Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of method, Mobility Management Entity, policy functional entity and user terminal of setting up carrying.
Background technology
(3rd Generation Partner Project 3GPP) has proposed System Architecture Evolution (SystemArchitecture Evolution, SAE) project to third generation partner program.The network configuration of SAE is as shown in Figure 1.Among Fig. 1, (Mobility Management Entity MME) is in core network to move administration-management reason entity; Be responsible for mobile management, function comprises the carrying control of core net, to gateway (ServingGateway; SGW) and PDN Gateway (PDN Gateway PDN-GW) selects authentication etc.SGW is responsible for user terminal (User Equipment, the UE) transmission of user plane data, forwarding and route switching etc.PDN-GW mainly is responsible for being connected with the PDN network, is UE distributing IP address etc."Policy and Charging Rules Function (Policy and Charging Rules Function; PCRF) entity is responsible for CAMEL-Subscription-Information, Internet protocol ability access network according to the user (IP Capability Access Network, IP-CAN) information generating such as type, IP-CAN ability is used to carry the strategy and the charging regulation information of foundation.
SAE supports the UE roaming; When UE from a Public Land Mobile Network (Public LandMobile-communication Network; When PLMN) roaming into another one PLMN; The routing mode of UE data has two kinds of selections according to the CAMEL-Subscription-Information of UE: a kind of is that this mode is commonly referred to ownership place route (home routed) with the data route recurrence possession of UE; Another kind is that the UE data are exported in the roaming place, and this mode is commonly referred to local breakout (local breakout).
Fig. 2 shows the schematic diagram of home routed mode.As shown in Figure 2, the UE that is positioned at access zone network is through the PDN-GW of visit ground SGW with data route recurrence possession, and the PDN-GW through ownership place is connected to external network again.
Fig. 3 shows the schematic diagram of local breakout mode.As shown in Figure 3, the UE that is positioned at access zone network is connected to external network through the PDN-GW that visits ground again through the PDN-GW that visit ground SGW routes data to visit ground.
The main distinction of home routed and this dual mode of local breakout is the selection of PDN-GW.All media datas of UE all are connected to external network through PDN-GW.When UE adopted home routed mode, all media datas at first needed route to return the possession network; When UE adopted local breakout mode, the media data of UE can be directly from exporting to external network with visiting.With respect to home routed form, the benefit of local breakout is in the network on visit ground, to realize the data route, and need not take the network of ownership place, thereby saves Internet resources.
The selection of PDN-GW mainly be according to UE APN (Access Point Name, APN) and CAMEL-Subscription-Information.If the CAMEL-Subscription-Information of UE allows in the roaming place network allocation PDN-GW, then distribute PDN-GW in the roaming place; If fail to find PDN-GW in the roaming place, or the PDN-GW that indication does not allow to use the roaming place network in the CAMEL-Subscription-Information of UE, then in belonging area network, seek and connection PDN-GW.
Also introduce the IMS subsystem among the 3GPP.Concrete, IMS is at packet switching (PacketSwitched, the subsystem that PS) superposes on the territory among the 3GPP.IMS supports UE to carry out the IMS multimedia service through various packet switching Access Networks access IMS networks, and the son exchange Access Network that the most often uses at present is IP-CAN, and for example GPRS (General Packet Radio Service, GPRS), SAE.
Access point is appreciated that between UE and selected service the ip router that is connected being provided.The example of this service such as MMS, IMS.Same access point possibly provide multiple above-mentioned service.UE need know to service provide the APN that entity (like MMS, IMS etc.) provides access (Access Point Name, APN)-address of PDN-GW.A PDN-GW possibly provide different services, can be by different APN visits.
In research and practice process to prior art, the inventor finds to exist in the prior art following problem:
Prior art only is to judge according to APN and SAE CAMEL-Subscription-Information, supports that in the SAE system UE sets up default bearing (default bearer) with the mode of local breakout, promptly selects the vPDN-GW of roaming place under the situation of localbreakout.And different IMS business possibly need to set up default bearer with the mode of local breakout or home routed respectively.Scheme by above-mentioned prior art; According to APN and SAE CAMEL-Subscription-Information; In the SAE system, support local breakout if judge UE; Then can set up default bearer, promptly select vPDN-GW, and not consider that concrete IMS business sets up the mode that default bearer needs with the mode of localbreakout.Like this; If the IMS service needed of UE request is set up default bearer with the mode of homerouted; The default bearer that then sets up with local breakout mode in the prior art can not satisfy the demand; In this case, the carrying between the vPDN-GW of needs dismounting and roaming place, and the carrying between foundation and the ownership place hPDN-GW.The process of rebuilding is removed in this carrying can cause the wasting of resources, makes the session elongated user experience variation that makes settling time simultaneously.
