Description
Technical field
The present invention relates to a kind of business transmitting methods of low time delay resources control in satellite network.
Background technology
In satellite network, terminal is before business transmission, it is necessary first to which obtaining time interval resource could transmission packet.Time slot
Occupancy mode be divided into fixed allocation, three kinds of modes of random access and distribution according to need.For the time slot of fixed allocation, terminal can be with
Directly occupy slot transmission data packet；For the dynamic slot of random access, terminal needs to seize time slot and transmission packet；It is right
It is described as in the basic process of the time slot of distribution according to need, terminal traffic transmission:1) terminal sends business by uplink control channel
Transmission resource request signaling；2) master controller SMAC layers of resource management module distribute time interval resource, pass through down control channel
Send the time slot of distribution；3) terminal receives the time slot of distribution, transmits and receives confirmation message.4) terminal occupies the time slot hair of distribution
Send data packet.As it can be seen that different modes obtains the mode of time interval resource and content is different, satellite network passes through MAC layer
(SMAC) requests for capacity of resource controlled block realizes that service access is transmitted with data packet with resource allocation function.
SMAC layers of satellite network supports continuous rate-allocation, the dynamic capacity allocation based on rate, the dynamic based on flow
Capacity distributes and idle capacity distributes four kinds of allocation algorithms.
Continuous rate-allocation does not need terminal and sends requests for capacity, and satellite controller is by way of static fixed allocation
Terminal distribution time slot is issued to terminal by control channel, after terminal receives the time slot of distribution, is uploaded in the time slot of distribution
Defeated business, if transmitted without business, which keeps idle state.
Dynamic capacity allocation mode based on rate and flow needs terminal to report business by uplink control channel first
Transmission capacity/rate transmission requirements, master controller distribute after channel, and the time slot of distribution, terminal are returned by control channel
Reception confirmation message is reported by control channel, then occupies assigned slot transmission data packet.
Idle capacity distribution refers to that, without any request, satellite controller is directly that terminal distribution is held according to configuration file
Amount, and redundancy idle channel distribution condition is sent to by terminal by control channel, this method of salary distribution belongs to Redundant binary number, mesh
Preceding use it is fewer.
By on-demand business transmission process it is found that SMAC layers of resource control scheme will not only solve distributing slot resources asks
Topic also needs to the signalling interactive process of reasonable design.
Continuous rate allocation schemes are simple and practicable under the scene of low user capacity, but with the increase of user capacity,
It is increasingly severe that user is successfully accessed the delay problem that probability is lowly brought.Dynamic capacity allocation mode based on rate/flow
Belong to distribution according to need mode, the transmission demand of user can be met, it may have preferable network capacity performance, but its distribution side
Shown in formula such as Fig. 1 (1)-(2), time slot discretization that burst service is occupied with demand distribution service, on the one hand, be not easy to SMAC into
Row resource management, on the other hand, master controller need the structure of time slot of present frame being broadcast to terminal, the time slot point of discretization
Very long field is occupied with mode table, while also increasing the difficulty of burst service selection time slot.
The control signaling of satellite network is separated with business transmission, i.e., control signaling passes through control via control plane management
Transmission processed, business pass through traffic channel transmission via user plane management.This mode transmission reliability is high, but right
In star (for example, synchronous satellite propagation delay time 270ms) for the big satellite network of propagation delay time, when being obtained by three-way handshake
The time cost of gap resource pool nearly 1s, has seriously affected end-to-end time delay performance.

Long message then distributes resource pool according to message length, and carries and be sent to terminal A in message ACK-ResGT；
Short message then starts reception content Data；It receives, message ACK is sent to terminal A；
If (b) detection is not sent to the message of master controller, start to disappear to the initiation of next terminal according to polling list polling table
Cease Poll；
(24) it is designated as 0 if be properly received, detection messages transmit indication field, are carried out at the same time the combination of retransmitting message content：
If detection has the message for being sent to master controller, message length indication field is judged；
Long message then distributes resource pool according to message length, and carries and retransmitting message ACK-ResGT-Data/ACK-ResGT-
Terminal A is sent in ResGT；
Short message, then start to receive Data contents, receive, and sends message ACK to terminal A, while carrying re-transmission message
ACK-Data/ACK-ResGT；
If TPollTime-out does not receive message ACK/NACK, then NPoll+ 1, continue poll terminal A, maximum wrap count
Interrogating call does not have response, then it is assumed that the terminal off-grid carries out off-grid processing；
After terminal A receives message ACK/ACK-ResGT/ACK-ResGT-Data/ACK-ResGT-ResGT, stop timer
TReqGT/TDataJudge whether there is resource pool instruction information:
(25) if so, memory resource pool location information；
(26) if not provided, not making any processing.
If TReqGTOr TDataTime-out does not receive the message combination of message ACK and any ACK, then cannot actively send out again
The business of rising.
