Fig. 5 A is please referred to, it illustrates the flow charts of the data transmission method of the data service of another exemplary embodiment of the present invention offer.The present embodiment is with the data transmission method of the data service for coming in the data transmission system of data service shown in FIG. 1 for example, this method including the following steps:
Step 501, the first equipment receives the data packet for carrying bandwidth information that the second equipment is sent, and bandwidth information includes at least the adjusting step of the transmission code rate and data service of the data packet.
After establishing data service between second equipment and mobile device, the second equipment sends data packet to corresponding first equipment of the mobile terminal.In general, the second equipment continuously transmits several data packets when sending data packet with identical transmission code rate, and the adjusting step of the transmission code rate and data service of the data packet is carried in each data packet.Wherein, the data bits that code rate is unit time transmission when server sends data packet is sent, adjusting step is the step-length for the transmission code rate that server adjusts the data service.
Correspondingly, the first equipment receives the data packet for carrying bandwidth information that the second equipment is sent.
Step 502, the first equipment determines suggestion code rate according to the load eated dishes without rice or wine corresponding with data service and bandwidth information.
First equipment can determine whether the transmission code rate for eating dishes without rice or wine corresponding each data service needs to adjust according to the load eated dishes without rice or wine.When the transmission code rate for determining a data service needs to adjust, the suggestion code rate of the data service is determined, and the suggestion code rate is sent to the corresponding server of the data service, so that server sends the data service according to suggestion code rate.
Further, when the load eated dishes without rice or wine reaches the first predetermined threshold, show that the load eated dishes without rice or wine is excessively high and easily congestion of eating dishes without rice or wine occur, the first equipment can reduce the load eated dishes without rice or wine at this time, to avoid there is congestion of eating dishes without rice or wine.When the load eated dishes without rice or wine is lower than the second predetermined threshold, show that the bandwidth of air-interface utilization rate eated dishes without rice or wine is low, the load eated dishes without rice or wine can be improved in the first equipment at this time, to improve the utilization rate of bandwidth of air-interface.
Wherein, the first predetermined threshold and the second predetermined threshold are usually set by system developer, and the first predetermined threshold is greater than the second predetermined threshold.
Optionally, this step determines suggestion code rate according to the load and bandwidth information eated dishes without rice or wine, can be by such as scheming
Several sub-steps shown in 5B are realized.
Step 502a subtracts the first predetermined threshold using the load eated dishes without rice or wine when the load eated dishes without rice or wine reaches the first predetermined threshold, will obtain difference multiplied by the bandwidth of air-interface that this is eated dishes without rice or wine and obtains the adjustment numerical value of the occupied bandwidth eated dishes without rice or wine.
For example, first predetermined threshold is 0.8, when the load eated dishes without rice or wine is 0.9, the regulation 0.1 for the occupied bandwidth that the first predetermined threshold 0.8 is eated dishes without rice or wine is subtracted using the load 0.9 eated dishes without rice or wine, the adjustment numerical value of the occupied bandwidth eated dishes without rice or wine is obtained as 10Mbps multiplied by the bandwidth of air-interface 100Mbps to eat dishes without rice or wine using the regulation 0.1 of occupied bandwidth, that is to say, that the occupied bandwidth eated dishes without rice or wine needs to turn down 10Mbps.
Step 502b is subtracted the load eated dishes without rice or wine using the first predetermined threshold, obtained difference is obtained the adjustment numerical value of the occupied bandwidth eated dishes without rice or wine multiplied by the bandwidth of air-interface that this is eated dishes without rice or wine when the load eated dishes without rice or wine is lower than the second predetermined threshold.
For example, first predetermined threshold is 0.8, first predetermined threshold is 0.6, when the load eated dishes without rice or wine is 0.4, the regulation 0.4 for the occupied bandwidth that the load 0.4 eated dishes without rice or wine is eated dishes without rice or wine is subtracted using the first predetermined threshold 0.8, the adjustment numerical value of the occupied bandwidth eated dishes without rice or wine is obtained as 40Mbps multiplied by the bandwidth of air-interface 100Mbps to eat dishes without rice or wine using the regulation 0.4 of occupied bandwidth, that is to say, that the occupied bandwidth eated dishes without rice or wine needs that 40Mbps is turned up.
It should be noted is that, the occupied bandwidth eated dishes without rice or wine according to the carry calculation eated dishes without rice or wine needs the numerical value adjusted that can realize by a variety of calculations, such as, those of ordinary skill in the art can also convert calculation involved in step 502a and 502b to calculate the numerical value that the occupied bandwidth eated dishes without rice or wine needs to adjust, and this embodiment is not repeated.
Step 502c, according to the adjustment numerical value of eat dishes without rice or wine corresponding data traffic information and occupied bandwidth, the adjustment numerical value for determining the bandwidth of data service, according to adjusting step, the bandwidth of data service adjustment numerical value and bandwidth information in transmission code rate calculate the suggestion code rate of the data service.

Fig. 6 A is please referred to, it illustrates the flow charts of the data transmission method of the data service of another exemplary embodiment offer of the invention.The present embodiment is with the data transmission method of the data service for coming in the data transmission system of data service shown in FIG. 1 for example, this method including the following steps:
Step 601, the first equipment determines according to the load eated dishes without rice or wine corresponding with data service and is used to indicate the adjustment information that the transmission code rate to data service is adjusted, which includes instruction information, which is sent to the second equipment.
Optionally, this step can be realized by following possible three kinds of embodiments.
In the first possible embodiment, when the load eated dishes without rice or wine reaches third predetermined threshold, the first equipment, which sends to be used to indicate to the second equipment, turns down the instruction information for sending code rate.
For example, when the load eated dishes without rice or wine is 0.9 and third predetermined threshold is 0.8, the load eated dishes without rice or wine is less than third predetermined threshold, and the first equipment, which sends to be used to indicate to the second equipment, turns down the instruction information for sending code rate.
In second of possible embodiment, when the load eated dishes without rice or wine is less than four predetermined thresholds, the first equipment, which sends to be used to indicate to the second equipment, turns down the instruction information for sending code rate.
For example, when the load eated dishes without rice or wine be 0.1 and the 4th predetermined threshold be 0.6 when, less than the 4th predetermined threshold 0.6, the first equipment, which sends to be used to indicate to the second equipment, is turned up the instruction information for sending code rate for the load 0.1 eated dishes without rice or wine.
In the third possible embodiment, when the load eated dishes without rice or wine reaches the 4th predetermined threshold and when less than three predetermined thresholds, the first equipment, which sends to be used to indicate to the second equipment, maintains to send the constant instruction information of code rate.
For example, third predetermined threshold is 0.8,4th predetermined threshold is 0.6, when the occupancy for obtaining interface-free resources is 0.7, the load 0.7 eated dishes without rice or wine is greater than the 4th predetermined threshold 0.6 and the load 0.7 eated dishes without rice or wine is less than third predetermined threshold 0.8, and the first equipment, which sends to be used to indicate to the second equipment, maintains to send the constant instruction information of code rate.
It should be noted is that third predetermined threshold and the 4th predetermined threshold are set by system developer, and third predetermined threshold is greater than the 4th predetermined threshold.
Step 602, the adjustment information that the transmission code rate being used to indicate to data service that the second equipment receives that the first equipment is sent is adjusted, the transmission code rate of the data service, the adjustment information are adjusted according to adjustment information
Including indicating information.
Optionally, this step can be realized by following possible three kinds of embodiments.
In the first possible embodiment, when instruction information, which is used to indicate, turns down transmission code rate, the second equipment turns down the transmission code rate of data service, and the data packet of data service is sent according to transmission code rate adjusted.
When the instruction information that the second equipment receives, which is used to indicate, turns down transmission code rate, the transmission code rate of data service is turned down into first predetermined adjusting step.Wherein, first predetermined is usually set by system developer.
For example, the current transmission code rate of data service is 1024Kbps, when the second equipment, which receives, is used to indicate the instruction message for turning down transmission code rate, code rate 1024Kbps will be sent and turn down an adjusting step 64Kbps, and send the data packet of the data service according to transmission code rate 960Kbp adjusted.
In second of possible embodiment, when indicating that information is used to indicate height-regulating transmission code rate, the transmission code rate of data service is turned up in the second equipment, and the data packet of data service is sent according to transmission code rate adjusted.
When the instruction information that the second equipment receives, which is used to indicate height-regulating, sends code rate, second predetermined adjusting step is turned up in the transmission code rate of data service.Wherein, second predetermined is usually set by system developer.
For example, the current transmission code rate of data service is 1024Kbps, when the second equipment, which receives, is used to indicate the instruction message that transmission code rate is turned up, code rate 1024Kbps will be sent, an adjusting step 64Kbps is turned up, and send the data packet of the data service according to transmission code rate 1088Kbps adjusted.
In the third possible embodiment, when instruction information, which is used to indicate, maintains transmission code rate constant, the second equipment is according to the last data packet for sending code rate transmission data service used.
For example, it is 1024Kbps that current second equipment, which sends the transmission code rate of data service,.When the second equipment receive be used to indicate maintenance send code rate it is constant when, the second equipment sends the data packet of the data service still according to code rate 1024Kbps is sent.
In summary, the data transmission method of data service provided in this embodiment, by determining instruction information according to the transmission code rate of the load and the data service eated dishes without rice or wine, so that server adjusts the transmission code rate of the data service according to instruction information, realize the control for the load eated dishes without rice or wine, therefore it solves the problems, such as the congestion of eating dishes without rice or wine that the control mode of the data service provided in the related technology transmission code rate easily causes base station, improves the efficiency of transmission eated dishes without rice or wine.
Optionally, the first equipment can provide bandwidth safeguard when forwarding the data packet of data service for the data service.Specifically, can be realized by several steps as shown in Figure 6B.
Step 603, the data packet for carrying bandwidth information that the second equipment is sent is received, the transmission code rate in the bandwidth information is read.
Step 604, the interface-free resources to match with transmission code rate are distributed for business datum, the bandwidth of the interface-free resources of distribution is greater than or equal to the transmission code rate.
When distributing the interface-free resources to match with transmission code rate for business datum, can be accomplished in several ways.
For example, being that the business datum distributes interface-free resources according to the predetermined ratio of the transmission code rate of business datum.For example, when predetermined ratio is 1.2, when the transmission code rate of business datum is 512Kbps, the first equipment is that the bandwidth of the interface-free resources of business datum distribution is 614.4Kbps.
For another example, be the broadband of resource of data service distribution and the difference of the transmission code rate of the data service is predetermined value, and predetermined value can be set by system developer.For example, when predetermined value is 200Kbps, when the transmission code rate of business datum is 512Kbps, then it is 712Kbps that the first equipment, which is the bandwidth of the interface-free resources of business datum distribution,.
By the interface-free resources to match for business datum distribution with the transmission code rate, bandwidth safeguard is provided for the business datum.
It should be noted is that, in the case where the second equipment is core network element, when core network element is greater than transmission code rate of the core network element to the first device forwards data packet from the reception code rate of server received data packet, core network element equipment can cache the data packet not forwarded.When core network element is less than transmission code rate of the core network element to the first device forwards data packet from the reception code rate of server received data packet, core network element can obtain the data packet of the data service from local cache or obtain the data packet of the data service from server.
In addition, avoiding by the control to the load eated dishes without rice or wine and eating dishes without rice or wine the problem of congestion occur.When data service is video traffic, reduces the received delay of mobile device side video data packet, reduce the caching and Caton of video.
In addition, by when the load eated dishes without rice or wine is lower, first equipment is by sending the suggestion code rate for being used to indicate and being turned up and sending the instruction information of code rate or determine higher than currently transmitted code rate to the second equipment, so that the transmission code rate of the second equipment height-regulating data service, improves the utilization rate of interface-free resources.
