Communication method for dual-card user equipment and apparatus

A network side device, comprising:

• a first receiver, configured to receive an access request from a dual-card user equipment (UE);
• a first processor, configured to:
• acquire association information between a first card of the dual-card UE and a second card of the dual-card UE,
• establish a first bearer according to the access request,
• establish a second bearer according to the association information, and
• split first data to be transmitted into second data and third data, wherein the association information comprises an identifier of the second card of the dual-card UE, or an identifier of the second card of the dual-card UE and an address of a core network entity with which the second card of the dual-card UE is registered, the first bearer is a data transmission channel between the network side device and the first card of the dual-card UE, the second bearer is a data transmission channel between the network side device and the second card of the dual-card UE, and the network side device provides a service for the first card of the dual-card UE;
• and
• a first sender, configured to send the second data to the dual-card UE by using the first bearer, and send the third data to the dual-card UE by using the second bearer, so that the dual-card UE combines the second data and the third data into the first data.

A communication method for a dual-card user equipment (UE), the method comprising:

• receiving, by a first network side device, an access request from the dual-card UE, and establishing a first bearer according to the access request, wherein the first network side device provides a service for a first card of the dual-card UE, and the first bearer is a data transmission channel between the first network side device and the first card of the dual-card UE;
• acquiring, by the first network side device, association information between the first card of the dual-card UE and a second card of the dual-card UE;
• wherein the association information comprises an identifier of the second card of the dual-card UE, or an identifier of the second card of the dual-card UE and an address of a core network entity with which the second card of the dual-card UE is registered;
• establishing, by the first network side device, a second bearer according to the association information, wherein the second bearer is a data transmission channel between the first network side device and the second card of the dual-card UE;
• receiving, by the first network side device, second data and third data from the dual-card UE, wherein the second data is sent by the dual-card UE by using the first bearer after the dual-card UE splits first data to be transmitted into the second data and the third data, and the third data is sent by the dual-card UE by using the second bearer;
• and
• combining, by the first network side device, the second data and the third data into the first data.
