Abstract
The invention provides a mobile communication network expansion communication system and method based on big dipper RDSS (radio data system) system, wherein one or a plurality of big dipper base stations nearly the same as the base station on the current mobile communication network are created, the base station is connected with the mobile communication network through a wire link and is connected with a mobile communication network based on a portable mobile communication base station or a wireless communication network formed by wifi route equipment beyond the signal coverage range of the mobile communication network through a big dipper satellite RDSS wireless short message link, and the two networks are used for realizing the short message communication of mobile equipment (cellphone) beyond the coverage range and the mobile equipment (cellphone) within the coverage range of the mobile communication network so as to expand the coverage range of the mobile communication network.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of mobile communications network based on Big Dipper RDSS system and expand communication system and method.
Background technology
Big Dipper RDSS system: the satellite system with short message communication function of China's independent intellectual property right;
Mobile communication system: based on the communication system of existing digital mobile cellular telecommunication network, such as the communication system of China Mobile, the communication system of CHINAUNICOM and the communication system of China Telecom.
Current, China has built up the digital mobile cellular telecommunication net that covers the whole nation multiple business is provided, and mainly comprises: voice service, short message service, data service.Mobile short message service (SMS) is suitable for amount of communication data and does not reach the transfer of data of the Embedded System Product of realizing long-distance measure and control in using etc. very much.
Mobile short message service is divided into 2 kinds of point-to-point short message and short message cell broadcaste services.Point-to-point short message service can make the user of GSM network can receive or send numeral or the Word message of finite length (being no more than 140 bytes), short message is the longest to be 140 English characters or 63 Chinese characters, if surpass this specific length, then will send several times.
Mobile short message service utilizes signaling channel to transmit, and it need not dial and connect, but directly the information that will send out is added that destination address sends to SMS service center, send to again final target terminal (mobile phone) by short message service center.If transmit unsuccessfully, the callee does not answer definite message, and the GSM network can keep transmitted breath, and called when can be called logical when finding, information can be retransmitted, accurately receives to guarantee the callee.
But because mobile short-message need to could normally be received and dispatched in the signal cover of mobile communication base station, so just need to build many mobile communication base stations, link together by communication line between these mobile communication base stations and just formed mobile communications network, mobile short-message can be received and dispatched in all mobile communication base stations in this mobile communications network, but owing to the cost of building the base station and the reason of environment, the mobile communication base station cannot reach seamless coverage, such as on the ocean or on the Gobi desert, just can't receive and dispatch mobile short-message, thereby can't with mobile communications network in other user's proper communications, very inconvenient.
Big Dipper RDSS system possesses the short message transmitting function, Big Dipper RDSS terminal equipment can utilize Big Dipper short message channel that text message is sent to big-dipper satellite with the form of short message in the zone that big-dipper satellite can cover and by big-dipper satellite this short message be sent to big-dipper satellite master station again, big-dipper satellite master station also can send short message to Big Dipper RDSS terminal equipment by opposite mode, thereby realizes communication.Owing to be that so its coverage is very wide take big-dipper satellite as information node, but owing to it must could realize communicating by letter with the cooperation of big-dipper satellite master station by Big Dipper RDSS terminal equipment, so it has again significant limitation.
Summary of the invention
The object of the present invention is to provide a kind of mobile communications network based on Big Dipper RDSS system to expand communication system and method, in zone that the mobile communications network signal can't cover (such as the ocean, high mountain, the Gobi desert), utilize Big Dipper RDSS short message channel and WIFI routing device or portable mobile communication base station to build and the mobile communications network signal coverage areas in mobile communication terminal (mobile phone) between SMS channel, expand the coverage of mobile communications network, bring the good user of mobile communication terminal (mobile phone) user and experience, thereby solve the foregoing problems that exists in the prior art.
