Description
Technical field
The present invention relates to multimedia broadcast multicast service (MBMS) technical field, be meant MBMS channel type Notification Method and system between a kind of radio network controller (RNC) especially.
Background technology
From 3GPP R6,3GPP has defined multimedia broadcast multicast service (MBMS, MultimediaBroadcast Multicast Service), is used for providing the broadcast or multicast business to the mobile subscriber of communication system.In 3G wireless access network UTRAN, the MBMS data from core net will be carried on the descending radio bearer (RB, Radio Bearer) to be transmitted.The employed logic channel of the radio bearer of this MBMS correspondence can be Dedicated Traffic Channel (DTCH) or MBMS point-to-multipoint service channel (MTCH, MBMS Point-to-Multipoint Traffic Channel).If DTCH, DTCH will be mapped on dedicated channel (DCH), forward access channel (FACH), the DSCH Downlink Shared Channel of time-division (DSCH), the high speed descending sharing channel transmission channels such as (HS-DSCH) so; If MTCH, then MTCH is mapped on the FACH transmission channel.Concrete employing DTCH still is that MTCH comes the MBMS transmission data, be by CRNC (Control RNC, control RNC, be used to control the RNC of UE place cell radio resource) (concrete non-the present invention of decision-making technique pays close attention to content, does not give unnecessary details herein) of making a strategic decision according to the UE number and the current cell radio resource state of this MBMS of registration service in the current area.If adopt the DTCH channel, the data of this MBMS service are point-to-point transmission mode (PTP Mode) so, have only the terminal (UE) of certain appointment just can receive by the data of DTCH Channel Transmission.If adopt the MTCH channel, be so point to multicast communication pattern (PTM Mode), the data by the MTCH Channel Transmission can be received by the UE that all of this sub-district or other sub-districts add this multicast service.
From as can be known above-mentioned, the data of being served by CRNC decision MBMS are by point-to-point mode or point to multipoint mode transmission.And CRNC can be according to the situation of change of current wireless resource status, register the information such as situation of change of the UE number of this service, changes transmission mode (can change to from point to points and a little arrive multiple spot, vice versa).Be originally by the point-to-point mode transmission such as certain MBMS service, when situation changes (such as there being a plurality of UE to register up), the CRNC decision is transformed into the point to multipoint mode transmission, to save Radio Resource.In the time of CRNC decision conversion transmission mode, need conversion by this transmission mode of the notice UE of RRC (Radio Resource control) signaling process between SRNC (Service RNC, Serving RNC) and the UE.When the RRC of UE connects is to be based upon on the CRNC, and this CRNC is the SRNC of this UE, otherwise this CRNC is the DRNC (Drift RNC is used for UE and sets up the RRC connection by the Radio Resource of DRNC control with SRNC) of this UE.
When CRNC is DRNC, the information of conversion MBMS transmission mode need be passed through its RNSAP with the Iur interface between the SRNC (RNS application protocol) signaling earlier, notify SRNC, (may follow foundation or release or other operation of MBMS channel by the RRC signaling to UE by SRNC again, non-the present invention pays close attention to content, does not give unnecessary details herein).
The conversion of certain MBMS transmission mode of DRNC notice SRNC is (because the different transmission mode correspondence different channel types, so also can be described as the conversion of channel type), can realize by a plurality of RNSAP signaling processes, one of them signaling process is called direct information transfer process (DirectInformation Transfer), as shown in Figure 1, this flow process is used in transmission information between two RNC, comprising the channel type information (different channels type correspondence different MBMS transmission modes) of MBMS.
Show the RNSAP direct information message transfer in current 3GPP standard, stipulated (specifically can referring to the 9.1.69 trifle of TS25.423 v6.8.0) as following table 1:

Table 3
Here, relation between each information element in the above-mentioned message is described: the information element that has "＞" number is the 2nd a grade of information element, is a lowest-rank element (being similar to structure in the data structure and subordinate's field thereof) of its higher level's information element (not with this number).In like manner, the information element that has "＞＞" is the 3rd level element, belongs to the lowest-rank element of its higher level with "＞" number information element, by that analogy to the information element that has a plurality of "＞".
TMGI in the table 3 is used for a MBMS carrying service of unique identification (MBMS bearerservice), the data that the 3GPP network provides MBMS carrying service to be used for the MBMS transmission service.In the Access Network of 3GPP, provide MBMS carrying service by radio bearer and corresponding correlated channels thereof.As mentioned above, a MBMS carrying service can be used point-to-point mode (PTP) in Access Network, just transmit with the dedicated channel type, also can use point to multipoint mode (PTM), just transmits with the multicast channel type.
By above-mentioned table 1, table 2 and table 3 as can be seen, a direct information transmits the information (same TMGI has different channel types in different sub-districts) that (DirectInformation Transfer) message can only comprise a TMGI and channel type thereof.Therefore, when a RNC has the channel type informational needs of a plurality of TMGI to notify another RNC, just need initiate repeatedly direct information transfer process, need a plurality of direct information message transfers of transmission.
This will cause the system handles complexity to improve problems such as transmission network bandwidth waste.And, when the RNC that receives this information need carry out subsequent treatment, because each information receives respectively one by one, therefore also one by one the TMGI in each message of individual processing (SRNC can not wait for that receiving all direct information message transfers initiates with the RRC process between the UE again, because it can't know the follow-up direct information message transfer that whether also has), the TMGI in a plurality of message can not be merged and carry out subsequent treatment (even if the channel type of these TMGI changes simultaneously).This further will cause the complexity of subsequent treatment to increase again, reduce the entire system performance.
For example SRNC receives the MBMS channel type information that DRNC sends, and finds that channel type has become, and needs notice UE and orders it according to the conversion between PTP and the PTM, carries out foundation or release or other operations of PTP channel.In the prior art, if DRNC has the channel type of a plurality of TMGI to change, need to initiate a plurality of direct information transfer process and notify SRNC one by one respectively, SRNC whenever receives this message, will initiate the RRC process and give UE, thereby the RRC process that causes can initiating between a plurality of SRNC and the UE changes can handle a plurality of TMGI channel types.Its processing procedure can be referring to shown in Figure 2.
By above-mentioned analysis and shown in Figure 2, when DRNC need handle a plurality of TMGI channel types simultaneously and changes, a plurality of with the direct information transmission course between the SRNC (each process is handled a TMGI) with initiating, it is a plurality of with RRC signaling process between the UE and relevant subsequent treatment that this can cause that again SRNC initiates.And possibility that a plurality of TMGI channel types change is arranged simultaneously among the DRNC than higher, because a UE can customize a plurality of MBMS services generally speaking, because a such UE switches under the DRNC, will cause that the DRNC decision changes the transport-type of a plurality of TMGI, perhaps CRNC determines the transmission mode of a plurality of TMGI is converted to PTM or is transferred to PTP (these conditions may be because change or the S-CCPCH/FACH resource distribution increase or the minimizing etc. of the threshold value of OMC configuration PTP number of users) by PTM by PTP simultaneously under certain conditions.RRC signaling process repeatedly will directly cause DRNC, and the processing complexity of SRNC and UE all increases, and the signaling process between a plurality of network elements increases, radio channel resource waste, the performance of reduction whole system.
