These drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the inventive concepts to those skilled in the art by reference to specific embodiments.
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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
First, the terms involved are explained:
reference Signal Received Power (RSRP): linear averaging of the power of the reference signal received over a wide band characterizes the wireless signal strength;
reference Signal Receiving Quality (Reference Signal Receiving Quality, RSRQ): a ratio of reference signal received power to received signal strength indication.
Fig. 1 is a schematic view of an application scenario of a cell switching method according to an embodiment of the present application. Exemplified in connection with the illustrated scenario: when the base station receives a cell switching request of the user terminal, the user perception rate of the user terminal in the target cell is obtained based on the pre-established user perception rates corresponding to different signal qualities in each cell according to the signal quality of the user terminal in the target cell. And comparing the user perception rate of the user terminal in the target cell with the user perception rate of the user terminal in the current cell, and if the user perception rate of the user terminal in the target cell is not less than the user perception rate of the user terminal in the current cell, indicating that the user perception rate can be improved by switching to the target cell, executing cell switching. If the user perception rate of the user terminal in the target cell is less than the user perception rate of the user terminal in the current cell, the switching to the target cell cannot improve the user perception rate, even the user perception rate is reduced, and then the cell switching is not executed.
In the related art, the cell handover is based only on the signal quality, which does not completely reflect the user perception level, and thus the cell handover cannot be performed in an ideal state.
The following describes an example of the embodiments of the present application with reference to the following embodiments.
Example one
Fig. 2 is a schematic flowchart of a cell handover method according to an embodiment of the present application, where the method includes the following steps:
s101, receiving a switching request sent by a user terminal, wherein the switching request comprises a user perception rate of the user terminal in a current cell and signal quality of the user terminal in a target cell;
s102, obtaining user perception rates of the user terminal in a target cell based on pre-established user perception rates corresponding to different signal qualities in each cell according to the signal quality of the user terminal in the target cell;
s103, if the user perception rate of the user terminal in the target cell is not less than the user perception rate of the user terminal in the current cell, switching the user terminal to the target cell; and if the user perception rate of the user terminal in the target cell is less than the user perception rate of the user terminal in the current cell, not executing switching.
As an example, the execution subject of the embodiment may be a cell switching apparatus, and the cell switching apparatus is implemented in various ways. For example, the program may be software, or a medium storing a related computer program, such as a usb disk; alternatively, the apparatus may also be a physical device, such as a chip, an intelligent terminal, a computer, a server, etc., integrated with or installed with the relevant computer program. In practical application, the cell switching device may be separately installed or may be integrally installed in the base station.
In one example, the handover request is sent after the ue monitors that the signal quality of the current cell and the signal quality of the neighboring cell satisfy the cell handover condition.
Combining a scene example: the user terminal judges whether to send out a switching request according to the signal quality of the user terminal in the current cell and the signal quality of the user terminal in the adjacent cell; for example, the cell handover condition may be set to determine that a handover request needs to be issued when the signal quality of the ue in the neighboring cell is better than the signal quality of the ue in the current cell. And if the switching request is judged to be sent, the adjacent cell is the target cell. For example, if the signal quality of the ue in the current cell is smaller than that of the neighboring cell and the difference value exceeds the preset first threshold, it indicates that the signal quality of the neighboring cell is significantly higher than that of the current cell, and the neighboring cell is used as a handover target cell to send a handover request to the base station.
Based on the above embodiment, it can be determined whether to issue a handover request, which provides a basis for determining whether to execute a handover request next. It should be noted that, the scenario for initiating the cell handover request in practical applications includes, but is not limited to, the above-mentioned cases, which are not illustrated here.
In one example, S102 specifically includes: determining a first signal quality which has a difference with the signal quality of the user terminal in a target cell which does not exceed a predetermined error range; obtaining a first user perception rate corresponding to the first signal quality based on user perception rates corresponding to different signal qualities in the cells; and calculating the average value of the first user perception rate as the user perception rate of the user terminal in the target cell.
For example, assuming that the predetermined error range is 3dB, the signal quality within ± 3dB from the signal quality of the user terminal in the target cell is selected as the first signal quality. And obtaining first user perception rates respectively corresponding to the first signal qualities based on the user perception rates corresponding to the different signal qualities in each cell. And calculating the average value of all the first user perception rates as the predicted user perception rate of the user terminal in the target cell.
Based on the above embodiment, the perception level of the user can be directly embodied by using the user perception rate as the cell switching basis in a manner of corresponding the signal quality to the user perception rate. The predicted user perception rate of the user terminal in the target cell is obtained by calculating the average value, and the error influence can be reduced.
In one example, the cell switching method further includes: aiming at each cell, acquiring the signal quality and the user perception rate of each user terminal under the cell according to a preset time interval; and establishing user perception rates corresponding to different signal qualities in each cell according to the signal quality and the user perception rate of each user terminal in each cell.

And respectively establishing user perception rates corresponding to different signal qualities for each cell. And acquiring the signal quality of all users in the current cell and the corresponding user perception rate in the current cell. And if the signal quality of a plurality of users is the same, calculating the average value of the user perception rates corresponding to the users as the user perception rate corresponding to the signal quality. For example, for cell 1, cell 2, cell 3, etc., each cell has user a, user B, user C, etc., and user a, user B, and user C of cell 1 have respective signal qualities and corresponding user perception rates, respectively. If the signal quality of the user A and the signal quality of the user B in the cell 1 are the same, calculating the average value of the user perception rates of the user A and the user B as the user perception rate corresponding to the signal quality.
Based on the above embodiment, the corresponding relation between the signal quality and the user perception rate is established by obtaining the signal quality and the user perception rate of the user in the cell, so as to provide a basis for calculating the user perception rate of the user terminal in the target cell.
In one example, the user-perceived rate includes a user-perceived uplink rate and a user-perceived downlink rate, and the cell switching method further includes: acquiring uplink flow and downlink flow of a user terminal in a current cell within a certain time; the obtaining the user perception rate of the user terminal in the target cell based on the pre-established user perception rates corresponding to different signal qualities in each cell according to the signal quality of the user terminal in the target cell includes: if the uplink flow is smaller than the downlink flow, obtaining the user perception rate of the user terminal in a target cell based on user perception downlink rates corresponding to different signal qualities in the target cell according to the signal quality of the user terminal in the target cell; and if the uplink flow is greater than the downlink flow, obtaining the user perception rate of the user terminal in the target cell based on the user perception uplink rates corresponding to different signal qualities in the target cell according to the signal quality of the user terminal in the target cell.
In combination with the scenario example, the user sensing rate includes a user sensing uplink rate and a user sensing downlink rate, which respectively reflect uplink service and downlink service, the service emphasis directions of different users are different, and when a cell is switched, the main service of the user should be considered. And respectively establishing corresponding relations between the user perception uplink rate and the user perception downlink rate when establishing the user perception rates corresponding to different signal qualities. If the downlink flow of the user is redundant and the uplink flow of the user is redundant within a certain time, which indicates that the user mainly uses the uplink service, the user perception uplink rate should be calculated when the user perception rate is calculated, and whether the cell switching is carried out can be correctly guided.
Based on the above embodiment, the user perception rate calculation can be provided for the user with different service emphasis pertinently by distinguishing the uplink rate and the downlink rate to calculate the user perception rate, and the prediction result is more accurate.
In one example, the signal quality includes a reference signal received power or a reference signal received quality.
In combination with the scenario example, the reference signal received power reflects the coverage strength of the signal, and the reference signal received quality reflects the signal-to-noise ratio and the interference level of the signal. In practical application, the corresponding signal quality is selected as the basis for cell switching according to a specific application scenario.
In the cell switching method provided in this embodiment, a switching request sent by a user terminal is received, where the switching request includes a user perception rate of the user terminal in a current cell and a signal quality of the user terminal in a target cell; according to the signal quality of the user terminal in the target cell, based on the pre-established user perception rates corresponding to different signal qualities in each cell, obtaining the user perception rate of the user terminal in the target cell; if the user perception rate of the user terminal in the target cell is not less than the user perception rate of the user terminal in the current cell, switching the user terminal to the target cell; and if the user perception rate of the user terminal in the target cell is less than the user perception rate of the user terminal in the current cell, not executing switching. According to the scheme, the signal quality is corresponding to the user perception rate, and the user perception rate is added into the consideration factor of cell switching, so that the stability of the user perception level is ensured, and the reliability of cell switching is ensured.

And if the switching request is judged to be sent, the adjacent cell is the target cell. For example, if the signal quality of the ue in the current cell is less than that of the neighboring cell and the difference value exceeds the preset first threshold, it indicates that the signal quality of the neighboring cell is significantly better than that of the current cell, and the neighboring cell is used as the handover target cell to send a handover request to the base station.
Based on the above embodiment, it can be determined whether to issue a handover request, which provides a basis for determining whether to execute a handover request next.
