A target network for handover is selected using not only a system utility function reflecting user and system parameters but also a history utility function reflecting history information, thereby reducing the number of handovers and enhancing service quality."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handover method and apparatus based on history information in wireless networks","description":"A handover method in a plurality of wireless networks includes selecting one or more candidate networks from the plurality of wireless networks available to a mobile terminal of a user; calculating th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8504037","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.
