Embodiment
On the path of core net, except that MGW, also there is miscellaneous equipment, for example language strengthens equipment EC, in embodiments of the present invention these equipment is referred to as IPE equipment, and IPE equipment adopts TDM to insert usually.
The embodiment of the invention detects the particular service sign by MGW or IPE in TDM side (receiving the code stream that transmits in the TDM mode), perhaps detect predefined PT (bearer types) value in IP side (receiving the code stream that transmits in the IP mode), finish the identification of particular service, current bearing mode is switched to described particular service can transmission manner, the direct transparent transmission mode of clearmode mode or Bypass mode or encode/decode-free for example, solve with this and to carry out T office in core net and transform, perhaps after the transformation of A mouth IPization, the problem that some particular service can't successful execution.
Described clearmode mode is about to the TDM code stream and handles in non-packed byte mode, and the packing of dividing into groups transmits;
Described Bypass mode, i.e. bypass mode refers to that EC equipment in speech channel or language enhancing equipment etc. do not process the TDM code stream, and input signal is directly sent to output, is called direct-passing mode again.
Can realize transmission by above-mentioned three kinds of modes (clearmode mode or Bypass mode), avoid core net to carry out T office and transform that perhaps the compression coding and decoding that traditional IP adopts after the transformation of A mouth IPization can't transmit the problem of described particular service to the TDM code stream.
Carry out T office with the specific embodiment explanation in core net below and transform, perhaps the scheme of after the transformation of A mouth IPization particular service being handled (processing procedure with MGW is that example describes).
Embodiment one: suppose that core-network side carried out the VOIP of T office and transformed (referring to Fig. 2), this transformation is invisible to BSC, and the processing of BSC side is constant.
After MGW sets up the audio call passage, start ISLP synchronous head and frame head information simultaneously and detect, for the continuous 0X7e that guarantees professional correctness, can set to detect the regulation number as the judgement benchmark, after for example being consecutively detected 6 above 0x7e, can adjudicating and detect particular service.After detecting described particular service, MGW can adopt following dual mode to finish the bearing mode switching, thereby realizes the processing to particular service:
Mode one: MGW adopts the mode that automaticallyes switch: the bearing mode of encoding and decoding speech is switched to the clearmode mode, the opposite end gateway is behind the message that receives the Clearmode mode, also automatically switch to the clearmode mode, thereby finish the foundation of the described particular service passage of transmission, guarantee the described particular service transmission success of on TDM, carrying.This mode can rely on the fixed configurations on the MGW to finish, and perhaps MGC issues parameter request MGW and finishes automatically;
Switching mode under mode two: the MGC control: MGW reports MGC with professional testing result, after detecting described particular service, carrying out bearing mode by MGC control MGW switches, the bearing mode of encoding and decoding speech is switched to the clearmode mode, simultaneously also notify the opposite end gateway to finish corresponding change action, thereby finish the foundation of clearmode passage, guarantee the described particular service transmission success of on TDM, carrying.
Present embodiment is by detecting ISLP synchronous head and frame head information in real time in the TDM side, thereby particular service is discerned, after identifying particular service, automatically switch to the mode that to transmit described particular service or realize described switching by MGW by MGC control, solve the T office improved core net of VOIP and can't handle the particular service problem, and its method that detects described particular service accurately, in time, does not need to increase new control and signaling interface, and its handover scheme is easy, be easy to realize.
Embodiment two: suppose that core-network side carried out A mouth IP and transformed, adopt the IP mode to connect (referring to Fig. 3) between the described MGW;
After MGW sets up voice channel, if portable terminal is initiated particular service and is handled indication, after BSC receives described particular service indication, the bearer types of current speech passage is switched to the bearer types of particular service, BSC can transmit according to predefined mode, it is adaptive to carry out ISLP to described particular service, also can not carry out ISLP adaptive (if during the non-TrFO of follow-up MGW, realizing that by MGW ISLP's is adaptive).If it is adaptive to carry out ISLP on the BSC, be about to voice flow and switch to the ISLP mode, described particular service information is transmitted by the ISLP mode, owing on IP, transmit, so need to adopt packing manner, therefore the adapted data message can be transmitted according to the clearmode mode, and be designated as particular service bearer types 1, i.e. PT1; If it is adaptive not carry out ISLP, then adopt particular service bearer types 2, promptly adopt the PT2 mode to transmit, concrete mode is as follows:
Mode one: it is adaptive that the BSC side is carried out ISLP:
After MGW sets up voice channel, portable terminal is initiated particular service, the BSC side directly adopts predefined PT to encapsulate the particular service message, and this PT is designated as particular service PT1, and MGW detects the message PT type of IP side, after MGW detects the message of this PT1 type, because MGW has been TrFO, promptly described MGW both sides are with a kind of bearing mode, and present embodiment is the IP bearing mode, the described particular service of the direct transparent transmission of then described MGW does not carry out encoding and decoding.
Mode two: BSC does not adopt ISLP adaptive the particular service message:
After MGW sets up voice channel, portable terminal is initiated particular service, the BSC side directly adopts predefined PT to encapsulate the particular service message, this PT is designated as particular service PT2, MGW detects the message PT type of IP side, after MGW detects the message of this PT2 type, if MGW has been TrFO, then direct transparent transmission does not carry out encoding and decoding.
After present embodiment has realized that A mouth IP transforms, BSC encapsulates according to predefined bearer types and transmits described particular service, MGW detects the bearer types of IP side, because MGW has been TrFO under the scene of present embodiment, so directly the described particular service of transparent transmission has been realized the processing to described particular service.
Embodiment three: suppose that under the situation of A mouth IP transformation, the interface between MGW and MGW adopts TDM mode, the perhaps mode of non-TrFO (referring to Fig. 4);
The processing procedure of BSC can be identical with embodiment two, repeats no more herein.
After MGW set up voice channel, MGW detected the message PT type of IP side, and when detecting particular service, it is adaptive to judge whether described particular service has carried out ISLP, can adopt following dual mode to handle according to different judged results:
Mode one, do not carry out ISLP adaptive (being that described BSC adopts PT2 to transmit) when the PT indication particular service that detects the BSC side, if MGW controls switching automatically, then MGW with this particular service message adopt ISLP encapsulate adaptive after, on TDM, transmit.If MGC control is switched, then by MGW notice MGC, MGC issues and switches indication, and MGW finishes the adaptive conversion of special message to ISLP according to described switching indication.
Mode two, carried out ISLP adaptive (being that described BSC adopts PT1 to transmit) when the PT indication particular service that detects the BSC side, if MGW controls switching automatically, after then MGW directly adopts the Clearmode mode to handle this particular service message, on TDM, transmit.If MGC control is then notified MGC by MGW, MGC issues and switches indication, and MGW transmits on TDM after adopting the clearmode mode to handle according to described switching indication.
Present embodiment by detecting the PT type, carries out corresponding conversion process according to the difference of described PT type in core-network side, has realized that the A mouth carries out IP and transforms and adopt at the interface between MGW and the MGW under the situation of TDM mode processing to particular service.
