Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the forward direction transmitting terminal is BBU, and receiving terminal is RRU; As shown in Figure 2, oppositely transmitting terminal is RRU, and receiving terminal is BBU.
As shown in Figure 3, oppositely, only be not divided into transmitting terminal and receiving terminal before wherein not distinguishing.Among Fig. 3 at transmitting terminal, the transmitting terminal O point of top signaling (the O point here can not be estimated to the instantaneous delivery of P point signaling), the O point determines whether to write a frame or multiframe signaling downwards according to the blocked state of next node P.At receiving terminal S point, take out the signaling (instantaneous delivery equally at this time can not be estimated) of a frame or multiframe from R point signaling Buffer Pool 3.Yet adopt certain specific protocol to transmit signaling usually between node Q and node R, the flow of signaling is fixed between these 2.Yet between the transmitting terminal O of signaling point and P point, flow can not be estimated moment between receiving terminal R point and S point, because QR adopts a certain protocol, and can not determine between the OP, in the O point signaling that the sends transmission of to burst, may be far longer than the flow between node Q and the R.When signaling happens suddenly big flow, if there is not suitable flow control methods, be easy to cause losing in a large number of signaling, make BBU and RRU Control on Communication interrupt the RRU system in case of system halt.
Main design of the present invention is: baseband subsystems and Radio Frequency Subsystem carry out signaling when transmission, by at transmitting terminal and receiving terminal one or more data buffer zones being set respectively the signaling of transmission are carried out flow control.
As shown in Figure 4, the device of a kind of signaling traffic control comprises transmitting terminal and receiving terminal, and receiving terminal and transmitting terminal (as BBU and RRU, perhaps RRU and BBU) carry out being connected physically by light mouth or electricity mouth, wherein,
Transmitting terminal comprises top signaling transmitting element, the first signaling buffer cell, coding unit, the second signaling buffer cell and transmitting terminal interface protocol unit.
The top signaling transmitting element is used for writing signaling to the first signaling buffer cell, and judges whether the first signaling buffer cell blocks, if, then stop to write signaling to the first signaling buffer cell, otherwise, write signaling to the first signaling buffer cell;
The mode that the top signaling transmitting element adopts inquiry or interrupts, judge whether the first signaling buffer cell can also receive a complete frame or multiframe signaling, if blocking, the first signaling buffer cell can also not receive signaling, be that unit writes signaling to the first signaling buffer cell with the frame then, when the first signaling buffer cell blocks, stop to write signaling by the top signaling transmitting element.The moment flow that wherein writes signaling can be far longer than the signaling traffic of base band radio frequency interface agreement regulation.
The first signaling buffer cell is used to receive the signaling that the top signaling transmitting element writes, if the second signaling buffer cell blocks, the data that then stop to receive send to coding unit, otherwise, send the data that receive to coding unit;
The egress rate of first signaling buffer cell transmission data is roughly suitable with the signaling traffic speed of base band radio frequency interface agreement regulation.If the second signaling buffer cell does not block, then the first signaling buffer cell is that unit of transfer sends data to coding unit with the frame.Because the data of each frame are through behind the coding unit, all can increase the byte number of this frame, so when the first signaling buffer cell sends data, between every frame, add certain time interval T, need to stop a period of time after promptly sending a frame downwards, send second frame again.If the second signaling buffer cell blocks, then the first signaling buffer cell should continue to send present frame, after the present frame transmission is finished, stops to send next frame, continues to send data to coding unit after the second signaling buffer cell unblocking.
The first signaling buffer cell is a unit buffering signaling with a frame.Because the interface of this moment is the top signaling transmitting element, so signaling all is to transmit with the form of a frame one frame at the upper layer software (applications) interface.

Decoding unit is corresponding with the coding unit of transmitting terminal, coded system and the escape mode used according to coding unit, and can obtain needed is the signaling of unit with the frame.
Through decoding unit to signaling decoding after, the speed of signaling is less than the signaling traffic in the interface protocol.
The 3rd signaling buffer cell is used to receive the decoded described signaling of process that decoding unit writes, and described signaling is sent to the top signaling receiving element;
To the 3rd signaling buffer cell, inlet rate is smaller, and egress rate is bigger.The 3rd signaling buffer cell is to be unit buffering signaling with a frame.
