Specific embodiment
Illustrate a specific embodiment of the invention with reference to the accompanying drawings.In order to fully understand the present invention, it is described below and is permitted
More details, but to those skilled in the art, the present invention can also be realized without these details.
Referring to Figures 1 and 2, a kind of DMR hand platform eats dishes without rice or wine to write the intercom system of frequency, if including console 1, trunked base station 2 and
Dry hand platform 3.Wherein, console 1 and several hand platforms 3 are mutually communicated with trunked base station 2, and console 1 sends control signaling to collection
Group base station 2, trunked base station 2 carry out frequency point or group number parameter configuration to several hand platforms 3 using modified DMR air protocol.
Referring to Figures 1 and 2, as follows using the method that above-mentioned intercom system eats dishes without rice or wine to write frequency to DMR hand platform: first to existing
DMR air protocol carries out certain modification, allows to carry the configuration parameter of frequency point or group number；By the console of intercom system
1 sends control signaling to trunked base station 2, then utilizes modified DMR air protocol to several hands in system by trunked base station 2
Platform 3 carries out frequency point or group number parameter configuration.
One, it eats dishes without rice or wine to write the DMR signaling that frequency uses
Under cluster mode, the downlink AHOY signaling of control channel can be used for transmission state message, and format is as follows:
Wherein, Service_Options_Mirror is used for the actual value of definition status message.And define Service_
The value of Options_Mirror is represented to hand platform 3 and updates group number information when being 29, define Service_Options_Mirror's
Value is represented to the frequency point information under the update cluster mode of hand platform 3 when being 30, the value for defining Service_Options_Mirror is
The frequency point information being represented to when 31 under the update transfer of hand platform 3 or direct mode operation.
The frequency point information and group number information that need to be updated with the downlink UDT signalling hand platform 3 of control channel, one complete
UDT letter disappears to be made of multiframe signaling, respectively includes 1 UDT signaling head frame, 0 to 3 UDT intermediate frame, 1 UDT end frame.It
The data of 46 bytes can at most be transmitted.
The UDT signaling head frame format of DMR is as follows:
The UDT intermediate frame of DMR is 1/2 code rate without confirmation data frame, and format is as follows:
The UDT end of signaling frame format of DMR is as follows:
Two, eat dishes without rice or wine to write the process of eating dishes without rice or wine of frequency
As depicted in figs. 1 and 2, opponent's platform 3 carries out the Business Stream of eating dishes without rice or wine eated dishes without rice or wine to configure frequency point, group number information is arranged under group system
Journey is as shown in Figure 2.
Specifically writing frequency, steps are as follows:
(1) console 1 sends the AHOY signaling that Service_Options_Mirror state value is 29 or 30 through trunked base station 2
To hand platform 3.
(2) in response, the C_ACKU signaling for reflecting oneself state is transferred to console 1 through trunked base station 2 by hand platform 3.
(3) if C_ACKU response signal indicates that mobile phone is currently at the state of settable frequency point or group number, console 1 is passed through
The UDT multiframe signaling for carrying the configuration parameter is sent in one's hands 3 by trunked base station 2.
(4) hand platform 3 is reconfigured according to frequency point or group number of the configuration parameter to itself, then responds C_ACKU again
Signaling, expression have been received by configuration parameter and are set to function.
