Current society is entering informationalized epoch, and the development pole the earth of the communication technology and internet is changing people's life style.Along with the development of society, the people's activities scope is increasing, and more and more uncertain.This mobility and uncertain when bringing market and challenge to mobile communication, also for the location-based service business carry out and expansion has brought infinite commercial opportunities.
In numerous information systems, and GIS (Geography Information System: GIS-Geographic Information System), owing to bring great convenience for people's trip, activity and life, so be favourably welcome.GIS has been widely used in Internet now and has gone up (as WEBGIS: by web page display and realize the application of GIS).
In mobile communication technology, location-based service is the cooperation by wireless terminal and wireless network, determines mobile subscriber's actual geographical position, thereby provides the required information on services relevant with the position to the mobile subscriber.It comprises location technology and positioning service two major concepts, and wherein, location technology can be divided into different kinds according to the difference of wireless network, mainly comprises: based on mode, the modes such as EOTD, A-GPS of CeIIld+Sector; And positioning service is called shift position service (Location Based Service, LBS), it is a positional information (latitude and longitude coordinates) of obtaining mobile phone users by the network of telecommunications mobile operator (as GSM net, CDMA net etc.), the customer position information that provides according to wireless network, the various breeding properties that binding site service provider SP (Service Provider) can provide, thereby present a kind of value-added service to the mobile subscriber based on current location, as: vehicle scheduling, stroke tracking, assets monitoring etc.
Global positioning system (Global Positioning System-GPS) was built up in 1994 comprehensively, had the new generation satellite navigation and the navigation system of carrying out comprehensive real-time three-dimensional navigation and stationkeeping ability in sea, land and sky.Use through nearly 10 years departments such as China's mapping shows, GPS is with distinguishing features such as round-the-clock, high accuracy, automation, high benefits, win vast mapping operations person's trust, and successfully be applied to multiple subjects such as geodesic survey, engineering survey, aerophotogrammetry, delivery vehicle navigation and control, crustal movement monitoring, engineering project deformation monitoring, resources survey, geodynamics, thereby bring the field depth technological revolution at quarter to survey field
Note is to follow digital mobile communication system and a kind of telecommunication service of producing, by the signaling channel and the signaling network of mobile communication system, transmits literal or numeric messaging breath, belongs to a kind of data communication service of non real-time, non-voice.Note can be started by mobile communication terminal (mobile phone), also can be started by the SMS platform server of Mobile Network Operator, also can be by starting with the interconnected network provider SP (comprising ICP, ISP etc.) of mobile operator SMS platform.
From realizing the technological means of short message service function, occupy dominant position though send and receive point-to-point message by mobile phone terminal, and not exclusive form, landline telephone, Personal Handyphone System and the Internet are becoming new instrument and carrier.
At present the short message protocol supported of mobile phone also is that multi-media protocol mainly contains three kinds of SMS, EMS and MMS, below these three kinds of SMS (Short Message Service) is done a brief introduction:
SMS (Short Messaging Service) is promptly: short message service.It is short message service the earliest, also be the highest a kind of short message service of present popularity rate, by receiving and dispatching note mutually between its mobile phone, content is based on the non-text data of text, numeral or binary system, at present, the length of this short message is limited within 140 bytes.SMS is subjected to users' welcome with function of use simply and easily, popularizes rapidly, but is the wireless data service that belongs to the first generation all the time, has the restriction of technical standard in content and application facet.
EMS (Enhanced Message Service) Chinese means the enhanced short message service.It comes compared with SMS, and its advantage is except sending as SMS the short text message, can also sending information such as simple image, sound and animation.And on the GSM network of its bigger advantage to be EMS still may operate in original SMS operation, and on transmission approach and method of operation, there is not difference yet.This standard belongs to open, thus any to EMS interested third parties company or individual can be on this platform the Application and Development software and services.But because various mobile phone brands exist technical incompatible situation, in actual use often can only be in the mutual transmission more than could realizing between the mobile phone of same brand, so practicality remains further raising.
MMS is the abbreviation of Multimedia Messaging Service, Chinese is translated into MMS (Multimedia Message Service), also claim " multimedia message ", be that standard according to 3GPP also is the up-to-date business of standard development of the relevant multimedia messages of standard of WAP Forum, the characteristic of its maximum is supported multimedia function exactly, can be under the support of GPRS, CDMA 1X, 3G, EDGE, with the WAP WAP (wireless application protocol) is that carrier transmits video clip, picture, sound and literal, load mode can also be the transmission between mobile phone and the computer except transmitting between mobile phone.Unique distinction with mobile phone of MMS function is the media editing device that it is built-in, makes the user can write multimedia messages easily.If mobile phone has an internal or external camera,, and they are sent to friend or colleague just the user can produce the information or the electronic post card of PowerPoint form.At present, this application service moves to maturity gradually, becomes the messaging format of main flow.
MMS is " third generation short message service " after SMS (SMS (Short Messaging Service)), EMS (Enhanced Message Service).SMS can only receive and dispatch text message, EMS can add the tinkle of bells, simple figure and simple animation in text SMS, MMS has expanded the media types that can receive and dispatch greatly, text, simple picture and the tinkle of bells all can transmit, complicated picture such as photo, large-scale chart and the transmission of snatch of music, the effect that video clipping then can better be brought into play MMS.
Message service system is supported the form of two kinds of messenger service at present, the one, between mobile phone and the website: user's program request a piece of news to the website, SP is again sending to the cellphone subscriber, or mobile phone sends a piece of news for the shortcode of website, new record is separated to this message in the website, situation according to definition is transmitted, replys, or the storing message content.The 2nd, between mobile phone and the mobile phone: the cellphone subscriber uses message editing function edit messages, then sends a message to the SP end, and SP is transmitted to target mobile phones again.At present the SP end only is processing to form to the processing of message, does not comprise the processing to content as yet.
It has been technology trends that above-mentioned various technological services and resource comprehensive are used, and the development of technology is for more intelligentized service is provided, and the present invention just is being based on such background and is producing.
