A method comprising

• prioritizing, in cell reselection, a carrier frequency providing multimedia broadcast and multicast service;
• receiving a first system information block comprising at least a list and an information tag, said list comprising information related to broadcasted system information elements;
• observing a disappearance of an entry of a second system information block from said list, said second system information block comprising information related to multimedia broadcast and multicast services;
• observing a modification state of said information tag;
• and
• continuing said prioritizing, if said information tag is unmodified.

An apparatus comprising

• a control module configured to remove an entry of a first system information block from a list included in a second system information block to be broadcasted, said first system information block comprising information related to multimedia broadcast and multicast services, said list comprising information related to broadcasted system information elements;
• and
• a prohibition module configured to
• prohibit modification of an information tag included in said second system information block to be broadcasted, said information tag being indicative of a change of system information comprising at least said list, and to
• prohibit inclusion of a modification indicator in any paging messages that may be transmitted, said modification indicator being indicative of said change of said system information.

An apparatus comprising

• a connection controller configured to
• prioritize, in cell reselection, a carrier frequency providing multimedia broadcast and multicast service;
• and to
• receive a first system information block comprising at least a list and an information tag, said list comprising information related to broadcasted system information elements;
• and
• a control module configured to
• observe a disappearance of an entry of a second system information block from said list, said second system information block comprising information related to multimedia broadcast and multicast services;
• and to
• observe a modification state of said information tag;
• wherein
• said connection controller is further configured to continue said prioritizing, if said information tag is unmodified.
