Abstract
The invention discloses an automatic selection method of a wireless channel. A system picks a control channel and a business channel in all the channel at random when the system is started. All the channels need to accept a strength detection within the first scanning period and the quality of the channels need to be ranked in sequence according to the detection results. A channel of the best quality in the ranked channels is chosen to replace an old control channel to act as a new control channel, and the secondary channel is chosen to replace an old traffic channel and to act as a new traffic channel. After a period of time, the system jumps to a second scanning period and conducts the strength detection of all the channels again, and ranks the quality of all the channels in sequence according to the detection results, and then chooses the channel of the best quality in the ranked channels to be the new control channel and the secondary channel to be the new traffic channel. The above-mentioned procedures can be repeated to obtain the chosen channels to be the best all the time. By means of the automatic selection method of the wireless channel, a channel of good strength can be chosen accurately and quality of the channel can be guaranteed.
Description
Technical field
The present invention relates to the method for channel hopping in a kind of radio communication, relate in particular to a kind of wireless channel automatic selecting method.
Background technology
Because the channel quality of control channel is extremely important for the normal operation of whole wireless communication system, therefore in prior art, the not saltus step of control channel frequency causes control channel can't guarantee to be in the second best in quality channel always, make the antijamming capability of control channel be weaker than Traffic Channel, seriously be disturbed thereby control channel may occur under extreme case the situation that the communication that causes Traffic Channel can't normally be carried out at all.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, a kind of wireless channel automatic selecting method is provided.Accurately the good channel of selection intensity, guarantee communication quality.
In order to solve the problems of the technologies described above, the embodiment of the present invention provides a kind of wireless channel automatic selecting method, comprises the following steps:
When beginning, system gets a control channel and Traffic Channel at random in all channels;
Within the first scan period, all channels are carried out intensity detection, be arranged in order according to the quality of testing result with described all channels;
Select the old control channel of top-quality channel replacing as new control channel in channel after arranging, the replacement old service channel of next is as new Traffic Channel;
After certain interval of time, system jumped to for the second scan period, and all channels are re-started intensity detection, and was arranged in order according to the quality of testing result with described all channels;
Select top-quality channel as new control channel in channel after arranging, the channel of next is as new Traffic Channel.
The recuperation above-mentioned steps makes selected channel always for best.
Implement the embodiment of the present invention, accurately the good channel of selection intensity, guarantee communication quality.
Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
When beginning, system gets a control channel and Traffic Channel at random in all channels;
Within the first scan period, all channels are carried out intensity detection, be arranged in order according to the quality of testing result with described all channels;
Select the old control channel of top-quality channel replacing as new control channel in channel after arranging, the replacement old service channel of next is as new Traffic Channel;
After certain interval of time, system jumped to for the second scan period, and all channels are re-started intensity detection, and was arranged in order according to the quality of testing result with described all channels;
Select top-quality channel as new control channel in channel after arranging, the channel of next is as new Traffic Channel.
The recuperation above-mentioned steps makes selected channel always for best.
Above disclosed is only a kind of preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
