摘要:
A method for carrying out a handover of servicing a mobile terminal from a currently serving base station to another base station in a cellular network, comprising the following steps. The currently serving base transmits information associated with the mobile terminal to one or more of its neighboring base stations. The neighboring station(s) respond by providing the serving base station with information related to the quality at which they are able to receive communications from the mobile terminal. Based on the responses received from the neighboring base stations, the serving base station selects which of its neighboring base stations will be the target base station for the mobile terminal. Upon selecting the target base station, a handover procedure is carried out, following which, the mobile terminal will receive and transmit communications via that target base station.

In a wireless network which comprises a first plurality of base stations and a second plurality of access network gateways, there is provided a method for tracking and/or paging a mobile terminal, wherein the method comprises the steps of: providing a mobile terminal located within the wireless network, and wherein the mobile terminal is in an active mode; selecting a first access network gateway out of the second plurality of access network gateways to be an anchor gateway for location and/or paging control for the mobile terminal; and upon receiving at the first access network gateway a request for a location update of the mobile terminal which has meanwhile entered an idle mode, selecting a base station for communicating with the mobile terminal from among the first plurality of base stations, and providing the selected base station with information required for verifying the identity of the mobile terminal and/or for retaining the security integrity of the selected base station while carrying out location update of the mobile terminal. Preferably, the paging Controller ID (or its location) is used for the update of the traffic anchored GW, and can then be used for allocating the paging controller by the traffic anchored GW during the paging procedure.

A method for re-connecting a mobile terminal roaming in a wireless network via a target base station (TBS) after the occurrence of an uncontrolled disconnection of the mobile from a serving base station (SBS) via which the mobile was receiving and transmitting communications prior to the uncontrolled disconnection. An entity is established associated with the wireless network operative as a single authentication access entity (SAE) for the mobile, as long as its location remains within that wireless network, the identity of which is sent to the SBS. Following the occurrence of uncontrolled disconnection and in response to the mobile sending an indication to the TBS, the TBS is requested to execute the entry of the mobile as a handover process. The SBS transmits the identity of the SAE to the TBS. At the TBS, parameters associated with the mobile are retrieved from the SAE.
摘要:
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 Internet Protocol (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.
摘要:
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 Internet Protocol (IP) datagram is selected 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 selection and prior to establishing a connection between the mobile subscriber terminal and the second base station, IP datagrams that will be received at that network gateway after that first IP datagram had been received and which are addressed to the MSS, are backed up. Upon establishing a connection between the MSS and the second base station, 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.

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.
摘要:
A method for authenticating a mobile terminal in a wireless network is disclosed. The method includes transmitting a request for authenticating the mobile terminal in that wireless network operative to provide services at a location where the mobile terminal is currently present, receiving the request at a base station associated with that wireless network, and determining an entity associated with the wireless network to be operative as a single authentication access entity for that mobile terminal, as long as the mobile terminal location remains within that wireless network and traffic is directed through any location associated with that wireless network.
