The LBS Marketing Twist

By: Jonathan Spinney, Product Specialist, SignalSoft Corporation

The phrase Location-based Services (LBS) is abuzz in the GIS industry. It seems everywhere one looks these days there is some mention of a new product line or initiative focused on mobile lifestyles and delivering location-based information to mobile devices. Wireless industry analyst- identified regression models, the US FCC 911 mandate schedule, and market penetration propensity predictions have all fueled the market and positioned the LBS space as the next big niche for GIS, and the proverbial ‘killer app’ for the wireless telecommunications industry. The convergence of conventional wireless networks with Internet technologies has spawned this new market segment for GIS companies who have historically been uninvolved in the real time call processing aspect of wireless networks.

Prior to the Signaling System 7 (SS7) and IP convergence, and the resulting introduction of a new GIS market cavity, GIS companies were limited to entering network operator environments with support oriented GIS service tools. These tools have historically assisted network operators with managing their geographic assets, planning network build-out, and analyzing geographic market trends. These tools were, and still are, well-received and implemented operational components of any typical network operator environment. If you ever have the chance to visit a Carrier site, your likely to find some type of GIS handling offline activities unrelated to call processing - whether it be managing base station locations, analyzing propagation data, or identifying market trade areas. While all of these operational activities have required some derivative of a geographically based management system, location-based services on the other hand introduce a new and untapped domain for GIS players - the online transaction and call- processing realm of the network operator environment.

LBS have recently received much hyped attention, evident through redundant GIS industry collateral and advertisements. Most of these advertisements appear identical, and most GIS companies appear to be claiming identical LBS application capabilities. The LBS topic is trendy, and commentary and/or advertisements appear monthly in most GIS industry publications. In talking with GIS industry players and my academic colleagues, there is a perceived notion that LBS is a new and exciting endeavor. This notion is however a misconception. LBS in reality, has been around for at least five years. Newcomers to LBS, of which GIS companies are significant sources of new contribution, have identified LBS as a space they can enter through their spatial technology expertise. In fact, the potential is assumed to be so promising, that complete subsidiary programs by GIS companies have been launched to focus specifically on LBS alone. The interesting thing is that they appear to be marketed separately from their core business competency - GIS. This is apparent by new initiatives under different company names, further distinguishing their LBS capabilities from their GIS capabilities. Still, and perhaps even more intriguing is that the prominent GIS standards governing consortium OpenGIS have launched a unique LBS-centric standards consortium called OpenLS. Perhaps a natural question one would ask, and one in which my colleagues and I have pondered, is why have GIS companies and organizations distinguished their LBS divisions as independent entities within their organization? There are arguably an extensive slue of managerial and organizational reasons for separating the two, which may be specific to individual company and organization structures concentrating on specific verticals and market segments, but from a technology standpoint the question may be relatively simple to answer.

The advancement of wireless networks from 2G to 2.5G, and eventually 3G, has opened the competitive gates for new and enhanced LBS applications built by GIS companies. The online transaction and call processing participation of GIS/LBS subsidiaries has become realized largely due to these enhanced next generation IP-capable networks. Wireless networks are now capable of standardized protocol interfacing with IP elements outside of the wireless infrastructure built on SS7. Conventional networks based on SS7 have been around a while and LBS applications designed to function on SS7 have been a reality since 1995. However, it is the convergence of SS7 and IP that have made it possible for GIS companies to enter the LBS application domain. GIS companies are likely to be successful in the space largely due to their already well-developed IP-based Internet mapping capabilities. Most GIS companies seem to be targeting this angle because it does not require them to develop SS7 capabilities. A map server application can reside outside of the network and perform all the necessary spatial query and processing needed to deliver content back to the subscriber via XML, cHTML, or WML in the case of WAP services now live in a lot of Carrier networks throughout the world. However, processed content must still pass back through the SS7 infrastructure in order to deliver location information to the mobile subscriber. In addition, these IP-based LBS applications must firstly receive subscriber location from the SS7 infrastructure in order to process the request in the first place. This requires that the SS7 network elements have some sort of location management component. These location management components residing on a network Service Control Point (SCP) are known in the CDMA/TDMA world as the Mobile Positioning Center (MPC), and the GSM counterpart Gateway Mobile Location Center (GMLC).

MPC’s and GMLC’s must firstly, be capable of interfacing with positioning technologies such as TA, TOA, AOA, TDOA, GPS, etc. in order to position a subscriber; and secondly, capable of transferring that X,Y subscriber location to the wireless network SCP where it can then route the data to an IP-based application for spatial processing. An alternative to routing the call and position data to an IP-based application is to build the applications to run directly on the SCP. This is not a trivial a task - one in which GIS companies have steered clear of. GIS companies don’t specialize in building wireless network components like an MPC or GMLC, but these elements are key for making location services a reality. The alternative is for the subscriber to enter their location into their mobile device which is an unlikely viable solution.

So what does all this mean, and what is the original point? I asked the question “why have GIS companies and organizations distinguished their LBS divisions as independent entities within their organization?” GIS companies may have segregated their core competencies of GIS from LBS because it may be a more appealing catch phrase for wireless professionals. It is a phrase that wireless network operators are likely to interpret and embrace because it implies mobility, and if GIS companies are implying understanding mobility management, then they must be keen to what’s going on in wireless networks. The fact is, GIS companies are really not doing much more then taking their existing Internet mapping capabilities and wireless enabling them through XML formatting. Others, who specialize in SS7 and GIS, have been able to develop these technologies for the last five years because of their IP-independence and SS7 compatibility. The wireless network operators have made LBS possible for GIS companies, and GIS companies have put a twist on their marketing approach to appear more savvy in the LBS space. No more, no less. One thing is for sure, all involved in either building GMLC’s or MPC’s, building spatial processing Applications, the interfaces between the two, or all of them, are likely to capitalize on their investments in the “new” theatre of the LBS domain.
