Embodiment
MDT measures except reporting the wireless environment situation that satisfies above-mentioned situation, also need confirm and report the geographical location information of UE at that time.The obtain manner of UE positional information can comprise usually: if UE has autonomous 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.Because gps signal fading ratio is bigger under GPS cost height and the indoor scene, proposed to obtain the method for the position of UE at present, i.e. LCS (LoCation Service, positioning service) based on mobile communications network.LCS generally includes following several kinds of location technologies:
(1) based on Cell ID (cell ID) location, that is, combine other metrical informations through known Serving cell geography information, calculate the position of UE, like the TA+AOA method;
(2) UE monitors the pilot signal of a plurality of base stations simultaneously, obtains the time difference that signal arrives between the base station, confirms the position of UE through plural Hyperbolic Equation, like the OTDOA method;
(3) the GPS localization method (A-GNSS) of network assistance.Wherein GPS comprises GPS, Galileo and other possible navigation systems.The A-GNSS method is the work simplification of UE, cooperatively interacted by the location Calculation center of network side and UE and accomplishes location work.Can estimate the overhead satellite transit situation in this position according to the preliminary position of UE like network side,, and send to UE like ephemeris (ephemeris), almanac (almanac) and difference calibration information etc.UE can be optimized search and position fixing process as priori with it, reduces search time, reduces effect such as search signal level demand thereby play, and improves positioning performance.
The positional information of in the MDT measurement report, carrying UE can the auxiliary network side be optimized; But consider the influence of location to UE; In the prior art, the positional information among the MDT adopts " best-effort " (doing one's best) mode, promptly when UE reports the MDT measurement result; Can carry the geographical location information of usefulness, perhaps other information is so that can derive the geographical position of UE at that time.As in existing conclusion; If available GNSS positional information is arranged, then when reporting the MDT measurement report, carry this positional information, if do not have; Then report RF fingerprint information, network side can obtain the position of UE through this RF fingerprint information inference.Concrete regulation comprises:
During Logged MDT measured, the following geography information that network relies on UE to report identified the sub-district and the position of UE in this sub-district at UE place:
Measure the ECGI (E-UTRAN Cell Global Identifier, E-UTRAN sub-district overall identification) of Serving cell when taking place, be essential option;
If the GNSS positional information can be used when measuring generation, then as the positional information content that reports, the GNSS positional information that reports comprises longitude and latitude, if available, also can comprise height;
If the GNSS positional information is unavailable when measure taking place, UE need report RF fingerprint information, comprising: the PCI/PSC+RSRP/CPICH RSCP of 6 co-frequency neighbor cells at the most.The signal strength measurement of the adjacent sub-district, this surrounding, position that network side can report according to UE is derived the general at that time position of UE.
In addition, stipulated that also the position information process mode among the immediate MDT is the same with Logged MDT processing mode.
But in mobile communications network, the acquisition mode of UE position can also obtain through the Signalling exchange of mobile network's side except the autonomous GNSS of UE locatees, and promptly LCS obtains the UE current position information.And in the present regulation, when the positional information among the MDT adopts " best-effort " mode, do not comprise the situation of LCS positional information.
Problem to above prior art existence; The embodiment of the invention provides a kind of MDT position information process mechanism; When making the MDT measurement and report more accurate positional information can be provided as far as possible, thereby can satisfy the needs of network self-organization, improve the effect of network self-organization.
In the MDT position information process mechanism that the embodiment of the invention provides, when MDT measured generation, if the LCS positional information of UE can be used, then UE noted it as current MDT measurement corresponding position information, and in subsequent process, reports network side.
In brief, the flow process of the MDT position information processing method that the embodiment of the invention provided can be as shown in Figure 1, comprising:
To combine accompanying drawing below, the technical scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the present invention protects.
Embodiment one
Referring to Fig. 2, the UE that present embodiment provides reports the flow process of its location dependent information through the MDT measurement report, and this flow process can may further comprise the steps:
Step 201, UE receives the immediateMDT configuration information that E-UTRAN (evolution-land radio access web) sends, and uses this configuration information and carries out the MDT measurement configuration, and start immediate MDT measurement.
Step 202; (want to know the positional information of oneself like the user) for a certain reason; UE begins the LCS position fixing process, thereby obtains own current position information, and the LCS position fixing process can be through realizing with E-SMLC (evolution-Serving Mobile Location Center) alternately.UE stores the LCS positioning result get off, and opening timing device T1 (timing length of timer T1 can set up on their own, can be fixed value; Like 10s; Also can change according to the current motion state of UE and set, as at a slow speed UE (3km/h), timer T1 can be set to about 20s; For UE (30km/h) fast, timer T1 can be set to about 5s).
Step 203～204, subsequently, owing to satisfy periodicity or trigger conditions, UE need report the MDT measurement report, if this moment, UE recorded useful LCS positioning result, then in the MDT measurement report, carries this LCS positioning result and reports network side.Wherein, under the not overtime situation of timer T1, the LCS positioning result that UE write down can be considered to useful positioning result; Further, consider required precision, and positioning accuracy LCS positioning result not overtime at timer T1 meets under the situation of required precision, can the LCS positioning result that UE write down be regarded as useful positioning result.
UE obtains the locating information except adopting the LCS mode, also can adopt other modes to obtain locating information, and to this situation, this step can also be embodied as:
Under the not overtime situation of timer T1; UE had both recorded the LCS positioning result; Also record the useful positions information that UE obtains through autonomous locate modes such as GNSS; Then UE judges the positioning result up-to-date (promptly nearest apart from the current time) which kind of mode obtains, and selects up-to-date positioning result to be filled in the MDT measurement report as useful positions information.Further, consider required precision, UE can judge after judging up-to-date positioning result whether this positioning result meets required precision, if meet, thinks that then this positioning result is useful positioning result and inserts the MDT measurement report; Otherwise thinking does not have useful positioning result, thereby reports information such as RF fingerprint;
Under the not overtime situation of timer T1; UE records the LCS positioning result; But do not record the useful positions information that obtains through autonomous locate modes such as GNSS (like the positional information of recent record; Perhaps recent write down and positional information that meet required precision), then carry out according to step 203～204 of above-mentioned flow process;
Timer T1 is overtime; But if UE obtains useful positions information (like the positional information of recent record through GNSS location or other locate modes; Perhaps recent write down and positional information that meet required precision), then UE can carry this useful positions information in the MDT measurement report; Otherwise, report information such as RFfingerprint.
Timer T1 is overtime, and UE locatees through GNSS or other locate modes obtain useful positions information, and then UE reports RF fingerprint information.
In the above flow process, can judge in the following manner whether positional information meets required precision: define the band of position or scope according to positional information, reach a conclusion thereby parameter and the parameter preset thresholding that will be used to characterize this zone or range accuracy compare.Such as, can the band of position or scope that positional information defined is regular for circular, judge that whether this circular radius surpasses setting threshold (like 50m), then do not show that precision meets the requirements if surpass, otherwise precision is undesirable.
Can find out through above description; Subscriber equipment this locating information of storage and opening timing device after obtaining the LCS locating information that immediate MDT measures have been disposed; When immediate MDT measures generation; Under the not overtime situation of this timer, confirm to measure corresponding position information of user equipment with MDT and report according to the LCS locating information.Thereby the position information of user equipment when having remedied MDT measurement in the prior art does not on the one hand comprise the blank of LCS positional information; On the other hand because UE because the needs that MDT measures and (or special) triggered location separately, has therefore improved the accuracy of position information of user equipment when MDT measures under the situation that does not increase the UE power consumption.On the one hand, carry out Accuracy Matching again, make the positional information that reports network side can reach certain required precision, thereby better foundation is provided for the freedom of network decision-making through location information.

Step 301 (is wanted to know the positional information of oneself) for a certain reason like the user, UE begins the LCS position fixing process, thereby obtains own current position information, and the LCS position fixing process can be through realizing with E-SMLC alternately.UE stores the LCS positioning result get off, and opening timing device T2, and the setting means of timer T2 can repeat no more at this with the setting means of timer T1 in the flow process shown in Figure 2.
Step 302, subsequently, UE receives the immediate MDT configuration information that E-UTRAN sends, and uses this configuration information and carries out the MDT measurement configuration, and start immediate MDT measurement.
Step 303～304, owing to satisfy periodicity or trigger conditions, UE need report the MDT measurement report, if this moment, UE recorded useful LCS positioning result, then in the MDT measurement report, carries this LCS positioning result and reports network side; If UE does not have useful LCS positioning result, then UE can report RF fingerprint information.Wherein, under the not overtime situation of timer T2, the LCS positioning result that UE write down can be considered to useful positioning result; Further, consider required precision, and positioning accuracy LCS positioning result not overtime at timer T2 meets under the situation of required precision, can the LCS positioning result that UE write down be regarded as useful positioning result.
Wherein, the various implementations of step 303～304, identical or close with corresponding steps implementation described in the embodiment one, repeat no more at this.

Under the not overtime situation of timer T3; UE records the LCS positioning result; But do not record the useful positions information that obtains through autonomous locate modes such as GNSS (like the positional information of recent record; Perhaps recent write down and positional information that meet required precision), then carry out according to the step 403 of above-mentioned flow process;
Timer T3 is overtime; But if UE obtains useful positions information (like the positional information of recent record through GNSS location or other locate modes; Perhaps recent write down and positional information that meet required precision), then UE can carry this useful positions information in the MDT measurement report; Otherwise, report information such as RFfingerprint.
Timer T3 is overtime, and UE locatees through GNSS or other locate modes obtain useful positions information, and then UE reports RF fingerprint information.
After step 404, UE get into connected state, give network side with the MDT reporting measuring result of record.
