Description
Technical field
The link monitoring that the present invention relates to the communications field reports technology, particularly relates to a kind of auxiliary cell radio link failure and monitors the method, the Apparatus and system that report.
Background technology
At present, Long Term Evolution strengthens (LTE-A, LongTermEvolutionAdvanced) peak rate of system is relative to Long Term Evolution (LTE, LongTermEvolution) system is greatly improved, such as, require that downlink transfer speed reaches 1Gbps, uplink speed reaches 500Mbps; Meanwhile, require that lte-a system and LTE system have good compatibility.Therefore, compatible and make full use of the needs of frequency spectrum resource based on improving peak rate, with LTE system, lte-a system introduces carrier aggregation (CA, CarrierAggregation) technology.
CA technology refers to that network side is the multiple community of terminal configuration (CELL), terminal can work on multiple CELL simultaneously, a CELL comprises a pair up (UL, UpLink)/descending (DL, DownLink) member carrier (CC, ComponentCarrier) or only have DLCC, this point is different from LTE system and wireless communication system before the pattern only had a terminal, be only configured with a set of carrier wave.In the lte-a system using CA technology, each CC can be continuous on frequency spectrum, and also can be discrete, the bandwidth between each CC can be identical or different, and in order to keep compatible with LTE system, the maximum bandwidth of each CC is restricted to 20MHz; At present, the CELL number being generally a terminal configuration is 5 to the maximum.
In addition, LTE-A also classifies to the CELL through carrier aggregation, comprises main plot (PCELL, PrimaryCELL) and auxiliary community (SCELL, SecondaryCELL), wherein:
In CELL for multiple polymerizations of terminal equipment configuration, a CELL is only had to be defined as PCELL; In CELL for multiple polymerizations of terminal equipment configuration, other CELL except PCELL is called SCELL.
PCELL is selected by network side and by RRC signal deployment to terminal, the PCELL of different terminals can be different, specify in LTER10 version, the difference of PCELL and SCELL is that PCELL and several functions are bound, and the major function of PCELL binding is as follows:
PCELL is only had to be configured with physical layer control channel (PUCCH, PhysicalUplinkControlChannel), for transmission of channel quality information (CQI, ChannelQualityIndicator), hybrid automatic repeat-request (HARQ, HybridAutomaticRepeatRequest) feedback information (ACK, and specific schedule request (D-SR, DedicatedSchedulingRequest) Acknowledgement);
The descending of PCELL can as the UL timing reference carrier wave (ULTimingReference) of Stochastic accessing; PCELL can as the path loss of PCELL and other SCELL with reference to (PLR, PathLossReference);
Only have on PCELL and can carry out Stochastic accessing (RACH, RandomAccessChannel); Only have on PCELL and can configure semi-continuous scheduling (SPS, Semi-PersistingScheduling) resource; Only have when Radio Link Failure (RLF, RadioLinkFailure) PCELL occurs, just think that RLF occurs terminal.
In addition, in the mobile communication system in future, by introducing minimum road test (MDT, MinimumDriveTest) technology, by the measurement result of the terminal equipment report network environment in network, the artificial participation of the network planning and Operation and Maintenance can be reduced, by network according to the statistic optimize parameters au tomatically reported, reduce construction and the operation cost of network.
Usually, MDT obtains the relevant parameter required for the network optimization mainly through the measurement report of mobile terminal reporting, to reach the object reducing carrier network optimization and maintenance cost.Compared with traditional drive test, MDT has energy-saving and emission-reduction, reduces drive test expense, shortens the advantages such as optimization cycle, can bring higher user satisfaction; Further, the region-wide metrical information that traditional drive test cannot carry out can be collected, as narrow road, forest, private site etc.The main application scenarios of MDT is the optimizations of coverage optimization, capacity optimization, mobile management optimization, service quality (QoS, QualityofService) parameter optimization and common signal channel parameter configuration.
It is the part of MDT technology that RLF reports, and for reporting the wireless signal measurement result of current Serving cell and surrounding adjacent area to network side when terminal judges is in RLF, carries out coverage optimization to contribute to network.Current, if terminal configuration has multicarrier, only when RLF occurs PCELL, just can record and report relevant information to network.
Along with the development of LTE technology, amount of bandwidth will become further important, and current techniques does not report for SCELL generation RLF, also brings inconvenience for subsequent network is optimized SCELL.
