When a call is not possible due to poor radio environment, battery consumption, power off, etc. The present invention relates to a service for transmitting an incomprehensible message, which informs a pre-recorded message.

In the conventional mobile telephone switchboard, not only the status of the subscriber is not informed when the subscriber does not answer, but only the announcement that the subscriber cannot answer the call.

However, in the CDMA mobile telephone exchange, a voice mailbox system can be used to implement a function of directly recording a subscriber's message. Therefore, in order to satisfy the subscriber's various service needs, there is a demand for a new service that enables a called subscriber to record a voice message to a voice mailbox system and notify the calling subscriber by a voice message.

Therefore, the present invention provides a voice mailbox if a subscriber registered for an undeliverable message transmission service in a CDMA type mobile telephone exchange enters a service code and connects to a voice mailbox system to record a voice, and then the incoming subscriber attempts to make a call. It is an object of the present invention to provide a method for transmitting an incombustible message that can notify the calling subscriber of the recording of the system, and the service subscriber can check and cancel the stored message.

In order to achieve the above object, the present invention provides a method for receiving an incompatibility message transmission service applied to a mobile telephone switch, wherein a subscriber inputs a voice mailbox system when a service registration code for requesting an incompatibility message transmission service is input. A first step of storing a recorded message; A second step of connecting the voice mail system and sending the recorded message recorded by the called subscriber to the calling subscriber if the call is not established due to the inability of the called subscriber to the call to the mobile subscriber; And a third step of connecting a voice mail system to store or delete the current recorded message according to a selection of the subscriber when a service registration code for requesting an incompetent message transmission service is input.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a block diagram of a mobile telephone exchange to which the present invention is applied, where 11 is a switching center, 12 is a base station, 13 is a home location register, 14 is a voice mail system, and 15 is a fax mail system.

The exchange station 11 is composed of a control subsystem (CS), an interconnection subsystem (IS), and a switching subsystem (SS).

CS is responsible for the overall operation and maintenance of the system, and IS is located at the center of the system to connect between SSs or between SS and CS, number translation, and space switch connection. The main function of SS is the call processing function, which exists in one function, but in the application stage, SS-S (Subscriber), SS-T (Trunk), SS-M (Mobile), SS-7 (No.7), SS-A ( ARS), and various combinations of these are possible.

In addition, the switching center 11 includes a control station (BSC) for controlling the base station 12 and a base station management (BSM) for managing functions, and includes a voice mailbox system 14 and a fax mail system. (15) is connected.

The home location register (HLR) 13 is connected to the switching center 11 and functions as a database management system (DBMS) that manages various types of information of mobile subscribers. Perform the function.

12 SS-Ms can be mounted in the switching center 11, and one SS-M can control 16 base stations, so that one switching station can control up to 192 base stations. The base station 12 is a BHIU (Back-Haul Interface Unlt) responsible for the connection between each node (BHIU), Digital Channel Unit (DCHU) for processing various signals, Timing / Frequency Control Unit for generating and distributing synchronization and frequency ) And a Radio Frequency Unit (RFU) for wireless connection with the subscriber and is responsible for various functions for the mobile subscriber.

The CDMA mobile phone subscriber's non-receiving message transmission function is installed in a subsystem in charge of switching of a switch and a VMS Voice Mall Subsystem.

2 is a flowchart of a message recording, confirmation and rush process according to the present invention.

Message Recording The procedure for recording, confirming or canceling a message for the subscriber to receive an out-of-call message is provided when the subscriber presses the service code by using a mobile phone or a public telephone network. The broadcast is provided, and subscribers enter the order in order to complete the service registration, message recording, confirmation, and cancellation. Code for service registration is assumed to be # 00, and use of such code can be changed by the operator.

First, when the calling subscriber enters the service registration code into the mobile phone, the digits input by the batch processing method are received in the call setup message as the silial mobile call processing block (101). The mobile call processing block inquires (102) the Visitor Location Register (VLR) call control block in order to investigate the validity of service provision for the mobile subscriber (calling information inquiry).

The VLR call control block inquires back to the Home Location Register (HLR) containing all the information of the mobile subscriber and notifies the mobile call control block of the result.

The mobile call control block determines the result of the call service validity query (103), releases the call if service is unavailable (103), and proceeds to the initial process, and if service is available, requests for translation of the service code as the number translation block (105).

Subsequently, the service code translation request result is determined (106), if it is an inappropriate code, the call is released (103), and the procedure proceeds to the initial process. 107) If it is an unregistered subscriber, it releases the call (104) and transitions to the initial process, and if it is a registered subscriber, it requests routing information to the VLR (108).

After receiving the VMS representative number from the VLR (109), the number translation control block requests translation of the MSMS (Mobile Subscriber Roaming Number) of the VMS subscriber (110) to determine the MSMS translation request result of the VMS subscriber (111). If the VMS requires the translation and occupancy of the VMS mailbox number (113) and receives the VMS response (114), the connection between the subscriber and the VMS device is completed.

The VMS device provides an announcement to enter a password and * into a path connected to the subscriber (115) to determine the entered password (115-1) and release or reenter the call if an invalid password is input. A password entry announcement may be provided (115) to give a few chances, and if a suitable password is entered, announcement (116) is provided to select to record or confirm and cancel the message. The message can be changed to 1 for recording and 2 for confirmation and cancellation.

After determining the subscriber's selection type (117), if the subscriber selects the message recording, a guide broadcast for inputting the message to be recorded is provided (118). After the subscriber's voice recording is completed (119), all processing is completed, the call is released (104), and the process proceeds to the initial process. Completion of the message input from the subscriber can be recognized using the * code, and this recognition code can be changed and used by the operator.

When the subscriber selects the confirmation and cancellation, the subscriber hears the currently recorded message (120) and inquires whether to keep or delete it (121). After determining the selection type (122), if the user chooses to store the message, he keeps the message (123), releases the call (104), then proceeds to the initial process, and if the message is canceled, deletes the message (124). After releasing 104, the process proceeds to the initial process.

If the VMS subscriber MSRN translation request result is occupied outgoing call and outgoing line occupancy, the VMS mailbox number is transmitted to the large country (112), and the large country processes the same as the processes 113 to 124 of the own country.

As described above, the message recorded in advance by the subscriber is provided to any person who attempts to call the subscriber when the call is impossible.

3 is a flowchart illustrating a procedure for transmitting an incombustible message according to the present invention.

Receiving information about the mobile subscriber according to the call map for the mobile subscriber (201), number translation is requested (202), and when the content of the mobile call is received (203), routing information is requested (204). When the MSRN is received as the routing information (205), the MSRN translation is requested (206), and the MSRN translation request result is determined (207). If the native call is received, the subscriber subscriber information is received (210). If the MSRN translation request result of step 207 is outgoing call and occupied, the called party number is transmitted to the power station (208).

Thereafter, the called party is called (211), in the case of power-off, no response or no-paging, routing information is requested to the VLR (213).

Subsequently, upon receiving the VMS representative number from the VLR (214), the mobile station requester (MSRN) translation of the VMS subscriber is requested to the number translation control block (215) to determine the result of the VMS subscriber MSRN translation request (216). If the request for translation and occupancy of the VMS mailbox number is received (218) and the VMS response is received (219), the connection between the subscriber and the VMS device is completed.

The VMS device transmits an incoming call recording message to the call path connected to the subscriber (220) and releases the call (221).

If the MSMS translation request result of the VMS subscriber of step 218 is occupied by the outgoing call and the outgoing line, the VMS mailbox number is transmitted to the large country (112), and the large country processes the same as the processes 218 to 221 of the own country.

As described above, the present invention generates an effect of automatically answering all calls made to a subscriber in a CDMA mobile telephone exchange, thereby providing maximum convenience to the subscriber and improving subscriber reliability.
