Title: WIRELESS TELECOMMUNICATIONS METHODS AND APPARATUS COMPRISING CHANGE OF DELIVERY MODE FOR SYSTEM INFORMATION
Abstract:
In a communications system wherein, when a particular system information block (SIB) changes membership, e.g., changes membership between a first set of system information (62-61) and a second set of system information (64-61), an access node (22-61) changes the delivery mode of the particular system information block (SIB). In an example implementation change of membership accordingly changes composition of broadcast messages (BM-61) which emanate from the access node. In some example embodiments and modes a system information modification indication is generated and transmitted to inform one or more wireless terminals of the change in membership. In some example embodiments and modes, for the particular system information block which changes membership between the first set and the second set, a post-change value tag for inclusion in the broadcast message second portion is derived from a pre-change value tag which was previously included in the broadcast message for the particular system information block.
