It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Fig. 1 is a flow chart illustrating a method of cell handover according to some embodiments of the present disclosure.
As shown in fig. 1, the cell switching method includes steps S11 to S15. In some embodiments, the cell handover method is performed by the source base station.
In step S11, a measurement control instruction is transmitted to the terminal. The measurement control instruction includes a service identification. The measurement control instruction is used for instructing the terminal to measure the state of the service corresponding to the service identifier.
In some embodiments, the measurement control instruction further includes an RSRP (Reference Signal Receiving Power, reference signal received power) threshold value for the plurality of cell switching modes. The measurement control instruction is used for instructing the terminal to measure the RSRP of the service corresponding to the service identifier, and determining the state of the service corresponding to the service identifier by comparing the RSRP of the measured service with the RSRP threshold values of various cell switching modes.
In step S12, a measurement report from the terminal is received. The measurement report includes the service identity and the status of its corresponding service. In some embodiments, the status of the traffic includes a 5G quality of service identifier (5 QI).
In step S13, the service type of the service is determined according to the status of the service.
In some embodiments, the 5G quality of service (Quality of Service, qoS) characteristics corresponding thereto may be determined from the 5G quality of service identification; and judging the service type of the service according to the 5G service quality characteristics. For example, the 5G quality of service characteristics include latency (network latency) and packet error rate. The source base station stores a corresponding relation between the 5G quality of service identifier and the 5G quality of service characteristic, and can determine the 5G quality of service characteristic corresponding to the 5G quality of service identifier according to the corresponding relation.
In some embodiments, the service type of the service may be determined according to the 5G quality of service characteristics in the following manner.
And judging the service type of the service to be a time delay sensitive service under the condition that the time delay is less than or equal to a time delay threshold value.
And judging the service type of the service to be a high-reliability service under the condition that the time delay is larger than the time delay threshold value and the data packet error rate is smaller than or equal to the error rate threshold value.
And under the condition that the time delay is larger than the time delay threshold value and the data packet error rate is larger than the error rate threshold value, judging the service type of the service to be the conventional service. Conventional traffic here refers to traffic without special latency or reliability requirements.
In step S14, a target cell switching method suitable for the service type is determined from among a plurality of cell switching methods. In some embodiments, the multiple cell handover approaches include hard handover, CHO (Conditional Handover ) and DAPS (Dual Active Protocol Stack, dual active protocol stack) handover. The hard handoff is a traditional handoff method, specifically, when the terminal accesses the target base station, the data transmission with the source base station is stopped. And after the terminal receives the switching command, switching to the target base station indicated by the switching command immediately. When the terminal detects that one candidate target base station meets the corresponding switching execution condition, the terminal needs to send a measurement report to inform the source base station. In the DAPS handoff technique, a terminal maintains uplink or downlink data transmission with a source base station. In CHO technology, the terminal continuously determines whether the received handover execution condition is satisfied, and the terminal does not immediately execute the handover operation, and directly determines the handover.
In step S15, the control terminal performs handover to the target cell according to the determined target cell handover pattern.
In some embodiments, the control terminal may be implemented to switch to the target cell as follows.
First, a handover request message is sent to a target base station. The handover request message includes the determined target cell handover pattern.
Then, under the condition that the target base station supports the target cell switching mode, a switching response message which comprises terminal air interface configuration information for instructing the terminal to switch to the target cell by adopting the target cell switching mode is received from the target base station.
Finally, an RRC (Radio Resource Control ) reconfiguration message is sent to the terminal. The RRC reconfiguration message comprises terminal air interface configuration information so as to control the terminal to switch to the target cell according to the terminal air interface configuration information.
In the above embodiment, the terminal is instructed to measure the service state, and judge the service type according to the service state fed back by the terminal, and then select the cell switching mode according to the service type, so that the terminal can more accurately select the cell switching mode more suitable for the current service scene of the terminal according to the service state under the condition of supporting multiple cell switching modes at the same time, thereby improving the accuracy of cell switching, improving the network performance of the terminal side, and improving the user perception and user experience.
