QCI bernilai 1 sampai 9 dengan masing-masing prioritas, prioritas yang lebih tinggi diutamakan dalam alokasi traffic bearer. Priority 0.5 adalah level yang paling tinggi. Jika congestion terjadi maka priority yang lebih rendah yang traffiknya akan dihilangkan terlebih dahulu.
QCI-65, QCI-66, QCI-69 and QCI-70 diperkenalkan dalam 3GPP TS 23.203 Rel-12
QCI | Resource Type | Priority | Packet Delay Budget | Packet Error Loss | Example Services |
---|---|---|---|---|---|
1 | GBR | 2 | 100ms | 10−2 | Conversational Voice |
2 | GBR | 4 | 150ms | 10−3 | Conversational Video |
3 | GBR | 3 | 50ms | 10−3 | Real Time Gaming |
4 | GBR | 5 | 300ms | 10−6 | Non-Conversational Video (Buffered Streaming) |
65 | GBR | 0.7 | 75ms | 10−2 | Mission Critical user plane Push To Talk voice (e.g., MCPTT) |
66 | GBR | 2 | 100ms | 10−2 | Non-Mission-Critical user plane Push To Talk voice |
5 | non-GBR | 1 | 100ms | 10−6 | IMS Signalling |
6 | non-GBR | 6 | 300ms | 10−6 | Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like) |
7 | non-GBR | 7 | 100ms | 10−3 | Voice, Video (Live Streaming), Interactive Gaming |
8 | non-GBR | 8 | 300ms | 10−6 | Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like) |
9 | non-GBR | 9 | 300ms | 10−6 | Video (Buffered Streaming) TCP-Based (for example, www, email, chat, ftp, p2p and the like) |
69 | non-GBR | 0.5 | 60ms | 10−6 | Mission Critical delay sensitive signalling (e.g., MC-PTT signalling) |
70 | non-GBR | 5.5 | 200ms | 10−6 | Mission Critical Data (e.g. example services are the same as QCI 6/8/9) |
catatan : QCI dengan CQI berbeda, CQI adalah Channel Quality Indicator yang bernilai dari 1 sampai 15 yang merepresentasikan modulasi yang didapatkan oleh UE (user equipment) seperti QPSK, 16 QAM, 64 QAM.
