Abstract: A method may include detecting multiple system-information block (SIB) blocks and associated content. The associated content may be stored. The method may further include detecting multiple change flags associated with the multiple SIB blocks, each of the multiple change flags associated with one of the multiple SIB blocks. In response to detecting a change flag having a first change flag value, content of the SIB block associated with the first change flag may be reused. The first change flag value may represent an absence of a change to the content of the SIB block associated with the first change flag. In response to detecting the change flag having a second change flag value, the SIB block associated with the second change flag may be detected and the associated content stored. The second change flag value may represent a change to the content of the associated SIB blocks.
