Description
Technical field
The present invention relates to multimedia broadcast multicast service technology field, be meant the Notification Method and the system of a kind of multimedia broadcast multicast service (MBMS) first choice frequency layer information 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) and be transferred to user terminal (UE).(said hierarchical cell structure among the 3GPP just when the sub-district of a plurality of frequency bands covers same geographic area, Hierarchical Cell Structure, HCS, normally in order to provide more radio channel resource) in certain hot spot region, if these sub-districts provide MBMS service, then these are referred to as the MBMS frequency layer with the different frequency bands that the zone covers.According to the operation strategy, can certain frequency layer be set to the MBMS first choice frequency layer, if the UE in this physical region is moved to the sub-district of this first choice frequency layer, just can save Radio Resource, and better MBMS service is provided.
Specifically which frequency layer is set to the MBMS first choice frequency layer, be by CRNC (ControlRNC, control RNC, be used to control the RNC of UE place cell radio resource) decision, different MBMS services, its corresponding first choice frequency layer may be different (sub-district can provide the transmission service of a plurality of MBMS), and this is also determined by CRNC.
The MBMS first choice frequency layer may change, because CRNC may make a strategic decision and selects the frequency layer of certain sub-district (this decision-making and system of selection are known technology as first-selection according to information such as the resource situation of different frequency layer sub-district, UE number or operation configurations, non-the present invention pays close attention to content, repeats no more).When CRNC determines that certain frequency layer is first choice frequency layer, need be by this first choice frequency layer cell information of the notice of the RRC signaling process between SRNC and UE UE, UE just can go to receive the MBMS service according to this information transfer to the sub-district of first choice frequency like this, and UE also can determine not move (UE migration determining method does not belong to the scope of the invention) certainly.When the RRC of UE connects is to be based upon on the CRNC, and this CRNC is exactly the SRNC (Service RNC, Serving RNC) 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, need notify SRNC with this MBMS first choice frequency layer cell information earlier by the RNSAP signaling of the Iur interface between itself and the SRNC, again by SRNC by the RRC signaling to UE.
DRNC can realize that to SRNC notifying MBMS first choice frequency layer cell information one of them signaling process is direct information transmission (DirectInformation Transfer) flow process by a plurality of RNSAP signaling processes.This signaling process can be used for transmission information between two RNC, and information transmitted comprises the MBMS first choice frequency layer information.
