1、TIA STANDARD IS-41-C Enhancements for Circuit Mode Services TIA-737 JANUARY 2002 TELECOMMUNICATIONS INDUSTRY ASSOCIATION The Teleconmiunications Industry Association represents the conmiunications sector of NOTICE TIAIEIA Engineering Standards and Publications are designed to serve the public intere
2、st through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publicatio
3、ns shall not in any respect preclude any member or nonmember of TIAIEIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIAIEIA members, whether the s
4、tandard is to be used either domestically or internationally. Standards and Publications are adopted by TIAIEIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIAIEIA does not assume any liability to any patent owner, nor does it assume any obligat
5、ion whatever to parties adopting the Standard or Publication. TIA STANDARDS TIA Standards contain information deemed to be of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comm
6、ents which is a procedural part of the development of a TIAIEIA Standard. TIA Standards should be reviewed on an annual basis by the formulating Committee and a decision made on whether to proceed to develop a TIAIEIA Standard on this subject. TIA Standards must be cancelled by the Committee and rem
7、oved from the TIAIEIA Standards Catalog before the end of their third year of existence. Publication of this TIA Standard for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIA Standard for comment shall not continue beyond 60 months from
8、 the date of publication. It is expected that following this 36 month period, this TIA 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 & Technology

26、0 1 .I Asynchronous Data Service (ADS) This telecommunication service allows digital wireless subscribers to send and receive asynchronous data. ADS provides functionality similar to a wireline modem in that the data is modified to malte it suitable for transporting over the appropriate medium. Both
27、 wireless and wireline media are accommodated to support inteiworlung between the two networks in a way that is transparent to the terminal equipment. The subscribers terminal equipment inteifaces to a conventional DCE (Data Circuit-Teiminating Equipement) data port. The far-end DCE inteiworlts each
28、 end function as if connected to a compatible device. ADS procedures and inteifaces are specified by appropriate air interface standards (e.g., TIA/EIA/IS-99 orTIA/EIA/IS-I 35 and TIA/EIA/S-I 30). These TIA standards specify compliance with other common TIA data standards (e.g., EIA/TIA-602) and ITU
29、 recommendations (e.g., . V32 bis, V.42). Mobile originated service may be of two types: Data Only and Voice Then Data. Mobile terminated service may be of three types: One Number per Service, Two-Stage Dialing, or Voice Then Data. Applicability to Telecommunications Services ADS is applicable to da
30、ta telecommunication services. ADS is applicable to voice services in those cases where a voice call is made prior to a user initiated voice to data service change. 1 .I .I Normal Procedures With Successful Outcome Authorization ADS may be provided after preail-angement with the service provider, or
31、 may be made generally available by the service provider. De-Au t h 0 rizat 1 0 n If ADS is provided after preail-angement with the service provider, the sei-vice shall be deauthorized at the subscribers request or for administrative reasons. Reg ist ration ADS has no registration. De-Reg ist rat 1
32、on ADS has no deregistration. Stage 1 - 1 Asynchronous Data Service (ADS) TIA-737 Activation ADS shall be activated upon authorization and issuance of the proper AT command. De-Activation ADS shall be de-activated upon deauthorization or issuance of the proper AT command. Invocation ADS is invoked b
33、y issuing the appropriate AT commands (e.g., ATD command). Mobile Origination Mobile originated service may be of two types: Data Only and Voice Then Data. - Data Only A mobile subscriber originates a data call to a terminating party (PSTN user or mobile subscriber). The terminating party may either
34、 have a separate telephone number for data services, or (based on calling tones, alerting pattein, or some other means) utilize a single line to terminate both voice and data services. - Voice Then Data A mobile subscriber originates a voice call to a terminating party (PSTN user or mobile subscribe
35、r). The terminating party has a single telephone number for both voice and data services. The call is answered as a voice call when the modem is made ready, the mobile subscriber initiates a voice to data service change. In another case, the originating mobile subscriber infoi-ms the terminating par
36、ty that the inprogress voice call shall be ended, then call back with a data call. The originating mobile subscriber then initiates a data call. Mobile Termination Mobile terminated service may be one of three types: One Number per Service, Two- Stage Dialing, or Voice Then Data. - One Number per Se
37、rvice An originating party places a data call to the terminating mobile subscriber. The mobile station has a separate telephone number for data calls. - Two-Stage Dialing The wireless carrier has one or more Directory Numbers (DN) for ADS service. Since the number is related to the service, it is sh
38、ared by all subscribers. An originating party places a call to one of the ADS DNs. The number selected corresponds to the requested data service. When the data service retuns dial tone, the originating partys modem dials the terminating mobile subscribers DN. The call is presented as a data call. 1

The subscribers mobile termination has a single telephone number for both voice and data services. The mobile subsc
41、riber answers the call using voice service and initiates a voice to data sei-vice change. In another case, the originating party infoi-ms the tei-minating mobile subscriber that he or she shall end the current voice call, then call back with a data call. The mobile subscriber manually switches the s
42、ervice fom voice to data service prior to receiving the call. Call Detail Record The system should record call detail information for the following: a. Sei-vice invocation event and time. b. Elapsed time for Voice and ADS. c. Use of the InterWorlting Function (IWF). d. Number of Octets (or Packets).

44、he end-to-end call, or if the in progress call is interrupted, the network may clear the call. The originator of the call should be provided an indication that the call has failed.
