While, this type of handover works fine in current systems, where the core network is controlled by a sole operator and thus information about the topology of different networks is available, this type of handover is not suitable for heterogeneous environments, since multiple operators coexist in the core network.
Patients need basic information about how clinical handovers work between the different microsystems involved in their care, and what is expected of them to help ensure high quality handovers.
As a negative point, the unit was perceived as noisy during handover between work shifts.
Thus, the Handover Keying Working Group HOKEYY) tries to reduce the delay caused by the authentication once the mobile user changes its location.
The IETF handover keying working group (HOKEY WG) [4] is currently developing solutions to provide a secure, MIH, also called inter-technology handover.
Robustness to the backhaul latencies and adaptation to the backhaul throughput constraints are other key technical issues, as well as the elaboration of efficient handover algorithms working in an environment composed of unmanaged, small, and dense cells.
For example, Swedish patients noted that when they assumed responsibility for the handover, communication worked better.
Evaluation has shown that the new system of handover is working well but monitoring will be ongoing with evaluation of a larger sample of patients.
More recent evidence studying the effect of 2011 ACGME regulations suggests a decrease in patient safety related to increased numbers of handovers and work compression.
This weekend's Nato summit in Chicago is supposed to cement the handover process and work out how to pay the future bill of supporting Afghanistan.
