    Abstract: PURPOSE: A method and apparatus for updating a terminal software in a network system are provided to rapidly update a terminal software between a communication server and plural terminals. CONSTITUTION: A message generating unit(710) generates at least one of a message for indicating the last portion of an image, a software activation request message and a software update termination message. The software activation request message is for applying an image of the terminal software transferred from the plural terminals. The software update termination message includes the update termination for the plural terminal, and a transfer window size determination unit(730) determines the size of the transmission window transferred from the plural terminals.

    Abstract: An OLT(Optical Line Terminal) system in a PON(Passive Optical Network) for CBMS(Convergence of Broadcasting and Mobile Service) is provided to avoid a distortion of broadcast signals, due to a transmission delay and a loss of broadcast packets, by limiting the bandwidth of communication signals in order to guarantee the transmission bandwidth of broadcast signals. An OLT system in a PON for CBMS comprises a band monitoring part(601), a band limiting part(603), a multiplexing part(605), a switch(607), MAC processing parts(609-1-609-n), and optical transceivers(611-1-611-n). The band monitoring part(601) monitors the data packet band of a broadcast signal delivered from a core network or a metro network. The band limiting part(603) limits the band of a communication signal delivered from the core network or the metro network. The multiplexing part(605) multiplexes the monitored broadcast signal and the band-limited communication signal. The switch(607) switches the multiplexed signal packets to switch ports corresponding to PON links. The MAC processing parts(609-1-609-n) process the multiplexed signal packets, switched and transmitted through the switch(607), using an OLT MAC function. The optical transceivers convert the multiplexed signal packets, processed by the MAC processing parts, into optical signals and transmit them to associated PON links.
