Embodiment Construction

[0035] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] As shown in FIG. 3 , a schematic diagram of a terminal call signaling interaction process in an embodiment of the present invention includes the following steps:

[0037] Step 301, the user presses the terminal call key, and after confirming the call start, the terminal turns on the terminal vocoder;

[0038] Step 302, the MC sends to the UI a message that the terminal is ready for voice buffering, and notifies the buffering task control unit to set the buffering start signal 1, which represents the following contents:

[0039] a. It is the overall sign of the cache application, and all cache judgments are based on this sign;

[0040] b. Only when the start buffering signal 1 is set, other buffering flags can be set;

[0041] Step 303, after the UI receives it, it sends a "speak" message prompt to the HS, a...

Abstract

The utility model discloses an optimization method of initial caching point when digital trunking communication system terminal applies the caching, user presses down the terminal call key to confirm the call, the terminal hardware control unit HS receives the ''speak'' information prompt transmitted by the control unit UI displayed on the terminal user interface, the ''speak'' interface is displayed while the caching task control unit is informed to start caching. The utility model has the advantages that optimizing the initial caching points of the terminals in the digital trunking communication system applying voice caching, thereby reducing voice delay effectively and meeting the requirement of the digital trunking user perfectly.

Description

technical field [0001] The invention relates to the field of digital trunking communication systems, in particular to a method for optimizing a buffering start point when a digital trunking communication system terminal uses buffering. 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 mainly includes a trunking terminal 1, a base station subsystem 2, and a dispatching subsystem 3, in which: [0004] Cluster terminal 1 is a terminal device with cluster service functions, and is the main device for interaction between the cluster netw...
