Abstract: In a wireless communication network, an access node controller determines data throughput over a target access node. A source access node wirelessly exchanges user data with User Equipment (UE) and determines data throughput. The source access node receives signal parameters for the source access node and target access node from the UE. The source access node compares the signal parameters and responsively transfers a handover request that indicates the target node and the UE throughput over the source node. The access node controller receives the handover request and compares the source throughput to the target throughput to determine a handover value. The access node controller transfers the handover value to the source access node. The source access node compares the signal parameters based on the handover value, and responsively hands-over the UE to the target access node which wirelessly exchanges user data with the UE.

Abstract: In a wireless communication network, a network control system receives a request for a media session with a wireless communication device. The control system responsively determines if the wireless device is idle and determines if a source base station serving the wireless device can support the media session. If the wireless device is idle and the source base station does not support the media session, then the control system identifies a target base station to support the media session. The control system transfers a first redirect message for delivery to the wireless device through the source base station and transfers a second redirect message for delivery to the target base station. The redirect messages have session information for the media session. The target base station receives an acceptance of the media session from the wireless device and exchanges media for the media session responsive to the acceptance.

Abstract: Media and systems for controlling roaming of a mobile device on a wireless-communications network are described. Wireless-communications systems along a coverage area border are designated as roaming border systems. A parameter value is communicated from wireless-communications systems of a home network to a mobile device. The parameter takes on a value indicating whether a mobile device is permitted to initiate a connection to a roaming network. A mobile device is restricted to use of home-network systems when a first parameter value is received. The mobile device is permitted to use home-network and roaming-network systems when a second parameter value is received. Thus, the mobile device can only roam when the second parameter value has been communicated thereto.
