Background technique

Book

The location service (LCS) is a service that provides positioning capabilities for user equipment (UE, User Equipment). The methods for positioning include: a method based on the IDentity, a method based on triangulation, and a GPS-based ( Global Posiiionmg System, global positioning system, etc. The private base station (HNB, Home Node B) and the private evolved base station (HeNB), when installed and configured, the operator must be able to obtain the geographical location information of the HNB/HeNB, and when the HNB and the HeNB initiate an emergency call. It is necessary to provide UE positioning information with sufficient accuracy. The following describes the relationship between the HNB/HeNB and the Close Subscribers Group (CSG) and the CSG cell: Each HNB/HeNB has a unique identifier, that is, the HNB ID, which is configured by the administrator of the HNB. The UE can display the HNB ID to the user by reading the broadcast information of the HeNB; all HeNBs belonging to the same CSG share one CSG ID; one HNB/HeNB can provide one or more cells, called CSG cells; In the case, all CSGs that the UE is allowed to access are saved in a list. The coverage of the CSG cell will be much smaller than the coverage of the normal macro cell, such as the coverage of ten to several tens of meters. Moreover, the geographical location of the CSG cell is recorded on the network side, that is, for a normally operating CSG network, the network side can know the specific location of the CSG cell. Based on this, once the UE initiates a service in a CSG cell, The network side will be able to know its location information and be more accurate than the geographical location information of the macro cell.

In the existing cell ID-based positioning method, although the UE can obtain higher positioning accuracy in the HNB and the He B, not all UEs can access the CSG cell; when the UE is in a non-CSG cell, such as a macro cell , can not take advantage of the positioning advantages of CSG cells.

Specifically, the UE acquires information about the surrounding private cell by receiving a system signal or other signal of the surrounding private cell. The information may include information such as a cell identifier ID, a tracking area identifier TA ID, a CSG ID, and an HNB ID of the private cell. The information helps the network side determine the location of the private cell, and then learns the location of the UE.

In the embodiment of the present invention, optionally, the UE requests the eNB to allocate measurement interval (GAP) information or discontinuous reception mechanism (DRX) information to support the positioning measurement. During the time interval indicated by the GAP information, the UE only measures the surrounding private cell identity and does not process other services; the DRX indicates that the UE is in a resting state and the awake state periodically alternates. When in the rest state, the UE does not accept the data of the cell. Other private cells can be measured and cell information can be obtained.

In addition to obtaining the PCL TA ID, the CSG ID, and the HNB ID, the UE may also acquire the transmit power of the private cell, so as to know the coverage of the private cell.

S305. The UE reports a measurement report to the eNB. The measurement report mainly includes an identifier of a surrounding private cell, and the identifier may be one or more of a PCI, a TA ID, a CSG ID, an HNB ID, or a cell ID. The reported measurement report may also include the transmit power information of the cell, or the coverage information.

S306. The eNB sends a measurement report reported by the UE to the MME. Specifically, the eNB sends a measurement report carrying the private cell information around the UE to the MME, where the cell information includes, but is not limited to, a PCI, a TA ID, CSG ID, HNB ID, Cell ID, Cell Transmit Power or Cell Coverage. Of course, the geographic location of the private cell may also be determined according to the identification information of the private cell, and the geographic location information is added to the measurement report.

S307. After receiving the measurement report sent by the eNB, the MME sends the measurement report to the GMLC. In the embodiment of the present invention, the positioning center and the UE exchange information through the intermediate wireless network, and the positioning center instructs the UE to report the measurement report after measuring the surrounding private cell system signal by using the indication information carried in the positioning measurement request, and the positioning measurement is performed. The request also carries some parameters to speed up the measurement of the UE.
