In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The present invention realizes fax intercommunication between mobile network and the fixed network by a number.Fig. 1 shows and realizes network configuration of the present invention, wherein:
IWF (Interworking Function, IWF) module mainly is responsible for the intercommunication of mobile network and fixed network data service, be divided into TAF (Terminal Adapter Function, terminal adapter function) and two functional modules of FA (Fax Adaptor, facsimile adapter unit).The TAF module mainly be responsible for and portable terminal between adaptive, by RLP (Radio Link Protocol, radio link protocol), L2RCOP (Layer 2 Relay Character Oriented Protocol, the directed agreement of layer 2 relay feature) sets up the Radio Link between IWF and the terminal, detailed content is referring to the description of 3GPP TS 27001/27002/27003 agreement, and the present invention repeats no more.The FA module is faxed to be correlated with the fixed network facsimile machine on the one hand and is consulted (FaxNegotiation), finish the fax adaption function by the FA module of fax adapting protocol (FA Protocol) and end side on the one hand in addition, see the description of 3GPP TS 23146 agreements for details, the present invention repeats no more.Communicate by letter by signaling v.24 between the FA module of end side and the TAF module.RNS is responsible for the network of wireless side and sets up; MGW (Media GateWay, media gateway) mainly is responsible for various carrying media streams, as IP (Internet Protocol, Internet protocol), TDM (Time Division Multiplex, time division multiplexing) or the conversion between the ATM (Asynchronous Transfer Mode, asynchronous transfer mode); MGC (Media Gateway Controller, Media Gateway Controller) is responsible for the control of media gateway; MSC (Mobile Switching Centre, mobile switching centre) is responsible for calling out relevant signaling process.
Bearer network between MSC1 and the GMSC2 (Gateway Mobile Switching Center, gateway MSC), between MGC and the GMSC2 may exist also and may not exist.
In the following embodiments, two lateral terminals all are to set up voice call earlier, switch to FAX mode then.The flow process of setting up speech business belongs to prior art, and the present invention no longer describes.Between portable terminal and the facsimile machine (Fax) and the interaction flow between portable terminal and the IWF see also the description of 3GPP TS 23146 agreements, the present invention quotes at this, repeats no more.
In embodiment one, fixed network side detects behind the facsimile signal sound by the signaling gateway exchange, is adapted to by gateway exchange and initiates fax by signaling method to mobile side behind the mobile signaling protocol and switch.Below to be carried as IP carrying, signaling is that SIP (Session Initiation Protocol, SIP) agreement describes, as shown in Figure 2, details are as follows:
(1) fixed network side MGC notice MGW3 detects the fixation side facsimile signal sound, and fixed terminal and portable terminal are set up voice call (among the figure 1～3).
(2) fixed terminal is changed to FAX mode with facsimile machine, and facsimile machine sends CNG (Calling Tone, calling tone) signal tone (among the figure 4,5) to MGW3.
(3) MGW3 detects the CNG signal tone, gives MGC (among the figure 6,7) with this incident by information reporting H.248.
(4) MGC is fax by SIP signaling message indicating services type, pass to next processing node by sip message, when message arrives gateway exchange MSC (GMSC2), the fax type Indication message of fixed network side is adapted for the bearer modification signalling of mobile side by GMSC2, afterwards with bearer modification signalling by the signaling transmission, finally be delivered to the MSC1 of end office (EO) and go up (among the figure 8,9).
(5) after MSC1 receives the bearing modification message that last node sends over, if MSC server (MSC1) is supported this kind ability, the corresponding MGW of indication revises Codec (encoding and decoding), increases the IWF resource, activates IWF function, (the Echo Cancel of the EC when turning off voice call on the one hand, echo cancellation), carrying also will be changed the JitterBuffer parameter simultaneously if core net is IP; Initiate on the one hand the bearing modification (among the figure 11～12) of wireless access side in addition; If the MSC server is not supported this modification ability, then this voice call switches to fax failure;
Middle all relevant bearer are carried out corresponding modify, at UMTS (Universal MobileTelecommunications System, universal mobile telecommunications system) after bearing modification finishes in the network, IU interface UP (User Plane, user's face) pattern will change to transparent mode by original support mode, and Nb interface UP carries out the initialization (not shown) possibly again
(6) IWF consults with the mobile terminal side modulation on one side, and an other end and fixed network side are carried out modulation and consulted, and carries out facsimile transmission (among the figure 13～15) after consulting successfully.
If any operation failure, then this fax handoff procedure is failed in the above-mentioned flow process, and switching flow finishes.
In embodiment two, fixed network side is delivered to gateway exchange with facsimile signal sound by in-band method, and gateway exchange is adapted to mobile signaling protocol after detecting the fax incident, notifies the switching of mobile side initiating speech conversation to fax by signaling method then.
Fixed network side carries three kinds of modes when being delivered to gateway exchange by in-band method: full TDM carrying, full IP bearing and TDM and IP mix carrying.
As shown in Figure 3, when fixed network is carried for TDM entirely to the carrying of gateway exchange MGW2, the CNG signal of facsimile machine can be directly delivered on the MGW2, detect this incident (among the figure 1～5) by MGW2, by gateway exchange MSC (GMSC2) voice call is switched to the fax incident then and be adapted to the relevant signaling message of APM (application transport mechanism), send signaling message to MSC1 (among the figure 6～8), MSC1 initiates the modification of mobile side carrying, carries out facsimile transmission (among the figure 9～13) after mobile side bearing modification is finished.Mobile side bearing modification process is identical with embodiment one, repeats no more.
When fixed network when the bearing mode of gateway exchange is full IP bearing, after fixed network side detects facsimile signal sound, it by the mode in the band, as is utilized transmission such as RFC2833, V152, finally be delivered to gateway exchange, detect by gateway exchange.After being that with the difference of TDM carrying the carrying of fixed network side detects facsimile signal sound, bearing modification is finished in segmentation, promptly revises the intra-office carrying earlier, revises the interoffice carrying by signaling method then, and detailed process can repeat no more with reference to figure 4.
As shown in Figure 4, when fixed network is that TDM carrying and IP carry when existing alternately to gateway exchange, mobile effluent journey is identical with embodiment one, repeats no more.Below only the fixed network side flow process is described, wherein the A reference point is that TDM carrying, B reference point are the TDM carrying:
(1) fixed terminal and portable terminal are set up voice call (among the figure 1～7).
(2) after the MGW3 of fixed network side end office (EO) detects the CNG signal, give MGC by information reporting H.248.The Codec of MGC by the change of message H.248 intra-office bearer network is for G.711, the CNG signal passes through in-band method, as RFC2833, V152 etc., by the T3a endpoint transfers among the figure to the T4b end points, on the T4a end points CNG signal is recovered, follow-up CNG signal can be gone up (among the figure 8～16) by the inlet MGW that TDM is delivered to next tandem exchange.Need to prove that what provide among the figure is that bearer types that B is ordered is the TDM carrying, if the bearer types that B is ordered is the IP carrying, then MGC can pass to MGCi by sip message with the fax indication, changes Codec between T4a and Tjb, and the CNG signal can utilize in-band method to the next node transmission equally.
(3) the inlet MGWj of next tandem exchange detects the CNG signal, same gives corresponding MGCi by information reporting H.248.The Codec of MGCi by message modification intra-office bearer network H.248 be for G.711, the operation in the operation of follow-up CNG signal same (2) identical (among the figure 17～24).
(4) the CNG signal is delivered on the gateway exchange MGW2, after MGW2 detects the CNG signal, by information reporting H.248 on the GMSC2, after GMSC2 learns that business changes to facsimile service by voice call, this incident is adapted for the bearer modification signalling message of mobile side, notifies mobile side to carry out corresponding modify (among the figure 24～28) by signaling method.Mobile effluent journey is identical with embodiment one, carries out facsimile transmission (among the figure 29) after mobile side bearing modification is finished.
The above-mentioned A reference point that only provided is that TDM carrying, B reference point are the realization flow of TDM carrying, and the carrying of other type similarly repeats no more.
In embodiment three, fixed network directly is delivered to mobile side with facsimile signal sound by in-band method, by mobile side detect and initiating speech conversation to the switching of FAX mode.When facsimile signal sound was delivered to mobile side by in-band method, the carrying of mobile side was divided into full TDM carrying, packet bearer, TDM carrying and the mutual three kinds of modes of packet bearer, below described respectively.
As shown in Figure 5, when mobile side is carried as full TDM carrying, after fixed terminal and portable terminal are set up voice call, voice call is switched to FAX mode (among the figure 1～4), the MGW1 that the CNG signal is transparent to end office (EO) goes up (among the figure 5), after the MGW1 of end office (EO) detects and reports voice call to switch to the fax incident, by BICC (Bearer Independent Call Control, with the calling of bearer independent control) signaling message notice GMSC2 revises Codec in the bearer network (among the figure 6～8), corresponding MSC server (MSC1) is initiated Codec and is revised, increase the IWF resource, activate IWF function etc. and handle (among the figure 9～11), identical among modification process and the embodiment one, repeat no more, in the UMTS network internal, UP may need to consult again (among the figure 12～13), carries out facsimile transmission (among the figure 14) after mobile side bearing modification is finished.
When mobile side core net is carried as packet bearer (being carried as example) with IP, as shown in Figure 6, can pass through in-band method, as utilize RFC2833, V152 etc. to transmit the CNG signal of fax, describe with RFC2833.After fixed terminal and portable terminal are set up voice call (among the figure 1～5), MSC server (GMSC2) by RFC2833 with the MGWi of CNG signalisation correspondence (among the figure 6～9), report MSCi by MGWi, by MSCi come by the BICC signaling to process carrying and insert side and initiate Codec and revise, comprise EC when closing voice call, change JitterBuffer parameter etc. (among the figure 10～20).Modification is carried out piecemeal, revise Codec until MSC1 and finish (among the figure 21～34), MSC1 increases the IWF resource, activate the IWF function, change RAB and carry out modulation negotiation etc. (among the figure 35～39), because UP is with reference to variation may take place, need carry out the initialization (among the figure 40) of UP again, carry out facsimile transmission (among the figure 41) after mobile side bearing modification is finished.
When mobile core network was carried as TDM and packet bearer and exists alternately, the fixed network core net was that TDM and the IP realization of carrying when mutual is similar among implementation procedure and the embodiment two.
After mobile side MGW detects facsimile signal sound, facsimile signal sound is reported corresponding MSC.The encoding and decoding that MSC revises the intra-office bearer network are for G.711, and MGW is delivered to the MGW of next mobile tandem exchange with facsimile signal sound, after the mobile MGW of tandem exchange detects facsimile signal sound, reports corresponding M SC, and the encoding and decoding of MSC modification intra-office bearer network are for G.711.Repeat this process until facsimile signal sound being delivered to the MGW of end office (EO);
After the MGW of end office (EO) detects facsimile signal sound, be reported to the MSC of end office (EO), the MSC of end office (EO) switches the fax incident with voice and is adapted for bearer modification signalling message, notifies mobile side to carry out bearing modification by signaling method.Utilize BICC message between the MSC server this moment, rather than ISUP (ISDN User Part, ISDNYong Hubufen) message.Codec need carry out initialization again to UP after revising and finishing., be not described in detail with aforementioned identical for the processing of MGW of end office (EO) and Access Network.
Need to prove that in the present invention, when the fixed network lateral terminal switched to the fax attitude, the bearing modification of mobile side also can be initiated by signaling method by portable terminal.
