At a first time when the terminal is within a given locale, the time of receipt of signals received by the terminal from a plurality of the transmitters relative to a reference or each other are measured to create a first set of receive time offsets. At a second time, a second set of receive time offsets is measured. Change(s) in receive  time offsets is/are calculated, and change(s) between the first and second times in transmission time offsets of the signals transmitted by at least one transmitter is/are obtained to determine movement indicators that are compared with threshold valuets to determine whether the mobile terminal has moved outside the locale."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for determining whether a mobile terminal has moved outside a given locale","description":"To determine whether a mobile terminal of a communications system has moved outside a locale, the terminal measures relative time offsets of signals received by the terminal from transmitters of the n","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472971","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.
