According to an aspect of the present invention, there is provided a method for controlling a service area in a wireless subscriber network system, the method comprising: establishing a call and storing information on a serviceable area received through a forward traffic channel of a set call in a memory; ; After releasing the call, checking the power state of the terminal; A third step of receiving a plurality of pseudo noise (PN) signals and selecting a PN having an optimal reception sensitivity among the received PNs when the power is turned on according to the confirmation result of the second step; A fourth step of analyzing whether the selected PN is a PN in a service area; And a fifth step of entering a service mode when the selected PN is a PN in a service area according to the analysis result of the fourth step. According to the analysis result, when the selected PN is not a PN in the service area, a sixth step of selecting a PN having the next highest reception sensitivity except the selected PN among the received PNs and proceeding to the fourth step The present invention stores in advance a serviceable area information (serviceable PN database) in the terminal, and allows the terminal to determine whether the service itself. These operations require initial entry or update as necessary, and these operations can be performed remotely. Code Division Multiple Access (CDMA) is used to remotely change information about the serviceable area inside the terminal. In the WLL system using the method, the Burst message of the forward forward channel message is used to transmit information (PN database) about the serviceable area to the terminal, and the terminal relates to the serviceable area according to a predetermined algorithm. Change the information (PN database) on its own. The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a call processing procedure in a wireless subscriber network system according to the present invention.

In Fig. 1, reference numeral 10 denotes a terminal, and reference numeral 20 denotes a base station.

First, when the base station 20 requests the call setup from the base station 20, the terminal 10 searches for the strongest PN signal among the numerous PNs to enter the service mode, and then moves to the channel having the largest strength of the PN signal. The call is set up, and when the call setup is completed, the call setup completion message is transmitted to the base station 20.

The base station 20 receives this information and transmits the information on the serviceable area to the terminal 10 by using the burst message among the forward traffic channel messages, and the terminal 10 uses the information on the serviceable area to be delivered. Update the information about the available area (PN database). When the update of the information on the serviceable area (PN database) is completed, the base station 20 transmits a message indicating that the update of the information on the serviceable area (PN database) is completed, and the base station 20 that has received the update ) Will release the established call.

In this case, when the base station 20 transmits the information on the serviceable area to the terminal 10, the information on the serviceable area is transmitted to the terminal 10 by defining "burst_type = 0000 1111" in the burst message. Inform.
