Abstract
An apparatus used in a UE includes processing circuitry and memory. To configure the UE for a DNS resolution, the processing circuitry is to encode UL data for transmission to a first EAS via a first data path. The first data path includes a first UL CL UPF and a first PSA. A NAS SM message received from an SMF node is decoded. The NAS SM message includes an EAS rediscovery indication and a list of FQDNs associated with the first EAS. A DNS resolution procedure with a DNS server is performed in response to the EAS rediscovery indication, to obtain an IP address of a second EAS. The DNS resolution procedure is based on the list of FQDNs, and a second data path to the second EAS is established based on the IP address.
