What is the full form of PCS and IVR?  

well
The IVR stand for Interactive Voice Response.
An automated telephone information system that speaks to the caller with a combination of fixed voice menus and data extracted from databases in real time. The caller responds by pressing digits on the telephone or speaking words or short phrases. Applications include bank-by-phone, flight-scheduling information and automated order entry and tracking.

Most IVR systems reside in PCs equipped with specialized PCI cards that connect to the telephone system to switch the calls. Systems can be networked on LANs and come with software that lets the developer create applications quickly. Most allow for the building of call flows by dragging and dropping icons of functions.

PCS stand for personal communications service.
pcs is a wireless phone service similar to cellular telephone service but emphasizing personal service and extended mobility. It's sometimes referred to as digital cellular (although cellular systems can also be digital). Like cellular, PCS is for mobile users and requires a number of antennas to blanket an area of coverage. As a user moves around, the user's phone signal is picked up by the nearest antenna and then forwarded to a base station that connects to the wired network. The phone itself is slightly smaller than a cellular phone.

PCS (personal communications service) is a wireless phone service similar to cellular telephone service but emphasizing personal service and extended mobility. It's sometimes referred to as digital cellular (although cellular systems can also be digital). Like cellular, PCS is for mobile users and requires a number of antennas to blanket an area of coverage. As a user moves around, the user's phone signal is picked up by the nearest antenna and then forwarded to a base station that connects to the wired network. The phone itself is slightly smaller than a cellular phone. According to Sprint, PCS is now available to 230 million people.

The "personal" in PCS distinguishes this service from cellular by emphasizing that, unlike cellular, which was designed for car phone use and coverage of highways and roads, PCS is designed for greater user mobility. It generally requires more cell transmitters for coverage, but has the advantage of fewer blind spots. Technically, cellular systems in the United States operate in the 824-849 megahertz (MHz) frequency bands; PCS operates in the1850-1990 MHz bands.

Several technologies are used for PCS in the United States, including Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Global System for Mobile (GSM) communication. GSM is more commonly used in Europe and elsewhere.

Interactive Voice Response (IVR) is an automated telephony system that interacts with callers, gathers information and routes calls to the appropriate recipient. An IVR system (IVRS) accepts a combination of voice telephone input and touch-tone keypad selection and provides appropriate responses in the form of voice, fax, callback, e-mail and perhaps other media.

An IVR system consists of telephony equipment, software applications, a database and a supporting infrastructure. Common IVR applications include:

* Bank and stock account balances and transfers
* Surveys and polls
* Office call routing
* Call center forwarding
* Simple order entry transactions
* Selective information lookup (movie schedules, etc.)

An IVR application provides pre-recorded voice responses for appropriate situations, keypad signal logic, access to relevant data and, potentially, the ability to record voice input for later handling. Using computer telephony integration (CTI), IVR applications can hand off a call to a human being who can view data related to the caller at a display.

Definition of: IVR

(Interactive Voice Response) An automated telephone information system that speaks to the caller with a combination of fixed voice menus and data extracted from databases in real time. The caller responds by pressing digits on the telephone or speaking words or short phrases. Applications include bank-by-phone, flight-scheduling information and automated order entry and tracking.

Handle the Easy Questions
IVR systems allow callers to get needed information 24 hours a day. They are also used as a front end to call centers in order to route as many calls as possible away from costly human agents. In such cases, IVR does not replace the agent, but keeps them from constantly having to answer the same simple questions.

The IVR System
Most IVR systems reside in PCs equipped with specialized PCI cards that connect to the telephone system to switch the calls. Systems can be networked on LANs and come with software that lets the developer create applications quickly. Most allow for the building of call flows by dragging and dropping icons of functions.

Abstract
Personal Communications Services (PCS) promise voice communication with both location and terminal independence. However, people today communicate using a variety of new means of information representation. Media other than voice, such as fax, e-mail, paging, video and multimedia have generally been classified as "advanced" or "enhanced" services. However, these technologies have matured sufficiently that many of them are in everyday use. This paper analyzes the types of interactions between an end-user and the network of the future. It presents a model of the type of functionality expected of a network to provide not only the location and terminal independence that PCS promises, but also a degree of information medium independence that the end-user of today requires
