Abstract

Method is reissued the invention discloses a kind of Big Dipper RDSS short messages, including：S1. the first Big Dipper RDSS terminals send short message to the second Big Dipper RDSS terminals；S2. detect whether first Big Dipper RDSS terminals are successfully transmitted the short message, if so, then performing step S3；S3. detect whether second Big Dipper RDSS terminals receive the short message, if so, then the short message is sent successfully, otherwise forward the short message to second Big Dipper RDSS terminals by default communication protocol, perform step S3.The present invention realizes Big Dipper RDSS terminals from that can not receive short message State Transferring into can receive after short message state, still the short message that other Big Dipper RDSS terminals are sent to it in the case where that can not receive short message state before can be received, the round-the-clock short message receiving ability of Big Dipper RDSS terminals is realized.

Description

A kind of Big Dipper RDSS short messages reissue method
Technical field
The present invention relates to Beidou communication technical field, more particularly to a kind of Big Dipper RDSS short messages reissue method.
Background technology
Chinese Beidou satellite navigation system (BeiDou Navigation Satellite System, BDS) be China from The GPS that row is developed.It is after american global positioning system (GPS), Russian Glonass satellite navigation system (GLONASS) the 3rd ripe satellite navigation system after.Beidou satellite navigation system (BDS) and GPS of America, Russia GLONASS, European Union GALILEO, are the suppliers that the satellite navigation committee of the United Nations has been assert.
Beidou satellite navigation system is made up of space segment, ground segment and the part of user segment three, can whole day in the world Wait, round-the-clock provides high accuracy, highly reliable positioning, navigation, time service service for all types of user, and has short message communication capacity, Through tentatively possessing area navigation, positioning and time service ability, 10 meters of positioning precision, the meter per second of rate accuracy 0.2, time service precision 10 is received Second.
On December 27th, 2012, the formal version 1.0 of dipper system spacing wave ICD is formally announced, Beidou navigation Business is formal to provide passive location, navigation, time service service to the Asian-Pacific area.On December 27th, 2013, Beidou satellite navigation system Formal offer regional service anniversary news briefing is held in Information Office of the State Council's press hall, formal issue 《Dipper system discloses service performance specification (1.0 editions)》With《Dipper system spacing wave ICD (2.0 editions)》Two System file.On November 23rd, 2014, IMO maritime safety committee has been approved to Beidou satellite navigation system The navigation safety circular of system accreditation, this indicates that Beidou satellite navigation system formally turns into the composition of Global Radio Navigation System Part, obtains the international legal status towards maritime applications.The satellite navigation system of China has obtained recognizing for International Maritime Organization Can.
Compared to other existing satellite navigation systems, Beidou satellite navigation system has short message communication, i.e. Big Dipper system System user terminal has bi-directional communication function, and user can once transmit the short message information of 40-60 Chinese character.Due to north Bucket RDSS communication modes are that first short message is sent on big-dipper satellite by a RDSS Big Dipper terminal, then are sent by big-dipper satellite To another RDSS Big Dipper terminal, but it is to send successful that may have transmitting terminal in this process, and receiving terminal by This short message can not be received in certain situation (no signal or in off-mode), losing for this short message is directly resulted in Lose.
The content of the invention
Method is reissued it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of Big Dipper RDSS short messages, is solved It can not receive short message state because Big Dipper RDSS terminals are in and cause the problem of short message is lost.
The purpose of the present invention is achieved through the following technical solutions：A kind of Big Dipper RDSS short messages reissue method, including：
S1. the first Big Dipper RDSS terminals send short message to the second Big Dipper RDSS terminals；
S2. detect whether first Big Dipper RDSS terminals are successfully transmitted the short message, if so, then performing step S3；
S3. detect whether second Big Dipper RDSS terminals receive the short message, if so, then the short message is sent into Work(, otherwise forwards the short message to second Big Dipper RDSS terminals by default communication protocol, performs step S3.
It is preferred that, detect that the method whether first Big Dipper RDSS terminals are successfully transmitted the short message is：First north When bucket RDSS terminals affiliated Big Dipper operation centre receives Big Dipper operation master station and pushes the short message come, then the short report Text is sent successfully.
It is preferred that, detect that the method whether second Big Dipper RDSS terminals receive the short message is：First north The affiliated operation centre of RDSS terminals struggle against to the transmission communication inquiry request of Big Dipper operation master station, it is whole to inquire about second Big Dipper RDSS Whether end receives the short message.
It is preferred that, the method for forwarding the short message to second Big Dipper RDSS terminals is：First Big Dipper RDSS terminals The short message is cached to caching server by the Big Dipper operation centre, with the 3rd Big Dipper RDSS of the Big Dipper operation centre Terminal forwards the short message according to default communication protocol to second Big Dipper RDSS terminals.
It is preferred that, the step S3 also includes：When detecting second Big Dipper RDSS terminals reception short message, The first affiliated Big Dipper operation centre of Big Dipper RDSS terminals detects whether there is the short message in its caching server, if so, then clear Except the short message in the caching server.
It is preferred that, will be described short during by default communication protocol to second Big Dipper RDSS terminals forwarding short message Message is packaged as forwarding communication pack arrangement and is transmitted, and the forwarding communication pack arrangement includes：Message header, originating party card number, Bao Xu Number, message length, message body and verification；Originating party card number is used for the card number for storing first Big Dipper RDSS terminals；Bag sequence number is used Counted in data storage bag；Message length is used to store in addition to message header, originating party card number, bag sequence number, message length and verification Message body length；It is described to verify for storing message header, bag sequence number, command number message length, message body and the value of inspection.
The beneficial effects of the invention are as follows：The present invention realize Big Dipper RDSS terminals from can not receive short message State Transferring into Can receive after short message state, still can receive in the case where short message state can not be received before other Big Dipper RDSS terminals to The short message that it sends, realizes the round-the-clock short message receiving ability of Big Dipper RDSS terminals.
