In addition, a system for implementing an NP service is provided, including an NP database and a switching device. Two types of NP databases are also provided. With the present invention, each NP database only needs to store partial NP data, which lessens the load of each NP database in storing and updating NP data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for implementing number portability service","description":"A method for implementing a number portability (NP) service includes: by a local NP database, receiving a called user number from a switching device; determining an NP database storing NP data of the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8498400","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.
