Abstract: Systems, methods, and instrumentalities are disclosed for providing Information Centric Networking (ICN) within a network, comprising detecting a request for content from a wireless transmit/receive unit (WTRU) that is in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and providing the content to the WTRU. A request to publish content from a WTRU in the network may include determining, based on content name, whether to publish the content in the network or outside the network, and if the content is to be published in the network, selecting a network element for the WTRU to attach to, wherein the network element is selected without regard to properties of the content requested, and causing the network element to accept the content from the WTRU.

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 disclosed for handling the expiration of an inactivity timer. A cellular communications system may include a gateway (GW), for example, a converged gateway (CGW) or a local gateway (LGW). The GW may intercept a first message from the eNB intended for a mobility management entity (MME). The first message may include an indication to initiate removal of a first bearer and a second bearer. The first bearer may include an SI bearer associated with the eNB and the GW and/or include a Radio Bearer associated with the eNB and a wireless transmit/receive unit (WTRLI). The second bearer may include an S I bearer associated with the GW and a serving gateway (SGW). The GW may determine to maintain the second bearer to maintain a communication path associated with the GW and a WTRU and/or send a second message to the eNB to remove the first bearer.

Abstract: A method and apparatus for performing capture caching in a wireless network. A wireless transmit/receive unit (WTRU) or client device captures data from neighboring devices in the network and internally cache data that was traditionally cached in an edge node. The WTRU reassembles the captured data packets on a condition that the WTRU requests content associated with the captured data packets. If any segments are missing from the captured data packets, only those missing segments are retrieved from the server to repair the data. The reassembly of the data and the repair of missing segments is deferred until the data is needed by the WTRU.

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: Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.

The actions that may be performed when a HeNB may fail may include using S1-AP signaling and/or a signaling interface (e.g., a CMI) to inform a mobility management entity (MME) of the failure, and/or the like.
