Normally, the terminal must first be powered on to perform the registration process, one form of mutual authentication and the other form of network device acquisition of some basic information about the terminal. .. After that, the terminal has been idle all the time. When the terminal switches from the idle state to the connected state, it is necessary to start random access to the network device, and the terminal can send / receive data to / from the network device only when the random access is completed.

For example, when the dedicated information includes all the above information related to the connection establishment of the terminal, the terminal and the network device send and receive a connection establishment request, for example, a connection establishment request message, a connection establishment message, and a connection establishment completion. It is not necessary to send and receive messages and the like. The terminal may add various information configured for the terminal by the network device to the random access response message. If the dedicated information includes only the magnitude and format of the first signaling transmitted, the network device knows the magnitude and format of the first signaling transmitted thereafter, but the terminal device is still with the network device. It is necessary to send and receive connection establishment requests. When the dedicated information includes only the content in the connection establishment request message, the terminal may omit the connection establishment request message in the process of transmitting and receiving the connection establishment request to and from the network device thereafter. The process of accessing the network device of the terminal may differ depending on the content included in the dedicated information, and the technical proposal for the terminal to access the network device at higher speed or more flexibly is described in the embodiment of the present invention.
