Table 3
And if terminal called has sent audible ringing tone mark, then play corresponding real-time ring back tone according to this audible ringing tone mark, as the real-time ring back tone in the table 1 1～5, can have the corresponding voice suggestion content about the rejection reason in these real-time ring back tones, for example real-time ring back tone 1 has " user that you dialed just in session " etc.Certainly, all real-time ring back tones not only have the voice suggestion content, can also be voice suggestion, music, song, video display and/or dialogue or the like, its objective is that the called subscriber is when refusing to receive telephone, can also be in time, reasonably explain the reason that can't answer to the calling subscriber, thereby avoided takeing in a wrong spirit or estrangement between calling subscriber and the called subscriber.
In fact, also can be in non-refusing to receive telephone, send audible ringing tone mark and play real-time ring back tone, as between friend, expressing situation at that time in real time,, thereby satisfy customer personalized demand more neatly as mood etc., increase customer satisfaction degree.
Real-time ring back tone of the present invention can be provided or the user uploads by provider, and be stored in the ring-back tone unit, this ring-back tone unit can be independent ringback tone server RBTS, perhaps be located among the MSC of switching center, this ring-back tone unit stores the ring-back tone data of real-time ring back tone sign representative.When the audible ringing tone mark of terminal called is received in this ring-back tone unit, find corresponding real-time ring back tone and send to calling terminal according to this audible ringing tone mark.
In the middle of the reality, the called subscriber can also be according to own different time sections of living in, and automatic or manual transmits different audible ringing tone marks to network side.For example, after 10 of nights, terminal called can feed back an audible ringing tone mark automatically; Normal working hours, terminal called can feed back the another one audible ringing tone mark automatically; On Sunday, terminal called can feed back another different audible ringing tone mark automatically.If the user is answering a phone, also can be by audible ringing tone mark of user's manual feedback, the ring-back tone that changes the audible ringing tone mark correspondence can be to represent the voice suggestion of answering the call.As seen audible ringing tone mark can be according to time, place, personage, incident, mood etc. and is different.
The present invention also provides a kind of terminal called to send the technical scheme of audible ringing tone mark to the called T_MSC of switching center.Here, need on terminal called Called, O_MSC (caller switching center) and/or T_MSC (called switching center), carry out suitable transformation: for example in T_MSC, start the function that collects the digits (existing MSC has forbidden the function that collects the digits at dialing phase) of dialing phase, in the terminal called storage be provided for obtaining and send the application program etc. of audible ringing tone mark.Below how explanation sends to two kinds of methods of network side with audible ringing tone mark, but is not limited thereto.
First kind of scheme sends audible ringing tone mark by the DTMF mode.
A), operate as follows for fixed terminal:
1, terminal called directly sends audible ringing tone mark to T_MSC by the DTMF mode, situation for manual transmission audible ringing tone mark, as audible ringing tone mark is 1 o'clock, can audible ringing tone mark can be sent by " 1 " key that hits on the Telephone set,, acknowledgement key can be required to append certainly for fear of misoperation, as " # " key, promptly need to send audible ringing tone mark, promptly earlier by " 1 " key that hits on the terminal called, again by " # " key by hitting " 1# ".
2, after T_MSC receives the character of certain-length (for example long 2 number lengths) by the parsing dtmf signal, send this audible ringing tone mark that obtains to the ring-back tone unit.
B), operate as follows for portable terminal:
1, terminal called sends a character of audible ringing tone mark to T_MSC by Start DTMF message, situation for manual transmission audible ringing tone mark, a character as audible ringing tone mark is 2 o'clock, can be by hitting the character that " 2 " key on the Telephone set can send audible ringing tone mark.Equally,, can require to append acknowledgement key,, promptly need to send audible ringing tone mark 2 by hitting " 2# " as " # " key certainly for fear of misoperation.
2, after terminal called receives the DTMF Ack that T_MSC returns, send a Stop DTMF to this end office (EO);
3, terminal called sends a character of audible ringing tone mark by Start DTMF to T_MSC again, receive the DTMF Ack that called end office returns after, send a Stop DTMF to this end office (EO), up to whole audible ringing tone marks are sent to T_MSC.Certainly, the form of the character that called mobile terminal also can be by the some length of the disposable transmission of StartDTMF sends audible ringing tone mark.
Second kind of scheme sends audible ringing tone mark by UUS (User to User Singal) signaling or Disconnect message:
The Disconnect message content is as follows: 3GPP TS 24.008:DISCONNECT messagecontent (mobile station to network direction)
| IEI | Information?element | Type/Reference | Presence | Format | Length |
| Call?control protocol?discriminator | Protocol?discriminator 10.2 | M | V | 1/2 | |

| 7F | SS?version | SS?version?indicator 10.5.4.24 | O | TLV | 2-3 |
Terminal called is by some cell in Disconnect message, and for example on behalf of the command code of audible ringing tone mark, User-user cell or Facility cell can will send T_MSC to, and T_MSC obtains corresponding audible ringing tone mark by resolving above cell.
Certainly, terminal called also can be by some cell in the response message, sends the audible ringing tone mark information of correspondence to T_MSC.For example, terminal called also can send to called switching center with audible ringing tone mark by Connect message.
The Connect message content is as follows: 3GPP TS 24.008:CONNECT message content (mobilestation to network direction)
| IEI | Information?element | Type/Reference | Presence | Format | Length |

Terminal called is by some cell in Cconnect message, and for example on behalf of the command code of audible ringing tone mark, User-user cell or Facility cell can will send T_MSC to, and T_MSC obtains corresponding audible ringing tone mark by resolving above cell.
In fact, to obtain audible ringing tone mark can be to import and obtain by the prompting user to terminal called; Also can be to set in advance the corresponding corresponding audible ringing tone mark of predetermined state at terminal called, terminal called be determined corresponding audible ringing tone mark according to current SOT state of termination; Also can be to obtain by the process that the incoming call incident is triggered.For example, the example of prompting user input when terminal is received an incoming call: terminal called is when receiving an incoming call, eject a dialog box, allow the called subscriber import an audible ringing tone mark, show that perhaps a ring-back tone tabulation is for user's selection, and after the user selects corresponding ring-back tone, obtain corresponding audible ringing tone mark; Or the called subscriber opens a dialog box by pre-setting menu when incoming call arrives, and by audible ringing tone mark of this dialog box input, perhaps points out the user to select a ring-back tone from a ring-back tone tabulation.Example according to SOT state of termination: SOT state of termination or pattern that terminal called can set in advance according to the user, return a audible ringing tone mark to network side corresponding to this pattern.For example, the user just in session, terminal can be arranged to conference model, and set in advance under this pattern corresponding audible ringing tone mark, in this case, after terminal called received an incoming call, the audible ringing tone mark with meeting pattern correspondence sent to network side automatically, manually imports audible ringing tone mark and need not the called subscriber; Also for example, terminal called is set in the morning before 8,10 of nights are later on a state, and corresponding audible ringing tone mark 18, like this, terminal is in the morning before 8, after 10 of nights, receiving incoming call is, automatically obtain audible ringing tone mark 18, and the ring-back tone of this audible ringing tone mark correspondence can be: " the automatic You are prompted with of terminal called: the called subscriber is having a rest, if there is not the thing of particular importance; ask contact in second day, thanks! ".
With specific embodiment system and method for the present invention is described below.
Figure 1A is the system configuration sketch of the embodiment of the invention one, and this system not only comprises the HLR of O_MSC, T_MSC, terminal called, further comprises the ringback tone server RBTS that is used to preserve with playing RBT.What present embodiment adopted is the GSM network, and its basic thought can be applied to cdma system or fixed communication network system easily, and its difference only is the difference of concrete message.
The MSC here mainly finishes Service Switching Function and CCF, and O_MSC wherein is calling subscriber's MSC or a GMSC (gateway mobile switching center) (GMSC); T_MSC is called subscriber's a visited MSC, mainly preserves called subscriber's current information, and is accomplished to continuing between the called subscriber in calling procedure.HLR mainly preserves the essential information of portable terminal, comprises real-time ring back tone service profile or the like.
Figure 1B is the signaling process figure of the embodiment of the invention one.
Step 102～103, HLR learns that according to called number this called subscriber is real-time ring back tone service contracting user; And HLR sends the request of obtaining called roaming number to T_MSC, and T_MSC sends to HLR with MSRN then for the called subscriber distributes a roaming number MSRN.
Step 106～108, T_MSC sends to terminal called Called with this IAM; The T_MSC paging is called, and when terminal called is in idle condition, called state information is sent to O_MSC by Address Complete Message ACM (Address Complete Message); If the current state of terminal called is not idle, for example busy, shutdown or out of reach, then T_MSC by O_MSC to the calling terminal transparent transmission represent that the user is busy, the voice suggestion of shutdown or out of reach.
In step 110, RBTS obtains the acquiescence ring-back tone, sends ACM to O_MSC then.Here, when terminal called did not also send audible ringing tone mark, O_MSC notice RBTS earlier sent the acquiescence ring-back tone, pairing ring-back tone when promptly audible ringing tone mark is empty.When the acquiescence ring-back tone is when being provided with according to called number, RBTS can be an acquiescence ring-back tone of searching called subscriber's customization according to this called number.
Step 111, RBTS plays this acquiescence ring-back tone by O_MSC to calling terminal, the traditional ringback sound that the T_MSC of O_MSC shielding simultaneously plays.
Step 112, terminal called are obtained an audible ringing tone mark and are sent this audible ringing tone mark to T_MSC, and being connected of general automatic disconnection of T_MSC here and terminal called, promptly terminal called is no longer by ringring prompting; Can certainly not automatic disconnection and being connected of terminal called, but disconnect being connected of terminal called and T_MSC by on-hook key by the called subscriber, perhaps realize that by answering key the speech channel of calling and called connects, and promptly handles according to existing procedure.It can be to obtain by prompting called subscriber input that terminal called obtains audible ringing tone mark, also can be the audible ringing tone mark of basis at the correspondence of terminal current state or pattern of living in setting, is obtained automatically by terminal.
Step 113～114, T_MSC sends to O_MSC with this audible ringing tone mark; O_MSC sends to RBTS with audible ringing tone mark again.
Step 116, RBTS plays this real-time ring back tone to calling terminal by O_MSC, stop to play the acquiescence ring-back tone simultaneously, the audio frequency that has comprised called subscriber's refusing to receive telephone in this real-time ring back tone is explained, like this, owing to explain in time, can avoid takeing in a wrong spirit between called subscriber and the calling subscriber, estrangement or unhappy greatly.
Fig. 2 A is the system configuration sketch of the embodiment of the invention two, and different with Figure 1A is, the RBTS of embodiment two only is connected with T_MSC, and the RBTS of embodiment one only is connected with O_MSC, and promptly embodiment two is by the broadcast of T_MSC control real-time ring back tone.
Fig. 2 B is the signaling process figure of the embodiment of the invention two.
Step 101～108 of step 201～208 and embodiment one are basic identical, unique different be that the called subscriber does not customize the acquiescence ring-back tone, but send traditional ring-back tone, i.e. the bell sound of " pouting ... pout ... " by T_MSC.Certainly, also can be the same to embodiment one, terminal called has customized corresponding acquiescence ring-back tone.
Step 209, T_MSC sends the traditional ringback sound to O_MSC, and this traditional ringback sound finally passes through calling terminal by O_MSC.
Step 210～211, terminal called obtain an audible ringing tone mark and send this audible ringing tone mark to T_MSC, and T_MSC sends to RBTS with this audible ringing tone mark again.It can be to obtain by prompting called subscriber input that terminal called obtains audible ringing tone mark, also can be the audible ringing tone mark of basis at the correspondence of terminal current state or pattern of living in setting, is obtained automatically by terminal.
Step 212, RBTS searches corresponding real-time ring back tone according to this audible ringing tone mark, sends ACM to T_MSC then.
Step 213, RBTS plays this real-time ring back tone by T_MSC, O_MSC to calling terminal, stops to play the traditional ringback sound simultaneously.Certainly, the scheme that also can adopt RBTS directly to play to O_MSC, RBTS at this moment is general, and requirement has CCF, knows owing to this scheme belongs to those skilled in the art, so repeat no more.
Step 214, when the calling subscriber hangs up the telephone, O_MSC receives that this hangs up information and send to T_MSC.Also can be after real-time ring back tone be play reasonable time execution in step 215.
Step 215, T_MSC sends the REL signaling to RBTS, cuts off the route between T_MSC and the RBTS immediately, thereby stops to play real-time ring back tone to calling terminal.
Fig. 3 A is the system configuration sketch of the embodiment of the invention three, and this system only comprises O_MSC, T_MSC, HLR, and does not possess RBTS, because embodiment two adopts T_MSC to preserve and play the scheme of real-time ring back tone.
Fig. 3 B is the signaling process figure of the embodiment of the invention three.
Step 101～108 of step 301～308 and embodiment one are basic identical, unique different be that the called subscriber does not customize the acquiescence ring-back tone, but send traditional ring-back tone, i.e. the bell sound of " pouting ... pout ... " by T_MSC (built-in ring-back tone unit).Based on same reason, also can send traditional ring-back tone by O_MSC.
Step 309, T_MSC gives calling terminal by O_MSC transparent transmission traditional ringback sound.
Step 310, terminal called are obtained an audible ringing tone mark and are sent this audible ringing tone mark to T_MSC; It can be to obtain by prompting called subscriber input that terminal called obtains audible ringing tone mark, also can be the audible ringing tone mark of basis at the correspondence of terminal current state or pattern of living in setting, is obtained automatically by terminal.
Step 311, T_MSC searches corresponding real-time ring back tone according to this audible ringing tone mark, and the real-time ring back tone that is somebody's turn to do to calling terminal of T_MSC stops to play the traditional ringback sound simultaneously then.Here, owing to utilize the T_MSC storage and play real-time ring back tone, the cost that may cause end office (EO) to transform is higher.
Step 312, when the calling subscriber hangs up the telephone, O_MSC sends the REL signaling to T_MSC, cuts off the route between O_MSC and the T_MSC immediately, thereby stops to play real-time ring back tone to caller.After also can playing the real-time ring back tone appropriate time, for example 1 minute, T_MSC stopped playing RBT automatically.And after stopping to play real-time ring back tone, each embodiment of the present invention all can select whether to play traditional prompt tone to O_MSC, as " called subscriber can't connect " etc.
Fig. 4 A and Fig. 4 B are the signaling process figure of the embodiment of the invention four, and its system configuration sketch is shown in Figure 1A.Embodiment four needed to judge whether terminal called has sent audible ringing tone mark in the section at the fixed time before playing the acquiescence ring-back tone, then play real-time ring back tone if receive audible ringing tone mark, otherwise play the acquiescence ring-back tone.
Step 401～408 are identical with step 101～108 of embodiment one.
Step 409, O_MSC reserved a period of time (for example 5 seconds) and judges whether terminal called sends audible ringing tone mark before notice RBTS plays the acquiescence ring-back tone, and, the traditional ring-back tone that needs shielding T_MSC to play.If receive audible ringing tone mark, then carry out step 410 and follow-up flow process thereof shown in Fig. 4 A.Otherwise carry out step 420 and subsequent step thereof shown in Fig. 4 B.Certainly, if the called subscriber do not customize the acquiescence ring-back tone, then can temporarily shield traditional ringback sound a period of time and judge by O_MSC.The benefit of doing like this is can avoid the calling subscriber to hear two kinds of ring-back tones, because might cause obscuring or discomfort of calling subscriber like that.
Step 412, RBTS plays this real-time ring back tone by O_MSC to calling terminal.
In the step 420 shown in Fig. 4 B, O_MSC does not receive the audible ringing tone mark that terminal called sends in the preset time section, then sends IAM to RBTS, and by this IAM information such as calling number, called number is sent to RBTS.
Step 421, RBTS obtains the acquiescence ring-back tone, sends ACM to O_MSC then.When the acquiescence ring-back tone is when being provided with according to called number, RBTS can be an acquiescence ring-back tone of searching called subscriber's customization according to this called number.
Step 422, RBTS plays this acquiescence ring-back tone by O_MSC to calling terminal.So far, just can be used as the complete scheme of embodiment four, hang up or give tacit consent to ring-back tone when caller and be played to the scheduled time, then stop to play, O_MSC cuts off and being connected of calling terminal.
When playing the acquiescence ring-back tone here certainly, if terminal called has sent audible ringing tone mark, O_MSC can receive, and also can not receive.Receive step 423 and the subsequent step thereof of scheme shown in Fig. 4 B of audible ringing tone mark.
Step 423～425, when RBTS by O_MSC during calling terminal sends the acquiescence ring-back tone, T_MSC receives the audible ringing tone mark that terminal called sends; T_MSC transfers to O_MSC with this audible ringing tone mark; O_MSC sends to RBTS with this audible ringing tone mark again.
Step 427, RBTS plays this real-time ring back tone by O_MSC to calling terminal, stops to play the acquiescence ring-back tone simultaneously.
More than the purpose of four embodiment, all be to be used for the explanation that the called subscriber answers refusal.But in fact, the called subscriber can also send different audible ringing tone marks in real time according to actual conditions at that time, network side selects corresponding real-time ring back tone to send to the calling subscriber according to this audible ringing tone mark, after playing reasonable time, receive calls again, send the real-time ring back tone of state (mood etc.) at that time between the friend for example mentioned above, to satisfy user's demand neatly, the perhaps subscriber call ring-back tone demand of waiting a moment, concrete scheme is as described in the embodiment five.
Fig. 5 is the signaling process figure of embodiments of the invention five, and wherein step 501～516 are basic identical with step 101～116 among the embodiment one, so repeat no more.What unique possibility was different is that in step 512, after terminal called sent audible ringing tone mark, the maintenance of T_MSC palpus was connected with terminal called.
Step 517～518, after terminal called was replied, T_MSC sent to O_MSC with response message ANM.
Step 520, the normal speech channel of setting up between the calling and called by O_MSC and T_MSC connects.
What deserves to be mentioned is, in the various embodiments of the present invention, if RBTS plays described acquiescence ring-back tone (or traditional ringback sound) and reaches predetermined amount of time: and terminal called does not send audible ringing tone mark or still dont answer or calling terminal on-hook not yet of terminal called yet; Then stop playing RBT, and end call connects by caller switching center and/or called switching center notice ring-back tone unit.In addition, the present invention and existing customization of ring back tone service do not clash, and those skilled in the art are easy to realize the real-time ring back tone business again on the basis of former customization audible ringing tone service.
Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection range of accompanying Claim of the present invention.
