Mark (ECGI) etc.) or Base Station Identification (such as eNB ID) be allocated to UE, as possible reconstruction target cell list or mesh from now on
Mark station list, while the interconnected system information of each cell can also be allocated to UE by RRC dedicated signalings, UE can be into after receiving
Row is preserved to be used in follow-up possible reconstruction process.What wherein current base station can know neighbouring cell according to X2 interface is
UE contexts are simultaneously sent to reconstruction base station by system message.
In this way, when RLF occurs for UE, it is not necessary to cell searching and cell selection are carried out according to tradition RRC connection reconstructions flow,
But the reconstruction target cell list of base station configuration or target BS list directly carry out RRC connection reconstructions directly before,
The request of RRC connection reconstructions is sent directly on the SRB0 of Target cell, since target BS have received UE contextual informations,
Therefore it can greatly improve reconstruction success rate to avoid the reconstruction failure caused by lacking UE contexts, so save cell
Search and the time of read system message, shorten the time of reconstruction, also save the electricity of UE.
Fig. 3 shows RRC connection reconstruction flow diagrams in the NBIoT of one embodiment of the invention.It is as shown in figure 3, our
Method includes step S1 to S6.
In step S1, when UE and current base station are in RRC connection status, current base station carries out RRC connection reconfigurations to UE
Put.
In this step, current base station sends RRC connection reconfigurations to UE and puts message, and reconstruction Target cell can be carried in the message
List or target BS list.More than one cell or base station can be included by rebuilding in target cell list or target BS list,
These cells or base station can be represented with cell ID or Base Station Identification.Cell ID for example can be：Physical Cell Identifier
(PCI)+frequency point information, or network cell global identity ECGI (E-UTRAN Cell Global Identifier) information
Deng the mark of base station is such as can be eNB ID, but the present invention is not limited thereto.
In embodiments of the present invention, the cell in reconstruction Target cell (or base station) list or base station can be according to priority
To arrange.The priority can based on measurement report of the UE real-time reports to cell (such as Reference Signal Received Power (RSRP),
Reference Signal Received Quality (RSRQ) etc.) determine, but the present invention is not limited thereto.

In message in addition to carrying and rebuilding Target cell (or base station) list, the system letter of each cell in list can also be carried
Breath.Alternatively, system information can also be allocated to UE by other RRC dedicated signalings.
UE can be preserved after receiving reconstruction Target cell (or base station) list and system information, so as to follow-up possible
Used in reconstruction process.
In step S2, current base station sends UE contextual informations to base station is rebuild.
After RRC connection reconfigurations are sent to UE and put message, current base station can also be sent out UE contexts according to X2 interface
Give the reconstruction target BS for rebuilding each cell in Target cell (or base station) list.In an alternative embodiment of the invention, currently
Base station can be only to rebuild highest priority in Target cell/station list one or base station transmission above and below the UE of preceding several cells
Literary information.
In step S3, when RLF occurs for UE, UE selects the small of highest priority from reconstruction Target cell/station list
Area/base station, for directly being rebuild.Then in step S4, UE the request of RRC connection reconstructions is initiated to the reconstruction base station of selection.
I.e. in embodiments of the present invention, it is not necessary to carry out cell searching and cell according to traditional RRC connection reconstructions flow
Selection, but the reconstruction target cell list of base station configuration directly carries out RRC connection reconstructions directly before, can directly select
The request of RRC connection reconstructions is sent on the SRB0 for the Target cell selected.
In step S5, rebuild RRC connection reconstruction request of the base station based on UE and carry out RRC connection reconstructions.
UE contextual informations have been have received due to rebuilding base station, can be to avoid caused by lacking UE contexts
Reconstruction failure, greatly improves reconstruction success rate.After the completion of connection reconstruction, in step S6, UE returns to RRC connections weight to base station is rebuild
Build completion message.
Above-mentioned flow based on the embodiment of the present invention, not only saves the time of cell searching and read system message,
So as to shorten the time of reconstruction, the electricity of UE is also saved.
In practical applications, due to UE be often it is mobile, it is therefore preferred that current base station can at regular intervals into
Row is once rebuild Target cell/station list and is reconfigured.Carrying out rebuilding the time interval that reconfigures of target cell list can
To be fixed or unfixed, such as the time interval reconfigured can be selected according to the translational speed of UE
Length, it is slow-footed to reconfigure that the cycle is relatively long, translational speed it is fast to reconfigure the cycle relatively short.Or current base station can be
When up channel measurement finds that the link-quality of UE is gradually deteriorated, if link-quality is less than certain threshold value, (UE occurs RLF's at this time
Probability greatly increases) when triggering rebuild cell list configuration.
Compared to the renewal for rebuilding Target cell/station list, the cycle that cell system information generally requires renewal compares
Long (for example several hours are even longer), the frequency of renewal can be lower.Therefore, RRC dedicated signalings can be used to update small fauna
System information.Alternatively, can also be notified with rebuilding target cell list synchronized update cell system information to UE.
, can be by if UE and the cell reconstruction failure of the highest priority of selection in addition, in embodiments of the present invention
Next cell/base station is selected to be rebuild from reconstruction Target cell/station list according to priority orders.
Based on the embodiment of the present invention, Target cell or station list, and corresponding small fauna are rebuild in current base station configuration
System information, notifies to UE.In addition UE contexts are sent to reconstruction target BS by base station.In this way, UE is no longer carried out after RLF occurs
