Embodiment 1

[0055] Step 1: UE performs operations related to MCG failure recovery;

[0056] This step can include:

[0057] The UE works in a dual connectivity (Dual Connectivity) working mode. In this working mode, the UE communicates with the base station through a master cell group (Master Cell Group: MCG) and a secondary cell group (Secondary CellGroup: SCG).

[0058] During communication with the base station, the UE detects whether a failure occurs in MCG transmission (referred to as MCG failure). When the UE detects a failure in MCG transmission, the UE may send a message carrying MCG failure-related information to the base station, and such an operation may be called an MCG failure recovery / report procedure (MCG failure recovery / report procedure), that is, When the UE detects a failure in MCG transmission, the UE triggers or starts an MCG failure recovery (MCG failure recovery) / report (MCG failure report) procedure. Preferably, when initiating / triggering this process, the UE st...

example 1

[0095] The UE sets the re-establishment reason in the RRC connection re-establishment request message to be the same as or related to the re-establishment reason in the message carrying MCG failure-related information sent by the UE:

[0096] Here, the failure type is "MCG radio link failure" as an example. When the failure type of the UE in the message carrying MCG failure related information is set to MCG radio link failure, then the UE can set the re-establishment in the RRC connection re-establishment request message. The content of the reason is that the MCG radio link fails, or the content of the reestablishment cause is set so as to correspond to the situation that the MCG radio link fails. It can also be understood that the UE sets the content of the re-establishment cause in the RRC connection re-establishment request message, so that the base station can know that the MCG radio link failure has occurred to the UE after receiving the re-establishment cause. Other fail...

example 2

[0098] The UE classifies the failure types. Different types of failures correspond to different reasons for reconstruction, and failure types of the same type correspond to the same reasons for reconstruction:

[0099] For example: when the failure type of the UE in the message carrying MCG failure-related information is set to reconfiguration failure, then the UE can set the content of the re-establishment reason in the RRC connection re-establishment request message to reconfiguration failure, corresponding to such a reconfiguration failure situation;

[0100] When the failure type of the UE in the message carrying MCG failure related information is set to synchronous reconfiguration failure, then the UE can set the content of the re-establishment reason in the RRC connection re-establishment request message as synchronous reconfiguration failure, which corresponds to synchronous reconfiguration failure a situation;

[0101] When the failure type of the UE in the message ca...

Abstract

The invention provides a control method of user equipment UE and the user equipment. The control method of the user equipment UE comprises the following steps: executing MCG failure recovery operationvia the UE; triggering an RRC connection reestablishment process of sending an RRC connection reestablishment request message to the base station under the condition of detecting that MCG failure recovery operation fails; setting a reconstruction reason in the RRC connection reconstruction request message according to the failure condition of the MCG failure recovery operation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a user equipment control method and the user equipment. Background technique [0002] With the rapid growth of mobile communication and the great advancement of technology, the world will move towards a fully interconnected network society, that is, anyone or anything can obtain information and share data at any time and anywhere. In order to enhance the mobile broadband service requirements and the communication requirements of massive IoT terminals, the new generation of communication technology (5G) will study the user's technical enhancements under dual connections and even multiple connections (RP-181469 New WID on DC and CA enhancements). [0003] Dual connectivity or multi-connection means that a UE working in a connected state establishes a physical path with more than one network node and realizes data transmi...
