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 translation: 提供了系统和方法，以避免在支持多种无线电接入技术（RAT）的移动网络上通过基于消息的解决方案的过度寻呼，诸如长期演进（LTE）和全球移动通信系统（GSM）/增强数据速率 用于GSM演进（EDGE）/通用移动通信系统（UMTS）技术，即使在UE的当前位置未知的情况下也是如此。 防止在不存在UE的接入网络中的寻呼能够有效地利用寻呼信道中的无线电资源，并减少其他接口上的信令负载。 在一个实施例中，用户设备（UE）同时连接到服务通用分组无线电系统（GPRS）支持节点（SGSN）和移动性管理实体（MME）。 通过在SGSN和MME之间使用信令，即使当UE处于空闲模式或不活动时，可以跟踪UE的位置而不需要不必要的寻呼。

Abstract: This disclosure relates to a system and method for dynamically managing load on network devices in a distributed manner. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network to accommodate increased data traffic is neither desirable nor practical. One way to accommodate increased data traffic is by utilizing network resources more efficiently. This disclosure provides systems and methods for efficiently utilizing network resources by dynamically configuring the network in a distributed manner based on real-time load information.
