BRIEF abstract

1 is a schematic structural diagram of a terminal that can block a ringing service (ringing service media data) according to an embodiment of the present invention;

2 is a flow chart of a method for shielding a ringing service according to an embodiment of the present invention.

Preferred embodiment of the invention The basic idea of the present invention is that after receiving the call request message in the process of call setup, the called terminal determines whether to block the ringing service of the ringing server according to the local configuration, and if not, acquires and plays the ringing server indication. Ring media data, if blocked, play a local ring tone. The invention will now be described in detail in conjunction with the drawings and embodiments.

1 is a schematic structural diagram of a terminal that can block a ringing service (ringing service media data) according to an embodiment of the present invention. As shown in FIG. 1, the terminal includes: a call control module, an audio and video playing module, a storage module, and a user interface module. .

The above audio and video playing module is used to play ring tone data.

The storage module is configured to store local ring tone data and ring tone play policy data.

The ring tone playing policy in the ring tone playing policy data may include: a ringing mask flag, a shielded terminal identifier (for example, a terminal number) list, a local ring tone file identifier list, and the like.

The ringing mask mark can take one of the following values: All masks (which can be represented by "1"), Partial masks (which can be represented by "0"), and No masks (which can be represented by "-1").

When the ringing mask is marked as "all masking", the ringing set by all callers is blocked, that is, no ringing set by any calling user is received; when the ringing mask is marked as "unmasked", all calling parties are played. Ringing set by the user, that is, as long as the calling user sets the ringing, the ringing medium set by the calling user is acquired and played; when the ringing mask is marked as "partially shielded", the specified terminal identifier is shielded (ie, the above shielding terminal) Ringing corresponding to the terminal identifier in the identification list.

Of course, an unshielded terminal identifier list may also be set, which includes a terminal identifier that should not block the ringing service; in this case, when the ringing mask flag is "partially shielded", the terminal determines the terminal identifier of the calling terminal. (For example, the calling terminal number) is in the list, if not in the list, the ringing service corresponding to the calling terminal is blocked, and the local ring tone is played.

The local ringtone file identifier list contains the identifier of the available local ringtone file (or local ringtone identifier), and the called terminal can select any local ringtone file (or local ringtone) from the list as the ringing tone. . In addition, the ring tone file identifier (or local ring tone identifier) corresponding to each calling terminal identifier (for example, the calling terminal number) may also be recorded in the list, so that the called terminal according to the calling terminal identifier (for example, the calling terminal) Different numbers are selected for different ringtone files (ie, different local ring tones are selected) for playback. That is, the local ringtone file identification list may be a terminal label. A correspondence table between the identification (for example, the terminal number) and the local ring tone identifier.

The user interface module is configured to provide an interface for setting a ring tone playing policy (ie, modifying ring tone playing policy data). In addition, the user interface module is further configured to send an answering call command or a terminating call command to the call control module.

The call control module is configured to: when the terminal acts as the called terminal, receive a call request message sent by the calling terminal through the ringing server to establish a session with the calling terminal; and when the ring tone playing policy is to block the calling user setting After ringing the media, after receiving the call request message sent by the ringing server, the local ring tone data is extracted from the storage module and sent to the audio and video playing module for local ringing. If the ringing tone policy does not block the ringing tone set by the calling user, the ringing tone media is obtained from the ringing server according to the media indication of the ringing tone carried in the call request message, and the called ringing message is returned. The ringing media obtained from the ringing server is then played.

When the audio and video playing module plays the local ring tone, if the call control module receives the CANCEL message sent by the ringing server, the audio and video playing module is notified to stop playing the local ring tone.

In addition, the call control module may start a timer when receiving the call request message sent by the ringing server, or start playing the local ring tone, and do not receive the answering call command sent by the user interface module before the timer expires or When the call command is terminated, the audio and video playback module is notified to stop playing the local ring tone.

The above modules will be described in more detail below in conjunction with the ringing service screening method of the present invention.

2 is a flowchart of a method for shielding a ringing service according to an embodiment of the present invention; as shown in FIG. 2, the method includes the following steps:

201: The calling terminal sends a call request message to the called terminal. After receiving the call request message sent by the calling terminal, the ringing server adds a media indication of the ringing tone to the call request message, and forwards the message to the called party. terminal.

The above call request message may be a SIP (Session Initial Protocol). INVITE (invitation) message.

The ringing tone is set by the calling user, and the media indication of the ringing tone can be added to the ALERT of the call request message, or the CALL-INFO, or MIME (Multipurpose). Internet Email Extension, a multi-functional Internet mail extension service, is in the style.

202: After receiving the call request message (INVITE message), the called terminal determines, according to the local preset ring tone playing policy, whether to play the ringing tone indicated by the ringing server, if no need to play (ie, the ringing server needs to be blocked) Ringing service), then open the local ring tone file and play the local ring tone as the ringing tone.

If the called terminal (called user) does not need to play the ringing tone indicated by the ringing server, the media of the ringing tone in the ALERT packet header or the CALL-INFO packet header or the corresponding MIME packet body is not parsed. Indication, the ringing tone data set by the calling user is not used, and the called user hears the local ring tone.

On the other hand, if the called terminal (called user) needs to play the ringing tone indicated by the ringing server, the media that resolves the ALERT packet header, or the CALL-INFO packet header, or the ringing tone in the corresponding MIME packet body is parsed. Instruct, and download the media file according to the media indication, or decode the MIME message, and then play the ringing tone set by the calling user. In this case, the called user hears and/or sees the vibration set by the calling user. Ring tone.

203: The called terminal responds to the ringing message; after receiving the ringing message sent by the called terminal, the ringing server forwards the ringing message to the calling terminal.

The above ringing message may be a SIP 180 Ringing message.

Step 203 may be reversed with step 202 or may be performed in parallel. That is to say, after receiving the call request message sent by the ringing server, the called terminal may respond to the ringing message first, and then play the local ring tone according to the ring tone playing policy.

204: After receiving the ringing message (180 Ringing message) sent by the ringing server, the calling terminal sends a pre-acknowledgment message (PRACK message) to the ringing server.

205: After receiving the pre-acknowledgment message sent by the calling terminal, the ringing server returns a response message (200 OK message) of the pre-acknowledgment message to the calling terminal. 206: When the called user answers, the called terminal sends a call response message to the ringing server; after receiving the call response message sent by the called terminal, the ringing server forwards the call response message to the calling terminal.

At this time, if the called terminal is playing the local ring tone as the ringing tone, the called terminal stops playing the local ring tone while the call answer message is sent, and closes the opened ring tone file, ready to receive and play the normal session media message. .

The above call answer message may be a 200 OK message acknowledging the INVITE message of step 201.

207: After receiving the call response message, the calling terminal sends an ACK (acknowledgement) message; after receiving the ACK message sent by the calling terminal, the ringing server forwards the ACK message to the called terminal.

208: The calling terminal and the called terminal talk normally.

The core network in the foregoing embodiment may be an IMS domain of 3GPP (3rd Generation Partnership Project), an MMD (Multimedia Domain) of 3GPP2, and other core networks supporting SIP/IP; The network may be GPRS/EDGE (General Packet Radio Service/Enhanced Data Rate for GSM Evolution), CDMA (Code Division Multiple Access), WCDMA (Wide Code Division Multiple Access), LTE (Long Term Evolution), WiFi (Wireless Fidelity), WiMAX (Worldwide Interoperability for Microwave Access) ), etc., the terminal may be a mobile phone supporting one or more of the above wireless systems.

In the above embodiment, the called terminal responds as an example, and the timing at which the called terminal stops playing the local ring tone is introduced.

In other embodiments of the invention, the called terminal should also stop playing the local ring tone when one of the following occurs:

1) The called terminal receives the CANCEL message sent by the ringing server;

2) The called user suspends (hangs up) the call; 3) The called terminal plays the local ring tone as the ringing tone for more than the preset time length, and the called user does not answer the call. That is to say, when the called terminal receives the call request message, or starts playing the local ring tone, a timer can be started. When the called user does not answer the timer before the timer expires, the local ring tone is stopped.

In addition, in other embodiments of the present invention, the called user can actively turn off the local ring tone by pressing a preset function key or selecting a menu option. After the local ring tone is stopped, the called terminal can parse and save. The media indication of the ringing tone in the call request message (INVITE message) acquires and starts playing the ringing media data sent by the ringing server.

Industrial applicability

Using the shielding method of the ringing service of the present invention and the terminal having the masking ringing function, the called user (called terminal) can locally set the shielding ringing service and select different local bells for different calling numbers. The sound is played, thereby providing a personalized ringing service for the user. In addition, the ringing service shielding method of the present invention does not require any modification to the system side (ringing server), and the cost is low, and does not affect the use of other telecommunication services.
