ACCESS CONTROL METHOD AND DEVICE Russian patent published in 2017 - IPC H04W48/02 

FIELD: information technology.

SUBSTANCE: there are stages, in which: a replacement identifier is received on the upper level of the terminal protocol stack; a check of the specific, for the application, congestion control for data transmission (ACDC) is run on the upper level of the terminal protocol stack according to the service initiated by the terminal; and if the upper layer of the terminal protocol stack confirms that the service initiated by the terminal can pass the ACDC check and determines that the replacement identifier corresponding to the service application identifier undergoing the ACDC check replaces the test ban class access (ACB), an RRC setup request message for the access level of the terminal is sent, where the request message carries the ACB check failure indicator. Therefore, even if the terminal cannot pass the ACB check, the terminal can still perform the services of some specific applications.

EFFECT: providing the terminal with a connection for access for a specific application without performing the test ban class access.
