Mobility management for wireless systems with unreliable backhaul links

We consider a wireless system with unreliable microwave backhaul links. Since the links may be disconnected, the location update procedure may be incorrectly exercised, which results in misrouted calls. This paper proposes an analytic model to derive the misrouting probabilities as functions of the link disconnection time distribution. These equations can be used as the design guideline to select the microwave equipment for the wireless system.
