Account resource reservation and distribution method used for IMS multi-service on-line charging

Abstract

An account resource reservation and distribution method in IMS multi-service On-line Billing; the operation step comprises: enlarging message format of CCR in DCCA protocol alternated between charged entity device of IMS and OCS, increasing attribute value BI of business bandwidth information, reporting CCR message updating the request type to the OCS by the charged entity device; OCS initializing, stopping or updating according to the different types of the received CCR message; dynamically correcting the business standard resource according to QoS level running in business example, executing the business standard resource updating arithmetic; executing resource reservation arithmetic and resource recovery arithmetic based on the standard resource; or executing resource redistribution arithmetic, redistributing the recovered resource to the new business example and the business example of the recovered resource; OCS returning CCA message to the charged entity device. The method can ensure high account resource utilization rate and not cause large network and system resource expenditure.

Description

technical field [0001] The invention relates to an account resource reservation and distribution method used in IMS multi-service online charging, and belongs to the technical field of IMS multi-service online charging in communication technology. Background technique [0002] In the 2G mobile communication system, the online billing of the voice service is realized through the introduction of the intelligent network. At the same time, each prepaid user's account is only allowed to access one prepaid call service, which is essentially equivalent to all the balances on the account. It is used by this service during the call, and the billing process of this single-service exclusive account is relatively simple. In the 3G mobile communication system, by introducing IP Multimedia Subsystem IMS (IP Multimedia Subsystem) to achieve the integration of voice, data, video and other differentiated services, the online charging mechanism of IMS allows each prepaid user to Conduct mult...

Problems solved by technology

Since the account balance is limited, if the amount of resources reserved by OCS is too large each time, the business that receives the resource allocation may end up with a lot of unused resources, so that these remaining resources will be released after the business ends; However, before release, the account balance may no longer have enough resources to support users to access new services, resulting in rejection or waiting of service access, resulting in low utilization of account resources

If too few resources are reserved each time, the allocated resources will be exhausted quickly. In this way, the IMS billed entity frequently initiates unit reserved RU operations and debit DU operations to the OCS, thereby increasing network traffic. Signaling load and system processing overhead
