Embodiment Construction

[0020] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is a schematic flow chart of the method for establishing a data connection in this application. Such as figure 1 As shown, the method includes:

[0022] In step 101, each operating system in the terminal initiates a bottom layer data connection establishment request to the RIL by using the APN of the system.

[0023] Each operating system in the terminal has its own APN, and the APNs of these different operating systems may be the same or different. Each operating system in the terminal performs processing independently of each other. The processing of one operating system A is used as an example for illustration below, and the terminal in this application supports multiple operating systems at the same time.

[0024] The operating system ...

Abstract

The invention discloses a method for establishing data connection on a multi-operating system terminal, and the method comprises the following steps: any operating system on the terminal initiates an underlying data connection establishment request to a radio interface layer RIL by using an access point name APN of the system, and the data connection establishment request carries an identifier of the corresponding operating system; the RIL notifies a baseband device of the terminal to establish a bottom layer data connection for the any operating system, and configures routing information forwarded to the corresponding bottom layer data connection for the any operating system; the routing information is used for routing data from any operating system to an underlying data connection established for the operating system, and is also used for routing data from any underlying data connection to the operating system corresponding to the underlying data connection; wherein the terminal allows more than two operating systems to run at the same time. By applying the method and the device, different operating systems can simultaneously use respective data connections to carry out data transmission.

Description

technical field [0001] The present application relates to communication technology, in particular to a method for establishing a data connection on a multi-operating system terminal. Background technique [0002] The process of establishing a data connection between the mobile terminal and the network generally includes: the operating system of the terminal sends a data connection establishment request to the baseband device (such as a modem) of the terminal through the radio interface layer (Radio Interface Layer, RIL), and the baseband device establishes a connection between the terminal and the network. data connection between. Among them, RIL is used as an adaptation layer to adapt to various baseband devices, so that the data of the operating system can be transmitted using the data connections established by various baseband devices. [0003] The current multi-operating system terminals only support the simultaneous use of one data connection for Internet access when ...
