Connection Establishment Request Format Selection for LTE Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Long Term Evolution (LTE) technology is limited by a 48-bit collision resolution message, which restricts the extension of connection establishment request content, making it impossible to meet diverse network environment requirements for connection establishment.
Innovation Solution
A method and apparatus that allow terminal equipment to select from multiple connection establishment request formats based on service requirements, capability requirements, and network conditions, enabling the determination of an appropriate format for sending connection establishment requests, thereby supporting content extension and rapid connection establishment in various environments.

Engineering Contradiction Analysis
1Adaptability or versatility
If a 48-bit collision resolution message is used in LTE, then the connection establishment request can be sent through the random access process, but the content extension of the message is limited and cannot meet requirements of different network environments
Solution Approach 1:
The connection establishment request message is segmented into multiple parts: the original 48-bit collision resolution message and additional content fields. This allows the message to be transmitted in a structured manner where essential identification information is preserved in the collision resolution message while supplementary information is carried in separate content fields, thereby expanding message capacity without disrupting the existing random access procedure.
Solution Approach 2:
The message structure is extended by adding a new dimension - content fields with configurable bit lengths. Instead of being limited to a fixed 48-bit message, the system now operates in an expanded message space where the total message capacity becomes 48 bits plus additional content bits, allowing flexible adaptation to different network environment requirements.
2Productivity
If the connection establishment request message format is fixed at 48 bits, then the random access process can proceed smoothly, but the message content cannot be extended to support diverse service requirements
Solution Approach 1:
The message format transitions from a static fixed 48-bit structure to a dynamic configurable structure. The system can adaptively select different content field lengths (first content field: 1-10 bits, second content field: 1-10 bits) based on service requirements and network conditions, allowing the message capacity to dynamically adjust while maintaining compatibility with the existing random access process.
Solution Approach 2:
The message parameters are changed by introducing configurable content field lengths instead of a fixed format. The first content field can be configured with 1-10 bits and the second content field with 1-10 bits, allowing the total message capacity to vary based on operational requirements while preserving the core 48-bit collision resolution message structure that ensures smooth random access operation.
3Adaptability or versatility
If multiple connection establishment request formats are supported, then rapid connection establishment for different service requirements can be achieved, but the device complexity increases
Solution Approach 1:
The terminal equipment autonomously determines the appropriate connection establishment request format based on its own service requirements and capability requirements without requiring complex network-side configuration or negotiation. This self-service approach simplifies the overall system complexity by eliminating the need for elaborate format selection protocols while still enabling rapid adaptation to different service requirements through local decision-making.

AI summary
A method and apparatus for establishing a connection are provided. The method includes: terminal equipment determines a connection establishment request format adopted when a connection establishment request message is sent from multiple connection establishment request formats; and the terminal equipment sends the connection establishment request message to network equipment according to the determined connection establishment request format. In such a manner, rapid connection establishment for different service requirements in multiple environments may be adapted.
