摘要:
Mobile IP (MIP) protocol may be used to transfer a communication flow between nodes. An indication to transfer the communication flow is received at a first node, and the first node sends a communication flow transfer request via mobile internet protocol. The request is received by a network device. The network device forwards the request for delivery to the second node. The network device receives a response to the request originated from the second node via mobile internet protocol, and instructs a correspondence node to transfer the communication flow to the second node. Upon receiving a response indicating that the communication flow transfer request has been accepted, the first node terminates the communication flow at the first node. The second node resumes the transferred communication flow.

In an IP-based cellular telecommunications network, such as for example in a Code Division Multiple Access (CDMA) 2000 cellular telecommunications network, a method, a system and a Packet Data Serving Node (PDSN) for registering a Mobile Node (MN) with the PDSN. Once a Point-to-Point Protocol (PPP) connection is established between the MN and the PDSN, a PPP timer is started, the PPP timer being set to expire after a predetermined period of time. A Mobile Internet Protocol (MIP) registration takes place between the MN and the PDSN. The PDSN detects if the MIP registration is successful and if so, resets the PPP timer to a substantially higher value and the PPP session continues until one of the involved parties terminates it. If the MIP registration is not successful, the PDSN further detects if a new MIP registration request is received before the expiration of the predefined period of time, and if so, the PDSN resets the PPP timer again to the predefined period of time. Otherwise, if a new MIP registration request is not received before the timer expiration, the PDSN terminates the PPP connection. The PDSN comprises the PPP timer, an RP stack for supporting an RP connection, a PPP stack activated for the duration of the PPP connection, and a foreign agent for performing the MIP registration of the MN, which may be implemented using software or hardware modules, or a combination thereof.

Systems and methods are provided for using a light weight protocol (LWP) and protocol agent in a network communication system. A protocol agent receives a message in LWP from an end node. The message in LWP is directed to a destination network node that uses a network protocol that the end node is incapable of supporting, such as Hypertext Transfer Protocol (HTTP), Real Time Streaming Protocol (RTSP), Session Initiation Protocol (SIP) or other network protocols. The protocol agent determines a network protocol to map the message to, and generates a message in the determined network protocol based on the received LWP message. The protocol agent then sends the generated message to the destination network node.

Embodiments contemplate one or more socket application program interface (API) extensions that may provide one or more Internet Protocol Address lists. Embodiments may include determining a state (or status) of one or more available Internet Protocol (IP) addresses. Further, embodiments may include communicating the state (or status) of the available Internet addresses to a Multi Connection Transport Protocol.

A WTRU includes a transceiver and a media independent handover (MIH) function (MIHF), which transmits via the transceiver a request to set information in an external device. The MIHF receives a response to the request to store the information in the network node indicating that the request to store the information in the network node was successful.

A wireless transmit/receive unit (WTRU) may receive a broadcast service via a broadcast system. The broadcast service may be handed over from the broadcast system to a second broadcast system, and the WTRU may receive the broadcast service via the second broadcast system. The WTRU and/or the broadcast system may change broadcast service configuration parameters (such as video encapsulation format, video codec, frame rate, audio codec) to receive and/or display broadcast service data received via the second broadcast system. Additionally, a WTRU may receive a broadcast service via a broadcast system that includes more than one broadcast transmission network. The broadcast service may be handed over from a first broadcast transmission network in the broadcast system to a second broadcast transmission network in the broadcast system. The WTRU may change broadcast service configuration parameters to receive and/or display broadcast service data received via the second broadcast transmission network.
摘要:
A method and an apparatus for supporting handover between a first network supporting proxy mobile Internet Protocol (IP) (PMIP) and a second network supporting mobile IP (MIP) are disclosed. A PMIP entity in the first network may perform home agent (HA) discovery such that the PMIP entity may select an HA that responds with a pre-determined code indicating that a binding entry for the WTRU exists in the HA. The PMIP entity may store the HA IP address in an authentication, authorization, and accounting (AAA) server. The PMIP entity may retrieve the HA IP address for the WTRU from the AAA server when the WTRU is readmitted, and perform a binding update using the HA IP address. A media independent handover (MIH) client may trigger an HA discovery to obtain an HA IP address without performing MIP registration. The MIP client may retain the HA IP address when disabled.

A method and apparatus for bandwidth aggregation for an Internet protocol (IP) flow are disclosed. A sender may split IP packets on a single IP flow, and transmit the IP packets to a receiver via at least two interfaces. The sender splitting the IP packets over multiple interfaces may not send any signaling to the receiver. Alternatively, the sender may send information to the receiver for configuring distribution of the IP packets over multiple interfaces. The information may be carried on a binding update message, a binding acknowledgement message, or a binding refresh request message. The IP packets may be split and transmitted by a logical interface that sits between an IP layer and a layer 2, or by a bandwidth aggregation (BWA) middleware located between a transmission control protocol (TCP) layer and an IP layer.
摘要:
Systems and methods are provided for routing internet protocol (IP) traffic flows when connected to a mobile network and a local network. A wireless transmit and receive unit (WTRU) determines whether to offload an IP traffic flow from the mobile network to the local network based on the destination address of the IP traffic flow. When the destination address is local, the WTRU routes the IP traffic flow through local network. The WTRU determines whether to offload IP traffic to the local network based on the stability state of the local network When the local network connection is sufficiently stable for the application associated with the IP traffic, the IP traffic is offloaded to the local network by selecting the local IP address as the source IP address.
