Description
Technical field
The present invention relates to the methods, devices and systems in mobile communication technology field, particularly a kind of accessing terminal to network.
Background technology
The method of accessing terminal to network has very big difference according to concrete network environment difference.At GPRS (General Packet Radio Service, GPRS) in the data network, GGSN (Gateway GPRS Support Node, the gateway GPRS service node) as the gateway GPRS service node, with SGSN (Serving GPRS Support Node, the GPRS serving GPRS support node) carries out the GPRS session management together, and will be accomplished to the interface function of external IP (Internet protocol, Internet Protocol) packet network.From the viewpoint of packet service network, GGSN just looks like to be the router of all terminal IP in the addressable GPRS network, is used to finish the exchange of the routing iinformation of terminal and packet service network.
As shown in Figure 1, be the process schematic diagram of a kind of accessing terminal to network of the prior art.Its access procedure is:
The GPRS cellphone subscriber will at first need be provided with APN (Access Point Name, APN) through the wireless mode online on mobile phone, initiate activation process.On GGSN, APN is used to determine which packet network the GPRS mobile phone is linked into.SGSN is by activating the APN information of carrying in the request message, to DNS (Domain Name Server, name server) parses to need to pass through which GGSN access, notify GGSN to create PDP (Packet Data Protocol, packet data protocol) context activation then.In the process of GPRS cellphone subscriber online, GGSN selects different access networks according to APN.
Can understand that from Fig. 1 and foregoing description process this parameter of APN has played relatively more crucial effect in the whole service process, the APN that terminal is used when activating context has determined which business network he will insert.
On the basis of above-mentioned principle, in order to simplify the setting of user APN, a kind of implementation of existing technology is: an APN only is set for terminal.When terminal need be visited different business networks, require to use different user names.Be that each user name is corresponding with a business network.Like this, on GGSN, just can determine the actual business network that will visit of user, thereby it is correctly inserted by user name.That is to say and utilize technique scheme, can allow the user to use an APN to insert GGSN, and, can use different user names, be used to insert different business networks.
If following situation: when disposing certain identical business (for example Internet inserts), what use is different APN (be internetA such as one, another is internetB) as two operators.But,, after merging, only use an APN (such as using internetA) when these two operators merge for a certain reason.At this moment, though internetB has not re-used, if but require this part user of original this APN of the internetB of use to use internetA instead, it (on the one hand is owing to notify the user to and guide the user how to be modified in that feasibility is little in the actual operation, the realization difficulty is big one by one that operator will be difficult to operation, possible on the other hand owing to terminal, and can't make amendment).The requirement of so, just having to used this part user of this APN of internetB still can use internetB to insert originally.But but can't use internetB to be linked in the business network in the prior art, so above-mentioned prior art can't realize this function.
Further, two operators merge just special case, integrate as long as relate to similar APN, all have this problem.Be provided with a plurality of APN when carrying out different business at the operation initial stage, but, find that its practical same APN carrying of these APN is just passable, at this moment also can need to carry out similar APN and integrate along with the accumulation of operation experience such as an operator.Therefore, in the prior art,, then can't utilize non-existent APN to be linked in the corresponding business network as long as carried out the APN integration.
That is to say that there are the following problems at least in the prior art:
When the APN that needs the user according to original use is linked in other networks except that described APN map network, having no idea provides a solution to the user, to realize that the user can be linked in other networks outside the former APN map network under the prerequisite of still using former APN.
