Patent ID: 8125939

Claim:
A base station apparatus coupled to a base station controller, comprising: a processor to execute processes including: establishing a first logic communication path between the base station apparatus and the base station controller; establishing a second logic communication path between the base station apparatus and another base station apparatus; forwarding, by a forwarding circuit, data, transmitted and received with the another base station apparatus and the base station controller serving as terminal points, as data of the another base station via the first logic communication path and the second logic communication path; setting, within the first logic communication path, a communication pipe via which to transmit the data transmitted and received with the base station apparatus and the base station controller serving as the terminal points and a communication pipe via which to transmit the data of the another base station apparatus; setting, within the second logic communication path, a communication pipe via which to transmit the data transmitted and received as inter-base-station data with the base station apparatus and the another base station apparatus serving as the terminal points and a communication pipe via which to transmit the data of the another base station apparatus; storing a combination of identifying information specifying the communication pipe via which to transmit the data of the another base station apparatus that is set within the first logic communication path and identifying information specifying the communication pipe via which to transmit the data of the another base station apparatus that is set within the second logic communication path in a forwarding table; and forwarding the data of the another base station apparatus in the received pieces of data on the basis of the communication pipe identifying information set in the received pieces of data and the forwarding table.
