Description
Technical field
The present invention relates to communication technical field, particularly obtain the method and apparatus of positional information in a kind of MDT process.
Background technology
In the mobile communication system in future, wish to reduce the artificial participation of the network planning and Operation and Maintenance by introducing the mechanism of network self-organization, by network based statistic Automatic Optimal parameter, reduce construction and the operation cost of network.
And in order to reduce the O﹠M cost of network, hope can be taked network configuration UE(User Equipment, subscriber equipment, i.e. terminal equipment) report or the network side collection method, reduce the work of artificial drive test.
On the other hand, also wish to obtain the wireless measurement information in the zone that common drive test can't arrive.For these reasons, MDT(Minimization Drive Test, minimum road test) technology is introduced into.
At LTE(Long Term Evolved, Long Term Evolution) Rel-10(Release 10, version 10) in, the MDT that introduces measures classification and comprises following two kinds.
(1) the instant type minimum road test of Immediate MDT().
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)/and RNC(Radio Network Controller, radio network controller) report.
(2) Logged MDT(log type minimum road test).
The MDT that idle (Idle) attitude is carried 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.
In MDT, except some metrical informations are provided, also need to provide the time and the accurate as far as possible geographical location information that took place at that time.
In the prior art, it is independent to have proposed standalone() GNSS(Global Navigation Satellite System, GLONASS (Global Navigation Satellite System)) location technology.
If UE(User is Equipment, subscriber equipment, i.e. terminal equipment) have a GNSS function, as GPS(Global Positioning System, global positioning system), just can directly utilize GPS to obtain the current position of UE, this technology is called standalone GNSS location.
At present, standalone GNSS is mainly enabled by upper layer application, does not also have to support to trigger for the demand of Access Layer.
The A-GNSS(Assisted-GNSS that in the LTE system, introduces, assisted GNSS) method mainly is in order to solve the problem of standalone GNSS search of satellite overlong time, and allows network that some auxiliary datas are provided, allow UE search satellite quickly, thereby earlier position.
Usually, enabling of A-GNSS method also is that upper layer application or third party's positioning client terminal are initiated, not for MDT or AS(Access Stratum, Access Layer) other purposes and trigger.
Whether current UE supports standalone GNSS stationkeeping ability, informs network side as one in the UE ability.But in the prior art, consider power consumption and the complexity of UE, the positional information that MDT is relevant is " best effort(provides as possible) ", if geographical location information is in detail namely arranged effectively, then comprises this geographical location information as a result the time at record; Otherwise record is the metrical information of other adjacent residential quarters (RF fingerprint) at that time, and network side is by these data-evaluations geographical location information at that time, and the position fixing process of not being correlated with especially for the purpose of MDT obtains positional information.
Above-mentioned Immediate MDT and Logged MDT all be that the UE side is carried out the collection of MDT measuring amount, and one of related geographical location information report network side.
Current at QoS(Quality of Service, service quality) verify this MDT use-case, agreed statistics Scheduled IP throughput measuring amount, this measuring amount is carried out by base station side, the geographical position can be reported by the UE side, and detail is not also determined.
Because when carrying out the MDT collection, the positional information that the place measured at that time in record is very important, therefore, is necessary in the WeiLai Technology geographical location information is strengthened.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:
How the detailed geographical location information among the MDT is strengthened, conclusion is not also arranged now.If force to obtain detailed geographical location information by standalone GNSS location, can not bring complexity to network side, and precision height, but not all UE possesses standalone GNSS stationkeeping ability, and at indoor scene, GNSS signal attenuation is big, can not use standalone GNSS to position.In addition, even terminal possesses standalone GNSS stationkeeping ability, also may can only be by certain applications trigger of UE, and can not be triggered by the Access Layer of network.

Embodiment
As stated in the Background Art, the MDT technology is a kind of in order to reduce the O﹠M cost of network, take the network self-organization mechanism that the network configuration terminal equipment reports or the network side collection method realizes, it reduces the work of artificial drive test, and in MDT, except some metrical informations are provided, also need to provide the time and the accurate as far as possible geographical location information that took place at that time, but, also do not have in the prior art a kind of detailed geographical location information among the MDT to be strengthened, thereby obtain the scheme of accurate more geographical location information.
In order to overcome such defective, the embodiment of the invention has proposed to obtain in a kind of MDT process the method for positional information, report self whether to have by terminal equipment and can be used the ability information of standalone GNSS location by network-triggered, the base station can be decided according to the ability of terminal equipment how to obtain positional information, the detailed geographical location information when guaranteeing in time to obtain to carry out the MDT process.
As shown in Figure 1, obtain the schematic flow sheet of the method for positional information in a kind of MDT process that proposes for the embodiment of the invention, this method specifically may further comprise the steps:
Step S101, when base station selected when terminal equipment is carried out the MDT task, described base station judges whether described terminal equipment supports standalone GNSS location.
If support, then execution in step S102;
If do not support, execution in step S104 then.
In the deterministic process of this step; whether terminal equipment supports standalone GNSS location to judge according to the ability information that terminal equipment reports in advance; certainly; if in the base station, register or backed up the ability information of each terminal equipment in advance; then above-mentioned ability information also can no longer report, and such variation does not influence protection scope of the present invention.
Step S102, described base station judge whether and can carry out standalone GNSS location by the described terminal equipment of network-triggered.
If judged result is not, then execution in step S103;
If judged result is for being, execution in step S104 then.
S101 is similar with step; in the deterministic process of this step; whether can carry out standalone GNSS location by the described terminal equipment of network-triggered need judge according to the ability information that terminal equipment reports in advance; certainly; if in the base station, register or backed up the ability information of each terminal equipment in advance; then above-mentioned ability information also can no longer report, and such variation does not influence protection scope of the present invention.
By the judgement of this step, the base station can determine whether self can open standalone GNSS location by control terminal.
Step S103, described base station selected other locate modes are obtained described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
Wherein, need to prove, if in aforesaid step S102, described base station is judged and cannot be carried out standalone GNSS location by the described terminal equipment of network-triggered, so, above-mentioned step S104 can also further carry out corresponding differentiated treatment according to the current state information of this terminal equipment, specifies as follows:
If this terminal equipment is under the connection mode, then described base station selected other locate modes are obtained described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
If this terminal equipment is under the Idle state, then described base station disposes described terminal equipment and only just carries out the MDT process under the situation of opening standalone GNSS location.
Step S104, described base station dispose described terminal equipment and open standalone GNSS location when carrying out the MDT process, to obtain described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
In the application scenarios of reality, the processing procedure of this step can also further comprise following handling process:
Described base station determines whether to trigger described terminal equipment unlatching standalone GNSS location according to the prior information of the current area that described terminal equipment belongs to.
Such process specifically can be divided into two kinds of situations:
If situation one described base station judges that according to the prior information of the current area that described terminal equipment belongs to the residing position of current area exists signal to stop, or inconvenience reception GNSS signal, then wouldn't trigger described terminal equipment and open standalone GNSS location.
For example, if current area is indoor coverage cell, perhaps high rise building dense, then triggering terminal device start standalone GNSS location not.
If situation two described base stations judge that according to the prior information of the current area that described terminal equipment belongs to the residing position of current area can normally receive the GNSS signal, then trigger described terminal equipment and open standalone GNSS location all the time.
For example, if current area is in the spacious area that can receive the GNSS signal, then directly configurating terminal device starts standalone GNSS location.
On the other hand, the ability information of considering terminal equipment self has just shown the support of terminal equipment for network-triggered standalone GNSS location, but, because network transmission environment, the terminal equipment self-ability changes and other external force are disturbed, the capability state of this terminal may be affected, cause this ability normally to realize, therefore, after above-mentioned step S104 finishes, can further include the execution proof procedure of following standalone GNSS location, concrete, on the basis of before step S104, the schematic flow sheet of corresponding processing procedure specifically may further comprise the steps as shown in Figure 2:
The current standalone GNSS location of whether can normally carrying out of described terminal equipment is judged in step S105, described base station.
If of course, execution in step S106 then;
If cannot, then return execution in step S103.
Need to prove that in the application scenarios of reality, in this step, the current foundation that cannot normally carry out standalone GNSS location of described terminal equipment is judged in described base station, comprises one or more following situations at least:
When (1) the described terminal equipment of described base station triggers is carried out standalone GNSS location, start a timer, but before described timer expiry, described base station does not get access to described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
When (2) the described terminal equipment of described base station triggers is carried out standalone GNSS location, start a counter, but when the count value of described counter reaches maximum times, described base station does not still get access to described terminal equipment corresponding detailed geographical location information when carrying out the MDT process, wherein, in described MDT process, described terminal equipment whenever reports the one-shot measurement value, and described base station adds up one with the count value of described counter.
(3) after the described terminal equipment of described base station triggers was opened standalone GNSS location when carrying out the MDT process, described base station received the indication that can't carry out the GNSS location that described terminal equipment reports.
(4) after the described terminal equipment of described base station triggers is opened standalone GNSS location when carrying out the MDT process, described base station does not receive the latitude and longitude information that described terminal equipment reports, but receives the RF fingerprint(radio-frequency fingerprint that described terminal equipment reports) measurement result.
In the application scenarios of reality; the above-mentioned several foundations of concrete employing; can set according to the actual needs; and other can determine that terminal equipment can not normally carry out the foundation of standalone GNSS location; can be applied to the technical scheme that the embodiment of the invention proposes too, such can't influence protection scope of the present invention according to content change.
Step S106, the described terminal equipment of described base station triggers are opened standalone GNSS location when carrying out the MDT process.
Need further be pointed out that, in above-mentioned processing procedure, step S103 adopts triggering terminal opening of device standalone GNSS location mode in addition by making the base station, obtain terminal equipment corresponding detailed geographical location information when carrying out the MDT process, in the application scenarios of reality, such mode can have a lot, every effect mode of obtaining that makes the base station carry out detailed geographical location information that can reach all can be applied to technical scheme proposed by the invention, in the present embodiment, can realize obtaining of detailed geographical location information by following dual mode at least.
Mode one, described base station are by the autonomous TA(TATiming Advance that triggers, Timing Advance)+AoA(Angele of Arrival, arrival bearing) mode is obtained described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
In existing technical scheme, CELL_ID(cell ID) localization method is based on the localization method that the residential quarter covers, the position of adopting known Serving cell geography information estimating target UE.This service cell information can be by calling, paging, TA(Tracking Area, tracking area) mode such as district's renewal obtains.
TA+AoA has considered Timing Advance (being TA) and arrival bearing's's (being AoA) factor on the basis of CELL_ID localization method, thereby reaches more accurate localization purpose.
The base station obtains the AoA that UE transmits by smart antenna, and it is on the ray of starting point that UE is in eNB, and the angle that ray is rotated counterclockwise from direct north is AoA.
The acquisition of TA can add that reception that the base station measures and the time difference of transmission calculate (TA that the method calculates is referred to as TA TYPE1) by the time difference that terminal to report UE receives and sends among the LTE, also can obtain (TA that the method calculates is referred to as TA TYPE2) by base station measurement by special-purpose random access procedure.TA multiply by the light velocity divided by 2, has represented UE with the distance between the base station, and it is that the center of circle, terminal and base station distance are on the circumference of radius that UE just is in the base station.Angle information according to AoA just can obtain location information of terminals again, according to the resulting schematic diagram of above-mentioned positioning principle as shown in Figure 3.
The localization method of TA+AoA only is used for based on network location usually, main cause is that AoA can only be obtained by base station measurement, TA TYPE1 and TA TYPE2 are calculated or are measured by the base station, and namely all measuring amount relevant with this localization method all are that the base station provides.
Therefore, though the positioning result that the TA+AoA localization method obtains does not have GNSS precision height, an advantage of this method is, for the terminal of support location service not, also can position it by this method.
Based on above explanation, terminal equipment not network enabled trigger to use standalone GNSS location, or under the current situation that can't normally carry out standalone GNSS location of terminal equipment, can adopt the localization method of TA+AoA to realize obtaining of detailed geographical location information.
Mode two, described base station are passed through self as LCS(LoCation Service, positioning service) client, and the mode of triggering LCS positioning flow, obtain described terminal equipment corresponding detailed geographical location information when carrying out the MDT process.
Such mode is based on the method that mobile communications network obtains the position of terminal equipment, can terminal equipment not network enabled trigger to use standalone GNSS location, or under the current situation that can't normally carry out standalone GNSS location of terminal equipment, be used for carrying out terminal equipment the obtaining of corresponding detailed geographical location information when carrying out the MDT process.
Need to prove; above-mentioned dual mode is the alternative of adaptable standalone GNSS location in the practical application scene; namely terminal equipment not network enabled trigger to use standalone GNSS location; or under the current situation that can't normally carry out standalone GNSS location of terminal equipment; carry out obtaining of detailed geographical location information; concrete which kind of mode of selecting; and whether adopt other modes that can reach same technique effect, all can not influence protection scope of the present invention.
