A method and device for hosting an application by an access node which provides network access to a terminal in a mobile communication system are provided. The method includes receiving a request packet for a service request from a user application of a mobile terminal, delivering the request packet to an application included in the access node, if a destination of the request packet corresponds to the application of the access node, providing a service to the user application of the mobile terminal through the application, and delivering the request packet to a corresponding public application on an external network, if the application corresponding to the destination of the request packet does not exist in the access node.

Method and device for hosting application by access node

To forward traffic to a base station using Software Defined Network technology, a method for operating a switch includes receiving path information of a packet to be forwarded from a source terminal to a plurality of destination terminals, from a controller, receiving the packet to be forwarded from the source terminal to the destination terminals, from a base station, and transmitting the packet along a path determined by the path information. An apparatus for controlling a switch in a communication network includes a transceiver configured to receive information of a source terminal and a plurality of destination terminals, from a server which controls a service for forwarding traffic from the source terminal to the destination terminals, and a controller configured to determine a packet forward path between the source terminal and the destination terminals, wherein the transceiver transmits the determined path information to at least one switch.

Apparatus and method for forwarding data based on software defined network in communication network

A method for operating a switch in a communication network includes receiving path information of a service flow between a first user equipment (UE) and a second UE from a controller, receiving a packet forwarded through the service flow from a base station, and transmitting the packet to a path determined by the path information. An apparatus for a switch in a communication network includes a controller configured to receive path information of a service flow between a first user equipment (UE) and a second UE from a controller, receive a packet forwarded through the flow from an evolved NodeB and forward the packet to a path determined by the path information. Other embodiments are also disclosed.

Method and apparatus for enhancing voice service performance in communication system

A method and device for processing a service in a mobile communication system based on SDN technology are provided. The method of controlling access caches in a communication network includes receiving information about contents requested by a user equipment (UE) connected to a first base station. The method also includes transmitting a forwarding request that requests to control at least one switch in order for an access cache that has the contents and that interworks with a second eNB to transfer the contents to the first eNB.

Method and device for processing service in software-defined networking system

An apparatus and method for enabling duplication between line cards of between physical links when Internet Protocol (IP) packet data of a backbone network is transmitted through a physical link (T1/E1/J1) in an IP-BSS system is provided. The apparatus includes a scheduler for examining a queue depth of queues stored in a queue buffer of each of a plurality of line cards. The apparatus also includes a virtual queue manager for receiving the queue depth from the scheduler, for fragmenting the IP packet received through a backbone network, for determining priority of the line cards according to the queue depth, and also for transmitting the fragmented packet according to the priority.

Apparatus and method for link duplication in mobile communication system

An apparatus and method for managing a packet transmission delay for TCP/IP-based communications in a mobile communication system are provided, in which a BSC imposes no delay on a packet directed to an MS or a packet transmitted from the MS and sends the packet to the MS or corresponding MS, if it is determined that the MS starts to perform a handover during communications with the MS, and delays a packet directed to the MS or a packet transmitted from the MS and sends the delayed packet to the MS or corresponding MS, if it is determined that the MS has completed the handover during the packet transmission with no delay. Advantageously, timeout occurrences caused by too long a time delay are reduced, thereby preventing decreased throughput during the TCP/IP-based handover.
