Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] refer to figure 1 , shows a schematic structural diagram of an embodiment of a dual-mode terminal according to the present invention. As shown in the figure, it includes four parts: the host part 1, the slave part 2, the speech unit 3 and the user identification card unit 4.

[0019] Wherein, the host part 1 includes a main baseband processor unit 11 and a dual-mode radio frequency unit 12 . Described dual-mode radio frequency unit 12 comprises the radio frequency part of two kinds of mobile communication standards, such as TD-SCDMA and GSM, is used as radio frequency receiver and radio frequency transmitter, and its inside further comprises radio frequency filter, low noise amplifier, mixer , pulse generator, power amplifier, etc.; when used as a transmitter, the digital signal from the main baseband processor unit 11 generates a pulse sequence after passin...

Abstract

The invention discloses dual mode dual standby terminal, which comprises a dual mode single standby host computer composed of a dual mode radio frequency unit and a main baseband processor unit, a slave computer composed of a single mode radio frequency unit and a slave baseband processor unit, a voice unit and a user identification card unit, wherein the user identification card unit comprises a first user identification card and a second user identification card, the main baseband processor unit is connected with the slave baseband processor unit to control the slave computer, the voice unit and the user identification card unit are respectively connected with the main baseband processor unit and the slave baseband processor unit, and are controlled by the main baseband processor. Because the single mode radio frequency and baseband processor parts of the slave computer are additionally arranged, when work in a certain mode is started up by the host computer, the slave computer is simultaneously started up to work, thus the dual mode dual standby can be realized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a dual-mode dual-standby terminal. Background technique [0002] At present, TD-SCDMA terminals are compatible with GSM mobile communication standard, and have two modes: TD-SCDMA and GSM. Due to the small coverage area of ​​TD-SCDMA network, according to relevant specifications, it can automatically hop frequency when TD-SCDMA network does not meet the requirements of terminal transmission and reception. Go to the GSM network to continue working. It solves the problem of keeping the mobile phone on the network when it is beyond the range of the TD-SCDMA network, so as not to drop the line. However, TD-SCDMA terminal has only one mode to work after it is turned on. It can not solve the situation that TD-SCDMA and GSM are on the network at the same time and are on standby at the same time, that is, the dual-mode dual-standby function of TD-SCDMA and GSM.
