Description

Multimedia terminal adapter and method for remote connection thereof

The present invention relates to network communication, and in particular, to a multimedia terminal adapter (MTA) and a method for connecting the same at the remote end.

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 controller needs to know the host's Internet Protocol (IP) address to connect. However, in today's networks, dynamic IP addresses are often used, so it is difficult for the controller to query the IP address of the controlled party, so remote control cannot be implemented.

A common solution is to use the static IP address or connect to the dynamic domain name server (DDNS). However, using static IP addresses presents a significant security risk, and connecting to DDNS requires complex operations and lengthy connections and query latency.

In view of the above, it is necessary to provide a multimedia terminal adapter (MTA) for implementing a remote connection between the first communication device and the plurality of second communication devices, so as to meet the needs of remote control.

In addition, a method for remote connection is needed to implement a remote connection between the first communication device and the plurality of second communication devices, so as to meet the needs of remote control. .

The multimedia terminal adapter in the embodiment of the present invention is configured to implement a remote connection between the first communication device and the plurality of second communication devices, where the multimedia terminal adapter includes a processor, a network voice module, a user, and a judgment module. Groups, query modules, storage modules, and send modules. The network voice module receives the network voice call of the first communication device. The plurality of users are connected to the plurality of second communication devices and correspond to the network protocol addresses of the plurality of second communication devices. The judging module judges whether the network voice call is a remote connection request. The query module is configured to query a network protocol address of the multimedia terminal adapter and the plurality of second communication devices when the determining module determines that the remote connection request is determined, and query a network protocol address and a plurality of users of the plurality of second communication devices. The corresponding relationship of 埠. The storage module saves the network protocol address of the multimedia terminal adapter and the plurality of second communication devices as a network protocol address list, and saves the correspondence between the network protocol address of the plurality of second communication devices and the plurality of user devices as Correspondence list. The sending module sends the network protocol address list to the first communication device, so that the first communication device selects a network protocol address of the second communication device to be connected according to the network protocol address list. The receiving module receives a network protocol address of the second communication device selected by the first communication device. The control module queries the user relationship corresponding to the network protocol address of the selected second communication device in the correspondence list, and opens the queried user 埠.

The remote connection method in the embodiment of the present invention is applied to a multimedia terminal adapter having a processor, configured to implement a remote connection between the first communication device and the plurality of second communication devices, and includes the following steps: providing a plurality of users埠And connecting to the plurality of second communication devices and corresponding to the network protocol address of the plurality of second communication devices; receiving the network voice call of the first communication device; determining whether the network voice call is a remote end a connection request; if yes, querying a network protocol address of the multimedia terminal adapter and the plurality of second communication devices connected thereto, and querying a correspondence between a network protocol address of the plurality of second communication devices and a plurality of user terminals; The network protocol address of the adapter and the plurality of second communication devices is saved as a network protocol address list, and the correspondence between the network protocol address of the second communication device and the user node is saved as a correspondence relationship list; Addressing the address list to the first communication device, so that the first communication device selects a network protocol address of the second communication device to be connected according to the network protocol address list; and receives the first communication device in the network protocol address list The selected network protocol address; query and open the user corresponding to the selected network protocol address in the corresponding relationship list.
