Abstract
The embodiment of the invention discloses a method for judging a radio link failure, which comprises the following steps that: an MAC (Media Access Control) layer of user equipment reports a random access problem indication to an RRC (Radio Resource Control) layer of the user equipment based on carriers or a carrier set of the user equipment; the RRC layer judges whether the carriers of the user equipment have a random access problem of the MAC layer according to the reporting form and the reporting content of the random access problem indication; and when the RRC layer judges that all carriers of the user equipment have the random access problem of the MAC layer, the RRC layer judges that the user equipment has the radio link failure. The technical scheme of the embodiment has the advantage of solving the problem of judging the radio link failure in the carrier aggregation because the radio link failure is judged aiming at UE instead of single carrier.
Description
Technical field
The present invention relates to the 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.Simultaneously, LTE-A system requirements and LTE system are compatible well, the maximum bandwidth 20MHz of LTE system.Based on improve peak rate, with the LTE system compatible with make full use of the needs of frequency resource, the LTE-A system has 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 the CA technology condense together, and are the UE service simultaneously, rather than have only the pattern of a cover carrier wave before in LTE system and the wireless communication system.Base station (as eNB) is to unified management of many covers member carrier and scheduling, and the conversion of different members intercarrier is a resource allocation problem in a base station.Member carrier can be continuous or discrete, for the 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 the 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 the part of carrier aggregation, at FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) in the system, the 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 the part of carrier aggregation; The expansion carrier wave can not independently exist, a part as carrier aggregation.
When UE (User Equipment, subscriber equipment) is under the carrier aggregation operating state, one or more specific carriers that can define in its polymerization carrier wave are the main carrier of UE.The main carrier of UE can be by network configuration, for example, the carrier wave of UE Serving cell is defined as the main carrier of UE, UE can only monitor the system information on the main carrier, carrying out the sub-district based on main carrier switches, perhaps only monitor the PDCCH (Physical Downlink Control Channel, physical downlink control channel) of main carrier etc.In general, the main carrier of UE has only one.In the carrier aggregation transmission course, the main carrier of UE can remain unchanged, and also can be reconfigured by network.
In the LTE system, UE judges whether to detect Radio Link Failure (RadioLink Failure) based on following condition: the T310 timer expiry; Receive the indication of access problem at random that the MAC layer reports, work as T300, T301, T304 is when the 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 with physical layer synchronization " in-sync ", and concrete rule is: receive N310 " out-of-sync " indication and the T300 that sends from bottom continuously as UE, T301, T304 when the T311 timer is invalid, then starts timer T310; When the T310 run duration, receive N311 " in-sync " indication from bottom continuously, then UE stops timer T310.
In addition, T300 is used for RRC (Radio Resource Control, Radio Resource control) and connects and set up process, and T301 and T311 are used for RRC connection reconstruction process, and T304 is used for handoff procedure.When RRC connects the process of setting up, RRC connection reconstruction process or handoff procedure generation, rrc layer will be ignored the indication of access problem at random that the MAC layer reports, and can not adjudicate UE Radio Link Failure has taken place.
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
Radio Link Failure decision method in the LTE system all is based on single carrier, promptly carries out at 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 all inoperable situations.

10. device as claimed in claim 7 is characterized in that, when described MAC layer function module reports the indication of access problem at random based on carrier set,
Described rrc layer functional module is used for specifically judging that the access problem at random of MAC layer has all taken place all member carriers of described carrier set.
11. device as claimed in claim 7 is characterized in that,
Described rrc layer functional module, also be used to judge the carrier set generation Radio Link Failure of described subscriber equipment, the information of described carrier set generation Radio Link Failure is passed through dedicated signaling informing network side apparatus, make described network equipment carry out deexcitation or reconfiguration operation described carrier set.
12. as each described device in the claim 8 to 11, it is characterized in that the member carrier in the described carrier set has the similar characteristic of channel, the described characteristic of channel comprises continuous carrier or has identical timing advance TA.
