Detailed Description
The system diagram of the background sound service shown in fig. 1 includes at least a switch and a background sound service platform on the network side. The switch may be an SSP/MSC or the like for enabling access and connection of the subscriber call. The background sound service platform is used for storing background sound data and providing background sound playing; and the three-party call capability is provided, and the background sound service platform is used as one party to be added into the call of the calling party and the called party. The background sound service platform can be realized by the exchanger and an enhanced intelligent peripheral (AIP), wherein the exchanger realizes three-party communication, and the AIP realizes the storage and playing of background sound data. The background sound service platform can also be implemented solely by AIP with three-party telephony capability. The AIP may be an Intelligent Peripheral (IP), and will not be described below.
The background sound service platform also allows the user to access and manage the sound effect files of the background sound service. For example, a content provider is allowed to access a background sound service platform through Web and other modes, and a background sound effect file is uploaded and submitted; allowing a network operator to approve and load the sound effect files uploaded by the content provider into a background sound service platform; allowing the end user to set and manage a personal sound effect library and to apply for or log out a background sound service.
The method for adding the background sound service in the call mainly comprises the following steps: a calling user calls a called user; after receiving the background sound, the network side triggers the background sound service according to a preset triggering mechanism, calls a background sound service platform, establishes a three-way call between the background sound service platform and a calling party and a called party, and plays the background sound by the background sound service platform; the network side selects background sound or adjusts the volume of the background sound according to the key information uploaded by the user triggering the service; and when the call is finished, the network side releases the connection of the three parties of the call.
Wherein, the triggering mechanism may be: triggering according to a service access code carried by a calling user when calling; the following steps can be also included: and triggering by the calling party or the called party according to the preset background voice service subscription information of the calling party or the called party. The background sound service triggered by the calling party and the background sound service triggered by the called party can be respectively carried out according to the triggering of the calling party and the called party.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by the following embodiments.
Fig. 2 is a schematic diagram of a first embodiment of implementing the background sound service system, in which the background sound service platform is implemented by an exchange and an AIP, where the exchange is the MSCa. The switch is used for realizing a three-party call function and realizing three-party calls of a calling party, a called party and a background sound service platform; the AIP is used to play background sounds during the calling and called calls. Referring to the flowchart of the first embodiment of implementing the background sound service shown in fig. 3, the details are described by taking an example that a calling subscriber a implements the background sound service, in this example, a switch is an MSC, and a service access code for triggering the background sound service needs to be set on the switch in advance, and the method further includes the following steps:
step 301: calling user a dials the service access code + called number b and reports MSCa.
Step 302-304: MSCa receives the information sent by user a, routes the call to AIP according to the service access code, initiates the call to AIP, and establishes connection from MACa to AIP after receiving the off-hook answer signal (ANM) returned by AIP, wherein MSCa sends the called number b to AIP through IAI information. In this process, the AIP responds automatically, similar to an end user.
Step 305: the AIP sends Call Progress Message (CPG) information to the MSCa, and instructs the MSCa to maintain the Call path from the calling user a to the AIP which is established at this time.
Step 306-311: and the AIP initiates a call to the user b through the MSCa according to the received called number b, and establishes a speech path from the AIP to the called user b after the called user b picks up the phone.
Step 312: the AIP sends CPG information to MSCa to indicate the MSCa to set two speech paths of a user a-MSCa-AIP and a user b-MSCb-MSCa-AIP as a three-party conference mode, and the MSCa establishes three-party conversation of a calling user a, a called user b and the AIP. At this time, the calling user a and the called user b can make a call, and the AIP plays the default background sound.
Step 313: the AIP monitors the key information reported from the calling user a, and plays the corresponding background sound effect according to the received key information; or adjust the sound volume of the playing. For example, the calling user presses the number keys 0-9, and the system receives and plays the corresponding background sound effect. The calling user presses the function #/, and the system increases/decreases the volume of the background sound effect after receiving the signal. As will be understood, the AIP may also monitor the key information reported from the called user b, and play the corresponding background sound effect; or adjust the sound volume of the playing.
It can be seen that, in this example, the three-party call of the calling subscriber, the called subscriber and the AIP is established on the originating exchanger, so that the function of adding the background sound played by the AIP in the calling and called call process is realized, and the AIP can play the corresponding background sound effect according to the key of the subscriber. When the call is finished and a certain user hangs up, the MSCa finishes the three-party call and releases the established connection.
Fig. 4 is a schematic diagram showing a second embodiment of implementing the background sound service system, in which the background sound service platform is implemented by AIP alone with a three-party call capability. When the mode is used, the method is the same as the method for realizing the three-party call by the existing mature conference telephone system, namely, the three-party call is realized by establishing a multi-party call meeting place through AIP. Referring to the flowchart of the second embodiment of implementing the background sound service shown in fig. 5, the calling background sound service is taken as an example for explanation. Wherein, the switch is an MSC in this example, and a service access code for triggering the background sound service needs to be set on the switch in advance, and the method further includes the following steps:
step 501: calling user a dials service access code + called number b, and reports MSCa.
Step 502-503: MSCa receives the information sent by user a, routes the call to AIP according to the access code, and sends IAM information to AIP, wherein the information contains called number b and AIP loopback address full (ACM) information.
Step 504: the AIP establishes a meeting place of three-party call and adds the calling subscriber a to the meeting place. For the procedure of establishing the meeting place by AIP, reference may be made to the technical specification of AIP/IP, or to the implementation technology of multipoint conference, and will not be described here.
Step 505-: the AIP initiates a call to the user b through the MSCb according to the received called number b, establishes the speech path connection from the AIP to the called user b after the called user b goes off the phone, and adds the called user b into the established meeting place. And the AIP also adds itself as a third party to the established meeting place to realize the three-party call with the calling user a and the called user b. At this time, the calling user a and the called user b can make a call, and the AIP plays the default background sound.
Step 510 is the same as step 313 and will not be described in detail. When the call is finished and a user hangs up, the AIP finishes the three-party call, releases the established connection and finishes the established meeting place.
All the above descriptions are in a mode of dialing a service access code to trigger a background sound service, and in addition, a mode of service subscription information triggering can be used to trigger the background sound service. When the subscription information is used for triggering, the user does not need to dial the service access code, and can directly dial the called number. Referring to fig. 6, a schematic diagram of a third embodiment of a system for implementing background sound service, which can implement a subscription information triggering manner, in comparison with the above-mentioned system structure for implementing background sound service, a network side needs to add an SCP, store background sound service logic on the SCP, and the SCP completes issuing the background sound service logic and exchanges information with an exchange to affect call processing of the exchange. In addition, the subscription information of the user using the background voice service needs to be registered in advance in the switch or the location home register (HLR), and refer to the flowchart of the third embodiment for implementing the background voice service shown in fig. 7, where the switch is an MSC and the calling party a is a registered user. The method comprises the following steps:
step 701: and (4) the registered calling subscriber a dials the called number b and reports the MSCa.
Step 702-: MSCa obtains the subscription information of user from HLR, triggers the background sound service according to the subscription information of user a, reports SCP, SCP issues the operation of connection (CONNECT) to MSCa according to the recorded service logic of background sound, and instructs MSCa to CONNECT the calling of calling user a to AIP;
In addition, when the service is triggered by using the subscription mode, it is understood by a general technician that a called party triggering mode may also be adopted, referring to a flow chart of the called party triggering implementation background sound service shown in fig. 8, the background sound service is triggered at the MSCa according to the subscription information corresponding to the received called number, and the flow is similar to the calling triggering flow, and details are not described here.
The above solution for implementing three-way telephony capability by a switch has the advantage of no speech detour. The disadvantage is that for the service operator, there is a charging problem, and there may be some modification workload; and the existing network switch has limited three-party call resources, the switch is used for realizing the service that the three-party call cannot support larger traffic, if the larger traffic needs to be supported, the switch needs to be modified, and the cost and the workload are larger. For the scheme of realizing three-party call by AIP, the advantage lies in that a new entity is directly superposed on the existing network, the cost and the workload are small, and a large telephone traffic can be supported; at the worst, there is speech detour, i.e. the calling and called calls need to be connected through AIP.
The network operator can select different schemes according to the requirement by combining the current network situation. Generally speaking, in the initial stage of service development, under the condition that the telephone traffic is not very large, the three-party call can be realized by AIP, the service can be quickly opened only by adding a background sound service platform on the current network, and the market can be quickly developed. After the market is mature, the exchange can be considered to realize the three-party call, and the exchange is modified to support the three-party call with large telephone traffic.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
