Abstract

The invention relates to a scheduling management method based on field multi-measure wireless communication route equipment. The multi-measure wireless communication route equipment is a wireless communication system device integrating wireless self-organized network communication, CDMA/GPRS/3G (Code Division Multiple Access/General Packet Radio Service/The 3rd Generation Telecommunication) mobile wireless network communication, an MCU (Microprogrammed Control Unit), a video session terminal and a global positioning satellite module. The wireless self-organized network communication is a multi-channel network, can be rapidly erected and removed. The distance among all nodes is in a local area network with radius of not more than 5 kilometers, and the band width can reach 50Mbit/s. The CDMA/GPRS/3G is used as a standby network. The occupation conditions of all channels are different during the communication. The network occupancy rate of all channels can be detected in a real-time manner. The communication can be scheduled in a real-time manner to balance the occupancy rate of all channels. When the wireless self-organized network is accidentally interrupted, the route scheduling management enables the communication to be automatically switched to the CDMA/GPRS/3G network. As the band width of the mobile wireless network is small, a small amount of important data only can be transmitted. The route scheduling management detects whether the wireless self-organized network is restored in a real-time manner, if yes, the route scheduling management enables the communication to be switched to the wireless self-organized network from the CDMA/GPRS/3G mobile wireless network communication immediately. The whole system has high stability and high reliability.

Description

Schedule management method based on scene many means radio communication route equipment

Technical field

The present invention relates to each communication channel of on-the-spot many means radio communication route change system dispatching management in use, make each channel occupancy balance in the whole wireless network, guarantee that the communication data throughput is maximum, it is minimum to make that the network service blocking probability drops to.

Background technology

Internal radio communication generally adopts the base station mode at present, carries out the place of radio communication at needs and sets up middle base station, and all terminal accessing-points all must intercom through middle base station mutually, and this is just very high to the requirement of base station; If break down in the base station, the wireless network in the base station institute compass of competency will be paralysed, and just transmit the communication scheduling management that respectively accesses terminal the base station; Only each communication channel is carried out simple dispatching management; The schedule management method that uses is nearest routing channel principle, as long as calculate the nearest routing channel that the source end arrives destination, no matter whether occupancy is very high on this passage; And new communication request is appended on this channel; Through the channel idle that regular meeting has, the phenomenon that the channel that has blocks up very much, whole wireless network service efficiency is very low; In addition, this network more flexible is also very low, can not set up whenever and wherever possible and remove, and construction cost is high, and the cycle is long.

The problem that the object of the invention is exactly each channel occupancy imbalance in the time of will solving wireless LAN communication, throughput is low, reliability is low, set up and remove difficulty, expense is high.

Summary of the invention

Compare with above-mentioned prior art, each channel occupancy balance, high-throughput, high reliability when the invention provides a kind of cordless communication network communication based on many means radio communication route equipment, conveniently set up and remove, the wireless communication routing scheduling management method of low expense.

The present invention provides a kind of schedule management method based on many means radio communication route equipment; Many means radio communication route equipment is a collection from organizing wireless communication, the communication of CDMA/GPRS/3G mobile wireless network, MCU, video conference terminal, global positioning satellite is a kind of high integrated of one, high performance wireless communication system devices;

From the group wireless communication is multichannel network service; Can set up fast from the group wireless network; Remove fast; Each euclidean distance between node pair is not more than 5 kilometers local area network (LAN) at radius, and its bandwidth can reach 50Mbit/s, but transmitting multi-path video data and multi-path audio-frequency data and other data of several above that;

The CDMA/GPRS/3G mobile wireless network is as its backup network;

In communication process, the situation that the takies difference of each channel, the network usage of each channel of detecting real-time, Real-Time Scheduling communication makes the occupancy balance of each channel, reaches whole network service efficient and utilization rate optimum state;

When causing ad-hoc network to interrupt for a certain reason, the routing scheduling management automatically switches to the CDMA/GPRS/3G mobile wireless network with communication;

The CDMA/GPRS/3G mobile wireless network is as the backup of wireless ad hoc network;

Each channel communication occupancy is calculated in the management of wireless communication routing scheduling in real time; The current occupancy of each channel is set up a table, and wireless communication routing scheduling management real-time servicing and this table of renewal make this table embody each channel seizure ratio of current wireless network; When each communication request arrives; Nearest route is searched in the management of wireless communication routing scheduling, with all channel orderings, at first in ordering, in each channel occupancy counting rate meter, searches the minimum channel of occupancy by nearest route backward in the past; Give this communication request with this channel allocation; Constantly guarantee each channel communication balance of wireless network, reduce even avoid wireless network to block up, improve the wireless communication reliability.

Embodiment

The CDMA/GPRS/3G mobile wireless network is as its backup network;

The above embodiment; The present invention embodiment a kind of more preferably just; Common variation and replacement that those skilled in the art carries out in technical scheme scope of the present invention; On the basis of technical scheme of the present invention, allly all should be included in the protection range of technical scheme of the present invention change and the equivalents that particular carries out according to the principle of the invention.
