The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise connecting to the NR/5G network; communicating a Protocol Data Unit (PDU) Session identity/identifier (ID) identifying a PDU Session with the NR/5G network; communicating data of the PDU Session with the NR/5G network; disconnecting the NR/5G network, connect to the LTE network and performing a tracking area update (TAU) procedure with the LTE network; disconnecting the LTE network and connect to the NR/5G network, after performing the TAU procedure; and communicating the PDU Session ID identifying the PDU Session with the NR/5G network, when disconnecting the LTE network and connecting to the NR/5G network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and method of handling a PDU session in inter-system mobility between a LTE system and a NR/5G system","description":"A communication device for handling mobility between a new radio (NR)/fifth generation (5G) network and a long-term evolution (LTE) network comprises a storage device for storing instructions and a pr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10470199","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.
