Abstract
The invention discloses a voice and data synchronous transmission method at a DMR (digital mobile radio) terminal. In the method, when the DMR communication terminal transmits voice, one super-frame is sent every 360MS, wherein, 48-bit in the middle of the F-frame of each super-frame transfers invalid data (namely an invalid data area); and the 48-bit invalid data area in the middle of the F-frame of each super-frame is used for transferring data or controlling information. The voice and data synchronous transmission method has the beneficial effects that the 48-bit invalid data area of the F-frame is used for transferring the data or controlling the information, thus achieving the voice and data synchronous transmission effect, saving channels which are originally used for transferring the data and improving utilization ratio of the channels.
Description
Technical field
The present invention discloses the same transmission method of a kind of speech data, the same transmission method of particularly a kind of DMR terminal speech data.
Background technology
DMR is the abbreviation of Digital Mobile Radio; It is the consensus standard that European digital handset uses; When the regulation communicating terminal is launched voice superframes in the DMR agreement; Each voice superframes comprises the ABCDEF speech data frame; Wherein the centre of F frame is the invalid data of 48BIT; Transmission can cause the waste of channel in this way.
Summary of the invention
Cause the shortcoming of channel wastage when launching voice superframes to the above-mentioned DMR communicating terminal of mentioning of the prior art; A kind of new same transmission method of DMR terminal speech data is provided among the present invention; It utilizes 48bit invalid data district's Data transmission or control information in the middle of the F frame, to reach the purpose that makes full use of channel.
The technical scheme that the present invention solves its technical problem employing is: the same transmission method of a kind of DMR terminal speech data; When this method is launched voice for the DMR communicating terminal; Every 360MS sends a superframe; What the 48bit in the middle of the F frame of described each superframe transmitted is the invalid data district, utilizes the middle 48bit invalid data district's Data transmission or the control information of F frame of each superframe.
The invention has the beneficial effects as follows: the present invention utilizes the 48BIT invalid data district of F frame to come Data transmission or control information, reaches the effect of speech data simultaneous interpretation, and can save down the former channel that is used for Data transmission, improves channel utilization.
To combine accompanying drawing and embodiment that the present invention is further specified below.
Description of drawings
Fig. 1 is the superframe data structure sketch map in the DMR communicating terminal voice call process among the present invention.
Fig. 2 forms sketch map for the superframe in the DMR communicating terminal voice call process among the present invention.
Fig. 3 is F frame data structure sketch map among the present invention.
Fig. 4 is 48bit data structure sketch map in the middle of the F frame among the present invention.
Embodiment
Present embodiment is the preferred embodiment for the present invention, and other all its principles are identical with present embodiment or approximate with basic structure, all within protection range of the present invention.
Stipulate in the DMR agreement; The DMR terminal is superframe of every 360ms emission in the voice call process, and please referring to accompanying drawing 1 and accompanying drawing 2, each superframe comprises six speech data frames of ABCDEF; What the middle 48BIT of conventional F frame transmitted is invalid data (please referring to accompanying drawing 3), i.e. invalid data district.Among the present invention, utilize the middle 48bit invalid data district's Data transmission or the control information of F frame of each superframe, reach the effect of speech data simultaneous interpretation.Data among the present invention or control information can be the information such as other control informations at GPS information, key information or DMR terminal, perhaps also can be speech data etc.
The present invention utilizes the 48BIT invalid data district of F frame to come Data transmission or control information, reaches the effect of speech data simultaneous interpretation, and can save down the former channel that is used for Data transmission, improves channel utilization.
Claims (1)
1. same transmission method of DMR terminal speech data; It is characterized in that: when described speech data is launched voice with transmission method for the DMR communicating terminal; Every 360MS sends a superframe; What the 48bit in the middle of the F frame of described each superframe transmitted is the invalid data district, utilizes the middle 48bit invalid data district's Data transmission or the control information of F frame of each superframe.
