Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Among the present invention, during the communication terminal access external data, the signatory bandwidth of the gateway device obtaining communication terminal in the cdma network, bandwidth and the signatory bandwidth to communication terminal current data flow compares then, determines the processing to the transmission data.
When communication terminal in the cdma network and external network interaction data, gateway device is a data transmission set, and as PDSN/FA etc., according to the QoS architectural framework of transfer of data, gateway device is fit to the data flow bandwidth is controlled very much.
Communication terminal when signatory, the maximum bandwidth of can contracting and guarantee bandwidth.Maximum bandwidth is meant the maximum data flow of transmission each second, and promptly cdma network allows communication terminal and outer data network to carry out mutual maximum data flow; Guaranteeing that bandwidth is meant can guarantee the master data flow that transmits each second, and promptly assurable communication terminal of cdma network and outer data network carry out mutual master data flow.Maximum bandwidth should be not less than the assurance bandwidth.When gateway device and communication terminal connect passage, the maximum bandwidth of obtaining communication terminal unit contractual and assurance bandwidth.Gateway device can be by carrying out alternately the maximum bandwidth of obtaining communication terminal unit contractual and assurance bandwidth with the equipment that stores the signatory bandwidth of communication terminal; Also can store database, the maximum bandwidth of obtaining communication terminal unit contractual and the assurance bandwidth of the signatory bandwidth of communication terminal by inquiry.
Fig. 2 is a data traffic bandwidth control flow chart, and as shown in Figure 2, the implementation procedure of the bandwidth of controlling the data flows may further comprise the steps:
Step 203: the current data flow bandwidth of the communication terminal of gateway device judgement and mutual these data of outer data network, whether greater than the signatory maximum bandwidth of this communication terminal that obtains in advance, if then execution in step 205; Otherwise, execution in step 206.Above-mentioned communication terminal is meant has set up interface channel with gateway device, and the current communication terminal that carries out data interaction with outer data network.
Step 204: gateway device judges whether self is in congestion state, if then execution in step 205; Otherwise, execution in step 206.
Step 205: gateway device abandons data.
Step 206: gateway device reduces the priority of data, according to the priority after reducing, transmits this data then, promptly when gateway device can send the data of the priority after priority is to reduce, transmits this data.
Step 207: gateway device is transmitted data.
Gateway device is transmitted data and is meant that gateway device sends data to communication terminal or external network, if gateway device receives is upstream data, then gateway device sends data to outer data network; If what gateway device was received is downlink data, then gateway device sends data to communication terminal.
In actual applications, the uplink and downlink data traffic of communication terminal can be inconsistent, and therefore the bandwidth of the uplink and downlink data traffic of communication terminal can be set respectively.Communication terminal is when signatory, up maximum bandwidth (MaxBitUp can contract, Maximum bit rate for uplink), up assurance bandwidth (GuaBitUp, Guaranteed bit rate for uplink), descending maximum bandwidth (MaxBitDown, Maximum bitrate for downlink) and descending guarantee bandwidth (GuaBitDown, Guaranteed bit rate fordownlink).Up maximum bandwidth is meant the maximal uplink flow of transmission each second, and promptly cdma network allows the maximum data flow that communication terminal sends to outer data network; Uply guarantee that bandwidth is meant and to guarantee the flow of line data basically that transmits each second, be i.e. the master data flow that sends to outer data network of the assurable communication terminal of cdma network; Descending maximum bandwidth is meant the maximum downstream data traffic of transmission each second, and promptly cdma network allows the maximum data flow that outer data network sends to communication terminal; The descending guarantee bandwidth is meant can guarantee the basic downlink data flow that transmits each second, and promptly cdma network guarantees the master data flow that outer data network sends to communication terminal.
Guarantee bandwidth and uplink and downlink maximum bandwidth at different uplink and downlink, stand good according to the described data traffic bandwidth of Fig. 2 control flow, when only gateway device was received upstream data, the bandwidth that guarantees related in the flow process was up assurance bandwidth, and maximum bandwidth is up maximum bandwidth; When gateway device was received downlink data, the bandwidth that guarantees that relates in the flow process was the descending guarantee bandwidth, and maximum bandwidth is descending maximum bandwidth.
In addition, for realizing the resource reservation of gateway device, before gateway device and communication terminal connect passage, can at first compare the summation of assurance bandwidth and the transfer capability of self, if guarantee that the bandwidth summation is less than the gateway device transfer capability, gateway device and the communication terminal passage that directly connects then, or further, gateway device carries out authentication by the Radius server to communication terminal earlier, if communication terminal is by authentication, gateway device again with the communication terminal passage that directly connects; Be not less than the gateway device transfer capability if guarantee the bandwidth summation, then gateway device refusal and the communication terminal passage that connects.Above-described assurance bandwidth summation is meant the assurance bandwidth sum of having set up each communication terminal of interface channel with gateway device.
When the signatory different uplink and downlink of communication terminal guarantee bandwidth, then above-mentioned assurance bandwidth summation is up assurance bandwidth summation and descending guarantee bandwidth summation sum, promptly set up the up assurance bandwidth sum of each communication terminal of interface channel with gateway device, the descending guarantee bandwidth sum of above-mentioned each communication terminal, the addition result of up then assurance bandwidth sum and descending guarantee bandwidth sum; Or guarantee the summation of bandwidth sum corresponding to the uplink and downlink of having set up each communication terminal of interface channel with gateway device, promptly the uplink and downlink of above-mentioned each communication terminal guarantee the addition result of bandwidth sum.
