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. At least one non-transitory machine readable storage medium comprising instructions to authorize access to a node for a user equipment (UE), the instructions when executed by at least one processor performs the following:
processing, at the UE, extended access barring (EAB) configuration information in a system information block (SIB) received in a broadcast control channel (BCCH) 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
barring the UE from accessing the node by the UE configured for EAB when the SIB has characteristics identified in the EAB configuration information.

2. The at least one non-transitory machine readable storage medium of claim 1 , wherein the EAB configuration information includes an EAB category, an EAB factor, or an EAB time.

3. The at least one non-transitory machine readable storage medium of claim 2 , wherein the barring category represents categories of UEs, where a first category represents UEs configured for EAB, a second category represents UEs configured for EAB not in UE's home public land mobile network (HPLMN) or a public land mobile network (PLMN) equivalent to the UE's HPLMN, and a third category represents UEs configured for EAB not in a preferred PLMN, UE's HPLMN, or the PLMN equivalent to UE's HPLMN.

4. The at least one non-transitory machine readable storage medium of claim 1 , wherein the SIB is modifiable within a modification period.

5. The at least one non-transitory machine readable storage medium of claim 1 , wherein the SIB includes a dedicated SIB for EAB or an existing SIB, and the node includes a Node B (NB) for the UMTS or an evolved Node B (eNB) for the LTE system.

6. The at least one non-transitory machine readable storage medium of claim 1 , further comprising instructions when executed by the at least one processor performs the following:
updating the EAB configuration information at the UE periodically,
wherein processing EAB configuration information further comprises:
processing a system information block (SIB) that is periodically received, the SIB having scheduling information for a SIB with EAB configuration information, and
processing the SIB with EAB configuration information.

7. The at least one non-transitory machine readable storage medium of claim 6 , wherein the SIB having scheduling information is provided by a SIB type 1 in a long term evolution (LTE) system and a master information block (MIB) in a universal mobile telecommunications system (UMTS), and the SIB with EAB configuration information includes a dedicated SIB for EAB or an existing SIB.

8. The at least one non-transitory machine readable storage medium of claim 1 , further comprising instructions when executed by the at least one processor performs the following:
requesting at the UE a radio resource control (RRC) connection establishment for delay tolerant access from the node; and
updating the EAB configuration information at the UE prior to requesting RRC connection establishment for delay tolerant access,
wherein processing EAB configuration information further comprises:
processing a system information block (SIB) having scheduling information for a SIB with EAB configuration information, and
processing the SIB with EAB configuration information.

9. The at least one non-transitory machine readable storage medium of claim 8 , wherein the SIB having scheduling information is provided by a SIB type 1 in a long term evolution (LTE) system and a master information block (MIB) in a universal mobile telecommunications system (UMTS), and the SIB with EAB configuration information includes a dedicated SIB for EAB or an existing SIB.

10. The at least one non-transitory machine readable storage medium of claim 1 , wherein processing EAB configuration information further comprises processing a paging message with an indication that EAB configuration information is modified in the SIB with EAB configuration information.

11. The at least one non-transitory machine readable storage medium of claim 1 , further comprising instructions when executed by the at least one processor performs the following:
requesting at the UE a radio resource control (RRC) connection establishment for delay tolerant access from the node;
updating the EAB configuration information at the UE prior to requesting RRC connection establishment for delay tolerant access,
wherein processing EAB configuration information further comprises processing a paging message with an EAB indication.

12. The at least one non-transitory machine readable storage medium of claim 11 , wherein the EAB indication indicates a SIB with EAB configuration information, and processing EAB configuration information further comprises processing the SIB with EAB configuration information.

13. The at least one non-transitory machine readable storage medium of claim 11 , wherein the SIB with EAB configuration information includes a dedicated SIB for EAB or an existing SIB.

14. The at least one non-transitory machine readable storage medium of claim 11 , wherein the EAB indication includes barring category information.

15. The at least one non-transitory machine readable storage medium of claim 1 , further comprising instructions when executed by the at least one processor performs the following:
processing, by the UE, a radio resource control (RRC) connection establishment request for transmission to the node, the RRC connection establishment request including an EAB classification for the UE configured for EAB.

16. The at least one non-transitory machine readable storage medium of claim 15 , wherein the EAB classification for the UE configured for EAB is included in an EAB configuration information element (IE).

17. The at least one non-transitory machine readable storage medium of claim 15 , wherein the EAB classification defines the UE's roaming category.

18. At least one non-transitory computer readable storage medium comprising instructions for barring a UE from accessing a node, the instructions when executed by at least one processor performs the following:
processing, at the node, a radio resource control (RRC) connection establishment request received from the UE;
configuring a system information block (SIB) with extended access barring (EAB) configuration information, 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
providing the SIB with EAB configuration information for broadcast to the UE.

19. The at least one non-transitory machine readable storage medium of claim 18 , further comprising instructions when executed by the at least one processor performs the following: processing at the node an overload start message received from a core network prior to configuring the SIB with EAB configuration information.

20. The at least one non-transitory machine readable storage medium of claim 18 , further comprising instructions when executed by the at least one processor performs the following:
processing, at the node, an overload stop message received from a core network;
disabling the SIB with EAB configuration information or removing the EAB configuration information from the SIB with EAB configuration information; and
providing SIBs without EAB configuration information for broadcast to the UE.

21. The at least one non-transitory machine readable stor
