Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to a kind of method and apparatus of adjudicating Radio Link Failure.
Background technology
The peak rate of LTE-A (Long Term Evolution Advanced, senior Long Term Evolution) system has huge raising than LTE (Long Term Evolution, Long Term Evolution) system, requires to reach descending 1Gbps, up 500Mbps.Meanwhile, LTE-A system requirements and LTE system are compatible well, LTE system maximum bandwidth 20MHz.Based on improving peak rate, with LTE system compatible with make full use of the needs of frequency resource, LTE-A system has been introduced CA (Carrier Aggregation, carrier aggregation) technology.As shown in Figure 1, be the carrier format schematic diagram of LTE system; As shown in Figure 2, be the carrier aggregation form schematic diagram of LTE-A system.
A plurality of member carriers (upstream or downstream) in CA technology condense together, and are UE service simultaneously, rather than in LTE system and wireless communication system before, only have the pattern of a set of carrier wave.Base station (as eNB) is to the unified management of many covers member carrier and scheduling, and in a base station, the conversion of different members intercarrier is resource allocation problem.Member carrier can be continuous or discrete, for LTE system compatible, the maximum bandwidth of each member carrier is 20MHz, the bandwidth between each member carrier can be identical or different.The type of the member carrier in CA technology comprises backward compatibility carrier wave (backwards compatiblecarrier), non-backward compatible carrier waves (Non-backwards compatible carrier) and expansion carrier wave (Extension carrier) etc., wherein, backward compatibility carrier wave and LTE system compatible, can independently exist, also can be used as a part for carrier aggregation, at FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) in system, backward compatibility carrier wave always occurs in pairs, be DL (Down Link, down link) carrier wave and UL (Up Link, up link) carrier wave always matches, non-backward compatible carrier waves not with the LTE system compatible of earlier version, can independently exist, also can be used as a part for carrier aggregation, expansion carrier wave can not independently exist, a part as carrier aggregation.
When UE (User Equipment, subscriber equipment) is under carrier aggregation operating state, can define the main carrier that the one or more specific carriers in its polymerization carrier wave are UE.The main carrier of UE can be by network configuration, for example, the carrier wave of UE Serving cell is defined as to the main carrier of UE, UE can only monitor the system information on main carrier, based on main carrier, carry out community switching, or only monitor the PDCCH (Physical Downlink Control Channel, physical downlink control channel) of main carrier etc.In general, the main carrier of UE only has one.In carrier aggregation transmitting procedure, the main carrier of UE can remain unchanged, and also can be reconfigured by network.
In LTE system, UE judges whether to detect Radio Link Failure (RadioLink Failure) based on following condition: T310 timer expiry; Receive the random access problems indication that MAC layer reports, work as T300, T301, T304, when T311 timer is invalid; Receive the indication of the arrival maximum retransmission that rlc layer reports.
Wherein, T310 is relevant with step-out " out-of-sync " indication to physical layer synchronization " in-sync ", and specific rules is: when UE receives N310 " out-of-sync " indication and the T300 sending from bottom continuously, T301, T304, when T311 timer is invalid, starts timer T310; When T310 run duration, from bottom, receive N311 " in-sync " indication continuously, UE stops timer T310.
In addition, T300 connects process of establishing for RRC (Radio Resource Control, Radio Resource is controlled), and T301 and T311 are for RRC connection reconstruction process, and T304 is for handoff procedure.When RRC connects process of establishing, RRC connection reconstruction process or handoff procedure and occurs, rrc layer, by the random access problems indication of ignoring MAC layer and reporting, can not adjudicated UE Radio Link Failure has occurred.
Inventor is in realizing process of the present invention, and at least there are the following problems to find prior art:
Radio Link Failure decision method in LTE system, all based on single carrier, carries out for a work carrier wave, and when being applied to carrier aggregation mechanism, in the time of can causing a carrier wave wireless link-quality variation, other all carrier waves are inoperable situation all.

8. device as claimed in claim 6, is characterized in that, when described MAC layer function module reports random access problems indication based on carrier set,
Described rrc layer functional module, specifically for judging that the random access problems of MAC layer has all occurred all member carriers in described carrier set.
9. device as claimed in claim 6, is characterized in that,
Described rrc layer functional module, also for judging the carrier set generation Radio Link Failure of described subscriber equipment, the information exchange of described carrier set generation Radio Link Failure is crossed to dedicated signaling informing network side apparatus, make described network equipment carry out deexcitation or reconfiguration operation to described carrier set.
10. the device as described in any one in claim 6 to 9, is characterized in that, the member carrier in described carrier set has the similar characteristic of channel, and the described characteristic of channel comprises continuous carrier or has identical timing advance TA.
