The invention discloses a
cell measurement method and a related device. The method comprises the steps of updating a
cell measurement policy of a mobile terminal, wherein the updated
cell measurementpolicy is used for indicating a resource used in cell measurement, the resource comprises a
radio frequency resource of an auxiliary antenna of the mobile terminal, a
master card of the mobile terminal accesses a first cell of a first network at present, and a slave card of the mobile terminal accesses a second cell of a second network at present; and according to the updated cell measurement policy, measuring a third cell of a third network supported by the
master card and measuring a fourth cell of a fourth network supported by the slave card by using the
radio frequency of the auxiliary antenna of the mobile terminal in a cell measurement period, wherein the first network and the third network are heterogeneous mobile communication networks, and the second network and the fourth networkare heterogeneous mobile communication networks. Through adoption of the method and device,
data transmission delay is shortened, further, data is transmitted more timely.
