Problems solved by technology

The disadvantages of this scheme are: First, no matter what kind of wired technology is used, the coverage inside the home network must be limited by the number and position of the corresponding plugs in the home, especially the coaxial cable and the category 5 line socket, which are very large in number. Usually there are only 2 to 3 per family, and for many home network terminals, such as personal digital assistant (PDA: Personal Digital Assistant), digital compressed audio / video player (MP3 / 4), etc. Those who do not want to make a wired connection; the second is that the data transmission capacity is limited, and it cannot effectively support various high-speed service requirements of the future home network, such as the simultaneous transmission of multiple high-definition multimedia services, etc.
The disadvantages of this solution are: First, it is difficult to meet the coverage requirements inside the home network. Generally, the communication distance of short-distance wireless transmission technology is very limited, usually within 3 to 10 meters, and many houses are built with stone and concrete. , the communication capability will drop sharply due to the fading of the internal walls of the home, or even completely unable to communicate; second, the data transmission capability is very limited, and the peak rate generally does not exceed 54Mbps, which is far from meeting the business needs of future home networks
The disadvantage of this solution is that it does not improve the limited coverage and the limited data transmission capacity in wired transmission or short-distance wireless transmission. The two schemes are the same, and no essential changes and improvements have been achieved

Embodiment 1

[0031] Embodiment 1. A home network system, such as Figure 4 As shown, it includes a home network controller 1, a home network terminal IA 21-2n, a wired home communication network 3 and a short-distance wireless communication network 4;

[0032] The home network controller 1 is connected to the home network terminals IA 21-2n through the wired home communication network 3 and the short-distance wireless communication network 4 respectively, that is, the above two transmission channels are provided between the home network controller and the IA at the same time, and each IA passes through The home network controllers exchange data with each other and with the external network;

[0033] Among them, the wired home communication network 3 can be selected from existing wired solutions such as PLC network, Ethernet local area network (LAN: Local Area Network), home telephone network or cable TV coaxial cable. Considering the coverage and universality of PLC, this example PLC is s...

Embodiment 2

[0036] Embodiment 2. A home network controller, such as Figure 5 As shown, it includes a management and control module 5, a data segmentation and reassembly module 6, and an interface module 7; these three modules can be integrated in an existing home network controller (or home gateway) including a gateway module 8, so that it has The home network controller with the features of the present invention can also be made separately as an additional component, which is placed outside the existing home network controller to upgrade it to a home network controller with the features of the present invention. In this embodiment, the integrated plan;

[0037] The gateway module 8 completes the function of the existing home network controller, interacts between the home network and the external network, sends the data stream that needs to be divided and sent to the data segmentation and reassembly module 6, and receives the reorganized data stream from the data segmentation and reassem...

Embodiment 3

[0041] Embodiment 3. A home network terminal, such as Image 6 As shown, it includes a control module 9, a data segmentation and reassembly module 10, and an interface module 11; similar to the situation in the third embodiment, these three modules can be integrated into an existing home network terminal including a service module 12, or can be independently It is made as an additional component and placed externally on the existing home network terminal. In this embodiment, an integrated solution is adopted;

[0042] The business module 12 completes the functions of the existing home network terminal, and can have different functions depending on the specific equipment, such as audio, video and video playback, data processing and storage, etc. The business module 12 sends the data stream that needs to be divided and sent to the data division and reorganization Module 10, receives the recombined received data stream from the data segmentation and reassembly module 10;

Abstract

The invention discloses a home network system and a data transmission method, whose kernel idea is that when various terminals within home are to be interconnected, both the wired home commumication network and the short-range wireless commumication network are applied, that is, both the wired transmission channel and the wireless transmission channel are provided, and when specific service data are transmitted, the carrier network in practice is selected and controlled by the home network controller. The invention also provides a corresponding home network controller and home network terminals. The invention can reasonably select and allocate the carrier network in terms of the type of terminals and / or the characteristics of services applied for and the present conditions of wired / wireless network resources etc., amend the performance limitation of single transmission path, and utilize spare network resources to maximum extent.

Description

technical field [0001] The invention relates to the technical field of home networking in smart homes, in particular to a home network system, a data transmission method, and a corresponding home network controller and home network terminal. Background technique [0002] Home networking technology can turn a home into a smart home with various convenient applications. The basic solution is to connect various information appliances (IA: Information Appliance) with high communication capabilities through the home network, which can communicate with each other and with the outside world. Each IA connected to the home network , which becomes a home network terminal. [0003] The internal networking scheme of the existing home network mainly includes the following three situations: [0004] 1. Use wired transmission technology for home network networking. The wired home communication network used mainly includes telephone lines, Category 5 lines, cable TV cables, power lines, ...
