Use the technical scheme that the embodiment of the invention provided, Home eNodeB can report the local breakout LBO function of self in advance to network side, when UE when the local IP of network side request inserts, network side is except judging whether UE is authorized to carry out the local IP access, also whether have the LBO function and judge whether to carry out local IP access processing according to Home eNodeB, with avoid owing to Home eNodeB does not possess that local IP that the LBO function causes inserts can't correct execution, reduce invalid flow process and Signalling exchange, improve the stability of system.
Further, after the local IP of core net refusal UE inserts request, can also send Reason For Denial to UE.Avoiding when the family base station does not possess the LBO ability, UE initiates the situation that local IP inserts request repeatedly and takes place, thereby further reduces the mortality that carrying is set up.
In order to make those skilled in the art understand technical scheme of the present invention better,, the specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment one:
For EPS (Evolved Packet System, evolved packet system), the entity of carrying out the function of Home eNodeB is called HeNB (Home Evolved NodeB, family's evolution base station), the equipment of the core network of carrying out the LIPA judgement is MME (Mobility Management Entity, Mobility Management Entity), can set up one separately and be used for the flow process that LIPA judges, also LIPA can be judged to be combined in and adhere to, separate, service request, in the flow processs such as position renewal, below LIPA is judged being combined in attachment flow is that example describes: in attachment flow, relate to step that LIPA judges as shown in Figure 3, comprising:
S101, UE sends to MME and inserts request (Attach Request) message, a local ip breakout sign---Local IP APN (Local IP Access Point Name, local IP Access Point Name) shows that then UE is to network requests LIPA if carry in this message.
S102, HeNB uses LBO Indication (local breakout Function Identification) to represent self whether to support local breakout LBO function, and will identify together to be carried in S1 applying portion (S1-AP) message with self HeNB ID and offer MME, described S1-AP message can be to connect to set up request message S1Setup Request.
Wherein, can represent whether HeNB supports the LBO function, also can represent whether HeNB supports the LBO function, and the embodiment of the invention includes but not limited to aforesaid way with the two states of LBO Indication sign with whether carrying LBO Indication.
S103, MME is to the subscription data of HSS (Home Subscriber Server, home signature user register) request UE.Mobility Management Entity MME inquires about in home signature user register HSS and whether carries local IP in the subscription data of described subscriber equipment and insert sign LIPA Indication.
S104, HSS responds to the request of MME, returns the subscription data of UE to MME.
When UE is signed in to network, network can determine whether to allow this user to use LIPA, if then the subscription data at UE utilizes LIPA Indication (local IP inserts sign) to represent whether network authorizes this UE to carry out LIPA, and subscription data is stored among the HSS.
Wherein, can represent whether network authorizes this UE to carry out LIPA, also can represent whether network authorizes this UE to carry out LIPA with the two states of LIPA Indication sign with whether carrying LIPA Indication.And, it will be appreciated by those skilled in the art that, for realizing purpose of the present invention, MME also can not ask the complete subscription data of UE to HSS, but adopt the mode of inquiring about, be informed in the UE subscription data of preserving among the HSS whether carry LIPA Indication, perhaps know the state of this sign.
S105, MME carry out LIPA to UE and judge, determine whether that according to judged result UE is carried out LIPA to be handled.The idiographic flow of judging can be referring to shown in Figure 4:
S105a, MME inserts judgement substantially to UE.
As privately owned equipment, Home eNodeB only allows specific groups of users to insert.These groups of users that are allowed to access are called CSG (Closed Subscriber Group, limit groups of users), only allow the resident sub-district of CSG to be called the CSG sub-district, each CSG sub-district all has unique CSG ID (Closed Subscriber Group Indicator limits user's group id).For a terminal, can add a plurality of CSG sub-district, therefore, on the HSS under terminal and this terminal, all can preserve a ACL (Allowed CSG List, allow to limit user group list), record allows the CSG ID of all CSG sub-districts of this terminal access in ACL.
In the present embodiment, the CSGID that judges the CSG sub-district, HeNB place that UE will insert by MME whether in ACL, if, then carry out S105c, for UE sets up the default bearer of core net and execution in step S105b; Otherwise, carrying out s105e, refusal UE inserts, and alternatively, can further send #25 message (Not authorized for this CSG) to UE, informs error reason.
S105b, MME judge according to the LIPA Indication in the UE subscription data whether UE is authorized to carry out LIPA, and according to the LBO Indication that HeNB reports, judge whether HeNB supports local breakout LBO function.
In this step, MME judges whether UE is authorized to carry out LIPA, judges whether HeNB supports that two steps of local breakout LBO function can be in no particular order in proper order.If two conditions all satisfy, promptly UE is authorized to carry out LIPA and HeNB also supports local breakout LBO function, then carries out S105c and S105d; Do not support local breakout LBO function if judge UE uncommitted execution LIPA or HeNB, then only carry out S105c.
S105c, MME are the default bearer that UE sets up core net.
Need to prove, satisfy at UE under the situation of the described basic access Rule of judgment of s105a no matter whether MME accepts the LIPA request of UE, MME can set up the default bearer of core net for UE.
S105d, MME are that UE sets up local IP default bearer.
As a kind of UE is carried out the specific implementation that local IP inserts processing, in the present embodiment, when MME accepts the LIPA request of UE, will set up local default bearer for UE.
Wherein, local IP default bearer is set up process and is: L-SGW (the Local Serving Gateway that Local IPAPN that MME at first provides according to UE and HeNB ID select HeNB this locality, the local service gateway) and L-PGW (Local PDN Gateway, local grouped data network gateway), send to selected L-SGW then and set up default bearer request message (Create Default Bearer Request), this message further is sent to L-PGW (Local PDN Gateway, local grouped data network gateway), L-PGW sets up default bearer response message (Create Default Bearer Response) by follow-up L-SGW of turning back to and MME's, for UE sets up local IP default bearer.
S105e, MME refusal UE inserts.
If UE does not satisfy the described basic access Rule of judgment of s105a, MME will directly refuse the access of this UE, and can further send #25 message (Not authorized for this CSG) to UE, inform error reason.
Present embodiment is LIPA to be judged be combined in the attachment flow, correspondingly to the dual mode that establishes of local IP default bearer:
A kind of is that network is when setting up the core net default bearer for UE, for UE sets up local IP default bearer.
Another kind be network in the first attaching process of UE, when setting up the core net default bearer, not for UE sets up local IP default bearer, just carrying LIPA Allowed indication information in adhering to acceptance (Attach Accept) message sends to UE.When UE asked local IP operation, UE initiated attaching process once more, and this moment, network was again for UE sets up local IP default bearer, so that UE carries out the LIPA business.
Present embodiment is to judge that with LIPA being combined in attachment flow is that example describes, and in actual applications, LIPA can be judged also to be combined in the flow processs such as separation, service request, position renewal that these do not influence realization of the present invention.Need to prove that above-mentioned S105a is the basic determining step that inserts, this step does not influence the realization of the object of the invention.For example, when MME or other equipments of the core network had carried out basic the access when judging in advance in other flow processs, then carrying out before LIPA judges, just can no longer carry out the step of basic access judgement.
In the present embodiment, when UE asks local IP to insert, MME need carry out whether the judgement of two aspects: UE is authorized to carry out local IP access and whether Home eNodeB has local breakout LBO function, when having only above-mentioned two conditions all to satisfy, just UE is carried out local IP and inserts processing.Otherwise the local IP that MME will refuse UE inserts request.
Further, after the local IP of core net refusal UE inserts request, can also send Reason For Denial to UE.According to the judged result of S105b, Reason For Denial can comprise following three kinds:
1) LIPA Not Allowed (the local IP of the uncommitted execution of UE inserts);
2) HeNB LBO Disable (Home eNodeB does not have local breakout LBO function);
3) LIPA Not Allowed and HeNB LBO Disable (the local IP of the uncommitted execution of UE inserts and Home eNodeB does not have local breakout LBO function).
UE can carry out corresponding subsequent processing according to the Reason For Denial that receives.Particularly when the family base station does not possess local breakout LBO function, can avoid UE to initiate local IP repeatedly and insert request, thereby further reduce the mortality that carrying is set up.
Embodiment two:
Embodiment one is an example with the EPS system, and the local IP connection control method of Home eNodeB is illustrated.At UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) in, the entity of carrying out the function of Home eNodeB is called HNB (Home NodeB, Home eNodeB), the equipment of the core network of execution LIPA judgement is SGSN (Service GPRS Support Node, a GPRS serving GPRS support node), and UE is in UMTS system attaching process, SGSN only inserts judgement substantially to UE, and when UE carried out the service request process, the LIPA that carries out UE again judged.
In the UMTS system, when UE was attached to network, SGSN was according to the subscription data of UE, the CSG ID that judges HNB (Home NodeB, Home eNodeB) the CSG sub-district, place that UE will insert whether in ACL, if, then allow the UE access; Otherwise refusal UE inserts.And can further send #25 message (Not authorized for this CSG), inform the UE Reason For Denial to UE.
Allow at network under the prerequisite of UE access, when UE carries out the service request process, carry out LIPA again and judge, in the present embodiment, the LIPA judgement is combined in PDP (Packet Data Protocol, the packet oriented protocol data) context active flow, as shown in Figure 5, may further comprise the steps:
S201, UE send to SGSN and activate in PDP Context request (the Activate PDP Context Request) message, if carry Local IP APN in this message, show that then UE is to network requests LIPA.
S202, SGSN carry out LIPA to UE and judge, determine whether that according to judged result UE is carried out LIPA to be handled.The idiographic flow of judging can be referring to shown in Figure 6:
S202a, SGSN judge according to the LIPA Indication in the UE subscription data whether UE is authorized to carry out LIPA, and according to the LBO Indication that HNB reports, judge whether HNB supports local breakout LBO function.If two conditions all satisfy, promptly UE is authorized to carry out LIPA and HeNB also supports local breakout LBO function, then carries out S202c; Do not support local breakout LBO function if judge UE uncommitted execution LIPA or HeNB, then carry out S202b.
In the UMTS system, SGSN obtains MME in the mode of LIPA Indication and the EPS system, and to obtain the mode of LIPA Indication similar: preserve the subscription data of UE among the home signature user register HSS, SGSN inquires about in home signature user register HSS and whether carries local IP in the subscription data of described subscriber equipment and insert sign LIPA Indication; And HNB reports the LBO function of self, can adopt following mode: HNB to carry LBO Indication in register requirement (HNB Register Request) message and give HNB-GW (femto gateway); HNB-GW is reported to SGSN with the HNB ID of HNB and corresponding LBO Indication in RANAP (Radio Access Network Application Part, Radio Access Network Application Part) signaling.
S202b, the local IP of SGSN refusal UE inserts request.And can in the activation PDP Context response message of S203, carry Reason For Denial.According to the judged result of S202a, Reason For Denial can comprise following three kinds:
1) LIPA Not Allowed (the local IP of the uncommitted execution of UE inserts);
2) HNB LBO Disable (Home eNodeB does not have local breakout LBO function);
3) LIPA Not Allowed and HNB LBO Disable (the local IP of the uncommitted execution of UE inserts and Home eNodeB does not have local breakout LBO function).
S202c, SGSN are that UE activates the PDP Context that local IP inserts.
As a kind of UE is carried out the specific implementation that local IP inserts processing, in the present embodiment, when SGSN accepts the LIPA request of UE, will activate the PDP Context that local IP inserts for UE, and inform UE by the activation PDP Context response message of S203.
Wherein, the pdp context activation that local IP inserts is: L-GGSN (the Local Gateway GPRS Support Node that LocalIP APN that SGSN at first provides according to UE and HNB ID select HNB this locality, the local gateway GPRS Support Node), send to L-GGSN then and set up PDP Context request (Create PDP Context Request) message, after L-GGSN has responded PDP Context message (Create PDP Context Response), activate the PDP Context of LIPA.Thereby allow UE to use the local IP access service of HNB.
The method that present embodiment provided is applicable to the local IP access control of Home eNodeB of UMTS system.In the UMTS system, the entity that carries out the LIPA judgement is SGSN, and LIPA judged be combined in the PDP context activation flow process to have only that local IP inserts and Home eNodeB when having two conditions of LBO function and all satisfying when UE is authorized to carry out, just be the PDP Context of UE activation LIPA.Thereby avoid owing to Home eNodeB does not possess that local IP that the LBO function causes inserts can't correct execution, reduces invalid flow process and Signalling exchange, the stability of raising system.
In addition, UE can carry out corresponding subsequent processing according to the Reason For Denial that receives.Particularly when the family base station does not possess local breakout LBO function, can avoid UE to initiate local IP repeatedly and insert request, thereby further reduce the mortality that carrying is set up.
Embodiment three:
More than two methods that embodiment provided, be applicable to that UE has the situation of CSG ability, for example the UE of 3GPP R8 version.In order to guarantee the compatibility of system, should consider that also UE does not have the situation of CSG ability.In the embodiment of the invention, the UE of no CSG ability is called Pre-R8UE.For Pre-R8UE, it inserts judgement substantially and is carried out by HNB-GW or HNB, and the LIPA judgement is carried out by SGSN.
Carry out the basic situation about judging that inserts for HNB-GW or HNB, can preserve a CSG Member List (CSG member's tabulation) on HNB-GW or the HNB, if the sign of UE (for example IMSI International Mobile Subscriber Identity IMSI) then allows UE to be linked into core net in this tabulation, otherwise refusal UE inserts.And can further send #25 message (Not authorized for this CSG), inform the UE error reason to UE.
For the Pre-R8UE that inserts core net, LIPA judges the execution by SGSN, and the process of judgement can no longer describe in detail here referring to the associated description among the embodiment two.
