Radio Bearer Parameter Reset for Connection Resume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing M2M communication technologies, the inconsistency of RLC and PDCP parameters between a terminal and a base station leads to connection resume failures, resulting in increased power consumption due to the need for more signaling interactions to establish a radio bearer.
Innovation Solution
The method involves setting radio bearer parameters, including RLC and PDCP parameters, to a preset value during the process of initiating a radio connection resume, ensuring consistency between the terminal and the base station, thereby improving connection resume success rates and reducing signaling interactions.

Engineering Contradiction Analysis
1Use of energy by moving object
If the terminal suspends a radio connection and attempts to resume it, then power consumption is reduced during standby, but connection resume failure occurs due to inconsistent RLC and PDCP parameters between terminal and base station
Solution Approach 1:
The terminal performs preliminary actions by resetting RLC and PDCP parameters to preset values before initiating the connection resume process. This preliminary parameter synchronization ensures that when the connection is resumed, both terminal and base station have consistent parameter states, preventing resume failures and avoiding the need for additional signaling interactions that would increase power consumption.
2Reliability
If the terminal performs additional signaling interactions to establish a radio bearer, then connection resume success rate is improved, but power consumption increases
Solution Approach 1:
The terminal performs preliminary parameter resetting to preset values before connection resume, ensuring parameter consistency is established in advance. This eliminates the need for subsequent signaling interactions that would be required to synchronize parameters, thereby maintaining high connection resume success rates while minimizing power consumption.
3Reliability
If the terminal maintains consistent RLC and PDCP parameters with the base station, then connection resume success rate is improved, but device complexity increases due to parameter management
Solution Approach 1:
The terminal changes parameters by resetting RLC and PDCP parameters to predetermined preset values during connection suspension and resume processes. This parameter change strategy simplifies parameter management compared to maintaining complex dynamic parameter synchronization, while ensuring consistent parameter states between terminal and base station for successful connection resumption.

AI summary
Provided are a method and device for processing a radio bearer, a terminal and a base station. The method for processing a radio bearer includes: after receiving a connection suspend instruction sent by a base station, a terminal sets a radio bearer parameter to a preset value according to the connection suspend instruction; or the terminal sets the radio bearer parameter to the preset value in a process of initiating a radio connection resume. The initiating a radio connection resume by the terminal includes: the terminal sending a radio connection resume request to the base station and waiting for a connection resume response from the base station. The radio bearer parameter includes at least one of a RLC parameter and a PDCP layer parameter. The present invention solves the problem in the existing art that the base station and the terminal do not have a consistent RLC parameter and a consistent PDCP parameter on a radio bearer between the terminal and the base station resulting in a connection resume failure of the terminal, so the terminal needs more signaling interactions to establish the radio bearer which causes increased power consumption of the terminal.
