摘要

EMBODIMENTS HEREIN RELATE TO A METHOD IN A RELAY NODE (10) FOR ACQUIRING INFORMATION ABOUT A TYPE OF A RADIO NETWORK CONNECTION BETWEEN A DONOR RADIO BASE STATION (12) AND A RADIO BASE STATION (14). THE RELAY NODE (10) AND THE DONOR RADIO BASE STATION (12) ARE COMPRISED IN A RADIO COMMUNICATIONS NETWORK AND THE DONOR RADIO BASE STATION (12) IS SERVING THE RELAY NODE (10). THE RELAY NODE (10) RECEIVES A MESSAGE FROM THE DONOR RADIO BASE STATION (12), WHICH MESSAGE IS INDICATING A TYPE OF RADIO NETWORK APPLICATION PROTOCOL, WHICH TYPE IS RELATED TO A TYPE OF THE RADIO NETWORK CONNECTION BETWEEN THE DONOR RADIO BASE STATION (12) AND THE RADIO BASE STATION (14). THE RELAY NODE (10) DETERMINES THE TYPE OF THE RADIO NETWORK CONNECTION BASED ON THE TYPE OF RADIO NETWORK APPLICATION PROTOCOL INDICATED IN THE MESSAGE. THE RELAY NODE (10) ALSO STORES THE TYPE OF RADIO NETWORK CONNECTION IN RELATION TO THE RADIO BASE STATION (14) FOR SELECTING THE TYPE OF RADIO NETWORK CONNECTION WHEN LATER COMMUNICATING WITH THE RADIO BASE STATION (14).
