Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The system mainly comprises: a main control unit and a media processing unit; the main control unit is used for sending the media command and the media data to the media processing unit; the media processing unit, i.e. the media processing device, typically employs a digital signal processor (DSP, digital Signal Processor) for executing media commands and processing media data.
Fig. 1 illustrates a process diagram of the operation of a media channel between a master control unit and a media processing unit. As shown in fig. 1, the host in fig. 1 is a main control unit, the DSP chip is a media processing unit, and the host controls the DSP chip to operate the media channels, create operation sub-channels of the media resources, activate the channels, deactivate the channels, and destroy the channels.
The main control unit comprises a channel data control module for managing the media channel, wherein the main parameters of the channel data control module for managing the media channel are channel numbers, used time slot numbers, media channel numbers and channel states.
The media channel operation procedure in fig. 1 is specifically described below:
1. creation of a channel:
the host sends a request for executing the creation channel to the DSP chip, the request for executing the creation channel carries the time slot number used by the channel, and the DSP chip returns the media channel ID to the host for making the association record after the creation is successful. The practical application thereof is as follows:
the TDM bus of the DSP chip is connected to the backplane bus of the device, the so-called TDM bus is a time division multiplexed interface, the 2M interface is 32 time slots, the interface with the time slot number of 0-31,8M is 128 time slots, the time slot number is 0-127. So the time slot IDs seen by the host and the DSP chip are identical, and the media channel number thereof is dynamically applied at the DSP chip end, that is, a procedure in which when the channel 1 of the host creates a channel, the time slot 0 is issued to the DSP chip as a parameter of the creation command, the DSP chip applies for a media channel number associated with the time slot, and returns the media channel number to the channel 1 of the host in the creation channel command return result, and the channel 1 sets the media channel of the channel control module in the host to a return value for subsequently sending the parameter command of the relevant channel to the DSP chip through the recorded media channel ID.
The media channel ID is used to uniquely identify the media channel to be used, and the corresponding channel control data block can be indexed according to the media channel number, and the time slot number (time slot ID) is the number of one physical interface. For example, when the channel 0 uses 0 time slot to transmit data, the 0 time slot is issued to the DSP chip to create a media channel, the DSP chip returns the media channel number to the channel 1 to record, and then the parameters of the host operating channel 1 are issued to the media channel of the DSP chip.
2. Activation of the channel:
the channel is used as the active channel, and the host computer issues the IP information, encoding and decoding, echo, silence detection and other control parameters to control the DSP chip to encode and decode and constitute RTP package for transmission and reception. The echo cancellation is a function of the DSP chip, solves the problem of echo of voice, and the silence detection is to detect whether the voice coming from the TDM interface is silence or not, and if so, the silence packet can be sent to save bandwidth.
3. Deactivation of the channel:
i.e. deactivation, is to deactivate the channel, in which state the channel can be destroyed, freeing the relation between time slots and media channels. That is, the host controls the media channel of the DSP chip to stop receiving and transmitting RTP packets and stop encoding and decoding.
4. Destroying the channel, the host controls the DSP to destroy the media channel, and the host also releases the association relation between the channel number and the media channel.
In fig. 1, once the feedback result from the DSP chip is an unsuccessful result, the media channel is considered to be abnormal, and the state is in an abnormal state.
Thus, from an operational perspective, in an operation triggered from the start of creation to the end of a media channel, empirically, the opportunity for an abnormal media channel to occur is two places, as follows:
1. the generation occurs between the start of creation of the media channel and the start of activation of the media channel, at which time the monitored abnormal media channel is not associated with a media channel number.
2. The generation is after the start of activation of the media channel, when the monitored abnormal media channel is already associated to the media channel number.
And corresponding to the two places where the abnormal media channels are generated, the abnormal media channels can be recovered only by adopting corresponding recovery response schemes respectively, so that the abnormal media channels can be normally used.
Of course, in order not to influence the normal use of the user, the invention also considers the mode of cleaning the abnormal media channel at regular time to improve the utilization rate of the media channel.
Based on the foregoing, as shown in fig. 2, fig. 2 illustrates a flowchart of a media channel fast recovery method provided by the present invention. The media channel quick recovery method comprises the following steps:
s10, presetting a plurality of recovery media channel response schemes under different preset conditions, and establishing a one-to-one mapping relation between each recovery media channel response scheme and each preset condition.
In order to save media resources, the use of the abnormal media channel is restored, and corresponding condition restoration operations are respectively carried out for the condition of the abnormal media channel. In the invention, the abnormal media channel is recovered from three aspects under the condition of not affecting the use of users: firstly, when problems are found in the media operation process, the problems are recovered in time according to the types of the problems, secondly, a period timer is started for 1 hour, the number of media channels in an abnormal state is detected every 1 hour, the channels are recovered according to the corresponding mode of the number of the abnormal media channels, and thirdly, the reset recovery of the DSP is decided according to the current resource use condition and whether a plurality of media boards exist or not at 3 early morning.
It should be noted that the above time points are not limited, and may be set according to the user requirement and the actual scenario.
Based on the three aspects, a plurality of recovery media channel response schemes under different preset conditions are preset in the system, and a one-to-one mapping relation between each recovery media channel response scheme and each preset condition is established. The method comprises the following steps:
the first preset condition is that the number of the media channels in the abnormal state exceeds ten percent of the total number of the media channels, and the corresponding first recovery media channel response scheme is that when no other user terminal uses any media channel is detected, all the media channels are initialized.
Under the condition based on the first preset condition, a fourth preset condition is preset to determine that a plurality of standby media control boards are stored, the corresponding fourth recovery media channel response scheme is to inform the main control board to perform main-standby switching operation, transfer the used media resources to the standby media control boards, determine that the DSP chip is not used, and perform reset operation on the DSP chip.
The second preset condition is that the result of unsuccessful feedback creation operation is fed back, and the corresponding second recovery media channel response scheme is that the media channel corresponding to the creation operation is initialized. The second recovery media channel response scheme is based on point 1 above.
The third preset condition is that the feedback activation operation is unsuccessful, and the corresponding third recovery media channel response scheme is to perform deactivation operation processing and destruction operation processing on the media channel corresponding to the activation operation until the media channel can be normally used. The third recovery media channel response scheme is based on point 2 above.
S20, the system monitors operation response results of all operations triggered from the start of creation to the end of the media channel and the number of the media channel in an abnormal state.
Because the system is easy to cause excessive abnormal media channels during long-time operation, the abnormal media channels cannot be used, and the space is extremely occupied, the system is set to detect the states of the media channels at intervals of preset time so as to acquire the number of the media channels in the abnormal state. Whether the number reaches a certain range is determined to determine whether initializing operation is required for all media channels, namely resetting the DSP chip.
Of course, since the generation of the abnormal media channel also originates from the operation process from the creation of the media channel to the end, the system needs to monitor the operation response results of all the operations triggered from the creation of the media channel to the end, so as to judge whether the media channel is abnormal according to the operation response results, and then timely take the corresponding recovery operation.
S30, if the operation response result or the number meets any preset condition, acquiring a recovery media channel response scheme corresponding to the preset condition according to the mapping relation between the preset recovery media channel response scheme and the preset condition.
Based on step S10, different recovery media channel response schemes under different preset conditions are stored in advance, and under the condition of system monitoring, whether the number of abnormal media channels monitored in the operation process from the start of media channel creation to the end of triggering or in other time periods is not the same, if any preset condition in the prestored condition is met, the recovery media channel response scheme corresponding to the preset condition is obtained, and the corresponding recovery media channel response scheme can be executed for the abnormal media channels.
I.e., the number of media channels in an abnormal state exceeds ten percent of the total number of media channels (satisfying a first preset condition), a first recovered media channel response scheme is obtained.
If the system monitors that the operation triggered by the media channel is the creation operation of the media channel and the operation response result is that the feedback creation operation is unsuccessful (namely, the second preset condition is met), a second recovery media channel response scheme is obtained.
If the system monitors that the operation triggered by the media channel is the activation operation of the media channel and the operation response result is that the feedback activation operation is unsuccessful (namely, the third preset condition is met), a third recovery media channel response scheme is obtained.
And if the state of the monitoring media channel is in an abnormal state (namely, the fourth preset condition is met) at intervals of preset time, acquiring a fourth recovery media channel response scheme.
S40, executing recovery operation on the media channel through the recovery media channel response scheme, so that the media channel can be normally used.
In specific implementation, a timer is started, and the timer is set to be a preset time, for example, the preset time is 1 hour; if the current duration reaches the preset time, the timer sends a state detection instruction of the media channel to the system; after the system receives the state detection instruction, acquiring the states of all media channels, and if the states of the media channels are monitored to be in abnormal states, counting the number of the media channels in the abnormal states; judging whether the number meets a first preset condition, if so, executing a first media channel restoration response scheme corresponding to the first preset condition, namely determining that no other users are used on the DSP chip, resetting the DSP chip and initializing all channels.
Of course, when the first recovery media channel response scheme is executed, if it is detected that there are a plurality of unused standby media control boards (meeting a fourth preset condition), the fourth recovery media channel response scheme is executed, specifically, before the reset operation is performed on the DSP chip, the main control board on the host computer is notified to perform the migration operation, and all the media resources used by the subsequent user are migrated to the standby media control boards until no other user is present on the DSP chip, and the DSP is reset. Therefore, normal use of the user is not influenced, abnormal media channels can be used normally, space is saved, and the utilization rate of the media channels is greatly improved.
Further, the occurrence of abnormal media channels is monitored during the course of the media channels from the beginning to the end of creation, i.e
If the operation response result meets the second preset condition, the channel state before entering the abnormal state is created to wait and is not related to the media channel number, and the control data block of the channel can be used after being directly initialized.
If the operation response result meets the third preset condition, the channel is found to have an associated media channel number, which indicates that the media channel also exists, and the deactivation operation is issued to the channel to cause all operations of deactivation to the idle state, that is, all operations from the deactivation operation in fig. 1 to the media channel in the idle state are executed.
Therefore, based on the steps S10-S40, the method and the device for recovering the media channels in the abnormal state are based on the condition that the user is not affected badly, and the recovery operation is carried out through various recovery mechanisms, so that the media channels are converted into the normal usable state, the usable media channels are increased, the utilization rate of media resources is improved, the resources are saved, the cost is reduced, the abnormal scene is covered comprehensively, and great convenience is brought to the user by utilizing popularization.
