Description

Location survey and positional information preparation method, system and equipment
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of location survey and positional information preparation method, system and equipment.
Background technology
In the mobile communication system in future, wishing the mechanism by introducing network self-organization, reducing the artificial participation of the network planning and Operation and Maintenance, by network according to statistic optimize parameters au tomatically, reduce construction and the operation cost of network.In order to reduce the O&M cost of network, wishing the method that network configuration terminal (UE) can be taked to report, reducing the work of artificial drive test, be i.e. minimum road test (MDT) scheme.On the other hand, the wireless measurement information that can be obtained the region that common drive test cannot arrive by MDT is also wished.
MDT is applied to Long Term Evolution (LTE) and universal mobile telecommunications system (UMTS) system.According to the reporting schemes of MDT result, MDT is divided into real-time MDT (Immediate MDT) and record MDT (Logged MDT), specific as follows:
Immediate MDT is that UE carries out MDT measurement at connected state and reports.Multiplexing RRM (RRM) measurement mechanism, once meet report condition, reports to base station/radio network controller (eNB/RNC) immediately.Existing Immediate MDT reports trigger unit to be shaped with periodic triggers MDT measurement and to report and event triggers MDT measurement and reports.
Logged MDT measurement is that UE carries out MDT measurement at Idle state, reports at follow-up connected state.Once meet the trigger condition of configuration, acquisition measurement result is carried out storing (log).After UE enters connected state from Idle state, report log can report the MDT measurement result of storage at request of suitable time UE according to own situation to eNB/RNC, eNB/RNC with instruction (log available).
If UE has global navigation satellite (GNSS, Global Navigation Satellite System) function, as global positioning system (Global Positioning System, GPS), GPS can be directly utilized to obtain the current position of UE.Due to GPS cost is high and under indoor scene gps signal fading ratio larger, there has been proposed the method for the position obtaining terminal UE based on mobile communications network, i.e. positioning service (LoCation Service, LCS), usually have cell ID (Cell ID) and strengthen, the GPS (Global Position System) localization method (A-GNSS) etc. of observation signal poor (Observed Time Difference OfArrival, OTDOA) the method time of advent and network assistance.
LCS chain of command positioning flow in LTE system as shown in Figure 1, specifically comprises the following steps:
Step 1: Mobility Management Entity (MME) receives request for location services, this request for location services can be the request that UE is initiated to MME by Non-Access Stratum (NAS) message, also can be that some entities in the packet-based core networks (EPC) of evolution are (as request for location services is initiated in GMLC (Gateway MobileLocation Center, GMLC) or MME inside;
Request for location services is issued the Serving Mobile Location Center (E-SMLC) of evolution by step 2.:MME, and E-SMLC selects suitable localization method according to the service quality of carrying in this request for location services (QoS) information (precision and the information such as time delay as location);
Step 3a:E-SMLC locates Additional Agreement (LTE Positioning Protocol Annex by LTE, LPPa) position fixing process that trigger base station (eNB) is relevant, as obtained the auxiliary data needed for location or the measurement result needed for location;
Step 3b:E-SMLC is by LTE location protocol (LTE Positioning Protocol, LPP) the relevant position fixing process of UE is triggered, as the auxiliary data obtained needed for location estimation result, transmission location or the measurement result obtained needed for location;
Step 4:E-SMLC sends positioning service response to MME, includes result needed for some in this positioning service response, as UE position, locate successfully or failed instruction etc.;
Positioning service response is returned to target entity by step 5:MME.
Wherein, in step 3a, LPPa agreement supports that eNB periodically reports the measurement result needed for location; In step 3b, LPP agreement supports that UE periodically reports location estimation result or the measurement result needed for location, in addition for enhancement type district mark (Enhanced Cell-ID, E-CID) locate, support when community change trigger UE report location estimation result or location needed for measurement result.It should be noted that, step 3a and step 3b is optional step.
UMTS positioning flow as shown in Figure 2, specifically comprises the following steps:
Step 1: after core net position determining entity receives Location Request, Location Request is sent to service radio network controlled entity (SRNC), this Location Request can be the request for location services that UE, GMLC or network internal are initiated to core net position determining entity;
Step 2:SRNC sends positioning measurement command by wireless heterogeneous networks (RRC) signaling to UE;
The positioning measurement result of acquisition or location estimation result are returned to SRNC by step 3:UE;
Step 4:UMTS be positioned with centered by radio network controller (RNC) with stand-alone service mobile location centre Chinese (Stand-Alone SMLC, SAS) centered by two kinds of patterns.Under pattern centered by RNC, SRNC completes the calculating of location estimation; Under pattern centered by SAS, SRNC locates SAS, carries out location estimation by SAS, as shown in empty frame;
Location estimation result is reported core net (CN) by step 5:SRNC.
In step 3, UE supports periodic reporting measurement or location estimation result, also support that event triggers reporting measurement or location estimation result, comprise the change of UE position and be greater than certain absolute value, SFN-SFN (System Frame Numbe, System Frame Number) measured value changes and is greater than certain absolute value, gps time and SFN time drift amount and is greater than certain absolute value and Galileo and other satellite navigation systems (Galileo andAdditional Navigation Satellite System, GANSS) time and SFN time drift amount and is greater than certain absolute value.
When MDT measures, if geographical location information at that time can be obtained, then can better carry out liberalization by auxiliary network, the particular geographic area that problem identificatioin occurs, draw and cover map (coverage mapping) etc.But consider UE ability and obtain geographical location information and can bring power consumption, and coordination LCS locates the complexity brought, when in R10, UE reports MDT measurement result, do not force to provide accurate geographical location information, but take " best-effort " (doing one's best) mode, namely, when UE records MDT measurement result, if there is available precise position information, then it can be used as the positional information content reported; If there is no available precise position information, then UE needs reporting radio frequency footprint (Radio Frequencyfingerprint, RF fingerprint) information, the PCI/PSC+ RSRP/CPICH RSCP(comprising 6 co-frequency neighbor cells at the most wherein PCI/PSC is physical-layer cell identifier, RSRP/CPICH RSCP is received signal power), the signal strength measurement of surrounding's adjacent cell that network side can report according to UE, derives the position that UE is general at that time.
Realizing in process of the present invention, inventor finds to there is following technical problem in prior art:
At present, only have periodic triggers and simple several event triggering terminal or base station to carry out LCS location survey, triggering mode is more single.
When UE reports MDT measurement result, available precise position information or RF fingerprint information are reported network side as the positional information of UE, and this positional information is not the real-time position information that UE carries out when MDT measures, and accuracy is poor.
