The working process of the method of the present invention is clearly and in detail described below by way of examples, and the embodiments are not intended to limit the scope of protection of the embodiments of the present invention.

Example 1

Applying the device of the embodiment of the present invention to a framework network composed of one or more video monitoring systems 3 is a schematic diagram of a system architecture of an embodiment of the present invention. As shown in FIG. 3, the video surveillance network is composed of one or more video monitoring systems and devices that implement dynamic access of the mobile front unit, and each video monitoring system includes one or more MPUs, wherein the MPU is added The MPU of the SIM card and the device for dynamically accessing the mobile front unit are composed of the obtaining unit 200, the generating unit 201 and the dynamic access unit 202. The obtaining unit 200 adopts signaling to collect signaling information of the SIM card in the MPU in the video monitoring system, and obtains information about the current location area code and the cell identifier of the SIM card by acquiring corresponding signaling information of one or more MPUs, thereby obtaining the MPU. The location of the base station.

The generating unit 201 generates location state information of the MPU according to the location information of the MPU and the first monitoring area of the first VSS and the second monitoring area corresponding to the one or more second VSSs;

Here, it is assumed that the VSS currently accessed by the MPU is the first VSS, and the other VSSs in the network are the second VSS. The location status information of the MPU may include: moving out from the first VSS and accessing the MPU location information in the first VSS. Matching position status information of the second VSS,

The preset unit in the device presets a first monitoring area of the first VSS and a second monitoring area corresponding to the one or more second VSSs. The above location status information of the MPU is generated by setting a geolocation filter (GeoFilter).

When the MPU enters or moves out of the first monitoring area of the first VSS, the dynamic access unit 202 triggers the action to send the location status information to the corresponding second VSS platform. The second VSS platform finds the corresponding MPU by multicast, and then accesses the MPU to the second VSS platform; if the location status information is removed from the first VSS, the first VSS also finds the corresponding MPU in a multicast manner. It is then removed from the first VSS (ie, it is logged out of the first VSS). By introducing the apparatus of the present embodiment in the system architecture, dynamic access of the MPU is very easy to implement in the VSS network. In practical applications, the apparatus of the embodiment of the present invention and the first VSS and the second VSS also need to perform necessary settings, for example, VSS performs the following settings in the apparatus of the embodiment of the present invention:

Service provider (SP, Service Provider) opens an account. For the device of this embodiment, each VSS is equivalent to its SP, so it is necessary to perform initial setting (SP account opening) for each VSS, and information such as SP identifier, SP password, URL for acquiring location information and location status information, and the like.

After opening an account, each VSS is an independent SP in the device of this embodiment, so the VSS monitoring area is equivalent to configuring a GeoFilter of the SP; on the other hand, for VSS, the MPU enters and leaves the monitoring. Zone, so the filter is configured to enter and exit The location status information is triggered only when the GeoFilter is triggered;

All MPUs in the video surveillance system network have their own Mobile Subscriber Directory Number (MDN) numbers, which need to be connected to the white list of the one or more account-opening SPs in the device of this embodiment, such that VSS Only the location information of these numbers, that is, the MPU, can be received.

4 is a schematic diagram of an MPU dynamically accessing VSS according to an embodiment of the present invention, as shown in FIG. 4,

Step 400: Perform SP account opening and configuration;

When the MPU-1 (1 is the number of the MPU and is distinguished from the MPU-2) enters and moves out of the first monitoring area of the first VSS, the first VSS can receive the information including the MDN, the location, and the like sent by the implementation apparatus;

Step 401: Determine, according to the MDN and the location information, the location status information by the GeoFilter to be: removed from the first VSS;

Step 402: The first VSS sends, by using a multicast mode, a message that is removed from the first VSS by the MPU-1 in the first VSS system, to perform logout of the MPU-1.

403a, MPU-1 receives the message removed from the first VSS, and unicasts the logout request to the first VSS;

403b. The MPU-2 receives the message that the MPU-1 is removed from the first VSS, and determines that the message that is removed from the first VSS is not for itself, and discards the multicast message.

Step 404: The first VSS receives the logout request of the MPU-1 on the Internet, and after performing the logout, moves out from the first VSS.

Step 405: The first VSS unicast mode sends the MPU-1 to complete the logout message to the MPU-1;

In this embodiment, if the location status information is: when the first VSS is reserved, the processing may not actually be performed.

Similarly, when the second VSS that matches the MPU location information receives the access MPU, the second VSS that matches the MPU location information performs the MPU access through the multicast mode, that is, the first match with the MPU location information. The second VSS is registered.

Optional,

Step 406, determining, by the GeoFilter, the location status information is: accessing the second VSS;

Step 4070, the MPU-2 receives the second VSS multicast MPU-1 registration notification;

Step 4071: The MPU-2 determines that the registration notification is not for itself, discards the multicast message, and does not perform any processing;

Step 4080, the MPU-1 receives the second VSS multicast MPU-1 registration notification;

Step 4081: The MPU-1 sends a unicast registration request to the second VSS.

Step 4082: The second VSS receives the registration request sent by the MPU-1, and completes the registration request processing of the MPU-1.

Step 4083, the second VSS accesses the MPU-1.
