The IN protocols and concepts can be used to implement enhanced wireless services rapidly and to have these services available across serving areas in an untethered wireless network. Some of these services are listed below:

Voice-Based User Identification. This service employs a form of automatic speech recognition to validate the identity of the speaker. Access to services can then be restricted to the user whose voice (phrase) has been used to train the recognition device.

Voice-Based Feature Control. This service allows the authorized user to specify feature operations, which can be carried out via featurecontrol strings by means of spoken commands.

Voice-Control Dialing. This service allows the subscriber to place a call using spoken commands.

Voice-Controlled Services. This feature allows the subscriber to control features and services using spoken commands.

Incoming Call-Restriction/Control. This service allows users to impose restrictions to an incoming call as follows: it may terminate normally to the subscriber; it may terminate to the subscriber with normal alerting; it may terminate to the subscriber with special alerting; it may be forwarded to another number; it may be forwarded to voice mail; it may be routed to any specific announcement; or it may be blocked.

Calling Name Presentation. This service provides the name identification of the calling party (personal name, company name, restricted, not available) as well as the date and the time of the call.

Password Call Acceptance. This service allows the subscriber to restrict incoming calls only to those callers who can provide valid passwords.

Selective Call Acceptance. This service allows the subscriber to restrict incoming calls only to those calling parties whose numbers are in the restricted list.

Short Message Service. This service allows the short message entities (SMEs)—the short message users—to receive or send short messages (packet of data).

Speech-to-Text Conversion. This service allows the user to create a short alphanumeric message by means of spoken phrases.

Prepaid Phone. This service allows the user to pay before calling, i.e., not to be billed (postpaid). This can take a number of forms, for example, a debit card, a connection to a smart card, and others.
