Description
Technical field
The present invention relates to communication technical field, particularly a kind of RLF recording of information method and apparatus.
Background technology
LTE MDT (Minimization Drive Test, minimum road test mechanism) comprises following use-case at present:
1, Coverage optimization (coverage optimization)
2, Mobility optimization (mobility optimization)
3, Capacity optimization (capacity optimization)
4, Parameterization for common channels (common signal channel parameter optimization)
5, QoS verification (quality of service checking)
In research report TR 36.805 V9.0.0 of the MDT based on R9 version completing for 2009 at 3GPP, determined following 7 terminal equipment measuring amount:
1, Periodical downlink pilot measurements (cycle descending pilot frequency is measured)
2, Serving Cell becomes worse than threshold (it is poorer than setting thresholding that service district becomes)
3, Transmit power headroom becomes less than threshold (it is poorer than setting thresholding that PHR becomes)
4, Random access failure (random access failure)
5, Paging Channel Failure (paging channel takes defeat)
6, Broadcast Channel failure (broadcast channel takes defeat)
7, Radio link failure report (Radio Link Failure report)
Measuring amount defined above is for Different Optimization use-case, such as RLF (Radio Link Failure, Radio Link Failure) failure can application and coverage optimization and mobility optimization.
Except above-mentioned 7 measuring amount, in follow-up standard process, do not get rid of the measuring amount that increases other, as the relevant measuring amount of the QoS of terminal equipment (Quality of Service, service quality).
At present, in LTE, have three kinds of scenes can impel terminal equipment that RLF occurs:
1, descending long-time step-out
2, RACH (Random Access Channel, Random Access Channel) failure
3, RLC (Radio Link Control, wireless link is controlled) retransmits and reaches maximum times
Current SON (Self Organising Networks, the mechanism of network self-organization)-MRO (Maintenance Repair & Operations, maintenance, repair and operation) terminal equipment is not distinguished is the RLF that situation causes, once terminal device records RLF information, will in reconstruction completes, report RLF available.Concrete process is as follows: if terminal equipment detects RLF, RSRP (the Reference Signal Received Power of community before and after the cell ID occurring while recording RLF and RLF, reference signal receiving ability)/RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) information; Next terminal equipment carries out community process of reconstruction, if rebuild successful terminal equipment, in reconstruction, completes and in community, carries RLF and record criterion and know, and network based this information triggering terminal equipment in suitable carries out RLF recorded information and reports.
The process of reconstruction occurring after RLF due to terminal equipment can be not successful, at this moment terminal equipment will enter idle (idle condition), terminal equipment carries out RRC with network again and is connected process of establishing, therefore also the effective information of terminal device records RLF can be put in RRC connection setup complete message.
In MDT, also there is RLF use-case, but also do not determine at present it is RLF report or the independent design RLF reporting process just adopting in SON.
In realizing process of the present invention, inventor finds that prior art at least exists following problem:
Due to current terminal equipment, do not distinguish the RLF of what situation, namely do not record the reason of RLF, and offer network, when the network based like this RLF record reporting is up optimized network, likely produce irrational optimum results.
Such as, terminal equipment is indicated RLF record effectively in reconstruction, and network does not have indicating terminal equipment to switch, and terminal equipment is reconstituted in this community.At this moment due to RACH problem or up covering RLC problem generation RLF, terminal equipment Zhe community rebuilds successfully, and before network based RLF, RSRP judged whether to switch late or descending covering leak.At this moment the RSRP recording before and after RLF when terminal equipment is identical, and it is excessively slow that network can be judged as switching, but at this moment because RACH problem or up covering problem cause, so this is the information of obscuring to network.
Also such as, terminal equipment enters idle, is being successfully established middle indication RLF.At this moment due to RACH problem or up covering RLC problem generation RLF.Terminal equipment enters and carries out RRC after idle and connect and be based upon this community or be based upon other communities, and before network based RLF, RSRP judged whether to switch late or descending covering leak.At this moment the RSRP recording before and after RLF when terminal equipment is identical, and it is excessively slow that this network can be judged as switching, but at this moment because RACH problem or up covering problem cause, so this is the information of obscuring to network.
Therefore can find out when up covering leak, if what situation terminal equipment does not distinguish, not report and can cause network erroneous judgement.
