Purpose of the paper is to propose to better exploit the commonalities that could exist between users evolving in a cellular network in order to bring some gains in terms of spectral efficiency and Quality of Service (QoS) provided. Fundamental assumption is that in a near future several radio access technologies (RATs) will become available to the users and thanks to reconfigurable terminals, these users will be able to intensively use these various RATs, The evoked commonalities between users rely on two major cases. Whether considered users respond to a common kind of profile or at least have the same requirements, whether a concerted way of acting between a finite amount of users exists. As a matter of fact both cases imply the creation, the management and the termination of a group of users, i.e. Ad Hoc networking but on a radio point of view and including the capabilities of Software Defined Radio. It becomes so possible to offer a maximized QoS to the users group in responding in a sharper way to what they expect but also to release the native cellular network where users were when the group creation occurred. On operator side, result would be a more efficient Radio Resource Management (RRM) offering a higher level of flexibility and always the possibility to reach any user in a transparent manner through the group’s master node. Possible range of applications seems to be quite wide considering both kinds of groups presented hereafter.
