Abstract
We propose a shift in the cellular positioning system
paradigm that enables cellular providers to better meet the
location-based services (LBS) needs of cellular users using only existing
network infrastructure. Focusing specifically on current 4G
and next-generation 5G technology, we outline a novel positioning
system architecture, which utilizes the timing advance parameter
to generate continuous position estimates with modern accuracy,
minimum overhead, and improved latency. We highlight key limitations
in existing positioning methods—excessive data overhead
in positioning management traffic and poor network infrastructure
geometry—through a review of the Third Generation Partnership
Project’s positioning system architecture evolution. We then
present our alternative architecture, and demonstrate how our proposed
system methodology mitigates these concerns, by comparing
our proposed architecture with the existing ones. Finally, through
numerical study, we establish that our methodology is able to meet
and exceed federal emergency services standards and, thus, also
many common LBS service requests. Our architecture is agnostic
to mobile devices’ capabilities and has the potential to alleviate
computational burden at the mobile device while simultaneously
improving data throughput and latency through reduction of control
overhead
