The AAA server (103) retrieves information identifying a current SGSN (108) currently serving the wireless device (101) in the second network (100b). When the AAA server (103) retrieves authorization information for the wireless device's (101) access to the first network (100a) from a HLR (105), the AAA server (103) indicates the current SGSN (108) as a new SGSN to the HLR (105). The indication is to be interpreted by the HLR (105) as an update of location information or a refresh procedure from the current SGSN (108)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Node and a method for enabling network access authorization","description":"The embodiments herein relate to a method in an AAA server (103) for enabling authorization of a wireless device (101) to access a first network (100a) while simultaneously accessing a second network ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641531","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.
