Abstract

Official abstract text for this publication.

When a mobile terminal transmitting/receiving a packet using a plurality of IP address types performs a handover to an access network (single address type connection network) permitting transmission/reception of a packet using a single IP address only, an IP address not permitted is unfortunately discarded at an access network as a handover destination. Disclosed is a technique configured so that a mobile terminal (UE 1 ) detecting a handover to the single address type connection network establishes a temporary connection with a mobility management gateway (PGW 5 ) and thereafter acquires an address of an ePDG 8 located at a core network and informs the ePDG of a communication state before the handover via a PDN using the temporary connection. The ePDG informs the PGW of the communication state of the UE before the handover. Thereby, the communication state of the UE before the handover is achieved with the PGW via the ePDG and the PDN.

First claim

Opening claim text (preview).

The invention claimed is: 1. A connection management method in a communication system comprising a mobile terminal capable of establishing a plurality of packet data connections using a plurality of Internet Protocol (IP) addresses; a packet data gateway establishing a packet data connection with the mobile terminal and a mobility management gateway managing connection information on a packet transmission/reception with the mobile terminal, the method being for managing connections…
