Access Network Resource Allocation for Multi-Connection DRB Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connection scenarios, the use of data frame compression, Ethernet header compression, and PDCP replication functions can lead to communication failures due to incorrect parsing of data packets or congestion caused by waiting data packets.
Innovation Solution
A method where a first access network device obtains information about the terminal's supported function objects, determines a quantity of these objects that a second access network device can configure, and sends this information to the second access network device, ensuring that the configured resources do not exceed the terminal's capability restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data frame compression function, Ethernet header compression function, or PDCP replication function is used in multi-connection scenario, then radio resource utilization is improved, but communication failure probability increases due to incorrect parsing of data packets or congestion
Solution Approach 1:
The patent applies preliminary action by having the first access network device obtain terminal capability information in advance and determine the quantity of first function objects that the second access network device can configure. This pre-determination ensures that the terminal's processing capacity is not exceeded, preventing incorrect parsing and congestion before they occur.
Solution Approach 2:
The patent implements feedback by having the first access network device send second information indicating the determined quantity to the second access network device. This feedback mechanism ensures that the configured quantity of function objects does not exceed the terminal's capability, thereby preventing communication failures while maintaining efficient resource utilization.
2Adaptability or versatility
If quantity of first function objects configured for terminal is increased to improve service capability, then terminal service capability is enhanced, but terminal processing overload occurs leading to communication failure
Solution Approach 1:
The first access network device performs preliminary determination of the quantity of first function objects based on terminal capability information before configuration. This ensures that the terminal is not overloaded while still providing comprehensive services within its processing capacity.
Solution Approach 2:
The patent changes the parameter of quantity of first function objects dynamically based on terminal capability information. By adjusting this parameter according to the terminal's actual processing capacity, the system optimizes between service capability and processing overload prevention.
Data Source
AI summary
A first access network device allocates, to a second access network device based on an obtained quantity, supported by a terminal, of data radio bearers (DRBs) to which a data frame compression function is applied, a quantity of DRBs the second access network device can configure for the terminal and to which the function is applied can configure, and notifies the second access network device of an allocation result.
