An interconnection method, apparatus, and system where a remote Socket invocation client component obtains information about a first socket application programming interface Socket application programming interface (API) function invoked by a service client; encapsulates the information about the first Socket API function to a message structure; and sends the message structure, so that a remote Socket invocation server executes a second Socket API function corresponding to the first Socket API function in the message structure. The interconnection method, apparatus, and system solve the problem of an interconnection on a public network between the service client on a first local area network and a service server on a second local area network.
