摘要:
A method for a Mobile Control Node, MCN, supporting handover of a packet switched, PS, voice call of a given user entity anchored in a IP Multimedia Subsystem (IMS) to a circuit switched, CS, voice call, by using a Single Radio Voice Call Continuity, SRVCC, function, whereby, —after handover from PS to CS (102) voice call pertaining to a user entity, UE, which UE is in a suspended mode (305, 206/209/303), and upon receiving a SRVCC CS to PS resume request message (107) from a mobile switching centre, MSC, —issuing an explicit/implicit resume message (109, 306) to a packet gateway (PGW) node or a serving gateway (SGW) node, causing the UE to resume PS services (110). Further a method for a Mobile Switching Centre (MSC) supporting handover of a packet switched, PS, voice call of a given user entity (UE) via an SP Multimedia Subsystem (IMS) to a circuit switched, CS, voice call, by using a Single Radio Voice Call Continuity, SRVCC, function, wherein—after handover from PS to CS (103), and after detecting hang up or dropped call (106) issuing (209) a SRVCC CS to PS resume request message (107) to a MCN, thereby effecting the user entity to resume PS services of the voice call for a given user entity (UE).

A Policy and Charging Rules Function, a PCRF (120), for use with a Policy and Charging Enforcement Function, a PCEF (135), over a Gx interface, and arranged to communicate with an Application Function, an AF (110), over an Rx interface. The PCRF (120) is arranged to receive a request from the AF (110) regarding Access Network Charging Correlation Information for the AF, and if such a request is received from the AF, the PCRF (120) checks if the Access Network Charging Correlation Information is known to the PCRF, in which case the PCRF (120) provides the information to the AF (110), and if the Access Network Charging Correlation Information is not known to the PCRF (120), it subscribes to the Access Network Charging Correlation Information from the PCEF (135) and to supply the Access Network Charging Correlation Information to the AF (110) after reception from the PCEF (135).
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 (Sioo) a time quota mechanism, TQM, in a usage reporting rule, URR, to which its corresponding service data flows, SDFs, are applicable for envelope reporting, setting (Sioo) at least one reporting trigger in the URR, to instruct the UP function to generate a usage report upon closure of an envelope, setting (Sioo) a measurement method in the URR, to instruct the UP function to collect usage of volume, time and/or event, sending (Sno) 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.

Embodiments of the present disclosure provide methods, apparatus and computer program products for network function service discovery. A method implemented at a first network node in a wireless core network with service based architecture comprises: determining, in response to trigger of network function selection for a terminal device of the wireless core network, at least one subscriber group that the terminal device is matched with; and retrieving at least one network function instance for the at least one subscriber group.
