Abstract

The expansion of a category-based access control mechanism so that same may cover the conventional access control mechanism is being discussed in new radio access technology (NR). Accordingly, the present invention proposes that the category-based access control mechanism be performed for signaling as well. Specifically, a user equipment (UE): receives a configuration associated with a signaling category from a network; determines a category corresponding to a specific signaling on the basis of the configuration associated with a signaling category; and determines whether access to a cell of the category corresponding to a specific signaling is blocked.

Claims

1. A method for performing category-based access control by a wireless device configured to operate in a wireless communication system, the method comprising:

receiving barring information mapped to multiple signaling categories from a network,

wherein each of the multiple signaling categories corresponds to one or more procedures, and

wherein the one or more procedures includes one or more non-access stratum (NAS) procedures and one or more radio resource control (RRC) procedures;

initiating an update procedure related to a radio access network (RAN) based area, among the one or more procedures;

selecting, by a RRC layer of the wireless device, a signaling category, among the multiple signaling categories, corresponding to the initiation of the update procedure related to the RAN based area;

performing the category-based access control for the selected signaling category based on the barring information; and

transmitting, to the network, a RRC message for the update procedure related to the RAN based area upon that the update procedure related to the RAN based area is not barred as a result of the category-based access control for the selected signaling category.

2. The method of claim 1, wherein the update procedure related to the RAN based area includes an RRC connection resume procedure.

3. The method of claim 1, wherein the signaling category corresponding to the initiation of the update procedure related to the RAN based area is different from a signaling category corresponding to other procedures among the one or more procedures.

4. The method of claim 1, wherein the barring information includes at least one of a barring factor, a barring time, or a bitmap.

5. The method of claim 1, wherein the barring information is broadcast through system information or transmitted through an RRC message on a dedicated control channel (DCCH).

6. The method of claim 1, wherein the network is one of an eNB, a gNB, a server, a mobility management entity (MME), an access and mobility management function (AMF), or a session management function (SMF).

7. The method of claim 1, wherein the wireless device is in communication with at least one of a user equipment, a network, and/or autonomous vehicles other than the wireless device.

8. A wireless device configured to operate in a wireless communication system, the wireless device comprising:

at least one transceiver;

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising;

receiving, via the transceiver, barring information mapped to multiple signaling categories from a network,

wherein each of the multiple signaling categories corresponds to one or more procedures, and

wherein the one or more procedures includes one or more non-access stratum (NAS) procedures and one or more radio resource control (RRC) procedures;

initiating an update procedure related to a radio access network (RAN) based area, among the one or more procedures;

selecting, by a RRC layer of the wireless device, a signaling category, among the multiple signaling categories, corresponding to the initiation of the update procedure related to the RAN based area;

performing a category-based access control for the selected signaling category based on the barring information; and

transmitting, to the network via the transceiver, a RRC message for the update procedure related to the RAN based area upon that the update procedure related to the RAN based area is not barred as a result of the category-based access control for the selected signaling category.

9. The wireless device of claim 8, wherein the update procedure related to the RAN based area includes an RRC connection resume procedure.

10. The wireless device of claim 8, wherein the signaling category corresponding to the initiation of the update procedure related to the RAN based area is different from a signaling category corresponding to other procedures among the one or more procedures.

11. The wireless device of claim 8, wherein the barring information includes at least one of a barring factor, a barring time, or a bitmap.

12. The wireless device of claim 8, wherein the barring information is broadcast through system information or transmitted through an RRC message on a dedicated control channel (DCCH).

13. The wireless device of claim 8, wherein the network is one of an eNB, a gNB, a server, a mobility management entity (MME), an access and mobility management function (AMF), or a session management function (SMF).

14. A wireless device configured to operate in a wireless communication system, the wireless device comprising:

at least one memory; and

at least one processor, operably coupled to the at least one memory,

wherein the at least one processor is configured to;

obtain barring information mapped to multiple signaling categories,

wherein each of the multiple signaling categories corresponds to one or more procedures, and

wherein the one or more procedures includes one or more non-access stratum (NAS) procedures and one or more radio resource control (RRC) procedures;

initiate an update procedure related to a radio access network (RAN) based area;

select, by a RRC layer of the wireless device, a signaling category, among the multiple signaling categories, corresponding to the initiation of the update procedure related to the RAN based area, among the one or more procedures;

perform the category-based access control for the selected signaling category based on the barring information; and

generate a RRC message for the update procedure related to the RAN based area upon that the update procedure related to the RAN based area is not barred as a result of the category-based access control for the selected signaling category.
