| On current telecom industry, universal service has reached a huge mount of achievement. But universal service still is the focused topic, because the issue is upgraded from the unbalance of basic voice to complete digital issue. The customer and content of telecom service is changing and the depth and scope is expanding with the environment. Some responsible person of information industry department has mentioned that universal service is very important in the layout of "eleven-five" plan. So far, there are several ten thousand countries don't have phones, so universal service need to be improved, the task still has a long way to go.The difficulty of telecom service is communication in county, but what is it? There are several reasons. Firstly, the cost of telecom constructing is very high and is slow reclaimed. Secondly, everyone will install the telephone, but they use it less if we develop it fast and the benefit is low. Thirdly, the technology system doesn't suit universal service. Lastly, there isn't managing innovation. In short, technology invocation, the falling constructing cost and managing innovation the key point to the universal service. How to us the lowest cost, the smallest marking disturbing and lowest financial affording to implement universal service is very import task which need us to solve.There are several traditional voice accessing ways including copper cable, remote user module, optical fiber and wireless accessing etc. Telecom operators such as china telecom, Netcom and Railcom which have the license of telephone should use xDSL technology based on copper cable when they develop broad band service in order to using copper cable resource. The accessing way of "FTTx plus LAN" should be used for some new developing region, new slap-up building, business building, office building and group customer. The new telecom operator such as North telecom should use wireless accessing technology based on 3.5 G and 2.6G which has no accessing resource and want to develop customer. The telecom operators use PHS and SCDMA to develop customer in order to compete with mobile operator. The accessing market is the competition and existing of old and new technology, several transmitting mechanism and different application services.So, the article is focus on application of technology for telecom universal service in county. It will compare the existing technology, analyze the corresponding factors related to technology, aim on the background and environment of county communication by Zhejiang Telecom and analyze the mature of technology, the flexibility of user requirement, the cost of constructing network and the usage of existing network resource. |
