Abstract

A user equipment (UE) and an operating method of the UE in a communication system are provided. The method includes registering the UE through a first cell using a first access technology; detecting a second cell using a second access technology; receiving a first data through the first cell using the first access technology; and receiving a second data through a second cell using the second access technology, wherein the first cell and the second cell are simultaneously active for the UE, and at least one of the first data and the second data is selectively received through at least one of the first cell and the second cell.

Claims

1. An operating method of a user equipment (UE) in a communication system, comprising:

attaching the UE to a first cell using a first access technology;

detecting a second cell using a second access technology different from the first access technology; and

receiving data through the first cell or the second cell,

wherein the first cell and the second cell are simultaneously active for the UE,

wherein first data received through the first cell and second data received through the second cell are split at one core network and transmitted on two separate sessions, and

wherein a first session of the two separate sessions is transmitted via the first cell and a second session of the two separate sessions is transmitted via the second cell.

2. The method of claim 1, further comprising:

transmitting capability information on data reception through the second cell using the second access technology, to the first cell.

3. The method of claim 1, further comprising:

receiving configuration information for the second cell using the second access technology, on the first cell.

4. The method of claim 1, wherein uplink (UL) data is transferred through the first cell using the first access technology, while the first cell and the second cell are simultaneously active for the UE.

5. A user equipment (UE) in a communication system, comprising:

a memory; and

at least one processor coupled to the memory,

wherein the at least one processor is configured to;

attach the UE to a first cell using a first access technology,

detect a second cell using a second access technology different from the first access technology, and

receive data through the first cell or the second cell, and

wherein the first cell and the second cell are simultaneously active for the UE,

wherein first data received through the first cell and second data received through the second cell are split at one core network and transmitted on two separate sessions, and

wherein a first session of the two separate sessions is transmitted via the first cell and a second session of the two separate sessions is transmitted via the second cell.

6. The UE of claim 5, wherein the processor is further configured to transmit capability information on data reception through the second cell using the second access technology, to the first cell.

7. The UE of claim 5, wherein the processor is further configured to receive configuration information for the second cell using the second access technology, on the first cell.

8. The UE of claim 5, wherein uplink (UL) data is transferred through the first cell using the first access technology, while the first cell and the second cell are simultaneously active for the UE.
