摘要： TS 29.500, usually the feature negotiation is done when the subscription is created by the NF consumer. P: For default notification subscriptions, the NF consumer registers the default subscriptions in NRF and NF producer discover and directly send the notification towards the callback URI without subscription creation procedure. S: NF to register the supported features in default subscription. The NF producer can get aware the supported feature of the NF consumer and adjust the notification accordingly. TS 29.510, API Version Control and feature negotiation between NF producer and NF consumer. In 5GC, a NF Producer may subscribe to another NF producer on behalf of the NF consumer with directly reporting. P: No way for the NF consumer to indicate the supported API version and features of the second NF producer which will directly report to the NF consumer. S: New header to allow the NF consumer to indicate the supported API version and features.

摘要： A method for supporting envelope reporting in a radio communication network having a control plane, CP, function separated from a user plane, UP, function, is presented. The method is performed in a CP node of the radio communication network and comprises setting (S100) a time quota mechanism, TQM, in a usage reporting rule, URR, to which its corresponding service data flows, SDFs, are applicable for envelope for envelope reporting, setting (S100) at least one reporting trigger in the URR, to instruct the UP function to generate a usage report upon closure of an envelope, setting (S100) a measurement method in the URR, to instruct the UP function to collect usage of volume, time and/or event, sending (S110) the set URR to the UP function, receiving (S120) one or more usage reports from the UP function, in response to the sent URR, wherein the received usage report(s) comprises at least a usage report trigger set to envelope closure, determining (S130) a starting time and/or an ending time for each envelope, based on the received usage report(s), and storing (S140) each envelope, with the determined starting time and/or ending time, for online or offline charging. A CP node, a UP node, a computer program and a computer program product are also presented.

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.

摘要： A method (400) performed by an NF service consumer. The method includes invoking (s402) a discovery service for discovering NF service producers. Invoking the discovery service comprises: generating (s404) a discovery message (253) comprising a query; and transmitting (s406) to an NRF (204), the discovery message comprising the query. The query included in the discovery message (253) comprises a first query parameter comprising a first NF type value identifying an NF type of a target NF being discovered. The query further comprises at least one of: i) a second query parameter comprising a supported features value specifying that the NF service consumer invoking the discovery service supports selection of combined NFs, or ii) a third query parameter comprising a second NF type value identifying a set of one or more NF types. The third query parameter indicates either a) that the NF service consumer prefers the NRF to return a set of NF instance profiles wherein each NF instance profile included in the set is for an NF instance that supports all of the NF types identified by the first and second NF type values.

摘要： A method and apparatus for session management. The method at a control plane function comprises determining data to be restored in a user plane function or a first Internet Protocol (IP) address pool identifier. The method further comprises sending a first session establishment request to the user plane function, wherein the first session establishment request includes a data restoration flag and the data to be restored in the user plane function or includes the first Internet Protocol address pool identifier. The first Internet Protocol address pool identifier is used by the user plane function to assign an IP address to a user equipment from the first Internet Protocol address pool identifier.

摘要： A method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

摘要： Example embodiments presented herein are directed towards determining a Proxy Mobile Internet Protocol version 6 (PMIPv6) control plane used by a network node peer in an Internet Protocol version 4 (IPv4) transport network. The example embodiments provide a mechanism in PMIP protocol stack, to allow a Mobility Access Gateway/Local Mobility Anchor (MAG/LMA) node such as SGW (which may be supporting both PMIP draft and PMIP RFC) to decide which PMIP protocol stack shall be used to communicate to the peer node, i.e. LMA/MAG.
