Method and apparatus for controlling network access in a wireless communication system

摘要

A method and apparatus are provided for controlling network access in a wireless communication system. An infrastructure device, which may reside in, or be communicatively coupled to, any of an access network, a core network, and a service network, implements a device class prioritization control function (DCP-CF) that receives a geographical location of an incident, determines one or more of a cell and an access node corresponding to the geographical location, determines one or more access class barring parameters for the cell and/or access node, determines whether to enable access class barring at the cell and/or access node and, in response to determining to enable access class barring at the cell and/or access node, provides the one or more access class barring parameters to the cell and/or access node.

主权项

1. A method for controlling network access in a wireless communication system, the method comprising:
receiving, at an infrastructure device, a geographical location of an incident; determining, by the infrastructure device, one or more of a cell and a corresponding access node corresponding to the geographical location; determining one or more access class barring parameters comprising acBarringFactor, acBarringTime, acBarringForEmergency, and/or acBarringForSpecialAC for the one or more of the cell and the corresponding access node; determining whether to enable access class barring at one or more of the cell and the corresponding access node based on the access class barring parameters; and in response to determining to enable access class barring at one or more of the cell and the corresponding access node, providing the one or more one or more access class barring parameters to the one or more of the cell and the corresponding access node; wherein determining whether to enable access class barring comprises: receiving, by the infrastructure device, one or more of an incident type, an incident severity, an operational status of the one or more of the cell and the access node, and an administrative status of the one or more of the cell and the access node; and determining whether to enable access class barring based on one or more of the incident type, the incident severity, the operational status of the one or more of the cell and the access node, and the administrative status of the one or more of the cell and the access node wherein access is barred when a combination of the incident type, the incident severity, and a loading for a cell exceeds a trigger.
