The network side device provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), a network side device in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), a cell (cell), or the like), or a network side device in a subsequent evolved communication system. However, the above words are not to be construed as limiting the scope of the invention.
Fig. 1 shows a schematic flow chart of a signal quality improvement method according to an embodiment of the present invention. The signal quality improvement method may include:
s101: and receiving a neighbor cell verification request message sent by the terminal equipment.
The neighbor cell verification request message at least comprises service cell information corresponding to a first Subscriber Identity Module (SIM) and service cell information corresponding to a second SIM; the first SIM and the second SIM are installed in the terminal equipment; and the neighbor cell verification request message is sent by the terminal equipment when the terminal equipment meets the preset condition.
In one embodiment of the present invention, the preset condition may include: within the signal quality comparison duration threshold, the frequency point corresponding to the serving cell corresponding to the second SIM is different from the frequency point corresponding to the serving cell corresponding to the first SIM, the signal quality of the second SIM is always lower than the target signal quality threshold, and the signal quality difference value between the signal quality of the first SIM and the signal quality of the second SIM is always higher than the signal quality difference threshold.
S102: detecting whether the service cell corresponding to the first SIM is a neighbor cell of the service cell corresponding to the second SIM or not according to the neighbor cell verification request message; if not, S103 is executed.
S103: and configuring the serving cell corresponding to the first SIM as a neighboring cell of the serving cell corresponding to the second SIM, and executing S112.
In an embodiment of the present invention, the terminal device may install at least two SIMs, and a first SIM and a second SIM of the at least two SIMs may be SIMs provided by the same operator or SIMs provided by different operators. And when the terminal equipment detects that the frequency point corresponding to the service cell corresponding to the second SIM is different from the frequency point corresponding to the service cell corresponding to the first SIM within the signal quality comparison duration threshold, the signal quality of the second SIM is always lower than the target signal quality threshold, and the signal quality difference value between the signal quality of the first SIM and the signal quality of the second SIM is always higher than the signal quality difference threshold, sending a neighbor cell verification request message to the network side equipment.
In an embodiment of the present invention, the neighbor cell verification request message received by the network-side device is a neighbor cell verification request message of a network in which the second SIM of the terminal device is located.
After receiving the neighbor cell verification request message sent by the terminal device, the network side device detects whether the serving cell corresponding to the first SIM is a neighbor cell of the serving cell corresponding to the second SIM.
If the service cell corresponding to the first SIM is not detected to be the neighbor cell of the service cell corresponding to the second SIM, the service cell corresponding to the first SIM is configured to be the neighbor cell of the service cell corresponding to the second SIM, so that the terminal equipment can reselect or switch to the service cell corresponding to the first SIM when performing pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and the signal quality of the second SIM can be improved.
For example, it is assumed that a 1282 frequency cell corresponding to the first SIM and a 38400 frequency cell corresponding to the second SIM are not configured in a neighbor cell relationship. When the terminal equipment reselects or switches the pilot frequency cell based on the second SIM, the cell of the 1282 frequency point cannot be measured, so that the second SIM cannot reside in the cell of the 1282 frequency point.
In the method for improving signal quality provided by the embodiment of the invention, the 1282 frequency point cell corresponding to the first SIM is configured as a neighbor cell of the 38400 frequency point cell corresponding to the second SIM. When the pilot frequency cell reselection or the pilot frequency cell switching is carried out on the basis of the second SIM, the terminal equipment can measure the 1282 frequency point cell, so that the terminal equipment can reselect or switch to the 1282 frequency point cell when the pilot frequency cell reselection or the pilot frequency cell switching is carried out on the basis of the second SIM, the 1282 frequency point cell can be resided by the second SIM, and the signal quality of the second SIM is improved. Meanwhile, the problem that the difference of the signal quality of the first SIM and the second SIM is large due to the missing configuration of the adjacent cell can be solved.
In an embodiment of the present invention, if the serving cell corresponding to the first SIM is a neighboring cell of the serving cell corresponding to the second SIM, S104 is performed.
S104: whether the frequency point corresponding to the service cell corresponding to the first SIM is configured in a pilot frequency carrier list (InterFreqCarrierFreqList) corresponding to the second SIM is detected. If the frequency point corresponding to the serving cell corresponding to the first SIM is configured in the pilot frequency carrier list, S105 is performed.
S105: and detecting whether the parameters corresponding to the frequency points corresponding to the service cell corresponding to the first SIM are in a normal range, and if not, executing S106.
S106: and adjusting the parameters corresponding to the frequency point corresponding to the serving cell corresponding to the first SIM to the normal range, and executing S112.
For example, suppose that a 1282 frequency cell corresponding to the first SIM and a 38400 frequency cell corresponding to the second SIM are in a neighboring cell relationship. At this time, the 1282 frequency point may be located in the list of pilot carriers corresponding to the second SIM, or may be located in an extension list (inter freq carrier freq list) of pilot carriers corresponding to the second SIM.
Supposing that the 1282 frequency point is located in the pilot frequency carrier list corresponding to the second SIM, but the parameter corresponding to the 1282 frequency point is not in the normal range, so that when the terminal device performs pilot frequency cell reselection or pilot frequency cell handover based on the second SIM, although the 1282 frequency point cell can be measured, the 1282 frequency point cell cannot be resided in the second SIM due to the fact that the parameter corresponding to the 1282 frequency point is not in the normal range.
According to the signal quality improving method provided by the embodiment of the invention, the parameters corresponding to the 1282 frequency point are adjusted to the normal range, so that the 1282 frequency point cell can be resided in the second SIM, and the signal quality of the second SIM is improved. Meanwhile, the problem that the difference of the signal quality of the first SIM and the second SIM is large due to unreasonable parameter configuration corresponding to the frequency point can be solved.
In an embodiment of the present invention, if the frequency point corresponding to the serving cell corresponding to the first SIM is configured in the pilot frequency carrier extension list corresponding to the second SIM, S107 is performed.
S107: and adjusting the frequency point corresponding to the serving cell corresponding to the first SIM to the pilot frequency carrier list, and executing S112.
Exemplarily, assuming that the 1282 frequency point corresponding to the first SIM is located in the pilot frequency carrier extension list corresponding to the second SIM, because some terminal devices do not support the function of measuring the frequency points in the pilot frequency carrier extension list, when the terminal device reselects or switches the pilot frequency cell based on the second SIM, the cell of the 1282 frequency point located in the pilot frequency carrier extension list corresponding to the second SIM is not measured, so that the second SIM cannot reside in the cell of the 1282 frequency point.
According to the signal quality improving method provided by the embodiment of the invention, the 1282 frequency point corresponding to the first SIM is configured in the pilot frequency carrier list corresponding to the second SIM, so that the 1282 frequency point cell can be measured when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and further, the 1282 frequency point cell can be reselected or switched to when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and the 1282 frequency point cell can be resided in the second SIM, so that the signal quality of the second SIM is improved. Meanwhile, the problem that the difference of the signal quality of the first SIM and the second SIM is large due to the fact that the terminal equipment does not support the function of measuring the frequency points in the pilot frequency carrier extension list is solved.
In an embodiment of the present invention, if the number of the frequency points in the pilot frequency carrier list does not reach the preset number, the frequency point corresponding to the serving cell corresponding to the first SIM is adjusted to the pilot frequency carrier list.
Exemplarily, it is assumed that a 1282 frequency point corresponding to a first SIM is located in a pilot frequency carrier extension list corresponding to a second SIM, the preset number is 10, and the number of frequency points in the pilot frequency carrier list corresponding to the second SIM is 5 currently.
And if the number of the frequency points in the pilot frequency carrier list corresponding to the current second SIM does not reach the preset number, directly adjusting the 1282 frequency points corresponding to the first SIM into the pilot frequency carrier list.
According to the signal quality improving method provided by the embodiment of the invention, the 1282 frequency point corresponding to the first SIM is configured in the pilot frequency carrier list corresponding to the second SIM, so that the 1282 frequency point cell can be measured when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and further, the 1282 frequency point cell can be reselected or switched to when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and the 1282 frequency point cell can be resided in the second SIM, so that the signal quality of the second SIM is improved. Meanwhile, the problem that the difference of the signal quality of the first SIM and the second SIM is large due to the fact that the terminal equipment does not support the function of measuring the frequency points in the pilot frequency carrier extension list is solved.
In an embodiment of the present invention, if the number of the frequency points in the pilot frequency carrier list reaches a preset number, one frequency point is selected from the pilot frequency carrier list to perform position exchange with the frequency point corresponding to the serving cell corresponding to the first SIM.
Exemplarily, it is assumed that a 1282 frequency point corresponding to a first SIM is located in a pilot frequency carrier extension list corresponding to a second SIM, the preset number is 10, and the number of frequency points in the pilot frequency carrier list corresponding to the second SIM is 10 currently.
When the number of the frequency points in the pilot frequency carrier list corresponding to the second SIM reaches the preset number, one frequency point can be selected from the pilot frequency carrier list corresponding to the second SIM to perform position exchange with the 1282 frequency point. Namely, the 1282 frequency point in the pilot frequency carrier expansion list corresponding to the second SIM is adjusted to the pilot frequency carrier list corresponding to the second SIM, and one frequency point selected from the pilot frequency carrier list corresponding to the second SIM is adjusted to the pilot frequency carrier expansion list corresponding to the second SIM.
According to the signal quality improving method provided by the embodiment of the invention, the 1282 frequency point corresponding to the first SIM is configured in the pilot frequency carrier list corresponding to the second SIM, so that the 1282 frequency point cell can be measured when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and further, the 1282 frequency point cell can be reselected or switched to when the terminal equipment performs pilot frequency cell reselection or pilot frequency cell switching based on the second SIM, and the 1282 frequency point cell can be resided in the second SIM, so that the signal quality of the second SIM is improved. Meanwhile, the problem that the difference of the signal quality of the first SIM and the second SIM is large due to the fact that the terminal equipment does not support the function of measuring the frequency points in the pilot frequency carrier extension list is solved.
In an embodiment of the present invention, the neighbor cell verification request message may include: and the pilot frequency points of the adjacent region corresponding to the second SIM. Based on this, the network side device can detect whether each frequency point in the pilot frequency carrier list is in the pilot frequency point in the neighboring cell corresponding to the second SIM and included in the neighboring cell verification request message sent by the terminal device, if it is detected that each frequency point in the pilot frequency carrier list is in the pilot frequency point in the neighboring cell corresponding to the second SIM included in the neighbor cell verification request message sent by the terminal device, selecting the frequency point with the weakest signal intensity in the pilot frequency points in the adjacent region corresponding to the second SIM from the pilot frequency carrier list, exchanging the position of the selected frequency point with the frequency point corresponding to the first SIM configured in the pilot frequency carrier list corresponding to the second SIM, namely, the frequency points in the pilot frequency carrier expansion list corresponding to the second SIM are adjusted to the pilot frequency carrier list corresponding to the second SIM, and adjusting the frequency point with the weakest signal intensity in the pilot frequency points in the adjacent region corresponding to the second SIM in the pilot frequency carrier list corresponding to the second SIM to the pilot frequency carrier extension list corresponding to the second SIM.
Exemplarily, it is assumed that a 1282 frequency point corresponding to a first SIM is located in a pilot frequency carrier extension list corresponding to a second SIM, the preset number is 5, and the number of frequency points in the pilot frequency carrier list corresponding to the second SIM is 5 currently. The frequency points in the pilot frequency carrier list corresponding to the current second SIM are respectively a frequency point A, a frequency point B, a frequency point C, a frequency point D and a frequency point E; the neighbor cell verification request message sent by the terminal device includes neighbor cell pilot frequency points corresponding to the second SIM, which include frequency point a, frequency point B, frequency point C, frequency point D and frequency point E, wherein the signal strength of frequency point C is the weakest. And performing position interchange on the frequency point C and the frequency point 1282, namely adjusting the frequency point 1282 in the pilot frequency carrier expansion list corresponding to the second SIM into the pilot frequency carrier list corresponding to the second SIM, and adjusting the frequency point C in the pilot frequency carrier list corresponding to the second SIM into the pilot frequency carrier expansion list corresponding to the second SIM.
In an embodiment of the present invention, the neighbor cell verification request message may include: and the pilot frequency points of the adjacent region corresponding to the second SIM. Based on this, the network side device can detect whether each frequency point in the pilot frequency carrier list is in the pilot frequency point in the neighboring cell corresponding to the second SIM and included in the neighboring cell verification request message sent by the terminal device, if it is detected that a frequency point in the pilot frequency carrier list is not located in the pilot frequency point in the neighboring cell corresponding to the second SIM included in the neighboring cell verification request message sent by the terminal device, then the positions of the frequency points which are not in the adjacent area pilot frequency point corresponding to the second SIM in the pilot frequency carrier list are exchanged with the frequency points corresponding to the first SIM configured in the pilot frequency carrier list corresponding to the second SIM, namely, the frequency points in the pilot frequency carrier expansion list corresponding to the second SIM are adjusted to the pilot frequency carrier list corresponding to the second SIM, and adjusting the intermediate frequency point of the pilot frequency point of the neighboring cell which is not corresponding to the second SIM in the pilot frequency carrier list corresponding to the second SIM to the pilot frequency carrier extension list corresponding to the second SIM.
Exemplarily, it is assumed that a 1282 frequency point corresponding to a first SIM is located in a pilot frequency carrier extension list corresponding to a second SIM, the preset number is 5, and the number of frequency points in the pilot frequency carrier list corresponding to the second SIM is 5 currently. The frequency points in the pilot frequency carrier list corresponding to the current second SIM are respectively a frequency point A, a frequency point B, a frequency point C, a frequency point D and a frequency point E; the neighbor cell verification request message sent by the terminal device includes neighbor cell pilot frequency points corresponding to the second SIM, including a frequency point a, a frequency point B, a frequency point C, a frequency point E, and a frequency point F, wherein a frequency point D in a pilot frequency carrier list corresponding to the second SIM is not located in a neighbor cell pilot frequency point corresponding to the second SIM. And performing position interchange on the frequency point D and the frequency point 1282, namely adjusting the frequency point 1282 in the pilot frequency carrier expansion list corresponding to the second SIM into the pilot frequency carrier list corresponding to the second SIM, and adjusting the frequency point D in the pilot frequency carrier list corresponding to the second SIM into the pilot frequency carrier expansion list corresponding to the second SIM.
In an embodiment of the present invention, if the parameter corresponding to the frequency point corresponding to the serving cell corresponding to the first SIM is within the normal range, step S108 is executed.
S108: detecting whether a signal quality comparison time length threshold included by the neighbor cell verification request message reaches a preset time length threshold, whether a signal quality difference threshold included by the neighbor cell verification request message reaches a preset signal quality difference threshold and whether a target signal quality threshold included by the neighbor cell verification request message reaches a preset signal quality threshold; if so, S109 is performed.
S109: and determining that the terminal equipment detects that the frequency point corresponding to the service cell corresponding to the first SIM has a problem, and feeding back a response message which does not comprise a signal quality comparison duration threshold, a signal quality difference threshold and a target signal quality threshold to the terminal equipment.
For example, suppose that a 1282 frequency point cell corresponding to the first SIM and a 38400 frequency point cell corresponding to the second SIM are in a neighboring cell relationship; the 1282 frequency point is located in the pilot frequency carrier list corresponding to the second SIM, and the parameter corresponding to the 1282 frequency point is within the normal range.
The network side equipment detects that the 1282 frequency point cell corresponding to the first SIM is the 38400 frequency point cell corresponding to the second SIM, detects that the 1282 frequency point is located in the pilot frequency carrier list corresponding to the second SIM, and detects that the parameter corresponding to the 1282 frequency point is in the normal range.
At this time, the network side device detects whether a signal quality comparison time length threshold included in a neighbor cell verification request message sent by the terminal device reaches a preset time length threshold, whether a signal quality difference threshold reaches a preset signal quality difference threshold, and whether a target signal quality threshold reaches a preset signal quality threshold; if the network side equipment detects that the signal quality comparison time length threshold included in the neighbor cell verification request message sent by the terminal equipment reaches the preset time length threshold, the signal quality difference threshold reaches the preset signal quality difference threshold, and the target signal quality threshold reaches the preset signal quality threshold, it is determined that the terminal equipment detects the 1282 frequency point, and the problem is conveniently provided to a terminal equipment manufacturer, so that the terminal equipment manufacturer solves the problem. And feeding back a response message to the terminal equipment, wherein the response message does not comprise a signal quality comparison duration threshold, a signal quality difference threshold and a target signal quality threshold.
In an embodiment of the present invention, if it is detected that the signal quality comparison duration threshold does not reach the preset duration threshold, or the signal quality difference threshold does not reach the preset signal quality difference threshold, or the target signal quality threshold does not reach the preset signal quality threshold, S110 is executed.
S110: adjusting a signal quality comparison duration threshold based on a signal quality comparison duration threshold adjustment value, adjusting a signal quality difference threshold based on a signal quality difference threshold adjustment value, and adjusting a target signal quality threshold based on a target signal quality threshold adjustment value.
S111: and sending the adjusted signal quality comparison duration threshold, the adjusted signal quality difference threshold and the adjusted target signal quality threshold to the terminal equipment.
For example, suppose that a 1282 frequency point cell corresponding to the first SIM and a 38400 frequency point cell corresponding to the second SIM are in a neighboring cell relationship; the 1282 frequency point is located in the pilot frequency carrier list corresponding to the second SIM, and the parameter corresponding to the 1282 frequency point is within the normal range.
The network side equipment detects that the 1282 frequency point cell corresponding to the first SIM is the 38400 frequency point cell corresponding to the second SIM, detects that the 1282 frequency point is located in the pilot frequency carrier list corresponding to the second SIM, and detects that the parameter corresponding to the 1282 frequency point is in the normal range.
At this time, the network side device detects whether a signal quality comparison time length threshold included in a neighbor cell verification request message sent by the terminal device reaches a preset time length threshold, whether a signal quality difference threshold reaches a preset signal quality difference threshold, and whether a target signal quality threshold reaches a preset signal quality threshold; if the network side equipment detects that a signal quality comparison time length threshold included in a neighbor cell verification request message sent by the terminal equipment does not reach a preset time length threshold, or a signal quality difference threshold does not reach a preset signal quality difference threshold, or a target signal quality threshold does not reach the preset signal quality threshold, the network side equipment adjusts the signal quality comparison time length threshold based on a signal quality comparison time length threshold adjusting value, adjusts the signal quality difference threshold based on the signal quality difference threshold adjusting value, and adjusts the target signal quality threshold based on the target signal quality threshold adjusting value. And sending the adjusted signal quality comparison duration threshold, the adjusted signal quality difference threshold and the adjusted target signal quality threshold to the terminal equipment. Namely, the response message comprising the adjusted signal quality comparison duration threshold, the adjusted signal quality difference threshold and the adjusted target signal quality threshold is fed back to the terminal equipment.
For example, it is assumed that the preset duration threshold is 10 minutes, the signal quality comparison duration threshold included in the neighbor cell verification request message is 5 minutes, and the signal quality comparison duration threshold adjustment value is 1 minute. When the signal quality comparison duration threshold is adjusted based on the signal quality comparison duration threshold adjustment value, the sum operation may be performed on the signal quality comparison duration threshold (5 minutes) included in the neighbor cell verification request message and the signal quality comparison duration threshold adjustment value (1 minute) to obtain an adjusted signal quality comparison duration threshold (6 minutes), and the adjusted signal quality comparison duration threshold (6 minutes) is sent to the terminal device.
