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

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 kind of conflict will occur It will continue to exist. In this case, because the priority of monitoring PICH is higher than that of monitoring BCH, the mobile communication terminal cannot always monitor 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.
