摘要： Systems and methods are disclosed herein that provide a mechanism for a first Network Function (NF) to directly or indirectly indicate, to a second NF, a set of NFs of the same type as the first NF that support at least some of the same types of services as the first NF. In some embodiments, a method of operation of a first NF in a core network of a wireless communication system comprise providing, from the first NF to a second NF, information that directly or indirectly indicates a set of NFs of a same NF type as the first NF that support at least some of one or more types of services provided by the first NF. The set of NFs can be used by the second NF when the second NF desires to invoke a service of the first NF, e.g., when the first NF is unavailable.

摘要： A system, method, node, user equipment and computer program for establishment of a secure connection between a user equipment (100) and a media gateway (130) at setup of a communication session with another party (150) is described. The media gateway (130) is controlled by a control server (120). The control server (120) receives a communication session setup request from the user equipment (100) and determines an indication of a security certificate of the media gateway (130). The control server (120) then sends the indication of the security certificate of the media gateway (130) to the user equipment (100), wherein the indication is sent before or in parallel to sending the communication session setup request towards said other party (150). The user equipment (100) then initiates a negotiation of security related parameters, based on the received indication of the security certificate of the media gateway (130). Then the secure connection between the user equipment (100) and the media gateway (130) is established, utilizing the negotiated security related parameters.

摘要： The present disclosure provides methods for event subscription management in a network comprising a set of NF nodes, and corresponding NF nodes. The method implemented at a first NF node includes receiving a subscription request of an event for a user equipment, UE, from a third NF node; transmitting, to a second NF node that serves the UE, a subscription report request for the event for the UE; receiving, from a fourth NF node that currently serves the UE, a UE registration request for the UE, including an indication indicating whether the UE is in a restricted service area; and determining whether to transmit a notification for the event to the third NF node based on the UE registration request. The present disclosure further discloses a corresponding method implemented at the second NF node. The present disclosure further provides corresponding computer readable medium.

摘要： Methods and apparatuses for establishment of protocol data unit (PDU) session are disclosed. According to an embodiment, a first network function determines whether a first session management function (SMF) for a PDU session to be established for a terminal device supports insertion/change of a second SMF. When determining that the first SMF for the PDU session does not support insertion/change of the second SMF, the first network function sends, to a second network function, a query request for discovering at least one second SMF that can serve whole public land mobile network (PLMN) to which the first network function belongs. The first network function receives a query response from the second network function.
