Abstract: 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.

Abstract: Authenticating a registration request from a mobile node includes an authenticator operable to facilitate a communication session for the mobile node. Access authentication to provide the mobile node access to an Internet Protocol (IP) network is facilitated. A mobility key is obtained from the access authentication. A registration request is received from the mobile node, and is authenticated using the mobility key.

Abstract: Assigning an access terminal identifier to a mobile node includes receiving a request at an access terminal home agent of a radio access network. The request requests an access terminal identifier for the mobile node. An access terminal identifier is assigned to the mobile node. The access terminal identifier identifies a communication session of the mobile node, and is assigned according to an Internet Protocol procedure for assigning an address. The access terminal identifier is provided to the mobile node.

Abstract: 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.

Abstract: A system and method is provided for authenticating access in a mobile wireless network. The system and method comprise exchanging an extensible authentication protocol (EAP) packet with an access terminal over a high rate packet data radio link and a signaling interface through a radio access network, encapsulating the EAP packet in an authentication authorization and accounting (AAA) packet, and sending the AAA packet to an authentication server for authentication.

Abstract: 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.

Abstract: 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.

Abstract: In one embodiment, during an authentication process between a network device and an access terminal, an authentication message for access to the network is received. The network device is configured to allow access to an IP network. The network device determines one or more capabilities of the access terminal from the authentication message. An action is then performed based on the one or more capabilities of the access terminal. The action may include using the capabilities to set up a session with the access terminal. Also, the network device may send its own capabilities to the access terminal in an authentication response. Accordingly, a capability negotiation between the access terminal and network device may be provided during an authentication process. This may facilitate a faster session setup as capabilities are exchanged during authentication can be used in the configuration of the session.

Abstract: 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.

Abstract: An invention is disclosed that optimizes resource management within a PDSN. This is accomplished through the modification of functions of a AAA server. Specifically, when a node (e.g., mobile node) is authenticated by a AAA server in response to a request by a target PDSN to which the node has roamed, the AAA server may send a disconnect request message to a source PDSN indicating that the node has moved from the source PDSN. In this manner, the source PDSN is notified that it should terminate its session with the node and release resources associated with the session (e.g., PPP session). The source PDSN may then send a message to the AAA server indicating whether the session was successfully terminated (and whether the resources associated with that session were released).

Abstract: A system and method places signaling message frames in a traffic channel carrying voice frames so that the signaling message transmission does not seriously impact voice quality. This is accomplished by producing a first stream of voice encoded packets and a second stream of signaling message packets. The signaling message packets are prioritized in the second stream relative to the voice encoded packets in the first stream. An arbitration element arbitrates between the voice encoded and prioritized signaling message packets, which are multiplexed as a function of this arbitration. The multiplexed voice encoded and prioritized signaling message packets are then transmitted.

Abstract: A priority access channel assignment system and a messaging protocol allow wireless mobile stations to place calls having differing priority levels. A mobile station originates a call, which may automatically include a request for priority access or may require manual intervention by the user to request priority access. If system resources are unavailable to process the call immediately, the origination message is processed by a base station and a mobile switching center using a plurality of messaging protocols to determine the time at which the call was originated and a priority level associated with the call. Based on the priority level and arrival time, the base station places the call in an appropriate position within a queue. Higher priority calls are placed in a higher position in the queue than lower priority calls. Calls having identical priority are placed in the queue in order of the time of arrival.

Abstract: A method of transparent call discrimination includes providing a call discrimination data message within a Caller ID message frame structure of an outgoing call from a call originating equipment. A type of call on an incoming telephone line of a call receiving equipment is discriminated in response to the call discrimination message, wherein the type of call is discriminated prior to an occurrence of an OFF-HOOK state of the telephone line. An appropriate device of the call receiving equipment is then activated in response to the type of call, in preparation for responding to the incoming call. Lastly, the incoming call is routed to the appropriate device in response to the discriminated type of call at the occurrence of the OFF-HOOK state. An apparatus for transparent call discrimination is also disclosed.
