Abstract

PURPOSE: A method for processing a directly terminated call in an originating-dedicated CT-2 is provided, in CT-2 directly terminating system, to offer a direct terminating service to a subscriber by managing the location data of the user. CONSTITUTION: In an originating-dedicated CT-2 for processing a signal terminated among the originating CT-2 terminal(MS), CT-2 base station(BS), CT-2 base station controller(BSC), CT-2 exchange(CTX) and CT-2 subscriber data manager(CTH), if the CT-2 exchange recognizes the call is terminated to CT-2 terminal, it performs an originating signal process and makes inquiries about the location data of the terminal to CTH. Then, CTX requests a terminal paging to the received location data. If the terminal receiving the terminal paging responds to the base station, the base station responds to BSC, then the BSC to CTX. The CTX receiving the paging response performs a terminating signal process and performs a terminating signal setting with the MS in order to connect a wireless/wired channel between the terminal terminated and the CTX. The originating subscriber and the CT-2 terminal talk with each other through the connected channel.

Description

Adhesive signal processing method of CT-2 for transmission

The present invention relates to a direct incoming call processing method in a cordless telephone-2 (hereinafter referred to as CT-2) system.

In the mobile communication technology field of the communication, the existing CT-2 call-only system does not provide a direct call service to a subscriber, and a method of indirectly receiving a call for processing an incoming call is provided, but in order to connect a call with a called subscriber Since waiting a lot of time, there is a problem that the completion rate of the call required by the subscriber is small.

In order to solve the above problems, an object of the present invention is to provide a direct call service to a subscriber by managing location information of the subscriber in a CT-2 direct call system.

2a to 2c are detailed incoming call processing in the CT-2 system according to the present invention.

In order to achieve the above object, the present invention provides a CT-2 terminal (Cordless Telephone-2 Mobile Station, hereinafter referred to as MS) 10 that provides a CT-2 direct call service, and a CT-2 base station (Cordless Telephone-2 Base Transceiver). System, hereinafter referred to as BS 20, CT-2 Base Station Controller (hereinafter referred to as BSC) 30, CT-2 Switcher (Cordless Telephone-2 Exchange, hereinafter referred to as CTX) (40), the CT-2 subscriber information manager (Cordless Telephone-2 Home Location Register, hereinafter referred to as CTH) 50 sends and receives a message for incoming call processing, and the CTX is a call to the CT-2 terminal If it recognizes, the location information of the terminal is inquired by CTH, and the location information is transmitted and received.

The CTX requests terminal paging with the received location information. When the terminal receives the response, the base station notifies the base station controller and the base station controller notifies the paging response to the CTX.

When the CTX receives the call setting with the CT-2 terminal and connects the wired / wired channel between the called terminal and the CTX, the calling subscriber and the CT-2 terminal make a call through the connected channel.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a hardware configuration diagram to which the present invention is applied, and includes a CT-2 terminal 10, a CT-2 base station 20, a CT-2 base station controller 30, and an access switching processor for cordless telephone. And a CT-2 switch 40 including a Number Translation Processor (hereinafter referred to as NTP) 42 and a CT-2 subscriber information manager 50.

As a software block required for the direct call processing in the CT-2 system, the MS 10 is referred to as a mobile station call control (hereinafter referred to as MCC) for wireless signal control with the BS 20. Block, a BS radio control (BS Radio Interface, RIC) block to control the radio signal with the terminal in the BS 20, BS Signal Control (BS Signal Control, BSBS below) with the BSC 30 The BSC call control (BSC Call Control, BCC) for controlling the CT-2 call and the BSC signal matching (BSC Signal Interface Control, hereinafter referred to as BSIC) block for matching the signal received from the BS 20 to the block and BSC. CTX Call Control (CTX Call Control) block for controlling a call received from the BSC 30 in the ASP, and CTX Number Transfer for translating a number into the NTP 42. (Hereinafter referred to as CTN) block and terminal paging control (CTX Paging Control) Block, and the CT-2 subscriber information manager 50 are mounted with a CTH information control block (hereinafter referred to as HIC) which manages subscriber information.

2A to 2C are detailed flowcharts of direct incoming call processing in a CT-2 system according to the present invention. When NTR receives a “number translation request” message from an outgoing call processing process of CTX (S1), the called party is translated to CT- 2 The subscriber notifies the “CT-2 call notification” message indicating the incoming call (S2).

Upon receiving this, the outgoing call processing process transmits a "called party location information request" message to the HIC of the CTH that manages the information of the CT-2 subscriber to find out the location of the called party (S3).

The HIC of the CTH receives the “requestee location information request” message and inquires the location information of the subscriber (S4), and the “subscriber location information notification” message implementing the location information of the subscriber is the CTX call processing process. Transmit (S5).

The outgoing call processing process transmits a "paging request" message to the CTP to identify the subscriber (S6).

The CTP determines whether the terminal is in use by receiving a "paging request" message for identifying the subscriber location (S7), and terminates an incoming call process (S8).

If the terminal is not in use after the determination, it transmits a "paging request" message requesting terminal paging to the BCC of the BSC in which the terminal is located (S9).

The BCC of the BSC that receives the “paging request” message requesting the terminal paging determines whether the terminal is an authorized terminal (S10), and terminates an incoming call if it is not an authorized terminal (S11). In the case where the terminal transmits a "terminal paging request" message to the BSSC of the BS located (S12).

The BSSC of the BS determines whether a response message has been received from the terminal (S13), when receiving a response message, transmits a “terminal paging response” message to the BCC of the BSC (S14), and when the response message is not received. End the call (S15).

The BCC of the BSC transmits a "paging response" message indicating the terminal location confirmation to the CTP of the CTX (S16).

Receiving a "paging response" message for notifying the terminal location, the CTP transmits a "paging notification" message containing the location information of the terminal to the call signal processing process of the CTC (S17).

CT-2 subscriber call processing process of the CTC receives the "paging notification" message carrying the location information of the terminal to generate the incoming CTC process to perform the incoming call processing (S18).

The called CTC establishes a call channel between the CTX and the BSC to set up an incoming call, and transmits a “call setup” message carrying the same to the BCC of the BSC (S19).

The BSC and the BCC that receive the “call setup” message that sets up the call channel between the CTX and the BSC are called CTCs of the CTX. The call proceeds with the call channel selection requested by the CTC, the new call channel selection, or the call channel selection information. Transmit the message (S20) and complete the call channel setting between the CTX and the BSC (S21).

In addition, the BCC of the BSC transmits a "call setup" message that carries the call channel information for the call setup between the BSC and the BS to the BSSC of the BS (S22).

The BSSC of the BS receiving the “call setup” message transmits a “channel connection” message including information on call channel setup or new call channel setup or call channel setup requested by the BSC to the BCC of the BSC (S23). Complete the call channel setting between the BSC and the BS (S24).

The called CTC receives a "call" message from the BSSC of the BSC (S25) and sends a "ringback tone" to the calling subscriber (S26).

The BSSC of the BS having completed the call channel setting determines the terminal authentication for terminal verification (S27) and terminates the call if the terminal is not an authorized terminal (S28). Complete the setting (S29).

The BSSC of the BS that has completed the wireless call channel setup transmits a "terminal connection" message to the BCC of the BSC (S30).

The BCC of the BSC that has received the "terminal connection" message, which is the wireless call channel setting completion message, transmits a "connection" message informing the terminal response to the CTC of the destination (S31).

The incoming CTC of the CTX receiving the "connect" message indicating the terminal response stops the "ringback tone" sent to the calling party (S32), and the "connect response" message indicating that the "connect" message has been received by the BCC of the BSC. The call is sent (S33), and the call signal processing process connects the call between the calling / calling subscribers by sending an “incoming call” message informing the incoming call (S34).

As described above, the CT-2 direct call system according to the present invention provides the incoming call processing directly to the subscriber to identify the location of the terminal for the call processing to the CT-2 terminal and performs the incoming call setup procedure.

Therefore, the CT-2 direct receiving system provides the subscribers with quick and accurate service, thereby increasing the reliability and efficiency of the CT-2 system.
