A network selection method applied to a mobile terminal, wherein a first card slot and a second card slot are disposed in the mobile terminal, and when the first card slot accommodates a first identification card and the second card slot accommodates a second identification card, the network selection method applied to the mobile terminal comprises: executing, by the mobile terminal, a communication service by using the first identification card; determining that the communication service of the first identification card interferes with the second identification card; and adjusting cell reselection information of the second identification card, so that the second identification card reselects to a non-interfered-with cell, wherein the adjusting cell reselection information of the second identification card, so that the second identification card reselects to a non-interfered-with cell comprises: decreasing a cell priority of a serving cell of the second identification card, and/or increasing a cell priority of the non-interfered-with cell of the second identification card, so that the cell priority of the non-interfered-with cell of the second identification card is higher than the cell priority of the serving cell of the second identification card; and/or decreasing a cell measurement value of the serving cell of the second identification card, and/or increasing a cell measurement value of the non-interfered-with cell of the second identification card, so that the cell measurement value of the non-interfered-with cell of the second identification card is greater than the cell measurement value of the serving cell of the second identification card; and/or increasing a reselection threshold of the serving cell of the second identification card, so that the second identification card cannot access the serving cell. executing, by the mobile terminal, a communication service by using the first identification card; determining that the communication service of the first identification card interferes with the second identification card; and adjusting cell reselection information of the second identification card, so that the second identification card reselects to a non-interfered-with cell, wherein the adjusting cell reselection information of the second identification card, so that the second identification card reselects to a non-interfered-with cell comprises: decreasing a cell priority of a serving cell of the second identification card, and/or increasing a cell priority of the non-interfered-with cell of the second identification card, so that the cell priority of the non-interfered-with cell of the second identification card is higher than the cell priority of the serving cell of the second identification card; and/or decreasing a cell measurement value of the serving cell of the second identification card, and/or increasing a cell measurement value of the non-interfered-with cell of the second identification card, so that the cell measurement value of the non-interfered-with cell of the second identification card is greater than the cell measurement value of the serving cell of the second identification card; and/or increasing a reselection threshold of the serving cell of the second identification card, so that the second identification card cannot access the serving cell. decreasing a cell priority of a serving cell of the second identification card, and/or increasing a cell priority of the non-interfered-with cell of the second identification card, so that the cell priority of the non-interfered-with cell of the second identification card is higher than the cell priority of the serving cell of the second identification card; and/or decreasing a cell measurement value of the serving cell of the second identification card, and/or increasing a cell measurement value of the non-interfered-with cell of the second identification card, so that the cell measurement value of the non-interfered-with cell of the second identification card is greater than the cell measurement value of the serving cell of the second identification card; and/or increasing a reselection threshold of the serving cell of the second identification card, so that the second identification card cannot access the serving cell.
