Description

METHOD FOR SETTING COLORING RING BACK TONE

FIELD OF THE INVENTION

The present invention relates to a method for setting Coloring Ring Back Tone (CRBT), and particularly to, in a communication network, copying a CRBT subscribed by a called terminal and being played into a CRBT library for a calling terminal, as the CRBT to be only received by the called terminal when the called terminal calls the calling terminal, and/or setting a CRBT similar to or associated with the CRBT subscribed by the called terminal and being played into the CRBT library for the calling terminal, as the CRBT to be received by all other terminals that call the calling terminal or only received by the called terminal, wherein the CRBT may be an audio CRBT or a video CRBT.

BACKGROUND OF THE INVENTION

In recent years, personalized CRBTs are widely used in communications. With such technology, when a calling subscriber calls the mobile phone number of a called subscriber, he or she can hear a piece of euphonic music or a greeting, instead of the traditional ring back tone "du, du". Thus the calling process is relaxed and interesting, which is helpful to relieve the anxious mood of the calling subscriber when waiting for a connection.

Typically, the called subscriber for example can apply for the CRBT service by himself or herself in the service hall (e.g., service provider company, service provider store or other store, whether physical store or online store, other store at which CRBT service and/or software or the like can be obtained, and so on), and at the same time, select different CRBTs for different calling subscriber groups. But it will take the called subscriber's time, and is inconvenient for the called subscriber to change new CRBTs according to his or her preference or mood variation. Alternatively, the called subscriber can apply for the service and set a CRBT on a website that provides CRBT download. By comparison, this method makes great improvements in CRBT audition and change. But the called subscriber shall login the special website and spend time in auditioning many CRBTs to make a selection. Particularly, when the called subscriber cannot login the Internet, e.g., being on a trip, he or she will not set or update the CRBT.

l In actual life, when calling the called subscriber, the calling subscriber often hears a very fair-sounding or interesting CRBT subscribed by the called subscriber, and he or she will also want to subscribe such CRBT or the like as his or her own CRBT. At that time, if in the traditional way, the calling subscriber shall specially go to the service hall or login the website to subscribe the CRBT, he or she will not easily find the CRBT in many cases.

Or, there is a special relationship between the calling subscriber and the called subscriber, such as family, lover or close friend relationship. When the calling subscriber hears the CRBT subscribed by the called subscriber during the process of calling the called subscriber, in order to reflect their close relationship, he or she also wants to subscribe the same or similar CRBT specially for the called subscriber, so that the called subscriber will be aware of their close relationship through the heard CRBT when calling the calling subscriber.

Thus there is a need to be able conveniently to set for the calling subscriber, a CRBT of the called subscriber received by the calling subscriber, during a CRBT playing process, a communication process or after a call is ended.

SUMMARY OF THE INVENTION

The present invention is provided with respect to the above problems in the prior art. According to an aspect of the present invention, a method for setting a CRBT is provided so that a calling subscriber or a called subscriber can set the CRBT received when the calling subscriber calls the called subscriber, or a CRBT similar to or associated with the received CRBT, into a CRBT library for the calling subscriber, and preferably can set the CRBT to be received only by the called subscriber when the called subscriber calls the calling subscriber.

A first aspect of the invention provides a method for setting a Coloring Ring Back Tone (CRBT), including:

initiating a call to a called terminal and receiving a CRBT subscribed by the called terminal sent from a CRBT Service Center (CBC), by a calling terminal in a communication network;

during the process of playing the CRBT or the communication process or after the call is ended, authenticating the calling terminal by the communication network in response to a CRBT setting request message sent by the calling terminal or the called terminal actively or upon an inquiry from the communication network, so as to judge whether the calling terminal already activated a CRBT service;

if it is judged in the step of authenticating that the calling terminal has not activated a CRBT service, sending, by the communication network, a CRBT service activation message to the calling terminal to instruct the calling terminal to activate the CRBT service, and then activating, by the calling terminal, the CRBT service through a response to the CRBT service activation message, or sending, by the communication network, to the called terminal a message about activating the CRBT service for the calling terminal, and then activating, by the called terminal, the CRBT service for the calling terminal through a response to the message; and

if it is judged in the step of authenticating that the calling terminal already activated the CRBT service, or the CRBT service is activated for the calling terminal in the step of activating the CRBT service, instructing, by the communication network, the CBC to set a CRBT same as or similar to or associated with the CRBT received by the calling terminal into a CRBT library for the calling terminal.

A second aspect of the invention provides a method based on the first aspect, wherein the CRBT setting request message is a message sent, during the calling process, through pressing a specific key of the calling terminal or the called terminal, or operating on a specific menu of the calling terminal or the called terminal, or upon the setting of the calling terminal or the called terminal, and the message instructs to copy a CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and set the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

A third aspect of the invention provides a method based on the first aspect, wherein the CRBT setting request message is sent by the calling terminal or the called terminal responding to an inquiry message from the communication network after the call is ended, wherein the inquiry message prompts whether to set a CRBT same as or similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

A fourth aspect of the invention provides a method based on the third aspect, wherein the CRBT setting request message instructs to copy a CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and set the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

A fifth aspect of the invention provides a method based on the second or fourth aspect, wherein in the step of setting the CRBT, the CBC copies the CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and sets the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

A sixth aspect of the invention provides a method based on the third aspect, wherein the CRBT setting request message instructs to copy a CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

A seventh aspect of the invention provides a method based on the sixth aspect, wherein in the step of setting the CRBT, the CBC copies the CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

A eighth aspect of the invention provides a method based on the sixth aspect, wherein the CRBT setting request message further instructs to set the CRBT similar to or associated with that received by the calling terminal to be only received by the called terminal when the called terminal calls the calling terminal.

A ninth aspect of the invention provides a method based on the eighth aspect, wherein in the step of setting the CRBT, the CBC sets the CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal, and sets the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

A tenth aspect of the invention provides a method based on the first aspect, wherein in the step of setting the CRBT, the CBC sets a serial number of the CRBT same as similar to or associated with that received by the calling terminal to the CRBT library for the calling terminal.

An eleventh aspect of the invention provides a method based on the first aspect, wherein the step of authenticating is performed by the CBC.

A twelfth aspect of the invention provides a method based on the eleventh aspect, wherein the step of authenticating includes:

searching, by the CBC, in a database thereof based on the telephone number of the calling terminal, and if the telephone number of the calling terminal exists in the database, judging that the calling terminal already activated the CRBT service, otherwise judging that the calling terminal has not activated the CRBT service.

A thirteenth aspect of the invention provides a method based on any one of the preceding aspects, after the step of setting the CRBT, further including:

sending, by the CBC, a CRBT setting success message to the calling terminal or the called terminal.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Those and other aspects of the present invention will be clear in reference to the following descriptions and drawings. These descriptions and drawings specifically disclose some specific embodiments of the present invention to reflect certain ways for implementing the principle of the present invention. But it shall be appreciated that the scope of the present invention is not limited thereby. On the contrary, the present invention includes all changes, modifications and equivalents falling within the range of spirit and connotation of the accompanied claims.

Features described and/or illustrated with respect to an embodiment can be used in the same way or similar way in one or more other embodiments, and/or in combination with the features of other embodiment or replace the features of other embodiment.

To be emphasized, the terms "include/including" or "comprise/comprising" used in the present invention mean presence of the stated feature, integer, step or component, not excluding the presence or addition of one or more other features, integers, steps, components or a group thereof.

A mobile communication network is taken as an example to describe the embodiments of the present invention as follows. But it is appreciated to a person skilled in the art that, the CRBT service is not limited to the mobile communication network, and a fixed-line telephone network can also use the CRBT service, and thus the present invention also covers applications in the fixed-line telephone network. In addition, the CRBT is typically an audio CRBT, but a video CRBT can also be used for a visual telephone terminal. The setting applications of an audio CRBT and a video CRBT are both covered by the present invention. In the following descriptions, the CRBT may be either an audio CRBT or a video CRBT, unless otherwise specified.

First of all, the configuration of a part of a mobile communication network related to the present invention is described as follows in reference to Fig. 1.

The mobile communication network includes a calling mobile terminal MT1, a called mobile terminal MT2, a first mobile switching center MSC1 , a second mobile switching center MSC2, a CRBT service center CBC and a short message service center SMSC.

The CBC is configured to store and manage CRBT resources. The SMSC is configured to send information to MT1 and MT2.

Next, the first embodiment of the present invention is described in reference to flowchart 2000 of Fig. 2.

Firstly, in step S2010, MT1 initiates a call to MT2 via MSC1 and MSC2. Next, in step S2020, MTl receives a CRBT played by the CBC since MT2 already subscribed a CRBT service.

Next, in step S2030, during the process of playing the CRBT or during the subsequent communication process, if the calling subscriber likes the CRBT of the called subscriber, or considers the special relationship therebetween such as family, lover or close friend relationship, and hence wants to copy the CRBT of the called subscriber so that the called subscriber can hear the same CRBT when calling the calling subscriber, the calling subscriber for example can press a special key (e.g., "*" key) on MTl to send a CRBT copy request message, which contains the phone number of MTl, to instruct to copy the CRBT just heard by the calling subscriber into a CRBT library for MTl , and set the CRBT to be received only by MT2 when it calls MTl . Alternatively, in this step, the CRBT copy request message can be sent by operating on the menu of MTl . Alternatively, for example, MTl may automatically send the CRBT copy request message based on for example the settings in the contact list of MTl , in which, for example, the phone number of MT2 is set in a certain specific relationship such as family, lover or close friend relationship, and tracking of the CRBT of MT2 is set.

Next, in step S2040, MSC1 receives the CRBT copy request message sent by MTl , and forwards it to the CBC.

Next, in step S2050, after receiving the CRBT copy request message, the CBC authenticates MTl to judge whether MTl already activated the CRBT service. Specifically, the CBC can search the phone number of MTl in its database, and if the number is found, it means that MTl already activated the CRBT service, otherwise MTl has not activated the CRBT service. If the judgment result is "Yes", i.e., MTl already activated the CRBT service, the procedure will go to step S2080, and if the judgment result is "No", the procedure will go to step S2060.

In step S2060, the CBC sends a CRBT service activation message to MTl . Next, in step S2070, MT1 activates the CRBT service by responding to the CRBT service activation message sent by the CBC.

Next, in step S2080, the CBC stores a CRBT file into the CRBT library for MT1, for example, preferably associates the serial number of the CRBT file with the phone number of MT1, and sets the CRBT file to be received only by MT2.

Next, after the CRBT is copied, the CBC can send a CRBT copy success message to MT1 in step S2090.

In this embodiment, MT1 and MT2 may belong to the same MSC. In this case, the CRBT copying procedure is the same as the above procedure.

Thus, according to the embodiment, when calling the called subscriber, the calling subscriber can copy the CRBT of the called subscriber into the CRBT library for the calling subscriber himself or herself, and set the CRBT to be received only by the called subscriber. This saves the process that the calling subscriber specially auditions and selects the CRBT, and the CRBT synchronization makes two parties in communication feel amiable.

Next, the second embodiment of the present invention is described in reference to flowchart 3000 of Fig. 3. The second embodiment differs from the first embodiment mainly in that the CRBT copy request message is sent by the called subscriber, rather than by the calling subscriber.

Firstly, in step S3010, MT1 initiates a call to MT2 via MSC1 and MSC2.

Next, in step S3020, MT1 receives the CRBT played by the CBC since MT2 already subscribed a CRBT service.

Next, in step S3030, during the communication process, if the calling subscriber says that he or she likes the CRBT of the called subscriber, or the called subscriber considers the special relationship therebetween such as family, lover and close friend relationship, and hence wants to copy his or her CRBT to the calling subscriber so that the called subscriber can hear the same CRBT when calling the calling subscriber, the called subscriber for example can press a special key (e.g., "#" key) on MT2 to send a CRBT copy request message, which contains the phone number of MT1 , and instructs to copy the CRBT just heard by the calling subscriber into the CRBT library for MT1 , preferably associate the serial number of the CRBT with the phone number of MT1 , and set the CRBT to be received only by MT2 when it calls MT1. Alternatively, in this step, the CRBT copy request message may be sent by operating on the menu of MT2. Still alternatively, for example, MT2 may automatically send the CRBT copy request message during the process of playing the CRBT or during the communication process based on for example the settings in the contact list of MT2, in which, for example, the phone number of MT1 is set in a certain specific relationship such as family, lover or close friend relationship.

Next, in step S3040, MSC2 receives the CRBT copy request message sent by MT2, and forwards it to the CBC.

Next, in step S3050, after receiving the CRBT copy request message, the CBC authenticates MT1 to judge whether MT1 already activated the CRBT service. Specifically, the CBC can search the phone number of MT1 in its database, and if the number is found, it means that MT1 already activated the CRBT service, otherwise MT1 has not activated the CRBT service. If the judgment result is "Yes", i.e., MT1 already activated the CRBT service, the procedure will go to step S3080, and if the judgment result is "No", the procedure will go to step S3060.

In step S3060, the CBC sends a CRBT service activation message to MT1. Preferably, the CRBT service activation message simultaneously indicates that MT2 will copy the CRBT just played for MT1.

Next, in step S3070, MT1 activates the CRBT service by responding to the CRBT service activation message sent by the CBC. Next, in step S3080, the CBC stores a CRBT file into the CRBT library for MTl , preferably associates the serial number of the CRBT file with the phone number of MTl , and preferably further sets the CRBT file to be received only by MT2.

Next, after the CRBT is copied, the CBC can send a CRBT copy success message to MTl and MT2 in step S3090.

In this embodiment, MTl and MT2 may belong to the same MSC. In such case, the CRBT copying procedure is the same as the above procedure.

Thus, according to the embodiment, when the calling subscriber calls the called subscriber, the called subscriber can copy the CRBT of the called subscriber into the CRBT library for the calling subscriber, based on the calling subscriber's evaluation on the just heard CRBT or the relationship between the two parties, and preferably further set the CRBT to be received only by the called subscriber. This saves the process that the calling subscriber specially auditions and selects a CRBT, and the CRBT synchronization makes two parties in communication feel amiable.

In this embodiment, it is defaulted that the called subscriber is chargeable. Alternatively, the calling subscriber may also be chargeable. For example, before the CRBT copy is completed, a CRBT copy confirming and charging message can be sent to MTl and/or MT2 by the CBC to require a corresponding response, so as to determine which party will finally pay for the CRBT copy.

The flowchart 3000' in Fig. 4 illustrates a modification of the second embodiment. The modification differs from the second embodiment in that steps S3060 and S3070 are replaced with steps S3060' and S3070', and the called subscriber activates the CRBT service for the calling subscriber. Specifically, in step S3060', the CBC sends a message to MT2 to indicate that MTl still does not activate the CRBT service and cannot copy the CRBT, and require the MT2 to make a response to activate the CRBT service for MTl . Next, in step S3070', MT2 responds to the above message and requests the CBC to activate the CRBT service for MTl . Then, the CBC activates the CRBT service for MTl . Preferably, after the CBC activates the CRBT service for MTl , it can also send a message to MTl and/or MT2 to indicate that MT2 has successfully activated the CRBT service for MTl . Subsequently, steps S3080 and S3090 are executed to copy the CRBT for MTl and send a CRBT copy success message. This is especially suitable for the case that during a communication procedure, the called subscriber knows that the calling subscriber likes the CRBT just played, and hopes the called subscriber to activate the CRBT service and copy the CRBT for him/her. Alternatively, in step 3070', the following operations may be added: after receiving the response message from MT2, the CBC can send MTl a message again to require MTl to confirm whether or not to allow MT2 to activate the CRBT service for MTl . If MTl responds to confirm that MT2 is allowed to activate the CRBT service for MTl, the CBC will activate the CRBT service for MTl and continue to perform the subsequent operations, otherwise the subsequent operations will not be performed and the CBC sends a message to MT2 to indicate that MTl does not hope to activate the CRBT service, and thus the CRBT copy operation cannot be performed.

According to the modification, the called subscriber can activate the CRBT service for the calling subscriber so as to facilitate copying CRBT. In the modification, the called subscriber is chargeable. Alternatively, the calling subscriber may also be chargeable. For example, before the CRBT copy is completed, a CRBT copy confirming and charging message can be sent to MTl and/or MT2 by the CBC to require a corresponding response, so as to determine which party will finally pay for the CRBT copy.

Next, the third embodiment of the present invention is described in reference to flowchart 5000 of Fig. 5. The third embodiment differs from the previous embodiments in that during or after the calling process, the CBC sends MTl an inquiry message to request MTl to set a CRBT same as or similar to that of MT2 heard in the calling process. The detailed process is as follows.

Firstly, in step S5010, MTl initiates a call to MT2 via MSC1 and MSC2.

Next, in step S5020, MTl receives the CRBT played by the CBC since MT2 already subscribed the CRBT service. Next, in step S5030, during or after the calling process, the CBC sends MTl a message to inquiry whether the calling subscriber hopes to set a CRBT same as that of the called subscriber just heard, or a similar or associated CRBT. The inquiry message may include various response options, such as "respond with "1 *" to copy the same CRBT that is only received by the called subscriber", "respond with "2*" to set any other CRBT of the same style", "respond with "3*" to set any other CRBT of the same artist", etc. To be noted, the codes and their meanings listed herein are just examples.

Next, in step S5040, MTl makes a response to the inquiry message. For example, "1 *" is responded to indicate that MTl wants to copy a CRBT same as that of the called subscriber and to be only received by the called subscriber when the called subscriber calls the calling subscriber.

Next, in step S5050, after receiving the response message from MTl , the CBC authenticates MTl to judge whether MTl already activated the CRBT service. Specifically, the CBC can search the phone number of MTl in its database, and if the number is found, it means that MTl already activated the CRBT service, otherwise MTl has not activated the CRBT service. If the judgment result is "Yes", i.e., MTl already activated the CRBT service, the procedure will go to step S5080, and if the judgment result is "No", the procedure will go to step S5060.

In step S5060, the CBC sends a CRBT service activation message to MTl .

Next, in step S5070, MTl activates the CRBT service by responding to the CRBT service activation message sent by the CBC.

Next, in step S5080, the CBC sets a CRBT based on the response message from MTl . For example, as mentioned above, when MTl responds with code "1 *", the CBC stores a CRBT file same as that just heard by the calling subscriber into the CRBT library for MTl , preferably associates the serial number of the CRBT file with the phone number of MTl , and sets the CRBT file to be received only by MT2. When MTl responds with other options, the CBC can perform corresponding CRBT settings. For example, when MTl responds with code "2*", the CBC can select from the CRBT library a piece of CRBT having the style same as that received by MTl (e.g., Rap style), and set the selected CRBT into the CRBT library for MTl . In addition, the CBC can be further set so that, for example, when MTl responds with code "2* !", the CBC may, after setting for MTl a CRBT having the style same as that received by MTl, further set the CRBT to be received only by MT2. Alternatively, after selecting the CRBT, the CBC can play the CRBT for MTl, and sets the CRBT for MTl after MTl responds with a message to accept the CRBT; if MTl responds with a message hoping to audition other CRBTs, the CBC continues to select another CRBT of the same style, and executes operations of audition and setting same as those described previously.

Next, after the CRBT is copied, the CBC can send a CRBT copy success message to MTl in step 5090.

In this embodiment, MTl and MT2 may belong to the same MSC. In this case, the CRBT copying process is same as the above process.

Thus, according to the embodiment, after calling the called subscriber, the calling subscriber can subsequently determine whether to copy a CRBT same as, similar to, or associated with the CRBT just heard based on the message from the CBC, thereby saving/facilitating the process of auditioning and selecting a CRBT by the calling subscriber.

Flowchart 5000' in Fig. 6 illustrates a modification of the third embodiment. The modification differs from the third embodiment in that the CBC sends an inquiry message to MT2. Specifically, in step 5030', during or after the calling process, the CBC sends a message to MT2 to inquiry whether the called subscriber wants to set for the calling subscriber a CRBT same as, similar to or associated with that of the called subscriber just heard by the calling subscriber. The inquiry message may include various response options, such as "responding with 1# to copy, for the calling subscriber, the same CRBT that is only received by the called subscriber", "responding with 2# to set any other CRBT of the same style for the calling subscriber", "responding with 3# to set any other CRBT of the same artist for the calling subscriber", etc. To be noted, the codes and their meanings listed herein are just examples.

Next, in step 5040', MT2 makes a response to the inquiry message. For example, "1#" is responded to indicate that MT2 wants to copy for the calling subscriber, a CRBT which is same as that of MT2 and to be only received by the called subscriber when the called subscriber calls the calling subscriber. When MT2 responds with other options, the CBC can perform corresponding CRBT settings. For example, when MT2 responds with code "2#", the CBC can select from the CRBT library a piece of CRBT having the style same as that received by MTl (e.g., Rap style), and set the selected CRBT into the CRBT library for MTl . In addition, the CBC can be further set so that, for example, when MT2 responds with code "2#!", the CBC may, after setting for MTl a CRBT having the style same as that received by MTl , further set the CRBT to be received only by MT2. Alternatively, after selecting the CRBT, the CBC can play the CRBT for MTl , and sets the CRBT for MTl after MTl responds with a message to accept the CRBT; if MTl responds with a message to indicate audition of other CRBTs, the CBC continues to select a CRBT of the same style, and executes operations of audition and setting same as those described previously.

The subsequent process is similar to that in the third embodiment, and herein is not described in details.

Thus, according to the embodiment, after the calling subscriber calls the called subscriber, the called subscriber can subsequently determine whether to copy for the calling subscriber, a CRBT same as, similar to, or associated with the CRBT just heard by the calling subscriber based on the inquiry message from the CBC and an evaluation from the calling subscriber during the communication process on the CRBT just heard, thereby saving/facilitating the process of auditioning and selecting CRBT by the calling subscriber.

Alternatively, as described in steps 3060' and 3070' in Fig. 4, the CRBT service can also be activated for MTl by MT2 in that embodiment, and it is not described herein in details. In the above embodiments described in reference to Figs. 5 and 6, relevant information of a CRBT being played, such as "track name" and "artist", can be obtained by means of the TrackID™ technology of Sony Ericsson, in order to select a CRBT similar to or associated with the played CRBT. In addition, MTl for example may also acquire information about the received CRBT by using the embedded TrackID™ application, in order to select and set a CRBT. The TrackID™ technology is a known application and herein is not described in details.

In the above embodiments, whether MTl already activated the CRBT service is judged by the CBC. Alternatively, it may be possible to judge whether MTl already activated the CRBT service by MSC1, to which MTl belongs, detecting a Home Location Register (HLR) of MTl . This is well known by a person skilled in the art, and herein is not described in details.

Although the present invention is only illustrated with the above preferred embodiments, a person skilled in the art can easily make various changes and modifications based on the disclosure herein without departing from the invention scope defined by the accompanied claims. The description of the above embodiments is just exemplary, and will not limit the invention defined by the accompanied claims and their equivalents.

It will be appreciated that various portions of the present invention can be implemented in hardware, software, firmware, or a combination thereof. In the described embodiments, a number of the steps or methods may be implemented in software or firmware that is stored in a memory and executed by a suitable instruction execution system.

Claims

CLAIMS What is claimed is:

1. A method for setting a Coloring Ring Back Tone (CRBT), comprising the steps of: initiating a call to a called terminal and receiving a CRBT subscribed by the called terminal sent from a CRBT Service Center (CBC), by a calling terminal in a communication network;

2. The method according to claim 1, wherein the CRBT setting request message is a message sent, during the calling process, through pressing a specific key of the calling terminal or the called terminal, or operating on a specific menu of the calling terminal or the called terminal, or upon the setting of the calling terminal or the called terminal, and the message instructs to copy a CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and set the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

3. The method according to any one of the preceding claims, wherein the CRBT setting request message is sent by the calling terminal or the called terminal responding to an inquiry message from the communication network after the call is ended, wherein the inquiry message prompts whether to set a CRBT same as or similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

4. The method according to any one of the preceding claims, wherein the CRBT setting request message instructs to copy a CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and set the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

5. The method according to any one of the preceding claims, wherein in the step of setting the CRBT, the CBC copies the CRBT same as that received by the calling terminal into the CRBT library for the calling terminal, and sets the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

6. The method according to any one of the preceding claims, wherein the CRBT setting request message instructs to copy a CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

7. The method according to any one of the preceding claims, wherein in the step of setting the CRBT, the CBC copies the CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal.

8. The method according to any one of the preceding claims, wherein the CRBT setting request message further instructs to set the CRBT similar to or associated with that received by the calling terminal to be only received by the called terminal when the called terminal calls the calling terminal.

9. The method according to any one of the preceding claims, wherein in the step of setting the CRBT, the CBC sets the CRBT similar to or associated with that received by the calling terminal into the CRBT library for the calling terminal, and sets the CRBT to be only received by the called terminal when the called terminal calls the calling terminal.

10. The method according to any one of the preceding claims, wherein in the step of setting the CRBT, the CBC sets a serial number of the CRBT same as similar to or associated with that received by the calling terminal to the CRBT library for the calling terminal.

11. The method according to any one of the preceding claims, wherein the step of authenticating is performed by the CBC.

12. The method according to any one of the preceding claims, wherein the step of authenticating comprises:

13. The method according to any one of the preceding claims, after the step of setting the CRBT, further comprising:

14. The method according to any one of the preceding claims, wherein the communication network is a mobile communication network, and the calling terminal and the called terminal are mobile communication terminals.

15. The method according to any one of the preceding claims, wherein the step of authenticating comprises:

detecting, by a mobile switching center of the calling terminal, a home location register of the calling terminal to judge whether the calling terminal already activated the CRBT service.

16. The method according to any one of the preceding claims, wherein the called terminal is charged for the CRBT service activation fee in case that the CRBT setting request message is sent by the called terminal.

17. The method according to any one of the preceding claims, wherein in the step of activating the CRBT service, after the called terminal responds to the CRBT service activation message so as to activate the CRBT service for the calling terminal, the CBC further sends a message to the calling terminal to require the calling terminal to determine whether to activate the CRBT service, and after the calling terminal responds with a message to decide to activate the CRBT service, activates the CRBT service for the calling terminal.

18. The method according to any one of the preceding claims, wherein the CRBT is an audio CRBT or a video CRBT.

19. The method according to any one of the preceding claims, wherein the communication network is a fixed-line telephone network, and the calling terminal and the called terminal are fixed-line telephone terminals.
