The realization of communication services over 5G needs resource sharing as a way to achieve network coverage. To do so, it is necessary to consider security access mechanisms to regulate how interconnections are made. The existing models do not address all the needs inherent to the 5G architecture, such as access control mechanisms, multi-tenancy, multi-domain and multiple security levels. This position paper presents the state of the art of access control models and their application in 5G networks. Then, points out problems that are not addressed and establishes the conditions that such access control scheme must obey in order to be suitable for its utilization in the 5G system.
