su h servi es, the optimum interoperability among servi e platforms is riti al
due to the variety of elements at the servi e layer that are involved in ontext-

development eorts, Web servi es te hnology is onsidered a must to make
su h servi es happen in a minimum time to market. In this hapter, the
prin iples to deploy ontext-aware servi es in operator networks are presented.
In addition, a su essful ase is des ribed in detail, implemented with the
