Detailed Description
The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inventor researches and discovers that the parameter configuration of the cell base station and the cell switching execution are continuous in the traditional cell switching process. However, there is a time interval between the parameter configuration of the cell base station in the conditional handover and the cell handover execution process, and when the radio configuration parameters of the source cell and the candidate cell are updated, the conditional handover configuration parameters are updated accordingly. If the conditional handover configuration parameters are not updated, the robustness of cell handover will be reduced. The patent provides parameter configuration aiming at the problem that time interval exists between parameter configuration of a cell base station in condition switching and the process of executing switching, and the parameter configuration is used for updating the condition switching configuration parameters of a terminal after the wireless configuration parameters of a source cell and a candidate cell are updated.
Some embodiments of the parameter configuration method of the present disclosure are first described in conjunction with fig. 1.
Fig. 1 shows a flow diagram of a parameter configuration method of some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S101 to S103.
In step S101, the base station detects that the conditional handover configuration parameter is updated.
The configuration of the core network or the access network changes (for example, qoS flow addition or deletion, radio resource allocation, and the like), and the conditional handover configuration parameters of the terminal need to be updated. The conditional access configuration parameters generally include radio configuration parameters and conditional access execution conditions on the base station side. The radio configuration parameters at the base station side may include radio configuration parameters of the source cell base station or radio configuration parameters of the candidate cell base station, and these radio configuration parameters may specifically be parameters, measurement configuration parameters, random access configuration parameters, and the like corresponding to each radio bearer allocated by the cell base station to the terminal. The conditional handover performing condition may be, for example, determining that the signal quality of the candidate cell base station is higher than that of the source cell by a predetermined offset amount, or the like.
In step S102, the base station transmits the updated conditional handover configuration parameters to the terminal.
The base station sends the updated conditional switch configuration parameters to the terminal, and can instruct the terminal to detect whether the updated conditional switch configuration parameters are supported.
In step S103, the base station receives a conditional handover configuration parameter update response sent by the terminal, so as to determine whether the conditional handover configuration parameter update is completed according to the conditional handover configuration parameter update response.
The embodiment can update the conditional switch configuration parameters in real time and verify whether the terminal supports the updated conditional switch configuration parameters, thereby improving the robustness of cell switching.
Two specific cases that the source cell base station detects that the conditional handover configuration parameter is updated in step S101 are described below.
(case a) the source cell triggers a conditional handover configuration parameter update. In case a, step S101 specifically includes:
in step S1011A, the source cell base station updates the radio configuration parameter of the source cell base station, and sends the radio configuration parameter updated by the source cell base station to the candidate cell base station.
Step S1012A, the candidate cell base station updates the radio configuration parameters and the conditional handover execution conditions of the candidate cell base station according to the radio configuration parameters updated by the source cell base station, and generates updated conditional handover configuration parameters.
The updated conditional handover configuration parameters comprise updated radio configuration parameters of the source cell base station, updated radio configuration parameters of the candidate cell base station and updated conditional handover execution conditions.
In step S1013A, the source cell base station receives the updated conditional handover configuration parameters sent by the candidate cell base station, so as to pass through to the terminal.
(case B) the candidate cell triggers a conditional handover configuration parameter update. In case B, step S101 specifically includes:
step S1011B, the candidate cell base station updates the wireless configuration parameters and the conditional switch execution conditions of the candidate cell base station and generates updated conditional switch configuration parameters, and the updated conditional switch configuration parameters comprise the updated wireless configuration parameters and the updated conditional switch execution conditions of the candidate cell base station;
step S1012B, the source cell base station receives the updated conditional handover configuration parameters sent by the candidate cell base station, so as to pass through to the terminal.
In the above two cases, before the terminal does not complete the cell handover, the source cell may flexibly configure the conditional handover configuration parameter of the terminal, thereby implementing real-time update of the radio configuration parameter of the source cell, the radio configuration parameter of the candidate cell, and the conditional handover execution condition, and ensuring that the conditional handover is performed based on the latest radio configuration parameter of the cell base station.
An application example of the parameter configuration method of the present disclosure is described below with reference to fig. 2 and 3.
Fig. 2 shows a flow chart of an application example of the parameter configuration method disclosed in the present disclosure. As shown in fig. 2, first, the terminal reports a measurement report to the source cell base station, and the source cell base station transmits a conditional handover request to the candidate cell base station, receives a conditional handover response from the candidate cell base station, and transmits an RRC reconfiguration message to the terminal. And after triggering the update of the condition switching configuration parameters, the source cell base station sends the configuration update of the source cell base station to the candidate cell, receives the condition switching configuration update from the candidate cell base station, and sends an RRC reconfiguration message to the terminal again.
Fig. 3 shows a flow chart of another application example of the parameter configuration method disclosed in the present disclosure. As shown in fig. 3, first, the terminal reports a measurement report to the source cell base station, and the source cell base station transmits a conditional handover request to the candidate cell base station, receives a conditional handover response from the candidate cell base station, and transmits an RRC reconfiguration message to the terminal. And when the candidate cell base station triggers the condition switching configuration parameter to update, the candidate cell configuration update is sent to the source cell, and the source cell base station sends the RRC reconfiguration message to the terminal again.
In some embodiments, in step S102, the source cell base station may send a Radio Resource Control (RRC) reconfiguration message to the terminal, where the RRC reconfiguration message carries the updated conditional handover configuration parameter. Correspondingly, after receiving the RRC connection reconfiguration message in step S103, the terminal immediately parses the infinite configuration parameter of the source cell base station, the infinite configuration parameter of the candidate cell base station, and the conditional handover execution condition to check whether the updated conditional handover configuration parameter is supported. Specifically, two cases can be classified:
(case C) terminal support updated conditional handover configuration parameters
And under the condition that the terminal supports the updated conditional handover configuration parameters, the terminal configures the updated conditional handover configuration parameters to the bottom layer when the conditional handover execution conditions are met, and feeds back an RRC reconfiguration completion message to the base station of the source cell. And the source cell base station receives the RRC reconfiguration completion message sent by the terminal.
(case D) the terminal does not support the updated conditional handover configuration parameters
And under the condition that the terminal does not support the updated conditional switch configuration parameters, the terminal starts an RRC reestablishment process, sends an RRC connection reestablishment request to the source cell base station, and the source cell base station receives an RRC connection reestablishment message sent by the terminal.
The embodiment can detect whether the terminal supports the detection result sent after the updated conditional switch configuration parameter. When the terminal supports the updated conditional switch configuration parameters, the configuration is completed, and when the terminal does not support the updated conditional switch configuration parameters, the configuration is reported in time and RRC connection reestablishment is carried out, so that the robustness of cell switching is further improved.
