Embodiment Construction

[0050] The invention adopts a new parallel calling mode, which enables the terminal based on the digital trunking system to allow the calling user to start speaking in a shorter time, and shortens the waiting time after the calling user presses the calling key.

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] As shown in Figure 3, the embodiment of the present invention is the process of using the CDMA network to call, including the following steps:

[0053] Step 301, the terminal initiates a call. This step includes the user pressing the call key to the terminal to send the call message to the system dispatching subsystem; The UI displays the "speak" interface, thereby notifying the user that it is possible to start speaking;

[0054] Specifically, this step includes:

[0055] (A) The user presses the calling key to notify the MC that the call is started, and the MC is ready to ca...

Abstract

The method comprises: before user end receives the 'speaking' authorization sent by scheduling subsystem of the system, the user end is permitted to speak. The invention can increase the call speed of user, and reduce the waiting time from pressing down the call initiation button to real speaking.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a method for quick calling of a terminal in a digital trunking communication system. Background technique [0002] The digital trunking communication system is an important branch of the mobile communication system, and it is a mobile communication system applied to group dispatching and command communication. Mainly used in the field of professional mobile communications, such as government departments, military, police, railways, water conservancy, civil aviation and steel logistics and other industries. [0003] As shown in Figure 1, the digital trunking communication system network mainly includes a trunking terminal 1, a base station subsystem 2, and a dispatching subsystem 3, in which: [0004] The cluster terminal 1 is a terminal device with cluster service functions, and is the main device for interacting between the cluster network and the user, hereinafter...
