This optional embodiment provides the prerequisite information of connection establishment for the realization of the live connection of the intelligent terminal 11 in the live service system, which is equivalent to the trigger condition of the live connection establishment, and ensures the effective implementation of the live connection establishment of the intelligent terminal 11.
Meanwhile, as a parallel optional embodiment of the above optional embodiments of this embodiment, the live broadcast system may further include a resource allocation server and an anchor terminal (neither shown in fig. 1), specifically, the anchor terminal is configured to send a resource allocation request of an anchor to be served to the resource allocation server; the resource allocation server is configured to select onemedia server 121 from the media server group 12 as aselected media server 121 of the anchor to be served after receiving the resource allocation request. Accordingly, the selectedmedia server 121 is used to synchronize media information formed based on the anchor information of the anchor to be served into a guidingprocess 122 belonging to the same media server farm 12.
In this optional embodiment, the live broadcast service system further includes a anchor terminal on which an anchor client facing an anchor user is installed, and the live broadcast service system further includes a resource allocation server for performing server allocation to the anchor terminal.
For example, in this optional embodiment, an anchor with an online live broadcast requirement may be used as a to-be-serviced anchor, and an anchor terminal held by the to-be-serviced anchor may send a resource allocation request corresponding to the to-be-serviced anchor to a resource allocation server. A resource allocation policy for resource allocation is set on the resource allocation server, and themedia server 121 may be allocated to the anchor to be served according to the resource allocation policy and the information carried in the resource allocation request.

Example two
Fig. 2 is a schematic structural diagram of a live broadcast service system according to a second embodiment of the present invention, where the first embodiment of the present invention is optimized based on the foregoing, as shown in fig. 2, the present embodiment includes anintelligent terminal 20 and a media server group 23, and the live broadcast service system further includes: a signaling channel 21 and a media front-end server 22; theintelligent terminal 20 is connected to the media front-end server 22 through the signaling channel 21, and the media front-end server 22 is connected to the media server group 23. Specifically, the media front-end server 22 is configured to, when receiving a first guiding process address obtaining request sent by theintelligent terminal 20, feed back a guiding process address of aguiding process 232 in the media server group 23 to theintelligent terminal 20 through the signaling channel 21.
In this embodiment, the key for establishing the connection between theintelligent terminal 20 and the target media server 231 corresponding to the anchor to be connected is accessing theguiding process 232, and the access from theintelligent terminal 20 to theguiding process 232 specifically depends on the guiding process address, and the guiding process address possessed when the intelligent terminal sends the access request to theguiding process 232 in this embodiment may be obtained by the media front-end server 22 in advance. The media front-end server 22 may specifically be understood as a server on which theintelligent terminal 20 depends on information interaction with a server of the live broadcast application before establishing connection with the media server 231, and the signaling channel 21 and the media front-end server 22 may be integrally regarded as a signaling background to connect theintelligent terminal 20 and the media server cluster 23.
Specifically, for theintelligent terminal 20, after the intelligent terminal 20 starts the installed live broadcast client based on the click trigger of the viewer user, a guiding process address acquisition request may be first sent to the media front-end server 22 through the signaling channel 21, and then a guiding process address fed back by the media front-end server 22 may be received, and theintelligent terminal 20 may receive and pre-store the guiding process address, where the guiding process address acquisition request may include the terminal identification information of theintelligent terminal 20.
For the media front-end server 22, it specifically establishes a connection with the media server group 23, may obtain a guidance process address of theguidance process 232 in the media server group 23, and may then send the guidance process address to theintelligent terminal 20 corresponding to the terminal identification information according to the terminal identification information included in the guidance process address acquisition request.
It should be noted that, in this embodiment, the precondition for acquiring the address of the guiding process is that the live broadcast server system includes one media server group 23, which is different from a case where the subsequent live broadcast server system includes at least two media server groups 23, and this embodiment records the address of the guiding process as the first address of the guiding process acquiring request.
The live broadcast service system provided by the embodiment of the invention embodies the implementation mode of the intelligent terminal for acquiring the lead process address, provides basic information support for the establishment of the live broadcast connection between the intelligent terminal and the target media server, and ensures the integrity of the live broadcast connection establishment scheme.
Further, fig. 3 is a schematic diagram of an architecture of another live broadcast service system provided in the second embodiment of the present invention. As shown in fig. 3, the media server farm 34 further includes at least oneaudio media server 341, at least onevideo media server 342, anaudio guide process 343 associated with each of theaudio media servers 341, and avideo guide process 344 associated with each of thevideo media servers 342. Meanwhile, the media front-end server 33 further specifically includes an audio front-end server 331, a video front-end server 332, and an integration process 333, wherein the signalingchannel 32 is connected to the audio front-end server 331 and the video front-end server 332 through the integration process 333, respectively.
As can be seen from fig. 3, the audio front-end server 331 is specifically connected to theaudio guidance process 343 in the media server farm 34, and the video front-end server 332 is specifically connected to thevideo guidance process 344 in the media server farm 34. Based on the connection relationship given in fig. 3, the audio front-end server 331 may obtain the audio guidance process address of theaudio guidance process 343, and the video front-end server 332 may also obtain the video guidance process address of thevideo guidance process 344. When the integration process 333 receives the guidance process address acquisition request sent by theintelligent terminal 31, the integration process 333 may integrate the audio guidance process address and the video guidance process address to form a guidance process address, and the guidance process address is fed back to theintelligent terminal 31 through the signalingchannel 32.
In the second embodiment of the live broadcast service system under the system architecture, the media server group realizes separate service support for multimedia information, specifically deploys an audio media server for audio service support, deploys a video media server for video service support, and simultaneously associates the audio media server with the audio guide process and associates the video media server with the video guide process, thereby integrally ensuring effective implementation of live broadcast connection application in live broadcast application software.
As an optional embodiment of the second embodiment of the present invention, the second embodiment further optimizes that the live broadcast service system includes at least two media server clusters, wherein the media front-end server is respectively connected to each of the media server clusters.
In the live server system given in this optional embodiment, the media front-end server is further configured to determine a target media server group from each media server group according to a second guidance process address acquisition request sent by the intelligent terminal, and feed back a guidance process address of a guidance process in the target media server group to the intelligent terminal through the signaling channel.
It should be noted that, in the live broadcast service system including at least two media server groups, an access request is also generated after the anchor to be connected is determined on the intelligent terminal, and the access request can also be sent to the corresponding guide process according to the pre-obtained guide process address. It can be seen that the key for connecting the intelligent terminal with the target media server corresponding to the anchor to be connected still lies in the acquisition of the address of the guiding process. Specifically, the intelligent terminal is first required to send a second guiding process address acquisition request to the media front-end server, and the media front-end server can find a target media server group corresponding to the second guiding process address acquisition request from the plurality of connected media server groups and feed back a guiding process address of a guiding process in the target media server group to the intelligent terminal. The method is different from the method for acquiring the guide process address sent by the intelligent terminal when the live broadcast service system comprises one media server group, and the guide process address acquired request sent by the intelligent terminal under a plurality of media server groups is recorded as a second guide process address acquired request.
It will be appreciated that in the live service system given in this alternative embodiment, when there are multiple media server clusters in the live service system, each media server cluster may be considered to include at least one media server and a guidance process associated with each media server in the same media server cluster. In this embodiment, it can be considered that a plurality of media server groups form a media background for supporting live broadcast services, each media server group can be respectively regarded as a machine room for performing distributed division in different regions, each machine room is deployed with a plurality of media servers and a guidance process associated with each media server, and each machine room is correspondingly provided with a region deployment information, so that the media server groups in different regions have different region deployment information.
For the media front-end server, the media front-end server may analyze the region information of the terminal of the intelligent terminal included in the received second guiding process address acquisition request, and then may compare the region information of the terminal with the region deployment information of each media server group, thereby selecting a target media server group from the multimedia server groups, where the region deployment information matches the region information of the terminal, and finally may feed back the guiding process address of the guiding process added in the target media server group to the intelligent terminal.
It should be noted that, after the intelligent terminal sends the second guidance process address acquisition request to the media front-end server each time, the intelligent terminal may only receive the guidance process address corresponding to the guidance process included in one media server group selected by the media front-end server from all the media server groups.
Further, the intelligent terminal may be specifically configured to send the second guiding process address acquisition request to the media front-end server at a set update period, where the second guiding process address acquisition request includes information of a region where the terminal is located.
In this embodiment, the timing when the intelligent terminal first sends the second guidance address acquisition request to the media front-end server may be after the installed live broadcast client is started, so as to first acquire a guidance process address required for accessing the guidance process. Further, in order to ensure the accuracy of the guiding process address prestored in the intelligent terminal, in this embodiment, the intelligent terminal periodically updates the guiding process address in the operation process of the live broadcast client, specifically, the intelligent terminal may repeatedly send the second guiding process address acquisition request to the media front-end server at a set update period (e.g., 15 minutes, 30 minutes, or 1 hour, etc.), so that the second guiding process address acquisition request sent by each update may be corresponded to, and the guiding process address correspondingly fed back by the media front-end server is received.
It can be known that the second guidance address obtaining request includes the region information where the terminal of the intelligent terminal is located, the media front-end server may determine a media server group matched with the region of the intelligent terminal from each machine room of the media backend 3 according to the region information where the terminal is located, the matched media server group may be marked as a target media server group, and a guidance process address provided by a guidance process added in the target media server group may be fed back to the intelligent terminal through a signaling channel.
Further, the media front-end server may be specifically configured to acquire region deployment information corresponding to each media server group on the media background, and extract region information where the terminal in the second guiding process address acquisition request is located; taking a media server group corresponding to the region deployment information matched with the region information of the terminal as a target media server group; and feeding back the guiding process address of the guiding process in the target media server group to the intelligent terminal through the signaling channel.
Generally, when the location of the audience user does not change, the region information of the terminal of the intelligent terminal held by the audience user does not change, and at this time, if the guiding process address is received in a set updating period, the currently received guiding process address may be the same as the guiding process address received in the previous updating period; however, when the location of the viewer user and the location of the intelligent terminal held by the viewer user change, the region information of the terminal corresponding to the intelligent terminal also changes, and at this time, in the operation of receiving the address of the guiding process in the set updating period, the currently received address of the guiding process may be different from the address of the guiding process received in the previous updating period, because: the media server group in the live broadcast service system, which is matched with the changed region information of the terminal, may be changed, so that the currently determined guiding process address of the media front-end server should be the guiding process address matched with the changed region information of the terminal.
The second embodiment of the present invention provides a live broadcast service system according to the above-mentioned optional embodiment, which embodies an implementation manner in which an intelligent terminal acquires a guide process address when a plurality of media server groups are included, perfects an implementation process of live broadcast connection establishment for audience users, provides basic information support for execution of connection establishment, and ensures integrity of a connection establishment technical scheme.
As another optional embodiment of the second embodiment, the second embodiment further optimizes the live broadcast service system on the basis of the above embodiment, and specifically, in the live broadcast service system, the intelligent terminal 21 may be further configured to send a request for updating a guide process address to the media front-end server when it is monitored that the connection with the target media server fails; the media front-end server is further used for determining a new target media server group matched with the anchor to be connected from each media server group according to the guiding process address updating request, and feeding back a new guiding process address of a new guiding process in the new target media server group to the intelligent terminal; and the intelligent terminal is used for sending an access request to a new guide process corresponding to the new guide process address so as to determine a new target media server from the new target media server group through the new guide process and establish connection.
It can be understood that, in practical applications, the target media server pre-allocated by the anchor to be connected existing on the intelligent terminal 21 may not be included in the target media server group corresponding to the currently obtained guiding process address of the intelligent terminal 21, that is, after the access request is sent to the guiding process corresponding to the obtained guiding process address, the media server group to which the guiding process belongs may not include the target media server corresponding to the anchor to be connected. At this time, the guidance process receiving the access request cannot find the target media server matched with the anchor to be connected in the home media server group, so that the connection between the intelligent terminal 21 and the target media server cannot be successfully established.
In this embodiment, when the guiding process does not determine the target media server corresponding to the anchor to be connected, the guiding process may send information that the connection establishment with the target media server corresponding to the anchor to be connected fails to the intelligent terminal 21, at this time, the intelligent terminal 21 may generate a guiding process address update request, where the guiding process address update request includes anchor information of the anchor to be connected, the anchor information may specifically include an anchor ID and region information where the anchor is located, and the guiding process address update request may also be received by the media front-end server 222.
Correspondingly, the media front-end server 222 may obtain anchor information in the guiding process address updating request, and then may search the resource allocation cache table to determine a new target media server group where a new target media server matched with the anchor information is located; after determining the new target media server group, the media front-end server 222 may determine a guiding process added in the new target media server group as a new guiding process, and determine a guiding process address of the new guiding process as a new guiding process address to feed back to the intelligent terminal 21, where the resource allocation cache table may be understood as an allocation log, which is a global variable set on the resource allocation server on the media backend 23, after the resource allocation server in the media backend allocates the media server to the anchor, the anchor information of the anchor and the allocated media server may be synchronously recorded in the resource allocation cache table, and when the anchor exits the direct broadcast, the relevant record of the anchor is deleted from the resource allocation cache table.
After receiving the new guiding process address, the intelligent terminal may send an access request to a new guiding process corresponding to the new guiding process address, so as to determine a new target media server from the new target media server group through the new guiding process and establish a connection.
The live broadcast service system provided by the optional embodiment provides the operation of updating the guide process address when the connection establishment with the target media server fails, and ensures that the connection with the target media server is realized through the updated guide process address.
