[0034] Phase 1: Shared Spectrum Pool Initialization Phase

[0035] The establishment method of the shared spectrum pool mentioned in the present invention can adopt various methods, and it can be communication and negotiation between spectrum controllers (spectrum controllers) in charge of spectrum resource allocation in different operator networks, so as to establish a shared spectrum pool. It may also be that the cluster head (cluster header) of each cell cluster collects relevant spectrum resource information of member base stations of the cell cluster, and then establishes a shared spectrum pool through a communication negotiation mechanism among cluster heads. Reference may be made to the method for establishing a shared spectrum pool disclosed in "A Method for Network Spectrum Sharing" (patent application number: 201410032758.3) filed by the applicant on January 23, 2014, and will not be repeated here.

[0105] For ease of understanding, only the differences between the second embodiment and the first embodiment are introduced here.

[0106] In the first embodiment, at the initialization stage of the shared spectrum pool, the first network and the second network divide the spectrum resources of the shared spectrum pool according to the proportion of CSG base stations in each cell cluster and the number of member base stations. The proportion of CSG base stations is used to consider that the number of users served by CSG base stations is relatively small. During the initialization process, a spectrum resource amount lower than the average value can be allocated to it, and the remaining spectrum resources in the shared spectrum pool are allocated to the OPEN. Mode of the base station, to ensure its quality of service. However, if calculated with the proportion of OPEN base stations, it has the same performance.

[0114] In the third embodiment, the first network and the second network divide the spectrum resources of the shared spectrum pool according to the number of CSG base stations and the number of member base stations, and the corresponding spectrum resource Band of cell cluster A in the shared spectrum pool A should be adjusted to:

Abstract

The invention discloses an inter-network shared frequency spectrum optimization system and method. In the optimization method, frequency spectrum resources allocated to a first network in a shared frequency spectrum pool comprise frequency spectrum resources occupied by OPEN mode base stations of a first cell cluster, the frequency spectrum resources allocated to a second network in the shared frequency spectrum pool comprise frequency spectrum resources occupied by the OPEN mode base stations of a second cell cluster, and the frequency spectrum resources occupied by each OPEN mode base station in the first cell cluster have the same magnitudes as the frequency spectrum resources occupied by each OPEN mode base station in the second cell cluster. The different demands of working modes or business loads and other changes of the base stations on the frequency spectrum are comprehensively considered, initial allocation and reallocation of the shared frequency spectrum can be realized more rationally in combination with the dynamic changes of the working modes of the base stations, and thus the spectral efficiency and the quality of service of the base stations are improved.

Description

technical field [0001] The present invention relates to an inter-network spectrum optimization system, in particular to an inter-network shared spectrum optimization system and method for dynamically allocating shared spectrum based on CSG (Closed Subscriber Group, Closed Subscriber Group) base station ratio, belonging to the technical field of wireless communication. Background technique [0002] In recent years, with the continuous development of wireless communication systems and the popularization of smart terminals, users have higher and higher requirements for data communication services, and correspondingly, the demand for transmission spectrum is also increasing. However, spectrum resources suitable for wireless transmission are limited. In order to avoid mutual interference, countries around the world are currently adopting static spectrum allocation policies, allocating some licensed frequency bands to a fixed wireless service, and the remaining unlicensed frequenc...
