Description
Technical field the present invention relates to electrical communication technology, the particularly method and apparatus that between dissimilar exchanging system networks, transmits of digital information, and the speech that especially relates to based on the Internet and mobile radio communication transmits.
The background technology traditional voice transmission is by circuit-switched network, and for example PSTN comes transmission of speech signals, and its desired transmission bandwidth is 64kbit/s.Nineteen sixties, unit such as U.S.'s Bell Laboratory proposed the notion and the theory of cellular system; The seventies semiconductor technology maturation, large scale integrated circuit, microprocessor and surface mount process are used widely, make and comprise the control system of cellular system complexity that travelling carriage control is achieved, thereby provide technical foundation for setting up cellular mobile communications networks.
The GSM cellular mobile communications networks that takes the lead in using is the revolution to traditional voice transmission.This communication system mainly is to be made up of exchanging network subsystem (NSS, Network Switching Subsystem), wireless base station subsystem (BSS, Base StationSubsystem) and travelling carriage (MS, Mobile Station) three parts.The networking that constitutes this system comprises switching system and base station system.Switching system comprises HLR (Home Location Register), MSC (Mobile SwitchingCenter), VLR (Visitor Location Register), AUC (Authentication Center) and EIR functional modules such as (Equipment Information Register), and the interface unit between switching system and base station system, other networking (comprising PSTN, ISDN, data network and other PLMN); The function that is achieved as follows: the registration of the periodicity of customer status, initialization, Customer Location renewal, switching, paging, MS caller, MS be called, discharge, flow process etc. mainly continues.The channeling technology of GSM can improve frequency efficiency greatly, thereby increases power system capacity; Intelligent network can be realized hand off and roaming function, thereby enlarges the customer service scope.It is perfect that The Application of Technology such as the time adjustment between time division multiple access (TDMA) frame structure, space diversity, time dispersive and equilibrium, base station and travelling carriage, speech coding, chnnel coding, interleaving technology, frequency hopping, secrecy provision are close to telecommunication service.Especially after introducing the SIM card technology, make radio communication jump out unclassified forbidden zone, as long as the hand-held card of client can be gone over the world.
The cdma cellular mobile communication almost is suggested simultaneously with GSM, but since the steady operation of this system be with at a high speed, the accurate power controls technology is prerequisite, be difficult at that time capture.Propose a plan up to QUALCOMM company and to have solved this difficult problem: by measuring the received power of travelling carriage and base station, and the power control mode that adopts open loop and closed loop to combine comes the order travelling carriage to adjust transmitting power, and the condition that makes output power levels keep proper property at travelling carriage is issued to minimum.Like this, alleviated the interference of travelling carriage on the one hand, helped to overcome channel fading on the other hand, made the application of CDMA CDMA (Code Division Multiple Access) become possibility, and drawn back the flourish prelude of CDMA digital cellular mobile communication systems thus other users.
In recent years, the Internet (Internet) technology has obtained develop rapidly and extensive use, based on its core technology---IP (Internet Protocol) thus the physics system of agreement has occupied the dominant position of data network framework.At present, the telecommunications network IP operation has accounted for more than 95% of teledata business, we can say Data-carrying network service basic I Pization.Along with the research and development of aggregation networks in the IP technological frame and the proposition of VoIP (Voice Over IP) technology, traditional voice service merges mutually with the data network communications business gradually.IP phone has been used in toll telephone in the telecommunications network Plain Old Telephone Service more than 70%.Therefore, broadband, the IP of network change into the inexorable trend into whole telecommunications network development.Develop and improve voip technology and then become a current research focus with the traditional voice service of comprehensive replacement.
Described voip technology is to be the technology that transmission platform is realized Speech Communication with the IP packet switching network based on router.The transmission of voice signal on IP network will through associate analog signal to conversion, the digital speech of digital signal be packaged into IP grouping, IP grouping by network transmit, the IP grouping unpacks processes such as reverting to analog signal with digital speech.Voice pick up the VOIP gateway of end and realize that mould/number conversion, encoding compression, the packing of voice signal are converted to processing such as IP traffic, speech data is placed in the packet or grouping of variable length, subsidiary addressing of each packet and control information, thus can send to the destination by network one with standing for a moment.The destination voip gateway comprises the processing of reception IP traffic: remove addressing and control information, keep the original speech data that is loaded, and it is offered decoder, be converted back to analog voice signal.IP transmission network between both-end VOIP gateway can be the combination in any of ip router and network link, and network link can be any topological structure or an access method of supporting IP traffic.Say that equivalently in a data channel, overall network is regarded as the equipment that an input received and within a certain period of time voice packet was sent to output; Same intermediate node in this network is checked the addressing information that each IP data is subsidiary, and utilizes this information to transmit this datagram toward the next stop on the path, destination.
The sharpest edges of described VOIP technology are, owing to adopt various advanced persons' speech coding scheme (mainly to adopt ITU-T G.711 at present to voice signal, G.723, and G.729), its needed transmission bandwidth only is 8kbit/s～12kbit/s, much smaller than the transmission bandwidth of legacy circuit-switched networks network 64kbit/s.Because the development of related hardware, software, agreement and standard breaks through, voip technology is very fast to be applied in fixed network, and is advanced further towards stronger, the more effective realization target of function and interoperability.
One of development trend of 3G system is the network all-IPization, mainly is meant the IPization of core network and user side, and emphasis shows network configuration IPization, protocol IPization and professional IPization, carrying, control and service detach, and network will be more flexible like this.Because traditional voice transmission is convenient, voice service remains main and the business proportion maximum in the 3G system.Realizing the IPization of user side, is not only to realize the integrated Packet data service of user side, and more prior is to realize the packet switched bearer of speech on wireless access.Therefore, be implemented in cordless communication network, also give birth to such as the end-to-end speech IP transmission among WLAN and the UMTS, and will become the main flow speech technology of following 3G along fortune with the Wireless VoIP technology.Develop this technology and can save bandwidth on the one hand, improve the availability of frequency spectrum; The interface and the platform of speech and uniform data can be provided to the user on the other hand.
Wi-Fi and WiMAX enter into rivalry in the world as the representative of present stage Wireless VoIP technology.WiMAX can be designed in public radio band, or needs to work on the radio band of license.It can with bigger frequency range, more multi-period and more high power transmit.In general, has only the WiMAX technology of wireless ISP (Internet Service Provider) dealer ability use authority frequency range, about 100 kilowatts of general through-put power.Wi-Fi then only is designed to work between 2.4GHz～5GHZ in public frequency range.US Federal Communication Committee (FCC) stipulates that its general through-put power is 1～100 milliwatt, only be 1,000,000 of WiMAX/.What therefore undoubtedly, the transmission range of WiMAX base station can be than WiFi base station is big.But because Wimax is based on the technology of radio band transmission with Wi-Fi, so limited by same physical law, if WiMAX equally is placed on the unauthorized frequency range with Wi-Fi, then this transmission advantage will disappear because of the frequency range competition at once.
The up-to-date MIMO of Wi-Fi has the high transmission speed of per second 108mbyte in theory, and the speed of 45mbps is also arranged under actual environment.And the product of WiMAX does not occur so far as yet, and the actual frequency range that talk about WiMAX still too early.Following these two kinds of technology will be complementary mutually with other radio network technique, makes the wireless online mode that action edge, more convenient more be arranged.
Above-mentioned the deficiencies in the prior art are: wireless ISP dealer uses WiMAX or Wi-Fi technology to build when putting the Wireless VOIP base station, if the scope that system transmissions covers is bigger, to run into a ubiquitous now frequency range competition difficult problem, be in the same channel, have more user and compete same frequency range simultaneously; If the scope that system transmissions covers is less, puts density but need to strengthen building of base station, thereby strengthen system cost.Therefore, be today of rapid growth in global mobile subscriber's quantity, frequency range competition and the problem of service quality (Quality of Service) management and control have restricted the further ripe utilization of these technology.Though the someone talks about WiMAX is added QoS mechanism, use for VoIP, make dual-mode handset on the mobile phone and on market, promote the use of though there has been the people that the Wi-Fi technology is added in, yet still actual result of use remain to be observed with actual economic benefit.
