Abstract: The techniques introduced here provide for network assisted device-to-device communication for peer-to-peer applications. The techniques include registering a user's peer-to-peer application identifier with a peer-to-peer application server, registering a peer-to-peer application with a device-to-device server, sending a peer-to-peer service request to the peer-to-peer application server, and receiving network assistance in discovering a peer with the desired P2P content/service and establishing a device-to-device communication arrangement for exchange of peer-to-peer services.

Abstract: Wireless communication devices may directly communicate within groups of wireless communication devices using Layer-2 communications to implement “push-to-talk” type applications. In one implementation, a method may include generating a floor request signaling message to take control of a communication channel for a group. After transmitting data relating to the communications, a floor release signaling message may be generated and transmitted a number of times.

Abstract: Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g., through a cellular network) to direct mode communications (e.g., a communication path directly between two communication devices). For example, in switching from an infrastructure mode communication path to a direct mode communication path, a method may include: determining a public-facing address corresponding to the infrastructure path; replacing, for a packet that is to be transmitted over the direct mode communication path to a second communication device, a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.

Abstract translation: 当通信设备从通信网络基础设施（例如，通过蜂窝网络）转换到直接模式通信（例如，直接在两个通信设备之间的通信路径）时，可以维持会话连续性。 例如，在从基础设施模式通信路径切换到直接模式通信路径时，方法可以包括：确定与基础设施路径相对应的面向公众的地址; 将要通过直接模式通信路径发送的分组替换为具有确定的公共地址的分组的源地址字段; 并且通过分别通过直接模式通信路径封装与第一和第二通信设备相对应的源和目的地地址字段的分组。

Abstract: Techniques described herein may provide for device discovery of direct communication paths, to enable direct mode communication, between communication devices. The discovery of the communication paths may be based on identifiers that may be defined at the application level and included in device discovery requests. In one implementation, the identifiers may be SIP-URIs (session initiation protocol (SIP)-uniform resource identifiers (URIs)).

Abstract: Technology for as radio access network (RAN) node that is operable to report user plane congestion (UPCON) is disclosed. The RAN node may include computer circuitry configured to receive, from a Core Network (CN), an information element (IE) including UPCON related Policy and Control Charging (PCC) information. The RAN node may identify a location of an UPCON event, at the RAN node, based on an UPCON event trigger included in the UPCON related PCC information. The RAN node may report Radio Access Network Congestion Information (RCI) about the UPCON event to one or more network elements in the CN.
