Cooperative communication method, cloud server, and core network server

A cooperative communication method, comprising:

• receiving a request message sent by a cloud server, wherein the request message is used to request bandwidth support, and wherein the request message comprises an identifier of user equipment (UE) and location information of a cell in which the UE is located;
• determining, according to the location information of the cell in which the UE is located, a wireless network on which the UE is located;
• establishing a connection to a base station on the wireless network;
• acquiring, from the base station, wireless bandwidth that the wireless network can provide for the UE;
• and
• sending a feedback message to the cloud server, wherein the feedback message carries the wireless bandwidth.

A cloud server, wherein the cloud server is connected to multiple core networks, and wherein the cloud server comprises:

• a processor configured to:
• determine bandwidth of a first wireless network that user equipment (UE) currently accesses;
• and
• determine bandwidth required by data to be sent to the UE;
• and
• a transmitter coupled to the processor and configured to:
• send a first part of data packets to the first wireless network when the bandwidth of the first wireless network determined by the processor cannot meet the bandwidth required by the data to be sent to the UE;
• and
• send a second part of the data packets to at least one core network, so that the at least one core network sends the second part of the data packets to the UE using at least one wireless network, wherein the first part of the data packets and the second part of the data packets belong to the data to be sent to the UE, and wherein a communications protocol of the first wireless network is different from that of the at least one wireless network.

A core network server, comprising:

• a receiver configured to receive a request message sent by a cloud server, wherein the request message is used to request bandwidth support, and wherein the request message comprises an identifier of user equipment (UE) and location information of a cell in which the UE is located;
• a processor coupled to the receiver and configured to:
• determine, according to the location information of the cell in which the UE is located, a wireless network on which the UE is located;
• establish a connection to a base station on the wireless network;
• and
• acquire, from the base station, wireless bandwidth that the wireless network can provide for the UE;
• and
• a transmitter coupled to the processor and configured to send a feedback message to the cloud server, wherein the feedback message carries the wireless bandwidth.
