Embodiment 1
[0068] figure 2 is a flow chart showing the method executed by the user equipment according to Embodiment 1 of the present invention.
[0069] Such as figure 2 As shown, in the first embodiment of the present invention, the steps performed by the user equipment UE include: step S201, step S203 and step S205.
[0070] In step S201, when a transmitting PDCP entity (transmitting PDCP entity) submits a PDCP PDU to the lower layer (lower layer), that is, when it is delivered to the RLC layer, if the transmitting PDCP entity is associated with two RLC entities, and the two The RLC entities belong to different cell groups, for example, one belongs to the MCG and the other belongs to the SCG. At this time, it is judged whether the transmission of the primary RLC entity is suspended or not.
[0071] If the transmission of the primary RLC entity is not suspended or not suspended (or simply the primary RLC entity is suspended), then in step S203, the sending PDCP entity submits the P...
Embodiment 2
[0089] image 3 It is a flow chart showing the method executed by the user equipment according to the second embodiment of the present invention.
[0090] Such as image 3 As shown, in the second embodiment of the present invention, the steps performed by the user equipment UE include: step S301, step S303 and step S305.
[0091] In step S301, before transmitting the MCG failure information message, the UE determines whether the primary path is configured as an MCG, or determines whether the primary path is associated with the MCG.
[0092] If the UE determines that the primary path is configured as an MCG, or determines that the primary path is associated with the MCG, then in step S303, the UE performs a change operation as follows: configure the primary path as an SCG, or configure the primary path as associated with an SCG couplet.
[0093] Then, in step S305, the MCG failure information message is delivered to the lower layer for transmission.
[0094] Since the confi...
Embodiment 3
[0100] Figure 4 is a flow chart showing the method executed by the user equipment according to the third embodiment of the present invention.
[0101] Such as Figure 4 As shown, in Embodiment 3 of the present invention, the steps performed by the user equipment UE include: step S401 and step S403.
[0102] After the UE detects MCG failure, or when the UE is performing operations related to MCG failure recovery, the UE may receive an RRC reconfiguration message (RRCReconfiguration). At this point, in step S401, it is determined whether the RRC reconfiguration message is received before the UE generates / sends the MCG failure information message, or after the UE sends the MCG failure information message.
[0103] Then, in step S403, the UE performs a given operation according to whether synchronization information is included in the RRC reconfiguration message and the content of the synchronization information, and sets an RRC connection reconfiguration complete message.
