  • Patent number: 10034197
    Abstract: A method and apparatus may be configured to receive at least one set of barring parameters from a network entity. Each set corresponds to a barring check and has a unique implicit or explicit priority. Each set of received barring parameters also corresponds to at least one application that is allowed to bypass the barring check associated with the corresponding and lower priority sets of barring parameters. An application belonging to one of the application groups corresponding to a set of barring parameters needs to pass all the barring checks according to the higher priority barring parameters to access the network. The method can also include determining whether an application bypasses the barring check associated with the corresponding and lower priority sets of barring parameters.
