In digital cluster communication (English：DMR, referred to as：Digital Mobile Radio) intercom field, in order to be promoted The utilization rate of trunk desk channel and solve a large amount of intercoms simultaneously using channel when issuable channel confliction, propose at present A kind of communication system including multiple trunk desks, as shown in Figure 1.In the communication system, need to mark each time slot only Identity (English：Identification, referred to as：ID) number, it is ensured that can be by ID come when identifying specific in channel management Gap channel.Equally, in each intercom, can all there be the corresponding specific physical channel relation mapping table of a time slot ID number, This correspondence will be consistent with the correspondence of base station.

Two non-slotted channels of each trunk desk can be used in the communication system, so, whole system needs pair Each non-slotted channel is managed, which non-slotted channel is communicating, which non-slotted channel is in idle condition, which non-slotted channel First used.A home channel can be set up in order to be managed collectively, in communication system, all intercoms can all be switched to this Under a home channel, when intercom initiates voice or when short message service, home channel again can switching at runtime to other free time when On gap channel, this process, which is exactly this programme, to be described in detail.

Therefore a kind of method of channel management of proposition of the embodiment of the present invention and device, letter is waited for for simply and effectively managing Road, such as when home channel is occupied by business, which idle non-slotted channel conduct how system fast and effectively to determine New home channel.The management method of home channel includes that the channel after system electrification initialization determines, service communication process In home channel updating maintenance and the lookup again of the home channel after networking again.

The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

Communication system is not aware that in the communication system there is several trunk desks after power-up, for each trunk desk, keeps Wait whether channel has been determined in the communication system.Based on this, the embodiment of the present invention provides a kind of method of channel management, ginseng It reads shown in Fig. 2, the method can be used for communication system initial power-on, or the scene for having new trunk desk that communication system is added In, the method can specifically include as follows：

S201, the first trunk desk send channel frame to N number of second trunk desk, and receive N number of second trunk desk and send Channel frame.

Wherein, the N is the integer more than 0；The channel frame, which carries, sends the use that the trunk desk of the channel frame is recorded In the channel letter for identifying each non-slotted channel of the sequence number and trunk desk of current home channel in the communication system Breath.First trunk desk is any trunk desk in the communication system, and second trunk desk is in the communication system Other trunk desks in addition to first trunk desk.

S202, the sequence that first trunk desk is recorded according to the sequence number and N number of second trunk desk of self record Each time slot letter in the channel information of each non-slotted channel and N number of second trunk desk in row number, first trunk desk The channel information in road determines current home channel.

Wherein, the sequence number can be the corresponding ID number of non-slotted channel.

Communication system is when initializing networking, and after power-up, each trunk desk can send channel frame to other trunk desks, The channel frame can be as shown in table 1.

Table 1

Wherein, SlotId and Prior is every trunk desk fixed setting, and the home channel ID that RestChan is system Value, RestChan fields indicate that the home channel of record is sky with " 0 ".ChanBusy and RestChanBusy fields can be used " 0 " indicates channel idle, indicates that channel is busy with " 1 ", other fields are the information of sender's trunk desk.

For example, when trunk desk 1 record home channel information be sky, and the priority of trunk desk 1 be 3 when, trunk desk 1 send out The channel frame sent is as shown in table 2.

Table 2

When communication system initialization networking, if there was only a trunk desk in the communication system, which is sending letter Will appear time-out after road, (channel frame that trunk desk is not received by the transmission of other trunk desks within a preset period of time is determined as Time-out), after 3 times are attempted, in the case of can not still obtaining home channel, it can confirm the time slot of the ID number minimum of this trunk desk Channel is as home channel.If receiving the channel frame of other trunk desks transmission in preset time, and letter is waited in frame Road information is 0, needs to compare the ID number of the priority and corresponding non-slotted channel of each trunk desk, and priority is high and ID number Small non-slotted channel is determined as home channel.If the home channel information carried in the channel frame received is non-zero, show have Home channel, update preserve this information.

The process of communication system initialization networking specifically may refer to shown in Fig. 3：

S301, trunk desk send channel frame to other trunk desks respectively.

S302, the trunk desk determine whether time-out；If so, executing step S303；If it is not, executing step S306.

Specifically, whether the trunk desk does not receive the channel frame of other trunk desks transmission in preset time period, it is determined that be Time-out.

S303, the trunk desk determine in communication system whether existing home channel；If so, executing step S304；If it is not, Execute step S305.

Wherein, the home channel information of trunk desk record is not sky, alternatively, being taken in the channel frame that other trunk desks are sent When the home channel information of band is not empty, existing home channel in communication system is determined.

S304, the trunk desk determine home channel based on the priority of each trunk desk and the ID number of non-slotted channel.

Specifically, in the sequence number of first trunk desk record and the sequence number of N number of second trunk desk record When being sky, first trunk desk determines that channel status is sky in first trunk desk and N number of second trunk desk Not busy non-slotted channel.First trunk desk determines the time slot of highest priority in the non-slotted channel that the channel status is idle Channel.First trunk desk determines that the non-slotted channel of sequence number minimum in the non-slotted channel of the highest priority is currently to keep Wait channel.Wherein, the priority of non-slotted channel can use a digital representation, and number is bigger, and expression priority is higher, alternatively, number The smaller expression priority of word is higher, and the embodiment of the present invention is not specifically limited herein.

S305, the home channel information of the trunk desk more new record.

Specifically, the trunk desk record home channel information be sky, and other trunk desks record wait for letter When road information is sky, the trunk desk determines that the non-slotted channel corresponding to the home channel ID number of self record is currently to wait for Channel.

It is sky in the home channel information of trunk desk record, and the home channel information of other trunk desks record is not When empty, the trunk desk determines highest priority in the non-slotted channel corresponding to the home channel ID number of other trunk desks record Non-slotted channel；The trunk desk determines that the non-slotted channel of sequence number minimum in the non-slotted channel of the highest priority is currently to keep Wait channel.

It is not sky in the home channel information of trunk desk record, and the home channel information of other trunk desks record is not For sky when, the trunk desk determine self record home channel ID number and other trunk desks record home channel ID number institute The non-slotted channel of highest priority in corresponding non-slotted channel；The trunk desk determines in the non-slotted channel of the highest priority The non-slotted channel of ID number minimum is current home channel.

S306, trunk desk determine whether the number of time-out is more than preset value；If so, executing step S307；If it is not, executing step Rapid S301.

Wherein, preset value can be 3, can be other values, and the embodiment of the present invention is not specifically limited herein.

The non-slotted channel of the ID number minimum of itself is determined as home channel by S307, the trunk desk 1.

After communication system initialization is completed, home channel can determine whether.When subsequently having service communication, communication system Just it needs to be determined which non-slotted channel is new home channel, during this lookup, due to inquiring other trunk desks Free timeslot channel needs to carry out communications access by the internets IP, and there are certain delays for IP interconnections access, while also having There may be the delays that access conflict generates, and communication system is needed from the business that receives to the new home channel of determination more than ten It is completed in millisecond, the otherwise operation of system will appear exception.Based on this, a kind of method of channel management provided in an embodiment of the present invention Flow chart, as shown in fig.4, this method can be used for the updating maintenance of the home channel of communication system during service communication Scene in, the method can specifically include as follows：

S401, when current home channel is occupied, the first trunk desk where the current home channel redefines New home channel.

S402, first trunk desk send channel frame to N number of second trunk desk；The channel frame carries described new keep Wait the corresponding sequence number of channel.

Wherein, the new home channel is determined by following any mode：

Optionally, first trunk desk determines the new home channel according to channel management table, including：

When first trunk desk determines that channel status in the communication system is idle according to the channel management table Gap channel；First trunk desk determines the non-slotted channel of highest priority in the non-slotted channel that the channel status is idle； First trunk desk determines that the non-slotted channel of sequence number minimum in the non-slotted channel of the highest priority is described new keeps Wait channel.

Optionally, first trunk desk can also receive the channel frame of any one second trunk desk transmission；Described The channel of each non-slotted channel in any one described second trunk desk is carried in the channel frame that one the second trunk desk of meaning is sent State；First trunk desk updates the channel management table based on the channel frame that any one described second trunk desk is sent.

When subsequently having service communication, communication system can follow a principle in the new home channel of determination：First It is searched in the trunk desk where home channel, if the non-slotted channel that the trunk desk is not idle, is looked into other trunk desks It looks for.

When home channel receives business, system can judge whether another time slot of the same trunk desk is idle, If idle, home channel is switched to another described non-slotted channel；Otherwise, system will search the free time in other trunk desks Time slot is as new home channel.The inquiry of other trunk desk free timeslot channels just needs by the internets IP communicate Access, IP interconnections access that there are certain delays, while being also possible to there are the delay that access conflict generates, and communication system from It receives business to need to complete in more than ten milliseconds to determining new home channel, the otherwise operation of system will appear exception.Institute With for the lookup of other trunk desk free timeslot channels, the embodiment of the present invention is proposed is waited for by the determination of channel management table The processing method of channel.This method is specific as follows：
