In order to reduce the number of probes required by the upper layer support system, the embodiment of the invention adds at least one interface convergence device as shown in fig. 2, and each interface convergence device is connected with the upper layer support system upwards through one probe and is connected with two or more lower layer network management systems downwards. And the interface convergence device sends the message from the upper layer support system to the lower layer network management system. And sending the message from a certain lower layer network management system to the upper layer support system, or packing the messages of the same type from a certain lower layer network management systems into a message and sending the message to the upper layer support system. Therefore, the communication between the upper layer supporting system and the lower layer network management system can be completed only by a small number of probes, the probe cost is saved, and the network structure is simplified.
The following describes in detail a communication method, an interface convergence device, and a communication system of a support system and a network management system according to an embodiment of the present invention with reference to the accompanying drawings.
An embodiment of the communication method of the present invention, as shown in fig. 3, includes:
s101, the interface convergence device obtains the identification of two or more lower-layer network management systems connected with the interface convergence device.
The identifier of the lower layer network management system can be actively collected by the interface convergence device or actively reported by the lower layer network management system.
S102, the interface convergence device receives information from a lower layer network management system.
S103, the interface convergence device adds the identifier of the lower layer network management system for sending the information in the information from the lower layer network management system, and sends the information added with the identifier to an upper layer support system through a probe.
In the embodiment, at least one interface convergence device is adopted, and each interface convergence device connects one probe with two or more lower-layer network management systems, so that the number of required probes is reduced, and the probe cost paid by an operator can be reduced.
In another embodiment of the communication method between the support system and the network management system of the present invention, a scenario applied in this embodiment may be a south interface in a communication interface, or a north interface, or other communication interfaces (mainly one-to-many interfaces) to which an interface convergence technique may be applied, as shown in fig. 4, including:
s201, the interface convergence device obtains the identification of two or more lower layer network management systems connected with the interface convergence device.
The lower layer network management system comprises: a lower network element management system or a lower network management system.
S202, the interface convergence device receives information from an upper layer support system, and sends the information from the upper layer support system to a lower layer network management system corresponding to an identifier according to the identifier of the lower layer network management system carried in the information from the upper layer support system.
The interface convergence device receives information from the upper layer support system, where 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 identification of the target lower layer network management system. And the interface convergence device sends 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 convergence device receives the information from the lower layer network management system.
The information from the lower layer network management system can be the call response of the lower layer network management system to the upper layer support system, and can also be the information actively reported by the lower layer network management system.
S204, the interface convergence device adds the identifier of the lower layer network management system which sends the information in the received information, and sends the information added with the identifier to the upper layer support system through the probe.
If the message sent downward by the upper layer support system in step 202 is a single resource object query message, or an operation instruction such as modify/delete/configure/deploy/activate/create, etc., then only a single lower layer network management system is targeted (only the identifier of the lower layer network management system to be executed in the message or instruction), although the message or instruction is sent to each lower layer network management system in a broadcast form, only the lower layer network management system corresponding to the identifier will respond.

Since a plurality of lower layer network management systems sharing one interface convergence device send messages to an upper layer support system, the interface convergence device is required to identify the lower layer network management system sending the message in each message sent to the upper layer support system, so that the upper layer support system can identify the messages. If the interface convergence device packs the same type of messages from some lower layer network management systems into one message to be sent to the upper layer support system, the identifier of each lower layer network management system sending the message needs to be added in the packed message respectively. The identifier of each lower layer network management system must be unique, and the identifier may be an independently set identification code, or an existing identifier, such as an ID number of each lower layer network management system, may also be borrowed. Therefore, the embodiment can complete the communication between the upper layer supporting system and the lower layer network management system only by a small number of probes, thereby saving the probe cost and simplifying the network structure.

S307, the interface convergence device has the function of responding to the calling request of the upper-layer support system, then sends the calling request to the lower-layer EMS, adds an EMS identifier for data fed back by the lower-layer EMS, and finally returns the integrated result to the upper-layer support system.
When processing the request of the upper layer support system, the interface convergence device decides to send the request to the EMS corresponding to the EMS identifier by analyzing the EMS identifier;
when the interface convergence device processes the response of the lower EMS layer, the received return data from the lower network management system is added with the EMS identifier for encapsulation, then a plurality of responses encapsulated with the EMS label are integrated, and the integrated return data is reported to the upper support system through the probe.
