Background technology
In recent years, the important way that wireless access wide band technology makes operator that wireless access technology is inserted as future development owing to its characteristics that insert the access capability of means, high bandwidth, low-cost fast adaptation new business market flexibly, thereby obtained developing rapidly.Because frequency resource is deficient relatively, the scientific research personnel of research WiMAX access technology is devoted to the resource management aspect mostly, wherein, channel allocation is again of paramount importance a kind of RRM mode, the fixed allocation mode can guarantee service quality, but ample resources is depleted in assigning process; Therefore dynamic assignment mode efficient height, and can make full use of resource becomes the numerous researchers' of industry research direction, but still the problem that exists is that the mutual interference of wireless channel phase and illegal wireless channel are not resolved always between the base station.
Summary of the invention
The objective of the invention is at above-mentioned existing problems and deficiency, providing a kind of effectively intercepts radio signal on every side, wireless signal is analyzed, discerned and handles, avoid wireless channel phase mutual interference between the base station, and wireless channel adaptive configuring method in the wireless broadband access system of the existence of elimination illegal wireless channel.
Technical scheme of the present invention is achieved in that and adopts dynamic radio channel to intercept technology, by wireless signal around the statistics, according to wireless signal frequency distribution, select processing method, and provide result of calculation, make transmitting base station can in time perceive the environmental change of radio signal on every side, seek the wireless channel and the emission mode that are fit to the work of this transmitting base station.Specifically comprise the steps:
(1), at first allow the base station power up startup, carry out initialization;
(2), the base station enters sense mode, the radio signal around intercepting, and radio signal analyzed and discern, but the operating position and the noise condition of each channel in detection and the record working channel;
(3), radio signal is good on every side when detecting, when having the good operation condition, select any one noise condition best and use rational idle channel automatically as working channel; Automatically write down the wireless channel of selecting, and be delivered to configuration manager; Automatically the channel according to memory carries out wireless signal transmission; When system's power down occurring, restart or when radio environment changes, returning step (2) on every side;
(4), wireless environment has the illegal wireless signal of telecommunication when detecting on every side, perhaps having channel that irrational transmitter is set exists, systems soft ware gives a warning and requires to select whether to proceed adaptive configuration, if select to proceed adaptive configuration, earlier with the illegal wireless radio equipment user solution of holding consultation, then select a noise condition the best and use rational idle channel as solving, shield this illegal channel as working channel; If do not select to proceed adaptive configuration, then carry out user's manual configuration, and carry out radio transmission according to user's configurating channel; When system's power down occurring, restart or when radio environment changes, returning step (2) on every side;
(5), when detecting radio signal complexity on every side, when perhaps not having idle channel, then carry out following steps: according to the detecting result, select to disturb minimum wireless channel, when the detecting result satisfies launching condition, the wireless channel that automatic record has been selected, and be configured in the hypervisor, carry out wireless signal transmission according to memory channel automatically at last; When system's power down occurring, restart or when radio environment changes, returning step (2) on every side; When the detecting result does not satisfy launching condition, adjust transmitting power, return step (5.1).
The present invention is owing to adopted above-mentioned wireless channel adaptive configuring method, radio signal by the carrier sense surrounding environment, and handle respectively after these signals are analyzed identification, thereby prevented that effectively wireless channel interferes with each other between the base station, discern and prevent the invasion of illegal wireless channel, make the adaptively selected and configuration of wireless trade energy, optimize channel resource and use; Guaranteed the service quality of wireless network, can be accurately the geographical position of signal have been positioned, the variation of wireless signal and select the channel and the transmitting power of suitable our station work around in time monitoring.The present invention can solve difficulties of wireless construction, provides strong technical guarantee for safeguarding wireless network and technical support.
The present invention is further illustrated below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the method flow diagram of adaptive configuration of the present invention.
Embodiment
As shown in Figure 1, the present invention is a wireless channel adaptive configuring method in a kind of wireless broadband access system, implements as follows:
(1), the base station powers up startup, carries out initialization;
(2), the base station enters sense mode, by the radio signal around the carrier sense, and radio signal analyzed and discerns, but the operating position and the noise condition of each channel in detection and the record working channel.Adopt the wireless signal in the RF working band scope of software filter selection base station, whether identify is the signal of interference signal, adjacent base station again, and these wireless signals are recorded suitable position, as the foundation of the own working frequency points of follow-up selection (wireless channel).
(3), radio signal is good on every side when detecting, when having the good operation condition, installing first or in spacious zone as the base station, there is not the radio transmission signal on every side, working band does not have unrecognizable interference source, when not having the microwave interference band, there is idle channel, automatically select any one noise condition the best and use rational idle channel as working channel, automatically write down the wireless channel of selecting, and being delivered to configuration manager, the channel according to memory carries out wireless signal transmission automatically.When system's power down occurring, restart or when radio environment changes, returning step (2) on every side;
(4), wireless environment has the illegal wireless signal of telecommunication when detecting on every side, perhaps peripheral base station is to the use of channel when unreasonable, systems soft ware gives a warning and requires to select whether to proceed adaptive configuration: if select to proceed adaptive configuration, then select a noise condition the best and use rational idle channel as solving, shield illegal channel as working channel; If do not select to proceed adaptive configuration, then carry out user's manual configuration, and carry out radio transmission according to user's configurating channel; When system's power down occurring, restart or when radio environment changes, returning step (2) on every side;
(5), complicated or when not having idle channel when detecting on every side radio signal, when being near city or microwave station or the high-tension bus-bar as the base station, perhaps peripheral base station is more, can't find a spendable idle channel, then need further to analyze and detecting, carry out following steps again:, select to disturb minimum wireless channel according to the detecting result; When the detecting result satisfies launching condition, the wireless channel that automatic record has been selected, and be configured in the hypervisor, carry out wireless signal transmission according to memory channel automatically at last, when system's power down occurring, restart or when radio environment changes, returning step (2) on every side; When the detecting result does not satisfy launching condition, adjust transmitting power, return step (5.1).
