Background technique

A wireless communication network such as a 5th generation mobile communication technology (5G) network uses a cell as a smallest service unit. The wireless communication network usually configures other cells around a certain serving cell as neighboring cells of the cell, and broadcasts to user equipment (user equipment, UE) through a wireless communication system message. When the UE is transmitting data or services, such as during a call, the UE measures the signal quality of the serving cell and neighboring cells, and reports it 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 handover the UE to another suitable cell to ensure the communication quality of the UE.

However, the radio frequency performance of different types of UEs is quite different, which may lead to great differences in the service performance of different UEs on the same network (for example, at the same test point in the same cell, the signal quality detected by different UEs is very different). Moreover, different services have different requirements on the network side. For example, for voice services, in addition to the signal quality on the network side affecting service perception, packet loss, jitter, and transmission delay will also affect the mean opinion score (MOS) of voice service call quality. ) value; that is, under different network environments, the service perception that can be guaranteed is different, and each service has its own network requirements.

The cell handover method provided by the embodiment of the present invention can be applied to a communication system. Fig. 1 shows a schematic structural diagram of the communication system. As shown in FIG. 1 , a communication system 10 includes a user equipment 101 and a serving base station 102 . A user equipment 101 is connected to a serving base station 102 . The user equipment 101 and the serving base station 102 may be connected in a wired manner or in a wireless manner, which is not limited in this embodiment of the present invention.

The user equipment 101 may be a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (PDA), a wireless communication function Handheld devices, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks, etc.

Fig. 2 is a schematic flowchart of a cell handover method according to some exemplary embodiments. In some embodiments, the above cell handover method can be applied to the UE as shown in FIG. 1 or other similar devices.

As shown in Fig. 2, the cell handover method provided by the embodiment of the present invention includes the following S201-S206.

S201. The UE acquires at least one service quality indicator of a current service of the UE.

As a possible implementation manner, after establishing the current service, the UE acquires at least one service quality indicator corresponding to the current service according to a preset period.

It should be noted that the service quality index is used to reflect the level of service quality, one service may have multiple service quality indexes, and the number of service quality indexes of different services may be the same or different. For example, for a voice service, downlink channel quality indicator (channel quality indicator, CQI), downlink block error rate (block error rate, BLER), transmission delay may be set as service quality indicators of the service.

The preset period is pre-set in the UE by operation and maintenance personnel. For example, the preset period may be 128ms, which is not specifically limited in this embodiment of the present invention.

Exemplarily, after establishing the voice service, the UE acquires the CQI, BLER and transmission delay of the current voice service at a period of 128 ms.

S202. The UE judges whether the acquired service quality index is less than or equal to a corresponding first threshold.

As a possible implementation manner, the UE compares the obtained service quality indicator with a corresponding first threshold, and judges whether the service quality indicator is less than or equal to the corresponding first threshold.

It should be noted that the first threshold is pre-set in the UE by the operation and maintenance personnel, and one service quality indicator corresponds to one first threshold.

Exemplarily, the service quality indicators acquired by the UE are downlink CQI and downlink BLER; wherein, the first threshold corresponding to the downlink CQI is Threshold _CQI , and the first threshold corresponding to the downlink BLER is Threshold _BLER . The UE compares the downlink CQI with the Threshold _CQI to determine whether the downlink CQI is less than or equal to the Threshold _CQI ; and, the UE compares the downlink BLER to the Threshold _BLER to determine whether the downlink BLER is less than or equal to the Threshold _BLER .

S203. In a case where any service quality indicator is less than or equal to the corresponding first threshold, the UE determines a target neighboring cell from neighboring cells of the serving cell.

Wherein, the measured value of the signal quality of the target neighboring cell is greater than or equal to the second threshold corresponding to the current service.

As a possible implementation, when any service quality index is less than or equal to the corresponding first threshold, the UE obtains the measured value of the signal quality of the neighboring cell, and compares the obtained measured value of the signal quality of the neighboring cell with the current service Comparing the corresponding second threshold, judging 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; after that, the UE compares the neighboring cells whose signal quality is greater than or equal to the second threshold corresponding to the current service determined as the target neighbor cell.

It should be noted that the neighboring cells of the serving cell can be cells of the same frequency and/or the same system, or cells of different frequencies and/or different systems; the number of neighboring cells can be one or more, and the specific number is determined by the UE It depends on the network environment where it is located.

The measurement value of the signal quality of the neighboring cell can be reference signal receiving power (reference signal receiving power, RSRP), reference signal receiving quality (reference signal receiving quality, RSRQ), signal to interference plus noise ratio (signal to interference plus noise ratio, SINR) one or more of the . The specific measurement value is indicated by the serving base station of the UE. After the UE accesses the serving cell, the serving base station sends the measurement event type to the UE through a radio resource control (RRC) message, and the UE follows up the measurement required in the measurement event type. value to measure. For example, the type of measurement event delivered by the serving base station is based on RSRP, and the UE subsequently measures the RSRP of the serving cell and neighboring cells of the serving cell.

The second threshold is the minimum threshold of the signal quality of the serving cell required by the current service. Only when the signal quality of the serving cell is greater than or equal to the threshold, the service can be transmitted normally; the second threshold corresponding to different services can be the same or can be Differently, the second threshold can 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 offset of the current service.

Wherein, the target signal quality offset is negatively correlated with at least one service quality indicator.

As a possible implementation manner, the UE determines the size of the target signal quality offset of the previous service according to the size 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, the worse the current service quality is, and the larger the determined target signal quality offset is.

For the specific implementation manner of this step, reference may be made to the subsequent description of the embodiments of the present invention, and details are not repeated here.

S205. The UE determines the sum of the target signal quality offset and the signal quality of the target neighboring cell as the offset signal quality of the target neighboring cell.

Exemplarily, the measured value of the signal quality of the target adjacent cell is RSRP ₁ , and the signal quality offset is Δ ₁ , then the offset signal quality of the target adjacent cell RSRP ₂ =RSRP ₁ +Δ ₁ .

S206. The UE generates a measurement report including the offset signal quality.

As a possible implementation manner, the UE adds the offset signal quality of the target neighboring cell to the measurement report, so as to generate the measurement report including the offset signal quality.

It can be understood that the signal quality of the target neighboring cell in the measurement report is no longer the signal quality actually measured by the UE, but the offset signal quality after adding a signal quality offset. The offset signal quality is greater than the actual measured signal quality of the UE. received signal quality.

Correspondingly, after the UE generates the measurement report including the offset signal quality, it sends the measurement report to the serving base station of the UE.

In one design, adjacent cells include inter-frequency and/or inter-system cells. In order to obtain the measured value of the signal quality of adjacent cells, as shown in FIG. 3 and FIG. 4 , the cell handover method provided by the embodiment of the present invention further includes the following Describe S301.

S301. The UE sends a preset measurement report to the serving base station.

Wherein, the preset measurement report includes a preset value of the signal quality of the serving cell; the preset value is used to trigger the serving 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 different frequency and/or different system cells Signal quality.

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 the threshold value that triggers the base station to send the measurement target measurement control message. When the signal quality of the serving cell is less than or equal to the threshold value, the serving base station will instruct the UE to measure the signal quality of different frequency and/or different system cells .

Exemplarily, the third threshold is RSRP=-120dBm, and the UE sends a preset measurement report whose signal quality of the serving cell is RSRP=-128dBm to the serving base station; after receiving the measurement report, the serving base station will send the target measurement control to the UE message to instruct the UE to measure the signal quality of inter-frequency and/or inter-system cells.

In one design, in the cell handover method provided by the embodiment of the present invention, after determining that the UE establishes a 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 operation and maintenance personnel, for example, the preset sending period may be 256ms/512ms/1024ms and so on.

As another possible implementation manner, after determining that the UE establishes the current service, when any service quality indicator 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 by the embodiment of the present invention may specifically include the following S2041-S2043.

S2041. The UE determines the weight of each service quality indicator in at least one service quality indicator.

As a possible implementation manner, the UE queries the corresponding weight from a preset weight relationship table according to each service volume indicator.

It should be noted that the preset weight relationship table is preset by the operation and maintenance personnel in the UE; the preset weight relationship table includes the volume indicators of various services and the weights corresponding to each service volume indicator in each service.

S2042. The UE determines the target deviation degree of the current service according to at least one service quality indicator, the first threshold corresponding to each service quality indicator, and the weight of each service quality indicator.

Wherein, the target deviation degree is used to reflect the deviation degree of the service quality in the current service.

As a possible implementation, the UE substitutes at least one quality of service indicator, the first threshold corresponding to each quality of service indicator, and the weight of each quality of service indicator into the preset target deviation degree calculation formula to determine the target deviation.

It should be noted that the preset target deviation degree calculation formula is preset by the operation and maintenance personnel in UE; the preset target deviation degree calculation formula is: Wherein, Ω _ServingCell represents the degree of deviation from the target, Threshold _i represents the first threshold corresponding to the service quality index _i , and θ _i represents the weight of the service quality index _i .

S2043. According to the target deviation degree, the UE queries the target signal quality offset corresponding to the target deviation degree from the mapping relationship including the deviation degree and the signal quality offset.

It should be noted that the mapping relationship includes signal quality offsets corresponding to various deviation degrees; one deviation degree corresponds to one signal quality offset. After the UE determines the target deviation degree, it queries the deviation equal to the target deviation degree in the mapping relationship. degree to determine the target signal quality offset corresponding to the target deviation degree.

The technical solutions provided by the above embodiments bring at least the following beneficial effects: when the UE is performing service transmission, it continuously monitors the service quality indicators of the current service, and when any service quality indicator is less than or equal to the corresponding first threshold, the service from the service Determine the target neighboring cell that satisfies the conditions among the neighboring cells of the cell; after that, the UE adds a signal quality offset to the signal quality of the target neighboring cell, and reports it to the serving base station in the form of a measurement report, so that the serving base station sends the cell handover notification in advance Instructions allow the UE to switch to the target cell before the wireless environment of the serving cell deteriorates, so as to ensure that service perception is not affected.
