Abstract
A user equipment, method, and apparatus for controlling user equipment receive, from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network. The RRC inactive state is a different state from an RRC connected state and an RRC idle state, and the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure. The timer is started upon receiving the RRC release massage, and the RRC resume procedure is performed when the timer expires.
Claims4
A user equipment comprising:
- a receiver configured to receive, from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network, wherein the RRC inactive state is a different state from an RRC connected state and an RRC idle state, and wherein the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure;
- and
- a controller configured to
- start the timer upon receiving the RRC release massage, and
- perform the RRC resume procedure when the timer expires.
A method performed at a user equipment, the method comprising:
- receiving, from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network, wherein the RRC inactive state is a different state from an RRC connected state and an RRC idle state, and wherein the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure,
- starting the timer upon receiving the RRC release massage, and
- performing the RRC resume procedure when the timer expires.
An apparatus for controlling a user equipment, the apparatus comprising
- a processor and a memory, the processor configured to
- receive from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network, wherein the RRC inactive state is a different state from an RRC connected state and an RRC idle state, and wherein the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure,
- start the timer upon receiving the RRC release massage, and
- perform the RRC resume procedure when the timer expires.
