Description

Cell switching method, user equipment and storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell switching method, a user equipment, and a storage medium.
Background
A wireless communication network, such as a fifth generation mobile communication technology (5G) network, uses a cell as a minimum serving cell. A wireless communication network generally configures other cells around a serving cell as a neighboring cell of the cell, and broadcasts the neighboring cell to User Equipment (UE) through a wireless communication system message. When the UE performs data or service transmission, for example, during a call, the UE measures signal quality of a serving cell and a neighboring cell and reports the signal quality to the base station. When the signal reception strength or quality of the serving cell measured by the UE is poor to a certain threshold, the base station will usually switch the UE to another suitable cell to ensure the communication quality of the UE.
However, the UE radio frequency performance of different types of UEs is greatly different, which may cause the service performance of different UEs in the same network to be greatly different (for example, at the same test point in the same cell, the signal quality detected by different UEs is greatly different). For example, for a voice service, except that the signal quality of the network side affects service perception, packet loss, jitter, and transmission delay also affect a Mean Opinion Score (MOS) value of the speech service call quality; that is, under different network environments, the service awareness that can be guaranteed is different, and each service has its own network requirement.

Fig. 2 is a flow chart illustrating a cell handover method according to some example embodiments. In some embodiments, the above cell switching method may be applied to a UE as shown in fig. 1 or other similar devices.
As shown in fig. 2, a cell handover method provided in an embodiment of the present invention includes the following steps S201 to S206.
S201, UE obtains at least one service quality index of the current service of the UE.
As a possible implementation manner, after the UE establishes the current service, at least one service quality indicator corresponding to the current service is obtained according to a preset period.
It should be noted that the service quality indicator is used to reflect the quality of the service, one service may have multiple service quality indicators, and the number of the service quality indicators of different services may be the same or different. For example, for voice service, a downlink Channel Quality Indicator (CQI), a downlink block error rate (BLER), and a transmission delay may be used as service quality indicators of the service.
The preset period is preset in the UE by the operation and maintenance staff, for example, the preset period may be 128ms, and the embodiment of the present invention is not limited specifically herein.
Illustratively, after establishing the voice service, the UE acquires the CQI, BLER, and transmission delay of the current voice service according to a 128ms period.
S202, the UE judges whether the acquired service quality index is smaller than or equal to a corresponding first threshold value.
As a possible implementation manner, the UE compares the obtained service quality indicator with the corresponding first threshold, and determines whether the service quality indicator is less than or equal to the corresponding first threshold.
It should be noted that the first threshold is set in the UE in advance by the operation and maintenance staff, and one service quality index corresponds to one first threshold.
Exemplarily, the service quality indicators obtained by the UE are downlink CQI and downlink BLER; wherein, the first Threshold corresponding to the downlink CQI is ThresholdCQIThe first threshold corresponding to the downlink BLER is ThresholdBLER. UE sends downlink CQI and ThresholdCQIComparing, judging whether the downlink CQI is less than or equal to ThresholdCQI(ii) a And UE (user equipment) enables downlink BLER and ThresholdBLERComparing, judging whether the downlink BLER is less than or equal to ThresholdBLER。
S203, under the condition that any one service quality index is smaller than or equal to the corresponding first threshold value, the UE determines a target neighbor cell from neighbor cells of the service cell.
And the measured value of the signal quality of the target neighbor cell is greater than or equal to a second threshold corresponding to the current service.
As a possible implementation manner, under the condition that any one of the service quality indexes is less than or equal to the corresponding first threshold, the UE obtains the measured value of the signal quality of the neighboring cell, compares the obtained measured value of the signal quality of the neighboring cell with the second threshold corresponding to the current service, and determines whether the measured value of the signal quality of each neighboring cell is greater than or equal to the second threshold corresponding to the current service; and then, the UE determines the neighbor cell of which the measured value of the signal quality is greater than or equal to a second threshold corresponding to the current service as a target neighbor cell.
It should be noted that the neighboring cells of the serving cell may be cells of the same frequency and/or the same system, or cells of different frequency and/or different system; the number of the neighboring cells may be one or multiple, and the specific number is determined by the network environment where the UE is located.
The measured value of the signal quality of the neighboring cell may be one or more of Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), signal to interference plus noise ratio (SINR). The specific measurement value is indicated by a serving base station of the UE, and after the UE accesses the serving cell, the serving base station issues a measurement event type to the UE through a Radio Resource Control (RRC) message, and the UE follows the measurement value required in the measurement event type to perform measurement. For example, if the measurement event type issued by the serving base station is based on RSRP, the UE subsequently measures RSRP of the serving cell and RSRP of neighboring cells of the serving cell.
The second threshold is the lowest threshold of the signal quality of the serving cell required by the current service, and the service can be normally transmitted only when the signal quality of the serving cell is greater than or equal to the threshold; the second threshold values corresponding to different services may be the same or different, and the second threshold values may be preset in the UE by operation and maintenance personnel according to requirements of different services.
S204, the UE determines the target signal quality bias of the current service.
Wherein the target signal quality offset is inversely related to the at least one quality of service indicator.
As a possible implementation manner, the UE determines the magnitude of the target signal quality offset of the previous service according to the magnitude of the difference between the service quality indicator of the current service and the corresponding first threshold.
It can be understood that the smaller the service quality index of the current service is, the worse the current service quality is, the larger the determined target signal quality bias is.
The specific implementation manner of this step may refer to the following description of the embodiment of the present invention, and is not described herein again.
S205, the UE determines the sum of the target signal quality bias and the signal quality of the target adjacent cell as the bias signal quality of the target adjacent cell.
Illustratively, the target neighbor cell signal quality measurement is RSRP1The signal quality bias is delta1Then the bias signal quality RSRP of the target neighbor cell2＝RSRP1+△1。
S206, the UE generates a measurement report comprising the offset signal quality.
As a possible implementation, the UE adds the offset signal quality of the target neighbor cell to the measurement report to generate a measurement report including the offset signal quality.
It can be understood that, at this time, the signal quality of the measurement report about the target neighbor cell is not the signal quality actually measured by the UE, but is an offset signal quality with a signal quality offset added, and the offset signal quality is greater than the signal quality actually measured by the UE.
Accordingly, after the UE generates a measurement report including the offset signal quality, the measurement report is transmitted to a serving base station of the UE.
In one design, the neighboring cells include inter-frequency and/or inter-system cells, and in order to obtain the measured value of the signal quality of the neighboring cell, as shown in fig. 3 and 4, the cell handover method provided in the embodiment of the present invention further includes the following step S301.
S301, the UE sends a preset measurement report to a service base station.
The preset measurement report comprises a preset value of the signal quality of the serving cell; the preset value is used for triggering the service base station to send a target measurement control message to the UE; the target measurement control message is used to instruct the UE to measure the signal quality of the inter-frequency and/or inter-system cell.
It should be noted that the preset value of the signal quality of the serving cell is less than or equal to the third threshold. The third threshold is a threshold for triggering the base station to send a measurement control message of a target, and when the signal quality of the serving cell is less than or equal to the threshold, the serving base station will instruct the UE to measure the signal quality of the inter-frequency and/or inter-system cell.
Illustratively, the third threshold is RSRP-120 dBm, and the UE sends a preset measurement report with a serving cell signal quality of-128 dBm to the serving base station; after receiving the measurement report, the serving base station sends a target measurement control message to the UE to instruct the UE to measure the signal quality of the inter-frequency and/or inter-system cell.
In one design, in the cell handover method provided in the embodiment of the present invention, after determining that the UE establishes the current service, the UE sends a preset measurement report to the serving base station.
As a possible implementation manner, after determining that the UE establishes the current service, the UE sends a preset measurement report to the serving base station according to a preset sending period.
It should be noted that the preset sending period is preset in the UE by the operation and maintenance staff, for example, the preset sending period may be 256ms/512ms/1024 ms.
As another possible implementation manner, after determining that the UE establishes the current service, when any one of the service quality indicators is smaller than or equal to the corresponding first threshold, the UE sends a preset measurement report to the serving base station.
In one design, in order to determine the signal quality offset of the current service, as shown in fig. 5, the S204 provided in the embodiment of the present invention may specifically include the following S2041 to S2043.
S2041, UE determines the weight of each service quality index in at least one service quality index.
As a possible implementation manner, the UE queries the corresponding weight from a preset weight relation table according to each traffic index.
It should be noted that the preset weight relationship table is preset in the UE by the operation and maintenance staff; the preset weight relation table comprises the quantity indexes of various services and the weight corresponding to each service quantity index in each service.
S2042, the UE determines the target deviation degree of the current service according to at least one service quality index, the first threshold corresponding to each service quality index and the weight of each service quality index.
The target deviation degree is used for reflecting the deviation degree of the service quality in the current service.
As a possible implementation manner, the UE substitutes at least one service quality indicator, a first threshold corresponding to each service quality indicator, and a weight of each service quality indicator into a preset target deviation calculation formula to determine a target deviation of the current service.
It should be noted that the preset target deviation calculation formula is preset in the UE by the operation and maintenance staff; the preset target deviation calculation formula is as follows:

wherein omegaServingCellRepresents the degree of target departure, ThresholdiIndicating a quality of service indicatoriCorresponding first threshold value, thetaiIndicating a quality of service indicatoriThe weight of (c).
S2043, the UE inquires a target signal quality bias corresponding to the target deviation degree from a mapping relation comprising the deviation degree and the signal quality bias according to the target deviation degree.
It should be noted that the mapping relationship includes signal quality offsets corresponding to various deviation degrees; and after the UE determines the target deviation degree, inquiring the deviation degree equal to the target deviation degree in the mapping relation so as to determine the target signal quality bias corresponding to the target deviation degree.
The technical scheme provided by the embodiment at least has the following beneficial effects: when the UE transmits the service, the UE continuously monitors the service quality index of the current service, and determines a target neighbor cell meeting the condition from neighbor cells of the serving cell under the condition that any one service quality index is less than or equal to the corresponding first threshold; and then, the UE increases the signal quality bias on the signal quality of the target adjacent cell and reports the signal quality bias to the serving base station in the form of a measurement report, so that the serving base station issues a cell switching instruction in advance, and the UE can be switched to the target cell before the wireless environment of the serving cell deteriorates, thereby ensuring that the service perception is not influenced.
