Abstract

PURPOSE: A method for copying inter-VMS(Voice Mailing System) voice mail information in a paging system is provided to enable voice mail information to be reproduced between VMSs in a paging system. CONSTITUTION: In case that a voice information copy request is transmitted from a calling VMS(VMS#1) to a called VMS(VMS#2)(200), a calling VMSC requests a WAPS block to extract ASP and LN information for a DN(202). Then the calling VMSC checks whether a req_flag is set to "1"(204). In case that the req_flag is "0", the calling VMSC executes non VMS subscriber processing for an associated LN of a PSC block(206). Then the calling VMSC requests connection for a copy function to the called VMS(208). A called VMSC establishes access for the copy function, transmits a VMS termination request to the called VMS and receives a result(210). The VMS termination request result is transmitted to the calling VMSC. In response to the result, the calling VMSC connects a space switch with the called VMSC(212) and notifies it of the called VMSC. Then the calling VMSC connects a time switch to the space switch, and informs the calling VMS that a call path has been connected(214). Also the called VMSC connects a time switch to the space switch, and informs the called VMS that the call path has been connected(216).

Description

How to copy voice mail information between V.M.S. of paging system {METHOD FOR COPYING VOICE MAIL INFORMATION BETWEEN VMS OF PAGING SYSTEM}

The present invention relates to a voicemail system, and more particularly, to a method for copying voice information switching between voicemail systems connected to a paging exchange system.

In general, a voice mail system (VMS / Voice Mail Service / Voice Mailing System) refers to a service system that stores a voice message or receives a stored voice message through a telephone by using voice digitization and transmission technology. It is a technology that is generally serviced in mobile phones and personal mobile phones.

However, the conventional voicemail system does not have a function of copying voice information between VMSs, so that when a voicemail service in a predetermined area is concentrated, there is no function for distributing it. Also, the load of each voicemail system decreases rapidly. Even if this is reduced, there was a problem that can not be integrated and managed.

It is therefore an object of the present invention to provide a method for copying voicemail information between VMSs in a paging system.

The present invention for achieving the above object is a method for copying the voicemail information between the VMS of the paging system, when the request for copying the voicemail information from the originating VMS to request a copy function connection to the incoming VMS And, if there is a response from the destination VMS to the connection request, connecting a path between the originating VMS and the destination VMS in a call, and copying voicemail information of the originating VMS to the destination VMS through the call path. Characterized in that it comprises a process to make.

2 is an operation control flowchart for copying voicemail information between VMSs according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the reference numerals to the components of the accompanying drawings, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. Also in the following description and in the accompanying drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a configuration diagram of a paging exchange system connected with a plurality of voicemail systems (VMS) to which an embodiment of the present invention is applied. Referring to FIG. 1, the paging exchange system is configured to send / receive VMS # 1 (100) / VMS # 2104 and a paging exchanger 102 to transmit / receive a VMS message according to an embodiment of the present invention. It is composed.

The PNDH block 114 in the NTP unit 104 manages subscriber information generation / change / deletion. The WAPS block 116 calculates the ASP number in which the DN (subscriber) is registered. The PSC block 118 in the ASP section 106 performs VMS block / unblock processing on the DN. The VMSCs 110 and 112 open the paths between VMS # 1 and 2 (100 and 104) and control the flow of each signal.

Referring now to the operation, first, when the originating VMS # 1 (100) has the incoming VMS # 2 (104) ID, ASP number, DN and req_flag information and requests the VMT (Voice Mail Transfer) function, the destination VMSC (112) the corresponding DN Checks for validity. Subsequently, the ASP 106 with the PSC block 118 that handles the DN is searched and the general number pager processing is performed on the DN. When this function is being performed, the external telephone is not received by the VMS # 2 104. Do not This prevents the VMS # 2 104 mailbox information from being changed while the VMT is running. With the requested ASP 106 and VMS ID, the destination VMSC 112 is informed if it is possible to perform the VMT function of the incoming VMS # 2 104, and if possible, a space switch and a time to connect the path to the call. A time switch is connected, and the incoming VMSC 112 also connects a time switch to connect a path through a call and performs a voicemail copy function to each VMS. Subsequently, when the originating VMSC 110 receives a notification that the copy function is normally performed in the originating VMS # 1 100, the originating VMSC 110 notifies the destination VMSC 112 of the release of the path by the call and releases the space switch and the time switch. The terminating VMSC 112 then releases the time switch and notifies the terminating VMS # 2 104 that the copy has been completed successfully. The originating VMSC 110 requests and modifies the DB modification to the PNDH block 114 to access the terminating VMS # 2 104 that the VMS information for the DN is supposed to access the originating VMS # 1 100. When this is done, the PSC block 118 in charge of call processing for the DN is notified. Therefore, if all the copying process is normally performed, all the voicemail information for one subscriber is transferred to the destination VMS # 2 104 by notifying the originating VMS # 1 100 of the copy successful result. On the other hand, if an error occurs in the middle of the error, the termination procedure restores all system resources as much as the progress and handles the copy failure.

2 is a flowchart illustrating an operation of copying voice information between voicemail systems according to an exemplary embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

First, when the voice information copy request is received from the originating VMS # 1 100 to the incoming VMS # 2 104 in step 200 of FIG. 2, the originating VMSC 110 proceeds to step 202 and the WAPS block ( 116) Request the ASP and LN information registered subscriber information by using the DN as a key. The originating VMSC 110 then checks whether req_flag is set to "1" in step 204. At this time, the originating VMSC 100 restores the VMS information to the previous subscriber when the req_flag is "1", and proceeds to the copy function when the req_flag is "0".

Therefore, when the req_flag is "1", the originating VMSC 110 proceeds to step 226. In contrast, when the req_flag is "0", the originating VMSC 110 proceeds to step 206 and the PSC block 118 is performed. ) Handles the change request subscriber VMS and non-VMS. The originating VMSC 110 then requests a connection to the destination VMS # 2 104 for a copy function at step 208. Accordingly, the incoming VMSC 112 establishes a connection for the copy function to the incoming VMS # 2 104 in step 210, requests the incoming VMS to the incoming VMS # 2 104, and receives the result. do.

Subsequently, the VMS incoming request result is transmitted to the originating VMSC 110 again. In step 212, the originating VMSC 110 connects a space switch with the incoming VMSC 112 in response to the VMS incoming request result. The incoming VMSC 112 is notified. In step 214, the originating VMSC 110 connects the time switch to the space switch and notifies the originating VMS # 1 100 of the path connection to the call. The incoming VMSC 112 also connects the time switch to the space switch in step 216 and notifies the incoming VMS # 2 104 of the call connection with the pass. Accordingly, the voicemail information is copied through the path of the call connected between the calling VMS # 1 100 and the called VMS # 2 104.

Thereafter, if the copy is successfully performed, the originating VMS # 1 100 notifies the originating VMSC 110 of the copy termination in step 218. Then, the originating VMSC 110 proceeds to step 220 and the called VMSC proceeds. Notify the end of copying at 112 and release the space switch and time switch to release the pass with the connected call. Accordingly, the destination VMSC 112 releases the path in the call with the originating VMSC 110 in step 222 and notifies the destination VMS # 2 104 of the completion of the copy. Subsequently, the originating VMSC 110 notifies the PNDH block 114 that the incoming VMS information has been changed in step 224 to modify the VMS information of the DN from the originating VMS # 1 (100) to the incoming VMS # 2 (104). do. The originating VMSC 110 proceeds to step 226 to perform the VMS call processing to the PSC block 118, and notifies the originating VMS # 1 100 of the copy success in step 228.

Therefore, it is possible to copy voicemail information between VMS through the paging exchange system.

As described above, in the present invention, in the case of operating a plurality of VMSs in a paging exchange system, when the load is not properly distributed due to the change of each VMS subscriber, some of the VMS subscribers may be moved to another VMS to distribute and operate the VMS loads. There is this. In addition, when the number of VMS subscribers is reduced and there is no need to operate multiple VMSs, the voice mailbox information is copied to another VMS as is and the information about the VMS accessed by the exchange system is changed to access the copied VMS. The advantage of being able to integrate is the efficient use of system resources.
