In a home agent for designating a transmission period of a binding update packet transmitted from a mobile node, a central processing monitor detects a usage rate of a CPU for processing accompanied by a reception of a binding update packet from the mobile node or a binding renewal message among the binding update packets, a line usage rate monitor detects a line usage rate of a receiving interface accompanied by the processing or a transmitting interface, a BC number monitor detects a binding cache number, and a calculator calculates a transmission period of the binding renewal message of the mobile node based on the thus detected CPU usage rate, line usage rate, binding cache number, and a priority table of the mobile node.
