Description

Method for orderly managing multiple APN concurrent networked data transmission channels

This application claims the priority of the Chinese Patent Application filed on October 10, 2013, the Chinese Patent Office, the application number 201310470063.9, and the invention titled "Method for Orderly Managing Multi-channel APN Concurrent Networked Data Transmission Channels", the entire contents of which are The citations are incorporated herein by reference.

Technical field

The invention realizes that a plurality of access point names (APNs) of a mobile terminal are successively activated and concurrently networked, and at the same time, a method for identifying, managing, and designating different APN networked data channels by different application softwares on the operating system of the mobile terminal is provided.

Background technique

Networking is the basic function of handheld mobile devices such as mobile phones. Because of the network, we have a variety of applications. Usually there are two APN list interfaces for mobile phone card-network connection. The first item: CMNET, the second item: CMCC MMS, the above item is selected, and the following MMS cannot be selected because there is no radio button. Sometimes after the machine is finished or the network data is wrong, the WIFI can connect to the Internet, and the mobile data cannot be connected to the Internet. In this case, you need to reset the APN. System Settings—Mobile Network—Access Point Name (APN)—Menu Key—Heavy Set to the default setting. When using iOS devices, you may find unusual Wi-Fi behavior, such as: hard to find or connect to the network; Wi-Fi signal strength is abnormal or disconnected. Unable to access the Internet, did not automatically connect to the Wi-Fi service interruption as expected. For ordinary users, APN (Access Point Name) is a set of parameters that are pre-configured or manually set on the mobile 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, etc. 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 mobile phone number, content conversion, and adaptive pre-judgment.

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 has matured and the standards are basically perfect. IPv6 is in the stage of coexistence and transition with IPV4. It can be said that the simultaneous networking of multiple APN channels by mobile phones 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 mobile operating systems, android, win phone, ios are mobile 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 phone 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.

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. Second, move The operating system on the mobile terminal does not provide a human-machine interface or interface for multi-channel APN configuration. The application layer cannot configure multiple APN applications. In addition, the operating system lacks an interface for application software to identify and manage multiple APN data channels.

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 network with the APN through the implementation of the network connection protocol. A mobile terminal is a computing device that supports wireless networking and can be used at any time. Access a variety of devices that access a variety of information, such as mobile computing devices such as laptops, PDAs, wireless network cards, and smart phones.

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.

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 presets 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.

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 default 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 embodiment of the present invention 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 sequentially sends one or more APN networking instructions to the multi-APN networking channel module. After receiving the networking instruction, the multi-APN networking channel module sequentially creates or allocates one or more channels according to the networking instruction. a virtual network unit, the virtual network unit sends a networking request to the mobile base station by using the driving module; after receiving the network connection request, the mobile base station sends a response signal to the driving module to the success or failure of the networking, and the driving module responds to the success of the network connection of the mobile base station. The message 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 assigned 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 another APN networking request again.

After receiving the APN networking command sent by the application layer, the multi-APN networking channel module has multiple APNs. The networking channel determines whether the APN networking parameter of the specified networking in the foregoing networking instruction matches the APN networking parameter of the currently allocated data transmission channel, and if so, directs the networking request to the connected packet data protocol PDP network, and feeds back the application. The network service access point identifier NSAPI or channel number actually used by the layer; if it does not match, dynamically allocate a virtual "channel number" for the connection in the order of connection request, and select an idle APN networking channel to fill an idle NSAPI handles the actual network networking request corresponding to a virtual channel by the caller. After the connection is successful, the channel number and NSAPI are fed back and the corresponding APN parameters and channel numbers are recorded in the APN channel parameter configuration information of the multi-APN networking channel module. Inside.

The multi-APN networking channel module contains a network interface function, and the application layer sends a network connection request according to the virtual channel identifier (constant value, string descriptor, channel instance object reference) or APN networking parameter in the interface function parameter; multi-APN networking channel module The APN channel parameter configuration information is saved after the APN networking parameter is successfully connected; different APN networking parameters represent different APN network channels.

After receiving the APN networking instructions sent by the application layer, the multi-APN networking channel module has the following three modes for creating multiple independent virtual network elements.

Implementation use case 1: Assign preset mode

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: Assign Presets and Dynamically Create Mixed 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 to the application layer. 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.

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 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 routing management module automatically binds the destination address specified by the application to the preset APN data channel; after the IP protocol stack of the operating system parses the destination address in the data sent by the application, the specified APN data channel is used according to the route in the routing table. Data transmission and reception.

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.

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, and such changes and modifications are considered to be within the scope of the invention.
