Class B and Class C district band_preference = GSM900 [1], and then consider the use PBGT different switching algorithm to control dual-band network traffic flows. With the rapid development of digital mobile communications, the network needs to grow rapidly. On GSM900MHz band limited frequency resources, China Mobile Communications GSM network in some areas have been introduced into the common network of the GSMl800 and GSM900 system. Networking early, GSM1800, Community Access, as well as switching a higher priority, so when the trans-regional side of the border has GSMl800 district, adjacent to a different location area on the other side only GSM900 cell. So that the problem of cell phone jammer can be found out timely.
As shown in Figure 1, the traffic at the junction region by a large number of the GSMl800 the base station absorbed. This imbalance, resulting in one hand, GSM1800 base station is more busy, on the other hand the boundaries of residential users only GSM900 base often in a non-normal roaming, especially when a call is local call meter roaming charges and long distance arising from the bill dispute. When this happens in inter-provincial boundary, in addition to the bill dispute, also accompanied by a large number of dropped calls. In these circumstances, reasonable traffic sharing is very important. Past the practical application of the above problems commonly experience adjustment method, which requires a large number of measured, and approaching the best value for a long time.
Practical application in the border base stations of GSM dual-band system, has been good business to share the effect. There are two points worth noting, first, the same location area adjacent to the base station parameters should also make the appropriate adjustments; mobile phone users can select a fixed-band access networks, should be recommended to the user selected band. GSM wireless network to maintain the common problems and treatment methods. Wireless network over a broad factors affect the communication quality, related to the equipment is more extensive, complex and implicit. According to different sources, you can maintain a frequently encountered problem is divided into: equipment failures, three categories of interference problems and database parameters. Mobile communication equipment failure includes not only the mobile communication device itself (referred to as the "master") hardware, software failures.
