Step S402, described high priority packet microwave data and described low-priority packet microwave data that demultiplexing is gone out carry out the decapsulation processing respectively;

Step S404 is respectively put into first transmission queue and second transmission queue with described high priority packet microwave data and described low-priority packet microwave data after the decapsulation processing;

Step S406 dispatches processing to the packet microwave data in described first transmission queue and described second transmission queue according to priority.

The present embodiment recipient is in the packet microwave data transmission course, by first transmission queue and second transmission queue packet microwave data of high priority and the packet microwave data of low priority are carried out the shunt transmission, the transmission needs of high-priority service have been guaranteed, compare the prior art scheme that message receives reorganization, it is easier that present embodiment is realized, configuration is simple, reduces system cost, and reliability improves.Simultaneously, present embodiment can adopt the Dynamic Bandwidth Allocation mode, and the transmission bandwidth of transmit leg packet microwave data is changed along with the change of network condition, further satisfies the demand of packet microwave data to real-time bandwidth.

In the specific implementation, time slot band width configuration indication information reusable transmits between transmit leg and recipient to the multiple connection frame that is used for transmitting packet microwave data.Fig. 5 is that the structure of an embodiment of multiple connection frame of the present invention is formed schematic diagram; As shown in Figure 5, the multiple connection frame of present embodiment comprises frame head, expense, fields such as dynamic bandwidth configuration indication information, data channel 1 and data channel 2.Wherein, frame head and expense are some fields that each frame must comprise, dynamic bandwidth configuration indication information is used to transmit the dynamic bandwidth configuration information, and data channel 1 and data channel 2 are respectively applied for and send high priority packet microwave data and low-priority packet microwave data.Wherein, described dynamic bandwidth configuration indication information comprises that dynamic bandwidth configuration sign, link send indication, the indication of dynamic bandwidth information and frame and transmit four fields such as time slot data.In the specific implementation, dynamic bandwidth configuration indication information can account for 16bits in the multiple connection frame, and wherein dynamic bandwidth configuration sign accounts for 4bits, and link sends indication and accounts for 2bits, and the indication of dynamic bandwidth information accounts for 2bits, and frame transmits the time slot data and accounts for 8bits.

The implication of each field is resolved as follows:

1) dynamic bandwidth configuration sign: normal in service when not needing to adjust transmission bandwidth, dynamic bandwidth configuration sign=0110 in the multiple connection frame that transmit leg sends, expression present frame do not have dynamic bandwidth configuration indication information to send; And when needs send dynamic bandwidth configuration indication information, dynamic bandwidth configuration sign=1001 in the multiple connection frame that transmit leg sends; Receive the receiving terminal that is of dynamic bandwidth configuration sign=1001, at this moment need the dynamic bandwidth configuration indication information that receives is fed back, in the dynamic bandwidth configuration indication information of receiving terminal feedback dynamic bandwidth configuration sign=1001 is set.

2) link sends indication: the 01=transmit leg sends dynamic bandwidth configuration indication information; 10=recipient feeds back receiving dynamic bandwidth configuration indication information.

3) dynamic bandwidth information indication: the dynamic bandwidth configuration indication information of 00=present frame is not an ending segment; The dynamic bandwidth configuration indication information of 01=present frame is an ending segment.The dynamic bandwidth configuration indication information of present frame is not that ending segment is meant that two frames are just finished the transmission of indication information after transmitting and finishing when adopting two continuous frames to transmit dynamic bandwidth configuration indication information, can realize the time slot bandwidth counting of 16bit like this.

4) frame transmits the time slot data: the shared timeslot number of corresponding high priority packet microwave data in the indication transport layer multiple connection frame, when adopting two frame phase add modes, can realize the transmission of 16bits time slot counting.And the time slot bandwidth number of low-priority packet microwave data can pass through, and the formula of low priority time slot bandwidth=always transmit time slot bandwidth-high priority time slot bandwidth calculates gained.

How illustrate dynamic bandwidth configuration indication information with asymmetric manner below transmits between transmit leg and recipient.

Under the normal condition, dynamic bandwidth configuration sign=0110, dynamic bandwidth configuration indication information=0110000000000000; When transmit leg is adjusted according to the initiation dynamic bandwidth, the employing two continuous frames sends, in this two frame, dynamic bandwidth configuration sign=1001, first frame dynamic bandwidth configuration indication information=10010100xxxxxxxx, and then the second frame dynamic bandwidth disposes indication information=10010101xxxxxxxx, the 3rd frame dynamic bandwidth configuration sign reverts to 0110 again, and dynamic bandwidth configuration indication information=0110000000000000 is multiplexed into high priority packet microwave data and low-priority packet microwave data in the transmission multiple connection frame according to adjusted crack band width configuration at the 3rd frame transmit leg simultaneously.

After the recipient receives dynamic bandwidth configuration indication information, adjust local terminal time slot bandwidth at dynamic bandwidth configuration indication information that will receive and also the time slot configuration data that receives is fed back to transmitting terminal simultaneously, recipient's feedback also is to send two frames continuously, dynamic bandwidth configuration sign=1001 in this two frame; Receive dynamic bandwidth configuration indication information=10011000xxxxxxxx in first frame that feeds back behind first frame, and then receive dynamic bandwidth configuration indication information=10011001xxxxxxxx in second frame that feeds back behind second frame, revert to again at the 3rd frame recipient's dynamic bandwidth configuration sign=0110, and dynamic bandwidth configuration indication information=0110000000000000 goes out high priority and low-priority packet microwave data the 3rd frame recipient according to adjusted time slot band width configuration demultiplexing from transmit the multiple connection frame simultaneously.

Transmit leg compares with the time slot band data that sends after receiving the dynamic bandwidth configuration indication information of recipient's feedback, represents then that as unanimity transmission is consistent with reception two ends time slot configuration information, and system works is normal; If inconsistent then show the time slot configuration information inconsistency that sends and receive two ends, system works is undesired, needs transmit leg to send dynamic bandwidth configuration indication information to the recipient again according to current transmission bandwidth.

Need carry out time slot continuously when adjusting when transmit leg detects the time slot configuration information inconsistency that sends and receive two ends, behind the transmit frame of two dynamic bandwidths configuration signs=0110, send new adjustment time slot bandwidth once more at least at interval.
