Abstract
A method and system for selectively including a device-ID within a Mobile-IP registration request. A foreign agent, AAA server or other entity decides, based at least in part on a user-ID carried in a Mobile-IP registration request from a mobile node, whether to insert a device-ID of the mobile node into the registration request. In response to a decision to insert the device-ID, the foreign agent or another entity inserts the device-ID into the registration request and sends the request, including the device-ID, along to a Mobile-IP home agent.
Claims21
In a Mobile-IP communication system in which a foreign agent receives from a mobile node a Mobile IP Registration Request (MIP RRQ) carrying a user-ID, and the foreign agent sends the MIP RRQ thereafter to a Mobile IP home agent to seek Mobile IP registration of the mobile node, a method comprising the following functions carried out after receiving the MIP RRQ at the foreign agent:
- making a determination, based on the user-ID, that the foreign agent should insert a device-ID of the mobile node into the MIP RRQ;
- in response to the determination, the foreign agent inserting the device-ID into the MIP RRQ;
- and
- the foreign agent then sending the MIP RRQ, containing the device-ID, to the home agent.
In a Mobile-IP communication system in which a foreign agent receives from a mobile node a Mobile IP Registration Request (MIP RRQ) carrying a user-ID, and the foreign agent sends the MIP RRQ thereafter to a Mobile IP home agent to seek Mobile IP registration of the mobile node, the improvement comprising:
- data storage in the foreign agent;
- program logic stored in the data storage and executable by a processor of the foreign agent, after receiving the MIP RRQ at the foreign agent, (i) to make a determination, based on the user-ID, that the foreign agent should insert a device-ID of the mobile node into the MIP RRQ, (ii) to insert the device-ID into the MIP RRQ in response to the determination, and (iii) to send the MIP RRQ, including the device-ID, to the home agent.
In a Mobile-IP communication system in which a foreign agent receives from a mobile node a Mobile IP Registration Request (MIP RRQ) carrying a user-ID, the foreign agent then sends to an authorization server an authorization request message carrying the user-ID and receives in response from the authorization server an authorization response message, and the foreign agent then sends the MIP RRQ to a Mobile IP home agent to seek Mobile IP registration of the mobile node, the improvement comprising:
- means at the authorization server for deciding, based on the user-ID, to include in the authorization response message an instruction directing the foreign agent to provide a device-ID of the mobile node in the MIP RRQ, and for responsively including the instruction in the authorization response;
- and
- means at the foreign agent for reading the instruction in the authorization response and responsively providing the device-ID in the MIP RRQ that the foreign agent sends to the home agent.
A method comprising the following steps:
- receiving a Mobile-IP registration request that is being conveyed from a mobile node to a home agent;
- making a decision, based at least in part on a user-ID associated with the registration request, to include a device-ID of the mobile node in the registration request;
- responsive to the decision, including the device-ID in the registration request;
- and
- sending the registration request, including the device-ID, along to the home agent.
