1. A network system comprising:
- a switch unit arranged between a first network and a second network; and
an offloading determination unit that determines whether or not to perform offloading of a traffic for the first network, and that, when it is determined to perform offloading, configures an offload path that bypasses the first network, for the switch,a packet to be offloaded being forwarded between the offload path and the second network through the switch, when the traffic for the first network is offloaded.

Abstract
A switch is provided between a first network and a second network and an offloading determination unit determines whether or not to offload traffic for the first network, and configures an offload path to bypass the first network for the switch when the offloading is performed. When the traffic is offloaded, the switch forwards a packet to be offloaded to the offload path.

15. A network system, comprising:
-
an offloading unit that offloads a traffic for a first network; and an offloading determination unit that instructs the offloading unit to offload the traffic for the first network, wherein upon reception of an instruction of the offloading, the offloading unit determines whether or not to offload a received packet, and forwards the packet to an offload path that bypasses the first network. - View Dependent Claims (16, 17, 18, 19, 20)

21. A base station apparatus comprising:
-
a unit that, when offloading a traffic for a core network, transmits a request for configuring an offload path that bypasses the core network to a node including an offloading determination unit to determine whether or not to perform offloading of a packet received from a mobile terminal, and a unit that forwards the received packet to the offload path when the offloading is performed.

22. A base station apparatus;
- comprising;
a unit that receives an offload instruction from an offloading determination unit that instructs offloading of a traffic for a core network; a unit that determines whether or not to perform offloading of a packet received from a mobile terminal; and a unit that forwards the packet to be offloaded to an offload path that bypasses the core network, when the offloading is performed.
- comprising;
-
23. A control apparatus comprising:
-
a unit that receives a request for configuring an offload path from an offloading unit that performs offloading of a traffic for a first network; a unit that configures the offload path that bypasses the first network and connects to a second network, for a switch connected between the first network and the second network.

-
24. A control apparatus comprising:
-
a unit that transmits an offload instruction to an offloading unit that performs offloading of a traffic for a first network, upon reception of a request for configuring an offload path from the offloading unit; and a unit that causes the offloading unit to offload a received packet to be offloaded to the offload path configured to bypass the first network.

-
25. A network control method comprising:
-
determining whether or not to offload traffic for a first network and, when the offloading is performed; configuring an offload path to bypass the first network for switch arranged between the first network and a second network; and forwarding a packet to be offloaded between the offload path and the second network through the switch, when the traffic for the first network is offloaded. - View Dependent Claims (26)

27. A network control method comprising:
-
upon reception of an offload instruction by an offloading unit from an offloading determination unit that determines whether or not to perform offloading of a traffic for a first network; determining whether or not to perform offloading of a received packet; and when the offloading of the received packet is performed, forwarding the received packet to an offload path to bypass the first network. - View Dependent Claims (28)

29. A non-transitory computer readable recording medium storing therein a program for causing a computer comprising a base station apparatus to execute processing comprising:
-
when a packet that arrives from a mobile terminal via a radio bear is to be offloaded, transmitting, to a switch arranged between a first network and a second network, a connect request of an offload path configured to bypass the first network, directly or through the first network; and transmitting to the switch a disconnect request of the offload path, when a predetermined command is received from a node configured to manage mobility of the mobile terminal.

30. A non-transitory computer readable recording medium storing therein a program for causing a computer comprising a control apparatus configured to control a switch arranged between a first network and a second network to execute processing comprising:
-
upon reception, from a base station apparatus through the switch, a connect request of an offload path configured to bypass the first network, configuring the switch such that a packet forwarded from the base station apparatus to the offload path is forwarded to the second network and that a packet from the second network is forwarded to the offload path, and returning to the base station apparatus a connect response for the connect request of the offload path; and upon reception from the base station apparatus through the switch a disconnect request of the offload path, configuring the switch such that a gateway node of the first network is connected to the second network, and returning to the base station apparatus a disconnect response for the disconnect request of the offload path.
