摘要： Facilitating mobile node mobility includes facilitating at a current access location a communication session for a mobile node. Context information for the communication session is managed, where the context information comprises information for supporting the communication session. A predictive set comprising one or more predicted next access locations is established for the communication session. The context information is transferred to the predicted next access locations prior to the communication session moving to an actual next access location.

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： Techniques for providing wireless services to mobile subscribers using existing broadband network infrastructures are described herein. In one embodiment, in response to a request received at a gateway device from a mobile subscriber over a radio access network (RAN) for accessing a service provider network, the gateway device authenticates the mobile subscriber for accessing the RAN, where the gateway device interfaces the RAN and the existing broadband network. Upon successfully authenticating the mobile subscriber for accessing RAN, the gateway device accesses a network service provider over the existing network to acquire a network address on behalf of the mobile subscriber optionally using at least a portion of credentials derived from the authentication, where the network address allows the mobile subscriber to access the service provider network. Other methods and apparatuses are also described.

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, techniques provide QoS-aware service flow mapping in an access network. A message is received from an access device at a gateway in the access network. The message includes a traffic flow specification. The traffic flow specification may include packet filter information, which is used to install a packet filter to route traffic to the access device. The gateway creates a session and associates the packet filter with it. When an incoming packet is received at the network device, the packet is matched to the packet filter. The incoming packet is then sent to the access device for the session. The traffic flow specification may also specify QoS parameters that are desired. The QoS parameters may then be applied to the packet sent to the access device. The gateway and access device may negotiate to determine a QoS to apply.

摘要： Techniques for security association management on a home and foreign agent are described. In one embodiment, in response to a first mobile network registration request from a mobile node, a remote authentication facility is accessed to retrieve a security association for the mobile node for authenticating and providing a first network connectivity to the mobile node, wherein the security association is associated with a lifespan. The security association is inserted in a local security association database (SADB) to create a security association entry, wherein the security association entry includes the lifespan. A second mobile network registration request from the mobile node after the first connectivity is terminated is received and the security association entry in the local SADB that corresponds to the mobile node is used to provide authentication of the mobile node without having to access the remote authentication facility again if the lifespan associated with the security association entry is valid.

摘要： Techniques for Mobile IP bulk registration revocation are described herein. According to one embodiment, a first mobile agent of a mobile IP network sends a registration revocation message to a second mobile agent of the mobile IP network. The registration revocation message includes information identifying multiple home IP addresses of multiple mobile nodes whose registrations are to be revoked. In response to the registration revocation, the second mobile agent terminates bindings of services associated with multiple mobile nodes identified by the multiple home IP addresses and sends an acknowledgement message to the first mobile agent. Other methods and apparatuses are also described.
