Description
Technical field
The present invention relates to moving communicating field, relate in particular to subscriber equipment under a kind of roaming scence (UE) and handle the method and system of two access network discoveries and selection function (ANDSF, Access Network Discovery and SelectionFunction) entity policy conflict.
Background technology
Third generation partner program (3GPP, 3rd Generation Partnership Project) grouping system (EPS of evolution, Evolved Packet System), universal mobile telecommunications system land radio access web (E-UTRAN by evolution, Evolved Universal Terrestrial Radio Access Network), mobile management unit (MME, Mobility Management Entity), gateway (S-GW, ServingGateway), grouped data network gateway (P-GW, Packet Data Network Gateway), home subscriber server (HSS, Home Subscriber Server), strategy and charging rule functions (PCRF, Policy and Charging Rules Function) entity and other support nodes are formed.Wherein, grouped data network gateway also can abbreviate PDN GW as.
The EPS system supports the intercommunication with non-3 GPP system, wherein, passes through the S2a/S2b/S2c interface with the intercommunication of non-3 GPP system and realizes that the anchor point between 3GPP and non-3 GPP system is P-GW.Non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP inserts.The non-3GPP IP of trusted inserts and can directly be connected with P-GW by the S2a interface; Trustless non-3GPP IP inserts the packet data gateway (ePDG, Evolved Packet Data Gateway) that needs through evolution and links to each other with P-GW.Interface between ePDG and P-GW is S2b; S2c provides UE and user's face relevant control and mobility support between the P-GW, and the mobility management protocol of its support is for supporting the mobile IP v 6 (DSMIPv6, Moblie IPv6 Support for Dual Stack Hosts and Routers) of two stacks.
In the EPS system, MME is responsible for the related work of chains of command such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (PDN, Packet Data Network), and the access of being responsible for PDN reaches functions such as transmitting data between EPS and PDN; The PCRF entity is by Rx interface and carrier network agreement (IP, Internet Protocol) business network links to each other, obtain business information, in addition, the PCRF entity also links to each other with gateway device in the network by the Gx/Gxa/Gxc interface, is responsible for initiating the foundation of IP carrying, the service quality (QoS of assurance business datum, and the control of chargeing Quality of Service).
The ANDSF entity is to propose in the EPS of Rel-8 system.As UE the time in home network or in home network of equal value registration, if have 3GPP and non-3 GPP access network simultaneously or have a plurality of non-3 GPP access networks simultaneously, EPS can offer the Access Network information that its current position of UE can be used by the ANDSF entity, so that UE can select suitable Access Network according to s own situation.The ANDSF entity comprises the function of two aspects: data management and controlled function can provide network to find and the selection auxiliary data according to carrier policy.The ANDSF entity mainly provides two kinds of information, shift strategy and access network discovery information between system.Shift strategy is can be graduate between system, the strategies of using such as: hard-core general strategy or according to the active state of UE etc., wherein the strategy of using according to the active state of UE can activate the Different Strategies that (active) and idle (idle) state are stipulated down for UE.If access network discovery information spinner: access network type, such as wireless lan (wlan) or micro-wave access global inter communication (WiMAX); The Access Network sign is such as the service set identifiers among the WLAN (SSID, ServiceSet Identifier); The public land mobile network that can insert (PLMN) information; The priority of access network etc.Certainly the ANDSF entity also can be based on the current position of UE, and limit information such as capacity offer the quantity of UE information.According to the demand of operator, the ANDSF entity can also provide two kinds of information simultaneously or wherein a kind of information only is provided.
Be illustrated in figure 1 as the configuration diagram that relates to the ANDSF entity.The ANDSF entity directly links to each other with UE by the S14 interface, and the S14 interface uses OMA DM agreement.The S14 interface is supported PULL and PUSH pattern, and wherein, the PULL pattern mainly is: UE triggers the ANDSF entity sends pattern from the network information to UE after network carries out the active application; And the PUSH pattern mainly is: initiatively triggered the pattern that sends data to UE by network.Wherein, OMA DM agreement is Open Mobile Alliance (OMA, Open MobileAlliance) cover of tissue definition is specifically designed to the management agreement that moves with wireless network, is the branch of OMA, and OMA DM agreement is mainly used to the various device terminal is managed.
Be illustrated in figure 2 as the workflow schematic diagram that uses the ANDSF entity, this flow process may further comprise the steps:
Step 101, UE are linked into P-GW by 3GPP Access Network or non-3 GPP access network.
Step 102, UE find the ANDSF entity.
Here, step 102 is optional steps, is represented by dotted lines among the figure.
Step 103, UE send the access network message request to the ANDSF entity,
Here, carry UE ability information or UE positional information in this request.
The positional information that step 104, ANDSF entity report according to UE will return to UE at the access network message response of above-mentioned access network message request.
Here, carry access network information that the UE current location can use and up-to-date system's shift strategy in this response.
Step 105, UE carry out network selecting and switch decision.
Step 106, UE are switched according between self needs initiation system.
Be illustrated in figure 3 as the configuration diagram that relates to the ANDSF entity under the roaming scence.Among Fig. 3, UE links to each other with the VANDSF entity with the HANDSF entity respectively by two S14 interfaces.Here, HANDSF entity aim belongs to the ANDSF entity of network; The VANDSF entity refers to the ANDSF entity of visited network.The HANDSF entity sends the relevant access network policy of roaming UE to UE; The VANDSF entity sends the relevant access network policy on visit ground to UE.
Because the access network policy of UE is provided by HANDSF entity and VANDSF entity respectively, therefore, the access network policy that HANDSF entity and VANDSF entity provide is likely conflict.Such as: the access network policy that the HANDSF entity provides is: WLAN/SSID=v, Priority=1; WLAN/SSID=z, Priority=2; And the access network policy that the VANDSF entity provides is: WLAN/SSID=z, Priority=1; WLAN/SSID=v, Priority=2.And the access network policy that UE handles these two kinds of conflicts has two principles: one, the power to make decision of wireless access technology (RAT, Radio AccessTechnology) selection is at visited network; Two, under roaming scence, home network can be expressed the hobby of its network priority, and promptly the power to make decision of access network selection is at home network.Because the policy conflict that UE receives can cause UE access network in time, perhaps the network that is inserted is not preferred, thereby have influence on the sense of experience of users of using UE, therefore, press for the solution of a kind of HANDSF of processing entity and VANDSF entity policy conflict at present.
