Call service method using base station without RFC power output in PCS system {CALL SERVICE METHOD USING THE BTS WITHOUT RF POWER IN PCS SYSTEM}

The present invention relates to a call service method using a base station without an RF power output in a PCS system, and more particularly, an error occurs in a control station or communication line to which a normal base station belongs during a call service using a base station without an RF power output. The present invention relates to a call service method using a base station having no RF power output in a PCS system that receives a call service from a neighboring base station by blocking pilots and sinks output from the base station when the call service is not performed.

Referring to a call service method using a base station in a conventional PCS system, a general terminal is a base station that transmits the strongest pilot and sink after receiving control data carrying pilots and sinks from a plurality of base stations. Called for call service. Then, when the base station that has received a call service from the terminal has an error in the control station or an error in the communication line, HPA (High Power Amplifier; hereinafter called HPA) in the base station RF unit, LPA ( By blocking the output portion of the linear power amplifier (hereinafter referred to as LPA), a method of receiving a pilot and a sink from a neighbor base station and requesting a call service was used.

However, some of the base stations hypothesized in the subway, there was a base station to output the pilot and the sink of the base station by using an optical repeater, such as not using the output portion such as the LPA, HPA. In the call service method using the base station, since there is no device that can block the power output portion that outputs the pilot data transmitted from the base station and the control data loaded with the sink, the terminal receives the pilot service and the sink from the base station. Even if required, the call service is not made, and as a result, a call incapacity condition occurs because the call service cannot be derived from the neighboring base stations, and thus, there is a problem in that a smooth call service is not provided to many users.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to block a pilot and a sink output from a base station when an error occurs in a control station or a communication line, thereby providing a call service from an adjacent base station. The present invention provides a call service method using a base station having no RF power output in a PCS system to provide a higher quality mobile communication service to users.

In order to achieve the above object, a call service method using a base station without an RF power output in a PCS system of the present invention includes a control station having a CCP for outputting a traffic channel allocation command when a call is attempted or a handoff is performed; A base station having a BCP for allocating one channel element to connect a call when receiving a traffic channel allocation command from the CCP in the control station, and a channel card including a plurality of channel elements for performing a modulation / demodulation function for one call. ; A call service method using a call service apparatus using a base station without an RF power output in a PCS system configured to receive a control data from the base station and request a call service.

Hereinafter, a call service method using a base station without a radio frequency (RF) power output in a personal communication service (PCS) system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram of a call service apparatus using a base station without an RF power output in a PCS system according to an embodiment of the present invention, the base station without an RF power output in a PCS system according to an embodiment of the present invention Call service apparatus using a control station 100 having a Call Control Processor (CCP) (110); A base station 200 having a BCP (BS Control Processor; BCP) 210, and a channel card 220; And a terminal 300.

The CCP 110 mounted in the control station 100 is a processor that performs call processing control functions such as call setup and call release, handoff processing functions related to soft and hard handoff, and system maintenance functions. When a call is attempted or a handoff proceeds, a traffic channel assignment command is output to the BCP 210 in the base station 200, and the base station 200 is controlled.

On the other hand, the BCP 210 mounted in the base station 200 controls and manages the sub-devices mounted in the base station 200, provides a smooth interface between the control station 100 and the sub-devices, A processor that performs call processing, shape information management, statistics and measurement, and error / error processing, which are inherent to the system, are stored in an internal memory, and a voice traffic channel allocation threshold and a data traffic channel allocation threshold are stored in the internal memory. It receives a traffic channel allocation command from the CCP 110 in the control station 100 and allocates one channel element to connect a call, while periodically communicating with the CCP 110 in the control station 100. After checking the state of the control station 100 to transmit the block command control signal and the output command control signal to the channel card 220 in the base station 200, And it serves to transmit to the group controller 100 is a communication line control block command signal and the output command control signal, the local base 200 within the channel card 220 to also check the status of the connection with.

In addition, the channel card 220 mounted in the base station 200 is a processor that is composed of a plurality of channel elements to perform modulation / demodulation functions for one call when performing call processing, respectively, the BCP in the base station 200. When the block command control signal is input from the control unit 210, the control data loaded with the pilot and the sink is blocked from being output to the terminal 300, while the output command control signal is received from the BCP 210 in the base station 200. It serves to output the control data carrying the pilot and sink to the terminal 300 through an optical repeater (not shown).

On the other hand, the terminal 300 receives the control data loaded with the pilot and the sink from the base station 200 requests the call service to the base station 200 and serves to provide a mobile communication service to the user.

Then, a call service method using a base station without an RF power output in a PCS system according to an embodiment of the present invention using a call service device using a base station without an RF power output in a PCS system having the above configuration Let's explain.

3 is a flowchart illustrating a call service method using a base station without an RF power output in a PCS system according to an embodiment of the present invention.

First, the BCP 210 mounted in the base station 200 periodically communicates with the CCP 110 mounted in the control station 100 to receive and report that there is no response or abnormal state from the control station 100. The state of the control station 100 is checked (S1).

Thereafter, the BCP 210 determines whether an error has occurred in the control station 100 (S2).

At this time, if an error occurs in the control station 100 in the second step S2, the process proceeds to the fifth step S5, while an error occurs in the control station 100 in the second step S2. Otherwise, the BCP 210 periodically checks the state of the hardware chip of the communication line E1 / T1 connected to the control station 100 (S3).

Thereafter, the BCP 210 determines whether an error has occurred in the communication line E1 / T1 (S4).

At this time, if an error occurs in the control station 100 or the communication line in the second step (S2) or the fourth step (S4), the BCP 210 sends a block command control signal for blocking the pilot and sink. The base station 200 transmits to the channel card 220 (S5).

Then, the channel card 220 mounted in the base station 200 receives the block command control signal from the BCP 210 and blocks the pilot and the sink from being transmitted to the terminal 300 (S6). ).

On the other hand, if the error does not occur in the communication line in the fourth step (S4), the BCP 210 mounted in the base station 200 outputs an output command control signal for outputting the pilot and sink normally to the base station 200 In step S7, the channel card 220 is mounted within the channel card 220.

Then, the channel card 220 mounted in the base station 200 receives an output command control signal from the BCP 210 and at the same time performs a normal pilot and sink transmission operation to transmit it to the terminal 300 ( S8).

Referring to the above operation in more detail, as shown in Figure 2, when the terminal is located in region A and subscribed to the service provider A receives a call service from the base station A (200).

In this case, when an error occurs in the communication line between the base station A 200 and the control station A 100, the base station A 200 blocks the control data loaded with the pilot and the sink from being transmitted to the terminal.

Thereafter, the terminal requests a call service to an adjacent base station B 200 that receives a pilot and a sink, or requests a call service of a base station a 200 provided by a B service provider that is subscribed to receive a roaming service. As a result, a smooth call service is received from an adjacent base station 200.

In addition, as shown in Figure 2, when the terminal is located in the area B and subscribed to the service provider A receives the call service from the base station B (200).

In this case, when an error occurs in the communication line between the base station B 200 and the control station A 100, the base station B 200 blocks the control data loaded with the pilot and the sink.

Thereafter, the terminal receives a call service from an adjacent base station A 200 by requesting a call service to an adjacent base station A 200 in which a pilot and a sink are received.

On the other hand, if the terminal is located in the C region and is subscribed to the service provider A and roaming service, the terminal in the C region receives a call service from the base station C (200).

In this case, when an error occurs in the communication line between the base station C 200 and the control station B 100 or the control station B 100, the base station C 200 prevents the control data carrying pilot and sink from being transmitted to the terminal. Block it.

Thereafter, the terminal requests a call service to an adjacent base station B 200 that receives a pilot and a sink, or requests a call service of a base station b 200 provided by a B service provider that is subscribed to receive a roaming service. Thus, smooth call service is received from an adjacent base station.

Accordingly, when an error occurs in the control station or the call line to which the normal base station belongs, as described above, the output of the pilot and the sink is blocked from the base station, so that the call service can be smoothly received from the adjacent base stations.

As described above, according to the call service method using the base station without the RF power output in the PCS system according to the present invention, when a call service using the base station without the RF power output portion, an error occurs in the control station or communication line to which the normal base station belongs. When the call service does not occur because it occurs, by blocking the pilot and sink output from the base station to receive the call service from the neighboring base station by eliminating the call disabled state of the terminal to ensure that the call service is always made, This has an excellent effect of providing users with higher quality mobile communication services.
