Description

An information transmission addressing method for 5G communication network equipment

technical field

The invention relates to the technical field of network communication, and in particular, to an information transmission addressing method for 5G communication network equipment.

Background technique

In order to support various services such as roaming and inter-office handover during networking of communication network devices, it is necessary to support the interconnection between devices. However, at present, the core network devices of the public network mainly use the No. 7 signaling for information transmission and addressing between devices. The No. 7 signaling network consists of signaling points, signaling transfer points, and signaling links connecting them. In the No. 7 signaling network, a communication network node whose signaling point is equipped with a common-path signaling system includes a source node and a destination node. A signaling transit point is a signaling transit node that passes signaling messages from one signaling link to another signaling link. The signaling link connects various signaling points and signaling transfer points, and is a physical link used to transmit signaling messages. Its SCCP layer protocol defines GT (Global Identification Code) and SSN (Subsystem Number) on the basis of MTP layer definition of PC.

SCCP can perform flexible routing according to the combination of PC, SSN and GT to decide the reception or forwarding of No. 7 signaling messages between core network devices. The SIGTRAN protocol stack defines a series of adaptation layer protocols, which are divided into four layers: IP protocol, signaling transmission, signaling transmission adaptation, and signaling application. In the IP network era, the application of No. 7 signaling must be based on the SIGTRAN protocol stack.

However, using the No. 7 signaling method for information transmission and addressing costs a lot. On the one hand, it is because, as mentioned above, its transport layer cannot be directly carried over IP, and must undergo signaling adaptation and conversion. On the other hand, the No. 7 signaling based on traditional circuit switching is too complicated and redundant. When the number of signaling points and addresses increases, the number of signaling links will increase sharply, and it cannot adapt to the IP-based core network.

FIG. 3 is a flowchart of an information transmission addressing method for a 5G communication network device applied for by the present invention. Steps S301-S307 are included.

Step S201: The TCP encapsulation layer receives the TCP layer message.

By extending the TCP/IP protocol stack, a TCP encapsulation layer and a signaling adaptation layer are added between the transport layer and the application layer of the TCP/IP protocol stack. Among them, the TCP encapsulation layer defines signaling point codes for network element devices. The signaling point codes correspond to IP addresses and port numbers, and adopts a unified coding method for the entire network. The TCP encapsulation function module realizes the whole network through the signaling point codes. NE device addressing within the network. The signaling adaptation layer is the application layer of TCP encapsulation. When the source device cannot obtain the destination signaling point code, it translates the global code of the device's network-wide unique number into the signaling point code, and then converts the signaling point code according to the signaling point code. Messages are sent to their destinations through pre-defined routes.

Step 302: Determine whether the destination signaling code in the TCP encapsulation header is equal to the source signaling point code of the current device. If the destination signaling code is equal to the source signaling point code, perform step S304. If the destination signaling code is not equal to the source signaling code For point coding, step S303 is executed.

Find out whether there is a corresponding TCP connection in the preconfigured link set, and if so, send a TCP layer message to the searched link, and the message is routed successfully. If not, judge whether there is a default link, if there is a default link, send the TCP layer message to the default link, otherwise discard it.

Wherein, sending the TCP layer message to the default link specifically includes: the signaling transfer point receives the TCP layer message, and if it is determined that the destination signaling point code is not equal to the current device signaling point code, then according to the pre-configured link set Search for a TCP connection. When a connection corresponding to the signaling point code is found, the TCP layer message is sent to the connection, and the message is routed successfully.

Step 303 : use the TCP encapsulation layer to send the message to other network element devices for processing.

Step 304: Determine the user type, and send the obtained TCP layer message to the signaling adaptation layer or service layer corresponding to the user type for processing.

When the TCP encapsulation layer of the current network element device receives the message of the TCP layer, it first determines whether the destination signaling point code in the TCP encapsulation header is equal to the source signaling point code of the current device. If it is determined to be equal, it indicates that the message is a message to be processed by the current device, the user type is determined, and the message is sent to the signaling adaptation layer or service layer corresponding to the user type for processing. If it is determined that they are not equal, it indicates that the message needs to be forwarded, and then the TCP encapsulation layer is used to forward the message to other network element devices.

Step 305: Determine whether the called user global code in the header of the signaling adaptation layer exists in the pre-configured local global code list, if it exists in the local global code list, perform step S307; if it does not exist in the local global code list , step S306 is executed.

Step S306 : use the signaling adaptation layer to send the message to other network element devices for processing.

According to different global code types, query routes in different global code routing tables. The routing table is pre-configured according to the global code planning, and saves the mapping relationship between the global code and the destination signaling point code.

If the corresponding mapping relationship is queried, change the destination signaling point code in the header of the TCP encapsulation layer to the destination signaling point code configured in the routing table, send a message to the TCP encapsulation layer, and then use the TCP encapsulation layer to send the message , the message is routed successfully.

If the corresponding mapping relationship is not queried, the message is sent through the default link.

Step S307: Send the message to the application layer.

When the signaling adaptation layer of the current device receives the message of the TCP layer, it determines whether the called user global code in the header of the signaling adaptation layer exists in the pre-configured local global code list. If it exists, it indicates that the TCP layer message If it needs to be processed by the current device, this message is sent to the application layer for processing. If it is judged that it does not exist, it indicates that the TCP layer message needs to be forwarded to other network element devices for processing, and the signaling adaptation layer is used to send the message.

In a possible embodiment, a unified message structure is adopted between each network element device, and the message structure includes the following five parts:

TCP/IP header;

HEADFLAG, indicating the beginning of the TCP encapsulation layer message;

TCP encapsulation header;

application layer messages; and

ENDFLAG, indicating the end of the TCP encapsulation packet.

In the embodiment of the application of the present invention, the TCP encapsulation layer and the signaling adaptation layer are added between the transport layer and the application layer of the TCP/IP protocol stack. When the devices communicate with each other, they do not need to be interconnected, and can also be switched through other devices, and these devices used for switching can also be service nodes themselves. Since the transfer can be performed according to the global code or the signaling point code, the service layer of the communication device also has the routing capability, and different routing strategies can be implemented according to different services. In addition, the interaction between the communication equipment and the device under test is simulated based on the network card. Compared with the tester that uses the integrated routing information protocol test function in the prior art to perform the routing information protocol test, the test port resources are rich, and there is no need for different manufacturers. Routers or Layer 3 switches are equipped with different testers, and only use ordinary computers or network cards, which are easy to operate and low in cost.

The notification of content change of the routing execution object may include: notification of property change of the routing execution object or notification of state change of the routing execution object, and the like. Among them, the status of the routing execution object refers to the running status of the routing execution object running the routing function, such as the network card is installed, the network card driver is not installed, etc.;

Step S402: According to the obtained routing information modification notification, determine the object model position of the routing execution object of the routing information modification in the database.

The object model of each routing execution object and the relationship between the object models are recorded in the database. The object model corresponds to object description information corresponding to the routing configuration information;

Step S403: Update the object model of the determined routing execution object.

According to the routing configuration information change notification, the object model of the routing execution object is created and deleted at the location, so that the object model of the routing execution object is updated at the location.

If the routing configuration information change notification is a routing execution object creation notification, a new routing execution object is created at the object model position of the routing execution object determined in the database, and the object description information of the created routing execution object is set to correspond to the routing configuration information . If the routing configuration information change notification is the routing execution object deletion notification, the original routing execution object is deleted at the object model position of the routing execution object determined in the database. If the routing configuration information change notification is the routing execution object content change notification, delete the original routing execution object at the object model position of the routing execution object determined in the database, and create a new routing execution object at the location in the database. The object description information of the route execution object corresponds to the route configuration information.

By creating and deleting the routing execution object in the database, the object description information of the object model of the updated routing execution object can be made corresponding to the routing configuration information recorded in the routing configuration information change notification. Synchronization of recorded routing information.
