Off-line charging system and method

Abstract

The system comprises: a billing trigger entity for triggering and collecting billing information; the call ticket generating entity for colleting billing information and generating call ticket. Wherein, the communication between said billing trigger entity and the call ticket generating entity is implemented using messages. By the invention, the needs for providing a unified billing method for each kind of packet service can be satisfied.

Description

technical field [0001] The invention relates to an off-line charging system and method for services. Background technique [0002] At present, there are two billing methods in the telecommunications field, one is offline billing based on CDR (charging data record), the billing process does not affect the provision of services, and the other is online billing in which the billing process affects the service provision process . [0003] Offline charging is a charging method in which the use of network resources occurs simultaneously with the collection of charging information, and it has a wide range of application scenarios. A billing method in which billing information is transmitted through the serial billing logic function, generates a CDR, and transmits the CDR to the billing and accounting system. Offline charging is a charging form in which charging information does not affect service provision in real time. [0004] The concept of offline billing is generally simila...

Problems solved by technology

[0016] (1) Each business application server needs to implement complex bill processing functions, which undoubtedly increases the complexity of the business application server in bill processing;

[0017] (2) Since the generation of billing information and the generation of billing bills are implemented in one entity, therefore, distributed algorithms cannot be used

Therefore, it is not convenient to expand and maintain the system;

[0018] (3) The inconsistency of billing methods has caused great obstacles to the interconnection of telecommunication networks

[0022] Because the interface between the CDR acquisition entity and various OMA application servers is not very versatile, that is, the CDR acquisition entity and business applications are tightly coupled, such as the billing interface and bill acquisition entity applied to MMS cannot meet the requirements Other business applications, such as POC offline billing requirements

Therefore, the cost of Option 2 is still very high for network expansion and maintenance
