System and method for reducing paging in UTRAN/GERAN/E-UTRAN networks when idle signaling reduction is active

摘要

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.

1. A method comprising:
detecting a failure of a serving gateway (SGW) for a mobile device at a first core network node, the first core network node to communicate with the mobile device via a first radio access technology; and in response to the detecting the failure of the SGW, determining, by the first core network node, whether to page the mobile device based, at least in part, on a stored state of the mobile device with respect to a second core network node, the second core network node to communicate with the mobile device via a second radio access technology.
