re constructed. It is their ability to improve mobile quality, reliability, interoperability, service support, and data bandwidth that will dictate the mobile world's advancement. Their role is to supply and continuously update their network equipment in support of new services and new network build-out. Service platform vendors and developers. Mobile services, both voice and data, already have advanced significantly in just a few years. From simple voice we now have advanced voice services, such as conferencing, forwarding, voice mail, and caller ID. We also have Web access, e-mail, short message service, paging, and more. As more bandwidth becomes available on mobile networks, the question becomes "what can we do with it?" Service platform vendors are the players building the systems that provide or enable most of the value-added services available on mobile networks. In many cases, mobile IICs develop service platforms and applications in-house, making them developers as opposed to vendors. Backhaul transport. There is a question the 21st century four-year-old might ask, and it might go something like this: "Daddy, when you talk in your cell phone, it goes to the tower. But where does it go from there?" It's easy to forget that the mobile network is not entirely wireless. Though the most visible parts of a mobile network are the giant towers and accompanying bunker-like network sites, these are merely traffic collectors. Traffic is backhauled from these sites on landline circuits, often leased from NSPs, CLECs, or ILECs. Mobile providers rely on other IICs to move traffic between their network sites. They are dependent on, for example, an ILEC's The Ultimate Guide to Building and Delivering OSS/BSS cooperation in provisioning and delivering the circuits they need to support new network build-out. OSS. We have looked at a mobile IIC's service delivery processes, but their OSSs also play a role in relationships with resellers and retailers. A resellers' customer should receive the same network service as any oth
