Mortive - It is claimed as one of the most effective technology which enable network operators to offer Location Based Services for their subscribers speedily and economically. As the empiric revealed the reluctant of network operators to implement LBS is basically because of the cost and complexity of modifying Control Plane (C-Plane, some refers as positioning) network elements and protocols. Thus SUPL facilitates network providers to achieve this with least impact on C-Plane.
Overview - SUPL was developed by OMA (Open Mobile Alliance - http://www.openmobilealliance.org/), which is organized to bring in open standards that ensures interoperability across devices in LBS industry.Therefore it supports location identification regardless of the location server used by the mobile carrier. Further, it has designed to facilitate A-GPS (Assisted GPS), which is regarded as one of the most efficient positioning mechanism.
Architecture of SUPL consists of two elements, viz. SET (SUPL Enabled Terminal) and SLP (SUPL location Platform). Set is a mobile phone or PDA configured to support SUPL transactions.SLP is a server that handles user authentications, LB requests, roaming and charging etc.

HLR - Intro
Home Location Register is the main database of permanent subscriber information.
There can be one or more HLRs in a single Publinc Mobile Network. It depends upon number of mobile subscribers, capacity of the equipements, organisation of network infrastructure etc. One core information stored in a HLR, specially related to LBS, is the location of a Mobile Subscriber (MS). Thus it enable HLR to route calls to those subscribers managed by that particular HLR. IMSI (International Mobile Subscriber Identity) and MSISDN (Mobile Subscriber Integrated Services Digital Network Number) are two numbers stored in a HLR attached to each subscriber.
Other than that HLR stores following information.
1. Current Location information (VLR number)
2. GSM services subscribed or given
3. Call divert settings
4. Service limitations

LBS - Industry environment
As LBS is still in a rapidly growing stage, it opens up a big market as well as number of technology integrations. Service platforms, mobile terminals, web services are leading aliases that energize LBS and Vice-versa. Since most of the mobile networks operates as service providers, it enabled them to become the providers of LBS as well.
But, to become this market more expandable, popular or profitable, few more players also need to play their roles. Contecnt providers, application developers, framework and middle-ware providers are those other players behind the curtain. Thus to come-up with a balanced or uninterrupted LBS service there should be a great deal of techno compromisation amongst them.

LBS - A Value Addttion
Next few posts on this topic will be dedicated to, but not restricted to, discuss about usage of LBS at present, market players,Infrasture Needs and trends in this technology. Lets start up with the ways that LBS been used today.The main service areas powered by LBS are tracking and
navigating, emergency services,advertising, localized service provisioning from operators, geo-base information provisioning such as hospitals, resturants, air ports etc. and in M-commerce.
Now lets see how LBS become a value addition to those above mentioned services. when an operator/ service provider got a news to circulate about offers in supermarket chain but in few suburbs only what normally happens is sending messages to all subscribers at large. But LBS will enable operators to select the subscribers in that particular area and forward the message. Thus it will become more focused, useful and highly cost-effective.
