Problems solved by technology
The current TV network adopts the broadcast mode, and users can only receive TV programs through the access devices such as the amplifier 360 and the splitter 370, and cannot perform two-way communication, and cannot carry out voice services and data services.
[0006] To sum up, the current types of telecommunications services are networked separately, and services are connected to dedicated terminals through dedicated access devices, resulting in waste of line resources. In some areas, repeated networking is carried out, and users carry out various In service, different access devices are required for different services, which increases user costs

The present invention provides a telecommunications service integrated access system, which comprises a communication module and a signal conversion module. The communication module is used for receiving and transmitting a radio-frequency signal loaded with audio service, broadcast television service and data service. The communication module comprises a downlink receiving unit, an identifying unit, a downlink transmission unit, an uplink receiving unit and an uplink transmission unit. The signal conversion module is used for transmitting the radio-frequency signal received by the communication module to a service terminal respectively and is also used for transmitting a baseband signal sent by the service terminal to the communication module. The signal conversion module comprises a downlink signal receiving unit, a downlink signal conversion unit, a downlink signal transmission unit, an uplink signal receiving unit, an uplink signal conversion unit and an uplink signal transmission unit. The telecommunications service integrated access system of the invention supports ''triple play'' wireless access system, capable of realizing HDTV, analog television, computer internet, digital broadcast and IP telephone communication, avoiding the duplicated networking and saving circuit resources.
Description
technical field [0001] The present invention relates to the field of network communication, and more specifically relates to a wireless access system that utilizes wireless broadband network technology to realize the three-network integration of a telecommunication network, a broadcast television network and a computer communication network. Background technique [0002] With the development of communication technology, telephone technology, data network technology and cable TV technology have developed quite maturely as single service technologies. [0003] For telephony technology mainly used for voice services, its network topology is as follows: figure 1 As shown, the user's telephone terminal 160 is connected to the distribution box 120 through a cable, and the distribution box 120 is connected to the telecommunications core network 110 through a cable. For ordinary telephone users, they can only receive voice signals through the telephone set and carry out voice servic...
