Abstract

PURPOSE: A method for servicing a voice mail reception notice by using a dual stack HLR in a WCDMA network is provided to inform an exchange of a receiver of a voice mail reception notice if the receiver is a 3G mobile communication network subscriber, thereby simply performing a subscriber information confirming procedure. CONSTITUTION: When a new message is stored, a VMS(Voice Mail Service) unit extracts receiver information, and transmits a message requesting a receiver state to be changed to an MSC-V(S200). The MSC-V requests subscriber information to be changed by transmitting a mail state notification message(S201). A D-HLR changes voice mail-related information, and transmits changed results to the MSC-V(S202). The MSC-V transmits the changed results to the VMS unit(S203). A state change notice message is transmitted to an MSC-A(S204). The MSC-A stores subscriber information, and transmits the information(S205). A triggering process request message is transmitted to the D-HLR(S206). A resource is assigned to deliver an announcement(S207), and the announcement is delivered to a subscriber terminal through the MSC-A(S208,S209).

Description

Service method for voice mail delivery notification using dual stack home location register in WCDMA network

The present invention relates to a voice voice mail receiving notification service method for a user of multiple subscribers in a mobile communication network. More specifically, a dual stack home location register in a mobile communication network in which a third generation mobile communication network (WCDMA) and a second generation mobile communication network are mixed. It relates to a voice mail reception notification service method using (D-HLR).

Voice Mail Service (VMS) is a voice mail service (VMS) in situations where the subscriber cannot answer a call (when busy, on power off, in an unavailable area, etc.) and if the caller leaves a voice message. It is a service that allows the voice mail receiver to listen to the other party's voice message by immediately notifying the fact of receipt. In order to provide a voice mail service, the mobile communication network digitizes the voice message input by the sender and stores it in a voice mailbox, and when the receiver wants to check the voice mail, the stored digital data is converted into analog voice and played back.

Such a voice mail service may notify a user of a voice mail immediately when a voice mail is received using a single subscriber in case of a terminal using a single subscriber number. If a voice mail is received by number, there is a disadvantage in that it cannot be notified immediately.

1 is a flowchart illustrating a voice mail reception notification service method for a conventional multi-subscriber number user, in which a caller and a receiver are both second generation mobile communication network subscribers.

Referring to FIG. 1, when a new message is stored in a voice mail service system (VMS) or a subscriber who receives a voice mail checks a voice mail message, the VMS sends a status change message to the mobile telephone exchange (MSC-V). Transmit (S100). Accordingly, the MSC-V transmits a mail state notification message (MailStateNotlfication) including a mail status flag indicating whether a new voice mail is received or confirmed to the home location register (HLR) and requests to change the subscriber's information (S101). The HLR receives the changed state information related to the voice mail of the subscriber and then transmits the result to the MSC-V (S102), and the MSC-V transmits the subscriber information change result to the VMS (S103).

Thereafter, the HLR checks the base station (MSC-A) where the subscriber is currently located and sends a status change fact message (QualificationDirective) to the subscriber to receive the voice mail and store the subscriber information accordingly. In step S104, the MSC-A receives this, stores the information of the corresponding subscriber, and transmits the result to the HLR (S105). In this way, after registering that the unacknowledged voice mail exists to the recipient, when the subscriber attempts to send, the subscriber is notified that the unacknowledged voice mail has been received so that the subscriber can check the voice mail.

As such, when both the sender and the receiver are the same subscribers of the second generation mobile communication network, it is possible to easily notify the voice mail reception to the multiple subscriber number terminal, while the information is transmitted to the map (MAP) standard defined in the 3G network. Since the parameter does not exist, the procedure for notifying the receipt of the unacknowledged voice mail is complicated when the receiver is a subscriber of the third generation mobile communication network. That is, if the receiver is a third generation mobile communication network user, there is a hassle of checking in MSC / VLR or HLR for all callers whether there is an unidentified voice mail when the receiver attempts to make a call.

The present invention has been made to solve the above-mentioned problems, and when the status change request signal is input from the switch to the dual stack home location register according to whether or not the voice mail is received and confirmed, the signal point type of the voice mail receiver is checked, and the voice mail is checked. When the receiver is a 3rd generation mobile network subscriber, the voice mail reception notification service method can be performed to easily perform the subscriber information verification procedure when the 3rd generation mobile network subscriber attempts to send by notifying the voice mail reception fact to the exchange where the receiver is located. There is a technical challenge.

The present invention for achieving the above-described technical problem is a voice mail reception notification service method for multiple subscriber number users in a WCDMA system using a dual stack home location register, when a new voice mail is stored in the voice mail service system, Transmitting, by the voice mail service system, the voice mail reception fact to a first exchanger connected to the voice mail service system; Requesting the first exchange to change the information of the receiver by transmitting a new voice mail fact to the dual stack home location register with reference to the receiver information; The dual stack home location register changing the voice mail related status information of the receiver and transmitting the change result to the first exchange; The dual stack home location register identifies the mobile communication network to which the recipient is subscribed, and if the recipient is identified as a WCDMA system subscriber, retrieves a second exchange that includes the recipient and sends the second exchange to the recipient. Transmitting a status change fact notification message to store the voice mail reception fact; The second exchange changing the state of the receiver and sending the result to the dual stack home location register; When a call origination request is inputted to the second exchanger, it is checked whether the called subscriber is an unidentified voice mail recipient by referring to the state change information of the calling subscriber, and in the case of an unidentified voice mail recipient, the triggering processing request message including the service key indicating the fact. Transmitting to the dual stack home location register; The dual stack home location register determines that there is a voice mail unidentified by the subscriber who attempts to originate from the service key transmitted together with the triggering processing request signal, and allocates a resource for transmitting an announcement for notifying it. ; And transmitting, by the dual stack home location register, the announcement to the calling terminal through the second switch.

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

In the following description, the dual stack HLR 500 integrates and manages a database related to location information such as location registration for 2.5G / 3G subscribers, and functions of the 2.5G home location register and the 3G home location register. For both input signal points according to 2.5G synchronous protocol or 3G asynchronous protocol, two output signal points according to 2.5G synchronous protocol and 3G asynchronous protocol are applied. It searches for information to generate to generate one corresponding output signal point and delivers the corresponding message to the corresponding output signal point.

2 is a flowchart illustrating a voice mail reception notification service method according to the present invention, and illustrates a voice mail reception notification service method when a voice mail is received by a user of a multi-subscriber number subscribed to a third generation mobile communication network.

When a new message is stored in the voice mail service system (VMS), the VMS extracts the called party information and transmits a message requesting to change the status of the called party to the MSC-V connected to the VMS (S200). . Accordingly, the MSC-V sends a mail state notification message (MailStateNotlfication) including a mail status flag indicating whether a new voice mail is received or confirmed to the D-HLR by referring to the called party information and requests the subscriber's information to be changed (S201). After receiving this, the D-HLR changes the voice mail related status information of the subscriber and transmits the result to the MSC-V (S202), and the MSC-V transmits the subscriber information change result to the VMS (S203). ).

At this time, the D-HLR checks the mobile communication network to which the voice mail receiver is subscribed, and if it is identified as the third generation mobile communication network subscriber, the D-HLR searches for the MSC-A currently included in the receiver, and receives the voice mail to the subscriber. The state change fact notification message for storing the subscriber information by reflecting this is transmitted to the MSC-A (S204). Accordingly, the MSC-A stores the information of the subscriber and transmits the result to the D-HLR (S205).

Subsequently, when the subscriber attempts to originate, MSC-A refers to the originating subscriber information to determine whether it is an unidentified voice mail recipient and, if it is an unidentified voice mail recipient, sends a triggering processing request message (InitDP) including a service key indicating the fact. -Transmit to HLR (S206). After the D-HLR determines that there is a voice mail unidentified by the subscriber who attempts to originate from the service key transmitted together with the triggering processing request signal, and allocates a resource for transmitting an announcement for notifying (S207), The announcement broadcasts to the subscriber's terminal through the MSC-A (S208, S209).

When allocating a resource for transmitting an announcement, an IP path address parameter (IPRoutingAddress) for setting a route with an intelligent information providing system of a third generation mobile communication network performing an announcement broadcast function is transmitted together. In addition, when transmitting the announcement, the announcement ID parameter (ElementaryMessageID) including the broadcast announcement ID is transmitted together.

After transmitting the announcement to the subscriber, the MSC-A transmits a message (SpecializedResourceReport) notifying the end of channel setting for the announcement to the D-HLR (S210), and receives the subsequent subscriber's call from the received D-HLR. A message (Continue) for continuing the call processing procedure for the attempt is transmitted to the MSC-A (S211).

When a third generation mobile network subscriber using a multi subscriber number terminal uses a mobile terminal using a subscriber mode of a specific mode, if a voice mail is received using a subscriber number in an unused mode, the subscriber may not recognize that the voice mail has been received. In order to solve this problem, the subscriber will be notified of the announcement when he attempts to make a call. In the present invention, by storing the voice mail reception fact in advance at the exchange including the subscriber, the subscriber information stored in the exchange is referred to the subscriber information stored in the exchange when the subscriber who received the voice mail attempts to call without having to inquire the subscriber information for all callers. Can be notified that the voice mail has been received.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, when a voice mail is received at an unused terminal number of a subscriber of a third generation mobile communication network using the multi-subscriber number of the present invention, the voice is stored to all callers by storing the fact in advance at the exchange including the subscriber. It is possible to notify the receipt of unacknowledged voice mail without checking whether the mail has been received. Accordingly, when the third generation mobile communication network subscriber attempts to make a call, it is possible to solve the need to confirm whether or not there is an unidentified voice mail for all subscribers.
