Problems solved by technology

This strategy leads to high service availability, but can lead to severe revenue loss for the operator in case the subscriber's credit balance is not high enough for transactions to be granted
[0018] According to the existing and currently proposed IMS architecture, there is no easy way to configure CTF nodes and / or OCS nodes in order to solve this unsatisfactory behavior in the IMS online charging model

Embodiment Construction

[0041] As mentioned above, there is a need for a more efficient use of the available infrastructure related to online charging in an IMS architecture. Currently, if the connection between the CTF implementing the Ro interface and the OCS node is not available, there is no way for the subscriber to establish a SIP session, even though the subscriber may have a credit balance that allows the session to be established. According to the invention, this problem is solved, for example, by augmenting credit control failure manipulation attribute value pairs (AVPs) with new values. The new value indicates that the CTF should proceed with the establishment of the requested session and buffer any credit control requests (CCRs) related to the requested session for later handling by the OCS. In the following description, the new value will be expressed as a CONTINUE_BUFFER indication.

[0042] In order to implement the invention according to the invention, the CTF is provided with the ab...

Abstract

A method of communication between two nodes providing online charging functionality in an IP Multimedia Subsystem IMS network, wherein the first node is configured to operate as a Charging Trigger Function (CTF), and wherein the second node is configured to operate as an online The charging service OCS operates. This approach allows mitigating the disadvantages stemming from low availability of OCS.

Description

technical field [0001] The present invention relates to a communication method between two nodes providing online charging functionality in an IP Multimedia Subsystem (IMS) network. In particular, it relates to a communication method between a first node configured to operate as a Charging Trigger Function (CTF) and a second node configured to operate as an Online Charging Service (OCS). Background technique [0002] IP Multimedia (IPMM) services provide a combination of voice, video, messaging, data, etc. within the same session. As the number of basic applications and possibly combined media increases, the number of services offered to end users will grow and the possibilities for enriching the communication experience between individuals will increase. This leads to a new generation of personalized rich multimedia communication services, including so-called "combined IP multimedia" services. [0003] IMS is a technology defined by the 3rd Generation Partnership Project ...
