Embodiments of a method performed by a Session Management Function (SMF) for providing Access Network (AN) are disclosed. In some embodiments the method comprises receiving from a Policy Control Function (PCF) a request for AN information. The method also includes determining whether the AN does not support reporting of the requested AN information. The method also includes upon determining that the AN does not support reporting of the requested AN information, sending, to the PCF, a notification that the AN does not support reporting of the requested AN information. The method also includes upon determining that the AN does support reporting of the requested AN information: acquiring the requested AN information and sending the requested AN information to the PCF.

Partial support of access network information

A method performed by a first node (e.g., a network exposure function (NEF)) is provided. The method includes: the first node subscribing to an event for one or more user equipments (UEs) at a second node (e.g., a policy and control function (PCF)). Subscribing to the event comprises indicating one or more filters selected from the group of (i) a set of network identifiers (e.g., data network names (DNNs)) that the subscription applies to, (ii) a set of network slice identifiers (e.g., single network slice selection assistance information (S-NSSAIs)) that the subscription applies to, and (iii) a set of locations to which the subscription applies.

Filters for bulk subscriptions

Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.

Network slice selection

A method performed by an application function, AF, for a communication network, wherein the AF has been informed, in a first notification, about an out-of-credit event associated with a user of a service provided by the AF, the method comprising sending subscription request, to a network function, NF, for requesting notifications about reallocation-of-credit events associated with one or more users of a service provided by the AF; receiving, from the NF, a second notification of a reallocation-of-credit event associated with the user of the service provided by the AF for which the AF has been informed about the out-of-credit event, such that the AF can perform one or more second actions with respect to the service.

Application awareness of credit conditions in communication network

Methods and apparatuses for data transmission. A method implemented at a first network function may comprise obtaining information related to network slice selection; and sending a reroute message to an access network node, wherein the reroute message including a container comprising at least one information element of the information related to network slicing selection.

Method and apparatus for granting or not granting a chargeable party at a session management with required quality of service utilizing a MAC address

A method by a network function communicating with a unified data repository of a communications network. The method including receiving from the UDR a subscription identifier for a subscription by the network function to receive data change notifications from the UDR. The method also including sending toward the UDR a change request containing an instruction to change data in the UDR and containing the subscription identifier to signal the UDR to not send to the network function a notification regarding this change to the data.

Change request with indication that no notification of subscribed data change is to be sent to requesting network function

A method in a network node is described. The method includes receiving a discovery request from a first network function (NF) node to discover at least one media NF type node. The discovery request indicates a media NF type of the at least one media NF type node. The media NF type is one of an access media gateway (A-MGW), an Internet Protocol (IP) multi-media gateway (IM-MGW), and a media resource function (MRF). The method further includes discovering the at least one media NF type node and transmitting a discovery response to the discovery request. The discovery response indicates the discovered at least one media NF type node and at least one corresponding NF profile. The at least one corresponding NF profile comprises at least one of one or more media types, one or more supported codecs, and transcoding support information.

Media gateway dynamic discovery in IMS

Systems and methods are disclosed herein for event notification in a core network of a cellular communications system. In one embodiment, a method performed by a first Policy and Control Function (PCF) serving an Access Management (AM) policy association for a User Equipment (UE) wherein the first PCF is comprised in a core network of a cellular communications system comprises subscribing to an event exposure service of a second PCF serving a Session Management (SM) policy association for the UE. The method further comprises, responsive to subscribing to the event exposure service of the second PCF, receiving a report from the second PCF. In this manner, separate deployments of the first and second PCFs are enabled and still the first PCF serving the AM policy association for the UE can implement AM policies for the UE, e.g., based on UE data usage, e.g., of specified service bundles.

Extension of Npcf_EventExposure with usage monitoring event

Embodiments include methods of updating a background data transfer (BDT) policy negotiated between an application function (AF) and a core network (CN) of a telecommunication network. Such methods can be performed by a Policy Control Function (PCF) of the CN and can include, in response to receiving a notification of degraded network performance of a network area, determining that the negotiated BDT policy is affected by the degraded network performance and an Application Service Provider (ASP) associated with the negotiated BDT policy requested a warning notification. Such methods can include determining, at least based on operator policies, updated BDT policy information for the negotiated BDT policy, wherein the updated BDT policy information comprises at least one of the following: at least one candidate BDT policy, and updated conditions for the negotiated BDT policy. Such methods can include sending the updated BDT policy information to the AF.

Updating a background data transfer policy negotiated between an application function and a core network

A method that includes a policy function transmitting to a depository function a request for information; and the policy function receiving a response to the request, wherein the response comprises: a usageMonDataLimit instance comprising a limit identifier; and a usageMonData instance corresponding to the usageMonDataLimit instance, wherein the usageMonData instance also comprises the limit identifier.

Embodiments of the present disclosure relates to a method and an entity for transmitting a plurality of media access control, MAC, addresses. A method performed at a first entity for transmitting a plurality of media access control, MAC, addresses, comprises: transmitting (S), to a second entity, a message including a first parameter and a second parameter. The first parameter and the second parameter indicate the plurality of MAC addresses. The plurality of MAC addresses may comprise a plurality of source MAC addresses; and/or a plurality of destination MAC addresses.
