Said method for detecting a duplicate address comprises: the mobile station sends a request message to the first network element; the first network element generates and sends a first message to the mobile station upon reception of said request message, said first message designating an explicit address configuration and including prefix information; the mobile station checks out the explicit address configuration, generates an address based on said prefix information and sends a message containing the generated address to the first network element for indicating that the mobile station requires registering the generated address with the first network element; and the first network element creates an entry for the mobile station if the generated address is not found in its address table, or generates and sends a second message to the mobile station for indicating that the generated address is a duplicate address if it is found in its address table and discards data packets with the duplicate address sent from the mobile station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting a duplicate address, mobile station, network element and communication system","description":"The present invention proposes a method for detecting a duplicate address, a mobile station, a network element for controlling access of a mobile station to a wide area network and a communication net","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488557","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.
