Detailed Description
The technical scheme in the application is further described in detail below with reference to the accompanying drawings.
The application discloses a signal processing method which is applied to a server for providing network service for a terminal, when the terminal finds that the call quality in the call process is reduced, the terminal sends a request to the server, and at the moment, the server sends a data packet which needs to be sent to the terminal and is associated with the call service to the terminal after optimization adjustment.
After receiving the optimized and adjusted data packet, the terminal carries out targeted processing on the data packet, wherein the optimized and adjusted data packet received by the terminal is divided into two types, one type is a normal data packet, the other type is a blank data packet, the normal data packet is processed according to a normal processing process, and digital signals are converted into electric signals; the blank data packet is processed by using a mode of analog addition prediction, wherein the analog addition prediction supplements the lost data back by means of calculation and waveform change trend, namely, the blank data packet is changed into a usable normal data packet.
Referring to fig. 1, the signal processing method disclosed in the present application is applied to the aforementioned server, and the method includes the following steps:
s101, responding to the acquired request, and determining a channel of a terminal associated with the request in a communication channel;
s102, checking the time interval between adjacent data packets in unit time length in a channel;
s103, when the number of the data packets in the unit time length is smaller than the set number or the time interval between the adjacent data packets exceeding the set number is larger than the set time, marking the data packets in the unit time length as abnormal data packets and adjusting the time interval between the abnormal data packets to be within a normal value range;
s104, inserting one or a plurality of continuous blank data packets in a blank time period in unit time length;
s105, compressing channel resources of the terminal not associated with the request when adjusting the time interval, and transferring the channel resources to a channel of the terminal associated with the request; and
and S106, when the blank data packet does not exist in the unit time length, transferring the channel resources of the terminal associated with the request to the channel of the terminal not associated with the request.
Specifically, in step S101, the terminal sends a request to the server, where the purpose of the request is to request the server to process a packet passing through a channel of the terminal associated with the request, and the precondition that the terminal sends the request is that the received packet sent by the server is lost or that the interval between adjacent packets is long. Then in response to the acquired request the server will first determine the channel of the terminal in the communication channel associated with the request.
In step S102, the server checks the time interval between adjacent data packets in a unit time length of the channel, where the unit time length is a fixed time length, and the checking process is as follows, as shown in fig. 2, in the normal data packet transceiving process, the number of data packets in the unit time length is N, and the time interval between adjacent data packets is t; as shown in fig. 3, when the number of data packets per unit time length is smaller than N, the time interval between adjacent data packets is T, and the relationship between T and T is greater than, equal to, and smaller than three cases.
Step S102 is a data collection process before determination, and specific determination and adjustment processes are performed in step S103. In step S103, when the number of data packets per unit time is smaller than the set number or the time interval between adjacent data packets exceeding the set number is longer than the set time, the data packets per unit time are marked as abnormal data packets and the time interval between the abnormal data packets is adjusted to be within the normal value range.
The number of data packets in unit time length and the time interval between adjacent data packets are two, and if one of the two judging conditions is not met, the data packets in the whole unit time length are marked as abnormal data packets.
It should be understood that the number of data packets per unit time being smaller than the set number may result in a decision condition that the time interval between the adjacent data packets of the set number cannot be triggered to be larger than the set time, for example, the number of data packets per unit time is two, and the time interval between the two data packets meets the requirement, but the decision condition that the time interval between the adjacent data packets of the set number cannot be triggered to be larger than the set time is not triggered.
In step S104, referring to fig. 4, one or more consecutive blank packets are inserted in a blank period of a unit time, where the total number of blank packets and existing packets is equal to the theoretical number of packets of the unit time.
The insertion of the blank data packet can also refer to the sequence number carried by the data packet, wherein the sequence number represents the position of the data packet on the sequence, the insertion mode is as follows, the data packet is lost, and the blank data packet is inserted at the lost position according to the sequence number; the time of receipt of the data packet is delayed, the position of the data packet on the time line is adjusted according to the sequence number, and then one or a plurality of continuous blank data packets are inserted in a blank time period in the time length.
Next, step S105 is performed, in which the channel resources of the terminal not associated with the request are compressed during the adjustment of the time interval, and the channel resources are transferred to the channel of the terminal associated with the request. The function of step S105 is to expand the channel resources of the terminal requesting association to solve the problems occurring in steps S102 to S104.
It should be understood that when the number of data packets per unit time is smaller than the set number or the time interval between adjacent data packets exceeding the set number is longer than the set time, the channel resource may be regarded as a road having a fixed lane due to the insufficient channel resource, and the data packets may be regarded as vehicles moving on the road, and when the number of vehicles increases beyond the road load, a jam phenomenon may occur.
Therefore, the application adopts a mode of transferring other signal resources to expand the channel of the terminal which requests to be associated so that the data throughput of the channel can meet the use requirement of the terminal which requests to be associated.
Meanwhile, as for the channel resources, a processing method of dynamic allocation is also used, specifically, in step S106, when there is no blank packet in a unit time length, the channel resources of the terminal associated with the request are transferred to the channels of the terminals not associated with the request.
Specifically, the unit time length can be divided into two types, that is, a blank packet exists and a blank packet does not exist, and when the blank packet exists in the first unit time length in the sequence, the available channel resources are transferred to the channel of the terminal associated with the request, and when the unit time length in which the blank packet does not exist again in the sequence, the channel resources are transferred to the channel of the terminal not associated with the request.
In summary, the signal processing method provided by the application uses two judging conditions of the number of data packets in unit time and the time interval between adjacent data packets to judge the data packet passing condition of the channel on the terminal associated with the request, and when the number of the data packets in unit time is smaller than the set number or the time interval between the adjacent data packets exceeding the set number is larger than the set time, the received data packets are actively adjusted in time and other channel resources are mobilized to dynamically expand the channel of the terminal associated with the request, so as to relieve the channel congestion condition of the terminal associated with the request.
In addition, for the mobilization of other channel resources, a dynamically adjusted mobilization mode is used, so that the channel dynamic expansion of the terminal related to the request is realized with minimal influence.
In some examples, adjusting the interval between the abnormal data packets to be within a normal range of values includes the steps of:
s201, acquiring the receiving time of the first abnormal data packet and the receiving time of the last abnormal data packet in unit time length and obtaining the processing range time; and
s202, arranging the abnormal data packets in sequence on the processing range time and filling blank segments on the processing range time by using blank data packets.
In step S201 and step S202, referring to fig. 5, for the processing mode of the abnormal data packet, the processing is performed by using a centralized processing mode, that is, the abnormal data packets in a unit time length are sequentially arranged, the time interval between adjacent abnormal data packets is adjusted according to the set time interval, and then the blank data packets are used to fill the blank section in the processing range in time.
The processing mode can concentrate blank sections and is convenient for concentrated filling. When the terminal fills the lost data packet in the blank section by using an analog addition calculation mode, the terminal refers to the data packet in the sequence to fill, and when the terminal cannot fill, the terminal directly performs the blank processing.
In some examples, for the processing range time in step S202, a segmentation process is also required, where the rule of the segmentation process is to segment the processing range time when the processing range time is greater than the set time length, and the length of each segment of the processing range time is less than or equal to the set time length.
The purpose of segmenting the processing range time is to compress the length of the blank segment, because the too long length of the blank segment can cause the situation that the terminal cannot fill when filling and easily occurs.
In some possible implementations, when the processing range time is segmented, the length of the last processing range time in the sequence is smaller than the set time length, and the length of the other processing range time is equal to the set time length.
Referring to fig. 6, in some examples, transferring channel resources to a channel of a terminal associated with a request includes the steps of:
s301, acquiring the utilization rate of channel resources and the amount of cache resources of a terminal which is not associated with the request;
s302, compressing channel resources of a terminal which is not associated with a request according to the utilization rate and the buffer resource amount to obtain abundant channel resources; and
s303, transferring the channel resources to a channel of a terminal associated with the request;
the number of the abundant channel resources is one or more, and the abundant channel resources also comprise a starting time and a cut-off time.
Specifically, in steps S301 to S303, the amount of abundant channel resources is determined according to the usage rate and the amount of buffer resources of the channel resources of the terminal not associated with the request, and the usage rate may be directly used for compressing the channel resources of the terminal not associated with the request; the amount of buffer resources may be indirectly used to compress channel resources of the terminal that are not associated with the request.
It should be appreciated that when the utilization is less than one hundred percent, this indicates that the channel is not fully loaded at this time, and that the excess channel resources may be transferred directly. The buffer resource amount indicates that the channel can be completely transferred within a time corresponding to the buffer resource amount, for example, the channel is used in audio and video playing.
In the process of acquiring the abundant channel resources, channels with the utilization rate less than one hundred percent are preferably selected for compression. If the quantity of the abundant channel resources is insufficient at this time, then the channel with the buffer resource quantity is compressed, in the compression process, the starting time and the deadline corresponding to the buffer resource quantity need to be determined, splicing is performed according to the starting time and the deadline, and then a plurality of channels with the buffer resource quantity are compressed.
In some possible implementations, the start time and the expiration time of the blanking period are within the time length of the rich channel resources after the channel resources are transferred.
In some examples, when the time length corresponding to the blank data packet exceeds the allowed time length, the method further includes:
s401, obtaining the buffer resource quantity of the channel resource of the terminal which is not associated with the request; and
s402, channel resources in the time length corresponding to the blank data packet are transferred to a channel of a terminal which is insufficient in buffer resource quantity and is not associated with the request.
The contents in step S401 and step S402 are that the channel resource utilization ratio temporarily transferred to the terminal associated with the request is optimized, and when the data packet corresponding to the terminal associated with the request is filled with the blank data packet, the channel resource is in an idle state at this time, so that the channel resource over the time length corresponding to the blank data packet is transferred to a channel which has insufficient buffer resource amount and is not associated with the terminal associated with the request in the present application.
By the method, the buffer resource quantity of the corresponding terminal on other channels can be increased, and channel resources which can be transferred can be provided when the channel resources of the terminal associated with the request are insufficient again.
The application also provides a signal processing device, which comprises:
a first processing unit, configured to determine, in response to the acquired request, a channel of a terminal associated with the request in the communication channel;
a monitoring unit for checking a time interval between adjacent data packets per unit time length in the channel;
the second processing unit is used for marking the data packets in the unit time length as abnormal data packets and adjusting the time intervals among the abnormal data packets to be within a normal value range when the number of the data packets in the unit time length is smaller than the set number or the time intervals among the adjacent data packets exceeding the set number are larger than the set time;

and a second inserting unit for arranging the abnormal data packets in sequence on the processing range time and filling the blank section on the processing range time by using the blank data packets.
Further, when the processing range time is longer than the set time length, the processing range time is segmented, and the length of each processing range time is smaller than or equal to the set time length.
Further, when the processing range time is segmented, the length of the last processing range time in the sequence is smaller than the set time length, and the lengths of the other processing range times are equal to the set time length.
Further, the method further comprises the following steps:
