WIPO Patent Application WO/2023/191438
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method, for a first user equipment (UE) in a network including the first UE and a second UE, wherein the first UE is configured to operate as a relay node between the second UE and the network is provided. The method includes receiving, from the second UE, a first message to request establishment of a direct link between the second UE and the first UE, and if a certain condition is satisfied, sending, to the second UE a second message rejecting the request, wherein the condition includes the request is for relaying, congestion control is activated at the first UE, a relay service code (RSC) included in the first message corresponds to a data network name (DNN), and the first UE, to meet the request, needs to perform a protocol data unit (PDU) session establishment procedure for the DNN and/or S-NSSAI.
