Abstract
A method and a Mobile Access Gateway (MAG) node for use in an IP network. The MAG node comprises a server for providing configuration information. The server includes a memory for storing configuration information, and a processing unit configured to generate a request for configuration information associated with a mobile terminal that has attached to the network. The server caches the configuration information in the server memory, and includes one or more items of configuration information from the cached information in a message to be sent to the mobile terminal.
Claims29
A Mobile Access Gateway node of an IP network, the Mobile Access Gateway node comprising:
- a server configured to provide configuration information, said server including a server memory configured to store configuration information, and a processing unit configured to generate a request for configuration information associated with a mobile terminal that has attached to the network, to cache the configuration information in the server memory, and to include one or more items of configuration information from the cached information in a message to be sent to the mobile terminal;
- wherein the configuration information comprises Dynamic Host Configuration Protocol (DHCP) information and includes an IPv4 Home Address, and an IPv6 Home Network Prefix (HNP) for the mobile terminal;
- wherein the processor is configured to ignore a first DHCP Request sent from the mobile terminal using a unicast address for a server of another Mobile Access Gateway and to provide a DHCP server address to the mobile terminal in response to a DHCP Discovery message sent from the mobile terminal using a broadcast address for multiple DHCP servers.
A method of providing configuration information to a mobile terminal, the method comprising:
- receiving a request from the mobile terminal to attach to an IP network via a Mobile Access Gateway node;
- generating and sending a request from the Mobile Access Gateway node for provision of configuration information associated with the mobile terminal;
- obtaining the requested configuration information;
- caching the configuration information at the Mobile Access Gateway node;
- ignoring a first Dynamic Host Configuration Protocol (DHCP) Request sent from the mobile terminal using a unicast address for a server of another Mobile Access Gateway and received at the Mobile Access Gateway node;
- and
- providing a DHCP server address to the mobile terminal in response to a DHCP Discovery message sent from the mobile terminal using a broadcast address for multiple DHCP servers.
A method of providing configuration information to a mobile terminal, the method comprising:
- receiving a request from the mobile terminal to attach to an IP network via a Mobile Access Gateway node;
- generating and sending a request from the Mobile Access Gateway node for provision of configuration information associated with the mobile terminal wherein the request for the provision of configuration information is sent to a Local Mobility Anchor node associated with the mobile terminal;
- obtaining the requested configuration information;
- caching the configuration information at the Mobile Access Gateway node;
- intercepting at the Mobile Access Gateway node all Dynamic Host Configuration Protocol (DHCP) Request messages sent from the mobile terminal to a unicast address for a server of another Mobile Access Gateway,
- ignoring destination addresses of the DHCP Request messages received at the Mobile Access Gateway node that were sent to a unicast address for a server of another Mobile Access Gateway, and
- treating the messages that were sent to a unicast address for a server of another Mobile Access Gateway as DHCP Requests destined for a DHCP server in the Mobile Access Gateway node.
