Corresponding equipment and a computer program product are also provided. In deciding whether handover is needed based on capacity, a threshold for received signal code power may be used in addition to the metric for capacity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency quality criteria for inter-frequency handover in a TD-CDMA communication system","description":"A method for determining whether to perform handover of a UE apparatus to a candidate cell and carrier frequency of a TD-CDMA telecommunications network (such as a TD-SCDMA network) based separately o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520640","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.
