Abstract: Comparing with the 2.5 generation communication system, the 3rd network system provides the consumers with more multi-background service. The characteristic of the 3rd generation network system can efficiently charge for many complicated digital services based on its platform. Meanwhile, the usage of component in J2EE construction makes the business logic independent from the Customer part and the Service-provider part, which greatly improves the needs of increasingly sophisticated business logic as well as provides more convenience to develop, maintain. This article first introduces the 3rd network system then analyzes the needs of 3G charging as well as gives the principle of the charging part. At last, it expatiates on how use J2EE to accomplish 3G charging.

Key words: 3G, charging, J2EE
