Communication terminal and method for using a communication service

摘要

A communication terminal is described including a transceiver, a plurality of subscriber identity modules, wherein the transceiver is configured to receive a signal for each of the subscriber identity modules, a determiner configured to determine, for each subscriber identity module, a rating of the received signal and a controller configured to select a subscriber identity module from the plurality of subscriber identity modules for a communication service based on the ratings and configured to control the transceiver to use the communication service by means of the selected subscriber identity module.

1. A communication terminal comprising:
a transceiver; a plurality of subscriber identity modules, wherein the transceiver is configured to receive a signal for each of the subscriber identity modules; a determiner configured to determine, for each subscriber identity module, a rating of the received signal; and a controller configured to select a subscriber identity module from the plurality of subscriber identity modules for a communication service based on the ratings and configured to control the transceiver to use the communication service by means of the selected subscriber identity module, wherein the controller determines whether more than one subscriber identity modules are in a maximum signal strength set and, if this is the case, selects the subscriber identity module with a maximum signal quality determined based on paging decoding errors out of the maximum signal strength set, and, if there is only one subscriber identity module in the maximum signal strength set, selects the subscriber identity module with the maximum signal quality determined based on the paging decoding errors; wherein each subscriber identity module of the plurality of subscriber identity modules is associated with a cellular mobile communication network; wherein the subscriber identity module identifies the communication terminal as a subscriber terminal of the cellular mobile communication network associated with the subscriber identity module; wherein the subscriber identity modules are at least partially associated with the same cellular mobile communication network; and wherein the determiner is further configured to determine whether the subscriber identity modules are camped on different serving cells of the same cellular network and to determine the rating of the received signal if the subscriber identity modules are camped on different serving cells of the same cellular network.
