Method and system of managing voice call and IP media sessions in a wireless network environment

A network entity of a first cell in a communication system, the network entity comprising:

• a memory;
• and
• at least one processor coupled to the memory,
• wherein the at least one processor is configured to:
• establish a first connection with a user equipment (UE) using a first access technology,
• receive, from the UE, via the first connection, capability information on communication with a second cell using a second access technology, wherein the second access technology is different from the first access technology,
• transmit, to the UE, via the first connection, a first signal, and
• transmit, to the UE, via the first connection, configuration information related to the second cell,
• wherein the first signal is transmitted to the UE via the first connection while the UE receives a second signal, from the second cell, via a second connection, between the UE and the second cell, and
• wherein the second connection is established between the UE and the second cell using the second access technology based on the configuration information.

A method of a user equipment (UE) in a communication system,

• the method comprising:
• establishing a first connection with a first cell using a first access technology;
• transmitting, to the first cell, via the first connection, capability information on communication with a second cell using a second access technology, wherein the second access technology is different from the first access technology;
• receiving a first signal from the first cell via the first connection;
• receiving configuration information related to the second cell from the first cell via the first connection;
• establishing a second connection with the second cell using the second access technology based on the configuration information;
• and
• receiving a second signal, from the second cell, via the second connection, while the first signal is received from the first cell.

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

• a memory;
• and
• at least one processor coupled to the memory,
• wherein the at least one processor is configured to:
• establish a first connection with a first cell using a first access technology,
• transmit, to the first cell, via the first connection, capability information on communication with a second cell using a second access technology, wherein the second access technology is different from the first access technology,
• receive a first signal from the first cell via the first connection,
• receive configuration information related to the second cell from the first cell via the first connection,
• establish a second connection with the second cell using the second access technology based on the configuration information, and
• receive a second signal, from the second cell, via the second connection, while the first signal is received from the first cell.
