Description

Neighbor cell reporting method and device, E-SMLC and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for reporting neighboring cells, an E-SMLC, and a terminal.
Background
In a mobile communication system, an OTDOA (Observed Time Difference of arrival) positioning method and procedure are provided in the 3GPP standard:
an E-SMLC (Enhanced Serving Mobile Location center) issues related information of a Serving Cell (i.e., a residential Cell or a Reference Cell) and a neighboring Cell (neighbor Cell) to a terminal, including Cell PCI (Physical Cell Identifier), Cell ID, carrier frequency, PRS (Positioning Reference signal) configuration, and the like. The relevant information of the service cell and the adjacent cell sent by the E-SMLC to the terminal is obtained through the following processes:
a) the E-SMLC transmits OTDOA information REQUEST information to the service base station and a plurality of surrounding adjacent stations according to the base station working parameter information, and REQUESTs the configuration information of the service cell and the adjacent cells.
b) The base station feeds back the configuration INFORMATION of the service cell and the adjacent cell to the E-SMLC through an OTDOA INFORMATION RESPONSE message.
2. The terminal performs PRS measurement on the serving cell and the neighboring cell and calculates RSTD (Reference Signal time difference).
3. And the terminal reports the RSTD measurement result to the E-SMLC.
And 4, calculating by the E-SMLC according to the RSTD to obtain the longitude and latitude information of the terminal.
In OTDOA positioning, a hyperbolic positioning principle is adopted, and a terminal needs to measure at least PRS time delays of two neighboring cells and a serving cell belonging to different sites and calculate a time difference RSTD, where the neighboring cells and the serving cell belong to different sites. If the terminal measures different RSTD values of different cells of the same station, the RSTD values cannot be used as a plurality of effective RSTD values for calculating the positioning accuracy.
The more accurate the adjacent cell issued by the E-SMLC is, the more accurate the RSTD measured by the terminal is, and the higher the positioning accuracy is. In general, the more non-co-sited cells the terminal measures, the higher the positioning accuracy. Therefore, the accuracy of issuing the adjacent cell by the E-SMLC plays an important role in improving the positioning precision.
However, the 3GPP standard does not specify which neighboring cells are fed back to the E-SMLC by the base station, nor does it specify how the E-SMLC selects the neighboring cells to be delivered to the terminal, and the selection of the neighboring cells by the base station and the E-SMLC depends on the implementation of the network manufacturer.
The adjacent cell selection schemes adopted by the network manufacturers at present mainly include the following two types:
1. and the base station reports the service cell of the terminal and all cells of surrounding adjacent stations and relevant information of the cells to the E-SMLC according to the work parameter information, and the E-SMLC randomly selects one cell and relevant information thereof from the three cells of each base station and sends the cell and relevant information to the terminal.
2. And configuring a fixed adjacent cell relation on the E-SMLC, and issuing the fixed adjacent cell for the terminal positioning of a certain service cell.
For both of the above two schemes, certain disadvantages exist, which are specifically as follows:
the existing scheme 1: the adjacent cell issued by the E-SMLC has randomness and may cover the real adjacent cell relation of the terminal, so that the terminal cannot perform effective adjacent cell measurement, and the OTDOA is invalid or the precision is reduced.
Existing scheme 2: because the adjacent cell relations of different positions of the cell are not fixed, but the adjacent cell relations of different users are different, and the E-SMLC needs to maintain a large number of adjacent cell relations and changes along with the change of network optimization.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a neighboring cell reporting method, which is applied to an enhanced mobile service location center E-SMLC, and includes:
step 11, receiving first neighboring cell information reported by a terminal; wherein the first neighbor information includes at least one of:
a cell global identifier (ECGI) of a neighboring cell;
physical cell identification PCI of the adjacent cell;
identifying the frequency point identifier EARFCN of the adjacent cell;
the signal strength of the neighbor.
The first neighbor cell information is used for assisting the E-SMLC to determine a positioning measurement neighbor cell.
Optionally, the first neighboring cell information reported by the terminal includes: and the terminal measures the information of at least one adjacent cell.
As an embodiment, in case the first neighbor information includes information of at least two neighbors,
and the information of the at least two adjacent cells is arranged according to the sequence of the signal intensity of the adjacent cells from high to low.
For example, before reporting the measured first neighbor information, the terminal ranks the neighbors according to the signal strength, may directly report the information of the plurality of neighbors according to the ranking, or may add the corresponding signal strength to the reported information of the neighbors.
As another embodiment, the first neighbor information includes: information of at least one adjacent cell of the terminal meeting preset conditions;
wherein the preset conditions include:
the difference between the signal strength and the signal strength of the serving cell of the terminal is less than or equal to a first threshold value; and/or the presence of a gas in the gas,
the signal strength is greater than or equal to a second threshold value; and/or the presence of a gas in the gas,
the signal strength is greater than or equal to the signal strength of the serving cell.
For example, before reporting the measured first neighboring cell information, the terminal performs preliminary screening on the neighboring cells, for example, only reports information of the neighboring cells of which the difference between the signal strength and the signal strength of the serving cell of the terminal is less than or equal to a first threshold; for another example, only reporting the information of the neighboring cell of which the signal strength is greater than or equal to the second threshold value; for another example, only the information of the neighboring cell whose signal strength is greater than or equal to that of the serving cell is reported.
Preferably, in the above embodiment of the present invention, the signal strength includes at least one of:
received Signal Strength indication rssi (received Signal Strength indicator);
reference Signal Received power (rsrp);
reference Signal Received quality, rsrq, (reference Signal Received quality).
Further, the method for reporting a neighboring cell provided by the above embodiment of the present invention further includes:
and receiving second adjacent cell information of the terminal, which is reported by the wireless network equipment, wherein the second adjacent cell information is used for assisting the E-SMLC to determine a positioning measurement adjacent cell.
The E-SMLC may determine the positioning measurement neighbor cell observing the time difference of arrival OTDOA according to the first neighbor cell information and the second neighbor cell information.
For example, the positioning measurement neighbor of the OTDOA is determined as follows: the first adjacent cell information and the second adjacent cell information both comprise adjacent cells; for another example, the determined positioning measurement neighboring cell of the OTDOA is: and the signal intensity in the second adjacent cell information is greater than the threshold value, and the adjacent cell is the same as the adjacent cell in the first adjacent cell information. The E-SMLC may customize a rule for determining information of the positioning measurement neighboring cell of the OTDOA, or determine the rule for determining information of the positioning measurement neighboring cell of the OTDOA by the base station or the terminal and notify the rule to the E-SMLC, which is not specifically limited herein.
In the embodiment of the invention, the service cell of the terminal can also report the information of the service cell of the terminal. For example, the E-SMLC sends OTDOA information request information to the serving base station and a plurality of neighboring stations around the serving base station according to the base station parameter information, requesting information of the serving cell and the neighboring cells; and the base station feeds back the information of the service cell and the second adjacent cell information of the terminal to the E-SMLC through the OTDOA information response message.
And the E-SMLC selects the optimal positioning adjacent cell as the positioning measurement adjacent cell of the OTDOA by combining the first adjacent cell information reported by the terminal and the second adjacent cell information in the OTDOA information response message received by the E-SMLC from the service base station side.
Further, the method further comprises:
and sending the information of the positioning measurement neighbor cell determined by the E-SMLC to the terminal.
In the embodiment of the invention, the E-SMLC sends the determined optimal positioning adjacent cell (through the information transmission of the positioning measurement adjacent cell) to the terminal, the terminal carries out PRS measurement on the positioning measurement adjacent cell and the service cell of the OTDOA, calculates the RSTD, and the terminal reports the RSTD measurement result to the E-SMLC; and E-SMLC calculates the latitude and longitude information of the terminal according to RSTD.
Further, in the foregoing embodiment of the present invention, before step 11, the method further includes:
sending a long term evolution positioning protocol (LPP) message to a terminal, wherein the LPP message is used for requesting the terminal to report the first neighboring cell information; the LPP message includes one of:
an LPP Request Location Information message (i.e., LPP Request Location Information);
an LPP Information Request message (i.e., OTDOA Request Information or LPP Request Information);
the LPP provides Assistance Data (i.e., LPP provider Assistance Data).
Accordingly, as one embodiment, step 11 comprises:
receiving first neighbor cell information of the terminal, which is obtained by measuring the terminal most recently to the LPP message received by the terminal, reported by the terminal; or receiving first neighbor cell information of the terminal, which is measured after the terminal receives the LPP message and reported by the terminal.
The first neighbor cell information is neighbor cell information obtained by measuring the terminal in a connected state or an idle state, and can be reported in at least two ways:
1. reporting neighbor cell information (namely first neighbor cell information) obtained by the terminal through the last measurement;
2. after receiving the positioning request message, measuring the neighboring cell relation once immediately, and reporting the neighboring cell information (namely the first neighboring cell information) obtained by measurement. The method can avoid the situation that the service cell does not meet the measurement starting threshold determined by the existing mobility management parameters and the terminal cannot perform measurement.
As another example, step 11 includes:
receiving first neighbor cell information reported by a terminal through an LPP message; the LPP message includes one of:
the LPP provides a Location Information message (i.e., LPP provider Location Information);
an LPP Information Response message (i.e., OTDOA Response Information or LPP Response Information);
the LPP requests Assistance Data (i.e., LPP Request Assistance Data).
In summary, in the above embodiments of the present invention, the terminal measures to obtain the first neighboring cell information and reports the first neighboring cell information to the E-SMLC, and the E-SMLC adaptively adjusts the positioning measurement neighboring cell of the OTDOA, and improves the accuracy of the positioning measurement neighboring cell, so that the measurement accuracy of the terminal RSTD is improved, and the positioning accuracy of the OTDOA is improved.

As an embodiment, in case the first neighbor information includes information of at least two neighbors,
and the information of the at least two adjacent cells is arranged according to the sequence of the signal intensity of the adjacent cells from high to low.
For example, before reporting the measured first neighbor information, the terminal ranks the neighbors according to the signal strength, may directly report the information of the plurality of neighbors according to the ranking, or may add the corresponding signal strength to the reported information of the neighbors.
As another embodiment, the first neighbor information includes: information of at least one adjacent cell of the terminal meeting preset conditions;
wherein the preset conditions include:

1. reporting neighbor cell information (namely first neighbor cell information) obtained by the terminal through the last measurement;
2. after receiving the positioning request message, measuring the neighboring cell relation once immediately, and reporting the neighboring cell information (namely the first neighboring cell information) obtained by measurement. The method can avoid the situation that the service cell does not meet the measurement starting threshold determined by the existing mobility management parameters and the terminal cannot perform measurement.
