During UE access MBMS special carrier network, if this UE does not support special carrier MBMS business, this UE need exit this MBMS special carrier network, Fig. 1 is that embodiment of the present invention UE carries out exiting schematic flow sheet in the resident process of network, as shown in Figure 1, first UE needs to synchronize and access with this network, if synchronously access successfully, by primary synchronization channel (Primary Synchronisation Channel; Hereinafter to be referred as: PSC)/auxiliary synchronization channel (Secondary Synchronisation Channel; Hereinafter to be referred as: whether SSC) obtain the sign of community, by cell ID, obtain reference signal, this reference signal is a PN sequence, obtains the initial value of PN sequence according to the sign of community, to identify current area, be a work community of LTE; If synchronous access failure, exits current area, again initiate the synchronous access procedure of other community, this is the first exit point.
Obtain after cell ID and reference signal, after UE demodulation PBCH, obtain Master Information Block (Master Information Block; Hereinafter to be referred as: MIB) information, if now can not correctly obtain mib information, UE exits access procedure, re-starts synchronous access, this is the second exit point.
After success obtains mib information, UE also needs further to obtain system information block (System information block; Hereinafter to be referred as SIB) information, only have after successfully obtaining SIB1/SIB2 information and just can proceed the resident subsequent process in community, realize the successful access of network; If obtain SIB1/SIB2 information, do not exit access procedure, this is the 3rd exit point.
According to three of above-mentioned flow process exit points, for can, by above-mentioned three escape mechanisms, avoiding the UE of different system to reside in incompatible network when network insertion with the incompatible UE of current network.Various embodiments of the present invention exit while providing a solution to make second exit point of UE in network insertion flow process, avoid not supporting that the subscriber equipment of special carrier MBMS business resides in MBMS special carrier network.
Fig. 2 is embodiment of the present invention method for sending information flow chart, and as shown in Figure 2, the method comprises:
Step 100, application specific multicast cyclic redundancy check (CRC) mask, in Physical Broadcast Channel information, for the cyclic redundancy check information of verification Master Information Block information, carry out scrambling processing;
If mobile terminal will successfully be linked in wireless network, it must successfully get the mib information that this wireless network issues, that is to say, if wireless network allows mobile terminal to be linked in present networks, its mib information issuing should be moved terminal and obtain.If mobile terminal can not correctly obtain mib information, according to the regulation of existing RAN agreement, the mobile terminal access process that will exit network.UE access MBMS special carrier network for fear of not supporting special carrier MBMS business, can make not support that the UE of special carrier MBMS business can not obtain correct mib information.In the embodiment of the present invention, base station by the cyclic redundancy check information of PBCH (hereinafter to be referred as: CRC) use a kind of special-purpose multicast cyclic redundancy check (CRC) mask to carry out scrambling, make this UE that does not support special carrier MBMS business cannot correctly solve the mib information of PBCH carrying, thereby make this UE can not obtain mib information, exit thus the proprietary carrier network of MBMS, avoid this UE to reside in this network.
Be specially, the information sending by PBCH is Physical Broadcast Channel information, as shown in table 1, Physical Broadcast Channel information specifically comprises mib information and CRC information, wherein mib information is 24 information bits, 16 cyclic redundancy bits of CRC information, the CRC information of 16 obtains according to 24 mib informations, for mib information is carried out to verification.Network side, for aerial information is carried to UE, can be applied mask CRC information is carried out to scrambling processing, and mask is corresponding with aerial information, specifically as shown in table 2, and three kinds of different masks represent respectively three kinds of antenna configurations.According to the number of actual transmission antenna, choose corresponding mask, then apply mask CRC information is carried out to XOR processing, make CRC carry aerial information.UE adopts the method for blind check, decodes respectively, and with mask corresponding to respective antenna number, CRC is separated to XOR according to the send mode of an antenna, two antennas and four antennas, then judges that whether its mib information is correct, with this, knows number of transmission antennas.Certainly the UE corresponding relation of pre-stored mask and antenna configuration, do not support to store equally clean culture as shown in table 2/mask information in composite mode on the UE of special carrier MBMS business, when not supporting the UE access MBMS special carrier network of special carrier MBMS business, also can obtain correct mib information, thereby cannot avoid this UE resident at MBMS special carrier network.On the basis of embodiment of the present invention mask under existing clean culture/mixed mode, increase a special-purpose multicast cyclic redundancy check (CRC) mask under the multicast pattern that is applicable to special carrier, apply this special use multicast cyclic redundancy check (CRC) mask CRC information is carried out to scrambling processing, then again the CRC information of processing through scrambling is sent out by under PBCH together with mib information.And this special use multicast cyclic redundancy check (CRC) mask will prenotice the UE that supports special carrier MBMS business, make to support that the UE of special carrier MBMS business can be correctly decoded CRC.For the UE that does not support special carrier MBMS business, can not obtain special-purpose multicast cyclic redundancy check (CRC) mask, therefore can not be correctly decoded CRC, can not correctly obtain mib information, therefore impel its access process that exits network.
The special-purpose multicast cyclic redundancy check (CRC) mask relating in the present embodiment, as long as being different from three kinds of different CRC masks that three kinds of antenna configurations of existing protocol regulation are corresponding is (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0), (1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1) and (0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1), for example special-purpose multicast cyclic redundancy check (CRC) mask can use (1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0), in order to guarantee can to select (1 in systematic function the present embodiment, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0) as special-purpose multicast cyclic redundancy check (CRC) mask, table 3 is the Hamming distance between special-purpose multicast cyclic redundancy check (CRC) mask and existing mask, as can be seen from Table 3, this special-purpose multicast CRC mask newly increasing does not change minimum Hamming distance, therefore can not reduce systematic function.

Base station is for fear of not supporting the UE of special carrier MBMS business to receive mistakenly mib information, base station can also be further according to network side and the UE that supports special carrier MBMS business predetermined, corresponding to the SIB structure of multicast pattern, be updated in the system information block message sending in data channel, the SIB information of renewal is crossed in the concurrent warp let-off.For supporting the UE of special carrier MBMS business owing to knowing in advance the SIB structure of multicast pattern, therefore can according to network side and subscriber equipment predetermined, corresponding to the system information block structure of multicast pattern, the SIB information that reception base station sends by data channel; And for not supporting the UE of special carrier MBMS business, even if this UE has received mib information mistakenly, but because this UE can not obtain SIB information, access process equally must exit network.
Below introduce the flow process that embodiment of the present invention UE obtains MIB, this flow process specifically comprises the steps:
First UE searches for synchronizing channel PSC/SSC, is synchronized to MBMS special carrier network;
By synchronizing channel, obtain sign and the reference signal of community;
According to demodulation reference signal PBCH;
Because the generative process of mib information is as follows: the mib information by 24bit is a 0, a 1, a 2, a 3..., a 23obtaining 16 CRC information is p 0, p 1, p 2, p 3..., p 15, CRC bit is counted mask x as shown in Table 4 according to transmit antenna ant, 0, x ant, 1..., x ant, 15carry out scrambling, by following formula, generate final bit sequence c 0, c 1, c 2, c 3..., c 39.
c k＝a k，for k＝0，1，2，...，A-1；
c k＝(p k-A+x ant，k-A)mod2，for k＝for k＝A，A+1，A+2，...，A+15(A＝24)。
Table four
The antenna number of base station parameter PBCH CRC mask < x ant，0，x ant，1，...，x ant，15>
1 <0，0，0，0，0，0，0，0，0，0，0，0，0，0，0，0>
2 <1，1，1，1，1，1，1，1，1，1，1，1，1，1，1，1>
3 <0，1，0，1，0，1，0，1，0，1，0，1，0，1，0，1>
Multicast <1，0，1，0，1，0，1，0，1，0，1，0，1，0，1，0>
Therefore UE will obtain mib information, just need to apply CRC mask the CRC processing through mask XOR is separated to XOR processing.Do not support the UE of special carrier MBMS business according to the antenna opening number of table four 1,2 and 4, to verify the correctness of mib information, because what now MBMS special carrier network was used is special-purpose multicast CRC mask, therefore do not support the UE of special carrier MBMS business that check errors will occur, thereby can not correctly receive mib information, access process then exits network.For the UE that can access MBMS special carrier network, can use the special-purpose multicast CRC mask of the PBCH of multicast to verify the correctness of mib information, thereby obtain mib information, then continue executive resident in the subsequent operation of MBMS special carrier network.
