Description
Technical field
The present invention relates in satellite communication field technology for self-adaptively transmitting more particularly to it is a kind of based on business driving defending
Star communicates adaptive transmission method.
Background technique
With being constantly progressive for communication technology of satellite, business also develops towards the direction of diversification, in order to preferably be promoted
The adaptation ability of business and transmittability, all kinds of adaptive techniques are also assented and are given birth to, and mainly have the technologies such as adaptive coding and modulating.
Networking transmission system in satellite communication field, main system include TDMA system and FDMA system, and TDMA system is suitable for greatly
User volume networking is applied, and advantage is flexibly but efficiency is low compared with FDMA system, and FDMA system efficiency is relatively high to be suitable for using
Family is less, the stronger application environment of real time business.Mainly by time domain, frequency domain resource carries out division progress for the application of two kinds of systems
It efficiently utilizes, in order to better adapt to the demand of different business, resource should change, Cai Nenggeng with the changes in demand of business
User demand and the scheduling of Internet resources are adapted to well.
For the adaptive transmission method that will preferably be driven based on business, apply in satellite communication system, it is established that
The flexible dispatching of the time domain and frequency resource that are driven by business is highly important with distribution method.
Summary of the invention
Object of the present invention is to be promoted in satellite communication field, the utilization rate of time-domain and frequency-domain resource effectively combines two classes to provide
Advantage of the source in terms of business transmission, and the ability that business drives is introduced among system, establish the money based on business characteristic
Source distribution mechanism realizes the adaptive conversion capability of system.
The technical solution used in the present invention are as follows:
Satellite communication adaptive transmission method based on business driving, it is characterised in that include the following steps:
(1) it after sending terminal booting, is networked after searching network management channel by network management center；
(2) the business feature sensing module for sending terminal perceives the characteristic of business to obtain QoS of survice demand, and will
QoS of survice demand is reported to network management center；
(3) network management center is analyzed for QoS of survice demand, obtains time delay, shake and the speed in QoS of survice demand
Then rate distributes corresponding time-domain resource and frequency domain resource according to time delay, shake and rate in a network；
(4) send terminal using time-domain resource and frequency domain resource distribute as a result, when business to be mapped to the carrier wave of TDMA
Among gap, realization business is adapted to carrier slots；
(5) it sends terminal and starts business transmission module, the transmission of industry of going forward side by side business；
Complete the satellite communication Adaptive Transmission driven based on business.
Wherein, in step (2), the business feature sensing module for sending terminal is perceived to obtain business to the characteristic of business
QoS demand, specifically:
Characteristic perception module is by detecting different business, such as data, video, voice, using business recognition strategy library and
Service feature information bank carries out Classification and Identification for business, is mainly matched with the feature being stored in library, carried out simultaneously
Traffic management, final output sensing results, sensing results include time delay, shake, the rate requirement of business, these information are provided
To terminal, time-domain resource is carried out for link layer and frequency domain resource mapping provides reference frame.
Wherein, in step (3), corresponding time-domain resource and frequency domain resource are distributed in a network specifically:
If the QoS demand of business demand is promoted, the quantity of Time Slot Occupancy is promoted, until entire carrier slots are taken,
If not being able to satisfy business demand, it is switched on another high-speed carrier wave and is matched and mapped；, whereas if business is real
Shi Yaoqiu is reduced, then carrier slots quantity is reduced under the premise of meeting QoS demand, distributes to other users in net, realizes money
It shares in source.
It has the following advantages that compared with the background technology, the present invention
1. the satellite communication adaptive transmission method compared with prior art based on business driving, more can adapt to rear guard
The demand of diversification business in star communication system becomes more particularly to better adapt to the development of the whole network IP, is different from traditional volume
Code modulation self adaptive thinking, has arrived application and resource management layer for adaptive concept.
2. establishing with the ability of service-aware, the mode of time-domain resource and frequency spectrum resource unified distribution, improves resource shoulder to shoulder
Utilization rate establishes a kind of application system flexible from transport layer system angle, only by the characteristic of business to the management of resource into
Row driving.

Specific embodiment
In the following, the invention will be further described by Fig. 2, Fig. 3 in conjunction with Fig. 1.
Satellite communication adaptive transmission method based on business driving, it is characterised in that include the following steps:
(1) it after sending terminal booting, is networked after searching network management channel by network management center；
(2) the business feature sensing module for sending terminal perceives the characteristic of business to obtain QoS of survice demand, and will
QoS of survice demand is reported to network management center；
As shown in Figure 1, characteristic perception module is known such as data, video, voice using business by detecting different business
Other policy library and service feature information bank carry out Classification and Identification for business, mainly carry out with the feature that is stored in library
Match, while carrying out traffic management, final output sensing results, sensing results include time delay, shake, the rate requirement of business, will
These information are supplied to terminal, carry out time-domain resource for link layer and frequency domain resource mapping provides reference frame.
The specific steps of business feature sensing module workflow, as shown in Figure 2:
First to the data of input, the identification of physical port is carried out, can tentatively be classified to business by the step,
Then data link layer protocol is identified, network protocol identification, port identification, protocol identification, finally to service feature into
Row matching, output different business to time delay, shake, rate requirement finishing service characteristic perception module workflow, obtain industry
Business QoS demand.
(3) network management center is analyzed for QoS of survice demand, obtains time delay, shake and the speed in QoS of survice demand
Then rate distributes corresponding time-domain resource and frequency domain resource according to time delay, shake and rate in a network；
As shown in figure 3, before starting time-frequency resource allocating, business feature sense of the reception from business feature sensing module first
Know information, if QoS demand is constant, maintains original resource allocation policy；If QoS demand improves, increase time slot allocation
Quantity, being able to satisfy demand then terminates, and is unable to meet demand and is then switched to another high-speed carrier wave, re-starts time slot allocation, full
Sufficient QoS demand；Time slot allocation quantity is reduced if QoS demand reduces, realization resource is shared with other terminals.
(4) send terminal using time-domain resource and frequency domain resource distribute as a result, when business to be mapped to the carrier wave of TDMA
Among gap, realization business is adapted to carrier slots；
(5) it sends terminal and starts business transmission module, the transmission of industry of going forward side by side business；
Complete the satellite communication Adaptive Transmission driven based on business.
