The video monitoring system is an important component of a safety precaution system, and the video monitoring system is widely applied to multiple fields, such as the construction of safe cities, due to the advantages of intuition, convenience, rich information content and the like. In the field of, for example, safe city construction, a large monitoring system is usually configured as a multi-level and multi-domain monitoring system, for example, a video monitoring system of a country may include a country-level monitoring subsystem, a plurality of provincial-level monitoring subsystems, a plurality of city-level monitoring subsystems, and the like. In the national video monitoring system, a national monitoring subsystem may be set as an upper-level domain, each provincial monitoring subsystem may be set as a lower-level domain of the national monitoring subsystem, each urban monitoring subsystem may be set as a lower-level domain of the corresponding provincial monitoring subsystem, and so on.
The superior domain and each subordinate domain are used as relatively independent video monitoring systems, and sharing of video monitoring resources between domains can be achieved through an IP network. The subordinate domain can select which monitoring equipment resources accessed by the subordinate domain can be shared to the superior domain, and adopt an inter-domain synchronization protocol of a new national standard GB/T28181 standard to share the directory information of the monitoring equipment allowing resource sharing to the superior domain, wherein the directory information can comprise equipment codes, display names, address codes, authority function codes, father node address codes, activity states and the like of the monitoring equipment, and the superior domain can store the directory information shared by the subordinate domain in a locally stored directory database. When a user logs in a superior domain through a client, the superior domain can display a subordinate domain equipment list to the user according to a locally stored directory database, so that the user can conveniently and intuitively acquire related information of the subordinate domain, such as display names and quantity of subordinate domain access monitoring equipment, states of the monitoring equipment and the like.
However, with the continuous development of video monitoring systems, a million-scale monitoring device can be accessed in a lower domain, and if the above-described inter-domain synchronization protocol according to the new national standard GB/T28181 standard is still used, directory information of the monitoring device accessed in the lower domain is shared to an upper domain, in a sharing process, at most 10 entries of directory information can be carried by a NOTIFY message, so that the lower domain inevitably sends NOTIFY messages to the upper domain many times, which results in very low efficiency of sharing directory information from the lower domain to the upper domain, and since the upper domain receives a large number of NOTIFY messages, the upper domain bears a large pressure, and errors are easily caused in the process of updating a locally stored directory database according to the NOTIFY messages.
In order to improve the efficiency of sharing directory information from a lower domain to an upper domain, the application provides an inter-domain directory sharing method.
Please refer to fig. 1, which is a schematic view of an application scenario for implementing the inter-domain directory sharing method according to the embodiment of the present application, where fig. 1 includes: upper domain 11, lower domain 12, gateway 13 to gateway 1 n. The upper domain 11 may include a management server 111, a directory synchronization server 112, a database server 113, and signaling gateways 114 to 11 n; the lower domain 12 may include therein a management server 121, a directory server 122, and IPCs 123 to 12 n.
In the upper domain 11, the directory synchronization server 112 may establish a directory sharing channel with the directory synchronization server 122 in the lower domain 12 through the inter-domain directory sharing method provided by the present invention, and obtain the directory information that can be synchronized in the directory synchronization server 122 through the synchronization mechanism provided by the present application; after the directory synchronization server 112 obtains the directory information, the directory information may be sent to the database server 113, and the database server 113 may maintain a directory database; a user (not shown in fig. 1) can access the management server 111 through a client (not shown in fig. 1), and the management server 111 presents a directory list of monitoring devices that can allow resource sharing in the lower domain 12 to the user based on a directory database in the database server 113; the upper domain 11 can perform signaling interaction with the lower domain 12 through one signaling gateway from the signaling gateway 114 to the signaling gateway 11 n; it is understood that the lower domain 11 illustrated in fig. 1 is only an example, and in practical applications, other devices may also exist in the upper domain 11, and the present application does not limit this.
In the lower domain 12, a user (not shown in fig. 1) may access the management server 121 through a client (not shown in fig. 1) to configure monitoring devices, such as IPCs 123 to IPCs 12n, accessed in the lower domain 12, for example, to configure network addresses of the monitoring devices, whether resource sharing is allowed, and the like, and the directory management server 122 may be configured to manage directory information of the IPCs 123 to IPCs 12n, and may also push the directory information to the upper domain 11 through a synchronization mechanism provided in the present application.
It should be noted that fig. 1 only illustrates one lower domain, in practical applications, the upper domain 11 may correspond to a plurality of lower domains, and the upper domain 11 may perform signaling interaction with the plurality of lower domains through the signaling gateways 114 to 11n, which is not limited in this application.
It should be noted that, in the present application, when the upper domain 11 corresponds to a plurality of lower domains, each lower domain corresponds to only one signaling gateway in the upper domain 11, and specifically, based on what kind of consideration, the following description may be referred to, and the detailed description is not given herein.
In order to make the inter-domain directory sharing method provided by the present application clearly and intuitively understood by those skilled in the art, the following embodiments are listed for illustration.
Referring to fig. 2A, a flowchart of an embodiment of the inter-domain directory sharing method according to the present application is shown, based on the application scenario illustrated in fig. 1, where the method is applicable to the directory synchronization server 112 located in the upper domain 11 in fig. 1, and includes the following steps:
step 201: after sending a message for indicating successful registration to any one of the at least one subordinate domain, obtaining the directory information of the monitoring device allowing resource sharing in any one of the subordinate domains based on a preset synchronization mechanism, and storing the directory information in a locally stored directory database.
As shown in fig. 1, the subordinate domain 12 may send a Register message for registration to the superior domain 11 by using a Register method defined in RFC 3261, and after receiving the Register message, the superior domain 11 verifies registration information carried by the Register message to determine whether the subordinate domain that requires registration meets the registration condition, and if the registration meets the registration condition, registers the subordinate domain and sends a message indicating that the registration is successful to the subordinate domain.
In the present application, the synchronization mechanism may be configured in the upper domain 11 and the lower domain 12 in advance, and it should be noted that the synchronization mechanism configured in the upper domain 11 and the lower domain 12 may be the same. Taking the case that the lower domain 12 shares the directory information with the upper domain 11, after the upper domain 11 sends a message indicating that the registration is successful to the lower domain 12, the directory information of the monitoring device in the lower domain 12 that allows resource sharing may be obtained based on a preset synchronization mechanism.
In an alternative implementation, the synchronization mechanism may be a database synchronization mechanism. For example, a database synchronization system may be installed in the directory synchronization server 112 and the directory synchronization server 122 in advance, and after the lower domain 12 successfully registers with the upper domain 11, the database synchronization system may start a synchronization process, and the database synchronization system in the directory synchronization server 122 actively pushes directory information to the database synchronization system in the directory synchronization server 112; alternatively, the database synchronization system in the directory synchronization server 112 actively obtains directory information from the database synchronization system in the directory synchronization server 122.
It should be noted that, based on the database synchronization mechanism, the database synchronization system in the directory synchronization server 122 may send all directory information to the database synchronization system in the directory synchronization server 112 at a time, that is, the upper domain 11 may obtain the directory information of all monitoring devices allowing resource sharing in the lower domain 12 at a time based on the database synchronization mechanism.
In another alternative implementation, the synchronization mechanism may be an LDAP (Lightweight directory access Protocol) synchronization mechanism. LDAP is based on the TCP/IP protocol and is a protocol that can be used to publish directory information to many different resources. An LDAP database may be established in the management server 121 based on the LDAP protocol, and the LDAP database includes directory information of monitoring devices allowing resource sharing and accessed by the lower domain 12, and based on the LDAP synchronization mechanism, the lower domain 12 may transmit the directory information in the LDAP database to the upper domain 11 in batches, or transmit the directory information to the upper domain 11 at a time, that is, based on the LDAP synchronization mechanism, the lower domain 11 may acquire the directory information of all monitoring devices allowing resource sharing in the lower domain 12 in batches, or acquire the directory information of all monitoring devices allowing resource sharing in the lower domain 12 at a time.
In the present application, after acquiring the directory information of all monitoring devices allowing resource sharing in the lower domain 12, the upper domain 11 may store the directory information in a locally stored directory database, for example, in the directory database of the database server 113.
Step 202: receiving a notification message indicating that the directory information has changed, which is transmitted from any one of the lower domains.
In an alternative implementation, when the directory information of the monitoring device that allows resource sharing in the lower domain 12 changes, the "change" may include addition, deletion, modification, and the like of the directory information, for example, if a monitoring device that allows resource sharing is newly added in the lower domain 12, then the directory information of the monitoring device may be added in the directory information, and the lower domain 12 may send notification information indicating that the directory information changes to the upper domain 11 based on a preset time interval.
In another alternative implementation, the lower domain 11 may actively send a directory retrieval request to the lower domain 12 based on a preset time interval, for example, every 15 minutes, and the subsequent upper domain 11 may receive a notification message sent by the lower domain 12 according to the directory retrieval request to indicate that the directory information changes.
Step 203: and updating the directory database according to the notification message.
In addition, in this application, it should be further noted that, based on the synchronization mechanism provided in this application, when the lower domain 12 sends the directory information to the upper domain 11, the directory information does not pass through any signaling gateway from the signaling gateway 114 to the signaling gateway 11n, so that a gateway path required for signaling interaction between the upper domain 11 and the lower domain 12 cannot be established in the upper domain 11, and in order to implement subsequent signaling interaction between the upper domain 11 and the lower domain 12, in this application, a uniform format may be set for the device code included in the directory information of the lower domain, specifically, the device code of this application may carry the domain identifier of the lower domain to which the monitoring device belongs, for example, as shown in fig. 2B, which is an example of the device code format of this application.
Moreover, as can be seen from the above description, a lower domain corresponds to a signaling gateway, and in the present application, the corresponding relationship between the domain identifier and the signaling gateway identifier may be stored in the upper domain 11 in advance, for example, the following table 1 is an example of the corresponding relationship between the domain identifier and the signaling gateway identifier:
TABLE 1
| Domain identification | Signaling gateway |
| Lower domain | |
| 11 | |
| … | … |
A user (not shown in fig. 1) of the upper domain 11 may access the management server 111 of the upper domain through a client (not shown in fig. 1), and send a control instruction for acquiring any monitoring device, for example, a monitoring resource of the IPC113, to the management server 111, specifically, the control instruction may be used to request to acquire a real-time monitoring resource on the IPC113, or a monitoring resource of the IPC113 in a specified time period, and when the management server 111 detects the control instruction, the management server 111 may acquire a device code of the IPC113 from directory information of the IPC113 according to the control instruction, for example, as shown in fig. 2B, and then, a domain identifier of the lower domain 12 to which the IPC belongs 113 is obtained by parsing from the device code, for example, as shown in fig. 2B, the first 6 bytes of the device code are parsed, and the domain.
The management server 111 may continue to look up the corresponding relationship illustrated in table 1 according to the domain identifier, so as to obtain a signaling gateway identifier corresponding to the domain identifier of the domain, for example, "gateway 114", so that the management server 113 may send a resource acquisition request to the signaling gateway 114 according to the signaling gateway identifier "gateway 114", and perform subsequent interaction procedures by a signaling gateway (not shown in fig. 1) in the lower domain 12 and the corresponding IPC 113.
Up to this point, by setting a uniform format for device encoding and pre-storing the correspondence between the signaling gateway identifier and the domain identifier, communication between the upper domain 11 and the lower domain 12 can be achieved.
It can be seen from the foregoing embodiments that, by pre-configuring a synchronization mechanism in the upper domain and the lower domain, and based on the synchronization mechanism, the upper domain obtains the directory information of the monitoring device that allows resource sharing in the lower domain, thereby implementing directory sharing between the upper domain and the lower domain, and because based on the synchronization mechanism, the upper domain can obtain all directory information in the lower domain at a time or obtain directory information in the lower domain in batches, thereby improving the efficiency of sharing the directory information of the monitoring device from the lower domain to the upper domain.
