Beneficial effect to reaching is set forth in.
As shown in Fig. 2 for issuing control method for signaling frames schematic flow sheet in the embodiment of the present invention, its concrete handling process
It is as follows：
Step 21, replaces the signaling that speech frame is issued in the BS monitoring stipulated time length in group system in business state
The quantity of frame；
When trunked call enters business state, the BS in group system is also at business state.
In the embodiment of the present invention, the BS in group system in business state can be to replacing under speech frame in stipulated time length
The quantity of the signaling frame sent out enters Mobile state monitoring, and BS pre-sets each time point of monitoring and stipulated time length, can with but not
It is limited to for stipulated time length to be set to 1 second.
Wherein, the quantity for replacing the signaling frame that speech frame is issued in BS monitoring stipulated time length can be, but not limited to include
Following two kinds of embodiments：
The first embodiment, BS is for current point in time as end time point, and length is that the stipulated time is long
The time period of degree, the quantity for replacing the signaling frame that speech frame is issued in the time period is obtained, by the quantity of the signaling frame for obtaining, really
It is set in stipulated time length and replaces the quantity of the signaling frame that speech frame is issued, for example, it is stipulated that time span is 1 second, and BS is arrived
During up to default time point of monitoring, quantity n of signaling frame that speech frame issue is replaced before monitoring current point in time in 1 second；
Second embodiment, BS is for current point in time as end time point, and length is that defined amount is described
The time period of stipulated time length, obtain the quantity for replacing the signaling frame that speech frame is issued in the time period, the signaling that will be obtained
The quantity of frame and the ratio of the defined amount, are defined as in stipulated time length replacing the number of the signaling frame that speech frame is issued
Amount, for example, it is stipulated that time span is 1 second, the defined amount is T, and, when default time point of monitoring is reached, monitoring is current for BS
The ratio N/T of quantity N with defined amount T of the signaling frame that speech frame is issued is replaced before time point in the T seconds.
Step 22, if the quantity of the signaling frame for monitoring is not less than default defined threshold, judges next forward frame
Whether it is the signaling frame for needing to replace that speech frame is issued；
Whether BS judges the quantity of the signaling frame for monitoring less than default defined threshold, if judging the signaling for monitoring
The quantity of frame is less than default defined threshold, then it is assumed that the signaling frame that now need not be issued to replacing speech frame carries out issuing control
System, if judging, the quantity of the signaling frame for monitoring is not less than default defined threshold, then it is assumed that now need to replacing voice
The signaling frame of frame carries out issuing control, and BS judges whether next forward frame is the signaling frame for needing to replace that speech frame is issued, if
The forward frame is signaling frame, has now reached the end time point and now F-FCH of the corresponding holding time section of the signaling frame
In only full rate speech frame, then BS confirm that the forward frame is the signaling frame for needing to replace that speech frame is issued.
In the embodiment of the present invention, the default defined threshold is configured according to actual voice prescription by BS.
Step 23, when judging that next forward frame is the signaling frame for needing replacement speech frame to issue, abandons the signaling
Frame.
The embodiment of the present invention is proposed, if BS judges that next forward frame is the signaling frame for needing to replace that speech frame is issued,
Then BS can directly abandon the signaling frame, so as to the quantity for replacing the signaling frame that speech frame is issued is controlled in certain scope
It is interior, it is to avoid excessive speech frame is replaced.
Additionally, BS can selectively abandon signaling frame with the priority that issues according to signaling frame, specifically：BS is judging
When to go out next forward frame be to need to replace signaling frame that speech frame is issued, obtain that the signaling frame is corresponding to issue priority value,
Then priority value is issued according to what is obtained, judge that the signaling frame is corresponding and issue whether priority is issued preferentially less than default
Level, if judging, the corresponding priority that issues of the signaling frame issues priority less than default, then it is assumed that the signaling frame is not weight
The signaling frame wanted, therefore the signaling frame is abandoned, if judging, the corresponding priority that issues of the signaling frame is not less than default issuing
Priority, then it is assumed that the signaling frame is important signaling frame, therefore does not do discard processing to the signaling frame, according to normal process stream
Journey issues the signaling frame, so as to ensure that normally issuing for important signaling frame.
In the embodiment of the present invention, can by PDS previously according to the corresponding business of signaling frame type of service arranging signaling
Frame issues priority value, for example, if according to the type of service of the corresponding business of signaling frame, PDS determines that the business is important industry
Business, then arrange higher issuing priority be corresponding for the signaling frame and issue priority value, if PDS is according to the corresponding industry of signaling frame
The type of service of business determines the business for inessential business, then for the signaling frame arrange it is relatively low issue priority it is corresponding under
Priority value is sent out, the priority value carrying that issues for arranging is sent to BS in the specific field of signaling frame by PDS, and BS receives letter
After making frame, that extracts the signaling frame from the specific field of the signaling frame issues priority value；
Priority value is issued in addition it is also possible to voluntarily be determined after signaling frame is received by BS, specially：BS is prestored
Type of service and issue the corresponding relation between priority value, it needs to be determined that when issuing priority of certain signaling frame, first really
The type of service of the business corresponding to the fixed signaling frame, then according to the type of service determined, in above-mentioned type of service with
Send out in the corresponding relation between priority value, that searches the signaling frame issues priority value.
In the embodiment of the present invention, issuing priority can improve with the increase for issuing priority value, that is, issue preferential
Level value is bigger, and it is higher to issue priority, for example, signaling frame 1 issues priority value for 1, and signaling frame 2 issues priority value
For 2, then the priority that issues of signaling frame 2 issues priority higher than signaling frame 1；Issuing priority can also be preferential with issuing
The increase of level value and reduce, that is, it is bigger to issue priority value, it is lower to issue priority, and for example, signaling frame 1 issues priority
It is worth for 1, signaling frame 2 issues priority value for 2, then the priority that issues of signaling frame 1 issues priority higher than signaling frame 2.
From above-mentioned processing procedure, in embodiment of the present invention technical scheme, the BS in group system in business state is supervised
Regulatory control is fixed time and replaces the quantity of the signaling frame that speech frame is issued in length, if the quantity of the signaling frame for monitoring is excessive, recognizes
For needing the signaling frame issued to replacing speech frame to carry out issuing control, if next forward frame is to need replacement speech frame to issue
Signaling frame, then BS abandon the signaling frame, control in certain scope so as to the quantity of signaling frame that speech frame issues will be replaced
It is interior, it is to avoid excessive speech frame is replaced, therefore it is effectively improved the speech quality of trunked call.
