" Idle state " and " connected state " are introduced first, term as " Idle state " and " connected state " is from RRC
For layer angle.In simple terms, when UE is after some cell completes resident, so that it may claim the UE to enter " idle
State ".If the UE is subsequent and random access procedure is completed, the UE can be claimed to enter " connected state ".It is either empty
Not busy state or connected state have checked whether if UE will monitor always downlink PDCCH subframe without DRX mechanism from clothes
The information for cell of being engaged in.Most of time, UE and network are not data interactions, if this when of UE also removes lasting prison
Listen PDCCH subframe, it is clear that be very power-consuming.Thus, under the premise of guaranteeing that data can be transmitted effectively, it is necessary to design a kind of section
The mechanism of UE electricity is saved, this mechanism is known as discontinuous reception (DRX).DRX mechanism can allow UE periodically sometimes
Into sleep state, when not going to monitor PDCCH subframe, and need to monitor, then waken up from sleep state, it thus can be with
So that UE is achieved the purpose that power saving, does so and have a certain impact to the time delay of data transmission.And CDRX is the DRX machine under connected state
System.
It will appear the poor problem of voice quality in the region of certain signal covering differences after commercial for VoLTE, 3GPP is proposed
Delay Budget Report mechanism is to optimize the VoLTE end-to-end time delay under weak coverage condition.Delay Budget
The working model of Report mechanism is as shown in Fig. 2, VoLTE call is established in the carrying of QCI=1, according to the design of 3GPP,
It is 100ms that QCI=1, which carries corresponding end-to-end time delay Packet Delay budget (PDB, Packet Delay Budget), also
Be say VoLTE call both ends end-to-end time delay should not be more than 100ms, if it exceeds after will receiving end discarding.
And VoLTE speech quality difference generally poor is caused by the radio signal quality of one end.As shown in Fig. 2, UE1 is in nothing
The preferable region of line channel quality, since quality of wireless channel is deteriorated, number of retransmissions increases UE2, and eNB to UE2 time delay is caused to increase
Greatly；The VoLTE end-to-end time delay that the end UE1 measures increases.At this point, UE1 radio signal quality is preferable, but when VoLTE is end-to-end
Prolong it is larger, can to eNB1 send Delay Budget Report message pass through CDRX Cycle Adjustment field signals
ENB adjustment oneself CDRX period of reduction is arranged, and so as to shorten the transmission time between UE1 to eNB1, and then shortens UE1 and UE2
Between VoLTE end-to-end time delay, achieve the purpose that promoted VoLTE speech quality.
Wherein, it is provided according to RFC3550, VoLTE end-to-end time delay can be calculated by the simplification of the winding time delay of RTP packet
It arrives, as shown in Figure 3.
Wherein, the time that SRn is issued for RTP packet transmitting terminal can be calculated by LSR；After receiving end receives SRn, warp
The processing delay of DLSR is crossed, sends RR receipt to transmitting terminal；Transmitting terminal receives RR receipt in the A moment；The winding time delay of RTP packet
RTT=(time A-time LSR-DLSR).Approximate available VoLTE end-to-end time delay is (time A-time LSR-
DLSR)/2。
Wherein, to calculate time delay method of eating dishes without rice or wine in terminal side as follows:
Upper layer PDCP packet to be sent enters that terminal logic channel queue etc. is to be sent, and terminal records the PDCP packet bottom of to
Layer sends the time 1 of indication, and after which sends successfully, the PDCP packet for recording bottom-up layer transmission, which is sent, successfully to be referred to
Show the primitive time 2；Time delay of eating dishes without rice or wine RTT=(time time 2- 1).Approximate available time delay of eating dishes without rice or wine is (time time 2- 1)/2.
For above-mentioned Delay Budget Report mechanism, UE is poor in VoLTE speech quality, but wireless signal matter
CDRX period modulation mechanism is triggered when measuring relatively good, is sent Delay Budget Report message and is suggested that eNB adjusts oneself
+/- Xms is arranged in the CDRX period.The time delay of eating dishes without rice or wine of comparison end-to-end time delay and both-end in through the embodiment of the present invention, it can be deduced that
