Item Description
Short Message
Service (SMS)
SMS delivers short messages of up to 140 characters to an MS.
This requires the Short Message Service Center (SMS-SC) and
software to the MSC to interface and interwork with the SMS-SC.
The SMS stores and forwards messages to MSs. If the messages
cannot be delivered, the SMS-SC stores them for future delivery.
Voice Mail
Interface
Voice Mail allows otherwise interminable calls to be routed to a
Voice Mail system. Voice Mail Messages are recoverable from
either an MS or a Landline telephone. Two interfaces provide
connectivity between the MSC and the Voice Mail system.
Regular voice trunks provide the audio connection.
Selection and setup of the voice trunk route that the redirected call
will use is performed by the SS7.
This interface conforms with ANSI SS7 ISUP in accordance with
the Bellcore TR-NWT-000317 specification.
Data Services System Data Services uses IWF to support:
• Group 3 FAX
• asynchronous data
The MSC contains call control and routing functions for data and
FAX services
Non-Transparent Async Data and Non-Transparent FAX are not
supported
IWF requires the purchase of IWF hardware and software. The
MSC software to support IWF functionality must be purchased as
part of the IWF Hardware package.
Information
Services
Mobile originated, 10-digit, 900 number calls (900+NXX+XXXX)
will be translated and routed to the PSTN like any other 10-digit
number. No special translation handling is needed. Also, no special
treatment is needed. Air time and 900 Service Charges are applied
like any other call.
Routing to PSTN
Operator
The iDEN system will route various type calls to a trunk
terminating to a PSTN operator (0+ and 0- calls) through standard
translations. The MSC does not support operators (Does not have
Mobile Operator Position System (MOPS) capability.)
Emergency Call
Enhancements
The iDEN system assures that the Location Area Code (LAC) and
cell identification are used to properly route an emergency call to
the nearest service center
MSID for
Emergency Calls
Allows the operator to trace prank Emergency Callers by providing
the capability for the GCDR records to identify the caller using the
mobile station ID. This applies to an MS making Type I
Emergency calls. It allows billing records generated by Emergency
Calls may be routed to the HOT Billing Stream (if available) or the
GSM Call Detail Record (GCDR) stream.
E-911 Phase One
Enhancements
The iDEN system provides compliance with Phase I of the FCC’s
requirement for E911 calls by introducing support for transmission
of an emergency callers callback number and location (by cell site)
to a Public Safety Assistance Provider (PSAP).
