移动终端及数据包传输方法

Mobile terminal and data packet transmission method

Abstract

本发明公开了一种移动终端及数据包传输方法,移动终端包括基于预设接口连接的第一处理芯片、第二处理芯片、第一射频模块和第二射频模块,第一处理芯片包括第一应用处理器以及与嵌入式用户识别卡和实体用户识别卡连接的第一调制解调器,第二处理芯片包括第二应用处理器和第二调制解调器;第一调制解调器通过预设接口接收第二调制解调器发送的数据包获取请求,从嵌入式用户识别卡或实体用户识别卡中提取数据包;对提取的数据包进行压缩以缓存至预设接口的临时缓冲区buffer中,以供第二调制解调器从buffer中提取压缩后的数据包,以完成数据包的传输。本发明避免了数据包传输过程由于包容量值过大导致终端死机的情况。
The invention discloses a mobile terminal and a data packet transmission method. The mobile terminal comprises a first processing chip and a second processing chip which are connected based on a preset interface; a first radio frequency module; and a second radio frequency module. The first processing chip comprises a first application processor, and a first modulator-demodulator which is connected with an embedded subscriber identity module card and an entity subscriber identity module card. The second processing chip comprises a second application processor and a second modulator-demodulator. The first modulator-demodulator receives a data packet obtaining request sent by the second modulator-demodulator through a preset interface, extracts a data packet from the embedded subscriber identity module card or the entity subscriber identity module card, compacts the extracted data packet, then caches the data packet to a temporary buffer of the preset interface, so the second modulator-demodulator extracts the compacted data packet from the buffer, thereby finishing transmitting the data packet. According to the mobile terminal and the method, the condition that the terminal is crashed due to the fact that a capacity value is too high in the data packet transmission process is avoided.
