Although communication, such as wired, wireless, infrared, and optical, can be used, it is generally considered that short-range wireless low-power communication technology is most suitable for sensor networks. It is generally called Wireless Sensor Network (WSN). The widely used wireless low-power communication technologies include: IEEE 802.15.4 and Zigbee technologies.

WSN和电信网， 如 2G移动通信、 3G移动通信、 xDSL、 FTTx、 宽带 无线接入、 卫星 /微波等结合， 可以使 WSN作为现有网络的延伸， 扩展了 通信网络的能力， 使通信对象从人扩展到物理世界， 具有良好的发展前景。 WSN与现有的电信网络结合后， 可以使 WSN感知的数据有效的传递到数 据中心， 通过对数据的整理和分析， 可以极大程度的改变人类获取自然世 界的数据的方式， 同时也能够对 WSN进行集中的管理， 解决目前分散在各 处的 WSN难以管理的问题。 WSN and telecommunication networks, such as 2G mobile communication, 3G mobile communication, xDSL, FTTx, broadband wireless access, satellite/microwave, etc., can make WSN an extension of the existing network, extending the capabilities of the communication network, enabling communication objects from People have expanded into the physical world and have good prospects for development. When WSN is combined with the existing telecommunication network, the WSN-aware data can be effectively transmitted to the data center. By collating and analyzing the data, the way in which humans can obtain the data of the natural world can be greatly changed. WSN carries out centralized management, and the solution is currently dispersed in each The problem of WSN is difficult to manage.

WSN与电信网络结合， 是指将 WSN与电信网络相连接， 利用电信网 络对 WSN及其提供的业务进行监控、 管理及完成业务的承载与合作实施， 并通过电信网络扩展 WSN 所提供的业务。 WSN 和电信网的结合一般是 WSN通过网关设备连接至电信网平台。  The combination of WSN and telecommunication network refers to connecting the WSN with the telecommunication network, using the telecommunication network to monitor, manage and complete the service bearer and cooperation implementation of the WSN and the services it provides, and extend the services provided by the WSN through the telecommunication network. The combination of WSN and telecommunication network is generally that the WSN is connected to the telecommunication network platform through the gateway device.

WSN终端为构成 WSN的传感器节点， 负责釆集并上传数据， 以及接 收并执行命令， WSN终端一般通过一跳或多跳与网关连接， 组成 WSN的 设备少则几个多则几百个， 设备间可根据需要以星形、 树形或网状（mesh ) 等方式组网， 其中某些设备可能具有较强的组网和数据转发能力。 在 WSN 元实体， 电信网络中的有关网络单元实体通过网关将有关指令发送给 WSN 终端。 而且， 在 WSN釆用常用的 IEEE 802.15.4和 Zigbee技术时， 一般由 网关负责创建 WSN, 负责 WSN终端加入和离开传感器网络时的管理， 网 关中保存有 WSN 终端的配置信息和传感器网络的业务配置信息等重要数 据。  The WSN terminal is a sensor node constituting the WSN, and is responsible for collecting and uploading data, and receiving and executing commands. The WSN terminal is generally connected to the gateway through one or more hops, and the devices constituting the WSN are several hundreds or more.

In the WSN meta-entity, the relevant network element entity in the telecommunications network sends the relevant instructions to the WSN terminal through the gateway. Moreover, when the WSN uses the commonly used IEEE 802.15.4 and Zigbee technologies, the gateway is generally responsible for creating the WSN, which is responsible for the management of the WSN terminal when joining and leaving the sensor network. The gateway stores the configuration information of the WSN terminal and the service of the sensor network. Important information such as configuration information.

可以看出， 网关作为 WSN和电信网结合时的一个重要的设备， 决定着 WSN能否正常工作， 但是， 网关存在发生故障或者网关需要升级的情况， 目前， 在网关发生故障时， WSN终端不能将数据通过网关上报给网络侧的 有关业务单元实体， 而且， WSN中的终端配置信息和网络参数也可能因为 网关故障而丟失， 使 WSN本身也不能正常工作； 另外， 在将 WSN中的网 关进行设备更新时， 由于更换后的网关不具备之前传感器网络的配置信息， 从而需要更换后的网关重新加入 WSN终端来创建 WSN,在重新创建 WSN 成功之前， WSN业务无法正常进行， 从而会给 WSN业务的可靠性带来不 利的影响。 发明内容 It can be seen that the gateway acts as an important device when the WSN and the telecommunication network are combined, which determines whether the WSN can work normally. However, the gateway has a failure or the gateway needs to be upgraded. Currently, when the gateway fails, the WSN terminal cannot The data is reported to the relevant service unit entity on the network side through the gateway. Moreover, the terminal configuration information and network parameters in the WSN may also be lost due to the gateway failure, so that the WSN itself cannot work normally. In addition, the gateway in the WSN is performed. When the device is updated, the replaced gateway does not have the configuration information of the previous sensor network. Therefore, the replaced gateway needs to rejoin the WSN terminal to create the WSN. Before the WSN is successfully created, the WSN service cannot be performed normally, and the WSN service will be provided. The reliability has an adverse effect. Summary of the invention

有鉴于此， 本发明的主要目的在于提供一种无线传感器网络的管理方 法及系统， 能在网关发生故障或网关升级的情况下， 尽快恢复 WSN业务， 从而提高 WSN的稳定性及可靠性。  In view of the above, the main object of the present invention is to provide a management method and system for a wireless sensor network, which can restore the WSN service as soon as possible in the event of a gateway failure or a gateway upgrade, thereby improving the stability and reliability of the WSN.
