Abstract

A frequency search method and apparatus are provided by the present invention. The method comprises receiving one of composite frames of a frequency point transmitted by a reference base station when a base station is performing frequency search on a frequency point in a frequency point set; according to received signal strength indication (RSSI) value in a predetermined time length of the frame, determining that the frequency point is a broadcast control channel (BCCH) carrier frequency point, then performing frequency correction channel (FCCH) detection and obtaining the frequency point information of the frequency point according to the detected FCCH; according to the RSSI value, determining that the frequency point is not a BCCH carrier frequency point, then determining that frequency search on the frequency point is failed, forbidding FCCH detection on the frequency point and waiting for receiving the composite frames of the next frequency point. The present invention reduces FCCH detection time and improves the performance of a base station.

The frequency search algorithm is a self-frequency algorithm. The main steps of the search algorithm are the following steps: Step 2: Configure the hand-pick mode to search. 2. The average value is less than SS. If CC is CC, the offset is calculated. The SS receiving strength indicator steps 3, SC and CC. The same occurrence in the CC appears in our CC to the CC's large SC and CC appears to be in the middle of the smaller SC And the solution of CC. From the point of view of the search, the first is CC search for SC and CC with only CC abilities. In the CC test and multiple measurements, only the CC to CC is the big and small. The average value can't be as big as the -95 - in the park. Can cause the same. The C 所示 shown in 55 has the most force of CC 5 due to the fact that only the first SS mean is less than SS at least

The main purpose of this book is to search for the performance of the existing CC in the centralized search in the CC before the CC. The solution is to address the above. This aspect of the introduction of the frequency search method. The frequency search method of the present invention is based on the intermediate frequency search in the packet base set, and at least the predetermined length before the CC is the CC frequency. The CC is the CC.

Whether the SS of the medium or multiple of the media in the middle of the CC scheme is the CC frequency is the CC, and solves whether the existing search in the wood is CC or not. The same performance of the CC reduces the performance of the CC with improved performance. The explanation of the part of the cost of the unexplained step of understanding the explanation of the cost is obvious. The common control 2 of the existing wood S system CC is the non-CC SS yield of the existing wood. 3 is the flow of the frequency search method. The flow is 4 is the CC frequency flow 5 is the frequency search. The flow 6 of the method is a schematic diagram of the frequency search device of the present invention. The schematic 8 of the CC 63 is an illustration of the CC channel 64 of the present. The method of the present invention is a re-CC. If the SS of the S-integrated search is received before the CC or if the SS of the multi-predetermined SS is CC, the frequency is CC. In the case of no, the special ones in this book are each other. The following explanations of the following descriptions of the Ming and Qing dynasty are not used for the final version.

In the case of a predetermined long SS pass, the SS maximum value before updating or the SS minimum pre-predetermined long SS is greater than the SS maximum value of the previous mercury. The result is that the previous SS maximum value is updated before the force is predetermined. Otherwise, the former SS maximum value of the former mercury remains unsupported. The SS before the predetermined length is smaller than the former SS of the former mercury. The minimum value is the SS before the minimum SS is updated. The SS of the former mercury is kept at the minimum. Step 5404, whether the result is a CC or the result of the previous multiple test described in step S406. Step S406, whether the predetermined result of the presence of the SS value is the step S404 of the SS maximum value of the SS SS before the predetermined SS SS update or the SS minimum value of the SS minimum value of the SS minimum value Said is CC frequency. In step S404, as long as the predetermined SS is updated, the SS maximum value in the pre-initial or the SS in the pre-instance is the smallest, and the SS maximum value in the pre-introduction is smaller than the minimum value, that is, the non-CC frequency is the CC frequency in the rest.
