Cell reselection processing method for mobile terminal and mobile terminal

Abstract

The invention provides a cell reselection processing method for a mobile terminal and the mobile terminal. The method comprises the following steps: performing reselection measurement and assessment on neighbor cells allocated by a network, and determining M cells meeting a reselection R rule in the neighbor cells; judging whether cells meeting a preset reselection condition exist in the M cells or not; if so, determining one of the cells meeting the preset reselection condition as a reselection target cell, and triggering reselection; otherwise, staying in the current service cell of the mobile terminal, and not triggering the reselection, wherein the preset reselection condition is that: the cell and the current service cell of the mobile terminal have a same frequency relation; or when the cell and the current service cell of the mobile terminal have a different frequency relation, same frequency interference cells which are not allocated and of which the power can be compared with the cell do not exist on a main frequency point of the cell. The method can reduce reselection failure probability caused by measuring errors in the conditions that different-frequency neighbor cells have the same frequency interference and the network does not inform the terminal of the situation in system messages.

Description

technical field [0001] The present invention relates to the field of wireless communication systems, in particular to a cell reselection processing method of a mobile terminal under the network environment of the third generation mobile communication system TD-SCDMA and the mobile terminal. Background technique [0002] The terminal starts up or reselects to a certain cell, and obtains parameters related to reselection by reading the system information of the serving cell, including Q rxlevmeas , S intersearch Wait. In the TD-SCDMA system, the RSCP of the received signal code domain power of the broadcast channel is generally used to determine the reselection decision basis. For a mobile terminal in an idle state, if the signal power of the current serving cell satisfies the evaluation criterion for inter-frequency reselection measurement, the radio resource control layer RRC will trigger the measurement scheduling of the signal power of inter-frequency adjacent cells, and...
