and one or more processors configured to execute the instructions to: obtain information related to change request for quality requirement of a first service managed by a first management apparatus involved in control for a radio resource of a base station; and evaluate a quality change caused in a second service managed by a second management apparatus, the second service sharing the radio resource with the first service, in response to the change request for the quality requirement of the first service, to determine permission for the change request for the quality requirement of the first service. ### Claim 2 (depends on 1) The node apparatus according to claim 1, wherein the one or more processors are configured to execute the instructions to: further obtain information related to quality of the second service, and evaluate the quality change caused in the second service in response to the change request for the quality requirement of the first service, based on the information related to the quality of the second service, to determine permission for the change request for the quality requirement of the first service. ### Claim 3 (depends on 2) The node apparatus according to claim 2, wherein the information related to the quality of the second service includes information related to an estimate of the quality of the second service in case that the quality requirement of the first service is changed, and the one or more processors are configured to execute the instructions to evaluate the quality change caused in the second service in response to the change request for the quality requirement of the first service, based on the estimate of the quality of the second service, to determine permission for the change request for the quality requirement of the first service. ### Claim 4 (depends on 3) The node apparatus according to claim 3, wherein the information related to the quality of the second service further includes information related to quality requirement of the second service, and the one or more processors are configured to execute the instructions to determine permission for the change request for the quality requirement of the first service, in case that the estimate of the quality of the second service satisfies the quality requirement of the second service. ### Claim 5 (depends on 3) The node apparatus according to claim 3, wherein the one or more processors are configured to execute the instructions to estimate the estimate of the quality of the second service based on a use state of the radio resource. ### Claim 6 (depends on 5) The node apparatus according to claim 5, wherein the one or more processors are configured to execute the instructions to further perform control for the radio resource of the base station in accordance with determination of permission of the change request for the quality requirement of the first service. ### Claim 7 (depends on 3) The node apparatus according to claim 3, wherein the one or more processors are configured to execute the instructions to obtain the information related to an estimate of the quality of the second service by receiving the information from the base station. ### Claim 8 (depends on 7) The node apparatus according to claim 7, wherein the one or more processors are configured to execute the instructions to further perform the change request for the quality requirement of the first service. ### Claim 9 (depends on 1) The node apparatus according to claim 1, wherein the first management apparatus is located at an edge of a mobile communication network. ### Claim 10 (depends on 1) The node apparatus according to claim 1, wherein the second management apparatus is disposed in a cloud network connected via a mobile communication network. ### Claim 11 A method comprising: obtaining information related to change request for quality requirement of a first service managed by a first management apparatus involved in control for a radio resource of a base station; and evaluating a quality change caused in a second service managed by a second management apparatus, the second service sharing the radio resource with the first service, in response to the change request for the quality requirement of the first service, to determine permission for the change request for the quality requirement of the first service. ### Claim 12 (canceled) ### Claim 13 A non-transitory computer-readable recording medium storing a program that causes a processor to execute: obtaining information related to change request for quality requirement of a first service managed by a first management apparatus involved in control for a radio resource of a base station; and evaluating a quality change caused in a second service managed by a second management apparatus, the second service sharing the radio resource with the first service, in response to the change request for the quality requirement of the first service, to determine permission for the change request for the quality requirement of the first service.
