Fig. 3 is the flow chart for the communication means that one embodiment of the application provides, as shown in figure 3, the method for the present embodiment can To include:

S301, the network equipment determine the size for needing to adjust the jitter buffer of terminal.

S302, the network equipment send the first instruction information to the terminal.Correspondingly, the terminal receives the net The first instruction information that network equipment is sent.

S303, the terminal adjust the size of the jitter buffer of the terminal according to the first instruction information.

The network equipment in the present embodiment is the wireless access network equipment of terminal attachment.The jitter buffer of terminal can be used for The delay variation of data packet is eliminated, that is, eliminates the transmission time delay difference of data packet (such as VoP), if delay variation increases, Then the jitter buffer of corresponding terminal should also tune up, if delay variation is reduced, the jitter buffer of corresponding terminal is also answered It turns down, therefore, the adjustment needs of the size of jitter buffer guarantee to reduce in the case where completely eliminating delay variation end-to-end Propagation delay time.In the present embodiment, the network equipment determines the big of the jitter buffer (jitter buffer) for needing to adjust terminal It is small, the first instruction information then is sent to terminal, which is used to indicate the big of terminal adjustment jitter buffer It is small.Correspondingly, terminal receives the first instruction information of network equipment transmission, and adjusts the terminal according to the first instruction information Jitter buffer size.Such as: the size of its jitter buffer can be increased with instruction terminal, alternatively, instruction terminal is reduced The size of its jitter buffer.

The present embodiment is just sent to terminal after determining the size for the jitter buffer for needing to adjust terminal by the network equipment First instruction information；Terminal just adjusts the shake of the terminal after receiving the first instruction information according to the first instruction information The size of buffer.The terminal of the present embodiment by being counted to data packet received in a period of time in addition to that can be determined Except the size for whether adjusting jitter buffer, its jitter buffer can also be adjusted according to the first instruction information is received Size, so as to quickly adjust the size of jitter buffer, to adapt to the communication condition between the network equipment and terminal in time Variation improves communication quality, further improves voice quality, promotes user experience.

In some embodiments, in a kind of possible implementation of above-mentioned S301, the network equipment is determining that the network sets When the standby air interface transmission time delay between terminal changes, the size for needing to adjust the jitter buffer of terminal is determined.Wherein, The received data packet of the terminal is via the air interface transmission between the network equipment and terminal, therefore, between the network equipment and terminal Air interface transmission time delay when changing, the propagation delay time of the data packet can also change, to cause the time delay of data packet Shake, so current embodiment require that adjusting the size of the jitter buffer of terminal in time.If the network equipment determines air interface transmission Prolong elongated, can delay variation be elongated, then network equipment determination needs the size by the jitter buffer of terminal to tune up, accordingly Ground, the first instruction information are used to indicate the size for increasing jitter buffer, and terminal increases the terminal according to the first instruction information The size of jitter buffer can make delay variation reduce, then network is set if the network equipment determines that the time delay of air interface transmission shortens Standby determination needs the size by the jitter buffer of terminal to turn down, and correspondingly, it is slow that the first instruction information is used to indicate reduction shake The size of storage, terminal reduce the size of the jitter buffer of the terminal according to the first instruction information.

Optionally, the network equipment is when determining that the link-quality of eating dishes without rice or wine between the network equipment and terminal changes, or Person, for the network equipment when the load for determining the network equipment changes, the network equipment can determine the network equipment and terminal Between air interface transmission time delay change.

In some embodiments, the network equipment is determining that the link-quality of eating dishes without rice or wine between the network equipment and terminal becomes When change, the size for needing to adjust the jitter buffer of terminal is determined.Wherein, the link matter of eating dishes without rice or wine between the network equipment and terminal Amount changes, and influences whether the air interface transmission time delay between the network equipment and terminal, so that the time delay for influencing data packet is trembled It is dynamic, and then need to adjust the size of the jitter buffer of the terminal.If the link-quality change of eating dishes without rice or wine between the network equipment and terminal Difference, then network equipment determination need the size by the jitter buffer of terminal to tune up.If eating dishes without rice or wine between the network equipment and terminal Link-quality improves, then network equipment determination needs the size by the jitter buffer of terminal to turn down.Therefore, the net of the present embodiment Network equipment can notify the size of terminal adjustment jitter buffer in time according to the variation of the quality for link of eating dishes without rice or wine.

In some embodiments, when the load for determining the network equipment changes, determination needs to adjust the network equipment The size of the jitter buffer of terminal.Wherein, the load of the network equipment changes, influence whether the network equipment and terminal it Between air interface transmission time delay, to influence the delay variation of data packet, and then need to adjust the jitter buffer of the terminal Size.If the load of the network equipment becomes weight, network equipment determination needs the size by the jitter buffer of terminal to tune up.If net The load of network equipment lightens, then network equipment determination needs the size by the jitter buffer of terminal to turn down.Therefore, the present embodiment The network equipment can according to the load of the network equipment variation in time notice terminal adjustment jitter buffer size.

Wherein, above-mentioned first instruction information, which can for example be carried, sends in different signalings in the network equipment to terminal, such as: RRC information or MAC CE or switching command.

In some embodiments, above-mentioned first instruction information can carry the RRC information sent in the network equipment to terminal Or in MAC CE.Therefore, the network equipment of the present embodiment can carry the first instruction information by RRC information or MAC CE To notify terminal to adjust the size of the jitter buffer of terminal.

In some embodiments, above-mentioned first instruction information can also carry the switching life sent in the network equipment to terminal In order.Such as: in the source base station that handoff scenario, the network equipment are adhered to as the terminal, once trigger terminal switching, terminal Data transmission will be interrupted, terminal will be switched off the connection with source base station, establish the new connection with target BS.Only work as terminal After accessing target BS, the data transmission of terminal could restore, to increase the air interface transmission time delay of terminal data, correspondingly The delay variation of data transmission is increased, and then needs to adjust the size of the jitter buffer of the terminal.The network equipment determines eventually When end needs to switch, the network equipment sends switching command to terminal, and the first instruction information is carried in the switching command and is used to Instruction terminal increases the size of its jitter buffer；Correspondingly, after terminal receives switching command, according to what is carried in the message First instruction information, increases the size of the jitter buffer of terminal.Alternatively, the network equipment sends switching command to terminal, this is cut It changes in order and does not carry the first instruction information；Correspondingly, after terminal receives switching command, it is known that oneself need to be implemented switching behaviour Make, therefore voluntarily increases the size of its jitter buffer.

It in some embodiments, include the information of the first value in the first instruction information, the network equipment passes through the letter of the first value Breath carrys out the size how instruction terminal adjusts the jitter buffer of terminal, and correspondingly, terminal can be adjusted according to the information of the first value The size of the jitter buffer of whole terminal.Wherein, the information of the first value can indicate the size of the first value；In different embodiments In, which can indicate the size of the first value using different indicating modes, such as can be indicated with bit information The size of one value.

In one possible implementation, the first value is the size of jitter buffer adjusted, i.e. the network equipment is logical It crosses the first value instruction terminal to adjust the size of the jitter buffer of terminal to the first value, it is believed that the first value is adjustment terminal Jitter buffer order of magnitude.Wherein, which can be the network equipment according between the network equipment and terminal What air interface transmission Delay Variation situation determined.Such as: the size of the jitter buffer of terminal before terminal executes above-mentioned S303 For D1, the first value is, for example, D2, terminal when executing S303 specially terminal by the size of the jitter buffer of terminal by D1 tune Whole is D2.Such as: if the air interface transmission time delay between the network equipment and terminal extends, D2 is greater than D1, if the network equipment and end Air interface transmission time delay between end shortens, then D2 is less than D1.Optionally, the terminal of the present embodiment is before executing S303 also to net Network equipment sends the information of the size of the jitter buffer of terminal, which is used to indicate the current size of jitter buffer (such as D1), herein when currently can referring to that terminal sends the information, the network equipment receives the jitter cache of terminal from terminal The information of the size of device, further according to the air interface transmission time delay between the information and the network equipment and terminal of the size of jitter buffer Situation of change, determine the size (such as D2) of the jitter buffer of terminal adjusted.

In alternatively possible implementation, the first value is the adjustment amount of jitter buffer, i.e. the network equipment passes through the The adjustment amount that one value instruction terminal adjusts the size of the jitter buffer of terminal is the first value, it is believed that the first value is that adjustment is whole The relative value size of the jitter buffer at end.Wherein, which can be the network equipment according between the network equipment and terminal Air interface transmission Delay Variation situation determine.Such as: the jitter buffer of terminal is big before terminal executes above-mentioned S303 Small is D1, and the first value is, for example, D2, terminal when executing S303 specially terminal by the size of the jitter buffer of terminal by D1+ D2 or D1-D2.Such as: D2 can be positive value, or negative value, if the air interface transmission time delay between the network equipment and terminal Extend, then D2 is positive value, is D1+D2 after the size adjustment of the jitter buffer of corresponding terminal, that is, increases jitter buffer Size；If the air interface transmission time delay between the network equipment and terminal shortens, D2 is negative value, the jitter buffer of corresponding terminal Size is adjusted to D1+D2, that is, reduces the size of jitter buffer.Alternatively, D2 is positive value, the first instruction information can also include Increase instruction or reduce instruction, if the air interface transmission time delay between the network equipment and terminal extends, the first instruction information is also It is indicated including increasing, is D1+D2 after the size adjustment of the jitter buffer of corresponding terminal, that is, increases the big of jitter buffer It is small；If the air interface transmission time delay between the network equipment and terminal shortens, the first instruction information further includes reducing instruction, corresponding whole The size of the jitter buffer at end is adjusted to D1-D2, that is, reduces the size of jitter buffer.

Fig. 4 is the flow chart for the communication means that another embodiment of the application provides, as shown in figure 4, the method for the present embodiment May include:

S401, terminal determine that the air interface transmission time delay between the terminal and the network equipment changes.

S402, the terminal adjust the size of the jitter buffer of the terminal.
