Description

Realization method of personalized ring back tone

technical field

The invention relates to a call feedback method in communication, in particular to a method for providing customized feedback information to a calling user according to the state of the called user.

Background technique

Currently in China, there are nearly 250 million mobile phone users, and the network and users are still developing rapidly, which provides a broad foundation for the development of mobile value-added services. At the same time, the quality of mobile users is high and their demand for information is high. The needs of users are increasingly diversified and personalized. This can be seen from the widespread popularity of services such as ringtone downloads and MMS in the market. If mobile operators can make full use of existing network resources to provide users with a variety of value-added services, they can greatly improve economic benefits. Thus, the personalized ring back tone service came into being.

Ringback tone is a signal tone. When a calling user dials for wired or wireless telephone communication, it takes about 3 to 10 seconds from the called user to hear the ringing to pick up the phone. During this time, A signal tone that the calling user can hear to indicate that the call signal is being sent to the called telephone set is called a ringback tone. The ring back tone is divided into a busy tone indicating that the called user's phone is currently busy and a ringing tone indicating that the called user is ready to receive a call. Various tones can be used as ringback tones depending on the type of telephone or switching system. The ringback tone is selected from the read-only memory (Read Only Memory, referred to as "ROM") installed in the switching system of the telephone office, and sent to the calling user. Therefore as long as the ring back tone in the ROM of the switching system is not changed, the calling subscriber can only hear a ring back tone.

The personalized ring back tone service is also called the coloring ring back tone service (Coloring Ring Back Tone, referred to as "CRBT"), which is a service that takes effect when the user is the called user. Specifically, the user who applies for the service can set, set or manage the ringback tone sent back to the user who called him in various ways. When a user calls the user, what the calling user hears is no longer monotonous. The "beep, beep" ringback tone is a personalized ringback tone set by the called user in the system. The ringback tone can be a piece of music, or some humanized message such as a message set by the called user himself. Response. These personalized ring back tones are pre-set by the called user. It can be provided by the system, or it can be a voice file recorded by the called user through the personalized ring back tone service system in advance, or the called user can send it through the network in advance. Voice files downloaded to the personalized ring back tone service system.

There are many methods for network realization of the personalized ring back tone service. In general, it can be divided into two categories: 1. Change part of the business process of the switching system to provide multiplication services. However, this solution requires changes to all switching systems in the entire network, involving all equipment suppliers, and the construction period Long, this solution is more suitable for operators with relatively concentrated types of equipment models; 2. The frame structure based on the intelligent network platform is realized by adding peripheral intelligent peripherals, and the system provides personalized ring back tone by adding service nodes For services, this solution does not require major changes in the business process of the switching system, but only needs to add a music ringback server entity, which can provide services in a relatively fast time.

The most basic feature of the personalized ring back tone service is to replace the traditional ring back tone with customized sounds and provide a more friendly calling interface. It has the following service characteristics: First, the service is applied by the called user, and by triggering the called service process, according to the service data provided by the called user when applying for the service, different music is played to the calling user instead of the traditional Second, users who apply for this service can classify calling users and customize ring-back tones for each type of calling user. The service matches the service data according to the calling user's number and plays it back to different calling users Customized music. If the calling number is IP phone, fixed-line phone, international phone, etc., there may be cases where the number is garbled, the default ringtone will be used as the ringback tone; finally, there are a large number of ringback Modify the ringback tone anywhere.

In actual application, the above-mentioned scheme has the following problems: on the one hand, the ring-back tone played has a single type and lacks sufficient personalization: the ring-back tone can only be played to the calling user when the called user is free; The playing of the ring tone cannot vary with the change of the calling time, calling number, roaming location of the called user and the state of the called user.

The main reason for this situation is that the playback of the ring back tone does not take into account factors such as the call time, the roaming location of the called user, the state of the called user, and the combination of different factors.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a kind of implementation method of personalized ring back tone, so that the service of more personalized ring back tone can be provided to users, that is, according to calling time, calling number, called user's roaming position Different ring back tones are provided depending on the state of the called user.

In order to achieve the above object, the invention provides a kind of implementation method of personalized ring back tone, comprising the following steps:

When the network side equipment receives the ringing signaling from the called user terminal, it obtains the information of the calling user terminal, the called user terminal and the network side, and queries from the pre-set ringback tone list according to the acquired information ring back tone;

The network side device plays the queried ring back tone to the calling user terminal.

Wherein, the acquired information is the number of the calling user terminal, or the current time period, or the current location of the called user terminal, or one of the states of the called user terminal, or their random combination.

The network side device is an advanced intelligent peripheral or a mobile switching center.

The step of obtaining the information of the calling user terminal, the called user terminal and the network side includes the following sub-steps:

The network-side device obtains the number of the calling user terminal and the number of the called user terminal, as well as the status and current location of the called user terminal from the call signaling, and queries the current time on the network side.

The status of the called user terminal is power off, or roaming, or busy, or no network.

When the preset ring-back tone cannot be found, the default ring-back tone will be played.

When playing the ring back tone, a traditional ring tone is used as the background sound.

Stop playing the ring back tone when the called user terminal detects the termination event.

The termination event is that the called user terminal goes off-hook, or the called user terminal presses the rejection key, or the calling user terminal interrupts the call.

The called user terminal is a mobile phone, or an IP phone, or a fixed phone.

By comparison, it can be found that the difference between the technical solution of the present invention and the prior art is that the present invention comprehensively considers the four factors of the calling party number, call time, roaming position of the called party and the state of the called party and their combinations, and Play different ringback tones for calling users according to different combinations.

The difference in this technical solution has brought more obvious beneficial effects, that is, the ringback tone of the telephone set can be freely set according to different scenarios and the wishes of the called user, for different calling users, different time, called The user's current geographical location and status feed back different information to the calling user, which is more personalized and humanized. This function can provide additional value-added income for the communication operator, and attract more customers to join the network of the communication operator.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

At first it needs to be explained that the implementation of the personalized ring back tone service described in the present invention can be realized on multiple network structures, such as Global System for Mobile Communication (Global System for Mobile Communication, referred to as "GSM"), Code Division Multiple Access (Code Division Multiple Access) Division Multiple Access, referred to as "CDMA") mobile communication network, and even Public Switched Telephone Network (Public Switched Telephone Network, referred to as "PSTN") or Integrated Services Digital Network (Intergrated Services Digital Network, referred to as "ISDN").

The setting of ring back tone in the personalized ring back tone service described in the present invention can have following several methods: the one, select default ring back tone. Users can choose a sample from the system's ready-made sound library as the default ringback tone. Once the setting is completed, calls from other users (judged by the calling user) will use this sample as the ringback tone. If the user does not select the default ring back tone, the system default ring back tone will be used. The second is to choose different status prompt sounds. The status of the called user is about shutdown, roaming, busy, no network, etc. The selection of status can be combined with the setting of time period. In a preferred embodiment of the present invention, the shutdown prompt tone can be set according to the time period. If the user has the habit of taking a nap every day, a message prompt at 13:00-14:00 can be set: "I'm sorry, I'm taking a break, please take a moment." Call later." If the user has not set the status prompt tone, the user's personal default status prompt tone will be used; if the user has not personally set the status shutdown prompt tone, the system's default status prompt tone will be used. The third is to select personalized ring-back tones for different calling users. The user can set a personalized ring-back tone for a specific caller. After the setting is successful, the system will judge the caller of each call and play a predefined sound segment as the ring-back tone to the caller. The method for the user to select a sound segment is the same as the method for selecting the default ringback tone. The above three personalized ring-back tone selection modes can also be used in combination.

A preferred embodiment of the present invention is described in detail below.

FIG. 1 shows a schematic diagram of a communication system networking solution in an implementation manner of a personalized ring back tone service according to an embodiment of the present invention. As shown in the figure, the components of the communication system include: Mobile Switching Center (MSC for short) 11, Service Switching Point (SSP for short)/Intelligent Peripheral (IP for short) ") 12, Home Location Register ("HLR") 20, Service Control Point (Service Control Point, "SCP") 30, Gateway Mobile Switching Center (Gateway Mobile Switching Center, "GMSC") 40 , accessing a Mobile Service Switching Center (VisitMobile Switching Center, “VMSC” for short) 50 and an Advanced Intelligent Peripheral (Advanced Intelligent Peripheral, “AIP” for short) 60 . Among them, MSC11 is connected with SSP/IP12 to form a whole MSC/SSP/IP10. The system is centered on MSC/SSP/IP10, and HLR20, SCP30, GMSC40, VMSC50 and AIP60 are respectively connected to it.

MSC11, also known as a switch, is responsible for all switching and signaling functions in the area. It connects mobile origination (Mobile Origination, referred to as "MO") and mobile termination (Mobile Termination, referred to as "MT") mobile intelligent call routing to SSP/IP12, intelligent call processing by SSP/IP12.

SSP/IP12 realizes the triggering of MT intelligent call and the signaling interface function with SCP30, and also realizes functions such as business switching function and dedicated resource function. It tandems the intelligent calls from GMSC40 and MSC11, and performs corresponding intelligent call processing according to different services.

In a preferred embodiment of the present invention, the construction of SSP/IP12 can be combined with the construction of MSC11, so that one or several MSC11 in the network can act as the role of SSP/IP12 at the same time, so that they form a whole MSC/SSP/IP10.

GMSC40 is the part of MSC connected with PSTN/ISDN, it is responsible for querying and selecting calls from PSTN/ISDN to a certain MSC, and routing MT mobile intelligent calls to SSP/IP12, and SSP/IP12 performs intelligent call processing .

HLR20 is one of the most important databases in the system, which saves the data of all local network registered users, such as the location of the mobile phone, the service registered and used, etc.

The SCP30 stores the service control logic of the corresponding intelligent service to realize the flexible control of the mobile intelligent service. There is a No.7 signaling mobile application part signaling interface between HLR20 and SCP30, and SCP30 can use the "query at any time" operation to obtain the user's location information and user status.

AIP60 is the main device for realizing the personalized ring back tone service. It stores the personalized ring back tone data of the called user and can perform voice recognition. Combine the current location to customize different ringback tones. In a preferred embodiment of the present invention, the ISDN User Part protocol (Signaling System 7 ISDN User Part, "ISUP") is adopted between MSC11 and AIP60.

The working process of the system is briefly described as follows:

When the MSC11 or GMSC40 of the calling user end receives the MO or MT call, it will route the call to the corresponding SSP/IP12, and add a one to two-digit area prefix indicating the area where the current MSC or GMSC is located in front of the called number.

After the SSP/IP12 receives the MO call, it obtains the service key and SCP address information of the calling user according to the number segment, and obtains the location information of the calling user according to the special prefix before the called number, and then triggers the calling intelligent service process to transfer the service Key, calling number, called number, calling location information and other related information are reported to SCP30, and the MO intelligent call is completed according to the call control command of SCP30.

On the other hand, after receiving the MT call, the called user end SSP/IP12 obtains the service key and SCP address of the called user, and obtains the location information of the calling user according to the special prefix in front of the called number. At the same time, the SSP/IP12 triggers Before the called service process, at first the called roaming number will be retrieved from the called HLR20, the location information of the called user will be obtained according to the called user's roaming number, and then the called intelligent service process will be triggered, and the service key, calling number, The called number, calling location information, and called location information are reported to the SCP30, and then the MT intelligent call processing is completed according to the call control instruction of the SCP30. AIP60 can obtain intermediate number, called mobile station ISDN (Mobile System ISDN, "MSISDN") number, called location (called roaming number) and ring-back tone type according to incoming (MSC11) signaling and ring-back tone. If the called party is a user of the personalized ring back tone service, the AIP60 combines the conditions customized by the user to obtain the ring back tone customized by the called party and plays it to the calling user. In this way, the personalized ring back tone service can be realized.

In a preferred embodiment of the present invention, the personalized ring back tone service is a new value-added intelligent service based on the intelligent network platform, and is triggered by the called party's subscription information. In actual implementation, the existing intelligent network structure is used to load the business logic on the AIP60, of course, it can also be placed on the MSC11 or SCP30. On the SCP30 to which the user belongs, corresponding service control processing is performed, and music ring-back tone is provided to the user.

Referring to FIG. 2, the implementation process of the personalized ring back tone service will be described in detail.

As shown in Figure 2, when the called user terminal AIP receives the incoming signaling and the ring back tone, it enters step 201, and the AIP obtains the calling user number and the called user number from the incoming signaling, and then inquires about the status of the called user. Called user's current location and current call time, combine the four conditions of calling user number, called user status, called user's current location and current call time to query the ringback tone list customized by the called user.

Then enter step 202 to judge whether the combination of the current four conditions of the called user has a corresponding item in the ring back tone list. If yes, go to step 203; if not, go to step 204.

In step 203, the AIP plays the ring back tone customized by the called user to the calling user. From now on, until the calling user interrupts the call or the called user picks up the phone, the calling user will hear the ring back tone customized by the called user. After that, go to step 205 .

In step 204, the AIP plays a normal ring back tone to the calling party. After that, go to step 205 .

In step 205, if the called user terminal SCP sends the corresponding signal of the called user's phone set (the called user picks up the phone or presses the rejection key), or perceives the interruption signal of the calling user's phone (the calling user interrupts the call) call), the AIP stops sending the ringback tone. In other words, when the called user picks up the phone (response signal) after hearing the ringing of the phone, the called user end SCP perceives the response signal and transmits the response signal to the AIP. Then, the AIP stops sending the ringback tone and a call route is established by the two SCPs.

As mentioned above, according to the present invention, while the calling user hears the personalized ring back tone, the called user's phone is ringing; during this connection, the calling user may feel uncomfortable because he or she cannot be sure. Find out whether the called user's phone is ringing. Therefore, in a preferred embodiment of the present invention, the method of sending a traditional ringing tone as a background sound can be adopted.

Those skilled in the field of the present invention will understand that the above-mentioned service functions implemented in the AIP can also be implemented on network entities such as MSC and SCP without going beyond the spirit and scope of the present invention.

Those skilled in the art can understand that the personalized ring back tone information can be stored in various storage devices. It can be updated and modified in many ways. One is that the user records on the phone, and the system stores the recording result in the user's personal music database, and the user can choose from the personal music database when selecting a ringtone in the future; One is that the user can select different music files on the website and directly upload them through the website, and the system will check the sound content and convert the format, and store it in the user's personal music database. None of this affects the spirit and scope of the present invention.

Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein, and without departing from the spirit and scope of the invention as defined by the appended claims.
