Description

Cell switching method and device, electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of mobile communications, and in particular, to a cell switching method and apparatus, an electronic device, and a storage medium.

Background

The cell network priority (cell reselection priority) defines the priority of reselection of the service frequency in the inter-frequency cell, and generally takes a value of 0 to 7, and a larger value indicates a higher priority.

Generally, the cell network priority is defined by the network and may be determined, for example, according to the performance, load, etc. of the base station. Meanwhile, the cell can send the cell network selection priority of the cell to the terminal in a mode of broadcasting system information and the like.

In the related art, the terminal performs inter-frequency cell handover based on the priority of the cell network. For example, a terminal will typically always attempt to camp on a cell with a high cell network priority. However, if the terminal has poor received signal quality in a cell with a high cell network priority, a problem such as communication abnormality occurs.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if," as used herein, may be interpreted as "at \8230; \8230when" or "when 8230; \823030when" or "in response to a determination," depending on the context.

In the related art, the terminal may perform cell handover based on the cell network priority. For example, after camping on the serving cell, the terminal generally performs measurement only on a neighbor cell with higher cell selection priority than the serving cell, but does not perform measurement on a neighbor cell with lower cell selection priority. However, if the terminal has poor signal reception quality for the serving cell or the cell with the higher cell selection priority, the communication quality of the terminal is not high.

To this end, the present disclosure proposes a cell handover method to avoid the problems in the related art.

Fig. 1 is a schematic flow chart illustrating a cell handover method according to an embodiment of the present disclosure. The cell switching method shown in this embodiment may be applied to a terminal, where the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with a base station as a user equipment, where the base station includes but is not limited to a base station in a communication system such as a 4G base station, a 5G base station, a 6G base station, and so on.

As shown in fig. 1, the method may include the steps of:

step 101: measuring at least one adjacent cell of the service cell where the terminal is located currently, and determining the signal quality of each adjacent cell signal received by the terminal; wherein, in the at least one neighboring cell, the cell network selection priority of at least one neighboring cell is not higher than the serving cell.

In one embodiment, the terminal may determine the reselection priorities of the neighboring cells and the serving cell where the terminal is currently located through a system message broadcast by the cell.

In the related art, the terminal may determine the neighbor cells to be measured based on the reselection priority. For example, the terminal may compare the reselection priorities of the neighbor cell and the serving cell, and thus determine only a neighbor cell having a higher reselection priority than the current serving cell as a neighbor cell to be measured.

In order to avoid the problem of poor communication quality of the terminal in the related art, in one embodiment, the terminal may ignore the reselection priority, that is, the terminal ignores the influence of the reselection priority when determining the neighboring cell to be measured. For example, the terminal may determine all neighboring cells of the serving cell as the neighboring cells to be measured, and consider the reselection priority level of the neighboring cell.

In an embodiment, the neighbor cells to be measured determined by the terminal may include at least one neighbor cell whose network selection priority is not higher than that of the serving cell.

In one embodiment, after determining the neighbor cells to be measured, the terminal may perform measurement to determine the signal reception quality for each neighbor cell. For example, the terminal may receive the reference signal sent by the neighboring cell, and thus the reception quality of the terminal receiving the reference signal is taken as the signal reception quality of the terminal for the neighboring cell.

In one embodiment, the signal reception quality for the terminal for the neighbor cell may comprise at least one of a reference signal received power, RSRP, and a signal to noise ratio, SNR.

Step S102: if the neighbor cells with the signal quality meeting the preset conditions exist in the at least one neighbor cell, determining a target neighbor cell from the neighbor cells meeting the preset conditions, and switching to the target neighbor cell from the serving cell.

In an embodiment, after determining the signal reception quality of each neighboring cell, the terminal may detect the signal reception quality of each neighboring cell to determine whether there is a neighboring cell that meets a preset condition.

In an embodiment, if there are neighboring cells that meet the preset condition, the terminal may further perform screening to determine a target neighboring cell.

For example, if there are multiple neighboring cells that satisfy the preset condition, the terminal may determine, as the target neighboring cell, a neighboring cell with the highest signal reception quality in the neighboring cells that satisfy the preset condition.

It should be noted that the signal reception quality may include different parameters, corresponding preset conditions, and different manners for determining the target neighboring cell with the highest signal reception quality, which are described in detail below and are not described herein again.

In one embodiment, the terminal may attempt handover from the serving cell to the target neighbor cell after determining the target neighbor cell. Here, the handover may refer to "cell handover", or "cell reselection" in the related art, and the present embodiment is not limited thereto.

In one embodiment, the terminal may disconnect from the serving cell before attempting to access the target neighbor cell; alternatively, the terminal may attempt to access the target neighboring cell first and disconnect the connection with the serving cell after the connection is established.

According to the embodiment shown in fig. 1, when the terminal performs cell measurement, the terminal is not limited to only reselecting a neighboring cell with a higher priority than a current serving cell, but also measures a neighboring cell with a lower network selection priority, so that the terminal can select a target neighboring cell to be switched according to signal reception quality, the signal reception quality of the terminal in the target neighboring cell meets a preset condition, poor communication quality when the terminal resides in the high priority cell is avoided, and user experience is improved.

In one embodiment, the preset conditions include: the signal receiving quality of the terminal to the adjacent cell is higher than a first threshold value, and the difference between the signal receiving quality and the first threshold value is larger than a second threshold value.

In one embodiment, the first threshold may be predetermined. Optionally, the same first threshold may be set for different cell reselection priorities; alternatively, different first thresholds may be set for different cell reselection priorities, for example, the first threshold is inversely related to the cell reselection priority, i.e., the higher the cell reselection priority, the lower the set first threshold.

In an embodiment, the first threshold may also be a signal reception quality of the terminal for the current serving cell, for example, when the terminal measures the neighboring cell, the terminal may also measure the signal reception quality of the current serving cell, and use the measured signal reception quality of the terminal for the serving cell as the first threshold.

In one embodiment, the second threshold may be predetermined, and may be greater than 0 or equal to 0, for example. Optionally, the same second threshold may be set for different cell reselection priorities; alternatively, different second thresholds may be set for different cell reselection priorities, for example, the second threshold is inversely related to the cell reselection priority, i.e., the higher the cell reselection priority, the lower the set second threshold.

In an embodiment, if the first threshold is the signal reception quality of the terminal for the current serving cell, and the second threshold is negatively related to the cell reselection priority, after the terminal completes measurement on the neighboring cells, the terminal may respectively determine the reselection priority of each neighboring cell, so as to determine the second threshold corresponding to the reselection priority.

Based on this, in one embodiment, for each neighboring cell, the terminal may determine whether the signal reception quality of the neighboring cell is higher than a first threshold (i.e., the signal reception quality of the terminal for the current serving cell), and if not, determine that the neighboring cell does not satisfy the preset condition; if the difference between the signal reception quality and the first threshold is higher than the first threshold, further determining whether the difference between the signal reception quality and the first threshold is greater than a second threshold (i.e., a second threshold corresponding to the reselection priority of the neighboring cell), if the difference is greater than the second threshold, determining that the neighboring cell satisfies a preset condition, and if the difference is not greater than the second threshold, determining that the neighboring cell does not satisfy the preset condition.

In one embodiment, the signal reception quality comprises at least one of RSRP and SNR. The following description is made with reference to three different cases, respectively.

In the first case, the signal reception quality comprises RSRP.

In one embodiment, the first threshold may include an RSRP threshold, which may be, for example, a preset RSRP value or an RSRP received by the terminal on a signal of the current serving cell; the second threshold may comprise an RSRP difference threshold.

In one embodiment, the preset conditions may include: the RSRP of the signal reception of the adjacent cell by the terminal is higher than the RSRP threshold value, and the difference between the RSRP of the signal reception of the adjacent cell and the RSRP threshold value is larger than the RSRP difference threshold value.

For each neighboring cell which completes measurement, the terminal can judge the RSRP received by the signal of the neighboring cell, and if the RSRP is not higher than the RSRP threshold value, the neighboring cell is determined not to meet the preset condition; if the RSRP is higher than the RSRP threshold, further determining a difference value between the RSRP and the RSRP threshold, if the difference value is larger than the RSRP difference threshold, determining that the adjacent cell meets a preset condition, and if the difference value is not larger than the RSRP difference threshold, determining that the adjacent cell does not meet the preset condition.

In the second case, the signal reception quality includes SNR.

In one embodiment, the first threshold may include an SNR threshold, which may be, for example, a preset SNR value or an SNR received by the terminal for a signal of the current serving cell; the second threshold may comprise an SNR difference threshold.

In one embodiment, the preset conditions may include: the SNR of the signal reception of the neighbor cell by the terminal is higher than the SNR threshold, and the difference between the SNR of the signal reception of the neighbor cell and the SNR threshold is larger than the SNR difference threshold.

For each adjacent cell which completes measurement, the terminal can judge the SNR of the signal reception of the adjacent cell, and if the SNR is not higher than the SNR threshold, the adjacent cell is determined not to meet the preset condition; if the SNR is higher than the SNR threshold, further determining a difference value between the SNR and the SNR threshold, if the difference value is larger than the SNR difference threshold, determining that the adjacent cell meets a preset condition, and if the difference value is not larger than the SNR difference threshold, determining that the adjacent cell does not meet the preset condition.

In a third case, the signal reception quality includes RSRP and SNR.

In one embodiment, the first threshold comprises an RSRP threshold and an SNR threshold; the second threshold comprises an RSRP difference threshold and an SNR difference threshold.

In one embodiment, the preset conditions may include: the RSRP of the signal reception of the adjacent cell by the terminal is higher than the RSRP threshold value, and the difference between the RSRP of the signal reception of the adjacent cell and the RSRP threshold value is larger than the RSRP difference threshold value; and the SNR of the signal reception of the adjacent cell by the terminal is higher than the SNR threshold value, and the difference between the SNR of the signal reception of the adjacent cell and the SNR threshold value is larger than the SNR difference threshold value.

For each neighboring cell that completes measurement, the terminal may detect RSRP and SNR of signal reception of the cell, respectively.

For RSRP, firstly detecting whether the RSRP is higher than an RSRP threshold value, and if the RSRP is not higher than the RSRP threshold value, determining that the neighboring cell does not meet a preset condition; if the RSRP is higher than the RSRP threshold, further determining a difference value between the RSRP and the RSRP threshold, and if the difference value is larger than the RSRP difference threshold, determining that the neighboring cell meets the condition of the RSRP; and if the difference is not greater than the RSRP difference threshold, determining that the adjacent cell does not meet the preset condition.

For the SNR, firstly detecting whether the SNR is higher than an SNR threshold, and if the SNR is not higher than the SNR threshold, determining that the adjacent cell does not meet a preset condition; if the SNR is higher than the SNR threshold, further determining the difference value between the SNR and the SNR threshold, and if the difference value is larger than the SNR difference threshold, determining that the adjacent cell meets the SNR condition; and if the difference is not larger than the SNR difference threshold, determining that the adjacent cell does not meet the preset condition.

Therefore, if the terminal determines that the neighboring cell simultaneously satisfies the SNR condition and the RSRP condition, it may be determined that the neighboring cell satisfies the predetermined condition.

In the above embodiment, the terminal may perform screening jointly based on the SNR and RSRP received by the terminal for the adjacent cells, so that the determined adjacent cell meeting the preset condition is an adjacent cell with higher signal receiving quality of the terminal, and therefore, the target adjacent cell determined from the adjacent cells meeting the preset condition may also meet the requirement of the terminal for communication quality, so that the terminal has higher communication quality and better user experience after being switched to the target adjacent cell.

In one embodiment, the terminal may determine a weight α of RSRP and a weight β of SNR, respectively, with signal received quality = α × RSRP + β SNR. The weight may be set in advance, for example, α and β are both 50%, or α =60%, β =40%, or the like, and the weight may be determined according to actual conditions, which is not limited in this embodiment.

Optionally, the terminal may further introduce one or more other parameters to determine the signal reception quality, for example, one other parameter is introduced, for example, the other parameter may be denoted as X, and the corresponding weight is γ, so that the signal reception quality = α × RSRP + β × SNR + γ × X.

In one embodiment, the first threshold and the second threshold may both be predetermined. For example, when determining the first threshold, the RSRP threshold and the SNR threshold may be determined first, and then the weighted sum of the RSRP threshold and the SNR threshold may be used as the first threshold. Alternatively, the signal reception quality of the serving cell may be used as the first threshold, and for example, the terminal may calculate a weighted sum of RSRP and SNR of the received signal of the serving cell, and use the weighted sum as the first threshold.

In one embodiment, the terminal may calculate a weighted sum of RSRP and SNR of signal reception of the neighbor cell as the signal reception quality for the neighbor cell. Based on this, in one embodiment, the preset conditions include: the weighted sum of the RSRP and the SNR received by the terminal on the signals of the adjacent cells is higher than a first threshold value, and the difference between the RSRP and the SNR of the signal of the adjacent cells is larger than a second threshold value.

For each neighboring cell which completes measurement, the terminal may calculate, based on RSRP and SNR of signal reception of the neighboring cell, whether a weighted sum of RSRP and SNR of a received signal of the neighboring cell is higher than a first threshold, and if the weighted sum is higher than the first threshold, determine that the neighboring cell does not satisfy a preset condition; if the difference value is greater than the second threshold value, the adjacent cell is determined to meet the preset condition.

According to the embodiment, the terminal can determine the quality of the signal received by the terminal to the adjacent cell by calculating the weighted sum, and the screening of the adjacent cell is realized by a simple method.

In an embodiment, after the terminal determines the neighboring cell meeting the preset condition by the above method, the terminal may further determine a target neighboring cell therefrom. For example, the terminal may determine, as the target neighbor cell, a neighbor cell with the highest signal reception quality among the neighbor cells satisfying the preset condition.

For example, if the signal reception quality is determined according to the RSRP of the received signal, the terminal may determine the neighboring cell corresponding to the highest RSRP value as the target neighboring cell.

If the signal reception quality is determined according to the SNR of the received signal, the terminal may determine the neighbor cell corresponding to the highest SNR value as the target neighbor cell.

If the signal reception quality is determined according to the weighted sum of the RSRP and the SNR of the received signal, the terminal may determine the neighboring cell corresponding to the highest weighted sum as the target neighboring cell, and the method for determining the weighted sum may refer to the embodiment corresponding to the third scenario, which is not described herein again.

It should be noted that, the step of determining, by the terminal, the neighboring cell that satisfies the preset condition is different from the step of determining the target neighboring cell, that is, the method for determining, by the terminal, the signal reception quality when determining that satisfies the preset condition may be the same as or different from the method for determining, by the terminal, the signal reception quality when determining that the target neighboring cell is, and this embodiment is not limited.
