Description
Technical field
The present invention relates to mobile communication technology field, particularly a kind of methods, devices and systems of accessing terminal to network.
Background technology
The method of accessing terminal to network is different according to specific network environment, there is very big difference.In GPRS (General
Packet Radio Service, GPRS) in data network, GGSN (Gateway GPRS Support
Node, gateway GPRS serving node) as gateway GPRS serving node, with SGSN (Serving GPRS Support Node,
GPRS serving GPRS support nodes) together carry out GPRS session management, and to be also accomplished to external IP (Internet protocol,
Internet Protocol) packet network interface function.From the viewpoint of packet service network, it is addressable GPRS that GGSN, which just looks like,
All terminal IP router in network, the exchange of the routing iinformation for completing terminal and packet service network.

GPRS cellphone subscribers will be by wireless mode online, it is necessary first to APN (Access Point are set on mobile phone
Name, APN), initiate activation process.On GGSN, APN is used to determine which packet network GPRS mobile phones are linked into.
The APN information that SGSN is carried by activating in request message, to DNS (Domain Name Server, name server) parsings
Go out to need to access by which GGSN, then notify GGSN to create PDP (Packet Data Protocol, packet data protocol)
Context activation.During GPRS cellphone subscribers surf the Net, GGSN selects different access networks according to APN.
From Fig. 1 and foregoing description process it will be appreciated that this parameter of APN to serve comparison in whole business procedure crucial
Effect, terminal APN for using when activating context determines which business network he will access.
On the basis of above-mentioned principle, in order to simplify user APN setting, a kind of implementation of existing technology is：
One APN is only set to terminal.When terminal needs to access different business networks, it is desirable to use different user names.It is i.e. every
One user name is corresponding with a business network.So, on GGSN, it is possible to determine that user is actually subjected to by user name
The business network of access, so that it correctly be accessed.That is above-mentioned technical proposal is utilized, user can be allowed to use one
Individual APN accesses GGSN, and it is possible to using different user names, the different business network for accessing.

When, use different APN (such as one is internetA, and another is internetB).But, when the two operations
Business is merged for some reason, and an APN is only used only after merging (such as using internetA).At this moment, though
Right internetB has not been used, but if requiring that original this certain customers for using this APN of internetB are made into
Using internetA, operator will be difficult that operation (is on the one hand due to notify that user and guides how user changes one by one
Feasibility is small in actual operation, realize difficulty big, the reason for being on the other hand likely due to terminal, and can not modify).That
, would have to require that original this certain customers for using this APN of internetB still can use internetB to access.
But can not but use internetB to be linked into business network in the prior art, so above-mentioned prior art can not realize this
One function.
Further, it is a special case that Liang Ge operators, which merge, integrates, all exists this as long as being related to similar APN
Problem.Such as one operator when initial stage is carried out different business in operation there is provided multiple APN, but with the product of operation experience
It is tired, it is found that at this moment these APN its practical same APN carrying just can be also to may require that carrying out similar APN integrates.Therefore,
In the prior art, as long as having carried out APN integration, then it can not be linked into using non-existent APN in corresponding business network.
That is, at least there are the following problems in the prior art：
When needing user to be linked into according to the APN used originally in other networks in addition to the APN map networks,
Have no idea to provide a user a solution, to realize that user has access to former APN on the premise of former APN is still used
