The cellular phone terminal comprises, in addition to the cellular phone function section, a cellular phone network transmitter/receiver section, a wireless LAN transmitter/receiver section and a wireless LAN connection control section, an SSID•MAC address management section connected to the wireless LAN connection control section and the cellular phone network transmitter/receiver section. The SSID•MAC address management section is allocated by a MAC address management server one or more temporary MAC addresses together with their time limit by way of the cellular phone network transmitter/receiver section and a cellular phone base station and the temporary MAC addresses are used when conducting a search for wireless LAN base stations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cellular phone terminal having built-in wireless LAN, cellular phone system and personal information protection method therefor","description":"Disclosed are a cellular phone terminal, a cellular phone system and a privacy protection method therefor that enable to prevent leakage of private information from the communication data when conduct","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503369","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.
