    • Provided is a method and apparatus for synchronizing a time of day (TOD) in a convergent network, wherein the TOD is received from a time server connected in the convergent network and is provided to a terminal connected in a wired or wireless network, specifically a terminal connected in a heterogeneous network, that requires TOD information. The apparatus includes a time server that provides standard TOD information, a gateway or a host personal computer (PC) that provides the standard TOD information of the time server to the terminal in a 3rd layer or lower instead of an upper layer of the open system interconnection (OSI) 7 layer model, and the terminal that adjusts a local clock according to the provided standard TOD information. According to the method and apparatus, the terminal not only maintains a very precise TOD by obtaining TOD information of the time server periodically or when required, but also obtains the TOD information without using application software for processing the TOD information. Accordingly, power consumption of the terminal is decreased.
    • 提供了一种用于在收敛网络中同步时间(TOD)的方法和装置,其中,从连接在会聚网络中的时间服务器接收TOD并将其提供给连接在有线或无线网络中的终端,具体地, 终端连接在异构网络中,需要TOD信息。 该装置包括提供标准TOD信息的时间服务器,网关或主机个人计算机(PC),其提供时间服务器的标准TOD信息到第三层或更低层的终端,而不是开放系统的上层 互连(OSI)7层模型,以及根据提供的标准TOD信息调整本地时钟的终端。 根据该方法和装置,终端不仅通过周期性地或者需要时间地获取时间服务器的TOD信息,而且在不使用用于处理TOD信息的应用软件的情况下获取TOD信息,来维持非常精确的TOD。 因此,终端的功耗降低。
