Multimedia terminal adapter and remote connection method thereof

Abstract

The invention discloses a multimedia terminal adapter, which comprises a judgment module, a query module, a storage module, a transmission module, a receiving module and a control module, wherein the judgment module judges whether a voice over Internet protocol call is a remote connection request or not; the query module queries Internet protocol addresses of the multimedia terminal adapter and aplurality of pieces of second communication equipment, and corresponding relationships between the Internet protocol addresses and user ports; the storage module receives query results from the querymodule, and stores the query results in an Internet protocol address list and a corresponding relationship list respectively; the transmission module transmits the Internet protocol address list to first communication equipment; the receiving module receives the Internet protocol address selected by the first communication equipment; and the control module queries and makes accessible the user port corresponding to the Internet protocol address selected by the first communication equipment. The multimedia terminal adapter queries the Internet protocol address of the second communication equipment and makes accessible the corresponding user port to respond the remote connection request of the first communication equipment so as to meet the needs of remote control.

Description

technical field [0001] The present invention relates to network communication, in particular to a multimedia terminal adapter (MTA) and a remote connection method thereof. Background technique [0002] Remote control has become a major theme of network development, and the concept of network home is also based on this. In the remote control operation, the controlling party needs to know the Internet protocol (Internet protocol, IP) address of the controlled party in order to connect. However, dynamic IP addresses are mostly used in the current network, so it is difficult for the controller to query the IP address of the controlled party, so remote control cannot be realized. [0003] A common solution is for the accused to use a static IP address or connect to a dynamic domain name server (dynamic domain name server, DDNS). However, using a static IP address will have great security risks, and connecting to DDNS requires complex operations and long waiting times for connec...
