在不断扩展的移动电话市场中,手持移动电话形成了一股稳定增长的推动力。我们已走上了个人通信的发展道路。手持电话的使用将意味着空中接口的业务量的可观增长,这主要是由于两个原因,一是用户数量会越来越大,对网路质量的要求也越来越严格;二是个人电话将足以取代有线电话。 本文介绍了与个人电话的引入相关的问题,并提出了一些可能的解决方法,其中几种方法已开始实用或在新的数字系统的实现中已得到初步认识,这些系统已在欧洲、北美和日本实现,它们所提供的功能甚至可以满足个人通信的要求。
In the expanding mobile phone market, handheld mobile phones have created a steady growth driver. We have embarked on the path of personal communication development. The use of handsets will mean a substantial increase in traffic over the air interface, mainly due to two reasons, one is the growing number of users and the stricter requirements for network quality; the second is the use of personal telephones Will be enough to replace the wired telephone. This article describes the issues related to the introduction of personal telephones and suggests possible solutions. Several of these approaches have become practical or have been initially recognized in the implementation of new digital systems already in place in Europe, North America and In Japan, the functions they provide can even meet the requirements of personal communication.
