Dynamic scheduling method for carrier frequency certificates

Abstract

The invention discloses a dynamic scheduling method for carrier frequency certificates, comprising the steps of: acquiring a scheduling parameter alpha of a carrier frequency certificate of each cell in a polling manner; judging alpha to generate a distributing queue and a dismantling queue; sequencing the distributing queue and the dismantling queue according to alpha; matching the distributing queue and the dismantling queue according to the priority level of the queues; distributing and dismantling the carrier frequency certificates according to the primary scheduling quantity of distributed and dismantled carrier frequency certificates, and updating the cells subjected to distributing failures and dismantling failures to a black list; generating a forcible distributing queue and a forcible dismantling queue; sequencing the forcible distributing queue and the forcible dismantling queue; matching the forcible distributing queue and the forcible dismantling queue according to the priority level in the queues; distributing and dismantling certificates according to the secondary scheduling quantity of distributed and dismantled carrier frequency certificates, and updating the cells subjected to distributing failures and dismantling failures to the black list; and emptying all the queues and returning alpha to zero.

Description

Technical field: [0001] The invention relates to the field of mobile communication, in particular to a method for dynamically dispatching a carrier frequency license in the field of mobile communication. Background technique [0002] In the context of mobile communication networks, there is an imbalance between the supply and demand of carrier frequency license resources, and the demand is greater than the available supply. There are two reasons for this phenomenon: [0003] First: The number of physical carrier frequencies in the network is far greater than the number of licenses configured in the network. There are many reasons for this phenomenon, such as: the expansion of network spare parts, the deployment of carrier frequencies in various service areas, and the current widely used Double-density carrier frequency (one physical carrier frequency in double-density carrier frequency can be configured with two logical carrier frequencies, but the actual purchase may only p...

Problems solved by technology

[0004] Second: The idle and busy hours of each area are inconsistent, and the network planning allocates carrier frequency licenses according to the busy hours of each area, which causes a waste of carrier frequency license resources in idle hours

[0005] With the increase in the number of base stations and the growth of traffic in individual areas, the imbalance between the supply and demand of carrier frequency license resources is becoming more and more serious. Operators need to invest a lot of money to solve this imbalance. The decline in resource utilization has resulted in an increase in operating costs

[0006] The existing carrier frequency license resource is configured with a certain number of license resources for a BSC (base station controller) or an area. The configuration depends on the specific conditions of the network, but the configuration of the existing carrier frequency license resource is a static configuration. Dynamic scheduling cannot be implemented, and once the actual number of carrier frequencies in the network exceeds the number of licenses, carrier frequency data cannot be configured and capacity expansion cannot be performed

[0007] Aiming at the defects that the capacity of the network in the prior art is limited by the number of carrier frequency licenses, the carrier frequency licenses are statically configured, the configuration cannot be dynamically allocated during idle and busy times, and the maximum utilization of carrier frequency license resources cannot be realized, a kind of An Improved Resource Scheduling Method for Carrier License
