Inventor: ITO YOSHIHISA
IPC: H04W92/14
Filed: 2019-09-30
Abstract: To provide a communication system capable of improving communication efficiency between terminals subordinate to an identical base station while suppressing impediment of communication other than between the terminals subordinate to the identical base station.SOLUTION: In a communication system conforming to LTE communication system, a base station device keeps, as attribute information for establishing a bearer between a core network device and each terminal, first information for identifying a network outside of the core network device of the bearer and second information indicating an IP address of the terminal of the bearer. The base station device determines whether an IP packet received from the first terminal coincides with information identifying the network outside of the core network device of the bearer and the first information kept by the base station device, and whether the IP address contained in the IP packet coincides with the second information kept by the base station device. When the first information and the second information coincide, the base station device transmits the IP packet from a first terminal to a second terminal by using a bearer specified by the first and second information.SELECTED DRAWING: Figure 3
