The most important feature of radio-frequency nodes 20 is to complete the transmitting-receiving of less radio-frequency function, and L1 or L1+L2 or the L1+L2+L3 function etc. of radio function in addition also may be implemented, its superior node 10 completes the other parts of radio function.For example, superior node 10 completes L2+L3 function if radio-frequency nodes 20 only complete L1 function.In addition, superior node 10 is completed at the same time the control function of radio-frequency nodes 20.Radio-frequency nodes 20 and its superior node 10 form one end of wireless communication system, carry out wireless communication with the wireless transceiver 30 of the other end.
It should be noted that the embodiment of the present invention is not construed as limiting the specific form of superior node 10, radio-frequency nodes 20 and wireless transceiver 30.For example, superior node 10 can be BBU, radio-frequency nodes 20 can be RRU, and wireless transceiver 30 can be terminal or transfer base station etc..
As depicted in figs. 1 and 2, transport layer 50 is carried out by Transmission system 40 between radio-frequency nodes 20 and superior node 10 to communicate.
Here, Transmission system is referred to as transmission network, and the embodiment of the present invention is not especially limited transmission network, for example, transmission network can for time division multiplexing (Time Division Multiplexing,

Fig. 3 is the flow chart of the method for the data transmission of one embodiment of the invention.Method shown in Fig. 3 includes:
S301 determines the transmission quality between radio-frequency nodes and superior node.
S302 adjusts the transmission rate of the wireless traffic carried between the radio-frequency nodes and the superior node according to the transmission quality.
In the embodiment of the present invention, according to the transmission quality between superior node and radio-frequency nodes, the transmission rate of wireless traffic is adjusted.In this way, the service feature of radio layer can not only be promoted, but also it can reduce transmission cost.
In the embodiment of the present invention, method shown in Fig. 3 is mainly executed by superior node.Wherein, in S301, it can be and monitor the transmission quality by radio-frequency nodes and inform superior node.That is, S301, which can be superior node, obtains the transmission quality obtained by radio-frequency nodes from radio-frequency nodes.
Specifically, S301 may include: the transmission information according to the Transmission system between radio-frequency nodes and superior node, determine the transport quality parameters.Wherein, the transport quality parameters may include at least one of the following: packet loss, the bit error rate, shake and time delay.That is, the assessment for transmission quality can be assessed according to one or more indexs in packet loss, the bit error rate, shake and time delay.
Here, transport quality parameters also may include other configured transmissions, be not construed as limiting here.For example, transport quality parameters may include transmission available bandwidth etc..The evaluation criteria of transport quality parameters can be default
The fixed value set, is also possible to the parameter value measured by the previous moment at current time, is not construed as limiting here.
In this way, can determine the variation of transmission quality according to the variation of transport quality parameters.
It is understood that when detect packet loss increase, the bit error rate increase, shake increase, time delay increase in it is one or more when, can determine transmission quality decline.When detect packet loss reduce, the bit error rate reduce, shake reduce, time delay reduce in it is one or more when, can determine transmission quality rise.
Further, in S302, when transmission quality rises, the transmission rate of the wireless traffic is promoted；Or by promoting wireless-modulated order to promote the transmission rate of the wireless traffic.When transmission quality decline, the transmission rate of the wireless traffic is reduced；Or by reducing wireless-modulated order to promote the transmission rate of the wireless traffic.
Optionally, if wireless traffic divides priority, it is also based on transmission quality in S302, flow control is carried out to the business of low priority.
As an example it is assumed that the second wireless traffic that wireless traffic includes the first wireless traffic that priority is 1 and priority is 2, the i.e. priority of the first wireless traffic are higher than the second wireless traffic.So when transmission quality declines, the transmission rate of the second wireless traffic can be reduced in order to preferentially guarantee the transmission of the first wireless traffic.For example, the transmission rate of the second wireless traffic can be reduced by 50%.
As it can be seen that transmission rate of the present embodiment by adjusting wireless traffic, is able to ascend the professional ability of radio layer.Using method shown in the present embodiment, the quality requirement for transmission network can be reduced, and then reduces transmission cost, and promote the technical feasibility of transmission in turn.
Optionally, as one embodiment, base station can provide multiple cells, i.e. radio-frequency nodes 20 can access multiple cells simultaneously.As shown in figure 4, including the first radio-frequency nodes 21 and the second radio-frequency nodes 22 in Fig. 4.In the embodiment shown in fig. 4, radio-frequency nodes (the first radio-frequency nodes 21 or the second radio-frequency nodes 22) be can be while accessing first community 61 and second community 62.It is also possible to the first radio-frequency nodes 21 access first community 61, the second radio-frequency nodes 22 access second community 62.
At this point, wireless transceiver 30 is linked into wireless system by multiple cells (first community 61 and second community 62 in such as Fig. 4).Wherein, wireless transceiver 30 can carry out sending and receiving data by multiple cells simultaneously.For example, each cell can correspond to a data stream.
Under the scene of similar Fig. 4, Transmission system 40 can carry the information of cell.So, it is appreciated that transmission quality relevant to cell can be determined in S301, and then in S302 adjust respective cell wireless traffic transmission rate.Wherein, the transmission rate of the wireless traffic of respective cell can be understood as the transmission rate of the data flow of respective cell.
By taking first community as an example, transmission quality relevant to first community can be determined according to the transport quality parameters of the Transmission system between radio-frequency nodes and superior node.And according to transmission quality relevant to first community, the transmission rate of the wireless traffic relevant with first community carried between the radio-frequency nodes and the superior node is adjusted.That is, the transmission rate of adjustment data flow corresponding with first community.
Wherein, if detect one or more during corresponding with first community packet loss increases in Transmission system, the bit error rate increases, shake increases, time delay increases, it can determine transmission quality decline relevant to first community.If detect one or more during corresponding with first community packet loss reduces in Transmission system, the bit error rate reduces, shake reduces, time delay reduces, it can determine that transmission quality relevant to first community rises.
Wherein it is possible to adjust the transmission rate of wireless traffic by adjusting wireless-modulated order.For example, promoting the transmission rate of wireless traffic relevant to first community, or promote the transmission rate of wireless traffic relevant to first community by promoting wireless-modulated order when transmission quality relevant to first community rises.For example, reducing the transmission rate of wireless traffic relevant to first community, or reduce the transmission rate of wireless traffic relevant to first community by reducing wireless-modulated order when transmission quality relevant to first community decline.
As it can be seen that transmission rate of the present embodiment by adjusting the wireless traffic of respective cell, is able to ascend the professional ability of the radio layer of respective cell.Using method shown in the present embodiment, the quality requirement for transmission network can be reduced, and then reduces transmission cost, and promote the technical feasibility of transmission in turn.
Optionally, transmission quality relevant to multiple cells can be determined in S301, and the data volume between multiple cells is further being adjusted in S302 to adjust the transmission rate of wireless traffic.
For example, transmission quality relevant to first community and transmission quality relevant with second community can be determined according to the transport quality parameters of the Transmission system between radio-frequency nodes and superior node.When transmission quality relevant to second community is better than transmission quality relevant with first community, the data of first community are switched into second community and are transmitted.
It should be noted that the relevant transmission quality of cell can be determined by superior node here；Alternatively, the relevant transmission quality of cell can also be monitored by radio-frequency nodes, and the transmission quality monitored is informed into superior node with the mark of corresponding cell by radio-frequency nodes.
For example, script can be switched to second community in the higher data of priority that first community is transmitted, to ensure the transmission rate of the higher data of the priority.It is understood that higher priority can be arranged for important data in controller or administrator.
It is understood that being transmitted here by the way that the data of first community are switched to second community, to reach
It reduces the transmission rate in first community and promotes the purpose of the transmission rate in second community.
At the same time it can also including: that the high data of the subsequent priority that will be transmitted are assigned to the second community to transmit.It is transmitted for example, the high data of the priority that will be transmitted in the original plan by first community are assigned to second community by superior node, to ensure the transmission rate of the high data of the priority.
That is, the high significant data of priority when distributing data, can be assigned to the good cell of transmission quality by superior node.
After subsequent transmission quality relevant to first community improves again, the data for switching to second community can also be switched back again.
In the embodiment of the present invention, the wireless traffic in S302 can be the wireless traffic of wireless traffic bottom or the wireless traffic of wireless traffic high level, as shown in Figure 1.Or the wireless traffic in S302 is also possible to the wireless traffic of wireless traffic layer, as shown in Figure 2.
As it can be seen that transmission rate of the present embodiment by adjusting wireless traffic, is able to ascend the professional ability of radio layer.Using method shown in the present embodiment, the quality requirement for transmission network can be reduced, and then reduces transmission cost, and promote the technical feasibility of transmission in turn.
It should be noted that the method for the embodiment of the present invention is also possible to the radio layer compress technique based on transmission quality.Or it also can be applied to transport layer, such as compression and multiplexing technology based on transmission quality.This is not limited by the present invention.
