Radio access network notification area update failure
First Claim
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.

Abstract
A base station transmits to a wireless device, first message(s) indicating an RRC state transition of the wireless device from an RRC connected state to an RRC inactive state. The first message(s) comprise a parameter indicating a value associated with a wireless device RAN notification area update timer for a periodic RAN notification area update procedure. The base station receives a second message indicating a RAN notification area update in response to expiry of the wireless device RAN notification area update timer. The base station starts a network RAN notification area update timer in response to the receiving of the second message. The base station transmits to a core network entity and in response to an expiration of the network RAN notification area update timer, a third message indicating a wireless device context release request for the wireless device. The third message comprises an identifier of the wireless device.

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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
