US 2026/0101407 A1 · METHODS, NODES AND COMPUTER READABLE MEDIUM FOR RELAY CONNECTION ESTABLISHMENT

Abstract

There is provided a method at a second user equipment (UE2) comprising receiving, from a first UE (UE1), a relay request message indicating a relay request of UE1. The relay request is for a relay service requested by UE1. The relay request message comprises an indication of a Public Land Mobile Network (PLMN) to which UE1 is subscribed. The method comprises determining that the relay request can be accepted by UE2 in at least one case where: the UE2 is authorized to support the relay service; the relay service is allowed by a current cell of UE2 served by a network node; UE2 is currently in a Radio Resource Control connected state; UE1 subscribes to a same PLMN as UE2; or the network node has provided relevant Access Stratum configurations to UE2. The method comprises transmitting a relay response message to UE1 based on a result of the determination.
