Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
When having data service to initiate, can determine the packetization types and the packaging time length of business datum when terminal room is consulted media channel, at present the packetization types that adopts have voice G.711, G.722, G.723 wait video H261, H263, H264 etc.Have fixed-bandwidth for certain packetization types and packaging time length, as shown in the table:
| Type | RTP wraps number/per second | Bit rate (K) | Ethernet bag load | The IP load | The voice packet load | Total load (K) | Unidirectional bandwidth (K) | The unidirectional RTCP that adds | Two-way bandwidth (K) |
| G.711 (5ms) | 200.00 | 64 | 8 | 40 | 40.00 | 98.00 | 156.80 | 164.64 | 313.60 |
| G.711 (10ms) | 100.00 | 64 | 8 | 40 | 80.00 | 138.00 | 110.40 | 115.92 | 220.80 |
| G.711 (15ms) | 66.67 | 64 | 8 | 40 | 120.00 | 178.00 | 94.93 | 99.68 | 189.87 |
| G.711 (20ms) | 50.00 | 64 | 8 | 40 | 160.00 | 218.00 | 87.20 | 91.56 | 174.40 |
| G.729 (10ms) | 100.00 | 8 | 8 | 40 | 10.00 | 68.00 | 54.40 | 57.12 | 108.80 |
| G.729 (20ms) | 50.00 | 8 | 8 | 40 | 20.00 | 78.00 | 31.20 | 32.76 | 62.40 |
| G.723.1 (30ms) | 33.33 | 6.3 | 8 | 40 | 23.63 | 81.63 | 21.77 | 22.855 | 43.53 |
Table 1
In order to guarantee speech quality, the Data-carrying net needs enough bandwidth, for example one the tunnel calls out employing G723.1 (30ms) packing, and the Data-carrying net needs to reserve unidirectional 20kps, the bandwidth of two-way 40kps to this conversation at least.If data network only provides the bandwidth less than 40kps, speech quality will be affected, and the clear and discontinuous phenomenon of aphthenxia can occur.Tentation data bearer network bandwidth is 100M, and G723.1 (30ms) packing is all adopted in all callings, and then when 2500 the tunnel called out, bandwidth had just been taken in theory; Surpass 2500 the tunnel if insert to call out, the data packet loss will inevitably occur, and along with inserting many more that call number surpasses, it is severe more that the Qos of conversation can descend; If insert quantity less than 2500 the tunnel, voice quality will be fine, so the present invention just controls the Qos that inserts conversation by the access bandwidth control method.
As shown in Figure 1, the present invention's method of controlling Qos specifically may further comprise the steps:
101, according to the network service quality demand of business, the bandwidth of configuration data business under various packetization types and packaging time length.This configured bandwidth generally all surpasses the theoretical bandwidth value, can in time adjust according to the congestion condition of Data-carrying net.
102, session is initiated, and calculates the shared bandwidth of current business according to above-mentioned configured bandwidth.
103, calculate the required bandwidth of above-mentioned session and current occupied bandwidth and.
104, more above-mentioned bandwidth and with the size of the Data-carrying network bandwidth, if the former is greater than the latter, then refusal inserts session, otherwise allows to insert session.
Above-mentioned Data-carrying net is NGN or 3G network.Because NGN control separates with carrying, signaling is walked different routes with medium, also can walk different subnets, so generally in the control operation of edge media gateway side enforcement to Qos, the control signaling is sent by the switch control device that is in core net.Can also control Qos at fringe access gateway, as the SBC/BGW among the NGN, because in terminal, SBC is exactly Softswitch, so also can adopt the calling of said method control terminal in the SBC side, guarantees the Qos of every business.
Simultaneously, in NGN or 3G network, there are some data services not have fixing theoretical bandwidth, said method is uncontrollable to this situation, but can in media gateway, carry out media flow control, just only allow the data of what flow to pass through for how many bandwidth it disposes, so just can guarantee the Qos of data service.Like this, the present invention can well guarantee all professional Qos of NGN or 3G in conjunction with bandwidth access control and media flow control method.
Be one embodiment of the present of invention below, implementation method is as described below:
Step 1, according to the Qos demand of business, the bandwidth of configuration data business under various packetization types and each duration generally all surpasses the theoretical bandwidth value.As table 2:
| Packetization types | Packaging time length | Bandwidth value (kps) |
| G711 | 5ms | 157 |
| G711 | 10ms | 111 |
| G711 | 15ms | 95 |
| G729 | 10ms | 55 |
| G729 | 15ms | 32 |
| ... | ... | ... |
Table 2
When step 2, session initiation, the Qos control module is calculated present occupied bandwidth, calculates according to table 3:
| Packetization types | Packaging time length | Counter |
| G711 | 5ms | Counter |
| G711 | 10ms | Counter |
| G711 | 15ms | Counter |
| G729 | 10ms | Counter |
| G729 | 15ms | Counter |
| ... | ... | ... |
Table 3
Computing formula is: occupied bandwidth=∑ (counter in the table 3) * (corresponding bandwidth in the table 2)
The bandwidth statistical value that this formula calculates is exactly current occupied bandwidth.
Step 3, calculate current occupied bandwidth and the session bandwidth that needs to insert and.
Step 4, more above-mentioned bandwidth and with the size of bearer network bandwidth, if bandwidth and wide greater than the Data-carrying guipure, just refusal inserts session, guarantees that the session that has inserted has enough bandwidth; Otherwise allow to insert session.If allow to insert session, then, take out medium packetization types and packaging time length according to the information of media negotiation in the signaling, the Qos control module finds corresponding counter with this packetization types and packaging time length as keyword, and counter is added 1.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
