A next step (306) includes identifying a region that covers all location data. A next step (310) includes dividing the region into smaller blocks, where each block constitutes a Hidden Markov Model state. A next step (312) includes determining a distance between blocks, to be used in a varied continuous probability distribution to determining a state transition probability of each block to represent a likelihood of the MS moving to any one block. A next step (314) includes using a univariate continuous distribution as a function of a distance between each block and a raw location data. A next step (316) includes finding a most likely state/block sequence of the MS motion using the HMM state transition probability and the univariate continuous distribution as the location of the MS."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Real-time location estimation of a mobile station in a wireless communication system","description":"An apparatus and method is provided for real-time location estimation of a mobile station (MS) on a map of roads using non-Global Positioning Satellite location data (300) of the MS and includes a ste","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489117","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
