Problems solved by technology

[0003] At present, the uplink and downlink of the traditional network structure use the same frequency band. The mobile network mainly communicates through the base station. The cellular network has a high degree of commercialization and many wireless services. The demand for the downlink is very large, which can easily lead to low bandwidth transmission speed and slow network speed
Although in some cases, some network requirements can be evacuated through WiFi (wireless network) to increase the sense of experience, but the power of WiFi is small and the coverage is only 100 meters, which cannot meet the needs of fast-moving carriers for the network.

Embodiment 1

[0020] refer to figure 1 , is a schematic diagram of the asymmetric communication network in Embodiment 1 of the present invention. The asymmetric communication network in the embodiment of the present invention includes a blank TV band base station 20 and a second base station different from the blank TV band base station 20, and the blank TV band base station 20 transmits communication The data is sent to the mobile terminal 10 for downlink, and the mobile terminal 10 directly transmits the communication data to the second base station 30 for uplink, and the second base station 30 transmits the communication data to the blank TV band base station 20 through the network.

[0021] The transmission frequency of the white space TV base station 20 is between 512MHz and 698MHz, and can reach a bandwidth of 180MHz. Compared with the current more mature wireless network WiFi, its transmission distance is longer and the network transmission speed is faster, but the white space TV base...

Embodiment 2

[0026] Different from Embodiment 1, this embodiment adopts a WiMAX (Worldwide Interoperability for Microwave Access, i.e. Global Microwave Interconnection Access) base station or other wireless base stations such as WiFi base stations, 3G (Wireless Wide Area Network) base stations, etc. as the second base station 30, which This communication network structure enables the uplink and downlink of the mobile terminal 10 to use two different paths for data transmission, making data transmission more efficient.

[0027] It can be understood that, in other embodiments, downlink data transmission may also be connected to the network using a composite network structure combined with multiple base stations such as WiMAX base stations, 3G base stations, and WiFi base stations. The communication network with an asymmetric structure of the present invention overcomes the defect of low transmission speed of the existing network bandwidth, and can well meet the requirements of fast-moving car...

Abstract

The invention discloses an asymmetric communication network and method. The asymmetric communication network comprises a blank television frequency band base station and a second base station different from the blank television frequency band base station, wherein the blank television frequency band base station is used for transmitting communication data to a mobile terminal to implement downlink transmission; the mobile terminal is used for directly transmitting the communication data to the second base station to implement uplink transmission; the second base station is used for transmitting the communication data to the blank television frequency band base station by virtue of a network. According to the asymmetric communication network, the downlink chain transmission is implemented by the blank television frequency band base station; the uplink chain transmission is implanted by the second base station different from the blank television frequency band base station; a high-speed blank television frequency band base station transmission channel of an existing resource is fully used; the data transmission is implemented between the uplink chain and the downlink chain by virtue of different communication paths; the broadband transmission speed is increased.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an asymmetric communication network and a communication method. Background technique [0002] With the popularization of mobile Internet devices such as smartphones and tablet computers, the demand for mobile network carriers is increasing, such as passengers, public transportation information systems, urban vehicle management systems, and environmental monitoring systems. With the rapid increase of users, wireless network traffic will become more and more congested, and the defects of cellular network bandwidth will gradually be exposed. [0003] At present, the uplink and downlink of the traditional network structure use the same frequency band. The mobile network mainly communicates through the base station. The cellular network has a high degree of commercialization and many wireless services. The downlink demand is very large, which can easily lead to low bandwidth tran...
