摘要:
A method for synchronizing measurements in a mobile communication apparatus having a first active radio access means (100) adapted to communicate according to a first radio access technology (RAT) and at least a second passive radio access means (200) adapted to communicate according to a second RAT. A time reference common to the first and the second access means (100) is generated. At least one time schedule is obtained, said schedule indicating at least one time gap wherein the second access means (200) is allowed to be active. The activation time of the schedule is based on the common time reference. An arrangement adapted to generate the common time reference and the time schedule is also disclosed.
摘要:
A method and apparatus for measurement event synchronization of a portable radio communication apparatus providing multiple radio access technologies, wherein an idle gap is identified between transceiver activities of a first radio access technology device, and an execute signal is sent to a second radio access technology device for initiating inter radio access technology measurements of the second radio access technology device, to be performed during the gap.

摘要:
A user equipment (UE) in a communication system measures the power received in a bandwidth on possible downlink carriers in a frequency band that is supported by the UE in order to search for available carriers. Search times can be decreased on average by using a specially configured filter to process the received power measurements and then determining likely carriers based on the filtered values. Metrics from the filter can be used to indicate both where to perform cell search and where not to perform cell search.

摘要:
By evaluating a cell selection criterion S during scans for available public land mobile networks (PLMNs), a user equipment (UE) can avoid network service interruptions by not selecting PLMNs for which there exist no suitable cells. The cell selection criterion can be evaluated based on cell parameters either read during the PLMN selection procedure or locally stored before the PLMN selection procedure. It is possible to reduce the time required for PLMN scans and UE power consumption.

摘要:
By adapting its search procedures, a user equipment in a mobile communication system can shorten the time needed to find a cell or public land mobile network. If a first cell in a first radio access technology has been found, the equipment can exclude one or more frequencies from a search for cells in a second radio access technology. Thus, time and power are not wasted searching for cells in the second radio access technology that cannot be found.
