Description
The present invention relates to a kind of digitlization, broadband, synthesization, personalization, and have the terminal equipment and the using method thereof of certain mobility, or rather, relate to a kind of broadband multi-purpose digital intelligent telephone and using method thereof.
Development of Communication Technique can be described as advances by leaps and bounds, and the rapid expansion in communication service market of Yin Faing and communication technology market thus causes people's life style that deep variation takes place.On the one hand, development of Communication Technique makes people can realize means of communication and the mode that can't imagine several years ago; On the other hand, the user's communications demand constantly expands, and new communication requirement continues to bring out, from and promoted development of Communication Technique.Say that briefly the overall trend of Communication Development is digitlization, broadband, synthesization, personalization, intellectuality and mobility, one of important technology of realizing this goal is and the closely-related terminal technology of thousands upon thousands people that communicate.
Transmission system and switching system are two important component parts of communication network.When the transmission system of communication network and switching system all adopted digital technology, this net just was called integrated digital network.When realizing multiple different information communication after digitized processing in such network, this network just is called integrated services digital network (English is abbreviated as ISDN).ISDN was developed in 1970's, worldwide was used widely now.Fig. 1 has showed the structural representation of existing digital telephone system based on the N-ISDN technology.
Referring to Fig. 1, ISDN terminal TE is connected on the network terminal NT1 equipment by the S/T interface, and network terminal NT1 is connected to isdn switch by user's twisted-pair feeder.Network terminal NTl generally is responsible for being installed in user resident by telecom operation department.A network terminal NT1 can connect a plurality of terminal TE.Network terminal NT1 is responsible for network management, test and performance monitoring, and can solve a plurality of terminal TE problem of competition bus simultaneously.ISDN terminal can be digital subset, G4 class fax, video telephone or the computer that is inserted with the ISDN multifunction card etc.Non-ISDN terminal (as traditional phone) then will be connected on the NT1 through a kind of equipment that is called terminal adapter TA.
Terminal TE is structurized to the direct physical channel of isdn switch, is called the 2B+D channel.A B channel is 64Kbps, and a D channel is 16Kbps.Two B channels and these three channels of D channel are to use separately generally speaking.Can utilize two B channels that the band width in physical of 128Kbps is provided by means such as similar inverse multiplexing technology.The D channel can be by the mode statistic multiplexing of a plurality of terminals with competition, can be used for signaling message transmission and some low-speed data services.The B channel provides voice service, also can provide data service, the similar special line of B channel this moment.Such structure can provide speech, data and low speed graphic service on a physical channel, but we can see that the N-ISDN digital telephone set has significant limitation in the middle of the analysis below.
Shown in Figure 2 is the cardinal principle block diagram of N-ISDN digital telephone set terminal.Because since 1970's, the ISDN technology is full-fledged already, wherein a lot of modules can realize in a chip.As shown in Figure 2, microprocessor, oscillator, RAM, ROM constitute the control unit of this phone; Keyboard, liquid crystal display device and receiver, loud speaker constitute its man-machine interface, and being responsible for receiving user instruction is information.Hook switch or switch be used for producing pluck, on-hook signal; Unit such as the speech processes that links to each other with microprocessor by cpu i/f, B channel multiplexing, D Channel Processing, line interface constitute ISDN Channel Processing and control section, and these parts are controlled by microprocessor.Protection generally comprises voltage protection, current protection and transformer with the generation circuit.
N-ISDN is based on that black phone switching network technology PSTN grows up, compare with the traditional analog phone, it can also provide data communication service except voice service can be provided, but say that with regard to its essence it still belongs to the terminal technology based on circuit mode.In this manner, the bandwidth that can use of terminal is subjected to huge restriction.Be in particular in the following aspects:
1) the terminal bandwidth that can take is classification, and kind is less.Can only use a B channel as the user, or two B channels, the statistic multiplexing of D channel is very limited.The user is difficult to obtain 16Kbps to the bandwidth between the 64Kbps, and is same, and the user is difficult to obtain 64Kbps to the bandwidth between the 128Kbps.This different user that is unfavorable for that demand varies uses.
2) terminal is a narrowband terminal, and the bandwidth greater than 2Mbps can't be provided, thereby can't satisfy the demand of user to high speed, broadband services, as video traffic, high-speed multimedia business, switch type inquiry business and high-speed data access service.
3) terminal adopts towards the connected mode busy channel.That is to say that terminal monopolizes channel in communication process, when information sent, as alternately speaking and the reticent stage of both call sides, other terminal also can't busy channel.So just cause the significant wastage of bandwidth.Particularly during the terminal processes burst service, this point is even more important.As when being inserted with the computer internet of ISDN multifunction card, it carries out transfer of data probably in few time, and browsing page or processing in most times, analytical information.
4) terminal can be monopolized the physical channel bandwidth resources for a long time, causes other telex network demand to satisfy, and this just can't guarantee the fairness of occupied bandwidth resource between the user.Under the increasing communication environment of paroxysmal data service proportion nowadays, this point is difficult to meet consumers' demand.
5) number of terminals of shared same physical channel is seldom, the equipment that generally is connected on the NT1 is no more than 8, the user that can receive service simultaneously is no more than 3, thereby makes several terminals just must set a physical channel and a NT1 equipment, an exchange interface.
6) use of ISDN terminal business in isdn switch is based on time gas exchange, and user port speed is lower, is difficult to the raising capacity and improves integrated level, and it is also bigger with the difficulty that reduces operation cost to reduce volume.
Conventional voice communications is nearly all used terminal and network technology based on circuit mode.Because in the communication network based on circuit mode, terminal and switching technology are all fairly simple, time delay guarantees easily, is the main flow of communication network, particularly telecommunications network in for a long time in the past based on the communication technology of circuit mode therefore always.In such network, customer service is connected to switch by low speed line.The exchanger user level is multiplexed into them on the high-speed time-division multiplex TDM bus and handles.Carry out in the process in communication, subscriber's line, exchange resource, transfer resource all monopolized by the user.This mode can be brought many problems.
At first, exchange is that unit handles with the subscriber's line band width in physical, and this causes the node capacity to be difficult to improve.General switching node has only 16K * 16K or lower exchange capacity.Switching node is essential by certain concentrated than design, is determined by user's telephone traffic as the probability of CU switching node.The exchange capacity of switching node will and allow certain probability of call loss to design by the distribution of user's telephone traffic.Such network has the expandability of non-constant.Because after network builds up several years, user's telephone traffic distributes and has bigger variation.As because last netizen is too many, cause call loss to strengthen, not any strange thing in present many countries.
Secondly, directly or indirectly distinguish the user, make many users can't add up shared network resource, cause Internet resources to become hundred times waste, be unfavorable for handling burst service with band width in physical.User bandwidth is classification, fixing in addition, is unfavorable for that the user dynamically adjusts shared network physical resource, is unfavorable for that the user is to the multifarious demand of business.
At last, user's band width in physical speed range is too narrow, can't open broadband services.
