摘要： Methods and apparatuses for control of multicast broadcast service (MBS) are disclosed. According to an embodiment, a session management function (SMF) sends, to a user plane function (UPF), a first request for modifying a packet forwarding control protocol (PFCP) session for a protocol data unit (PDU) session associated with an MBS session. The first request comprises an identification of the MBS session. The SMF receives, from the UPF, a first response to the first request.

摘要： Methods and systems for transferring monitoring event information during a mobility procedure are provided. According to one aspect, a method for transferring monitoring event information during a mobility procedure comprises, at a first network node: receiving and storing subscription information indicating that a second network node has subscribed to get notification when there is a data delivery failure involving a User Equipment (UE), followed by the UE becoming reachable; detecting a data delivery failure involving the UE, and setting a flag to indicate that a data delivery failure involving the UE has occurred; receiving, from a third network node, a mobility related request; sending, to the third network node, a response to the mobility related request, comprising an indication that the third network node should notify the second network node when the UE becomes reachable and/or when then UE enters the IDLE state.

摘要： Embodiments of the present disclosure provide methods and apparatuses for assigning network address prefix. A method performed by a control plane function may comprise: receiving, from a terminal device, a request for assigning a network address prefix; determining whether the network address prefix is assigned by the control plane function or a user plane function; transmitting, to the user plane function, a PFCP Session Modification Request for requesting the user plane function to assign the network address prefix, if it is determined that the network address prefix is assigned by the user plane function; receiving, from the user plane function, a PFCP Session Modification Response including an assigned network address prefix; and transmitting the assigned network address prefix to the terminal device. The specific procedure for the terminal device to obtain the network address prefix from a network entity not directly requested by the terminal device may be defined.

摘要： A method of operation of a cellular communications system is disclosed. The method comprises: at a MME: receiving an attach request from a UE; sending a location update request to a HSS; receiving a location update acknowledgement; sending, to a DNS, a DNS query request comprising an APN FQDN; receiving a DNS query response comprising information that indicates candidate PGWs that satisfy the DNS query request and at least two PGWs belonging to a same PGW set; selecting the first PGW; sending, to a SGW, a first create session request that comprises information that indicates the first PGW; receiving a first create session response; sending an attach accept to the UE; and at the SGW: receiving the first create session request from the MME; forwarding the first create session request to the first PGW; receiving the first create session response; and forwarding the first create session response to the MME.

摘要： The present disclosure proposes network elements (NEs), methods at NEs for facilitating data forwarding, and a telecommunications system comprising the NEs. The method at a first network element for facilitating data forwarding may comprise: receiving, from a second network element, a first message comprising a first indicator indicating that a data forwarding function is supported by the second network element. Further, the first message may be a first request message which requests registering, at the first network element, one or more functions of the second network element comprising the data forwarding function. Further, the method may further comprise transmitting, to the second network element, a first response message comprising a second indicator indicating success of the registration.

摘要： The embodiments herein relate to a method performed by a gateway. The gateway detects that a procedure for activating or deactivating a bearer has been initiated. The gateway receives a first modify bearer or modify access bearers request message for the same PDN connection and UE as the bearer activation or deactivation procedure is intended for. The gateway detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway and associated with said same PDN connection and UE. The gateway accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.
