Intercommunication method for information transmission in data flow charge based on service

Abstract

The invention discloses a method of interfacing with information delivery based on the business data stream charge. The method comprises the steps as follow: A, the corresponding business and the charge principle thereof are decided by a charge principle functional entity CRF according to the charge input information of an application functional entity AF or an on-line charge system OCS, and the trigger point information of the corresponding business needed during the subsequent implementation process is decided; B, the trigger point information is carried inside an acknowledgment message by the CRF and is then sent to the AF or OCS; C, the trigger point information is stored and a trigger point is set by the AF or OCS according to the trigger point information; D, the received information is judged whether matched with the trigger point by the AF or OCS during the subsequent implementation, and step E is implemented in event of YES, or the received information is not processed and the process is end; E, the received information is structured into a charge input information and then is sent to the CRF through the AF or OCS, and the charge principle is changed by the CRF according to the input information.

Description

technical field [0001] The invention relates to the charging technology of the mobile packet service, in particular to an interactive method for information transmission in charging based on the data flow of the mobile packet service. Background technique [0002] With the gradual widespread application of mobile packet services, how to accurately and reasonably bill mobile packet data services has become a topic of general concern to mobile operators. [0003] The current general packet radio service (GPRS) network structure can only identify the level of access point name (APN) and active packet data protocol content (PDP context) for data flow. In reality, multiple parallel service data streams are likely to be carried by the same PDP Context, and different service data streams may use different charging methods. The current GPRS network cannot meet this requirement. In order to adopt different billing solutions for different types of service data streams, it is necessar...

Problems solved by technology

[0035] However, such an implementation is very inflexible. The method of notifying the CRF whenever a parameter changes will increase the load on the Rx / Ry interface, and many of the issued information are meaningless.

The method of pre-configuring trigger points can only cope with simple situations, and the configured trigger points are all static. If operators want to provide flexible and diverse billing strategies in combination with service usage, this method cannot be satisfied.

What's more, AF / OCS and CRF are not necessarily located in the same operator network, and different operator networks have different charging policies based on service data flow. For the same service, in an operator's charging policy, a The modification of parameters needs to change the current charging rules, but in another operator's charging policy, it may not need to make any changes to the charging rules being implemented

Therefore, this method in which AF / OCS always decides to send charging input information during the service execution process is not conducive to the development and implementation of charging based on service data flow
