Information Transmission Method and System, and Convergence Gateway

A convergence gateway, wherein the convergence gateway is deployed in a first network, wherein the first network is coupled to a second network using the convergence gateway, and wherein the convergence gateway comprises:

• a memory storing instructions;
• a communications interface;
• and
• a processor coupled to the memory and the communications interface, wherein the instructions cause the processor to be configured to:
• receive, using the communications interface, a service request from a first user equipment, wherein the service request comprises identity information of the first user equipment and service information of the first user equipment;
• obtain first user permission information of the first user equipment in the first network according to the identity information of the first user equipment;
• determine, based on the first user permission information, a forwarding manner for forwarding the service information to a second user equipment, wherein the forwarding manner comprises any one of the following manners:
• directly forwarding the service information to the second user equipment using the convergence gateway;
• or
• forwarding the service information to the second network using the convergence gateway, and forwarding the service information to the second user equipment using the second network;
• and
• send, using the communications interface based on the forwarding manner, the service information to the second user equipment.

An information transmission method, wherein the information transmission method is applied to a first network, and the information transmission method comprises:

• receiving, by a convergence gateway, a service request from a first user equipment, wherein the convergence gateway is deployed in the first network, wherein the first network is coupled to a second network using the convergence gateway, and wherein the service request comprises identity information of the first user equipment and service information of the first user equipment;
• obtaining, by the convergence gateway, first user permission information of the first user equipment in the first network according to the identity information of the first user equipment;
• determining, by the convergence gateway based on the first user permission information, a forwarding manner for forwarding the service information to a second user equipment, wherein the forwarding manner comprises:
• forwarding the service information to the second network using the convergence gateway;
• and
• forwarding the service information to the second user equipment using the second network;
• and
• sending, by the convergence gateway based on the forwarding manner, the service information to the second user equipment.
