Abstract: Protocol Data Unit (PDU) sessions in a communication network (10) provide logical interconnections between Data Networks (DNs) (16) and respective User Equipments (UEs) (12) that access the DNs (16) via the communication network (10), and the communication network (10) establishes one or more affiliated sessions in conjunction with each PDU session, such as an affiliated charging or policy control session. Rather than requiring the high signaling overhead associated with mass terminations of these affiliated sessions on a per session basis, the Network Functions (NFs) (32, 34, 36) contemplated herein provide for batch termination of a potentially large plurality affiliated sessions, based on the exchange of a corresponding batch termination message. Disclosed batch termination techniques include the exchange of information during session establishment, for later determination of which affiliated sessions are subject to batch termination.

Abstract: A packet core system includes a User Plane, UP, a Control Plane, CP and an Online Charging System, OCS. The UP and CP are split, and the UP and CP allow communication over one or more SX interfaces. The UP is adapted for initially receiving a message such as a Sx/PFCP Session Establishment Request from the CR and responding with a message such as a Sx/PFCP Session Establishment Response to the CP, and receiving a message such as a Sx/PFCP Session Modification Request from the CP and responding with message such as a Sx/PFCP Modification Response to the CP. At least one of the Sx/PFCP Session Establishment Request and the SX/PFCP Session Modification Request includes a Generic Buffering Information Element indicating a generic buffering action.

Abstract: Methods of pre-emptive credit control, as well as corresponding network elements and a computer program are disclosed. According to one aspect, a method is performed in a network element comprising receiving, from an online charging system, at least one pre-emptive credit control directive for a subscriber, the credit control directive applying to at least one rating group; storing the at least one pre-emptive credit control directive in the network element and applying the at least one pre-emptive credit control directive at content or service delivery start, prior to any service or content received from, or addressing, the subscriber and belonging to the at least one rating group being forwarded from the network element.

Abstract: Example embodiments presented herein are directed towards a Packet Domain Network Gateway (PGW), and corresponding methods therein, for service usage reporting and quota management in a Policy and Charging Control (PCC) based network. Example embodiments presented herein are also directed towards an Online Charging System (OCS) for receiving service usage reporting and quota management in a PCC based network. Quota reporting and quota management is performed on a pre-rating group basis.

Abstract: The disclosure pertains to the field of Credit Control. More particularly the disclosure relates to methods of pre-emptive credit control, as well as to corresponding network elements and to a computer program. According to one aspect the disclosure relates to a method performed in a network element comprising receiving, from an online charging system, at least one pre-emptive credit control directive for a subscriber, the credit control directive applying to at least one rating group; storing the at least one pre-emptive credit control directive in the network element and applying the at least one pre-emptive credit control directive at content or service delivery start, prior to any service or content received from, or addressing, the subscriber and belonging to the at least one rating group being forwarded from the network element.

Abstract: Example embodiments presented herein are directed towards a Packet Domain Network Gateway (PGW) (400), and corresponding methods therein, for service usage reporting and quota management in a Policy and Charging Control (PCC) based network. Example embodiments presented herein are also directed towards an Online Charging System (OCS) (500) for receiving service usage reporting and quota management in a PCC based network. Quota reporting and quota management is performed on a per-rating group basis.

Abstract: The present invention relates to an arrangement, for allowing compensation of lost, discarded or unsent traffic on the downlink in a communication system supporting communication of packet data and classification of mobile traffic allowing application of different charging schemes for different types of traffic. It comprises a packet data node (PDN, G-PDN; GGSN; SGSN, CGSN) handling classification of traffic into different types, e.g. service class, and for applying an appropriate charging scheme depending on type. Said node provides (labels) and sends information relating to at least type, e.g. service class, to subsequent nodes (PDN, SGSN; RNC; BSC) on the downlink to a mobile station and a subsequent node (PDN; SGSN; RNC; BSC) detecting a packet loss, notes said loss and enables use of the information of the said loss together with at least type information to enable for correction of charging due to traffic loss.
