Solution Overview

Problem

The performance of access control procedures in wireless communication systems, particularly in LTE, needs improvement to enable faster and more flexible device access during the transition from an idle state to a connected state, as existing methods are inefficient in establishing connections quickly.

Innovation Solution

A method and device that transmit a random access message carrying dedicated information and indication information to optimize the access process, allowing the first device to access the second device more quickly and flexibly by pre-configuring or negotiating resources for information transmission, thereby reducing the need for uplink resource allocation and minimizing delay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the UE transmits a random access message to establish a connection from idle state, then the connection establishment is achieved, but the access delay is excessive and the process is inefficient

Engineering Contradiction:
Improveaccess speedVSAvoidaccess delay
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring dedicated information and indication information in the random access message before the actual connection establishment process. The first device prepares the dedicated information (identity, service type, resource preferences) and indication information (resource allocation requests, configuration parameters) in advance, so that when the random access message is transmitted, the second device can immediately process the connection request without requiring additional back-and-forth signaling exchanges, thereby reducing access delay and improving connection establishment speed

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the traditional random access procedure is used, then the connection can be established, but the access control performance is insufficient and the process is not flexible

Engineering Contradiction:
Improveaccess flexibilityVSAvoidaccess control performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies segmentation by dividing the random access message into distinct functional components: dedicated information (identity, service type, resource preferences) and indication information (resource allocation requests, configuration parameters). This segmentation allows the second device to process different elements independently and efficiently, improving access control performance while maintaining flexibility in handling various connection scenarios

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by dynamically adjusting the content and structure of the random access message based on the specific connection scenario. The first device can modify dedicated information (such as service type indicators) and indication information (such as resource allocation preferences) according to different access requirements, enabling flexible adaptation to various network conditions and service types while improving access control performance

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If the UE needs to transmit additional information for connection establishment, then the connection can be properly configured, but the signaling overhead increases and the process becomes more complex

Engineering Contradiction:
Improveinformation completenessVSAvoidsignaling complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies merging by combining multiple pieces of connection establishment information into a single random access message. The first device integrates dedicated information (identity, service type, resource preferences) and indication information (resource allocation requests, configuration parameters) into one transmission, eliminating the need for separate signaling messages and reducing overall signaling complexity while ensuring complete information delivery

Inventive Principle:
Principle #5Merging (Combining)
