Embodiment

Basic thought of the present invention is, terminal called receives call request message in the process of call setup after, whether shield the ring service of ringing server according to the configuration decision of this locality, if do not shield then obtain and play the ringing media data of ringing server indication, if shielding then play local bell sound.

Describe the present invention below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the terminal of embodiment of the invention maskable ring service (ring service media data), and as shown in Figure 1, this terminal comprises: Call Control Block, audio frequency and video playing module, memory module and Subscriber Interface Module SIM.

Above-mentioned audio frequency and video playing module is used to play the bell sound data.

Above-mentioned memory module is used to store local bell sound data and bell sound broadcast strategy data.

Bell sound broadcast strategy in the above-mentioned bell sound broadcast strategy data can comprise: ring shielding mark, (for example termination number) tabulation of shield terminal sign, local ringtone file identification list etc.

Ring shields mark can get one of following value: all shield (can represent with " 1 "), partly shielding effect (can represent with " 0 "), do not shield (can use " 1 " expression).

When the ring shielding is labeled as " all shieldings ", shield the ring that all calling subscribers are provided with, promptly do not receive the ring that any calling subscriber is provided with; When the ring shielding is labeled as " not shielding ", play the ring that all calling subscribers are provided with, promptly as long as the calling subscriber is provided with ring, just obtain the also ringing media of playing and calling user setting; When the ring shielding is labeled as " partly shielding effect ", (being the terminal iidentification in the above-mentioned shield terminal identification list) the pairing ring of shielding designated terminal sign.

Certainly, non-shield terminal identification list can be set also, wherein comprise the terminal iidentification that should not shield ring service; In this case, when ring shielding was labeled as " partly shielding effect ", whether the terminal iidentification of terminal judges calling terminal (for example, calling terminal number) was in this tabulation, if not in this tabulation then shield the ring service of this calling terminal correspondence, play local bell sound.

Comprised the sign (or local bell phonetic symbol is known) of available local ringtone file in the local ringtone file identification list, terminal called can be chosen local ringtone file (or local bell sound) arbitrarily and play as ring back tone from this tabulation.In addition, can also write down the pairing ringtone file sign of each calling terminal identification (for example calling terminal number) (or local bell phonetic symbol is known) in this tabulation, so that the terminal called ringtone file (promptly select different local bell sound) different according to the different choice of calling terminal identification (for example calling terminal number) play.That is to say that local ringtone file identification list can be the mapping table that terminal iidentification (for example termination number) and local bell phonetic symbol are known.

Subscriber Interface Module SIM is used for providing the interface that bell sound broadcast strategy (promptly revising bell sound broadcast strategy data) is set to the user.In addition, Subscriber Interface Module SIM also is used for sending answer the call order or end call order to Call Control Block.

Call Control Block is used in terminal receiving the call request message that calling terminal sends through ringing server during as terminal called, with set up and calling terminal between session; And when bell sound broadcast strategy is the ringing media of shielding calling subscriber setting, behind the call request message that receives the ringing server transmission, from memory module, extracts local bell sound data, and send to the broadcast that the audio frequency and video playing module carries out local bell sound.If the ring back tone strategy is not shield the ring back tone that this calling subscriber is provided with, then indicate according to the medium of the ring back tone that carries in the call request message, obtain the ring back tone medium from ringing server, after returning called terminal ringing message, play the ringing media that obtains from ringing server.

When the audio frequency and video playing module was play local bell sound, if Call Control Block receives CANCEL (cancellation) message that ringing server sends, then warning tone video playback module stopped to play local bell sound.

When the audio frequency and video playing module was play local bell sound, if Call Control Block receives answer the call order or end call order that Subscriber Interface Module SIM sends, then warning tone video playback module stopped to play local bell sound.

In addition, when Call Control Block can or begin to play local bell sound when receiving the call request message that ringing server sends, start a timer, do not receive answer the call order or end call order that Subscriber Interface Module SIM sends before this timer expiry, then warning tone video playback module stops to play local bell sound.

Above-mentioned call request message can be INVITE (invitation) message of SIP (Session Initial Protocol, initial session protocol).

Ring back tone is provided with by the calling subscriber, the medium indication of ring back tone can be added in ALERT (alarm) heading or CALL-INFO (call information) heading or MIME (Multipurpose Internet Email Extension, multi-functional internet mail expands service) message body of call request message.

202: after terminal called is received call request message (INVITE), the bell sound broadcast strategy that sets in advance according to this locality judges whether the ring back tone that needs broadcast ringing server is indicated, do not play (promptly needing to shield the ring service of ringing server) if do not need, then open local ringtone file, play local bell sound as ring back tone.

If terminal called (called subscriber) does not need to play the ring back tone of ringing server indication, then do not resolve the medium indication of the ring back tone in ALERT heading or CALL-INFO heading or the corresponding M IME message body, the also ring back tone data that just can not use the calling subscriber to be provided with, what the called subscriber heard is local bell sound.

Otherwise, if terminal called (called subscriber) needs to play the ring back tone of ringing server indication, then resolve the medium indication of the ring back tone in ALERT heading or CALL-INFO heading or the corresponding M IME message body, and according to medium indication downloads of media file, or decoding MIME message, the ring back tone that is provided with of playing and calling user then, the called subscriber hears and/or what see is the ring back tone that the calling subscriber is provided with in this case.

203: terminal called is responded ALERTING message; Ringing server is transmitted to calling terminal with it after receiving the ALERTING message of terminal called transmission.

Above-mentioned ALERTING message can be 180Ringing (ring) message of SIP.

Step 203 can with step 202 transposing order, also can executed in parallel.That is to say that terminal called can be responded ALERTING message earlier after receiving the call request message of ringing server transmission, plays local bell sound according to bell sound broadcast strategy again.

204: after receiving the ALERTING message (180Ringing message) of ringing server transmission, calling terminal sends pre-acknowledge message (PRACK message) to ringing server.

205: after ringing server receives the pre-acknowledge message of calling terminal transmission, return the response message (200OK message) of pre-acknowledge message to calling terminal.

206: when the called subscriber answered, terminal called sent call answering message to ringing server; Ringing server is transmitted to calling terminal with it after receiving the call answering message of terminal called transmission.

At this moment,, when terminal called sends call answering message, stop to play local bell sound, close the ringtone file of opening, prepare to receive and play normal conversation media message if terminal called is being play local bell sound as ring back tone.

Above-mentioned call answering message can be the 200OK message that the INVITE of step 201 is replied.

207: after calling terminal receives call answering message, send ACK (affirmation) message; Ringing server is transmitted to terminal called with it after receiving the ACK message of calling terminal transmission.

208: calling terminal and terminal called normal talking.
