Description

A kind of method, apparatus and system of communication negotiation

Technical field

The present invention relates to the communication technology more particularly to a kind of method, apparatus and system of communication negotiation.

Background technology

In the communication path of voice communication, needs to carry out coding-decoding operation twice to voice data, grade can be referred to as Binding decoding process, i.e. an encoding and decoding are completed by mobile phone terminal side, another secondary encoding and decoding by network side codec (TC, Transcoder it) completes.But by speech encoding and decoding process twice in this way, the propagation delay time of voice data is will increase, simultaneously The accuracy that voice data can also be damaged, causes the reduction of voice quality.In order to avoid the generation of the above situation, third generation cooperation Partnership Program (3GPP, 3rd Generation Partnership Project) group is woven in the agreement of 3GPP28.062 versions It proposes one kind to exempt to cascade coding-decoding operation (TFO, Tandem Free Operation) scheme, can remove network side TC's from Encoding-decoding process, on entire communication path only to coding-decoding operation of voice data row, in this way can to avoid because Cascade code encoding/decoding mode is lost caused by voice data.

Currently, TFO connections establish process and include mainly：As mobile switching centre (MSC, Mobile Switching Center) the A interfaces between base station controller (BSC, Base Station Controller) be time-multiplexed (TDM, Time Division Multiple Access) mode transmission data when, A interfaces transmission be 64kb/s pulse code Modulate (PCM, Pulse Coded Modulation) data；When both call sides are using the encoding and decoding speech being mutually compatible with, then TFO connections can be established.

Before TFO connections foundation, both call sides need to carry out TFO negotiations by interaction, if negotiation result is call When the currently used coding mode matching of both sides, that is, illustrate the currently used compatible encoding and decoding speech type of both call sides or Both call sides have used compatible configuration under identical encoding and decoding speech type, then both call sides just establish TFO connections；It is no Then, it if the currently used coding mode of both call sides mismatches, needs to hand over by TFO code sets for mismatch situation Mutually solution process is mismatched to carry out TFO.

Above-mentioned TFO mismatches solution process：Both call sides send interaction request message to opposite end respectively, such as TFO_REQ_L message or Con_Req frames；Wherein, interaction request message include encoding and decoding speech set that local terminal is supported and Relevant configured parameter.After both call sides receive interaction request message, alternate acknowledge message, such as TFO_ACK_ are sent to opposite end L message or Con_Ack frames；Wherein, interaction request message includes the encoding and decoding speech set and relevant configuration that local terminal is supported Parameter.The encoding and decoding row collection and configuration ginseng that local terminal is supported can be informed to opposite end by above-mentioned interactive process both call sides Number so as to provide the public encoding and decoding speech type and configuration parameter that one can carry out TFO, and reports BSC.With Afterwards, both call sides set the encoding and decoding speech type that local terminal uses to public encoding and decoding speech type and configuration parameter, After the setup, both call sides re-start TFO negotiations, and establish TFO connections.If public voice is not present in both call sides Code/decode type, then both call sides will be abandoned establishing TFO connections.

During TFO mismatches solution, when the encoding and decoding for the support that TFO_REQ_L/TFO_ACK_L message includes When row are concentrated comprising adaptive multi-rate (AMR, Adaptive Multi-Rate) encoding and decoding speech, it can be added by attribute head The form for configuring extension blocks carries AMR configuration parameters；Wherein, AMR configure parameter may include activation rate set (ACS, Active Codec Set), support rate set (SCS, Supported Codec Set), activation rate concentrate encoding and decoding mould The maximum number (MACS, Maximum number of Codecs Modes in the Active Codec Set) and branch of formula Hold model-based optimization (OM, Optimisation Mode supported).In addition it is also possible to special by being used in only attribute head Coding shows the form of AMR preferred dispositions and configures parameter to carry AMR, and carrying AMR configures the mode only TFO the 5th of parameter Version Version 5 and more highest version can be supported.

When adding the form of configuration extension blocks to carry AMR configuration parameters by attribute head, do not support what ACS was changed in local terminal In the case of, if the AMR sound-types of local terminal, as sound-type alternative rather than being being currently used, local terminal is sent To may not indicate OM in the message of opposite end；Due to when establishing TFO, the highest priority of AMR encoding and decoding, if opposite end is supported to compile It also includes AMR code/decode types that decoded row, which are concentrated, then both call sides in the preferred sound-type for negotiating can to establish TFO and When configuration, the preferential negotiation and judgement for carrying out AMR encoding and decoding.And negotiates encoding and decoding and need to use the OM values at both ends, OM values Difference, negotiation flow is also different, and the result of negotiation is likely to different.

It is assumed that TFO mismatches the value that solution process gets opposite end OM, can be built by the interaction of TFO code sets at this time The preferred disposition of vertical TFO simultaneously reports BSC；Then, non-present is modified to AMR code/decode types using one end of AMR encoding and decoding, that It can carry out establishing the negotiations process of TFO, and the ACS blocks in negotiation message indicate OM values, then according to both ends reality OM values hold consultation and judge, it is likely that will appear and the inconsistent situation of the negotiation result of BSC is reported to occur, to lead It is that TFO is not established that the negotiation result of TFO is established in cause, then causes new TFO and mismatches solution process.That is, AMR voices Encoding and decoding are held consultation in the other end as alternative encoding and decoding speech at one end as currently used encoding and decoding speech When, OM values may be inconsistent, may also be inconsistent so as to cause the result of negotiation, eventually leads to TFO and mismatches solution process It is middle to shake, and cause repeatedly hold consultation optimizing code and decode and configure and report, TFO connections cannot establish always, drop Low speech quality.

S101：When sending ending equipment supports AMR encoding and decoding speech and the unused AMR encoding and decoding speech of currently transmitted end equipment When, the filling mode of SCS extension blocks in interaction message is determined according to preset decision plan；

Wherein, the interaction message is to carry out TFO code set interaction request message or friendship during TFO mismatches solution Mutual response message；During specific implementation, interaction request message is preferably TFO_REQ_L message, and correspondingly, alternate acknowledge disappears Breath is preferably TFO_ACK_L message.

Illustratively, the filling mode that SCS extension blocks in interaction message are determined according to preset decision plan, can be with Including：

AMR encoding and decoding speech is currently not used in sending ending equipment, and AMR encoding and decoding speech is only as alternative voice Code/decode type, and when sending ending equipment support AMR encoding/decoding mode complete or collected works：

If sending ending equipment OM value characterization do not support ACS to change, sending ending equipment in the interaction message with The form of attribute head and SCS extension blocks carries AMR and configures parameter, and sending ending equipment by the ACS of configuration substitute SCS fill to SCS extension blocks in the interaction message fill other configurations parameter to the interaction message according to preset filling Strategy；

If sending ending equipment OM values characterization supports ACS changes, and need not carry TFO version extension blocks, then transmitting terminal Equipment omits attribute head and SCS extension blocks in the interaction message；

If sending ending equipment OM values characterization supports ACS changes, and when needing to carry TFO version extension blocks, then transmitting terminal Equipment carries AMR in the form of attribute head and SCS extension blocks in the interaction message and configures parameter, and sending ending equipment will All configuration parameters are filled according to the filling Strategy to the interaction message.

It should be noted that since AMR includes full rate (FR, Full Rate) pattern and half rate (HR, Half Rate) pattern；So for full rate AMR (FR_AMR), AMR encoding/decoding mode complete or collected works is supported to indicate that 8 kinds of patterns are all supported； For half rate AMR (HR_AMR), 6 kinds of patterns of AMR encoding/decoding modes complete or collected works is supported all to support.In addition, sending ending equipment can OM values are supported ACS changes for 1 to characterize, ACS is not supported to change to characterize for 0 OM values.In addition, preset filling Strategy is specifically as follows the description according to TFO agreements, and sending ending equipment is by the corresponding initial data of configuration parameter indicated by BSC (such as：OM, MACS, ACS or SCS etc.) it is directly filled into interaction message.

Illustratively, the filling mode that SCS extension blocks in interaction message are determined according to preset decision plan, may be used also To include：

AMR encoding and decoding speech is currently not used in sending ending equipment, and AMR encoding and decoding speech is only as alternative voice Code/decode type, and sending ending equipment does not support AMR encoding/decoding mode complete or collected works, and need with the shape of attribute head and SCS extension blocks When formula carries AMR configuration parameters：

If the value characterization of sending ending equipment OM does not support ACS to change, the ACS of configuration is substituted SCS by sending ending equipment Filling fills other configurations parameter to the friendship according to preset filling Strategy to the SCS extension blocks in the interaction message Mutual message；

If sending ending equipment OM values characterization supports ACS changes, sending ending equipment is by all configuration parameters according to default Filling Strategy fill to the interaction message.

It should be noted that in this example, it is preferable that the carrying AMR in the form of attribute head and SCS extension blocks is needed to match It sets parameter and can extend parameter PAR_Sel in the block by attribute head and be set to 1 and characterized.

Illustratively, the method further includes：

When AMR encoding and decoding speech is being currently used in sending ending equipment, sending ending equipment by all configuration parameters according to Preset filling Strategy is filled to the interaction message.

S102：Interaction message after sending ending equipment completes filling is sent to opposite end.

It is to be appreciated that need the interaction by message come the process of holding consultation since TFO mismatches solution process, because This, any one end for sending interaction message is the sending ending equipment described in the present embodiment, and receives interaction message accordingly One end is then the opposite end of sending ending equipment.

For technical solution shown in FIG. 1, during specific implementation, referring to Fig. 2, may include：

S201：Whether sending ending equipment judges whether to support AMR and currently be used according to the configuration information of itself AMR；If support AMR and AMR is not currently used, S203 is gone to；Otherwise S202 is gone to；

S202：Sending ending equipment is filled parameter is configured to interaction message according to TFO agreements；

S203：Sending ending equipment determines SCS extension blocks whether are carried in interaction message according to preset first decision condition； If it is, going to S204；Otherwise, S207 is gone to；

Specifically, the first decision condition may include：Support AMR encoding/decoding modes, OM values, TFO versions.

If sending ending equipment OM values are 1 (support ACS change), and when without carrying TFO version extension blocks, then can save Slightly attribute head and SCS extension blocks；Other situations need to carry attribute head, and PAR_Sel carries SCS extension blocks when setting 1.

S204：Sending ending equipment determines whether to fill ASC to SCS extension blocks according to preset second decision condition；Such as Fruit is to go to S206；Otherwise S205 is gone to；

Specifically, if sending ending equipment supports AMR encoding/decoding mode complete or collected works, and sending ending equipment OM values (are not supported for 0 ACS is changed), then attribute head and SCS extension blocks can not be omitted, needs to substitute SCS with the ACS that sending ending equipment local terminal configures；If AMR codec pattern complete or collected works are not supported, and (i.e. attribute head extends PAR_Sel in the block in the form of attribute head and SCS extension blocks When being set to 1) carrying AMR configurations parameter, if sending ending equipment OM values 0, the ACS that sending ending equipment local terminal configures is needed to substitute SCS.Other situations, SCS configurations are filled according to TFO agreements 28.062.

S205：SCS original parameter values are filled the SCS extension blocks into interactive information by sending ending equipment according to TFO agreements, Go to S207；

S206：ACS is filled the SCS extension blocks into interactive information by sending ending equipment, goes to S207；

S207：Sending ending equipment fills residue configuration parameter into interactive information according to TFO agreements.

Referring to Fig. 3, it illustrates a kind of method of communication negotiation provided in an embodiment of the present invention, this method is applied to TFO The receiving device of interaction message during solving is mismatched, this method may include：

S301：Receive the interaction message that opposite end is sent；

It should be noted that the receiving device described in the present embodiment is to receive interaction during TFO mismatches solution to disappear Any one end equipment of breath, therefore, corresponding one end for sending interaction message are then the opposite end of receiving device.

Specifically, the interaction message be TFO mismatch solve during carry out TFO code set interaction request message or Alternate acknowledge message；During specific implementation, interaction request message is preferably TFO_REQ_L message, correspondingly, alternate acknowledge Message is preferably TFO_ACK_L message.

S302：When determining opposite end support AMR encoding and decoding speech using interaction message and carrying out TFO mismatch solution processes, According to the configuration parameter and preset acquisition strategy filled in the interaction message, the OM values of opposite end are obtained.

Illustratively, described according to the configuration parameter filled in the interaction message and preset acquisition strategy, it obtains The OM values of opposite end are taken, including：

When AMR encoding and decoding speech is currently not used in opposite end, and AMR encoding and decoding speech is only as alternative voice coder solution When code type：

If the attribute head in interaction message is extended parameter PAR_Sel values instruction in the block and needs to be extended with attribute head and SCS When the form of block carries AMR configuration parameter (for example being 1), then the value characterization of receiving terminal setting opposite end OM supports ACS changes；

If not carried after the attribute head extension parameter PAR_Sel values instruction attribute head extension blocks in the block in interaction message attached When encoding and decoding attribute extension block (for example being 0) added, then receiving terminal extracts the original value of OM parameters according to TFO agreements；

If attribute head extension blocks are not present in interaction message, the value characterization that receiving terminal sets opposite end OM supports ACS to become More.

When AMR encoding and decoding speech is being currently used in opposite end, it is original that receiving terminal directly acquires OM from the interaction message Value.

S303：The other configurations parameter in addition to OM values is extracted according to preset extraction strategy；

Specifically, other configurations parameter can be extracted or be supplemented according to the extraction process of TFO agreement defineds, such as SCS supplements are complete or collected works, and the present embodiment is not especially limited this.

For technical solution shown in Fig. 3, during specific implementation, referring to Fig. 4, may include：

S401, receiving device according to the configuration of opposite end, judge opposite end whether support AMR types and it is current whether Use AMR sound-types.

If S402, opposite end are not when AMR code/decode types are not used and only supporting AMR code/decode types, receiving terminal is set The standby configuration parameter extracted according to TFO agreements in interaction message.

If AMR encoding and decoding speech is not used currently in S403, opposite end, and AMR encoding and decoding speech is only as alternative Encoding and decoding speech type, then receiving device judge in interaction message with the presence or absence of description AMR configuration attribute head and PAR_ The value of Sel.

If there are attribute head and PAR_Sel=0, receiving device to extract OM according to TFO agreements in S404, interaction message Parameter is configured, S406 is gone to.

If omitting PAR_Sel=1 in attribute head or attribute head in S405, interaction message, receiving device is by opposite end OM values are assigned a value of 1, go to S406.

S406, the receiving device remaining configuration parameter in opposite end other than extraction OM in interaction message by TFO agreements.

By the specific implementation process of Fig. 1 and technical solution shown in Fig. 3 and corresponding technical solution, when TFO is mismatched Solving both sides interactive in the process does not support ACS to change, and one end of interaction supports AMR encoding and decoding speech when non-present makes When with AMR encoding and decoding speech, interaction message is filled by substituting SCS with the ACS of configuration, and do not show OM in extracting message Opposite end OM values are set when value as 1 so that when AMR encoding and decoding speech is also supported in opposite end, TFO can be allowed to mismatch solution process It is consistent to negotiate the TFO negotiation results after carrying out optimizing code and decode and switching according to optimizing code and decode, to more efficiently Preferred encoding and decoding speech type and configuration parameter are negotiated, avoids TFO from mismatching and solves to shake in the process, improve and establish The success rate of TFO connections promotes speech quality.

The specific implementation process of scheme and technical solution in view of the above technology, it is also necessary to explanation, when interaction both ends When not supporting ACS to change, and A held to support AMR sound-types and non-present use, and carrying out TFO mismatch solution processes：

If other end B also supports AMR sound-types and is currently not used, end A can be filled by flow shown in Fig. 2 AMR configuration datas, and the configuration data of the flow extraction end B by Fig. 4 descriptions, hold the AMR configuration datas of B directly to take it BSC is configured, and operation later determines that encoding and decoding judge whether that the preferred disposition of TFO can be established；

If other end B also supports AMR sound-types and is being currently used, then being extracted on both ends and negotiating to establish The AMR configuration datas of some differences of the flow of TFO preferred dispositions, opposite end A are filled by the flow that Fig. 2 and Fig. 4 is described and extraction, The AMR configuration datas of local terminal B directly take its BSC configurations, but the result that both ends are negotiated is consistent；

If other end B does not support AMR sound-types, when negotiating to establish the preferred disposition of TFO on holding B, the AMR of A is held to match It sets data to fill and extract by the flow that Fig. 2 and Fig. 4 is described, holds the AMR of B to configure parameter and directly take its BSC configurations, root Preferred encoding and decoding speech type is found according to the encoding and decoding priority for establishing TFO.

It can thus be seen that previous embodiment will not be influenced negotiates whether TFO can build with one end of AMR is not supported It is vertical.

Based on the identical technical concept of previous embodiment, referring to Fig. 5, it illustrates a kind of hairs provided in an embodiment of the present invention Sending end equipment 50 may include：Fill module 501 and sending module 502；Wherein,

The filling module 501, for when the support adaptive multi-rate AMR encoding and decoding speech of sending ending equipment 50 and currently When AMR encoding and decoding speech is not used in the sending ending equipment 50, determines according to preset decision plan and to be supported in interaction message The filling mode of rate set SCS extension blocks；Wherein, the interaction message is to carry out TFO coded sets during TFO mismatches solution Close interaction request message or alternate acknowledge message；

The sending module 502 is sent to opposite end for the interaction message after completing filling.

In the above scheme, the filling module 501, is used for：
