电信计费系统作为电信企业的核心支撑系统之一，肩负着用户费用计算以及欠费回收的重任。随着电信业务的不断发展，其处理的业务种类越来越多，数据量越来越大。从最初的月结计费发展到如今的实时计费，计费系统的处理时间要求越来越高。可以说，计费系统的处理效率是衡量系统好坏的一个重要标准。
整个计费系统包含了一系列的业务功能，从开始的计费处理到最后的收费处理，其中经历了若干个业务环节。其中，计费处理环节为计费系统的核心功能，其处理数据量和时间要求都是计费系统中最高的。将数据加载到主存中，然后建立索引进行访问，是计费处理中普遍采用的方法。
本文首先对当前几种主流的索引技术进行研究和分析。它们包括：顺序索引、散列索引、AVL树索引、B-树索引、B+树索引和位图索引。然后对计费处理中的资料特性和操作特性进行分析，在结合各类索引技术的特点的基础上，提出用B+树与位图索引相结合的新模式，用其来替代目前使用的顺序索引模式。
为论证新旧两种索引模式的优劣。笔者搭建了一个测试平台，对两种索引模式进行实现。选取计费处理中的典型数据和操作情况，进行测试。通过对测试结果数据的比较，得出本文的结论，即B+树与位图索引相结合的模式更适用与计费系统。最后笔者就研究工作进行总结，并指出后续工作的方向。

Telecom Billing System as the core telecommunications business support system, one of the shoulders users as well as the cost of recovery of arrears of responsibility. With the continuous development of telecommunications business, and its deal with the growing number of business types, increasing the amount of data. The initial monthly statements from billing to the development of today's real-time billing and accounting system to deal with the increasingly high demand for a time. It can be said that the accounting system to measure efficiency is an important quality system standards.
Accounting system as a whole contains a series of business functions, from the beginning of the end of the handle billing processing fee, which has gone through a number of business segments. The billing segments for the accounting system to deal with the core functions of its deal with the amount of data and time-accounting system are the highest. Data will be loaded into main memory, and then visit index is commonly adopted in dealing with billing.
In this paper, several of the current mainstream technology index research and analysis. These include: the order of the index, hash index, AVL tree index, B-tree index, B + tree indexing and bitmap index. And then to the billing information processing characteristics and operating characteristics, combined with the technology index all types of features on the basis of the proposed B + tree and bitmap index combined with the new model to replace its current order Index mode.
As a demonstration model of the old and the new index is good or bad. I set up a test platform for the realization of the two index model. Select billing processing of data and typical operation, for testing. The results of the test data comparison, this article come to the conclusion that B + tree and bitmap index combined with the model more applicable and billing systems. Finally, I would sum up the research and noted that follow-up direction.
