In a heterogeneous network, a terminal may perform a base station handover in some cases, for example, a handover from a macro base station to a small base station, a handover from a small base station to another small base station, or the like.
However, in the prior art, when a terminal performs a base station handover, a source base station (i.e. a base station currently providing services for the terminal) does not know which cell under a target base station supports a voice service, so that the source base station only obtains the target cell under the target base station as a cell for the terminal handover by using a measurement report sent by the terminal and mobility restriction of the target base station when performing a handover decision.

The configuration update information refers to information that some configuration of the target base station is changed. The configuration update information includes a VOICE capability attribute update parameter of the serving cell, for example, the original VOICE capability attribute information of the serving cell is an attribute with VOICE capability, and when the serving cell changes to an attribute without VOICE capability, the VOICE capability attribute update parameter may be VOICE NOT SUPPORTED.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not intended to limit the present embodiment.
When some configuration of the target base station is changed, configuration update information may be generated and sent to the source base station, and of course, in this embodiment, the configuration update information includes a voice capability attribute update parameter corresponding to the serving cell, that is, the voice capability attribute of the serving cell is changed. As shown in fig. 2b, when the voice capability attribute information of the cell under the source base station (i.e. NG-RAN NODE 1) is changed, the changed voice capability UPDATE parameter may be sent to the target base station (i.e. NG-RAN NODE 2) through the NG-RAN NODE CONFIGURATION UPDATE information, and the target base station may UPDATE the stored voice capability attribute information of the cell under the source base station according to the voice capability UPDATE parameter.

For example, when the voice capability attribute of the originally stored serving cell is an attribute with voice capability and the voice capability attribute update parameter included in the received configuration update information is information that does not support voice capability, the stored voice capability attribute information of the serving cell may be updated to an attribute without voice capability.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present application, and are not intended to limit the present embodiment.

substep M1: and under the condition that the terminal is determined not to carry out the voice service currently according to the service state information, determining at least one cell to be confirmed in the service cells according to the access constraint conditions of the service cells.
In the embodiment of the present application, a cell to be confirmed refers to a cell screened from a serving cell and allowing a terminal to access.

And when the cell with the voice capability exists in at least one cell to be confirmed, screening a target cell from the cells with the voice capability according to the cell load state of the cells with the voice capability. For example, when the cell with voice capability includes cell 1, cell 2 and cell 3, the load of cell 1 is greater than the load of cell 2, and the load of cell 2 is greater than the load of cell 3, then cell 3 is selected as the target cell, that is, the cell with the smallest load is selected as the target cell.

For example, the serving cell may include cell 1, cell 2, cell 3, and cell 4, where the cells that the terminal is allowed to access are cell 2, cell 3, and cell 4, and then cell 2, cell 3, and cell 4 are to-be-confirmed cells.

When there is no cell with voice capability in the at least one initial serving cell, a cell to be handed over may be screened from the at least one initial serving cell according to a cell load status of the at least one initial serving cell, for example, the initial serving cell includes a cell a, a cell b, and a cell c, where a load of the cell a is greater than a load of the cell b, and a load of the cell b is greater than a load of the cell c, and then the cell c is selected as the cell to be handed over.
After the cell to be switched is determined, a switching operation of switching from the access cell of the source base station to the cell to be switched can be executed for the terminal, that is, the terminal is switched to the cell to be switched, so that the cell to be switched provides service for the terminal.
In this embodiment, when the terminal does not currently perform the voice service, the cell with the voice capability is preferentially selected as the cell to which the terminal is switched, so that the time delay caused by the terminal in the subsequent voice service can be avoided. When the service cell has no voice capability, the cell with lower load can be selected as the cell for terminal switching, so that the utilization rate of the cell can be improved.
