Description
The application is to submit Patent Office of the People's Republic of China, Application No. 201210519716.3, invention name on December 06th, 2012
The referred to as divisional application of the Chinese patent application of " system information sends, acquisition methods and equipment ", entire contents are by quoting
It is incorporated in the present application.
Technical field
The present invention relates to wireless communication field, more particularly to a kind of transmission of system information, acquisition methods and equipment.
Background technology
As the fast-developing and user of user terminal (User Equipment, UE) is to data service rate and capacity
Demand constantly increase, monolayer overlay network is not for traditional macro base station (Macro evolved NodeB, Macro eNB)
This situation can be met.Therefore, 3GPP introduces the mode of layering networking solving the problem：By in hot spot region, family
The little overlay environment such as indoor environment, working environment lays some lower powered base stations (including forms such as Femto/Pico/ relayings),
Obtain the effect of cell splitting so that operator can provide the user more high data rate, more inexpensive business.Layering group
In the case of net, macrocell (Macro Cell) provides basis and covers, and cell (Small Cell) provides extra system capacity.
System information in Long Term Evolution (Long Term Evolution, LTE) system is divided into Master Information Block
(MasterInformationBlock, MIB) and multiple system information blocks (SystemInformationBlocks, SIB), bag
Include SIB1 to SIB15).Table 1 below describes the major function of each system information：
Table 1
In order to ensure concordance that UE and network are understood to system information, the concept in system information modification cycle is introduced,
System information contents within the modification cycle can not change, and system information modification can only be from next system information modification week
The start time of phase starts.I.e. when UE learns system information is changed after, monitor in next start time in modification cycle and new be
System information.LTE system supports the advice method of two kinds of system information changes：
First, network side notifies the UE changing system informations of Idle state and connected state using beep-page message, and UE is in the next one
The modification cycle begins listening for new system information；
Second, network side carrying system information change label (systemInfoValueTag) letter in the SIB1 for sending
Breath, if the UE system information change labels for reading and the difference for storing before, then it represents that system information occurs change, needs weight
It is new to read；The effect duration of UE storing system informations is 3 hours, if exceeding the time, UE needs to re-read system information.
For ETWS information (being included in SIB10-SIB11) in system information and CMAS information (being included in SIB12)
Change, it is allowed to UE does not adopt read access time point specified in system information changing process.There are reception ETWS or CMAS information energy
The UE of power has detected whether ETWS or CMAS Notification of Changes information by beep-page message, when monitoring Notification of Changes information immediately
Read ETWS and the particular content in the system information block of CMAS places.
The UE of connected state and Idle state is only read out and is updated to the system information which needs, and unwanted for which
System information can not be read out and update.
As network side does not send public information in (non-standalone) cell that dependent works (as system is believed
Breath), the resource such that it is able to the public information for saving is taken is used for the data transfer of UE.But for not sending system
The cell of information, the UE of Idle state cannot be resident, so non-standalone cells need not support Idle state
UE is worked thereon, and only needs to support that the UE of connected state is worked thereon.Therefore, non-standalone cells and need not
By be provided only to the UE of Idle state using system information be supplied to the UE of connected state, these are supplied to what the UE of Idle state was used
System information includes：SIB3 to SIB8, SIB14.But for the other systems information that the UE of connected state can be supplied to use, still
So it is provided to connected state UE to use.
The UE of connected state works in non-standalone cells mainly following three kinds of modes：
Mode 1：Carrier aggregation mode.In existing carrier aggregation mode, non-standalone cells can conduct
Secondary cell (Scell) is allocated to the UE of connected state, so as to UE can utilize the resource of non-standalone cells to be operated.
And as existing carrier aggregation mode only supports main plot (PCell) and SCell in the scene of identical eNB, therefore which
The field of (standalone) cell for the autonomous working for also there are same eNB controls is only used under non-standalone MPS process
Scape.
Mode 2：Connected state switching mode.The UE of the connected state worked in standalone cells can be by being switched into
The mode for entering non-standalone cells is realized working in non-standalone cells.
Mode 3：Carry separate mode.In this mode, a part of the UE of connected state carries (Radio Bearer, RB)
It is split into from Macro Cell on Small Cell, so as to the UE for realizing connected state can be non-standalone's
Work on Small Cell.The operative scenario of which such as Fig. 1 is described.In this scenario, different from existing carrier aggregation side
Formula, Macro Cell and Small Cell may belong to different eNB.The wireless heterogeneous networks (RRC) for safeguarding UE of UE
The chain of command signaling bear (Signalling Radio Bearer, SRB) of the transmitting-receiving of the control signaling of connection is main in Macro
On the Macro Cell of eNB controls, by Macro eNB and Mobility Management Entity (Mobility Management
Entity, MME) connection, the user face data of the data transmit-receive for UE of UE can be carried (Data Radio
Bearer, DRB) all or part of it is separated on the Small Cell of home base stations (Local eNB).While Macro eNB
There can also be the connection with gateway (Serving Gateway, S-GW) with Local eNB, to realize the number of respective DRB
According to transmission.UE may have SRB on Local eNB (part RRC control signaling can be sent by Small Cell), it is also possible to
Without SRB (RRC control signaling is sent by all passing through Macro Cell).
The formula that UE calculates pager meeting (Paging Occasion, PO), the PO of UE are defined in current 36.304 agreement
According to system (time division duplex (TDD) or FDD (FDD)), the paging density nB value of network settings, acquiescence paging cycle
DefaultPagingCycle length, UE identify the different and different of (ID).
In simple terms, it is directed to FDD system, the position such as table 2 below that the PO of UE is likely to occur in a wireless frame in, for
In TDD system, the position such as table 3 below that the PO of UE is likely to occur in a wireless frame in：
FDD:
| Ns | PO when i_s=0 | PO when i_s=1 | PO when i_s=2 | PO when i_s=3 |
| 1 | 9 | N/A | N/A | N/A |
| 2 | 4 | 9 | N/A | N/A |
| 4 | 0 | 4 | 5 | 9 |
Table 2
| Ns | PO when i_s=0 | PO when i_s=1 | PO when i_s=2 | PO when i_s=3 |
| 1 | 0 | N/A | N/A | N/A |
| 2 | 0 | 5 | N/A | N/A |
| 4 | 0 | 1 | 5 | 6 |
Table 3
To sum up, for the UE of the connected state worked in the non-standalone cells of not broadcast system information, the company
The UE for connecing state cannot obtain the system information of its needs from non-standalone cells, require consideration for how to allow these UE to obtain
