A communication channel management unit (122) ranks communication channels to be used for communication with the PHS terminal (13) based on a monitoring result by the carrier sense unit (121). When a request for acquiring or a request for switching to a communication channel to be used for communication with the PHS terminal (13) is made, a communication channel switching control unit (123) preferentially selects and allocates a communication channel ranked high as a communication channel where radio wave interference is not occurring from among usable communication channels ranked and managed by the communication channel management unit (122)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital cordless telephone system for business use, interference avoidance method, and non-transitory computer-readable recording medium storing interference avoidance program","description":"A carrier sense unit (121) of a PHS base station (12) periodically carrier-senses nearby radio waves and monitors whether radio wave interferences with a communication channel to be used for communica","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628997","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.
