Abstract: An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Abstract: A wireless communications network includes a first base station system that performs wireless communications according to a first protocol (e.g., 1xEV-DO protocol) and a second base station system that performs wireless communications according to a second, different protocol (e.g., IS-2000). A link is provided between the first and second base station systems to enable a network-initiated handoff procedure. If a source base station system detects that a handoff of a mobile station to a target base station system is required, the source base station system exchanges messaging over the link with the target base station system to perform the handoff. In one example, the handoff is a hard handoff.

Abstract: A wireless communication network generally includes a number of subscriber units, a base station controller, and a base station transceiver coupled to the base station controller. A parameter specifying an interval at which subscriber units in the wireless communication network are permitted to generate autonomous messages is stored, for example, in a system parameter database at the base station. The parameter is broadcast by the base station transceiver over-the-air to subscriber units in the wireless communication network. In response to receipt of the parameter, the subscriber units store the parameter and thereafter transmit autonomous message over-the-air only in accordance with the parameter. In one preferred embodiment, the parameter regulates how often autonomous messages can be transmitted by individual subscriber units. Alternatively or additionally, the parameter can be used to ensure that the subscriber unit is in a stable state before an autonomous message is transmitted by preventing transmission of autonomous messages while the subscriber unit is generating messages at too rapid of a rate.
