Description

Mobile terminal positioning measurement processing method and device

technical field

Embodiments of the present invention relate to terminal positioning technology, and in particular, to a mobile terminal positioning measurement processing method and device.

Background technique

The positioning technology is a technology adopted to determine the geographical location of the terminal, and the resource of the wireless communication network can be used to directly or indirectly obtain the location information of the terminal. The standard terminal positioning methods adopted in the Long Term Evolution (LTE for short) include: network-assisted global navigation satellite system (Global Navigation Satellite System, GNSS for short) positioning, downlink positioning such as observed time difference of arrival (ObservedTime Difference of Arrival) , referred to as OTDOA) positioning method, uplink time difference of arrival (Uplink Time Difference of Arrival, referred to as UTDOA) positioning method, etc.

In LTE, the implementation principle of the OTDOA positioning method is as follows. After the network side positioning server specifies the sending and receiving configuration of Positioning Reference Signal (PRS) for the base station and the terminal, the base station sends the PRS downlink. The terminal receives PRSs from multiple base stations, and identifies the first path of arrival position of each PRS, and can obtain the PRS arrival time difference between different base stations (that is, the reference signal time difference (reference signal time difference, RSTD for short)), and Report to the positioning server. The positioning server receives the difference in arrival time of reference signals from different base stations through the terminal, which can be mapped into the distance difference between the terminal and different base stations. Through the mathematical calculation of the hyperbolic model, the positioning server can obtain the accurate position of the terminal.

In the existing OTDOA, the terminal needs to perform RSTD measurement for PRS from different base stations. If the current operating frequency point or carrier of the terminal is inconsistent with the carrier of the PRS, when the terminal needs to measure the PRS on this carrier, it needs to use the terminal's The RF chain is tuned. Figure 1 is a schematic diagram of radio frequency chain adjustment during positioning measurement in the prior art. As shown in Figure 1, the terminal has only one radio frequency chain. When the terminal performs measurement on frequency band 1, the center frequency point of the radio frequency chain is at the center frequency point of frequency band 1. 1, the radio frequency chain covers frequency band 1. When the terminal needs to measure the PRS signals of frequency band 1 and frequency band 2 at the same time, it is necessary to adjust the center frequency point of the terminal radio frequency chain from center frequency point 1 to center frequency point 2, and set the radio frequency The chain is tuned to fully cover Band 1 and Band 2. If the positioning measurement is a measurement behavior independent of the mobility measurement, this will cause a double interruption. For example, as shown in Figure 1, after the terminal positioning measurement is completed, the radio frequency chain will be adjusted back to the center frequency point of frequency band 1. If At this time, the terminal needs to perform the mobility measurement of the frequency band 2 again, and the radio frequency chain will be adjusted again, causing a second interruption.

Multiple adjustments to the radio frequency chain in the prior art will interrupt the current operating frequency point of the mobile terminal or services on the carrier, and cause a decrease in throughput.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 2 is a flow chart of Embodiment 1 of the mobile terminal positioning measurement processing method of the present invention. The execution subject of this embodiment is a mobile terminal positioning measurement processing device, which can be implemented by software and/or hardware. As shown in FIG. 2, the mobile terminal positioning measurement processing method of this embodiment may include:

Step 201: Receive measurement status information of the mobile terminal, where the measurement status information includes the measurement carrier and/or measurement frequency point currently used by the mobile terminal.

The executor of this embodiment may be a mobile terminal positioning measurement processing device configured on a positioning server, or may be a positioning server. The solution of this embodiment may be applied to an OTDOA positioning method of LTE.

For example, the positioning server receives the measurement status information of the mobile terminal, and the measurement status information may include the measurement carrier and/or measurement frequency point currently used by the mobile terminal. Before that, the positioning server may also initiate a request to the base station or the mobile terminal to obtain The measurement status information of the mobile terminal, the measurement status information and the acquisition request of the measurement status information may be sent through LTE Positioning Protocol A (LTE Positioning Protocol A, LPPa for short) signaling.

Step 202: Select a plurality of target base stations for sending positioning reference signals for the mobile terminal according to the measurement state information, and the target base stations are base stations sending positioning reference signals using the measurement carrier and/or measurement frequency currently used by the mobile terminal.

For example, the positioning server knows the measurement carrier and/or measurement frequency points f0, f1, and f2 currently used by the mobile terminal according to the measurement status information, and the positioning server will preferentially select the current measurement carrier and/or measurement frequency points f0, f1, and f2. Base stations are used as target base stations, and the mobile terminal measures the positioning reference signals sent by each target base station. At this time, the radio frequency chain of the mobile terminal covers f0, f1 and f2, which will not cause adjustment to the radio frequency chain of the mobile terminal, and will not cause interruption of data transmission on the currently used measurement carrier and/or measurement frequency point.

Step 203 , sending the positioning measurement assistance information of each selected target base station to the mobile terminal, so that the mobile terminal can measure the positioning reference signal sent by each target base station.

For example, the positioning server sends the positioning measurement assistance information of each selected target base station to the mobile terminal, and the positioning measurement assistance information may include at least one of the following: Physical Cell Identifier (PCI for short), measurement frequency point, PRS time The domain offset and the timing of the target base station are used for the mobile terminal to measure the positioning reference signal sent by each target base station.

The positioning measurement assistance information may be sent by, for example, LTE Positioning Protocol (LPP for short) signaling.

In this embodiment, by receiving the measurement status information of the mobile terminal, the measurement status information includes the measurement carrier and/or measurement frequency point currently used by the mobile terminal, and select multiple transmission locations for the mobile terminal according to the measurement status information a target base station of the reference signal, the target base station is a base station that transmits a positioning reference signal using the measurement carrier and/or measurement frequency point currently used by the mobile terminal, and sends the positioning measurement assistance information of each selected target base station to the mobile terminal, For the mobile terminal to measure the positioning reference signal sent by each target base station, since each selected target base station is a base station that sends the positioning reference signal using the measurement carrier and/or measurement frequency point currently used by the mobile terminal, the mobile terminal can be at Measurements are performed on the currently used measurement carrier and/or measurement frequency point, without adjustment to other measurement carriers and/or measurement frequency points for measurement, avoiding multiple adjustments to the radio frequency chain, and realizing the measurement carrier currently used by the mobile terminal And/or the service on the measurement frequency point continues, thereby improving the throughput.

The technical solution of the method embodiment shown in FIG. 1 will be described in detail below using several specific embodiments.

In Embodiment 2 of the mobile terminal positioning measurement processing method of the present invention, on the basis of the method embodiment shown in FIG. 1 , the measurement status information may further include:

Preferably, in this embodiment, the selection of multiple target base stations for sending positioning reference signals for the mobile terminal according to the measurement state information may also include at least one of the following situations:

First case:

If it is known from the radio frequency capability information that the mobile terminal supports only one radio frequency chain, the selected target base station is the base station that sends the positioning reference signal using the measurement carrier and/or measurement frequency currently used by the mobile terminal.

For example, the positioning server knows that the mobile terminal only supports one radio frequency chain according to the radio frequency capability information, and knows that the current radio frequency chain covers the currently used measurement frequency point according to the measurement carrier and/or measurement frequency point currently used by the mobile terminal, so the positioning server The base station that sends the PRS at the frequency point among the currently used measurement frequency points will be preferentially selected as the target base station, so that the mobile terminal can measure the PRS sent by each target base station. Another example is that the measurement frequency points currently used by the mobile terminal are located in frequency band 1 and frequency band 2. Currently, the mobile terminal only supports one radio frequency chain, so the positioning server will preferentially select the base stations that send PRS on the frequency points on frequency band 1 and frequency band 2. as the target base station. The positioning server sends the positioning measurement auxiliary information of the selected target base stations to the mobile terminal, and the mobile terminal measures the PRS sent by each target base station, so that the data transmission on the original frequency point will not be interrupted.

Second case:

If it is known from the radio frequency capability information that the mobile terminal supports two radio frequency chains, and it is known from the idle state of the current radio frequency chain that one of the radio frequency chains is in an idle state, then the selected target base station is the The measurement carrier and/or measurement frequency point currently used by the terminal, and the base station that sends the positioning reference signal using another measurement carrier and/or measurement frequency point.

For example, according to the measurement carrier and/or measurement frequency point currently used by the mobile terminal, it is learned that the current radio frequency chain covers the currently used measurement frequency point, and the frequency band currently used by the mobile terminal is only frequency band 1 where the currently used measurement frequency point is located, but the current mobile terminal Two radio frequency chains are supported, that is to say, one radio frequency chain is idle, so the positioning server will preferentially select the base station that sends PRS on frequency band 1 and any other frequency band except frequency band 1 as the target base station, so that the mobile terminal The PRS sent by each target base station is measured. Another example is that the measurement frequency point currently used by the mobile terminal has frequency band 1 and frequency band 2. The current mobile terminal supports two radio frequency chains. If the current mobile terminal only uses one radio frequency chain to receive or transmit or measure frequency band 1 and frequency band 2 If the signal on the other radio frequency chain is idle, the positioning server can select the base station to send PRS at frequency points on frequency bands 1 and 2 and any other frequency band except frequency band 1 and 2 according to the idle information of this radio frequency chain As the target base station, the mobile terminal measures the PRS sent by each target base station.

The third case:

If it is known from the radio frequency capability information that the mobile terminal supports two radio frequency chains, and it is known from the idle state of the current radio frequency chain that one of the radio frequency chains is in an idle state, then the selected target base station is the The measurement carrier and/or measurement frequency currently used by the terminal is the base station that sends the positioning reference signal.

For example, according to the measurement carrier and/or measurement frequency point currently used by the mobile terminal, it is learned that the current radio frequency chain covers the currently used measurement frequency point, and the frequency band currently used by the mobile terminal is only frequency band 1 where the currently used measurement frequency point is located, but the current mobile terminal Two radio frequency chains are supported, that is to say, one radio frequency chain is idle, so the positioning server can preferentially select the base station that sends PRS at the frequency point on frequency band 1 as the target base station, so that the mobile terminal can measure the PRS sent by each target base station. Another example is that the measurement frequency point currently used by the mobile terminal has frequency band 1 and frequency band 2. The current mobile terminal supports two radio frequency chains. If the current mobile terminal only uses one radio frequency chain to receive or transmit or measure frequency band 1 and frequency band 2 If the signal on the other radio frequency chain is idle, the positioning server can select the base station that sends the PRS at the frequency points on frequency bands 1 and 2 as the target base station according to the idle information of this radio frequency chain, so that the mobile terminal can detect each target The PRS sent by the base station is used for measurement.

Fourth case:

If it is known from the radio frequency capability information that the mobile terminal supports two radio frequency chains, and it is known from the idle state of the current radio frequency chain that one of the radio frequency chains is in an idle state, then the selected target base station is an application other than the mobile terminal A base station that transmits a positioning reference signal at a measurement carrier and/or measurement frequency point other than the currently used measurement carrier and/or measurement frequency point.

For example, according to the measurement carrier and/or measurement frequency point currently used by the mobile terminal, it is learned that the current radio frequency chain covers the currently used measurement frequency point, and the frequency band currently used by the mobile terminal is only frequency band 1 where the currently used measurement frequency point is located, but the current mobile terminal Two radio frequency chains are supported, that is to say, one radio frequency chain is idle, so the positioning server can preferentially select the base station that sends the PRS on any frequency point except frequency band 1 as the target base station, so that the mobile terminal can detect each target base station Sent PRS for measurement. Another example is that the measurement frequency point currently used by the mobile terminal has frequency band 1 and frequency band 2. The current mobile terminal supports two radio frequency chains. If the current mobile terminal only uses one radio frequency chain to receive or transmit or measure frequency band 1 and frequency band 2 If the signal on the other radio frequency chain is idle, the positioning server can select the base station that sends the PRS at any frequency point except frequency bands 1 and 2 as the target base station according to the idle information of this radio frequency chain, so that the mobile The terminal measures the PRS sent by each target base station.

Fifth case:

If it is known from the radio frequency capability information that the mobile terminal supports two radio frequency chains, and it is known from the idle state of the current radio frequency chain that none of the radio frequency chains is in an idle state, then the selected target base station is for applying the mobile The measurement carrier and/or measurement frequency currently used by the terminal is the base station that sends the positioning reference signal.

For example, the mobile terminal currently uses frequency band 1 and frequency band 2, and the current mobile terminal supports two radio frequency chains. If frequency band 1 has already used a radio frequency chain, and frequency band 2 has also used a radio The status is non-idle, and the positioning server can select the base station that sends PRS at the frequency points on frequency band 1 and frequency band 2 as the target base station according to the information of the non-idle state of the radio frequency chain, so that the mobile terminal performs PRS transmission on each target base station. Measurement.

Preferably, in this embodiment, the measurement state information may further include: timing of mobility measurement and/or measured radio access technology (Radio Access Technology, RAT for short);

The timing of the mobility measurement is used to preferentially select a base station consistent with the timing of the mobility measurement as a target base station;

The RAT is used to preferentially select a base station of the same RAT as the target base station.

The positioning server will preferentially select the base stations in the above target base stations whose timing is consistent with the mobile terminal, and the positioning server will also preferentially select the base stations in the above target base stations consistent with the RAT supported by the mobile terminal.

In this embodiment, according to the radio frequency capability information of the mobile terminal and/or the idle state of the current radio frequency chain and/or the timing of the mobility measurement and/or the measured RAT, multiple more suitable ones for transmitting positioning reference signals are selected for the mobile terminal. The target base station avoids multiple adjustments to the radio frequency chain, and realizes the continuous operation of the service on the measurement carrier and/or measurement frequency point currently used by the mobile terminal, thereby improving the throughput.
