回复 jianglibing 的帖子
仔细查了下,确实是有的。我都没有注意到。惭愧。
好处正如你说的那样,可以给用户带来更好的业务体验。
更多的细节和背景我也不了解,抱歉。
这里只补充下,R10做了下更新。
The following procedures shall be performed in the MS when the RRC layer indicate to higher layer that a RAB has been released and the RAB release was not initiated due to a PDP Context Deactivation Procedure:
- For a PDP context using background or interactive traffic class, the PDP context is be preserved with no modifications.
- For a PDP context using streaming or conversational traffic class and if the TFT include packet filter(s) set by the MS, the PDP context may be is preserved, but the maximum bit rate is downgraded to 0 kbit/s (for both uplink and downlink). If the TFT only include packet filter(s) set by the network or if the TFT include packet filter(s) set by the MS and the PDP context was not preserved, the PDP context is locally deactivated in the MS.
- At this point or at a later stage (for preserved PDP contexts), the MS may start a PDP Context Deactivation procedure or PDP Context Modification procedure. The MS shall use the PDP context modification procedure to re-activate the PDP context and to re-establish the RAB.
