Referred to as RRC) connection establishes/re-establishing/and switches, and a serving cell provides Non-Access Stratum (NonAccess Stratum, letter
Referred to as NAS) mobile message (for example, tracking area instruction (Tracking Area Indicator, referred to as TAI)), Yi Ji
RRC connection re-establishments/switching, main plot provide safety input.The descending carrier that main plot uses is referred to as descending principal component carrier wave,
Up-link carrier is referred to as up principal component carrier wave.Secondary cell is referred to as descending from component carrier, up-link carrier being referred to as using descending carrier
It is up from component carrier.
For each secondary cell, the use of UE ascending resource and the use of downlink resource configure constantly, configuration
Down-link auxiliary component carrier wave (Downlink Secondary Component Carrier, referred to as DL SCC) quantity
More than or equal to up-link auxiliary component carrier wave (Uplink Secondary Component Carrier, referred to as UL SCC)
Quantity, and no Scell can be only configured to ascending resource.
For UE angle, each ascending resource only belongs to a serving cell (i.e. Pcell or Scell).Service

Step S502, the measurement parameter that user equipment (UE) issues according to main plot (Pcell) base station, to Radio Link matter
The radio link quality for measuring the time reference cell of the non-primary cells declined carries out restorative measurement.
Step S504, in the case of the not up to default wireless link recovery condition of result of measurement, user equipment is to master
Cell base station sends the radio link quality report of the time reference cell of non-primary cells, wherein, radio link quality report
In carry TA groups where the time reference cell of Radio Link Failure secondary cell (Scell) radio link quality ginseng
Number.
By the embodiment of the present invention, the measurement parameter issued according to main plot base station, radio link quality is declined non-
The radio link quality of the time reference cell of main plot carries out restorative measurement, in the not up to default radio chains of the result of measurement
In the case of road recovery condition, to the TA groups where the time reference cell of main plot base station transmission carrying Radio Link Failure
The radio link quality report of the radio link quality parameter of secondary cell, realizes the non-primary cells to sending Radio Link Failure
Time reference cell radio link quality measurement.
After the sending module 104 of user equipment 1 sends radio link quality report, main plot base station 2 receives wirelessly
Link Quality Reports, new secondary cell is chosen according to radio link quality report and joined as the time of the TA groups of Radio Link Failure
Examine cell, and the wireless spread-spectrum technology for sending to user equipment 1 mark for the time reference cell for carrying selection is reconfigured and disappeared
Breath.The receiving module 106 of user equipment 1 receives the wireless spread-spectrum technology reconfiguration message that main plot base station 2 is sent, triggering configuration
The time reference cell configuration of the TA groups of Radio Link Failure is choosing according to wireless spread-spectrum technology reconfiguration message by module 108
Cell indicated by the mark of the time reference cell taken.
Before the wireless spread-spectrum technology reconfiguration message that receiving module 106 receives that main plot base station 2 is sent, user equipment
1 can continue to measure the radio link quality of the time reference cell of current radio link failure, in the result of measurement
In the case of reaching default wireless link recovery condition, notice main plot base station 2, which is suspended to user equipment 1, sends Radio Link control
Reconfiguration message processed.In a preferred embodiment of the embodiment of the present invention, the sending module 104 of user equipment 1 can be to
Main plot base station 2 sends Radio Link Failure and recovers instruction message, and instruction main plot base station 2, which is suspended to user equipment 1, sends nothing
Wired link controls reconfiguration message.
According to embodiment of the present invention, a kind of reconfiguration device of time reference cell is additionally provided, can be, but not limited to
In the main plot base station 2 that the above embodiment of the present invention provides, the time of the non-primary cells of radio link quality decline is embodied as
The TA group reconfiguration times reference cell at the place of reference cell.
Fig. 6 is the structured flowchart of the reconfiguration device of time reference cell according to embodiments of the present invention, as shown in fig. 6,
The device can include：Receiving module 202, choose module 204 and sending module 206.Wherein, receiving module 202, for receiving
The radio link quality report of the time reference cell for the non-primary cells that user equipment is sent, takes in radio link quality report
Radio link quality parameter with the secondary cell (Scell) in Timing Advance (TA) group, above-mentioned TA groups are current radio chains
The TA groups that road quality is not up to where the time reference cell of the non-primary cells of default recovery condition.Module 204 is chosen, with reception
