SYSTEM INFORMATION BROADCAST IN MACHINE-TO-MACHINE RADIO ACCESS SYSTEMS

摘要

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.

1. A method comprising:
detecting, from a downlink channel in a wireless communication network, a plurality of system-information block (SIB) blocks and content associated with each of the plurality of SIB blocks; storing the content associated with each of the plurality of SIB blocks; detecting, from the downlink channel in the wireless communication network, a transmission including a plurality of change flags associated with the plurality of SIB blocks, each of the plurality of change flags associated with one of the plurality of SIB blocks; in response to detecting a change flag of the plurality of change flags having a first change flag value, reusing the content of the SIB block associated with the change flag, the first change flag value representing an absence of a change to the content of the SIB block associated with the change flag; in response to detecting the change flag having a second change flag value, detecting the SIB block associated with the change flag and storing the content of the SIB block associated with the change flag, the second change flag value representing a change to the content of the SIB block associated with the change flag; and selectively detecting SIB blocks having changed content based on the change flag values of the plurality of change flags.
