DETAIL DESCRIPTION OF EMBODIMENTS

To improve understanding of technical solutions of the present disclosure for those skilled in the art, the multimedia file distribution method, the multimedia control method, the multimedia management platform, the caller ring back tone platform, and the computer-readable storage medium according to the present disclosure will be described below in detail in conjunction with the accompanying drawings.

Example embodiments will be described more sufficiently below with reference to the accompanying drawings, but they may be embodied in different forms and should not be construed as limited to those set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

Implementations of the present disclosure and features thereof may be combined with each other, as long as they are not contradictory.

As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the present disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that as used herein, the terms “comprise/include” and/or “consist of . . . ” specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the existing art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

FIG. 1 is a schematic structural diagram of a caller ring back tone system. As shown in FIG. 1, an existing caller ring back tone system includes a caller ring back tone platform and an audio ring tone management system arranged in different regions (e.g., provinces). The audio ring tone management system is configured to manage audio files of caller ring back tones and distribute the audio files of caller ring back tones to caller ring back tone platforms. In FIG. 1, a number of a terminal A belongs to a region A, and a number of a terminal B belongs to a region B. When the terminal A serving as a calling party calls the terminal B serving as a called party, the caller ring back tone platform of a home location (the region B) of the terminal B is triggered to play the caller ring back tone subscribed by the terminal B to the terminal A via a backbone core network.

It is found in researches that, in the existing caller ring back tone system shown in FIG. 1, during communication between terminals with numbers belonging to different home locations, the playing of the caller ring back tone is equivalent to playing offsite, which has a relatively high requirement on a transmission bandwidth of the backbone core network. Particularly, with the rise of the video caller ring back tone, the existing caller ring back tone system shown in FIG. 1 faces following problems: in a case where the backbone core network is unstable or a relatively large audio/video file is being played, the user experience may be deteriorated due to a transmission delay; and in the existing caller ring back tone system, the audio ring tone management system sends audio and video files of all caller ring back tones to caller ring back tone platforms in a full distribution mode, which means that each caller ring back tone platform stores the audio and video files completely, resulting in increased storage costs without improving the user experience.

In view of above, referring to FIG. 2, an embodiment of the present disclosure provides a multimedia file distribution method, including: operations S100 and S200.

At operation S100, determining an offsite calling associated number corresponding to at least one subscriber number, with the offsite calling associated number corresponding to the subscriber number being a number of a terminal with a number of calls to the subscriber number exceeding a first threshold, and a home location of the offsite calling associated number being different from that of the subscriber number corresponding to the offsite calling associated number.

At operation S200, distributing a multimedia file associated with the subscriber number to a caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number.

The embodiment of the present disclosure is intended to distribute, through a certain multimedia file distribution policy, the multimedia file of the caller ring back tone subscribed by the called party to the caller ring back tone platform of the home location of the calling party, so that, during the calling party calls the called party, the caller ring back tone subscribed by the called party can be played for the calling party by the caller ring back tone platform of the home location of the calling party.

It should be noted that, in the present disclosure, the subscriber number in operation S100 is regarded as a called party number, and the offsite calling associated number corresponding to the subscriber number is regarded as a calling party number. The subscriber number is a number of a user who has subscribed to the caller ring back tone service; and the multimedia file associated with the subscriber number is a multimedia file corresponding to the caller ring back tone subscribed by the subscriber number.

It should be further noted that, for each subscriber number, there may be zero, one, or more offsite calling associated numbers corresponding thereto, which is not limited in the present disclosure.

In the present disclosure, as a calling or called role of the subscriber number changes, the offsite calling associated number corresponding to the subscriber number may change accordingly. By performing operation S100 periodically or aperiodically, the offsite calling associated number corresponding to the subscriber number changed can be determined, and in operation S200, the multimedia file associated with the subscriber number is distributed to the caller ring back tone platform of the home location of the offsite calling associated number changed. That is, in the present disclosure, the policy for the multimedia management platform to distribute the multimedia file may be dynamically adjusted according to changing of the calling or called role of the subscriber number.

In the present disclosure, the multimedia management platform distributes the multimedia file to the caller ring back tone platform in a non-full distribution mode, which means that, after the multimedia file associated with the called party number is distributed to the caller ring back tone platform of the home location of the calling party number in operation S200, the multimedia file associated with the called party number that is frequently called during a local terminal serving as the calling party is stored in the caller ring back tone platform, and in an implementation, the multimedia file corresponding to the caller ring back tone subscribed by the local terminal is further stored in the caller ring back tone platform. The multimedia management platform will not distribute all multimedia files to each caller ring back tone platform any more.

It should be noted that, in the present disclosure, since the multimedia file associated with the called party number that is frequently called during the local terminal serving as the calling party, and the multimedia file corresponding to the caller ring back tone subscribed by the local terminal, are stored in the caller ring back tone platform, during the terminal serving as the calling party calling the terminal serving as the called party, the caller ring back tone subscribed by the terminal serving as the called party can be played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the calling party number in most cases; and in other cases, if the multimedia file associated with the called party number is not stored in the caller ring back tone platform of the home location of the calling party, the caller ring back tone subscribed by the called party terminal may be played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the called party number. Therefore, in the present disclosure, the multimedia management platform distributes the multimedia file to the caller ring back tone platform in a non-full distribution mode, so that a normal operation of the caller ring back tone service can be ensured, and in most cases, the caller ring back tone subscribed by the terminal serving as the called party can be played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the calling party number.

It should be further noted that, in the present disclosure, the multimedia file may be an audio file, a video file, or any other type of multimedia file, which is not limited in the present disclosure.

In the multimedia file distribution method according to the present disclosure, the multimedia management platform distributes the multimedia file associated with the called party number to the caller ring back tone platform of the home location of the calling party number that frequently calls the called party number, so that in most cases, the caller ring back tone subscribed by the terminal serving as the called party can be played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the calling party number, and in a case where the multimedia file associated with the called party number is not stored in the caller ring back tone platform of the home location of the calling party, the caller ring back tone subscribed by the terminal serving as the called party may be played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the called party number, so that a normal operation of the caller ring back tone service can be ensured in a case where the multimedia management platform distributes the multimedia file to the caller ring back tone platform in a non-full distribution mode. In addition, with the non-full distribution mode, a number of multimedia files to be stored by the caller ring back tone platform are reduced, and a storage space of the caller ring back tone platform is saved, and in a case where the caller ring back tone subscribed by the terminal serving as the called party is played to the terminal serving as the calling party by the caller ring back tone platform of the home location of the calling party number, a load on a backbone network caused by offsite playing is avoided, operation and maintenance costs of an operator for the backbone network are reduced, and furthermore, since a transmission distance between the caller ring back tone platform playing the caller ring back tone and the terminal serving as the calling party is shortened, an effect of playing the caller ring back tone and the user experience are improved.

In the present disclosure, the offsite calling associated number corresponding to the subscriber number may be determined according to a static or dynamic distribution policy, and the multimedia file associated with the subscriber number is distributed to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number. The static distribution policy includes determining, according to the calling or called role of the subscriber number locally stored at the multimedia management platform, the offsite calling associated number corresponding to the subscriber number, and distributing the multimedia file associated with the subscriber number to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number. The dynamic distribution policy includes receiving the calling or called role of the subscriber number sent from the caller ring back tone platform, determining the offsite calling associated number corresponding to the subscriber number in real time, and distributing the multimedia file associated with the subscriber number in real time to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number.

In an implementation, the multimedia management platform distributes the multimedia file according to the static distribution policy. The multimedia management platform locally stores the subscriber number and calling or called information of the subscriber number, and determines the offsite calling associated number corresponding to the subscriber number based on the subscriber number and the calling or called information of the subscriber number locally stored.

Accordingly, referring to FIG. 3, the operation S100 may include operations S101 and S102.

At operation S101, determining locally stored information of a home location of a calling associated number corresponding to the subscriber number, with the calling associated number corresponding to the subscriber number being the number of the terminal with the number of calls to the subscriber number exceeding the first threshold.

At operation S102, determining the calling associated number with a home location different from that of the subscriber number as the offsite calling associated number corresponding to the subscriber number.

It should be noted that, in the present disclosure, the multimedia management platform locally stores at least one subscriber number and the calling or called information of the subscriber number, and subscriber numbers may belong to different home locations or belong to a same home location, which is not limited in the present disclosure.

In the present disclosure, each multimedia file in the multimedia management platform has a unique identifier (ID) to be distinguished from others. In an implementation, the multimedia management platform stores a correspondence relationship between subscriber numbers and identifiers (IDs) of multimedia files, so that each subscriber number is to be associated with the multimedia file corresponding to the caller ring back tone subscribed by the subscriber number.

Accordingly, in an implementation, referring to FIG. 4, the operation S200 may include operations S201 and S202.

At operation S201, determining, according to the ID of the multimedia file associated with the subscriber number locally stored, the multimedia file associated with the subscriber number.

At operation S202, distributing the determined multimedia file associated with the subscriber number to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number.

In an implementation, the multimedia management platform distributes the multimedia file according to the dynamic distribution policy. The multimedia management platform may receive the subscriber number and the calling or called information of the subscriber number sent from the caller ring back tone platform, and determine in real time, based on the subscriber number and the calling or called information of subscriber number received, the offsite calling associated number corresponding to the subscriber number.

Accordingly, referring to FIG. 5, the operation S100 may include operations S111, S112 and S113.

At operation S111, receiving a calling associated number corresponding to the subscriber number sent from the caller ring back tone platform, with the calling associated number corresponding to the subscriber number being the number of the terminal with the number of calls to the subscriber number exceeding the first threshold.

At operation S112, determining information of a home location of the calling associated number.

At operation S113, determining the calling associated number with a home location different from that of the subscriber number as the offsite calling associated number corresponding to the subscriber number.

It should be noted that, in the present disclosure, each caller ring back tone platform sends at least one subscriber number and the calling or called information corresponding to the subscriber number each time, and subscriber numbers sent from each caller ring back tone platform belong to the same home location.

As described above, in the present disclosure, each multimedia file in the multimedia management platform has a unique ID to be distinguished from others. In an implementation, the caller ring back tone platform sends the correspondence relationship between the subscriber numbers and the IDs of the multimedia files associated with the subscriber numbers to the multimedia management platform, and the multimedia management platform distributes, according to the correspondence relationship received, the multimedia file corresponding to the subscriber number to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number.

Accordingly, referring to FIG. 6, the operation S200 may include operations S211,

At operation S211, receiving an ID of the multimedia file associated with the subscriber number sent from the caller ring back tone platform.

At operation S212, determining, according to the ID of the multimedia file associated with the subscriber number, the multimedia file associated with the subscriber number.

First Example

FIG. 21 is a schematic diagram of an implementation of a caller ring back tone system according to the present disclosure. In FIG. 21, the home location of the calling party number is a region A, and the home location of the called party number is a region B.

As shown in FIG. 21, the multimedia management platform includes a ring tone distribution module and a policy computation module. The ring tone distribution module is configured to distribute the multimedia file to the caller ring back tone platform, and the policy computation module is configured to generate a multimedia file distribution policy.

As shown in FIG. 21, the caller ring back tone platform includes a ring tone management module, a signaling control module, a media control module, and an information analysis module. The ring tone management module is configured to receive and manage the multimedia file distributed by the multimedia management platform; the signaling control module is configured to transmit signaling among different caller color ring platforms, where signaling control modules of the different caller ring platforms are connected through a backbone core network; the media control module is configured to control playing of the multimedia file; and the information analysis module is configured to perform aggregation analysis on a local subscriber number to obtain a calling party number which frequently calls the local subscriber number, and generate calling associated information. The information analysis module is further configured to analyze and determine, according to preferences, habits and the like of a local user for setting the caller ring back tone, the multimedia file with a higher probability of being set as the caller ring back tone by the local user, and then send an ID of the multimedia file determined to the policy computation module of the multimedia management platform so that the multimedia management platform distributes the multimedia file to the caller ring back tone platform of the home location of the offsite calling associated number corresponding to the subscriber number with a home location being the location where the caller ring back tone platform that sent the ID of the multimedia file is located.

It should be noted that FIG. 21 merely shows a case where the caller ring back tone platform in the region B includes the information analysis module, but the caller ring back tone platform in the region A does not include the information analysis module. It will be appreciated that in a scenario where the home location of the calling party number is the region B and the home location of the called party number is the region A, the caller ring back tone platform in the region A also includes the information analysis module.

Second Example

In this example, as shown in FIG. 21, the caller ring back tone platform adopted here is the caller ring back tone platform in the first example. In FIG. 21, the home location of the calling party number is the region A, and the home location of the called party number is the region B.

The multimedia management platform operates in a non-full distribution mode, and distributes the multimedia file to the caller ring back tone platform in the region A according to a static distribution policy. The caller ring back tone platform in the region A receives the ring tone synchronized by the multimedia management platform, and stores information such as the calling party number, the ID of the ring tone and the like. When a terminal in the region A calls a number of a terminal in the region B, the signaling control module of the caller ring back tone platform in the region B notifies the signaling control module of the caller ring back tone platform in the region A to play the multimedia file associated with the called party number. The multimedia file associated with the called party number is stored in the caller ring back tone platform in the region A, and the media control model in the caller ring back tone platform in the region A plays the multimedia file to the calling party number with the home location being the region A.

It should be noted that in the second example, the static distribution policy includes that: the policy computation module obtains, according to calling group information stored locally in the multimedia management platform, information of the calling party number corresponding to a number with a home location being the region B, and an ID of the multimedia file associated with the calling party number, then determines an offsite calling associated number (i.e., a number with a home location being the region A) according to information of the home location of the calling party number corresponding to the number with the home location being the region B, and directionally distributes the multimedia file associated with the number with the home location being the region B to the caller ring back tone platform in the region A through the ring tone distribution module. The ring tone distribution module distributes, according to hot ring tones published, multimedia files corresponding to the hot ring tones to caller ring back tone platforms respectively.

Third Example

In a third example, as shown in FIG. 21, the caller ring back tone platform adopted here is the caller ring back tone platform in the first example. In FIG. 21, the home location of the calling party number is the region A, and the home location of the called party number is the region B.

The multimedia management platform operates in a non-full distribution mode. Caller ring back tone platforms in the region A and the region B receive multimedia files synchronized by the multimedia management platform. During a terminal in the region A calls a number of a terminal in the region B, the signaling control module of the caller ring back tone platform in the region B notifies the signaling control module of the caller ring back tone platform in the region A to play the multimedia file associated with the called party number. In a case where the multimedia file associated with the called party number is not stored in the caller ring back tone platform in the region A, the signaling control module of the caller ring back tone platform in the region A notifies the caller ring back tone platform in the region A, the media control model of the caller ring back tone platform in the region B plays the multimedia file associated with the called party number to the calling party number with the home location being the region A. The caller ring back tone platform in the region B sends a message to the multimedia management platform, the message including information of the calling party, an ID of the multimedia file associated with the called party number, and the like. The policy computation module in the multimedia management platform extracts the information of the calling party, the ID of the multimedia file associated with the called party number, and the like from the message received, and distributes the multimedia file associated with the called party number to the caller ring back tone platform in the region A through the ring tone distribution module. In a case where the terminal in the region A calls the number of the terminal in the region B again, and the multimedia file associated with the called party number is played to the terminal in the region A by the caller ring back tone platform in the region A.

Fourth Example

In a fourth example, as shown in FIG. 21, the caller ring back tone platform adopted here is the caller ring back tone platform in the first example. In FIG. 21, the home location of the calling party number is the region A, and the home location of the called party number is the region B.

During a terminal in the region A calls a terminal in the region B, the signaling control module of the caller ring back tone platform in the region B sends information relating to calling and called parties to the information analysis module of the caller ring back tone platform in the region B. The information analysis module of the caller ring back tone platform in the region B stores the information relating to the calling and called parties. The information analysis module of the caller ring back tone platform in the region B performs periodical smart analysis on the information relating to the calling and called parties, for example, performs aggregation according to the called party number to obtain the calling party number which frequently calls the called party number. The information analysis module of the caller ring back tone platform in the region B sends the information of the calling party, the ID of the multimedia file associated with the called party number, and the like to the policy computation module of the multimedia management platform. The policy computation module in the multimedia management platform judges whether the calling party number and the called party number belong to a same home location. In a case where the calling party number and the called party number belong to different home locations, the policy computation module of the multimedia management platform distributes, according to the information of the calling party, the ID of the multimedia file associated with the called party number, and the like, the multimedia file associated with the called party number to the caller ring back tone platform in the region A through the ring tone distribution module. In a case where the terminal in the region A calls the number of the terminal in the region B again, the multimedia file associated with the called party number is played to the terminal in the region A by the caller ring back tone platform in the region A.
