Technical field

The present invention is a system and method for implementing multiple network access concurrency and management of a plurality of access point names (APNs) on a mobile terminal, and providing a mobile terminal operating system and application software for concurrent data transmission and management using a plurality of different APN networks. method.

Background technique

With the development of mobile ad hoc networks, more and more services are running on their networks, and multimedia real-time services and high-traffic video services are becoming more and more demanding on the network. With the maturity of handheld Internet technology and the popularity of smart handheld devices, today's handheld devices have become the most frequently used network access terminals outside the computer. On the bus, in the subway, wherever you go, you will see people who are holding handheld devices to listen to music, receive emails, send Weibo, and watch news online. In particular, the powerful scalability of smart handheld devices and the rich variety of functions and applications they bring are even more fun for handheld devices. However, current handheld devices and operating systems have caused some inconveniences when using different methods to access the Internet. The most frequently asked about handheld devices is the problem of mobile Internet access. Our mobile phone needs to set the network access mode (APN) when surfing the Internet; different functions and third-party applications require different network access methods to support the Internet. The wireless access point is a key component responsible for mobile terminal management and coordination of communication between wireless and wired networks. It provides seamless, high-speed, transparent access services for mobile terminals roaming between subnets. For ordinary users, APN (Access Point Name, pick up Incoming point name) is a set of parameters pre-configured or manually set on the handheld device terminal for Internet access. For the mobile network, the APN is an indispensable identifier for routing user IP packets to the corresponding GGSN and the external network. The role of the APN is as follows: the APN is used as the route identifier: the SGSN queries the specific DNS server according to the APN. The GGSN IP address corresponding to the APN is used to determine the GGSN that the user should access. The APN is used as the service domain identifier: the GGSN sends the user's service flow to different service domains according to different APNs, and different service domains correspond to different services. Bearer networking mode, user ID acquisition mode, and accounting mode. Take the two APNs that are the earliest provided by China Mobile and are currently the most widely used by users - CMWAP and CMNET:

1) CMWAP APN

At the beginning of the design, CMWAP APN is mainly for HTTP-based services, such as WAP Internet browsing, MMS, and so on. With the continuous development of data services, in order to support the gradually introduced non-HTTP protocol services, the WAP domain has gradually evolved into a default service domain for most self-operated services and cooperative services by upgrading and configuring, and providing MMS to users. , PIM, streaming media, universal downloads, newsletters, music players, games and more. The CMWAP APN uses the WAP gateway as a proxy node for HTTP access, and provides some auxiliary functions for users, such as free input of handheld device numbers, content conversion, and adaptive prediction.

2) CMNET APN

CMNET is an APN set up for open Internet access services. Users can access the Internet using any protocol without any control and restriction policies, but also do not provide other accessibility features. When the CMNET APN is used, the mobile terminal accesses the GGSN through the access SGSN, and the service data stream is translated into the Internet through the NAT corresponding to the firewall of the GGSN.

The current IP protocol version IPV6 technology is mature, the standard is basically perfect, and IPv6 is in the process. The phase of IPV4 coexistence and transition. It can be said that the simultaneous networking of multiple APN channels by handheld devices is a requirement that will be widely used in the future. However, the current mobile terminal operating system lacks the corresponding interface and design for simultaneously networking multiple APN channels.

Currently, the world's three major handheld operating systems, android, win phone, ios are handheld operating systems that are accessed by a single APN application. At the same time, various applications can only use one and the same APN channel. When using different APNs, the handheld device needs to manually switch the APN channel. In actual use, different application software on a mobile terminal often uses a single different APN networking channel. Usually open the settings inside the mobile device only one Internet access point, such as "GPRS connection Internet" settings, enter the menu - Settings - Connections - Hosting - Internet. There may be a GPRS connection to the Internet, and no other mobile network connection can be found. When downloading QQ, the default is an access point. Even the selection cannot be selected. Therefore, the general user does not have the relevant professional. In the case of knowledge, it is usually not possible to automatically switch the implementation of different business network options to set the access point conversion. Most mobile phones currently do not support multipoint network access. If you want to play Weibo at the same time, you will encounter more troublesome situations. You need to manually set the network access method. Because this method needs to find out what network access point the software uses, the general Users can only help with the help of third-party APN management software. When browsing the web on the mobile phone, the mobile phone is downloading music through the music player; email and MMS should also be kept at all times. And whether or not the network access of these functions can be correctly judged is the complicated technical term of using WLAN, CMWAP or CMMAIL; in general, it is necessary to constantly set the network setting items on the mobile phone, and some toss, and may not achieve the desired the goal of. If you want to really play with your smartphone, you can experience the convenience and fun of the mobile Internet. You need more powerful mobile terminals and multi-point network concurrent access technology. At present, mobile phone systems that can truly achieve multiple access point technologies are rare.

The reason why the mobile terminal operating system and the application software cannot realize the concurrent networking of the multi-channel APN network is that the operating system on the current mobile terminal only provides one APN access channel or data link supply layer for data exchange. The application layer uses different APN data channels and must be switched. Secondly, the operating system on the mobile terminal does not provide a human-machine interface or interface for multi-channel APN configuration, and the application layer cannot configure, query, and manage the application of the multi-channel APN. Furthermore, the application layer cannot obtain the detailed content of the networking failure. The application implementation cannot be better improved. In addition, the operating system lacks an interface for application software to identify, manage, and monitor multiple APN data channels.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

1 is a schematic structural diagram of a multi-APN network concurrent system and a method for implementing the same according to the present invention.

detailed description

See Figure 1. In the preferred embodiment described below, the model supporting the mobile terminal multi-APN network concurrent system and its implementation method includes, in order, an application layer, a multi-APN networking channel module, a route management module, and a driver module; APN channel parameter configuration information and APN. The channel monitoring management module is embedded in the multi-APN networking channel module.

A multi-APN networking channel module for multi-APN concurrent networking and providing a networked multi-APN channel or data link for an operating system or application software, located at an application layer and an underlying driver of an application software including a mobile terminal operating system and an operating system Between modules. The multi-APN networking channel module is used for multi-APN concurrent networking and provides a channel or data link for networking multiple APNs for the operating system or application software.

The routing management module between the application layer and the underlying driver module, which is also located on the operating system and the operating system of the mobile terminal, uses the order management application to send and receive data before or after the application sends and receives data. APN data channel.

The application layer includes an operating system or application software on the mobile terminal.

A driver module is a driver module that contains the networking hardware of a mobile device. The networking hardware may be a baseband chip of the mobile terminal, and may also be referred to as a MODEM chip, and its main function is to connect through the network. The implementation of the discussion is connected to the APN. A mobile terminal is a computing device that supports wireless networking, and can access a type of device that obtains various kinds of information anytime and anywhere, such as a mobile computing device such as a laptop, a PDA, a wireless network card, and a smart phone.

The application layer configures or pre-defines the data in the APN channel parameter configuration information in the multi-APN networking channel module through the interface function in the multi-APN networking channel module through the human-machine interface or the application program.

The application layer application can directly implement the APN network connection by sending an APN networking request to the APN networking channel module. Different applications can send multiple different APN networking requests, and an application can send different APN networking requests multiple times. After the successful APN is established, the multi-APN networking channel module modifies the APN channel parameter configuration information according to the APN networking parameters.

Different APN data connection channels are distinguished by APN parameters, and different APN parameters are identified as different APN data networking channels. The parameters on the APN data connection channel for distinguishing different APN data networking channels include, but are not limited to, APN access point names, quality of service QOS levels, networking protocols, and the like.

The multi-APN networking channel module presets a plurality of APN networking channels, and each APN networking channel corresponds to a data connection of an APN network. After receiving the APN networking instructions sent by the application layer, the multi-APN networking channel module allocates pre-defined and/or dynamically creates multiple independent virtual network units.

In the APN networking instruction, the APN networking parameters are identifiers of different APNs that are networked, and different APN networking parameters represent different APN networks. APN networking parameters representing different APN networks include, but are not limited to, APN access point names, QOS levels, network protocols, and the like. Network connection protocols include but are not limited to Internet Protocol IPV4, IPV6 or IPV4/IPV6 for point-to-point links for multi-protocol Packet-transmitted PPP networking protocol or voice network PDP networking protocol.

The multi-APN networking channel module includes APN channel parameter configuration information and an interface function for modifying the multi-APN channel parameter table by the supply layer. The application layer modifies each APN channel parameter configuration information according to the virtual channel identifier, constant value, string descriptor, channel instance object reference, and APN networking parameters in the interface function parameters.

The data in the APN channel parameter configuration information identifies the APN networking parameters of each APN channel, and also identifies the APN network to which each APN channel is connected. The differences in APN networking parameters represent different APN networks. The APN channel parameter configuration information is used to identify the networking parameters of the APN network to which each APN networking channel is connected, and the actual networked APN of the current APN channel, including the parameter definition of the used APN channel and the number of idle APN channels.

The route management module defines certain specific APN network channel paths as the default and predefined path default paths of the application layer data networking. For example, the CMNET of IPV4 can be defined as the default route of IPV4, and the CMNET of IPV6 can be defined as the default route of IPV6. . This design makes the method designed by this solution compatible with traditional applications.

When the driving module executes the networking instruction of the multi-APN channel module, in addition to the feedback information upon success, when the networking operation fails, the detailed failure information is fed back to the multi-APN networking module, including but not limited to network timeout, no network signal, SIM Arrears, APN not open, APN parameter error and other news.

The specific implementation manner of the present invention in establishing and identifying an APN data channel can be divided into two steps:

1. Application layer establishes multiple APN networking channels

In the process of sending a network request, the application layer successively delivers one or more APN networking instructions to the multi-APN networking channel module, and after receiving the networking instruction, the multi-APN networking channel module according to the above networking instruction The virtual network unit sequentially sends or allocates to one or more virtual network units, and the virtual network unit sends a networking request to the mobile base station through the driving module; after receiving the sending network request, the mobile base station sends a response signal to the driving module whether the network is successful or not, and the driving module will The message of successful network connection responded by the mobile base station is sent to the multi-APN networking channel module, and the multi-APN networking channel module sets the parameters in each successful networking message to the virtual network unit created or allocated above. After one or more virtual network elements are created or allocated, the application layer initiates another different APN networking request, and the multi-APN networking channel module will again create or assign a new virtual network that exists simultaneously with the original virtual network element. Unit, and continue to send different APN networking requests again.

After receiving the APN networking instruction sent by the application layer, the multi-APN networking channel determines whether the APN networking parameter of the specified networking in the networking instruction matches the APN networking parameter of the currently connected data transmission channel, if If the match is made, the networked request is directed to the connected packet data protocol PDP network, and the network service access point identifier NSAPI or channel number actually used by the application layer is fed back; if not, the connection request is in the order of connection request. Assign a virtual "channel number" and select an idle APN networking channel to fill an idle NSAPI to handle the actual network networking request of the caller to a virtual channel. After the connection is successful, the channel number and NSAPI are fed back. The corresponding APN parameters and channel numbers are recorded in the APN channel parameter configuration information of the multi-APN networking channel module.

The multi-APN networking channel module contains a network interface function, and the application layer sends a network request according to the virtual channel identifier in the interface function parameter: a constant value, a string descriptor, a channel instance object reference, or an APN networking parameter; the multi-APN networking channel module passes The APN networking parameters save the APN channel parameter configuration information after successful networking; different APN networking parameters represent different APN network channels.

The multi-APN networking channel module is created after receiving each APN networking instruction sent by the application layer. The modes of multiple independent virtual network elements have the following three modes.

Implementation Use Case 1: Assigning predefined patterns

The operating system pre-defines the type of the APN channel in the APN channel order. For example, APN channel 1 is defined as CMNET, APN channel 2 is defined as MMS, and APN channel 3 is defined as CMWAP.

When the APN networking command is sent at the application layer, the APN networking parameters are not included, and the channel number is directly used for the connection.

After receiving the channel number networking command parameters sent by the application layer, the multi-APN networking channel module sends the predefined APN networking parameters to the driver module. After the networking is successful, the specified channel number is assigned to the application layer.

When the application layer sends an APN networking command, it can also use the APN networking parameter.

The multi-APN networking channel module parses the APN networking parameters in the APN networking command sent by the application layer. After the networking is successful, the predefined channel number is assigned to the application layer.

Implementation use case 2: Dynamic creation mode

The multi-APN networking channel module parses the APN networking parameters in the APN networking command sent by the application layer. After the networking is successful, dynamically allocates an idle channel number to the application layer.

Implement Use Case 3: Assigning Predefined and Dynamic Creation Modes

The operating system pre-defines the APN channel type according to the APN channel order. For example, APN channel 1 is defined as CMNET, APN channel 2 is defined as MMS, APN channel 3 is defined as CMWAP, and so on.

The multi-APN networking channel module parses the APN networking parameters in the APN networking command sent by the application layer. After the networking is successful, if it is a predefined APN channel, the predefined designated channel number is assigned. Use layers. Otherwise, dynamically create an idle channel number for the application layer.

2. The route management module identifies, manages, or specifies the APN data channel.

The routing management module between the application layer and the underlying driver module of the application software on the operating system and the operating system of the mobile terminal, in order to manage the data transmission and reception of the application before the application sends and receives data or during the process of sending and receiving data APN data channel.

There are four implementation use cases for the route management model. It should be noted that the following four implementation examples can be used in combination. That is, there are four management modes that can be used in combination:

Implementation Use Case 1: Application specified channel mode

The routing management module includes a socket socket interface, and a parameter for specifying a virtual channel number is set in the socket interface; after the routing management module takes out the above parameters, the data sent and received by the application is directed to the virtual channel number specified by the parameter. To achieve the sending and receiving of application data.

Implementation use case 2: Destination address binding routing mode.

The application calls the interface function in the routing management module to bind the destination IP address to be accessed in the routing table of the routing management module. After the IP protocol stack of the operating system parses the destination address in the data sent by the application, the routing table is used. The route passes the packet to the specified APN data channel.

Implementation use case 3: Send address specifies the routing mode.

When the application sends and receives network data, the IP protocol stack of the operating system parses the local IP address of the mobile terminal in the application sending and receiving data request, and uses the APN data channel corresponding to the IP address to perform data transmission and reception.

Implement Use Case 4: Default Path Mode.

The route management module automatically binds the destination address specified by the application to the predefined APN data channel; after the IP protocol stack of the operating system parses the destination address in the data sent by the application, the route is pressed. The specified APN data channel is used for data transmission and reception by the routes in the table.

When the request of the networked APN includes the proxy server address, the route management module automatically binds the proxy server address after the APN channel is successfully connected.

When the APN network of the networked APN requesting the network belongs to the APN type already defined by the operating system, the route management module automatically binds the destination address of the APN to the route in the case that the networked APN request does not include the proxy server address.

After the IP protocol stack of the operating system parses the destination address in the data sent by the application, the data packet is transmitted to the specified APN data channel according to the route in the routing table.

The APN channel monitoring management module monitors and manages the APN networking channel, including but not limited to the APN networking channel configuration, connection, disconnection, shutdown, switching, and data link information reporting.

The application layer configures, connects, disconnects, switches, and closes the APN channel through the interface function provided by the APN channel monitoring management module.

The APN channel monitoring management module collects the report message from the driver module, and feeds the message to the application layer in real time.

After the application layer uses multiple preset APN networking channels, once the application layer initiates a new APN networking request again, if the new APN networking request does not belong to the used APN networking network, the APN channel monitoring management module applies to the application. The layer feedback channel is full of messages.

The APN channel monitoring management module reports the application layer to the application layer through the system message channel once it receives the message that the driver module is connected, disconnected, or closed.

The reported messages include networking success and failure messages, as well as the real-time operating status of each APN networking link. The network failure message includes but is not limited to the network timeout, no network signal, SIM arrears, APN is not open, APN parameter error and other messages.

The application layer can configure, connect, disconnect, switch, and close any APN channel through the corresponding command of the APN channel monitoring management module through the human-machine interface or application.

What has been described above is only a preferred embodiment of the invention. It should be noted that a number of variations and modifications may be made by those skilled in the art without departing from the principles of the invention. For example, the program may be stored in a mobile terminal readable storage medium, optionally Each module/unit of the terminal in the above embodiment may be implemented in the form of hardware or in the form of a software function module. The present invention is not limited to the combination of any specific form of hardware and software, and is intended to be within the scope of the present invention.
