Table 2

3GPP LTE-A standardized QCI and priorities.

QCI	Priority	Resource type	Delay budget	Example services
1	2	GBR	100 ms	Conversational voice
2	4	GBR	150 ms	Conversational video (live streaming)
3	3	GBR	50 ms	Real-time gaming
4	5	GBR	300 ms	Nonconversational video (buffered streaming)
5	1	Non-GBR	100 ms	IMS signaling
6	6	Non-GBR	300 ms	Video (buffered streaming), TCP-based (e.g., www, e-mail, chat, FTP, P2P file sharing, progressive video, etc.)
7	7	Non-GBR	100 ms	Voice, video, interactive gaming
8	8	Non-GBR	300 ms	Video (buffered streaming), TCP-based (e.g., www, e-mail, chat, FTP, P2P file sharing, progressive video, etc.)
9	9	Non-GBR	300 ms	Video (buffered streaming), TCP-based (e.g., www, e-mail, chat, FTP, P2P file sharing, progressive video, etc.)
