Description
Technical field
The present invention relates to the wireless communication technique field, specifically, relate to a kind of method, femto gateway and mobile management entity of access control.
Background technology
Home eNodeB is a kind of small-sized low power base station; Private resource as private user is deployed in private sites such as family, group, company or school; Be connected to the core net of operator through wired access devices such as cable, DSL (Digital SubscriberLine, digital subscriber line) or optical fiber.The main effect of Home eNodeB is higher service rate to the user to be provided, and reduces and use the needed cost of high-rate service, and the covering that remedies existing distributed cellular wireless telecommunication system simultaneously is not enough.The advantage of Home eNodeB comprises: low-cost, easy to use (plug and play), low power output, saved operator and set up with the expense of base station maintenance, solve indoor coverage optimization etc.
In Long Term Evolution (Long Term Evolution is called for short LTE) system, the Home eNodeB of evolution is called as HeNB (Home Evolved NodeB).Fig. 1 is the network architecture sketch map of HeNB in the prior art.Terminal under the HeNB (User Equipment is called for short UE) is based on the Home eNodeB Access Network (Home Evloved NodeB Access Network is called for short HeNBAN) that existing air protocol inserts evolution.HeNBAN is made up of the femto gateway of HeNB and evolution (Home EvolvedNodeB Gateway is called for short HeNB GW); Wherein HeNB GW is optional network element.Only connect a sub-district under the HeNB.HeNB can be directly connected to the block core (Evolved Packet Core is called for short EPC) of evolution through the S1 interface; Wherein HeNB is connected to gateway (Serving Gateway is called for short S-GW) through S1-U interface, and HeNB is connected to mobile management entity (Mobility Management Entity is called for short MME) through S1-MME interface.HeNB also can be connected to EPC through HeNB GW; Wherein S1-U interface can terminate in HeNB GW, perhaps terminates in EPC, and S1-MME interface process HeNB GW is to EPC.
Function that HeNB supported and eNB basically identical.The major function of HeNB GW is: the S1 message that relaying UE is relevant, the S1 message that the non-UE that terminates is relevant is selected MME etc. for UE in attaching process.In addition, the Home eNodeB management system of the evolution among Fig. 1 (HeNB ManagementSystem is called for short HeMS) is carried out maintenance and management to HeNB; According to the requirement configuration and the control HeNB of operator, wherein most importantly for HeNB realizes configuration feature, the content of configuration comprises examining of positional information; The parameter of HeNB, the parameter of core net, wireless access network (Radio AccessNetwork; The parameter of parameter abbreviation RAN) and wireless frequency (Radio Frequency is called for short RF).The relevant function of safety in security gateway (Security Gateway the is called for short SeGW) network enabled.
HeNB only provides service for the specific user, has therefore introduced the notion of sealing member group (Closed SubscriberGroup is called for short CSG) and has carried out access control.Each HeNB has specific CSG attribute, comprises sealing member group id (CSG Identity is called for short CSG ID) and access module.Here defined three kinds of sub-district access modules (Cell Access Mode) for HeNB: sealing (Close) pattern, have only the sealing member composition person of corresponding C SG ID sign just can insert; Mix (Hybrid) pattern, allow all UE to insert, but have the sealing member composition person of corresponding C SG ID sign to enjoy higher priority; Open (Open) pattern allows all UE to insert.
Each UE can be signed in among one or more CSG, and the CSG of permission tabulation (AllowedCSG List is called for short ACL) has comprised the CSG ID of the CSG that the permission terminal can be inserted.UE and core net are preserved ACL respectively.For the CSG sub-district, MME carries out access control according to the CSG ID of Target cell and user's ACL.For hybrid sub-district (pattern of referring to an access is the sub-district of hybrid), HeNB also need preserve the member condition (membership status) that inserts UE and carry out member's checking (Membership verification).
Based on existing 3GPP (3
RdGeneration Partnership Project, third generation partner program) agreement, UE can switch between HeNB according to following two kinds of flow processs: based on the switching flow of S1 interface with based on the switching flow of direct X2 interface.
Fig. 2 is UE switching flow figure based on the S1 interface between HeNB.This switching flow is not only applicable to the source HeNB situation identical with the CSG ID of target HeNB, is applicable to the CSG ID condition of different of source HeNB and target HeNB yet.
Source HeNB has received the measurement report that UE sends; Wherein comprised cellular global identity (Cell Global Indentity is called for short CGI) in the measurement report, tracing area sign (Tracking AreaIndentity; Be called for short TAI), CSG ID and member's sign (Member Indication).Source HeNB makes whether switching the decision of UE to Target cell based on measurement report.If HeNB decision in source is switched UE to Target cell, source HeNB sends to switch and requires (HANDOVER REQUIRED) message to MME.Switch the CSG ID that requires to have comprised in the message Target cell, if Target cell is the hybrid sub-district, this switching requires message also to comprise the access module of Target cell.
After MME receives handoff request message, carry out access control based on the CSG subscription information of CSG ID that receives in this message and storage.If the access control failure, MME sends switching preparation failure (HANDOVER PREPARATION FAILURE) message and stops handoff procedure.If the access control success, MME sends handoff request (HANDOVER REQUEST) message and gives target HeNB so, and in this message, comprises the CSG ID of Target cell.When requiring to have carried the access module cell of sub-district in the message in switching when; MME also will be based on the identity that is linked into Target cell that the CSG subscription information of switching the CSG ID require to receive in the message and storage decides UE; Be that UE is linked into Target cell with member or right and wrong member identity, and in handoff request message, carry the CSG member condition.
The CSG ID of CSG ID that target HeNB relatively receives in handoff request message and Target cell broadcasting.When in the handoff request message that CSG ID and sub-district member condition all are being received; If the CSG ID that in handoff request message, receives is the same with the CSG ID of Target cell broadcasting; The value of the CSG member condition that in handoff request message, receives is " member "; Target HeNB provides QoS (Quality of Service, the service quality) service of member's identity so; If the CSG ID of CSG ID that in handoff request message, receives and Target cell broadcasting is different; Target HeNB provides the QoS service of non-member's identity, and in Handover Request Acknowledge (HANDOVER REQUESTACKNOWLEDGE) message, sends the CSG ID of real Target cell broadcasting.When in the handoff request message of having only CSGID being received; If the CSG ID of CSGID that in handoff request message, receives and Target cell broadcasting is different, target HeNB sends handoff failure (HANDOVER FAILURE) message that has the suitable reason value and gives MME; If the CSG ID that in handoff request message, receives is the same with the CSG ID of Target cell broadcasting, target HeNB sends switching request acknowledgement message and gives MME so.
Fig. 3 is UE switching flow figure based on direct X2 interface between HeNB.When source HeNB and target HeNB are connected same MME pool (MME pond); Permission based on the condition that X2 interface switches is: do not need MME to carry out access control; Promptly two have the CSG of identical CSG ID or the switching of hybrid minizone, and perhaps working as target HeNB is the open access module.For cell-of-origin and Target cell is the situation of CSG sub-district or hybrid sub-district; Source HeNB sets up the CSGID that carries the cell-of-origin in request (X2SETUP REQUEST) message at the X2 that sends to target HeNB, and target HeNB sets up the CSG ID that also comprises Target cell in response (X2SETUPRESPONSE) message at the X2 that sends to source HeNB simultaneously.The CSG ID of source HeNB contrast cell-of-origin and Target cell determines whether the X2 handoff request message of initiation source to Target cell.And if Target cell is the sub-district of hybrid, source HeNB will comprise the CSG member condition in handoff request message so.In addition, in order to use correct charging policy, after the switching completion based on X2 interface between the HeNB, target HeNB comprises the CSG ID and the sub-district access module of Target cell in sending to the path conversion request of MME (PATH SWITCHREQUEST) message.
Switching based on X2 interface between the HeNB has following advantage compared with the switching based on the S1 interface between the HeNB: reduced the core net signaling traffic load of (Core Network is called for short CN), also reduced the time delay that too much Signalling exchange causes simultaneously.But the switching based on direct X2 interface between the current HeNB only is confined to the source HeNB situation identical with the CSG ID of target HeNB.

Embodiment
The present invention proposes a kind of method of access control: when the X2 that between HeNB, passes through HeNB GW switched generation, access control is carried out at HeNB GW place, and was as shown in Figure 4, comprises the steps:
S10, HeNB GW obtain the CSGID that UE once inserted into the sub-district of merits and demerits from specific messages;
After S20, HeNB GW received X2 handoff request message, inserting successfully according to the information of Target cell with the UE that is obtained, the CSG ID of mistake sub-district carried out access control.
Among the step S10, said specific messages comprises: initial terminal message (the INITIAL UE MESSAGE) message of UE when initial access the, the handoff request message in the S1 handoff procedure, the path switching request information in the X2 handoff procedure.
Among the step S10, HeNB GW obtains from specific messages and writes down the CSG ID that UE once inserted into the sub-district of merits and demerits, further comprises:
HeNB GW can obtain through the specific messages in initial access process, S1 handoff procedure and the X2 handoff procedure and write down the CSG ID that UE once inserted into the sub-district of merits and demerits.
Among the step S20, HeNB GW carries out access control according to the historical information of the CSG ID that the information and the UE of Target cell inserted the sub-district, comprises following several kinds of sights:
If judge that Target cell is the close sub-district; And among the CSG ID of the sub-district that the UE that the CSG ID of Target cell writes down in HeNB GW once successfully inserted; HeNB GW allowance UE inserts and switches to Target cell so, then transmits X2 handoff request message and gives target HeNB.
If judge that Target cell is the close sub-district; And among the CSG ID of the sub-district that the UE that the CSG ID of Target cell does not write down in HeNB GW once successfully inserted; HeNB GW refusal UE inserts and switches to Target cell so, replys X2 switching preparation failed message and gives source HeNB.
If judge that Target cell is the hybrid sub-district; And among the CSG ID of the sub-district that the UE that the CSG ID of Target cell writes down in HeNB GW once successfully inserted; HeNB GW allowance UE inserts with member's identity and switches to Target cell so; Transmit X2 handoff request message to target HeNB, be transmitted to and carry in the X2 handoff request message of target HeNB that to indicate be member's CSG member condition cell.
If judge that Target cell is the hybrid sub-district; And among the CSG ID of the sub-district that the UE that the CSG ID of Target cell does not write down in HeNB GW once successfully inserted; HeNB GW allowance UE inserts with non-member's identity and switches to Target cell so; Transmit X2 handoff request message to target HeNB, be transmitted in the X2 handoff request message of target HeNB and carry the CSG member condition cell of indicating non-member.
The present invention further proposes, and after HeNB GW place carries out access control, can also carry out the affirmation of access control again at MME, comprises following several kinds of sights:
If it is the close sub-district that MME judges Target cell, and HeNB GW place inserts in the CSG subscription information that successful CSGID stores in MME, and then MME allowance UE access switches to Target cell, return path conversion request acknowledge message.
If MME judges that Target cell is the close sub-district; And in the CSG subscription information that the successful CSG ID of access of HeNB GW place does not store in MME; Then MME refusal UE inserts and switches to Target cell; Return path conversion request failed message is given HeNB GW, makes the historical information of CSG ID of the sub-district that the UE of its record once successfully inserted that HeNB GW upgrades in time.
If MME judges that Target cell is the hybrid sub-district; And at HeNB GW place during access control; UE can be linked into Target cell with member's identity; In the CSG subscription information that the successful CSG ID of access of HeNB GW place stores in MME, MME allowance UE inserts with member's identity and switches to Target cell, return path conversion request acknowledge message so.
If MME judges that Target cell is the hybrid sub-district; And at HeNB GW place during access control; UE can be linked into Target cell with member's identity, and in the CSG subscription information that the successful CSG ID of access of HeNB GW place does not store in MME, MME allowance UE inserts with non-member's identity and switches to Target cell so; Return path conversion request failed message; Carry indication CSG ID invalid cause value cell, thereby make MME that this this CSG ID is informed HeNB GW, upgrade in time the historical information of CSG ID of the sub-district that the UE of its record once successfully inserted of HeNB GW.
The CSG ID that once successfully inserted the sub-district as HeNB GW accumulation UE is time to a certain degree, and access control carries out improving greatly the efficient of the switching of the X2 interface that passes through HeNB GW between the different CSG sub-district at HeNB GW place.
For making the object of the invention, technical scheme and advantage clearer, hereinafter will combine accompanying drawing that embodiments of the invention are elaborated.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.
Fig. 5 is the flow chart of method of the access control of the embodiment of the invention, and is as shown in Figure 5, comprises following step:
Step 101, HeNB GW through initial insert, S1 switches and the specific messages of X2 in switching, and obtains and write down the CSG ID of the sub-district that UE once successfully inserted.
HeNB GW can obtain and write down the CSG ID of the sub-district that UE once successfully inserted from following specific messages:
One, HeNB GW obtains and writes down the CSG ID of the sub-district that UE once successfully inserted in the UE initial access process, and detailed process is following:
UE sends RRC connection request (RRC CONNEC TION REQUEST) message and gives HeNB, and HeNB replys RRC connection foundation (RRC CONNECTION SETUP) message and gives UE, and UE replys RRC and connects completion (RRC CONNECTION COMPLETE) message to HeNB.Above-mentioned RRC connects and sets up process and transmitted the initial NAS from UE to HeNB (Non AccessStatum, Non-Access Stratum) specific messages, i.e. attach request (ATTACH REQUEST) message has been initiated the process of initial access.
When HeNB receive from eating dishes without rice or wine be transmitted in the RRC connection and will be forwarded to first up NAS message (being Attach Request message) of MME after; HeNB sends initial terminal message to HeNBGW; Wherein Attach Request message is as the NAS-PDU in the initial terminal message (Protocol DataUnit, protocol Data Unit) cell.HeNB GW is forwarded to MME after receiving initial terminal message.
If be based upon between UE and the CSG sub-district because RRC connects, the CSG ID of the sub-district of UE access will be included in the initial terminal message so.If be based upon between UE and the hybrid sub-district because RRC connects, the CSG ID of the sub-district of inserting so and the access module of sub-district will be included in the initial terminal message.
Therefore, HeNB GW through the CSG ID cell in the initial terminal message, can obtain and write down the CSG ID of the sub-district that UE once successfully inserted in initial access process.
Two, HeNB GW obtains and writes down the CSG ID of the sub-district that UE once successfully inserted in the S1 handoff procedure, and detailed process is following:
Source HeNB sends to switch and requires message to give MME.When the access module of Target cell is close, switch to require message to comprise the CSG ID of Target cell.When the access module of Target cell was hybrid, handoff request message was drawn together the CSG ID of Target cell and the access module of Target cell.
MME carries out access control after requiring message receiving to switch.If Target cell is the CSG sub-district, MME is based on the CSG ID that switches the Target cell require to receive in the message and carries out the access control of UE with the CSG subscription information of storage, if the access control success, MME transmission handoff request message is to target HeNB so.Wherein, comprised in the handoff request message switch require Target cell in the message CSG ID.If the access control failure, MME sends switching preparation failed message and stops handoff procedure for source HeNB.If Target cell is the hybrid sub-district; MME is based on the CSG ID that switches the Target cell require to receive in the message and the CSG subscription information of storage is carried out the access control of UE; If in the CSG subscription information that the CSG ID that switching requires Target cell in the message is storing; UE can insert Target cell with member's identity so, and MME sends handoff request message to target HeNB; If in the CSG subscription information that the CSG ID that switching requires Target cell in the message is not storing, UE can insert Target cell with non-member's identity so, and MME sends handoff request message to target HeNB.At this moment, both comprised in the handoff request message and switched the CSG ID that requires Target cell in the message, also comprised the CSG member condition of indicating non-member.
MME sends handoff request message, after HeNB GW receives this message, forwards the message to target HeNB.
Therefore, HeNB GW is in the S1 handoff procedure, if Target cell is the close sub-district, so through the CSG ID cell in the handoff request message, just can obtain and write down the CSG ID of the sub-district that UE once successfully inserted; If target is the hybrid sub-district,, just can obtain and write down the CSG ID of the sub-district of the mistake that UE once successfully inserted with member condition so through CSG ID cell and member condition cell in the handoff request message.
Three, HeNB GW obtains and writes down the CSG ID of the sub-district that UE once successfully inserted in the X2 handoff procedure, and detailed process is following:
When switching based on direct X2 interface between the HeNB, source HeNB sends X2 handoff request message and gives target HeNB, and target HeNB sets up necessary resource for the switching of coming in, and replys switching request acknowledgement message and gives source HeNB.After UE successfully switched to Target cell, target HeNB transmit path conversion request message was given MME.Under the situation that HeNB GW exists, target HeNB sends this message to HeNB GW, and HeNB GW transmits this message and gives MME.The CSG ID that comprises the Target cell that the UE successful switch arrives in the path switching request information.
Therefore, when HeNB GW switches based on direct X2 interface,, just can obtain and write down the CSD ID of the sub-district that UE once successfully inserted between HeNB through the CSG ID cell in the path switching request information.
When the X2 that passes through HeNB GW between the HeNB switched, source HeNB sent X2 handoff request message and gives HeNB GW, and HeNB GW transmits this message to target HeNB.Target HeNB sets up necessary resource for the switching of coming in, and replys switching request acknowledgement message and gives HeNB GW, and HeNB GW transmits this message to source HeNB.After UE successfully switched to Target cell, target HeNB transmit path conversion request message was to HeNB GW, and HeNB GW transmits this message and gives MME.The CSG ID that comprises the Target cell that the UE successful switch arrives in the path switching request information.
Therefore, HeNB GW is when the X2 through HeNB GW switches between HeNB, through the CSG ID cell in the path switching request information, just can obtain and write down the CSG ID of the sub-district that UE once successfully inserted.
Step 102, when the X2 through HeNB GW switches between the HeNB, the historical information execution access control of the CSG ID of the sub-district that HeNB GW inserted according to the information and the UE of Target cell.
In initial the access,, in initial terminal message, just carry CSG ID cell so if HeNB is close or hybrid.Under the situation that HeNB GW exists, initial terminal message sends to HeNB GW by HeNB, is forwarded to MME by HeNB GW again.Therefore, HeNB GW knows all CSG sub-districts that are connected below it and the CSG ID of hybrid sub-district.
When source HeNB sent X2 handoff request message to HeNB GW, HeNB GW can learn the CSG ID of target HeNB from the sub-district overall identification (E-UTRAN Cell Global Identifier is called for short ECGI) of the Target cell the handoff request message.So, the historical information of the CSG ID of the sub-district that HeNB GW successfully inserted according to the UE that obtains in the step 101 and write down is carried out access control.
When Target cell was the close sub-district, if among the CSG ID of the sub-district that the CSG ID of Target cell is the UE that writes down among the HeNB GW once successfully to be inserted one, HeNB GW transmitted this X2 handoff request message to target HeNB so; If among the CSG ID of the sub-district that the UE that the CSG ID of Target cell does not write down in HeNB GW once successfully inserted, HeNB GW directly replys the X2 switching and prepares failed message to source HeNB so, stops handoff procedure.
When having comprised the cell of sub-district access module in the X2 handoff request message; Promptly when Target cell is the sub-district of hybrid; If among the CSG ID of the sub-district that the UE that the CSG ID of Target cell does not write down in HeNB GW once successfully inserted; UE can insert Target cell with non-member's identity so, and HeNB GW transmits X2 handoff request message to target HeNB; If among the CSG ID of the sub-district that the UE that the CSG ID of Target cell writes down in HeNB GW once successfully inserted, UE can insert Target cell with member's identity so, and HeNB GW transmits X2 handoff request message to target HeNB.Therefore, when sub-district access module cell existed in handoff request message, HeNB GW decision UE switched to the member condition of hybrid sub-district, and X2 handoff request message also comprises CSG member condition cell.
Step 103, after UE and Target cell successful execution X2 switching, MME carries out access control and confirms.
Consider that UE arrives the signatory possible overdue situation of some CSG sub-district; MME will be based on the CSG subscription information that stores among CSG ID and the MME of the Target cell that receives in the path switching request information and carry out access control once more, and the result who promptly HeNB GW place is carried out access control confirms.
When MME judges that Target cell is the close sub-district; If in the CSG subscription information corresponding that the CSG ID of the successful Target cell of HeNB GW place access does not store in MME with said UE; MME informs HeNB GW through suitable cause value (for example, invalid CSG ID) with the CSG ID of this Target cell in the conversion request failed message of path so.HeNB GW after receiving this message, the historical information of the CSG ID of the sub-district that the UE of its record that upgrades in time once successfully inserted.If in the CSG subscription information that the successful CSG ID of access of HeNB GW place stores in MME, MME gives HeNB GW in reverse-path conversion request acknowledge message so, HeNB GW forwards the message to target HeNB.
