Definitions
- Interface reverse congestion control method device and transceiver base station of base station controller and base transceiver station
- the present invention relates to the field of network communication technologies, and in particular, to an interface reverse congestion control method, apparatus, and transceiver base station for a base station controller and a base transceiver station.
- the air interface rate is generally the bottleneck of communication. Therefore, the air interface rate is the focus of congestion control and bandwidth optimization.
- the reverse data flow direction is: AT (Access terminal) -> BTS (Base Transceiver Station) -> BSC (Base Station Controller, base station) Controller) -> PCF (Data Service Control Function Module) -> Core Network. Since the single-user air interface reverse peak rate can reach 1.8Mbps, the interface bandwidth between ABIS (BTS ⁇ BS ⁇ may become the bottleneck of communication).
- the BTS receives the data transmitted by the AT through the air interface, and puts the data into the corresponding queue according to the priority of the data. Then, the BTS reads the data from the queue according to a certain scheduling algorithm, and uses the ABIS interface to It is sent to the BSC.
- the buffer length the amount of data stored in the buffer at a time f.
- the queue length should be smaller than the buffer length.
- the queue length of the BTS queues with lower priority traffic flows increases.
- the BTS has to discard the received data. If the instantaneous air interface rate exceeds the bandwidth of the ABIS interface, it will not cause the BTS queue to overflow. However, when the air interface rate continues to exceed the bandwidth of the ABIS interface for a long time, the BTS queue may overflow.
- the bandwidth of the ABIS interface is insufficient or the bandwidth is insufficient in a short time, which causes the reverse traffic congestion of the ABIS interface. At this time, if the appropriate control is not performed, the BTS buffer overflows, resulting in data loss.
- TCP Transmission Control Protocol
- Method 1 TCP will start the slow start algorithm and the congestion avoidance algorithm because of the packet loss of the BTS, thereby alleviating the reverse traffic congestion of the ABIS interface.
- the BTS discards the data packet and causes the timeout to retransmit, and the slow start and congestion avoidance algorithm is started.
- the data discarded by the BTS causes the RLP (Radio Link Protocol) to retransmit, and the retransmitted data is not only wasted.
- the air interface resources also increase the congestion pressure of the ABIS interface, and slow start and congestion avoidance seriously affect the system throughput.
- Method 2 After the ABIS interface is congested, the BTS sends a broadcast message to notify all ATs of the maximum transmission rate allowed by the system, thereby controlling the transmission rate of all ATs, limiting the air interface reverse rate, and slowing down and further eliminating congestion on the ABIS interface; After the congestion condition of the ABIS interface is removed, the BTS sends a broadcast message to restore the maximum transmission rate of all ATs.
- the BTS discards the data packet, which also causes timeout retransmission.
- the retransmitted data wastes the air interface resources and increases the congestion pressure of the ABIS interface.
- Congestion will continue during the delay period.
- the maximum transmission rate of all ATs is limited, or the BTS discards all received data packets after congestion, and cannot provide a differentiated service ambiguity for users with higher priority.
- all the ATs will reduce the transmission rate at the same time. After the congestion is removed, all the ATs will increase the transmission rate at the same time, which may cause the BTS to frequently start and stop the congestion control process, thus causing the system to oscillate.
- the discarding of the data packet is not fed back to the transmitting end, so that the congestion of the ABIS interface cannot be alleviated and avoided.
- the data discarded by the BTS does not cause data retransmission, resulting in data loss.
- VOIP Voice Over IP
- VT Video Telephone, video telephony
- continuous speech frames or video frames are discarded. It will seriously reduce the quality of service and affect the user experience.
- the upper layer transport protocol cannot avoid the phenomenon that BTS drops packets.
- air interface resources are relatively scarce resources. BTS will receive The data that is sent is discarded, and the air interface resources are wasted. That is to say, when the transmit power of the AT is not reduced, that is, the reverse interference is not reduced, the actual throughput of the system is decreased, thereby reducing the utilization of the air interface resources.
- the embodiment of the present invention mainly provides an interface reverse congestion control method, a device, and a transceiver base station of a base station controller and a base transceiver station.
- Congestion control processing is performed on the interface of the base station controller and the receiving and receiving base station in reverse, effectively avoiding data loss
- the utilization of air interface resources is improved and user satisfaction is improved.
- the method for the reverse congestion control of the base station controller and the base transceiver station includes:
- congestion control processing is performed on the interface between the base station controller and the base transceiver station.
- the present invention further provides an interface reverse congestion control apparatus for a base station controller and a base transceiver station, wherein the device is provided with a storage module, a detection module, and a congestion control processing module, and the congestion control processing module is respectively connected to the storage module and the detection module;
- the storage module stores an interface reverse pre-congestion control threshold of the base station controller and the base transceiver station;
- the detecting module detects the reverse congestion degree of the interface between the base station controller and the transmitting and receiving base station, and outputs the detection result; the congestion control processing module: determines the reverse congestion degree of the interface between the base station controller and the transmitting and receiving base station outputted by the detecting module to reach the storage module When the pre-congestion control threshold is used, congestion control processing is performed on the interface between the base station controller and the base transceiver station.
- the present invention further provides a transceiver base station, wherein the transceiver base station is provided with a storage module, a detection module, and a congestion control processing module, and the congestion control processing module is respectively connected to the storage module and the detection module;
- the storage module stores an interface reverse pre-congestion control threshold of the base station controller and the base transceiver station;
- the detecting module detects the reverse congestion degree of the interface between the base station controller and the transmitting and receiving base station, and outputs the detection result; the congestion control processing module: determines the reverse congestion degree of the interface between the base station controller and the transmitting and receiving base station outputted by the detecting module to reach the storage module When the pre-congestion control threshold is used, congestion control processing is performed on the interface between the base station controller and the base transceiver station.
- the BTS can reverse the ABIS interface in reverse when the ABIS interface has not reached congestion and is about to reach congestion.
- the control process effectively avoids data packet loss, thereby effectively avoiding the data transmission performance of the ABIS interface caused by data packet loss, the retransmitted data wastes air interface resources, and the retransmitted data increases the congestion pressure of the ABIS interface.
- the problem of the user satisfaction is poor.
- the embodiment of the present invention limits the AT by adopting a method of setting the RAB to be busy, limiting the transmission frequency of the AT access message, and adjusting the reverse MAC layer parameter of the AT traffic with low priority.
- the sending rate enables the BTS to provide differentiated services for different priority AT services, ensuring the quality of service for high-priority services.
- the threshold is removed. The phenomenon that the BTS is frequently started and the congestion control processing is stopped is avoided, and the system oscillation is effectively avoided. Therefore, the technical solution provided by the embodiment of the present invention achieves the purpose of improving the utilization of the air interface resources, improving the user satisfaction, and improving the achievability of the service quality.

- FIG. 2 is a schematic diagram of a base transceiver station according to an embodiment of the present invention. Mode for carrying out the invention
- the interface between the base station controller and the base transceiver station is reversely subjected to congestion control processing, that is, the interface between the base station controller and the base transceiver station is advanced in advance.
- congestion control processing By performing congestion control processing in the reverse direction, data packet loss can be effectively avoided, thereby avoiding various drawbacks such as wasted air interface resources and poor user satisfaction caused by data packet loss.
- the following is a detailed description of an embodiment of the present invention in which the interface between the base station controller and the base transceiver station is an interface between the BTS and the BSC, that is, the ABIS interface.
- the technical solution of the embodiment of the present invention is not limited to the ABIS interface.
- the embodiment of the present invention firstly needs to set a pre-congestion control threshold for the ABIS interface in reverse.
- the pre-congestion control threshold should ensure that when the congestion degree of the ABIS interface reaches the pre-congestion control threshold, the ABIS interface reverse has not reached congestion, that is, when When the congestion degree of the ABIS interface reaches the pre-congestion control threshold, the BTS does not perform data packet loss processing.
- the embodiments of the present invention do not limit the main body that implements the steps of the following methods, for example, the entity that performs the aggregation may be
- the BTS can also be other devices on the BTS side.
- the embodiments of the present invention will be described by taking B ⁇ S as an execution subject as an example in the following embodiments. .: .
- the setting of the pre-congestion control threshold corresponds to the method for the BTS to detect the reverse congestion degree of the ABIS interface. For example, when the pre-congestion control threshold is set to the bandwidth occupancy threshold of the ABIS interface, the BTS needs to detect the bandwidth occupancy of the ABIS interface; When the BTS service flow queue length threshold is set, the BTS needs to detect the BTS service flow queue length. When the pre-congestion control threshold is set to the BTS service flow buffer occupancy threshold, the BTS needs to detect the BTS service flow buffer occupancy rate.
- the pre-congestion control threshold in the embodiment of the present invention may include one or more of the foregoing thresholds. When the pre-congestion control threshold includes a plurality of the thresholds, the detection process of the BTS should also include a corresponding multiple detection process.
- the congestion control process of the ABIS interface should be reversed by reducing the transmission rate of the AT, and the ABIS interface is reversely congested.
- the degree is below the pre-congestion control threshold.
- the embodiment of the present invention also sets the ABIS interface reverse pre-congestion control cancellation threshold, and the value of the reverse pre-congestion control cancellation threshold should be less than the pre-congestion. The value of the control threshold.
- the method for reducing the transmission rate of the AT is as follows: setting the RAB (reverse activation indication) to the busy state, setting the RAB threshold to a predetermined value such as the minimum value, limiting the access frequency of the AT access message, and adjusting the reverse of the predetermined AT traffic flow.
- the embodiment of the present invention may adopt any of the foregoing methods to reduce the transmission rate of the AT, and may also adopt a method for reducing the transmission rate of the AT without making the reverse congestion degree of the ABIS interface not exceed the reverse pre-congestion control cancellation gate. In a limited time, another method is used to continue to reduce the AT transmission rate.
- the embodiment of the present invention may first adopt a method of setting the RAB to a busy state and setting the threshold of the RAB to a predetermined value, such as a minimum value.
- a method for limiting the frequency of accessing the AT of the AT is adopted. If the purpose is still not achieved, a method of adjusting the reverse MAC layer parameters of the predetermined AT traffic flow is adopted.
- Embodiments of the present invention provide three methods for measuring the degree of reverse congestion of an ABIS interface.
- Method 1 Detect the bandwidth usage of the ABIS interface.
- the inverse average rate of the air interface Raimve should be the ratio of the amount of data received by the BTS from the air interface to the detection period T during the detection period T.
- Set the bandwidth of the ABIS interface to Rabis, and the bandwidth usage of the ABIS interface is Rairave/Rabis.
- the embodiment of the present invention can set the detection period according to the actual situation of the network.
- the bandwidth occupancy rate of the ABIS interface should be between 0 and 1. The closer the bandwidth occupancy of the ABIS interface is to 1, the closer the ABIS interface is to congestion. .
- the pre-congestion control threshold that is, the bandwidth occupancy threshold of the ABIS interface should be less than 1.
- the instantaneous air interface reverse rate exceeds the bandwidth of the ABIS interface.
- the air interface reverse average rate Rairave cannot exceed the ABIS interface bandwidth Rabis, that is, the air interface reverse rate cannot continue to exceed the ABIS interface bandwidth Rabis for a long period of time.
- Method 2 Detect the length of the BTS service flow queue.
- any traffic flow queue overflow in the BTS indicates that the ABIS interface is congested in reverse. Therefore, detecting the BTS service flow queue length can be used as the detection of the ABIS interface reverse congestion.
- the measure of degree The closer the BTS service flow queue length is to the length of the traffic flow buffer, the closer the ABIS interface reverse is to congestion.
- the pre-congestion control threshold that is, the BTS service flow queue length threshold should be smaller than the length of the service flow buffer.
- Method 3 Detect the BTS service flow buffer occupancy rate.
- the length of the buffers of the service flows in the BTS may be different. Therefore, the thresholds of the service flows may be different.
- the embodiment of the present invention may define a BTS service for the service flow. Stream buffer occupancy, BTS service stream buffer occupancy BTS service stream queue length / BTS service stream buffer length. In this way, the BTS service flow buffer occupancy threshold corresponding to each service flow queue can be unified.
- the BTS service stream buffer occupancy should be between 0 and 1. The closer the BTS service stream buffer occupancy is to 1, the closer the ABIS interface is to congestion.
- the pre-congestion control threshold that is, the BTS service flow buffer occupancy threshold should be less than 1.
- the time to the congestion control is called the reflection time.
- the BTS should make the service flow queue length no longer increase.
- the air interface data can be filled in the reflection time, or the buffer data that is full during the reflection time can be sent, it is not suitable to measure the ABIS interface congestion by the second and third methods.
- the degree that is, if there are many concurrent traffic flows in the BTS, and the length of each traffic flow is small, the first method should be selected to detect the reverse congestion degree of the ABIS interface. Otherwise, the second type can be selected. And a third method to detect the degree of reverse congestion of the ABIS interface.
- the algorithm for the reverse congestion control of the ABIS interface in the embodiment of the present invention that is, the reverse congestion control process of the ABIS interface, is described below by taking the example of the ABIS interface bandwidth usage ratio and the BTS stream buffer occupancy rate.
- the pre-congestion control threshold corresponding to the bandwidth usage of the ABIS interface and the BTS traffic buffer occupancy rate is AbisOverFlowThresh
- the pre-congestion control cancellation threshold corresponding to the bandwidth usage of the ABIS interface and the BTS stream buffer occupancy rate is AbisStableThresh.
- the BTS triggers the ABES interface reverse congestion control process to limit the air interface reverse transmission rate.
- the congestion control process is cancelled, thereby avoiding the bandwidth of the ABIS interface.
- the reverse congestion control process of the ABIS interface can be divided into the following steps:
- Step 1 When the BTS detects that the reverse congestion degree of the ABIS interface exceeds AbisOverFlowThresh, that is, when the ABIS interface reverse congestion control is triggered, the RAB of the sector needs to be adjusted first, and the RAB is set to "busy" to request the AT to be lowered. Send rate.
- the RAB is a sector-level parameter that works for all ATs under the sector. Based on RevO
- the AT of the protocol reversion 0 (protocol version 0) performs the deceleration processing of the transmission rate according to the rate transition matrix; the AT based on the RevA (protocol reversion A, protocol version A) performs the deceleration processing of the transmission rate according to the reverse MAC layer algorithm.
- the embodiments of the present invention can implement different state transition matrix or reverse MAC layer parameters for different ATs and different service flows, so as to control the transmission rate of services of different priorities to reduce the transmission rate, thereby providing high priority services.
- Differentiating service features ensures the quality of service for high-priority services.
- the BTS sets the RAB according to the air interface reverse load, that is, if the air interface reverse load is not high, the RAB is set to "no busy", and then all ATs in the sector resume their transmit power. And data transmission rate.
- the RAB threshold can be set to limit the AT transmission rate in the sector. That is, when the ABIS interface reverse congestion control process is started, the RAB. threshold is set to The minimum value, so that ROT (rise over thermal) easily exceeds this gate, allowing the BTS to set the RAB to "busy". Similarly, when the BTS cancels the congestion control process, the BTS can be set to "BR" based on the reverse ROT (Rise Over Thermal) by restoring the RAB threshold. The RAB is set to "no busy,".
- step 1 cannot make the reverse congestion of the ABIS interface detected by the BTS not exceed
- Step 2 If a large number of ATs register at the same time, initiate a session request, or initiate a connection request, a large number of access messages may also impact the reverse traffic of the ABIS interface, such as when the system is upgraded, activities are held, and the morning is turned on, the ABIS is The reverse traffic of the interface causes an impact. In this way, when performing congestion control on the ABIS interface, it is also necessary to appropriately limit the access frequency of the AT access message to ensure access of the high priority AT.
- step 3 If you still cannot use the methods in steps 1 and 2 to prevent the BTS from detecting that the reverse congestion of the ABIS interface does not exceed AbisStableThresh, you need to go to step 3.
- Step 3 If the priority of the currently activated service flow is relatively high, when the RAB and the limit AT access message transmission frequency are set such that the reverse congestion degree of the ABIS interface still exceeds AbisStableThresh, the partial service flow needs to be selectively adjusted.
- the reverse MAC layer parameters are used to reduce the transmit power of a portion of the AT, thereby reducing the transmission rate of the corresponding traffic stream.
- the embodiment of the present invention can start congestion control processing for a part of the service flow with the largest traffic stream buffer occupancy rate.
- the specific method is as follows:
- the AN (access network) initiates a parameter negotiation process with the AT for the predetermined service flow, and limits the transmit power of the AT by reducing parameters such as the T2PInFlow of the AT.
- the BTS When the BTS sends data through the ABIS interface, it is scheduled according to the priority of each service flow. Therefore, the service flow with the largest traffic flow buffer occupancy rate is also the lower priority service flow. Therefore, the method can lower the priority.
- the low AT transmit power ensures that the AT with higher priority has higher transmit power and guarantees the quality of service of the AT with higher priority.
- Step 1 When the method of Step 1, Step 2, and Step 3 is used to make the reverse congestion degree of the ABIS interface detected by the BTS not exceed AbisStableThresh, firstly, the reverse MAC layer parameter setting of the AT needs to be restored, and then the AT access message is cancelled. The frequency limit, and finally, restore the RAB settings.
- the BTS provided by the embodiment of the present invention mainly includes: a storage module, a detection module, and a congestion control processing module.
- the storage module is mainly used to store the reverse pre-congestion control threshold of the ABIS interface.
- the reverse pre-congestion control threshold of the ABIS interface can be the bandwidth occupancy threshold of the ABIS interface, the BTS service flow queue length threshold, and the BTS service flow buffer occupancy threshold. One or more.
- the storage module can also store the ABIS interface reverse pre-congestion control cancellation threshold.
- the ABIS interface reverse pre-congestion control cancellation threshold should be less than the ABIS interface reverse pre-congestion control threshold.
- the ABIS interface reverse pre-congestion control cancellation threshold may also include multiple types, which respectively correspond to the above-mentioned various ABIS interface reverse pre-congestion control thresholds.
- the detection module should detect the degree of reverse pre-congestion of the ABIS interface based on the threshold stored in the storage module, such as the bandwidth usage of the ABIS interface, the BTS service flow queue length, and the BTS service flow buffer occupancy. The specific detection method is as described in the above method.
- the congestion control processing module is mainly used to perform congestion control processing on the ABIS interface when determining that the reverse congestion degree of the ABIS interface outputted by the detection module reaches the pre-congestion control threshold stored in the storage module, and in the process of congestion control processing, determining the detection module When the reverse congestion degree of the output ABIS interface does not exceed the pre-congestion control cancellation threshold stored in the storage module, the congestion control processing of the ABIS interface is canceled.
- the main operations of the congestion control processing module are implemented by the judgment sub-module, the congestion control processing sub-module, and the congestion control cancellation sub-module.
- the determining sub-module is mainly used to notify the congestion control processing sub-module to perform congestion control processing when determining that the reverse congestion degree of the ABIS interface output by the detecting module reaches the ABIS interface reverse pre-congestion control threshold stored in the storage module; After the sub-module performs the congestion control process, it determines that the reverse congestion degree of the ABIS interface output by the detection module does not exceed the ABIS interface reverse pre-congestion control cancellation threshold stored in the storage module, and notifies the congestion control cancellation sub-module to cancel the congestion control process.
- the ABIS interface When the congestion control processing sub-module receives the congestion control processing notification, the ABIS interface performs congestion control processing, and the specific congestion control processing may be to set the RAB to the busy state or set the RAB threshold to a predetermined value to request the AT to reduce the transmission rate.
