Radio link failure reporting method and user equipment
The present disclosure provides a radio link failure reporting method and user equipment. The radio link failure reporting method comprises: user equipment (UE) detecting a radio link failure (RLF) of a master cell group (MCG); the UE initiating a fast MCG link recovery procedure to recover a connection to a network side; the UE transmitting a radio link failure report to the network side, wherein the radio link failure report comprises first fast MCG link recovery information, and the first fast MCG link recovery information is used to indicate that the UE has attempted a fast MCG link recovery function based on the fast MCG link recovery procedure after a radio link corresponding to the radio link failure report fails.
1. A user equipment (UE), comprising:
a processor; and
a memory storing instructions, wherein, on the basis of the instructions, the processor is configured to:
store a radio link failure (RLF) report in a variable VarRLF-Report upon a radio link failure;
upon initiating a master cell group (MCG) failure information procedure, send an MCG failure information message to a network, and start a timer T316; and
in a case that the processor receives, from the network and while the timer T316 is running, an RRC release message, or an RRC reconfiguration message comprising a reconfiguration with sync information element, upon receiving the RRC release message or the RRC reconfiguration message, clear the RLF report stored in the variable VarRLF-Report.
2. A method performed by a user equipment (UE), comprising:
storing a radio link failure (RLF) report in a variable VarRLF-Report upon a radio link failure;
upon initiating a master cell group (MCG) failure information procedure, sending an MCG failure information message to a network, and starting a timer T316; and
upon receiving, from the network and while the timer T316 is running, an RRC release message, or an RRC reconfiguration message comprising a reconfiguration with sync information element, clearing the RLF report stored in the variable VarRLF-Report.
3. The UE according to claim 1 , wherein
the processor is further configured to, in a case that the timer T316 expires:
trigger an RRC connection reestablishment procedure; and
transmit the RLF report to the network,
wherein the transmitted RLF report includes information used to indicate that the timer T316 expires and the MCG failure information procedure is unsuccessful.
