Solution Overview

Problem

Under the current relay architecture, establishing a connected state for both user equipment and a relay terminal requires significant signaling overhead due to independent connection processes.

Innovation Solution

A method involving terminals exchanging identifiers and network access information to simplify the establishment of connected states, reducing signaling overhead by allowing one terminal to indicate the connected state of both and potentially sharing network access information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user equipment and relay terminal perform independent connection processes, then each terminal can establish its own connected state, but signaling overhead increases significantly

Engineering Contradiction:

Improveconnection establishment reliabilityVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent combines the connection processes of user equipment and relay terminal into a single unified process. The network device establishes a connection with the relay terminal that simultaneously enables the user equipment to enter a connected state through the relay terminal, merging two separate connection procedures into one, thereby reducing signaling overhead while maintaining connection reliability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connection established between the network device and relay terminal serves multiple functions simultaneously: it establishes the connected state for the relay terminal itself and also enables the user equipment to achieve connected state through the relay terminal. This multi-functional connection approach eliminates redundant signaling while ensuring both terminals achieve their connection objectives

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If user equipment and relay terminal perform independent connection processes, then each terminal can establish its own connected state, but the connection process becomes more complex

Engineering Contradiction:

Improveconnection establishment reliabilityVSAvoidconnection process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the connection processes of user equipment and relay terminal into a single unified procedure. Instead of two separate independent processes, the network device performs one connection establishment that simultaneously connects both terminals, thereby simplifying the overall connection process while maintaining reliability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the connection establishment into two distinct scenarios handled differently: when relay terminal is in connected state (simplified process) and when relay terminal is in idle state (standard random access process). This segmentation allows each scenario to be handled with appropriate complexity, reducing overall process complexity while ensuring reliability

Inventive Principle:

Principle #1Segmentation

3Reliability

If user equipment and relay terminal perform independent connection processes, then each terminal can establish its own connected state, but time consumption increases

Engineering Contradiction:

Improveconnection establishment reliabilityVSAvoidconnection establishment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the user equipment obtain the relay terminal's identifier and information in advance during the connection process. This allows the network device to efficiently establish the connection without requiring separate procedures, reducing time consumption while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By merging the connection processes, the patent eliminates the sequential execution of two independent connection procedures. The unified connection process establishes both terminals' connected states simultaneously, significantly reducing the total time required compared to performing separate connection processes

Inventive Principle:

Principle #5Merging (Combining)

AI summary

This application discloses a method for establishing a connected state, a terminal, a core network function, and an access network device. A method for establishing a connected state performed by a first terminal includes: receiving first information sent by a second terminal, where the first information includes at least one of: a second identifier, and network access information; and sending first indication information to a network side, where the first indication information includes at least one of: the second identifier, and a first identifier. The second identifier is used for indicating, to the network side, that the second terminal enters a connected state, and the first identifier is used for indicating, to the network side, that the first terminal enters a connected state.
