The trunking communication users, such as the government and the business sector which often use the group command and dispatch services, will be a growing concern ,while the public mobile communication gets the rapid development. A shared construction of digital trunking professional communication network is to be the new market growth after the public mobile communications. The development of the public mobile communication takes the convenience to individuals, but the construction of digital trunking technology brings the government institutions and enterprises efficiency. The trunking communication is widely used in China's large-scale enterprises and groups, the law enforcement sector, has played a positive role in safeguarding the producing, command and dispatching. At present, these systems are built for their own. Though this mode has some positive role in internal communications, there are also a lot of drawbacks, such as, the high cost of network construction, the limited network coverage, the mismatch between network capability and the usage of terminal users, the high cost of network maintenance, the low level of technical support and the poor capability of evolution and upgrade. Most of these systems use the outdated analog technology. These systems use too many different types' modes, can not be upgraded to the large-scale networks. Their capability is small. The wireless recourses are seriously wasted. The whole socio-economic costs of China's trunking communication systems are very high, resulting in a waste of national resources. In order to get a healthy and orderly development, the national authorities strengthen the support and management of trunking service. They clearly classify the trunking service to belong to the second largest category of the national basic public communications in 2003, stop the approval and construction of analog trunking systems by the end of 2005. They recommend the national basic communications carriers to construct the shared trunking systems to meet the trunking service needs of the units and sectors. Thus, these units only need to purchase the terminals without further building their own networks. The basic carriers construct the shared trunking systems to bring the following advantages: the shared frequency, the shared channel, the shared coverage, the shared communication service. This mode is suitable for large-scale network's construction, brings the high frequency utilization to meet the users' capability demand, brings more richer services.But the shared digital trunking network operation is facing the problem how to organic combine the universality of the shared trunking network and the exclusivity of the professional trunking network . By discussing the important functions of the dispatching manager in the digit trunking network, this paper provides the solution to modify the current dispatching manager of B/S version to reach the perfect combination of universality and exclusivity.
