Table 5

Certainly, also caller name and phone number property territory can be set simultaneously in the audible ringing tone mark tabulation, then can directly in the audible ringing tone mark tabulation, search corresponding audible ringing tone mark according to the calling number in the call request.

In addition, can also be in terminal be that caller is provided with audible ringing tone mark at different scenes.The audible ringing tone mark tabulation for example can be set respectively under every kind of scene, also can in the audible ringing tone mark tabulation, increase scene identity row, at a calling subscriber, the audible ringing tone mark that different scene identity is corresponding different.Above-mentioned scene can be proper communication scene, refusing to receive telephone scene, meeting scene, time of having a rest scene etc.The current scene sign then can be set in terminal, after terminal receives call request, search corresponding audible ringing tone mark in conjunction with the current scene sign according to the calling number in the call request.The Custom Ringback sound that the user is can also be at different scene setting different, and the Custom Ringback sound that is provided with uploaded in the ring-back tone unit of network side, the ring-back tone unit distributes audible ringing tone mark for user-defined ring-back tone, then, the audible ringing tone mark that this user sets the Custom Ringback sound of uploading for the user in the ring-back tone unit is again downloaded to get off to be used for corresponding caller is provided with, thereby can be at different scenes, different calling subscribers in terminal, the Custom Ringback sound is set neatly, has further satisfied user's individual demand.

Described scene can be special time or particular space.Not necessarily to set the current scene sign this moment in advance, but can when receiving incoming call, obtain current scene information temporarily or judge current scene by terminal called.

For example scene described in the present invention can be that time range is set, for example, it is a time range that morning 22:00 to the second day night 7:00 is set, like this, when a calling occurred between the 7:00 in morning 22:00 to the second day night, current scene was exactly this time range.Obviously, terminal called can obtain this scene information automatically.Obviously, those skilled in the art are easy to expect, terminal called can be that a time range scene is distributed a scene identity, are 2207 with the time scene allocation identification between morning 22:00 to the second day night 7:00 for example.

Scene described in the present invention can also be a spatial dimension, and for example, it is spatial dimension that meeting room can be set, and like this, receives one when calling out when called this meeting room the inside that is connected on, and current scene is exactly this spatial dimension.Called receiving when calling out can be obtained current spatial information, by current spatial information and the meeting room spatial information that relatively obtains, judges whether current calling belongs to this spatial dimension.The mode that terminal is obtained spatial information can be to have the called subscriber to import by hand, for example, and input in advance, or input when going into to call out generation; The mode that terminal is obtained spatial information also can be at terminal called the spatial information deriving means to be set, obtain spatial information by this device, specifically the application number that can submit before this referring to the applicant is CN02125256.4, denomination of invention is the patent application document of " a kind of sign of physical object and recognition methods ", repeats no more here.Equally, those skilled in the art are easy to expect that terminal called can distribute a scene identity for a spatial dimension scene, is 13 with meeting chamber spatial scene allocation identification for example.

Above-mentioned time range can be set to discontinuous, for example, time range can be set to morning 22:00 to the second day night 7:00 and daytime 12:30 to the 14:00 union of two time periods.

Equally, spatial dimension can be set to discontinuous, and for example, spatial dimension can be set to the intersection in a plurality of meeting rooms and a plurality of performances Room.

In addition, the user can also further manually be provided with audible ringing tone mark, then status indicator need be set in terminal, being used to identify current is to obtain the state that audible ringing tone mark sends to the state of network side or manually audible ringing tone mark sent to network side by the user automatically, for example the status indicator of She Zhiing is 0 o'clock, and sign sends audible ringing tone mark automatically; Status indicator is 1 o'clock, and sign manually sends audible ringing tone mark.Then terminal is after receiving call request, and at first query State identifies, if status indicator is 0, then terminal is obtained audible ringing tone mark automatically and returned to network side; Otherwise, wait for that the user manually returns audible ringing tone mark.Be provided with by this, the user can remember several audible ringing tone marks commonly used, under the situation of needs, during as meeting, can manually return different ring-back tones at different calling subscribers.

More than how terminal called is provided with audible ringing tone mark for different callers, and how obtain audible ringing tone mark and have been described in detail according to the call request that receives.The called switching center that more how terminal called is sent to audible ringing tone mark network side is elaborated below.

Provide two kinds of terminals to transmit the scheme of audible ringing tone mark among the present invention, be respectively by the Dual Tone Multifrequency mode and send audible ringing tone mark and send two kinds of schemes of audible ringing tone mark by signaling to the called switching center of network side, below explanation respectively.

First kind of scheme transmits audible ringing tone mark by the DTMF mode.

A) for fixed network, it is as follows to transmit the ring-back tone method:

1, terminal called directly sends audible ringing tone mark to called switching center 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 called switching center received the character of certain-length by the parsing dtmf signal, for example the character of long 2 number lengths sent this audible ringing tone mark that obtains to the ring-back tone unit.

Here need to prove that for existing fixed communication network, fixed terminal needs to set up earlier to be connected with the speech channel of called switching center, connects by this speech channel and could use the DTMF mode to send audible ringing tone mark to called switching center.Called switching center is after setting up the speech channel connection, do not set up with the speech channel of caller switching center and be connected, but the wait terminal called is uploaded audible ringing tone mark, after receiving user's audible ringing tone mark, send this audible ringing tone mark to the ring-back tone unit, simultaneously can disconnect or not disconnect called switching center and be connected with speech channel between terminal called; And called switching center just sends connection response to caller switching center after receiving the off-hook order that the user sends in the DTMF mode, sets up to be connected with the speech channel of caller switching center.For example, terminal called was set up and after being connected of called switching center, when audible ringing tone mark being sent to called switching center by the DTMF mode, do not show that the called subscriber has answered phone, and when called subscriber's off-hook receives calls, terminal called can send an off-hook order by the DTMF mode to called switching center once more, after this off-hook order is received by called switching center, just send connection response, and send the message that stops to play corresponding ring-back tone to RBTS to caller switching center.

Certainly, terminal called also can send described audible ringing tone mark to called switching center by frequency shift keying (FSK) mode.Detailed process can repeat no more here with reference to the DTMF mode.

B) for the mobile network, it is as follows to transmit the ring-back tone method:

1, terminal called sends a character of audible ringing tone mark to called mobile switching centre (T_MSC) by beginning dual-tone multifrequency (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 T_MSC receives character, return dual-tone multifrequency response (DTMF Ack) message to terminal called.

3, after terminal called receives the DTMF Ack message that T_MSC returns, send one to this end office (EO) and stop dual-tone multifrequency (Stop DTMF) message.

4, terminal called sends a character of audible ringing tone mark again to T_MSC by Start DTMF, after receiving the DTMF Ack that called end office returns, send a Stop DTMF to this end office (EO), and then repeat to send the step of Start DTMF message, 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 Start DTMF sends audible ringing tone mark.

Certainly, terminal called also can send described audible ringing tone mark to called switching center by the FSK mode.

Second kind of scheme, by usertouser signalling (User to User Singal, UUS) or disconnect to connect (Disconnect) message and send audible ringing tone mark:

The portable terminal of regulation is as shown in table 6 to the Disconnect message content (3GPP TS 24.008:DISCONNECT message content (mobile station to networkdirection)) of network side in 3GPP TS 24.008, the content wherein and the meaning of representative thereof are the agreement regulation, known for those of ordinary skills, no longer describe in detail here.

Table 7

Terminal called is by some cell of Connect 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.

Need to prove that called interaction center is being received this Connect message, is used for transmitting audible ringing tone mark if judge this message, then called interaction center can not handled it as connection message.Like this, terminal called can be in the follow-up Connect message that sends once more, and do not carry described audible ringing tone mark in this message, to express connection response.Certainly, when passing through the described audible ringing tone mark of Connect message bearing, further whether carrying is the sign that disconnects response message, and like this, called interaction center judges whether it is to disconnect response message according to this sign, if, then after obtaining described audible ringing tone mark, carry out opening operation and handle, otherwise, as mentioned above, it is not handled as connection response message, and obtain corresponding audible ringing tone mark.

After T_MSC obtains audible ringing tone mark, send audible ringing tone mark to the ring-back tone unit.Here reaching above-mentioned ring-back tone unit can be independent ringback tone server RBTS, also can be the built-in ring-back tone unit of being located among the MSC of switching center, all stores the pairing ring-back tone of audible ringing tone mark in the ring-back tone unit in any case be provided with.After audible ringing tone mark is received in the ring-back tone unit, find corresponding ring-back tone and the ring-back tone that is found is sent to caller according to this audible ringing tone mark.

Below by specific embodiment the present invention is described.

Fig. 2 A be one of the embodiment of the invention based on the system configuration sketch, this system not only comprises the attaching position register (HLR) of calling mobile exchanging center (O_MSC), T_MSC, terminal called, further comprises the RBTS that is used to preserve with playing RBT.Present embodiment and follow-up each embodiment are based on global system for mobile communications (GSM) network, and its basic thought can be applied to code division multiple access (CDMA) communication 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 ring back tone service contracting information etc.

Fig. 2 B is the signaling process figure of the embodiment of the invention one.

Step 201, after O_MSC receives phone call request from caller, send request (SRI) message of the routing iinformation that obtains the called subscriber to the HLR of called subscriber's ownership, this request message comprises called subscriber's information such as called number, and the called number here can be terminal comprehensive service digital net number (MSISDN) or other called terminal number.

Step 202～203, HLR learns that according to called number this called subscriber is the ring back tone service contracting user, sends the request of obtaining called roaming number to T_MSC then, T_MSC returns to HLR with MSRN then for the called subscriber distributes a roaming number MSRN.

Step 204, HLR sends to O_MSC by obtaining called route requests response (SRI_Ack) message with called MSRN and ring back tone service contracting information.

Step 205, O_MSC sends an initial address message (IAM) to T_MSC.The IAM here comprises calling number, called number and called MS RN.

Step 206, this IAM is sent to terminal called to T_MSC and paging is called.

After step 207, terminal called receive call request, obtain corresponding audible ringing tone mark and this audible ringing tone mark is sent to T_MSC according to the calling number in this call request.Terminal called obtains audible ringing tone mark, and the part that is embodied in before the present embodiment that audible ringing tone mark sends to T_MSC is elaborated no longer explanation here.If the current state of terminal called is not idle, for example busy, shutdown or out of reach, then T_MSC by paging called obtain terminal called and be in busy state after, by O_MSC to the caller transparent transmission represent that the user is busy, the voice suggestion of shutdown or out of reach.

Step 208, T_MSC will pass through Address Complete Message, and (Address Complete Message ACM) sends to O_MSC from the audible ringing tone mark of terminal called.

Step 209, O_MSC sends IAM to RBTS, and by this IAM information such as calling number, called number and audible ringing tone mark is sent to RBTS.

Step 210, RBTS searches corresponding ring-back tone according to receiving audible ringing tone mark, sends ACM to O_MSC then.

Step 211, RBTS plays the ring-back tone that is found by O_MSC to caller.

Step 212, when the calling subscriber hangs up the telephone, or behind called off-hook, when receiving response message from T_MSC by O_MSC, O_MSC sends release message (Release, REL) signaling to RBTS, cut off immediately and RBTS between route, thereby stop to the caller playing RBT.Certainly, O_MSC can also preset the reproduction time value of ring-back tone, and for example 1 minute, the time was cut off route between O_MSC or the RBTS automatically to back O_MSC.

Fig. 3 A is the system configuration sketch of the embodiment of the invention two, and different with Fig. 2 A 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 ring-back tone.

Fig. 3 B is the signaling process figure of the embodiment of the invention two.

Step 301～307 are basic identical with step 201～207 of embodiment one, and in step 308, T_MSC directly sends to coupled RBTS with audible ringing tone mark.

Step 309, RBTS searches corresponding ring-back tone according to this audible ringing tone mark, sends ACM to T_MSC then.

Step 310, RBTS plays this ring-back tone by T_MSC, O_MSC to caller.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 311, when the calling subscriber hangs up the telephone, O_MSC receives that this hangs up information and send to T_MSC, after perhaps the terminal called off-hook is replied, T_MSC sends the REL signaling to RBTS, cuts off the route between T_MSC and the RBTS immediately, thereby stops to the caller playing RBT.

Fig. 4 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 present embodiment adopts ring-back tone unit built-in among the T_MSC to preserve and playing RBT.

Fig. 4 B is the signaling process figure of the embodiment of the invention three.

Step 401～407 are basic identical with step 201～207 of embodiment one, and in step 408, T_MSC searches corresponding ring-back tone according to the audible ringing tone mark that receives, and T_MSC plays this ring-back tone by O_MSC to caller then.

Step 409 when the calling subscriber hangs up the telephone, sends the TEL signaling by O_MSC to T_MSC, and perhaps after the terminal called off-hook was replied, T_MSC stopped to the caller playing RBT.After also can the playing RBT appropriate time, for example 1 minute, T_MSC stops playing RBT automatically.And after stopping playing RBT, 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.

More than the present invention among each embodiment, before step 208,308 and 408, whether T_MSC can further to knowing that called state is to receive from effective audible ringing tone mark of terminal called in the predefined time of idle back to judge, if then carry out above-mentioned step 208,308 and 408; Otherwise T_MSC directly transmits traditional ring-back tone to O_MSC.Above-mentioned come self terminal be the audible ringing tone mark of null value, do not belong to effective audible ringing tone mark.In addition, if above-mentioned judgement structure is for denying, T_MSC can also be set to null value by audible ringing tone mark in step 208,308 and 408, after then the ring-back tone unit receives audible ringing tone mark into null value, the acquiescence ring-back tone that called subscriber in this ring-back tone unit sets in advance is play to caller.

What deserves to be mentioned is, in the various embodiments of the present invention, reach predetermined amount of time if the ring-back tone of acquiescence or non-acquiescence is play in the ring-back tone unit, and terminal called does not send audible ringing tone mark or still dont answer or caller 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.

Be appreciated that the above only for preferred embodiment of the present invention, or not within the spirit and principles in the present invention not all in order to restriction the present invention, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
