In order that those skilled in the art more fully understand the present invention program, below in conjunction with of the invention real
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, shown
So, described embodiment is only the embodiment of a part of the invention, rather than whole embodiments.
Based on the embodiment in the present invention, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, should all belong to the scope of protection of the invention.
The embodiment of the present invention is applied in police Digital Clustering PDT system standards, and PDT systems include base
Stand and PDT terminals, wherein, base station can for digital transmission trunked base station, numeral specialty trunked base station,
The trunked base stations such as the professional small cluster of PDT numerals；PDT terminals can be digital handset, digital in-vehicle platform
Etc. equipment.
In existing trunked communication system, as shown in figure 1, base station includes：Base station controller, channel
Machine, combiner and antenna etc..Wherein, channel device refers to and in a wireless communication system, baseband signal is turned
Become the emitter of radiofrequency signal and receive radiofrequency signal from antenna transmission system and be restored to connecing for baseband signal
The unit equipment of receipts machine.
The modulated signal that multiple channel devices send such as is schemed by after combiner combining, launching from antenna
Shown in 1, the modulated signal that channel device 1, channel device 2, channel device 3, channel device 4 send passes through combining
Device sends after being combined from antenna.Group system for channel device quantity more than 4 is general to use
Combiner, combiner includes multiple wave filters, each wave filter one frequency of correspondence, i.e., for a filter
For ripple device, the signal of only one of which frequency can pass through, and this is accomplished by each channel device in trunked communication system
The frequency supported with each wave filter respectively of working frequency correspond, as shown in figure 1, channel device 1
Working frequency is identical with the frequency that wave filter 1 is supported, working frequency and the wave filter 2 of channel device 2 are supported
Frequency it is identical.
General, only one of which control channel in a trunked communication system can have multiple business to believe
Road, control channel is used for bearer control signalling, such as, the public letter that base station sends to all mobile stations
Control information required for breath, the foundation calling between base station and mobile station etc..Traffic Channel is used to carry
Business datum between base station and mobile station, such as speech data or Media Stream etc..Control channel can be
The working frequency of channel device 1, or the working frequency of channel device 2, or other channel devices
Working frequency, this working frequency for control channel working frequency be control channel machine；Similarly, business
The channel device of channel is referred to as Traffic Channel machine.
In existing PDT systems, control channel machine will be constantly in continuous emission state when working, and industry
Business channel device only business is just in running order during carrying out.If being always maintained at this kind of working condition
Constant, then the life-span of control channel machine will be significantly shorter than Traffic Channel machine, the failure that can increase system is general
Rate.
It is therefore desirable to have rational channel device handover mechanism, is capable of the service life of balanced each channel device,
In the premise of the normal work for not influenceing system and terminal, taking over seamlessly for control channel machine is realized.
In existing PDT systems, if it is desired to change if control channel machine, there is following 2 kinds of modes：
Mode one：Control channel frequency changes：
1st, signaling under base station controller (Trunking Station Controller, TSC), original is controlled
Channel device processed is configured to Traffic Channel, while former Traffic Channel machine is configured into control channel；
2nd, after channel device is connected to instruction, power amplifier is controlled into flag set.Control channel power amplifier is normally opened, empty
Idle channel closes power amplifier；
3rd, now control channel frequency has changed, and terminal needs to re-search for control channel to reach the standard grade.
Mode one will cause control channel frequency to be changed, and shortcoming is as follows：
(1) all terminals positioned at control channel are required for rescaning control channel, and re-search for control
Business cannot be initiated during channel processed；
(2) terminal positioned at Traffic Channel jump back to former control channel (having turned into Traffic Channel now) can
Energy meeting traffic affecting is carried out.
Mode two：Control channel frequency is constant：
1st, former control channel machine power amplifier, signaling under base station controller TSC, by former control channel are closed
Machine is configured to Traffic Channel, while former Traffic Channel machine is configured into control channel；
2nd, reset channel device frequency, by two channel device frequencies exchange, and manually change channel device with
The radio frequency line of Combiner port connection, makes channel device launching frequency consistent with Combiner port frequency；
3rd, after channel device is connected to instruction, power amplifier is controlled into flag set.Control channel power amplifier is normally opened, empty
Idle channel closes power amplifier；
4th, now control channel frequency is although unchanged, but terminal still needs to re-search for control channel to reach the standard grade.
Because combiner is to determine frequency combiner in base station in existing PDT systems, the shortcoming of mode two is as follows：
(1) need to change the radio frequency line that channel device is connected with Combiner port manually, it is impossible to which realization is cut automatically
Change；
(2) it is not seamless switching due to the method although control channel frequency is unchanged, therefore terminal
Control channel can cannot be searched for some time, influence business is normally initiated.

From Traffic Channel select a run time it is most short, and the free time Traffic Channel machine as to be switched
Traffic Channel machine.
Optionally, base station is not necessarily the most short idle business channel, or root of selection run time
It is tactful in a balanced way according to each channel device run time, and comprehensively other operating index of each channel, carry out sky
The selection of not busy Traffic Channel.
Preferably, when control channel wheel is changed, the period of heavy traffic is preferably avoided, therefore, in base station
Selection one suitable Traffic Channel machine as before to be switched Traffic Channel machine, it is necessary to first judge now
Whether whether business is busy, that is, judge the ratio of now idle business channel machine more than a certain threshold value.If
More than this threshold value, step 201 is just performed, be not controlled the switching of channel device, time delay temporarily otherwise
Business is rejudged after T again whether busy, until it is determined that business is not busy, i.e. the ratio of idle business channel machine
When example is less than or equal to above-mentioned threshold value, the switching of channel device is just controlled.Wherein, time T is to be
System Preset Time.
Optionally, signaling under base station, indicates channel device to be controlled the trigger condition of the rotation of channel device
Can be specifically：Base station counts the run time of each Traffic Channel and control channel, when the current control of discovery
The run time of channel device is reached when being controlled the condition of channel device rotation the need for presetting, under the ability of base station
Signaling is controlled the rotation of channel device.
One Traffic Channel machine of free time have selected as to be switched according to the run time of channel device in base station
Traffic Channel machine after, the frequency of selected to be switched Traffic Channel machine is referred to as the first frequency, i.e.,
F2, the frequency of former control channel machine is the second frequency, i.e. F1.
202nd, the frequency of to be switched Traffic Channel machine is rewritten as the second frequency；
The frequency of the to be switched Traffic Channel machine that base station will be chosen is rewritten as control channel frequency F1 from F2.
203rd, the transmitting of to be switched Traffic Channel machine is opened, stops the transmitting of former control channel machine；
Using channel device synchronization principles in base station, the power amplifier (power amplification) of new control channel machine is opened,
To enter emission state, it is desirable to which selected Traffic Channel machine and former control channel machine is in the synchronous shape of frequency
State, closes the power amplifier of original control channel machine, stops the transmitting of former control channel machine.So, it is possible to make
New control channel machine enters working condition by original idle condition, makes original control channel machine by work
Enter idle condition as state.
204th, the frequency of former control channel machine is rewritten as the first frequency；
Afterwards, the frequency of former control channel machine is rewritten as F2 by base station, to cause that former control channel machine switches
It is Traffic Channel machine, former Traffic Channel machine switches to control channel machine.
Therefore, in sum, the embodiment of the present invention is the run time according to each channel device suitable to select
Traffic Channel machine switch to control channel machine, be capable of the service life of balanced each channel device, reduce control
Channel device processed is likely to occur the probability of failure.
