Next, the transmission of system information capable of confirming the call coverage discounted area according to the present invention will be described in more detail.

2A to 2B are diagrams for explaining channels in a forward and a reverse link in a mobile communication system.

As shown in Fig. 2A, the channel on the forward link in the mobile communication system transmits a pilot channel, a synchronization channel, a paging channel, a call channel, and a power controller channel from the base station to the mobile communication terminal, as shown in Fig. 2B. Likewise, the channel on the reverse link in the mobile communication system transmits an access channel and a call channel from the mobile communication terminal to the base station.

Next, the forward CDMA channel formed from the base station to the mobile communication terminal will be described in detail.

In general, a forward CDMA channel, which is a CDMA channel transmitted from a base station (BTS) to a mobile communication terminal, is composed of one or more code channels transmitted on a CDMA assigned frequency using a predetermined pilot PN offset. It is divided into paging channel and call channel.

More specifically, the pilot channel is an unmodulated, direct sequence spread signal that each CDMA base station continuously transmits to the mobile communication terminal. The mobile communication terminal obtains the timing of the forward CDMA channel through this channel, A phase reference is obtained and the call strength between base stations is determined using the signal strength of this channel.

In general, each base station of a CDMA cellular system transmits a pilot carrier. The mobile terminal uses the pilot carrier to perform initial system synchronization to track and find out the correct time, frequency, and phase signals from the base station. The mobile terminal always tracks the pilot signal and adjusts the transmission output of the pilot signal to provide service. The size of the available area can be adjusted.

The sync channel is also used in the system acquisition phase as a forward channel, and once the mobile terminal has acquired the system, there is no need to reuse the sync channel until the power is turned on again. In this case, the content of the message sent by the sync channel is the message type (MSG_TYPE), protocol revision number (P_REV), minimum protocol revision number (MIN_P_REV), system identifier (SID) to identify the service provider, and network identifier to distinguish the exchange. (NID) and the like.

In addition, the paging channel is a code channel for transmitting synchronization control information and paging, and the mobile communication terminal searches for a paging channel after adjusting the time of the mobile terminal to the system time through a synchronization channel message. When a mobile communication terminal is waiting or starts a call for the first time, it monitors a paging channel and receives a control command from a base station to perform various functions such as access for initial call, short service, and hand off.

Also, a call channel is a communication path between a mobile communication terminal and a base station used to transmit subscriber traffic and signal traffic, and is used to transmit primary traffic, secondary traffic, and signal traffic from one mobile communication terminal to one or more base stations. A reverse call channel, which is a reverse CDMA channel, and a forward call channel, which is a code channel used for transmitting signal traffic from a base station to a mobile communication terminal.

As described above, the system information for confirming the region to which the call discount is applied according to the present invention is transmitted when the mobile communication terminal is located under the control of the base station that manages the region information set by the subscriber's selection. The above system information may be transmitted between the base station and the mobile communication terminal on the paging channel before the radio call is established.
