Mobile communication terminal and dispatching method thereof

Abstract

The invention provides a mobile communication terminal and a dispatching method thereof. The method comprises the following steps: under the condition of being synchronous with a target cell, the mobile communication terminal judges whether a first task and a second task under idle mode conflict in time; the first task is reading page messages of a serving cell from PICH of the serving cell next time and the second task is reading system messages of the target cell from BCH of the target cell next time; when the first task and the second task conflict in time, the mobile communication terminal gives up the first task, keeps synchronization with the target cell till the second task is completed and returns to the serving cell after the second task is completed; otherwise, the mobile communication terminal respectively completes the first task and the second task. The invention can lead the mobile communication terminal to complete the tasks of the target cell smoothly while guaranteeing that the services of the serving cell are not influenced when the task of the serving cell and the task of the target cell conflict.

Description

Technical field [0001] The invention relates to the field of wireless communication technology, in particular to a mobile communication terminal and a scheduling method thereof. Background technique [0002] In the wireless communication system, the mobile mobile communication terminal is in idle mode when there is no business, and the main tasks of the mobile communication terminal in the idle mode include the following two parts: [0003] Serving cell task, monitor the paging indicator channel (PICH, Paging Indicator CHannel) to receive paging information from the network and perform measurement; and [0004] Target cell (also called neighboring cell) task, monitor BCH (Broadcast Channel, broadcast channel), obtain system information, reside in a better cell through cell reselection, and perform acquisition of PLMN (Public Land Mobile Network, public Land mobile network) information process, etc. [0005] According to the 3GPP protocol, system information and paging information...

Problems solved by technology

[0009] In this case, since both PICH and BCH are sent periodically, when the sending cycle of BCH is a positive integer multiple of the sending cycle of PICH, this conflict will continue to exist. In this case, due to the priority of monitoring PICH The priority is higher than the priority of monitoring the BCH, so the mobile communication terminal cannot always monitor the BCH, and cannot read the required SIB, and cannot complete the task of the target cell;

[0010] In order to solve the above problems, in the prior art, either the task of the target cell or the task of the serving cell is given up, but giving up the task of the target cell will result in the inability to reselect the cell, Giving up the task of serving the cell will cause the mobile communication terminal to be unable to initiate services for a period of time (the time for cell reselection and obtaining PLMN information), and will also miss incoming calls.
