[0062] All the above-mentioned optional technical solutions can be combined in any way to form an optional embodiment of the present invention, which will not be repeated here.

[0063] Combine figure 1 The illustrated schematic diagram of the implementation scenario and the content of the above-described embodiment, image 3 It is a flowchart of another message reminding method provided by an embodiment of the present invention. The method is applied to the above figure 1 In the system composed of terminals and servers in image 3 , The method includes:

[0064] 301. The terminal sends a broadcast start notification request to the server, and the broadcast start notification request carries an anchor identifier.

[0065] Wherein, the host identifier can be either the host's ID (Identity), the host's nickname, or the identification information that can identify the host, which is not limited in the embodiment of the present invention.

[0066] Specifically, when the user wants to participate on time when the host starts broadcasting, he can send a broadcasting notification request to the server through the terminal. When receiving the broadcasting notification request, the server extracts the host identification carried in the broadcasting request, and according to the host Identifies the anchor that the user pays attention to. When the server detects that the host that the user is paying attention to starts, it sends a start-up reminder message to the terminal, so that the user knows in time that the host is about to start, and can participate in it on time.

[0067] It should be noted that the broadcast notification request in this step can be in multiple forms. The different forms are described below:

[0068] In the first form, the broadcast notification request is a broadcast notification request for the end user who has followed the anchor.

[0069] The broadcast start notification request carries the identifier of the anchor and the terminal user that the user has paid attention to. When the server detects that the anchor starts, the terminal will be reminded to start the broadcast so that the terminal will not miss the live broadcast.

[0070] In the second form, the broadcast notification request is a follow-up request for any anchor.

[0071] The broadcast start notification request carries any anchor identification and terminal user identification. When the server detects that any anchor starts, the server will remind the terminal to start broadcast so that the terminal will not miss the live broadcast.

[0072] In the third form, the broadcast notification request is a broadcast notification request for the end user not paying attention to the anchor.

[0073] The broadcast start notification request carries the anchor identifier and the terminal user identifier that the user does not follow. For some anchors, the terminal user may only want to watch a certain broadcast, but does not want to pay attention to it. The terminal can send a broadcast notification request for the anchor to the server. When the server detects that the anchor has started, the terminal will Start broadcast reminder so that the terminal will not miss the live broadcast of interest.

[0074] 302. When the server receives the broadcast start notification request, according to the host identifier and user identifier carried in the received broadcast notification request, the user identifier is stored in the broadcast start notification queue of the host.

[0075] Among them, the user identification can be the user's login name, or the user's nickname, and so on.

[0076] The steps 301 to 302 can be the steps performed by the user when he wants to obtain the start-up reminder message of a certain anchor. After the user executes this step, the server can be based on the host ID and the host identifier carried in the received start-up notification request. User identification, storing the user identification in the broadcast start notification queue of the anchor, so that when the broadcast start notification is detected, the broadcast start reminding message is sent to each user in the broadcast notification queue. The steps 301 to 302 can be regarded as a subscription step. Therefore, it only needs to be set before obtaining the start-up reminder message subsequently, and does not need to be repeated in each reminding process.

[0077] 303. The terminal sends an audio reminder file request to the server, and the audio reminder file request carries the host identifier.

[0078] When the terminal accesses the server, the server can display a download button on the host page displayed by the terminal. The download button is used to provide audio reminder file download. When the terminal detects the user's click operation on any download button, it sends the download button to the server. The audio reminder file request corresponding to the download button.

[0079] Among them, the audio reminder file can be a voice file recorded by the host, such as "Hello everyone, it will start broadcasting soon, please participate in time". The host can upload the recorded voice file to the server in advance. When the server receives the voice file, it saves the voice file as an audio reminder file, and establishes the correspondence between the audio reminder file and the host identifier.

[0080] Specifically, when the user wants to start the broadcast on the host, the start-up reminder message used to remind the user is to play the voice file recorded by the host. The user can send an audio reminder file request to the server through the terminal to make the server return the audio reminder file.

[0081] 304. When the server receives the audio reminder file request, it returns the audio reminder file to the terminal.

[0082] When the server receives the audio reminder file request sent by the terminal, according to the anchor ID carried in the audio reminder file request, it searches the audio reminder file library stored on the local end for the audio reminder file corresponding to the anchor ID. When the corresponding audio reminder file is identified, the audio reminder file is returned to the terminal.

[0083] The server can return the audio reminder file to the terminal in different forms. For example, the server can return the audio reminder file itself to the terminal, or it can return the link address corresponding to the audio reminder file to the terminal.

[0084] 305. When the terminal receives the audio reminder file returned by the server, it stores the audio reminder file.

[0085] Corresponding to the form used by the server to return the audio reminder file to the terminal in step 304, when the terminal receives the audio reminder file itself returned by the server, it can directly store the audio reminder file, and when the terminal receives the audio reminder file returned by the server When the link address is corresponding, the terminal can download the audio reminder file according to the link address by itself, and store the audio reminder file when the download is completed.

[0086] The audio reminder file mentioned in the above steps 304-305 is the audio reminder file recorded by the host. In another embodiment provided by the present invention, the audio reminder file may also be recorded by the terminal user and stored on the terminal, that is, Yes, the above steps 304-305 can also be replaced by the following steps, that is, the terminal receives the audio reminder file set by the user for the host identifier, and establishes the correspondence between the audio reminder file and the host identifier.

[0087] In this way, the user can set the audio reminder file corresponding to the host logo on the terminal according to his own situation. For example, the user can set a song that he likes to be an audio reminder file, or the user can record by himself The recording is set as an audio reminder file. For example, the user will record an audio reminder file of "A certain anchor is about to start". It should be noted that the embodiment of the present invention does not limit the specific content of the audio reminder file.

[0088] In order to ensure that the audio reminder file set by the user as the host identifier can be played when the start-up reminder message sent by the server is received, the embodiment of the present invention will also create the audio reminder file set by the user as the host identifier. The corresponding relationship between the reminder file and the anchor ID. By establishing the corresponding relationship between the audio reminder file and the anchor ID, it is possible to query the corresponding audio according to the anchor ID carried in the opening message when receiving the start-up reminder message sent by the server Remind the file, and then play it.

[0089] The above steps 303-305 can be the steps performed by the terminal when acquiring the audio reminder file. After the terminal executes this step, the terminal can store the audio reminder file corresponding to the anchor ID. When the terminal receives the start reminder When sending a message, search for the corresponding audio reminder file according to the host identifier in the start reminder message, and then play it. The steps 303-305 can be regarded as a step of downloading the audio reminder file. Therefore, this step only needs to be executed when the audio reminder file is obtained, and does not need to be executed repeatedly during each reminding process. Of course, if there is an updated audio reminder file on the server side, the terminal user can also be notified to update it.

[0090] 306. When the server detects that the host starts broadcasting, it sends a broadcasting start reminding message to the terminal, and the broadcasting start reminding message carries the host identifier.

[0091] Specifically, when the server detects the start of one of the anchors, it may first obtain the start notification queue of the host, and then send a start reminding message to each user in the start notification queue of the host.

[0092] In the embodiment of the present invention, only the currently detected host’s start notification queue includes the terminal user identifier as an example for description.

[0093] 307. When the terminal receives the start-up reminder message sent by the server, it judges whether the terminal stores an audio reminder file corresponding to the anchor ID according to the anchor ID carried in the start-up reminder message. If yes, go to step 308; if not, go to normal Message reminding process.

[0094] When the terminal receives the start-up reminder message sent by the server, it can extract the host identifier carried in the start-up reminder message, and determine whether the received start-up reminder message needs to play a specific audio reminder file according to the host identifier.

[0095] Specifically, the terminal searches for the audio reminder file corresponding to it in the locally stored audio reminder file library according to the host identifier, and when it finds the corresponding audio reminder file stored locally, it executes step 308. When the corresponding audio reminder file is stored locally, it enters the normal message reminder process, for example, only the message reminder window sent by the server is displayed on the terminal, or only a message reminder is displayed but not displayed on the current interface of the terminal The window, or only the breathing light of the terminal keeps flashing, etc. to provide a reminder, which is not limited in the embodiment of the present invention.

[0096] 308. When the terminal stores an audio reminder file corresponding to the anchor identifier, play the audio reminder file.

[0097] When the terminal stores an audio reminder file corresponding to the anchor identifier, the terminal is triggered to play the audio reminder file. By playing the audio reminder file, the user's attention can be drawn, thereby improving the reminder effect.

[0098] In order to enable the terminal to adapt to the surrounding environment when playing the audio reminder file, the terminal can first detect the surrounding environment before playing the audio and visual reminder file. When the surrounding environment is relatively quiet, the terminal can use a value smaller than the first preset Threshold volume, play the audio reminder file, so that the reminding process does not cause excessive disturbance to the surrounding users. When the surrounding environment is noisy, in order to further improve the reminder effect so that the user can hear the reminder, the terminal can be used in the second preset The threshold volume to play the audio reminder file. Wherein, the second preset threshold is greater than the first preset threshold.

[0099] In order to enhance the reminder effect, the terminal in this embodiment of the present invention may also determine whether the user's viewing operation of the start reminder message is detected within the first preset time range when the audio reminder file is played. When the user's viewing operation of the start-up reminder message is not detected within the time period, the terminal can use a volume greater than the current volume to play, and/or vibrate while playing the audio reminder file, thereby attracting the user's attention.

[0100] In order to prevent users from missing the live broadcast of the anchor, the terminal can also judge whether the user has entered the live broadcast room of the anchor when the audio reminder file ends. When the terminal judges that the user has not entered the live broadcast room of the anchor, the terminal can play the audio reminder file in a loop To remind users. When the terminal detects that the user has entered the live broadcast room of the host or detects that the number of times of looping the audio reminder file reaches the preset number of times, it stops playing.

[0101] Optionally, while the terminal is playing the audio reminder file, it can also display a start-up reminder pop-up window, which includes the host identifier and the start-up information.

[0102] Wherein, the start-up reminder pop-up window may be displayed based on the floating layer above the current display interface of the terminal. The broadcasting information may include information such as the broadcasting time, the broadcasting duration, or a brief introduction to the broadcasting content. By displaying the start reminder pop-up window when the audio reminder file is played on the terminal, the user can not only hear the audio reminder file played by the terminal, but also allows the user to intuitively see the anchor ID and start-up information in the start reminder popup.

[0103] In order to determine that the user can learn about the host’s launching information and improve the reminder effect, the terminal in this embodiment of the present invention can also detect whether the user has performed a viewing operation on the launching reminder pop-up window. When the terminal does not detect the user’s activation of the launching reminder pop-up window When viewing the operation, the display state of the opening reminder pop-up window is always maintained until the user's viewing operation of the opening reminder pop-up window is detected, and the opening reminder pop-up window is closed.

[0104] The message reminding method provided by the embodiment of the present invention sends a broadcast notification request and an audio reminder file request to the server through a terminal, and receives the audio reminder file returned by the server according to the anchor identifier. When the broadcast reminder message is received, the broadcast reminder message is To determine whether the audio reminder file corresponding to the anchor identifier is stored on the local end, and when the audio reminder file corresponding to the anchor identifier is stored on the local end, the audio reminder file is played. In the embodiment of the present invention, the terminal sends the When it is determined that the start-up reminder message is used to remind one of the anchors that he pays attention to, playing the audio reminder file can attract the user’s attention, thereby improving the effect of the message reminder. Furthermore, a variety of different reminding methods can be combined into the play reminding method, which further improves the effect of the message reminder and ensures that the terminal user will not miss the live broadcast that he wants to watch.
