Specifically, Fig. 2 is the schematic flow sheet of the groundwork of LTE router in the prior art, in the application shown in Fig. 1
Under scene, as shown in Fig. 2 the workflow comprises the following steps：
Step 1, LTE router send uplink scheduling request by LTE modems (LTE Modem) to base station, on
State report containing LTE Modem hardware buffer queues in row dispatch request, for base station reference, and by base station issue including
The Downlink Control Information (Downlink Control Information, abbreviation DCI) of uplink scheduling authorization gives LTE router,
Bandwidth of air-interface is distributed for LTE router.
Step 2, LTE router receive the DCI for including uplink scheduling authorization by LTE Modem.
Step 3, LTE router are according to the speed of maximum bandwidth of air-interface, within each time cycle, according to priority from height to
Low order, it will be got from the data message of service layer different priorities queue in LTE Modem hardware buffer queues.
Wherein, LTE router can will need the different pieces of information message of up transmission in service layer, according to user configuration,
Different priority is assigned, such as high priority is assigned to real-time and important data message；Not strong to real-time is general
Logical data message, assigns low priority.Before the data message of different priorities is put into LTE Modem hardware buffer queue,
Cached first in the different priorities queue positioned at service layer, until drive software wherein data message will be taken away simultaneously
It is put into LTE Modem hardware buffer queue.
Fig. 3 is the schematic diagram that the data message of service layer is put into LTE Modem hardware buffer queues in the prior art.
As shown in figure 3, LTE router presses default period of time T, with the speed equal to maximum bandwidth of air-interface, according to priority from height
To low order, data message is taken from service layer by drive software, and the data message of acquirement is put into LTE Modem
Portion's hardware buffer queue.Such as the initial time in first period of time T 1, maximum bandwidth of air-interface speed are 7 data messages
Byte number, get 7 data messages are put into LTE Modem internal hardware buffering queues, wherein, data message 1 for height

According to the byte number of message；In the initial time of second period of time T 2, no matter the data in LTE Modem internal damping queues
Whether message is all sent to is eated dishes without rice or wine, and can all continue to take 7 data messages to be put into internal damping queue from service layer.Using
The scheme of message is taken by maximum bandwidth of air-interface, when service layer data message abundance, the data volume obtained every time is naturally larger than
Equal to currently practical bandwidth of eating dishes without rice or wine, because the queue of LTE Modem inner buffers can generally cache individual messages up to a hundred, when actual sky
When port band width is less than maximum bandwidth of air-interface, in cycle T 2,2 data messages can only be sent by eating dishes without rice or wine, but in service layer
7 data messages are taken out, the data message (even if priority is higher) that cycle T 2 takes from service layer will have taken before coming
To after hardware cache queue but the message (even if priority is low) that does not send also, as the data message 8 of high priority must be arranged
After the data message 4~7 of low priority, data message time delay after queuing will become very big.When bandwidth of air-interface deficiency
When situation persistently occurs, LTE Modem inner buffers queues will be packed with, and the data message of high priority is because can not be from operation layer
Face buffering queue is taken into hardware buffer queue and is dropped.
Step 4, LTE router are by the data message in LTE Modem internal hardware buffering queues according to hardware buffer team
Order in row, the bandwidth of air-interface distributed according to base station in uplink scheduling authorization, base station is sent to by eating dishes without rice or wine.
Due to the LTE Modem that current LTE router uses, hardware itself does not support service quality (Quality of
Service, abbreviation QOS), the data that inside has larger buffer area (such as 150000 bytes) to send service layer flow into
Row caching, when bandwidth of air-interface is insufficient and service layer has mass data message to be sent, as described in step 3, it can cause to have
After the lower-priority data message that the data message of high priority comes into buffering queue but do not sent before coming, due to
LTEModem is to be sent to the message sequence of hardware buffer queue to eat dishes without rice or wine so that the data message of high priority can not be sent out in time
Send, cause serious time delay and delay variation, Priority Inversion, or even when buffering queue is packed with, the data of high priority
Message is dropped because cannot be introduced into LTE Modem hardware buffer queues, can not be reached at all and be eated dishes without rice or wine to be transmitted, can not ensure
The QOS of business.
