Description

Evolution base station, cell switching and E-CID positioning method and device thereof

Technical field

The present invention relates to the field of Long Term Evolution (LTE) network positioning service systems, and in particular, to an Evolved NodeB (eNB) and its cell handover and enhanced cell identifier (E-CID) positioning method and apparatus.

Background technique

The positioning service is an important value-added service in the LTE network, which refers to obtaining the location information (such as latitude and longitude) of the mobile terminal through the wireless positioning technology, and providing the location information to the mobile terminal itself, the mobile communication network or other external entities. Used to implement a variety of location-related services.

The positioning service is implemented in the LTE network, and the LTE Positioning Protocol (LPP) and the LTE Positioning Protocol Annex (LPPa) are used. The initiator of the positioning request may be a terminal, a network, or a third-party entity. .

At present, the positioning methods supported in the LTE network are: A-GNSS (Assisted Global Navigation Satellite System) positioning method, Observed Time Difference Of Arrival (OTDOA) positioning method and E- CID positioning method.

The E-CID positioning method is an enhancement to the cell identification (CID, Cell-ID) positioning method. The principle of the CID positioning method is that the location of the User Equipment (UE) can be estimated using the geographic coordinates and CID information of the eNB served by the UE. The information of the eNB and the cell can be obtained by methods such as paging, tracking domain update, and the like. The E-CID positioning technique uses information of other UEs other than itself or measurements of related radio resources in the network to improve the accuracy of its own UE location estimation.

The E-CID positioning process is divided into uplink E-CID positioning and downlink E-CID positioning. In this paper, only the uplink E-CID positioning process is discussed. Therefore, if there is no special explanation, the following E-CID positioning That is, the uplink E-CID positioning.

For E-CID positioning, it is divided into one-time and periodic positioning. For one-time E-CID positioning, the eNB uses the measurement result required for positioning at one time through the Mobility Management Entity (MME). It is sent to the Enhanced Serving Mobile Location Centre (E-SMLC), and the E-SMLC calculates the latitude and longitude information of the UE according to the received measurement result. For periodic E-CID positioning, the measurement results required for positioning are reported to the E-SMLC periodically. During the reporting of the measurement results, multiple exchanges of information will occur between the UE, the eNB, and the E-SMLC. Once the UE is in the process. The cell handover is performed. Since the target eNB cannot receive the E-SMLC identification information of the source eNB, the E-CID positioning is interrupted. The interruption of the positioning service will seriously affect the user experience. For the UE to provide positioning services when the cell handover occurs, the current LTE positioning protocol does not provide a solution.

detailed description

FIG. 1 is a schematic flowchart of a conventional periodic E-CID positioning method. As shown in FIG. 1, the method includes the following steps:

Step 1: The UE sends a location service request to the E-SMLC through the MME, and the positioning service interaction process is completed between the UE and the E-SMLC.

Step 2: The E-SMLC sends an E-CID measurement request to the eNB, where the measurement request includes an E-CID Positioning indicator and E-CID positioning measurement vector;

The E-CID positioning identifier may include: a message type, an LPPa Transaction ID, and an E-SMLC Measurement ID; and the E-CID positioning measurement vector may include: Reference Signal Received Power (RSRP), and reference signal receiving quality. (Reference Signal Received Quality, RSRQ), time difference (Rx-Tx) and angle of arrival (AOA) of the UE and the eNB;

Step 3: The eNB returns an E-CID measurement response to the E-SMLC through the MME.

Step 4: The eNB sends a measurement configuration of the E-CID to the UE, and measures a vector that the eNB needs to measure.

Here, it may be that the Rx-Tx and the AOA of the eNB are measured;

Step 5: The UE performs measurement according to the vector that the UE needs to measure in the measurement configuration, and periodically reports the measurement result according to the time required in the measurement configuration.

The vector that needs to be measured by the UE includes: RSRP, RSRQ, and Rx-Tx of the UE.

Step 6: The eNB combines the reported vector measurement result of the UE with the vector measurement result measured by the eNB to form a positioning measurement report, and reports the report to the E-SMLC through the Lppa message. The E-SMLC calculates the location of the UE according to the positioning measurement report. ;

Step 7: The E-SMLC sends a location service response to the UE by using the MME, where the location service response includes location information of the UE.

It can be seen from the above process that if the UE performs cell handover after completing step 1, and the E-SMLC sends an E-CID measurement request to the source eNB, the target eNB will not receive the E-CID measurement request in step 2. The information contained so that the E-CID measurement report can no longer be reported to the E-SMLC.

Here, the E-CID measurement configuration is independent of the measurement configuration sent by the target eNB to the UE in the general cell handover process, and is a measurement configuration that is specifically sent for the E-CID location service;

Step H: The UE periodically reports the measurement result of the positioning measurement vector measured by the UE to the target eNB according to the E-CID measurement configuration.

In step I, the target eNB combines the measurement result of the positioning measurement vector periodically reported by the UE and the vector result measured by the UE to form an E-CID measurement report, which is periodically reported to the E-SMLC; and the E-SMLC reports according to the positioning measurement report. The location of the UE is calculated;

Step J: The target eNB sends an E-CID measurement configuration information release request to the source eNB; the source eNB releases the configuration resource of the measurement vector of the UE;

Step K: The E-SMLC sends a location service response to the UE by using the MME.

Step 301: When performing cell handover for the UE, determine whether the UE is performing periodic E-CID positioning. When it is determined that the UE is performing periodic E-CID positioning, the E-SMLC receives the E- sent by the MME. a CID measurement request, where the E-CID measurement request includes configuration information of an E-CID positioning identifier and a positioning measurement vector;

Specifically, after the source eNB receives the measurement report reported by the UE, the source eNB determines that the UE performs cell handover according to the measurement report, and the process is the same as the prior art, and details are not described herein again;

The source eNB further determines whether the UE is performing periodic E-CID positioning, and the specific determining method is: the source eNB checks whether the E-SMLC is received to send an E-CID measurement request to the source eNB; and when the source eNB receives the E-SMLC transmission.

Further, the target eNB sends an E-CID measurement vector configuration request to the source eNB to obtain configuration information of the E-CID positioning measurement vector of the UE saved by the source eNB, where the E-CID measurement vector configuration request includes The configuration parameters provided by the eNB in the locating service, therefore, the cell switching method in FIG. 3 further includes:

Receiving an E-CID measurement vector configuration request sent by the target eNB;

Specifically, the source eNB receives the E-CID measurement vector configuration request sent by the target eNB, and returns an E-CID measurement configuration response to the target eNB according to the saved configuration information of the E-CID positioning measurement vector of the UE.

Here, the E-CID measurement vector configuration request includes a set of E-CID positioning measurement vectors that the target eNB needs to acquire; and the E-CID measurement configuration response includes a configuration in which the E-CID positioning measurement vector set is saved in the source eNB. information.

Specifically, after receiving the E-CID measurement configuration information release request sent by the target eNB, the source eNB releases the configuration information of the E-CID positioning measurement vector of the UE, that is, releases the storage space for storing the configuration information.

Using the cell handover method of the source eNB provided by the foregoing embodiment, the source eNB sends the handover request carrying the E-CID location identifier to the target eNB, so that the target eNB can obtain the E-CID location identifier necessary for the location service. The source eNB sends the measurement vector configuration information required for the positioning to the target eNB by responding to the E-CID measurement vector configuration request, so that the target eNB can The measurement vector value required for the location service is obtained; thereby providing a basis for ensuring that the positioning service is not interrupted during the cell handover process.

Step 401: After receiving the handover request about the UE sent by the source eNB, determining whether the handover request carries the E-CID location identifier;

Specifically, after receiving the handover request about the UE sent by the source eNB, the target eNB completes the subsequent process of the UE cell handover in response to the handover request, and determines whether the E-CID location identifier is carried in the handover request.

When the handover request carries the E-CID positioning identifier, perform the following steps:

Step 402: Send an E-CID measurement vector query to the E-SMLC through the MME according to the E-CID positioning identifier.

Specifically, the target eNB sends an E-CID measurement vector query to the E-SMLC according to the E-CID positioning identifier according to the Lppa protocol; where the positioning measurement vector in the E-CID measurement vector query may include: TA Type1, TA Type2, AOA, RSPR and RSRQ, Cell-Id.

Step 403: Receive an E-CID measurement vector result returned by the E-SMLC through the MME.
