Abstract
This application discloses a kind of methods for shielding uplink packet loss, comprising: data relay center receives the data packet that speaker's equipment is sent；Data relay center judges the sequence number of the data packet received；When sequence number interrupts, modify to the sequence number of the data packet after at interruption, so that the sequence number of modified data packet is continuous；Data relay center delivers a packet to receiving device.Disclosed herein as well is a kind of equipment for shielding uplink packet loss.Using technical solution disclosed in the present application, the complexity of packet loss processing can reduce, and shorten the time delay of audio group call forwarding hair.
Description
Technical field
This application involves field of communication technology, in particular to a kind of method and apparatus for shielding uplink packet loss.
Background technique
With the development of group service, voice group call service using more and more extensive, existing audio group call forwarding hair applies mould
Formula is substantially such as Fig. 1.Referring to Fig. 1:
It is exhaled in forwarding model in audio group, A sends audio data to data relay center, by data relay as speaker
The audio data received from A is forwarded to B, C and D by center.
The audio data that speaker A is sent is to be sent to data relay center by real-time transport protocol (RTP) packet, so
Afterwards, the RTP data received from A will be sent to B, C and D by RTP packet by data relay center.
In actual application, terminal described in Fig. 1 is in wireless network environment, if locating for some terminal
Network environment is bad, will lead to packet loss.In certain application scenarios, it would be desirable to uplink network packet loss is masked, to guarantee
Processing under certain scenes is normally, for example, in scene below:
Network environment where A is bad, and packet loss occurs in the audio RTP packet that A is sent to data relay center, in data relay
After the heart receives the audio RTP packet that terminal A is sent, it is sent to tri- receiving ends B, C and D；Receiving end is receiving audio RTP packet
Afterwards, detect that packet loss, audio player may suspend broadcasting, and buffering audio data, the user at such end B, C and D
The sound heard be exactly it is desultory, effect is bad.
The method of currently used shielding uplink packet loss is to carry out Discarded Packets compensation.When finding that audio RTP packet is discontinuous
It waits, several insert silent audio frames can be compensated in centre, be then sent to receiving end.The method for compensating insert silent audio frame is as shown in Figure 2:
Assuming that packet loss occurs for audio RTP packet, the RTP packet number that receiving end receives is 1,2, and centre is lost 3,4,5 three
A audio pack adds 345 3 insert silent audio frames when compensating insert silent audio frame among RTP packet number 2 and 6, protects in this way
The continuity of audio RTP packet is demonstrate,proved.
But there are some problems for the above method.It is to increase complexity first, needs to generate the algorithm of insert silent audio frame；
Time delay is followed by increased, because to mend quiet frame, it is necessary to buffer a certain amount of audio RTP bag data, just can guarantee and receive
RTP packet it is continuous, and then can just calculate the data of audio pack packet loss, insert silent audio frame can be mended.
Summary of the invention
This application provides a kind of methods and apparatus for shielding uplink packet loss, to reduce the complexity of packet loss processing, and contract
The time delay of short audio group call forwarding hair.
This application discloses a kind of methods for shielding uplink packet loss, comprising:
Data relay center receives the data packet that speaker's equipment is sent；
Data relay center judges the sequence number of the data packet received；
When sequence number interrupts, modify to the sequence number of the data packet after at interruption, so that modified
The sequence number of data packet is continuous；
Data relay center delivers a packet to receiving device.
Preferably, the method is applied to cluster multi call business；
The data packet is audio realtime transmission protocol RTP packet.
Disclosed herein as well is a kind of equipment for shielding uplink packet loss characterized by comprising
For receiving the receiving module of the data packet of speaker's equipment transmission；
The judgment module judged for the sequence number to the data packet received；
For when sequence number interrupts, modify to the sequence number of the data packet after at interruption, so that modification
The continuous modified module of the sequence number of data packet afterwards；
For delivering a packet to the sending module of receiving device.
Preferably, the equipment application is in cluster multi call business；
The data packet is audio realtime transmission protocol RTP packet.
As seen from the above technical solution, the method and apparatus that the application shields uplink packet loss, passes through data relay center pair
The sequence number of the data packet received is judged, when sequence number interrupts, to the sequence of the data packet after at interruption
It number modifies, so that the sequence number of modified data packet is continuous, to reduce the complexity of packet loss processing, and shortens
The time delay of audio group call forwarding hair.Realization mechanism of the present invention is simple, and can achieve the effect that mend insert silent audio frame algorithm.
Detailed description of the invention
Fig. 1 is that model schematic is sent out in audio group call forwarding；
Fig. 2 is the method schematic diagram for compensating insert silent audio frame；
Fig. 3 is the method schematic diagram of present invention shielding uplink packet loss.
Specific embodiment
It is right hereinafter, referring to the drawings and the embodiments, for the objects, technical solutions and advantages of the application are more clearly understood
The application is described in further detail.
To solve the problems of prior art, a kind of method that the application proposes new shielding uplink packet loss, the party
Method judges the sequence number of the data packet received by data relay center, when sequence number interrupts, to interruption
The sequence number of data packet after place is modified, so that the sequence number of modified data packet is continuous.
The schematic diagram that the present invention shields the method for uplink packet loss is as shown in Figure 3:
When receiving the packet that audio RTP packet number is 2,3,4,5 three packets of intercalary delection, data relay center is received
When the packet of Serial No. 678, corresponding sequence number is revised as 3,4,5.This ensures that, be sent to data relay center in A
Audio RTP packet packet loss when, the audio RTP packet number that data relay center is distributed to B, C and D is continuous, this realization machine
System is simple, and can achieve the effect that mend insert silent audio frame algorithm.
Corresponding to the above method, disclosed herein as well is a kind of equipment for shielding uplink packet loss, comprising:
For receiving the receiving module of the data packet of speaker's equipment transmission；
The judgment module judged for the sequence number to the data packet received；
For when sequence number interrupts, modify to the sequence number of the data packet after at interruption, so that modification
The continuous modified module of the sequence number of data packet afterwards；
For delivering a packet to the sending module of receiving device.
The foregoing is merely the preferred embodiments of the application, not to limit the application, all essences in the application
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the application protection.
