Embodiment

In an embodiment of the present invention, be divided into a plurality of sub-channels by the IP path that each of Node B side is used for service access, and this sub-channel only carries a kind of data to be transmitted of type of service, thereby can be by the bandwidth resources under the control IP transmission means, make the transmission of data of various types of traffic obtain rational planning control, thereby make that the bandwidth resources on the IP are reasonably distributed.

In order to make those skilled in the art understand technical scheme of the present invention better, embodiments of the invention are described in further detail below in conjunction with drawings and embodiments.

As shown in Figure 2, be the method flow diagram that business bandwidth resource in the embodiments of the invention distributes, the step of this method comprises:

Step 11, the IP path that is used for service access of Node B side is divided into a plurality of sub-channels; In the present embodiment, can support the type of service of data to be transmitted according to operator's configuration, the IP path that each of Node B side is used for service access is divided into a plurality of sub-channels, for example available PATH1, PATH2 and PATH3 represent three different sub-channels respectively, the number of this sub-channel can be set in advance according to the number of the type of service of data to be transmitted, for example when the data to be transmitted of three kinds of types of service, the IP path that is used for service access can be divided into three sub-channels, this sub-channel takies certain bandwidth resources separately, under the certain situation of total bandwidth, the big I of the shared bandwidth of each sub-channel is set according to actual conditions.

Business in this step can comprise: R4-rt business (the R4 real time business is as speech business), R4-nrt (the R4 non-real-time service is as the web page browsing business), R5-nrt (the R5 non-real-time service is as the file transfer protocol (FTP) downloading service) etc. also are not limited to this;

Step 12, set up the one-to-one relationship of type of service of sub-channel and transmission data;

Each sub-channel after just dividing is only supported a kind of data of type of service, for example PATH1 supports the data of R4-rt type of service, PATH2 supports the data of R4-nrt type of service, and PATH3 supports the data of R5-nrt type of service, and the number of sub-channel and type of service also are not limited to this.

When setting up this corresponding relation, can this corresponding relation be set according to the bandwidth and the required bandwidth of service accessing bearing of sub-channel, just set up one-to-one relationship according to the bandwidth of the sub-channel bandwidth required with transmitting data, for example the bandwidth of the required comparable video traffic of bandwidth of speech business is low, therefore, when setting up this corresponding relation, sub-channel that can bandwidth is big is corresponding with video traffic, and the sub-channel that bandwidth is low a little is corresponding with speech business.Thereby make that the bandwidth resources on the IP are reasonably distributed.

Step 13, when service access, according to the type of service of data to be transmitted and this corresponding relation, select the sub-channel corresponding to carry data to be transmitted with type of service.

In the present embodiment, can carry TNL (the Transport LayerAddress that sets up in the message by the Iub mouthpiece, the transport layer address) Qos (Quality of service, quality of service) parameter is transmitted the type of service of data to be transmitted, owing in step 12, set up the one-to-one relationship of the type of service of sub-channel and data to be transmitted, therefore the user can be by the foundation of this TNL Qos parameter as the chooser path, the same IE that also can select other (Information Element, message element) transmits the type of service of each data carried by data on the Iub mouth.

As shown from the above technical solution, the realization by bandwidth control under the IP carrying transmission means make the transfer of data of various types of traffic obtain rational planning control, and the bandwidth resources in the IP carrying has obtained rational distribution.

When the corresponding relation of being set up in adopting step 12 selects the sub-channel corresponding with the type to carry these data, may appear at the sub-channel of the data to be transmitted of a plurality of carrying identical services types, for example PATH1 and PATH2 support the data of R4-rt type of service, at this moment, inequality for fear of the service bearer bandwidth resource allocation, and the Network Transmission that causes is unstable and the use that makes it possible to the largest optimization resource, then need to consider the load sharing of bandwidth, this load sharing is just considered the bandwidth situation of sub-channel, for example can consider, and select the many sub-channel carrying transmission data of remaining bandwidth from the remaining bandwidth of sub-channel.

Need judge whether to have the sub-channel of the data to be transmitted of a plurality of carrying identical services types this moment, just needs execution in step 14;

Whether step 14, detection have the sub-channel of the data to be transmitted of a plurality of carrying identical services types, if, execution in step 15, otherwise, execution in step 17;

Just, when under detecting the same IP path that is used for service access, having the sub-channel of many data to be transmitted that carry the identical services type, need execution in step 15;

Step 15, according to the remaining bandwidth of sub-channel the priority of sub-channel is set, execution in step 16 then;

Priority in this step is meant that this sub-channel is selected to carry the priority of transmission data, the high more carrying transmission data to be transmitted that then is selected at first of priority.

The bandwidth of each service accessing bearing can obtain by following two kinds of methods:

1) calculates for the transmission format set (Transport Format Set) of traditional transmission bearer (as the R4 service bearer) by this carrying;

Wherein, the bandwidth calculation of conventional transmission carrying:

Conventional transmission carrying bandwidth, Bits;

Number Of Transport Blocks (i transformat piece number);

Transport Block Size (the transmission block size, Bits);

TTI:Transmission Time Interval (the transmission intercal time, ms)

${\mathrm{BW}}_{{\mathrm{CT}}_{r}B}=\frac{1000*\mathrm{Max}(N_{{\mathrm{ofTB}}_i}*S_{{\mathrm{TB}}_i})}{\mathrm{TTI}}$ Formula (1)

(2) use this assurance bit rate quantity (MAC-hs Guaranteed Bit Rate) that is carried on the per second transmission of eating dishes without rice or wine to add that the bandwidth reserved of eating dishes without rice or wine calculates for the relevant transmission bearer (as Mac-d Flow) of HSDPA (high speed downlink packet access);

The transmission bearer bandwidth calculation that HSDPA is relevant:

The transmission bearer bandwidth that HSDPA is relevant, Bits;

MAC-hs Guaranteed Bit Rate (the assurance bit rate that belongs to i formation of same transmission bearer, Bits);

L _Resv: the bandwidth reserved of eating dishes without rice or wine, Bits;

${\mathrm{BW}}_{{\mathrm{HT}}_{r}B}=\underset{i=0}{\overset{i}{\mathrm{\Σ}}}{\mathrm{GBR}}_{Q_i}+L_{\mathrm{resv}}$ Formula (2)

Each service bearer corresponding bandwidth can be obtained by above-mentioned two kinds of methods, and, the remaining bandwidth on the sub-channel can be obtained according to predefined total bandwidth.Can set up in the message by carrying in the present embodiment, under the conventional transmission carrying beared information relevant, increase new IE parameter and transmit the bandwidth of carrying, just be used for transmitting the required bandwidth of transmission data with HSDPA at the Iub mouthpiece.

Because by selecting the many sub-channels of remaining bandwidth, influence minimum to the transmission data in the time of can guaranteeing to happen suddenly, therefore in an embodiment of the present invention, can this priority be set according to remaining bandwidth, for example the remaining bandwidth of this sub-channel is many more, what then priority can be provided with is high more, just can select by the situation of the bandwidth of the current use of sub-channel, the remaining bandwidth of this sub-channel is the total bandwidth and the difference of utilized bandwidth of sub-channel just, only introduce the situation that priority is set according to the situation of remaining bandwidth below, but also be not limited to this, also can priority be set, for example the situations such as ratio of utilized bandwidth and total bandwidth by other modes.

Step 16, the sub-channel carrying data to be transmitted that selection priority is high;

In the present embodiment, can carry out the step of selecting the high sub-channel of priority by following method.

Step 161, all IP Port (port) of Node B side are gone up the type of service classification of the sub-channel of bearer service according to the data to be transmitted of carrying, construct chained list;

Step 162, when service access, according to RNC IP address lookup routing table in the Iub port service link establishment message, in this chained list, find out all sub-channels of routing iinformation coupling, and select the high sub-channel of priority to carry data to be transmitted;

Just according to all sub-channels that find out, compare the remaining bandwidth of these sub-channels then, and select the maximum sub-channel of remaining bandwidth to carry this data to be transmitted, on this sub-channel, distribute bandwidth then, if remaining bandwidth is enough, then service bearer bandwidth resource allocation success.

If have the situation (bandwidth is not enough) that its corresponding professional sub-channel can't insert or do not find corresponding professional sub-channel, at this moment can be according to RNC IP address lookup routing table in the Iub port service link establishment message, in the chained list of acquiescence business, find out all sub-channels of routing iinformation coupling, relatively the remaining bandwidth of these all sub-channels selects the sub-channel of priority height (remaining bandwidth is maximum) to carry data to be transmitted; If the sub-channel in sub-channel that carries corresponding business and acquiescence business all can't distribute bandwidth, then be considered as the failure of service bearer bandwidth resource allocation.

Step 17, selection are carried this data to be transmitted with the unique corresponding sub-channel of the type of service of data to be transmitted.
