I do not understand why radius-server does not require an access-request. in this way the nas sends only accounting-request and so can't be verified attributes radchek (I care that it control Simultaneous-Use) (all this only happens with some Android devices, Simultaneous-Use work with pcs)

That's not how radius works. The NAS - wireless point, switch, VPN server, whatever - is responsible for enforcing authentication and sending access-request to your radius server. I would mention CoA here, but it's clear you have a limited understanding of RADIUS and I don't want to confuse you. The important point is: This is all up to the NAS.
