Embodiment 1

[0089] The bandwidth adjustment method in this embodiment is applicable to adjusting the channel bandwidths of the multiple network systems in the same shared frequency band when multiple network systems share the bandwidth of the same common frequency band.

[0090] In this embodiment, in order to avoid interference between multiple network systems, there is a bandwidth used to reduce mutual interference between network systems between any two network systems, which is recorded as the guard bandwidth, that is, the channel of multiple network systems And the guard bandwidth between the channels of any two network systems is within the bandwidth of the same shared frequency band.

[0091] In this embodiment, the channel of any network system may be a continuously extended channel; it may also be a channel composed of multiple channel frequency bands and having a guard interval between adjacent two-channel channels. It is also possible that the channels of one or more network sy...

Embodiment 2

[0109] This embodiment is a further optional embodiment of embodiment 1, and its differences from embodiment 1 mainly include:

[0110] In this embodiment, this embodiment is executing image 3 Step 301 adjusts the bandwidth of the channel of the first network system, the bandwidth of the channel of the second network system adjacent to the protection bandwidth, determines the bandwidth update value of the channel of the first network system, and the bandwidth of the second network system When the bandwidth update value of the channel of the network system and the bandwidth update value of the guard bandwidth, except that the bandwidth update value of the channel of the first network system and the bandwidth update value of the channel of the second network system are adjusted according to the schematic adjustment method provided in Embodiment 1, Bandwidth update value meets GB n,1l =g(BW n,1 ,BW n,2 ) conditions, the adjustment is further made to satisfy the following func...

Embodiment 3

[0140] see Figure 7 As shown, this embodiment provides a bandwidth adjustment controller 600. The bandwidth adjustment controller 600 is set in the network as a controller for controlling the bandwidth adjustment of the channel of the first network system and the channel of the second network system. It can exist as an independent body, and can also be integrated with any network device in the prior art.

[0141] The bandwidth adjustment controller 600 in this embodiment mainly includes: a bandwidth adjustment unit 601 and a network interface 602. The connection relationship and working principle of each part are as follows:

[0142] The bandwidth adjustment unit 601 is configured to adjust the bandwidth of the channel of the first network system and the bandwidth of the channel of the second network system adjacent to the protection bandwidth according to a user request or a channel state, and determine the first The bandwidth update value of the channel of the network sys...

Abstract

The present invention relates to the field of communications, discloses a bandwidth adjustment method and a bandwidth adjustment controller, the adjustment method comprising: according to the user request or channel state, determine the bandwidth update value of the channel of the first network system, and the bandwidth update value of the channel of the second network system, and the bandwidth update value of the protection bandwidth, so that the bandwidth of the first network system after the update, and the bandwidth of the channel of the second network system meets the requirements of the user request or adapt to the channel state. The application of this technical solution can be applied to multiple network systems to share a bandwidth resource, the channel between multiple network systems is adjusted, which is conducive to improving the application efficiency of bandwidth resources and ensuring the anti-interference ability of each network system.

Description

technical field [0001] The invention relates to the communication field, in particular to a bandwidth adjustment method and a bandwidth adjustment controller. Background technique [0002] The bandwidth is the difference between the highest frequency and the lowest frequency of the signal when transmitting an analog signal, that is, the allowable value of the frequency bandwidth required to ensure the transmission rate and quality of a certain transmission information. [0003] In wireless communication, the frequency band where the signal transmission of the network system is recorded as the channel of the network system, and the frequency range owned by the channel is called the bandwidth of the signal channel. [0004] With the development of wireless communication technology, bandwidth resources are becoming more and more scarce. In order to make full use of the limited bandwidth for wireless network communication, multiple users of the network system share the same band...
