Description
Technical Field
The embodiment of the application relates to the technical field of wireless communication, in particular to a method and a device for determining position information of terminal equipment and a storage medium.
Background
With the rapid development of wireless communication technology, Long Term Evolution (LTE) technology has gained more and more attention in the whole society, and services based on accurate location information of mobile terminals have been widely applied. Because the indoor and outdoor optimization means are greatly different, the network can be more accurately evaluated and optimized only by starting from user behaviors, and therefore, the position information of the terminal equipment of the user is very important.
In the prior art, there are two types of methods for determining location information of a terminal device:
in one mode, the network device determines a distance between the terminal device and the base station according to a Time Advance (TA), and then determines location information of the terminal device according to an Arrival angle of signal (AOA). However, the TA is not accurate due to the time delay, and the blocking of the building causes the signal to undergo reflection and refraction, which affects the accuracy of the AOA, thereby causing inaccurate positioning of the terminal equipment.
Alternatively, based on the Application (APP) of the terminal device, the base station may obtain the location information of the user by parsing the signaling of the user plane interface S1-U, however, most of the location information of the APP is encrypted, and the location information cannot be directly parsed by the network device.
In summary, a method for determining location information of a terminal device is needed to determine accurate location information of the terminal device.

Fig. 2 exemplarily shows a flowchart of a method for determining location information of a terminal device, which is applicable to the embodiment of the present application, and as shown in fig. 2, the method includes:
In the embodiment of the application, the network device receives information corresponding to a time included in a time period from an i-n time to an i + m time reported by the terminal device, wherein the information corresponding to one time includes an identifier of the network device connected to the terminal device at the time and signal quality information reported by the terminal device at the time, and the network device can determine whether the terminal device is located in an indoor area or an outdoor area at the i time according to the information corresponding to the time included in the time period from the i-n time to the i + m time, so that the position information of the terminal device within a certain time length can be determined according to the determined position information at the i time, and a basis is provided for subsequent network optimization.
In this embodiment of the present application, the identifier of the network device may be an identity identifier of the network device, or may refer to a cell identifier of a cell covered by the network device, for example, if the network device is a network device in an outdoor distribution system, such as a macro station, the identifier of the network device may be an identifier of the macro station, or may be an identifier of a cell that provides a main communication service for the terminal device in the cell covered by the macro station.
In the embodiment of the present application, the Signal quality information may be Reference Signal Receiving Power (RSRP).
Before step 201, the terminal device may Report a Measurement Report (MR) to the network device, where the MR may include an identifier of the terminal device, a time when the MR reports the Measurement Report to the network device each time, an identifier of the network device connected to the terminal device at the time, and signal quality information at the time. Optionally, the terminal device may report the test report periodically.
In step 201, in an optional implementation manner, the network device may determine, according to an identifier of a network device connected to the terminal device at a certain time, that the network device connected to the terminal device at the certain time belongs to a network device in an indoor distribution system or a network device in an outdoor distribution system.
In the step 202, there are various embodiments that may determine the location information of the terminal device at the ith time according to the information corresponding to the times included in the time period from the i-n th time to the i + m th time, such as optional embodiment a1, optional embodiment a2, optional embodiment a3, and optional embodiment a4 provided in the example of the present application.
In an optional implementation manner a1, the location information of the terminal device at the ith time may be directly determined according to the identifier of the network device connected to the terminal device at the ith time, and if the network device identified by the identifier of the network device belongs to a network device in an indoor distribution system, the location information of the terminal device at the ith time is an indoor area; if the network device identified by the identifier of the network device belongs to the network device in the outdoor distribution system, the location information of the terminal device at the moment is the outdoor area.
Alternative embodiment a2, the location information of the terminal device at the ith time may be determined according to an identifier of a network device that accounts for a larger percentage of identifiers of network devices connected to the terminal device at each time in a time period from the ith-nth time to the ith + mth time, for example, if there are 10 times in the time period from the ith-nth time to the ith + mth time, and a network device identified by an identifier of a network device connected to the terminal device at 8 of the times belongs to a network device in the indoor distribution system, the location information of the terminal device at the time is an indoor area.
Alternative embodiment a3 may be configured to infer location information of the terminal device at the ith time according to the identifier and the signal quality information, for example, the network device identified by the identifier of the network device connected to the terminal device from the ith-nth time to the ith time belongs to a network device in the outdoor distribution system, and the signal quality is in a relatively stable value range and the value range is relatively high, and from the (i + 1) th time, the signal quality is increasingly poor, and below the value range, the location information at the ith time may be determined to be an outdoor area. From the ith time, the position of the terminal device is switched from the outdoor area to the indoor area.
Optionally, a4, in step 202, if the network device identified by the identifier of the network device corresponding to each of all times included in the time period from the i-th time to the i-th time belongs to a network device in the indoor distribution system, it is determined that the terminal device is located in the indoor area at the i-th time.
For example, suppose that a terminal device reports a test report to a network device every 5 seconds, assuming that n is equal to 6, an ith time is 11: 30 min 00 s at 20/2017, an ith-nth time is 11: 29 min 30 s at 20/2017, 12/20, and a time period from the ith time to the ith time includes 7 times, and if a network device identified by an identifier of the network device corresponding to the 7 times belongs to a network device in an indoor distribution system, it may be determined that the terminal device is located in an indoor area at the ith time, that is, the terminal device is located in the indoor area at 11: 30 min 00 s at 20/2017.
Based on the above embodiment a4, the present embodiment also provides several embodiments for determining the location information of the terminal device at the ith time, such as the following optional embodiment b1 and optional embodiment b 2.
In an optional implementation b1, in another optional implementation, if at least one time exists in all the times included in the time period from the i-n th time to the i-th time, and the network device identified by the identifier of the network device corresponding to the time belongs to a network device in the outdoor distribution system, it may be directly determined that the location information at the i-th time is an outdoor area.
Optionally, in the embodiment b2, in the step 202, if at least one time exists in all the times included in the time periods from the i-n th time to the i-th time, and the network device identified by the identifier of the network device corresponding to the time belongs to the network device in the outdoor distribution system, the network device may determine the location information of the terminal device at the i-th time according to the signal quality information corresponding to the time included in the time periods from the i-k th time to the i + m-th time; wherein k is a positive integer.
Based on the above example, assuming that m is equal to 4, the i + m-th time is 30 minutes 20 seconds at 11 o' clock at 12 months 20 days 2017. From 11: 29: 30 seconds of 20 days 12/20 in 2017 to 11: 30: 00 seconds of 20 days 20/12 in 2017, if the network device identified by the identifier of the network device corresponding to at least one time belongs to the network devices in the outdoor distribution system, the signal quality information corresponding to the time in the time period from the (i-1) th time to the (i + 4) th time can be obtained; and determining the position information of the terminal equipment at the ith moment.
Based on the above embodiment b2, the present embodiment also provides several embodiments of determining the location information of the terminal device at the ith time, such as the following optional embodiment c1 and optional embodiment c 2.
Optional embodiment c1, in an optional embodiment, if the RSRP corresponding to the ith time is within a numerical range representing that the signal quality is relatively high, it is determined that the terminal device is located in the outdoor area at the ith time.
Optionally, embodiment c2, in step 202, if the difference between the RSRP corresponding to the ith time and the RSRP corresponding to each of the times included in the time period from the i-k time to the i-1 time is greater than the fading threshold, it is determined that the terminal device is located in the outdoor area at the ith time.
In an alternative embodiment, k may be 1 if the interval of the periodic reporting is relatively long, such as 5 seconds, and k may be 2 if the interval of the periodic reporting is relatively short, such as 3 seconds, that is, the duration of the time period between the i-k th time and the i-th time is relatively short, and k is equal to 1 as an example below.
In this embodiment, if the network device is installed outside the building, the fading value may refer to a difference between a signal quality received by the terminal device inside the building and a signal quality received outside the building, and the fading value may be caused by a through-wall loss of a signal. The fading threshold may be set according to the fading values, and may be an average of all the fading values or a minimum of all the fading values.
Based on the above example, assuming that the fading threshold is-6 dB, if the RSRP corresponding to the i-th time (20/12/20/11/30 min 00 s in 2017) is 120dB, the RSRP corresponding to the i-1 th time (11/20/11/29 min 55 s in 2017) is 125dB, the difference between the former and the latter is 120dB and 125dB which is-5 dB, and is greater than the fading threshold-6 dB, it is determined that the terminal device is located in the outdoor area at the i-th time (20/11/30 min 00 s in 2017).
In the embodiment of the application, from 29 minutes and 30 seconds at 11 point of 12/20/2017 to 30 minutes and 00 seconds at 11 point of 20/2017, if at least one network device identified by the identifier of the network device at the time belongs to a network device in an outdoor distribution system at the time of the 7 times, and the difference between the RSRP corresponding to the i-th time and the RSRP corresponding to the i-1-th time is smaller than a fading threshold, the terminal device is not taken by a user from outside the building to inside the building, and therefore, the network device determines that the terminal device is located in an outdoor area at the i-th time (11 point of 20/2017).
Based on the above embodiment c2, the present embodiment also provides several embodiments of determining the location information of the terminal device at the ith time, such as the following optional embodiment d1 and optional embodiment d 2.
Optionally, in step 202, if at least one time exists in the time period from the i-k time to the i-1 time, a difference between the RSRP corresponding to the i time and the RSRP corresponding to the time is not greater than the fading threshold; and: and if the difference value of the RSRP corresponding to each time in the time periods from the (i + 1) th time to the (i + m) th time and the RSRP corresponding to the (i-k) th time is not greater than the fading threshold, determining that the terminal equipment is located in the indoor area at the ith time.
Based on the above example, if the RSRP at the i-th time (12/20/11/2017, 30 min 00 sec) is 118dB, the RSRP at the i-1 th time (12/20/11/29 min 55 sec in 2017) is 125dB, the difference between the former and the latter is 118-, therefore, the network device determines that the terminal device is located in the indoor area at the i-th time (12/20/11/2017, 30 min 00 sec).
In the embodiment of the application, since the time from 29 minutes and 30 seconds at 11 o 'clock of 20 days 12 months and 20 months in 2017 to 30 minutes and 00 seconds at 11 o' clock of 20 days 12 months and 20 months in 2017, if the network device with the identifier of the network device corresponding to at least one of the 7 moments belongs to the network device in the outdoor distribution system, and the RSRP corresponding to the i-1 th time (20/12/20/11/2017, 29 min 55 sec) is taken as the starting point of signal fading, the difference value of the RSRP corresponding to the following i +4 th time and the RSRP corresponding to the i-1 th time is smaller than the fading threshold value and keeps smaller than the fading threshold value all the time, it can be regarded as a course of action in which the terminal device is brought from outside the building to inside the building by the user, therefore, the network device determines that the terminal device is located in the indoor area at the i-th time (12/20/11/2017, 30 min 00 sec).
Optionally, in step 202, if at least one time exists in the time period from the i-k time to the i-1 time, a difference between the RSRP corresponding to the i time and the RSRP corresponding to the time is not greater than the fading threshold; and: and if at least one moment exists in the moments included in the time period from the (i + 1) th moment to the (i + m) th moment, and the difference value between the RSRP corresponding to the moment and the RSRP corresponding to the (i-k) th moment is greater than the fading threshold, determining that the terminal equipment is located in the outdoor area at the ith moment.
Based on the above example, if the RSRP corresponding to the i-th time (12/20/11/2017, 30 min 00 sec) is 118dB, the RSRP corresponding to the i-1 th time (12/20/11/29 min 55 sec 2017), which is 118-7 dB and is not greater than the fading threshold value-6 dB, is 125dB, the difference between the former and the latter is 118-7 dB and is not greater than the fading threshold value-6 dB, and the RSRPs corresponding to each of the i +1 times (12/20/11/20 th 2017/20 th h) to the i +4 th times (20/11/20 th 2017/20 th) are 118, 119, 122 and 123, respectively, the differences between the RSRPs corresponding to these four times and the RSRP corresponding to the i-1 th time (11/29 min 55 sec 20/11/2017/20 th) are 125dB, 7dB, -6dB, -3dB and-2 dB, respectively, and there is a difference between the RSRP corresponding to the i-1 th time and the fading threshold value-6 dB, therefore, the network device determines that the terminal device is located in the outdoor area at the ith time (12, 20, 11, 2017, 30 min 00 sec).
In the embodiment of the application, from 29 minutes and 30 seconds at 11 point on 20 th day in 12 th and 20 th in 2017 to 11 points on 20 th day in 12 th and 20 th in 2017 and 30 minutes and 00 seconds at 11 point on 20 th day in 20 th in 12 th and 20 th in 2017, if at least one network device identified by the identifier of the network device at the time in the 7 times belongs to a network device in an outdoor distribution system, and RSRP corresponding to the i-1 th time (11 points on 20 th and 20 th in 2017 th and 29 minutes and 55 seconds) is taken as a starting point of signal fading, although the difference between RSRP corresponding to the i-1 th time and RSRP corresponding to the i-1 st time is not greater than a fading threshold, at least one difference between RSRP corresponding to the i +1 th time and RSRP corresponding to the i +4 th time and RSRP corresponding to the i-1 st time is greater than the fading threshold and does not always stably maintain a state of not being greater than the fading threshold, the terminal device can be regarded as a shelter or, the RSRP is subjected to certain loss, and the signal consumption is reduced after a user walks out of a shelter or a corner area outside a building. Therefore, the network device determines that the terminal device is located in the outdoor area at the ith time (12, 20, 11, 2017, 30 min 00 sec).
Fig. 3 exemplarily shows a flowchart of a method for determining location information of a terminal device, which is applicable to the embodiment of the present application, and as shown in fig. 3, the method includes:
