"Tagya, a web anchor from Bangalore, India, opened the social software on her phone and soon received a video matching request from a strange user. After receiving the order, the two sides chatted for nearly half an hour. Tagya can get a share of the user's payment." This is a very popular 1v1 social scene in Southeast Asia, India, the Middle East, Europe and the United States. With social efficiency, freshness, strong cash ability and other factors, 1v1 social is becoming the most popular social scene.

The success of 1v1 Social in the overseas market, on the one hand, is due to the fact that the user side is "suitable for all ages". Whether it is Western countries such as Europe and the United States, which are more open-minded, or some overseas regions with less developed education, 1V1 social networking with strong social and private nature can be generally loved by local users. Secondly, on the platform side, 1v1 social scene integration is fast, online is fast, cash ability is strong, through paid calls and gift rewards can bring effective benefits for enterprises, but also attracted more and more attention of social platforms.

With the popularity of 1v1 social networking, it also extends the game of transferring live shows to 1v1: during the live broadcast, viewers can apply for a 1v1 call to the VJ for a fee. The original studio is not closed but there is no picture. After the two parties end the 1v1 call, the VJ's picture will be restored in the room. The transition from show to 1v1 not only enriches the play of live scenes, but also provides a new revenue method for show anchors to reward gifts. The platform is billed according to the number of minutes of 1v1 calls, and the anchors can get a certain share.

Whether it is pure 1v1 social networking or show-to-1v1, billing can only be started when the connection is successful, in which the connection rate is an important indicator that affects the conversion rate of payment. From the perspective of user psychology, once a user fails to connect 4-5 seconds or more after initiating a call request to the VJ or the VJ agrees, the user will gradually lose the patience to wait, and it is likely to exit the call, resulting in the failure of the order, which in turn affects the revenue of the platform. Therefore, the improvement of the access rate will further help enterprises to increase revenue.

So what are the factors that affect the connection rate in 1v1 social scenarios? From the time the user initiates a call to seeing the first frame of the other party, the service connection rate, network quality and connection time will all affect the connection rate, and the service connection rate and network quality are greatly affected by objective conditions. For example, after the user initiates a call, the VJ does not see it for a few seconds, or the VJ does not want to answer it at all after seeing the call. These all belong to the category of service connection rate. Developers are required to focus on polishing business logic. But in addition, the time-consuming audio and video connection and the arrival rate of message transmission are still the key technical directions that enterprises need to focus on.

In this regard, with the accumulation of many years of technical experience and continuous polishing with customers in overseas markets, Soundnet already has a set of mature 1v1 global second connection best practices, which reduces the integration difficulty in the form of 1v1 scene API, helps customers directly avoid the error-prone points of second connection integration, and can achieve that the best connection time is less than 600ms. At the same time, the audio network solution can make the user's connection time experience unaware. It will bring great help to the improvement of the connection rate and the revenue of customers.

RTM+RTC parallel start-up takes as little time as 600ms

In the 1v1 social scenario, the user initiates a call to see the first frame of the other party, which requires signaling control and RTC transmission, in which signaling is used to achieve low-delay message transmission and status monitoring between paying users and VJs to ensure consistent synchronization. Therefore, the optimal timing of signaling and RTC access is the key factor affecting the connection time.

At present, the traditional 1v1 social solution in the industry is to start signaling and RTC serially in the underlying architecture, and the process is as follows: after a paid user initiates a call, it is communicated to the VJ through signaling, and then the VJ clicks to agree, and then communicates the status back to the paying client through signaling, and then enters the process of joining the RTC channel to start the subscription stream. The serial of signaling and RTC leads to the increase of connection time.

The 1v1 scene scheme of acoustic network not only supports the best practice of tripartite mature signaling and RTC integration, but also supports the scheme that acoustic network RTM replaces traditional signaling. The RTM and RTC interfaces are encapsulated through scene API, and the calling time sequence of the interface is defined in best practice, so that customers can achieve the fastest second connection effect. To put it simply, the audio network implements the parallel startup of RTM and RTC on the underlying architecture. Immediately after the user initiates a call, the RTC channel is loaded in advance and the video stream is pronounced, the action of the first frame is pre-loaded, saving the time of adding the channel and sending the stream. The VJ subscribes to the video stream immediately after the VJ agrees, and the VJ takes less than 600ms to get the picture in seconds.

Through the two architecture diagrams below, we can see more intuitively how the optimized 1v1 infrastructure can effectively reduce the connection time.

Scene solution of industry 1v1 with high ease of use and high perfection

In addition to the fact that the minimum connection time is lower than that of 600ms, the sound network 1v1 scene solution has multiple core advantages:

1. The solution is more perfect, and the best practices of dealing with corner case are fully considered.

In the interworking of 1v1, Voice Network integrates the processing logic of the international mainstream social software in the 1v1 scenario, fully taking into account some extreme cases of corner case. For example, when a user is in a 1v1 video call, if he opens another APP,1v1 call, it will automatically switch to the background, and the audio stream will remain normal, and the user and the VJ can continue to communicate. For example, when the user opens another APP,1v1 call, it will automatically switch to the background, and the audio stream will remain normal, and the user and the VJ can continue to communicate.

In addition, at the network level, the sound network scheme also fully takes into account the different network environment. For example, after the network is disconnected, the audio and video interconnection is interrupted and stays at the last frame. After the network is restored in a short period of time, the transition is smooth and the audio and video interconnection is normal. During the WiFi network handover, the transition will be smooth, and the audio / video interconnection will remain normal.

2. High ease of use: fast access with only a few core API

In order to realize the effect integration of 1v1 in seconds, developers need to fully understand the business logic, signaling integration logic, server processing and RTC integration logic, and skillfully and carefully deal with every detail call timing and method in order to ensure the final second turn-on effect and optimal performance consumption. The requirements for developers' detail control are very high, so many customers often encounter "integration is not difficult." But the painful situation that the effect is difficult to achieve.

Based on the best practices summarized by 1v1 customers around the world, Soundnet provides 1v1 scene API that supports rapid integration by developers. Customers do not need to know the detailed logic of signaling and RTC business logic, but only need to call a few encapsulated interfaces to quickly achieve the effect of connecting in seconds.

3. Overseas underlying network optimization and weak network guarantee

In overseas areas, the level of network infrastructure in many countries is uneven, how to reasonably match and optimize the local network environment is very important for overseas enterprises. In 1v1 social communication, the complex network environment will have a great impact on the connection rate and time-consuming.

In this regard, on the one hand, the sound network uses network coverage quality evaluation standards to guide the construction of global edge basic resources, improve network coverage, adjust access strategies, optimize key indicators, and enhance user experience. On the other hand, Sound Network also has a sound global supplier management system, using public clouds, private clouds and other resources, covering 200 + countries and regions, especially for Southeast Asia, the Middle East, North America and domestic small and medium-sized cities, small operators to do network optimization.

Take India as an example. India has a vast territory, with 28 states, and the digital consumer population is the second largest in the world, second only to China. However, the deficiency of communication infrastructure in India is more obvious. India has hundreds of network operators, and the network relationship is complex, with insufficient number of base stations, limited frequency band, insufficient data capacity and other problems, resulting in poor network experience of users. In order to ensure that the user access flammable can achieve low delay, low jitter and low end-to-end delay, the acoustic network uses different network operator resources to test in each state, and obtains the optimal access network operator resources used to cover different states. Through the mode of the best coverage point and the best network operator combination, a number of local coverage nodes are established to enhance the user experience in India.

4. Facilitate the investigation of problems

In addition, in order to facilitate the development and investigation of customers' business requirements, 1v1 scene API also provides a complete callback API for listening events. At the same time, 1v1 scene API is fully open source, allowing developers to customize and modify internal logic.

Whether it is pure 1v1 social networking or show-to-1v1, Sound Network has launched two sets of scene-based API for these two scenarios, which can achieve best practices. We will also focus on the best practices of the sound network in the show to 1v1 scenarios in another article.
