A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. Meanwhile, each of the Base Stations receives the MBS data to be transmitted and determines whether any of the MBS data has not been properly received. If so, the respective Base Station may initiate a process to recover the missing MBS data and/or to obtain information regarding the missing data to determine the duration of the time period that would have been required for transmitting the missing MBS. If the missing data has not been timely recovered, the respective Base Station determines a starting point and the duration of a silence period based on the information obtained, and refrains from transmitting signals along a communication channel allocated for transmission of MBS data, during that silence period.

Method and device for synchronization in wireless networks

A method and a system are provided for reducing collisions created between endpoints in a wireless local area network environment incorporated with a distributed antenna system (DAS), wherein the DAS comprises a plurality of station units (STUs) each adapted to communicate wirelessly with one or more wireless stations, and at least one access point unit (APU) connected to the plurality of STUs and adapted to communicate with a respective access point. The method comprises: at a first STU belonging to the plurality of STUs, receiving a first signal transmitted wirelessly; conveying the first signal towards the APU; and at the APU, adapting the conveyed signal to be transmitted to the access point associated with the APU, and in response to receiving the first signal, conveying a return signal towards at least two STUs belonging to the plurality of STUs.

Method and system for managing a wireless network comprising a distributed antenna system (DAS)

Apparatus and methods to permit the deployment of wireless base stations, where a deployed remote base station is backhauled to the core network over a wireless connection to an operatively attached donor base station using protocols that encapsulate backhaul communications within standard subscriber communication protocols.

Wireless communications network base station extension

A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. The method disclosed includes providing synchronization information to enable the plurality of Base Stations to start transmitting MBS data at a synchronized starting time point. Meanwhile, each of the Base Stations receives the MBS data to be transmitted and determines whether any of the MBS data has not been properly received. If so, the respective Base Station may initiate a process to recover the missing MBS data and/or to obtain information regarding the missing data to determine the duration of the time period that would have been required for transmitting the missing MBS. If the missing data has not been timely recovered, the respective Base Station determines a starting point and the duration of a silence period based on the information obtained, and refrains from transmitting signals along a communication channel allocated for transmission of MBS data, during that silence period.

The present invention discloses a method for carrying out a handover process in a wireless network, wherein the wireless network comprises at least a first and a second base stations belonging each to a different subnet associated of that wireless network and communicating through a first and a second gateways or foreign agents, respectively, and wherein the first base station is used as a serving base station currently in communication with at least one mobile subscriber station (MS). The method provided comprises a step of determining a traffic conveying entity as an intermediate anchoring point, and when the MS moves to a second subnet which comprises the second base station, a path is established for conveying traffic to/from that MS from/to a remote destination. The path comprises the intermediate anchoring point and the first gateway (or the first foreign agent).

Method for handover in wireless communications network comprising a number of sub-networks

A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. The method disclosed includes providing synchronization information to enable the plurality of Base Stations to start transmitting MBS data at a synchronized starting time point. Meanwhile, each of the Base Stations receives the MBS data to be transmitted and determines whether any of the MBS data has not been properly received. If so, the respective Base Station initiates a process to recover the missing MBS data or to obtain within a pre-determined time interval, information regarding the missing data to determine the duration of the time period that would have been required for transmitting the missing MBS. If the missing data has not been timely recovered, the respective Base Station determines a starting point and duration of a silence period based on the information obtained, and refrains from transmitting signals along a communication channel allocated for transmission of MBS data, during that silence period.
