Abstract: The invention relates to a method for arranging handover in a wireless telecommunications system. Connection settings are stored in a terminal, wherein at least one network identifier is associated with alternative connection settings, the network identifier identifying a target network reachable by a connection from the terminal. The network identifier associated with the currently applied connection settings is compared with the network identifiers associated with the other available connection settings. The connection settings associated with the same network identifier as the one associated with the currently applied connection settings are then selected. The handover may then be carried out by using the selected connection settings.

Thereafter, selection is made of the network with which the mobile terminal shall communicate.

If the code does not designate the United State or Canada, then an ETSI domain is used, along with the appropriate transmission channels and power levels.

Abstract: A new and unique method or apparatus for power savings in a node, point, terminal or device in a wireless local area network (WLAN), or other suitable network, featuring one or more steps for delaying forwarding one or more data packets from a WLAN chipset to a host processor based on information received by the WLAN chipset about whether the host processor is in a sleep state. The host processor has a clock request pin to indicate when it is in the sleep state. The WLAN chipset has a pin that is connected to a sleep state signal of the host processor so that the WLAN chipset knows when it can wake up the host processor or not. The WLAN chipset has an internal threshold timer to fulfil latency requirements for delivering packets to the host processor.

Abstract: A new and unique method and apparatus to provide a mobile node, point, terminal or device with a technique to initiate a join operation with timing information received from a previous beacon and WLAN chipset's internal reference timestamp so that the WLAN chipset can synchronize itself with an access point network without needing to wait for a subsequent beacon as defined in the 802.11 standard specs. So, in other words, the essential aspect of the present invention is that the WLAN modem needs to get necessary timestamp (a time synchronization function (TSF)-correction)) information for performing the join-operation. The mobile node, point, terminal or device has its own TSF-counter and to join with the access point the TSF-counter needs to be synchronized with the access points TSF-counter. This update is performed in the WLAN modem using a communication that has been previously received from the access point (latest beacon, probe, etc.).
