Positioning for performance enhancement in shared LTE and HSPA networks

Efficient radio resource management in wireless network systems is increasingly becoming a necessity as current trends drive towards increased number of users and bandwidth hungry applications and services. In this paper, two concepts for targeting this capacity challenge are addressed: cooperative and localization based radio resource management. In cooperation we refer to the concept of a sole entity responsible for managing radio resources for heterogeneous networking environments, and herein we explore an HSPA with an overlay LTE/network. For optimized decisions in such an environment, utilizing mobile positioning information seems to show enhanced system performance. This paper investigates the application of suitability based RAT selection using positioning information for enhanced throughput performance in heterogeneous networking environments. The results clearly show that, for optimized decisions in such an environment, utilizing mobile positioning information clearly shows enhanced system performance.
