A cell measurement method performed by a user equipment, UE, the method comprising: receiving, from a source base station, measurement configuration information which may include core network type reporting information, where the core network type reporting information instructs the UE to measure n neighbour cells of the source base station and to report first core network type information of n respective neighbour cells for the UE in a measurement report sent to the source base station, where n is a positive integer and wherein the first core network type information indicates at least one of: a type of a core network accessed by a base station to which a respective neighbour cell belongs, or an identifier of a network slice supported by a base station to which a respective neighbour cell belong; performing, by the UE, cell measurement according to the measurement configuration information; when a cell measurement result satisfies a reporting condition, sending a measurement report to the source base station; wherein the sending comprises: if the measurement configuration information includes the core network type reporting information, the measurement report includes said first core network type information of the n respective neighbour cells in accordance to the indication; and if the measurement configuration information does not include the core network type reporting information, the UE determines whether data other than the first core network type information in the measurement report fully occupy uplink resources allocated to the UE by the source base station, wherein: if data other than the first core network type information in the measurement report fully occupy uplink resources allocated to the UE by the source base station, the measurement report does not include the first core network type information, and if data other than the first core network type information in the measurement report do not fully occupy uplink resources allocated to the UE by the source base station, the measurement report includes the first core network type information. receiving, from a source base station, measurement configuration information which may include core network type reporting information, where the core network type reporting information instructs the UE to measure n neighbour cells of the source base station and to report first core network type information of n respective neighbour cells for the UE in a measurement report sent to the source base station, where n is a positive integer and wherein the first core network type information indicates at least one of: a type of a core network accessed by a base station to which a respective neighbour cell belongs, or an identifier of a network slice supported by a base station to which a respective neighbour cell belong; performing, by the UE, cell measurement according to the measurement configuration information; when a cell measurement result satisfies a reporting condition, sending a measurement report to the source base station; wherein the sending comprises: if the measurement configuration information includes the core network type reporting information, the measurement report includes said first core network type information of the n respective neighbour cells in accordance to the indication; and if the measurement configuration information does not include the core network type reporting information, the UE determines whether data other than the first core network type information in the measurement report fully occupy uplink resources allocated to the UE by the source base station, wherein: if data other than the first core network type information in the measurement report fully occupy uplink resources allocated to the UE by the source base station, the measurement report does not include the first core network type information, and if data other than the first core network type information in the measurement report do not fully occupy uplink resources allocated to the UE by the source base station, the measurement report includes the first core network type information.
