Description
Technical field
The present invention relates to the communications fields, in particular to a kind of method for connecting network and device.
Background technique
With the high speed development of internet application to flourish with information technology, people are more next to the dependence of internet
It is bigger, while with the quick emergence of mobile communication recent years, cause the computer for accessing internet and number of devices rapid
Increase, the especially development of 4G wireless access technology, is greatly promoted so that the message transmission rate of wireless access obtains, it can be with
Reach downloading 300Mbps, uploads the rate of 50Mbps, can satisfy the various online demands of user, wireless access terminal
Swift and violent hair is obtained, the internet access product of most families indispensability will be become.
APN (Access Point Name) is i.e. " access point name " that mobile terminal is interconnected by mobile network's access
The parameter that net must configure, which kind of access way it determines mobile terminal by access network.APN includes two
Point: network name and name of operator, APN Gateway GPRS Support Node (Gateway GPRS Support Node, referred to as
GGSN it is used to identify a specified extranets and a kind of Internet Service Provider of service (Internet Service in)
Provider, referred to as ISP), at Serving GPRS Support Node (Serving GPRS Support Node, referred to as SGSN)
In can according to APN by domain name system (Domain Name System, referred to as DNS) parsing obtain it is corresponding with this APN
The address GGSN.Usually in the network of operator, multiple APN can be arranged in GGSN, to provide it is different types of service and
Control the access authority and range of external network.When customer access network, according to the APN, SGSN in the request of user's transmission
Inquiry request is issued to dns server, finds the GGSN connecting with server platform, and user's request is sealed by GTP tunnel
Dress gives GGSN；User authentication information is sent by special line to Radius and is authenticated by GGSN；The confirmation of Radius certificate server
After being the request that legitimate user sends, to dynamic host configuration protocol (Dynamic Host Configuration
Protocol, referred to as DHCP) server requests distributing user address, and the confirmation letter for carrying station address is sent to GGSN
Breath；User has obtained the address Internet protocol (Internet Protocol, referred to as IP), so that it may normally access extranets
Network.APN is generally deployed in GGSN equipment or is logically connected on GGSN, and user passes through GGSN when surfing the Internet and acts on behalf of out
Go to external network.
Support " always on " i.e. always online function, wireless access terminal meeting in registration in the wireless access terminal 4G
Packet Data Network (packet data network, referred to as PDN) connection is established with network, so that it is logical to establish the transmission of IP data
Road, user can use the IP link having built up to carry out data transmission when needed.The APN that PDN is used is established to need to use
Family setting, the APN that user uses are assigned to user by operator.
The wireless access terminal 4G establishes PDN connection, has given the quick experience of the instant company of user, but right in registration
Higher in some pairs of communication security requirements or enterprise customer is with some problems, these user information safeties are more demanding or have
Self-built business network, these users need to establish connection with dedicated gateway when carrying out data communication, to access enterprise
The Intranet network of industry.But in the related art when only one PDN of progress is connect between network, connect in this PDN
Fixed APN used in connecing, that is, wireless access terminal in registered network, access be operator network, use fortune
The APN that battalion quotient specifies, the network connection established when user establishes dial-up connection are also to use the specified APN.Lead to network
It is lower to connect safety coefficient.
For, when being connected to the network, the low problem of safety coefficient not yet proposes have at present present in the relevant technologies
The solution of effect.
Summary of the invention

As can be seen from the above embodiments, the invention mainly relates to it is a kind of support register and dial using different APN method and
Terminal.In registration, the APN of the registration given using operator is registered for wireless access terminal, accesses network；It is needed in user
Dial-up connection is established, when doing data transmission service, wireless access terminal is gone to go to register with network, switches APN, gives using operator
The APN of fixed data transmission establishes PDN connection, transmits data for user, finishes to user's use, need to disconnect dial-up connection
When, wireless access terminal is gone to register again, and the APN APN for being switched to the given registration of operator is registered, network is accessed.This
It is that stringent user is required to consider to propose by information security.At this moment because requiring stringent enterprise-level for information security
User or proprietary user, same time wireless access terminal are only established a PDN with network and are connected, and do not establish a plurality of PDN connection,
When to avoid having a plurality of PDN connection again, network hacker or destruction molecule invade enterprise using one in a plurality of PDN connection
The dedicated network of user or proprietary user.
Wireless terminal supports registration and dialing to use different APN.When network is accessed in wireless access terminal, one is used
APN establishes PDN connection, accesses network；When user needs to establish dial-up connection, wireless access terminal goes registration (to go registration i.e.
For above-mentioned cancellation) registration when the PDN connection that has built up, switching APN establishes PDN with network using the APN of dialing and connects；
When user disconnects dial-up connection, registered network is removed, switching APN is the APN registered to use, establishes PDN connection registered network.
When carrying out APN parameter setting, classify to APN, options for user selection is provided, determines that user is to need to change registration
The APN APN that still dials, each APN corresponds to option category record, note set by user used when wireless access terminal is registered
Volume APN, the APN of dialing set by user is used when dialing.
When network is accessed in wireless access terminal, registration APN set by user is read, is established using registration APN and network
PDN connection.
Need to establish dial-up connection in user, after Sending dialled number instruction, wireless access terminal and network go to register, and read and use
Family setting for the APN that dials, establish PDN with network using the APN of dialing and connect, dial-up success.
Need to disconnect dial-up connection in user, after sending suspension instruction, wireless access terminal and network go to register, and read and use
Family setting is used to the APN that registers, establishes PDN with network using the APN of registration and connects, access network.
In user's click to dial link order, wireless access terminal has switched APN, and starts to establish connection with network
When, if link establishment is abnormal, wireless access terminal prompts dial-up connection foundation failure and network to go to register to user, reads
Take user setting for the APN that registers, establish PDN with network using the APN of registration and connect, access network.
It is connected in user's click to dial, dial-up connection is successfully established, and user is in use, if network is abnormal, network
Connection is abnormal to be terminated, and wireless access terminal and network go to register, read user setting for the APN that registers, use registration
APN establish PDN with network and connect, access network.And prompted to user, dial-up connection abnormal terminals, wireless terminal i.e. will be extensive
Multiple dial-up connection, wireless access terminal and network go to register, read user setting for the APN that dials, use the APN of dialing
It establishes PDN with network to connect, dial-up success.
