For technical scheme and advantage is more clearly understood, develop simultaneously embodiment referring to the drawings, and the present invention is described in more detail.

In the embodiment of the present invention is logical, when terminal called receives the incoming call requests of calling terminal, terminal called can send a ring-back tone indicated value Gei Wang Network side, and the ring-back tone unit of network side sends corresponding ring-back tone to calling terminal in real time according to the ring-back tone indicated value.

For real-time ring back tone business, called subscriber can carry out the registration of real-time ring back tone business by way of being contracted to business hall, can also dial special number or by Internet by way of carry out the registration of the business.

Above-mentioned ring-back tone indicated value can be audible ringing tone mark or cause value, illustrate respectively with regard to both of these case below.

Embodiment one：Ring-back tone indicated value is audible ringing tone mark

In order to realize real-time ring back tone business, corresponding ring-back tone preserved according to audible ringing tone mark in ring-back tone unit, as shown in table 1： Audible ringing tone mark ring-back tone

1 real-time ring back tone 1

2 real-time ring back tones 2

3 real-time ring back tones 3

4 real-time ring back tones 4

5 real-time ring back tones 5

If terminal called do not send or send audible ringing tone mark it is invalid when, i.e., audible ringing tone mark for sky

(NULL), corresponding is the default ring back tone of setting or the traditional ringback sound of system, and default ring back tone or traditional ringback sound can be now sent by ring-back tone unit to calling terminal.

Default ring back tone is can be set for all calling terminals, at this moment, and same ring-back tone is all only corresponded to for any calling terminal；Default ring back tone can also be set only for individual caller terminal, at this moment, a default ring back tone corresponding table of caller one can be set up according to calling identification, as shown in table 2.In table, calling terminal identification is the communicating number of calling subscribe（ MSISDN ).So, the real-time ring back tone of acquiescence will be determined according to calling terminal identification in RBTS.

The default ring back tone of table 2 is can be set for all terminal calleds, at this moment, and same ring-back tone is all only corresponded to for any terminal called；Default ring back tone can also be set only for indivedual terminal calleds, at this moment, a called default ring back tone corresponding table can be set up according to called identification, as shown in table 3.In table 3, terminal called mark is the communicating number of called subscriber（MSISDN ).So, the real-time ring back tone of acquiescence will be determined according to terminal called mark in RBTS. Called identification default ring back tone is identified

Table 3

And if terminal called have sent audible ringing tone mark, corresponding real-time ring back tone is then played according to the audible ringing tone mark, such as the real-time ring back tone 1 ~ 5 in table 1, there can be the corresponding voice message content on reason for access denial in these real-time ring back tones, such as real-time ring back tone 1 has " user that you are dialed is just in session ".Certainly, all real-time ring back tones not only have voice message content, it can also be voice message, music, song, video display and/or dialogue etc., the purpose is to called subscriber in rejection phone, the reason for can not answering can also be explained to calling subscribe in time, reasonably, so as to avoid takeing in a wrong spirit between calling subscribe and called subscriber or estrangement.

In fact, can also send audible ringing tone mark to play real-time ring back tone when non-rejection phone, real-time table, so as to more neatly meet customer personalized demand, is increased customer satisfaction degree up to situation, such as mood at that time such as between friend.

Embodiment two：Ring-back tone indicated value is cause value

It is similar with a upper embodiment, set in ring-back tone unit and preserve cause value-ring-back tone corresponding table, i.e., by reason for access denial（For example just in session, other phones etc. are answered）Or other are worth the reason for situation is set to different at that time, different audible ringing tone marks are selected further according to the cause value, as shown in table 4：

If the terminal called of table 4 is no or does not also send cause value, i.e., cause value is sky（NULL), corresponding is that the default ring back tone set is identified or the traditional ringback phonetic symbol of system is known, and now can send default ring back tone by ring-back tone unit or traditional ringback sound be sent to calling terminal.And if terminal called have sent original Because of value, corresponding real-time ring back tone is then played according to the cause value, there can be the corresponding voice message content on reason for access denial in real-time ring back tone 1-5 in such as table 1, these real-time ring back tones, such as real-time ring back tone 1 has " user that you are dialed is just in session ".Certainly, all real-time ring back tones not only have voice message content, it can also be voice message, music, song, video display and/or dialogue etc., the reason for can not answering is explained to calling subscribe in time, reasonably the purpose is to called subscriber, so as to avoid takeing in a wrong spirit between calling subscribe and called subscriber or estrangement.

In fact, can also send cause value to play real-time ring back tone when non-rejection phone, real-time table is up to situation, such as mood at that time such as between friend, so as to more neatly meet customer personalized demand, increase customer satisfaction degree, with reference to shown in table 5.

Table 5

Real-time ring back tone in the embodiment of the present invention can be provided by provider or user uploads, and it is stored in ring-back tone unit, the ring-back tone unit can be single ringback tone server RBTS, or in switching centre MSC, the ring-back tone unit is stored with the representative ring-back tone data of real-time ring back tone mark.When the ring-back tone unit receives the ring-back tone indicated value of terminal called, corresponding real-time ring back tone is found according to the ring-back tone indicated value and calling terminal is sent to.

Among actual, called subscriber can also transmit different ring-back tone indicated values according to different time sections residing for oneself, automatic or manual to network side.For example, after 10 points of night, terminal called can be with one ring-back tone indicated value of automatic feedback；Normal working hours, terminal called can be with another ring-back tone indicated value of automatic feedback；Sunday, terminal called can with automatic feedback another different ring-back tone indicated value., can also be by one ring-back tone indicated value of user's manual feedback if user is answering a phone, the corresponding ring-back tone of ring-back tone indicated value can be the voice message for representing answering the call.It can be seen that ring-back tone indicated value can be different according to time, place, personage, event, mood etc.. The embodiment of the present invention also provides a kind of terminal called and sends ring-back tone indicated value to the technical scheme of called switching centre (T-MSC).Here, it is necessary in terminal called Called, 0-MSC (caller switching centres）And/or T-MSC (called switching centres）It is upper to carry out appropriate transformation：Start the function that collects the digits of dialing phase for example in T-MSC（Existing MSC prohibits the function that collects the digits in dialing phase）, stored in terminal called and be provided for obtaining and send the application program etc. of audible ringing tone mark.It is described below how ring-back tone indicated value is sent to the two methods of network side, but not limited to this.

The first scheme, ring-back tone indicated value is sent by DTMF modes.

A) for fixed terminal, operate as follows：

1st, terminal called directly sends ring-back tone indicated value to T-MSC by DTMF modes, when sending ring-back tone indicated value manually,, can be by hitting on Telephone set when such as ring-back tone indicated value being 1 " Γ, key can send ring-back tone indicated value; of course for avoiding maloperation; can require to add acknowledgement key, such as " # " key, that is, need that ring-back tone indicated value can be sent by hitting " 1# "; first press " 1 " key hit on terminal called, then button.

2nd, T-MSC is received by parsing dtmf signal after the character of certain length (such as growing 2 number lengths), sends the obtained ring-back tone indicated value to ring-back tone unit.

B) for mobile terminal, operate as follows：

1st, terminal called sends a character of ring-back tone indicated value by Start DTMF message to T-MSC, when sending ring-back tone indicated value manually, when a character such as ring-back tone indicated value is 2, can press " 2 " key hit on mobile terminal can send a character of ring-back tone indicated value.Equally, it in order to avoid maloperation, can require to add acknowledgement key, such as " # " key, that is, need that ring-back tone indicated value 2 could be sent by hitting " 2# ".

2nd, terminal called is received after the DTMF Ack of T-MSC returns, and a Stop DTMF is sent to the end office (EO);

3rd, terminal called sends a character of ring-back tone indicated value by Start DTMF to T-MSC again, after the DTMF Ack for receiving called end office return, a Stop DTMF is sent to the end office (EO), is sent until by whole ring-back tone indicated values to T_MSC.Certainly, called mobile terminal can also disposably send the form of the character of some length to send ring-back tone indicated value by Start DTMF.

Second scheme, passes through UUS (User to User Singal) signalings or separation（Disconnect) message sends ring-back tone indicated value： Disconnect message contents are as follows： 3GPP TS 24.008:DISCONNECT message content (mobile station to network direction) (the mobile Disconnect message contents for accounting for network direction）

Terminal called passes through some cells in Disconnect message, such as User-user cells or Facility cells, the command code for representing ring-back tone indicated value can be sent to T-MSC to, T-MSC obtains corresponding ring-back tone indicated value by parsing above cell.

Certainly, terminal called can also be by some of response message cell, by corresponding ring-back tone indicated value information transmission to T-MSC.For example, ring-back tone indicated value can also be sent to called switching centre by terminal called by Connect message.

Connect message contents are as follows： 3GPP TS 24.008: CONNECT message content (mobile station to network direction) IEI cells type/parameter

Terminal called by some cells in Cconnect message, for example User-user cells or

Facility cells, can send the command code for representing ring-back tone indicated value to T-MSC, and T-MSC obtains corresponding ring-back tone indicated value by parsing above cell.

In fact, it can be by pointing out user's input to obtain that terminal called, which obtains ring-back tone indicated value,；Can also be that the predetermined corresponding ring-back tone indicated value of state correspondence is pre-set in terminal called, terminal called determines corresponding ring-back tone indicated value according to the current SOT state of termination；It can also be a process being triggered by calling event to obtain.For example, the example that prompting user inputs when terminal is connected to an incoming call：Terminal called is when receiving an incoming call, a dialog box is ejected, allows called subscriber to input a ring-back tone indicated value, or one ring-back tone list of display is selected for user, and after user selects corresponding ring-back tone, obtain corresponding ring-back tone indicated value；Either called subscriber opens a dialog box when sending a telegram here arrival by pre-setting menu, and a ring-back tone indicated value is inputted by the dialog box, or prompting user selects a ring-back tone from a ring-back tone list.According to the example of the SOT state of termination：The SOT state of termination or pattern that terminal called can be pre-set according to user, a ring-back tone indicated value for corresponding to the pattern is returned Xiang Wang Network sides.For example, user is just in session, conference model can be set the terminal to, and pre-set corresponding ring-back tone indicated value under the pattern, in this case, after terminal called receives an incoming call, the corresponding ring-back tone indicated value of conference model is sent to network side automatically, without called User manually inputs ring-back tone indicated value；Also for example, setting terminal called is in the morning before 8 points, it is a state after 10 points of night, and correspondence ring-back tone indicated value 18, so, terminal is in the morning before 8 points, after 10 points of night, it is to automatically derive ring-back tone indicated value 18 to receive incoming call, and the corresponding ring-back tone of ring-back tone indicated value can be：" the automatic You are prompted with of terminal called：Called subscriber is in rest, if without especially important thing, asking contact in second day, thanks！ " .

Illustrate the system and method for the present invention with specific embodiment below.

Figure 1A is the system architecture sketch of the embodiment of the present invention one, and the system not only includes 0-MSC, T-MSC, the attaching position register of terminal called（), HLR further comprise for preserving the ringback tone server with playing RBT（RBTS ).The present embodiment uses GSM net Network, and its basic thought can be conveniently used in CDMA systems or fixed communication network system with blunt, and it differs only in the difference of specific message.

Here the main finishing service functions of exchange of MSC and CCF, 0_MSC therein is the MSC or GMSC of calling subscribe（ GMSC );T-MSC is the visited MSC of called subscriber, the main current information for preserving called subscriber, and is accomplished in calling procedure continuing between called subscriber.HLR mainly preserves the essential information of mobile terminal, including real-time ring back tone service profile etc..

Figure 1B is the signaling process figure of the embodiment of the present invention one.

Step 101, when 0-MSC receives the phone call request from calling terminal, the HLR belonged to called subscriber sends the request SR1 for obtaining the routing iinformation of called subscriber, the information such as called number of the request bag containing called subscriber, i.e. the called MSISDN of called number here.

Step 102 ~ 103, HLR learns that the called subscriber is real-time ring back tone service contracting user according to called number；And HLR sends the request for obtaining called roaming number to T-MSC, T-MSC is that called subscriber distributes a mobile client roaming number（MSRN), MSRN is then sent to HLR.

Step 104, called MSRN and real-time ring back tone service profile are sent to 0-MSC by HLR by SRI-Ack message.

Step 105, O-MSC sends an initial address message to T_MSC（IAM：).Here IAM includes calling number, called number and called MS RN.

The IAM is sent to terminal called by step 106-108, T-MSC（Called );T-MSC pagings are called, and when terminal called is in idle condition, called status information totally disappeared by address Breath ACM (Address Complete Message) is sent to O-MSC;If the current state of terminal called is not idle, for example, hurries, shut down or out of reach, then T-MSC represents busy user, shutdown or the voice message of out of reach by 0-MSC to calling terminal transparent transmission.

Step 109, O-MSC sends IAM to RBTS, and the information such as calling number, called number are sent into RBTS by the IAM.It is that playing RBT is controlled by O-MSC in the present embodiment.

Step 110, RBTS obtains default ring back tone, then sends ACM to O-MSC.Here, when terminal called does not also send ring-back tone indicated value, O-MSC first notifies RBTS sends default ring back tone, i.e. ring-back tone indicated value to be the ring-back tone corresponding to space-time.When default ring back tone be according to called number to set when, RBTS can be searched according to the called number called subscriber customization default ring back tone.

Step 111, RBTS plays this default ring back tone by O-MSC to calling terminal, while the traditional ringback sound that O-MSC shieldings T-MSC is played.

Step 112, terminal called obtains a ring-back tone indicated value and sends the ring-back tone indicated value to T-MSC, here T-MSC-as it is automatic disconnect and terminal called connection, i.e. terminal called is no longer rung prompting；The connection with terminal called can not certainly be disconnected automatically, but by called subscriber is disconnected the connection of terminal called and T-MSC by on-hook key, or realize that the speech channel of calling and called is connected by Answer Key, i.e., handled according to existing procedure.It can be by pointing out called subscriber's input to obtain or according to the corresponding ring-back tone indicated value set for terminal current state or residing pattern, automatically derived by terminal that terminal called, which obtains ring-back tone indicated value,.

The ring-back tone indicated value is sent to O-MSC by step 113 ~ 114, T-MSC;Ring-back tone indicated value is sent to RBTS by 0-MSC again.

Bu Sudden 115, RBTS search corresponding real-time ring back tone according to the ring-back tone indicated value, then send ACM to calling switchboard center.

Step 116, RBTS plays this real-time ring back tone by O-MSC to calling terminal, stop playing default ring back tone simultaneously, the audio that called subscriber's rejection phone is contained in the real-time ring back tone is explained, so, because solution Dry is obtained in time, takeing in a wrong spirit between called subscriber and calling subscribe, estrangement or unhappy can be avoided significantly.

Step 117, when calling subscribe hangs up the telephone, O-MSC sends release message REL (Release) signaling to RBTS, immediately the route between cut-out and RBTS, so as to stop playing real-time to caller Ring-back tone.Certainly, 0-MSC can also preset the reproduction time value of real-time ring back tone, and such as 1 minute, the time automatically cut off the route between 0-MSC or RBTS to rear 0-MSC.

Fig. 2A is the system architecture sketch drawing of the embodiment of the present invention two, from unlike Figure 1A, the RBTS of embodiment two is only connected with T-MSC, and the RBTS of embodiment one is only connected with OJ SC, i.e., embodiment two is controlled the broadcasting of real-time ring back tone by T-MSC.

Fig. 2 B are the signaling process figure of the embodiment of the present invention two.

Step 201 ~ 208 and step 101 ~ 108 of embodiment one are essentially identical, it is unique unlike called subscriber do not customize default ring back tone, but traditional ring-back tone is sent by T-MSC, i.e., " beep ... is beeped ..., tone.It is of course also possible to which to as embodiment one, terminal called has customized corresponding default ring back tone.

Step 209, T-MSC sends traditional ringback sound to O-MSC, and the traditional ringback sound finally passes through calling terminal by O-MSC.

Step 210 ~ 211, terminal called obtains a ring-back tone indicated value and sends the ring-back tone indicated value to T-MSC, and the ring-back tone indicated value is sent to RBTS by T_MSC again.It can be by pointing out called subscriber's input to obtain or according to the corresponding ring-back tone indicated value set for terminal current state or residing pattern, automatically derived by terminal that terminal called, which obtains ring-back tone indicated value,.

Step 212, RBTS searches corresponding real-time ring back tone according to the ring-back tone indicated value, then sends ACM to T-MSC.

Step 213, RBTS passes through T-MSC；, 0-MSC play the real-time ring back tone to calling terminal, while stop play traditional ringback sound.It is of course also possible to use the scheme that RBTS is directly played to O-MSC, RBTS at this moment-as require that there is CCF, because the program belongs to as it is known to those skilled in the art that therefore repeating no more.

Sudden 214 is walked, when calling subscribe hangs up the telephone, 0-MSC receives the hook information and is sent to T-MSC.Step 215 can also be performed after real-time ring back tone plays reasonable time.

Bu Sudden 215, T-MSC send REL signalings to RBTS, and the route between T-MSC and RBTS is cut off immediately, so as to stop playing real-time ring back tone to calling terminal.

Fig. 3 A are the system architecture sketch of the embodiment of the present invention three, and the system only includes 0-MSC, T-MSC, HLR, without possessing RBTS, because the present embodiment preserves and played the scheme of real-time ring back tone using T-MSC. Fig. 3 B are the signaling process figure of the embodiment of the present invention three.

Step 101 ~ 108 of step 301-308 and embodiment one are essentially identical, uniquely the difference is that called subscriber does not customize default ring back tone, but by T-MSC (built-in ring-back tone units）Send traditional ring-back tone, i.e., " beep ... is beeped ..., tone.Based on same reason, traditional ring-back tone can also be sent by 0-MSC.

Step 309, T_MSC by 0_MSC transparent transmission traditional ringback sounds to calling terminal.

Sudden 310 is walked, terminal called obtains a ring-back tone indicated value and sends the ring-back tone indicated value to T_MSC;It can be by pointing out called subscriber's input to obtain or according to the corresponding ring-back tone indicated value set for terminal current state or residing pattern, automatically derived by terminal that terminal called, which obtains ring-back tone indicated value,.

Step 311, T-MSC searches corresponding real-time ring back tone, the real-time ring back tone that then T-MSC is somebody's turn to do to calling terminal according to the ring-back tone indicated value, while stopping playing traditional ringback sound.Here, due to real-time ring back tone is stored and played using T-MSC, the cost for being likely to result in end office's transformation is higher.

Bu Sudden 312, when calling subscribe hangs up the telephone, 0-MSC sends REL signalings to T-MSC, and the route between 0 one MSC and T-MSC is cut off immediately, so as to stop playing real-time ring back tone to caller.It can also play after real-time ring back tone appropriate time, such as 1 minute, T-MSC was automatically stopped playing RBT.And after stopping playing real-time ring back tone, each embodiment of the invention can choose whether to play traditional prompt tone to O-MSC, such as " called subscriber is not turned on, etc..

Fig. 4 A and Fig. 4 B are the signaling process figure of the embodiment of the present invention four, and its system architecture sketch drawing is as shown in Figure 1A.Example IV, it is necessary to judges whether terminal called have sent ring-back tone indicated value within a predetermined period of time, real-time ring back tone is played if ring-back tone indicated value is received, default ring back tone is otherwise played before default ring back tone is played.

Step 401 ~ 408 are identical with step 101 ~ 108 of embodiment one.

Step 409, OJVISC is reserved for a period of time, such as 5 seconds before notifying RJBTS to play default ring back tone, to judge whether terminal called sends ring-back tone indicated value, furthermore, it is desirable to shield traditional ring-back tone of 1 ^ euro broadcastings.If receiving ring-back tone indicated value, Bu Sudden 410 and its follow-up process as shown in Figure 4 A are performed.Otherwise perform step 420 as shown in Figure 4 B and continue step Sudden thereafter.Certainly, if called subscriber does not customize default ring back tone, can for a period of time it be judged by OJVISC temporarily shields traditional ringback sound.Advantage of this is that, calling subscribe can be avoided to hear two kinds of ring-back tones, because that Sample is possible to cause obscuring or uncomfortable for calling subscribe.

Step 410,0-MSC sends IAM to RBTS, and the information such as calling number, called number and ring-back tone indicated value are sent into RBTS by the IAM.

Step 411, RBTS searches corresponding real-time ring back tone according to called number, then sends ACM to 0-MSC.

Step 412, RBTS plays the real-time ring back tone by 0-MSC to calling terminal.

Step 413, when calling subscribe hangs up the telephone（Can also be that real-time ring back tone was played after certain time）, 0-MSC sends REL signalings to RBTS, immediately the route between cut-out and RBTS, so that stopping to caller 4 times puts real-time ring back tone. '

In step 420 as shown in Figure 4 B, 0-MSC does not receive the ring-back tone indicated value of terminal called transmission in predetermined time period, then sends IAM to RBTS, and the information such as calling number, called number are sent into RBTS by the IAM

Step 421, RBTS obtains default ring back tone, then sends ACM to O-MSC.When default ring back tone be according to called number to set when, RBTS can be searched according to the called number called subscriber customization default ring back tone.

Step 422, RBTS plays the default ring back tone by O-MSC to calling terminal.So far, it is possible to as the complete scheme of example IV, when caller is hung up or default ring back tone is played to the scheduled time, then stop playing, O-MSC cut-outs and the connection of calling terminal.

When playing default ring back tone here certainly, if terminal called have sent ring-back tone indicated value, O-MSC can be received, and can not also be received.Receive the scheme step 423 as shown in Figure 4 B and its subsequent step of ring-back tone indicated value.
