The embodiments herein relate to optimized procedure for Packet Flow Description (PFD) management. In one embodiment, there proposes a method () for managing Packet Flow Description (PFD), comprising: receiving (S) from a Session Management Function (SFM) () or a User Plane Function (UPF) () a demand message indicating the demand for at least one PFD rule for an application; detecting (S) the at least one PFD rule for the application; and notifying (S) information regarding the at least one PFD rule to the SMF () or the UPF (). The embodiments herein may achieve an optimized procedure for PFD Management which optimizes the delivery of PFD rules, by reducing the amount of signaling and by reducing the number of hops between the producer (AF) and the consumer (UPF).

Optimized procedure for PFD management

Methods and apparatuses for configuration of monitoring for terminal device are disclosed. According to an embodiment, a subscriber management node determines multiple first parameters which are provided from one or more servers and indicate requirements for monitoring a same terminal device. The subscriber management node determines, based on the multiple first parameters, a second parameter which is to be applied to the same terminal device to satisfy the requirements indicated by the multiple first parameters.

Methods and apparatuses for configuration of monitoring for terminal device

A method at a server may comprise obtaining one or more expected UE behaviour parameters having timing information of one or more or a group of UEs; and sending to a network exposure entity a first parameter provisioning message including the one or more expected UE behaviour parameters having timing information of one or more or a group of UEs.

Method and apparatus for user equipment behaviour parameters provisioning

A method implemented at a network exposure node is provided. The method includes: receiving, from a first node, a first message for deleting an event subscription for at least one user equipment, UE; determining whether the at least one UE is an individual UE or a group member UE; sending a second message to a second node, when the at least one UE is a group member UE, wherein the second message includes UE identification information of the at least one UE.

Method and apparatus for event monitoring

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

The present disclosure provides a method in a Network Exposure Function, NEF. The method includes: receiving, from an Application Function, AF, a request for dynamically reserving a Reliable Data Service, RDS, port resource in association with a Non-Internet Protocol 'IP' Data Delivery, NIDD, configuration, the request containing an indication indicating whether the reserving of the RDS port resource requires confirmation with the terminal device; and transmitting, to the AF, a response to the request.

Method and network node for port management

The present disclosure proposes network elements, methods at the network elements for facilitating reuse of IP address, a telecommunications system comprising the network elements. The method at a first network element for facilitating reuse of an IP address at multiple UEs comprising a first UE comprises: transmitting, to a second network element, a first request message associated with the first UE, the first request message comprising the IP address and a first indicator which, in conjunction with the IP address, uniquely identifies the first UE.

Reuse of IP addresses

The present disclosure provides a method and an apparatus for notifying an application function node about a reliable data service (RDS) configuration of a network. The method implemented at an exposure function node includes: obtaining an RDS configuration of a terminal device; determining an RDS capability of a network; and sending a message including information about the RDS capability of the network to the application function node, if the RDS capability of the network is changed. The RDS capability of the network indicates whether the network supports the RDS. The method implemented at an application function node includes: receiving, from an exposure function node, a message including information about the RDS of the network, if the RDS capability of the network is changed. Data transmissions of the application function node with improper configuration may be avoided.

Method and apparatus for notifying application function node about RDS configuration of network

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

The disclosure provides methods, apparatus and computer-readable media for subscribing to, and receiving event notification messages from a CAPIF core function. In one method performed by a subscribing network entity, the subscribing network entity sends an event subscription request message to the CAPIF core function. The event subscription request message comprises an indication of an event filter to be utilized by the CAPIF core function for filtering event notifications to be sent to the subscribing network entity. The event filter comprises an identity of one or more network entities associated with events to be notified to the subscribing network entity.

Method, apparatuses and computer-readable media relating to event subscription in a communication network

A method of operating a vehicle to anything, V2X, application enabler, VAE, server is provided according to some embodiments disclosed herein. The method includes receiving a registration request message from a V2X application specific server. The method further includes transmitting a registration response message to the V2X application specific server responsive to receiving the registration request message.
