Roam state display method of mobile communication terminal

Abstract

The invention discloses a roaming state display method of a mobile communication terminal belonging to the technical scope of the mobile communication terminal. It includes four stages: after searching the PRL, it is judged whether the searched system band is consistent with the frequency in the 11th stage; when the judgment result of the 11th stage is that the band is consistent with the frequency, it is judged whether to use the wildcard character network in the 12th stage; When the wildcard character network is used in the 12th stage, it is the 13th stage of judging whether its association relationship is consistent with the 1x system; when the judgment result of the 13th stage is that the association relationship is inconsistent with the 1x system, return to the 11th stage, and Stage 14 of the roaming indicator is displayed when the wildcard character network is not used or the association relationship at stage 13 is consistent with the 1x system. The characteristic of the present invention is that it can correctly display the roaming state of the hybrid mobile communication terminal running on 1x and EVDO simultaneously.

Description

technical field [0001] The invention belongs to the technical scope of mobile communication terminals, and in particular relates to a roaming state display method of a mobile communication terminal. In particular, it relates to a roaming state display method capable of displaying a hybrid mobile communication terminal operating in 1x and EVDO (EvolutionData Only). Background technique [0002] The general mobile communication system is a communication system implemented for moving objects such as people, automobiles, ships, trains, and aircraft, including push-button telephone systems, mobile phones (mobile phones, car phones), harbor phones, aircraft phones, mobile phones, etc. Public telephones (installed on trains, cruise ships, high-speed buses, etc.), wireless calls, wireless telephones, satellite mobile communications, amateur radios, ocean fishing wireless, etc. [0003] Such mobile communication systems include Advanced Mobile Phone Service (AMPS: Advanced Mobile Ph...

AI Technical Summary

Problems solved by technology

[0023] That is to say, in the prior art, when the PRL makes a roaming indicator read request for a DO system designated as a wildcard character network, it does not consider the association relationship, so it is easy to read the roaming indicator from other systems.

[0024] In addition, there is a limitation of not displaying the roaming indicator of the existing EVDO system
