Responsive to determining that the network is a hierarchical MPLS-enabled network, the computer system configures a first set of TE Label Switching Paths (LSPs) between each SBC of the multiple SBCs and the single IMS Core site. The computer system configures a second set of TE LSPs between each SBC of the multiple SBCs and each other SBC of the multiple SBCs to form a full mesh. The network further includes multiple user endpoints (UEs). The computer system configures a third set of TE LSPs between each UE of the multiple UEs and an SBC of the multiple SBCs. The UE is configured to use the SBC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiprotocol label switching (MPLS) traffic engineering design for IP multimedia subsystem-based voice over internet protocol","description":"Methods for Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) design for IP Multimedia Subsystems (IMS) include determining that a network is a hierarchical MPLS-enabled network including ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11509574","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.
