Machine-to-machine communication device and method for providing enhanced access barring in a wireless network

Abstract

Embodiments of a system and method for providing enhanced access barring in a Wireless Network are generally described herein. In an example, a method for controlling access in a mobile device network can include receiving access class barring (ACB) information at user equipment (UE) as part of a system information message including a first system information block, and receiving extended access barring (EAB) information at the UE as part of a system information message including a second system information block. The first system information block can be different from the second system information block.

         38 . An enhanced base station apparatus comprising:
 memory; and   processing circuitry coupled to the memory, the processing circuitry configured to:   encode a system information of a first block type including access class barring (ACB) information;   encode system information of a second block type including enhanced access barring (EAB) information, and wherein the EAB information is to reduce the overload condition using one or more categories of UEs;   process an indication of an overload condition in a mobile device network; and   encode a paging message for communication to at least a first UE, the paging message indicative of a change in EAB information for the UE.   
     
     
         39 . The enhanced base station apparatus of  claim 38 , wherein the system information of the second block type includes EAB information indicating one or more categories of UEs barred from accessing the mobile device network. 
     
     
         40 . A non-transitory computer readable medium comprising instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to communicate with a base station of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) to implement access control operations, wherein the instructions configure the UE to:
 decode access class barring (ACB) information at the UE from a first system information block (SIB);   decode enhanced access barring (EAB) information at the UE as part of a second SIB;   store the EAB information at the UE;   decode a paging message from a base station of the E-UTRAN, the message indicative of a change in EAB parameters for the UE; and   in response to the paging message:
 request updated EAB parameters from the base station; or 
 adjust access controls at the UE using the EAB information. 
   
     
     
         41 . The non-transitory computer readable medium of  claim 40 , wherein the first SIB is different from the second SIB.
