Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with aspects of the present disclosure.
Before introducing the signal strength detection method, device, electronic equipment and storage medium shown in the disclosure, an application scenario related to an embodiment of the disclosure is first described.
In 5G NTN planning, a terminal needs to perform measurement and reselection between a satellite communication network and a terrestrial cellular network in order to preferentially use the cellular network when there is the terrestrial cellular network, as shown in fig. 1, a is a satellite, B is a base station of the cellular network, and a dotted line area is a divided area of the cellular network. However, if the terminal is always performing measurements of the cellular network, long-time ineffective measurements may be caused in some places where the cellular network is not available, and the terminal resources are wasted.
In the discussion of 3GPP (english: 3rd Generation Partnership Project, chinese: third generation partnership project) RAN2 it is proposed to limit the measurement of the cellular network by the terminal by delimiting specific areas. The network may broadcast location information for a particular area to the terminal, where the terminal may make measurements on the cellular network, may not make measurements on the cellular network outside the particular area, or may make low priority measurements. However, this division has a significant disadvantage, as shown in fig. 2, in that the area inside the ellipse C is the area covered by the cellular network, the area inside the circle D is a delimited specific area, and it is difficult for the given area of the network to be completely consistent with the coverage area of the cellular network, and in fact, it is impossible to be completely consistent due to the complexity of the coverage of the cellular network. In this way, in case of defining a strict measurement area, it is possible that the terminal may not measure the cellular network at certain locations of a specific area, such as area b in fig. 2; it is also possible that the cellular network may be measured at some location outside a specific area, but no measurement is made, such as area a in fig. 2.
Fig. 3 is a flowchart illustrating a method for detecting signal strength according to an exemplary embodiment, and the method may include the following steps, as shown in fig. 3, applied to a terminal.
In step 101, in response to the terminal entering the target area, a first signal transmission loss is determined based on the target reference position, the terminal position information of the terminal, and the signal transmission frequency. The target reference position is determined according to the position of the base station, and the signal transmission frequency is the signal transmission frequency of the target base station corresponding to the target reference position.
In step 102, a second signal transmission loss is determined based on the target reference position, the region position information of the target region, and the signal transmission frequency.
By way of example, a target area where a cellular network may be present may be predetermined, wherein the probability of the cellular network being present at any location within the target area is greater than 0 and less than 1. If the terminal enters the target area, it may be determined whether to detect the cellular network based on the probability that the cellular network exists at the current location of the terminal. In some embodiments, the target reference position may be obtained through a network, where the target reference position is determined according to a position of a base station, for example, a position where a certain base station near the terminal is located, or a position determined by positions of a plurality of base stations near the terminal, which is not specifically limited in this disclosure.
The closer the terminal is to the target reference position, the larger the probability of the existence of the cellular network, so that the first distance between the terminal and the target reference position can be obtained according to the target reference position and the terminal position information of the terminal, and then the first signal transmission loss is calculated according to the first distance and the signal transmission frequency of the target base station corresponding to the target reference position and is used as a detection probability threshold. The terminal position information indicates the current position of the terminal.
It should be noted that the target base station may be a base station for determining the target reference position, for example, when the target reference position is a position where a base station closest to the terminal is located, the target base station may be a base station closest to the terminal, and for example, when the target reference position is a position determined by positions of a plurality of base stations near the terminal, the target base station may be a plurality of base stations near the terminal. If the target base station is one and the base station has a plurality of signal transmission frequencies, or if the target base station is a plurality of and the plurality of target base stations includes a plurality of signal transmission frequencies, the lowest frequency of the plurality of signal transmission frequencies may be taken as the signal transmission frequency used to determine the signal transmission loss in the embodiments of the present disclosure. Wherein the signal transmission loss (including the first signal transmission loss and the second signal transmission loss) may be determined according to at least one of path loss, shadow fading, and multipath fading, and the manner of determining the signal transmission loss may be selected according to environmental information around the terminal.
In other embodiments, a second distance between the target position in the target area and the target reference position may be obtained based on the target reference position and the area position information of the target area, and then the second signal transmission loss may be calculated based on the second distance and the signal transmission frequency. The region position information of the target region may include position information of a plurality of points within the target region, and the target position may be, for example, at least one of a position closest to the target reference position and a position farthest from the target reference position within the target region.
The closer the terminal is to the target reference position, the smaller the first signal transmission loss, and accordingly, the greater the probability that the second signal transmission loss is greater than the first signal transmission loss. The farther the terminal is from the target reference position, the greater the first signal transmission loss and, correspondingly, the less the probability that the second signal transmission loss is greater than the first signal transmission loss.
In step 103, the signal strength of the cellular network is detected in case the second signal transmission loss is larger than the first signal transmission loss.
For example, if the obtained second signal transmission loss is greater than the first signal transmission loss, which indicates that there is a greater possibility that the cellular network exists at the current location of the terminal, the signal strength of the cellular network may be detected, and the terminal may be switched from the satellite communication network to the cellular network when the signal strength is greater than the preset signal strength threshold, and continue to use the satellite communication network for communication when the signal strength is less than or equal to the preset signal strength threshold. If the obtained second signal transmission loss is smaller than or equal to the first signal transmission loss, which indicates that the current location of the terminal has a smaller possibility of having a cellular network, the signal strength of the cellular network may not be detected. In this way, through the magnitude relation between the second signal transmission loss and the first signal transmission loss, the probability that the cellular network exists at the current position of the terminal is determined, the cellular network is detected under the condition that the probability that the cellular network exists is larger, the cellular network is not detected under the condition that the probability that the cellular network exists is smaller, the cellular network can be detected more effectively, and the waste of network resources of the terminal is reduced.
In summary, in the case that the terminal enters the target area, the present disclosure determines the first signal transmission loss according to the target reference position, the terminal position information of the terminal, and the signal transmission frequency of the target base station corresponding to the target reference position, and determines the second signal transmission loss according to the target reference position, the area position information of the target area, and the signal transmission frequency. In the case that the second signal transmission loss is greater than the first signal transmission loss, the signal strength of the cellular network is detected. In the method, when the terminal is positioned in the target area, whether the signal intensity of the cellular network is detected is determined according to the signal transmission loss of the terminal and the target area relative to the target reference position, the signal intensity of the cellular network can be detected according to the probability of the existence of the cellular network, and invalid signal intensity detection is reduced.
Fig. 4 is a flowchart illustrating another method of detecting signal strength according to an exemplary embodiment, and as shown in fig. 4, step 102 may be implemented by:
in step 1021, a maximum distance between the target region and the target reference position, and a minimum distance between the target region and the target reference position are determined from the region position information.
In step 1022, a second signal transmission loss is determined based on the maximum distance, the minimum distance, and the signal transmission frequency.
For example, since a plurality of points are included in the target area, the area position information of the target area may include position information of the plurality of points, respectively. The more distant a point from the target reference position in the target area, the larger the corresponding signal transmission loss, and the more proximal a point from the target reference position in the target area, the smaller the corresponding signal transmission loss, so that a first position farthest from the target reference position and a first distance between the first position and the target reference position, and a second position closest to the target reference position and a second distance between the second position and the target reference position can be obtained according to a plurality of position information included in the area position information, wherein the first distance is a maximum distance between the target area and the target reference position, and the second distance is a minimum distance between the target area and the target reference position.
After obtaining the maximum distance and the minimum distance between the target region and the target reference position, the second signal transmission loss may be determined according to the maximum distance, the minimum distance, and the signal transmission frequency. In some embodiments, the maximum path loss may be derived from the maximum distance and the signal transmission frequency, and the minimum path loss may be determined from the minimum distance and the signal transmission frequency, and then the second signal transmission loss may be determined between the maximum path loss and the minimum path loss according to a preset random algorithm. In this way, the smaller the first signal transmission loss is, the larger the probability that the second signal transmission loss is larger than the first signal transmission loss is, that is, the closer the terminal is to the target reference position, the larger the probability of detecting the cellular network is, the cellular network can be detected more effectively, and the waste of terminal network resources is reduced.
Taking the signal transmission loss as free space path loss as an example, the maximum distance can be calculatedd max And signal transmission frequencyfThe maximum path loss is obtained by equation 1D max And according to the minimum distanced min And signal transmission frequencyfThe minimum path loss is obtained by equation 2D min . Then according to a preset random algorithm, the maximum path loss is calculated by a formula 3D max And minimum path lossD min Between determining the second signal transmission lossD meas That is, the second signal transmission loss is greater than the minimum path loss and less than the maximum path loss.
(equation 1)
(equation 2)
(equation 3)
Accordingly, the distance between the terminal and the target reference position can be determinedd 0 And signal transmission frequencyfThe first signal transmission loss is obtained by equation 4D thresh 。
(equation 4)
The terminal is located in the target area, the closer the terminal is to the target reference position, the smaller the first signal transmission loss, and accordingly, the larger the probability that the second signal transmission loss determined between the maximum path loss and the minimum path loss according to a preset random algorithm is larger than the first signal transmission loss, the terminal can detect the cellular network under the condition that the probability of the existence of the cellular network is larger, and the cellular network is not detected under the condition that the probability of the existence of the cellular network is smaller, so that the cellular network can be detected more effectively, and the waste of terminal network resources is reduced.
Fig. 5 is a flowchart illustrating a method of determining a target area according to an exemplary embodiment, as shown in fig. 5, the target area being obtained by:
in step 201, a pending area with probability of existence of the cellular network within a preset probability range is determined according to the target reference position.
And 202, taking the undetermined area as a target area.
For example, in the case that the terminal communicates through the satellite communication network, the pending area having a probability of existence of the cellular network within a preset probability range may be determined according to the target reference location, and the pending area may be taken as the target area. The upper limit of the preset probability range may be greater than 0, the lower limit of the preset probability range may be less than 1, and the preset probability range may be (0, 1), for example, that is, the probability that a cellular network exists at any position in the pending area is greater than 0 and less than 1, that is, the pending area may be an area where a cellular network may exist.
It should be noted that, the target reference position may be obtained by the terminal through the satellite communication network in real time, that is, the terminal may obtain the target reference position determined in real time from the satellite communication network, where the target reference position may also be obtained by the terminal through the cellular network in a preset area within a preset duration, and the preset area may be, for example, a circular area with the terminal as an origin and a radius as a first specified radius. Taking a preset time length of 1 hour and a first specified radius of 100 meters as an example, if the terminal obtains a historical reference position through a cellular network in a circular area with the current position of the terminal as a circle center and the radius of 100 meters within 1 hour, the historical reference position can be used as a target reference position. The target reference position may be, for example, a position where a certain base station near the terminal is located, or may be a position determined according to positions of a plurality of base stations nearest to the terminal, which is not particularly limited in the present disclosure.
In some embodiments, a first area where a cellular network exists may be determined according to a target reference location, and a second area where no cellular network exists may be determined according to the target reference location, and then an area other than the first area and the second area may be taken as a pending area. In other embodiments, the area to be determined may be determined directly according to the target reference position, for example, a circle with the target reference position as a center and a radius of a second designated radius may be determined, and a circle with the target reference position as a center and a radius of a third designated radius may be determined, and an annular area between the two circles is taken as the area to be determined, which is not particularly limited in the present disclosure.
Fig. 6 is a flowchart illustrating another method of determining a target area according to an exemplary embodiment, and as shown in fig. 6, step 201 may be implemented by:
in step 2011, a first area where a cellular network is present and a second area where no cellular network is present are determined from the target reference location.
In step 2012, the areas other than the first area and the second area are regarded as pending areas.
For example, a first area where a cellular network is present and a second area where no cellular network is present may be first divided according to a target reference location. As shown in fig. 7, the area inside the ellipse E may be a first area where it is determined that a cellular network exists, the area to the left of the arc F may be a second area where it is determined that no cellular network exists, and the area outside the ellipse area and to the right of the arc F may be a pending area where a cellular network may exist.
In some embodiments, an area within a circle with a first preset radius centered on the target reference position may be used as a first area, an area outside the circle with a second preset radius centered on the target reference position may be used as a second area, and an area between the first area and the second area may be used as a pending area, where the first preset radius is smaller than the second preset radius. In other embodiments, an area within a circle with a third preset radius centered on the target reference position may be used as the first area, and an area within a circle with a fourth preset radius centered on the designated position may be used as the second area. The specified position may be a position at a specified distance from the target reference position in the preset direction, and the specified position may be one or more, for example, a position at 500 meters from the target reference position in the forward east, forward west, forward south, and forward north may be taken as the specified position, and then an area other than the first area and the second area may be taken as the area to be determined. The method for determining the region to be determined in the present disclosure is not particularly limited.
If the terminal is located in the first area, indicating that the cellular network is present at the location of the terminal, the signal strength of the cellular network may be continuously detected to switch to the cellular network in time in the presence of the cellular network. If the terminal is located in the second area, which means that the location of the terminal does not have a cellular network, the signal strength of the cellular network may not be detected, so as to avoid waste of network resources of the terminal.
In summary, in the case that the terminal enters the target area, the present disclosure determines the first signal transmission loss according to the target reference position, the terminal position information of the terminal, and the signal transmission frequency of the target base station corresponding to the target reference position, and determines the second signal transmission loss according to the target reference position, the area position information of the target area, and the signal transmission frequency. In the case that the second signal transmission loss is greater than the first signal transmission loss, the signal strength of the cellular network is detected. In the method, when the terminal is positioned in the target area, whether the signal intensity of the cellular network is detected is determined according to the signal transmission loss of the terminal and the target area relative to the target reference position, the signal intensity of the cellular network can be detected according to the probability of the existence of the cellular network, and invalid signal intensity detection is reduced.
