The method includes the following steps. In response to a message indicating that the service provider unit uses an access mode of an extended service channel, whether information of the switch ratio is stored in service information of the user unit is searched in the user unit according to geographical information of the service provider unit. If the information of the switch ratio is stored in the service information of the user unit in the searching step, the user unit is set accordingly to enter the access mode of the extended service channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for providing service channel in a vehicular environment, method and system for switching service channel, and computer readable medium","description":"A method for switching service channels in a vehicular environment is provided for performing communications between a user unit and a service provider unit according to a switch ratio between a servi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8515447","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.
