Radio access network notification area update failure

1. A method comprising:

transmitting, by a first base station to a wireless device, at least one first message indicating a radio resource control (RRC) state transition of the wireless device from an RRC connected state to an RRC inactive state, wherein the at least one first message comprises a parameter indicating a value associated with a wireless device radio access network (RAN) notification area update timer for a periodic RAN notification area (RNA) update procedure;

receiving, by the first base station, a second message indicating an RNA update by the wireless device in response to expiry of the wireless device RNA update timer;

starting, by the first base station, a network RNA notification area update timer, wherein the base station determines that the periodic RNA update procedure is unsuccessful based on expiry of the network RNA update timer; and

transmitting, by the first base station to a core network entity and in response to an expiration of the network RNA update timer, a third message indicating a wireless device context release request for the wireless device, wherein the third message comprises an identifier of the wireless device.

2. The method of claim 1 , wherein the at least one first message further comprises a RNA information associated with the wireless device, the RNA information comprising at least one of:

a RAN area identifier; or

a cell identifier.

3. The method of claim 1 , further comprising releasing, by the first base station, a wireless device context of the wireless device based on the expiration of the network RNA update timer.

4. The method of claim 1 , wherein the third message further indicates that the wireless device fails in a period RNA update.

5. The method of claim 1 , wherein the core network entity determines the wireless device as being in an idle state in response to receiving the third message.

6. The method of claim 1 , wherein the first base station keeps a wireless device context of the wireless device at least during a time in which the wireless device is in the RRC inactive state, the wireless device context comprising at least one of:

a bearer configuration information;

a logical channel configuration information;

a packet data convergence protocol configuration information; or

a security information.

7. The method of claim 1 , wherein the wireless device RNA update timer is configured based on at least one of:

a moving speed of the wireless device;

a wireless device type of the wireless device;

a network slice of the wireless device; or

a bearer of the wireless device.

8. The method of claim 1 , further comprising:

transmitting, by the core network entity to a second base station, a paging message for the wireless device based on the third message; and

receiving, by the core network entity from the second base station, a response message to the paging message.

9. The method of claim 1 , wherein the wireless device transitions a RRC state from the RRC inactive state to a RRC idle state in response to failing in a period RNA update.

10. The method of claim 1 , wherein the second message comprises an RRC connection resume request message.

11. A base station comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the base station to:

transmit, to a wireless device, at least one first message indicating a radio resource control (RRC) state transition of the wireless device from an RRC connected state to an RRC inactive state, wherein the at least one first message comprises a parameter indicating a value associated with a wireless device radio access network (RAN) notification area update timer for a periodic RAN notification area (RNA) update procedure;

receive a second message indicating a RNA update by the wireless device in response to expiry of the wireless device RNA update timer;

start a network RNA update timer, wherein the base station determines that the periodic RAN update procedure is unsuccessful based on expiry of the network RNA update timer; and

transmit, to a core network entity and in response to an expiration of the network RNA update timer, a third message indicating a wireless device context release request for the wireless device, wherein the third message comprises an identifier of the wireless device.

12. The base station of claim 11 , wherein the at least one first message further comprises a RNA information associated with the wireless device, the RNA information comprising at least one of:

a RAN area identifier; or

a cell identifier.

13. The base station of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the base station to release a wireless device context of the wireless device based on the expiration of the network RNA update timer.

14. The base station of claim 11 , wherein the third message further indicates that the wireless device fails in a period RNA update.

15. The base station of claim 11 , wherein the core network entity determines the wireless device as being in an idle state in response to receiving the third message.

16. The base station of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the base station to keep a wireless device context of the wireless device at least during a time in which the wireless device is in the RRC inactive state, the wireless device context comprising at least one of:

a bearer configuration information;

a logical channel configuration information;

a packet data convergence protocol configuration information; or

a security information.

17. The base station of claim 11 , wherein the wireless device RNA update timer is configured based on at least one of:

a moving speed of the wireless device;

a wireless device type of the wireless device;

a network slice of the wireless device; or

a bearer of the wireless device.

18. The base station of claim 11 , wherein the core network entity further:

transmit, to a second base station, a paging message for the wireless device based on the third message; and

receive, from the second base station, a response message to the paging message.

19. The base station of claim 11 , wherein the wireless device transitions a RRC state from the RRC inactive state to a RRC idle state in response to failing in a period RNA update.

20. The base station of claim 11 , wherein the second message comprises an RRC connection resume request message.
