Wherein, Beidou terminal has the function of positioning, short message data communication etc..Currently, Beidou terminal exists in reality scene
It can be influenced by a variety of causes when being communicated, substantially reduce communication success rate, carry out short message according to my corporate statistics Beidou terminal
When communication, if excluding the interference such as weather, barrier, clutter, transmitting-receiving success rate is 93%, by the comprehensive of various environmental factors
Group photo is rung under often generation, and success rate can drop to 85%, and the user volume of Beidou RD increases in recent years, is often generated and is avoided sky
The phenomenon that satellite channel congestion, big-dipper satellite can take transmission to inhibit function at this time, inhibit user's short message to send, in this feelings
The success rate that Beidou terminal is sent under condition is even more to drop to 50%, it is seen that it is inclined that Beidou terminal communicates success rate in actual use
Low, user experience is poor；End causes the unreliable transmission of Big Dipper short message mainly to have two big factors:
One, the data due to uncertain such environmental effects such as various interference, inhibition, when Big Dipper short message being caused to be transmitted
It loses.
Two, lack information feedback inhibition, sender is caused not know whether recipient receives short message, and recipient is not yet
Knowing sender, whether there is or not send short message.
Big Dipper short message transmission status (Fig. 1) in, throw into question factor one the reason of have at 3 points:
1. user sends an SMS to other side in execution, i.e. when information is transmitted to satellite by terminal A (Fig. 1 is 1.), due to
The reasons such as the various interference of the power of signal or environment, cause satellite not receive the short message that terminal A is sent.
2. terminal A emits short message to satellite, satellite receives short message, but since system inhibits, satellite does not forward short
Message, terminal B would not receive short message.
3. satellite receives the short message that terminal A is sent, and has been transmitted to terminal B (Fig. 1 is 4.), but due to terminal B signal
Power or environment the reasons such as various interference, cause terminal B to can not receive short message.
Throw into question factor two the reason of have at 4 points:
1, user sends an SMS to other side in execution, i.e. when information is transmitted to satellite by terminal A (Fig. 1 is 1.), due to
The reasons such as the various interference of the power of signal or environment, cause satellite not receive the short message that terminal A is sent, user does not know simultaneously
Road satellite is confiscated；Or satellite receives short message, but since system inhibits, satellite does not forward short message, and user does not know simultaneously
Whether there is or not forwardings for road satellite.
2, satellite receives the short message that terminal A is sent, and has been transmitted to terminal B (Fig. 1 is 4.), but due to terminal B signal
Power or environment the reasons such as various interference, cause terminal B to can not receive short message, the user of terminal A is not aware that terminal B has
Nothing receives short message.
3, terminal B has been received by short message, but the user of terminal A is not aware that whether terminal B receives short message.
4, satellite receives the short message that terminal A is sent, and has been transmitted to terminal B (Fig. 1 is 4.), but since terminal B is not opened
Machine, terminal B may can not receive short message, and the user of terminal B does not know yet and sent out short message either with or without user.
