As shown in Fig. 2, the embodiment of the present invention provides a kind of method of bearer circuit domain voice service, this method is used for downlink Direction, specific as follows:

Step 201, first network equipment receives at least one first language that second network equipment is sent by first interface Sound frame, wherein first network equipment be the first standard the network equipment, second network equipment be the second standard the network equipment or Person is the network equipment of compatible first standard and the second standard.

For example, first network equipment can be the eNB or the AP in WLAN of LTE network.Second network equipment can be It is responsible for the SRC coordinated to multiple standard resources or second network equipment is the RNC of UMTS or the BSC of GSM network.

Wherein, the interface that first interface connects between first network equipment and second network equipment.For example, first interface For Iu interface.In the present embodiment, the first speech frame can be AMR speech frame.Certainly, the present embodiment does not limit the kind of speech frame Class.

At least one first speech frame is that second network equipment adds time letter at least one received second speech frame Cease and transmit Sequence Number and the speech frame that obtains, wherein temporal information is that second network equipment receives at least one second language The time of sound frame transmits Sequence Number and sends what sequencing obtained according at least one the first speech frame for second network equipment Sequence number, at least one second speech frame are the voice that second network equipment receives that the moving exchanging center MSC of circuit domain is sent Frame.

Step 202, at least one first speech frame is sent to UE by second interface by first network equipment.

Wherein, first standard of the second interface between first network equipment and UE is eated dishes without rice or wine.First standard is eated dishes without rice or wine can be with It eats dishes without rice or wine for LTE.

After at least one first speech frame is sent to UE by first network equipment, UE is by least one the first speech frame Key dithering obtains at least one the 6th speech frame, to carry out normal voice transfer.

In the present embodiment, UE can be bimodulus UE.For example, bimodulus UE refers to while having UMTS and LTE protocol stack Terminal.

FDDI sublayer protocol of eating dishes without rice or wine (Media Access Control, MAC) scheduling due to LTE and first The factors such as layer (Layer one, L1) re-transmission, in fact it could happen that speech frame cannot uniformly reach receiving end, tremble to generate time delay It is dynamic, cause the normal sequence of speech frame to be disturbed during transmission, be referred to as eating dishes without rice or wine to shake, wherein MAC layer is responsible for The scheduling of data packet, it is determined whether need to send data packet；L1 indicates open system interconnection (Open System Interconnect, OSI) in physical layer, be responsible for the transmission of specific data.Therefore, it in order to obtain smooth voice communication, needs It will be to received speech frame Key dithering, to obtain the speech frame of correct sequence.

Explanation is needed further exist for, second network equipment adds temporal information and transmission at least one second speech frame The mode of sequence number includes, but are not limited to, the following ways:

Second network equipment can pass through the grouping in second network equipment after receiving at least one second speech frame Data convergence protocol (Packet Data Convergence Protocol, PDCP) layer is that the addition of each second speech frame receives To the time (i.e. temporal information) of corresponding second speech frame, and each second speech frame is delivered to wireless spread-spectrum technology (Radio Link Control, RLC) layer, in rlc layer, RNC adds transmitting Sequence Number for corresponding second speech frame.By temporal information and hair It send sequence number addition on corresponding second speech frame, obtains at least one first speech frame.Specifically, second network equipment It, can be by the Connection Frame Number of eating dishes without rice or wine of second network equipment of corresponding second speech frame after receiving each second speech frame 5 bits are used to carry temporal information afterwards, and the temporal information is placed in the PDCP of the second speech frame, specifically, when by this Between the information PDCP that is placed on the second speech frame header structure in.PDCP is a wireless transmission protocol stack in UMTS, for setting Set the temporal information of speech frame.Wherein, temporal information can be indicated with CFN.In addition, transmitting Sequence Number can be the serial number of RLC. Transmitting Sequence Number can be indicated with SN.

For example, having sent multiple continuous AMR speech frames to RNC by Iu interface in MSC, RNC is multiple continuous in reception The temporal information of AMR speech frame be respectively as follows: CFN=0；CFN=1；CFN=9, CFN=10, CFN=11.RNC is at five It is respectively set in the PDCP header structure of AMR speech frame are as follows: CFN=0, CFN=1, CFN=9, CFN=10, CFN=11.Due to This five AMR speech frames are continuously to be sent to rlc layer, therefore rlc layer transmits Sequence Number for this five AMR speech frame additions When, it is respectively as follows: SN=0, SN=1, SN=2, SN=3, SN=4.

It should be noted that the corresponding temporal information of AMR speech frame and corresponding transmit Sequence Number can be one-to-one correspondence Relationship, as first AMR speech frame add SN=0, CFN=0；SN=1, CFN=are added for second AMR speech frame 1；SN=2, CFN=9 are added for third AMR speech frame；SN=3, CFN=10 are added for the 4th AMR speech frame；It is the 5th A AMR speech frame adds SN=4, CFN=11.

Explanation is needed further exist for, the mode that UE carries out Key dithering at least one first speech frame includes but is not limited to Following manner:

The access layer (Access Storey, AS) of UE is according to the docking that transmits Sequence Number carried on each first speech frame The sequence for all first speech frames progress sequencing received, each first after being then correctly ordered according still further to temporal information Mode is sent to the Non-Access Stratum (Not Access Storey, NAS) of UE to speech frame in a continuous manner or discontinuously.Continuously Mode is the time in temporal information to be continuously, such as CFN=0, CFN=1, CFN=2, CFN=3, CFN=4；Discontinuous side Formula be the time in temporal information be it is discrete, such as CFN=0, CFN=1, CFN=9, CFN=10, CFN=11.According to The example above explanation, then each first speech frame after the AS of UE will be correctly ordered are sent to the NAS of UE in a discontinuous manner.

Specifically, when at least one first speech frame (five AMR speech frames) does not have during LTE air interface transmission When packet loss, bimodulus UE receives first AMR speech frame in order, third AMR speech frame, the 4th AMR speech frame, and second A AMR speech frame, the 5th AMR speech frame, bimodulus UE is according to the SN of this five AMR speech frames to this five AMR speech frame weights It is newly ranked up, obtains first AMR speech frame, second AMR speech frame, third AMR speech frame, the 4th AMR voice Frame, the 5th AMR speech frame.Due to the generation of AMR speech frame be it is discontinuous, centre may have quiet frame (quiet frame Refer to during communication, the specific human voices frame formed due to there is free time between voice, without essence in quiet frame Voice content).Bimodulus UE receives first AMR speech frame, second AMR speech frame, third AMR speech frame, and the 4th A AMR speech frame after the 5th AMR speech frame, is sent to the first net in second network equipment according to this five AMR speech frames The temporal information of network equipment, to determine that the AS of bimodulus UE sends the AMR speech frame received in a manner of discontinuously sending The interval time when NAS of bimodulus UE between each AMR speech frame.As transmitting terminal uniformly sends an AMR language every 20ms Sound frame, the CFN at least one first speech frame are the connection numbers that each AMR speech frame is received for receiving end, first It is CFN=0 that AMR speech frame, which adds temporal information, and second AMR speech frame addition temporal information is CFN=1；Third AMR It is CFN=9 that speech frame, which adds temporal information,；4th AMR speech frame addition temporal information is CFN=10；5th AMR language It is CFN=11 that sound frame, which adds temporal information, so 8 differed between second AMR speech frame and third AMR speech frame Time difference between CFN, i.e. second AMR speech frame and third AMR speech frame is 160ms.It specifically can refer to shown in Fig. 3 First AMR speech frame, second AMR speech frame, third AMR speech frame, the 4th AMR speech frame and the 5th AMR The structure chart for being sent to NAS of speech frame.

It is double when during LTE air interface transmission packet loss occurs at least one first speech frame (five AMR speech frames) Mould UE only receives first AMR speech frame, the 4th AMR speech frame and the 5th AMR speech frame.According to these three AMR voices The SN of frame is ranked up first AMR speech frame, the 4th AMR speech frame and the 5th AMR speech frame.Due to AMR voice The generation of frame be it is discontinuous, centre may have quiet frame.First AMR speech frame is received in bimodulus UE, the 4th AMR speech frame after the 5th AMR speech frame, needs to calculate first AMR speech frame, the 4th AMR speech frame and the 5th A AMR speech frame is sent to the temporal information of eNB in RNC, to determine that the AS of bimodulus UE will be received in a manner of discontinuously sending To AMR speech frame be sent to the NAS of bimodulus UE when each AMR speech frame between interval time.Such as first AMR language It is CFN=0 that sound frame, which adds temporal information, and the 4th AMR speech frame adds temporal information as CFN=10, therefore first AMR 10 CFN differed between speech frame and the 4th AMR speech frame, i.e. first AMR speech frame and the 4th AMR speech frame it Between time difference be 200ms.It specifically can refer to first AMR speech frame shown in Fig. 4, the 4th AMR speech frame and the 5th The structure chart for being sent to NAS of a AMR speech frame.
