Overview
2.1 Background
Video services on UMTS networks are an important concern for mainstream operators because they are closely related to user experience. Based on video service characteristics, the Video Accelerator Phase 1 feature optimizes video services at all protocol layers to improve video service experience.
2.2 Introduction
With the RAN service awareness function, this feature reduces the initial video buffering delay, shortens the pause duration proportion, and increases the video download rate by optimizing video services at all protocol layers on light- and medium-load networks, thereby improving video service experience.
2.3 Benefits
This feature provides differentiated services to improve video service experience in light- or medium-load scenarios. Table 2-1 lists the improved video service counters.
Table 2-1 Improved video service counters Service Type Counter
HTTP video Initial video buffering delay and video pause duration proportion

NOTE
When a cell is in the light- or medium-load status, this feature can decrease the initial HTTP video buffering delay by 5% to 15%, reduce the HTTP video pause duration proportion by 5% to 20%, and increase the HTTPS video download rate by 5% to 15%.
NOTE
The feature gains will decrease if the following operations are performed before this feature is enabled: l WRFD-180106 User Experience Improvement for Lightly Loaded Cells is enabled.
l The Min. Times of HS-DSCH Data Packet Scheduling parameter in the SET UDPUCFGDATA command is set to D10.

Technical Description
A cell is in the light- or medium-load status if all the following conditions are met. l Non-HSDPA power load ≤ 40%
VS.MeanTCP.NonHS(BSC6900,BSC6910) (W)/Configured PA Capacity (W) ×
100% ≤ 40% where,
VS.MeanTCP.NonHS(BSC6900,BSC6910) (W) =
10^(VS.MeanTCP.NonHS(BSC6900,BSC6910)/10 – 3)
Configured PA Capacity (W) = 10^(MaxTxPower(BSC6900,BSC6910)/10 – 3)
NOTE
W is the unit for counter values.
l Uplink power load ≤ 75%: VS.meanRTWP(BSC6900,BSC6910) –
VS.BackGroundNoise.Mean(BSC6900,BSC6910) ≤ 6 dB

3.1 Definition
Video service refers to a human-computer interaction process in which streaming media information is exchanged between a browser or an application program and the server through the HTTP or HTTPS protocol.
HTTP Video Services
The following counters are used to evaluate HTTP video services.
1. Initial video buffering delay: duration from point A or A' to point C as shown in Figure 3-1.
During a video service process, at point A (the DNS query process is preferentially initiated) or point A' (the DNS query process is not initiated), the RNC receives the first video data packet from a UE, indicating that a video service starts.
At point C, the amount of the downloaded data reaches the threshold for video playing, indicating that initial video buffering is complete and video playing starts.
2. Video pause duration proportion: proportion of the video pause duration to the video playable duration. During video playing, if the data rate on a network is less than the video code rate, the cache in a UE's video player is cleared and video buffering re-starts. Video playing pauses and will not resume until the conditions for video playing are met. When the RNC receives the TCP ACK message of the last HTTP data packet at point D, video data download is complete. When the TCP connection established for the video service is released at point E, the video service is complete.
Figure 3-1 HTTP video service process
HTTPS Video Services
Being different from HTTP video services, HTTPS video services require encryption for data packets and use the video download rate to evaluate service experience. As shown in Figure
3-2, the video download rate indicates the average download rate from point A (the RNC receives the first application data packet) to point B (the RNC receives the TCP ACK message of the last application data packet).
3.2 Principles
Figure 3-3 shows the principle of the Video Accelerator Phase 1 feature. After identifying video services through service awareness, the RNC performs the following operations: l TCP proxy optimization enhancement
l MAC-d scheduling optimization l Permanent CELL_DCH state l HSUPA bearer optimization
l Compressed mode parameter optimization l Serving cell change optimization
Then the RNC sends a video service optimization instruction to the NodeB through the private FP frames added over the Iub interface. After receiving the instruction, the NodeB performs HSDPA blind sending and compressed mode scheduling optimization for video services. After detecting that video services are complete, the RNC stops performing the preceding optimization operations and instructs the NodeB to terminate optimization for video users.
Figure 3-3 Principle of the Video Accelerator Phase 1 feature
TCP Proxy Optimization Enhancement
l TCP proxy full-rate sending
After identifying video services, the RNC does not perform TCP congestion control but matches the TCP congestion window with the UE receive window in full-rate sending mode when video service scheduling is not limited over the air interface. This helps improve the TCP proxy performance.
l TCP proxy cache mechanism optimization
After identifying video services, the RNC still supports TCP proxy when the size of the UE receive window is greater than 512 kbytes or when TCP proxy yields no gains. This ensures that the air-interface data rate for video services will not be restricted due to the limited TCP rate.
MAC-d Scheduling Optimization
After identifying video services, the RNC schedules data packets in the HS-DSCH ten times every 10s to ensure timely sending of video service data and reduce the initial video buffering delay.
Permanent CELL_DCH State
After identifying video services, the RNC keeps video users in the CELL_DCH state to improve the video download rate until video services are complete when all of the following conditions are met:
l The load of CELL_DCH user quantity is lower than the value of
VideoAccDchUserLoadState(BSC6900,BSC6910).
l The actual uplink cell load is lower than the value of
VideoAccULActualLoadState(BSC6900,BSC6910).
l The downlink power load is lower than the value of
VideoAccDLPwrLoadState(BSC6900,BSC6910).
HSUPA Bearer Optimization
When the uplink cell load and admitted CE resources are not limited, the RNC enables uplink video services to be carried over the HSUPA with a TTI of 2 ms so that UEs can quickly reply with the TCP ACK message. This accelerates the speed of delivering downlink video service data and improves video service experience.
Serving Cell Change Optimization
After identifying video services, the RNC shortens the activation duration of serving cell change to accelerate serving cell change, thereby reducing the duration that video users camp on cells with poor signal quality and improving service experience.
Compressed Mode Parameter Optimization
The RNC uses independent compressed mode measurement time by setting the
VideoUECovMeasTimer(BSC6900,BSC6910) and
VideoUENonCovMeasTimer(BSC6900,BSC6910) parameters to reduce the duration for
coverage-based and non-coverage compression mode measurement and improve video service experience.
HSDPA Blind Sending
After identifying video services, the RNC sends the NodeB an HSDPA blind sending
instruction through private FP frames added over the Iub interface to support blind sending in the scenario where the uplink signal quality is not sound and the CQI is 0 within consecutive 200 TTIs. This improves video service experience of cell edger users.
Compressed Mode Scheduling Optimization
After identifying video services, the RNC sends the NodeB an HSDPA blind sending instruction through private FP frames added over the Iub interface to support forcible scheduling in uplink compressed mode. This improves video service experience of cell edger users.
