Problems solved by technology
[0009] It is conceivable that in the current existing technology, because the wireless environment is affected by various uncertain factors such as weather and terrain, the measurement level of the BCCH carrier frequency must change very frequently, and this will cause the mobile device to be sensitive to such targets. Monitoring actions such as BSIC synchronization, BCCH channel decoding and other operations frequently occur, which will also lead to frequent cell reselection, thus resulting in unstable operation of the mobile device, great waste of resources on the mobile device, and poor allocation of network signaling resources. Reasonable and other unfavorable circumstances

Embodiment Construction
[0067] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.
[0068] see Figure 1 to Figure 5 As shown, the method for maintaining the reselected target cell in the wireless communication system, wherein the method includes the following steps:
[0069] (1) The mobile device selects a cell that meets the camping conditions as the current serving cell, and decodes the system message of the broadcast control channel of the current serving cell to generate a list of adjacent cell frequencies;
[0070] (2) The mobile device measures the level of the adjacent cell frequency point list and sorts the measurement results, and generates and maintains the reselection target cell list, including the following steps:
[0071] (a) The mobile device selects the frequency point with the highest level value as the quasi-target frequency point from the measurement results of the adjacent cell frequency point list, and...

The invention relates to a method for maintaining a reselected target cell in a wireless communication system, comprising the following steps of: selecting a current service cell and decoding system messages to generate an adjacent cell frequency point list, performing level measurement on the adjacent cell frequency point list and sequencing to generate and maintain a reselected target cell list, synchronously reselecting frequency points in the target cell list, updating the frequency point system information in the reselected target cell list, and selecting the optimum cell from the reselected target cell list as the new service cell during cell reselection. The method for maintaining the reselected target cell in the wireless communication system avoids the problems of instability of operation, large power consumption and the like of mobile equipment, reduces fluctuation of the reselected target list, reduces the occurrence of cell reselection and the power consumption of the mobile equipment, improves the quality and efficiency of wireless communication service, has stable and reliable operating performance and wider range of application, and lays a solid foundation for providing better implementation methods for the perfection and development of the modern mobile communication technology.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to the technical field of maintaining frequency point lists of mobile equipment adjacent cells in a wireless communication system, and specifically refers to a method for maintaining a reselected target cell in a wireless communication system. Background technique [0002] GSM (Global System for Mobile communications, Global System for Mobile Communications) is the most widely used digital mobile communication system in the world. [0003] In the current GSM wireless communication system, in multiple processes such as cell selection and cell reselection, it is necessary to use the content of the adjacent cell frequency point list for judgment, such as whether to perform fast cell selection through the adjacent cell frequency point list after power-on, Whether the target neighboring cell is suitable for reselection, etc. It can be said that the frequency point list of ne...
