By using the method of the present invention, if the user subscribes to the IP Centrex service and the IN service, no conflict occurs between the IP Centrex service and the IN service, and discount charging is implemented on the intra-group call. A network device and a mobile communication system are also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device, and system for implementing communication services","description":"A method for implementing communication services includes: after receiving a call request, determining whether a user subscribes to an IP Centrex service and an intelligent network (IN) service accord","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8477669","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.
