Abstract
A method of selecting the serving network element in a telecommunications network. Mobility agents or routers transmit attribute information on one or more network elements in advertising messages to at least one mobile node. This information is used in the mobile node for selecting the serving network element.
Claims22
A method of using mobility agents in a telecommunications system, which telecommunications system comprises at least one mobile node supporting mobile IP and several network elements, of which network elements at least one comprises one or more mobility agents configured to transmit advertising messages to mobile nodes, the method comprising:
- establishing a data transmission connection between a mobility agent and one or more network elements in the system to collect attribute information,
- transmitting to the mobility agent information on attributes of one or more network elements from the connected one or more network elements,
- transmitting said information on the attributes in advertising messages from the mobility agent to at least one mobile node, and
- using said information in the mobile node in the selection of a serving network element.
A method of utilizing advertising messages in a telecommunications system, which telecommunications system comprises at least one mobile node and at least one router, the router being configured to transmit advertising messages to mobile nodes, the method comprising;
- establishing a connection between at least one router and at least one network element to collect attribute information,
- transmitting to the router information on attributes of one or more network elements from the connected network element,
- transmitting advertising messages from the router to at least one mobile node, the messages including said information on the attributes of one or more network elements, and
- using said information in the mobile node in selection of a serving network element.
A network element of a telecommunications system, the network element comprising:
- an IP mobility agent, wherein the network element is configured to connect an other network element to collect attribute information,
- the IP mobility agent is configured to receive information on attributes of one or more network elements from the other network element separate from the network element comprising the IP mobility agent, and
- the IP mobility agent is configured to transmit the information on attributes of one or more other network elements in advertising messages to at least one mobile node.
A mobile node supporting the mobile IP for a telecommunications system, which telecommunications system comprises several network elements, of which at least one comprises one or more mobility agents, said mobile node comprising:
- reception means for receiving in advertising messages attribute information on one or more network elements from at least one mobility agent, said information being received by the one or more mobility agents from another network element separate from the network element comprising the one or more mobility agents and connected to collect the attribute information received in advertising messages, and
- processing means for selecting a serving network element on the basis of said attribute information received in advertising messages.
A mobile node for a telecommunications system, which telecommunications system comprises one or more routers configured to transmit advertising messages having attribute information, said mobile node comprising:
- reception means for receiving attribute information on one or more network elements from at least one router, said attribute information being received by the at least one router from another network element separate from the network element comprising the at least one router and connected to collect the attribute information, and
- processing means for selecting a serving network element on the basis of said attribute information.
