Title:
ユーザ装置、セッション管理機能及び通信制御方法
Document Type and Number:
Japanese Patent JP7441596
Kind Code:
B2
Abstract:
A communication measure is provided that causes a PDU session established in a 5GS to return to the PDU session in an original state after the PDU session established in the 5GS is moved (handed over) to an EPS and then moved (handed over) to the 5GS again. In addition, according to the present invention, a communication measure is provided that causes a PDN connection established in the EPS to return to the PDN connection in an original state after the PDN connection established in the EPS is moved (handed over) to the 5GS and then again moved (handed over) to the EP. In addition, according to the present invention, a communication measure is provided that allows smooth mobility of the UE in an idle mode between the 5GS and the EPS. Further, a communication measure is provided that performs a handover between the 5GS and the EPS smoothly.
