GSM network optimization of a new generation of high-performance wireless solutions-GSM, mobile netw

Since 1994 in Jiaxing, Zhejiang building Asia's first GSM mobile network has more than ten years of continuous development, Shanghai Bell Alcatel GSM network, advanced, reliable, mature and excellent security services in the mobile market sufficiently validated , GSM network has more than 20 provinces in the country by a large-scale application.

For new market conditions and new demands on the network, GSM, Alcatel Shanghai Bell continued to increase research and development, independent innovation, introduced a new generation of GSM wireless solutions, to achieve cost-performance GSM network construction and development of high stability, high scalability and high efficiency, which includes capacity solution, the new rural networks and next-generation high-capacity solution for highly integrated BSC, TwinTRX double carrier frequency and so on.

GSM wireless capacity solutions

For the market conditions and new demands on the new network, Alcatel Shanghai Bell launched a GSM wireless capacity solution to achieve low cost and high performance GSM network construction and development.

1. Dual-band network The introduction of DCS1800 dual-band network

mainly to solve the problem of limited GSM900 frequency. Typically, the dual-band network is GSM900 network-based, GSM1800 network added to build the net, use of superposition of two networks, GSM or DCS complementary coverage of the shortage of high telephone traffic mitigation dense metropolitan area wireless channel has become tighter situation. The same time, GSM1800 and GSM900 network system in the system, project implementation, network maintenance and support services such as more consistent, so use GSM900/1800 dual-band operation, can cost-effectively solve the network capacity needs.

Shanghai F1 track in participating, National Games in Nanjing, Tianjin, China Unicom and other dual-band network construction, Alcatel Shanghai Bell worked out a series of dual-band network engineering experience, with rich experience and dual-band dual-band network optimization switching algorithm so that the two dual-band mobile phone network layer switching between the normal and reasonable flow, a reasonable distribution of dual-band network carrying telephone traffic.

2. Semi-rate function

Half-rate technology, the introduction, can further improve the utilization of network resources, in particular the sudden increase in the wireless network so emergency services support capabilities, but the operators have to call attention to high-end user experience, the proposed park in the school as much as possible , ad hoc meetings, emergency communications, the demand function to open a half rate, or degree of importance for the user to provide customized semi-rate program, to ensure that high-end customers and prepaid brand of high-value customers preferred full-rate channel.

In Shanghai F1, Nanjing National Games and other major events, the half-rate emergency communication technology as an open, mainly used in the main hall and exit to enter the two words when service starts automatically during the height of HR technology absorption Call , it works in low-load conditions, the system will automatically revert to the decision network load full speed, in order to obtain resources, inputs and network quality of win-win situation.

Campus projects in Shaanxi, the targeted business volume, traffic density and high school area, we opened a half-rate technology, effectively reduce the network congestion, economic and social benefits to achieve the maximization of the network.
