Description

A kind of communication system and implementation method that produces Customized Ring Back Tone
Technical field
The present invention relates to a kind of communication equipment platform, may operate in mobile radio communication and the fixed-line telephone network, make the calling subscriber in the time of waiting for called subscriber's off-hook, can hear Customized Ring Back Tone, as music, tone information etc., and no longer be the stand by tone of the dullness in the black phone, the invention still further relates to the implementation method of this personalized ring back tone service.
Background technology
Current telecommunications network, comprise mobile network and fixed network, as: GSM network [moving and UNICOM], cdma network [UNICOM], PSTN network [telecommunications and Netcom] and PHS network [telecommunications and Netcom], in the whole communication process, all be adopt acquiescence dullness " too ... pout " ring-back tone, the ring-back tone of all communication networks conversations is all identical.
The broadcast of ring-back tone is after setting up the PCM link between calling and called, and switch is that the sound of " pouting ... pout " is play in caller before the called off-hook, informs that the caller speech channel connects, and behind called off-hook, switch cuts off ring-back tone, caller and called normal talking.When user's long time no answer, after then ring-back tone is play the longest ring-back of such conversation, cut off speech channel.According to international norm and industry standard requirement, the longest ring-back tone is different, in the mobile network: the longest duration of calling ring-back tone between the mobile network is 45s, and it is 60s that fixed network is called out the longest duration of mobile network ring-back tone broadcast, and it is 120s that international long-distance is called out the longest duration of ring-back tone broadcast; Call out fixed network playing RBT duration, it is 45s that the normal conditions ring-back tone is play the longest duration.
Along with telecommunication service constantly develops, also grow up based on the value-added service of telecommunications network, various personalized services are subjected to people's welcome.
When people made a phone call, also wishing to have a kind of ring-back tone of personalization to provide, and makes in the communication stand-by period, hears melodious music or interesting language, rather than traditional " too " the standard ring back tone.Individual audible ringing also has extraordinary application prospect in commercial field simultaneously, as company's propaganda, product introduction and client resources management etc.
Present Ring Back Tone Technology implementation has according to the speech channel branch: speech channel polyphone solution and the speech channel solution of taking out stitches.According to the network configuration branch: isolated node solution, switch solution and intelligent network solution.To realize that at present Customized Ring Back Tone mainly contains two kinds of methods: speech channel polyphone solution, the solution of taking out stitches.
Speech channel polyphone solution
By the solution of speech channel polyphone solution Ring Back Tone service, its network structure such as Fig. 1, call flow
1, call out called B (ring-back tone service customization person) as caller A, caller MSC goes to inquire about routing iinformation and the business attribute information of called B to HLR;
2, HLR is after judging that called B has applied for audible ringing tone service, with calling transfer to the CRBT center [CRBT system].Detailed process is as follows: HLR is with MSRN[or TLDN] number translated becomes MSRN ' [or TLDN '], specific practice is for MSRN[or TLDN] in the number preceding 2 (86) become other specific characters [as (00)], be about to MSRN[or TLDN] number: 8613xxxxxxxxx becomes MSRN ' number: 0013xxxxxxxxx.HLR returns specific MSRN ' [or TLDN '] for caller MSC.
3, caller MSC routes the call to the CRBT system, the CRBT system is through handling, obtain user roaming information, send real calling to called B, after the called B response, the CRBT system is to caller A playing RBT, when called B off-hook normal talking then, after A and the end of B normal talking, the CRBT system will take out stitches.
This scheme is less relatively to the existing network index word, needs switch to do the data setting, so that route the call to the CRBT system; And need sign to apply for this business in the user of HLR, and whether user's service condition activates.
This scheme has special requirement to HLR, requires HLR can realize MSRN[or TLDN] number translated becomes MSRN ' [or TLDN '], and manufacturer does not support this function.The versatility of this solution is relatively poor, and needs the special cooperation of main equipment manufacturer.
This solution has expended a large amount of PCM traffic resources, the color ring systems serial connection need be entered whole logical
In the words process.Its shortcoming is as follows:
1, versatility is relatively poor:
Support that the switch manufacturer of this scheme is few, and the software version of its system is had requirement, at the provide support Ring Back Tone service of this scheme of its equipment, need upgrade if desired, need a large sum of upgrade cost, and upgrade cycle is longer old equipment.
2, cycle of commencing business is long.For the telecommunication market of fierceness, carrying out new business fast is an important means striving for the client.Such scheme needs main equipment that cooperation is provided, and whole engineering will be lasted longer.
The solution of taking out stitches [switch solution]
In the scheme of taking out stitches of CRBT, Service Node connects MSC with the PCM link, and other MSC in the service area visits this Service Node, its network structure such as Fig. 1 by the signalling point address.After ring-back tone finished playing, MSC sent and releases order, and indication disconnects and connecting, and MSC changes normal talking over to, its network structure such as Fig. 2.Dial with fixed-line subscriber that to be the mobile subscriber be example, concrete calling procedure is as follows:
(1) after the calling party transferred to callee's number (MSISDN), to nearest GMSC (GMSC (gateway mobile switching center)), GMSC sent query messages SRI to obtain routing iinformation to HLR to fixed network with this call proceeding.
(2) HLR needs the inquiring user state table, determines whether the user has applied for the CRBT business, should business whether be activated simultaneously.If the user does not apply for that CRBT business or business are not activated, and then handle by normal conversation.
(3) if HLR judge user applies professional and this business of CRBT be in state of activation, Ring Back Tone service is arranged and whether roaming etc. has taken place.
(4) HLR sends PRN request roaming number message to MSC/VLR, and MSC/VLR distributes roaming number MSRN and returns to HLR by PRN ACK.
(5) HLR requires the roaming number of user B to MSC/VLR, MSC/VLR returns the routing iinformation of user B to HLR, HLR after the caller switch is received the routing iinformation of user B, sends initial address message IAM to MSC/VLR with the switch at its subscriber call A place.
(6) MSC requires to carry out the user property inspection of user B and initiates paging to VLR after receiving IAM.
(7) user B page response.
(8) MSC sends out SETUP message by BSS to user B, and user B acknowledges receipt calling.
(9) MSC starts channel assignment.
(10) after channel is set up and is finished, MSC will receive the ring-back message that MS sends, this moment, MSC judged whether the user has applied for the CRBT business, if do not apply for the then original ring-back tone of normal play, otherwise send initial address message to SN, request playing RBT, SN send ACM (Address Complete Message) message to MSC after finding corresponding ring-back tone.
(11) MSC sends CONNect Acknowledgement message to calling terminal after receiving ACM in FIN (CONNect Acknowledgement), exhales switch to send ACM message to rising, and the ring-back tone speech channel of continue SN and calling terminal.
(12) behind the Called Subscriber off-hook, MS sends connection message to MSC, and MSC returns and exhaled MS to reply concurrent receiveing the response (ANC) to the calling subscriber, sends RLG to SN and calls out release signaling, and disconnect the ring-back tone speech channel.
So far finish mobile terminated and play the whole speech channel handshaking procedure of customizable ring-back tone.
For supporting gorgeous bell business, this scheme need be carried out corresponding upgrading to legacy network, makes it support this supplementary service.Need each operator at first to formulate standard, then this standard is issued each main equipment manufacturer, main equipment manufacturer makes amendment to switch according to this standard, and switch can have the CRBT equipment supplier to carry out this business after revising and finishing.
The CRBT system of the scheme of taking out stitches takes out stitches after finishing the gorgeous color ring-back tone of broadcast, is not connected in series whole communication process, and its power system capacity is 14 times of polyphone speech channel solution, has saved the PCM voice resource greatly.
But this scheme business provides the time oversize.This scheme need be done corresponding modify to the program of MSC, needs the cooperation of switch producer, needs the long period can open Ring Back Tone service.Switch manufacturer makes amendment to switch according to this standard and needs and the test needs time, and last color ring systems manufacturer and switching system manufacturer cooperate and could may carry out Ring Back Tone service.
Cost is big.With this scheme realize Ring Back Tone service need operator for switch manufacturer pays a large sum of MSC update cost.
The difficulty of commencing business is big.Need MSC manufacturer and CRBT provider to do many cooperations Ring Back Tone service can be provided.
Above-mentioned two kinds of schemes from last surface analysis as can be seen, realize the individual audible ringing business, traditional solution is except will increasing the personalized ring back tone service platform, also need to revise Telecommunication network equipment software (MSC, HLR or PSTN switch etc.) and the call flow of telecommunications network is made certain modification, and the workload of revising Telecommunication network equipment software is very huge since the supplier of Chinese telecommunications network equipment a lot (CDMA: Huawei, in emerging, Shanghai Bell, Lucent, NORTEL, Ericsson; GSM: Huawei, in emerging, Datang, Shanghai Bell, Ericsson, Nokia, NORTEL, Siemens, Lucent), the whole network to support personalized ring back tone service, this just relates to a large amount of modifications and transfers survey work, not only requires great effort but also time-consuming.
Summary of the invention

The present invention also provides a kind of implementation method that produces the communication service of Customized Ring Back Tone, in fixed-line telephone network, is based on two ring technology, in mobile telephone network, is based on customer group and points out the FA technology to realize.After adopting two ring technology or FA technology, caller can calledly make a call simultaneously to two, and selects at first that the called subscriber of off-hook converses.
Be to support the gorgeous color audible ringing tone service of CRBT, need MSC and HLR in the cdma network to support the FA business since international standard and national sector standard all stipulated should business, so the main equipment supplier should provide this function.Based on the solution of FA, do not need to revise MSC and HLR program.
In this scheme, if user applies Ring Back Tone service, then in HLR, the FA business is set for this user, and the number corresponding with this user that is provided with in the CRBT database be made as same FA group, CRBT connects GMSC with the PCM link, other MSC in the service area is by signalling point address visit CRBT, be provided with and apply for color ring user B B ' number one to one in the CRBT system database, B ' number can be defined as non-moving number, then B ' set of numbers only needs a signalling point address to get final product in network in the CRBT system, can need address bit long by the number of users decision as required, only need other MSC or HLR to recognize non-moving number, then go to local GMSC, GMSC then will go to CRBT with the call path of the B ' that shakes according to the office direction of CRBT, because MSC calls out B and B ' simultaneously, in call link B ': CRBT receives the IAM that MSC sends, and ACM should reply to MSC at once in system; An other link: MSC sends IAM to MSC/VLR, and MSC/VLR needs calling user B, and response back MSC/VLR can send ACM message.According to FA mechanism: the link of preferential playing RBT will mask other one and jump link, answer signal is replied to MSC after receiving calling immediately by the CRBT system, preferential called MS C replys, the called B of CRBT system plays is the ring-back tone of calling subscriber A customization, after MSC receives called B off hook signal, again B ' link among the CRBT is taken out stitches A, B normal talking.
The concrete call flow of this programme is as follows:
When calling subscriber A calls out called subscriber B;
(1) caller MSC will be by the Locreq order to HLR, the address information of inquiring user B and the usefulness of B
The family information parameter;
(2)ROUTREQ【B,LegInfoB】
(3)Routreq【TLDN?B】
(4) HLR returns locreq[TLDN B, B ' to MSC] signal, wherein B ' is non-moving number;
(5) call out B:5, MSC and send the IAM signal to MSC/VLR;
6, MSC/VLR paging B;
7, page response;
8、ACM;
Call out B ': 5 ', MSC sends out IAM information to B ';
6’、ACM;
7 ', [this moment, TLDN B still was in paging state to ring-back tone, did not return ACM
Therefore signal is play the ring-back tone of SN, and SN broadcasts according to called B ' and calling number
Put the different ring-back tones that the party B-subscriber is provided with according to different callers];
(6) MSC receives ANC or the ANN signal [off-hook] that called MS C sends
(7) 8 ', MSC takes out stitches to B ';
9 ', release guard signal [RLG];
(8) A, B normal talking;
(9) then CRBT is to the customization ring-back of user A loop play certain hour, and recirculation is play one section User Status voice ring-back tone and taken out stitches up to caller MSC.
Situation during called subscriber's different conditions:
(1) when the called subscriber shuts down Power off,
When if the called subscriber does not apply for the note secretarial service, it is Inactive that HLR sends AccessDenied Reason to caller MSC, CRBT gives the customization ring-back of user A loop play certain hour, and recirculation is play one section User Status voice ring-back tone and taken out stitches up to caller MSC;
When if the called subscriber has applied for the note secretarial service, can hear that the called subscriber is the gorgeous color ring-back tone that the calling subscriber customizes.
(2) as called subscriber busy busy,
Situation one, ordinary circumstance, User Status was that Busy:HLR sends Access Denied Reason (Busy) to MSC when system carried out RoutingRequest, then CRBT gives the customization ring-back of user A loop play certain hour, and recirculation is play one section User Status voice ring-back tone and taken out stitches up to caller MSC;
Situation two, User Status was Busy when system carried out IAI
When confirming as the Busy state behind the IAI, send the called subscriber under the situation of the Release message comprise Reason code or call progress message, according to this scheme, the user can mention the called calling customized gorgeous color ring-back tone that is, according to the difference of system, may this kind situation not take place reality yet.
(3) as called subscriber's no response No Answer
When the called subscriber sends Release message, if comprise Reason code or send call progress message, CRBT gives the customization ring-back of user A loop play certain hour, one section User Status voice is play in recirculation, according to system's difference, if called MS C returns non-ACM message, then the calling subscriber takes out stitches after hearing normal recording prompting at last.If called MS C returns ACM message, then the calling subscriber can't hear the recording prompting of MSC system, and MSC takes out stitches up to caller.
(4) as called subscriber NPR, i.e. No Paging Response,
Situation one, in when, in China NPR taking place at present, behind the timer expired of appointment, reply ACM, after send the recording prompting again, in this case, it is calling customized CRBT that caller can be heard called, but can't hear voice suggestion, perhaps CRBT gives the customization ring-back of calling subscriber's loop play certain hour, and recirculation is play one section User Status voice ring-back tone and taken out stitches up to caller MSC;
Situation two, when NPR takes place for some switches at present, behind the timer expired of appointment, reply other signalings of non-ACM, then playback prompting again, in this case, caller can be heard the called calling customized CRBT that is, can also hear voice suggestion.
Based on the FA solution can be G network users, fixed-line subscriber, C net user and can support the C network users of FA business to play ring-back outside the province inside the province to caller, and the MSC/VLR that caller is served need support the FA business that the Ring Back Tone service based on this scheme can be provided.Call out for the C network users that can not support the professional MSC of FA outside the province, according to the FA design, the form of supporting the professional MSC of FA is arranged in the HLR, HLR only returns the called subscriber for caller MSC, is normal call, and Ring Back Tone service is not provided.
When the user roams, owing to adopted the polyphonic ringtone playing mechanism of Routing Digits, the broadcast of CRBT will be finished by the gorgeous color audible ringing tone system SN of user ascription area, and comprise step: the gorgeous color audible ringing tone system of user ascription area obtains user roaming state information; Gorgeous color audible ringing tone system increases user's information and individual audible ringing sound data in the user roaming place; Roaming data before the gorgeous color audible ringing tone system deletion user of ownership place; The current roaming state of change user; At user roaming place playing RBT.
Technological merit based on the FA solution:
(1) saves relay resource, save 14 times PCM relay resource with respect to speech channel polyphone scheme [intelligent network scheme and isolated node scheme].
(2) safe, owing in call treatment, adopt parallel mode fully,, do not influence call completing rate even the CRBT system goes wrong yet.
(3) do not influence other business: as call transfer service, caller identification business and intelligent network business etc.
(4) requirement to network element meets national standard, does not need MSC and HLR to do extra cooperation.
(5) can commence business fast, be a kind of brand-new CRBT solution, and the solution logic is simply workable.
(6) effectively protect original investment.The FA business is that international standard and industry standard are all stipulated benchmark service is provided, and can make full use of this business platform and carry out Ring Back Tone service, realizes the new business growth point.
Adopt this scheme not influence the normal now note secretary platform that uses of CHINAUNICOM, be call forwarding to 198, the CFB that calls forwarding on busy, no response/shutdown CFNA, call forwarding function, Call Forwarding Unconditional CFU, and can both hear the ring-back tone that called subscriber B or C customize for caller A.In addition, do not influence other supplementary services: discern limit service, fetch voice information service, MWN business and intelligent network business etc. as calling number identification display business, third-party call business, call transfer service, implicit Call Forwarding services, call waiting, calling number yet.
