Description

Method and device for optimizing network switching and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for optimizing network handover, and a computer-readable storage medium.

Background

The current China telecom 2G (CDMA 1X) network is special, and generally does not broadcast surrounding 4G or 5G neighboring cells, so that after a mobile phone is dropped from a 4G/5G network and then stays in a CDMA1X network in a certain scene such as a basement, because whether a 4G/5G cell exists around the mobile phone cannot be obtained from a network broadcast system, the mobile phone cannot stay in the 4G/5G network in time even after moving to an area covered by 4G/5G.

Currently, mainstream chip manufacturers generally adopt the following methods:

the first method comprises the following steps: when the mobile phone resides in a CDMA1X network, the radio frequency of the mobile phone is frequently switched between a CDMA1X mode and an LTE search mode, for example, every 1 second, the radio frequency of the first 0.7 second works in the CDMA1X mode, so that the mobile phone is ensured to provide CDMA1X service; then 0.3 second is in 4G searching mode, at this time, the handset searches 4G signal, CDMA1X is not available.

The second mode is as follows: and setting a timer, after the timeout, searching whether a 4G network exists or not by the mobile phone, if so, residing the 4G network, and if not, continuing to work in the CDMA1X mode and starting the timer again.

However, the existing solutions have the following problems:

although the first method can ensure that LTE is searched as soon as possible, LTE needs to be frequently searched, power consumption is high, and CDMA1X is frequently interrupted, which may also affect normal operation of CDMA1X, and user experience is very poor.

The second method consumes less power if the timer is set longer, but cannot search for 4G in time as the first method does, i.e., the time interval to return to 4G is long. If the timer setting is short, like the first scheme, the LTE needs to be frequently searched, the power consumption is high, and the time interval for returning to 4G is short.

Therefore, the existing schemes cannot give consideration to the problems of low power consumption and fast network switching.

The optimized network switching device detects the characteristics of network transformation through the network change detection module 51, and controls the 4G 5G cell search module to search information according to the change condition of the network through the judgment change generation module 52, so that the accurate time for searching LTE or 5G cells can be captured as early as possible on the premise of not increasing power consumption, the time for returning to the 4G or 5G network from the CDMA1X network is shortened to the maximum extent, and the problems of low power consumption and rapid network switching can be considered.
