Radio communication system, radio terminal, radio network, radio communication method and program
A wireless communication system comprises: a setting notifying means for notifying, to a radio terminal, setting information related to at least one of the radio terminal's collection of measurement information and the radio terminal's reporting of the measurement information to a radio network; a status notifying means for notifying, to the radio network, a status related to at least one of the radio terminal's collection of the measurement information and the radio terminal's reporting of the measurement information; and a re-establishing means for receiving the status and determining whether to re-establish the setting information.
1. A User Equipment (UE) configured to communicate with a radio network, the UE comprising:
a transceiver; and,
at least one processor configured to:
detect a radio link failure;
store measurement results related to the detected radio link failure;
control the transceiver to transmit, to the radio network, radio link failure status information indicating that the UE has the measurement results related to the detected radio link failure, wherein the radio link failure status information does not include the measurement results related to the detected radio link failure; and
control the transceiver to receive, from the radio network, a message indicating that a report of the measurement results related to the detected radio link failure is not required,
wherein the UE is configured to not transmit the report of the measurement results related to the detected radio link failure when the UE has received the message indicating that the report of the measurement results related to the detected radio link failure is not required.
2. The UE according to claim 1 , wherein the UE is capable of transmission of the report of the measurement results related to the detected radio link failure upon reception of a report request of the report of the measurement results related to the detected radio link failure.
3. The UE according to claim 1 , wherein the UE is capable of transmission of the report of the measurement results related to the detected radio link failure upon reception of a report request of the report of the measurement results related to the detected radio link failure after transmission of the radio link failure status information.
4. The UE according to claim 1 , wherein the UE transmits the report of the measurement results related to the detected radio link failure when the UE has received the report request of the report of the measurement results related to the detected radio link failure after transmission of the radio link failure status information.
5. A radio network configured to communicate with a User Equipment (UE), the radio network comprising:
a transceiver; and,
at least one processor configured to:
control the transceiver to receive, from the UE, radio link failure status information indicating that the UE has measurement results related to radio link failure detected by the UE, wherein the radio link failure status information does not include the measurement results related to the detected radio link failure; and
control the transceiver to transmit, to the UE, a message indicating that a report of the measurement results related to the detected radio link failure is not required.
6. The radio network according to claim 5 , wherein the radio network receives the report of the measurement results related to the detected radio link failure when the radio network has transmitted the report request of the report of the measurement results related to the detected radio link failure after reception of the radio link failure status information.
7. A method for a User Equipment (UE) configured to communicate with a radio network, the method comprising:
detecting radio link failure;
storing measurement results related to the detected radio link failure;
transmitting, to the radio network, radio link failure status information indicating that the UE has the measurement results related to the detected radio link failure, wherein the radio link failure status information does not include the measurement results related to the detected radio link failure; and
receiving, from the radio network, a message indicating that a report of the measurement results related to the detected radio link failure is not required,
wherein the UE is configured to not transmit the report of the measurement results related to the detected radio link failure when the UE has received the message indicating that the report of the measurement results related to the detected radio link failure is not required.
8. A method for a radio network configured to communicate with a User Equipment (UE), the method comprising:
receiving, from the UE, radio link failure status information indicating that the UE has measurement results related to radio link failure detected by the UE, wherein the radio link failure status information does not include the measurement results related to the detected radio link failure; and
transmitting, to the UE, a message indicating that a report of the measurement results related to the detected radio link failure is not required.
