A dual-mode intelligent mobile terminal and the corresponding internal communication method

Abstract

The invention relates to a dual-mode intelligent mobile terminal and the internal communication method thereof; wherein, the mobile terminal is internally and newly provided with a three port RAM (2), and a driving port and a driven port are respectively connected with an application processor (1), a first wireless communication sub-system (31) and a second wireless communication sub-system (32) correspondingly. The method comprises that two memories inside the three port RAM are divided into an uplink data region and a downlink data region; the data is written into the uplink data region corresponding to the memories and reads the data in the downlink data regions of all memories; the first wireless communication sub-system and the second wireless communication sub-system write the data into the downlink data regions of the three port RAM which are corresponding to the memories from the port and read the data in the uplink data regions which are corresponding to the memories from theport. The terminal and the internal communication method greatly improve the speed of the data communication between the processor module and the dual-mode wireless communication sub-system inside the terminal by taking the three port RAM as a data communication media.

Description

technical field [0001] The invention relates to a mobile terminal, in particular to a dual-mode intelligent mobile terminal and an internal communication method thereof. Background technique [0002] TD-SCDMA (Time division synchronous code division multiple access Time division synchronous CDMA, hereinafter referred to as TD-SCDMA) is one of the 3G (3rd Generation mobile communication) communication standards, with strong data service capability, high call quality and large user capacity , and domestic enterprises have a large number of core patents, mature technology and low patent fees. At present, a large number of TD-SCDMA 3G test network networks in China have begun to be constructed and deployed, and a large number of TD-SCDMA mobile terminals have also appeared one after another. Since there is a process in the construction of the TD-SCDMA network, there is also a gradual transition process in the use of users. Therefore, in order to make up for the problem of insuff...

Problems solved by technology

As a mobile terminal that supports 3G networks, higher requirements are placed on the processing capabilities of the terminals. Smart mobile terminals with dedicated application processors (APs) will occupy a large proportion of 3G networks. The existing 3G Dual-mode intelligent mobile terminal, the system structure is as follows figure 1 As shown, it includes two wireless communication subsystems and AP module 3, namely: application processor (APPLICATION PROCESSOR, hereinafter referred to as AP), in the figure, the universal asynchronous receiving / transmitting device UART or Communication methods such as Universal Serial Bus (USB) have a slow transmission rate. Although the USB communication method can meet the current application, for the future high-speed data requirements, due to its complex protocol, the real usable data transmission The rate is relatively low, so it does not meet the requirements of future high-speed data services. In addition, the development difficulty and power consumption of mobile terminals are relatively large
