The first, behind the virtual subdistrict of UE access to 4G, when more than the capacity of 4G virtual base station, needs UE weight
It is directed to 2G, the principle that 4G is redirected to 2G is as follows:
It is interrogated in SIB7 (SystemInformationBlockType7, system information block type 7) message arrangement 2G cell
Breath.For meeting all UE of condition, after UE initiates access request, L3 issues RRC_RELEASE information, will redirect cell
Information (Redirected Carrier Info indicates the frequency point redirected and scrambling code information) brings UE, and UE can be realized from 4G
It is redirected to 2G.And according to UE access to the principle of the virtual subdistrict 2G, it is once linked into the virtual subdistrict 2G in the 2G mobile phone of net, entirely
Standard virtual base station can maintain UE and 2G multiband multi-standard virtual base station link not interrupt.
It second, behind the virtual subdistrict of UE access to 3G, when capacity is more than the cell of 3G, needs to redirect UE
The principle for being redirected to 2G to 2G, 3G is as follows: it is similar with the principle that 4G is redirected to 2G, after UE initiates access request, under RNC
Reject (refusal) or release (release) information is sent out, indicates the frequency point of 2G, cell information will be redirected and bring UE
Realize that UE is redirected to 2G from 3G.And according to UE access to the principle of the virtual subdistrict 2G, void is once linked into the 2G mobile phone of net
