2、nic industris INDUSlRY AssoCIAl“0N Electronic Industries Altiancc NOTICE TWIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and
3、assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of MIA from manufacturing or selling products not conforming to such Standards and
4、Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than MIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIA/EIA in accordance with the American National
5、 Standards Institute (ANSI) patent policy. By such action, TIA/EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. TIA/EIA INTERIM STANDARDS TIA/EIA Interim Standards contain information deemed to be of te
6、chnical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a TIA/EIA Standard. TIA/EIA Interim Standards should be reviewed on an ann
7、ual basis by the formulating Committee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. MIA Interim Standards must be cancelled by the Committee and removed from the TMIA Standards Catalog before the end of their third year of existence. Publication of this MI
8、A Interim Standard for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TI.AEI.4 Interim Standard for comment shall not continue beyond 36 months from the date of publication. It is expected that following this 36 month period, this TIMEIA
9、Interim Standard, revised as necessary, will be submitted to the American National Standards Institute for approval as an American National Standard. Suggestions for revision should be directed to: Standards and a mobile supporting wireless residential service is compatible with a Personal Base (PB)
10、 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-system parameters and call-processing proce
11、dures 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 that cellular systems are based upon. The sequence of call processing steps that the mobile stations and base
12、 stations execute to establish caiis has been specified dong 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. Radiated power levels, both desired and undesired, a
13、re 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 that the station operates in. Detailed call-processing procedures are
14、 specified for mobile stations to ensure a uniform response to ail 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 land system. This approach to writing the compatibility specification provide
15、s the land 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 specification were originally derived from the Chica
16、go and Baltimore-Washington developmental cellular systems and include certain additions and modifications gained by experience with the operation of commercial systems. As comercial systems evolve there may be a need for additional capabilities primarily in the area of call- processing procedures a
17、nd new system features. It is important that evolutionary changes be readily accommodated. To that end, these technical requirements have been organized into eight general sections. Alterations to 2 and 3 can affect fundamental public cellular mobile station - base station compatibility. All other s
18、ections 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 requirements to permit great lat
19、itude of system configurations and the implementation of system features, only those items required for compatibility have strict definitons. Other items may be interpreted to fit the needs of manufacturers and system operators. For example, control channels may be implemented with either combined p
20、aging/access functions or as separate paging and access channels. 2. Mobile Station Compatibility Requirements. This section comprises the fundamental signaling compatibility requirements of mobile stations (MSs). If strictly adhered to, a mobile station technically will be able to signai a base sta
21、tion. This section assures communications only if service is not otherwise restricted by operational or RF signal level constraints. For example, service may be denied for reasons of subscriber credit or because the mobile station is out of the effective range of a base station. In general, changes
22、or alterations to this section will affect fundamental mobile station - base station compatibility and the ability of mobile stations to signal base stations irrespective of operational or RF signal level conditions. 1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 TIA/EIA/I
23、S-9 1 -A 3. Base station Compatibility Requirements. This section comprises the fundamental signaling compatibility requirements of base stations(BSs) and is organized in a manner similar to 2. (In fact, 2 and 3 should be read together for a clearer understanding of the bi-directional signaling prot
24、ocol.) If strictly adhered to, a base station technically will be able to signal a mobile station. As in 2, communications are assured only if not otherwise restricted by factors such as FtF signal limitations or operational limitations. In general, changes or alterations to this section will affect
25、 fundamental mobile station - base station compatibility and the ability of mobile stations to signal base stations irrespective of operational or RF signal level conditions. 4. Mobile Station Options. This section is reserved for requirements for use of optional functions and features by mobile sta
26、tions 5. Base station Options. This section is reserved for requirements for use of optional functions and features by base stations. 6. This section comprises the fundamental signaling compatibility requirements of mobile stations operating in the wireless residential extension (WRE) mode. If stric
27、tly adhered to, a mobile station technically will be able to signal a personal base. This section sets forth ail of the mobile station requirements to implement a WRE that avoids interference with macro cellular systems. Mobile Station Wireless Residential Extension Requirements. 7. Personal Base Re
28、quirements. This section comprises the fundamental signaling compatibility requirements of a personal base (PB). If strictly adhered to, a personal base will be able to inter-operate with a mobile station in WRE mode. This section sets forth all of the personal base requirements to implement a WRE t
29、hat, with suitable management by the system operator, avoids interference with macro cellular systems. It should be read in conjunction with section 6. 8. Change History. This section traces all changes to these technical requirements beginning with the initial release of this standard. A brief desc
30、ription of each change as well as a reference to the affected section(s) is provided. 11 STD=EIA TIA/EIA/IS-SL-A-ENGL 1999 3234b00 Ob34842 TL8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 1. la. lb. 3. 4. 5. 5a. 6. 6a. 7. 8.

31、/EIA/IS-91-A NOTES Compatibility, as used in connection with these standards, is understood to mean: Any mobile is able to place and receive calls in any cellular system. Conversely all systems are able to place and receive calls for any mobile station. In a subscribers home system, ail call placeme
32、nt shall be automatic. it is preferable that cai1 placement be automatic when a mobile station is in roam status. Compatibility in CAPCS, as used in connection with these standards, is understood to mean: Any mobile station supporting the optional CAPCS capability is able to place and receive calls
33、in any CAPCS system if so authorized. Conversely, all systems are able to place and receive calls for any mobile station if so authorized. Compatibility in WRE, as used in connection with these standards, is understood to mean: Any mobile station supporting the optional WRE capability is able to pla
34、ce and receive calls with any personal base if so authorized. Conversely, all systems are able to place and receive calls for any mobile station if so authorized.2. The term “mobile station“ is defined as one I. intended to be used while in motion or during halts at unspecified points.“ It is assume
35、d that mobile stations include portable units (e.g., hand-held personal units) as well as units installed in vehicles. This compatibility specification is based upon the specific US spectrum allocation for cellular systems. Technical details are included for the operation of two systems in a geograp
36、hic area, System A and System B, each with a separate set of control channels. ANSI TIA/EIA 690, Recommended Minimum Standards for 800MHz Celluhr Subscriber Units, and ANSI TIAIEIA 712, Recommended Minimum Standards for 800 MHz Cellular Base Stations“ provide specifications and measurement methods f
37、or cellular equipment. EIA IS-90 and EIA IS-89, respectively, provide the equivalent for narrow analog equipment. TIAiEIA-690, as amended per Annex C of this document, defines the recommended minium performance standards for CAPCS mobile stations. ANSI/TIA/EIA-712, as amended per Annex D of this doc
38、ument, defines the recommended minium performance standards for CAPCS base stations. Each cellular system is identified by a unique 15-bit digital code, the SID code (see 2.3.8). The Federal Communications Commission assigns SID codes when cellular system construction permits are issued. Each auxili
39、ary cellular system is identified by a unique 15-bit digital code, the ASID (see 2.3.8). Each cellular carrier will maintain and coordinate the CAPCS ASID codes for systems in its licensed coverage area. Each mobile station is assigned a unique 32-bit binary serial number that cannot be changed by t
40、he subscriber without rendering the mobile station inoperative (see 2.3 -2). In the message formats used between the mobile stations and base stations, some bits are marked as reserved (RSVD). Some or all of these reserved bits may be used in the funire for additional messages. Therefore, ail mobile
41、 stations and base stations shall set all bits that they are programmed to treat as reserved bits to O (zero) in all messages that they transmit. All mobile stations and base stations shall ignore the state of all bits that they are programmed to treat as reserved bits in ail messages that they rece

In cellular the following enhancement
43、s were added: Support for Class IV mobile stations; a method of dividing the control channel that allows capable mobile stations to “ sleep“ during defined periods (idle sleep mode), thereby improving battery life in the mobile station; an optional system planning tool that aliows the cellular syste
44、m to query capable mobile stations for the signai strength of specified channels (downlink measurement protocol); a means for designating and operating on preferred access channels; a means for providing autonomous registration based on location; and a means for providing autonomous registration bas
45、ed on power up and power down. For the CAPCS mode of operation the IS-94 standard was merged with the corresponding sections of IS-91. In addition to adding the sleep mode and downlink measurement protocol described above, NAMPS operation and a simplified authentication method was also provided. An
46、entirely new service was added in sections 6 & 7 that will allow “personal bases“ to operate in the cellular spectrum on 10 kHz channels without interfering with the macro cellular system. These personal bases will aiiow mobile stations to operate in a manner similar to cordless telephones and will
47、provide automatic call forwarding of the cellular number. The standard has been designed to provide a common air interface between the personal base and mobile station, thus permitting interoperability between different manufacturers equipment. Associated with this new service is a separate interim
48、standard (IS-680) that describes the interface between the personal base and the cellular system, thus providing a common interface between different manufacturers personal bases and the cellular system. There are four normative annexes in this Standard. Annex A covers message encryption and Annex B
49、 is the allowable character set. Annex C describes changes to EIA/TIA-690 and TiA/EIA/IS-90 to accommodate CAPCS mode of operation. Annex D describes changes to ANSI/TIA/EIA-712 and TIA/EIA/IS-89 to accommodate CAPCS mode of operation. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 - STDDEIA TIA/EIA/IS-SL-A-ENGL 1997 323Lib00 Ob348b0 T33 H TIA/EIA/IS-9 1-A 1 INTRODUCTION 1.1 scope These technical requirements form a compatibility standard for a cellular radio telecommunications system.
