Method for realizing rapid cell selection for mobile station in wireless cellular network

Abstract

The invention relates to a method for realizing rapid cell selection for a mobile station in a wireless cellular network, comprising: carrying out prediction processing on location cell mobility to obtain a predicted cell priority ranking list, acquiring cell information from a cell information database according to the cell with the highest priority to carry out cell channel measurement and judgewhether the cell residence requirement is satisfied, residing in the cell or continuing taking out the cell which is never subjected to channel measurement from the predicted cell priority ranking list to carry out the above processing operations according to the results. The method is used and the resident historical cell list information is used to carry out mobility prediction by using a corresponding prediction algorithm, thus obviously shortening the wait time of cell selection, substantially improving the user experience, improving the communication service quality to a large extent, optimizing the network resources and workflow and featuring simple, convenient and rapid process, stable and reliable working performance and relatively wide applicable scope.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the technical field of cell selection of a mobile station in a mobile communication system, and specifically refers to a method for realizing rapid cell selection by a mobile station in a wireless cellular network. Background technique [0002] In a wireless cellular communication system, in order to communicate with the network, the mobile station must choose a suitable cell to camp, and then it can reliably receive and analyze system information, obtain relevant parameters to configure the uplink and downlink channels, and use the wireless resources of the cell to obtain network operation. The service provided by the provider, so cell selection is a necessary process for the mobile station. [0003] Cell selection is generally triggered by some events (such as power-on). After the mobile station receives a cell selection request, the radio resource control module will reque...

Problems solved by technology

For the stored information measurement method, the mobile station saves the cell information including the frequency point and scrambling code of the neighbor cell list of the cell before shutting down in the non-volatile storage area or the subscriber identity module card, so that when the mobile station wants to When performing cell selection, it is usually possible to give priority to measuring these cells. However, due to the randomness of the cell where the user is turned off, the neighbor cell list is not reliable, so this measurement method will often lead to failure, which in turn prompts the user to move. The station expands the range for initial measurement, in order to measure the wireless signal from the whole frequency band scanning process
