Problems solved by technology

Considering that the frequency bands of each mode in the 3G frequency band division are relatively close to each other, 3G-based dual-mode mobile phones will introduce interference when calling in dual-mode and dual-standby mode, resulting in a decline in service quality
If a dual-mode single-standby solution is adopted, end users will not be able to experience the convenience of dual-mode mobile phones
Therefore, mobile phone manufacturers hope to achieve dual-mode dual-standby even when the two modes may generate radio frequency interference. However, there is no ideal solution for realizing calls under dual-mode dual-standby.

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0021] Figure 1 shows the system architecture diagram of this embodiment. In the figure, the PHS module is an independent functional module that implements various functions of the PHS, and the DMC interacts with the PHS module through the AT command set. ARENA is the bottom platform, which realizes various business functions of TD. The dual-mode control module DMC (ZTE_BL dual-mode logic encapsulation layer in the figure) is introduced between the MMI (Man Machine Interface) and the dual-mode two protocol stacks (PS) to control the dual-mode business logic Separate from MMI, DMC interacts with the two protocol stacks. MMI is only responsible for the task processing of user logic, while DMC is used for centralized control and management of the underlying information and upper-level message commands, focusing on processing dual-mode business logic. Inc...

Abstract

A method for realizing network switch of double mode mobile terminal is provided, the double mode terminal comprises a first system I and a second system II modules, includes a system I single wait state, a system II single wait state, a system I / II double wait state, when the double module terminal is at the double wait state, the radio frequency of the system I interferes call of the system II. The method comprises: (a) the terminal cuts system I or system II network connection needed to be cut according to the target wait state and present wait state, closes corresponding system module; (b) the terminal starts modules of the system I or the system II according to the target wait state and present wait state, searches corresponding network to register; (c) storing new wait states. The invention avoides the problem of too long wait time when switching between modes, improves functionality and workability of double mode mobile phones.

Description

Technical field [0001] The present invention relates to the technical field of third-generation mobile communication, in particular to a method for implementing network switching by a dual-mode mobile terminal. Background technique [0002] The existing dual-mode mobile phones are nothing more than GPRS / GSM, CDMA / GSM and WCDMA / GSM. The realization of dual-mode is also different from each manufacturer. The frequency points of the two modes in dual-mode are far apart. , The mutual interference is low, so in this dual-mode mobile phone, it is generally dual-standby. Both modes can be in the standby state. When a call is made in one mode, the other mode does not need to be considered. Radio frequency interference. If the frequency points of the two modes in the dual mode are relatively close, considering the radio frequency interference, if the dual standby solution is adopted, when a call is made in a mode in the dual mode, the radio frequency interference of the other mode will cau...
