Abstract: A system and method for finding a wireless local area network, WLAN, when a mobile terminal is connected to a cellular network. A position associated with each WLAN operating within the coverage area of the cellular network is stored in a database. At predefined intervals or conditions, the system determines a current position of the mobile terminal, and determines whether the current position of the mobile terminal is close enough to a stored WLAN position for the mobile terminal to connect to the WLAN corresponding to the stored WLAN position. If so, a notification is sent to the mobile terminal indicating that the mobile terminal is within range of the identified WLAN. The mobile terminal then scans for the identified WLAN.

Abstract: A signal-power related quantity is estimated by repeating a processing step, where measured values of instantaneous signal powers are processed. At each relevant part step of the processing and for each relevant matrix (99), elements (98) that are indicated to be negligibly small are changed to instead be exactly equal to zero. The computational complexity can thereby be decreased considerably. The principles are applied on determination of signal-power related quantities in wireless communications systems.

Abstract: Methods and apparatus for determining when uplink synchronization has been achieved when entering or adding a link in soft handover to a new node in a communication system. Transmit power control (TPC) commands from the new link are not included in a TPC command combination until an uplink synchronization detector determines that synchronization has been achieved. Since in many communication systems, a pattern of TPC commands is transmitted on the new downlink as long as the new node's uplink is not synchronized, the uplink synchronization detector can determine whether synchronization has been achieved by determining whether the TPC command pattern is present in the new downlink. In this way, the UL synchronization detector reduces the occurrence and magnitude of unwanted peaks and dips in uplink transmitted power.
