New Standards on Mobile Communications

The new generation of mobile communications, characterized by the ubiquity of the services and the heterogeneity of the technologies, has new needs: it shows the deficiencies of the present standards in several aspects and arise others that cover the new requirements. In this work, on the one hand, the deficiencies in security aspects of the current standards, and on the other hand, two new works that are being carried out at the moment are going to be shown. One of them is the UMA (Unlicensed Mobile Access) standard, which has begun to be implemented, and another one, the IEEE 802.21 or Media Independent Handover (MIH), which is still under development. Although a general analysis is going to be carried out, covering all the aspects, the emphasis is going to be focused in security aspects (authentication and authorization, access control, users’ identity and content of the data protection, etc.).
