Embodiment Construction

[0026] In order to better describe the present invention, the present invention will be further described below through specific examples.

[0027] For dual-mode dual-standby mobile phones, until now, there is no mobile phone solution that can integrate TD-SCDMA and CDMA EVDO in one baseband solution.

[0028] This scheme is based on the integration of two mobile phone schemes into one mobile phone.

[0029] The specific embodiment of the present invention is as follows:

[0030] 1: Feature phones that support TD-SCDMA and CDMA EVDO dual-mode dual-standby - mainly CDMAEVDO mobile phone solutions, such as Figure 1 shown.

[0031] Use Qualcomm's CDMA EVDO solution, plus a TD-SCDMA module (such as Tianqi, Datang, Kaiming, Spreadtrum, etc. TD-SCDMA solution).

[0032] In this scheme, the Qualcomm CDMA EVDO scheme is the master, and the TD-SCDMA module is the slave. All interface operations and applications are based on Qualcomm's BREW (Binary RuntimeEnvironment for Wireless, ...

Abstract

The invention discloses a double-mode double-standby mobile phone of TD-SCDMA and CDMA EVDO, belonging to the technical field of mobile communication. The invention includes a TD-SCDMA mobile phone scheme module and a CDMA EVDO mobile phone scheme module. The user can use TD-SCDMA and CDMA EVDO at the same time. The invention brings convenience for users.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a dual-mode dual-standby supporting two communication modes. Background technique [0002] With the development of communication technology, there are many modes of mobile communication, there are many mobile communication standards, such as GSM / GPRS / EDGE, CDMA 95 / 2000 1X, CDMA 2000EVDO (Evolution Data Only), WCDMA / HSDPA / HSUPA and TD-SCDMA with China's independent intellectual property rights, etc. China Mobile and China Unicom are now constantly releasing GG dual-card dual-standby mobile phones with GSM / GPRS and CDMA 95 / 2000 1X dual-mode dual-standby (GC dual-mode dual-standby) and dual GSM / GPRS cards. The mobile phone can meet the needs of users who have one GSM card, one CDMA card and two GSM cards. [0003] It is estimated that by the end of 2007, TD-SCDMA will be fully licensed; CDMA 2000EVDO network will also be licensed. Thereafter, there will b...
