Abstract

The invention relates to the wireless communication field, and discloses a method for establishing wireless network default carry and a system thereof, which ensure that the process for establishing the wireless network default carry is accelerated, and individual services are flexibly provided to a user. In the invention, one of various default PCC rules which are preconfigured is selected in a UE attachment process, and the default carry for the UE is established by PCEF according to the default PCC rules. A network side classifies the default carry in advance, and each default carry is corresponding to a default PCC rule. The network side can classify the default carry in advance according to modes such as charging standard, business model, service model, signed user level and so on. If the selected default PCC rule is preconfigured in the PCEF or is sent to the PCEF, a network entity selecting the default PCC rule only sends an identification number of the rule without sending the content of the rule to the PCEF.

Description

Default bearing establishing method for wireless network and system thereof

Technical field

The present invention relates to wireless communication field, particularly default bearer is set up technology.

Background technology

Universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short " UMTS ") be third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") 3-G (Generation Three mobile communication system) of the employing Wideband Code Division Multiple Access (WCDMA) that proposes (Wideband Code Division MultipleAccess is called for short " WCDMA ") air interface technologies.In the UMTS network, be just to carry when business is arranged for this UE sets up accordingly at subscriber equipment (User Equipment is called for short " UE "), loading establishing process is initiated by UE.

Yet, progressively development along with communication, people are more and more high for the requirement of mobile communication, therefore, 3GPP has proposed a kind of notion of serving the evolvement network of future communications demand, System Architecture Evolution (System Architecture Evolution is called for short " SAE ") just belongs to the wireless core network evolution items of future generation that 3GPP proposes.

The SAE of regulation mainly comprises among the TR23.882-V1 80: mobile management entity (MobilityManagement Entity, abbreviation " MME "), user entity (User Plane Entity, be called for short " UPE "), 3GPP Anchor (3GPP anchor point) and four logic function modules of SAE Anchor (SAE anchor point), as shown in figure 16.MME wherein is the mobile management module, is responsible for the mobile management of chain of command, and it is corresponding to the current UMTS internal system GPRS serving GPRS support node control plane part of (Serving GPRS Support Node is called for short " SGSN "); UPE is a user entity, triggers MME when being responsible for the downlink data arrival is arranged under the idle condition and initiates paging, and IP bearing parameter and the interior routing iinformation of network etc. are preserved in management, and it is corresponding to the datum plane part of current UMTS internal system SGSN; The 3GPP anchor point is the user's face anchor point between different access systems in the 3GPP system; The SAE anchor point is the user's face anchor point between 3GPP connecting system and non-3 GPP system among the SAE.SAE anchor point and 3GPP anchor point are collectively referred to as anchor point between connecting system (Inter AS Anchor is called for short " IASA ").The non-roaming framework of evolvement network as shown in figure 16 among the TR23.882, the roaming framework of evolvement network is respectively shown in Figure 17 and 18 among the TR23.882, Figure 17 is for going out the roaming framework schematic diagram of SGi interface (Home Routed) from home network, Figure 18 is for directly going out the roaming framework schematic diagram of SGi interface (Local Breakout) from roaming network.

In the SAE network, for increasing to the support of speech business and the speed that continues of raising portable terminal, when UE is attached to network (UE for the service start-up logging that obtains network and provide to network), will set up carrying with network is connected, to realize " always online " function of user, so that the user can initiate business fast, this carries to connect just to be called and is default bearer.Flow process when UE is attached to network wherein comprises the process that default bearer is set up as shown in Figure 1.

In step 101, UE sends to MME and adheres to request, can carry the sign of UE in this message and (preferentially use temporary mark: packet TMSI (Packet Temporary MobileSubscriber Identity, be called for short " P-TMSI "), use permanent identification in the absence of P-TMSI: IMSI International Mobile Subscriber Identity (International Mobile Subscriber Identity, be called for short " IMSI ")), core net is by this sign identification UE and finish authentication and the UE attaching process, simultaneously, also can carry Access Point Name (Access Point Name is called for short " APN ") etc. in this message.

Then, in step 102, MME judges whether it has the available authentication vector of this UE, as there not being the bi-directional authentification process (be illustrated as dotted line, represent that this process is optional) that then triggers between this UE and the network.

Then, to step 106, MME initiates the position to home subscriber server (HomeSubscriber Server is called for short " HSS ") and upgrades, and registers the serving MME of current MME entity for this UE to HSS, and the request user contracting data in step 103.HSS inserts user contracting data in MME.MME returns to HSS and inserts the user contracting data success.HSS upgrades acknowledge message to the MME home position.

Then, to step 110, MME sends to UPE and creates bearing request message, carries APN and user's face key (UP key) etc. in step 107.UPE selects IASA according to APN, and sets up request message to selected IASA transmission routing update/carrying.IASA and "Policy and Charging Rules Function (Policy and Charging Rules Function, abbreviation " PCRF ") carries out Signalling exchange, to determine the strategy that default bearer uses and control (the Policy and Charging Control that charges, be called for short " PCC ") rule, strategy and charge execution function in this flow process (Policy and Charging EnforcementFunction is called for short " PCEF ") are positioned on the IASA.IASA sends routing update response/bearing response message to UPE, and UPE sends bearing response message to MME.

Then, to step 113, MME sends radio bearer to eNB (evolution base station node) and sets up request message in step 111.Setting up Radio Resource control (Radio ResourceControl is called for short " RRC ") signaling between eNB and UE connects.ENB sends the radio bearer response message to MME., therefore be represented by dotted lines actually, do not determine as yet at present because or radio bearer is created when adhering to and just set up when transfer of data is arranged.

Then, in step 114, MME sends the carrying acknowledge message to UPE.In step 115 and step 116, MME sends to adhere to UE and accepts message.UE sends to adhere to MME and finishes message.

Below the PCC that relates in the above-mentioned flow process is introduced.PCC is a kind of unified control and charging policy framework, as shown in Figure 2.Be applicable to various IP-CAN (IP connects Access Network) at this framework.In this framework, application function (Application Function is called for short " AF ") provides required relevant parameter to PCRF, and the effect of PCRF is according to these parameters generation PCC rules and sends it on the PCEF that the effect of PCEF is to carry out the PCC rule.The PCC rule can be divided into dynamic generation and pre-configured two kinds: dynamically the PCC rule that generates is dynamically generated by PCRF and sends among the PCEF by the Gx interface, is activated by PCRF; Pre-configured PCC rule directly is pre-configured to be among the PCEF, can activate according to carrier policy by PCRF or by PCEF.For different IP-CAN, PCEF is arranged in its corresponding gateway (GW).

Insert for 3GPP, the evolvement network that writes among the TS23.401-V030 is shown in Figure 19～21.Wherein, Fig. 19 and 20 is non-roaming network architecture, in Figure 20, may have S5 interface shown in Figure 19 between service SAE gateway of putting together and Packet Data Network (Packet Data Network is called for short " PDN ") the SAE gateway; Figure 21 is the PLMN that is respectively home network (PublicLand Mobile Network is called for short " PLMN ") on boundary and the PLMN of roaming network with the heavy line for go out the evolvement network roaming framework schematic diagram of SGi interface from home network.In addition, the roaming framework that comprises PCC is determined as yet, so whether the S9 interface between H-PCRF (ownership PCRF) and the V-PCRF (PCRF of roaming network) exists definite as yet at present.

Insert for non-3GPP (non-3GPP), the evolvement network that writes among the TS23.402-V030 is shown in Figure 22,23.Wherein, Figure 22 is non-roaming network architecture; Figure 23 goes out the evolvement network roaming framework schematic diagram of SGi interface from home network.

Among Fig. 1 9～23, service SAE gateway is equivalent to UPE and the 3GPP anchor point among the TR23.882, and PDN SAE gateway is equivalent to the SAE anchor point.

The present inventor finds, if when a UE is attached to network, network side all needs for this UE generates the PCC rule that is used to set up default bearer, in the processing time in the time of then can increasing to this UE to a certain extent and set up default bearer, initiates professional rapidity thereby influenced UE.And, because the type of service of the network operation is limited,, will increase unnecessary complexity for system if for each UE sets up the default bearer that the PCC rule has nothing in common with each other.

Summary of the invention

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.

In the embodiments of the present invention, network side is classified to default bearer in advance, be divided into N class default bearer (N 〉=1), corresponding one of every class default bearer pre-configured is set up the PCC rule of using in the process at default bearer, and the present invention abbreviates it as " default PCC rule ".Except that the IM CN subsystem signaling, the business that operates in the network scarcely is to ensure bit rate (Guaranteed BitRate, abbreviation " GBR ") business of business and operator control, and PCRF does not have too many control ability to these business, therefore, need not the dynamic PCC rule that generates in PCRF, can adopt pre-configured default PCC rule.That is to say, the default bearer of UE is divided into the N class, also can think different UE is divided into N classification, the corresponding pre-configured default PCC rule of different classes of UE is enjoyed different classes of service.

If for each UE sets up the default bearer that the PCC rule has nothing in common with each other, that is to say, N equals the UE number, can make system become comparatively complicated; If all UE use the identical default bearer of PCC rule, promptly N equals 1, and is then friendly inadequately and lack flexibility to the user, because each user may customize different business as required, thereby pays different expenses, enjoy the service of different stage.Therefore, the preferred value of N is 1 between the UE number, so that in not malfunctioning activity, and for the UE of different stage provides corresponding personalized service, the quantity of the default PCC rule that can also effectively reduce on the network side to be stored.And, guaranteed that the number of pre-configured default PCC rule is limited, the processing procedure when further having accelerated to set up default bearer for UE.

The classification foundation of UE default bearer has multiple, such as, can carry out according to carrier policy, concrete sorting technique has following several mode:

(1) in advance default bearer is classified according to expenses standard, high rate person enjoys high level service;

(2) in advance default bearer is classified according to business prototype or business model, such as, customization which set meal;

(3) in advance default bearer is classified according to signatory user class, such as according to customer consumption accumulation amount or service time length the user is divided into domestic consumer, gold user, platinum user etc.

UE for roaming, can adopt predetermined mapped mechanism to obtain the pre-configured default PCC rule of this UE in the pairing pre-configured default PCC rule of the default bearer classification of ownership place according to this UE, thereby determine the default bearer classification of this UE at roaming network in the roaming place; Perhaps, can obtain the default PCC rule of this UE, thereby determine the default bearer classification of this UE at roaming network according to the roaming agreement between roaming network and the home network in the roaming place; Perhaps, can also obtain the default PCC rule of this UE, thereby determine the default bearer classification of this UE at roaming network by the roaming network carrier policy in the roaming place.

But in the progress of standard afterwards, insert for 3GPP, the PCEF function may move down into service SAE gateway even Access Network side in addition, insert for non-3GPP, the PCEF function also might be positioned at packet data gateway (the evolved Packet Data Gateway of evolution, be called for short " ePDG "), be that example describes but the embodiments of the present invention all are arranged in PDN SAE gateway with the PCEF function.

First execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, the pairing default PCC rule of different classes of UE or its identification number are kept in the Universal Database as the subscription data of this UE, as HSS, signatory Specifications Database (Subscription ProfileRepository, be called for short " SPR ") or AAA server (AuthenticationAuthorization and Accounting Server, be called for short " AAA ") etc., network side is selected default PCC rule according to the subscription data of UE.Present embodiment is HSS with the Universal Database, and each default PCC rule is pre-configured to be among the PCEF to example describes, and idiographic flow as shown in Figure 3.

In step 301, UE sends to MME and adheres to request, can carry the sign (preferentially use temporary mark P-TMSI, use permanent identification IMSI in the absence of P-TMSI) of UE in this message, core net is by this sign identification UE and finish authentication and the UE attaching process.

Then, enter step 302, MME judges whether it has the available authentication vector of this UE, as there not being the bi-directional authentification process (be illustrated as dotted line, represent that this process is optional) that then triggers between UE and the network.

Then, enter step 303, MME initiates the position to HSS and upgrades, and registers the serving MME of current MME entity for this UE to HSS, and the request user contracting data.

Then, enter step 304, HSS provides user contracting data to MME.Because the identification number of the different classes of pairing default PCC rule of UE is kept among the HSS as the subscription data of this UE, therefore, HSS provides the identification number (ID) of the default PCC rule that comprises this UE in the user contracting data to MME.That is to say that MME can inquire the identification number of the default PCC rule of this UE.Because present embodiment has adopted the mode of piggyback, so step 303 and step 304 realized that the position is upgraded and request user contracting data function, promptly is equal to step 103 among Fig. 1 to step 106.

Then, enter step 305, MME sends to service SAE gateway and creates bearing request message, carries the identification number of the default PCC rule of this UE that inquires in this message.

Then, enter step 306, service SAE gateway sends routing update/bearing request message to PDN SAE gateway, carries the identification number of the default PCC rule of this UE that inquires in this message.Because each default PCC rule is pre-configured to be in the PCEF in the PDN SAE gateway, therefore, PCEF in the PDN SAE gateway can according to this identification number for this UE activates corresponding PCC rule, and set up wired carrying between service SAE gateway and the PDN SAE gateway in this step.Owing to do not need to send Rule content, as long as send out the sign of rule, reduced the traffic between the heterogeneous networks entity, thereby saved system resource, and accelerated the process of setting up of carrying to PCEF.

Then, enter step 307, PDN SAE gateway sends routing update response and carrying response to service SAE gateway.

Then, enter step 308, service SAE gateway sends bearing response message to MME.

Then, enter step 309, MME sends radio bearer to eNB and sets up request message.

Then, enter step 310, between eNB and UE, set up radio bearer.

Then, enter step 311, eNB sends the radio bearer response message to MME.

Then, enter step 312, MME sends the carrying acknowledge message to service SAE gateway.

Then, enter step 313, MME sends to adhere to UE and accepts message.

Then, enter step 314, distributed new P-TMSI if core net is UE, then UE sends to adhere to MME and finishes message.

Be not difficult to find, in the present embodiment, owing to carried out pre-configured to default PCC rule, therefore do not need to generate a rule for each UE, when setting up default bearer,, thereby make that the workload of handling is less relatively as long as from limited several rules that configured, select one for UE, processing procedure is very fast relatively, has reduced the setup delay of default bearer.

Second execution mode of the present invention relates to default bearing establishing method for wireless network, the present embodiment and first execution mode are roughly the same, its difference is, in the first embodiment, each default PCC rule is pre-configured to be among the PCEF, and in the present embodiment, each default PCC rule is pre-configured to be among the HSS.

Specifically, PCEF in the PDN SAE gateway need preserve paid-in default PCC rule, HSS is by carrying out record to the default PCC rule that sends to this PCEF, whether the default PCC rule of judging the current UE that adheres to has sent to this PCEF, if, then the identification number with the default PCC rule of this UE sends to this PCEF, and this PCEF activates corresponding PCC rule according to this identification number, for this UE sets up default bearer (identical with the flow process of first execution mode).If the default PCC rule of this UE does not send to this PCEF as yet, then the default PCC rule with this UE sends to this PCEF, this PCEF sets up default bearer according to the default PCC rule of receiving for this UE, in this case, in step 304, HSS provides in the user contracting data to MME, the default PCC rule that need comprise this UE, but not the identification number of default PCC rule, in step 305 and step 306, the establishment bearing request message that MME sends to service SAE gateway, and service SAE gateway is in routing update/bearing request message that the PDNSAE gateway sends, the default PCC rule that need comprise this UE, but not the identification number of default PCC rule.

Though in the present embodiment, default PCC rule is not pre-configured to be among the PCEF, but because PCEF preserves paid-in default PCC rule, therefore, if sent to this PCEF before the default PCC rule of the current UE that adheres to, then do not need repetition to send Rule content yet, reduced the traffic between the heterogeneous networks entity, thereby saved system resource to PCEF.

What deserves to be mentioned is, be to be that HSS is that example describes with the Universal Database in first, second execution mode, if Universal Database is an aaa server, then this aaa server sends to PCEF with the default PCC rule of UE correspondence or its identification number of this default PCC rule, it is identical with first, second execution mode respectively with two kinds of situations in the aaa server to be pre-configured to be in PCEF for each default PCC rule, does not repeat them here.If Universal Database is SPR, then this SPR sends to PCEF by the PCRF of network side with the default PCC rule of UE correspondence or the identification number of this default PCC rule, it is identical with first, second execution mode respectively with two kinds of situations in the aaa server to be pre-configured to be in PCEF for each default PCC rule, does not repeat them here.

The 3rd execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, each default PCC rule is pre-configured to be among the PCEF, determine the identification number of default PCC rule by the PCRF of network side, PCEF sets up default bearer according to the selected default PCC rule of this PCRF for this UE.Idiographic flow as shown in Figure 4.

In step 401, UE sends to MME and adheres to request, can carry the sign (preferentially use temporary mark P-TMSI, use permanent identification IMSI in the absence of P-TMSI) of UE in this message, core net is by this sign identification UE and finish authentication and the UE attaching process.

Then, enter step 402, MME judges whether it has the available authentication vector of this UE, as there not being the bi-directional authentification process (be illustrated as dotted line, represent that this process is optional) that then triggers between UE and the network.

Then, enter step 403 and step 404, MME initiates the position to HSS and upgrades, and registers the serving MME of current MME entity for this UE to HSS, and the request user contracting data.HSS provides user contracting data to MME.

Then, enter step 405, MME sends to service SAE gateway and creates bearing request message.

Then, enter step 406, service SAE gateway sends routing update/bearing request message to PDN SAE gateway.

Then, enter step 407, carry out Signalling exchange between PDN SAE gateway and the PCRF, PCRF select the default PCC rule of this UE, and the identification number of the default PCC rule that will select returns to PDN SAE gateway according to certain strategy; Perhaps, the identification number of PDN SAE gateway default PCC rule of this UE of inquiry in the SPR, and the identification number of the default PCC rule that will inquire returns to PDN SAE gateway.

Because each default PCC rule is pre-configured to be in the PCEF in the PDN SAE gateway, therefore, PCEF in the PDNSAE gateway can according to this identification number for this UE activates corresponding PCC rule, and set up wired carrying between service SAE gateway and the PDN SAE gateway in this step.This shows that PCRF does not need to send Rule content to PCEF, as long as send out the sign of rule, has reduced the traffic between the heterogeneous networks entity, thereby has saved system resource.

Need to prove, mutual information between PCEF and PCRF may comprise following parameter: MME ID (MME identification number), service SAE gateway identification number, PDN SAE gateway identification number, UE identification number, positional information (location information), charge information (charging information), CAMEL-Subscription-Information etc., these parameters may come together to determine the default PCC rule of this UE with the strategy of user's CAMEL-Subscription-Information and operator.If PCRF can obtain the CAMEL-Subscription-Information of this UE by reporting of UE, then PCRF need not by with the CAMEL-Subscription-Information that obtains this UE alternately of SPR.

Step 408 is identical to step 314 with step 307 respectively to step 415, does not repeat them here.

The 4th execution mode of the present invention relates to default bearing establishing method for wireless network, present embodiment and the 3rd execution mode are roughly the same, its difference is, in the 3rd execution mode, each default PCC rule is pre-configured to be among the PCEF, and in the present embodiment, each default PCC rule is pre-configured to be among the PCRF.

Specifically, PCRF is by carrying out record to the default PCC rule that sends to this PCEF, whether the default PCC rule of judging current selection has sent to this PCEF, if, the identification number of the default PCC rule that then will select sends to this PCEF, this PCEF activates corresponding PCC rule according to this identification number, for this UE sets up default bearer (identical with the flow process of the 3rd execution mode).If the default PCC rule of selecting does not send to this PCEF as yet, the default PCC rule that then will select sends to this PCEF, this PCEF sets up default bearer according to the default PCC rule of receiving for this UE, in this case, in step 407, what PCRF returned to PDN SAE gateway is the default PCC rule of selecting, but not the identification number of the default PCC rule of selecting.PCEF in the PDN SAE gateway need preserve paid-in default PCC rule.

This shows,, then also do not need repetition to send Rule content, reduced the traffic between the heterogeneous networks entity, thereby saved system resource to PCEF if sent to this PCEF before the default PCC rule of current selection.

What deserves to be mentioned is, in third and fourth execution mode, if the parameter with default PCC rule is a default parameters, then PCRF can also change the partial parameters of selected default PCC rule according to the CAMEL-Subscription-Information of carrier policy and this UE, therefore, in step 407, PCRF also needs to return the PCC parameter that those need change to PDN SAE gateway.

The 5th execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, network side is according to service quality (the Quality of Service of UE, be called for short " QoS ") parameter, as label Label, MBR or AMBR etc., select default PCC rule, PCEF sets up default bearer according to selected default PCC rule for this UE, and the network entity of selecting default PCC rule can be HSS, SPR, MME, PCEF or PCRF.In the present embodiment to select default PCC rule (Label is kept among the HSS as subscription data) according to Label, the network entity of selecting default PCC rule is that PCEF is that example describes, each default PCC rule is pre-configured to be in the PCEF, and idiographic flow as shown in Figure 5.

Step 501 is identical to step 303 with step 301 respectively to step 503, does not repeat them here.

In step 504, HSS provides user contracting data to MME, and the Label that UE contracts is provided in the user contracting data that provides.

Then, in step 505, MME sends to service SAE gateway and creates bearing request message, carries Label in this message.

Then, in step 506, service SAE gateway sends routing update/bearing request message to PDN SAE gateway, carries Label in this message.PCEF in the PDN SAE gateway activates corresponding PCC rule, and sets up the wired carrying between service SAE gateway and the PDN SAE gateway in this step according to the default PCC rule that this Label selects UE.Because Label is a qos parameter, therefore, selects default PCC rule according to Label, can be so that different classes of UE enjoys different service quality

Step 507 is identical to step 314 with step 307 respectively to step 514, does not repeat them here.

The 6th execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, network side is according to the qos parameter of UE, as label Label, MBR or AMBR etc., select default PCC rule, PCEF sets up default bearer according to selected default PCC rule for this UE, and the network entity of selecting default PCC rule can be HSS, SPR, MME, PCEF or PCRF.To select default PCC rule (Label is provided by PCRF) according to Label, the network entity of selecting default PCC rule is that PCEF is that example describes in the present embodiment, and each default PCC rule is pre-configured to be in the PCEF, and idiographic flow as shown in Figure 6.

Step 601 is identical to step 406 with step 401 respectively to step 606, does not repeat them here.

In step 607, carry out Signalling exchange between PDN SAE gateway and the PCRF, the Label of PCRF decision UE also returns to PDN SAE gateway, PCEF in the PDN SAE gateway selects the identification number of the default PCC rule of UE in view of the above, activate corresponding PCC rule, and in this step, set up the wired carrying between PDN SAE gateway and the service SAE gateway.Because Label is a qos parameter, therefore, selects default PCC rule according to Label, can be so that different classes of UE enjoys different service quality.

Step 608 is identical to step 415 with step 408 respectively to step 615, does not repeat them here.

The 7th execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, UE is in attaching process, the identification number of default PCC rule of expectation is sent to network side, network side is selected corresponding default PCC rule according to the identification number of receiving, and each default PCC rule is pre-configured to be among the PCEF.Idiographic flow as shown in Figure 7.

In step 701, UE sends to MME and adheres to request, can carry the sign (preferentially use temporary mark P-TMSI, use permanent identification IMSI in the absence of P-TMSI) of this UE in this message, core net is by this sign identification UE and finish authentication and the UE attaching process.Simultaneously, also will carry the identification number of the default PCC rule of this UE expectation in this message.

The 12 execution mode of the present invention relates to default bearing establishing method for wireless network, the difference of present embodiment and the respective embodiments described above is, the respective embodiments described above are applied to the scene that UE is linked into the 3GPP network, and present embodiment is applied to the scene that UE is linked into non-3GPP network.In the present embodiment, adopt the proxy-mobile IP mobility management protocol of (Proxy Mobile IP is called for short " PMIP ") in the non-3GPP network, idiographic flow as shown in figure 13.

In step 1301, as UE during in non-3GPP network attachment, UE will initiate the Internet IKE version 2 tunnel establishment procedure of (Internet Key Exchange Protocol Version 2 is called for short " IKEv2 ").The address of the packet data gateway of evolution (evolved Packet DataGateway, be called for short " ePDG ") can be pre-configured or by DNS (DOMAINNAME SYSTEM is called for short " DNS ") inquiry, UE is by authentication subsequently.

In the IKE tunnel establishment procedure, the address of PDN SAE gateway can be sent to ePDG.The mode of obtaining the address of PDN SAE gateway can be notified to ePDG by HSS/AAA when access authentication or service authentication, also can report this address voluntarily when adhering to by UE, but does not also limit to these modes.The address of PDNSAE gateway also can be kept in the source network side network entity and (as MME, HSS), in switching set-up procedure, give ePDG or UE with the address notification of PDN SAE gateway.For example the interface by MME and ePDG is notified to ePDG; For example in switching preparation, be notified to UE, or in the SAE of UE network attachment process, directly be notified to UE.In this step, UE can obtain the address of ePDG in the following ways:

(1) in access authentication process, the parameter (as APN, network address sign NAI) of UE by reporting by the address that HSS/AAA determines ePDG, PDN SAE gateway, notified UE in the response message of access authentication;

Need to prove, when there being a plurality of home agent (Home Agent, be called for short " HA ") time, be similar to the situation of many PDN SAE gateway, different HA handle different business, at this moment, and after UE inserts non-3GPP network, UE can initiate service request to new PDN SAE gateway (that is: HA), and HSS/AAA can determine new ePDG, the address of PDN-GW by some parameters (as: APN, network address sign NAI).These parameters can be carried in the PMIP login request message, but are not limited to this form.

(2) behind access authentication, obtain the address of ePDG, PDN SAE gateway by the DNS query script;

(3) in switching set-up procedure, (, HSS) notify the ePDG of UE access network, the address of PDN SAE gateway as MME by the source network side entity.

Then, in step 1302, ePDG sends agent binding message to PDN SAE gateway, and this PDN SAE gateway is handled this agent binding message of receiving.

Specifically, this PDN SAE gateway need be set up the entity of binding for this UE, and this UE is given in the distributing IP address.If PDN SAE gateway need carry out safety certification to this binding message, then this PDN SAE gateway will be got in touch aaa server and be verified authentication and key information (this safety certification is an optional step) in the binding message.In addition, this PDN SAE gateway also needs to be pre-configured default PCC rule of the UE of this access selection according to strategy and subscription data.

Such as, each default PCC rule is pre-configured to be in the PCEF in the PDN SAE gateway, this PCEF indexes relevant PCC rule according to the parameter in the agent binding message of receiving, that is to say, according to the parameter of carrying in this agent binding message, select one from pre-configured each the default PCC rule of network side, the parameter in the agent binding message can be reported by UE, or obtains from network side entity in authentication process.The index PCC rule that can show by the identification number that carries default PCC rule explicit in agent binding message (as being notified to UE in step 1301 during authentication), also can utilize other parameter (as APN, multiple parameters such as network address sign NAI, or the combination of multiple parameter) come the relevant PCC rule of index, the PCC rule that indexes promptly is the default PCC rule of selecting for this UE.This PCEF activates the default PCC rule that indexes, and sets up default bearer according to this default PCC rule for this UE.

Perhaps, report to PCRF by the PCEF in the PDN SAE gateway and to set up bind request, and send to PCEF by the default PCC rule that PCRF will be correlated with.Specifically, PCEF reports to PCRF and to set up the user and request in person and ask after receiving agent binding message, comprises the NAI that is used for identifying user in this request message, Access RAT parameters such as (access wireless technologys), and the default PCC rule of asking this UE.This PCRF is after the request of receiving from PCEF, to get in touch SPR and (in the present embodiment SPR and HSS will be divided into two logic entities, but also might in same physical entity, realize), to SPR request relevant information, as the identification number of the subscription data of this UE, PCC rule or PCC rule etc.PCRF is according to the information that gets access to from SPR, as the identification number of the subscription data of this UE, PCC rule or PCC rule etc., obtains the default PCC rule selected into this UE, and should default PCC rule send to PCEF.This PCEF sets up default bearer according to the selected default PCC rule of this PCRF for this UE.

Or, prewiredly among this PCEF be equipped with each default PCC rule, but need PCRF to activate this default PCC rule to the identification number that this PCEF is sent as the default PCC rule that this UE selects.Specifically, can be divided into two kinds of situations:

A. the identification number of each default PCC rule is pre-configured in SPR, this PCRF by with the identification number of the default PCC rule that gets access to this UE alternately of this SPR;

B. the identification number of each default PCC rule is pre-configured in PCRF, this PCRF may need by and SPR between mutual user signing contract information select the identification number of the default PCC rule of this UE, and the identification number of the default PCC rule that will select sends to this PCEF, this PCEF activates corresponding default PCC rule according to the identification number of receiving, and sets up default bearer according to this rule for this UE.

In this step, PCRF also may pass to PCEF with the QoS Profile of this service needed.Also can be in this step, ePDG carries this professional required QoS profile parameter (for example by the expansion to the PMIP registration message, required QoS profile parameter being passed to PCEF) in the agent binding message that sends.EPDG can also can report this parameter by UE by obtaining the QoSprofile parameter when the access authentication from HSS/AAA when adhering to.

Then, in step 1303, PDN SAE gateway sends agent binding to be confirmed to ePDG, and this agent binding may be included as this UE IP address allocated, qos parameter information in confirming.This PDN SAE gateway may need to carry out alternately with PCRF, with the qos parameter that obtains to be correlated with.

Then, in step 1304, after the agent binding success, IP Sec passage is set up and is finished.

Then, in step 1305, ePDG sends final IKEv2 information to UE, is included as this UE IP address allocated etc. in this information.

Then, in step 1306, set up the connectedness of this UE to the IP of PDN SAE gateway.

The 13 execution mode of the present invention relates to default bearing establishing method for wireless network, present embodiment and the 12 execution mode are roughly the same, its difference is, in the 12 execution mode, adopt the mobility management protocol of PMIP in the non-3GPP network, and in the present embodiment, adopt client mobile IP (Client Mobile IP in the non-3GPP network, abbreviation " CMIP ") mobility management protocol of version 6, idiographic flow as shown in figure 14.

In step 1401, as UE during in non-3GPP network attachment, this UE will initiate the tunnel establishment procedure of an IKEv2.The address of ePDG can be pre-configured or inquire about by DNS.UE is by authentication subsequently.

Need to prove, when having a plurality of HA, be similar to the situation of many PDN SAE gateway, different HA handle different business, at this moment, after UE inserted non-3GPP network, UE can initiate service request to new PDNSAE gateway (that is: HA), and HSS/AAA can determine new ePDG, the address of PDN-GW by some parameters (as: APN, network address sign NAI).These parameters can be carried in the MIP login request message, but are not limited to this form.

Then, in step 1402, ePDG sends final IKEv2 information to UE, is included as this UE IP address allocated etc. in this information.

Then, in step 1403, set up the IP sec passage between this UE and this ePDG.

Then, in step 1404, the security association between this UE foundation and the PDN SAE gateway is to guarantee that binding information subsequently is safe.In setting up the process of Security Association, QoS profile parameter that also can this is professional passes to PDN SAE gateway.

Then, in step 1405, this UE sends binding update messages to PDN SAE gateway, and this PDN SAE gateway is handled this binding update messages of receiving.

Such as, each default PCC rule is pre-configured to be in the PCEF in the PDN SAE gateway, this PCEF indexes relevant PCC rule according to the parameter in the binding update messages of receiving, that is to say, according to the parameter of carrying in this binding update messages, from pre-configured each the default PCC rule of network side, select one.The index PCC rule that can show by the identification number that carries default PCC rule explicit in binding update messages (as being notified to UE in step 1401 during authentication), also can utilize other parameter (as APN, multiple parameters such as network address sign NAI, or the combination of multiple parameter) come the relevant PCC rule of index, the PCC rule that indexes promptly is the default PCC rule of selecting for this UE.This PCEF activates the default PCC rule that indexes, and sets up default bearer according to this default PCC rule for this UE.

Perhaps, report to PCRF by the PCEF in the PDN SAE gateway and to set up bind request, and send to PCEF by the default PCC rule that PCRF will be correlated with.

Specifically, PCEF reports to PCRF and to set up the user and request in person and ask after receiving binding update messages, comprises the NAI that is used for identifying user in this request message, Access RAT parameters such as (access wireless technologys), and the default PCC rule of asking this UE.This PCRF is after the request of receiving from PCEF, to get in touch SPR and (in the present embodiment SPR and HSS will be divided into two logic entities, but also might in same physical entity, realize), to SPR request relevant information, as the identification number of the subscription data of this UE, PCC rule or PCC rule etc.PCRF is according to the information that gets access to from SPR, as the identification number of the subscription data of this UE, PCC rule or PCC rule etc., obtains the default PCC rule selected into this UE, and should default PCC rule send to PCEF.This PCEF sets up default bearer according to the selected default PCC rule of this PCRF for this UE.

Or this PCEF is upward prewired to be equipped with each default PCC rule, but needs PCRF to activate this default PCC rule to the identification number that this PCEF is sent as the default PCC rule of this UE selection.Specifically, can be divided into two kinds of situations:

In this step, PCRF also may pass to PCEF with the QoS Profile of this service needed.Also can be in this step, ePDG intercepts and captures the UE registration message, and increases this professional required QoS profile parameter (for example by the expansion to the MIP registration message, required QoS profile parameter being passed to PCEF) in the binding update messages that sends.EPDG can be by obtaining QoS profile parameter when the access authentication from HSS/AAA.UE also can carry this professional qos parameter in binding message, for example by many MIPv4, and MIPv6, the expansion of registration messages such as DS-MIP reports this parameter to give PDN SAE GW;

Then, in step 1406, this UE is given in PDN SAE gateway distributing IP address, and sends binding acknowledgement message and give this UE, sets up the connectedness of UE to the IP of PDN SAE gateway

The 14 execution mode of the present invention relates to default bearing establishing method for wireless network, and present embodiment has increased the situation that UE is in roaming network on the basis of the respective embodiments described above.

Because the default bearer under the roaming scence also should be classified, and the corresponding default PCC rule of every class default bearer.Therefore, if UE is in roaming network, will select default PCC rule for this UE by home network and/or roaming network, PCEF is according to selected default PCC rule, for this UE sets up default bearer.Different as the case may be, for the default PCC rule that this UE selects, may be the default PCC rule of this UE in home network, also may be the default PCC rule of selecting for this UE in roaming network.

Specifically, under the roaming scence, whether whether need has the PCEF function relevant for the default PCC rule that UE is chosen in the roaming network with roaming network, there is the PCEF function then need be chosen in default PCC rule in the roaming network for UE certainly as roaming network, otherwise looking concrete condition determines whether and need generally not need for UE is chosen in default PCC rule in the roaming network.For the situation that does not need to be chosen in for UE the default PCC rule in the roaming network, the default PCC rule that can directly use home network to select is set up default bearer, can adopt above-mentioned execution mode to select default PCC rule.Highlight the situation that needs to be chosen in the default PCC rule in the roaming network below for UE.

In the time need being chosen in default PCC rule in the roaming network for UE, roaming network and/or home network can be determined the default PCC rule of this UE in roaming network according to carrier policy and/or roaming agreement, may need default PCC rule or its identification number in home network with reference to this UE this moment; Perhaps, can be mapped as the default PCC rule in roaming network according to predetermined mapped mechanism with the default PCC rule of this UE in home network.

Such as, when determining the default PCC rule of this UE in roaming network according to carrier policy and/or roaming agreement, one of can be in the following manner be chosen in default PCC rule in the roaming network for the UE of roaming by roaming network:

(1) UE is in attaching process, identification number by the default PCC rule that will expect is carried at and adheres in the message, send to roaming network, and the identification number that identifies the default PCC rule of carrying up is that home network distributes or roaming network distributes, home network distributes in this way, then needs roaming network to be converted into the identification number of the corresponding default PCC rule of roaming network according to carrier policy and/or roaming agreement.PCEF by roaming network activates corresponding PCC rule according to this identification number, for the UE of this roaming sets up default bearer.

(2) if the identification number of the default PCC rule of the UE of roaming exists as subscription data in HSS, the identification number of the default PCC rule that can obtain home network by user contracting data request/give information then, and be converted into the identification number (entity of finishing the identification number conversion can be HSS, V-PCEF, H/V-PCRF etc.) of the corresponding default PCC rule of roaming network according to carrier policy and/or roaming agreement.

(3) if select the default PCC rule of UE according to QoS (as Label, signatory qos parameter etc.), class of service, APN or charge information, and above-mentioned parameter is present among the HSS with the form of subscription data, then can be by user contracting data request/give information and obtain above-mentioned parameter, and utilize these parameters to be chosen in the corresponding default PCC rule of roaming network according to carrier policy and/or roaming agreement by roaming network.

(4) if select the default PCC rule of the UE of roaming by H-PCRF (PCRF of home network), the identification number of the default PCC rule of this UE that can obtain home network by PCC rule request/give information then, and be converted into the identification number of the corresponding default PCC rule of roaming network according to carrier policy and/or roaming agreement by roaming network.

(5) if select default PCC rule according to QoS, class of service, APN or charge information, and above-mentioned parameter is provided by H-PCRF, then can be by PCC rule request/give information and obtain above-mentioned parameter, and utilize these parameters to be chosen in the corresponding default PCC rule of roaming network according to carrier policy and/or roaming agreement by roaming network.

Need to prove, if it is infeasible that the identification number (H-ID) of above-mentioned default PCC rule by home network obtains the method for identification number (V-ID) of default PCC rule of roaming network, then can adopt predetermined mapped mechanism the default PCC rule of H-ID correspondence to be mapped to the default PCC rule of roaming network, and the entity of finishing this mapping can be positioned at that home network also can be positioned at roaming network or consulted to decide through PCC by home network and roaming network, finally obtains the V-ID of roaming network.In specific implementation, it is also conceivable that the default PCC rule in the roaming network is divided into two classes, that is: be directed to ownership place user's local default PCC rule and the default PCC rule of roaming that is directed to the roamer.

Under roaming scence, if adopt the roaming network framework that goes out the SGi interface from roaming network, and V-PCEF (PCEF of roaming network) needs to carry out alternately (having the S9 interface this moment between V-PCRF and H-PCRF) by V-PCRF (PCRF of roaming network) and H-PCRF, and then corresponding flow chart as shown in figure 11.Under this scene,, then need to be chosen in default PCC rule in the roaming network for UE because of PCEF is positioned at roaming network certainly.Need to prove that V-PCRF is depicted as dotted line in this figure, represent that this process exists V-PCRF not participate in the possibility of this process, that is: V-PDN SAE gateway (the PDN SAE gateway of roaming network) exists interface to be directly connected to H-PCRF.

Under roaming scence, if adopt the roaming network framework that goes out the SGi interface from home network, then the service SAE gateway of roaming network need be undertaken alternately by S8 interface and H-PDN SAE gateway (the PDNSAE gateway of home network), and corresponding flow process as shown in figure 12.Under this scene, whether need look concrete condition decision needs to be chosen in default PCC rule in the roaming network for UE, if do not have the PCEF function,, then generally be not required to be UE and be chosen in default PCC rule in the roaming network such as only on H-PDN SAE gateway, having the PCEF function at roaming network; In case if there is the PCEF function in roaming network, have the PCEF function, then need be chosen in default PCC rule in the roaming network for UE certainly such as the service SAE gateway of roaming network.

This shows that present embodiment can make roaming network can select default PCC rule for the UE in the roaming equally.

The method that the default PCC rule of home network is mapped as the default PCC rule of roaming network in the present embodiment not only can be applied to default bearer and also can be applied to dedicated bearer.

Such as, employing goes out the roaming network framework of SGi interface from roaming network, then the idiographic flow of setting up dedicated bearing at roaming network as shown in figure 24, in step 2401a, H-PCRF PCC rule that this is professional relevant (i.e. the default PCC rule of the roaming network that is mapped to according to the default PCC rule of home network) is handed down to V-PCRF.Then, in step 2401b, V-PCRF will issue relevant PCC rule and give PDN SAE gateway.Step 2402 to step 2409 is that flow process is set up in the carrying of initiating a normal network side triggering, and is same as the prior art, do not repeat them here.In step 2410a, PDN SAE gateway is to the response message of the relevant PCC rule of V-PCRF affirmation, and in step 2410b, V-PCRF responds the response message of PCC rule to H-PCRF.Wherein, the entity of finishing this mapping can be positioned at home network and also can be positioned at roaming network or consulted to decide through PCC by home network and roaming network.

The 15 execution mode of the present invention relates to default bearing establishing method for wireless network, in the present embodiment, when UE is attached to network side, choose equipment of the core network (as MME, ePDG, PDN SAE gateway, service SAE gateway etc.) by eNB, present embodiment is chosen MME and service SAE gateway with eNB, and network side selects default PCC rule to describe for example according to class of service, APN or the charge information of UE.Idiographic flow as shown in figure 25.

In step 2501, the Attach Request message that UE initiates at first sends to eNB by the RRC signaling.

Then, in step 2502, the parameter (as P-TMSI) that eNB carries according to the Attach Request message of UE etc. is chosen suitable MME, and is that this UE selects service SAE gateway.This eNB can be by the configuration relation between reference and service SAE gateway, route metric, and information such as load link circuit condition are for this UE selects a suitable service SAE gateway.

Then, in step 2503, eNB transmits Attach Request message to the MME that selects, and carries the identification number (this identification number can be the IP address of service SAE gateway, but also is not limited to the IP address) of service SAE gateway in this Attach Request message.

Step 2504 is identical to step 915 with step 902 respectively to step 2517, does not repeat them here.

What deserves to be mentioned is, select the situation of service SAE gateway also may occur in the renewal of tracking area position when (Tracking Area Update is called for short " TAU "), select service SAE gateway by eNB by eNB.This mainly occurs under the scene of crossing over the MME/UPE pond, or it is unusual network to occur, and network needs under the scene of Operation and Maintenance.

In addition, need to prove, in the respective embodiments described above, when network side can't be selected a default PCC rule or abnormal conditions take place for UE, can be that UE selects a default PCC rule according to carrier policy by network side, and according to this default PCC rule, for UE sets up corresponding default bearer.

The 16 execution mode of the present invention relates to the wireless network default bearer and sets up system, as shown in figure 15, comprises: memory module is used to preserve each pre-configured default PCC rule of network side; Select module, be used for attaching process, from each default PCC rule that memory module is preserved, select a default PCC rule at UE; Set up module, be used for according to selecting the selected default PCC rule of module to set up corresponding default bearer for UE.The default PCC rule of pre-configured each is a corresponding class default bearer respectively.This shows that when setting up default bearer for UE, as long as select one from limited several rules that configured, thereby make that the workload of handling is less relatively, processing procedure is very fast relatively, has reduced the setup delay of default bearer.

Wherein, select module to select one of in the following manner default PCC rule: the default PCC rule that generates according to the default PCC rule of the Information Selection in the subscription data of UE, according to PCRF or the identification number of default PCC rule select default PCC rule, qos parameter, class of service, APN or charge information according to UE to select default PCC rule or the identification number of the default PCC rule of the expectation that reports according to UE in attaching process, select default PCC rule.Make present embodiment to realize flexibly.

If UE is in roaming network, then difference as the case may be selects module for the default PCC rule that this UE selects, and may be the default PCC rule of this UE in home network; It also may be the default PCC rule of selecting for this UE in roaming network.Specifically can be mapped as the default PCC rule in roaming network according to one of following mode with the default PCC rule of this UE in home network:

(1) roaming network and/or home network are determined the default PCC rule of this UE in roaming network according to carrier policy and/or roaming agreement, may need the default PCC rule in home network with reference to this UE;

(2) according to predetermined mapped mechanism with the default PCC rule of this UE in home network, be mapped as the default PCC rule in roaming network.

The system of present embodiment can also comprise judge module, is used for judging whether set up module has existed the selected default PCC rule of selection module.There has been the selected default PCC rule of this selection module in the module if this judge module is judged to set up,, notified this to set up the selected default PCC rule of module then by set up the identification number that module sends default PCC rule to this; There is not the selected default PCC rule of this selection module in the module as yet if judge module is judged to set up, then selected default PCC rule sent to this and set up module, and set up module by this and preserve this default PCC rule.In order to avoid repeat to send Rule content, reduced the traffic between the heterogeneous networks entity, thereby saved system resource to PCEF.

Need to prove that each module in the present embodiment is logic module, in actual applications, various physics realization mode can be arranged.

In sum, in embodiments of the present invention, pre-configured at least one the default PCC rule of network side, and in advance default bearer is classified, the corresponding pre-configured default PCC rule of every class default bearer, in the attaching process of UE, from each pre-configured default PCC rule, select one, PCEF sets up corresponding default bearer according to selected default PCC rule for this UE.Owing to carried out pre-configured to default PCC rule, therefore do not need each UE is generated a rule, when setting up default bearer for UE, as long as from limited several rules that configured, select one, thereby make that the workload of handling is less relatively, processing procedure is very fast relatively, has reduced the setup delay of default bearer.And,, the number of pre-configured default PCC rule is controlled in the limited scope processing procedure when further having accelerated to set up default bearer by in advance default bearer being classified for UE.

Network side can be classified to default bearer in advance according to expenses standard, business prototype, business model, signatory modes such as user class, when the number that guarantees pre-configured default PCC rule is limited, can be neatly provide different personalized services for the user of different stage.

If default PCC rule is pre-configured to be in PCEF, then select the network entity of default PCC rule not need to send Rule content to PCEF, as long as send out the sign of rule, reduced the traffic between the heterogeneous networks entity, thereby saved system resource.

Even default PCC rule is not pre-configured to be in PCEF, but because PCEF preserves paid-in default PCC rule, therefore, if sent to this PCEF before the selected default PCC rule, then do not need repetition to send Rule content to PCEF yet, reduce the traffic between the heterogeneous networks entity, thereby saved system resource.

Network side can be selected default PCC rule according to multiple mode, as selecting according to subscription data or according to the qos parameter selection etc., making embodiments of the present invention to realize flexibly.
