The mean number of hand-offs is a fundamental performance measure in any mobile system, as it directly relates to the signaling load in the network as well as to the delivered QoS. As the mobile services are evolving from simple cellular voice calls towards media and data sessions, and as cellular providers are reinventing their businesses by incorporating third party services, the hand-off rate will even play a more pivotal role. This is because future sessions are expected to last longer than voice calls and users are more likely to roam into other networks.
