The method, device and system provided by the present invention will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

Fig. 2 is a detailed flow chart of the sensor network information sending method provided by the embodiment of the present invention, specifically including:

Step S201, the sensor devices in the sensor network report the sensor network information to the management terminal to which they belong. The sensor network information can be control management information or data information collected by it. In order to meet the requirements of the information application platform for data According to the requirements of information use, the sensor network information also includes the location information of the sensor device.

In the embodiment of the present invention, the sensor device reports the sensor network information to the management terminal, using the communication protocol of the sensor network, specifically various private wireless communication protocols used in the sensor network in the prior art, here No more detailed description.

Step S202, after receiving the sensor network information reported by the sensor device, the management terminal in the sensor network sends the sensor network information to the information application platform through a wired network, wherein the wired network can be various fixed broadband wired networks , Such as asymmetric digital subscriber loop ADSL (AsymmetricDigitalSubscriberLine) network, cable TV cable CABLE network or fiber optic network and other fixed broadband wired networks.

In this process, the management terminal first sends the sensor network information to the wired gateway.

In the embodiment of the present invention, it is necessary to manage the ability of the terminal to transmit information using the communication protocol of the wired network. Therefore, in order to facilitate the use of existing network equipment in the prior art, preferably, it is proposed to use the home base station in the mobile communication network as the Management terminal.

Femtocell is a scalable, multi-channel, two-way communication micro-power wireless base station, mainly for indoor environments such as family residences or enterprises, and is connected to the operator's core network through a fixed broadband wired network. The emergence of femtocells extends traditional communication base stations to indoor environments, and has the advantages of high speed and low power in supporting indoor integrated services.

Based on the above inherent functions of the home base station, in the embodiment of the present invention, the home base station can be equipped with the function of managing the communication between the terminal and each sensor device in the sensor network, so that the home base station can manage each sensor device under its jurisdiction, That is, it can receive the sensor network information reported by the sensor device. Specifically, this step can be realized by integrating the M2M module in the home base station, so that it has the function of providing sensor device access, and has the function of mutual conversion between the communication protocol of the sensor network and the communication protocol of the wired network. Different communication protocols are used to receive and forward sensor network information.

When the home base station is used as the management terminal, the home base station first sends the sensor network information to the home base station gateway.

In the embodiment of the present invention, based on the characteristics that the home base station is connected to both the mobile communication network and the wired network, the following processing scheme can be further provided for the transmission of sensor network information:

When the sensor network information is the location information of the sensor device, since the location information reported by the sensor device may be integrated in the sensor device, the fixed location information carried by the sensor device will be reported when the sensor device moves. The location information of the sensing device is no longer its current accurate location information, so the location information needs to be corrected to obtain the current accurate location information of the sensing device.

The embodiment of the present invention proposes to solve this problem that the home base station can also determine its own location information, integrate its own location information with the location information of the sensor device, and send them to the information application platform, and the information application platform Receive the location information of the home base station and the location information reported by the sensor device, and judge the accuracy of the location information reported by the sensor device, so as to use other sensor network information reported by the sensor device more accurately and in a targeted manner, such as Various data information collected.

The femtocell may also correct the location information of the sensing device according to its own location information after determining its own location information, specifically as follows:

First, determine its own coverage area according to its own location information and its own coverage radius, and when it is determined that the location information reported by the sensor device exceeds the coverage area of the home base station, it is determined that the location information reported by the sensor device is inaccurate , the reported location information needs to be corrected, and it can be determined that the location information within the coverage of the home base station is the corrected location information of the sensing device. Randomly determine the position information within the coverage area as the corrected position information of the sensor device; the position information of the home base station can also be used as the corrected position information of the sensor device; more accurately, the home base station and the sensor device can When communicating, the direction and distance between the sensing device and the home base station are calculated by using the setting algorithm through the transmission power, transmission direction, and signal energy loss of the communication signal, and then the corrected position of the sensing device is accurately determined. location information.

After the home base station corrects the location information of the sensor device, it no longer sends the location information reported by the sensor device to the information application platform, but sends the corrected location information of the sensor device to the information application platform.

Preferably, the home base station can also integrate its own location information and the determined corrected location information of the sensing device, and send them to the information application platform.

The home base station determines its own location information, specifically in the following manner:

The first method: the home base station determines the location information of the macro base station of the cell according to the ID information of the cell where it is located, and determines its own location information according to the location information of the macro base station of the cell; specifically, it can be between the home base station and the When the macro base station communicates, the direction and distance between the macro base station and the home base station are calculated by using the setting algorithm through the transmission power, transmission direction, and signal energy loss of the communication signal, and then accurately determined according to the location information of the macro base station. output your location information.

The second method: the home base station determines its own location information through global positioning; specifically, by loading the GPS module in the home base station, in the GPS signal coverage area, you can directly obtain its own longitude, latitude and altitude through the global positioning system Altitude location information.

The third way: the home base station determines the location information corresponding to the IP address according to the IP address of the wired network allocated by the home base station as its own location information. Since the fixed broadband wired network assigns IP addresses to network devices based on geographical location, that is, each IP address has corresponding location information, so the femtocell can determine its own location according to its assigned IP address information.

Step S203. After receiving the sensor network information sent by the management terminal (ie, the home base station), the wired gateway (ie, the home base station gateway) forwards the sensor network information to the information application platform in the core network.

Step S204, after receiving the sensor network information, the information application platform processes or uses the sensor network information as required.
