Systems, apparatuses and methods for bandwidth management, aggregation and internet protocol (“IP”) flow mobility (“IFOM”) across multiple-access technologies are provided. Included is a method that includes selecting, from a packet data network (“PDN”) connection formed through a plurality of access systems communicatively coupled with a wireless transmit and/or receive unit (“WTRU”), an access system over which to transport a flow of internet protocol (“IP”) traffic to and/or from the WTRU. The method may also include sending, to the WTRU, a request to associate the flow of IP traffic with the selected access system.

Embodiments contemplate one or more techniques for packet filtering. One or more embodiments may apply specific routing and/or forwarding rules on some or each packet when a device has one or more, or multiple, interfaces. Contemplated filtering techniques may be implemented in a module and/or without modifying an IP stack. The contemplated packet filtering techniques may apply to a terminal in uplink and/or downlink as well as to any network node. An incoming packet table may be created using 5-tuple, 6-tuple, and/or tags, among other mechanisms, to support incoming and/or outgoing packet filtering.

A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network.

Embodiments contemplate one or more Session Manager and/or source IP address selection techniques. Embodiments contemplate that a session manager may establish a session in a wireless communication environment based on one or more policies specified by a policy manager. The session manager may also delete the session. For example, the session may be deleted in response to receipt of a request from an application. The session manager may store a session description for the session. The session manager may also perform source IP selection for a data plane. The session manager may also provide an MC transport with IP addresses for negotiating additional sub-flows.

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.

A radio interface layer media independent handover (RIL MIH) client functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers and proxies, informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.
摘要:
A wireless transmit/receive unit (WTRU) may include two or more modems, each configured to link to a different network, and a media independent handover (MIH) client. An application programming interfaces (API) may provide the MIH client with mechanisms to receive information about links, control the modems for handover, discover a MIH server and IP multimedia system nodes, trigger mobile IP handover, etc. If a link has been successfully established, the MIH client may start a MIH session. When the modem indicates that a connection is going to be terminated, the MIH client may activate the second modem for handover. If the first modem indicates that a link parameter has crossed a threshold, the MIH client may send signal measurements to a MIH server. After receiving a media independent handover switch request, the MIH client may initiate handover to the second network.

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.
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.
