Description
Technical field
The present invention relates to wireless communication field, more particularly to a kind of Radio Link Failure reporting and processing method and sets
It is standby.
Background technology
In following GSM, it is desirable to minimize drive test (Minimum Drive Test, MDT) by introducing
Technology, by the measurement result of terminal (UE) report network environment in network, reduces the artificial of the network planning and Operation and Maintenance
Participate in, by network according to the statistic Automatic Optimal parameter reported, reduce construction and the operation cost of network.
MDT mainly obtains the relevant parameter required for the network optimization by the measurement report of mobile terminal reporting, with up to
To the optimization of reduction carrier network and the purpose of 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, and can be collected into traditional drive test to enter
Capable region-wide metrical information (such as narrow road, forest, private site).MDT main application scenarios are coverage optimization, capacity
Optimization, mobile management optimization, qos parameter optimization and the optimization of common signal channel parameter configuration.Long Term Evolution (Long Term
Evolution, LTE) system and UMTS (Universal Mobile Telecommunications
System, UMTS) system all supports MDT technologies.Current LTE system and UMTS system all pass through idle message as shown in Figure 1
Flow obtains UE MDT measurement result.
Radio Link Failure (Radio Link Failure, RLF) report be MDT technologies a part, for working as terminal
The wireless signal measurement result of current serving cell and surrounding adjacent area is reported when judging to be in RLF to network side, to contribute to
Network carries out coverage optimization.Currently, only LTE system supports RLF to report, and UMTS system does not support RLF to report.
In LTE system, there are following three kinds of reasons to cause RLF：
First, UE physical layer report n times step-out primitive (out-of-sync), and UE wireless heterogeneous networks (RRC) layer is opened
Dynamic timer, if receiving the n times synchronization primitives (in-sync) that physical layer is reported before timer expiry, cancels timer, no
Then think to there occurs RLF in timer expiry.
Second, rlc layer maximum retransmission is reached；
3rd, medium education (MAC) layer random access failure.
Therefore, it is generally acknowledged that terminal is in wireless environment more severe situation during RLF, now reports wireless environment
Measurement result relatively contributes to network side to carry out coverage optimization.
In the MDT technologies of LTE system, when RLF occurs for UE, it is necessary to which the reference signal for recording serving cell at that time is received
Power (Reference signal received power, RSRP) value and Reference Signal Received Quality (Reference
Signal Received Quality, RSRQ) value and each wireless access type (Radio Access existing at that time
Type, RAT) the optimal adjacent cell of signal intensity signal strength information.By signaling procedure as shown in Figure 2, UE is to network
Report the information i.e. RLF measurement results that RLF is recorded when occurring.
In Fig. 2, RLF measurement results effectively indicate that (1bit) may be embodied in RRC connection re-establishments completion
(RRCConnectionReestablishmentComplete) in message, RRC connections is further included in and set up completion
(RRCConnectionSetupComplete) in message.
The UE of the acquisition RLF measurement results reported are transmitted to tracking result and collect entity (TCE) by network side, are carried out by TCE
Processing, either carries out the network optimization according to RLF measurement results or solves covering problem etc..
In the umts system, RLF is equally existed.RLF Rule of judgment is similar with LTE system to be included：UE physics
Layer reports n times out-of-sync, and rrc layer starts timer, if receiving the n times in- that physical layer is reported before timer expiry
Sync, then cancel timer, otherwise thinks to there occurs RLF in timer expiry.When in addition, for low bit- rate (LCR)
Divide duplexing (Time Division Duplex, TDD), also a kind of situation is considered as RLF：In high speed uplink packet access
In (High Speed Uplink Packet Access, HSUPA), as UE enhanced random ascending control channel (E-
RUCCH transmission times) reaches maximum, and UE rrc layer starts a timer, and the timing length of the timer is N-RUCCH*
T-RUCCH, after the timer expiry, if still not receiving the mandate of network side, then it is assumed that there occurs RLF.E-RUCCH
It is a physical channel, carried terminal data amount information to be sent is used to be used for network side request resource in HSUPA
Row transmission.Can be enhanced insertion authority channel (Enhanced by down physical channel if network side granted resources
Access Grant CHannel, E-AGCH) authorized.If T-RUCCH period of the terminal after E-RUCCH is sent
Mandate is not received inside, then can resend E-RUCCH.T-RUCCH is configured by network side, while network is provided with E-
RUCCH maximum number of times of transmission is N-RUCCH.
In UMTS system, when terminal judges to there occurs RLF, terminal goes to forward pass access channel (Forward Access
Channel, FACH) state, cell selection is performed, (is probably then former in the suitable cell (suitable cell) of selection
Cell is also likely to be new cell) initiate cell update (cell update) process.Cell updating course is as shown in Figure 3.At present
UMTS system does not support RLF to report.
The network side entity that UMTS system includes includes radio network controller (RNC) and base station (Node B).RNC is main
It is responsible for the context and RRM of terminal, is the terminal of RRC signaling, is responsible for parsing RRC signaling.Cell be also by
RNC is managed.Mainly it is responsible for scheduling resource in base station.Terminal mentioned above by E-RUCCH apply resource be exactly by base station come
Authorize.Interface between RNC and base station is referred to as Iub interface.The two can carry out the transmission of some signalings by Iub interface.
Interface between different RNC is referred to as Iur interfaces, and they can carry out Signalling exchange by Iur interfaces.The UMTS network architecture is such as
Shown in Fig. 4, wherein RNS is RNS (Radio Network Subsystem), and UTRAN is that UMTS land is wireless
Access network (UMTS Terrestrial Radio Access Network).
To sum up, when RLF occurs, network side is concern is primarily with wireless environment, to carry out coverage optimization by measurement result.
For LCR TDD systems, the reason for occurring RLF has a variety of, and it is not caused by radio link quality problem to have some.
Such as, when the ascending resource mandate that terminal repeatedly can not receive network side also results in RLF.And in this scene, it may be possible to because
It can not be dispatched to what resource was caused for network side scheduling is busy.If the feelings that now network side is reported still according to normal RLF
Shape, which is handled, notifies terminal to report RLF measurement results, can bring unnecessary operation, and then waste space interface signaling money
