Problems solved by technology

However, according to the regulations of the World Telecommunication Union, the wireless spectrum used for wireless mobile communication has not increased with the increase of wireless technologies, so the spectrum allocated to each wireless access technology is very limited
[0003] Under the objective conditions of limited spectrum resources, due to the existence of multiple wireless mobile network operators in different countries or regions, this leads to the auction of limited frequency resources originally allocated to different wireless access technologies to wireless mobile networks operated by different operators. It will be rarer on the Internet
However, with the development of mobile communication technology, the number of wireless mobile users has been increasing, which has caused a mismatch between the increasing number of load users and the serious scarcity of wireless spectrum resources.
[0004] The radio and television business is also carried out by means of wireless communication, and in the frequency band of the radio and television, due to the strong periodicity of the radio and television business, the services carried out in different regions cannot completely occupy all the radio and television frequency bands, and the occupied by different regions There are also differences in channels, which cause resources to be idle in certain regions, certain time periods, or certain time periods in certain regions

Embodiment 1

[0094] The operator can directly determine the resource usage strategy according to the acquired TVWS usage information. Such as image 3 As shown, the process for mobile network operators to share white space spectrum for broadcast TV includes:

[0095] Step 301: The central controller C1 of the operator A obtains, maintains and maintains the usage information of the broadcast television white space (TVWS).

[0096] Wherein, the TVWS usage information includes but is not limited to the following information, which can be one of the following information or a combination of them: TVWS spectrum information, area information, idle time, system information occupying TVWS, radio frequency information, coverage, etc. .

[0097] Step 302: A subordinate node or network of operator A applies for new wireless resources to the central controller C1 of the mobile network, wherein the central controller of the mobile network needs to know the capabilities of the network or node applying...

Embodiment 2

[0103] The mobile network operator cannot directly determine the resource usage strategy based on the acquired TV White Space (TVWS) usage information, and needs to negotiate with other mobile network operators. Such as image 3 As shown, the process for mobile network operators to share white space spectrum for broadcast TV includes:

[0104] Step 301: The central controller C1 of operator A acquires, maintains and maintains the usage information of TVWS.

[0105] Wherein, the TVWS usage information includes but is not limited to the following information, which can be one or a combination of the following information: TVWS spectrum information, area information, idle time, system information occupying TVWS, radio frequency information, coverage, etc.

[0106] Step 302: The subordinate nodes or networks of operator A apply for new wireless resources from the central controller, and at the same time, the central controller C1 of the network needs to know the capabilities of t...

Embodiment 3

[0124] Such as Figure 4 As shown in , it shows the processing flow for operator A's wireless resource optimization, including the following steps:

[0125] Step 401: The central controller C1 of the operator A applies to the database of the broadcasting and television operator to obtain TVWS information;

[0126] Step 402: The database of the radio and television operator receives the application and sends TVWS information to the central controller C1 of operator A, which at least includes: TVWS spectrum information, area information, idle time, etc.;

[0127] Step 403: The central controller C1 of operator A and the central controller C2 of operator B exchange TVWS usage information, which at least includes: system information, radio frequency information, coverage, etc. of TVWS occupied;

[0128] Step 404: A network or node subordinate to operator A sends a resource optimization application including TVWS to the central controller;

[0129] Step 405: The central controlle...

Abstract

The invention discloses a method and system for multiple mobile network operators to share the broadcast television white space. In the method, use information of the white space is obtained through a central controller of one mobile network operator; when subordinate networks or nodes of the mobile network operator have a new requirement for the white space or need to optimize the white space in use, a white space use strategy is determined based on the use information of the current white space of the central controller or by negotiating with the central controllers of other mobile network operators; and the central controller of the mobile network operator executes system reconfiguration or resource allocation according to the white space use strategy. Through the method and system disclosed by the invention, multiple mobile network operators can share the TVWS (Television Broadcast White Space) effectively in the same broadcast television white space resource pool, and can coexist fairly and efficiently without interference to each other.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and a system for sharing TV White Space (TVWS, TV White Space) by multiple mobile network operators. Background technique [0002] With the development of wireless mobile communication technology, mobile communication technology is constantly updated and developed. In the current mobile communication network, there are network technologies of different standards. For the same standard, there are second-generation and third-generation mobile communication technologies. At the same time, the next-generation network technology is about to be commercialized. However, according to the regulations of the World Telecommunication Union, the wireless spectrum used for wireless mobile communication does not increase with the increase of wireless technologies, so the spectrum allocated to each wireless access technology is very limited. [0003] Under the ob...
