Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a method and device for initiating calls to both ends of a calling party and a called party by a privacy number. Background Art

[0002] With the continuous development of communication technology, privacy protection has become an important issue that users and enterprises are increasingly concerned about. In various business scenarios, such as online car-hailing, express delivery, and food delivery services, it is particularly important to protect users' real numbers from being leaked.

[0003] At present, the privacy number model widely used in the market is mainly the AXB calling method, that is, the calling and called numbers AB are bound to the middle number X to achieve the purpose of hiding the real numbers of both parties for the call. However, this method is more dependent on the calling and called party to initiate the call, which means that the initiating party has to bear all the call costs. This not only increases the operating costs for many corporate users, but also reduces the user experience to a certain extent and limits the flexibility and efficiency of communication. In addition, there may be outbound call requests from unreported numbers, which to a certain extent affects the normal operation of the business and may reduce the security and privacy protection of the communication process. Summary of the invention

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Combine the following Figures 1 to 9 The present invention describes a method and device for initiating calls to both the calling and called parties by a privacy number.

[0052] like Figure 1 As shown, in one embodiment, a method for initiating a call to both ends of a calling party and a called party by a privacy number is applied to a privacy communication platform, and includes the following steps:

[0053] Step S110, obtaining the calling and called numbers, reviewing the calling and called numbers, and storing the calling and called numbers in the reported number pool after passing the review. The calling and called numbers include the calling number and the called number.

[0054] Specifically, the privacy communication platform obtains the calling number and the called number, and reviews the calling number and the called number. After the review is passed, the calling number and the called number are stored in the reported number pool.

[0055] Combination Figure 2As shown, in a specific embodiment, the method provided by the present invention for initiating calls to both the calling and called parties by a privacy number first requires the reporting and review of the number. During the reporting and review process of the number, the enterprise user needs to submit the AB numbers (i.e., the calling number and the called number) planned for communication to the privacy communication platform for reporting. The privacy communication platform will review these numbers to ensure that the numbers comply with relevant laws and regulations and platform regulations, such as the legitimacy of the numbers and whether they have been reported by other customers.

[0056] In this embodiment, the corporate user submits a number reporting request through the interface or management interface provided by the privacy communication platform, including number information, corporate qualification certificate and other necessary materials. The privacy communication platform automatically or manually reviews the reporting request and adds the number to the reported number pool after the review is passed.

[0057] Step S120, receiving a double call communication request from the user terminal through the HTTP protocol, and in response to the double call communication request, initiating calls to the calling number and the called number respectively to establish a first call connection channel with the calling number and a second call connection channel with the called number.

[0058] Specifically, the privacy communication platform receives a double-call communication request from the user terminal through the HTTP protocol, and initiates calls to the calling number and the called number respectively in response to the double-call communication request to establish independent call connection channels for the calling number and the called number, namely, the first call connection channel and the second call connection channel.

[0059] Combination Figure 2 As shown, in a specific embodiment, the method provided by the present invention for initiating calls to both ends of the calling and called parties by a privacy number, after the calling and called numbers are stored in the reported number pool, needs to be called and parameter configuration is performed. When an enterprise user needs to initiate a double call communication, the communication process is triggered by calling the API interface provided by the privacy communication platform. When calling the interface, the corresponding parameters need to be configured, such as AB numbers, call duration, call time, etc. Enterprise users write code or scripts to call the API according to business needs, set appropriate parameters, and send the request to the privacy communication platform through HTTP requests or other protocols.

[0060] Step S130, after the calling number and the called number are connected, the first call connection channel is bridged with the second call connection channel to establish a third call connection channel between the calling number and the called number.

[0061] Specifically, after the calling number and the called number are connected respectively, the first call connection channel and the second call connection channel are bridged to establish a third call connection channel between the calling number and the called number to achieve communication between the calling number and the called number.

[0062] Combination Figure 2 As shown, in a specific embodiment, the present invention provides a method for initiating calls to both ends of the called party by a privacy number. After receiving the request, the privacy communication platform establishes and connects the call. After receiving the API call request from the enterprise user, the privacy communication platform will initiate calls to the AB numbers respectively. The privacy communication platform establishes two independent call connections through its own communication resources or a third-party communication service provider.

[0063] In this embodiment, the privacy communication platform uses AB numbers in the reported number pool as call targets and sends call requests to these numbers through the telecommunications network. When the users of AB numbers answer the call, the privacy communication platform bridges the two call connections to enable a call between AB.

[0064] Step S140, using fast Fourier transform and short-time energy analysis technology to monitor the spectrum distribution and energy changes of the call audio signal between the calling number and the called number in real time, so as to dynamically adjust the audio codec parameters based on the monitoring results, and identify and suppress interference noise through a deep learning algorithm.

[0065] Specifically, the privacy communication platform uses fast Fourier transform and short-time energy analysis technology to monitor the spectrum distribution and energy changes of the call audio signal between the calling number and the called number in real time, and dynamically adjusts the audio codec parameters based on the monitoring results, as well as identifies and suppresses interference noise through deep learning algorithms.

[0066] Combination Figure 2 As shown, in a specific embodiment, the present invention provides a method for initiating calls to both ends of the caller and the called party by a privacy number. After the two parties AB establish communication, the call process needs to be monitored. During the call between the two parties AB, the privacy communication platform will monitor the call in real time to ensure the quality and stability of the call. At the same time, the privacy communication platform will also record detailed information of the call, such as call duration, call quality score, etc. The privacy communication platform uses advanced communication technology and algorithms to monitor and optimize the signal quality, network delay, etc. during the call in real time, and store the detailed information of the call in the database for subsequent query and analysis by corporate customers.

[0067] In this embodiment, in order to ensure the call quality and stability during the call process and monitoring stage of the double call mode, a series of innovative communication technologies and algorithms are introduced. These technologies can not only monitor the call process in a refined manner, but also automatically adjust and optimize the call parameters based on the monitoring results, thereby significantly improving the user experience. Fast Fourier transform (FFT) combined with short-time energy analysis is used to monitor the spectrum distribution and energy changes of the audio signals of both parties in the call in real time, and identify the voice segment, silence segment and possible noise interference. The parameters of the audio codec, such as bit rate, sampling rate, etc., are dynamically adjusted according to the monitoring results. For example, when the voice clarity requirement is high, the bit rate is increased to improve the sound quality. When the signal quality decreases or the bandwidth is limited, it automatically switches to a lower complexity codec to keep the call smooth. In addition, deep learning algorithms can also be used to identify and suppress background noise to enhance the recognition of voice signals.

[0068] In this embodiment, ICMP (Internet Control Protocol) echo request (Ping) and TCP connection test are used, combined with historical communication data and network traffic models, to predict the communication network congestion in the current and future period. According to the prediction results, the best communication path is intelligently selected. When a potential network congestion point is detected, it automatically switches to a backup communication line or adjusts the routing strategy to reduce delays and packet loss. In the double-call scenario of privacy communication, since privacy communication is connected to the operator's core network through multiple provincial nodes across the country, the optimal communication path at that time can be selected based on the monitoring of the corresponding multiple node network paths. In addition, a load balancing strategy is implemented among multiple available communication resources to ensure call quality while optimizing the utilization of overall network resources.

[0069] In this embodiment, advanced adaptive filter technology (such as NLMS and RLS algorithms) can also be used, combined with deep learning algorithms to extract features, to accurately identify and eliminate echoes in calls, especially multipath echoes in complex environments. For example, speech recognition technology and time-frequency analysis can be used to accurately determine whether both parties are speaking at the same time. In the case of double talk, the voices of both parties are balanced to avoid mutual interference by adjusting the volume gain and using vocoder compression. According to the double talk detection results, the parameters of the echo canceller are adjusted in real time to ensure that the best effect can be achieved in different call scenarios.

[0070] In this embodiment, when the call between AB ends, the privacy communication platform will send a call end notification to the enterprise user and calculate the call fee. The enterprise user needs to pay the call fee in the agreed method and time. The privacy communication platform calculates the call fee based on the detailed information of the call (such as call duration, rate, etc.) and generates a fee list. The enterprise user pays the fee through the payment interface provided by the privacy communication platform or offline channels. In addition, after receiving the fee, the privacy communication platform will update the account balance of the enterprise customer or generate the corresponding invoice and bill.

[0071] In this embodiment, the privacy communication platform also provides data statistics and analysis functions to help enterprise users understand communication usage and optimize communication strategies. The privacy communication platform generates various statistical reports and charts based on the stored call data, such as call duration distribution, cost consumption, etc. Enterprise users can query these call data through the management interface or API interface of the privacy communication platform and conduct in-depth analysis.

[0072] In the above method of initiating calls to both ends of the calling and called parties by the privacy number, the privacy communication platform obtains the calling and called numbers, reviews the calling and called numbers, and stores the calling and called numbers in the reported number pool after the review is passed. Then, the double call communication request from the user end is received through the HTTP protocol, and in response to the double call communication request, calls are initiated to the calling number and the called number respectively to establish a call connection channel with the calling number and a call connection channel with the called number. Subsequently, after the calling number and the called number are connected, the two call connection channels are bridged to establish a call connection channel between the calling number and the called number. During the call between the calling and called numbers, the fast Fourier transform and short-time energy analysis technology are used to monitor the spectrum distribution and energy changes of the call audio signal between the calling number and the called number in real time, so as to dynamically adjust the audio codec parameters according to the monitoring results, and identify and suppress interference noise through deep learning algorithms to improve the call quality and ensure the stability of the call process. This method initiates two calls to the privacy communication platform at the same time through the enterprise user end, connecting the calling and called users A and B respectively, so that both parties can talk without exposing their real numbers. At the same time, the enterprise bears the main call costs, which reduces the communication costs of the calling and called users to a certain extent, and improves the communication efficiency and the security of the communication process.

[0073] like Figure 3 As shown, in one embodiment, the method provided by the present invention for initiating a call to both ends of a calling party and a called party by a privacy number, obtaining the calling party and the called party numbers, reviewing the calling party and the called party numbers, and storing the calling party and the called party numbers in a reported number pool after the review is passed, specifically includes the following steps:

[0074] Step S112, reviewing the calling number and the called number to determine whether the calling number and the called number meet the preset regulations of the privacy communication platform.

[0075] Step S114, determine whether the calling number and the called number have passed the review, and store the calling number and the called number in a reported number pool.

[0076] Specifically, when the judgment result in step S112 is that the calling number and the called number meet the preset regulations of the privacy communication platform, the calling number and the called number are determined to have passed the review, and the passed calling number and the called number are stored in the reported number pool.

[0077] Step S116, determining that the calling number and the called number have failed the review.

[0078] Specifically, when the judgment result in step S112 is that the calling number and the called number do not meet the preset regulations of the privacy communication platform, it is determined that the calling number and the called number have failed the review.

[0079] Among them, the preset regulations include the format requirements of the calling number and the called number and whether to report them repeatedly. If the calling number or the called number already exists in the reported number pool, the review will not pass.

[0080] like Figure 4 As shown, in one embodiment, the method for initiating calls to both the calling and called ends by a privacy number provided by the present invention receives a double call communication request from a user end through the HTTP protocol, and initiates calls to the calling number and the called number respectively in response to the double call communication request to establish a first call connection channel with the calling number and a second call connection channel with the called number, which includes the following steps:

[0081] Step S410, obtaining a code or script for calling an API written according to the business requirements of the user end, and setting configuration parameters, wherein the configuration parameters include the calling number and the called number, the call duration, and the call time.

[0082] Step S420, when the user terminal initiates a double call communication request, the double call communication process is triggered by calling the API interface provided by the privacy communication platform.

[0086] The dual call communication request includes an API call request and a call request.

[0087] like Figure 6 As shown, in one embodiment, the method provided by the present invention for initiating calls to both ends of the calling and called by a privacy number uses fast Fourier transform and short-time energy analysis technology to monitor the spectrum distribution and energy changes of the call audio signal between the calling number and the called number in real time, so as to dynamically adjust the audio codec parameters based on the monitoring results, and identify and suppress interference noise through a deep learning algorithm, which specifically includes the following steps:

[0088] Step S142, based on the third call connection channel, obtain the call audio signal between the calling number and the called number, and monitor the spectrum distribution and energy change of the call audio signal in real time through fast Fourier transform and short-time energy analysis technology to obtain the monitoring result.

[0089] Step S144, adjusting the audio codec parameters according to the monitoring results, the audio codec parameters at least including the bit rate and the sampling rate, so as to improve the sound quality of the speech segment, and switching the audio codec when the signal quality is degraded or the bandwidth is limited.
