Abstract
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.
Claims20
A method for operating a switch connected to a controller in a software-defined network (SDN) based mobile communication network, the method comprising:
- performing, through a mobility management entity (MME), bearer setup with a user equipment (UE) accessed to a based station (BS), the BS connected to a first access cache not storing contents;
- transmitting, to the controller, information for the bearer setup and an UE internet protocol (IP) address allocated by the MME;
- receiving, from the UE, a packet for requesting contents;
- transmitting, to a deep packet inspection (DPI) connected to the controller, header information that is generated based on the packet;
- receiving, from the controller, a message for setting a path between the UE and a second access cache connected to a neighboring BS, the second access cache storing the contents;
- and
- providing, to the UE, the contents transmitted from the second access cache.
A method for operating a controller in a software-defined network (SDN) based mobile communication network, the method comprising:
- receiving, from a switch, information for bearer setup between the switch and an user equipment (UE) and an UE internet protocol (IP) address allocated by a mobility management entity (MME), wherein the UE is accessed to the BS and the BS is connected to a first access cache not storing contents;
- receiving, from a smart cache manager, a first message for notifying that a second access cache connected to a neighboring BS stores contents, wherein the contents is requested from the UE;
- and
- transmitting, to the switch, a second message for setting a path between the UE and the second access cache,
- wherein the first message is generated, by the controller, based on the information for the bearer setup and the UE IP address, and
- wherein the contents is provided to the UE from the second access cache.
An apparatus of a switch connected to a controller in a software-defined network (SDN) based mobile communication network, the apparatus comprising:
- a sub-controller configured to:
- perform, through a mobility management entity (MME), bearer setup with a user equipment (UE) accessed to a base station (BS), the BS connected to a first access cache not storing contents;
- transmit, to the controller, information for the bearer setup and an UE internet protocol (IP) address allocated by the MME;
- receive, from the UE, a packet for requesting contents;
- transmit, to a deep packet inspection (DPI) connected to the controller, header information that is generated based on the packet;
- receive, from the controller, a message for setting a path between the UE and a second access cache connected to a neighboring BS, the second access cache storing the contents;
- and
- provide, to the UE, the contents transmitted from the second access cache.
An apparatus of a controller in a software-defined network (SDN) based a mobile communication network, the apparatus comprising:
- a sub-controller;
- and
- a communication interface operatively coupled to the sub-controller,
- wherein the sub-controller is configured to:
- receive, from a switch, information for bearer setup between the switch and an user equipment (UE) and an UE internet protocol (IP) address allocated by a mobility management entity (MME), wherein the UE is accessed to the BS and the BS is connected to a first access cache not storing contents;
- receive, from a smart cache manager, a first message for notifying that a second access cache connected to a neighboring BS stores contents, wherein the contents is required from the UE;
- and
- transmit, to the switch, a second message for setting a path between the UE and the second access cache, wherein the first message is generated, by the controller, based on the information for the bearer setup and the UE IP address, and wherein the contents is provided to the UE from the second access cache.
