Abstract: Techniques are describe for establishing an overall label switched path (LSP) for dynamic load balancing of network traffic being sent across a network using the a resource reservation protocol such as Resource Reservation Protocol with Traffic Engineering (RSVP-TE). The tunnel may be a single RSVP-TE Label Switched Path (LSP) that is configured to automatically and dynamically load balance network traffic across different sub-paths of the RSVP-TE LSP over the network. The ingress device of the overall multi-path LSP can analyze traffic statistics to determine when a network traffic demand differs from a currently reserved bandwidth of the overall multi-path LSP by at least a threshold amount, and can automatically add or remove a sub-path from the overall multi-path LSP to adjust capacity of the overall multi-path LSP to correspond to the currently reserved bandwidth.

Abstract: A method and apparatus for home Node-B (HNB) mobility with a local IP access (LIPA) packet data network (PDN) connection are described. A target home node-B (HNB) may receive a handover request message from a source HNB to handover a wireless transmit/receive unit (WTRU). A path switch request may be transmitted to a local gateway (LGW) to change a downlink data path towards the target HNB in response to the handover request message. The LGW may act as a mobility management and local mobility anchor for the handover; and informing an HNB gateway (GW) about the handover so that the downlink data path for core network (CN) traffic is modified towards the target HNB.

Abstract: A dual-mode device may compute an expected time instance of arrival of a first beacon based on prior received beacons. If the first beacon is received at an actual time instance which is in variance with the expected time instance, the device re-computes a sequence of future time instances of arrival of respective future beacons and schedules a sequence of station windows, with each station window to cover the corresponding future time instance of the sequence of future time instances and to have a desired first period. The dual-mode device operates in station mode in the sequence of station windows and in the AP mode in a sequence of AP windows, wherein each station window of the sequence of station windows is operated alternately with each AP window of the sequence of AP windows in a TDM manner, with each AP window having a desired second period.

Abstract: A method and apparatus for searching for closed subscriber group (CSG) cells are described. A wireless transmit/receive unit (WTRU) transmits, to a network of CSG cells, a measurement/cell-search gap request message including a cause value having at least one bit that indicates whether the request message was transmitted due to a manual cell search command or a WTRU autonomous determination. The WTRU receives a measurement/cell-search gap allocation message from the network in response to the measurement/cell-search request message. The WTRU also may determine whether it has a discontinuous reception (DRX) gap that is long enough to read a master information block (MIB) and a system information block (SIB) of a neighboring CSG cell. If the DRX gap is not long enough, the WTRU may transmit a measurement/cell-search gap request message to the network, or autonomously tune away from a cell currently serving the WTRU to read the MIB and SIB.

The node devices of the first group can communicate with a node device in a second cluster adjacent to the first cluster. The selection device performs transmission and reception of a report frame that reports an identifier of a node device included in the first group. The selection device selects from the first group a first relay device that relays a relay frame used for a communication between a node device in the first cluster and a node device in the second cluster. The first relay device determines anode device adjacent to the first relay device to be a second relay device that relays the relay frame to a node device in the second cluster.

Abstract: Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated.
