Detailed ways

In the existing telecom operation and maintenance system, it is necessary to connect the system through the upper-level support system and the lower-level network management system to complete service provisioning and inventory query. The communication architecture of the upper and lower systems of the existing telecom operation and maintenance system is shown in Figure 1. The upper support system and each lower network management system are connected through a probe, and the probe is used to complete the connection between the upper support system and the lower network management system. transfer of information between them. Probes are generally provided by independent software vendors in the form of components, and independent software vendors charge value-added charges based on the number of probes. As more and more lower-level network management systems are connected to the upper-level support system, the number of probes also increases. This will not only increase the probe fee that the operator needs to pay, but also make the entire network more complicated, which is not conducive to the overall maintenance of the network.

In order to reduce the number of probes required by the upper support system, the embodiment of the present invention, as shown in Figure 2, adds at least one interface convergent, and each interface converger is connected upwardly with the upper support system through a probe, and downwardly with two One or more lower-level network management systems are connected. The interface converger sends messages from the upper-layer support system to the lower-layer network management system. Send messages from a certain lower-level network management system to the upper-level support system, or package messages of the same type from several lower-level network management systems into one message and send it to the upper-level support system. In this way, only a small number of probes can complete the communication between the upper support system and the lower network management system, which saves the cost of probes and simplifies the network structure.

The communication method, interface converger, and communication system between the support system and the network management system of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

An embodiment of the communication method of the present invention, as shown in Figure 3, includes:

S101. The interface converger obtains the identifiers of two or more lower-layer network management systems connected to the interface converger.

The identifier of the lower-layer network management system may be actively collected by the interface converger or actively reported by the lower-layer network management system.

S102. The interface converger receives information from the lower-layer network management system.

S103. The interface convergent adds the identifier of the lower-layer network management system sending the information to the information from the lower-layer network management system, and sends the information added with the identifier to the upper-layer support system through the probe.

This embodiment adopts at least one interface convergent, and each interface convergent connects a probe with two or more lower-layer network management systems, which reduces the number of probes required and can reduce the cost of probes paid by the operator. Needle fees.

Another embodiment of the communication method between the support system and the network management system of the present invention, the application scenario of this embodiment may be the southbound interface in the communication interface, or the northbound interface, or other communication interfaces that can apply the interface convergence technology (mainly is a one-to-many interface), as shown in Figure 4, including:

S201. The interface converger acquires the identifiers of two or more lower-layer network management systems connected to the interface converger.

The lower-layer network management system includes: a lower-layer network element management system or a lower-layer network management system.

S202. The interface converger receives the information from the upper-layer support system, and sends the information from the upper-layer support system to the lower-layer network management system corresponding to the identifier according to the identifier of the lower-layer network management system carried in the information from the upper-layer support system system.

The interface converger receives information from the upper-layer support system. The information from the upper-layer support system may be an instruction from the upper-layer support system to the lower-layer network management system, such as a call request from the upper-layer support system to the lower-layer network management system. The information carries the identifier of the target lower-layer network management system. The interface converger delivers the information to the lower-layer network management system corresponding to the identifier according to the identifier of the lower-layer network management system carried in the information.

S203. The interface converger receives information from the lower network management system.

The information from the lower-layer network management system may be a call response from the lower-layer network management system to the upper-layer support system, or may be information actively reported by the lower-layer network management system.

S204. The interface converger adds the identifier of the lower-layer network management system sending the information to the received information, and sends the information with the identifier to the upper-layer support system through the probe.

If the message sent down by the upper layer support system in step 202 is a single resource object query message, or an operation instruction such as modification/deletion/configuration/deployment/activation/creation, it is only aimed at a single lower layer network management system (only The identifier of the lower-layer network management system to be executed), although the message or instruction is sent to each lower-layer network management system in the form of broadcast, only the lower-layer network management system corresponding to the identifier will respond. The interface converger adds the identifier of the lower-layer network management system that sent the information to the response information, and sends the information with the identifier to the upper-layer support system through the probe.

If multiple lower-level network management systems report information, or the message sent downward by the upper-level support system in step 202 is a multi-resource object query message, causing multiple lower-level network management systems to report query results, the interface converger receives two or more For the same type of information from different lower-level network management systems, the interface converger adds the identification of the lower-level network management system that sends the information to each message, and will add two or more information of the same identification from different lower-level network management systems Pack it into a message and send it to the upper support system through the probe.

The messages of the same type refer to messages with the same structure, and the structure may be a known message structure such as List, Map, and Vector. The interface converger merges these structurally consistent messages into one message for reporting.

In this embodiment, step 202 may also be placed before step 201, and the step 202, step 201, step 203, and step 204 are not in a necessary order.

In this embodiment, the interface converger broadcasts the message from the upper-layer support system to each lower-layer network management system. Send messages from a certain lower-level network management system to the upper-level support system, or package messages of the same type from several lower-level network management systems into one message and send it to the upper-level support system. Since multiple lower-layer network management systems sharing one interface converger send messages to the upper-layer support system, the interface converger needs to identify the lower-layer network management system that sent the message in each message sent to the upper-layer support system, so that the upper-layer support system can identify it . If the interface converger packs messages of the same type from several lower-layer network management systems into one message and sends it to the upper-layer support system, it needs to add the identifier of each lower-layer network management system that sends the message to the packaged message. The identifier of each lower-layer network management system must be unique, and the identifier can be an independently set identification code, or can also borrow an existing identifier, such as the ID number of each lower-layer network management system. In this way, this embodiment only needs a small number of probes to complete the communication between the upper-layer support system and the lower-layer network management system, which saves the cost of probes and simplifies the network structure.

Yet another embodiment of the communication method between the support system and the network management system of the present invention, the application scenario is the southbound interface in the communication interface, the upper support system is the OSS system, and the lower network management system is the EMS as an example, and the identification of the lower network management system adopts each The ID number of the lower-level network management system, the specific steps are as shown in Figure 5, including:

S303. The interface converger publishes its own converged object.

The interface converger registers itself on the name space server or saves its own address in other ways, so that the probe can find its own objects.

S304. The upper support system is connected to the interface convergent through the probe.

S306. The interface converger provides a mechanism for maintaining session connections.

The interface converger provides a mechanism for maintaining the dialogue connection. On the premise of ensuring the validity of the upper-level support system session, it always maintains the normal session connection with the lower-level EMS.

S307. The interface converger has the function of responding to the call request of the upper-layer support system, then sends the call request to the lower-layer EMS, adds an EMS identifier to the data fed back by the lower-layer EMS, and finally returns the integrated and processed result to the upper-layer support system.

When processing the request of the upper support system, the interface converger decides to send the request to the EMS corresponding to the EMS identifier by analyzing the EMS identifier;

When the interface converger processes the response of the lower-layer EMS, it adds the received return data from the lower-layer network management system to the EMS label for encapsulation, and then integrates the multiple responses encapsulated with the EMS label, and uses the probe to return the integrated The data is reported to the upper support system. Wherein, the returned data of the lower-layer network management system uses the ID number of the lower-layer network management system as the EMS identifier, and the integrated returned data includes the ID numbers of each lower-layer network management system.

S308. The interface converger has the function of monitoring and sending the lower layer network management event report.

In this embodiment, an interface converger combined with a probe is used to connect the upper support system with two or more lower network management systems, which reduces the number of probes required and reduces the cost of probes paid by operators.
