Abstract: Disclosed in the present application is a method and a device of estimating a timing location. The method comprised: for each preamble subsequence, acquiring a detection window in which a peak value of a correlation value power of each preamble subsequence is located; accumulating the correlation value powers of the corresponding locations in the acquired detection window of each preamble subsequence, to obtain a cumulative sum of the correlation value powers corresponding to each location, wherein, in the accumulation, the correlation value powers of the preamble subsequence are within detection window in which peak values of respective correlation value powers are located; determining, according to the cumulative sum of the correlation value powers, peak power and noise power; and estimating, according to the peak power and the noise power, a timing location. The present application can solve the problem of a current M-stage preamble sequence solution.

Abstract: Disclosed are a method and device for determining an IP flow routing rule, wherein a technical solution of making an optimal routing rule through negotiation between a network device and a terminal is provided. The method comprises: when initiating an IFOM process, a first communication device generates a first routing rule that is different from a routing rule currently executed by a second communication device; the first communication device informs the second communication device of the first routing rule, and requests the second communication device to execute the first routing rule; and the first communication device determines, according to a message returned by the second communication device, the routing rule that is eventually executed by the second communication device.
