Abstract:
Providing a mobility key for a communication session for a mobile station includes facilitating initiation of the communication session. A master key for the communication session is established, where the master key is generated at an authentication server in response to authenticating the mobile station. A mobility key is derived from the authentication key at an access node, where the mobility key is operable to authenticate mobility signaling for the communication session.
Abstract:
A method for distributing information in a network environment is provided that includes receiving one or more packets from a communication flow and recognizing a universal generic identification (UGI) (14a, 14b) associated with the communication flow. The UGI corresponds to an end user (12a, 12b) that is associated with the communication flow. The UGI is operable to enable a service for the end user in a first network and a second network, the first and second networks being different, whereby either the first network or the second network operates as a home network for the end user.
Abstract:
Requesting a network resource includes facilitating a communication session between a mobile node and an endpoint. A trigger event is received at a first anchor point associated with the mobile node. The trigger event indicates that reservation of a network resource is being requested for the communication session. A second anchor point associated with the endpoint is identified. Reservation of the network resources for the communication sessions is initiated over a tunnel between the first anchor point and the second anchor point.
Abstract:
Facilitating node mobility includes facilitating a communication session for a mobile node communicated along a first communication path. A first anchor point manages context information for the communication session, where the context information comprises information for supporting the communication session. A command to transfer the context information to a second anchor point is received from a home agent. The second anchor point is operable to facilitate communication of the communication session along a second communication path. The context information is transferred in response to the command.

Abstract:
Obtaining neighborhood information for a cell includes establishing the presence of a mobile node in a first cell having a first cell site. A communication session for the mobile node is facilitated. Neighborhood information is determined in response to facilitating the communication session. The neighborhood information describes a second cell having a second cell site. The neighborhood information is recorded in a neighborhood information record.
