摘要： A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

摘要： Methods, systems, and instrumentalities are described to obtain application-based connectivity. A wireless transmit receive unit (WTRU) may, in response to a request to access a connectivity-sponsored application, establish a control connection over a first access network for contacting an application connectivity coordinator. The establishment of control connection may include sending an attach request, receiving an IP address for a control link to the application connectivity coordinator, and receiving an IP address. Using the control connection, the WTRU may send an access network discovery request to the application connectivity coordinator. The WTRU may receive, from the application connectivity coordinator, a list of access networks. The WTRU may select a second access network from the list of access networks to access the connectivity-sponsored application.

摘要： 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.

摘要： Systems and methods for dynamic white space management are described. First, local handling of channel queries, in which a channel query by a white space device (WSD) is handled by a local dynamic spectrum management (DSM) server, if the DSM server has all the information necessary for providing a response to the channel query. Second, a search extension, in which a WSDB passes part of a search for available channels to a local DSM server. Third, assisting of an available channel calculation, in which a DSM server provides spectrum sensing information to WSDBs to improve the available channel calculation within the WSDBs. And fourth, dynamic bandwidth management to meet the coexistence requirements. In addition, the content of the messages and procedures that enable the above value-adding functions and interactions with the WSDB systems are described.

摘要： A method and apparatus for secure direct link communication between multiple wireless transmit/receive units (WTRUs) are disclosed. The WTRUs may exchange nonces that are used for generating a common nonce. Group identification information may be generated from at least the common nonce and is forwarded to an authentication server. The authentication server may generate a master key from the group identification information to match WTRUs as part of a key agreement group. The common nonce may be a session key and be refreshed during communication with the second WTRU. A group key encryption key (GKEK) and a group key confirmation key (GKCK) may also be generated based on the common nonce and used to encrypt and sign the master key so that base stations do not have access to the master key. A first WTRU may generate a group direct link temporal key (GDLTK) for communicating with the second WTRU.

摘要： 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.
