Description
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of location information acquisition method and equipment.
Background technology
At present, the method that terminal (UE) positions is as follows:
If UE has GPS (Global Navigation Satellite System, GNSS)
Function, such as global positioning system (Global Positioning System, GPS) function, can direct profit
Obtaining the current position of UE with GPS, this method is referred to as independent GPS
(standalone GNSS) positions.
Owing under GNSS cost height and indoor scene, GNSS signal fading ratio is bigger, it is proposed that based on shifting
Dynamic communication network obtains the method for the position of UE, including positioning service (LoCation Service, LCS)
Method, TA+AoA localization method, observed time difference (the Observed Time Difference Of at arrival angle
Arrival, OTDOA) localization method and the GPS localization method of network assistance
(A-GNSS) etc..
LCS chain of command positioning flow in Long Term Evolution (LTE) system is as shown in Figure 1:
Step 1. Mobility Management Entity (MME) receives request for location services, and this request for location services can
To be the UE request of passing through that Non-Access Stratum (NAS) message is initiated to MME, it is also possible to be EPC (Evolved
Packet Core, the packet-based core networks of evolution) in some entities (such as GMLC (Gateway
Mobile Location Center, GMLC)) or the internal request for location services initiated of MME；
Request for location services is issued the Serving Mobile Location Center (Evolved of evolution by step 2.MME
Serving Mobile Location Center, E-SMLC), E-SMLC takes according in this request for location services
Service quality (QoS) information (such as information such as the precision positioned and time delays) of band selects the suitably side of location
Method；
Step 3a.E-SMLC may be by additional (the LTE Positioning Protocol of LTE location protocol
Annex, LPPa) to trigger base station (eNB) relevant position fixing process (as auxiliary in obtain needed for location for agreement
Help the measurement needed for data or location)；
Step 3b.E-SMLC may pass through LTE location protocol (LTE Positioning Protocol, LPP)
Trigger relevant for UE position fixing process (as obtain the assistance data needed for location estimation, transmission location or
Obtain the measurement needed for location)；
Step 4.E-SMLC to MME send positioning service response, in the middle of include some required results
(such as the position of UE, the instruction etc. of location success or failure)；
Positioning service response is returned to target entity by step 5.MME.
As can be seen here, use LCS location mode to obtain the positional information of UE, need multiple network node to enter
Row is mutual.
TA+AoA localization method is the localization method based on cell ID (CELL ID) of a kind of enhancing.
CELL ID localization method is localization method based on MPS process, uses known Serving cell geography information
Estimate the position of target UE.This service cell information can pass through calling, paging, tracking area (Tracking
Area, TA) mode such as renewal obtains.TA+AoA localization method is on the basis of CELL ID localization method
On consider Timing Advance (Timing Advance, TA) and arrival bearing (Angele of Arrival,
AoA) factor, thus reach to position more accurately purpose.
AoA, UE that base station obtains UE transmitting signal by smart antenna are in penetrating with eNB as starting point
On line, and ray is AoA from the angle that direct north rotates counterclockwise；
In LTE system, the acquisition of TA can report this UE to receive by UE and the time difference of transmission adds
Reception and the time difference of transmission that base station measures calculates that (the calculated TA of the method is referred to as TA class
Type 1 (TYPE1)), it is also possible to obtained (the method calculating by special random access procedure by base station measurement
The TA obtained is referred to as TA TYPE2).TA is multiplied by the light velocity divided by 2, illustrate UE with base station between
Distance, UE is at base station as the center of circle, on terminal and the base station distance circumference as radius.Further according to AoA
Angle information be obtained with the positional information of terminal, as shown in Figure 2.
The localization method of TA+AoA is generally only used for network location, and main cause is that AoA can only
Being obtained by base station measurement, TA TYPE1 and TA TYPE2 is also to be calculated by base station or measured to obtain, i.e.
All measurement amounts relevant to this localization method are all that base station provides.Therefore, although TA+AoA location side
The positioning result that method is obtained does not has GNSS precision high, but the method advantage is, for not propping up
Hold the terminal of positioning service, it is also possible to by the method, it is positioned.
In following mobile communication system, it is desirable to by introducing the mechanism of network self-organization, reduce network rule
Draw and the artificial participation of Operation and Maintenance, by network according to statistic Automatic Optimal parameter, reduce the construction of network
And operation cost.In order to reduce the O&M cost of network, it is desirable to be able to take network configuration UE to report or
Network side collection method, reduces the work of artificial drive test.On the other hand, it is also desirable to be obtained in that common drive test
The wireless measurement information in the region that cannot arrive.For these reasons, minimize drive test (MDT) to be introduced into.
The MDT introduced in technology at present measures classification to be had:
Instant MDT (Immediate MDT) measures: UE the MDT that connected state is carried out measure with
Report.
Record MDT (Logged MDT) is measured: the MDT that UE is carried out at Idle state measures, rear
Continuous connected state reports.Once meet the trigger condition of configuration, by acquisition measurement result and store
(log), base station/radio network controller (eNB/RNC) is reported at follow-up proper moment.
Above-mentioned Immediate MDT and Logged MDT, is all that UE side carries out the collection of MDT measurement amount,
And associate geographical location information one piece and report network side.Currently verify this MDT use-case for QoS,
Agree to add up IP handling capacity (Scheduled IP throughput) measurement amount based on scheduling, this measurement amount
Being performed by base station side, geographical position can be reported by UE side.
Whether current UE supports standalone GNSS stationkeeping ability, as one in R10UE ability
Informing network side.But in prior art, it is contemplated that the power consumption of UE and complexity, position letter relevant for MDT
Breath provides as possible, if i.e. there being effective geographical location information in detail, then includes this when recording result
Geographical location information；Otherwise, record radio frequency footprint (RF fingerprint), content is other adjacent cells at that time
Metrical information, network side passes through these data-evaluations geographical location information at that time, not for MDT
Purpose and the position fixing process that carries out especially being correlated with to obtain positional information.Therefore current standalone GNSS
Mainly enabled by upper layer application, the most do not support that the demand for Access Layer (such as MDT) triggers.
During owing to carrying out the collection of MDT measurement amount, the positional information at UE place measured at that time in record is the heaviest
Want, therefore WeiLai Technology is necessary geographical location information is strengthened.
How the detailed geographical location information in MDT is strengthened, the most also do not have conclusion.If it is logical
Cross standalone GNSS location and force to obtain the detailed geographical location information of UE, will not be to network side band
Carry out complexity, and precision be high, but not all UE possesses standalone GNSS stationkeeping ability,
And at indoor scene, GNSS signal decay is big, and standalone GNSS can not be used to position.
