Network interworking method, network element, and system

A network interworking configuration network element, comprising:

• a non-transitory memory storage comprising instructions;
• and
• a processor in communication with the non-transitory memory storage, wherein the processor executes the instructions to:
• determine that a first network is requesting to connect to a second network, and
• send, to a first network element in a first network element set, a first identifier of a second network element in a second network element set, the second network element corresponding to the first network element in the first network element set;
• send, to the second network element in the second network element set, a third identifier of the first network element in the first network element set;
• send, to a third network element in the first network element set, a second identifier of a fourth network element in the second network element set, the fourth network element corresponding to the third network element in the first network element set, the first network element set comprising network elements in the first network, the second network element set comprising other network elements in the second network, and each network element in the first network element set having a one-to-one correspondence to a corresponding network element in the second network element set;
• and
• send, to the fourth network element in the second network element set, a fourth identifier of the third network element in the first network element set.

A network interworking system, comprising:

• at least one network element in a first network;
• at least one network element in a second network;
• and
• a network interworking configuration network element comprising at least one processor and a non-transitory memory storing computer codes which, when executed by the at least one processor, cause the network interworking configuration network element to:
• determine that the first network is requesting to connect to the second network;
• send, to a first network element in a first network element set, a first identifier of a second network element in a second network element set, the second network element corresponding to the first network element in the first network element set;
• send, to the second network element in the second network element set, a third identifier of the first network element in the first network element set;
• send, to a third network element in the first network element set, a second identifier of a fourth network element in the second network element set, the fourth network element corresponding to the third network element in the first network element set, the first network element set comprising network elements in the first network, the second network element set comprising other network elements in the second network, and each network element in the first network element set having a one-to-one correspondence to a corresponding network element in the second network element set;
• and
• send, to the fourth network element in the second network element set, a fourth identifier of the third network element in the first network element set.
