Mode switching method and mobile terminal

Abstract

The invention provides a mode switching method and the mobile terminal, for switching between multiple network modes, and the mode switching method comprises the step of: if the mobile terminal is under the cover of the first network, when the signal of the first network is lower than a threshold value, the mobile terminal will search for the second network and switch the mode according to the searching result. Thus, it implements self-adapting switching between different networks and has advantages of a double-mode form, and implements smooth transition between different networks.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a mobile terminal that supports multi-mode switching, and a mobile terminal that can autonomously initiate mode switching according to changes in external network conditions when the mobile terminal is in any mode, so as to realize switching between different modes. method to switch between modes smoothly. Background technique [0002] The PHS system is a micro-cellular system. When the coverage of the cell is not good, the call quality of the PHS mobile phone is very poor. However, if the public network coverage is increased, it is necessary to increase the investment to repurchase the base station. At the same time, because many networks have insufficient coverage Good areas are indoors, and adding base stations indoors is often difficult to promote because users are worried about radiation. For this reason, the China Fixed Network and Terminal Alliance promotes L...

Problems solved by technology

[0004] Therefore, we can see that among the three existing modes, the single mode (PHS mode or cordless mode) cannot achieve smooth switching between the two networks, and the user must intervene manually. , the mode switching is performed through the menu selection, which is very inconvenient for the user to use

Lingtong cordless mode requires the mobile phone to receive and monitor two networks at the same time, so it can solve the inconvenience caused by manual switching. The PHS mobile phone can automatically search periodically, so as to update the mobile phone in time when the network coverage changes. Standby status, however, this "Lingtong cordless mode" is that the PHS mobile phone is in standby under two networks at the same time, which also brings certain problems: Problem 1: Since 2 networks must be in standby, the mobile phone must receive 2 networks The information takes a long time, and the user may feel that after the first call is completed, the user must stay for a while before making the second call. This stay time is obviously longer than that of the single-mode case.

[0005] Because this residence time is used to receive network information, it is enough to receive only one network information in single-mode, and two must be accepted in dual-mode, so it takes a long time

Question 2: If one network signal is poor and the other network signal is good, then the PHS mobile phone will standby under the network with good signal, and at the same time, periodically and regularly search for another network, thus increasing the power consumption of the mobile phone and causing the mobile phone to stand by The time is shortened. Since Linktone Cordless mainly solves the problem of poor public network coverage, it is very common that the public network signal is poor and the private network signal is good. Another situation is that when you leave the room, the public network signal is good and the There is no private network signal. These two situations are very common, but they meet the situation that we mentioned that periodic network search leads to increased power consumption.

Question 3: One network is good and the other network is not good. The PHS mobile phone searches for the network periodically, which may lead to loss of paging messages during the network search process and cause call loss
