In the mobile communication network 100 as described above, the voice call connection is performed through a circuit switching method. This is because, due to the nature of a voice call connection, real-time communication (for example, Minimization) must be realized.

There is a wireless data communication network as a wireless communication network that is roughly divided into the mobile communication network 100. The wireless data communication network currently being serviced or developed may be classified into six types, Packet communication network, TRS (Trunked Radio System) network, and satellite communication network. A cellular-based communication network and a wireless dedicated packet communication network corresponding to the present invention among the above-mentioned wireless data communication networks will be described as follows.

The Network Control Center (NCC) is responsible for the operation, management and maintenance of the network elements. The data terminal is divided into a fixed data terminal and a wireless data terminal. The fixed data terminal is connected to the local exchange through a fixed link, and the wireless data terminal is connected to the wireless base station through a wireless channel.

In the wireless dedicated packet communication network, the dedicated packet communication is performed through a packet switching method. This is because it is necessary to ensure the reliability of communication (for example, communication error detection and data retransmission, etc.) . As a result, the wireless dedicated packet communication network can not realize high quality voice communication unless the reliability of data communication is guaranteed in real time.

Currently, the wireless dedicated packet communication system commercialized to implement the wireless dedicated packet communication network includes DataTAC of Motorola of America and Mobitex of Ericsson of Sweden. In Korea, Packet communication systems are all commercialized.
