Abstract
The present invention introduces a method for managing the route to be used for the user's local device access traffic through the use of intelligent switching performed by the breakout node (eNodeB, home NodeB, or home eNodeB) together with the local access gateway node of the local service domain. Essential information pertaining to performance of this intelligent switching is obtained through the communication of specific tokens using selected channels of communication. A variety of combinations pertaining to the setup, selection and composition of token and channel is possible and described.
Claims7
Apparatus for use in a home base station that functions as a proxy for a user equipment (UE) accessing to a local IP network, the apparatus comprising:
- a token generating unit that generates a token to identify a communication channel between a packet data network gateway (PGW) and the home base station when establishing the communication channel, and sends the token to the PGW;
- a receiving unit that receives a token sent from the PGW via a mobility management entity (MME);
- a verifying unit that verifies whether the token received from the PGW is identical to the token created by the token generating unit;
- a proxy function that establishes a path between the home base station and the local IP network, and transfers packets received from the UE to the local IP network using the path;
- and
- an activating unit that activates the proxy function when the token received from the PGW is identical to the token created by the token generating unit.
A path optimization method for a home base station that functions as a proxy for a user equipment (UE) accessing to a local IP network, the method comprising:
- a token generating step that generates a token to identify a communication channel between a packet data network gateway (PGW) and the home base station when establishing the communication channel, and sends the token to the PGW;
- a receiving step that receives a token sent from the PGW via a mobility management entity (MME);
- a verifying step that verifies whether the token received from the PGW is identical to the token created by the token generating step;
- an activating step that activates a proxy function when the token received from the PGW is identical to the token created by the token generating step;
- and
- a transferring step executed by the activated proxy function that establishes a path, between the home base station and the local IP network, and transfers packets received from the UE to the local IP network using the path.
