Background technology
In telephone call, the state information of circuit is notified the user by the calling procedure sound between switching equipment and the subscriber equipment, and common calling procedure sound comprises dialing tone, busy tone and ring-back tone etc., and they are normally fixedly installed by system.In the prior art, the patent No. is that the PCT patent " Advertising method by using ring-backtone " of WO 00/49793 has proposed a kind ofly to substitute the method for common ring-back tone with the tinkle of bells of network settings, thereby allows network to play advertising message by ring-back tone.At user in this technology the problem of ring-back tone, PCT patent WO 03/071815 " Method and Apparatus forproviding subscriber-based ringback tone " can not be set independently, PCT patent WO2004/023829 " Method for controlling routing information forintellectual peripherals in subscriber-based ring-back toneservice ", U.S. Patent application US 2004/0174983 " Configurable callprogress tones " etc. has proposed a kind of implementation method of personalized ring back tone service.In this type of technology, the own Customized Ring Back Tone that provides to caller when called can be provided the user, comprise and different user group to be set and these users' groups are provided with different ring-back tones according to calling number, and carry out mode of operation such as being provided with of ring-back tone at times.In US2004/0174983, then further propose except that audio frequency, but multimedia messagess such as displaying video, text, picture also.
Fig. 1 has provided above-mentioned personalized ring back tone service or has been called Ring Back Tone service exemplary systems structure, wherein, the control that switching node is responsible for calling out and the exchange of speech channel, the audible ringing tone service service node comprises functions such as Customized Ring Back Tone storage, ring-back tone Play Control, and management node then provides the administration portal of Customized Ring Back Tone customization.Typically, the voice flow that the user provides by Virtual network operator in advance, management process or portal website customize its personalized ring-back tone, when certain calling user dials has customized called subscriber's the number of personalized ring back tone service, by certain signalling interactive process, if called subscriber's free time, the ring-back tone that system promptly sets in advance with the called subscriber replaces the dull ring-back tone of tradition, behind called subscriber's off-hook, system promptly stops playing RBT, and enters normal talking state.
On specific implementation, personalized ring back tone service mainly contains two class implementations: promptly based on the implementation of switch with based on the implementation of intelligent network.Wherein, based on the switch mode be by revise switch software and in switch storage applied for that the user data of Customized Ring Back Tone and ring-back tone realize.And thereby the intelligent network scheme is to have revised the playback process realization personalized ring back tone service of original call flow in original call flow by the intelligent network control mode.
Be different from above-mentioned business by ring-back tone that the called subscriber controls (being called for short the called individual ring-back tone business), Chinese patent application CN1520211 " a kind of calling subscriber of realization answers the method for self-control ring-back tone " has then proposed a kind of business (being called for short the dial individual audible ringing tone service) of calling subscriber's customizing ring-back tone.This business and above-mentioned title called individual ring-back tone business are structurally similar, different is the ring-back tone that is customized oneself by the calling subscriber, promptly when applied for should business user when dialing other people phone, system replaces original dull ring-back tone with the ring-back tone of this user oneself customization, thereby provides the ring-back tone of oneself liking that can independently select for the calling subscriber.
Yet, existing solution all is only limited to the mode of only caller or called custom-made ring-back tone, and according to prior art, provide these two kinds of business may produce conflict simultaneously: promptly when calling subscriber and called subscriber have customized dial individual ring-back tone and called individual ring-back tone respectively, system will be difficult to determine that the ring-back tone of playing and calling order still is a ring-back tone of playing called custom-made.And, according to prior art, there is certain inconsistency on the signaling realization flow of these two kinds of business, promptly not at this two kinds of signaling processes that service optimization is relevant are provided simultaneously, thereby increased the delay of call setup.Therefore, the present invention is directed to the deficiency that prior art exists, the implementation method of the configurable audible ringing tone service of a kind of user has been proposed, ring-back tone when promptly allowing the user to dispose simultaneously and the ring-back tone when called as caller, and realize the method for user's ring-back tone custom service according to set priority.

AWith UE
BRepresent the calling and called subscriber equipment respectively, O_MSC and T_MSC are respectively mobile switching centre and the affiliated mobile switching centre of callee under the calling party, and HLR (attaching position register) is the peculiar network element that is used for storing data such as mobile subscriber business information, mobile network positional information of mobile network.Signaling between RBTS and T_MSC and the O_MSC is used ISUP (ISDNYong Hubufen) agreement, dotted line among the figure is represented may not have the path that directly links to each other between O_MSC and the RBTS, signaling between HLR and T_MSC and the O_MSC is used MAP (MAP) agreement, and what use between RBTS and the SCD is internal interface.
Figure 5 shows that call flow diagram based on the configurable audible ringing tone service of the realization of Fig. 4 system configuration user of the present invention.Its flow process is described below:
1. calling subscriber UE at first
AThe O_MSC of the mobile switching centre request of making a call under caller;
2.O_MSC to HLR request called user information, comprise roaming number and routing iinformation etc., HLR then asks called subscriber's VLR to Provide Roaming Number, and the called user information that gets access to is returned to O_MSC;
3.O_MSC send initial address message IAM to the called T_MSC of mobile switching centre;
4. when the user is in idle condition, send ALERTING message to the called subscriber; If call out unsuccessful, reasons such as for example busy, shutdown, out of reach and calling owing to calling out, and the user is not provided with calling transfer and does not have simultaneously unconditional branch yet, then call out and can not enter audible ringing tone system, give calling subscriber, the resource that system discharges this time calling and distributed but directly play the related announcement sound by O_MSC;
5.T_MSC suppress traditional ring-back tone, and loopback is indicated called ring to Address Complete Message ACM of calling mobile exchanging center O_MSC; O_MSC promptly begins distributing radio resource so that the transmission of ring-back tone and normal talking after receiving ACM message;
6. when O_MSC carry out step 5, it also sent the IAM message of a subsidiary calling number and called number to personalized ring back tone service server RBTS, to ask personalized audible ringing tone service;
7.RBTS after receiving IAM message, extract calling number and called number, and inquiring user customized databank SCD is to obtain the ringback tone information that should play;
8.SCD the calling number of utilization and called number are determined the ring-back tone call number that play and are returned to RBTS based on deterministic process shown in Figure 3;
9.9a-9b.RBTS utilize the ring-back tone call number get access to determine that thereby corresponding ring-back tone memory address begins the playing RBT of appointment, and via the called T_MSC of mobile switching centre, calling mobile exchanging center to calling subscriber UE
AGive this ring-back tone;
10. if there is the physical link that directly links to each other between RBTS and the calling mobile exchanging center, then RBTS can directly send ring-back tone by calling mobile exchanging center O_MSC to the calling subscriber without the called T_MSC of mobile switching centre, as shown in phantom in Figure 5.
11. behind called subscriber's off-hook, terminal called UE
BTo the called T_MSC of mobile switching centre indication called party answer;
12. the called T_MSC of mobile switching centre sends response message ANM to RBTS after receiving the called party answer indication, RBTS stops playing RBT after receiving this ANM immediately;
13. when RBTS sent ANM, it also sent ANM to calling mobile exchanging center O_MSC at the called T_MSC of mobile switching centre.Like this, the calling and called user has just entered normal talking state.
Though above be that example comes the present invention is specifically described with the mobile communication system,, the configurable audible ringing tone service of user proposed by the invention also is suitable in fixed-line telephone network.
