Their purpose is to ensure that a mobile stati
10、on can obtain service in any cellular system manufactured according to this standard. These requirements do not address 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
11、-system parameters and call-processing procedures be specified. The speech-filtering, modulation, and RF-emission 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 proce
12、ssing steps that the mobile stations and base stations execute to establish calls has been specified along with the 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. Radiat
13、ed power levels, both desired and undesired, are fully specified for mobile stations to control the RF interference 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 op
14、erates. Detailed call-processing procedures are specified for mobile stations to ensure a uniform response to all 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
15、writing the compatibility specification provides the base system designer with sufficient flexibility to respond to 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 speci
16、fication were originally derived from the Chicago and Baltimore- Washington developmental cellular systems and include 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 prima
17、rily in the area of call-processing procedures and new system features. It is important that evolutionary changes 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 st
18、ation compatibility. All other sections may be altered without affecting basic compatibility. The following is a summary 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
19、requirements to permit great latitude of system configurations and the implementation of system features, only those 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 i
20、mplemented with either combined paging/access functions or as separate paging and access channels. i STD-EIA EIA/TIA-553-A-ENCL 1979 32311b00 Ob34254 21111 m each system is assigned a unique number.
