A method, apparatus and a non-transitory computer readable medium include comparing two or more access points in a wireless communication network based upon one or more scenarios to minimize energy consumption, identifying one or more energy conservation constraints in the wireless communication network and controlling each of the two or more access points by selectively distributing traffic based upon the one or more energy conservation constraints.

Optimized energy consumption management in wireless base stations

Disclosed is a method for mobile station hard handoff from a source base station to a target base station of a Flex Duplex call in a CDMA wireless communication network that includes a step of establishing Flex Duplex capabilities of the mobile station. A next step includes sending the Flex Duplex capabilities of the mobile station to the target base station. A next step includes configuring the mobile station and the target base station for the handoff of the call using the Flex Duplex capabilities.

Mobile station handoff with flex duplex channel assignment in a wireless communication network

A system and method to provide cross-paging between circuit and packet data networks includes providing a mobile station being on a circuit-switched communication in a first area while maintaining a packet data session on the packet data network. When the mobile station moves to a second location area served by the circuit-switched network while the mobile station is still idle with respect to packet communications on the packet data network the location of the mobile station with respect to the circuit-switched network becomes unknown by the packet data network. In this case, the circuit-switched network informs the packet data network of a change in the mobile switching center serving the mobile station.

Cross-paging between communication networks

A communication system provides for an active handoff of a voice call between a packet switched network and a circuit switched network. An active handoff from the packet switched network to the circuit switched network is accomplished by multicasting the call over forward links of both networks during the handoff. An active handoff from the circuit switched network to the packet switched network is accomplished by multicasting the call over reverse links of both networks during the handoff. The former handoff further may be facilitated by routing the call for each network through a same packet data control switch, and the latter handoff further may be facilitated by routing the call for each network through a same mobile switching center. In order for a subscriber unit to operate concurrently in both networks, the subscriber unit may comprise multiple transceivers or a single transceiver that is rapidly switched between the networks.

Method and apparatus for inter-system active handoff of a hybrid subscriber unit

A system and method is disclosed to provide inter-packet-node paging between communication networks. The networks recognize whether inter-network paging is supported therebetween and advertise overlapping codes between networks having adjacent location areas. When the mobile station moves from the first network to the second network, the first network determines whether the second network shares an overlapping code therewith. If the networks share an overlapping code, the first network sends a paging request to the second network including link configuration information and the notification for the mobile station, wherein the notification can be delivered to mobile station in the second location area of the second communication network without the mobile station having to register in the second communication network.

Inter-packet-node paging between communication networks

A wireless communication system comprises an infrastructure that includes a first network element that is upstream of a second network element, wherein the first network element comprises a first transcoder and the second network element comprises a second transcoder. The communication system controls a transcoding of voice by determining a first bearer type supported by the first transcoder, determining a second bearer format type mutually supported by the infrastructure and a mobile station serviced by the infrastructure, and selecting one of the first transcoder and the second transcoder to transcode the voice based on the first bearer format type and the second bearer format type.

Method and apparatus for controlling distributed transcoders

A local multipoint distribution service base station apparatus for sending and receiving communication signals to and from subscribers includes a base unit having at least one rack which is adapted to receive at least one subrack. At least one communication signal generating unit is also arranged and configured to be received by the subrack. In addition, a transmitting/receiving unit is operationally connected to the base unit for transmitting and/or receiving the communication signals to and from the subscribers.

The invention provides methods and systems for power control in point-to-multipoint communications systems. Methods are described for both downstream and upstream control. Subscriber signals received at the base station,are level detected at receiver,and power adjust processing,and a control signal is sent to control output from the subscriber transmitter,. The invention maximizes the signal-to-noise ratio and signal-to-interference ratio for subscribers (CPE) while minimizing transmitted power. The invention is ideal for use in local multipoint distribution service (LMDS) systems.

Power control in point-to-multipoint systems

A wireless communication system (,) is disclosed in which a central office (,) generates a signal. A first base station (,) receives the central office signal and transmits a first broadcast signal in a first frequency range in response to the central office signal. A second base station (,) receives the first broadcast signal and transmits a second broadcast signal in a second frequency range in response to the first broadcast signal. A third base station (,) receives the second broadcast signal and transmits a third broadcast signal in the first frequency range in response to the second broadcast signal. In accordance with the present invention, a plurality of base stations are each able to provide one-way or two-way communication to a plurality of customers (,), with only one base station (,) receiving signals directly from the central office (,).

System and method for relaying signals to base stations in a wireless communications system

The invention provides methods and systems for power control in point-to-multipoint communications systems. Methods are described for downstream using an off-the-air monitor,and pick-up antenna,. The monitor detects the power level of the pick-up signal and a control signal sets the transmittal output from the base station in proportion to the detected composite power level.

Downstream power control in point-to-multipoint systems

Multipoint Stations are controlled by one or more pilot tones broadcasted by a base station. The pilot tones are used to control the local oscillators of the remote stations both for receive and for transmit. The pilot tone is also used to control the input gain and the transmit gain of the remote station.

The identity of the processor which is responsible for arbitrating bus access changes from time to time. Each processor has a plurality of possible arbitration states, which are controllable through execution of software by the processor.
