Abstract: There is described a multiple subscriber identity arrangement comprising a modem (10) and a control unit (13) associated with said modem. The modem is capable of receiving and/or transmitting messages related to either one of at least first and second subscriber identities, but not simultaneously. The control unit is configured to, when communication activity associated with the first subscriber identity is being performed (S1) by the modem, cause the modem to send (S3) an indication to a network associated with the first subscriber identity requesting compressed mode. The control unit is further configured to monitor the signalling associated with the second subscriber identity during a compressed mode gap associated with the first subscriber identity.

Abstract: There is described a multiple subscriber identity arrangement having a modem capable of receiving messages related to either one of at least two subscriber identities, but not simultaneously. The arrangement further comprises a control unit configured to, when the modem performs communication activity associated with a first subscriber identity: determine whether gaps not allocated for the communication activity associated with the first subscriber identity coincide with paging occasions associated with a second subscriber identity; and, if at least one gap not allocated for the communication activity associated with the first subscriber identity coincides with at least one paging occasion associated with the second subscriber identity, cause the modem to switch to the second subscriber identity to read one paging message on a paging channel associated with the second subscriber identity.

Abstract: The present invention relates to a method of performing inter System radio measurements in compressed mode. A communication device, camped on a first radio communication network, performing the method determines whether a given measurement gap coincides in time domain with a measurement position defined by the communication device. In case the measurement position coincides with the position of the measurement gap, then the communication device performs consequently during the measurement gap a first type of measurement with respect to the first communication network and a second type of measurement with respect to a second communication network.

Abstract: There is described the controlling of a multiple subscriber identity arrangement comprising a modem (10), and a control unit (13) associated with the modem. The modem is capable of receiving messages related to at least two subscriber identities, but not simultaneously, and comprises a listening block (11) capable of monitoring at least one signalling channel associated with the second subscriber identity. The control unit (13) is configured to interrupt ongoing communication activity on the first subscriber identity during at least one signalling occasion (41,42,51,52) associated with the second subscriber identity and cause the listening block of the modem to monitor the signalling channel associated to the second subscriber identity during said occasion.

Abstract: Multi SIM modem adapted to receive messages related to at least two subscriber identities, wherein it comprises: a reference clock module configured to define a reference clock for the multi SIM modem, a first protocol stack block configured to measure a first frequency error between the multi SIM modem and a cell related to a first subscriber identity, a second protocol stack block configured to measure a second frequency error between the multi SIM modem and a cell related to a second subscriber identity, and a reference clock management block configured to control an adjustment of the reference clock in the reference clock module, based on information from the first and second protocol stack blocks.

Abstract: The present invention generally relates to devices and methods, in a cellular network, for measuring a power level for each one of a plurality of BCCH carriers emitted by neighbouring cells around a Mobile Set, in: dividing the plurality of carriers into at least a first group and a second group; handling measurements of the power level of each carrier included in the first group, so as the time lapsed between two consecutive measurements for each carrier is lesser than a first threshold; handling measurements of the power level of each carrier included in the second group, so as the time lapsed between two consecutive measurements for each carrier is lesser than a second threshold different from the first threshold.

Abstract: A method and apparatus for deciding whether the handover has to be done or not, where the decision is taken by the mobile unit. The mobile unit can reject the command from the base station if the quality of the communication might not be maintained in the second network. This decision is taken measuring some quality parameters of the second network and comparing them with a predefined threshold.
