Abstract: A RAN includes a first coverage area and a second coverage. An access terminal, initially engaged in a call via the first coverage area, determines a call type of the call and adjusts, based on the determined call type, one or both of a first value for a first threshold and a second value for a second threshold. While engaged in the call, the access terminal determines that (i) a signal strength of a signal received from the first coverage area is less than the first threshold, and (ii) a signal strength of a signal detected from the second coverage area is greater than the second threshold. In response to making both determinations, the access terminal hands off the call from the first coverage area to the second coverage area.

Abstract: Various embodiments are described for redirecting a mobile station via a traffic channel. In one embodiment, a first RAN receives a request from a mobile station to establish a traffic channel between the mobile station and the first RAN for use in a communication session. The first RAN makes a determination to not establish the communication session, but nevertheless establishes the requested traffic channel after making the determination. Then, without establishing the communication session, the first RAN redirects the mobile station via the established traffic channel to a second RAN. By establishing the traffic channel even though the RAN may be unable (or unwilling) to allow the mobile station to establish the communication session, the RAN is able to control the behavior of the mobile station in the event that the RAN cannot establish the requested communication session.

Abstract: A radio access network (RAN) may be configured to identify a set of wireless coverage areas in which to transmit inter-frequency search directives. Identifying the set of coverage areas may involve determining which of the coverage areas defined by the RAN have threshold weaker coverage on one carrier frequency than on another carrier frequency of that coverage area. For each coverage area of the set, the RAN may identify one or more WCDs operating in the coverage area that are operating on the coverage area's carrier frequency that has the weaker coverage. Based on the identifying of the WCDs, the RAN may send to each identified WCD an inter-frequency search directive to cause the WCD to scan for and report to the RAN a measurement of coverage on one or more carrier frequencies other than the carrier frequency on which the WCD is currently operating.

Abstract: A method and corresponding system for management of neighbor scanning in a cellular wireless communication system is disclosed. A radio access network (RAN) sends, and a mobile device receives, a neighbor list update message containing a plurality of different neighbor lists each listing available neighboring coverage areas communicating on respective communication channels. While the mobile device is engaged in a call, the mobile device selects one of the neighbor lists based on a service type of the engaged call. The mobile device scans the neighbors listed in the selected neighbor list for signal strengths sufficient to trigger a hand off. The mobile device sends a report indicating measured signal strengths of signals from the neighbors to the RAN, which then instructs the mobile device to hand off the engaged call.
