Abstract: A wireless communication system includes an end user device (604) and a plurality of access nodes (607, 608). For adaptive communication service access, the end user device is associated with an End User Module (601) and the access nodes are associated with Access Manager Modules (609, 611), and for the selecting one of a plurality of communication channels, a negotiation procedure is performed, that includes the steps of: either the End User Module (601) sending (624, 625) a Call For Proposal to one or several Access Manager Modules; or an Access Manager Module (609, 611) sending a connectivity offer to an End User Module (601); the End User Module (601) and at least one Access Manager Module (609, 611) negotiating the characteristics of a connection by iteratively sending each other messages (626, 627, 628, 629).
