Method and device for switching between data networks intelligently

Abstract

The invention discloses a method and device for switching between data networks intelligently. The method comprises the following steps: a. in areas covered by CDMA and WLAN, upward traffic and downward traffic of a mobile terminal over a period of time in the past are counted to judge whether an upward data service or a downward data service is to be executed chiefly; b. upward data rates or downward data rates of the CDMA and the WLAN in a period time in the future are predicted and calculated according to the judgment, the future upward data rates of the two networks are calculated respectively if the upward data service is to be executed chiefly, and the future downward data rates of the two networks are calculated respectively if the downward data service is to be executed chiefly; c. the network with large future data rate is chosen to execute the data service according to the result of the predicted calculation. Therefore, in the areas covered by multiple networks, the mobile terminal guarantees that the data service of the mobile terminal is kept to be executed on the network with large network rate, the network resources are optimized and utilized to the greatest extent, and the Internet experience of a user with the mobile terminal is improved.

Description

technical field [0001] The invention relates to a data network switching technology, in particular to a data network switching technology under the double network coverage of CDMA and WLAN. Background technique [0002] WLAN and CDMA networks are two important networks in the wireless network world. The former has high speed, but the coverage of wireless access nodes AP has certain limitations; the latter has strong mobility and a strong sense of the times. In contrast, the majority of users prefer WLAN with high speed. Because it is almost free, where there are WLAN hotspots, you can surf the Internet for free, and its network bandwidth is more advantageous, and its speed is far better than that of a CDMA network. [0003] With the popularization of WLAN and CDMA networks, most areas are under the double coverage of these two networks. Users hope to maintain the highest Internet speed at all times. Under different networks such as 3G CDMA, WLAN and other network coverage, ...
