A system for managing wireless communication in view of other potentially interfering wireless signal sources. Signal-related information may be collected from one or more apparatuses that are participating in a network. The information may then be evaluated in order to determine expected signal activity in the environment in which the apparatuses are operating. In some instances the signal activity may then be compared to a scan schedule utilized, for example, to identify legacy apparatuses operating in the environment. This scan schedule may be altered to avoid potential conflicts that may exist with the expected signal activity. The scan schedule may then be communicated to the networked apparatuses.

The present invention provides methods, apparatuses, and systems for supporting emergency calls on a WiMAX access network. According to an embodiment of the invention, a method of providing emergency calling in a WiMAX network is provided. The method includes determining whether a call from a subscriber station (SS) is an emergency call. To enable making an emergency call, the minimum bandwidth required to enable SIP signaling is reserved and required resources are allocated from the access service network gateway (ASN-GW) via a base station (BS).

Systems and methods for providing an efficient network entry for a mobile station in RF communications systems with fully configured and partially configured carriers are described. A distinguishing parameter for fully configured carriers is determined. A mobile station receives a carrier and determines whether a fully configured carrier has been received. The mobile station performs synchronization with a base station using the detected fully configured carrier and completes a network entry procedure. In one method embodiment, the distinguishing parameter is a unique preamble characteristic. In another method embodiment, the fully configured carrier frequency is part of messages broadcast by both the fully configured and partially configured carriers. In yet another method embodiment, the carrier raster for fully configured carriers is distinguishable from the carrier raster for partially configured carriers. Latency is reduced for the network entry process for the mobile stations.

The present invention provides a method and respective entities for avoiding handovers in a ping-pong manner in a communication network. The method comprises comparing, when a handover of a mobile station to a base station is intended, decision criteria of the intended handover with decision criteria of previous handovers of the mobile station to that base station, and deciding on allowing or preventing the intended handover based on the result of the comparison.
