AGGREGATION MANAGEMENT SYSTEM, AGGREGATE NODE, AND DEAGGREGATE NODE

摘要

A technology for providing an aggregation management system and the like which can quickly and efficiently manage aggregation in a mobile-environment is disclosed. According to the technology, an aggregate node adds mobile status information to signaling messages of end-to-end signaling sessions received from mobile terminals 101 to 105, and sends the signaling messages added with the mobile status information to a deaggregate node 117 in new aggregated sessions where the aggregate node is shifted. The deaggregate node in the new aggregated sessions where the aggregate node is shifted (or relay nodes 131 to 135 as a crossover node) which receives the signaling messages added with the mobile status information, based on the mobile status information, release aggregated sessions before the aggregate node is shifted, or sends a message to release the aggregated sessions to a deaggregate node 113 before the aggregate node is shifted.
