摘要： Control and/or management plane interactions may be implemented between one or more wireless backhaul links and respective associated access and/or core networks. The control and/or management plane interactions may be implemented in accordance with self-optimization functionalities and may be implemented to perform radio resource management (RRM) for the one or more wireless backhaul links. Packet-based synchronization and/or delay measurement techniques may be implemented to determine estimated values for wireless backhaul induced delay. The delay estimation information may be used by one or more devices in a wireless communications network, such as a packet data network gateway (PGW), a small cell gateway (SC GW), or an access point (AP), such as a small cell access point (SC AP). Delay estimation for wireless backhaul links may be implemented in accordance with PTP message replication and/or side-channel signaling, dual synchronization with GPS and PTP signaling, and/or timestamping.

摘要： Systems and methods for integrating bandwidth management (BWM) equipment into a network in order to manage the use of bandwidth over multiple radio access technologies (RATs) relating to communications between a wireless transmit receive unit and a mobile core network (MCN). When integrating itself into the network, a BWM server may be placed between a MCN and an femto access point. In order for WTRUs to communicate with the MCN through the femto access point and a BWM server, a BWM server may need deep packet inspection capabilities.

摘要： A method and apparatus for maintaining a connection between a wireless transmit/receive unit (WTRU) and a blanket wireless local area network (BWLAN) are described. An inter-working function (IWF) entity in a given network access point (NAP) of the BWLAN maintains lists of WTRUs in respective states. Furthermore, the given NAP maintains a list of neighbor NAPs, and operates in accordance with a selected WTRU mobility protocol. The states may include a “not aware” (NA) state in which the given NAP is actually not aware of a particular WTRU, an “active transmit” (AT) state in which the given NAP is actively transmitting to a particular WTRU, and a “neighbor range” (NR) state for WTRUs indicated in an update report from neighbor (URN) message that the given NAP was not aware of. The WTRU mobility protocol may be a push mobility protocol or a poll mobility protocol.
