The embodiments of the invention provide a kind of system of bearer circuit domain speech business, speech business can be completed not against IMS deployment, so as to reduce cost, and the data service being currently running in the lte networks is not interrupted, reduce the time delay that speech business is set up.As shown in Fig. 2 the method that the embodiment of the present invention provides a kind of speech business of bearer circuit domain, this method is used for down direction, its is specific as follows：

Step 201, first network equipment receives at least one first speech frame that second network equipment is sent by first interface, wherein, first network equipment be the first standard the network equipment, second network equipment be the network equipment of the second standard or be compatible first standard and the second standard the network equipment. For example, first network equipment can be the AP in the eNB or WLAN of LTE network.Second network equipment can be the UMTS RNC or BSC of GSM network to be responsible for the SRC coordinated to multiple standard resources, or second network equipment.

Wherein, first interface is the interface connected between first network equipment and second network equipment.For example, first interface is Iu interfaces.In the present embodiment, the first speech frame can be AMR speech frames.Certainly, the present embodiment does not limit the species of speech frame.

At least one first speech frame adds temporal information and the speech frame obtained that transmits Sequence Number for second network equipment at least one second speech frame of reception, wherein, temporal information is the time that second network equipment receives at least one the second speech frame, the sequence number that sequencing is obtained that sends transmitted Sequence Number for second network equipment according at least one the first speech frame, the speech frame that at least one second speech frame sends for the moving exchanging center MSC in the second network equipment receiving circuit domain.

Step 202, at least one first speech frame is sent to UE by first network equipment by second interface.Wherein, second interface is eated dishes without rice or wine for the first standard between first network equipment and UE.First standard eats dishes without rice or wine to eat dishes without rice or wine for LTE.

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

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

Due to LTE FDDI sublayer protocol of eating dishes without rice or wine（Media Access Control, MAC) dispatch and first layer（Layer one, L1) the factor such as re-transmission, receiving terminal can not uniformly be reached by being likely to occur speech frame, so as to produce delay variation, cause the normal sequence of speech frame to be disturbed during transmission, be referred to as shake of eating dishes without rice or wine, wherein, MAC layer is responsible for the scheduling of packet, it is determined whether need to send packet；L1 represents open system interconnection（Open System Interconnect, OSI) in physical layer, be responsible for specific data transfer.Therefore, in order to obtain unimpeded voice call, it is necessary to the speech frame Key dithering of reception, to obtain the speech frame of correct order. Explanation is needed further exist for, second network equipment adds temporal information and the mode including but not limited in the following manner transmitted Sequence Number at least one second speech frame：

Second network equipment can pass through the PDCP in second network equipment after at least one second speech frame is received（Packet Data Convergence Protocol, PDCP) layer be each second speech frame add receive correspondence the second speech frame time（That is temporal information）, 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 the second speech frame of correspondence.By temporal information and transmit Sequence Number addition on corresponding second speech frame, obtain at least one first speech frame.Specifically, second network equipment is after each second speech frame is received, rear 5 bits of the Connection Frame Number of eating dishes without rice or wine of second network equipment of the second speech frame of correspondence can be used for carrying temporal information, and be placed on the temporal information in the PDCP of the second speech frame, specifically, the temporal information is placed in the PDCP of the second speech frame header structure.PDCP is a wireless transmission protocol stack in UMTS, the temporal information for setting speech frame.Wherein, temporal information can be represented with CFN.Another sunset is foretold, and it can be RLC sequence number to transmit Sequence Number.Transmitting Sequence Number can be represented with SN.

For example, have sent multiple continuous AMR speech frames to RNC by Iu interfaces in MSC, RNC is respectively in the temporal information of the multiple continuous AMR speech frames of reception： CFN=0; CFN=1； CFN=9 , CFN=10, CFN=11.RNC is respectively set in the PDCP header structures of five AMR speech frames： CFN=0, CFN=1 , CFN=9, CFN=10, CFN=11.Due to this five AMR speech frames be it is continuous be sent to rlc layer, therefore rlc layer for this five AMR speech frames additions when transmitting Sequence Number, point another ' J is： SN=0, SN=1 , SN=2, SN=3 , SN=4.

It should be noted that the corresponding temporal information of AMR speech frames and corresponding transmit Sequence Number can be --- corresponding relation, as first AMR speech frame adds SN=0, CFN=0；For second AMR speech frames addition SN=1, CFN=1;For the 3rd AMR speech frames addition SN=2, CFN=9;For the 4th AMR speech frames addition SN=3, CFN=10;For the 5th AMR speech frames addition 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 in the following manner：

UE Access Layer (Access Storey, AS) according to transmitting Sequence Number of being carried on each first speech frame all first speech frames of reception are carried out with the sequence of sequencing, each first speech frame after being then correctly ordered according still further to temporal information is in a continuous manner or discontinuous mode is sent to UE Non-Access Stratum（ Not Access Storey , NAS ).Continuation mode be the time in temporal information be continuous, such as CFN=0, CFN=1, CFN=2, CFN=3, CFN=4;Discontinuous mode be the time in temporal information be discrete, such as CFN=0, CFN=1, CFN=9, CFN=10, CFN=11.Illustrate according to the example above, then each first speech frame after UE AS will be correctly ordered is sent to UE NAS in a discontinuous manner.

Specifically, when at least one the first speech frame（Five AMR speech frames）In Mei You Lost bags during LTE air interface transmissions, bimodulus UE receives first AMR speech frame in order, 3rd AMR speech frame, 4th AMR speech frame, second AMR speech frame, 5th AMR speech frame, bimodulus UE re-starts sequence according to the SN of this five AMR speech frames to this five AMR speech frames, obtain first AMR speech frame, second AMR speech frame, 3rd AMR speech frame, the 4th AMR speech frame, the 5th AMR speech frame.Because the generation of AMR speech frames is discontinuous, centre may have quiet frame（Quiet frame refers to during communication, due to occurring not having tangible voice content in specific human voices frame formed by free time, quiet frame between voice）.Bimodulus UE receives first AMR speech frame, second AMR speech frame, 3rd AMR speech frame, 4th AMR speech frame, after 5th AMR speech frame, the temporal information of first network equipment is sent in second network equipment according to this five AMR speech frames, interval time during determining that the AMR speech frames received are sent to bimodulus UE NAS by bimodulus UE AS in the way of discontinuously sending between each AMR speech frames.As transmitting terminal uniformly sends an AMR speech frame every 20ms, CFN at least one first speech frame is the connection numbering that each AMR speech frames are received for receiving terminal, first AMR speech frames addition temporal information is CFN=0, the second AMR speech frames addition time letter Cease for CFN=1;3rd AMR speech frames addition temporal information is CFN=9;4th AMR speech frames addition temporal information is CFN=10;5th AMR speech frames addition temporal information is CFN=11, so 8 CFN differed between second AMR speech frame and the 3rd AMR speech frame, i.e., the time difference between second AMR speech frame and the 3rd AMR speech frame is 160ms.The specific first AMR speech frame that can refer to shown in Fig. 3, second AMR speech frame, the 3rd AMR speech frame, the structure chart for being sent to NAS of the 4th AMR speech frame and the 5th AMR speech frame.
