Description
Technical field
The present invention relates to communication technique field, more particularly, relate to a kind of graph text information receiving/transmission method based on the existing caller identification communication protocol standard of local telephone system.
Background technology
Up to now, main still based on traditional voice service in the telecommunications service that telephone user provides at telecommunication department, these 2 years recently, the service that telecommunication department in all parts of the country has been opened CLIP service in succession, increased the receivable amount of information of certain user, certain facilitation has been played in the universal and development of telephone set.Caller ID display (CID) also is known as caller identification.Say simply, be exactly that the called party hears a moment behind the bell ring, just can see on the LCDs of telephone set of oneself and squeeze into number or other relevant information (telephone set of reception must have incoming call display function) that this phone person uses telephone set, the user can according to circumstances select whether to answer.
Have two kinds from switch to telephone set CID signal transmission standard in the world at present: FSK (frequency shift keying) and DTMF (dual-tone multifrequency), in each standard, various countries have concrete specification pattern again.Only do simple an introduction below with regard to the FSK standard.The branch that ITU-TV23 and BELL202 are arranged again in the FSK standard, key property relevant with FSK in these two kinds of standards contrasts as shown in Table 1:
We know that telephone set will be realized its incoming call display function, need the cooperation support of stored-program control exchange just can finish.But what telephone line transmitted is audio signal, and the confidential handle of programme-controlled exchange is transferred to the somewhere with the digital signal of high level " 1 " and low level " 0 " expression by voice-grade channel
Table one
Point just must adopt suitable modulator approach.If we become 1300Hz to numeral " 1 "; Digital " 0 " is become 2100Hz, and digital signal just can have been transmitted in voice-grade channel, and this method just is called the FSK modulation.Certainly in the circuit except the signal of 1300Hz and 2100Hz, also with duration of signal, rate of change is relevant, generally adopts the speed rates of 1200 bauds, the main component in its frequency spectrum is substantially included in the voice-grade channel.After signal has arrived communication terminal and has been telephone set, CPU in the telephone set will adopt the FSK decoding processing opposite with stored-program control exchange (coding) to signal, after solving for information about, deliver on the display screen of this machine, the user just can see the telephone number squeezed into before answering.
In general, it is very limited that the amount of information that adopts the dtmf code mode to be collected is compared with the FSK coded system, even but adopt this coded system of FSK, in existing technology, the amount of information that can provide to the user also be very limited.At present, in the service of the caller ID display that domestic telecommunication department provides, also only the date and time of having sent incoming call than DTMF in the incoming information that the FSK mode is provided more.
Therefore, no matter being based on DTMF still is the caller ID display service that the FSK standard realizes, a kind of single information of telephone number of calling party all can only be provided, and makes amount of information very limited.
Before the caller ID display technology was not applied as yet, the service that telecommunication department provides to telephone user only limited to traditional speech and transmits.Amount of information is very limited, continuous development along with information technology, people will be more and more stronger to craving for of information, therefore, this telecommunications service that increased caller ID display on the basis that traditional speech transmits can not satisfy growing the craving for information service of people well with the telephone set of realizing this function, the user feels that still existing telephone functionality is single in the family, and the information that can receive is limited, and in use still can feel has too many not enough and restriction.
Such as, considerable telephone user just wishes to utilize the telephone set in the family to realize the transmission of multiple information resources and share the reception of various information, inquiry etc. very much.Though the development of INTERNET net is very fast at present, but most countries in the world comprises China after all, the popularity rate that remains telephone set is higher than the popularity rate of computer and INTERNET net far away, therefore how to make full use of the infrastructure (comprising circuit and relevant device thereof) of existing telecommunication system, provide information service as much as possible to existing telephone machine user to greatest extent, promptly except that traditional speech transmission and caller ID display service, also comprise to the user various literal are provided, character and figure, information such as image, under the prerequisite that INTERNET nets on not having ready conditions as yet, utilize the telephone set in the family, just can enjoy the infrastructure service function that part is similar to the INTERNET net, this thinking meets China's actual conditions, therefore realization of the present invention will greatly promote and promote the development of China's information technology and related industry, China is taken its place in the front ranks of the world digging the technology that exhausts aspect the existing communication equipment potential, this be facilitate that the present invention produces source and thought.
