摘要： Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.

摘要： In one embodiment according to the present disclosure, a system for implementing handover of a mobile IP session in a cellular communication network generally includes a processor and a memory for storing one or more context information rules associated with an access terminal. The processor is operable to receive a registration request message from the target radio network controller and in response to receipt of the registration request message, transmit a context information request message to query context information from an anchor IP gateway. The processor is also operable to receive a context information response message from the anchor IP gateway and apply the context information response message to the mobile IP connection. The context information response message including at least one context information rule that is associated with the access terminal.

摘要： In one embodiment, a first node receives data associated with a mobile node. The mobile node includes a plurality of sessions associated with it. For example, the plurality of sessions may be associated with flows for different services, such as voice over IP. A session for the data is determined out of a plurality of sessions. Labels may be provided that correspond to sessions in the plurality of sessions and a label is then determined for the session. The data is sent to the second node in a packet that includes the label. The packet is sent using a label switched path (LSP) in a multi-protocol label switching (MPLS) network. When the second node receives the data, it uses the label to determine a performance treatment to apply to the data. For example, different labels may correspond to the different sessions and different sessions may be associated with different quality of service (QoS) levels.

摘要： Particular embodiments provide an optimal allocation of a bearer manager or home agent. In one embodiment, a message is received from a mobile node requesting access to a visiting network that is different from a home network for the mobile node. An authentication request is sent to the home network requesting authentication for access. The authentication request indicates that a home agent has not been assigned. The home AAA server then sends a response that indicates the visiting AAA server can assign a home agent for the mobile node. The visiting AAA server then assigns a home agent that is optimally determined. The visiting home agent is different from a home agent that is found in the mobile node's home network. When a registration request is received, an IP gateway may send the registration request to the visiting home agent, which may not be sent back to the home network.

摘要： Techniques for allowing a home agent to provide location/presence-based services are provided. In one embodiment, a point of attachment of an access network receives a discovery request from a mobile node. A mobile node is associated with a home agent in a home network different from the access network. Location/presence-based information is determined at the point of attachment. The location/presence-based information is added to a registration request at the layer 3 protocol layer. The registration request is then sent from the point of attachment to the home agent. When the registration request is received at the home agent, the home agent parses the registration request to determine the location/presence information from the request. The home agent then performs a location/presence service using the location/presence information.
