Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The signal access method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. The wireless signal sources can be indoor signal sources or outdoor signal sources, and overlapping areas may exist between signal coverage areas of different wireless signal sources. The UE (User Equipment) 101 moves in the signal coverage of a plurality of radio signal sources.
Taking the first wireless signal source 102 and the second wireless signal source 103 as an example, an overlapping area between signal coverage areas of the first wireless signal source 102 and the second wireless signal source 103 is denoted as an a-B area, an area of the signal coverage area of the first wireless signal source 102 that does not overlap with the signal coverage area of the second wireless signal source 103 is denoted as an a area, an area of the signal coverage area of the second wireless signal source 103 that does not overlap with the signal coverage area of the first wireless signal source 102 is denoted as a B area, wherein a boundary line between the a area and the a-B area is denoted as L1, and a boundary line between the B area and the a-B area is denoted as L2.
Specifically, when the UE is located in L1, if the radio signal source currently accessed by the UE is the first radio signal source 102, the UE maintains the radio signal source currently accessed unchanged, and when the UE is located in L2, if the radio signal source currently accessed by the UE is the second radio signal source 103, the UE maintains the radio signal source currently accessed unchanged.
The UE101 may be, but not limited to, various mobile personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, where the internet of things devices may be smart speakers, smart car devices, and the like, and the portable wearable devices may be smart watches, smart bracelets, headsets, and the like. The wireless signal source may be, but not limited to, various indoor or outdoor wireless signal sources such as WiFi signal sources and bluetooth signal sources.
In one embodiment, as shown in fig. 2, there is provided a signal access method, including the steps of:
s201, under the condition that the UE is determined to be located in the signal coverage area of at least two wireless signal sources currently and located in the signal coverage boundary of any wireless signal source, whether the wireless signal source which is accessed currently is a target wireless signal source in the at least two wireless signal sources is determined.
The wireless signal sources are WiFi signal sources, bluetooth signal sources, etc. deployed indoors or outdoors, the type of the wireless signal sources is not limited in this embodiment, and the wireless signal sources may be different types of wireless signal sources, that is, UEs move in signal coverage areas of different types of wireless signal sources.
Based on the real-time location of the UE, it may be determined whether the UE is located within the signal coverage area of at least two wireless signal sources. For example, the wireless signal source is a wireless signal source with a relatively fixed location, and the location of the signal coverage area is also relatively fixed, so that whether the UE is located in the signal coverage area can be determined based on the real-time location of the UE and the location of the signal coverage area.
Based on the signal strengths of the wireless signal sources received by the UE, it may be determined whether the UE is located within the signal coverage areas of at least two of the wireless signal sources. For example, the wireless signal source is a mobile wireless signal source, and the UE may acquire the signal strength of the wireless signal source in real time, so as to determine whether the UE is located in the signal coverage area based on the signal strength.
For each wireless signal source, the relevant parameters of the corresponding signal coverage boundary are preset, for example, when the UE accesses a certain wireless signal source for the first time, the relevant parameters of the signal coverage boundary of the wireless signal source are obtained, and then in the moving process of the UE, whether the UE is positioned at the signal coverage boundary of the wireless signal source can be determined based on the real-time position of the UE. The relevant parameter of the signal coverage boundary may be a geographic location or a signal strength corresponding to the signal coverage boundary.
In the case that it is determined that the UE is currently located in the signal coverage areas of the plurality of wireless signal sources and the UE is being located at the signal coverage boundary of one of the wireless signal sources, if the UE moves back and forth at the signal coverage boundary, a problem of jitter may occur in the UE signal access. Thus, for this case, it is determined whether the wireless signal source currently accessed by the UE is a target wireless signal source of the plurality of wireless signal sources, wherein the target wireless signal source is any wireless signal source other than the wireless signal source to which the signal coverage boundary belongs.
Taking the signal coverage areas of the two wireless signal sources as an example, an overlapping area exists between the signal coverage areas of the first wireless signal source and the second wireless signal source, the UE is currently located at the signal coverage boundary of the second wireless signal source, and the signal coverage boundary of the second wireless signal source is within the signal coverage area of the first wireless signal source, i.e. the UE is currently located at the signal coverage area of the first wireless signal source and the signal coverage boundary of the second wireless signal source at the same time. The wireless signal source to which the signal coverage boundary belongs is the second wireless signal source, so that the target wireless signal source is the first wireless signal source.
When the UE is currently located in the signal coverage areas of more than two wireless signal sources, the manner of determining the target wireless signal source is similar, and will not be described in detail, it will be understood that there may be multiple target wireless signal sources at this time.
Further, whether the wireless signal source accessed by the UE at present is a target wireless signal source is judged, and different signal access modes are adopted under different conditions.
S202, when the wireless signal source which is accessed currently is the target wireless signal source, the wireless signal source which is accessed currently is maintained unchanged.
Specifically, whether the wireless signal source currently accessed by the UE is a target wireless signal source is judged, and if the wireless signal source is the target wireless signal source, the wireless signal source currently accessed is maintained unchanged. For example, when the wireless signal source currently accessed by the UE is the first wireless signal source, the UE moves back and forth at the signal coverage boundary of the second wireless signal source, so that the problem of unstable signal access does not occur, and therefore the currently accessed wireless signal source is maintained unchanged as the first wireless signal source.
In the above scheme, under the condition that the UE is determined to be currently located in the signal coverage areas of at least two wireless signal sources and located in the signal coverage boundary of any wireless signal source, whether the currently accessed wireless signal source is a target wireless signal source in the at least two wireless signal sources is determined; if the wireless signal source is the target wireless signal source, the wireless signal source which is accessed currently is maintained unchanged. The embodiment supports that when the UE moves back and forth on the boundary line of the coverage areas of the plurality of wireless signal sources, the unaffected target wireless signal source is actively determined from the plurality of wireless signal sources, so that signal access is kept unchanged under the condition that the currently accessed wireless signal source is the target wireless signal source, the frequently switched connected wireless signal sources are avoided, the UE can reasonably access the plurality of wireless signal sources in the moving process, the influence of the back and forth movement of the UE on the boundary line is avoided, and the stability of the signal access of the UE is ensured.
In order to enable the UE to reasonably access among the plurality of wireless signal sources in the moving process, in an embodiment, when the currently accessed wireless signal source is not the target wireless signal source, the method for accessing the signal may switch to the target wireless signal source to access the signal, as shown in fig. 3, where the method for accessing the signal may further include:
s301, determining whether the currently accessed wireless signal source is a target wireless signal source in at least two wireless signal sources under the condition that the UE is determined to be located in the signal coverage areas of the at least two wireless signal sources and located in the signal coverage boundary of any wireless signal source.
In the case that it is determined that the UE is currently located in the signal coverage areas of the plurality of wireless signal sources and the UE is being located at the signal coverage boundary of one of the wireless signal sources, if the UE moves back and forth at the signal coverage boundary, a problem of jitter may occur in the UE signal access. Thus, for this case, it is determined whether the wireless signal source currently accessed by the UE is a target wireless signal source of the plurality of wireless signal sources, wherein the target wireless signal source is any wireless signal source other than the wireless signal source to which the signal coverage boundary belongs.
Taking the signal coverage areas of the two wireless signal sources as an example, an overlapping area exists between the signal coverage areas of the first wireless signal source and the second wireless signal source, the UE is currently located at the signal coverage boundary of the second wireless signal source, and the signal coverage boundary of the second wireless signal source is within the signal coverage area of the first wireless signal source, i.e. the UE is currently located at the signal coverage area of the first wireless signal source and the signal coverage boundary of the second wireless signal source at the same time. The wireless signal source to which the signal coverage boundary belongs is the second wireless signal source, so that the target wireless signal source is the first wireless signal source.
When the UE is currently located in the signal coverage areas of more than two wireless signal sources, the manner of determining the target wireless signal source is similar, and will not be described in detail, it will be understood that there may be multiple target wireless signal sources at this time.
Further, whether the wireless signal source accessed by the UE at present is a target wireless signal source is judged, and different signal access modes are adopted under different conditions.
S302, switching to the target wireless signal source under the condition that the wireless signal source which is accessed currently is not the target wireless signal source.
Specifically, whether the wireless signal source accessed by the UE at present is a target wireless signal source is judged, and if the wireless signal source is not the target wireless signal source, the wireless signal source is switched to the target wireless signal source. For example, if the radio signal source currently accessed by the UE is the second radio signal source, the UE moves back and forth at the signal coverage boundary of the second radio signal source, which causes a problem of unstable signal access, so that the radio signal source currently accessed by the UE is switched from the second radio signal source to the first radio signal source.
In the above scheme, under the condition that the UE is determined to be currently located in the signal coverage areas of at least two wireless signal sources and located in the signal coverage boundary of any wireless signal source, whether the currently accessed wireless signal source is a target wireless signal source in the at least two wireless signal sources is determined; if the signal source is not the target wireless signal source, switching to the target wireless signal source. According to the embodiment, the signal superposition area is defined among the plurality of wireless signal sources, when the UE is supported to move back and forth on the boundary line of the coverage areas of the plurality of wireless signal sources, the unaffected target wireless signal source is actively determined from the plurality of wireless signal sources, so that the UE is switched to the target wireless signal source for access under the condition that the currently accessed wireless signal source is not the target wireless signal source, smooth switching is realized, the problem of jitter is avoided, the UE is reasonably accessed in the plurality of wireless signal sources in the moving process, the influence of the back and forth movement of the UE on the boundary line is avoided, and the stability of the signal access of the UE is ensured.
In order to reasonably determine whether the UE is located in the signal coverage area of the wireless signal source and whether the UE is located in the signal coverage boundary of the wireless signal source, in one embodiment, as shown in fig. 4, the signal access method may further include:
s401, acquiring the signal strength of each wireless signal source currently received by the UE in the moving process of the UE.
During the movement of the UE, the signal strength of the radio signal source received by the UE is constantly changing. The UE can receive peripheral wireless signals in real time based on the terminal signal acquisition module and output the signal intensity of a wireless signal source corresponding to each wireless signal.
S402, for any wireless signal source, determining whether the UE is located in a signal coverage area of the wireless signal source and is located in a signal coverage boundary of the wireless signal source according to the magnitude relation between the signal strength of the wireless signal source and the corresponding strength threshold.
According to the magnitude relation between the signal intensity of each wireless signal source and the corresponding intensity threshold value, whether the UE is located in the signal coverage area of each wireless signal source can be determined, and whether the UE is located in the signal coverage area of at least two wireless signal sources or not, namely whether the UE is located in the overlapping area between the signal coverage areas of a plurality of wireless signal sources or not can be obtained based on whether the UE is located in the signal coverage area of each wireless signal source or not.
In addition, according to the magnitude relation between the signal intensity of each wireless signal source and the corresponding intensity threshold value, whether the UE is positioned at the signal coverage boundary of each wireless signal source can be determined, and whether the UE is positioned at the signal coverage boundary of any wireless signal source can be obtained based on whether the UE is positioned at the signal coverage boundary of each wireless signal source. Optionally, the UE determines, based on the terminal signal handover control module, whether the UE reaches the active boundary of the currently connected wireless signal source.
Specifically, for any wireless signal source, the UE stores an intensity threshold corresponding to the wireless signal source in advance, and determines whether the UE is located in a signal coverage area of the wireless signal source and is located in a signal coverage boundary of the wireless signal source by comparing the signal intensity of the wireless signal source determined in real time with the intensity threshold.
In an alternative embodiment, if the signal strength of the wireless signal source is greater than the corresponding strength threshold, determining that the UE is located in the signal coverage area of the wireless signal source; if the signal strength of the wireless signal source is smaller than the corresponding strength threshold, determining that the UE is not located in the signal coverage area of the signal source.
The intensity threshold may be a fixed value or a smaller threshold range. Under the condition that the intensity threshold value is in a smaller threshold value range, if the signal intensity of the wireless signal source is larger than the uplink of the intensity threshold value, determining that the UE is positioned in a signal coverage area of the wireless signal source; if the signal strength of the wireless signal source is less than the infinitesimal limit of the strength threshold, determining that the UE is not located in the signal coverage area of the signal source.
In an alternative embodiment, if the signal strength of the wireless signal source is equal to the corresponding strength threshold, it is determined that the UE is located at the signal coverage boundary of the wireless signal source.
The intensity threshold may be a fixed value or a smaller threshold range. If the signal strength of the radio signal source belongs to the threshold range, determining that the UE is located at the signal coverage boundary of the radio signal source.
In the moving process of the UE, the signal intensity of each wireless signal source currently received by the UE is obtained, and according to the magnitude relation between the signal intensity of each wireless signal source and the corresponding intensity threshold value, whether the UE is located in the signal coverage area of each wireless signal source or not and whether the UE is located in the signal coverage boundary of each wireless signal source or not is determined, and the signal intensities of different wireless signal sources are not required to be compared, so that the wireless signal sources are not required to be the same type of wireless signal source, a wider application scene is provided for the signal access method, and the rationality and the accuracy of a judgment result are ensured.
In order to achieve reasonable signal access when the UE is not located at the signal coverage boundary of any wireless signal source, in one embodiment, an initial wireless signal source may be selected from at least two wireless signal sources, as shown in fig. 5, and the signal access method may further include:
s501, initializing a wireless signal source which is accessed by the UE currently.
Before the UE accesses any wireless signal source, initializing the UE, and judging the current position of the UE, thereby selecting the wireless signal source of initial access. It will be appreciated that at this point the UE has not yet access to any of the wireless signal sources.
Optionally, devices such as a Bluetooth beacon, a UWB base station and the like are deployed indoors, so that the UE can automatically switch and select proper devices as reference points to perform indoor positioning in the moving process.
S502, under the condition that the UE is determined to be located in the signal coverage areas of at least two wireless signal sources currently and is not located in the signal coverage boundary of any wireless signal source, determining the wireless signal source which needs to be accessed currently from the at least two wireless signal sources.
Based on the real-time location of the UE and/or the received signal strengths of the wireless signal sources, it is determined whether the UE is located in the signal coverage areas of at least two wireless signal sources and is located at the signal coverage boundary of any of the wireless signal sources. For example, an intensity threshold corresponding to the signal intensity of the received wireless signal sources is obtained, and whether the UE is located in the signal coverage areas of at least two wireless signal sources and whether the UE is located in the signal coverage boundary of any wireless signal source are determined according to the magnitude relation between the signal intensity and the intensity threshold.
Further, in the case where it is determined that the UE is currently located in the signal coverage areas of the plurality of wireless signal sources and the UE is not located at the signal coverage boundary of any one of the wireless signal sources, it is necessary to determine the initially accessed wireless signal source from the received wireless signal sources.
Taking the signal coverage areas of the two wireless signal sources as an example, where an overlapping area exists between the signal coverage areas of the first wireless signal source and the second wireless signal source, when the UE is located in the overlapping area, one wireless signal source is arbitrarily selected from the first wireless signal source and the second wireless signal source to access.
Optionally, the UE connects with the designated wireless signal source based on the terminal signal connection module.
When the UE is currently located in the signal coverage areas of more than two wireless signal sources, the manner of determining the wireless signal source to be accessed is similar, and will not be described again.
The method and the device initialize the wireless signal source which the UE is currently connected to, and determine the wireless signal source which is currently required to be connected to from at least two wireless signal sources under the condition that the UE is determined to be positioned in the signal coverage areas of at least two wireless signal sources and is not positioned in the signal coverage boundary of any wireless signal source, so that a mode of connecting to the wireless signal source under the condition that the UE is not positioned in the signal coverage boundary is provided for the UE, a wider application scene is provided for the signal connection method, and the rationality of signal connection is ensured.
In one embodiment, an alternative example of a signal access method is provided, as shown in fig. 6, and the specific procedure is as follows:
s601, initializing a wireless signal source which is accessed by the UE currently.
S602, acquiring the signal strength of each wireless signal source currently received by the UE in the moving process of the UE.
S603, determining whether the UE is located in the signal coverage area of each wireless signal source and whether the UE is located in the signal coverage boundary of each wireless signal source according to the magnitude relation between the signal strength of each wireless signal source and the corresponding strength threshold.
S604, in a case where it is determined that the UE is currently located in the signal coverage areas of at least two wireless signal sources and is not located in the signal coverage boundary of any wireless signal source, determining a currently accessed wireless signal source from the at least two wireless signal sources.
S605, in the moving process of the UE, the signal strength of each wireless signal source currently received by the UE is obtained.
S606, determining whether the UE is positioned in the signal coverage area of each wireless signal source and whether the UE is positioned in the signal coverage boundary of each wireless signal source according to the magnitude relation between the signal intensity of each wireless signal source and the corresponding intensity threshold.
S607, in the case that it is determined that the UE is currently located in the signal coverage areas of at least two wireless signal sources and is located in the signal coverage boundary of any wireless signal source, it is determined whether the currently accessed wireless signal source is a target wireless signal source of the at least two wireless signal sources.
The target wireless signal source is any wireless signal source except the wireless signal source to which the signal coverage boundary belongs.
And S608, maintaining the wireless signal source which is accessed at present unchanged under the condition that the wireless signal source which is accessed at present is the target wireless signal source.
S609, switching to the target wireless signal source under the condition that the wireless signal source which is accessed currently is not the target wireless signal source.
