Abstract
Disclosed is a technique for allowing a mobility service provider to allocate a home agent appropriate for each individual mobile node. According to the technique, an MN 10 notifies the domain name of an MSP 3 to an ASP 1, and in response to the notified domain name of the MSP, the ASP notifies the address of an HA allocation server 3a to the MN. The MN transmits, to the notified address of the HA allocation server, an HA allocation request message including the domain name of the ASP. The HA allocation server selects an HA based on previously held correspondences between HAs 3b, 3c and one or more ASPs, and notifies the selected HA to the MN.

1-2. (canceled)
A communication system having one or more home agents provided in a first provider providing a mobility service and a home agent allocation server provided in the first provider or a second provider providing an access service, and causing a mobile node to acquire a home address from a home agent, the communication system comprising:
- a section that causes the home agent allocation server to hold, in advance, correspondences between the one or more home agents and one or more second providers;
- a section that causes the mobile node to transmit, to an address of the home agent allocation server, a home agent allocation request message including identification information of a second provider;
- and
- a section that causes the home agent allocation server to select a home agent based on the previously held correspondences between the home agents and the one or more second providers in response to the home agent allocation request message including the identification information of the second provider and notify the selected home agent to the mobile node,
- wherein the mobile node acquires a home address from the notified home agent.

A mobile node in a communication system having one or more home agents provided in a first provider providing a mobility service and a home agent allocation server provided in the first provider or a second provider providing an access service, and causing the mobile node to acquire a home address from a home agent, in which the home agent allocation server holds, in advance, correspondences between the one or more home agents and one or more second providers, the mobile node comprising:
- a transmission section that transmits, to an address of the home agent allocation server, a home agent allocation request message including identification information of a second provider;
- and
- an acquisition section that acquires a home address from a notified home agent when the home agent allocation server selects the home agent based on the previously held correspondences between the home agents and the one or more second providers in response to the home agent allocation request message including the identification information of the second provider and notifies the selected home agent to the mobile node.
