Abstract
A node on a core network, in accordance with a connection state of a terminal, releases a transmission path resource which is made unnecessary due to LIPA (Local IP access) or SIPTO (Selected IP traffic offload) connection configuration.
Claims6
A method for a mobile communication system, the method comprising:
- releasing, by an MME (Mobility Management Entity), bearers in an SGW (Serving Gateway) by sending a request to the SGW when SIPTO (Selected IP Traffic Offload) is established;
- and
- sending, by the SGW, a response to the MME.
A mobile communication system, the system comprising:
- an MME (Mobility Management Entity);
- and
- an SGW (Serving Gateway),
- wherein the MME releases bearers in the SGW by sending a request to the SGW when SIPTO (Selected IP Traffic Offload) is established, and
- wherein the SGW sends a response to the MME.
