Standards of LBS (3/3) n Standards are Important to LBS Providers With open interfaces, applications can access many sources of content and services 6

Brief History of Standards (1/2) § With pahase I architecture model, most carriers/operators took an approach in which they simply opened up prestandards interface access to their network MPC/GMLC to all spatially enabled applications residing outside the network firewall in the IP domain. Approach for Carrier/Operator LBS Architectures 7

Brief History of Standards (2/2) § Due to the integration problems encountered with the Phase I approach, carriers/operators chose to implement two additional components within the core LBS architecture model § Phare II model ensures that the carrier/operator has complete control over how any application developer interfaces to the core network, and it dramatically reduces implementation costs Approach for Carrier/Operator LBS Architectures 8
