Detailed Description
In order to further explain the method, the apparatus and the computer readable storage medium for playing the ring back tone according to the embodiments of the present invention, the following description is made in detail with reference to the accompanying drawings.
As described in the background art, in the called ring back tone service in the prior art, the called terminal sets a ring back tone for the calling terminal according to the preference of the called terminal, so that the ring back tone set by the called terminal cannot give consideration to the taste of the calling terminal, and most of the calling terminals are forced to listen to the ring back tone, and the called ring back tone service cannot realize that the personalized ring back tone of the called terminal is displayed while the taste of the calling terminal is given consideration to the taste of the calling terminal. Based on the above problems, the inventor of the present application has found through research that when a ringback tone is played for a calling terminal, feedback information of the calling terminal may be obtained first, and it is determined according to the feedback information what type of ringback tone is played to be more suitable for the taste of the calling terminal, and after knowing the taste of the calling terminal, a suitable ringback tone is recommended for the calling terminal, so that more targeted ringback tone recommendation and personalized customization can be performed for different calling terminals.
Specifically, an embodiment of the present invention provides a method for playing a ring back tone, where the method is applied to a scenario shown in fig. 1, where the scenario includes a calling terminal 10 and a server 20 serving the calling terminal 10, the server 20 may be a cloud intelligent network server, and communication can be implemented between the calling terminal 10 and the server 20. The method for playing the ring back tone provided by the embodiment of the invention is mainly applied to the situation that the called terminal 30 answers or hangs up after the calling terminal 10 initiates a call request to the called terminal 30. It should be noted that the hang-up of the called terminal 30 includes the rejection of the called terminal 30 or the absence of the call.
Referring to fig. 2, a method for playing a ring back tone according to an embodiment of the present invention includes:
102, determining the ring back tone preference information of the calling terminal according to the feedback information of the calling terminal; furthermore, the server analyzes the feedback information fed back by the calling terminal, so as to determine the ringback tone preference information of the calling terminal, wherein the ringback tone preference information reflects the preference degree of each ringback tone by the calling terminal.
103, according to the ring-back tone preference information of the calling terminal, matching the ring-back tone preference information from the called ring-back tone library to obtain a recommended ring-back tone; more specifically, the server selects a ring back tone meeting the taste of the calling terminal from the called ring back tone library as a recommended ring back tone according to the ring back tone preference information of the calling terminal. The called ring tone library is a ring back tone library which the called terminal has after handling the ring back tone service, and the called terminal can select the ring back tone played by the calling terminal from the called ring tone library, namely, when the calling terminal initiates a call request to the called terminal which handles the ring back tone service, the calling terminal can receive the ring back tone in the called ring back tone library. In addition, the ring-back tones in the called ring-back tone library are all ring-back tones selected according to own preferences when the called terminal transacts the ring-back tone service.
And step 104, playing the recommended ring back tone to the calling terminal.
In the method for playing the ring back tone provided by the embodiment of the invention, the feedback information fed back by the calling terminal can be acquired, the ring back tone preference information of the calling terminal can be analyzed according to the feedback information, the ring back tone preference information reflects the preference degree of the calling terminal to each ring back tone, and the ring back tone which meets the taste of the calling terminal is selected from the called ring back tone library and played for the calling terminal according to the ring back tone preference information.
In addition, the method for playing the ring back tone provided by the embodiment of the invention analyzes the taste of the calling terminal according to the feedback information fed back by the calling terminal, adopts the human-oriented recommendation algorithm design, and well makes up for the defect that the mode for playing the ring back tone in the prior art is too single (only set by the called terminal according to the subjective idea of the called terminal). In addition, in the method for playing the ring back tone provided by the embodiment of the invention, the preference information of the calling terminal to the ring back tone can be analyzed and obtained only according to the feedback information fed back by the calling terminal without using big data, so that the problems of difficult implementation, overlong period and the like caused by using the big data are avoided.
Referring to fig. 3, step 102 provided in the foregoing embodiment determines the ringback tone preference information of the calling terminal according to the feedback information of the calling terminal, specifically including the following steps:
specifically, the server may obtain a calling ring tone library of the calling terminal according to the calling number fed back by the calling terminal (in a case where the ring back tone service is enabled by the calling terminal), obtain a called ring tone library of the called terminal according to the called number fed back by the calling terminal, and may also obtain a toll-free ring tone library. In addition, when the calling terminal and the called terminal have corresponding history playing ring sound libraries, the server can also obtain the calling history playing ring sound library of the calling terminal according to the calling number and obtain the called history playing ring sound library of the called terminal according to the called number. After obtaining the various types of ring sound libraries, the server can establish a ring sound dimension model according to one or more of the called ring sound library, the calling historical play ring sound library, the called historical play ring sound library and the free ring sound library.
It should be noted that the above-mentioned calling ring tone library refers to a ring back tone library that the calling terminal has after handling the ring back tone service, and when other terminals initiate a call request to the calling terminal that has handled the ring back tone service, the other terminals can hear the ring back tone in the calling ring back tone library. And the ring-back tones in the calling ring-back tone library are all ring-back tones selected according to own preferences when the calling terminal transacts the ring-back tone service. The history playing ring tone library comprises a calling history playing ring tone library and a called history playing ring tone library, wherein the calling history playing ring tone library is a ring tone library formed by calling ring back tones which are played by a calling terminal once, and the called history playing ring tone library is a ring tone library formed by called ring back tones which are played by a called terminal once. The free ring tone library refers to a ring tone library which is freely provided by an operator for a called terminal and/or a calling terminal, and can be used even if the called terminal and/or the calling terminal do not handle a ring tone service. For example: when the operator provides a free ring library for the called terminal which does not handle the ring back tone service, the called terminal can also select the ring back tone from the free ring library to play for the calling terminal. The ring tone dimension model refers to that each ring tone included in the ring tone library for establishing the ring tone dimension model represents a dimension, respectively, to form a spatial ring tone dimension model, for example: when a ring tone dimension model is established according to the three ring back tones, a three-dimensional ring tone dimension model can be established; when the ring tone dimension model is established according to the ring back tone more than three, the multidimensional ring tone dimension model can be established.
And step 1024, determining the ring back tone preference information of the calling terminal according to the similarity between the calling ring back tone evaluation vector and the called ring back tone evaluation vector.
The server can calculate the similarity between the evaluation vector of the calling ring back tone and the evaluation vector of the called ring back tone in various ways, optionally, a cosine value calculation formula of a vector included angle shown as formula I is adopted to calculate the similarity between the evaluation vector of the calling ring back tone and the evaluation vector of the called ring back tone, when the included angle of the two vectors is 0 degree, the calculated cosine value is 1, which indicates that the tastes of the calling terminal and the called terminal are completely the same, and when the included angle of the two vectors is 180 degrees, the calculated cosine value is-1, which indicates that the tastes of the calling terminal and the called terminal are opposite.
Wherein x isiRepresenting the i-th component, y, in the caller ringback tone evaluation vectoriRepresenting the ith component in the called ring back tone rating vector. After the similarity between the evaluation vector of the calling ring back tone and the evaluation vector of the called ring back tone is obtained through calculation, the ring back tone preference information of the calling terminal is determined according to the obtained similarity.
It can be seen from the above process of determining the ringback tone preference information of the calling terminal according to the feedback information of the calling terminal that, in the method for playing the ringback tone provided by the embodiment of the present invention, the method for analyzing the preference information of the calling terminal to the ringback tone has a high accuracy, the implementation process is simple and efficient, no additional hardware is required, and the reconstruction is very convenient on the basis of the existing system.
It should be noted that the ring tone evaluation information of the called terminal corresponds to the feedback information fed back by the calling terminal, for example: when the feedback information fed back by the calling terminal is calling position information, the ring tone evaluation information of the called terminal is called position information of the called terminal, and the called position information of the called terminal can be obtained by the server according to a called number; for another example: when the feedback information fed back by the calling terminal is the interactive action information, and the interactive action information reflects the evaluation of the ring back tone played by the calling terminal, the ring back tone evaluation information of the called terminal also reflects the evaluation information of the ring back tone played by the called terminal, and the evaluation information reflecting the ring back tone played by the called terminal can be obtained by the server according to the playing frequency statistics of different ring back tones, or can be preset by the called user of the called terminal.
Taking the feedback information fed back by the calling terminal as the interactive action information as an example, in step 1022, the obtaining of the evaluation vector of the caller ringback tone according to the feedback information fed back by the calling terminal and the ringtone dimension model may specifically include: determining calling quantization indexes corresponding to the ring tone dimension models according to the interactive action information fed back by the calling terminal; and obtaining the evaluation vector of the calling ring back tone according to the calling quantization index and the ring back tone dimension model. Furthermore, when the feedback information fed back by the calling terminal is the interactive action information, the interactive action information can be determined as the calling quantization index of the corresponding ring tone dimension model, and the coordinates corresponding to each dimension (the coordinates of each dimension represent the likeness degree of the ring back tone corresponding to the dimension) are marked on the ring tone dimension model according to the determined calling quantization index, so that the calling ring back tone evaluation vector is obtained.
It should be noted that the interactive action information fed back by the calling terminal reflects the evaluation made by the calling terminal on the ring back tone when listening to the played ring back tone, and the interactive action information may be acquired through various interactive modes, for example: key interaction, sliding interaction, short message interaction or shaking interaction and the like. Taking the key interaction as an example: setting different keys to represent different evaluations, specifically setting the key 1 as a switch key, pressing the switch key to indicate that a calling user of the calling terminal does not like the currently played ring back tone, and when the server receives the information of the switch key fed back by the calling terminal, the server can control the calling terminal to play the next recommended ring back tone. The setting key 2 is a copy key, pressing the copy key indicates that the calling terminal likes the ring back tone played by the calling terminal, and decides to copy the ring back tone into the personal ring back tone library, and after the calling user of the calling terminal presses the copy key, the automatic account opening (for the calling terminal of the non-polyphonic ringtone user) and purchasing actions can be realized. Setting the key 3 as a sharing key, and pressing the sharing key indicates that the calling terminal decides to share the ringtone with other people. Setting the key 4 as a black-out key, pressing the black-out key to indicate that the calling terminal hopes to shield the ring tone, and when the server receives the information of the black-out key fed back by the calling terminal, the server can control the calling terminal to play the next recommended ring back tone.
In the above step 1023, according to the ring tone evaluation information and the ring tone dimension model of the called terminal, a called ring back tone evaluation vector is obtained, which specifically includes: determining a called quantization index corresponding to the ring tone dimension model according to ring tone evaluation information of a called terminal; and obtaining a called ring back tone evaluation vector according to the called quantization index and the ring tone dimension model. More specifically, when the caller ringback tone evaluation vector is the interactive action information fed back by the caller terminal, the server may obtain the ringtone evaluation information of the called terminal through the called number, and mark the coordinates corresponding to the dimensions on the ringtone dimension according to the determined called quantization index, by using the ringtone evaluation information of the called terminal as the called quantization index of the corresponding ringtone dimension model, thereby obtaining the called ringback tone evaluation vector.
It should be noted that when information such as location information and environment information is used as a quantization index of a corresponding ring tone dimension model, it is also necessary to obtain ring tone attributes of ring back tones represented by each dimension in the ring tone dimension model, for example: silence, sunlight, depression, language type, etc., by combining information such as location information, environmental information, etc. with the ring tone attributes, a ring back tone evaluation vector is obtained.
Referring to fig. 4, step 103 provided in the foregoing embodiment matches a recommended ring back tone from a called ring back tone library according to the ring back tone preference information of the calling terminal, and specifically includes the following steps:
In order to describe the method for playing a ring back tone in more detail, several specific embodiments are given below.
Taking the called ring tone library including three called ring-back tones as an example, for convenience of description, defining three called ring-back tones included in the called ring tone library as R1, R2 and R3, establishing a ring tone dimension model according to the called ring tone library, regarding each ring-back tone in the called ring tone library as one dimension, regarding the three ring-back tones as three dimensions of a three-dimensional space, setting R1 to represent an x axis, R2 to represent a y axis, and R3 to represent a z axis. The method comprises the steps of taking interactive action information fed back by a calling terminal as a calling quantization index, quantizing the interactive action information into a specific numerical value of the calling terminal on the liking degree of a ring back tone, setting the coordinate value of the ring back tone played completely (without any key input until no response or connection in the listening process) by the calling terminal to be 1, setting the coordinate value of a switching key pressed by the calling terminal to be-1, setting the coordinate value of a copying key pressed by the calling terminal to be 5, setting the coordinate value of a sharing key pressed by the calling terminal to be 3, setting the coordinate value of a black key pressed by the calling terminal to be-4, and marking the coordinate value on each dimension in an established ring back tone dimension model according to the interactive action information so as to obtain a calling ring back tone evaluation vector of the calling terminal aiming.
Setting the calling terminal pressing the copy key when listening to the ring back tone R1 and pressing the switch key when listening to the ring back tone R2 and the ring back tone R3 can obtain the calling ring back tone evaluation vector V of the corresponding calling terminala1(5, -1, -1). Because the ring-back tones R1, R2 and R3 are ring-back tones in the called ring-back tone library, each ring-back tone is liked by the called terminal, the liked degrees of the called terminal to R1, R2 and R3 are obtained according to the ring-back tone evaluation information of the called terminal, and the called ring-back tone evaluation vector V of the called terminal is obtainedb1(1, -1, 3). Evaluating vector V of calling ring back tonea1And called ring back tone rating vector Vb1Substituting into the formula I to obtain the cosine values of the included angles of the two vectors as follows: cos (V)a1,Vb1)＝0.174。

According to the result of the cosine value calculation, the calling terminal can be played in the sequence of R3, R2 and R1 to meet the taste of the calling terminal for the same called ring tone library.
In addition, position information fed back by the calling terminal can be used as a calling quantization index, specifically, feedback information fed back by the calling terminal comprises calling position information and a called number, and after the server receives the feedback information, the server can determine the position of the calling terminal according to the calling position information, determine called position information of the called terminal according to the called number, and further determine the position of the called terminal.
Setting calling position information to display that calling terminal is in American quiltThe called position information shows that the called terminal is in the Guangdong, the three called ring-back tones R1, R2 and R3 are Minnan Song, Yue Song and English Song respectively, and the evaluation vector of the calling ring-back tone is determined to be Va1With (3,1,5), the called ring-back tone rating vector is Vb3(3,5,1), and evaluating the calling ring back tone vector Va1And called ring back tone rating vector Vb3Substituting the cosine values into the formula I to obtain cosine values of an included angle between the two vectors, if the obtained cosine values are smaller, adjusting the sequence of ring back tones played by the calling terminal, then calculating corresponding cosine values until proper cosine values are obtained, and playing the ring back tones for the calling terminal according to the sequence of playing the ring back tones corresponding to the proper cosine values.
