Methods and apparatus for triggering roaming in a mobile network device are disclosed. A speed of the network device is detected. One or more maximum/minimum trigger values corresponding to one or more trigger events are ascertained at the speed of the network device. One or more trigger counters associated with the one or more trigger events are maintained. Roaming of the network device is triggered when one of the trigger counters associated with one of the trigger events is equal to or exceeds (or is less than or equal to) one of the trigger values corresponding to the trigger event at the speed of the network device.

Methods and apparatus for reducing roaming latency in a mobile node

The present invention communication network system and method facilitates authentication and registration in a communication network as mobile nodes move from one geographical region to another. Multiple wireless domain services (WDSs) share client authentication information permitting relatively seamless roaming between subnets with minimal interruptions and delays. In one embodiment, a wireless domain service network communication method is performed utilizing partial authentication processes. A mobile node engages in an authentication protocol with a first wireless domain service (WDS) access point in a first subnet. The authentication credentials are forwarded to a second wireless domain service in a second subnet if the authentication protocol is successfully completed. The forwarded authentication credentials are utilized to authenticate the client entering the service area of the second wireless domain service in the second subnet. The authentication credentials can be 'pushed' or 'pulled' from the first wireless domain service to the second wireless domain service.

Inter subnet roaming system and method

A method for dynamic configuration of a mobile access point. A position of the mobile access point is determined based on a position determination system. A region is identified based on position. Configuration information associated with an application of the mobile access point is automatically updated based on the region.

Method for dynamic configuration of a mobile access point

A technique offloads a central directory services (CDS) function from a mainframe of an advanced peer-to-peer networking (APPN) network to a light-weight directory access protocol (LDAP) Accessible Directory Services (LADS) residing off the mainframe on another dissimilar network. At least one network node of the APPN network is configured with LDAP interface that enables communication with the LADS. The LADS is configured to provide CDS functionality on the dissimilar network, such as a Transmission Control Protocol/Internet Protocol network. In response to a request from a node on the APPN network, the LDAP interface accesses the LADS using the LDAP protocol in accordance with a client-server architecture.
