Description

Communication method, communication device and communication system Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method, a communications device, and a communications system. Background Currently, an operator network supports an active access of a peer device (e.g., a terminal, a base station, a server, etc.) to an off-hook device (e.g., a camera, a smart home device, etc.) of a gateway device (e.g., a customer premise equipment (customer premises equipment, CPE), a Mobile Station (MS), a routing device, etc.), so as to implement bidirectional communication between the off-hook device and the peer device. Because the down-hanging device is deployed in the intranet, the access mode is also called intranet penetration access to the down-hanging device. The opposite device is opposite to the hanging device, and the opposite device is also called an access device, a first device, an external device or the like. The down device is connected to the internet through the gateway device, so if the opposite terminal device needs to remotely access the down device of the intranet, the gateway device needs to perform pre-configuration for the down device, for example, configuration information such as internet protocol (internet protocol, IP) address and the like. At present, configuration information is generally written in advance on a gateway device by a person, and then the gateway device configures the hanging device based on the configuration information. However, this manual configuration is cumbersome, time consuming and error prone due to the large number of gateway devices. Disclosure of Invention The embodiment of the application provides a communication method, a communication device and a communication system, which are used for realizing automatic acquisition of intranet access configuration information by gateway equipment. In a first aspect, an embodiment of the present application provides a communication method, which may be applied to a session management device (also referred to as a communication device), where the session management device may be a session management network element, a module (e.g. a circuit, a chip, or a chip system, etc.) in the session management network element, or a logic node, a logic module, or software capable of implementing all or part of the functions of the session management network element. The session management network element may be, for example, a session management function (session management function, SMF) network element, a gateway control plane (gateway control plane, GW-C) network element, or other network element with session management function. The method comprises the steps of receiving request information from a gateway device, wherein the request information is used for requesting intranet access configuration information, the intranet access configuration information comprises an IP address field of a down-hanging device of gateway equipment, information of a private network which the gateway equipment requests to access and an IP address field of a peer-to-peer device which allows access to the down-hanging device, acquiring subscription data of the gateway equipment from a data management network element, acquiring the intranet access configuration information of the gateway equipment from an authentication server when a service type in the subscription data comprises intranet access service, and sending the intranet access configuration information to the gateway device. Based on the above scheme, the gateway device can send the request information for requesting the intranet access configuration information to the session management device, so that the session management device can send the intranet access configuration information to the gateway device based on the request information, thereby realizing automatic configuration of the intranet access configuration information for the gateway device, being beneficial to avoiding a series of problems (such as tedious, time-consuming and error-prone) caused by manually configuring the gateway device, and improving the accuracy and efficiency of configuration. As a possible implementation method, the sending the intranet access configuration information to the gateway device includes sending the intranet access configuration information to the gateway device if it is determined that the request information is received. Based on the above-mentioned scheme, only if it is determined that the gateway device requests to acquire the intranet access configuration information, the session management device transmits the intranet access configuration information to the gateway device, and if the gateway device does not request to acquire the intranet access configuration information, the session management device may not transmit the intranet access configuration information to the gateway device, so that signaling overhead
