Dual-band Network Parameter Optimization Method Of Adjustment

With the booming of Chinese economy, the communication network of GSM mobile has experienced rapid growth in the development of mobile phone penetration rates steadily increasing, growing competition among carriers, rates continue to drop, telephone traffic climbing, lagging the increase in network capacity growth in business volume. The telephone traffic of Changchun rose rapidly, it works in the case of high location update, highlighting issues such as dual frequency switching. By analyzing the first half of 2009 group net test, the impact of Changchun mobile DT test switch rate is a major cause of the whole network there are more location update. How to reduce location updating as a result of the called number is not connected to improve the DT test the switch rate, is now an urgent need to solve network problems. At the same time not likely to cause frequent switching frequency dropped calls, increase the signaling load between the Council and will increase the amount of location updating.The communication networks of GSM mobile, compared with the fixed telephone network PSTN, signaling significant increase in traffic, in addition to regular calling, called Voice of the signaling load, needs to increase the number of mobile network-specific signaling load, such as short messages, location update, handoff, and user authentication. High signaling load will affect the safe operation of network elements, in small and medium telephone traffic under normal network element, in the case of high telephone traffic network capacity may become the bottleneck. The signaling load, the main called voice, messaging and other services to bring the signaling traffic and the traffic model mainly related to mobile phone users more often the greater the signaling flow, moving the company's operating income more, so need to improve This part of the signaling traffic ratio. The location update, handoff and user authentication, called the signaling process is mainly based voice, messaging and other business services, take up a lot of network resources, while not result in any revenue. This network of telephone traffic in the present context of rapid growth, through the location area optimization and dual parameter optimization, reducing the location update frequency network to switch between volume and frequency, reduce non-operational signaling overhead, makes the network capacity more and more revenue growth for the business.
