Description
Technical field
The present invention relates to field of wireless communication, a kind of network side is indication MB SFN (Multicast Broadcast Single Frequency Network in measuring control messages, multicast broadcast single frequency network)/method of IMB (Integrated Mobile Broadcast, complete mobile broadcast) carrier wave.
Background technology
Along with popularizing of large-screen multi-functional mobile phone, the application of mobile data services more and more widely, demand to mobile communication no longer is satisfied with phone, message and surfing Internet with cell phone browse service, in order to effectively utilize mobile network resource, 3GPP (third generation partner program) has proposed multimedia broadcasting and multicast service (MBMS, Multimedia Broadcast Multicast Service), in the mobile network, provide a data source to send the point-to-multipoint service of data to a plurality of users, the realization Internet resources are shared, improve utilization rate of network resource, the especially Bao Gui interface resource of eating dishes without rice or wine.The MBMS of 3GPP definition can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multicast and the broadcasting of high-speed multimedia business, and multiple rich video, audio frequency and multimedia service are provided.The MBMS business comprises: multicast service (Multicast Service) and broadcasting service (Broadcast Service).
In 3GPP Rel7 (version 7), introduce MBSFN (Multicast Broadcast Single Frequency Network, multicast broadcast single frequency network) technology.The MBSFN technology is to unite the one group of co-frequency cell that covers the geographic area, uses identical main scrambler and channel code, the same MBMS business of synchronized transmission.This complete descending FDD (Frequency Division Duplex, frequency diversity is multiplexing) carrier wave or TDD (Time Division Duplex, time diversity is multiplexing) carrier wave that has only carried the MBMS business is exactly the MBSFN carrier wave.
In 3GPP Rel8 (version 8), introduce IMB (Integrated Mobile Broadcast, complete mobile broadcast) technology, be in the WCDMA network on the 3.84McpsTDD carrier wave, adopt complete descending time slot, and this complete descending TDD carrier wave only carries the MBMS business, and this complete descending 3.84MbpsTDD carrier wave that has only carried the MBMS business is exactly the IMB carrier wave.
According to present 3GPP standard, terminal can only reside in the sub-district of FDD layer (FDD carrier wave), and necessarily there is the covering of FDD in the area that has MBSFN/IMB to cover so.And MBSFN/IMB has only the downlink broadcast channel, network to terminal the behavior on MBSFN/IMB know nothing, whether network side can not receive professional by control UE from the MBSFN/IMB layer.The UE that can receive the MBSFN/IMB carrier wave is the terminal of a double-receiver, and a receiver receives the MBSFN/IMB carrier wave, and a receiver receives the FDD descending carrier.
The covering of MBSFN/IMB is limited, especially networking initial stage, in order to be implemented in the whole network operation MBMS business, when the FDD sub-district has with the MBSFN/IMB carrier wave that covers, then UE (subscriber equipment, User equipment) can receive general service and receiving the MBMS business simultaneously on the IMB carrier wave on the FDD carrier wave, and if do not have the MBSFN/IMB carrier wave to cover, then UE needs to set up special-purpose the connection on the FDD carrier wave, and UE receives the MBMS business on this special use connects.
Consider above factor, the solution thought that we propose is if UE knows the covering quality of MBSFN/IMB, just can own selection is from the MBSFN/IMB reception or to the MBMS business of FDD frequency layer request clean culture, that is:
1. the user has selected a MBMS business, and when the MBSFN/IMB covering quality was bad, the terminal active request was set up clean culture with FDD and is connected; When the IMB covering quality was good, the MB SFN/IMB receiver of terminal received the MBMS business from MB SFN/IMB cluster;
When the terminal that receives the MBMS business from MBSFN/IMB when IMB covers the edge and moves, clean culture with regard to active request and FDD when terminal detects of poor quality that MBSFN/IMB covers is connected, clean culture connect set up professional receive successfully after terminal stop the reception of MBSFN/IMB;
3. when the terminal that receives the MBMS business by clean culture from the FDD sub-district during to good regional mobile of MBSFN/IMB covering quality, terminal detect the MBSFN/IMB quality when good the MBSFN/IMB receiver set up and be connected with the broadcasting of MBSFN/IMB sub-district, after connection foundation business received successfully, the terminal request deletion was connected with the clean culture of FDD sub-district.
The thing that will do of network is how MBSFN/IMB carrier wave metrical information to be notified to UE so.These information can be placed in the broadcast message of FDD sub-district.
In addition, according to present 3GPP standard, the frequency point information of MBSFN/IMB is notified in the SIB11 with the FDD sub-district that covers.
The problem that exists is at present, when the UE under being in special-purpose connection mode switches to target FDD sub-district from a FDD sub-district, UE may not can read the system broadcast message of FDD Target cell, UE does not know on the target FDD sub-district whether the MBSFN/IMB carrier wave is arranged so, and MBSFN/IMB metrical information and can't judge the MBSFN/IMB carrier-quality.When UE will read MBMS when professional, UE need search for the MBSFN/IMB carrier wave of 3GPP regulation one by one, not only makes the terminal power consumption, and the user may need to stand one period stand-by period and just can see business.
