20080279150 | METHOD FOR HANDOVER IN WIRELESS COMMUNICATIONS NETWORK COMPRISING A NUMBER OF SUB-NETWORKS - 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). | 11-13-2008 |
20090034459 | METHOD AND DEVICE FOR SYNCHRONIZATION IN WIRELESS 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 comprises providing synchronization information to enable all of said 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 in order to determine the duration of the time period that would have been required for the transmission of 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 any signals along a communication channel allocated for transmission of MBS data, during that silence period. | 02-05-2009 |
20090213810 | TRANSFER OF COMMUNICATION SESSIONS BETWEEN BASE STATIONS IN WIRELESS NETWORKS - A method and devices are provided to enable continuing a communication session currently carried by a mobile subscriber station (MSS) while switching from a first base station to a second base station. During the communication session that is being held with the MSS, a first IP datagram is determined from among a plurality of IP datagrams associated with that communication session and received at a network gateway adapted to convey IP traffic received from the MSS. Following that determination, IP datagrams that will be received at that network gateway after that first IP datagram and which are addressed to the MSS are backed up. Upon establishing a connection between the MSS and the second base station, the first base station ceases to convey uplink traffic originated by the MSS, the IP datagrams that were backed up are forwarded to the MSS, and all further IP datagrams which are addressed to the MSS and received at that network gateway after establishing the connection between the MSS and the second base station, will be forwarded to the MSS through the second base station. | 08-27-2009 |

20110138448 | METHOD AND APPARATUS FOR ENABLING MOBILITY IN MOBILE IP BASED WIRELESS COMMUNICATION SYSTEMS - A method is provided for providing secured mobile IP services to a mobile terminal which is currently associated with an access network different from its own home access network. The method is characterized by creating a virtual mobile node at an access network server of the current access network, which communicates with a Home Agent associated with the terminal's home mobile network and with one or more access points associated with the current access network, at which the mobile terminal is currently located. | 06-09-2011 |
20120257599 | TRANSFER OF COMMUNICATION SESSIONS BETWEEN BASE STATIONS IN WIRELESS NETWORKS - A method for carrying out a handover procedure, following which a mobile terminal (MS) currently in communication with a first base station (BS), will communicate via a second BS. The method includes upon initiating a handover procedure, determining that the MS will receive all future IP packets via the second base station, following this determination and prior to establishing a connection between the MS and the second BS, forwarding all IP packets being addressed to the MS to the second BS, and buffering the received IP packets thereat, and upon establishing a connection between the MS and the second BS, forwarding the IP packets that were buffered at the second BS to the MS, wherein the buffered IP packets are delivered to the MS before delivering any packets addressed thereto along a new path extending to the second BS which does not include the first BS. | 10-11-2012 |
