In a mobile communication device having multiple subscriber identification modules (SIMs), the processing of cell broadcast service (CBS) messages is optimized. It is determined, whether both a first SIM (SIM1) and a second SIM (SIM2) camp on the same PLMN. If this is the case, then a combined CBS message list comprising message IDs of CBS messages to be received is generated. This combined CBS message list includes message IDs from the individual CBS message lists of SIM1 and SIM2. Then it is determined, whether SIM1 and SIM2 moreover camp on the same cell. If this is the case, then it is sufficient when only one of SIM1 and SIM2 monitors and processes CBS messages from the combined CBS message list and a selected one of SIM1 and SIM2 is correspondingly instructed. If however, SIM1 and SIM2 camp on the same PLMN but on different cells, then the geographic scope indication of a received CBS message is analyzed and only if the geographic scope indicates "PLMN-wide", then the same handling as described above is carried out. |
