Abstract: User equipment (UE) may include dual mode devices that enable two different radio access technologies (RATs) for connection to wireless communication networks. Recently, these RATs have been used for message splitting in which a message is split into two packet flows, for example, that may enable increased throughput to the (UE). Dynamic mobility management may be provided for the UE by allowing a converged gateway (CGW) to discover the UE. For example, the CGW may identify the UE in communication a first CGW that may be within a first subnet. The CGW may store the identity of the WTRU in the memory. The CGW may transmit the identity of the UE to a second CGW that may be in communication with a second subnet.

Abstract: 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.

Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.

Abstract: Systems, methods, and instrumentalities are described to implement reporting of surveillance information associated with a device. A gateway device may intercept a communication associated with the device. The gateway device may route the communication such that the communication bypasses a core network. The gateway device may report information associated with the communication to a core network entity. The gateway device may receive a command message. The command message may include a request for a surveillance status of the device. The gateway device may send a response message. The response message may indicate a surveillance status of the device. The gateway device may receive an activate surveillance signal for the device. The gateway device may receive a deactivate surveillance signal for the device. Upon receiving the deactivate surveillance signal, the gateway device may stop further reporting.

Abstract: The implementation of Local IP Access (LIPA), “Extended” LIPA (ELIPA), and Selected IP Traffic Offload (SIPTO) for the design of a “Converged Gateway” (CGW) are disclosed. The gateway system may provide various features such as femtocell access to local networks, public Internet, and private service provider networks.

Abstract: A method of dynamic switching of a plurality of carrier loops in a radio receiver. The method comprises: (A) receiving a radio signal from a radio source by using a carrier tracking loop; (B) substantially continuously estimating a signal-to-noise ratio (SNR) of the received radio signal from the radio source; (C) if the signal-to-noise ratio (SNR) of the received radio signal from the radio source is above an initial predetermined threshold, performing carrier tracking of the received carrier signal by an initial carrier tracking loop having an initial accumulation period; and (D) if the signal-to-noise ratio (SNR) of the received radio signal from the radio source falls below the initial predetermined threshold; switching from the initial carrier tracking loop having the initial accumulation period to a subsequent carrier tracking loop having a subsequent accumulation period.
