Detailed description of the invention
Fig. 1 is the schematic flow sheet of existing a kind of periodicity E-CID localization method, as it is shown in figure 1, the method comprises the following steps:
Step 1, UE sends request for location services by MME to E-SMLC, completes positioning service interaction between UE and E-SMLC;
Step 2, E-SMLC sends E-CID to eNB and measures request, comprises E-CID positioning mark and vector is measured in E-CID location in this measurement request;
Wherein, E-CID positioning mark comprises the steps that type of message, LPPaTransactionID, E-SMLCMeasurementID; Measure vector with E-CID location and comprise the steps that Reference Signal Received Power (ReferenceSignalReceivedPower, RSRP), Reference Signal Received Quality (ReferenceSignalReceivedQuality, RSRQ), UE and eNB receiving and transmitting signal time difference (Rx-Tx) and arrive angle (AOA);
Step 3, eNB returns E-CID by MME to E-SMLC and measures response;
Step 4, eNB issues the measurement configuration of E-CID to UE, and measures the required vector measured of eNB;
Here it is possible to be Rx-Tx and the AOA measuring eNB;
Step 5, UE is according to measuring the vector measurement needing UE to measure in configuration; And according to measuring the time required in configuration, periodic report measurement results;
Wherein it is desired to UE measure vector include: RSRP, RSRQ and UE Rx-Tx.
Step 6, eNB merges the vector measurement result reported of UE and the vector measurement result of eNB self measurement, forms location measurement report, is reported to E-SMLC by Lppa message; The position of UE, according to this location measurement report, is calculated by E-SMLC;
Step 7, E-SMLC sends positioning service response by MME to UE, comprises the positional information of UE in this positioning service response.
From said process, if UE is after completing step 1, carries out community switching, and the E-CID request of measuring also has been sent to source eNB by E-SMLC, then target eNB will be unable to receive the information that in step 2, the E-CID request of measuring comprises, thus E-CID measurement report cannot be reported to E-SMLC again.
For solving this problem, the cell switch process of UE is merged by the embodiment of the present invention with periodically E-CID position fixing process so that even if there is community switching, still can ensure that E-CID location is not interrupted.
In order to be illustrated more clearly that the embodiment of the present invention and technical scheme, below in conjunction with drawings and Examples, technical scheme is described in detail, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiment.
