A method includes: a user equipment (UE) obtains an address of a to-be-connected IoT gateway. An IoT cloud platform allocates, to a mobile application (MAPP) installed on the UE, a unique access identifier corresponding to the MAPP. The UE provides an address of the IoT cloud platform and the allocated access identifier for the IoT gateway whose address is already learned. The IoT gateway adds the access identifier to a registration message, and sends the registration message to the IoT cloud platform. The IoT cloud platform binds the IoT gateway to the MAPP corresponding to the access identifier included in the registration message, so as to complete access of the IoT gateway. ## Claims ### Claim 1 An access method, comprising: accessing, by a communication apparatus having a mobile application (MAPP) installed thereon, a local area network according to an operation of a user of the communication apparatus, wherein the local area network is of a gateway that includes a routing function;
