Mobile terminal wireless internet access network speed calculating method and device

Provided is a mobile terminal wireless internet access network speed calculating method and device. The mobile terminal wireless internet access network speed calculating method comprises the steps of determining the time period portion with maximum network flow of a mobile terminal according to internet access records of the mobile terminal within unit time; dividing each time period of the time period portion into multiple sub time periods, respectively calculating the network speeds of the sub time periods according to the internet access records correlative with the sub time periods; finding out a sub time period portion with higher network speed from all sub time periods included by the time period portion and using an average value of the network speed of the sub time period portion as the network speed of the mobile terminal within the unit time. The corresponding device comprises a time period selection module, a first calculation module and a second calculation module. According to the mobile terminal wireless internet access network speed calculating method and device, the wireless internet access network speed of the mobile terminal is calculated through second iteration, and an internet access network speed value of a mobile phone can be accurately calculated.
