2. The method as claimed in claim 1 , wherein the message including the information uses a Radio Resource Control (RRC) connection release message.
3. The method as claimed in claim 1 , wherein the indication information indicating is provided via the eNode B from the server.
4. The method as claimed in claim 1 , wherein the server acquires the indication information from a Domain Name Server (DNS), the local gateway via a serving gateway, or the eNode B, if the server receives a PDN connectivity request from the UE.
5. A User Equipment (UE) for supporting local access and voice communication in a wireless network, the UE comprising:
a transceiver configured to transmit and receive messages over the wireless network; and
a controller configured to:
transmit a message for requesting a Circuit Switch (CS)-based voice service to a eNode B, the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection, and
receive, from the eNode B, a message including information indicating that the local IP-based PDN connection is suspended and is not deactivated, if it is determined by a server managing mobility of the UE that suspending the local IP-based PDN connection is supported in a local gateway.
6. The UE as claimed in claim 5 , wherein the message including the information uses a Radio Resource Control (RRC) connection release message.
7. The UE as claimed in claim 5 , wherein the indication information is provided via the eNode B from the server.
8. The UE as claimed in claim 5 , wherein the server acquires the indication information from a Domain Name Server (DNS), the local gateway via a serving gateway, or the eNode B, if the server receives a PDN connectivity request from the UE.
9. A method for supporting local access and voice communication by an eNode B in a wireless network, the method comprising:
receiving a message for requesting a Circuit Switch (CS)-based voice service from a User Equipment (UE), the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection; and
transmitting, to the UE, a message including information indicating that the local IP-based PDN connection is suspended and is not deactivated, if it is determined by a server managing mobility of the UE that suspending the local IP-based PDN connection is supported in a local gateway.
10. The method as claimed in claim 9 , wherein the message including the information uses a Radio Resource Control (RRC) connection release message.
11. The method as claimed in claim 9 , wherein the indication information is provided from the server.
12. The method as claimed in claim 9 , wherein the server acquires the indication information from a Domain Name Server (DNS), the local gateway via a serving gateway, or the eNode B, if the server receives a PDN connectivity request from the UE.
13. The method as claimed in claim 9 , further comprising not releasing a bearing for the local IP-based PDN connection, if suspending the local IP-based PDN connection is supported in the local gateway.
14. An eNode for supporting local access and voice communication in a wireless network, the eNode comprising:
a transceiver configured to transmit and receive messages over the wireless network;
a controller configured to:
receive a message for requesting a Circuit Switch (CS)-based voice service from a User Equipment (UE), the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection, and
transmit, to the UE, a message including information indicating that the local IP-based PDN connection is suspended and is not deactivated, if it is determined by a server managing mobility of the UE determines that suspending the local IP-based PDN connection is supported in a local gateway.
15. The eNode as claimed in claim 14 , wherein the message including the information uses a Radio Resource Control (RRC) connection release message.
16. The eNode as claimed in claim 14 , wherein the indication information is provided from the server.
17. The eNode as claimed in claim 14 , wherein the server is configured to acquire the indication information from a Domain Name Server (DNS), the local gateway via a serving gateway, or the eNode B, if the server receives a PDN connectivity request from the UE.
18. The eNode as claimed in claim 14 , wherein the controller is further configured not to release a bearer for the local IP-based PDN connection, if suspending the local IP-based PDN connection is supported in the local gateway.
19. A method for supporting local access and voice communication by a server managing mobility in a wireless network, the method comprising:
receiving a message for requesting a Circuit Switch (CS)-based voice service from a User Equipment (UE) via an eNode B, the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection; and
transmitting, to the UE via the eNode B, information indicating that the local IP-based PDN connection is suspended and is not deactivated, if the server managing mobility of the UE determines that suspending the local IP-based PDN connection is supported in a local gateway.
20. The method as claimed in claim 19 , wherein the indication information is provided to the eNode B together with a message allowing the CS-based voice service to the UE.
21. The method as claimed in claim 19 , wherein the server acquires the indication information from a Domain Name Server (DNS), the local gateway via a serving gateway, or the eNode B, if the server receives a PDN connectivity request from the UE.
22. The method as claimed in claim 19 , further comprising suspending a bearer for the local IP-based PDN connection by transmitting the indication information to the local gateway via a serving gateway.
23. A server for supporting local access and voice communication in a wireless network, the server comprising:
a communication interface configured to communicate with network entities; and
a controller configured to:
receive a message for requesting a Circuit Switch (CS)-based voice service from a User Equipment (UE) via an eNode B, the UE having a local Internet Protocol (IP)-based Packet Data Network (PDN) connection, and
transmit, to the UE via the eNode B, information indicating that the local IP-based PDN connection is suspended and is not deactivated, if the server managing mobility of the UE determines that suspending the local IP-based PDN connection is supported in a local gateway.
