Network Optimization Of PHS In Chaoyang

The PHS (Personal Handle System) has been a new way of mobile communication system in recent years. The PHS networks grow very quickly and now it has covered most cities of our country. The user is also increasing very rapidly, and about 80,000,000 people use it at the end of 2005. The PHS has become a new service-growing point as telecommunication companies such as China Telecom and China Netcom.In recent years, the PHS own the characteristic with more advanced technology, more powerful function, and more perfect service,while the output power and covered area of the cell-site have increased drastically in the PHS. At the same time, the PHS own its intrinsic weakness with the weak power's terminal, thin signal and limited area of the cell-site covered, frequent handover, and these features in the PHS make us to consider more on the distributions of constructions and the mobile population. And the technology also faces to other questions such as bad wave, low rate of successful call and drop quality of system. The reason lead to make a better PHS network is the center of our work.The article includes following parts. First, it introduces the hardware architecture and software of network management system of the PSC (personal handle system switch center). Second, it recommends the benefits and characters of the service, especially including cheap cost and good point to people's health which other mobile telecommunication system may not have. Third, the article discussed the system maybe in use for a long time after the license of the third generation mobile communications granted in our country after researched some experts'idea. Fourth, it derives the necessity to optimize the networks for the problems the system owns, such as system drop, high rate of wireless jam, bad wave, dial out for twice or more times, etc. The article also introduces...
