Embodiment
Basic thought of the present invention is: base station is exclusively used in the position reference symbol of user terminal location, network side is notified to UE by positioning assistance data with the information of the position reference symbol of base station, when UE receives positioning assistance data, can measure according to the position reference symbol that is obtained, because the transmitting power of position reference symbol is higher than the transmitting power and the different frequency with described data transfer signal of data transfer signal, therefore, the signal of UE current service cell is very little to the interference of position reference symbol, UE can accurately measure the position reference symbol of adjacent area, the measurement result that obtains is also more accurate, thereby promoted the accuracy of UE location, improved location quality of service.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the flow chart of the sending method of positioning assistance data of the present invention, and as shown in Figure 1, the sending method of positioning assistance data of the present invention may further comprise the steps:
Step 101: when network need obtain the positional information of certain user terminal (such as in urgent call, network need position user terminal present located position), send Location Request to this user terminal by network entity SMLC, the positioning assistance data that accessory terminal is positioned sends to this user terminal simultaneously.Because user terminal needs according to signal of base station is measured the time of advent, thereby the time of advent of signal is poor between calculation base station, thereby calculate the residing position of user terminal, so network need be indicated the tabulation of the base station that needs its signal of measurement in positioning assistance data.The information that should comprise reference base station (serving BS that user terminal is current) in the tabulation perhaps, comprises reference base station and other information for the candidate base station of measuring (the adjacent base station of reference base station).Comprise at least a of following information in each base station information: the parameter of the position reference symbol that geographical location information, network side disposed of the sign of base station, the timing information of base station, base station.Positioning assistance data structure of the present invention is as shown in table 1:
Table 1
Wherein, the concrete structure of the reference base station information in the table 1 and the item of information that comprises are as shown in table 2:
Table 2
Base Station Identification in the table 2 comprises the cell physical address (PCI of sub-district under physical layer identifications such as the base station, PhysicalCell Identity), also can be the overall identification such as the Cell Global Identity (CGI of sub-district under the base station, CellGlobalIdentifier), can realize sign by above-mentioned cell ID to the base station.Wherein, the concrete structure of the candidate base station information in the table 1 and the item of information that comprises are as shown in table 3:
Table 3
