Method and apparatus for notifying access control information

Abstract

A method and an apparatus for notifying activations of extended access barring (EAB) and updates of EAB information in the field of Long Term Evolution (LTE) wireless communication systems have been proposed. In accordance with the present disclosure, the eNB notifies MTC devices of EAB changes from a paging message through the paging channel (PCH). The network could use either a single bit EAB status indicator to notify whether the EAB has been enabled or disabled or use multiple bits EAB indicator to represent different EAB parameter changes in addition to whether the EAB has been enabled or disabled. Based on the present disclosure, the network could reduce the paging overhead by require the MTC device to acquire the EAB-SIB only when it needs the EAB information.

Dependencies are inferred from the claim text.
