Random Access Message Dedicated Information for Wireless Device Connection
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
