Description
Technical Field

Background
Wireless communication networks, such as fifth generation mobile communication technology (5th generation mobile communication technology,5G) networks, are cell-minimum service units. The wireless communication network typically configures other cells surrounding a certain serving cell as neighbors of the cell and broadcasts via wireless communication system messages to User Equipment (UE). 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 receiving strength or quality of the serving cell measured by the UE is poor to a certain threshold value, the base station will typically switch the UE to another suitable cell to ensure the communication quality of the UE.
However, the radio frequency performance of UEs of different models may be different, which may result in a large difference in service performance of different UEs under the same network (e.g., the same test point in the same cell, and the signal quality detected by different UEs is very different). For example, for voice service, besides the influence of signal quality on service perception on network side, packet loss, jitter and transmission delay also have influence on voice service call quality average opinion (mean opinion score, MOS) value; namely, under different network environments, the guaranteed service perceptions are different, and each service has respective network requirements.

Fig. 2 is a flow chart diagram illustrating a method of cell handover according to some example embodiments. In some embodiments, the above-described cell handover method may be applied to a UE or other similar device as shown in fig. 1.
As shown in fig. 2, the cell handover method provided in the embodiment of the present invention includes the following steps S201 to S206.
S201, the UE acquires 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 quality of service index is used to reflect the quality of service, one service may have multiple quality of service indexes, and the number of quality of service indexes of different services may be the same or different. For example, for voice traffic, a downlink channel quality indicator (channel quality indicator, CQI), a downlink error rate (BLER), and a transmission delay may be set as the traffic quality indicator for the traffic.
The preset period is preset in the UE by the operator, for example, the preset period may be 128ms, which is not specifically limited herein.
Illustratively, after establishing the voice service, the UE acquires CQI, BLER, and transmission delay of the current voice service in a period of 128 ms.
S202, the UE judges whether the acquired service quality index is smaller than or equal to a corresponding first threshold value.
As one possible implementation manner, the UE compares the acquired quality of service indicator with a corresponding first threshold value, and determines whether the quality of service indicator is less than or equal to the corresponding first threshold value.
It should be noted that, the first threshold is preset in the UE by the operator, and one service quality index corresponds to one first threshold.
Exemplary, the quality of service index obtained by the UE is downlink CQI and downlink BLER; wherein the first Threshold corresponding to the downlink CQI is Threshold CQI The first Threshold corresponding to the downlink BLER is Threshold BLER . The UE transmits downlink CQI and Threshold CQI Comparing, judging whether the downlink CQI is less than or equal to Threshold CQI The method comprises the steps of carrying out a first treatment on the surface of the And the UE transmits the downlink BLER and Threshold BLER Comparing, judging whether the downlink BLER is less than or equal to Threshold BLER 。
And S203, under the condition that any service quality index is smaller than or equal to a corresponding first threshold value, the UE determines a target neighbor cell from neighbor cells of the serving cell.
And the measured value of the signal quality of the target neighbor cell is larger than or equal to a second threshold value corresponding to the current service.
As a possible implementation manner, under the condition that any one service quality index is smaller than or equal to a corresponding first threshold value, the UE acquires a measured value of signal quality of a neighboring cell, compares the acquired measured value of signal quality of the neighboring cell with a second threshold value corresponding to the current service, and judges whether the measured value of signal quality of each neighboring cell is larger than or equal to the second threshold value corresponding to the current service; and then, the UE determines the neighbor cell with the measured value of the signal quality larger than or equal to a second threshold corresponding to the current service as a target neighbor cell.
The neighbor cells of the serving cell may be the same-frequency and/or same-system cells, or may be different-frequency and/or different-system cells; the number of the neighbor cells can be one or a plurality of neighbor cells, and the specific number is determined by the network environment where the UE is located.
The measure of neighbor cell signal quality may be one or more of reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), signal to interference plus noise ratio (signal to interference plus noise ratio, SINR). The specific measured value is indicated by the 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 (radio resource control, RRC) message, and the UE follows the measured value required in the measurement event type to perform measurement. For example, the measurement event type issued by the serving base station is RSRP-based, and the UE subsequently measures RSRP of the serving cell and neighboring cells of the serving cell.
The second threshold is the lowest threshold of the signal quality of the service cell required by the current service, and the service can be normally transmitted only when the signal quality of the service cell is greater than or equal to the threshold; the second thresholds corresponding to different services may be the same or different, and the second thresholds may be preset in the UE by the operation and maintenance personnel according to the 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 size of the target signal quality offset of the pre-service according to the size of the difference between the quality of service index of the current service and the corresponding first threshold.
It can be appreciated that the smaller the quality of service indicator of the current service, the worse the current quality of service, the greater the determined target signal quality offset.
The specific implementation of this step may refer to the following description of the embodiment of the present invention, and will not be described herein.
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.
Exemplary, the target neighbor cell signal quality measurement is RSRP 1 Signal quality offset is delta 1 The bias signal quality RSRP of the target neighbor cell 2 ＝RSRP 1 +△ 1 。
S206, the UE generates a measurement report including the bias signal quality.
As one possible implementation, the UE adds the bias signal quality of the target neighbor cell to the measurement report to generate a measurement report including the bias signal quality.
It can be appreciated that the signal quality of the target neighbor cell in the measurement report is not the signal quality actually measured by the UE, but an offset signal quality after the signal quality offset is 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 the serving base station of the UE.
In one design, the neighboring cells include inter-frequency and/or inter-system cells, and in order to be able to obtain the measured value of the signal quality of the neighboring cells, as shown in fig. 3 and fig. 4, the cell switching method provided by the embodiment of the present invention further includes the following S301.
S301, the UE sends a preset measurement report to the service base station.
Wherein 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 inter-frequency and/or inter-system cells.
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 issue a measurement target measurement control message, and when the signal quality of the serving cell is smaller than or equal to the threshold, the serving base station indicates the UE to measure the signal quality of the inter-frequency and/or inter-system cell.
For example, the third threshold is rsrp= -120dBm, and the ue sends a preset measurement report with the serving cell signal quality rsrp= -128dBm 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, 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 transmits a preset measurement report to the serving base station according to a preset transmission period.
It should be noted that, the preset transmission period is preset in the UE by the operator, for example, the preset transmission period may be 256ms/512ms/1024ms, etc.
As another possible implementation manner, after determining that the UE establishes the current service, when any one of the quality of service indexes is less 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 above S204 provided in the embodiment of the present invention may specifically include the following S2041-S2043.
S2041, the UE determines a weight for each of the at least one quality of service indicator.
As a possible implementation manner, the UE queries the corresponding weight from the preset weight relation table according to each traffic index.
The preset weight relation table is preset in the UE by an operation and maintenance personnel; the preset weight relation table comprises the quantity indexes of various services and the weights corresponding to the quantity indexes of the various services in each service.
S2042, the UE determines the target deviation degree of the current service according to at least one service quality index, a 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 index, a first threshold corresponding to each service quality index, and a weight of each service quality index into a preset target deviation calculation formula, so as to determine a target deviation of the current service.
The preset target deviation degree calculation formula is preset in the UE by an operation and maintenance personnel; the preset target deviation calculation formula is as follows:wherein Ω ServingCell Representing the degree of deviation of the target, threshold i Indicating quality of service indicators i Corresponding first threshold value, θ i Indicating quality of service indicators i Is a weight of (2).
And S2043, the UE queries the target signal quality offset corresponding to the target deviation degree from the mapping relation comprising the deviation degree and the signal quality offset according to the target deviation degree.
The mapping relation includes signal quality bias corresponding to various deviation degrees; and after determining the target deviation degree, the UE queries the deviation degree equal to the target deviation degree in the mapping relation to determine the target signal quality bias corresponding to the target deviation degree.
The technical scheme provided by the embodiment at least brings the following beneficial effects: when the UE transmits the service, continuously monitoring the service quality index of the current service, and determining a target neighbor cell meeting the condition from neighbor cells of the service cell under the condition that any one of the service quality indexes is smaller than or equal to a corresponding first threshold value; and then, the UE increases the signal quality bias on the signal quality of the target neighbor cell and reports the signal quality bias to the service base station in the form of a measurement report, so that the service 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 service cell is deteriorated, so that the service perception is not influenced.
