Problems solved by technology

[0016] Assuming the same or similar quota decisions are used for billing users, regardless of whether offline or online billing is used, the billing model should be structured so that consolidation is avoided as much as possible; however, this is not always possible, or it will hinder service and Rate distinction

Embodiment Construction

[0042] An embodiment of the present invention aims to provide a conventional mechanism for sending and processing charging-related data between IMS nodes, so that a single CTF can generate charging not only for its own service, but also for data from other nodes. fee data. This would make it possible for the charging control system to remove or at least reduce the need to consolidate charging data.

[0043] According to an embodiment of the invention, certain nodes within the IMS system will be able to use SIP signaling to carry data related to charging decisions made by the charging control system, each such node sending its own charging data Added to SIP signaling. One possible container for this data is a private header, e.g. defined in RFC 3455 "Private Header (P-Header) Extensions to the Session Initiation Protocol (SIP) for the 3rd-Generation Partnership Project (3GPP)" and with There is 3GPP TS 24.229 "IP multimedia call control protocol based on Session Initiation Pr...

Abstract

A method is provided for use in an IP Multimedia Subsystem, IMS, in which a session control protocol (such as the Session Initiation Protocol, SIP) is used to establish and manage sessions within the IMS. The method comprises using session control protocol messages (such as Session Initiation Protocol messages) to carry node- specific charging information, where the charging information is required for charging purposes at a charging control system of the IMS. A private header part (such as a P- Charging-Vector header) of the session control messages may be used to carry the node-specific charging information. The node-specific charging information may comprise charging data and at least one of : an indication of the type of the charging data; a name or identifier of the node, allowing the node to update charging data which relates to the node and which is carried by a session control message received by the node; and an indication of the version of the charging data, a different version indication being used to indicate different charging data; node name; version number; data name; and value. At least one session control protocol message may be used to carry node-specific charging information relating to a plurality of different nodes.

Description

technical field [0001] The present invention relates to methods and devices for use in an IP Multimedia Subsystem. Background technique [0002] IP multimedia services provide a dynamic combination of voice, video, messaging, data, etc. within the same session. By increasing the number of basic applications and media that can be combined, the number of services provided to end users will increase and the experience of human-to-human communication will be enriched. This will lead to a new generation of personalized, rich multimedia communication services, including so-called "combined IP multimedia" services. [0003] UMTS (Universal Mobile Telecommunications System) is a third generation wireless system designed to provide higher data rates and enhanced services to subscribers. UMTS is the successor of the Global System for Mobile Communications (GSM), and an important innovation step between GSM and UMTS is the General Packet Radio Service (GPRS). GPRS introduces packet ...
