Embodiment 1

[0054] An embodiment of the present invention provides a method for a terminal to automatically search and determine a neighboring cell in an LTE system. The method can automatically search for a neighboring cell on the terminal side, and determine the searched neighboring cell as a neighboring cell of the cell where the terminal is located. The method can The workload on the base station side is greatly reduced. The specific steps are as follows:

[0055] Step 1: For each of its receiving antennas, the terminal intercepts the data secondary synchronization sequence received by the receiving antenna on the downlink secondary synchronization channel, and uses the intercepted data as the antenna data of the receiving antenna. Sampling is performed, and the sampled data is used as the first time-domain data; the specific method of this step is as follows:

[0056] For each receiving antenna of the terminal, the terminal intercepts the data secondary synchronization sequence recei...

Embodiment 2

[0081] Embodiment 2 of the present invention provides a better method for a terminal to automatically search and determine neighboring cells in an LTE system. The method can automatically search for neighboring cells multiple times on the terminal side, and after multiple search operations, each time the The cell ID of the cell, that is, the cell corresponding to the ID value of the cell is determined as the neighboring cell of the cell where the terminal is located. This method can greatly reduce the workload on the base station side. The specific steps are as follows:

[0082] The terminal repeats steps 1 to 5 L times at different times, and after each process of steps 1 to 5, merges the cell identity corresponding to the position number of the time domain data that meets the preset conditions in the time domain correlation sequence, namely The cell ID value is added to the neighbor cell identification list, and the specific process is as follows:

[0083] When L=3, after th...

Abstract

The invention relates to the field of communication technology, and particularly relates to a terminal automatic search and neighbor adding method and a terminal, which are used for automatically searching and determining the neighbor on the terminal side. The method comprises the following steps that: the terminal intercepts and samples a data auxiliary synchronous sequence received by a receiving antenna on a downlink auxiliary synchronous channel as first time-domain data; the terminal converts the data auxiliary synchronous sequence stored thereby into a time-domain auxiliary synchronous sequence, samples the time-domain auxiliary synchronous sequence, and takes the sampled data as second time-domain data; the terminal performs normalization operation on the second time-domain data and the first time-domain data respectively to obtain time-domain related sequences; the terminal merges the time-domain related sequences by a merging method to obtain a merged time-domain related sequence; the terminal determines the cell identifier corresponding to the location sequence number of the data meeting the preset conditions in the merged time-domain related sequence; and the terminal determines the cell corresponding to the cell identifier as a neighbor. Thus, the method provided by the invention can automatically search and determine the neighbor on the terminal side.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for a terminal to automatically search and add neighboring cells and a terminal. Background technique [0002] With the continuous development of the third-generation mobile communication system (Third-generation mobile system, 3G), the long-term evolution (Long Term Evolution, LTE) project was proposed in the third-generation partnership project (The 3rd Generation Partnership Project, 3GPP) Due to the advantages of higher user data rate, improved system capacity and coverage, and reasonable and flexible spectrum resource allocation, LTE has developed rapidly. At present, many operators plan or are deploying LTE systems. [0003] In the LTE system, as the network becomes more complex, a large amount of wireless parameters and data will greatly increase the workload of network optimization personnel, and operators hope to reduce operating costs and manual interven...
