Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] figure 1 It is a schematic flowchart of a cell reselection processing method of a mobile terminal according to an embodiment of the present invention. Such as figure 1 , the method includes the following steps:

[0059] Step 101, when the mobile terminal is in the idle mode and the code domain power of the received signal of the main public control physical channel PCCPCH of the serving cell meets the cell reselection measurement criteria, the mobile terminal starts to perform reselection measurement and evaluation on the adjacent cells configured by the network, and the neighbor cells are measured and obtained. The signal power of the cell, and according to the measured signal power, determine the M cells in the neighboring cells that me...

Abstract

The present invention provides a cell reselection processing method for a mobile terminal and the mobile terminal. The method includes: performing reselection measurement and evaluation on adjacent cells configured by the network, and determining M cells among the adjacent cells that meet the reselection R criterion; Judging whether there is a cell satisfying the preset reselection condition among the M cells; if so, determining one of the cells satisfying the preset reselection condition as the reselection target cell, and triggering reselection; The serving cell of the mobile terminal does not trigger reselection; the preset reselection condition is: the cell and the current serving cell of the mobile terminal are in the same frequency relationship; or, when the cell and the current serving cell of the mobile terminal are in a different frequency relationship, the primary There is no unconfigured co-channel interfering cell with power comparable to this cell on the frequency point. The present invention can reduce the probability of reselection failure caused by measurement error under the condition that there is same-frequency interference in different-frequency adjacent cells and the network does not notify the terminal in a system message.

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...
