3. 3 Status of S.P0125 (2 of 2)

4. 4 Service Definition Abbreviated Dialing: User dials a local-only legacy short code; The serving switch translates the short code to a ten-digit directory number on a global basis and routes the call. –Example: Dial *Pizza to reach a local Pizza place. Short Code Dialing: User dials a short code such as #BAL, #PAY, #PMT, #MIN. The serving switch translates the short code to a ten-digit directory number on a global basis and routes the call. # codes may be implemented locally only or globally throughout the operator’s Network. Vanity Number: User can call a NANP Directory Number that is greater than 10 digits in length. For example, the number 1-800-SEE-AMERICA equates to 1-800-733-2637422. Special switch translations are required to complete calls to vanity Numbers such as this. –Example: Making a call to 1-800-SEE-AMERICA when in San Diego, the call will be dispatched to tourist center in San Diego.

5. 5 Summary and Recommendation The main characteristics of the three services: –The number dialed is a non-E.164 number –Translation function is needed to map the short-hand/mnemonic number to the final destination address –The mapping may or may not be in the context of the caller’s location information Recommended Stage 1 Approach: –Create a unified requirement document for all three services instead of three separate requirement documents –Refer to the services under all three commonly used names put together: AD/SC/VN
