Below, respectively to when code resource space idle up in TD existing network, moderate load and high load capacity time these three kinds of situations under the specific works situation of embodiment of the present invention dispatching device analyze.
1, in TD existing network, up code resource is idle
When PS business and CS service concurrence occur, first, the relation of up code resource utilization and the first threshold value n1 in now TD existing network is judged by the monitoring module 21 in dispatching device;
Here, when up code resource utilization is less than or equal to the first threshold value n1, represent that the up code resource utilization in TD existing network is lower, namely up code resource is in idle condition, now, can send underload early warning signal.
Particularly, when up code resource utilization is less than or equal to the first threshold value n1, then show that the up code resource utilization in now network is lower, now, do not need to carry out compression process to CS business and PS business, the coded system of the AMR12.2k of flank speed during CS business also can adopt AMR to encode.
In the voice and packet data concurrent service that scheduler module 23 in dispatching device can detect according to the detection module 22 in dispatching device, the size of PS business data packet judges voice and packet data concurrent service to be dispatched to R4 carrier wave or mixed carrier.
Here, when being only configured with R4 carrier wave in community, still adopt existing DPCH to carry voice and packet data concurrent service; When being configured with mixed carrier in community, adopt mixed carrier carrying voice and packet data concurrent service.Because mixed carrier not only has the DPCH resource of each two time slots of uplink and downlink, have the HS-PDSCH time slot for transmitting high speed data, so be very applicable to voice and packet data concurrent service demand, when being configured with mixed carrier in system, efficiency of transmission is higher simultaneously.Therefore, the configuration of R4 carrier wave should be adjusted to mixed carrier configuration by system, and this adjustment non-invention embodiment emphasis set forth, no longer launches.
The size of the PS business data packet that scheduler module 23 can detect according to detection module 22 judges whether compress the PS business in voice and packet data concurrent service when adopting mixed carrier carrying voice and packet data concurrent service.
Here, when mixed carrier carrying voice and packet data concurrent service, in mixed carrier, the HS-PDXCH of TS3 time slot and TS4 time slot can support the PS business of large discharge.Simultaneously, because up code resource utilization is lower, in order to promote Consumer's Experience better, can consider to adopt mixed mode, namely at up direction, CS business and PS business take different code channel resources respectively, at down direction, adopt the HS-PDSCH slot transmission PS business in mixed carrier and DPCH slot transmission CS business.Fig. 3 is the schematic diagram of embodiment of the present invention mixed mode carrying voice and packet data concurrent service, and as shown in Figure 3, at up direction, CS business can take the code channel resource of TS1, and PS business can take the code channel resource of TS2; At down direction, utilize HS-PDSCH slot transmission PS business, utilize DPCH slot transmission CS business.
One section of code of the code channel method of salary distribution in composite mode is as follows:
Above-mentioned code shows when carrying voice and packet data concurrent service, and by DPCH slot transmission CS business, HS-PDSCH slot transmission PS business, does not repeat them here code related content.
When adopting mixed mode transmissions voice and packet data concurrent service, the peak rate of eating dishes without rice or wine of the mono-time slot of HS-PDSCH can reach 560kbps, be significantly higher than the 128kpbs of R4 carrier wave, downloading rate is promoted to 1120kpbs by 384kpbs, downloading rate can promote 2.9 times, in addition, adopt mixed mode not only to improve the concurrent speed of PS business, the perception of user also can be made better.
2, up code resource moderate load in TD existing network
If the monitoring module in dispatching device 21 judges that now up code resource utilization is greater than the first threshold value n1 in TD existing network, but when being less than the second threshold value n2, namely represent that the up code resource in now TD existing network is in moderate load condition, the scheduler module 23 in dispatching device saves up code resource by the up of compression PS business with channel resource.
At present, for the situation of R4 carriers carry sending service, because minimum bearing resource is the code channel of 4 SF=16, can not compress further.
In the embodiment of the present invention, if when detection module 22 detects the flow of PS business lower than flow threshold, namely, when in voice and packet data concurrent service, the size of PS business data packet is parcel, scheduler module 23 judges that carrying out frame to the PS business in the voice and packet data concurrent service carried by mixed carrier divides compression.Here, for the situation adopting mixed carrier carrying voice and packet data concurrent service, the reconfigurable RAB of system (RAB, Radio Access Bearer), makes PS business independently enter two times of frames and divides multiplexing status.Fig. 4 is that embodiment of the present invention up direction CS business and PS traffic frame divide multiplexing schematic diagram, owing to being that the PS business of low discharge is carried out frame and divided multiplexing, do not affect uplink traffic transmission, now, voice and packet data concurrent service downloading rate still can reach more than 200kb/s, still can ensure user awareness, simultaneously, uplink code channel resource is only equivalent to take 3 SF=16, and ascending resource utilization ratio can promote 25%.
3, up code resource high load capacity in TD existing network
If the monitoring module in dispatching device 21 judges that now up code resource utilization has been more than or equal to the second threshold value n2 in TD existing network, then illustrate that the up code resource in now TD existing network is in higher load condition, now, the scheduler module 23 in dispatching device will enable compact model to voice and packet data concurrent service.
Here, the second threshold value n2 can set according to actual needs, such as, can be set to 80%.
Below, compact model is all adopted to analyze as follows to CS business and PS business.
(1) CS business is compressed:
In existing network, CS business adopts the coded system of AMR12.2k.AMR coding has 8 kinds of speed, comprising: 12.2kbit/s, 10.2kbit/s, 7.95kbit/s, 7.4kbit/s, 6.7kbit/s, 5.9kbit/s, 5.15kbit/s, 4.75kbit/s.During high load capacity, such as busy, just likely adopts lower AMR speed to provide larger capacity while ensureing lower slightly speech quality.Fig. 5 is the schematic diagram of MOS value corresponding to different coding mode, and as can be seen from Figure 5, in all cases, the MOS value of AMR-HR is all better than FR, only lower than EFR; And CS business adopts the coded system of AMR4.75k, just can ensure the MOS value of service needed, not affect Consumer's Experience.
(2) PS business is compressed:
In existing business model, accounting lower than the PS business (i.e. low discharge PS business) of flow threshold is increasing, such as QQ is online, heartbeat message, positional information etc., the up-downgoing flow of this type of low discharge PS business is all very little, is generally all less than 8kbps, described low discharge PS business can be transmitted with lower resources mode together with CS mix of traffic completely.
When the monitoring module 21 in dispatching device detects that system is in high load capacity, voice and packet data concurrent service is compressed: preferentially reconfigured by the voice and packet data concurrent service of low discharge PS business and CS business and enter compact model, CS business and the up-downgoing of PS business are transmitted in 2 SF=16 in upper and lower time slot.
In high load capacity situation, for voice and packet data concurrent service, due to PS service downloading relative insensitivity, now system need access more user and business, scheduler module 23 is after compressing low discharge PS business, if when system loading is still very high, the PS business more except low discharge PS business is also dispatched compact model.
In high load capacity situation, be no matter adopt traditional R4 carrier wave or mixed carrier is to carry voice and packet data concurrent service, scheduler module 23 all will be compressed PS business.Particularly, according to the PS service traffics size of carrying, PS business can be compressed to 0-8K; And for CS business, then can select the one in the coded systems such as AMR10.2kbit/s, 7.95kbit/s, 7.4kbit/s, 6.7kbit/s, 5.9kbit/s, 5.15kbit/s, 4.75kbit/s, scheduler module 23 selects the coded system of CS business according to the size after the compression of PS business, thus ensures that PS business and CS business can share the resource of two code channels.
The schematic diagram that Fig. 6 compresses voice and packet data concurrent service when being and adopting R4 carriers carry voice and packet data concurrent service in high load capacity situation, as can be seen from Figure 6, for R4 carrier wave, after compression is adopted to voice and packet data concurrent service, the resource taking two code channels can be reduced, ascending resource utilization ratio can promote 50%, when up code resource high load capacity, effectively improves the performance of system.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
