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

The disclosed method of the embodiment of the invention can be applied in as in Fig. 1 or the system shown in Figure 2.Wherein Figure 1 shows that the network architecture that adopts HNB, i.e. the network configuration of UMTS system; Figure 2 shows that the network architecture that adopts HeNB, i.e. the network configuration of EPS system.

In Fig. 1, show CSG cap.UE (terminal that possesses the CSG ability) and non-CSG cap.UE (terminal that does not possess the CSG ability); And in Fig. 2, only show CSG cap.UE.Because disclosed technical scheme relates to the control of LIPA or SIPTO in the embodiment of the invention, the CSG ability of itself and terminal has relation, and the therefore UE that mentions hereinafter is under situation about being not specifically noted, its CSG ability is not done qualification, judge and transfer to deterministic process.

Shown in Fig. 1 is HNB, optionally, HNB GW can also be arranged; And in Fig. 2, that illustrate is HeNB, optionally, HeNB GW can also be arranged.As previously mentioned, in this article, will use H (e) NB or base station to represent the general designation of HNB and HeNB, and use H (e) NB GW to represent the general designation of HNB GW and HeNBGW.In embodiments of the present invention, except can using H (e) NB GW, can also use to have similar functions with it, for example LIPA or SIPTO ability, base station are to other accessing gateway equipment of the aggregation feature of core net, data forwarding function etc.Therefore, this paper also uses the general designation of IAD one speech as this kind equipment, and H (e) NB GW only illustrates as a kind of being used for for example, does not represent to limit.In network, disposed under the situation of IADs such as H (e) NB GW, carried out interacting message by IADs such as H (e) NB GW between H (e) NB and SGSN or the MME; In network, do not dispose under the situation of IADs such as H (e) NB GW, directly carry out interacting message between H (e) NB and SGSN or the MME.

As previously mentioned and MME shown in Figure 2 can think the split of the chain of command function of SGSN shown in Figure 1, S-GW then can be regarded as the split of the user plane functions of SGSN.In embodiments of the present invention, relate to the chain of command functional description, will perhaps use the general designation of corresponding Chinese " Mobility Management Entity " with MME as an example as this class functional entity.And when relating to the description of user plane functions, will be as an example with S-GW (Serving Gateway, gateway).Described S-GW as shown in Figure 2, the functions such as route of the buffer memory the when service request that the grouping route that provides between E-UTRAN and the EPC, mobility anchor point, network initiate is provided, Lawful intercept, packet.Need to prove that those skilled in the art just are appreciated that without any creative work this expression for example limit, this general designation also be with functional description as the entity title, it must use corresponding title under the different network architectures.

MSC shown in Fig. 1 is mobile switching centre (Mobile Switching Center), and it is mainly the mobile phone of roaming services such as circuit-switched call, mobile management and GSM are provided in its service field.It does not participate in the flow process of the described method of the embodiment of the invention directly, and description hereinafter will not relate to.But in whole communication network, some operation related to the present invention may relate to the application of MSC.These application that relate to MSC can be operated according to prior art, and the embodiment of the invention is not got rid of these application to MSC.

Above network side entity belongs to VPLMM (Visit Public Land Mobile-communicationNetwork, visit public land mobile radio communication), next two entities will introducing then belong to HPLMN (Home Public Land Mobile-communication Network, local public land mobile radio communication).All show this two entities among Fig. 1 and Fig. 2.HSS (Home SubscriberServer, home signature user register) is GPRS and EPS (Evolved Packet System, evolved packet system) user contracting data and the permanent deposit position of routing iinformation.

The method of the IP flow Unloading Control that the embodiment of the invention discloses a kind of local IP access or select.As shown in Figure 3, concrete steps comprise:

Step 301, base station or IAD local maintenance LIPA or SIPTO allow member's tabulation.

Disclosed method in the present embodiment is specifically finished the access control of LIPA or SIPTO business by base station or IAD.This method goes for the Fig. 1 or the network architecture shown in Figure 2.Wherein, IAD is optional.

Base station local maintenance LIPA or SIPTO allow member's tabulation, and described tabulation is used to list the sign of the UE that permission inserts with LIPA or SIPTO mode.This tabulation can be with representing as LIPA or SIPTO MemberList.Be deployed with IAD in the network, this tabulation optionally can be maintained in this locality of IAD or this locality of base station.Present embodiment provides two kinds of optional generating modes of this tabulation, reference as an example:

1) according to carrier policy, pass through OMA DM (Open Mobile AllianceDevice Management by strategic server, Open Mobile Alliance terminal management agreement) mode allows member's tabulation to be handed down to base station or IAD LIPA or SIPTO, further, can also utilize OMA DM mode to allow member's tabulation to upgrade to described LIPA or SIPTO.The sign of UE can be the identity code of UE in described LIPA or SIPTO permission member's the identity code tabulation, for example can be IMSI (the International Mobile Subscriber Identity of described UE, international mobile subscriber identity), perhaps MSISDN (Mobile Subscriber Integrated Services Digital Network Number, mobile contracted user's comprehensive service digital net number).

2) base station or the IAD owner according to carrier policy in the base station or the local LIPA of generation of IAD or SIPTO allow member's tabulation, as LIPA or SIPTO Member List.The base station or the IAD owner also can carry out the member to this list and browse, add or operation such as deletion.The sign of UE can be IMSI or the MSISDN of UE among described LIPA or the SIPTOMember List.

Step 302, the LIPA or the SIPTO that receive from UE insert request.It can be an independent message that this LIPA or SIPTO insert request, also can be to adhere to request, position updating request, service request or the like.Be that described LIPA or SIPTO access control process can be independent processes, also can combine with other processes.If described LIPA or SIPTO insert request process and combine with other processes, then corresponding request can be counted as LIPA or SIPTO inserts request.For example, occur in the attaching process, then adhere to request and can be counted as described LIPA or SIPTO access request if described LIPA or SIPTO insert request.Described LIPA or SIPTO insert the sign of carrying described UE in the request, for example are IMSI or the MSISDN of described UE.

Step 303, if the sign of described UE, for example IMSI of described UE or MSISDN, in described base station or the IAD described LIPA or the SIPTO that safeguard allow then to allow described UE to carry out described LIPA or SIPTO business in member's tabulation.

By using the described method of present embodiment, base station or IAD local maintenance LIPA or SIPTO allow member's tabulation, when UE initiates LIPA or SIPTO request, report its sign to described base station or IAD, if described LIPA or the SIPTO that is identified at described base station or IAD local maintenance of described UE allows then to allow described UE to carry out LIPA or SIPTO business in member's tabulation.Like this, when LIPA or SIPTO business are carried out in the UE request, all take resources of core network when system need not to carry out access control at every turn, but finish access or SIPTO control, improved the execution efficient of system by base station or IAD.

After described UE was allowed to carry out described LIPA or SIPTO business, network side need be set up LIPA or SIPTO carrying for described UE.H (e) NB can be set to and only allow specific groups of users to insert.These are allowed to be called as CSG (Closed SubscriberGroup by the groups of users that H (e) NB inserts, limit groups of users), only allow the resident sub-district of CSG to become the CSG sub-district, each CSG sub-district is at affiliated PLMN (Public Land Mobile-communication Network, the public land mobile radio communication) all has unique CSG ID (Closed Subscriber Group Indicator limits user's group id) under.For a terminal, can add a plurality of CSG sub-district, therefore, on the HSS under terminal and this terminal, all can safeguard 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.The deployment of CSG list server shown in Fig. 1 or Fig. 2 then is optionally, is used to network to upgrade ACL when UE is registered in the network, and described HSS can occur to the subscription data of UE on the described MME.Like this, in the prior art, described MME is when setting up LIPA or SIPTO carrying for described UE, and whether the CSG ID of CSG sub-district that also needs to judge described UE place is on the ACL of described UE.If, could set up LIPA or SIPTO carrying for described UE, if not, then can not set up LIPA or SIPTO carrying for described UE.

Yet, not all base station, for example H (e) NB has the ability as the IP outlet.If the base station does not have this ability, even if then it allows described UE to carry out LIPA or SIPTO business, and the CSG ID of the CSG sub-district at described UE place is also on the ACL of described UE, be that core net is that described UE has set up LIPA or SIPTO carrying, described UE still can not use LIPA or SIPTO business.Like this, just may cause the waste of resources of core network.

In the following examples, except occurring in attaching process with LIPA or SIPTO access control is example, illustrate outside the method for the disclosed local IP access control of the embodiment of the invention, also the method for top embodiment is improved, with the described problem that may waste resources of core network of further solution.

Base station local maintenance LIPA or SIPTO allow member's tabulation, and this tabulation can be with representing as LIPA or SIPTO Member List.Be deployed with IAD in the network, this tabulation also can be maintained in this locality of IAD.Wherein the generating mode that should tabulate can repeat no more with reference to the appropriate section in the preamble for example herein.

Further, also safeguard the LIPA or the SIPTO capability indication information of this base station or IAD in the local context of base station or IAD.Described LIPA or SIPTO capability indication information are used to indicate described base station or IAD to have the ability of IP outlet.Concrete, can increase the capability indication information that LIPA or SIPTO are supported in this base station in base station radio access capability (the MS Radio Access Capability) field in base station context, described LIPA or SIPTO capability indication information for example can be LBO (Local Breakout, local breakout) Indication.

In the base station or IAD dispose under the scene of above-mentioned information, UE can initiate the carrying request of setting up of LIPA or SIPTO.Concrete, in the present embodiment, as an example, the LIPA of UE or SIPTO carrying can be adopted any one realization in the following dual mode.

Mode one: core net is that the UE that is allowed to carry out LIPA or SIPTO business directly sets up LIPA or SIPTO carrying, specifically can be with reference to Fig. 4.

Step 401, UE initiate Attach Request message and give the base station, if be deployed with IAD in the networking, then described base station is transmitted to described IAD with described Attach Request message.Described Attach Request message can be an Attach Request message, carries IMSI or the MSISDN of described UE in the described Attach Request message.

Step 402, described base station or IAD are transmitted the described Attach Request message of described UE to MME.Carry described base station or access gateway address in the described Attach Request message, as H (e) NB ID or H (e) NB-GW ID.

And, LIPA or SIPTO access control that described base station or IAD carry out UE according to described IMSI or the MSISDN of described UE.If the IMSI of described UE or MSISDN in described LIPA or SIPTO Member List, then allow described UE to carry out LIPA or SIPTO business.

Further, described base station or IAD, described base station or IAD will judge also whether LIPA or SIPTO capability indication information are arranged in its local context.If allow described UE to carry out LIPA or SIPTO business, and safeguard on described base station or the IAD LIPA or SIPTO capability indication information are arranged, as LBO Indication, then also send LIPA or SIPTO affirmation indication to described MME, this indication is used to indicate it to insert for described UE provides LIPA or SIPTO, and allow described UE to insert with LIPA or SIPTO mode, concrete, can be with representing as LIPA or SIPTO Indication.When MME sends, described LIPA or SIPTO Indication can be carried at arbitrarily and send in the S 1-MME signaling.In the UMTS system, then be to send to SGSN, described LIPA or SIPTOIndication can be carried at arbitrarily and send in the Iu-ps signaling this moment.

Step 403, described MME check that the CSG ID of the CSG sub-district that current described UE request inserts is whether in the ACL of described UE, if described CSG ID is in the ACL of described UE, and LIPA or SIPTO Indication information are arranged in the S1-MME signaling, then set up LIPA or SIPTO carrying for described UE.Described MME is according to LIPA or SIPTO APN and the base station or the access gateway address at described UE place, and the local PDN GW for described UE selects its base station, place or IAD hereinafter is called L-PGW.As previously mentioned, in the UMTS system, described L-PGW is L-GGSN accordingly.

In the EPS system, described MME further sets up the default bearer request message to the S-GW and the transmission of correspondence.The described default bearer request message of setting up can be a Create Default Bearer Request message, perhaps sets up conversation request message Create Session Request message.

Step 404, described S-GW create an inlet, and set up the default bearer request message to described L-PGW transmission in its EPS (Evolved Packet System, evolved packet system) carrying tabulation.The described default bearer request message of setting up can be a Create Default Bearer Request message, perhaps sets up conversation request message Create Session Request message.In the UMTS system,, then carry out this step by SGSN because the corresponding function of S-GW also has SGSN to carry out.

Step 405, described L-PGW return to described S-GW and set up the default bearer response message.The described default bearer response message of setting up can be a Create Default Bearer Response message, perhaps sets up conversational response message Create Session Response message.

Step 406, described S-GW return to described MME and set up the default bearer response message.Understandable, in the UMTS system, this step is omitted.

Step 407, described MME are returned initial context to described base station or IAD and are set up and ask/adhere to accept message and give base station or IAD.Described initial context is set up request message/adhere to, and to accept message can be Initial Context Setup Request/Attach Accept message.

Step 408, described base station or IAD send Radio Resource to described UE and connect reconfiguration message.Described wireless resource control connection reconfiguration message can be RRC Connection Reconfiguration message.

Afterwards, network can be carried out other attachment flow.For example specifically can be with reference to the attachment flow that defines in the 23.401v9.0.0 agreement.The GPRS that the universal terrestrial access network that described 23.401 agreements are evolution inserts strengthens agreement.

Mode two: core net is that the UE that is allowed to carry out LIPA or SIPTO business issues LIPA or SIPTO indication, receives that the UE of indication can follow-up initiations LIPA or SIPTO business, sets up LIPA or SIPTO and carries.Specifically can be with reference to Fig. 5.

Step 501 is identical to step 402 with step 401 to step 502, specifically can repeat no more with reference to description above herein.

Step 503, MME check that the CSG ID of the CSG sub-district that current described UE request inserts is whether in the ACL of described UE, if described CSG ID is in the ACL of described UE, and LIPA or SIPTO Indication information are arranged in the S1-MME signaling, then send and set up the default bearer request message to the S-GW of correspondence.The described default bearer request message of setting up can be a Create Default Bearer Request message, perhaps sets up conversation request message Create Session Request message.

Step 504 is identical to step 406 with step 404 to step 506, repeats no more herein.

Step 507, described MME send initial context foundation and ask/adhere to accept message to base station or IAD, carry LIPA or SIPTO Allowed indication in this message.Described LIPA or SIPTOAllowed are designated as LIPA or SIPTO allows indication, represents that after this described UE can rely on this information directly to ask to set up carrying.Described initial context is set up request message/adhere to, and to accept message can be InitialContext Setup Request/Attach Accept message.

Step 508, described base station or IAD send Radio Resource to described UE and connect reconfiguration message, carry described LIPA or SIPTO Allowed indication in this message.Described wireless resource control connection reconfiguration message can be RRC Connection Reconfiguration message.

Described UE can initiate LIPA or SIPTO service request according to described LIPA or SIPTO Allowed indication is follow-up, and core net can be set up LIPA or SIPTO carrying for described UE.Concrete, the method for building up of described LIPA or SIPTO carrying can be with reference to the description in figure 4 and the aforesaid way one.Different is that in the step 401, described UE carries described LIPA or SIPTO Allowed in described adhering in the request; In the step 402, described base station or IAD directly send to MME with described described LIPA or the SIPTOAllowed that adheres in the request.In step 403, described MME directly is that described UE sets up carrying according to described LIPA or SIPTOAllowed.

In foregoing invention embodiment, base station or IAD local maintenance LIPA or SIPTO allow member's tabulation, and UE initiates Attach Request message and gives described base station or described IAD, carries IMSI or the MSISDN of described UE in the described Attach Request message.If the described IMSI of described UE or MSISDN allow then to allow described UE to carry out LIPA or SIPTO business in member's tabulation at the LIPA or the SIPTO of described base station or IAD local maintenance.Further, in the local context of described base station or IAD, also safeguard the LIPA or the SIPTO capability indication information of this base station or IAD.If described UE is allowed to carry out LIPA or SIPTO business, and safeguard in the local context of described base station or IAD LIPA or SIPTO capability indication information are arranged, then send LIPA or SIPTO affirmation indication LIPA or SIPTOIndication to MME, by described MME is that described UE sets up LIPA or SIPTO carrying, perhaps described LIPA or SIPTOIndication are handed down to described UE, initiate the LIPA carrying by described LIPA of the follow-up use of described UE or SIPTOIndication and set up request.Like this, when LIPA or SIPTO business were carried out in the UE request, system all took resources of core network at every turn when need not to enter control, but finished access or SIPTO control by base station or IAD, had improved the execution efficient of system.Further, only in described base station or IAD when possessing LIPA or SIPTO export capacity, core net is just set up LIPA or SIPTO carrying for described UE, effectively reduces the wasting of resources of core net.

Disclosed method among the ensuing embodiment is specifically finished the affirmation of LIPA or SIPTO business by MME.This method goes for the Fig. 1 or the network architecture shown in Figure 2.Wherein, IAD is optional.

Also safeguard the LIPA or the SIPTO capability indication information of this base station or IAD in the local context of base station or IAD.Described LIPA or SIPTO capability indication information are used to indicate described base station or IAD to have the ability of the outlet that inserts as local IP.Concrete, can increase the capability indication information that LIPA or SIPTO are supported in this base station in base station radio access capability (the MS Radio Access Capability) field in base station context, described LIPA or SIPTO capability indication information for example can be LBO (Local Breakout, local breakout) Indication.

Mode one: core net is that the UE that is allowed to carry out LIPA or SIPTO business directly sets up LIPA or SIPTO carrying, specifically can be with reference to Fig. 6.

Step 601, UE initiate Attach Request message and give the base station, if be deployed with IAD in the networking, then described base station is transmitted to described IAD with described Attach Request message.Described Attach Request message can be an Attach Request message, carries IMSI or the MSISDN of described UE in the described Attach Request message.
