Patent attributes
The disclosure provides a terminal access method and a terminal access device. The method comprises: determining, according to a value within an Enhanced Access Barring (EAB) parameter corresponding to an Access Class (AC) configured by a system, whether to allow access of a terminal corresponding to the AC; when the corresponding AC is determined to be not barred according to the EAB parameter, then according to a common Access Class Barring (ACB) parameter broadcasted by the existing system, performing access allowed judgment; when the corresponding AC is determined to be barred according to the EAB parameter, then, according to a barring time parameter configured by the system, calculating a barring time for re-accessing the system. In the method of the disclosure, the EAB and the existing ACB mechanism are jointly processed, solving the problem of possible impact on a system caused when large numbers of delay-insensitive or low-priority services or terminals access a network simultaneously. Also, during the occurrence of an unexpected event, as the EAB applicable terminal is provided with appropriate control, this type of terminal is prevented from accessing the system directly without constraints, and the duration of system congestion during the unexpected event is shortened.
