Abstract
The present invention proposes a kind of grouping polling method based on satellite communication, is related to satellite communication field.If the present invention solves current main website to the poll poll in small station using unicast, a polling request signaling must be sent out to each small station, if small station number is more, this poll signaling number can be multiplied, and can reduce efficiency of bandwidth use；If poll uses multicast, small station is allowed to be added specific group, so exist again and occupies multicast address, the problem of influencing the multicast service of service layer, its drip irrigation device are as follows: grouping poll signaling uses the IP packet of subnet broadcast, then the device id that poll is wanted in the content of the IP packet allows all small stations that can receive the signaling to realize；Small station is when handling the signaling, if the device id carried in signaling is oneself, is polled signaling processing, and reply poll response.The invention has the advantages that improving efficiency of bandwidth use, multicast address is not also occupied additionally.Suitable for satellite communication.
Description
Technical field
The present invention relates to communication technology of satellite, in particular to the grouping polling technique in satellite communication.
Background technique
In satellite communication system, under frequency division mode, when all small stations and master station communication, their channel parameter phase
Together, it may be assumed that
1, the channel parameter of receiving end of channel parameter and main website of the transmitting terminal in all small stations is identical；
2, the receiving end channel parameter in all small stations and the transmitting end channel parameter of main website are identical.
The control signaling in main website and small station is carried out by unicast message, and on the satellite link in main website and all small stations
It is one-to-many mechanism, i.e., a main website emits signaling, and all small stations can receive correspondence over the satellite link.Here it there is
Such a problem must send out a poll to each small station if main website uses unicast to the poll poll in small station
Demand signalling, if small station number is more, this poll signaling number can be multiplied, and can reduce efficiency of bandwidth use；If wheel
It askes and uses multicast, small station is allowed to be added specific group, occupy multicast address then exist again, influence the multicast service of service layer.
Summary of the invention
The object of the present invention is to provide a kind of grouping polling method based on satellite communication, solves current main website to small station
If poll poll uses unicast, a polling request signaling must be sent out to each small station, if small station number is more,
This poll signaling number can be multiplied, and can reduce efficiency of bandwidth use；If poll uses multicast, small station is allowed to be added specific
Group, the problem of occupying multicast address then existing, influence the multicast service of service layer again.
The present invention solves its technical problem, the technical solution adopted is that: the grouping polling method based on satellite communication, including
Following steps:
The website number N of each poll is arranged in the main website network management page in step 1, user；
Step 2, main website successively choose the equipment in N number of small station according to the website number N of each poll from all small stations
ID is encapsulated into poll signaling；
Step 3, main website issue packaged poll signaling in the form of subnet broadcast；
After step 4, all small stations receive the subnet broadcast, the small station device id in signaling is decoded, if carried
Small station ID in have oneself ID, then need to reply poll response, otherwise, directly abandon the poll signaling；
Step 5, main website are directed to the website of remaining non-poll, repeat step 2-3.
The invention has the advantages that grouping poll signaling is adopted by the above-mentioned grouping polling method based on satellite communication
With the IP packet of subnet broadcast, the device id of poll is then wanted in the content of the IP packet, allows all small stations to realize
The signaling can be received；Small station, if the device id carried in signaling is oneself, is polled signaling when handling the signaling
Processing, and reply poll response.It needs to be grouped polling purpose according to user to realize, also reduces to greatest extent
The complexity of polling message and system, meanwhile, multicast address is not also occupied additionally.
Specific embodiment
Below with reference to embodiment, the technical schemes of the invention are described in detail.
Grouping polling method of the present invention based on satellite communication, includes the following steps:
The website number N of each poll is arranged in the main website network management page in step 1, user；
Step 2, main website successively choose the equipment in N number of small station according to the website number N of each poll from all small stations
ID is encapsulated into poll signaling；
Step 3, main website issue packaged poll signaling in the form of subnet broadcast；
After step 4, all small stations receive the subnet broadcast, the small station device id in signaling is decoded, if carried
Small station ID in have oneself ID, then need to reply poll response, otherwise, directly abandon the poll signaling；
Step 5, main website are directed to the website of remaining non-poll, repeat step 2-3.
Here, the broadcast characteristic based on channel in satellite communication, grouping poll signaling use the IP packet of subnet broadcast, so
The device id for wanting poll in the content of the IP packet afterwards allows all small stations that can receive the signaling to realize；Small station exists
When handling the signaling, if the device id carried in signaling is oneself, it is polled signaling processing, and reply poll response.
It needs to be grouped polling purpose according to user to realizing, also reduces answering for polling message and system to greatest extent
Miscellaneous degree, meanwhile, multicast address is not also occupied additionally.
Embodiment
Grouping polling method of the embodiment of the present invention based on satellite communication, includes the following steps:
The website number N of each poll is arranged in the main website network management page in step 1, user, and in this example, N is preferably 2；
Step 2, main website successively choose the equipment in 2 small stations according to the website number 2 of each poll from all small stations
ID is encapsulated into poll signaling, and in this example, the small station of selection is B and C；
Step 3, main website issue packaged poll signaling in the form of subnet broadcast；
After step 4, all small stations receive the subnet broadcast, the small station device id in signaling is decoded, if carried
Small station ID in have oneself ID, then need to reply poll response, otherwise, directly abandon the poll signaling, in this example, small station B
It will restore poll response with C, small station A and D will directly abandon the poll signaling；
Step 5, main website are directed to the website of remaining non-poll, repeat step 2-3.
Claims (1)
1. the grouping polling method based on satellite communication, which comprises the steps of:
The website number N of each poll is arranged in the main website network management page in step 1, user；
Step 2, main website successively choose the device id in N number of small station according to the website number N of each poll from all small stations,
It is encapsulated into poll signaling；
Step 3, main website issue packaged poll signaling in the form of subnet broadcast；
After step 4, all small stations receive the subnet broadcast, the small station device id in signaling is decoded, if what is carried is small
