Embodiment
Basic skills of the present invention is: MGC control MGW goes up processing with the MGW that the user's data business is transferred to the IWF resource apparatus, according to circumstances directly be transparent to the recipient after handling again or go back to the MGW of access again that (when showing at call establishment stage is that data are when professional, can adopt direct transparent transmission mode, also can pass back to the MGW B of access; When call establishment stage is speech business, when the user switches to data service again in communication process, must go back to the MGW of access again).As shown in Figure 2, solid-line curve is represented direct transparent transmission service, user B connects elder generation to fixed network FAX equipment and inserts by MGW B, at this moment, does not have the IWF resource apparatus on the MGW B, after MGC finds that the user is data service, the calling of user B is transferred to MGW A, on MGW A, after the processing of IWF resource apparatus, again data are sent to the GMSC of mobile gateway switching center (or the gateway of data service receiving equipment or switch etc.), and then pass through FAX user.In some cases, the user has set up speech business with other users, at this moment, when both sides switch to data service, data after MGC need handle the IWF of MGW A are transmitted back MGW B again, and then send to gateway exchange GMSC by MGW B, arrive fixed network equipment again, (purpose of doing like this is in order to reduce the influence to external network shown in point curve, because set up speech path with other equipment on voice call stage MGW B right side, when business is switched, its speech path can not discharge, the transmitting data business need be carried at this in system, and therefore the IWF data processed stream through MGW A need rotate back into MGW B again, and this process is sightless to the right side of MGW B.If do not do like this, so just need rebulid the user's who converses with user B carrying from MGW A there, this impact to whole system is bigger).
Be example with protocol controlling procedure H.248 below, describe the specific implementation process of the inventive method.
The specific implementation process of solid-line curve flow process shown in Figure 2 is as follows:
1, MGC finds that according to user's call information the user is a data service calls, determines to need to use the IWF resource apparatus.
2, because the MGW B that the user inserts does not have the IWF resource apparatus, therefore, MGC distributes an IWF passage for it on MGW A.
3, MGC distributes data that rate adaptor (can be used for carrying out the 64Kbps that eats dishes without rice or wine adaptive of data service) transmits the IU interface of RNC (radio network controller) to be fitted to the speed of core net on the MGW B that the user inserts.This step can omit in 2G GSM network A interface, is necessary (adaptive reference agreement is TS 29007) in 3G network.
4, MGC couples together several end points T1, T2, T3, T4 on MGW A and the MGW B, and referring to Fig. 3, method of attachment can be with reference to TS 23205 agreements, and it is the same that the network form after connection is finished switches to MGW B with the user from MGW A.
5, MGC calls out GMSC by signaling, and control MGW A sets up the carrying of T4 to GMSC.
By above several steps, finished data service with user B and be transferred on the IWF resource apparatus on the MGW A and handle.
When the user switches to data service by voice communication, its specific implementation process following (corresponding to the point curve flow process among Fig. 2):
1, MGC increases by two end points T3, T4 earlier on MGW A, and distributes an IWF passage.MGW B sets up (setting up in the speech business stage) to the carrying of GMSC before this.
2, MGC increases end points T3 and T4 on MGW B, and indicates T3 and be connected with T1 is two-way, and T4 is connected with T2 is two-way, and final annexation is revised as shown in Figure 4.Can there be adapter between T3 and the T1 during 2G.
3, MGC connects the T3 of MGW A and the T3 of MGW B, connects the T4 of MGW A and the T4 of MGW B.User's data just can have been handled on the IWF on the MGW A like this, and the data of handling will go back to MGW B.
Certainly, all data services can be walked point curve flow process shown in Figure 2.
Because it is that inevitably therefore, when the user was switched, processing procedure was as follows that the user among the mobile network is switched:
Suppose that the user switches to MGW C from MGW B, then no matter whether MGW C has the IWF resource apparatus of oneself, still use the IWF resource apparatus of MGWA, this point is consistent with agreement TS 29107.
After the user switches to MGW C, in MGWA, increase T5, and the T2 that the T5 of MGW A is connected to MGW C finished switching, its signal transmits schematic diagram as shown in Figure 5, and then the T3 of deletion MGWB connects to the T3 of MGW A, changes the end points T5 of MGW A into two-way connection to the end points T2 connection of MGW C.Form figure as shown in Figure 6.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
