Abstract

The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present application relates to the field of wireless communication technologies, and discloses a method for processing an RLC failure, an electronic device and a computer readable storage medium. The method for processing a Radio Link Control (RLC) failure includes: receiving, by a first network device, RLC failure related information of a user equipment (UE); processing the RLC failure correspondingly by interacting with a second network device, based on the received RLC failure related information. The method of the embodiments in the present application, enables the first network device to interact with the second network device directly, so as to directly determine RLC failure processing according to the received RLC failure related information and the interaction information reported by the UE, thereby simplifying RLC processing, improving processing efficiency, facilitating to resolve the RLC failure correctly and rapidly, and improving user experience.

First claim

What is claimed is:

1. A method performed by a central unit (CU) of a base station for processing a radio link control (RLC) failure, the method comprising:
receiving, from a user equipment (UE), first information on an RLC failure;
transmitting, to a distributed unit (DU) of the base station, a UE context modification request message including the first information indicating a logical channel identifier (LCID) associated with an RLC entity needing re-establishment; and
receiving, from the DU, a UE context modification response message including second information indicating a list of secondary cells related to the RLC entity indicated in the first information.

2. A method performed by a distributed unit (DU) of a base station for processing a radio link control (RLC) failure, the method comprising:
receiving, from a central unit (CU) of the base station, a UE context modification request message including first information indicating a logical channel identifier (LCID) associated with an RLC entity needing re-establishment; and
transmitting, to the CU, a UE context modification response message including second information indicating a list of secondary cells related to the RLC entity indicated in the first information,
wherein the first information on the RLC failure is received by the CU from a user equipment (UE).

3. A central unit (CU) of a base station, the CU comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a user equipment (UE), first information on a radio link control (RLC) failure,
transmit, to a distributed unit (DU) of the base station, a UE context modification request message including the first information indicating a logical channel identifier (LCID) associated with an RLC entity needing re-establishment, and
receive, from the DU, a UE context modification response message including second information indicating a list of secondary cells related to the RLC entity indicated in the first information.

4. A distributed unit (DU) of a base station, the DU comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a central unit (CU) of the base station, a UE context modification request message including first information indicating a logical channel identifier (LCID) associated with an radio link control (RLC) entity needing re-establishment, and
transmit, to the CU, a UE context modification response message including second information indicating a list of secondary cells related to the RLC entity indicated in the first information,

wherein the first information on an RLC failure is received by the central unit from a user equipment (UE).
