which currently is in extended idle mode discontinuous reception, eDRX, mode. The method comprises receiving an indication from a Short Message Service Gateway Mobile Switching Centre (SMS-GMSC) that the SM is to be delivered, receiving a notification that the mobile terminal has exited an extended idle Discontinuous Reception (eDRX) mode before a paging occasion has occurred, and submitting, in response to the notification, a message indicating to the SMS-GMSC that the mobile terminal is available for delivery of the SM.-

Abstract: According to one aspect of the present disclosure, a method of paging policy differentiation in a 5G telecommunications network is provided. A User Plane Function (UPF) receives downlink data for a target User Equipment (UE), and provides a data notification to a Session Management Function (SMF), the data notification comprising a Quality of Service (QoS) indicator, which the SMF uses to determine QoS Information (QoSI) that is sent to an Access Management Function (AMF). The AMF determines whether a paging policy selection should be performed by the AMF or by a Radio Access Node (RAN) that serves the target UE: if by the AMF, the AMF selects a paging policy based on the QoSI and sends a paging message to the RAN, which pages the UE; if by the RAN, the AMF provides paging policy information to the RAN, which selects a paging policy and pages the UE accordingly.

Abstract: Disclosed herein is a method of operation of a network node and a corresponding network node in a Neutral Host Network (NHN) in relation to an Online Set Up (OSU) procedure by which User Equipment devices (UEs) are enabled to access a data network via the NHN where the NHN comprises one or more Access Points (APs) that provide wireless access according to a cellular communications technology. The method of operation of the network node comprises: obtaining a filter list that defines limitations on a connectivity of a Packet Data Network (PDN) connection established for OSU between a UE and a Participating Service Provider (PSP); and utilizing the filter list such that traffic on the PDN connection is limited to traffic between the UE and one or more other network nodes of the PSP that perform operations related to OSU.

Abstract: A method for assigning a cellular network identity. The method comprises receiving (222), in a user equipment capable to attach to a cellular network and a wireless local area network, a unique representation of a user equipment context of the user equipment and in what cellular network node the user equipment is or is going to be attached, from a network node. The unique representation is labelled (224) as a cellular network identity and cellular network identity is stored (226) a pseudonym identity and/or a fast re-authentication identity in a memory in the user equipment.

Abstract: A method performed by an Access and mobility Management Function (AMF). The method includes receiving from a Session Management Function (SMF) a request to establish User Plane (UP) for a user equipment's (UE's) protocol data unit (PDU) session. The request includes information indicating an access type. The method also includes, in response to the request, performing the steps of: determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access and, as a result of determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access, the AMF initiates paging of the UE by the 3GPP access, the paging initiation comprising transmitting to a Radio Access Network, RAN, node a page request to page the UE.
