Temporary Identity Segmentation for 5G Random Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless telecommunications systems face challenges in efficiently supporting a wide range of devices with different data traffic profiles and coverage requirements, particularly in 5G networks, due to limitations in terminal device identification and network slice management.
Innovation Solution
The proposed solution involves a method where only a portion of the temporary identity is included in the initial message during the random access procedure, with additional information transmitted separately to ensure contention resolution and network slice identification, allowing for increased device identification and network slice management without compromising reliability or coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the complete temporary identity is included in the initial message during random access procedure, then device identification accuracy is improved, but message size and network overhead increase
Solution Approach 1:
The temporary identity is divided into two parts: a first portion included in the initial message during random access procedure, and a second portion transmitted separately in a subsequent message. This segmentation allows the initial message to be kept compact while still enabling device identification through the first portion, resolving the contradiction between identification accuracy and message size.
2Adaptability or versatility
If additional identity information is transmitted separately, then network slice management capability is improved, but communication steps and time increase
Solution Approach 1:
The first portion of the temporary identity is prepared and included in advance in the initial random access message, enabling preliminary device identification. The second portion is then transmitted separately to complete the identification and enable network slice management, reducing the overall time compared to transmitting all information in a single subsequent exchange.

AI summary
A method of operating a terminal device to establish a radio resource control connection with network infrastructure equipment in a wireless telecommunications network, wherein the terminal device is associated with a previously-allocated temporary identifier that identifies the terminal device within the wireless telecommunications network; the method comprising: transmitting a first message to the network infrastructure equipment comprising an indication of a first portion of the temporary identifier; and transmitting a second message, which is separate from the first message, to the network infrastructure equipment comprising an indication of a second portion of the temporary identifier.
