Protocol Architecture Matching for 5G ProSe Relay Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current relay communication scenarios in 5G ProSe support only one protocol architecture, leading to communication failures when devices with mismatched protocol architectures attempt to connect.
Innovation Solution
A method and apparatus for determining protocol architecture by exchanging architecture information between devices, allowing them to match their supported and preferred protocol architectures before establishing a communication connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only one protocol architecture is supported in current relay communication scenarios, then device complexity is reduced, but communication reliability deteriorates when devices with mismatched protocol architectures attempt to connect
Solution Approach 1:
The patent applies preliminary action by having devices exchange architecture information before establishing communication connections. The first device receives architecture information from the second device in advance, allowing the first device to determine protocol architecture compatibility before initiating the connection establishment process, thereby preventing connection failures due to mismatched protocols
Solution Approach 2:
The patent implements feedback by having the first device determine whether to establish a communication connection based on the received architecture information from the second device. This feedback mechanism allows the first device to use the architecture information to make an informed decision about connection establishment, ensuring protocol compatibility before connection is attempted
2Reliability
If protocol architecture information exchange is implemented, then communication connection reliability is improved, but message transmission complexity increases
Solution Approach 1:
The patent applies the extraction principle by isolating the protocol architecture information as a separate element within the target message. The architecture information is extracted from the overall message structure, allowing devices to process only the relevant protocol compatibility details without handling the entire complex message payload, thereby reducing processing complexity

AI summary
A method, apparatus, and device for determining protocol architecture are provided. The method includes: receiving a target message from a second device, where the target message carries first information; and determining, based on the first information and second information, whether to establish a communication connection to the second device, where the first information is used to indicate architecture information of a first protocol architecture that the second device currently supports and/or prefers, and the second information is used to indicate architecture information of a second protocol architecture that a first device currently supports and/or prefers.
