Below, in conjunction with Fig. 3, and, method embodiment of the present invention is described in detail, and specifically describes three kinds of above-mentioned functions with reference to Fig. 2.
In the network configuration stage, wireless senser control appliance 1 is according to the configuration information from NMS4, disposes each transducer that this wireless sensing control appliance 1 had jurisdiction over and can call the corresponding relation of the application service of these transducers.Also promptly, authorize application service can call which transducer.Certainly, this mapping relations are multi-to-multis, and also, a transducer can be called at the same time or separately by one or more application services; In addition, one or more wireless sensers can simultaneously or be called in an application service respectively.Usually, wireless senser control appliance 1 is placed on local side, also is in the machine room, therefore, can think that DSLAM equipment is safe.Therefore, in the mapping relations between storage application service and the wireless sensor node on the wireless senser control appliance 1 at local side, mean and to dispose the wireless sensing business on a large scale, and can not be subjected to the restriction of region.
In addition, wireless senser control appliance 1 also needs to determine QoS (Quality ofService, service quality) strategy.Certainly, QoS can corresponding with the type of application service, different type of service, pairing QoS difference; Perhaps, QoS also can be corresponding with concrete application service.These depend on the strategy of QoS.The concrete formulation of qos policy property related to the present invention is little, therefore, does not repeat them here.
At first, in step S10, the application service request message that wireless senser control appliance 1 receives from application server 2a.Comprise the type of the application service that application server 2a asks and title etc. in this application service request message.
Then, in step S11, wireless senser control appliance 1 is to sending inquiry request messages with the corresponding one or more related sensor A of this application service, also, and Query message.
The mapping table of this application service pairing one or more wireless sensers with it has prestored in wireless senser control appliance 1.Wireless senser control appliance 1 is searched this mapping table, and find out and the corresponding one or more wireless senser A of this application service, for example, with node identification (SensorID), MAC Address or the IP address of the corresponding one or more wireless senser A of this application service.Then, according to MAC Address or the IP address of one or more wireless senser A, wireless senser control appliance 1 unicasts to this one or more wireless senser A respectively with inquiry request message.This query messages is used to inquire about these one or more related sensor A and whether collects the sensing business datum that application server 2 is asked.In addition, in step S11, wireless senser control appliance 1 also is mapped to this application service request the QoS rule of appointment.Also promptly, this Query message that is sent to wireless senser also comprises the QoS sign, is used for identifying the transmission priority of this message at network transmission process.
