Various embodiments of systems and methods that provide more power save multi-poll (MPSMP) indication solutions to improve both the channel access efficiency and power saving capability. In one embodiment, for each address destination, a PSMP frame (the multi-poll frame) provides a time interval during which the client station is to receive traffic (downlink time or DLT) and the time interval during which this client station can transmit (uplink time or ULT). At any other time, such a client station may go to sleep and save power, until the next PSMP arrives. The uplink times are scheduled after the downlink times, for specific efficiency reasons. One embodiment of an MPSMP indication method enables the PSMP frame indicate whether another PSMP frame is to follow at the end of the uplink and downlink periods (or schedule) as described in the current PSMP frame, through an MPSMP indication. If the MPSMP indication is set, the client station knows to wake up immediately after the scheduled uplink and downlink times of this PSMP to receive the next PSMP.

A technique propagates reachability information for a tail-end node of a traffic engineering (TE) label switched path (LSP) to a head-end node of the TE-LSP in a computer network. The TE-LSP preferably spans multiple domains of the network such that the tail-end node resides in a domain that is different (remote) from the domain of the head-end node. The inter-domain information propagation technique employs an Interior Gateway Protocol (IGP) to transmit the remote reachability information from a target node residing in the same domain as the tail-end node to the head-end node. The head-end node uses the remote information to calculate routes, i.e., address prefixes and associated attributes, reachable from the tail-end node for insertion into its routing table.

In preferred embodiments, a wireless network system features buffering of data packets transmitted to mobile nodes. The system is transparent to the mobile node, so that the mobile node is not required to request service from the network, or negotiate service parameters with the network. An EAPOL-Start and binding update messages initiate and terminate the buffering, and also commence pre-authentication and smooth handoff reporting, respectively.

A method of encapsulating TDM data into individual data packets for transmission across a packet network includes delineating the TDM data into one or more signaling multiframes (106S), wherein each signaling multiframe (106) includes one period of a periodic signaling pattern, and appending a header (RT) associated with the individual data packet to each of the signaling multiframes (106s) of TDM data.

A communications system may include data storage devices each using at least one of a plurality of different operating protocols. Further, at least one of the data storage devices may operate using multiple operating protocols. The system may also include mobile wireless communications devices for accessing the at least one data storage device, and each may use at least one of the plurality of operating protocols. Moreover, the system may further include a protocol interface device. The protocol interface device may include a front-end proxy module for communicating with the plurality of mobile wireless communications devices using respective operating protocols. The protocol interface may also include a protocol engine module for communicating with the data storage devices using respective operating protocols. The protocol engine module may also select a desired operating protocol for communicating with the at least one data storage device from the multiple operating protocols.
摘要:
A method and apparatus for enhanced uplink multiplexing are disclosed. A set of combinations of MAC-d flows (and/or logical channels) that are allowed to be multiplexed within a MAC-e PDU is defined for a WTRU. The WTRU MAC-e entity selects a combination among a set of allowed combinations for multiplexing MAC-d flows for each MAC-e PDU. Certain MAC-d flow combinations may be defined that can not be blocked from transmission even when the WTRU is in a transmit power restricted state. The amount of data from each logical channel or corresponding MAC-d flow that can be multiplexed within a MAC-e PDU may be defined to ensure guaranteed data rates. When the WTRU is in a restricted power condition, an indication of the restricted power condition may be passed to the Node-B with the EU transmission.
