Nokia Guangdong Telecom Firewall Construction successful case

Profile

Guangdong Telecom Billing and Settlement Center operates China's first provincial telecommunication network centralized billing and settlement system. The Centre is responsible for the billing and settlement of all voice telecommunications services in Guangdong Telecom.

The data flow between the backbone network of the billing and Settlement Center and the various offices and various data acquisition points should be kept in the best condition so that the billing and settlement system can work effectively. Reliable network security is important for the day-to-day operation of this "open" network, so that the entire system is protected against viruses, malicious attacks and the accuracy of data maintenance.

The billing and settlement system requires a firewall to provide strong network protection and maintain a high standard of broadband throughput. The billing center chooses Nokia's IP series Network security solution. Without reducing bandwidth and throughput, enterprise-class IP530 solutions meet all the needs of network security, and are highly scalable to meet the need for a further increase in the billing system's data flow. In addition, the Nokia patented IP cluster technology can create a firewall cluster to ensure a higher redundancy capability and achieve dynamic load balancing.

Guangdong Telecom Billing and Settlement Center

The Guangdong Telecom Billing and Settlement Center (Billing and Settlement Center) is responsible for the billing and settlement of all telecom voice services in Guangdong Telecom. Guangdong Telecom is the main telecom operator in Guangdong province. Billing Center is the Guangdong Telecom Company Science and Technology Research Institute of subordinate units. The Institute is one of three research and development centers in China Telecom.

Billing and settlement centers deal with more than 15 billion billing statements per year, and pay attention to the various billing and settlement systems and the operation of China's telecommunications industry. The clearing system of Guangdong Telecom Network, which is operated by the Billing and Settlement Center, is the first provincial centralized network clearing system in China Telecom. The center also developed long-distance centralized billing system, fixed network IP integrated Billing service system, 200 card billing system, fixed network prepayment billing system and other application systems. The billing and Settlement Center is committed to providing new telecom services to Guangdong Telecom.

Network needs speed

One of the core tasks of the billing and settlement Center is the processing of the billing price. The Billing center first collects the original billing of the local switch in real time, then carries out a series of processing, and finally sends the billing and specific accounts back to the local billing center. The process deals with sensitive data and needs to be secure and timely, which affects the fees charged to telecommunications users.

If the telecom business in Guangdong Province increases, the amount of data needed to be processed by the billing and settlement system will increase. Similarly, the access throughput of the billing and settlement system is critical to the accuracy and efficiency of the Billing center and the branch offices of Guangdong Telecom.

Open networks also need strong security, especially for viruses and malicious hacker attacks. The hacker attack has the extremely destructive, not only threatens the billing settlement Center's portal website, but also through the office intranet to the entire billing settlement system poses the threat. Billing and settlement system based on centralized architecture, vulnerable to attack.

Find the right solution

Mr. Tenya, deputy Director of the accounting department of the Institute of Science and Technology, Guangdong Telecom Company, recalls the process of choosing a new firewall, saying, "Firewalls, of course, provide powerful security, but other factors are important, such as scalability to meet the increasing demand for network traffic, high reliable fast throughput without bottlenecks, At the same time, the whole system without interruption, enhance processing access to complete the billing process, without loss of connectivity.
