Description
Technical field
The present invention relates to moving communicating field, particularly relate to a kind of data route control method and system.
Background technology
Continuous lifting along with radio interface rate, in addition the increase of data user, future customer data volume can present fulminant growth, and existing core net network is inevitably impacted by this, and existing core network element has to carry out dilatation just can provide the user satisfied service.Consider that the data increased mostly are what internet business caused, mobile operator wishes to carry out local internet data distribution on the basis of existing network not changing, avoid mass data impact core net and disclosure satisfy that user's request, thus propose the concept of local IP access.
The introducing of Home eNodeB (HNB, HomeNodeB) extends the range of application of local IP access.Home eNodeB is as the dedicated resources of certain user, it is deployed in the private sites such as family, group, company or school to use, it is primarily to and provides the user with higher service rate and reduce the expense used required for high rate services, make up the deficiency that existing distributed cellular radio communication system covers simultaneously.IP device in other IP device of home network, enterprise network can be conducted interviews by user by Home eNodeB, and this application is also referred to as local IP access, because data stream will not be transmitted by core net.3GPP normal structure definition local IP access function includes the selection IP transmission shunting (SelectedIPTrafficOffload being applied to the access of Internet network, SIPTO) and the local IP of the access being applied to local network IP device access (LocalIPAccess, LIPA) two kinds.
In order to realize local IP access function, network needs set up the gateway performing data distribution function, Fig. 1 is local IP access and the data flow path schematic diagram of tradition core net access, data distribution gateway can and wireless side network element close set or near wireless side network element (namely external), it is also possible to and femto gateway close set or near femto gateway (namely external).For supporting the user of local IP access, it is possible to set up traditional core net and access data path and local IP access data path simultaneously.As it is shown in figure 1, for the connection of local IP access, local IP access data path is from terminal to wireless side network element to data distribution gateway, and data are transmitted without core net.In order to realize the terminal local access to other IP device of home network or internet, it is possible to set up two local IP access and connect, Article 1 local IP access data path directly accesses the Internet (internet ip connects, namely SIPTO connects).Article 2 local IP access data path directly accesses other IP device of home network (home network IP connects, namely LIPA connects).
Fig. 2 show the system architecture schematic diagram performing local IP access, and wherein data distribution gateway can close with wireless side network element and set or set up separately, and this framework is for Home eNodeB situation.The user uplink local IP access data that Home eNodeB receives send from the interface between Home eNodeB and data distribution gateway, the descending local IP access data of user that data distribution gateway receives also send from this interface, this interface has GTP-C and GTP-U protocol stack, not yet has standardized title.Local IP access connection is applied to data distribution gateway by chain of command network element by gateway and is managed.Packet data gateway is used for forwarding core network data.Core net up-downgoing data are sent by Home eNodeB, gateway, packet data gateway.S1-MME, S1-U, S5 interface in framework is standard interface, and the present invention does not do concrete function and describes.
Should be used for from local access of Home eNodeB, be mainly used in family, enterprise supports local network and the access of Internet or other specific IP network.Needs for family, company manager, it is possible to only allow certain user that one class network is conducted interviews, for instance to be only capable of carrying out LIPA access or being only capable of carrying out SIPTO access.User connects the data can distinguished the data to LIPA access or SIPTO is accessed by PDN, but, local gateway only plays forwarding effect, user's malice is passed through to the behavior of LIPAPDN connected reference SIPTO network, local gateway does not have supervisory function bit, for this problem, it is typically in local gateway at present to arrange fire wall and carry out the route test of data, but, adopt in this way, if accomplishing the control of user class, it is necessary to carry out a large amount of configuration specific to user on local gateway, thus realizing comparatively laborious.
Summary of the invention
In view of this, present invention is primarily targeted at a kind of data route control method of offer and system, it is possible to avoid carrying out the configuration specific to user on local gateway, simplify operation, and be easily achieved.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
