Device and Method for Implementing Data Service

A data service charging system, comprising:

• a first network-side device and a second network-side device,
• wherein the first network-side device is configured to:
• determine a status of a data service switch of user equipment (UE) based on an uplink data packet from the UE, the status of the data service switch indicating whether the data service switch is turned on;
• and
• send a first notification message
• comprising first instruction information and an identity of the UE to a second network-side device in response to the data service switch of the UE being turned off, the first instruction information instructing the second network-side device to skip charging for data packets destined for the UE and flowing through the second network-side device, the data packets destined for the UE comprising at least one of downlink data packets or uplink data packets;
• and
• wherein the second network-side device is configured to:
• receive the first notification message from the first network-side device;
• and
• skip charging for the data packets destined for the UE according to the first notification message.
