Zusammenfassung:There is provided a method performed by a master node (MN) comprising: determining a protocol data unit (PDU) session to be served is to be a split PDU session between the MN and a secondary node (SN); generating a request message to be transmitted to the SN to setup PDU session resources on the SN comprising a split session indicator information element (IE) with an enumerated field configured to indicate whether the PDU session is to be the split PDU session. The message is one of a S-Node Addition Request message or a S-Node Modification Request message. The method further comprising transmitting the request message to the SN using an XN application protocol (XnAP).
