摘要： To perform handoff of a mobile station from a source wireless network controller of one wireless access technology to a target wireless network controller of a different wireless access technology, a first message for initiating a handoff is sent from the source wireless network controller to the target wireless network controller. The source wireless network controller receives, from the target wireless network controller, a second message responsive to the first message, where the second message contains information to enable identification of cell segments neighboring the target wireless network controller for which signal strength measurements are to be performed. In response to the second message, signal strength measurements made by the mobile station are received by the target wireless network controller.

摘要： A system and method of facilitating handoff of communications with a mobile terminal between a first wireless access network and a second wireless access network having different air interfaces. The system and method including pre-registering the mobile terminal in the second access network prior to handoff, while the mobile terminal is conducting a communication session using the first access network. Upon a determination that a handoff is needed, communication is transparently tunneled to the secondary access network through the primary access network. During tunneling, the air link of the first wireless access network is employed to communicate with the secondary access network to facilitate the handoff.

摘要： 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.

摘要： 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.

摘要： A method and apparatus for controlling forward gain transmission values of a base station transceiver system includes adjusting forward gain values according to mobile station power control commands as well as to forward gain values commanded by a base station controller. The forward gain values commanded by a base station controller are used as an input to determining what the forward gain value should be and are not implemented exactly as commanded. Thus, a base station transceiver system formed according to the present invention examines the power control commands received by a mobile station relative to a power gain command received by the base station controller. For example, if the power gain command received from the base station controller is responsive to a forward gain value that was transmitted in the past, when a plurality of power control commands were received in the interim, the plurality of power control commands are accounted for as well as the forward gain value commanded by the base station controller when determining the actual forward gain value for the next transmission. Additionally, subsequent power gain commands are also compared to prior power gain commands wherein subsequent adjustments are only made based on the differences between them.

摘要： Methods and apparatuses are provided for CDMA (code division multiple access) access availability to a large cell area, and for traffic channel establishment. A group of cell site modems are configured to look for access attempts generated in respective complete and/or sectorized circular or annular shaped areas centered at the center of the cell area, the areas collectively covering the cell area. To achieve this, each cell site modem has a local clock and the local clock within the first of the cell site modems is synchronized with a standard network time, and the local clock of each of the subsequent cell site modems is offset by a respective delay with respect to the standard network time which causes the cell site modem to search within its respective annular shaped area. A cell site modem is also made available as a traffic cell site modem and is operable to have its traffic acquisition search window centered at a location of an access attempt. Alternatively, a plurality of traffic cell site modems may be provided, each having dedicated circular or annular coverage areas within the cell. The traffic cell site modems also preferably have a local clock which may be synchronized, either to a standard network time, or to a respective delay which causes it to search in its respective area. Methods and for handing off between circular and annular shaped traffic coverage areas are also provided.
