Abstract

A method for realizing a fast answer of a terminal in a digital trunking communication system comprises: after receiving a channel assignment message signalling from a system side, a main control device of the terminal establishes a service channel, determines a call type, and executes a voice mode flow when the call is a normal voice call, or sends a service interface display message to a control chip of the terminal when the call is a trunking call; and the control chip, according to the service interface display message sent by the main control device, displays a service interface and begins to answer voice information. A terminal in the digital trunking communication system is further provided, which comprises a main control device and a control chip. The terminal in the digital trunking communication system and method for realizing the fast answer thereof adapt to the requirements for a fast access and display of the terminal in the digital trunking communication system and better meet the requirements of the digital trunking users.

Claims

1. A method for fast answering a trunking call in a digital trunking communication system, comprising:

establishing, by a main control device of the terminal, a service channel after receiving a channel assignment message signalling from a system side;

determining, by the main control device, whether a call from the system side is a trunking call or not;

sending, by the main control device, directly a service interface display message to a control chip of the terminal when determining that the call is a trunking call; and

displaying, by the control chip, a service interface according to the service interface display message, answering the call, and playing voice messages sent by the system side.

2. The method of claim 1, wherein the main control device determines whether a call from the system side is a trunking call or not according to contents of an assignment mode field in the channel assignment message signalling.

3. The method of claim 1, wherein the terminal is a mobile phone or a vehicle mounted radio station.

6. The method of claim 2, wherein the terminal is a mobile phone or a vehicle mounted radio station.

4. A terminal in a digital trunking communication system, comprising a main control device and a control chip, wherein:

the main control device is configured to;

establish a service channel after receiving a channel assignment message signalling from a system side;

determine whether a call from the system side is a trunking call or not; and

send directly a service interface display message to the control chip of the terminal when determining that the call is a trunking call; and

the control chip is configured to display a service interface according to the service interface display message, answer the call, and play voice messages sent by the system side.

5. The terminal of claim 4, wherein the terminal is a mobile phone or a vehicle mounted radio station.
