The present invention is a kind of implementation method of Coloring Ring Back Tone, this method is the signatory Ring Back Tone service of calling subscriber, and the needs according to the calling subscriber customize corresponding CRBT, when this calling subscriber who has contracted Ring Back Tone service calls out the called subscriber, polyphonic ringtone playing equipment is play the CRBT that it customizes in advance for this calling subscriber, thereby satisfies calling subscriber's personal needs.

Describe the present invention below in conjunction with accompanying drawing.

Referring to Fig. 1, realize that the present invention needs following steps:

Step 101:, this caller is signed up as the calling RBT service user by revising calling subscriber's configuration data;

Step 102: the calling subscriber of signatory calling RBT service makes a call, and the caller switch triggers calling RBT service according to amended configuration data;

Step 103: set up the connection between caller switch and called switch and caller switch and the color ring systems;

Step 104: color ring systems passes through the caller switch set up and the connection between the color ring systems, plays the CRBT that this calling subscriber customizes in advance to the calling subscriber, realizes calling RBT service.

Wherein, in the present invention, after step 104 coloring ring back tone playing, also can further carry out following steps:

Step 105: called subscriber's off-hook is replied, and color ring systems stops the coloring ring back tone playing to the calling subscriber;

Step 106: caller switch that calling subscriber and called subscriber's utilization are set up and the connection between the called switch, realize voice communication; And the connection of being set up between release caller switch and the color ring systems;

Step 107: calling subscriber or called subscriber's on-hook, discharge the connection between caller switch and the called switch, finish whole voice communication flow process.

Wherein, in an embodiment of the present invention, be example with the mobile communication system, then step 101～step 102 can realize in the following way:

At first, revise the calling subscriber's CAMEL-Subscription-Information in the attaching position register (HLR) that is kept at calling subscriber's ownership, this calling subscriber is signed up as the calling RBT service user;

Then, in described calling RBT service user position update process,, in the caller switch, insert calling RBT service and trigger sign indicating number according to amended calling subscriber's CAMEL-Subscription-Information among the described HLR, the caller switch triggers sign indicating number according to calling RBT service, triggers calling RBT service.

In another embodiment of the present invention, be example with the fixed network system, then step 101～step 102 can realize in the following way:

In calling subscriber's fixed switch, Subscriber Number according to the calling subscriber that will be signed up as Ring Back Tone service, the calling subscriber's data that are configured in this fixed switch for this calling subscriber increase corresponding calling RBT service data, thereby this calling subscriber is signed up as the calling RBT service user, when this user calls out as the calling subscriber, this calling subscriber's caller fixed switch is according to the user data in the inquiry of the calling number in the calling out switch, and according to the calling RBT service data-triggered calling RBT service that is increased in these data.

Because in implementation procedure of the present invention, when adopting fixed network with mobile radio communication only is that triggering mode is different, and the step that triggers back specific implementation calling RBT service is identical, therefore, in following examples, all be with the mobile radio communication example present invention is described, the specific implementation and the mobile radio communication of fixed communication network are similar.

In concrete the application, can carry out in different ways for the signatory of CRBT service provided to the calling party user, corresponding, the triggering mode of calling RBT service is also different thereupon, below respectively in conjunction with different triggering modes, and with the mobile communication is example, and the specific implementation of above-mentioned steps is illustrated:

(1) adopt the mode of Caller Category, caller SS-CODE or expansion cell to trigger calling RBT service:

Because in agreement, Caller Category can have 254 kinds, and have a fairly large number of class of subscriber because reservation is used and is not used in the agreement at present, therefore, can use the Caller Category of these reservations to represent that the calling subscriber is the calling RBT service user.Thus, only need in the HLR of calling subscriber's ownership, in this calling subscriber's CAMEL-Subscription-Information, increase, can realize this calling subscriber is signed up as the calling RBT service user in order to represent the Caller Category of this calling subscriber for the calling RBT service user.

In addition, in presently used communication protocol, for operator provides can self-defining Supplementary Service Code SS_CODE, this SS_CODE comprises plmn_specificSS1～plmn_specificSS15, thus, in the present invention, can also utilize certain service code in the above-mentioned operator PLMN Specific Supplementary Services sign indicating number to identify the calling subscriber and be the calling RBT service user, and be embodied as the signatory calling RBT service of calling subscriber, be specially: in the HLR of calling subscriber's ownership, in this calling subscriber's CAMEL-Subscription-Information, increase and be used to represent the Supplementary Service Code plmn_specificSSX of this calling subscriber for the calling RBT service user, thereby realize this calling subscriber is signed up as the calling RBT service user, wherein, X is a natural number arbitrarily in 0～15, and this X can select according to the needs of operator.

In addition, also can adopt the mode of expansion cell to be embodied as the signatory calling RBT service of calling subscriber, in this mode, in the HLR of this calling subscriber's ownership, CAMEL-Subscription-Information increase corresponding business indication for this calling subscriber, and should business indicate corresponding and the corresponding expansion cell of calling RBT service, and realize in this way this calling subscriber is signed up as the calling RBT service user.When the calling subscriber carries out the position renewal, HLR can indicate according to the business in this calling subscriber's CAMEL-Subscription-Information, to expand cell accordingly and send to caller MSC as calling RBT service triggering sign indicating number in inserting the user data process, caller MSC carries out the triggering of calling RBT service according to this expansion cell.

Because the above-mentioned three kinds of modes of employing trigger calling RBT service and realize that the flow process of Ring Back Tone service is basic identical, therefore, below, to adopt the SS-CODE mode to be signed up as example, the idiographic flow of realizing calling RBT service is illustrated,, specifically may further comprise the steps referring to Fig. 2:

Step 201: calling mobile exchanging center (MSC) sends the position to the HLR of calling subscriber's ownership and upgrades (MAP_Update_Location) message, and request is carried out the position and upgraded;

Step 202: described HLR returns calling RBT service to caller MSC and triggers sign indicating number by inserting user data (MAP_Insert_Subscriber_Data) message; Wherein, in the present embodiment, because adopting the SS-CODE mode contracts on the HLR of calling subscriber's ownership, therefore, the calling RBT service that HLR returns to caller MSC triggers sign indicating number and is Supplementary Service Code plmn_specificSSX, in other embodiment of the present invention, when adopting Caller Category to contract, then HLR is Caller Category to the calling RBT service triggering sign indicating number that caller MSC returns; When adopting the expansion cell to contract, then HLR is corresponding expansion cell to the calling RBT service triggering sign indicating number that caller MSC returns, caller MSC is according to the Caller Category of receiving or expand the triggering that cell is realized follow-up calling RBT service, and the description in the realization flow and the follow-up embodiment of the invention is in full accord;

Step 203 step 204: caller MSC sends routing iinformation (SRI) message to described HLR, acquisition request called subscriber's roaming number, after this HLR receives this message, called subscriber's roaming number is returned to caller MSC by SRI response message (SRI_ACK);

Step 205: caller MSC sends initial address message (IAM) according to called subscriber's roaming number of receiving to called MS C, sets up being connected between caller MSC and the called MS C;

Step 206: called MS C sends Address Complete Message (ACM) to caller MSC, called subscriber's current state is returned to caller MSC, and notice caller MSC sets up successfully with being connected of called MS C;

Step 207: caller MSC triggers calling RBT service according to the Supplementary Service Code plmn_specificSSX that receives in the above-mentioned insertion user data process, and making up called number is the IAM information and sending of this form of Ring Back Tone service prefix+rear subscriber number; Wherein, the calling number of constructed IAM message is former calling number, called number then is modified to the form of Ring Back Tone service prefix+rear subscriber number after triggering calling RBT service, can obtain the color ring systems that this calling subscriber belongs to according to this called number analysis so that call out the intermediate office that carries out in the process, and be forwarded on this color ring systems this IAM message is corresponding, in addition, in this IAM message, also carry original called party number; Wherein, in embodiments of the present invention, because what adopt is that the SS-CODE mode is carried out the Ring Back Tone service triggering, therefore, caller MSC triggers calling RBT service according to inserting the Supplementary Service Code plmn_specificSSX that obtains in the user data process, in other embodiment of the present invention, if adopt Caller Category to trigger, then caller MSC correspondingly triggers calling RBT service according to inserting the Caller Category that obtains in the user data process, if adopt the expansion cell to trigger, then caller MSC correspondingly triggers calling RBT service according to inserting the expansion cell that obtains in the user data process, follow-up flow process and the follow-up flow process described in the embodiment of the invention after the triggering are in full accord, do not influence realization of the present invention;

Step 208: color ring systems returns ACM message to caller MSC after receiving the IAM message that caller MSC sends, and being connected between notice caller MSC and the color ring systems set up successfully;

Step 209: color ring systems is searched and is obtained the customized in advance CRBT of this calling subscriber according to the calling number of carrying in this IAM message, and plays this CRBT by the ANM that sends to caller MSC to caller MSC;

Wherein, in step as mentioned above, caller MSC is after receiving called subscriber's time of day by step 206, and just execution in step 207 triggers calling RBT service, thereby realizes calling RBT service in the mode of serial; In other embodiment of the present invention, also can executed in parallel step 206 and step 207～step 209, thus realize calling RBT service in parallel mode, do not influence realization of the present invention;

Till step 209, realized Ring Back Tone service, consider the integrality of voice communication course, in concrete the application, the embodiment of the invention also further may further comprise the steps:

Step 210: called subscriber's off-hook is replied, and called MS C sends ANM to caller MSC, is communicated with the speech channel between caller MSC and the called MS C;

Step 211～step 212: caller MSC sends to color ring systems and discharges (REL) message, request discharges being connected between caller MSC and the color ring systems, after color ring systems is received this message, stop coloring ring back tone playing to caller MSC, and, return release to caller MSC and finish (RLC) message, discharge the connection of being set up between caller MSC and the color ring systems;

Wherein, in embodiments of the present invention, step 210 and step 211～step 212 order is carried out, and in other embodiment of the present invention, execution in step 210 and step 211～step 212 simultaneously do not influence realization of the present invention yet;

Step 213: calling subscriber and called subscriber utilize the speech channel of being set up between caller MSC and the called MS C, realize voice communication;

Step 214: calling subscriber's on-hook, caller MSC sends REL message to called MS C, and request discharges being connected between caller MSC and the called MS C;

Step 215: called MS C returns RLC message to caller MSC, discharges being connected between caller MSC and the called MS C;

Wherein, in embodiments of the present invention, be that example describes only with calling subscriber's on-hook, under the situation of called subscriber's on-hook, then called MS C sends REL message to caller MSC, caller MSC returns RLC message to called MS C, thereby discharges the connection between caller MSC and the called MS C, does not influence realization of the present invention.

(2) adopt aptitude manner to trigger calling RBT service:

When adopting aptitude manner to trigger calling RBT service, in the HLR of calling subscriber's ownership, CAMEL-Subscription-Information increase calling terminal camel user profile (OCSI) subscription data for this calling subscriber, this OCSI subscription data is in order to represent that this calling subscriber is the calling RBT service user, use calling RBT service user corresponding service key, this calling subscriber is signed up as the calling RBT service user thereby finish; Finish this signatory after, referring to Fig. 3, realize that calling RBT service may further comprise the steps:

Step 301: caller MSC sends the position to the HLR of calling subscriber's ownership and upgrades (MAP_Update_Location) message, and request is carried out the position and upgraded;

Step 302: described HLR returns the OCSI subscription data that triggers sign indicating number as calling RBT service by inserting user data (MAP_Insert_Subscriber_Data) message to caller MSC; Wherein, the address that comprises caller MSC corresponding service control point (SCP) in this OCSI subscription data at least;

Step 303～step 304: caller MSC is according to the SCP address in the OCSI subscription data, send initial DP (IDP) message to this SCP, carry in this IDP message and the corresponding service key of calling RBT service, SPC is according to the service key in this IDP message, judge that obtaining this calling subscriber is the calling RBT service user, called number is revised as the form of first Ring Back Tone service prefix+original called party number, and should be handed down to caller MSC by amended called number by connecting (CONNECT) message; Wherein, the described first Ring Back Tone service prefix triggers sign indicating number as calling RBT service, is used to make caller MSC to trigger calling RBT service according to this prefix;

Step 305: caller MSC sends IAM message according to called number to called MS C;

Step 306: called MS C returns ACM message to caller MSC, and called subscriber's current state is returned to caller MSC, and notice caller MSC set up successfully with being connected of called MS C;

Step 307: caller MSC triggers calling RBT service according to the first Ring Back Tone service prefix of being returned in the CONNECT message, and making up called number is the IAM information and sending of second this form of Ring Back Tone service prefix+rear subscriber number; Wherein, the calling number of constructed IAM message is former calling number, called number then is modified to the form of second Ring Back Tone service prefix+rear subscriber number after triggering calling RBT service, can obtain the color ring systems that this calling subscriber belongs to according to this called number analysis so that call out the intermediate office that carries out in the process, and be forwarded on this color ring systems this IAM message is corresponding, in addition, in this IAM message, also carry original called party number;

Step 308: color ring systems returns ACM message to caller MSC after receiving the IAM message that caller MSC sends, and being connected between notice caller MSC and the color ring systems set up successfully;

Step 309: color ring systems is searched and is obtained the customized in advance CRBT of this calling subscriber according to the calling number of carrying in this IAM message, and plays this CRBT by the ANM that sends to caller MSC to caller MSC;

Wherein, in step as mentioned above, caller MSC is after receiving called subscriber's time of day by step 306, and just execution in step 307 triggers calling RBT service, thereby realizes calling RBT service in the mode of serial; In other embodiment of the present invention, also can executed in parallel step 306 and step 307～step 309, thus realize calling RBT service in parallel mode, do not influence realization of the present invention;

1, called RBT service and calling RBT service all trigger at caller MSC:

In the case, in case carry out after the operation that triggers calling RBT service in the above-mentioned steps 207 or 307, caller MSC preserves the current calling RBT service that triggered in the Ring Back Tone service trigger recording, the specific implementation of this record can be rearmounted corresponding sign on calling number, with identify this calling number correspondence triggered calling RBT service, in the case, this caller MSC is before triggering called RBT service, at first judge the current calling RBT service that whether triggered according to its Ring Back Tone service trigger recording, if, then no longer carry out the step that triggers called RBT service, otherwise, trigger called RBT service and carry out corresponding flow process.

2, called RBT service and calling RBT service trigger at different MS C respectively:

In the case, caller MSC judges whether the state of indication called subscriber in the backward signalling is idle, if, the CRBT that sets of caller switch shielding called subscriber then, with the connection of caller forward direction directly and color ring systems link up, the called connection of getting along well, thereby the CRBT of setting to calling subscriber's playing and calling user only, simultaneously, with the back to connection and caller MSC keep apart, wherein, described back is to being connected to and being connected of the next switch of call proceeding.

In voice communication course, also situations such as connection failure and Call Waiting may appear, corresponding, need play failure prompt tone and Call Waiting prompt tone to the calling subscriber, in the case, caller MSC judges whether to receive failure announcement Indication message or Call Waiting Indication message, if, then stop the playing and calling CRBT, discharge being connected between caller MSC and the color ring systems, and play failure prompt tone or Call Waiting prompt tone to the calling subscriber.

In calling procedure, also Call Forwarding may appear, at this moment, trigger called RBT service or only play common ring-back tone for fear of follow-up called subscriber occurring, in the present invention, under the situation that forwarded calls takes place, color ring systems still continues the CRBT to caller MSC playing and calling order, unless subsequent voice calls connection failure or need carry out Call Waiting, Cai play failure prompt tone or Call Waiting prompt tone to caller MSC.

When adopting Intellight network mode to trigger called RBT service, if caller MSC carries out after the operation that triggers calling RBT service in the above-mentioned steps 207 or 307, caller SCP revises caller universal number or Caller Category, to represent that this calling subscriber has triggered calling RBT service, called SCP is according to amended caller universal number or Caller Category, judge and obtain the current calling RBT service that triggered, no longer trigger called RBT service, thereby avoid occurring calling RBT service and the conflicting problem of called RBT service;

When adopting the called triggering Ring Back Tone service of mode except that intelligent network, if caller MSC carries out after the operation that triggers calling RBT service in the above-mentioned steps 207 or 307, revise Caller Category, to represent that this calling subscriber has triggered calling RBT service, trigger switch or this amended Caller Category of miscellaneous equipment basis of called RBT service, judge and obtain the current calling RBT service that triggered, no longer trigger called RBT service, thereby avoid occurring calling RBT service and the conflicting problem of called RBT service.

In the present invention, can realize in the following way that color ring systems plays Comfort Noise Generation (CNG) to the calling subscriber:

1, color ring systems is according to calling number, to the fixing Comfort Noise Generation (CNG) of described calling subscriber play that this calling subscriber customizes in advance;

2, color ring systems is selected a Comfort Noise Generation (CNG) at random according to calling number from a plurality of Comfort Noise Generation (CNG)s that this calling subscriber customizes in advance, and plays to the calling subscriber;

3, color ring systems is play as described Comfort Noise Generation (CNG) common ring-back tone according to calling number to the calling subscriber;

4, color ring systems is determined the Comfort Noise Generation (CNG) of required broadcast according to calling number and called number, and plays to the calling subscriber.

In the above embodiment, all be to be that example describes with the MSC that is adopted in the mobile communication process, in other embodiment of the present invention, also can adopt fixed switch to realize the triggering and the specific implementation of called RBT service, do not influence realization of the present invention.
