1. A network device, comprising:
a transceiver, configured to receive an uplink data packet; and
a processor configured to determine whether a data format of the uplink data packet is a first data format or a second data format,
wherein the first data format indicates that the uplink data packet is at least one of encrypted with a first key of a source base station or compressed with a first ROHC profile of the source base station, and the second data format indicates that the uplink data packet is at least one of encrypted with a second key of a target base station or compressed with a second ROHC profile of the target base station,
wherein the processor is configured to: determine, through a RLC entity corresponding to the uplink data packet, whether the data format of the uplink data packet is the first data format or the second data format,
wherein the uplink data packet of the source base station is borne on a first RLC entity of the source base station, and the uplink data packet of the target base station is borne on a second RLC entity of the target base station;
wherein the processor is configured to determine that the data format of the uplink data packet is the first data format when the uplink data packet received by the transceiver is borne on the first RLC entity of the source base station, and
wherein the processor is configured to determine that the data format of the uplink data packet is the second data format when the uplink data packet received by the transceiver is borne on the second RLC entity of the target base station.
