For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
The present invention considers in the 3GPP agreement, binding logo (Binding ID) cell is used for a transmission bearer of unique identification Iub interface, and when user data passes through the AAL2 transmission of ATM, this binding ID connects corresponding one by one with AAL2, be that binding ID is used to discern different AAL2 connections, when setting up the transmission bearer of MBMS, binding ID is essential parameter, in the prior art, all need to transmit an identical MBMS when professional for three sub-districts shown in Figure 1, set up the situation of three MBMS transmission bearers on Iub interface, the AAL2 that each MBMS transmission bearer is set up connects corresponding binding ID.Utilize this binding ID to be connected characteristic one to one with AAL2 among the present invention, with binding ID as the same Iub transmission bearer shared of sign different districts.Further, when user data connects transmission by IP, can also set up the one-to-one relationship that this binding ID is connected with IP, connect to discern different IP, then when transmission bearer be IP when connecting, the same Iub transmission bearer that binding ID can be shared as the sign different districts equally.Specific implementation is referring to method flow shown in Figure 3.
Fig. 3 is the exemplary process diagram of the transmission bearing method of MBMS business in the embodiment of the invention.This flow process comprises the steps:
Wherein, the professional indication of this MBMS is used to indicate a specific MBMS business, because a NoedeB may support a plurality of MBMS business, which MBMS business therefore needs the current MBMS business of indication is.During specific implementation, can increase the professional indication information element of MBMS in Common Transport Channel Setup Request message, the name of cell can be decided as the case may be, as may be defined as " Broadcast Reference ".
In addition, this Common transport channel is set up other relevant information that also comprises the MBMS business in the request, for example, because the professional corresponding forward access channel (FACH) of MBMS, so this Common transport channel is set up MBMS transmitting channel informations such as also can comprising transmission channel ID in the request.
Wherein, the mode of generation binding ID can have multiple.Can carry out respective settings according to actual needs, for example, Fig. 4 shows a kind of structural representation of binding ID.As shown in Figure 4, for the binding ID of 32 bits, can in its preceding 8 bits, fill NodeB ID, fill Cell ID in 8 bits subsequently, the transmission channel ID that mentions in the filling step 301 in 8 bits subsequently again, last 8 bits can be filled out of Memory as required; Perhaps, the fill order of above-mentioned each information also can combination in any or also can be chosen one or more arbitrarily and fill, and shared separately bit number also can be adjusted as required.Certainly, binding ID also can have other information combination to fill, for example, and the port numbers of the User Datagram Protoco (UDP) (UDP) in the IP transmission, the arbitrary carrier identification in the multicarrier etc.Then these information constitute the value of a binding ID jointly, and this value is used for corresponding one by one with the transmission bearer of setting up afterwards, and this binding ID itself also can be used for representing multiple customizing messages simultaneously.
Certainly, binding ID also can be a value that generates at random, is used for correspondingly one by one with the transmission bearer of foundation afterwards, and itself can be not used in the expression out of Memory this binding ID.
In addition, the NodeB transmitting channel information of setting up the MBMS in the request message according to Common transport channel in the step 301 is set up S-CCPCH Secondary Common Control Physical Channel (SCCPCH) channel of physical layer in the current area carrier wave.
In addition, the NodeB transmitting channel information of setting up the MBMS in the request message according to Common transport channel in the step 301 is set up the SCCPCH channel of physical layer in the current area carrier wave.
Wherein, transmission bearer can be that ATM AAL2 connects, and also can be that IP connects.Wherein, AAL2 connects by virtual path number (VPI), Virtual Channel number (VCI) and channel logo parameters such as (CID) definite.IP connects by IP address and tunnel endpoint identifier (TEID) definite.
In the above-mentioned flow process, NodeB can connect the corresponding relation of (VPI/VCI/CID) or IP layer connection (IP address+tunnel endpoint identifier (TEID)) according to binding ID, the professional indication of MBMS and ATM layer AAL2, identification is that a kind of MBMS business, and binding ID and which MBMS is professional and there is corresponding relation in which sub-district, therefore can finish the MBMS sharing operation in NodeB.
Further, for similar binding ID shown in Figure 4, because the specified byte of binding ID also has special implication, as shown in Figure 4, then RNC receives after the binding ID, which NodeB RNC can know this binding ID from according to the NodeB ID in the binding ID, know that according to sub-district ID this sub-district is which sub-district under the NodeB, and then knows it is the professional corresponding FACH ID of which MBMS etc. according to transmission channel ID.
