Embodiment Construction

[0034] The main purpose of the present invention is to realize the cdma2000 / HRPD dual-mode terminal, which is characterized in that the terminal can receive instructions from the current network, analyze the instructions, and combine the current terminal status and user commands to switch between networks.

[0035] In the following description, detailed descriptions of known functions and structures will be omitted in order to make the subject matter clearer.

[0036] In order to be able to support switching between networks according to the instructions of the network, the current state of the terminal and the user's command, the parts included in the dual-mode terminal and the basic functions that each part should complete are as follows:

[0037] Antenna 101

[0038] Used to receive and transmit wireless signals, the antenna should be designed to be sensitive to the frequencies used by both the cdma2000 network and the HRPD network.

[0039] wireless module 102

[0040] R...

Abstract

It is a network switching device according to the network instructions. The controlling module is to control the all relating modules in the controlling end and control the conversion between the cdma2000 modem and the HRPD modem. The cdma2000 modem is used to encode and decode of the data and the order, extending the frequency and analysis of it, modulation and demodulation; the HRPD modem is used to encode and decode of the data and the order, extending the frequency and analysis of it, modulation and demodulation; the memorizer is used to store the needing data for the terminal normal working; the conversion components controlled by the signal of the controlling module connects the wireless part into the cdma2000 modem or HRPD modem; the wireless module connected with the modem through the conversion components does the conversion between the baseband digital signal and RF analog signal which is received and transmitted by the antennas. The invention can solve the frequency detecting of the double module moving terminals in the past.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a mobile terminal that switches between High Speed ​​Packet Data (hereinafter referred to as HRPD) and Code Division Multiple Access 2000 1x (hereinafter referred to as cdma2000 1x) networks according to network instructions. Background technique [0002] The cdma2000 1x network is a mobile network that provides voice services and low- to medium-speed data services to users, and the HRPD network is a mobile network that provides high-speed data services to users. In practical applications, HRPD networks mostly appear in the form of joint networking with cdma2000 1x, that is, the cdma2000 1x system and the HRPD system provide overlapping mobile communication services. Users use cdma2000 / HRPD dual-mode terminal (hereinafter referred to as MS / AT) to access HRPD network and cdma20001x network, but due to interference and other technical problems, at a certain moment, MS / AT can only access...
