KR100259865B1 - Method for distinguishing and serving the incoming call signal in ct2 base station - Google Patents

Abstract

PURPOSE: A method for discriminating incoming calls and providing termination service in a CT2 base station is provided to discriminate incoming calls by discriminating and accepting destination ring signals from a base station according to an operation appointed state of a PSTN line. CONSTITUTION: If a ring is detected from a PSTN line in the state that a base station is in a call processing mode, the base station inquires into an operation appointed state of the appointed line. If the operation appointed state of the appointed line is a line set up so as to service a destination path, the base station carries out DTMF analysis to detect an extended number and searches whether there exists an arbitrary terminal PID(Portable ID) in a destination registration list for incoming call processing. If a related PID exists, the base station starts polling to trace the location of a terminal within a relevant cell. After polling the terminal, the base station sends a termination ring to the terminal in the cell if a response is received from the terminal.

Description

Incoming call determination method and incoming call method of Citi 2 base station

The present invention relates to a method of determining an incoming call and an incoming service method of a CT2 base station. In particular, a method of configuring a modem communication signal and an incoming call and data of a base station and a management device using a modem are provided. The present invention relates to a method for setting base station configuration information for serving an incoming call without exchanging control data in a system having a configuration of exchanging c).

Looking at the prior art as follows. In Canada, the CT2 system uses a dedicated frequency band for polling as a B channel or an incoming service for communication, which requires a separate frequency resource for the pilot.

In addition, in the case of the Taiwan CT2 using the French Dassault system, the subscriber's incoming location is transmitted by the base station by the user's artificial registration operation or the user's prior programming. Therefore, when the subscriber changes the called location, it is impossible to receive a call without re-registration by the subscriber, and thus, it is impossible to provide a complete call. Even in the case of the domestic adopting the scheme, the base station is connected to the base station controller by a dedicated line. Indirect call service using manual location registration similar to the Taiwan case is provided.

As described above, the base station and the base station control apparatus are conventionally connected by a dedicated line, and for the incoming service, polling must be periodically performed in a network connected to the base station, the control apparatus, and the exchange. On the other hand, the extension number incoming service provides the function for incoming calls when the base station is directly connected to the public switched telephone network (PSTN), which reduces additional equipment for incoming calls and saves the line and time used for terminal location tracking. It also has the advantage of being able to.

However, the prior art as described above provides a call receiving function using a subscriber registration and deletion function, where a subscriber inquiry is performed by a home location register (HLR) system or a visitor location register (VLR) connected to an exchange. While searching the system, the extended number incoming service has a function of registering, inquiring, and deleting variable subscribers by a special key. The extended number incoming service can reduce unnecessary polling because the subscriber list per base station call is first retrieved when receiving the call. However, according to the related art, a base station controller and a base station, which are sub-systems, search for a home subscriber registration system or a visitor location registration system in a network. Because of the interworking, the complexity of network operation and the cost of configuration are expensive.

In addition, the incoming call to the base station uses a PSTN line only for the transmission of various configuration information elements, and the base station using the modem receives a call and a call for maintenance from the management device to the base station. The base station polls the terminal periodically for the incoming call and repeatedly uploads the data to the upper system for each incoming call. There is a problem that it is consumed for tracking.

The present invention was made to solve the problems of the prior art as described above, by receiving the incoming ring signal received by the base station by distinguishing according to the operation designation state of the PSTN line to distinguish the incoming signal, and to the public base station An object of the present invention is to enable an incoming service to a terminal having a registered PID (Portable ID: Terminal Identification Number) from a designated base station by using a PID list to grant a private terminating function to a base station to be used according to ownership.
