This application claims priority to Chinese Patent Application No. 200710125729.1, entitled "A Communication Device and Its Application Method, System", filed on Dec. 29, 2007, the entire contents of In this application.

Technical field

The present invention relates to the field of communications, and in particular, to a communication device, an application method thereof, and a system.

Background technique

With the development of digital technologies and the improvement of living standards, the concepts of P2P, IPTV, VoIP and digital home are becoming more and more popular. The following briefly introduces each of the above concepts:

P2P (Peer To Peer): A peer-to-peer computing or peer-to-peer network, which refers to an application model that shares computer resources and services by directly exchanging between systems. The application of P2P systems in the Internet has become very common, mainly including file sharing classes, instant messaging classes, streaming media classes, shared storage classes, and peer computing applications. The P2P file sharing application mainly implements file transfer between peer-to-peer users based on the P2P network; the P2P instant messaging application mainly implements text, voice or video communication between peer-to-peer users; the P2P streaming media application mainly implements live broadcast of media based on the P2P network. On-demand or recording application; P2P shared storage application, mainly based on P2P network to achieve massive data storage and sharing, share storage; P2P peer-to-peer computing, mainly based on P2P network shared computing processing, make full use of the network to achieve the convergence of computing resources. Among them, file sharing class, instant messaging class and streaming media class belong to entertainment applications.

IPTV: Internet TV is a technology that utilizes the broadband Internet infrastructure to provide a variety of digital media services including TV programs and value-added services through Internet protocols using home TV as the main terminal. Video and audio services are the basic services of IPTV, among which live TV and video on demand are the most basic.

VoIP (Voice Over Internet Protocol) refers to the real-time transmission of voice over an IP network. The voice of the caller is sampled and digitized, compressed, and packaged by a special device or software. The voice is transmitted to the other party through the IP network, and the other party passes the special equipment or After the software receives the voice packet, it decompresses it and restores it to an analog signal. The application forms of VoIP include: communication between PC (Personal Computer, Personal Computer), communication between PC and telephone, and communication between telephones.

Digital Home: The digital home includes the following network entities: Netsau 4 Incoming Functional Entities, Home Network Functional Entities, and User Terminal Functional Entities. The network ^ breaks into the functional entity, which is mainly responsible for completing network access, QoS (Quality of Service) and security; The home network function entity needs to complete the home internal device network management and signaling media processing; the user terminal function entity is used directly by the user to provide user interface and service display.

In the prior art, there is a scheme for providing network content resources through a centralized dedicated server using a conventional network architecture. With this scheme, the download and playback of media resources can be supported, and voice communication is supported. However, this approach does not take full advantage of client resources, including computing resources, network resources, and storage resources. At the same time, if the number of users is large, the pressure on the dedicated server will be large, and support for a large number of users will be very difficult.

In the prior art, the acquisition of resources by using a single P2P application is realized, and the downloading and playing of media resources can be supported, and the scheme of supporting voice communication is supported. At present, P2P-based application software emerges one after another, but they are independent. Even for the same type of application (such as file download), there are many different systems, which cannot communicate with each other, and network resources are not fully utilized. For example, eMule and BT are two kinds of file downloading software, and resource sharing cannot be realized. Even if the user can select eMule or BT download on the PC, the user needs to judge which one to download, which is inconvenient for the user.

Since different network resources are in different P2P application systems, the quality of services that can be obtained is different. For example, file A shares the largest number of users in the P2P first network, while file B shares the largest number of users in the P2P second network. . If a single P2P application system is adopted, it is difficult to achieve full use of network resources.

At the same time, due to the complexity of the network content resource format, and digital home devices are gradually becoming more complicated, there are already mobile phones, PCs (PCs, STBs, Set Top Boxes), various game consoles (such as PSP). (Portable Handset, Play Station Portable), PS3 (PS3 Game Console, PLAYSTATION 3), MP3, MP4, PMP (Portable Media Player, Portable Media Player), Digital Photo Frame, Information Appliance (such as Streaming TV), etc. Interoperability and resource sharing between devices are becoming more and more important, but the inconsistency of various device support formats has become an obstacle to resource sharing.

The following description will be made in conjunction with specific examples. FIG. 4 is a schematic diagram of networking of a communication device application system according to an embodiment of the present invention. It includes a P2P network, a communication device A and its managed terminal devices, and a communication device B and its managed terminal devices. The communication device A can be separated into the device form of the RTU-A and the entertainment gateway A, and the terminal devices managed by the communication device A include PC-A, WIFI (Wireless Fidelity), Telephone-A and DMA-A. The communication device B can be separated into the device form of the RTU-B and the entertainment gateway B, and the managed terminal devices include PC-B, WIFI (Wireless Fidelity, Wireless). Fidelity) Phone-B and DMA-B.

For the file download service requested by the terminal device, for example, the PC-A needs to apply for the document file File-A, and initiates a data download request to the entertainment gateway. The entertainment gateway integrates multiple P2P clients, and can initiate a file request to different P2P networks, and find a file from it. The best P2P network to get the data. Once the specific information is obtained, the document File-A is returned to the requesting PC-A. Among them, selecting the best P2P network, that is, analyzing one or more of the data transmission rate on multiple P2P networks, the data transmission delay on multiple P2P networks, and the number of available users of multiple P2P networks, determine a performance. The best P2P network.

For the streaming service requested by the terminal device, for example, the on-demand service, the DMA-A initiates a play request to the entertainment gateway. At this time, the DMA-A needs to negotiate an audio-video encoding format with the entertainment gateway, and the entertainment gateway initiates an on-demand request to different P2P networks. Select one of the best network acquisition media. When the media resource is obtained, the media resource format may not meet the video format requirements of DMA-A, and need to be converted in the entertainment gateway, including media encapsulation and encoding format conversion. Among them, selecting the best P2P network, that is, analyzing one or more of the data transmission rate on multiple P2P networks, the data transmission delay on multiple P2P networks, and the number of available users of multiple P2P networks, determine a performance. The best P2P network.

For the instant messaging service requested by the terminal device, since the instant communication requires the selected peer to communicate, the peer selection can be unified through the entertainment gateway, for example, Sk pe (an instant messaging software) service can be unified through the entertainment gateway. Instead of installing the Skype client in each terminal device, each terminal device within the digital home can download a respective user list from the entertainment gateway and negotiate with the entertainment gateway a voice encoding format that the terminal device can support. After the entertainment gateway obtains the voice coded data sent by the peer end, the terminal device communicates with the entertainment gateway to obtain the voice coded data converted by the entertainment gateway, and initiates P2P communication with the peer end through the entertainment gateway. Wherein, if the data format received by the entertainment gateway is inconsistent with the data format supported by the terminal device, the gateway is responsible for completing the real-time conversion of the data format.

Since the P2P communication client is integrated in the entertainment gateway, the number mapping of the P2P network application can be edited according to the user name. For example, user A has the number N1 in the P2P first network, N2 in the P2P second network, and N3 in the P2P third, and Nl, N2, and N3 are the available numbers of user A. The terminal device managed by the entertainment gateway can be downloaded from the entertainment gateway to the number mapping list. When user A initiates a communication call to user B, the entertainment gateway finds the P2P network associated with user B and the corresponding connection number from the number mapping list, and initiates a connection with user B. If the multiple connection modes of user A and user B are valid, then a P2P network connection with the best network quality is selected for communication. If the quality of the network connected between user A and user B is unstable, when the effective bandwidth of a connection decreases or the data transmission delay increases, it can support automatic switching to other currently optimal P2P networks in the connection list. Among them, selecting the best P2P network, that is, analyzing one or more conditions of data transmission rate on multiple P2P networks and data transmission delay on multiple P2P networks, determines a P2P network with the best performance.

For the file query download service and the streaming media query on-demand service requested by the terminal device, the search of the resource can be searched by the keyword matching of the file name master, and other keywords such as actors, directors, formats, and the like can be attached. That is, the matching search can be performed based on the file name alone, and the matching search can be performed based on the file name + other keywords. The entertainment gateway performs matching search in different P2P networks, obtains resource sharing information (including file downloading and streaming media on demand), sorts available P2P networks according to the number of shared users, and preferentially obtains media from the P2P network with the largest number of shared users. Resources.

In summary, the application system of the communication device according to the embodiment of the present invention has multiple P2P clients integrated in the communication device, realizing automatic acquisition of optimal resources of the P2P network, and full use and sharing of network resources. Support various user service requests. At the same time, because the conversion unit is integrated in the communication device, the resource sharing obstacle caused by the non-uniform support format of the device is broken, and the network resource is fully shared on different devices. The spirit and scope of the Ming. Thus, it is intended that the present invention cover the modifications and variations of the inventions
