Abstract: An example method is provided in one example embodiment and may include configuring paging parameters for a group of one or more user equipment (UE) based, at least in part, on a group identifier (ID) for the group of one or more UE; communicating the paging parameters to each of the one or more UE of the group; and paging one or more idle mode UE of the group according to the paging parameters to transition the idle mode UE to a connected mode for receiving a group message. In some instances, configuring the paging parameters can include configuring a paging frame and paging occasion for the group of one or more UE based on the group ID; configuring extended paging cycle radio frames for the group of one or more UE; and/or configuring a paging group Radio Network Temporary Identifier for the group of one or more UE.

Abstract: The present disclosure is directed at systems, methods and media for providing QoS differentiation between IP data flows by sorting data packets into bearers. If a first node in a communication network (e.g., a User Equipment or UE) determines that downlink packets received from a second node (e.g., a Packet Data Network Gateway or PDN-GW) via a specific bearer should be given reflective bearer treatment, the first node can be configured to send uplink packets back to the second node via the same bearer. By sending uplink traffic using the same bearer as downlink traffic, the first node can aid in ensuring that the correct QoS for the uplink traffic is used. Downlink packets or bearers can be configured to request reflective bearer treatment through reserved QoS Class Identifier (QCI) values, Allocation and Retention Priority (ARP) values, or through an indicator specifically defined for requesting such treatment.

Abstract translation: 本公开涉及通过将数据分组分类为承载来提供IP数据流之间的QoS差异的系统，方法和媒体。 如果通信网络（例如，用户设备或UE）中的第一节点确定经由特定承载从第二节点（例如，分组数据网络网关或PDN-GW）接收的下行链路分组应被给予反射承载处理， 第一节点可以被配置为经由相同的承载将上行链路分组发送回第二节点。 通过使用与下行流量相同的承载来发送上行流量，第一节点可以帮助确保使用用于上行流量的正确QoS。 下行链路分组或承载可以被配置为通过保留的QoS类别标识符（QCI）值，分配和保持优先级（ARP）值或通过为请求这样的处理而特别定义的指示符来请求反射承载处理。

Abstract: An example method is provided in one example embodiment and may include determining that a user equipment (UE) is approximately stationary for a threshold period of time within a particular geographic area based, at least in part, on a radio access network (RAN) node to which the UE is attached; notifying the UE that the UE has been associated with the particular geographic area; and transitioning the UE into an idle mode from an active mode, wherein the transitioning is performed without notifying a core network that the UE has transitioned to the idle mode. Determining that the UE is approximately stationary can include monitoring mobility signaling from the UE and comparing an amount of time that the UE has been attached to the RAN node with a threshold period of time. The core network can be notified when the UE moves out of the particular geographic area.

Abstract: An example method is provided in one example embodiment and includes receiving, by a user equipment device, a list including at least one location identifier associated with an area for location reporting and an area identifier identifying the area for location reporting. The method further includes receiving a location identifier broadcast by a wireless network element, and determining whether the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The method further includes sending a location reporting message by the user equipment device to a first network node when it is determined that the broadcast location identifier matches the at least one location identifier associated with the area for location reporting. The location reporting message is indicative of the user equipment device either entering or exiting the area for location reporting.
