Location-based service platform architecture for wireless mobile users in convergent networks

Current communications are not only by voice but also carriers are capable to use their networks to transmit data and video, resources that customers are using more and integrating phenomenally fast to their daily lives. Wireless companies have a trouble in their hands, competition and technologies are cheaper than what they were in the 90’s, so, increasing fees are not on the table for discussion. Then, they have to offer other services without impacting their customers, attracting them and add value to their networks. Current cellular customers demand new features delivered by their cellular companies. Different services have been deployed over the years to satisfy customer’s needs, such as SMS, mobile Internet, mobile tv, etc. Other kinds of services that have appeared on the market are those named as LBS (Location-Based Services). LBS are beginning to show that they may increase the value perceived by customers when they choose a company. Moreover, they are deployed to satisfy existent requirements and capable to be personalized according to user preferences through applications contained in mobile devices. These services are based on positioning information gathered by mobile networks and delivered to service providers, the owners of technological platforms in charge to process data and requests and deliver value-added information in return. The increasing LBS market has been aided by the use of the Internet Protocol (IP) and the development of application protocols such as SMPP, SUPL and MLP. These protocols are beginning to be used not only inside the carriers’ core networks but also on users’ mobile terminals, increasing not only market penetration but also the development of different content. Furthermore, we can mention that IP is merely an ally and not the final solution for the LBS platform in our case. Mobile providers in some cases prefer to become merely carriers and establish agreements with service providers instead of deploying these services in home and invest capital that they are not willing to spend either. Nevertheless, carriers have the advantage to be able to add to their network a wide variety of services because they can get agreements with many services providers. This is also possible thanks to the compatibility of certain technologies and protocols existing in the market. This work shows a platform developed to attend different requests from different networks, accepting interfaces as SMS, WAP and HTTP. The general concept proposed considers storing information and flow control over the service provisioning, different characteristics to others proposed by other authors. This work’s main characteristics are inner flow control and profiling done by an entity named Central Control Unit (CCU) helping storing useful data considered for further service provisioning managed and controlled by a server named MCS (Management and Control Server). The MCS is also defined for gathering information gotten from the carriers’ databases. This information is accessed by the SEE (Service Execution Environment) using clients defined to request the necessary information managed by the MCS and be used by the SEE to deliver value-added information results to mobile users.
