Methods and apparatus for radio resource control
View Patent ↗Improved systems and techniques for controlling access to network resources. A base station broadcasts extended access barring (EAB) and access class barring (ACB) information. Upon a determination by a user equipment that the user equipment requires service from the base station, the user equipment determines its EAB category and call type. The user equipment receives the EAB and ACB information broadcast by the base station and determines if it is subject to EAB based on its EAB category. If the user equipment is not subject to EAB, the user equipment determines if its call type is subject to ACB and, if the call type is subject to ACB, applies access class barring based on its call type.
1. A method comprising:
configuring at least one processor to cause an apparatus to perform the functions of:
in response to a determination that the apparatus needs to communicate with a wireless networking base station:
determining if the need for service from the base station results from a need for an emergency communication;
if the need for service from the base station does result from a need for emergency communication, causing the non-access stratum to perform emergency procedures without determining the access class barring category;
if the need for service from the base station does not result from a need for emergency communication:
determining at least one of extended access barring information or status for the apparatus or access class barring information or status for the communication, wherein the determination of the extended access barring information or status of the apparatus is carried out at the non-access stratum layer of the wireless telecommunication protocol stack being used by the apparatus;
receiving extended access barring category information broadcast by the base station;
receiving access class barring information broadcast by the base station;
determining whether the communication is subject to extended access barring; and
if it is determined that the apparatus is not subject to extended access barring, determining whether the apparatus is subject to access class barring based on the access class barring information broadcast by the base station.
