Background technology
In having the carrier network of a plurality of management domains, the business that operator provides can be divided into two kinds of the professional and local services of the whole network.Relevant management domain, the whole network business, local service are defined as follows:
Management domain---have relatively independent network, professional, the unit of management independence, for example a lot of operators divides different management domains according to province for unit usually, each management domain all has a plurality of access points, for example GPRS (General Packet Radio Service, hereinafter to be referred as: (the Serving GPRS Support Node of Serving GPRS Support Node GPRS), hereinafter to be referred as: SGSN), one or more gateways, the Gateway GPRS Support Node of GPRS network (Gateway GPRS SupportNode for example, hereinafter to be referred as: GGSN), and corresponding domain name system (Domain Name System, hereinafter to be referred as: DNS) server etc.;
The whole network business---the user towards network-wide basis provides, and at the whole network unified deployment and policy control is arranged, and the user of the whole network is no matter still can use such other business in the roaming place on ground, home to return to.
Local service---certain management domain is to a kind of own business that oneself user provides, and requires the user of this management domain to roam into other management domain and still can use this business.
When the user uses data service in the mobile communications network, that utilize usually at present is a kind of APN (Access Point Name, hereinafter to be referred as: mechanism APN) comes identifying user to want the external network of visiting, this time, access point apparatus utilized APN to resolve to control user's route, promptly controlled the user and with which gateway (for example GGSN of GPRS network) was connected.
In having the carrier network of a plurality of management domains, at certain class business, usually identical APN is used in the whole network unification, because the APN mechanism for resolving of standard is not considered user's home administrative domain information, the dns server of each management domain can only be stored the data one to one of APN and corresponding gateway, promptly these APN can only be pointed to the gateway of this management domain, as shown in Figure 1.In this system, belong to the user of different management domains no matter insert at which management domain, can both utilize the APN analytic ability, insert local gateway nearby, and then visit external network or service server, avoided the circuitous of route, be suitable for carrying out of the whole network business, the gateway that is each management domain can both insert unified operation system, and has all disposed corresponding business flow control and statistics strategy.
The APN mechanism for resolving of standard owing to when resolving, do not consider the information of user attaching management domain, can not adapt to carrying out of each management domain local service.For example management domain A will carry out certain local service A, its user roams into IAD B behind the management domain B, differ and have access to the server of the professional A that is positioned at management domain A inside surely, promptly allow to have access to, because a lot of at present professional controls, for example content charging, be to carry out at the gateway place, need be at the corresponding strategy of gateway place configuration, thereby can normally use professional A after roaming into other management domain for the user of management domain A, gateway except will opening all management domain A is to the access permission of management domain A interior business network, also need be at these gateway deploy professional control strategy identical with gateway A, for example content charging is at the recognition rule of professional A.
In order to support carrying out of local service, need strengthen the APN mechanism for resolving, in its parsing, consider its home administrative domain information, make the user no matter insert at which management domain, can be connected to the gateway device of user attaching management domain.This time, dns server need be stored the plurality of data item at certain APN:
(APN. home administrative domain information A, gateway A)
(APN. home administrative domain information B, gateway B)
For example application number is the APN mechanism that 200610098446.8 invention has proposed a kind of enhancing, after access point obtains user APN, (the InternationalMobile Subscriber Identity of this user's international mobile subscriber identity in the interpolation, hereinafter to be referred as: IMSI) label (comprising this user attaching regulatory domain information), through dns resolution, obtain the IP address of the gateway of user attaching management domain, and then be established to the connection of home administrative domain gateway.This mechanism makes that the user that moves at network-wide basis can access belonging management domain gateway, help operator and carry out separately local service at each management domain, yet this mechanism makes user's data connect at first wants route to return the management domain gateway that belongs to, and can cause unnecessary route circuitous for the whole network business.For the whole network business, after certain user of home administrative domain B inserted from management domain A, the path of " user, access point (home administrative domain A), gateway (home administrative domain B), service server " always was greater than or equals the path of " user, access point (home administrative domain A), gateway (home administrative domain A), service server ".
In having the carrier network of a plurality of management domains, the APN mechanism of standard is not suitable for carries out local service, though the APN of enhancing mechanism can be supported carrying out of local service, can cause meaningless route circuitous for the whole network business.And in the real network, in general, the whole network business and local service exist simultaneously, and simple APN APN mechanism machine-processed or that strengthen is not suitable for supporting simultaneously the whole network business and local service.
