A service provisioning system, comprising: at least one mobile edge application server, MEAS, and at least one mobile edge application server support function, MEAS-SF, wherein the MEAS is deployed at an access network side and connected to one or more base stations; the MEAS-SF is deployed at a core network side, connected to one or more MEASs, and connected to a packet data network gateway, P-GW; the MEAS is configured to: receive, through a connected base station, a service request sent by a user equipment, wherein the service request indicates that the user equipment requests service data from a service provider, SP, and determine whether the MEAS can provide the user equipment with the service data requested in the service request; if the MEAS can provide the user equipment with the service data requested in the service request, send the service request to the MEAS-SF, send the service data requested in the service request to the user equipment through the connected base station, and synchronize, with the MEAS-SF, protocol stack information between the user equipment and the SP; if the MEAS cannot provide the user equipment with the service data requested in the service request, send the service request to the MEAS-SF, obtain, from the MEAS-SF, the service data requested in the service request and sent by the SP, and send, to the user equipment through the connected base station, the service data requested in the service request and sent by the SP; the MEAS-SF is configured to: receive the service request sent by the MEAS, send the service request to the SP through the P-GW, and receive, through the P-GW, the service data requested in the service request and sent by the SP, so that the core network side charges for the service request and the service data requested in the service request. receive, through a connected base station, a service request sent by a user equipment, wherein the service request indicates that the user equipment requests service data from a service provider, SP, and determine whether the MEAS can provide the user equipment with the service data requested in the service request; if the MEAS can provide the user equipment with the service data requested in the service request, send the service request to the MEAS-SF, send the service data requested in the service request to the user equipment through the connected base station, and synchronize, with the MEAS-SF, protocol stack information between the user equipment and the SP; if the MEAS cannot provide the user equipment with the service data requested in the service request, send the service request to the MEAS-SF, obtain, from the MEAS-SF, the service data requested in the service request and sent by the SP, and send, to the user equipment through the connected base station, the service data requested in the service request and sent by the SP; the MEAS-SF is configured to: receive the service request sent by the MEAS, send the service request to the SP through the P-GW, and receive, through the P-GW, the service data requested in the service request and sent by the SP, so that the core network side charges for the service request and the service data requested in the service request.
