Description
Technical field
The present invention relates to communication technical field, relate in particular to fixed communication network system and terminal with note and broadband access function.
Background technology
Along with the high speed development of mobile communication technology, the mobile communications network scale constantly enlarges, and new business continues to bring out, and has formed substituting competition with fixed telecommunication network.The number of mobile users of China in 2003 begins to surpass fixed telephone subscriber's number, and both gaps constantly enlarged in recent years.According to the statistics of in May, 2007 information Estate Division, Chinese telephone subscriber reaches 8.5 hundred million, and wherein the fixed telephone subscriber reaches 3.71 hundred million, comprises nearly 100,000,000 Personal Handyphone System Personal Handyphone System(PHS) user, and fixed line penetration is 28.1%, and a month recruitment is about 1,000,000 families; And the mobile subscriber reaches 4.87 hundred million, and the mobile phone popularity rate is 35.3%, and a month recruitment is about 6,000,000 families, has had more more than 100,000,000 than the fixed telephone subscriber.
Mobile communication operator provides abundant business for its user, as note (also claiming short message), multimedia message and relevant value-added service.The growth at full speed of business such as note has brought huge profit, and only the first quarter in 2007, the note traffic volume just reached 1,826 hundred million, increased about 38% than the same period last year.This shows SMS substantially and voice functions of equal importance.Say to a certain extent, can not regard note as a kind of value-added telecom services simply, and can regard a kind of basic business as.But the great market of note and related service thereof generation at present and profit are moved telecom operators substantially and monopolize, and fixed telecommunication operator obtains very few.Therefore, fixed telecommunication operator is necessary to utilize the existing fixed telecommunications network to carry out fixed net short message and related service very much:
(1) through the development of more than ten years, fixed telecommunication network covers the whole nation, has reached the villages and small towns one-level substantially, and network is very ripe, stable performance, and the user is numerous.But user's average consumption value (ARPU value, Average Revenue Per User) reduces year by year, is necessary to release new business, excavates the great potential of existing network.
(2) fixed telecommunication network is mainly based on voice service, and value-added service is also mainly based on voice service, and business is relatively deficient; Broadband data service then is subject to the popularity of computer.Therefore, present business has big limitation, is necessary to release the non-speech service that can be independent of computer.
(3) fixed telecommunication operator has greatly developed radio local telephone network in recent years, mature and stable business platforms such as note have been set up, carry out various value-added services on this basis, and realized and the interconnecting of the business such as note of mobile communication operator, accumulated abundant operation experience.Carrying out short message service on the net at fixed telecommunication can make full use of existing business platform and interconnect advantage.
(4) radio local telephone network only is positioned as " replenishing and extension of fixed telecommunication network " on development policies; From technical standpoint, fixed wireless network has wireless access and the switching system of oneself, and homing position and VLR Visitor Location Register, is the network of a stack; From the market angle, invest atrophy gradually, market constantly dwindles.Therefore if can also carry out short message service on the net at fixed telecommunication, on speech and non-speech service, fixed telecommunication network and fixed wireless network can be merged, integrate the all-network resource, will help to promote the value of whole network, and improve the status of fixed telecommunication operator.When mobile operation license being arranged from now on and disposes the mobile network, can share the existing business platform, further realize the fusion of the speech and the non-speech service of the whole network.
(5) on the basis of business such as note, can provide various value-added services, also can carry out various new business,, develop international note as the fixed net short message business between the country based on note.
The notion of fixed net short message just proposed as far back as calendar year 2001, existing fixed net short message business typically refers to the phone (being called information terminal) that has function of receiving and sending short message with an one, in receiving or send by telephone wire, the foreign language short message, and can program request, a kind of service of customization various information.Its implementation is to set up speech channel between user terminal and fixed net short message platform, transmits user data according to certain communication protocol by sending FSK (Frequency Shift Keying) or DTMF (DualTone Multi-Frequency) signal then; The transmission rate of FSK and DTMF is all lower, and the actual transfer rate of FSK is about 720 bps, and the actual transfer rate of DTMF is about about 40 bps.
Although beginning in 2002 is disposed existing fixed net short message business in coastal cities such as Chinese Guangdong, Zhejiang, Shanghai, Tianjin, never applied on a large scale, mainly be because following shortcoming is arranged:
(1) existing fixed net short message is that note is realized as a kind of specific business, need adopt specific modulation demodulation system to transmit note data specially on subscribers feeder, and whole proposal has been ignored the data service characteristic of note, lacks flexibility and autgmentability.
(2) implementation method of existing fixed net short message is based on the speech channel transmission, need set up speech channel between user terminal and fixed net short message platform, can not make a phone call when therefore sending note; And the download that the fixed net short message platform is initiated when called subscriber busy can fail, though have retry mechanism number of retries and the too high meeting of frequency configuration that overall system efficiency is descended.
(3) transmission rate of existing fixed net short message is low, transmitting time is long, number of words is few, terminal and professional expandability are poor.
(4) user need be replaced by information terminal to ordinary telephone set.
The tinkle of bells when (5) information terminal can mask information centre's transmission information, and plain old telephone can't the mask information center ring of incoming call, when therefore extension set being installed, outside line can only link to each other with information terminal, plain old telephone must force to link the extension set mouth of information terminal, otherwise extension set all can ring when receiving information at every turn.
(6) clients such as ISDN (Integrated Service Digital Network), ADSL (Asymmetric Digital Subscriber Line) and Private Branch Exchange PBX wouldn't use the fixed net short message business.
(7) optical fiber connecting method such as FTTB, FTTH will obtain large-scale commercialization in the near future, and full light inserts or photoelectricity mixing access will become main flow, and existing fixed net short message mode can not continue to be suitable for.
At present, the broadband services development rapidly, ADSL, ADSL2+, VDSL (Very-high-bit-rate Digital Subscriber Line), VDSL2, BPON (Broadband Passive Optical Network), EPON (Ethernet PassiveOptical Network), GPON (Giga Passive Optical Network), Ethernet, Wireless Local Loop WLL (Wireless Local Loop), and HFC broadband access technologys such as (Hybrid Fiber Cable) provides good access means for the user.
With ADSL is example, can use frequency division multiplex or ECT echo cancellation technique on existing copper telephone wire, to provide low speed speech, high-speed downstream and middling speed up three channels simultaneously, upstream rate can reach 1 mbit/, and downstream rate can reach 8 mbit/.In recent years broadband services development rapidly, universal scope more and more widely, broadband services has become the main business growth point of fixed telecommunication operator.According to statistics, Chinese wide band access user had broken through 5,000 ten thousand in 2007, and the broadband user breaks through 100,000,000; And, begun to promote mainly Fiber to the home FTTH (Fiber To The Home) in world developed country.
By above analysis as can be known: be necessary very much to utilize the existing fixed telecommunications network to carry out note and related service; The implementation method of existing fixed net short message has many weak points, is necessary to adopt new method to realize fixed net short message and related service thereof; The maturation of Personal Handyphone System(PHS) and broadband access technology has been laid good basis with popularizing to the fixed net short message new method.The applicant has proposed the present invention through long-term creation exploitation.
