Problems solved by technology

Spectrum resources, as a scarce resource, are very limited. If they are occupied, they cannot be redistributed, and once they are allocated, they will be gone. Therefore, there is a challenge of shortage of spectrum resources. On the other hand, although some spectrum resources have been allocated, , due to technical or business constraints, the owners of these allocated spectrum resources cannot effectively use the spectrum
Surveys show that at a given moment, the spec

Embodiment 1

[0064] The application scenario of this embodiment is: based on the wireless environment map information provided by the upper wireless management layer, the terminal periodically monitors the performance of the spectrum segment within its own acceptable range.

[0065] In this embodiment, the terminal implements a method for optimizing the use of spectrum resources, such as figure 2 shown, including the following steps:

[0066] Step 200: After receiving the user's specific service request, the terminal periodically sends a request to the upper wireless management layer to obtain environmental awareness information;

[0067] Here, in this embodiment, the specific service request refers to a video conference request.

[0068] The environment awareness information includes: wireless environment map information, spectrum environment information, and the signal-to-noise ratio of the spectrum segment within the acceptable range of the terminal, etc.; wherein the spectrum environ...

Embodiment 2

[0074] The application scenario of this embodiment is: the licensed spectrum of the terminal is occupied and has been switched to the unlicensed spectrum. The procedure for the terminal to perform secondary handover includes: after the terminal accesses an idle channel and starts communication, it detects the licensed terminal corresponding to the unlicensed spectrum, and continuously detects the licensed terminal corresponding to the unlicensed spectrum. When it is detected that the authorized terminal corresponding to the unlicensed spectrum needs to access, for example: when receiving an access request from the authorized terminal corresponding to the unlicensed spectrum, the terminal starts an emergency handover. Here, the emergency handover process includes: firstly, the terminal saves the current environmental parameters, and according to the scheduled priority order of the availability of all spectrums to be monitored, selects a suitable new target unlicensed spectrum, a...

Abstract

The invention discloses a method of optimizing frequency spectrum resource using. The method comprises the following steps that a terminal periodically monitors performance of a frequency spectrum segment within an acceptable range of the terminal; and when authorized frequency spectrums of the terminal are all occupied, according to the currently-monitored performance of the frequency spectrum segment within the acceptable range of the terminal, the terminal can confirm a switched target non-authorized frequency spectrum from non-authorized frequency spectrums of the frequency spectrum segment within the acceptable range of the terminal and is switched to the confirmed target non-authorized frequency spectrum. The invention simultaneously discloses the terminal of optimizing frequency spectrum resource using. The method and the terminal can effectively improve the using rate of frequency spectrum resources.

Description

technical field [0001] The present invention relates to spectrum resource utilization technology in the field of wireless communication, in particular to a method and terminal for optimizing spectrum resource utilization. Background technique [0002] The development of wireless network shows the trend of high speed, broadband, heterogeneity, and ubiquitous. At the same time, wireless networks are also facing severe challenges, mainly reflected in the following: shortage and waste of spectrum resources. On the one hand, the increase in demand for wireless services, such as the surge in mobile communication users, the expansion of applications in all aspects of public safety, and the continuous increase in TV broadcasting channels, has made wireless spectrum resources an extremely important resource in today's society. Spectrum resources, as a scarce resource, are very limited. If they are occupied, they cannot be redistributed, and once they are allocated, they will be gone...
