Hereinafter, the objects and features of the present invention will be described in more detail with reference to the accompanying drawings so that the objects and features of the present invention can be more clearly understood.

FIG. 1 is a block diagram of a method for displaying charging information in a personal communication switching network according to the present invention. The base station transceiver system (hereinafter, abbreviated as BTS) unit 10 and base station control (Base Station Control) It is composed of a BSC unit 20, a PCX 30, a call signal processor 32, a charge calculator 34, and a short message processor 36.

The BTS unit 10 has wireless signal transmission and reception, system synchronization, wireless channel encoding and decoding signal strength and quality measurement, baseband signal processing, diversity, radio resource management and self-maintenance functions, and wirelessly matches with a corresponding subscriber. It is a base station transmission and reception system under the control of the BSC unit 20.

The BSC unit 20 is a block that performs functions such as matching, inter-cell handoff processing, call control, etc. with the BTS unit 10. The BSC unit 20 is connected to the PCX 30 through an internal interface of the switch or a NO.7 link. 20 controls a plurality of BTS units 10.

The PCX 30 provides an exchange function between personal communication subscribers and has an information exchange function by interfacing with an unshown HLR that provides subscriber information to perform an exchange function according to a subscriber's call request.

In addition, PCX 30 is a personal communication switch for transmitting and receiving signals and voice data with the MS, and an outgoing signal processor 32 for processing a call originated from the MS internally, and called party number, called location information, call start information, and the like. Using the rate calculation unit 34 to calculate the rate information of a few seconds from the included rate information calculation element and transfer it to the call signal processing function, and short message service (hereinafter, abbreviated as SMS) function It is provided with a short message processing unit 36 for transmitting the charge information to the MS, which is the calling terminal, and the MS, which is the calling terminal, displays the fee information on the display of the terminal to inform the user of the fee.
