Temporary Identifier Characterization in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition to LTE radio technology from disparate 3GPP access technologies like UMTS and GPRS poses operational challenges due to the need for mapping temporary identifiers, which is non-backward compatible, leading to substantial network re-planning and increased costs for network operators with existing radio technology deployments.
Innovation Solution
A system and method that enables user equipment (UE) to generate temporary identifiers and classifiers that distinguish between different radio technologies, allowing serving nodes to identify logical addresses without restrictions, thereby facilitating seamless transitions and reducing the need for network re-planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If temporary identifiers are mapped between disparate radio technologies according to 3GPP LTE Rel. 8 standards, then interoperability between LTE and legacy networks is improved, but network complexity and re-planning requirements increase substantially
Solution Approach 1:
The patent introduces a classifier as an intermediary element that is appended to the temporary identifier. This classifier indicates whether the TI is from LTE or legacy radio technology, allowing the network to distinguish and route appropriately without requiring complex mapping logic throughout the entire network infrastructure.
Solution Approach 2:
The temporary identifier structure is segmented into two parts: the original TI value and an appended classifier. This segmentation allows the classifier to carry specific information about the TI's origin (LTE or legacy), enabling simplified processing at receiving nodes without requiring full reconstruction or complex interpretation of the entire identifier.
2Reliability
If Location Area Codes are restricted to specific domain values to comply with 3GPP LTE Rel. 8 standards, then protocol compatibility is improved, but network deployment flexibility and coverage area are reduced
Solution Approach 1:
The patent adds an additional dimension to the identifier structure by appending the classifier to the TI. This extra dimension allows the system to maintain the original LAC value space used in legacy networks while simultaneously ensuring LTE protocol compatibility through the classifier indicator, effectively resolving the conflict without restricting LAC values.
3Adaptability or versatility
If mapping procedures are implemented for temporary identifiers across different radio technologies, then network transition capability is improved, but operational costs and service disruption during transition increase
Solution Approach 1:
The classifier is prepared and appended to the temporary identifier in advance, before the identifier is used in network communications. This preliminary action ensures that when the identifier is received by network nodes, the classification information is already available, eliminating the need for complex real-time analysis and reducing operational overhead during network transitions.

AI summary
System(s), device(s), and method(s) are provided to characterize a temporary identifier for user equipment (UE) in telecommunication procedure(s) in a wireless communication network. Based on radio technology of at least one serving node that enables at least part of the telecommunication procedure(s), the UE generates a TI and a classifier that discloses the type of the TI. The classifier enables distinguishing a TI value in a first radio technology from a TI value in a second radio technology. In addition the classifier enables a serving node that receives the classifier to identify a logic address of a disparate serving node without restriction in backwards compatibility amongst radio protocols utilized by the wireless communication network.
