Abstract
In some implementations, a method includes receiving a connection request from a user application. A service request is sent to a radio resource control (RRC) module. An indication of failure of or a rejection to the service request due to access class barring is received from the RRC module. A retry of the user application connection request is prevented until expiration of an access-class-barring timer of the RRC module that resulted in the access class barring.
