Terminal device under intermediate station.
It should be noted that the terminal device in the present invention can be hand-held station, Vehicle mounted station etc..
Technical solution of the present invention is further described below by way of specific DMR systems：
As shown in figure 3, by taking 4 intermediate stations as an example, a terminal device is connected under each intermediate station, when terminal device 1 is sent out
When playing calling, No. 1 intermediate station receiving calling signal is simultaneously sent to No. 2 intermediate stations, and No. 2 intermediate stations are sent to No. 2 terminal devices and 3
Number intermediate station, No. 3 intermediate stations are sent to No. 4 intermediate stations and No. 3 terminal devices, and No. 4 intermediate stations are sent to No. 4 terminal devices.By
This can realize that 2,3, No. 4 terminal devices can simultaneously receive calling, expand terminal and set when terminal device 1 initiates to call
Standby 1 scope that can be called.
Terminal device 1 in the marginal position end identical, in an intermediate position with the mode that terminal device 4 initiates calling
End equipment 2 is identical with the mode that terminal device 3 initiates calling.
By taking terminal device 2 as an example, when terminal device 2 initiates to call, the receiving calling signal of intermediate station 2 is simultaneously sent to transfer
Platform 1 and intermediate station 3, intermediate station 1 are sent to terminal device 1 after receiving call signal, and intermediate station 3 is sent to after receiving call signal
Terminal device 3 and intermediate station 4, intermediate station 4 relay to terminal device 4, and calling is initiated this completes No. 2 terminal devices
When, remaining 1,3, No. 4 terminal device receives the process of calling.
Can there is problems with actual use：If using fixed frequency as transmission channel, with the He of intermediate station 1
As a example by intermediate station 2, the transmission frequency of intermediate station 1 is F1, and receives frequency is F2, if intermediate station 1 and 2 will carry out signal transmission,
The receives frequency of so intermediate station 2 is necessary for F1, and transmission frequency is F2, so can just carry out signal transmission, but due in
Turntable is dual-mode, and when intermediate station 1 initiates to call, intermediate station 2 will be forwarded to intermediate station 1 after receiving call signal, in
Turntable 1 continues to be transmitted to intermediate station 2 after receiving the call signal of intermediate station 2, and this has resulted in intermediate station 1 and intermediate station 2 is mutual
The call signal of Phase Receiver other side simultaneously continues forwarding, it is impossible to stop, therefore can not use fixed frequency as transmission channel, in order to
Such case is avoided to occur, the embodiment of the present invention plans the frequency of intermediate station 1 and 2 as shown in table 2 again：
Table 2
When just starting working, intermediate station 1 and intermediate station 2 are in scanning mode, i.e. intermediate station and monitor F2 frequencies and F3 simultaneously
Signal in frequency, if detect have in a certain frequency call signal will continue on that frequency receive.So can be
Avoid the occurrence of continuously transmitting what cannot be stopped.
Specific calling procedure is as follows：
When terminal device 1 issues 1 call signal of intermediate station, intermediate station 1 is received in F2 frequencies, then by F1 frequencies
Send, then intermediate station 2 is received in F1 frequencies, sent in F3 frequencies, then terminal device 2 receives terminal device 1 and sends out
The call signal sent.
When terminal device 2 issues 2 call signal of intermediate station, intermediate station 2 is received in F4 frequencies, then by F3 frequencies
Send, then intermediate station 1 is received in F3 frequencies, sent in F1 transmissions, then terminal device 1 receives terminal device 2 and sends out
The call signal sent.
So it is achieved that 2 cascades of intermediate station to expand the coverage area so that the call coverage of terminal device expands.
When 4 intermediate stations are cascaded, scanning mode is in when just starting working, its frequency relation planning such as table 3
It is shown：
Table 3
Terminal device 1 and the calling procedure of terminal device 2 are somewhat different, and specific calling procedure is as follows：
When terminal device 1 initiates to call, intermediate station 1 is received in F2 frequencies, is sent in F1 frequencies afterwards, in
Turntable 2 is in scanning mode, is just sent by F3 frequencies after the signal of scanning to F1 frequencies, then the He of terminal device 2
Intermediate station 3 receives the signal of intermediate station 2, and intermediate station 3 issues terminal device 3 and intermediate station 4 after receiving signal by F5 frequencies, in
Turntable 4 is sent to terminal device 4 after being received in F5 frequencies by F7 frequencies, and the calling that such terminal device 1 is initiated is in transfer
Platform 1,2,3,4 can be received below.
When terminal device 2 initiates to call, intermediate station 2 is received in F4 frequencies, is sent in F3 frequencies afterwards, in
Turntable 1 is in scanning mode, is just sent by F1 frequencies after the signal of scanning to F3 frequencies, and then terminal device 1 connects
The signal of intermediate station 1 is received, intermediate station 3 is also at scanning mode, is issued by F5 frequencies after the signal of intermediate station 2 is received
Terminal device 3 and intermediate station 4, intermediate station 4 are sent to terminal device 4, such terminal after being received in F5 frequencies by F7 frequencies
The calling that equipment 2 is initiated can also be received below intermediate station 1,2,3,4.
Similar to the calling procedure of terminal device 1, the calling procedure of terminal device 3 is similar to the calling procedure of terminal device 4
In the calling procedure of terminal device 2.
When being so achieved that any one station terminal equipment initiates calling, terminal device below remaining intermediate station can be with
Signal is received, the scope that script covers an intermediate station is expanded to four scopes of intermediate station.
Supplement is also needed to, each terminal device has signal identification function, can judge whether is the call signal that receives
Calling oneself, by detection it is determined that whether participating in calling procedure so after terminal device receives call signal.
Method provided in an embodiment of the present invention can realize that terminal device 1 individually calls other mistake for terminal device
Journey, it is also possible to realize terminal device 1 while calling the process of several terminal devices, can also realize terminal device 2 while exhaling
It is the process of all terminal devices under DMR systems where it；Passed through after certain terminal device receives the signal that intermediate station is issued
Cross parsing to find when oneself needing not participate in calling, that is, keep mourning in silence.
One of ordinary skill in the art will appreciate that：Realizing all or part of step of above method embodiment can pass through
Programmed instruction related hardware is completed, and foregoing program can be stored in computer read/write memory medium, and the program exists
During execution, the step of including above method embodiment is performed；And foregoing storage medium includes：ROM, RAM, magnetic disc or CD
Etc. it is various can be with the medium of store program codes.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
