Document Type and Number:
WIPO Patent Application WO/2023/153841
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of operating a User Equipment, the UE being operable in a first mode or a second mode, and being further operable to communicate with a telecommunication network, wherein in the first mode (EPS/S1) if: the UE receives a SERVICE ACCEPT message; the UE has set a Control plane service type of a CONTROL PLANE SERVICE REQUEST message to "mobile terminating request" and an "active" flag in the Control plane service type Information Element, IE, to 0; User Plane, UP, radio bearers have not been set up; and the CONTROL PLANE SERVICE REQUEST message was sent from EMM-IDLE mode, then the UE starts a timer to guard a time during which the UE remains in connected mode; and in the second mode (5GS/N1) if: the UE sends a CONTROL PLANE SERVICE REQUEST message; the UE did not set a Control plane service type IE to "emergency services fallback"; the UE has not included an Uplink data status IE in the CONTROL PLANE SERVICE REQUEST message, or the UE has included the Uplink data status IE in the CONTROL PLANE SERVICE REQUEST message but a received SERVICE ACCEPT message indicates that no user-plane resources of any PDU sessions are to be re-established, then the UE starts a timer to guard a time during which the UE remains in connected mode.
