Gestión de la mobilidad. (Vicente Casares)

This session was a continuation to the last session. We picked up from where we left by covering the last two technologies of the last session's programme: WIMAX and WLAN.

From WIMAX (OFDM) we covered the packet-stucture and the MAC layer including the 4+1 service types for QOS. Then we continued to WLAN of which we saw the OSI-7 layered technical architecture, the MAC layer and the packet management solution (DIFS, PIFS and SIFS). All of this was for me recapitulation of what I had just went through in the fall's Redes Publicas I course.

Next we stepped into today's actual subject - Mobility management (Which actually includes the above mentioned packet management solution). In a short time we covered quite well the architecture used in tracking mobile stations used in GSM. We also skimmed through very quickly the micro- and macro-mobility subject in the case of all-IP/UMTS mobility management. Finally we discussed the general idea of cellular IP.
