    Abstract: Managing packet data network (PDN) connectivity for a device. PDN connectivity to a local gateway L-GW can be managed at an access point with which the device is communicating based at least in part on received PDN connectivity parameters, (e.g. list of Access Point Names, APNs, list of Closed Subscriber Groups, CSGs, indication on whether Local Internet Protocol Access, LIPA, or selected IP Traffic Offload, SIPTO, is allowed, etc). The PDN connectivity parameters can include access points, related closed subscriber groups, public land mobile networks, etc., from which a device (MME) can request a PDN connection. The PDN connectivity parameters can be specific for the device and/or for one or more access point names. In addition, a subscription server or other core network device can communicate the PDN connectivity parameters to the device and/or the device can receive PDN connectivity parameters as a result of a failed PDN connection attempt to an access point.

    Abstract: Techniques for transporting messages for location services (LCS) are described. A Mobility Management Entity (MME) may have a location session with an Evolved Serving Mobile Location Center (E-SMLC) to provide location services for a User Equipment (UE). The UE may exchange LCS-related messages with the E-SMLC to obtain location services. In an aspect, LCS-related messages exchanged between the UE and the E-SMLC may be encapsulated in Non-Access Stratum (NAS) messages and transported via the MME and a base station. In another aspect, a routing identifier (ID) may be used to associate messages exchanged between the UE and the MME with the location session between the MME and the E-SMLC for the UE. Each NAS message exchanged between the MME and the UE may include the routing ID, which may enable the MME to associate each NAS message from the UE with the location session between the MME and the E-SMLC.

    Abstract: A multi-party commitment method is provided whereby a joining node uses contributions provided by contributor nodes in a peer-to-peer overlay network to generate a node identifier. The joining node generates a first contribution and sends a join request to an introducer node (or a plurality of contributor nodes), where the join request seeks to obtain one or more contributions for generating the node identifier within an identifier space of the overlay network. A hash of the first contribution may be included as part of the join request. In response, the joining node may receive a plurality of contributions, wherein the contributions are bound to each other and the first contribution by a prior external multi-node commitment operation. The joining node can then generate its node identifier as a function of the first contribution and the received contributions. Consequently, collusion between nodes and malicious manipulation during ID generation can be frustrated.

    Abstract translation: 提供多方承诺方法，由此加入节点使用由对等覆盖网络中的贡献者节点提供的贡献来生成节点标识符。 加入节点生成第一贡献并向引导者节点（或多个贡献者节点）发送加入请求，其中加入请求试图获得用于在覆盖网络的标识符空间内生成节点标识符的一个或多个贡献。 第一个贡献的散列可以作为加入请求的一部分包含在内。 作为响应，加入节点可以接收多个贡献，其中贡献彼此相关并且第一贡献通过先前的外部多节点承诺操作。 随后加入节点可以根据第一贡献和接收到的贡献生成其节点标识符。 因此，ID生成期间节点之间的串通和恶意操作可能会受挫。

    Abstract: Systems and methodologies are described that facilitate supporting multiple access modes for a base station in a wireless communication environment. The base station can leverage hybrid, closed, or open access mode. A whitelist of a mobile device that successfully registers on the base station can be selectively updated to include a CSG ID of the base station (708). For example, the CSG ID of the base station can be added to the whitelist when the base station operates in closed access mode, while adding the CSG ID can be skipped when the base station operates in hybrid access mode. According to another example, the CSG ID can be selectively added based upon a received accept cause value. Additionally or alternatively, a CSG ID and an access mode indicator can be transmitted from a base station to a network node for implementing access control and/or paging optimization at the network node.

    Abstract: A method and apparatus for interworking between push-to-talk over cellular (PoC) systems and instant messagaing (IM) systems is provided. An interworking entity that behaves like a PoC client to a PoC server and as an IM client to the IM server is provided. The interworking entity may be implemented as part of the PoC server or the IM server. The interworking entity listens to talk bursts from the PoC server and when it receives a talk burst the interworking entity sends the message to the IM client via the IM server. In an embodiment, the interworking entity listens to talk bursts or audio clips from the IM server and when it receives them, stores them in a temporary storage memory and converts them to a streaming format. The interworking entity then requests the floor from the PoC server, and, once the floor is granted, streams the stored audio clip or talk burst to the PoC server. The PoC server then distributes the clips to the PoC clients.

    Abstract: Systems and methodologies are described that facilitate fetching a native security context between network nodes in a core network after an inter-system handover of a mobile device. For instance, a mobility message that is integrity protected by a security context (e.g., the native security context, a mapped security context,..) can be obtained at a network node from the mobile device. Further, the network node can send a request to a disparate network node within a core network. The request can include information that can be used by the disparate network node to establish that the mobile device is authenticated. Moreover, the native security context can be received from the disparate network node in response to the request. Accordingly, the native security context need not be recreated between the network node and the mobile device.
