URI Fields (SMS)

Origination Date :06/09/2008

Originator:LNPA-WG

Description:

Business Need:

SMS (texting) is a store and forward messaging service that allows SMS-compatible subscribers to send and receive short text messages.  SMS subscribers are addressed via their 10-digit telephone number and an e-mail address.  SMS is transported via IP by the originating network using URIs to indicate the network address or gateway SMSC of the terminating user.  SMS is growing into a broadband wireline feature as a result of the growth of IP-based broadband networks.

SMS originating Carriers need to know if a terminating 10 digit TN is SMS capable (wireless or broadband) and if SMS capable the address of the SMSC.  Having a standardized central source to locate the TN/SMS mapping will eliminate attempts to deliver messages to non-SMS capable TNs and reduce customer complaints over dropped or missed messages that have not, nor could be delivered.  The NPAC SMS URI parameter function would be analogous to the DPC/SSN gateway data in the NPAC; that is, the “URI” would merely identify the carrier gateway (SMSC) appropriate for sending/receiving an SMS message to a particular ported or pooled TN.

The availability of the SMS URI will allow originating carriers to recognize SMS capable TNs so that IP based carriers delivering service to traditionally “landline” numbers from wireless TNs can determine if the TN is SMS capable and use the URI for terminating network routing information.  Increased usage and a high success rate on message delivery are the two primary benefits of this new NPAC feature.

Final Resolution:

Func Backward Compatible:  Yes

Jun ’08 LNPAWG, discussion:

After walking through the Business Need section, and a brief explanation of the Description of Change, the group agreed to accept this change order, and allow it to be prioritized along with the change orders for the next package.

May ’09, SOW 72 was approved by the NAPM, and will be implemented during the Jun/Jul ’09 timeframe.

This change order adds a new field (SMS URI) to the subscription version and number pool block objects.
