GSM is based on narrowband TDMA standard that allows radio frequency in a group call at the same time 8. GSM80 during the rise in Europe, put into use in 1991. The end of 1997, has

8、 operations in more than 100 countries, Europe and Asia has become the standard in fact, that by 2001, the worlds 162 countries have already built a 400 GSM communications network. But the GSM system capacity is limited, users in the network overload, it had to construct additional network facilitie

9、s. What is gratifying is that GSM performance in other areas, which in addition to providing a standardized list and signaling systems, but also opened up some of the more intelligent of the business such as international roaming and so on. The convenience of GSM mobile phone is that it provides a s
