Abstract

<strong>PURPOSE AND SCOPE</strong> <br>Cellular telephony has been adopted by many segments of the business community and has enjoyed strong growth over the years. With this growth has come an increasing recognition that there is a need for a geographically limited capability that offers affordable, light-weight, portable/mobile communications. The concept raised by this need is that certain specialized services need to be offered exclusively to a set of users called a "closed user group." <br>Typically, the users of such systems might be expected to be able to access PBX/CENTREX^TM features in the same way as they would on wired PBX/CENTREX^TM terminals. It is also expected that as systems and features designed for closed user groups evolve, there will be a need to support other applications, such as those in residences, campuses, sports facilities, etc. It is further expected that there will be a need to allow subsets of the closed user group subscribers to use their handsets on the macrocellular network. <br>This standard provides the minimum specifications for an air interface that will support such a closed user group with limited geographic capability within a macrocellular service area. <br>The purpose of this standard is to provide an air interface specification that allows wireless 800 MHz cellular services to be delivered to a closed user group. The closed user group may be provided with special sets of service features, or specialized charging arrangements, or combinations of both. <br>It is intended that this standard will support systems that conform to the classification of "auxiliary system" of a cellular system as described in the FCC Report and Order for Docket 87-390. As such, the systems which employ this standard will be expected to avoid interference to or disruption of the macrocellular system(s) in the area where they are operating. <br>Also, in conformance with applicable regulations, it is intended that auxiliary systems employing this standard will be operated under the auspices of the appropriate licensed cellular provider.
