Technical field
The present invention relates to the communication technology, the adaptive multi-rate grouping voice that relates in particular in the communications field is compiled AMR VoIP pattern adjustment technology.
Background technology
Traditional telephone network is with the circuit exchange mode transferring voice, and desired transmission broadband is 64kbit/s.And because telephone service always is the strictest business of various countries' control, and international long-distance telephone expense in various countries' exists serious disequilibrium, the international long-distance telephone business is all monopolized in a lot of countries, so, along with the development of internet Internet, realize that on Internet voice call becomes a kind of trend.
Development along with technology, Internet and existing public switched telephone network (PSTN) (PSTN have been realized, PublicSwitched Telephone Network) combination, make IP (Internet Protocol) phone develop into from originally PC (Personal Computer) to PC PC to PC, PC to phone, phone is to multiple business forms such as phones, and to the transition of IP transmitting multimedia service.But come what may, the IP phone bearer network is Internet, or follows the private network or the Internet of ICP/IP protocol.
As at universal mobile telecommunications system (UMTS, Universal Mobile TelecommunicationsSystem) in, UMTS is the 3-G (Generation Three mobile communication system) that adopts WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA) inserts) air interface technologies.
As shown in Figure 1, the UMTS system comprises RAN (Radio Access Network, wireless access network) and CN (Core Network, core net).Wherein RAN is used to handle all and wireless relevant process, and all voice calls are connected with data in the CN processing UMTS system, and the exchange of realization and external network and routing function.CN is from being divided into CS (Circuit Switched Domain in logic, circuit commutative field) and PS (Packet Switched Domain, packet-switched domain), CS generally comprises MSC (MobileSwitching Center, mobile switching centre)/VLR (Visitor Location Register, VLR Visitor Location Register), GMSC (Gateway Mobile Switching Center, Gateway Mobile Switching Center), gsmSSF, PS generally comprises SGSN (Serving GPRS Support Node, Serving GPRS Support Node), GGSN (Gateway GPRS Support Node, Gateway GPRS Support Node); CS mainly handles speech businesses such as relevant phone, voice, and PS then handles relevant Packet data service.UTRAN (UMTSTerritorial Radio Access Network UMTS, land radio access web), CN and UE (UserEquipment, user terminal) constituted whole UMTS system together, the UMTS system connects external network, for example: PSTN and the Internet.
Above-mentioned land radio access web UTRAN, its network configuration block diagram as shown in Figure 2, comprise at least one RNS (Radio Network Subsystem, RNS), a RNS is by a RNC (Radio Network Controller, radio network controller) and at least one NodeB (base station) form, NodeB can cover at least one sub-district CELL.
NodeB is the base station (being radio receiving-transmitting unit) of WCDMA system, comprises radio receiving-transmitting unit and Base-Band Processing parts.By the Iub interface and the RNC interconnection of standard, mainly finish the processing of Uu interface physical layer protocol, major function is spread spectrum, modulation, chnnel coding and despreading, demodulation, channel-decoding, also comprises the functions such as mutual conversion of baseband signal and radiofrequency signal.
RNC is a radio network controller, is used to control the Radio Resource of UTRAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.
Iub interface between RNC and NodeB generally uses a plurality of AAL2PVC to carry the data of UE, and these data comprise CS voice, the PS data of UE.
Carrying out voice communication by Internet is a very complicated system engineering, and related technology is also more, and wherein the most basic technology is packet voice (VoIP, a Voice over IP) technology.
VoIP is to be transmission platform with the IP packet switching network, sees through the speech sound signal of IP network transmission or the technology of image signal.Its basic principle is: by voice compression algorithm speech data is carried out compressed encoding and handle, then these speech datas are packed by related protocols such as IP, through IP network data packet transmission is arrived reception ground, again these VoPs are stringed together, after the decoding decompression processing, revert to original voice signal, thereby reach the purpose that transmits voice by IP network.IP telephony system becomes the analog signal conversion of plain old telephone computer can link the IP packet that the internet transmits, and also the IP packet of receiving is converted to the analog electrical signal of sound simultaneously.Handle through the conversion of IP telephony system and compression, each plain old telephone transmission rate takies 8～11Kbit/s bandwidth approximately, and therefore when using transmission rate as the bandwidth of 64kbit/s equally with common telecommunications network, the IP phone number is original 5～8 times.
At present at Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) in the system, voice adopt adaptive multi-rate (AMR, Adaptive Multi-Rate) compressed encoding, are converted to the IP packet then and transmit on IP network.AMR VoIP coding is a kind of adaptive coding method, can produce 8 kinds of different patterns, each pattern is corresponding to a kind of speed: 12.2,10.2,7.95,7.4,6.7,5.9,5.15 and 4.75kbit/s, and also be that different patterns can provide different voice qualities.Smaller or equal under 1% the condition, pattern is high more at bLock error rate (BLER, Block error rate), and the voice quality that provides is high more, but the transmission channel bandwidth resource (comprising load resource and Iub resource) that takies is also many more.
The VoIP operation flow can carried out RAB (RAB, Radio AccessBearer) when setting up as shown in Figure 3, at first sends the RAB assignment request message by CN to UTRAN, and request UTRAN sets up RAB.The IMS signaling bear is set up in the RAB assignment, and call subscriber terminal and called user terminal pass through separately UTRAN, PS territory then, carry out session control protocol SIP/SDP session according to the IMS signaling channel, mainly is to consult code rate etc.; Be to set up service bearer at last, corresponding service quality (the QoS of core net CN meeting assignment, Quality of Service) parameter, radio network controller (RNC, Radio NetworkController) according to the QoS of different mode, be VoIP traffic assignments corresponding bandwidth resource, both sides UE carries out multimedia service RTP (Real-time Transport Protocol)/real time business control protocol RTCP session.
Real-time Transport Protocol is based on user terminal data newspaper agreement (UDP, User Datagram Protocol)/ carrying that IP provides, as shown in Figure 4, IP/UDP/RTP message structure schematic diagram for voice-bearer stream among the WDMA, always have the head of 60 bytes (IPv6) or 40 bytes (IPv4), wherein 40 bytes of IP head (IPv6) or 20 bytes (IPv4), 8 on UDP head and 12 bytes of RTP head.
In Fig. 4, corresponding 3G PS terminal, RTP PAYLOAD form is: payload header|tableof contents|speech data, wherein payload header issues the coding mode request CMR of local terminal UE for opposite end UE, in the prior art, local terminal can only be selected the pattern smaller or equal to CMR; The AMR speech frame of speech data for transmitting, for 3G PS terminal, each RTP bag only encapsulates a speech frame in the prior art; Table of contents mainly comprises the pattern information and the frame quality indication (CQI) information of this speech frame.
In existing data transmission procedure, RNC carries out transparent transmission to the RTP bag of speech business, promptly only RTP/UDP/IP is wrapped (or the RTP/UDP/IP after the compression wraps) and wraps in as data and eat dishes without rice or wine to transmit, and do not require current pattern information.But in communication process, because changes such as transmission environment and position and may cause channel quality decline, or work as system load, Iub resource near saturated, if at this time still adopt the height mode transmission to impact to voice quality, but also can add the congested of heavy duty and Iub resource, cause the professional impaired of certain customers' terminal, influence QoS.
