Problems solved by technology
Network coverage includes overlapping parts. For example, the coverage areas of the second-generation communication network system (2G) and the third-generation communication network system (3G) may have overlapping areas. When both 2G signals and 3G signals are unstable in the overlapping areas, The mobile terminal may frequently choose to access between the two network systems, resulting in ping-pong switching phenomenon
The ping-pong switching operation of the mobile terminal will increase the network load, affect the network quality, cause problems such as signal loss and low call completion rate, and at the same time, the power consumption of the mobile terminal will also increase

Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0051]Ping-pong switching phenomenon refers to the fact that in the area covered by multiple communication network systems, due to the instability of signal quality, terminals in overlapping areas frequently reselect among multiple communication network systems. For example, under the China Mobile network, the optimal network It is often a 2G network, but the signal strength in the edge coverage area of the 2G network is very unstable, and the differe...

Embodiments of the invention provide a method and device for reducing ping-pong switching of a terminal, the method comprising that when detecting the number of times that the terminal is reselected to a same communication network system exceeds a preset time, the terminal determines whether the terminal currently selects and resides in an optimal communication network system; if the terminal currently selects and resides in the optimal communication network system, a re-selection condition is changed into a first re-selection condition, and time T1 is delayed; after the time T1 elapses, if the terminal detects there is a non-optimal communication network system that makes the terminal satisfy the first re-selection condition, time T2 is delayed and whether the terminal always satisfies a second re-selection condition is monitored within the time T2; and after the time T2 elapses, if the terminal always satisfies the second re-selection condition, the terminal re-selects and resides in the non-optimal communication network system. The method and the device can reduce effectively occurrence of ping-pong switching of a terminal, decreases problems lost of signal and low call completion ratio caused by ping-pong switching, and reduces power consumption of the terminal.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for reducing terminal ping-pong switching. Background technique [0002] When the mobile terminal can support different mobile communication networks, it can judge and reselect the network it resides on based on factors such as network signal strength and stability. Network coverage includes overlapping parts. For example, the coverage areas of the second-generation communication network system (2G) and the third-generation communication network system (3G) may have overlapping areas. When both 2G signals and 3G signals are unstable in the overlapping areas, The mobile terminal may frequently choose to access between the two network systems, thus causing a ping-pong switching phenomenon. The ping-pong switching operation of the mobile terminal will increase the network load, affect the network quality, cause problems such as signal loss and low call...
