Abstract
According to an aspect, a wireless device, operating in a wireless network, handles transitions from Radio Resource Control, RRC, connected state to an RRC inactive state. The wireless device receives (1502), from the wireless network, a message indicating either that the wireless device is to enter the RRC inactive state or that the wireless device is to remain in the RRC inactive state. The wireless device, responsive to the message, uses (1504), for inactive state operation, at least one previously stored inactive state parameter corresponding to a parameter omitted from the message.
Claims19
A method, in a wireless device operating in a wireless network, for handling transitions from Radio Resource Control (RRC) connected state to an RRC inactive state, the method comprising:
- receiving, from the wireless network, a message indicating either that the wireless device is to enter the RRC inactive state or that the wireless device is to remain in the RRC inactive state;
- and
- responsive to the message, using, for inactive state operation, at least one previously stored inactive state parameter corresponding to a parameter omitted from the message, wherein the at least one previously stored inactive state parameter comprises any one or more of the following:
- a paging configuration parameter;
- a next hop chaining count for refreshing keys at subsequent resume requests;
- an early data transmission configuration parameter;
- a wait time parameter to indicate the wireless device shall not try to resume or connected to a cell until a wait timer expires;
- a cell reselection priority parameter;
- frequency redirection information;
- and
- a cell quality derivation parameter.
A method, in a wireless device operating in a wireless network, for handling transitions from Radio Resource Control (RRC) connected state to an RRC inactive state, the method comprising:
- autonomously entering the RRC inactive state;
- and
- using, for inactive state operation, at least one previously stored inactive state parameter, wherein the at least one previously stored inactive state parameter comprises any one or more of the following:
- a paging configuration parameter;
- a next hop chaining count for refreshing keys at subsequent resume requests;
- an early data transmission configuration parameter;
- a wait time parameter to indicate the wireless device shall not try to resume or connected to a cell until a wait timer expires;
- a cell reselection priority parameter;
- frequency redirection information;
- a cell quality derivation parameter.
A method, in a wireless device operating in a wireless network, for handling transitions from Radio Resource Control (RRC) connected state to an RRC inactive state, the method comprising:
- transitioning from the RRC inactive state to the RRC connected state;
- and
- storing at least one inactive state parameter for use when subsequently re-entering the RRC inactive state, wherein the at least one inactive state parameter comprises any one or more of the following:
- a paging configuration parameter;
- an early data transmission configuration parameter;
- a wait time parameter to indicate the wireless device shall not try to resume or connected to a cell until a wait timer expires;
- a cell reselection priority parameter;
- frequency redirection information;
- and
- a cell quality derivation parameter.
A method, in a wireless device operating in a wireless network, for handling transitions from Radio Resource Control (RRC) connected state to an RRC inactive state, the method comprising:
- receiving, from the wireless network, a message indicating either that the wireless device is to enter the RRC inactive state or that the wireless device is to remain in the RRC inactive state, wherein the message comprises one or more inactive state parameters corresponding to previously stored inactive state parameters in the wireless device;
- and
- responsive to the message, using, for inactive state operation, at least one previously stored inactive state parameter corresponding to a parameter omitted from the message, wherein the at least one previously stored inactive state parameter comprises any one or more of the following:
- a paging configuration parameter;
- a next hop chaining count for refreshing keys at subsequent resume requests;
- an early data transmission configuration parameter;
- a wait time parameter to indicate the wireless device shall not try to resume or connected to a cell until a wait timer expires;
- a cell reselection priority parameter;
- frequency redirection information;
- a cell quality derivation parameter;
- and
- a measurement configuration parameter to be used in the RRC inactive state;
- and
- replacing the previously stored inactive state parameters corresponding to the one or more inactive state parameters in the message with the one or more inactive state parameters in the message and using the inactive state parameters in the message for inactive state operation.
