Abstract

A method of data a communication includes: determining, by a first terminal, an idle channel, and transmitting a data handshake request carrying interruption information on the idle channel, wherein the interruption information at least includes a call indication of an interrupted traffic channel; receiving a data handshake response transmitted by a repeater; when a data handshake response is of a type allowing interruption, jumping to a traffic channel designated by the repeater according to a channel jumping indication included in the data handshake response; and when determining that a second terminal occupying the traffic channel to make a call interrupts the call and releases a resource of the traffic channel, initiating a call on the traffic channel. The embodiments of the present invention can interrupt the call of the transmitting terminal and release the channel resource, and have strong flexibility and high efficiency.

Claims

1. A method for data communication applied to a first terminal, comprising:

determining an idle channel, and transmitting a data handshake request carrying interruption information on the idle channel, wherein the interruption information at least comprises a call indication of an interrupted traffic channel;

receiving a data handshake response transmitted by a repeater;

when a data handshake response is of a type allowing interruption, jumping to a traffic channel designated by the repeater according to a channel jumping indication comprised in the data handshake response; and

when determining that a second terminal occupying the traffic channel to make a call interrupts the call and releases a resource of the traffic channel, initiating a call on the traffic channel.

2. The method according to claim 1, wherein the determining that the second terminal occupying the traffic channel to make a call interrupts the call and releases resources of the traffic channel comprises:

when a voice end frame transmitted by the second terminal is detected on the traffic channel, determining that the second terminal occupying the traffic channel to make a call interrupts the call and releases the resource of the traffic channel, wherein the voice end frame is configured to show that the second terminal interrupts the call and releases the resource of the traffic channel;

or,

when a handshake end frame broadcast by the repeater is detected on the traffic channel, determining that the second terminal occupying the traffic channel to make a call interrupts the call and releases the resource of the traffic channel, wherein the handshake end frame is configured to indicate that the repeater keeps the traffic channel for the first terminal after the second terminal releases the resource of the traffic channel.

3. The method according to claim 1, wherein the determining the idle channel comprises:

determining a preset designated interruption channel as the idle channel;

or,

when determining that a same-station call is received, determining a same-frequency idle channel of the traffic channel receiving the call as the idle channel;

or,

determining an idle channel of a free repeater broadcast by a system as an idle channel;

or,

when determining that a cross-station call is received, determining a channel receiving the cross-station call as the idle channel.

4. The method according to claim 1, further comprising:

when an indication for interrupting a call is detected on an adjacent channel of the traffic channel initiating the call, transmitting the voice end frame to interrupt the call and release the resource of the traffic channel.

11. An apparatus for data communication, comprising:

a transmitting unit configured to determine an idle channel, and transmit a data handshake request carrying interruption information on the idle channel, wherein the interruption information at least comprises a call indication of an interrupted traffic channel;

a receiving unit configured to receive a data handshake response transmitted by a repeater;

a jumping unit configured to, when the data handshake response is of a type allowing interruption, jump to a traffic channel designated by the repeater according to a channel jumping indication comprised in the data handshake response; and

a calling unit configured to, when determining that a second terminal occupying the traffic channel to make a call interrupts the call and releases a resource of the traffic channel, initiate a call on the traffic channel.

12. (canceled)

13. An apparatus for data communication, comprising a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by one or more processors containing instructions for performing following operations:

determining an idle channel, and transmitting a data handshake request carrying interruption information on the idle channel, wherein the interruption information at least comprises a call indication of an interrupted traffic channel;

receiving a data handshake response transmitted by a repeater;

when a data handshake response is of a type allowing interruption, jumping to a traffic channel designated by the repeater according to a channel jumping indication comprised in the data handshake response; and

when determining that a second terminal occupying the traffic channel to make a call interrupts the call and releases a resource of the traffic channel, initiating a call on the traffic channel.
