Abstract

In a wireless communication control method in which a management server manages line selection of an unlicensed band / licensed band of UE and manages parameters of the unlicensed band, the management server has a control step for excluding UE using the licensed band from an optimization target in an unlicensed-band system, and optimizing parameters of the unlicensed band in consideration of existence of a STA and UE using the unlicensed band. Furthermore, the management server adopts, for the line selection of the UE, a pattern with which a total of communication capacity of the unlicensed bandafter the optimization of its parameters and communication capacity of the licensed band becomes high, and sets the parameters of the unlicensed band after the optimization of the line selection foran AP, the STA, and the UE of the unlicensed band.

Description

technical field [0001] The present invention relates to a wireless communication control method, a wireless communication system, and a management server. In the wireless communication control method, the management server on the network side controls the line used by a terminal device (UE), wherein the terminal device (UE) has Using CSMA (Carrier Sense Multiple Access, Carrier Sense Multiple Access) communication interface for both unlicensed wireless access and licensed wireless access, and the management server optimizes the setting parameters of unlicensed wireless access . Background technique [0002] In the wireless LAN (Local Area Network, local area network) system of the IEEE802.11 standard specification (Non-Patent Document 1), the unlicensed band wireless access using the CSMA method is adopted, and the throughput increases year by year. One and popularized. Furthermore, even in a cellular communication system using licensed frequency bands, terminal devices (U...
