Embodiment Construction
[0033] In the existing GSM network, network optimization personnel often pre-configure some cells that the terminal can cut into for the serving cell where the terminal is located, and use these cells as the original neighboring cells of the serving cell. Since the current original neighboring cells can only be configured with a maximum of 32, In this way, in traffic-intensive areas, due to the limitation of the number of cells in the original neighboring cells, it is often impossible to meet the needs of users, that is, when the terminal switches from the serving cell, there will still be poor power levels caused by untimely switching or failure to successfully switch to the original neighboring cells. , Poor call quality and dropped calls. In view of the above problems, the embodiment of the present invention provides a supplementary neighbor cell creation and handover scheme. By creating a supplementary neighbor cell (which may include cells that many terminals can switch in...

Embodiments of the present invention provide a method for creating a supplementary neighboring cell, a handover method, and a device. The method for creating a supplementary neighboring cell includes: when the serving cell where the terminal currently resides needs to supplement the creation of a neighboring cell, from the BSC or RNC to which the serving cell belongs In the controlled cells other than the original neighboring cells of the serving cell, or from the cells controlled by the BSC or RNC that does not belong to the serving cell, select the BCCH frequency point that is the same as the BCCH frequency point of any neighboring cell in the original neighboring cell Cell: When the terminal needs to switch from the current serving cell to the original neighboring cell, if it fails to successfully switch to the original neighboring cell, it can switch to the supplementary neighboring cell created above. The embodiments of the present invention can solve the existing problems of weak power level, poor communication quality and dropped calls caused by the inability to successfully cut into adjacent cells from the serving cell.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for creating a supplementary adjacent cell, a switching method and a device. Background technique [0002] At present, in the existing GSM network, each cell is configured with a traditional neighbor cell for a terminal to switch in through an air interface, usually in the form of a list. Specifically, for each serving cell, its traditional neighbors are pre-configured by network optimization personnel, and can only include 32 neighbors at most. When network optimization personnel configure traditional neighbors, in order to avoid mobile station measurement time If it is too long, the serving cell is configured with directly adjacent cells based on its geographical location with the serving cell. [0003] Since there are many broadcast control channel (Broadcast Control Channel, BCCH) frequency points in the GSM network, for example, there are 125 in the 90...
