Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method of generating strategy, Apparatus and system.
Background technology
In order to keep 3-G (Generation Three mobile communication system) in the competitiveness of the communications field, for user provides, speed is faster, the lower and more personalized Mobile Communication Service of time delay, simultaneously, reduce the operation cost of operator, third generation partner program (3GPP, 3rd Generation Partnership Project) standard operation group is just being devoted to the research of evolved packet system (EPS, Evolved Packet System).Whole EPS system is divided into wireless access network and core net two parts.
Wireless access network is by evolution base station (eNB, Evolved NodeB) and 3G radio network controller (RNC, Radio Network Controller) form, wireless access network is mainly responsible for the transmitting-receiving of wireless signal, by air interface and terminal, contact Radio Resource, scheduling of resource and the access control etc. of management air interface.Core net comprises home subscriber server (HSS, Home Subscriber Server), Mobility Management Entity (MME, Mobility Management Entity), Serving GPRS Support Node (SGSN, Serving GPRS Support Node), policy charging rule function (PCRF, Policy and Charging Rule Function), gateway (S-GW, Serving Gateway) and packet data gateway (P-GW, PDN Gateway).
Fig. 1 is the packet-based core networks (EPC of 3GPP and non-3GPP connecting system access evolution in prior art, Evolved Packet Core) structural representation, as shown in Figure 1, EPS comprises 3GPP connecting system and EPC, EPS supports 3GPP access, HSS is the permanent storage place of user contracting data, is positioned at the signing home network of user.MME is responsible for the processing of mobile management, Non-Access Stratum signaling and the chain of command correlation functions such as management of user mobility managing context.S-GW is the accessing gateway equipment being connected with wireless access network, forwarding data between wireless access and P-GW, and data are carried out to buffer memory.P-GW is the borde gateway of EPS and packet data network (PDN, Packet Data Network), is responsible for the access of PDN and the function such as forwarding data between EPS and PDN.PCRF is "Policy and Charging Rules Function entity, by receiving interface Rx, is connected with Operator Specific Service network, is responsible for providing charging control, online credit control, thresholding to control and service quality (QoS, Quality of Service).SGSN is the service support node of GEARN and UTRAN user access core network network, similar with Mobility Management Entity in function, is responsible for user's the functions such as position renewal, paging management and bearer management.
As shown in Figure 1, EPS system is also supported non-3GPP access.Wherein, mutual S2a, S2b, the S2c Interface realization of passing through of EPS system and non-3GPP access, P-GW is as the anchor point between 3GPP access and non-3GPP access.Non-3GPP access is divided into the non-3GPP access of credit and the non-3GPP access of non-credit.Wherein, the non-3GPP access of credit can directly be connected with P-GW by S2a interface, and S2a interface adopts proxy-mobile IP (PMIP, Proxy Mobile IP) agreement to carry out information interaction.The non-3GPP access of non-credit needs to be connected with P-GW through the packet data gateway (ePDG, Evolved Packet Data Gateway) of evolution, and the interface between ePDG and P-GW is S2b.S2c interface provides subscriber equipment (UE, User Equipment) the user's face and between P-GW is controlled and mobility support, the mobility protocol of its support is for supporting the mobile IP v 6 (DSMIPv6, Mobile IPv6 support for Dual Stack Hosts and Routers) of two stacks.
The fast development of intelligent terminal and mobile Internet application, increases sharply Mobile data flow with speed difficult to the appraisal.In order effectively to alleviate flow pressure, the lasting development that promotes mobile communication business, WLAN (wireless local area network) (WLAN selects to greatly develop in the increasing operator in the whole world, and to adopt WLAN low-cost, high bandwidth be Cellular Networks shunting Wireless Local Area Network).
Access network discovery and selection function (ANDSF, Access Network Discovery and Selection Function) as access anchor point, can realize Intelligent network-selecting, mutual by network and terminal, realize effective shunting of network insertion, the operator that meets following multi-network cooperative to.ANDSF can generate strategy, and helps terminal to select the network formats of best access, realizes the collaborative of plurality of access modes.
In prior art, ANDSF proposes at version (Release-8).When UE will select network to register, if there is 3GPP Access Network and non-3 GPP access network simultaneously, EPS can be current according to UE positional information, by ANDSF, to UE, provide mobility strategy (ISMP between available Access Network information or system, Inter-System Mobility Policy), the information that UE is used ANDSF to provide, selects suitable Access Network to register.If there are a plurality of non-3 GPP access networks simultaneously, EPS can be current according to UE positional information, by ANDSF, to UE, provide routing policy between system (ISRP, Inter-System Routing Policy), the information that UE is used ANDSF to provide, selects suitable Access Network to shunt.Fig. 2 is the associated schematic diagram of UE and ANDSF in prior art, and as shown in Figure 2, ANDSF is connected with UE by S14 interface, this interface employing open mobile alliance device management (OMADM, Open Mobile Alliance Device Management) agreement.
In prior art, ANDSF can solve the access network selection problem that 3GPP is switched to non-3GPP, also can solve the shunting routing problem of multi-access terminal, for example, possesses and activates UE (the IFOM capable UE of IP stream migration ability, IP Flow Mobility capable UE), possesses and activates UE (the MAPCON capable UE of multiple access PDN concatenation ability, Multiple Access PDN Connectivity capable UE), possesses and activates UE (the NSWO capable UE of seamed WLAN shunting ability, Non-seamless WLAN offload capable UE) shunting routing problem.
But there are the following problems for prior art:
1, when terminal is under E-UTRAN covers, due to wide covering and the high mobility of E-UTRAN, operator can preferably be retained in PS business on E-UTRAN.And in some specific occasion, even if terminal is still in E-UTRAN and covers Xia， operator and may also can consider service distributing to WLAN, use mode cheaply to reduce the load of E-UTRAN.But according to existing ANDSF mechanism, ISMP can only be accurate to access technology (AT, Access Technology), so can only realize the access network selection that 3GPP is switched to non-3GPP.And according to existing ANDSF mechanism, ISRP also can only be accurate to AT, so in the time of also can only realizing multithread Route Selection, part stream is wherein selected a kind of access technology.This switching or be diverted to the demand of concrete wireless access type (RAT, Radio Access Type), cannot realize according to prior art.
When 2, terminal resides in E-UTRAN, there is circuit domain (CS, Circuit Switch) movement rises and exhales/Mobile Terminated Call (MO/MT, Mobile Originating/Mobile Terminating) during business, UE is first at MME initiating business request, according to the network capabilities of GERAN or UTRAN, trigger and PS business is switched or suspended to GERAN or UTRAN, then UE forwards GERAN or UTRAN initiation CS business again to.The GERAN disposing at present or UTRAN network scarcely support the two of CS business and PS business to receive two.That is to say, when carrying out CS business, PS business will be suspended, and so just cause the interruption in PS business.Even if GERAN or UTRAN network can support the two of CS business and PS business to receive two, when carrying out CS business, PS business can be switched to GEARN or UTRAN, but the PS speed that can provide due to GEARN or UTRAN is lower, causes some business cannot move and interrupt.This will cause user's business experience very bad.
3, in some specific occasion, due to PS handoff failure, may cause service fail, now can consider to be switched to WLAN.But according to prior art, MME can only know that the objective network of switching is E-UTRAN, UTRAN or the GEARN of 3GPP access technology, does not have a kind of mechanism can indicate MME to remove to find WLAN, thereby cannot realize and be switched to WLAN at present.
4, for the terminal of supporting IP stream migration, operator may wish speech business to remain on UTRAN or the GEARN of 3GPP access technology, video is remained on to the E-UTRAN of 3GPP access technology, by Internet service distributing to WLAN, IFOM capable UE supports to use QoS convection current to identify, the QoS here, i.e. differentiated services code points (DSCP, Differential Service Code Point), codomain scope 0～63.But, according to existing ANDSF mechanism, cannot shunt according to DSCP preferred access network.
5, for the terminal of supporting that IP stream migration or multiple access PDN connect, operator may wish that the business that is connected to internet can be switched to WLAN, and the business that is connected to enterprise network can be switched to the UTRAN of 3GPP access technology.Some multiple access UE supports to use APN convection current to identify, and still, according to existing ANDSF mechanism, cannot shunt according to APN preferred access network.
