Abstract: A method for mobile management entity (MME) selection includes receiving at a base transceiver station (BTS) a message from each of multiple MMEs including information for advertising functionalities of each of the MMEs. The functionalities include at least one type of communications session supported by each of the MMEs. The method also includes receiving at the BTS a message from a user equipment (UE) to request for a communications session. The request message includes session type information indicating a type of session requested by the UE. At least one of the MMEs is capable of serving the requested type of session. The method further includes generating a list of candidate MMEs capable of serving the requested type of communications session from the MMEs by matching the session type information with the capability information, and selecting a serving MME from the list based on the information relating to the advertised functionalities.

Abstract: A method is provided in one example embodiment and may include determining that a periodic timer for a user equipment (UE) is about to expire; communicating to an application service, prior to expiration of the periodic timer for the UE, an indication associated with an availability of the UE to receive data from the application service; and communicating the data from the application service to the UE upon receiving the indication. In some cases, the method can include registering, by the application service, to receive the indication from a Mobility Management Entity (MME) or a serving General Packet Radio Service (GPRS) support node (SGSN), wherein the registering is performed via a service capability exposure function (SCEF) in communication with the MME or the SGSN and the application service.

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: Systems and methods are provided for avoiding excessive paging through messaging-based solutions on a mobile network that supports multiple radio access technologies (RATs), such as both Long Term Evolution (LTE) and Global System for Mobile Communications (GSM)/Enhanced Data Rates for GSM Evolution (EDGE)/Universal Mobile Communications System (UMTS) technology, even in situations where the present location of the UE is not known. Preventing paging in access networks where the UE is not present ensures efficient use of radio resources in the paging channel and reduces signaling load on other interfaces. In one embodiment, a user equipment (UE) is simultaneously connected to a Serving General Packet Radio System (GPRS) Support Node (SGSN) and a Mobility Management Entity (MME). By using signaling between the SGSN and MME, the location of the UE may be tracked without requiring unnecessary paging, even when the UE is in IDLE mode or is inactive.

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。
