Abstract
A wireless device in an RRC connected state receives a radio resource control (RRC) message from a base station. The wireless device transitions from the RRC connected state to an RRC inactive station in response to the RRC message. The RRC message indicates an active time period in which the wireless device is reachable by paging. The wireless device monitors to receive a paging message during the active time period after the transitioning. The wireless stops monitoring for the paging message in response to the expiration of the active time period.
Claims20
A method comprising:
- receiving, by a wireless device from a base station, a radio resource control (RRC) message to transition the wireless device from an RRC connected state to an RRC inactive state, the RRC message indicating a time period in which the wireless device is reachable by paging;
- transitioning, by the wireless device and in response to the RRC message, from the RRC connected state to the RRC inactive state while remaining in a connection management (CM) connected state;
- monitoring, in the RRC inactive state, to receive a paging message during the time period after the transitioning;
- and
- in response to an expiration of the time period, stopping the monitoring to receive the paging message.
A wireless device, comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive, from a base station, a radio resource control (RRC) message to transition the wireless device from an RRC connected state to an RRC inactive state, the RRC message indicating a time period in which the wireless device is reachable by paging;
- transition, in response to the RRC message, from the RRC connected state to the RRC inactive state while remaining in a connection management (CM) connected state;
- monitor, in the RRC inactive state, to receive a paging message during the time period after the transitioning from the RRC connected state to the RRC inactive state in response to the RRC message;
- and
- in response to an expiration of the time period, stop the monitoring to receive the paging message.
A system comprising:
- a base station comprising:
- one or more first processors;
- and
- first memory storing instructions that, when executed by the one or more first processors, cause the base station to:
- determine to release a radio resource control (RRC) connection with a wireless device;
- and
- send, to the wireless device, an RRC message to transition the wireless device from an RRC connected state to an RRC inactive state, the RRC message indicating a time period in which the wireless device is reachable by paging;
- and
- the wireless device comprising:
- one or more second processors;
- and
- second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive, from the base station, the RRC message;
- transition, in response to the RRC message, from the RRC connected state to the RRC inactive state while remaining in a connection management (CM) connected state;
- monitor, in the RRC inactive state, to receive a paging message during the time period after the transitioning from the RRC connected state to the RRC inactive state in response to the RRC message;
- and
- in response to an expiration of the time period, stop the monitoring to receive the paging message.
