目前关于个人通信还没有统一的、简明的定义,但关于个人通信概念的基本点却是一致的,其一,要把信息送到个人,即送到该终端时收信人一定在那里,能收到所传送的信息。其二,个人可以控制自己的通信业务。 为了实现个人通信,个人需要有随身携带的终端,有人将这叫做终端个人化。显然终端个人化是通过终端移动性实现的,终端移动性是指一个终端在移动中从不同的地点获取电信业务的能力,以及网路对该终端识别和跟踪的能力。 蜂窝移动通信系统主要是根据车载电话机进行设计的,所以使用手持机在小区边缘地区通话时,通话质量下降或不通。DCS1800、PCS1900、DECT、PHS等都是根据手持机进行设计的,因此这些系统都是可以提供个人通信业务(PCS)的 At present, there is no unified and concise definition of personal communication. However, the basic point about the concept of personal communication is the same. First, we must send the information to the individual, that is, the receiver must be there when it is sent to the terminal To send the message. Second, individuals can control their own communications business. In order to achieve personal communication, individuals need to have portable terminal, some people call this terminal personal. Obviously terminal personalization is achieved through terminal mobility, terminal mobility refers to the ability of a terminal to acquire telecommunication services from different locations while moving, and the ability of the network to identify and track the terminal. Cellular mobile communication system is mainly based on the car phone design, so the use of handsets in the cell edge of the area calls, the call quality decline or barrier. DCS1800, PCS1900, DECT, PHS and so on are designed according to the handset, so these systems are all capable of providing Personal Communication Services (PCS)
