US 2026/0255226 A1 · SERVICE CONTINUITY DURING AN APPLICATION CONTEXT RELOCATION PROCEDURE

Abstract

The disclosure pertains to a method implemented in a Wireless Transmit/Receive Unit (WTRU) for service continuity during an application context relocation (ACR) procedure. The method includes determining, by the WTRU, one or more local area data network (LADN) data network names (DNNs) that require service continuity. The method additionally includes indicating, to a network by the WTRU, the LADN DNNs that require service continuity. The network is configured to use the list to maintain a protocol data unit (PDU) session toward a source LADN DNN, after the WTRU leaves a service area of a source LADN, while ACR is being executed and release the PDU session when the ACR is complete.

Dependent claims

A wireless transmit/receive unit (WTRU) comprising a processor and memory, the processor and memory configured to:

establish a first protocol data unit (PDU) session associated with at least a local area data network (LADN) data network name (DNN), the LADN DNN being associated with a first service area;
detect that the WTRU re-located to a second service area, wherein the second service area is not supported by the LADN DNN;
send a request to establish a second PDU session associated with at least a DNN, wherein the request to establish the second PDU session indicates that the first PDU session should remain active for a duration;
and
utilize the first PDU session associated with the LADN DNN while operating in the second service area;
and
release or deactivate the first PDU session after the second PDU session has been established.
