Description
Technical field
The present invention relates to the link selection technology in a kind of integrated communication system, more particularly, to a kind of integrated communication system
In adaptive link system of selection.
Background technology
In recent years, the situation of fast development, new technology, new standard, the radio communication of New System is presented in wireless communication technology
Network is emerged in an endless stream, and military/police wireless communication technology is also greatly developed therewith, and communication support ability has obtained greatly carrying
Rise.However, while wireless communication technology constantly upgrades, also brought to military/police wireless communication technology new
Challenge, often there is that a variety of different wireless communication means coexist, the old and new's Wireless Telecom Equipment coexists in same internal institution, no
Consideration of the same Wireless Telecom Equipment due to aspect coexists with regard to shortcoming at the beginning of design, therefore, it is difficult to interconnect.This is not only right
Communication support personnel propose higher requirement, also bring serious electromagnetic interference problem.Therefore, integrated communicaton system in recent years
The design and foundation of system, it has also become military/police radio communication supportability of lifting and the study hotspot of efficiency.
Numerous different wireless communication means can be passed through software environment and hardware device by existing integrated communication system
It is integrated on unified platform, commanding is operated using the software interface on foreground, can be to all kinds of different channel radios
Letter equipment carries out unified scheduling and management, so as to realize the interconnection and interflow between all kinds of different Wireless Telecom Equipments.
Therefore, integrated communication system is commonly used for military/police command dispatching system at present.
During using existing integrated communication system organizing communication, user can only learn available communication link, without knowing
The current channel status of available communication link is how, when user initiates communication request (such as command centre is wireless with certain
When communication terminal is communicatively coupled), available communication is manually selected on the software interface of integrated communication system by operator
Link, conventional communication link include ultrashort wave link, short-wave link, digital colony network, satellite communication link etc..Due to thing
First the current channel quality of these available communication links is not known how, so if the available communication link currently selected
Failure, then can only once be selected, untill successful connection again again.Operator can only often rely on when being selected
The working experience of itself, not only connects into that power is relatively low, and the channel status of communication link is during business is transmitted
Time-varying, the communication link that business selects at the beginning of initiating is likely to become poor in business is carried out, and causes serious error code
Influence, therefore, the mode of this artificial selection communication link is given there is the problem of efficiency is low, communication quality is difficult to ensure that
The implementation of radio communication guarantee brings serious consequence.
The content of the invention
The technical problems to be solved by the invention are to provide the adaptive link system of selection in a kind of integrated communication system,
It can effectively improve communication link efficiency of selection, and can effectively improve communication quality.

Local evaluation value of the communication link under k-th of fuzzy criterion, em,kInitial value be m rows kth arranges in Φ element
Value；
6. utilize ε-greedy search strategies, randomly choose an available communication link or the global assessed value of selection it is maximum can
Communication link, selected available communication link is set as m*The available communication link of bar；Then m is utilized*Bar
Available communication link carries out business transmission；Wherein, the probability for randomly choosing an available communication link is small probability ε, choosing
The probability for selecting the maximum available communication link of global assessed value is maximum probability 1- ε, m*∈[1,M]；
7. judge whether business transmission has terminated after the T seconds, if it has ended, then waiting the request of business transmission next time；If not
Terminate, then calculate m*The true assessed value of the available communication link of bar, is designated as Then basisMore
New m*Local evaluation value of the available communication link of bar under each fuzzy criterion, by m*The available communication link of bar is in kth
Local evaluation value under individual fuzzy criterionUpdated value be designated as
Then makeStep is returned again to 3. to continue executing with；Wherein, 0 ＜ T≤1,Represent m*The available communication link of bar
The bit error rate, α represent learning rate,Represent m*Normalization of the available communication link of bar under k-th of fuzzy criterion
True value,In "=" be assignment.
2. the adaptive link system of selection in a kind of integrated communication system according to claim 1, it is characterised in that institute
The step of stating 3. inWherein, max () is to take max function, C1,C2,…,
Cm,…,CMThe channel disturbance of the corresponding channel interference values for representing the 1st article of available communication link, the 2nd article of available communication link
Value ..., the channel interference values of the m articles available communication link ..., the channel interference values of the M articles available communication link.
3. the adaptive link system of selection in a kind of integrated communication system according to claim 1 or 2, it is characterised in that
Described step 4. _ 1 in take d1=0.2, d2=0.4, d3=0.6, d4=0.8, d5=1.
4. the adaptive link system of selection in a kind of integrated communication system according to claim 3, it is characterised in that institute
The step of stating 4. _ 3 in
5. the adaptive link system of selection in a kind of integrated communication system according to claim 4, it is characterised in that institute
The step of stating 6. in take ε=20%.
6. the adaptive link system of selection in a kind of integrated communication system according to claim 5, it is characterised in that institute
The step of stating 7. in take α=0.1.
