The entire contents of this application are incorporated herein by reference. Technical field

The present invention relates to the field of communications technologies, and in particular, to a data transmission control method, apparatus, and system.

Background technique

With the development of FMC (Fixed Mobile Convergence) technology, the use of IP (Internet Protocol) technology to carry 3G services has become a trend. In the prior art, a base station controller, such as an RNC (Radio Network Controller), is connected to a transmission network through a GE (Gigabit Ethernet) or FE (Fast Ethernet) link. The Node B (base station) can connect to the transmission network through the FE link, the E1 link, or the STM-1 (Synchronous Transport-1) link, or can also pass the N E1 and the transmission network. connection. In the signal transmission direction between the base station controller and the base station, the direction from the base station controller to the base station is referred to as the downlink direction, and the direction from the base station to the base station controller is referred to as the uplink direction.

In the 3G network, there are mainly three types of services: voice service, HSDPA service (High Speed Downlink Packet Access), and HSUPA service (high speed uplink packet access). The uplink and downlink traffic of the voice service is basically the same. The HSDPA service is mainly downlink traffic, while the HSUPA service is mainly uplink traffic. Therefore, different services have different requirements on the bandwidth of the uplink and downlink transmission links between the base station controller and the base station.

In order to reasonably allocate bandwidth for various services, the following two methods can be used in the prior art: Manner 1: In the uplink direction of the base station, different logical ports are allocated for voice services, HSUPA services, and signaling, and the uplink bandwidth of different services is restricted by limiting the logical ports. For example, if a physical port is an E1 port, the base station is connected to the base station controller through the E1 port. The logical port 0, the logical port 1 and the logical port 2 are bound to the physical port. At the same time, different transmission bandwidths are configured for each logical port, so that HSUPA services, voice services, and signaling respectively occupy the bandwidth of the logical port on which they are located for transmission.

Manner 2: In the uplink direction of the base station, assign the same logical port to the voice service, HSUPA service, and signaling, and set different transmission priority queues for different services. For example, the signaling is sent through the priority queue 0. The upstream traffic of the voice service is sent through the priority queue. The upstream traffic of the HSUPA service is sent through the priority queue. In this way, the bandwidth required for signaling and voice can be fully guaranteed. For the HSUPA service, it is also guaranteed to send its upstream traffic. Moreover, for the HSUPA service, the base station controller may feed back the frame loss information to indicate whether the base station needs to reduce the uplink traffic of the HSUPA service. In the prior art, there is a problem of bandwidth waste and low bandwidth utilization in a method of allocating bandwidth for various different services.

The technical solutions and advantages of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

In order to improve the uplink bandwidth utilization of the transmission link between the base station controller and the base station, as shown in FIG. 1, the first embodiment of the present invention provides a data transmission control system, including: a base station controller 12 and at least one base station 11, The base station 11 is connected to the base station controller 12 in a communicable manner.

The base station 11 is configured to send high speed uplink packet access service data to the base station controller 12, and obtain remaining cache time of the high speed uplink packet access service queue. When the remaining buffer time is less than the congestion time threshold, reducing the traffic of the high speed uplink packet access service; when the remaining buffer time is greater than the congestion recovery time threshold, increasing the high speed uplink Traffic for packet access services. The base station controller 12 is configured to receive the high speed uplink packet access service data sent by the base station 11.

In this embodiment, the base station controller includes but is not limited to RNC, CBSC (CDMA Centralized Base Station Controller) / GBSC (GSM Centralized Base Station Controller), etc., and may also include other wireless network controllers.

The data transmission control system of the embodiment of the present invention compares the remaining cache time of the acquired HSUPA service queue with the congestion time threshold and the congestion recovery time threshold respectively, and when the remaining cache time is less than the congestion time When the value is decreased, the traffic of the HSUPA service is decreased. When the remaining cache time is greater than the congestion recovery time threshold, the traffic of the HSUPA service is increased. As can be seen from the above description, the embodiment of the present invention dynamically adjusts the traffic of the HSUPA service on the base station side, that is, the traffic of the HSUPA service can be adjusted by the base station itself according to the foregoing determination result. The system improves the upstream bandwidth utilization of the transmission link between the base station controller and the base station.

Embodiment 2 of the present invention provides a data transmission control method. In the method according to the second embodiment of the present invention, in the uplink transmission scheduling direction of the base station, the same logical port is assigned to the voice service, the HSUPA service, and the signaling, and different services are sent through queues of different priorities of the same logical port. For example, signaling can be sent in the highest priority queue, and voice traffic is sent in the next highest priority queue. The HSUPA service is sent in the lowest priority queue.

As shown in FIG. 2, the method in the second embodiment of the present invention includes the following steps:

Step 21: On the base station side, the remaining cache time of the high-speed uplink packet access service queue is obtained by the base station.

In this step, the remaining cache time of the HSUPA service queue can be obtained as follows: First, the transmission rate of the high-speed uplink packet access service queue is obtained within a predetermined time. The predetermined time may be configured or stored in advance or arbitrarily set. The sending rate is a quotient of the number of bytes sent by the HSUPA service queue and the predetermined time within the predetermined time.

Then, the number of remaining caches of the high speed uplink packet access service queue is obtained. The number of remaining buffers is the difference between the total number of caches of the HSUAP service queue and the number of packets in the queue read at the time when the scheduled time is reached. The total number of caches of the HSUAP service queue may also be configured in advance.

Finally, the remaining cache time of the high speed uplink packet access service queue is obtained according to the number of remaining buffers. The remaining cache time can be calculated as follows:

The remaining cache time of the HSUPA service queue = (number of remaining caches * typical packet length) / transmission rate. The typical packet length may be a default value or may be preset.

Step 22: When the remaining buffer time is less than a congestion time threshold, the base station decreases the traffic of the high-speed uplink packet access service; when the remaining cache time is greater than a congestion recovery time threshold, the The base station increases the traffic of the high speed uplink packet access service.

In this step, when the remaining buffer time is less than the congestion time threshold, a congestion feedback message may be generated, so that the unit or module that receives the congestion feedback message in the base station may reduce the high speed uplink packet according to the message. The traffic of the access service does not reduce the traffic until the following congestion feedback recovery message is received. Similarly, when the remaining buffer time is greater than the congestion recovery time threshold, a congestion recovery feedback message may be generated, so that the unit or module that receives the congestion feedback recovery message in the base station may increase the high speed uplink according to the message. Packet access traffic, until received After the congestion feedback message is described, the traffic is no longer increased.

It can be seen that the method in the embodiment of the present invention compares the remaining cache time of the acquired HSUPA service queue with the congestion time threshold and the congestion recovery time threshold respectively on the base station side, and when the remaining cache time is When the congestion time is less than the congestion time, the traffic of the HSUPA service is decreased. When the remaining cache time is greater than the congestion recovery time threshold, the traffic of the HSUPA service is increased. Therefore, compared with the prior art, the embodiment of the present invention avoids the defects of unsatisfactory response and low bandwidth utilization caused by adjusting the HSUPA traffic according to the information fed back by the base station controller side in the prior art, and improves the base station. The upstream bandwidth utilization of the transmission link between the controller and the base station.

In addition, in order to perform the method of improving the uplink bandwidth utilization of the transmission link between the base station controller and the base station, some pre-configuration may be performed on the base station side. For example, it can include:

(1) Setting the congestion time threshold and the congestion recovery time threshold. The congestion time threshold indicates a time threshold at which the transmitted HSUPA service queue is about to be congested, and the congestion recovery time threshold indicates that the traffic of the HSUPA service is reduced to a time threshold required for congestion to occur. These two values can be set arbitrarily according to ^ r.

(2) Adding an identity to a queue that transmits the high speed uplink packet access service. As described above, in the method according to the second embodiment of the present invention, queues of different services are transmitted according to different priorities. However, in order to increase the flexibility of controlling the uplink transmission signal of the base station, in the embodiment of the present invention, a queue identifier may be added to the HSUPA service queue to facilitate control of the traffic of the HSUPA service. That is to say, before sending the queue of each service, the base station can determine that the current queue is a high-speed uplink packet access service queue according to the queue identifier, and then perform corresponding flow control.

(3) setting a linear queue number for the high speed uplink packet access service queue, and storing a correspondence between the linear queue number of the high speed uplink packet access service and the high speed uplink packet access service user.

After the setting is performed, the congestion feedback message in the foregoing step 22 may carry a linear queue number and a congestion identifier that are about to be congested, and the congestion feedback recovery message may include a linear queue number that needs to increase traffic and congestion recovery. Identification; wherein the congestion identifier is used to indicate an upcoming flow The traffic congestion is reduced, and the traffic of the HSUPA service needs to be reduced. The congestion recovery identifier is used to indicate that the traffic congestion is restored, and the traffic of the HSUPA service can be increased. Then, according to the linear queue number in the congestion feedback message or the congestion feedback recovery message and the stored correspondence, the traffic of the HSUPA service of the corresponding user may be reduced or increased.

For the uplink direction of the base station, for the voice service, the HSUPA service, and the signaling to allocate different logical ports, the method of limiting the uplink bandwidth of the different services by limiting the logical port, if the transmission bandwidth of the three logical ports is configured If the sum of the physical bandwidth of the port is equal to the bandwidth of the port, the bandwidth of the remaining part of the voice service cannot be used by the HSUPA service. Therefore, the physical port bandwidth cannot be reused between different services, and the bandwidth utilization is low. With the method according to the second embodiment of the present invention, in the uplink transmission scheduling direction of the base station, the same logical port is assigned to the voice service, the HSUPA service, and the signaling, and different services are sent through queues of different priorities of the same logical port. The physical port bandwidth can be reused between different services. When the voice traffic is small, the HSUPA service can fully utilize the remaining bandwidth of the entire port to improve bandwidth utilization.

For the method of reporting the frame loss by the base station controller to indicate that the base station reduces the transmission traffic of the HSUPA, the base station controller feeds back the frame loss information to the base station to receive the feedback frame loss information, and then the base station starts to reduce the traffic of the HSUPA service, and the whole Frame dropping occurs during the process. If these frames are to be retransmitted, bandwidth will be wasted and the bandwidth utilization will be low.

By directly adjusting the transmission traffic of HSUPA when the transmission traffic of HSUPA is about to fill the remaining bandwidth of the entire port, the frame dropping phenomenon caused by the HSUPA service being too large is reduced or avoided. At the same time, when the voice traffic is large, the HSUPA service can give bandwidth to the voice service. Therefore, the method according to Embodiment 2 of the present invention improves the uplink bandwidth utilization of the transmission link between the base station controller and the base station.

A person skilled in the art can understand that all or part of the process of implementing the above embodiment method can be completed by a computer program to instruct related hardware, and the program can be stored in a computer readable storage medium. In execution, the flow of an embodiment of the methods as described above may be included.
