There is described a multiple subscriber identity arrangement comprising a modem () and a control unit () 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 (S) by the modem, cause the modem to send (S) 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.

Measurement gaps triggering for a multi SIM mobile device

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.

Multi SIM management

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.
