摘要：A core network node maintains history information configured to provide a log of location information, and uses the history information to determine whether a wireless terminal is in a location update toggling scenario. The history information can also be used to curtail the toggling scenario. One example mode comprises using the history information to determine whether the wireless terminal is toggling between plural radio access networks of differing radio access technologies. Another example mode comprises using the history information to determine whether the wireless terminal is toggling between a first area update location and a second area update location. Yet another example mode comprises using the history information to determine whether the wireless terminal is toggling between a first core network node and a second core network node.

主权项：1. A method of operating a core network node of a communications system, comprising: maintaining, in the core network node, history information configured to provide a log of location information for a wireless terminal and using the history information to detect whether the wireless terminal is in a location update toggling scenario where location updates by the wireless terminal involving a set of locations exceed a prescribed limit, wherein the history information serves as a log of sites visited by a wireless terminal, and wherein maintaining the history information comprises configuring the history information to comprise an integer N number of records, each record comprising plural fields, wherein record j includes a site identifier field and a time field, the site field indicating a site involved in area update j, and wherein the time field is configured to facilitate a determination of an amount of time the wireless terminal has spent in the site identified for the record j.
