In the present embodiment, an execution subject of the method provided by the present application is an idle media server, and in the present embodiment, the method provided by the present application includes:
s410: and determining a media server to be taken over.
As described above, in the communication system, each media server may detect itself or other media servers according to a set time period to determine whether there is an abnormality in the media server, and when it is determined that there is an abnormality in the media server, notify the media server whose service processing resource meets a preset condition or determine the abnormal media server as a media server to be replaced by itself. In an embodiment, the idle media server may directly detect that there is an abnormality in the media server, and determine that the media server with the abnormality is the media server to be taken over. In another embodiment, the second other media server may also detect that there is an abnormality in the media server, and notify the idle media server that the service processing resource meets the preset condition. The idle media server is a media server with current service processing resources meeting set conditions, and the set conditions comprise that the available service processing resources are greater than or equal to a preset value and the proportion of the available service processing resources to all the service processing resources is greater than or equal to a preset proportion. In other embodiments, when the number of the media servers whose service processing resources meet the preset condition is multiple, the transmission distance of the idle media servers is also considered when determining the idle media servers, for example, one media server closest to the transmission distance of the abnormal media server is selected as the idle media server from among all the media servers whose service processing resources meet the preset condition.
In another embodiment, when a certain media server in the communication system needs to perform data service transfer due to its own need or due to manual setting by an administrator, a notification may be sent by the media server to the outside to inform each media server in the system that itself needs to perform data service transfer, so that the media server whose service processing resource meets the preset condition in the communication system determines the media server as a media server to be replaced.
The media server to be taken over is a media server which needs to transfer services or is abnormal, and the idle media server is a media server which finally executes the services of taking over the abnormal media server. As described above, the idle media server is a media server whose service processing resources meet the set conditions.
In another embodiment, the idle media server is a media server that detects an abnormal media server and has its own service resources meeting a preset condition. In the present embodiment, the media server whose service processing resource meets the preset condition may be one of all normally operating media servers in the communication system that has the smallest operating pressure, the media server whose service processing resource meets the preset condition may also be one of the media servers that can utilize the most communication resources, or the media server whose service processing resource meets the preset condition may also be a completely idle standby media server that does not have any service in operation, it is understood that the preset condition may be set or changed according to actual needs, and is not limited herein.
In step S410, the idle media server may directly determine the media server to be taken over, or receive a service taking over notification sent by another media server in the communication system. The service taking-over notice is that other media servers which detect abnormal media servers or have service transfer to be carried out are sent to the media server of which the service resources accord with the preset conditions, so that the media server of which the service resources accord with the preset conditions determines the media server to be taken over, and then the service of the media server to be taken over is taken over.
S420: and taking over the service of the media server to be taken over.
And after the idle media server determines the media server to be taken over, further taking over the service of the media server to be taken over. Wherein, the service of the media server to be taken over at least comprises: the method comprises the steps that service data stored on a media server to be taken over and other types of services established by the media server to be taken over are at least obtained and stored.
Further, when the idle media server takes over the service of the media server to be taken over, the identification information of the communication terminal related to the service of the media server to be taken over is acquired, so as to inform the communication terminal with the service to the media server to be taken over to change the data interaction direction.
S430: and sending a redirection request to the terminal related to the service through the RTCP protocol so that the terminal takes the idle media server as a new target media server of the service.
After taking over the service of the media server to be taken over, sending a redirection request to the communication terminal related to the taken over service through the RTCP protocol, so that the communication terminal related to the taken over service takes the idle media server as a new target media server of the ongoing service.
Specifically, according to the acquired identification information of the communication terminal which is related to the service of the media server to be replaced, a redirection request is sent to the communication terminal related to the service through an RTCP protocol so as to inform the communication terminal of changing the data interaction direction, and then the idle media server is used as a new target media server of the service.
The redirection request comprises an effective load type, the value of the effective load type is a preset identifier, and the redirection request is used for informing the terminal to send the data stream of the service to a new target media server. Specifically, the redirection request with the payload type value as the preset identifier is used for notifying the terminal to send the data stream of the service to the new target media server.
Further, in another embodiment, the redirection request further includes address information of the target media server, for informing the terminal of the communication address of the target media server.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a partial structure of a redirection request in an embodiment of a streaming media redirection method according to the present application. In the partial structure diagram of the redirect request illustrated in fig. 5, V is an abbreviation of version number for indicating a version number of the current request, i.e., for identifying a version of the RTCP protocol, P is called Padding, FMT is an abbreviation of feedback message type for indicating a feedback information type of the current redirect request, and PT is an abbreviation of payload type for indicating a current payload type. For example, in the current embodiment, when the payload type is PT (239) illustrated in fig. 5, the different payload types correspond to different signaling, and the different signaling is used to indicate that the current redirection request is used to notify the communication terminal that is sending the service with the media server to be taken over to send the data stream of the service to the new target media server.
Further, the address information includes an IP address and a real-time transport protocol port. With continuing reference to fig. 5, as illustrated in fig. 5, the New Media Server RTP IP is used to notify the IP address of the target Media Server that needs to be connected to the communication terminal that is to take over the transmission of the traffic from the Media Server, and the New Media Server RTP Port is used to notify the communication terminal of the real-time transport protocol Port, so that the communication terminal can transmit the data stream to the target Media Server corresponding to the IP address, and the traffic is reconstructed between the communication terminal and the target Media Server, so that the communication terminal performs data interaction with the target Media Server instead because the Media Server that is to take over performs data interaction.
Still further, the redirect request also includes the type of the target media server. Continuing to refer to fig. 5, the Team Type in fig. 5 is used to indicate the Type of the target media server for the terminal to change other relevant parameters according to actual needs.
According to the technical scheme provided by the application figure 4, after the idle media server determines the media server to be taken over in the communication system, the service of the media server to be taken over is taken over, and the redirection request is sent to the communication terminal related to the service of the media server to be taken over through the RTCP protocol, so that the communication terminal takes the idle media server as a new target media server of the service, the service recovery is quickly completed when the media server is abnormal or needs to perform service transfer, stable data interaction is ensured when the media server is abnormal or performs service transfer, and further, the user experience is improved.
Referring to fig. 6, fig. 6 is a schematic flowchart illustrating another embodiment of a streaming media redirection method according to the present application. In the current embodiment, the step S110 of the idle media server determining the media server to be taken over includes step S601 and step S602. The method comprises the following steps:
s601: the idle media server detects whether a first other media server connected with the idle media server needs to transfer services or is abnormal.
In the current embodiment, the idle media server detects whether the first other media server connected to the idle media server needs to transfer the service or has an abnormality. Wherein the first other media server is a media server connected to the media server performing the detection. The media server in the communication system detects whether the first other media server connected with the media server needs to transfer the service according to a set period. It should be noted that, when a certain media server detects that a first other media server connected to the certain media server is abnormal, it is detected that the first other media server connected to the certain media server needs to transfer a service, and then step S602 is executed, otherwise, step S601 is continuously executed.
Further, in the technical solution provided by the present application, the media server may further detect whether the media server itself is abnormal according to a set period, and when the media server detects that the media server itself is abnormal and the media server itself can still communicate with the outside, send a service taking-over notification requesting to take over the media server to the outside, so that the idle media server determines that the idle media server itself is the media server to be taken over.
Similarly, when it is detected that the administrator issues a setting instruction to the first other media server connected to the administrator to terminate the first other media server from providing the communication service to the external communication terminal, it is determined that the media server or the first other media server needs to transfer the service, and then step S602 is executed, otherwise, step S601 is continuously executed.
Further, in the technical solution provided by the present application, the media server may further detect whether there is a setting instruction sent to the media server by an administrator according to a set period, and when the media server detects that the administrator sends the setting instruction to the media server itself to terminate the media server providing a communication service to an external communication terminal, it is determined that the media server needs to transfer a service, and at this time, the media server may send a service-taking-over notification requesting to take over itself to the outside, so that the idle media server determines itself as the media server to be taken over.
S602: and taking the first other media server as a to-be-taken-over media server, and taking the first other media server as an idle media server when the self service processing resource is determined to meet the preset condition.
If the current detected media server detects that a first other media server needing service transfer or having abnormity exists, the current media server takes the first other media server as a to-be-replaced media server, and when the current media server determines that the service processing resource of the current media server meets the preset condition, the current media server takes the current media server as an idle media server to replace the service of the to-be-replaced media server, and then sends a redirection request to a service-related terminal through an RTCP protocol, so that the idle media server is taken as a new target media server of the service by the terminal.
In another embodiment, when the current media server determines that its own service resources do not satisfy the preset conditions, and when it is detected that there is a first other media server that needs to transfer a service or has an abnormality, the current media server sends a service taking-over notification to the outside, so that the media servers whose own service resources meet the preset conditions in the communication system are used as idle media servers, and then take over the service of the media server to be taken over.
Further, in another embodiment, before the idle media server determines to take over the media server in step S110, the method may further include: and receiving a service succession notification.
The service taking-over notice is generated when the second other media server detects that the service needing to be transferred or the abnormal media server to be taken over exists, and is sent to the idle media server of which the other service processing resources in the communication system meet the preset conditions by the second other media server. It should be noted that, in the current embodiment, the second media server that detects that there is a to-be-replaced media server that needs to transfer a service or is abnormal and the idle media server that finally replaces the to-be-replaced media server are not the same media server.
The media server whose service processing resource meets the preset condition may be the media server with the minimum operating pressure among all the media servers that normally operate in the communication system, the media server whose service processing resource meets the preset condition may also be the media server that can utilize the most communication resources, or the media server whose service processing resource meets the preset condition may also be a completely idle standby media server that does not have any service in operation, it is understood that the preset condition of the service processing resource may be set or changed according to actual needs, and the specific details are not limited herein.
S603: and taking over the service of the media server to be taken over.
S604: and sending a redirection request to the terminal related to the service through the RTCP protocol so that the terminal takes the idle media server as a new target media server of the service.
In the current embodiment, steps S603 and S604 are the same as steps S420 and S430 illustrated in fig. 4, and refer to the description of the relevant parts above, which is not detailed here.
Referring to fig. 7, fig. 7 is a flowchart illustrating a method for redirecting streaming media according to an embodiment of the present application. In the present embodiment, an execution subject of the method provided by the present application is a communication terminal, and the method includes:
s710: a redirect request is received.
Wherein the redirection request is sent to the terminal via the RTCP protocol.
Further, in an embodiment, step S710 includes: the terminal receives a redirection request sent by an idle media server through an RTCP protocol.
When the terminal related to the service of the media server to be taken over receives the redirection request sent by the idle media server through the RTCP protocol, whether the redirection of the streaming media service is needed or not is further judged based on the effective load type, namely the PT value, in the redirection request.
The redirection request comprises an effective load type, and the value of the effective load type comprises a preset identifier to indicate that the redirection request is used for notifying that the data stream of the corresponding service is sent to the new target media server. The data structure of the redirection request may be as described in fig. 5 and its corresponding embodiments, and is not described in detail here.
When the value of the payload type is the preset identifier, it indicates that the current redirection request is used for notifying the terminal to send the data stream of the corresponding service to the new target media server. As an embodiment, the preset flag includes 239. When the PT value in the received redirection request is 239, the communication terminal treats the idle media server as a new target media server for the corresponding service in response to the redirection request.
