[0086] Specific application example 2:
[0087] The management platform defines faults or abnormal events as follows:
[0088] Event B: Illegal movement. This event applies to the location of the wireless sensor network terminal when the terminal user signs up. Such as vending machine monitoring settings, parking lot monitoring equipment, etc.
[0089] Relevant parameters for determining event B: contracted location information, which is a location range, expressed in latitude and longitude coordinates (X1-X2, Y1-Y2), where X1 is less than X2, and Y1 is less than Y2.
[0090] The corresponding processing method: deny terminal access, or reduce the resources provided to the terminal, or perform detachment of the terminal.
[0091] 2. The management platform sends the events to be monitored, related parameters, or/and processing methods after the events occur to the wireless sensor network gateway.
[0092] 3. The wireless sensor network gateway monitors and detects the connected wireless sensor network terminal according to the parameters related to the received event. The event detection method is as follows:
[0093] 3.1. If each wireless sensor network terminal includes a GPS positioning module, the location information can be used as part of the request signaling when requesting access, where the location information is the longitude and latitude coordinates (X, Y) of the terminal. When the wireless sensor network gateway receives the request, it determines whether the location information (X, Y) in the access request is within the range defined by the event-related parameters. The specific method for determining is to compare whether the longitude X of the terminal is in the event-related parameters. Between X1 and X2, and compare whether the latitude Y of the terminal is between Y1 and Y2 of the event-related parameters. If the value of X is less than X1 or greater than X2, or the value of Y is less than Y1 or greater than Y2, then the location of the terminal is considered Beyond the defined range, the terminal is determined to be an illegal move.
[0094] 3.2. When the wireless sensor network terminal requests access for the first time, the wireless sensor network gateway saves its location information (Xa, Ya). In the subsequent access of the terminal, the terminal still needs to include the current location information (Xb, Yb) in the access request, and the wireless sensor network gateway can compare the location information (Xb, Yb) in the access request with the previous Whether the location information (Xa, Ya) of one access matches, the specific comparison method is whether Xb is greater than or equal to Xa-m and less than or equal to Xa+m, and whether Yb is greater than or equal to Ya-m and less than or equal to Ya+m, where m It is the position statistical error margin value, indicating that the position deviation within this range is acceptable, and the management platform or the user server does not update its position information, it is judged as an illegal movement.
[0095] 4. Once the wireless sensor network gateway detects an illegal movement of a wireless sensor network terminal, it will report the failure or abnormal event to the management platform. The report content includes: the occurrence of the failure or abnormal event: event B (illegal movement) , Wireless sensor network terminal identification: WSN_UE_ID, or/and the time when the fault or abnormal event occurs: 2010-5-27 10:48, or/and the place where the fault or abnormal event occurs: latitude and longitude coordinates or wireless sensor gateway identification WSN_GW_ID ; Or when the gateway has locally received the corresponding processing method for the event sent by the management platform, it performs the operation according to the processing method, that is, denies the terminal's access, or reduces the resources provided to the terminal, or executes the terminal Deattach.
[0096] 5. After receiving the report sent by the wireless sensor network gateway, the management platform can send the corresponding processing method of the event to the wireless sensor network gateway.
[0097] 6. The wireless sensor network gateway performs operations according to the corresponding processing method of the received event, that is, denies the terminal's access, or reduces the resources provided to the terminal, or performs detachment of the terminal.

[0104] Send a detection message to the wireless sensor network terminal 33, and set a timer T. After the wireless sensor network terminal 33 receives the detection message, it receives the feedback message sent by the wireless sensor network terminal 33. If the timer T expires, If no feedback message is received, it is determined that the wireless sensor network terminal 33 is malfunctioning or abnormal; or,
[0105] Or set a timer T, and start the timer T when the monitoring starts. If no signaling or data from the wireless sensor network terminal 33 is received when the timer T expires, it is determined that the wireless sensor network terminal 33 is malfunctioning or Abnormal; or,
