Description

A method for transmitting voice information

technical field

The invention relates to mobile network technology, in particular to a method for transmitting voice information.

Background technique

With the rapid development of mobile communication technology, operators provide more and more types of business services for users, and the voice information system service is one of them. Because the voice information system (VMS) has the function of buffering voice, when the user is not in the network and cannot be connected in time if the user is turned off, the mobile switching center MSC can forward the call to the voice information system and directly cache the content of the incoming call. After entering the network, you can listen to incoming calls in the voice information system. Subsequent user operations on the voice information system mainly comply with the voice information system message waiting notification (MWN) and voice message acquisition (VMR) services in the TIA41D MAP protocol.

Fig. 1 is a block diagram of Message Waiting Notification (MWN) in the prior art. Referring to Figure 1, when the user has a buffered voice message, when the user initiates location registration to the network, the home location register HLR will instruct the originating mobile switching center MSC to notify the mobile terminal MS that there is information in the voice information system that needs to be extracted. You can see the corresponding message prompt or voice prompt.

Fig. 2 is a block diagram of a Voice Message Retrieval Service (VMR) in the prior art. Referring to Fig. 2, the called user knows that there is information in the voice information system after receiving the notification from the voice information system, and can access the voice information system by dialing a special number, and the voice information system plays the buffered voice.

For users, there are the following deficiencies in the existing voice information acquisition process: first, the user is not notified of acquiring voice information in time. Because the message waiting notification of the voice information system can be notified by means of short messages, etc., there may be a delay of a certain period of time, and it is not necessarily that the user's location can be known immediately when the user's location is reconnected to the network.

In addition, the user needs to manually operate to obtain the voice. The current operation method requires the user to dial a feature code to initiate a call, and the mobile switching center MSC connects the call to the voice information system, so that the user can hear the voice. This requires the user to remember the feature code, and also increases the inconvenience of operation.

It can be seen that the existing methods for acquiring voice information cannot provide users with voice information in a timely and convenient manner.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for transmitting voice information, so that users can receive voice information in a more timely and convenient manner.

In order to achieve the above object, the technical solution of the present invention is achieved in that:

A method for transmitting voice information, characterized in that the method comprises the following steps:

A. When the originating location of the user terminal is registered in the network, the voice information system VMS is notified;

B. The voice information system VMS initiates a call to call the user terminal;

C. The user terminal connects to the call, and the voice information system VMS plays the buffered voice information to it.

In step A, the voice information system VMS is notified by the home location register HLR.

In step A, the home location register HLR notifies the VMS by extending the message or setting the parameters of the message.

The extended message is a qualification indication message QUALDIR.

The stated parameter is one of the following parameters for the user:

Mobile Subscriber Directory Number MDN, International Mobile Subscriber Identity IMSI, Electronic Serial Number ESN, Mobile Station Identity MIN, Service MSCID.

In step B, the voice information system judges whether there is information that has not been heard in the voice information stored by itself before actively initiating a call.

In step B, the voice information system further judges whether there is information whose content is not empty in the voice information stored by itself before actively initiating a call.

In step B, if the call to the called user is unsuccessful, the user is dialed again, and the VMS realizes the control of the number of calls.

The control of the number of calls by the VMS means that the call fails for two or more consecutive times, and the VMS will not make the call.

In step C, if there are multiple pieces of information, the VMS plays them one by one after adding a voice sequence number in front of the voice information.

This shows that the present invention has the following advantages:

1. In the present invention, when the user can access the network at the first moment when the user is turned off, the VMS actively calls the user, and the user does not need to wait for another message notification, but directly listens to the buffered voice information by connecting the call, so that Users can obtain voice information in a more timely manner.

2. In the present invention, since the user does not need to dial a special number to access to obtain the voice information, the operation for the user to obtain the voice information is simplified.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 3 is a flow chart of the embodiment of the present invention, referring to Fig. 3, adopting qualification indication message QUALDIR to realize the present invention comprises the following steps:

When the subscriber terminal location is reconnected to the network, the mobile switching center MSC sends a location registration message REGNOT to the visitor location register VLR, and the visitor location register VLR notifies the home location register HLR of this message.

The home location register (HLR) finds that the user has registered the voice information calling service, initiates a qualification indication message QUALDIR, and transmits it to the voice information system VMS. The indication message carries the user ID (the user ID includes: mobile subscriber directory number MDN, international mobile subscriber identification code IMSI, electronic serial number ESN, mobile station identification code MIN), service instruction; at the same time, the response message regnot is returned to the visitor location register VLR, and the visitor location register VLR transmits the response to the mobile switching center MSC.

VMS checks the service attribute of the user after receiving the qualification indication message QUALDIR, if it is judged that the user is registered with the voice information service and indicated as a voice information call service, and the voice information has not been read and the content is not empty, then Send a location request message LOCREQ to the home location register HLR according to the mobile subscriber directory number MDN of the calling party to request allocation of a temporary local subscriber number TLDN, and the allocation process is the same as that of a general call.

After receiving the temporary local subscriber number TLDN assigned by the HLR, the VMS calls the mobile switching center MSC, and the calling number is the voice information system number.

If the call is established, the VMS will automatically play the voice information after receiving the response signaling from the called user. If there are multiple pieces of voice information, the VMS will insert a pre-recorded voice sequence number between each voice information and play the multiple pieces of voice information one by one.

Preferably, if the call fails (including all outbound route selection failures, called paging failures, etc.), the VMS controls the number of calls. For example, if there are 3 consecutive failures by saving whether the announcement has been successfully played, the call will not be made.

When the playback is completed or the user hangs up during the listening process, the call is disconnected, and the VMS releases related resources and sets these voices as having been played.

In a word, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
