1. A communications network system comprising:
a controller;
at least one wireless system; and
application equipment,
wherein the controller is configured to execute processes comprising:
a data information acquisition process to acquire information about data that the application equipment communicates via the at least one wireless system;
a wireless environment information acquisition process to acquire information about a wireless environment that has an impact on communications by the at least one wireless system;
a policy generation process to generate a plurality of communications policies that are delivered to the at least one wireless system;
a policy management process to manage the communications policies that are executed on the at least one wireless system; and
a network control process to carry out data communications with the at least one wireless system,
wherein the at least one wireless system is configured to execute processes comprising:
a policy agent control process to store the plurality of communications policies delivered by the controller, detect a status of communications by the at least one wireless system, and change to one of the plurality of stored communications policies based on a result of detecting the status of communications; and
a wireless system control process to control the information about data that the application equipment communicates via the at least one wireless system based on the communications policies, and
wherein the policy agent control process changes to the one of the plurality of stored communications policies, without inquiring the controller in advance, delivers the plurality of stored communications policies to the controller after the change to the one of the plurality of stored communications policies, and maintains the communications policies until a communications policy is delivered again.
