Fig. 2 is a kind of method flow diagram of adjustment session parameter according to another exemplary embodiment, this Embodiment is used to be illustrated in terminal in the method for the adjustment session parameter, the adjustment session parameter Method can include following steps：

In step 201, in communication process, the speech quality parameter in preset duration is obtained.

In voice call process is realized, terminal needs to consult session parameter with Correspondent Node, for example, it is desired to Consult the size of codec sample rate or used coded format etc..At present, terminal initially set up it is logical Session parameter is consulted during words with Correspondent Node, also, the session parameter no longer changes in communication process.

But because terminal is likely to constantly moving in communication process, for example, terminal be likely to from The strong region of network signal is moved to the region of network signal difference, in this case, above-mentioned to establish call When the session parameter that consults with Correspondent Node be likely to that current call demand can not be adapted to, so as to Voice distortion can be caused, such as, call is intermittent etc..

Therefore, in the disclosed embodiments, during call, terminal obtains the call in preset duration Mass parameter, and the speech quality parameter is based on, judge whether to need to be adjusted current session parameter, In this way, terminal is different according to the speech quality parameter, the session parameter can be dynamically adjusted so that the call Parameter can adapt in current call demand.

Wherein, the speech quality parameter includes any of packet loss and network signal intensity, and the packet loss is Refer to the ratio that lost data packets quantity in transmitting audio data packet procedures accounts for VoP quantity.

Wherein, above-mentioned preset duration can be by user's self-defined setting according to the actual requirements, can also be by terminal Default setting, the embodiment of the present disclosure are not limited this.

It should be noted that in the disclosed embodiments, be only with the speech quality parameter include packet loss and Illustrated exemplified by any of network signal intensity, in another embodiment, the speech quality parameter may be used also Not limited this including other parameters, the embodiment of the present disclosure.

In step 202, based on the speech quality parameter, determined from multiple default session parameters logical with this Talk about the default session parameter of mass parameter matching.

Wherein, based on the speech quality parameter, determine to join with the speech quality from multiple default session parameters The default session parameter of number matching can include following any possible implementation：

First way：The speech quality parameter is based on by the terminal oneself, from multiple default session parameters It is determined that the default session parameter matched with the speech quality parameter.Wherein, in this kind of implementation, the end The plurality of default session parameter is previously stored with end.

The second way：The terminal will send parameter acquiring message to equipment of the core network, the parameter acquiring message The speech quality parameter is carried, the parameter acquiring message is used to indicate that the equipment of the core network leads to from the plurality of preset The default session parameter matched with the speech quality parameter is determined and returned in words parameter, is received the core net and is set The parameter adjustment message that preparation is sent, parameter adjustment message carrying match default logical with the speech quality parameter Parameter is talked about, the parameter adjustment message is used to indicate that the terminal is default logical based on what is matched with the speech quality parameter Parameter is talked about, current talking parameter is adjusted.

In this kind of implementation, the equipment of the core network is previously stored with the plurality of default session parameter, terminal After sending parameter acquiring message to the equipment of the core network, the equipment of the core network is from the plurality of default session parameter It is determined that the default session parameter matched with the speech quality parameter, and the default session parameter based on determined by, Parameter adjustment message is generated, afterwards, the parameter adjustment message is sent to the terminal, phase by the equipment of the core network Ying Di, it is pre- determined by extraction from the parameter adjustment message after the terminal receives the parameter adjustment message If session parameter.

Wherein, in a kind of possible implementation, the parameter adjustment message can be sent by specified protocol To the terminal, wherein, the specified protocol include SIP or RTCP (Real Time Transport Control, RTCP Real-time Transport Control Protocol).

It should be noted that in above two implementation, terminal and equipment of the core network lead to from multiple preset It is similar with the specific implementation process of the default session parameter of speech quality parameter matching to talk about determination in parameter, under Introduction is made a distinction in text not to this.

In addition, it is necessary to explanation, in the disclosed embodiments, be only with the specified protocol include SIP or Illustrated exemplified by RTCP, in another embodiment, the specified protocol can also include other agreements, this public affairs Embodiment is opened not limit this.

Wherein, above-mentioned multiple default session parameters are included at least one in codec sample rate and coded format It is individual.Wherein, when the plurality of default session parameter is simultaneously including the codec sample rate with the coded format, Terminal can be adjusted to the codec sample rate and the coded format simultaneously, can also be only to the volume solution Code any of device sample rate and the coded format are adjusted.

Wherein, it is different according to speech quality parameter, it is above-mentioned to be based on the speech quality parameter, lead to from multiple preset The default session parameter for determining to match with the speech quality parameter in words parameter can include following (1)-(2) It is any in implementation：

(1), when this, which presets session parameter, includes lost data packets data, based on the speech quality parameter, The default session parameter for determining to match with the speech quality parameter from multiple default session parameters can be included such as It is any in lower a-b implementations：

A, when the speech quality parameter includes packet loss, and the packet loss is more than or equal in the preset duration During the first predetermined threshold value, the in the plurality of default session parameter first default session parameter is defined as and the call The default session parameter of mass parameter matching, the first default session parameter include minimum codec sample rate With it is at least one in AMR (Adaptive Multi Rate, AMR) coded format.

In this kind of implementation, when packet loss is more than or equal to the first predetermined threshold value in preset duration, then The network signal for illustrating to be likely to current is poor, in this case, if using larger codec Sample rate or complex coded format, and for example, EVS (Enhanced Voice Services, it is enhanced Voice call service), then the data volume transmitted will be very big, will cause the bit error rate high in transmitting procedure, from And causing the quantity of packet loss packet more, the easy distortion of voice, therefore, in this case, terminal is led to Frequently with less codec sample rate, or better simply coded format, or less volume is used simultaneously Decoder sample rate and better simply coded format, that is to say, terminal is detecting packet loss in preset duration Inside it is more than or equal to the first predetermined threshold value, the first default session parameter is defined as and the speech quality parameter The default session parameter matched somebody with somebody.

Conversely, when the packet loss is less than first predetermined threshold value in the preset duration, will be the plurality of default The second default session parameter is defined as the default session parameter matched with the speech quality parameter in session parameter, The second default session parameter includes maximum codec sample rate and enhanced voice call service EVS is encoded It is at least one in form.

It that is to say, when the packet loss is less than first predetermined threshold value in the preset duration, illustrate that network is believed Number preferably, in this case, terminal can use larger codec sample rate, more complicated coding Form, to reach the effect of high definition voice call.

Wherein, above-mentioned first predetermined threshold value can be by user's self-defined setting according to the actual requirements, can also be by Terminal default setting, the embodiment of the present disclosure are not limited this.

B, when the speech quality parameter includes packet loss, from multiple first preset ranges, when determining that this is default The first preset range in length residing for packet loss, from multiple default session parameters, determine in the preset duration Session parameter is preset corresponding to the first preset range residing for packet loss, it is true that session parameter is preset by determined by It is set to the default session parameter matched with the speech quality parameter.

Wherein, the plurality of first preset range can be by user's self-defined setting according to the actual requirements, can also By terminal default setting, the embodiment of the present disclosure is not limited this.

Compared with above-mentioned a implementations, in this kind of implementation, packet loss situation is divided into multiple Scope, correspondingly, the session parameter also include it is multiple, using the session parameter include codec sample rate as Example, in this case, the codec sample rate not only only include minimum codec sample rate and most Big codec sample rate, for example, for packet loss it is larger in the case of, the codec sample rate can be with Including multiple smaller codec sample rates, for example, the codec sample rate can include 500Hz, 1000Hz, 1500Hz and 2000Hz, terminal are selected from the plurality of smaller codec sample rate with being somebody's turn to do Codec sample rate corresponding to the first preset range in preset duration residing for packet loss, and will be selected Codec sample rate is defined as the session parameter matched with the speech quality parameter.

Similarly, when packet loss is smaller in the preset duration, the codec sample rate includes multiple larger volumes Decoder sample rate, in this case, it is determined that the process of the session parameter matched with the speech quality parameter It is similar to the above, it is not detailed herein.

In addition, in this kind of implementation, when the session parameter includes coded system, the coded system also may be used So that including multiple, the principle that its principle includes codec sample rate with above-mentioned session parameter is similar, here not It is described in detail again.Certainly, the coded system can also only include AMR and two kinds of EVS, in such case Under, session parameter can be adjusted with reference to multiple codec sample rates, the embodiment of the present disclosure to this not Limit.

(2), when this, which presets session parameter, includes network signal intensity, based on the speech quality parameter, from It is as follows to determine that the default session parameter matched with the speech quality parameter can include in multiple default session parameters It is any in c-d implementations：

C, when the speech quality parameter includes the network signal intensity, and the network signal intensity is when this is preset When being more than or equal to the second predetermined threshold value in long, by the in the plurality of default session parameter second default session parameter It is defined as the default session parameter matched with the speech quality parameter, the second default session parameter includes maximum It is at least one in codec sample rate and EVS coded formats.

Conversely, when the network signal intensity is less than second predetermined threshold value in the preset duration, this is more The first default session parameter is defined as the default call matched with the speech quality parameter in individual default session parameter Parameter, the first default session parameter are included at least one in minimum codec sample rate and AMR coded formats It is individual.

Wherein, the principle is similar with the principle in above-mentioned a implementations, is not detailed herein.

Wherein, above-mentioned second predetermined threshold value can be by user's self-defined setting according to the actual requirements, can also be by Terminal default setting, the embodiment of the present disclosure are not limited this.

D, when the speech quality parameter includes network signal intensity, from multiple second preset ranges, it is determined that The network signal intensity the second preset range residing in the preset duration, from the plurality of default session parameter In, determine to preset call corresponding to the network signal intensity the second preset range residing in the preset duration Parameter, the default session parameter that identified default session parameter is defined as matching with the speech quality parameter.

Wherein, the plurality of second preset range can also may be used by user's self-defined setting according to the actual requirements Not limited this by terminal default setting, the embodiment of the present disclosure.

Wherein, the principle is similar with the principle in above-mentioned b implementations, is not detailed herein.

It should be noted that only it is to use AMR to compile when speech quality is poor in the disclosed embodiments Code form, when speech quality is preferable using being illustrated exemplified by EVS coded formats, in another embodiment, For above-mentioned two situations, other coded formats can also be respectively adopted, the embodiment of the present disclosure is not limited this It is fixed.

In addition, it is necessary to explanation, is wrapped with the plurality of default session parameter in the disclosed embodiments Include it is at least one in codec sample rate and coded format exemplified by illustrate, in another embodiment, should Each default session parameter can also include other parameters, the embodiment of the present disclosure pair in multiple default session parameters This is not limited.

In step 203, it is identified default session parameter by current talking parameter adjustment, and passes through finger Determine agreement default session parameter by determined by send to Correspondent Node.

Wherein, identified default session parameter is sent to the specific implementation of Correspondent Node by specified protocol Process can include：Terminal can be added in the specific field of the specified protocol determined by session parameter, Or current session parameter is revised as identified session parameter in the specific field, and pass through biography The defeated specified protocol, default session parameter is carried to Correspondent Node by determined by.

For example, when the specified protocol includes SIP, terminal can be in the SDP (Session in the Session Initiation Protocol Description Protocol, Session Description Protocol) in current session parameter is revised as identified call Parameter, and sent by the Session Initiation Protocol to the Correspondent Node.

In addition, it is necessary to explanation, in embodiments of the present invention, be only with communication process by the terminal The speech quality parameter in preset duration is obtained, and is based on the speech quality parameter, from multiple default call ginsengs Illustrated exemplified by the default session parameter for determining to match with the speech quality parameter in number, in another embodiment In, can also by signal intensity of the equipment of the core network based on cell where present terminal, it is determined that with the current end The session parameter of the signal intensity matching of cell where end, afterwards, this is sent to by identified session parameter Terminal, to indicate that terminal session parameter based on determined by is adjusted to current talking parameter.
