Telecom Australia (Telstra) in 3G operations, occupy nearly half of the national market share of 3G, mobile broadband 200 percent annual revenue growth, the global opening of the first HSPA +, the industry covered by a single station furthest distance from the core network of highly integrated, industry-first times commercial 3GDT, innovative use of softswitch server blade set, a flexible strategy for network sharing, and so on ... All this occurred in the same operator, who is the operator Telstra.

The experience of one: the rapid upgrading of network performance

Telecom Australia (Telstra) is Australia's leading telecommunications and information services company, is currently the country's largest mobile communications operator. Experience has shown that its operation, 3G network to be successful, we must give top priority to the user experience.

First of all, better than competitors in the Australian telecommunications network to promote their network coverage. In Australia and the vast country, from big cities to small cities, to the vast remote areas, population densities are very different from the coverage of not only the existence of national difficulty, and costly. A result, many Australians to good coverage of the network as an important element in the decision. When a comprehensive Telstra CDMA network to replace the original decision, only 10 months, the operator announced that its Next G? (HSPA) network covers more than 98% of Australia's population. This is an incredible achievement, Ericsson as sole supplier of HSPA mature quality program demonstrated the performance of super-class equipment, and a full range of services for the implementation of the capacity of high-speed high-quality completion of projects play an important role. In the four months after the opening of the next generation network, Telstra in Australia over the top of the site-specific installation and activation of Ericsson to expand the coverage of the software, a single base station to the coverage of 200 kilometers, to a large geographic area all 3G operations support.
Second, continuously improve the network performance. Network at the beginning, HSPA peak network download speeds up to 3.6Mbps, the second year of the beginning of the year on further to 14.4Mbps. December 5, 2008, Australia Telecom and Ericsson to work together to create an "industry first" - in the Next G network, the success of the opening of the commercial peak of up to 21Mbps network speed of the HSPA evolution of technology and the adoption of a new network of the world's first data. The improvement of technology as a new user broadband experience, a significant upgrade their Web browser and file download speeds, and even than many fixed-broadband connection even faster. Through the deployment of HSPA Evolution technology, operators will be able to significantly enhance the network capacity, and at the same time to reduce the provision of mobile broadband services cost.

Second experience: 2G and 3G network sharing

3G users and the rapid development of business to the core network at the same time brought great pressure, Telstra and Ericsson foresaw this situation, from the very beginning, based on a variety of innovative technologies, set up a public mobile core network 2G3G modern architecture.

In order to achieve the advanced flexible circuit 2G and 3G public mobile core network, Telstra has deployed mobile softswitch solution MSC Pool technology and in order to flexibly deal with all 2G and 3G traffic. In this structure, the use of nodes as possible to Ethernet transmission through low-cost, high-speed fiber optic interconnection of IP equipment. Through load balancing "resource pool" to establish a regional node, to achieve security and stability of large networks to enhance the core network integration.

Public in 2G and 3G mobile packet core network, the introduction of dual-access SGSN (Service GPRS Support Node) packet core network nodes to support data 2G3G function. This will not only save network resources, but also the use of the SGSN pool technology, enabling the establishment of an end-user can dynamically handle 2G/3G voice and data on changes in the demand for business networks.

MSC and SGSN pool pool design technology to optimize the network to improve network capacity of up to 25%, while saving operators OPEX.

2G3G network to core network integration to the public is not Next G? Network core network of the end of renovation project. With the support of Telstra announced the start of 21Mbps downlink speeds of up to HSPA +, the data flow will be rapid growth in the future. Telstra is expected in 2008 from the voice traffic by 2011 will grow by about 45% of data traffic to grow by 680%.


In the mobile voice, in order to support efficient implementation of the business transformation of the major networks to introduce a new generation of mobile switching servers. Telstra's core network of the mobile voice (currently 5 in the region) will be a new generation of servers to replace the future, that is used for the first time in the industry "MSC server blade set." MSC server blade set that is the next generation large-capacity mobile softswitch solution, just two cabinets to support the 8 million users, which will enhance the mobile softswitch to new heights.

Telstra in the planning of 3G networks, will be set to meet the needs of future business objectives and be fully considered in the implementation of the wireless network, core network construction and transformation process, using high-performance, high efficiency, the most scalable and future protection Mrs solution, the results of the growth in mobile broadband users, business development and income have been well proven.

High-performance network, the node capacity of a higher and more comprehensive network design can help reduce the number of nodes and optimize the site energy efficiency, thereby reducing capital and operating expenditures, while reducing energy consumption and follow-up of carbon dioxide emissions.

In addition, mobile data growth is giving full play to all kinds of data content and business advantages of wireless broadband. The telecommunications network in Australia, one each of the elements and operations are based on a nation-wide coverage, high-performance 3G network, that is, the user can reliably use of 3G technology, in the application process has always been to enjoy 3G network coverage and capacity to provide the speed and connectivity, all users become Telstra to maintain the key to loyalty.

Overall, Telstra user-centric to network-based products was a great success strategy, Telstra's experience shows that high-quality service and network operator's core competitiveness.
