Description

Method and system for realizing telephone call ring back tone replacement on mobile phone intelligent network

Technical Field

The invention relates to a method and a system for realizing the replacement of a telephone call ring back tone on a mobile phone intelligent network, in particular to a method and a system for realizing the replacement service of the telephone call ring back tone on the mobile phone intelligent network through an independent call ring back tone replacement device according to a personalized ring back tone replacement scheme customized by a mobile communication user in advance, belonging to the technical field of mobile communication.

Background

The number of mobile communication users is rapidly increasing; at present, the number of users owned by one operator of China Mobile Telecommunications group company reaches as much as 1.7 hundred million. With the increase of the number of mobile communication users, new technologies and new services of mobile communication are changing day by day and emerge endlessly.

In recent years, the application of Customized Applications for Mobile network enhanced logic (CAMEL) in the Mobile phone intelligent network (hereinafter referred to as intelligent network) technology in the global scope has been rapidly developed, which brings great value-added services to users and huge business opportunities to numerous network operators and equipment manufacturers. The intelligent network technology separates the service call exchange function and service control of the network thoroughly, and makes the service execution environment independent of the provision of specific services, thereby achieving the purpose of providing services in a telecommunication network in a centralized and rapid manner. The intelligent network not only can provide value-added services, but also has an architecture which is very suitable for a plurality of non-value-added services (such as number portability services and the like) which are necessary for the opening of the telecommunication market. The advent of intelligent network technology has fundamentally changed the traditional way in which telecommunications networks provide services. At present, only in china, a mobile Intelligent Network implemented on a Global System for mobile communication (GSM) Network by using the CAMEL standard and a Wireless Intelligent Network implemented on a CDMA (Code division multiple Access) Network by using WIN (Wireless Intelligent Network) specification have been established. Currently, research and attempts are being made in the third generation of intelligent networks for mobile communication, broadband intelligent networks, and the combination of the Internet and intelligent networks.

Although intelligent network technology has some variations due to the different network formations, the implementation of intelligent network key systems is roughly the same. Therefore, when the intelligent network is referred to later, it is no longer a column, but is collectively referred to as the intelligent network.

The telephone communications technology and services have changed greatly in all respects from the invention of the telephone to the hundred years experienced today, but the telephone ringback tones have not changed much, and are basically "beep … … beep" tones. The ring-back tone of a mobile phone integrated with the essence of modern technology still maintains the traditional and monotonous tone ring-back tone.

In the age that the industry, business and service industry are full of individuation nowadays, mobile communication has become a typical channel for people to contact with the society; the color is given to the channel, and different personalized services are provided for each person, so that the service development trend is consistent with the pursuit of personalized characteristics in the modern times. The aim of changing the traditional tone ring back tone into colorful voice and music ring back tone and providing the personalized service which can self-select or self-compile ring back tone for the user conforms to the development trend of the mobile communication service.

The ringback tone replacement service is a value added telecommunication service customized by the called party of a telephone call to provide a pleasant tone or greeting (ringback tone replacement scheme). This service can provide a personalized presentation to the called subscriber, which can change the monotonous ringback tone provided in the prior art that the calling party of a telephone call hears before the called subscriber responds to the call.

Referring to fig. 1, a called subscriber 1 presets a personalized ring back tone in advance, and when a calling party 2 calls the called subscriber 1, a mobile communication system sends a ringing instruction to the called subscriber 1; meanwhile, the personalized ring back tone preset by the called user 1 is used for replacing the original ring back tone, so that the calling party hears the personalized ring back tone preset by the called user 1 before the called user 1 answers the call.

The ring back tone replacement service changes the uniform ring back tone, and can make the user express the personality. The user can customize greeting words and ring-back tones according to the preferences of the user, friends, colleagues and upper levels, so that the service initiator (calling party) can hear rich and colorful, novel and personalized ring-back tones.

The ring back tone replacement service transmits a ring tone, music or a greeting selected by a user to a telephone (calling telephone) dialing the user through the mobile communication system as a ring back tone when the called user does not answer. However, because a large number of mobile phones of traveling users are in a roaming state, the ring back tone replacement service is opened in a troublesome technical problem, which is mainly represented as: when the called subscriber leaves its registered place and enters into roaming state, the operator will not be able to provide the subscriber with ringback tone replacement service in roaming state because the mobile communication system of the unregistered place does not store the ringback tone information set by the subscriber in advance (doing so would waste a lot of resources). It is obvious that if the ringback tone information set by a subscriber cannot follow the subscriber for roaming, the ringback tone replacement service obtained by the subscriber can be implemented only at the location where the subscriber is registered, but not at a different location.

For the above problems, the company has filed the following applications: 02148704.9, the corresponding solutions are given in the chinese patent: the ring back tone replacing system of the called subscriber roaming place applies for the ring back tone replacing resource data of the ring back tone replacing system of the called subscriber registration place after acquiring the roaming event of the called subscriber; the ring back tone replacement system of the called subscriber registration contract place copies the ring back tone replacement resource data thereof into the ring back tone replacement system of the roaming place; then the ring back tone replacing system of the called user roaming place provides the service of ring back tone replacement for the called user.

The technical scheme solves the problem of the following roaming of the ring back tone replacement service, but the technical scheme is based on the premise that the area where the called user is located acquires the ring back tone replacement data. Since the ringback tone replacement data is basically sound data, the above-described technical solution may result in a large amount of data transmission. Moreover, whenever the called subscriber arrives, the ringback tone replacement system at the place copies the ringback tone replacement data of the called subscriber to the local, which also puts storage pressure on the local system. The main reasons for the above problems are: the ring back tone replacement is realized by a ring back tone replacement system at the location of the called subscriber.

Through analysis, the following results can be found: whether the called user is roaming or not, the replaced ring back tone is finally sent to the calling party; that is to say: the ring back tone replacement is only related to the location of the calling party and the subscription place of the called party, and is not related to whether the called party roams or not; therefore, although the above technical solution enables the called user to still obtain the service of replacing the ringback tone when roaming, a large amount of storage resources are required. Moreover, when the amount of the ringback tone replacement data is large, the technical scheme can only provide the ringback tone replacement service for the called subscriber in a delayed mode.

example 1

Method for realizing ring back tone replacing service on intelligent network

The method for realizing the ring back tone replacement service is realized by utilizing the service control capability of an intelligent network and assisting a corresponding intelligent peripheral system (providing an audio signal for replacing the ring back tone) on the basis of the existing intelligent network.

Referring to fig. 2 and fig. 4, the embodiment implements the ringback tone replacement service on GSM mobile intelligent network CAMEL. Wherein: on the basis of GSM mobile intelligent network CAMEL, in order to implement the ring back tone replacement service, an intelligent network element-PRBT-IP can be added in the network to provide the ring back tone playing of the ring back tone replacement service, the personal customization of the ring back tone replacement scheme, and the like, and the intelligent network element-PRBT-IP can be independently arranged and can also be combined with a similar intelligent peripheral system on the intelligent network.

While increasing PRBT-IP, certain upgrading of the network is required.

A corresponding service flag (flag), CAMEL Subscription Information (CSI), needs to be set in the Home Location Register (HLR) of the subscriber.

When the mobile user carries out location updating and corresponding necessary conditions, the HLR sends the CAMEL subscription information to a Visitor Location Register (VLR). So that MSC/VLR can obtain the correspondent information of ring-back tone replacement service of user.

Mobile switching center/visitor location register/service switching point (MSC/VLR/SSP) and gateway mobile switching center/service switching point (GMSC/SSP) require the addition of corresponding origination and processing flow for the ringback tone replacement service. MSC/VLR/SSP and GMSC/SSP are provided with the ability of supporting the ring back tone replacement service.

The method for implementing the ringback tone replacement service by using a mobile subscriber applying for the ringback tone replacement service as a subscriber a, calling the subscriber as a subscriber B (which may be a mobile phone subscriber or a fixed phone subscriber), and using the subscriber a as a called subscriber is described as follows:

user B initiates a telephone call with user A as the called party;

when receiving the call connection of user A as called, mobile originating MSC/VLR/SSP or GMSC/SSP inquires user A service information and roaming number in user A's Home Location Register (HLR);

if the user A is not CAMEL subscriber of the intelligent network service, the processing is continued according to the common telephone;

if the user A is a subscriber of the intelligent network ring back tone replacement service, the mobile originating MSC/VLR/SSP or GMSC/SSP will trigger the ring back tone replacement service according to the CAMEL subscription information, send IDP information to the home gsmSCF of the user A and request to start the ring back tone replacement service;

the attribution g smSCF of the user A processes the request and sends the ring tone replacement service control information back to the mobile originating MSC/VLR/SSP or GMSC/SSP; if the user A belongs to the PRBT-IP information for storing the ring back tone resource of the ring back tone replacement scheme customized by the user A;

under the control of gsmSCF, MSC/VLR/SSP or GMSC/SSP at mobile originating end processes call continuously according to the signaling flow of ring back tone replacement service;

the mobile originating MSC/VLR/SSP or GMSC/SSP continues to continue the call according to the roaming number of the user A until reaching the terminal landing exchange of the user A;

the terminal landing exchange office of the user A inquires the called state, if the user A is idle, the terminal landing exchange office of the user A sends a ringing command to the user A, the user A starts ringing, and the terminal landing exchange office of the user A sends a common ring back tone to a calling user;

the mobile originating MSC/VLR/SSP or GMSC/SSP does not connect the terminal landing exchange office where the user A is located to send the common ring back tone to the calling user, and carries out the ring back tone replacement service processing;

the mobile originating MSC/VLR/SSP or GMSC/SSP initiates a call request of a ring back tone replacement service to the home PRBT-IP of the user A according to the information of the home PRBT-IP provided by the home gsmSCF of the user A, and provides the telephone number information of the user A and the user B;

the PRBT-IP receives the call request and extracts the telephone number information according to the user A and the user B;

the PRBT-IP inquires a database of the PRBT-IP system according to the telephone number information of the user A, authenticates the user A and judges whether the user A is a legal user of the system;

for calls that cannot pass authentication, the PRBT-IP system cannot provide ringback tone replacement service, reject this ringback tone replacement service call, or send a general ringback tone signal (music or voice prompt);

for the call passing the authentication, the PRBT-IP system inquires a ring-back tone replacement scheme customized by the user according to the user information data of the user under the control of a control node CN, and provides audio signals such as voice, music and the like to a calling user to replace the ring-back tone of the common beep tone according to the ring-back tone replacement scheme customized by the user;

if the connection between the mobile originating MSC/VLR/SSP or GMSC/SSP and PRBT-IP system fails, if the call is rejected by the PRBT-IP system (authentication is not passed), the trunk line is busy (congestion), etc., in order to ensure that the telephone call service is not affected by the value-added service, the mobile originating MSC/VLR/SSP or GMSC/SSP resumes providing the common ring back tone to the calling user so as to complete the telephone call;

when a mobile called user who is providing a ring back tone replacement service call answers (answers), a mobile originating MSC/VLR/SSP or GMSC/SSP connects a call path between the calling and called users according to a normal telephone call and sends called response information to a front switchboard (if the called party exists), so that the calling and the called users enter a telephone conversation stage, and then the call providing a customized ring back tone signal between the calling and called users and a PRBT-IP system is removed;

after receiving the call removal information, the PRBT-IP system stops playing the ring-back tone signal and removes the call connection release resource; thus, the service of the ringback tone replacement service is completed.

In the case of the example 2, the following examples are given,

individual ring back tone replacement service independent intelligent peripheral (PRBT-IP) system

In the invention, in order to realize the ring back tone replacement service based on the intelligent network, a PRBT-IP system is required to be arranged in the intelligent network, and the system is used as an independent intelligent peripheral to complete the ring back tone replacement operation under the control and management of the intelligent network.
