Background technology
DTX be global system for mobile communications (Global System for Mobile Communications, GSM) in order to reduce in system resource waste and the system control technology of disturbing and using.Its principle is to detect (VAD) technology through voice activation; Blocks of speech at every 20ms produces one group of threshold value in the time, be used to judge that the blocks of speech of next 20ms is speech or noise, when being judged as blocks of speech; System will carry out data by normal send mode (260bit/20ms) and transmit; When being judged as noise, then the speed with 260bit/480ms transmits the background noise (also claiming comfort noise) through coding, and the data volume that promptly transmits reduces greatly.
DTX comprises the opening and closing two states, and promptly system determines whether in communication process, to use this technology, and can be provided with respectively by uplink and downlink as required through the parameter setting.
In the gsm system; The Control Parameter of descending DTX mobile services switching centre (Mobile Service Switch Center, MSC) and base station controller (Base Station Controller exists in BSC); Only when parameter among both all is made as " unlatching " state; The DTX function just is activated, and any end is in " closing " state, and the DTX function all is not activated.
Descending DTX function is actually that (Base Transceiver Station, BTS) control code type transducer (TC) is accomplished by MSC, BSC and base station in gsm mobile communication system.MSC informs base station sub-system (Base Station Subsystem through the descending DTX sign Downlink DTX Flag (GSM 08.083.2.2.26) in assignment request ASSIGNMENT REQUEST (GSM 08.083.2.1.1) and handoff request HANDOVER REQUEST (GSM 08.083.2.1.8) message; BSS) whether can use descending DTX function; BSC activates in the CHANNELACTIVATION message at channel and informs whether BTS can use descending DTX function; BTS informs through the C17bit in the up trau frame (GSM 08.603.1&3.4&3.5&4.6.6.2) whether TC can use descending DTX function; When MSC and BSC allowed to use the DTX function simultaneously, descending DTX function just was activated.In case speech channel is set up in the current system, then the conversation in this BSC will remain the unlatching of descending DTX or close in a kind of state.
In the existing network, in order to improve wireless environment, disturb in the reduction system, most of mobile communication carriers have all adopted uplink and downlink DTX technology.When caller is the mobile subscriber, for descending DTX function, begin to end of conversation from called terminal ringing, link is in descending DTX opening all the time.
As mobile subscriber during as caller, existing DTX function all is in state of activation before end of conversation behind called terminal ringing.For normal speech behind the called off-hook, after opening, the DTX function can satisfy user's demand; But because the technology of DTX limitation, for music or song, it detects just has certain limitation, and its limitation mainly occurs in the ringing phase before the called off-hook.Current mobile operator and fixed-line telecom carrier all provide music tone ringer before called off-hook, be commonly called as " CRBT ".For some melody of comparatively releiving or song; The melodious bell change of tune that the DTX function causes caller to hear after opening gets intermittently serious with the noise sense; Influence client perception, reduced the satisfaction of user for service, close descending DTX function after user's perception obtained very significantly improving; But in case close descending DTX function, its influence is to disturb in the whole follow-up communication process and wasting of resources problem will further worsen.
In sum, owing to talking state is not judged in the call flow of prior art, when descending DTX function allow to be opened by system, the descending DTX function of the ringing phase before called party answer was just opened, and then services such as CRBT generation is had a strong impact on.

Embodiment 1:
Participate in judging called whether replying by TC, and to control descending DTX state according to the identification information of judged result and reception be opening or closed condition.Specifically comprise:
MSC is when call setup; Send identification information to BSC, identification information comprises: whether allow to use descending DTX function descending DTX identification information, show the type of call identification information of caller conversation or incoming call and show called whether replied reply identification information; This identification information is sent to BTS by BSC, is sent to TC by BTS again;
When using a DTX identification information of descending DTX function when TC receives permission, show the first type of call identification information of caller conversation and showing that first of called dont answer is replied identification information, the descending DTX state of control Calling Side is a closed condition; And showing calledly when having replied when the up trau frame that monitors the follow-up transmission of BTS, the descending DTX state of control Calling Side is an opening;
When TC received a DTX identification information and shows the second type of call identification information of incoming call, the descending DTX state of control callee side was an opening;
When TC received the 2nd DTX identification information that do not allow to use descending DTX function and the first type of call identification information, the descending DTX state of control Calling Side was a closed condition;
When TC received the 2nd DTX identification information that do not allow to use descending DTX function and the second type of call identification information, the descending DTX state of control callee side was a closed condition.
Take a concrete Signalling exchange example below:
MSC can judge that the user of A access circuit resource is caller incident or called event; Record in the type of call sign (Call_type_flag_msc); Call_type_flag_msc=0 representes the caller conversation; Be the first type of call identification information, Call_type_flag_msc=1 representes incoming call, is the second type of call identification information.MSC can monitor, write down called whether replying; When state changes, upgrade and reply sign Answer_flag_msc, Answer_flag_msc=0 representes called dont answer, is first and replys identification information; Answer_flag_msc=1 representes calledly to reply, is second and replys identification information.
MSC can pass to BSC with whether allowing to use DTX function, type of call sign (Call_type_flag_msc) and replying sign (Answer_flag_msc).
In concrete the application, MSC can transmit Downlink DTX Flag information through ASSIGNMENT REQUEST message and give BSS when call setup, wherein; Whether Downlink DTX Flag bit1 sign BSS can use descending DTX function (as prior art); Bit2 to bit8 is an idle bit, as an example, passes to BSC in order to realize the type of call sign and to reply sign; Can define bit2 again is Call_type_flag_msc, and bit3 is Answer_flag_msc.When Call_type_flag_msc=0, represent caller conversation, when Call_type_flag_msc=1, represent incoming call, when Answer_flag_msc=0, represent called dont answer, when Answer_flag_msc=1, represent calledly to reply.BSS system for having corresponding function can understand those information, and the BSS system that does not have a corresponding function can ignore it, is not affected.
BSC reception, deciphering, storage, updating call type identification (Call_type_flag_msc) and reply sign (Answer_flag_msc), and save as the type of call sign (Call_type_flag_bsc) of BSC side and reply sign (Answer_flag_bsc).
Whether BSC identifies (Call_type_flag_bsc) with type of call and replys sign (Answer_flag_bsc) and allow to use the sign DTXd of descending DTX function to send BTS to.
In concrete the application, when BSC activates transmission channel (TCH) through CHANNEL ACTIVATION message informing BTS, can transmit the DTXd parameter, inform whether allow to use descending DTX function (prior art).Wherein, The bit3 to bit8 of the 3rd eight bit byte (octet3) at DTXd place is reservation bit (bit) in the CHANNEL ACTIVATION message, does not use as yet at present, as an example; Pass to BTS in order to realize the type of call sign and to reply sign; Can define bit3 again is Call_type_flag_bsc, and definition bit4 is Answer_flag_bsc, can understand those information for the BTS with corresponding function; And the BTS system that does not have corresponding function can ignore it, is not affected.
Whether BTS identifies (Call_type_flag_bsc) with type of call and replys sign (Answer_flag_bsc) and allow to use the sign DTXd of descending DTX function to send TC to.
In the concrete practicality, BTS can transmit the DTXd parameter when TC sends trau frame; Inform whether allow to use descending DTX function (prior art); C18 to C21bit in the trau frame is idle bit, as an example, passes to TC in order to realize the type of call sign and to reply sign; Can define C18 again is Call_type_flag_bsc, and definition C19 is Answer_flag_bsc.
Whether TC opens descending TDX function according to the Call_type_flag_bsc, Answer_flag_bsc and the DTXd parameter decision that receive from up trau frame.Comprising following situation:
Situation one:
When TC receives Call_type_flag_bsc=0; Answer_flag_bsc=1; During DTXd=1 (the called situation of having replied of this kind generally is that the called party answer state of MSC record changed, promptly changes into called response status by called dont answer state after MSC switching or BSC switching had taken place in the calling procedure); Expression allows to use descending DTX function; For caller call flow and called is replied, then directly to control the descending DTX state of Calling Side be opening to TC, activates the descending DTX function of Calling Side.
Situation two:
When TC receives Call_type_flag_bsc=0, Answer_flag_bsc=0 is during DTXd=1 (this table shape has been generally and has exhaled the stage); Expression allows to use descending DTX function, is caller call flow and called dont answer, and then the descending DTX state of control Calling Side is a closed condition earlier; And the up trau frame that BTS sends monitored, (during when called dont answer, BTS sends Idle Speech Frame to TC when idle speech frame (Idle Speech Frame) converts normal language single frames (Speech Frame) into when the up trau frame of conversation; When BTS detects the ascending voice frame; To send out Speech Frame to TC, this signaling procedure is a prior art), judge and calledly reply; The descending DTX state of control Calling Side is an opening, activates descending DTX function.
Situation three:
When TC receives Call_type_flag_bsc=1, Answer_flag_bsc=1 or 0 is during DTXd=1; Expression allows to use descending DTX function, is the incoming call flow process, no matter then called current whether replying; All controlling the descending DTX state of callee side is opening, activates descending DTX function.
Other situation:
When TC receives DTXd=0, Call_type_flag_bsc=0, expression caller call flow and do not allow to use descending DTX function, no matter then called whether replying, the descending DTX state of control Calling Side is a closed condition;
When TC receives DTXd=0, Call_type_flag_bsc=1, expression incoming call flow process and do not allow to use descending DTX function, no matter then called whether replying, the descending DTX state of control callee side is a closed condition.
In the actual call communication process; No matter caller or called; All might sub-district switching, BSC switching or MSC switching etc. take place owing to moving, after switching, should make the target TC after switching also can control the open and close of descending DTX state according to current call state.
When comprising in the identification information that MSC that BSC receives sends when showing that first of called dont answer is replied identification information, BSC detects CONNECT message, judges called whether replying; And, generate the identification information after upgrading according to the identification information of replying in the identification information of judged result renewal reception.
When Target cell taking place in the BSC switch, BSC sends the target BTS of identification information after switch after upgrading, and is sent to the target TC after the switching by target BTS again.In the practical application, as previously mentioned, BSC can transmit Call_type_flag_bsc, Answer_flag_bsc and DTXd parameter through CHANNEL ACTIVATION message and give target BTS.
When the switching that takes place between the BSC, by the target BS C of MSC after switching send identification information (identification information that sends this moment possibly be different from switch before MSC send to the identification information of BSC; Because exhale the stage rising, reply identification information and corresponding first reply identification information when being initially called dont answer; When switching; Might be called currently reply; Reply accordingly this moment identification information will change into calledly corresponding second reply identification information when having replied), be sent to the target BTS after the switching by target BS C, be sent to the target TC after the switching by target BTS again.In the practical application; MSC can transmit Downlink DTX Flag information through handoff request HANDOVER REQUEST message and give BSS (prior art) when striding the BSC switching; Whether Downlink DTX Flag bit1 sign BSS can use descending DTX function, and bit2 to bit8 is an idle bit, as an example; Can define bit2 again is Call_type_flag_msc, and bit3 is Answer_flag_msc.When Call_type_flag_msc=0, represent caller conversation, when Call_type_flag_msc=1, represent incoming call, when Answer_flag_msc=0, represent called dont answer, when Answer_flag_msc=1 representes calledly to reply.BSS system for having corresponding function can understand those information, and the BSS system that does not have a corresponding function can ignore it, is not affected.
When the switching between the generation MSC; The target MSC of MSC before switching after switching send identification information (identification information that sends this moment possibly be different from switch before MSC send to the identification information of BSC); Be sent to the target BS C after the switching by target MSC; Be sent to the target BTS after the switching by target BS C, be sent to the target TC after the switching by target BTS again.In the practical application; MSC before switching can pass through MAP_PREPARE_HANDOVER (A-HANDOVER REQUEST) and transmit Call_type_flag_msc, Answer_flag_msc and Downlink DTX Flag parameter to target MSC; Target MSC passes to target BS C with it, is passed to target TC at last.
Corresponding processing method after target TC receives DTX identification information, type of call identification information and replys the various combination mode of identification information is identical with above-mentioned TC, does not repeat.
Embodiment 2:
Judge called whether replying by BTS, and according to the identification information of judged result and reception, it is opening or closed condition that notice TC controls descending DTX state.Specifically comprise:
MSC is when call setup; Send identification information to BSC; Identification information comprises: whether allow to use descending DTX function descending DTX identification information, show the type of call identification information of caller conversation or incoming call and show called whether replied reply identification information, BSC transmits identification information and gives BTS;
When using a DTX identification information of descending DTX function when BTS receives permission, show the first type of call identification information of caller conversation and showing that first of called dont answer is replied identification information; Judge called current whether replying; When called dont answer, close indication information to the TC transmission; When called when having replied, send to TC and to open indication information; After TC received and closes indication information, the descending DTX state of control Calling Side was a closed condition; After perhaps TC received and opens indication information, the descending DTX state of control Calling Side was an opening;
When BTS receive a DTX identification information, the first type of call identification information and show called replied second when replying identification information, send to TC and to open indication information; By the descending DTX state of TC control Calling Side is opening;
When BTS receives a DTX identification information and shows the second type of call identification information of incoming call, send the unlatching indication information to TC; The descending DTX state of TC control callee side is an opening;
When BTS receives the 2nd DTX identification information that do not allow to use descending DTX function and the first type of call identification information, close indication information to TC or transmission; The descending DTX state of TC control Calling Side is a closed condition;
When BTS receives the 2nd DTX identification information and the second type of call identification information, close indication information to the TC transmission; The descending DTX state of TC control callee side is a closed condition.
Embodiment 2 compares with embodiment 1; Its main distinction is: among the embodiment 2; BTS can identify (Call_type_flag_bsc), reply sign (Answer_flag_bsc), descending DTX function sign DTXd and called current whether replying according to the type of call that receives, and determines whether to require TC to open or close descending DTX function.
In the practical application, can introduce DTXd ', the C17bit in its corresponding up trau frame, BTS transmits DTXd ' parameter when TC sends trau frame, informs whether use descending DTX function.Concrete situation comprises:
Situation one:
When BTS receives Call_type_flag_bsc=0, Answer_flag_bsc=1, during DTXd=1, the identification information that expression receives is: allow to use descending DTX function, caller call flow and called is replied; Then BTS directly is provided with DTXd '=1 expression and need sends the unlatching indication information to TC, and BTS transmits DTXd '=1 parameter and gives TC through the C17bit in the up trau frame, and requiring TC to control descending DTX state is opening, activates descending DTX function.
Situation two:
When BTS receives Call_type_flag_bsc=0, Answer_flag_bsc=0, during DTXd=1, the identification information that expression receives is: allow to use descending DTX function, caller call flow and called dont answer still; BTS judges called current whether replying, when called current also still during dont answer, DTXd '=0 is set, i.e. expression does not allow to open descending DTX function.BTS transmits DTXd '=0 parameter and gives TC through the C17bit in the up trau frame, and requiring TC to control descending DTX state is closed condition, does not activate descending DTX function.After follow-up BTS detects called party answer, DTXd '=1 is set again, and, transmits DTXd '=1 parameter and give TC through the C17bit in the up trau frame, requiring TC to control descending DTX state is opening, activates descending DTX function.
It is multiple that BTS judges that called current implementation of whether replying has, for example:
Mode one: BTS monitors this up trau frame of conversing, when up trau frame when Idle Speech Frame converts Speech Frame into, judge and calledly reply, otherwise, judge called dont answer;
Mode two: BTS monitors the CONNECT message in this conversation downlink signaling, and when detecting the CONNECT message that BSC issues, judge and calledly reply, otherwise, judge called dont answer.
Situation three:
When BTS receives Call_type_flag_bsc=1, Answer_flag_bsc=1 or 0 is during DTXd=1; The identification information that expression receives is: allow to use descending DTX function, no matter whether the incoming call flow process is then called replying; DTXd '=1 all is set, and BTS transmits DTXd '=1 parameter and gives TC through the C17bit in the up trau frame; Requiring the descending DTX state of TC control callee side is opening, activates the descending DTX function of callee side.
Other situation:
When BTS receives DTXd=0, all_type_flag_bsc=0, expression caller conversation and do not allow to use descending DTX function; DTXd '=0 is set; Through the C17bit in the up trau frame, transmit DTXd '=0 parameter and give TC, requiring the descending DTX state of TC control Calling Side is closed condition;
When BTS receives DTXd=0, all_type_flag_bsc=1, expression incoming call and do not allow to use descending DTX function; DTXd '=0 is set; Through the C17bit in the up trau frame, transmit DTXd '=0 parameter and give TC, requiring the descending DTX state of TC control callee side is closed condition.
Similar with embodiment 1; Among the embodiment 2; In the actual call communication process, no matter caller or called all might take place that switch the sub-district, BSC switches or MSC switching etc. owing to moving; After switching, should make the target TC after switching also can control the open and close of descending DTX state according to current call state.
When comprising in the identification information that MSC that BSC receives sends when showing that first of called dont answer is replied identification information, BSC detects CONNECT message, judges called whether replying; And, generate the identification information after upgrading according to the identification information of replying in the identification information of judged result renewal reception.When the generation Target cell switches in the BSC, by the target BTS after identification information to the switching after the BSC transmission renewal;
When the switching that takes place between the BSC, send identification information by the target BS C of MSC after switching, be sent to the target BTS after the switching by target BS C again;
When the switching that takes place between the MSC, the target MSC of MSC after switching before switching sends identification information, and target MSC is sent to the target BS C after the switching again, and target BS C is resent to the target BTS after the switching;
Corresponding processing method after target BTS receives DTX identification information, type of call identification information and replys the various combination mode of identification information is identical with above-mentioned BTS, does not repeat.
