In a wireless communication system, a client terminal may be required to periodically receive the broadcast and multicast system information of the serving and neighbor base stations. In most scenarios the broadcast and multicast system information of base stations may not change frequently. A method and apparatus are disclosed to store, manage and use the broadcast and multicast system information of a set of latest serving and neighbor base stations. This may enable a client terminal to avoid receiving and processing all or most of the base station system information messages. This may significantly reduce the active states of a client terminal and may lead to significant reduction in power consumption, which may be a critical advantage for battery operated client terminals. The present invention may also reduce the time taken by a client terminal to get connected or reconnected to a base station, which may improve the user experience.
