System information block is divided into MIB (Master Information Block according to its logic function, host system message block), SB (Scheduling Block, Scheduling Block) and three types of SIB (System Information Block, system information block), according to the tree structure tissue.MIB is used for carrying the schedule information of some SIB or SB (maximum 2 SB).MIB also comprises PLMN (Public Land Mobile Network, Public Land Mobile Nerwork) type (being GSM and/or ANSI-41) and the PLMN id information that the sub-district is supported.MIB sends on BCH (Broadcast Channel, broadcast channel belongs to transmission channel) regularly, and delivery time is fixed.Because BCH is mapped in PCCPCH (Primary Common Control Physical Channel, Primary Common Control Physical Channel) on the physical channel, therefore the UE in the sub-district can read the MIB content, and by reading the MIB content, UE can know whether needs to upgrade (perhaps storage) system information.SB is used for carrying the schedule information of other SIB, when the MIB scheduling resource is not enough, adopts SB scheduling SIB.Schedule information can only be present among MIB and the SB.SIB is used to comprise actual system information, always has 18 types SIB, and the schedule information of SIB is by MIB or SB carrying.
Different system information blocks has different features, as repetition period, effective coverage, and effective etc. under what state.The system information elements that the SIB do as one likes matter of a certain type is close is formed.The IE that comprises dynamic parameter (promptly changing frequent system parameters) and static parameter (promptly changing seldom or constant system parameters) is carried by different SIB.The SIB (as SIB1, SIB2 etc.) that comprises static parameter, they are to be worth mark (value tag) as sign.The value mark is the part of schedule information, is included among MIB or the SB.UE compares the value mark of certain type SIB with the last similar offset mark that reads, if value changes, UE will receive this SIB again.Therefore, for the SIB that comprises static parameter, UE just can understand these SIB whether renewal has taken place by monitoring MIB.
The validity that comprises the SIB (as SIB7, SIB14, SIB17 etc.) of dynamic parameter is to adopt the mode of timer expiry to control.Behind the timer expiry, system information becomes invalid, needs to receive again.
Generally, the UE lateral root is according to indicating intactly receiving system information in the schedule information, and still in some cases, under the situation that has the PCCPCH error rate, some SYSTEM INFORMATION message can't normally receive.Receive incomplete problem at system information, it is resident to other sub-district that UE adopts direct gravity treatment usually at present; Perhaps; UE is judging these system informations of disappearance but is not influencing normally residently that then resident this sub-district of UE is under this mode; if UE receives the system information of disappearance continuously; because the current slot signal quality is relatively poor, cause the within a short period of time UE can't all system informations of disposable reception, and UE can take physical resource too much; for this reason; UE can directly abandon receiving the system information of disappearance usually, causes its system information imperfect, can not normally reside in current area.
Summary of the invention
