11、 38 39 40 Preface These technical requirements form a compatibility standard for 800 MHz analog cellular mobile telecommunications systems. Their purpose is to ensure that a mobile station can obtain service in any cellular system manufactured according to this standard. These requirements do not ad
12、dress the quality or reliability of that service, nor do they cover equipment performance or measurement procedures. To ensure compatibility (see Note l), it is essential that both radio-system parameters and call-processing procedures be specified. The speech-filtering, modulation, and RF-emission
13、parameters commonly encountered in two-way radio systems have been updated and expanded to reflect the unique radio plan upon which cellular systems are based. The sequence of call processing steps that the mobile stations and base stations execute to establish calls has been specified along with th
14、e digital control messages and analog signals that are exchanged between the two stations. The base station is subject to fewer compatibility requirements than the mobile station. Radiated power levels, both desired and undesired, are fully specified for mobile stations to control the RF interferenc
15、e that one mobile station can cause another. Base stations are fixed in location and their interference is controlled by proper layout and operation of the system in which the station operates. Detailed call-processing procedures are specified for mobile stations to ensure a uniform response to all
16、base stations. Base station call procedures, like power levels, are not specified in detail because they are a part of the overall design of the individual base system. This approach to writing the compatibility specification provides the base system designer with sufficient flexibility to respond t
17、o local service needs and to account for local topography and propagation conditions. The basic radio-system parameters and call-processing procedures embodied in the compatibility specification were originally derived from the Chicago and Baltimore- Washington developmental cellular systems and inc
18、lude certain additions and modifications gained by experience with the operation of commercial systems. As commercial systems evolve there may be a need for additional capabilities primarily in the area of call-processing procedures and new system features. It is important that evolutionary changes
19、be readily accommodated. To that end, these technical requirements have been organized into six general sections. Alterations to $2 and $3 can affect fundamental mobile station - base station compatibility. All other sections may be altered without affecting basic compatibility. The following is a s
20、ummary of each section: 1. General. This section comprises a list of brief explanations of terms, processes, and functions used in these requirements. Since it is the intention of these requirements to permit great latitude of system configurations and the implementation of system features, only tho
21、se items required for compatibility have strict definitions. Other items may be interpreted to fit the needs of manufacturers and system operators. For example, control channels may be implemented with either combined paging/access functions or as separate paging and access channels. i Copyright Ele
