Abstract

A system and method for authorizing access to a transmission station for a mobile device is disclosed. The mobile device can receive device extended access barring (EAB) configuration information in a broadcast control channel (BCCH) from a transmission station. The mobile device can bar the mobile device configured for EAB and having characteristics identified in the EAB configuration information for barring from accessing the transmission station. Alternatively, a system and method for barring a mobile device from accessing a transmission station is disclosed. The transmission station can receive from the mobile device a radio resource control (RRC) connection establishment request. The transmission station can configure a system information block (SIB) with extended access barring (EAB) configuration information. The transmission station can broadcast the SIB with EAB configuration information to the mobile device.

First claim

What is claimed is:

1. A user equipment (UE) configured for extended access barring (EAB), comprising:
a transceiver module configured to receive EAB configuration information in a system information block (SIB) from a node, wherein the SIB is a SIB type 14 in a long term evolution (LTE) system or the SIB is a SIB type 21 in a universal mobile telecommunications system (UMTS); and
a processing module configured to bar transmissions to the node for the UE configured for EAB when the SIB has characteristics identified in the EAB configuration information for barring.

2. The UE of claim 1 , wherein the transceiver module is further configured to receive periodically a system information block (SIB) type 1 in a long term evolution (LTE) system and a master information block (MIB) in a universal mobile telecommunications system (UMTS), and receive a dedicated SIB for EAB associated with the SIB type 1 in the LTE system or a dedicated SIB for EAB associated with the MIB in the UMTS; and the processing module is further configured to update the EAB configuration information periodically.

3. The UE of claim 1 , wherein the transceiver module is further configured to receive a system information block (SIB) type 1 in a long term evolution (LTE) system and a master information block (MIB) in a universal mobile telecommunications system (UMTS) and receive a dedicated SIB for EAB associated with the SIB type 1 in the LTE system and a dedicated SIB for EAB associated with the MIB in the UMTS prior to a request for a radio resource control (RRC) connection establishment for delay tolerant access with the node; and the processing module is further configured to update the EAB configuration information prior to the request for the RRC connection establishment.

4. The UE of claim 1 , wherein the transceiver module is further configured to receive a paging message with an EAB indication and receive a dedicated system information block (SIB) for EAB associated with the EAB indication in a long term evolution (LTE) system and a dedicated SIB for EAB associated with the EAB indication in a universal mobile telecommunications system (UMTS) prior to a request for a radio resource control (RRC) connection establishment for delay tolerant access with the node; and the processing module is further configured to update the EAB configuration information prior to the request for the RRC connection establishment.

5. The UE of claim 1 , wherein the transceiver module is further configured to receive a paging message with an EAB indication prior to a request for a radio resource control (RRC) connection establishment for delay tolerant access with the node, wherein the EAB indication includes barring category information; and the processing module is further configured to update the EAB configuration information prior to the request for the RRC connection establishment.

6. The UE of claim 1 , wherein the transceiver module is further configured to send to the node a radio resource control (RRC) connection establishment request including an EAB classification for the UE configured for EAB, wherein the EAB classification defines the UE's roaming category.

7. The UE of claim 1 , wherein the UE is configured to connect to at least one of a wireless local area network (WLAN), a wireless personal area network (WPAN), and a wireless wide area network (WWAN), and the UE includes an antenna, a touch sensitive display screen, a speaker, a microphone, a graphics processor, an application processor, internal memory, or a non-volatile memory port.

8. A node configured for extended access barring (EAB), comprising:
a transceiver module configured to receive from a user equipment (UE) a radio resource control (RRC) connection establishment request and broadcast a system information block (SIB) with extended access barring (EAB) configuration information to the UE, wherein the SIB is a SIB type 14 in a long term evolution (LTE) system or the SIB is a SIB type 21 in a universal mobile telecommunications system (UMTS); and
a processing module configured to configure the SIB with EAB configuration information.

9. The node of claim 8 , wherein the RRC connection establishment request includes an EAB classification for the UE configured for EAB, the transceiver module is further configured to send to the UE a RRC connection establishment rejection message for the UE configured for EAB and having the EAB classification defined for EAB in the EAB configuration information for the node, wherein the EAB classification defines the UE's roaming category.

10. The node of claim 8 , wherein the transceiver module is further configured to receive a priority class indicator information element (IE) or an EAB indicator IE from a core network, wherein the priority class indicator IE defines the UE's roaming category used for configuring the SIB with EAB configuration information, and the EAB indicator IE defines the UE's roaming category used for configuring the SIB with EAB configuration information.

11. The node of claim 8 , wherein the node includes a base station (BS), a Node B (NB), an evolved Node B (eNB), a base band unit (BBU), a remote radio head (RRH), a remote radio equipment (RRE), a relay station (RS), a radio equipment (RE), or other type of wireless wide area network (WWAN) access point.
