Description

A kind of system of selection of MDT locate mode and equipment

Technical field

The present invention relates to communication technical field, particularly a kind of system of selection of MDT locate mode and equipment.

Background technology

In LTE (Long Term Evolution, Long Term Evolution) Rel-10 (Release 10, version 10), the MDT that is introduced (Minimization Drive Test, minimum road test) measures classification and comprises following two kinds.

(1) Immediate MDT (instant type minimum road test).

The MDT that connected state carries out measures and reports.Multiplexing RRM (Radio Resource Management; RRM) measurement mechanism, in case satisfy report condition, immediately to eNB (evolved Node B; Evolved base station)/RNC (Radio Network Controller, radio network controller) reports.

(2) Logged MDT (log type minimum road test).

The MDT that Idle state carries out measures, and reports at follow-up connected state.In case satisfied the trigger condition of configuration, will obtain measurement result and store (log), report eNB/RNC on follow-up suitable opportunity.

It all is the enhancing to coverage optimization that these two types of MDT measure.And at Rel-11, the MDT measuring amount is strengthened, except the coverage optimization measuring amount, also introduced measuring amount, like throughput etc. to QoS (Quality of Service, service quality) verification (affirmation).

In Rel-10; Consider UE (User Equipment; Subscriber equipment, i.e. terminal equipment) power consumption and complexity, the positional information that MDT is relevant is that " best effort (best effort) " provides; Be that the terminal provides the effective geographical location information when carrying out the MDT measurement as far as possible, do not introduce the position fixing process of being correlated with especially and obtain positional information for the purpose of MDT.Because when the MDT measurement was carried out at the terminal, the positional information that the place measured in record was very important, therefore, the project among the Rel-11 MDT is designated as the enhancing geographical location information.

At present, Rel-11 MDT has launched discussion, clear and definite all will do detailed geographical location information to Immediate MDT and Logged MDT and strengthens, but how to strengthen conclusion is not arranged also.

On the other hand, about location technology, the concrete introduction as follows.

If UE has GNSS (Global Navigation Satellite System; Global navigation satellite) function; Like GPS (Global Positioning System; Global positioning system), can directly utilize GPS to obtain the current position of UE, this standalone (independence) the GNSS location that is called.

Because gps signal fading ratio is bigger under GPS cost height and the indoor scene; Further proposed to obtain the method for the position of terminal UE based on mobile communications network; Be LCS (LoCation Service; Positioning service); Usually have Cell ID (cell ID) and enhanced positioning method thereof, OTDOA (Observed Time Difference of Arrival, observation arrives the time difference) localization method and network assistance the GPS localization method (Assisted-GNSS, A-GNSS) etc.

As shown in Figure 1, the sketch map for LTE LCS chain of command positioning flow of the prior art specifically may further comprise the steps:

Step S101, MME (Mobility Management Entity; Mobility Management Entity) receives request for location services; This services request can be that UE passes through NAS (Non Access Stratum, Non-Access Stratum) message to the request that MME initiates, and also can be EPC (Evolved Packet Core; Evolution block core) the inner request for location services of initiating of some entities in (like GMLC (Gateway Mobile Location Center, GMLC)) or MME.

Step S102, MME issue E-SMLC (evolution Serving Mobile Location Center with request for location services; Evolved-Serving Mobile Location Center), E-SMLC selects suitable localization method according to the QoS that carries in this Location Request (like information such as locating accuracy and time delays);

Step S103a, E-SMLC through LPPa (LTE Positioning Protocol a, LTE location protocol a) agreement possibly trigger the relevant position fixing process of eNB (as obtain the required auxiliary data in location, or locate required measurement).

Step S103b, E-SMLC through LPP (LTE Positioning Protocol, LTE location protocol) agreement possibly trigger the relevant position fixing process of UE (as obtain the required auxiliary data of location estimation, transmission location, or obtain the required measurement in location).

Step S104, E-SMLC send the positioning service response to MME, in the middle of comprised some required results (, locating successfully or the indication of failing etc.) like the position of UE.

Step S105, MME return to target entity with the positioning service response.

This shows that if adopt the LCS locate mode to obtain the UE positional information, UE need be in connected state, and UE need carry out with a plurality of network nodes alternately.

In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:

Rel-10 and before the LTE system in, the UE ability that UE reports to eNB mainly comprise UE physical layer ability, RF capabilities, measurement capability, whether support log MDT, whether support the ability of standalone GNSS location etc.ENB also can't be known the relevant ability in 3GPP (Third Generation Partnership Project, 3G (Third Generation) Moblie gpp) location of UE at present, and the 3GPP stationkeeping ability of UE mainly is that UE and E-SMLC node are known.And do not have scheme can support eNB to obtain the 3GPP located in connection ability of UE at present yet.When eNB can't be known the stationkeeping ability of UE, eNB also can't select suitable MDT locate mode for UE.

Therefore; In the prior art; Because eNB can't be known the relevant ability in 3GPP location of UE, also just can't cause under some scene for UE selects suitable MDT locate mode; Can't obtain the geographical location information of UE, can not realize that the MDT of Rel-11 is to the requirement of geographical location information when obtaining (be MDT measuring amount also relevant geographical location information will be arranged).

Suppose that UE self supports three kinds of localization methods: standalone GNSS, ECID and OTDOA, and the correlation energy of UE is tried hard to keep and is existed among the eNB of source.

When switching, source eNB passes to target eNB through X2 or S1 message with this ability, and after switching was accomplished, target eNB became the service eNB of this UE.

Follow-up this UE is when connected state, and service eNB selects this UE to carry out MDT, and then eNB carries out the relevant location of MDT for UE selects the OTDOA method, and notifies to UE through the MDT configuration messages according to three kinds of locate modes being supported in the UE ability.

Further, if in the UE ability, the priority of three kinds of locate modes is OTDOA, ECID and standalone GNSS from high to low, and then eNB obtains after this information, will preferentially select the OTDOA method to be used for the MDT location.

Embodiment five, UE do not support the location.

UE itself does not support the location, reports in the UE ability and does not carry any location correlation energy force information in the process.

Follow-up this UE is when connected state, and eNB selects this UE to carry out MDT, and then eNB can adopt the localization method (like UTDOA) of network side to obtain the positional information of this UE, and then carries out related with the MDT measuring amount of UE.
