The embodiment of the invention one provides a kind of acquisition methods of acquisition strategy controlled entity address of address, is applied to comprise that as shown in Figure 1, this method may further comprise the steps in the system of fixed network and mobile network's fusion:
In the embodiment of the invention, stored the corresponding relation of address of fully qualified domain name FQDN and the said second tactical management entity of said Home eNodeB in the said dns server; The said first tactical management entity comprises to the address of the tactical management entity of dns server inquiry fixed network: the said first tactical management entity obtains the FQDN of said Home eNodeB according to the E-UTRAN Cell Global Identifier symbol ECGI of said Home eNodeB; The said first tactical management entity is inquired about the address of the second tactical management entity corresponding with said FQDN to said dns server according to the FQDN of said Home eNodeB.
The process of the corresponding relation of the address of the FQDN of the said Home eNodeB of storage and the said second tactical management entity is specially: the address that evolved Home eNodeB management system HeMS or said Home eNodeB obtain the said second tactical management entity in the said dns server; Said HeMS or said Home eNodeB obtain the FQDN of said Home eNodeB according to the ECGI of said Home eNodeB, and the corresponding relation of the address of the FQDN of said Home eNodeB and the said second tactical management entity is stored in the said dns server.
Said HeMS obtains the address of the said second tactical management entity; Comprise: when said HeMS carries out address validation to said Home eNodeB; Obtain the IP address of said Home eNodeB or its access device (be the access device of Home eNodeB, include but not limited to home router, DSL Model etc.); Said HeMS is according to the mapping relations of the address of stored IP address scope and the said second tactical management entity in the IP address lookup database of the access device of the IP address of said Home eNodeB or said Home eNodeB, the address that obtains the said second tactical management entity; Perhaps, the said HeMS address that obtains the said second tactical management entity according to the network element of IP address in fixed network of the access device of the IP address of said Home eNodeB or said Home eNodeB.
Said Home eNodeB obtains the address of the said second tactical management entity; Comprise: said Home eNodeB receives based on the message of dynamic host configuration protocol DHCP agreement or based on neighbours and finds the router advertisement RA message of ND agreement, and from said based on the address that obtains the said second tactical management entity the message of DHCP agreement or the RA message based on the ND agreement; Wherein, said based on the address of having carried the said second tactical management entity in the message of DHCP agreement or the RA message based on the ND agreement.
The first tactical management entity among the said mobile network confirms that user equipment (UE) passes through Home eNodeB and inserts; Comprise: when packet data network gateway PGW judges said UE according to the closed signed user group CSG relevant parameter in the bearer messages or ECGI relevant parameter is when inserting through said Home eNodeB, and the said first tactical management entity receives said UE that said PGW the reports information through said Home eNodeB access; Perhaps, the said first tactical management entity confirms that according to CSG relevant parameter in the said bearer messages or ECGI relevant parameter said UE inserts through said Home eNodeB.
In the embodiment of the invention, the said first tactical management entity comprises: "Policy and Charging Rules Function PCRF; The said second tactical management entity comprises: broadband policy and billing function BPCF.
In order more clearly to set forth the technical scheme that the embodiment of the invention provides, the acquisition methods of this policy control entity address is discussed in detail below in conjunction with concrete applicable cases.In each following applicable cases; Tactical management entity among the mobile network is with PCRF (Policy and Charging RulesFunction; "Policy and Charging Rules Function) describes for example; Tactical management entity in the fixed network describes for example with BPCF (BroadBand Policy and Charging Function, broadband policy and billing function).Certainly, in practical application, tactical management entity among this mobile network and the tactical management entity in the fixed network can also be other functional entity, explanation no longer in detail in the embodiment of the invention.
The embodiment of the invention two provides the acquisition methods of a kind of policy control entity address; In the present embodiment; Relate to UMTS (Universal Mobile Telecommunications System; UMTS), LTE mobile network and broadband access network (being fixed network), when UE inserted through Femto, mobile network's policy control entity obtained the address of the tactical management entity of the fixed network that Femto inserted.
In the present embodiment; (processing procedure in the network of UMTS network and other standard and LTE network class are seemingly with the LTE network; Repeat no more in the embodiment of the invention) describe for example; As shown in Figure 2, the application scenarios sketch map when inserting mobile network through the Femto that is connected in the fixed network (among the present invention be that example describe with the BBF network) for UE.
As can be seen from Figure 2, because 3GPP Femto has passed through BBF (BroadBand Forum, broadband forum) network to the link of core net SeGW (Security Gateway, security gateway).For example, RG (residential gateway), AN (Access Network, Access Network), BRAS (Broadband RemoteAccess Server, Broadband Remote Access Server)/BNG network elements such as (Broadband Network Gateway, broadband services gateways).
When UE passed through the Femto access to mobile network, in order to let fixed network to the mobile service data of wherein transmission service quality guarantee is provided, this just required the PCRF among the mobile network that the BPCF in the fixed network is informed in relevant quality of service policy and requirement.Yet there is the IPsec encryption tunnel between SeGW and the Femto; So when UE inserts through Femto; Fixed network can't learn that wherein data packets for transmission is that UE is transferred to the packet among the mobile network through Femto; Therefore the BPCF address that can't initiatively inform PCRF self; PCRF informs BPCF in fixed network with relevant quality of service policy with requiring for the BPCF that finds that can be correct, and need know following message: (1) UE is linked among the mobile network through Femto (rather than common base station); (2) address of the BPCF in the fixed network of Femto connection.
Based on above-mentioned situation, as shown in Figure 3 in the acquisition methods of the policy control entity address that the embodiment of the invention two provides, may further comprise the steps:
In this step, when Femto powered on or restarts, this Femto need carry out initial access procedure, and from the corresponding initial configuration parameter that the webmaster acquisition needs self, gave unnecessary details no longer in detail in this process embodiment of the invention.
In the embodiment of the invention,, can obtain the IP address of BPCF, also can obtain the IP address of BPCF by Femto by HeMS according to the needs of reality.
(1) HeMS obtains the IP address of BPCF.
Wherein, the fixed network that HeMS can insert through the IP address validation location Femto to Femto, and the IP address of definite BPCF.
Because BPCF often manages the user of one or more address fields and inserts, therefore, HeMS HeMS capable of using verifies the address of Femto, confirms as the fixed network that Femto provides service, and then knows the IP address of BPCF in this network segment.
Setting forth HeMS in detail below in conjunction with HeMS configuration diagram shown in Figure 4 and obtain the address of BPCF through the mode of address validation, is that example describes with the LTE network, and processing procedure is similar in the UMTS network, repeats no more in the embodiment of the invention.
Concrete, HeNB (being Femto) need to obtain to HeMS place corresponding configuration parameters, and HeMS can verify to the geographical position of HeNB when initially powering on, and determining the fixed network that HeNB belongs to, thereby makes things convenient for operator to manage and charges.Wherein, The verification mode in geographical position includes but not limited to IP address (like the IP address of the local gateway of HeNB or its access) verification mode, GPS (Global Positioning System, global positioning system) verification mode, monitor around macro base station cell information verification mode.
After HeMS carried out address validation to HeNB, then HeMS obtained to include but not limited to for HeNB provides the mode of the BPCF address in the fixed network of service:
A) mobile operator and fixed network operator are notified the mapping relations of the IP address of network ip address scope and BPCF to mobile operator by the fixed network operator when setting up cooperative relationship, and form a subscribed database.When the IP address of knowing HeNB (perhaps; The IP address of the access device of HeNB; For example, the IP address of home router, the IP address of DSL ModelIP etc.) afterwards, according to the IP address of this HeNB or the IP address of its access device; Then HeMS can get in this subscribed database the network ip address scope of inquiry storage and the mapping relations of the IP address of BPCF, thus the address of definite BPCF.
B) HeMS certain network element (this network element can be selected arbitrarily according to actual conditions) in fixed network is inquired about, to obtain the address of BPCF.
(2) Femto obtains the IP address of BPCF.
Femto obtains to include but not limited to for it provides the mode of BPCF address of the fixed network of service: Femto can be through expanding DHCP (Dynamic Host Configuration Protocol; DHCP) agreement is perhaps expanded ND (Neighbour Discovery; Neighbours find) mode of RA (Router Advertisement, the router advertisement) message of the agreement IP address that directly obtains corresponding BPCF.
Concrete, Femto is when inserting fixed network, for the information that can obtain IP address or other network (like dns address etc.); Often need send DHCP (DHCPv4 or DHCPv6) request; In the embodiment of the invention, through defining a new DHCP option, Femto is as an IP access device; In its dhcp message, add this new option, show the demand of Femto the BPCF address to Dynamic Host Configuration Protocol server.When Dynamic Host Configuration Protocol server is checked through the request of this option; Need be in the message of returning with IP address or FQDN (the Fully Qualified Domain Name of BPCF; Fully qualified domain name) adds, thereby make Femto can directly obtain the IP address of BPCF.
In addition, for the access of IPv6, Femto also can realize obtaining of BPCF address through the RS/RA message of expansion ND agreement.Wherein, in the ND of IPv6 agreement, router is given main frame through RA message with configuration information (like network prefix, the dns server address etc.) announcement of link-local.
Through expansion RS/RA mechanism, define the type of new option, router can carry the address of BPCF in RA message.Based on this, Femto can indicate the address information of wanting router to reply BPCF in RS message, and after receiving this information, then router need send to Femto with the address of BPCF in RA message, thereby makes Femto can directly obtain the IP address of BPCF.
Wherein, when obtaining the IP address of BPCF by HeMS in the step 302, then need upgrade dns server by HeMS; When obtaining the IP address of BPCF by Femto in the step 302, then need upgrade dns server by Femto.
Concrete; Behind the IP address of HeMS or Femto acquisition BPCF; This HeMS or Femto can utilize ECGI (the E-UTRAN Cell Global Identifier of Femto; E-UTRAN Cell Global Identifier symbol) generate a FQDN, the mode of using Dynamic (dynamically) DNS then is written to the corresponding relation of the IP address of FQDN and BPCF in the dns server.
Example below in conjunction with a structure FQDN is further explained the embodiment of the invention.
Wherein, the ECI among the ECGI (E-UTRAN Cell Identifier, E-UTRAN cell identifier) has 28bit, and this field (or be converted into ascii character through the mechanism of carrier customization) and other operator's relevant information are constructed FQDN:
ECGI<Femto-ECGI>.bpcf.epc.mnc<MNC>.mcc<MCC>.3gppnetwork.org
After constructing FQDN, HeMS or Femto just can be deposited into the mapping relations of FQDN and BPCF address in the corresponding D NS server.
Concrete; When UE switches to Femto cell (sub-district) or UE and initially inserts through Femto cell; Then the business datum of UE has been passed through fixed network and mobile network; In order to guarantee quality of service, need to communicate between PCRF and the BPCF, make PCRF can the parameter of corresponding strategies be informed to BPCF.
Concrete, PCRF perception UE includes but not limited to through the mode that Femto inserts:
(1) PGW (PDN Gateway; Whether packet data network gateway) can judge current UE according to parameters such as relevant CSG in the carrying foundation that receives, the bearing modification request message (Closed Subscriber Group, closed signed user group) or ECGI is to insert through Femto.If then PGW is to notify to PCRF through the information that Femto inserts with UE, PCRF perception UE inserts through Femto.
(2) if when storing the access information of UE such as CSG among the PCRF, then PCRF directly perception UE whether be that mode through Femto is linked in the network.Be whether be through Femto insert to PCRF if can be directly judging current UE according to parameters such as relevant CSG or ECGI.For example; If PCRF can obtain the relevant identification information (like User CSG Informaiton) of Femto in the flow process of PCEF Initiated IP-CAN Session Establishment/Modification, then PCRF directly the perception user insert through Femto.
Judge with PGW below, and the information whether UE inserts through Femto is notified to PCRF is that example is elaborated.When UE initially adhere to, TAU (Tracking Area Update; Tracing section updating), reach when switching; If when correlated process occurs in the Femto, then MME (MobileManagement Entity, Mobility Management Entity) will send Create Session Request (setting up conversation request) or Modify Bear Request message such as (bearing modification requests); This message will be passed through SGW (Serving Gateway, gateway) and arrived PGW.
After PGW receives related news, can utilize following parameters to judge whether UE inserts through Femto:
(1) User CSG Information, the UserCSG Information among the Create Session Request that PGW receives often contains parameters such as Femto distinctive CSG Access Mode and CSG ID.Therefore, PGW can confirm through the feature field in this message of inspection whether current UE inserts through Femto.
(2) eNB ID/HeNB ID: operator can be special number section of Femto devices allocation in advance, and PGW can judge whether current UE inserts through Femto through the number segment at corresponding eNB ID/HeNB ID place among the analysing ECG I.
When PGW judges after UE inserts through Femto, need this message be reported to PCRF through signaling.For example; Can in PCEF Initiated IP-CAN SessionEstablishment/Modification flow process between PGW and the PCRF or message, add a new flag bit field FemtoFlag, and whether give PCRF with UE through the information reporting of Femto access through Femto Flag.
Wherein, when PCRF perception UE is when inserting through Femto, PCRF need utilize FQDN of ECGI structure of Home eNodeB, and utilizes this FQDN to initiate inquiry to dns server, to obtain the IP address of BPCF.The mode of this structure FQDN is identical with the make in the step 303, repeats no more at this.
Concrete; When PCRF is checked through Femto Flag flag bit; When perhaps directly basis is judged the user through the Femto access like the information of USER CSGInformation and so on; PCRF need generate FQDN according to the ECGI that UE inserts, and initiates inquiry to dns server, and dns server then returns the address of BPCF to PCRF.
It should be noted that after knowing the IP address of BPCF then PCRF promptly can initiate the S9* session to BPCF according to the IP address of BPCF, carries out the coordination and the negotiation of strategy, gives unnecessary details no longer in detail in this process embodiment of the invention.
In addition; In the short time, repeatedly inquire about same address; PCRF can be according to preset strategy (like cache-time) after obtaining the address of BPCF, and the address corresponding relation buffer memory of IP-CAN Session and BPCF is got up; In the time of need reusing the address of this BPCF during in order to bearing modification, deleting load-bearing,, IP-CAN Session removes relative recording after stopping.
In sum, through adopting the embodiment of the invention technical scheme is provided, (1) obtains the IP address of access network policy controlled entity with the mode that has Femto location test or expansion DHCP, RS/RA message now, and thinking is simple, is convenient to use.(2) make full use of the mechanism that has FQDN now, to the change reduction as far as possible of network.(3) its FQDN is identified accurately simple through Femto relevant informations such as ECGI.(4) in existing signaling message, add new field and carried necessary information, do not introduced new interface.
