Description

The improper network method that moves back of Home eNodeB

Technical field

The present invention relates to the communications field, improper (ungraceful) moves back network method in particular to a kind of Home eNodeB.

Background technology

For higher service rate being provided to the mobile subscriber and reducing the investment of using the needed expense of high rate services, reducing the carrier network deployment; simultaneously; in order to remedy the deficiency that existing distributed cellular radio communication system covers; usually can in existing communication network, dispose base station from home and (be also referred to as Home eNodeB; promptly; Femto or WFAP), as replenishing to macro base station.The base station from home operated by rotary motion is used in places such as family, Administrative Areas.Base station from home is a kind of small-sized, lower powered base station, has advantages such as practicality, convenient, low-power output.

Fig. 1 is according to the network architecture schematic diagram behind the deployment Home eNodeB of prior art, as shown in Figure 1, the first half in the drawings is the grand station network diagram of not disposing Home eNodeB, comprise: macro base station Access Network (Macro Access Service Network, abbreviate MacroASN as), core net (Connection Service Network abbreviates CSN as), wherein, Macro ASN comprises: macro base station (Base Station abbreviates BS as) and Access Network gateway (ASN-GW); CSN comprises: authentication and authorization charging (Authentication, Authorization and Accounting abbreviate AAA as) server, home agent (HomeAgent abbreviates HA as).The latter half in the drawings is to dispose the network element that increases newly behind the Home eNodeB, comprise: Home eNodeB Access Network (Femto ASN), Home eNodeB core net, wherein, the Home eNodeB core net is the network element that home base station network service provider (Femto NSP) provides.Femto ASN comprises: Home eNodeB IAD (Femto-GW, or abbreviation FeGW), self-organizing network server (Self Organization NetworkServer, abbreviate SON Server as), security gateway (Security Gateway abbreviates SeGW as); Network element among the Femto NSP comprises: the management system of Home eNodeB (WiMAXFemto Access Point Mgmt System, abbreviate WFAP Mgmt System as), Home eNodeB aaa server, Home eNodeB bootstrapping server (WFAP BootstrapServer).Need to prove that WFAP is identical with the Femto implication hereinafter, all be meant Home eNodeB.

In the network architecture behind above-mentioned deployment Home eNodeB, because Home eNodeB is by public network access to family base station network, the secure tunnel of SeGW and Home eNodeB (SecureTunnel) has guaranteed that Home eNodeB is linked into the fail safe of home base station network by public network.Femto-GW is as the IAD of Home eNodeB, and they exist data surface and chain of command passage, and after the Home eNodeB success initialization, when providing service for terminal, terminal all will be transmitted by Femto-GW to control signaling between the CSN and data.SON Server is mainly used to Home eNodeB is carried out the automatic configuration of MAC/PHY parameter, Automatic Optimal and self-fault-finding and recovery.It is the legal booking reader of this WFAP-NSP that WFAP-AAA is mainly used to authenticate the one family base station.WFAP-Mgmt System provides some upper-layer configured parameters except that MAC/PHY for Home eNodeB.

Fig. 2 is the Home eNodeB initialization flowchart according to correlation technique, comprises the steps:

On Home eNodeB, be provided with two types of parameters in advance: with the irrelevant parameter of operator, for example, the trusted certificate of Home eNodeB (WFAP-Credentials); The parameter relevant with operator, for example, the universe name of the Home eNodeB bootstrapping server that operator provides (Bootstrap Server) (Fully Qualified Domain Name abbreviates FQDN as).When Home eNodeB is linked into network, must find bootstrapping server, download initial parameter from bootstrapping server.Fig. 2 is the Home eNodeB initialization flowchart according to correlation technique, and the initialized detailed process of Home eNodeB comprises the steps:

Step 1, Home eNodeB is linked into broadband network, and the back bootstrapping powers on;

Step 2, Home eNodeB obtains its IP address (public network) by public network; If Home eNodeB does not have the FQDN of pre-configured bootstrapping server, this process also may be obtained the FQDN of bootstrapping server simultaneously;

Step 3 if Home eNodeB has only the FQDN of bootstrapping server, and does not have the IP address of bootstrapping server, and then Home eNodeB need pass through the IP address that domain name resolution server (DomainName System abbreviates DNS as) process is obtained bootstrapping server.

Step 4, Home eNodeB connects by setting up safety between pre-configured safety certificate and the bootstrapping server;

Step 5, Home eNodeB is connected to bootstrapping server, and the request initial configuration information.Home eNodeB provides its IP address and positional information (for example, GPS information etc.) to bootstrapping server, and the information that bootstrapping server provides according to Home eNodeB is selected a suitable SeGW.Bootstrapping server provides the IP address of SeGW to Home eNodeB, also provides management server WFAP Mgmt the FQDN of System simultaneously;

Step 6, secure tunnel between Home eNodeB foundation and the SeGW (SeGW distributes an Intranet IP address to Home eNodeB), and by SeGW and Femto-AAA contact, Femto-AAA finishes the authentication to Home eNodeB, that is, this Home eNodeB is the validated user of FemtoNSP;

Step 7, Home eNodeB are obtained the IP address of WFAP Mgmt System (being also referred to as Management Server) by DNS;

Step 8, Home eNodeB are connected to WFAP Mgmt System, and Home eNodeB sends local information to management server, comprising: the IP address of WFAP, software and hardware version, positional information etc.Based on these local informations, management server provides Home eNodeB high level (on the MAC/PHY layer) configuration information, and these information comprise the IP address or the FQDN of SON server;

Step 9, if provide FQDN in step 8, then Home eNodeB also needs to obtain by DNS the IP address of SON server;

Step 10, Home eNodeB are connected to the SON server, and provide local information to the SON server, comprising the positional information of Home eNodeB.The SON server carries out location-authentication according to the positional information of Home eNodeB to Home eNodeB; Home eNodeB by location-authentication could be launched wireless signal in certain frequency range or frequency range.The SON server also can provide MAC/PHY layer configuration parameter to Home eNodeB.

Step 11, Home eNodeB is registered on Femto-GW; Be included between Home eNodeB and the Femto-GW and set up data channel.

After above-mentioned steps, Home eNodeB enters operating state, can provide service for the terminal in its coverage.After the Home eNodeB initialization procedure is meant that Home eNodeB is linked into broadband connection (for example, DSL etc.) in a word, power on,, and can provide a series of processes of service to the user by authentication.

Initialization flow process by Home eNodeB as can be known, after Home eNodeB was finished initialization, a series of network elements in the network were all safeguarded the information of Home eNodeB.For example, in step 6, Home eNodeB and security gateway are set up secure tunnel, and be mutual by secure tunnel and Femto-AAA then, by authentication, so keeps a femtocell information by authentication among the Femto-AAA; In step 8, Home eNodeB and Mgmt System are mutual, obtain upper-layer configured information and SON server info, so Mgmt System have also obtained the information of this Home eNodeB; In step 10, Home eNodeB and SON Server are mutual, obtain information such as MAC/PHY/RF, and the SON server has also obtained the information of this Home eNodeB simultaneously; In step 11, set up data channel between Home eNodeB and the Femto-GW, so also safeguarded the information of this Home eNodeB among the Femto-GW.

From the above, in Home eNodeB initialization (or being called registration) process, chain of command network element (SON Server, Mgmt System), and chain of command network element (SeGW, FeGW, Femto-AAA) obtains the network element of femtocell information, behind registering family base station, all need resource or the information of safeguarding that some are relevant with this Home eNodeB, or carry out the certain operations relevant with this Home eNodeB, as described below respectively:

SON Server: safeguard this Home eNodeB and the station list information of this Home eNodeB as the adjacent area, and to these base station optimizing neighbor lists; To the wireless parameter of this Home eNodeB or receive that the wireless parameter of the base station of this Home eNodeB influence is optimized;

Mgmt Syteme: Home eNodeB management system.Safeguard the configuration information (for example CSG Info) and the renewal thereof of this base station family;

SeGW: security gateway.Safeguard the secure tunnel between SeGW and the Home eNodeB;

Femto-AAA: safeguard Home eNodeB state or charge information etc.;

FeGW: the contextual information when safeguarding this base station login.

As seen, when the family base station networks and successfully after the registration, above-mentioned these network elements all need some resources and the information of safeguarding that this Home eNodeB is relevant and some relevant actions.If because certain reason, Home eNodeB is unexpected and network is out of touch, can not normally be recovered for a long time; these network elements of network side so; comprise the chain of command network element (SON Server, MgmtSystem), chain of command network element (FeGW; SeGW; Femto-AAA), need make correct operation, for example delete the relevant resource of this Home eNodeB; deletion or upgrade the context of Home eNodeB brings wireless parameter to change to handle to the Home eNodeB that moves back net etc.

When the family base station occurs improperly when moving back net, above-mentioned these network elements should know that Home eNodeB moves back net, otherwise can cause following possible mistake:

The information of Home eNodeB adjacent area tabulation in the SON server maintenance network, if Home eNodeB is improper move back net after, in time do not notify the SON server, then cause the Neighboring Cell List in the network incorrect, can influence performance of handoffs.The SON server is carrying out some MAC/PHY/RF Parameter Optimization, if Home eNodeB is improper move back net after, in time do not notify the SON server, then may cause parameter optimisation procedure to be made mistakes.

Mgmt System is responsible for the maintenance and the renewal of the CSG configuration information of Home eNodeB, if Home eNodeB is improper move back net after, in time do not notify Mgmt System, then cause Mgmt System also can initiatively upgrade the configuration information of the Home eNodeB that moves back net, for example CSG configuration information etc.Have secure tunnel between SeGW and the Home eNodeB, if Home eNodeB is improper move back net after, SeGW is not in time notified, and then can not remove SeGW and inter-household secure tunnel, causes the wasting of resources.Femto-AAA preferably also can obtain notice in addition, so that obtain the relevant treatment of the real-time status of Home eNodeB or the aspect of chargeing.

But, do not provide Home eNodeB improper process of moving back net to occur in the correlation technique.That is, do not provide which network element can trigger the improper net flow process of moving back of Home eNodeB.In the prior art, if the improper net that moves back appears in Home eNodeB, then the wasting of resources can occur in the network, and various mistakes may occur.

Mgmt System carry out Home eNodeB move back net handle can comprise at least one of following: the Neighboring Cell List that upgrades the neighbor base station (being the base station of containing this Home eNodeB in the Neighboring Cell List) of this Home eNodeB; Mgmt System stops initiatively to upgrade the configuration information (as the CSG information about firms) of described Home eNodeB, and for example, the renewal that does not send the configuration information of described Home eNodeB and described configuration information is to this Home eNodeB; Mgmt System deletes described femtocell information; Mgmt System upgrades described Home eNodeB state information; Send a warning message.

Wherein, it is one of following that above-mentioned renewal Neighboring Cell List comprises at least: this Home eNodeB of deletion from Neighboring Cell List, perhaps upgrade the state of this Home eNodeB from Neighboring Cell List.

Survey situation for the chain of command network element, can notify the chain of command network element on the one hand, this is because may there be detection mechanism alone in chain of command and chain of command network element, so do not need chain of command network element notice chain of command network element; Another chain of command network element is also notified the chain of command network element simultaneously.

Description control veil unit and chain of command network element detect the improper processing of moving back behind the net of Home eNodeB respectively below by different scenes.

Scene one, the improper net that moves back of Home eNodeB that FeGW triggers.

(for example move back net for the Home eNodeB of FeGW triggering is improper, detect the improper net that moves back of Home eNodeB by the handshake mechanism between FeGW and the Home eNodeB), the net that moves back that FeGW notifies SeGW to carry out Home eNodeB is handled, and SeGW notice Femto-AAA moves back the net processing.

Fig. 3 is the improper flow chart that moves back net of FeGW triggering Home eNodeB according to the embodiment of the invention, and as shown in Figure 3, this flow process comprises the steps:

Wherein the FeGW notice SeGW net that moves back that carries out the base station is handled and is comprised following two steps:

Step S301, FeGW detects the improper net that moves back of Home eNodeB, the request message that moves back net information that transmission carries Home eNodeB to SeGW (for example, adopt message WFAPNetExit Request), wherein, carry in the message of transmission following one of at least: the Home eNodeB sign of moving back net is (for example, the IP address of Home eNodeB, MAC Address, the perhaps sign of IEEE definition etc.), Home eNodeB moves back the type of net, and Home eNodeB moves back the reason of net.

Preferably, in this step, after FeGW detected that Home eNodeB is improper and moves back net, FeGW also can carry out the aforementioned net that moves back to Home eNodeB to be handled.

Step S302, SeGW receive moving back after the net information of Home eNodeB that FeGW sends, send response message (for example, adopting message WFAP NetExitResponse) to FeGW.

In this step, SeGW also needs to delete secure tunnel between itself and the Home eNodeB (as, ipsec tunnel).SeGW also needs to notify Femto-AAA that the improper net that moves back of Home eNodeB is handled.This process comprises following two steps:

Step S303, SeGW receive moving back after the net information of Home eNodeB that FeGW sends, send the message of moving back net information (for example, adopting message Account Request (Stop)) that carries this Home eNodeB to Femto-AAA.Wherein, carry in this message following one of at least: move back the Home eNodeB sign of net, Home eNodeB moves back the type of net, and Home eNodeB moves back the reason of net.

Step S304, Femto-AAA receive moving back after the net information of Home eNodeB that SeGW sends, and Femto-AAA responds the response message (for example, adopting message Account Response (Stop)) that Home eNodeB moves back net to SeGW.

In above-mentioned steps, step S303 occurs in after the step S301, the branch of step S303, the order with step S302 on not free.

Preferably, after FeGW detected that Home eNodeB is improper and moves back net, FeGW also can carry out the net that moves back of aforementioned Home eNodeB to be handled.Need to prove, FeGW carry out Home eNodeB move back net handle occur in FeGW and detect that Home eNodeB is improper and move back net after, the branch of the order with step S301, step S302, step S303 on not free, for example, can occur in before the step 301, before the step 302 or after the step 302.

Preferably, after SeGW received the message that FeGW sends, SeGW also can carry out the net that moves back of aforementioned Home eNodeB to be handled.

Preferably, after Femto-AAA received the message of SeGW transmission, Femto-AAA also can carry out the net that moves back of aforementioned Home eNodeB to be handled.

Scene two, the improper net that moves back of Home eNodeB that SeGW triggers.

For the improper net (for example, the improper net that moves back of the expired triggering Home eNodeB of the secure tunnel between SeGW and the Home eNodeB) that moves back of Home eNodeB that SeGW triggers, SeGW will notify FeGW and Femto-AAA respectively, handles so that they carry out the net that moves back of Home eNodeB.Fig. 4 is the improper net flow chart that moves back of SeGW triggering Home eNodeB according to the embodiment of the invention, and as shown in the figure, this flow process comprises the steps:

Wherein, SeGW notice FeGW handles the improper net that moves back of Home eNodeB.This process comprises following two steps:

Step S401, SeGW sends and to FeGW (for example to carry request message that Home eNodeB moves back net information, adopt message WFAP NetExit Request), wherein, this message carry following one of at least: the Home eNodeB sign of moving back net, Home eNodeB moves back the type of net, and Home eNodeB moves back the reason of net.

Step S402, FeGW receive after the information of SeGW transmission, send response message (for example, adopting message WFAP NetExit Response) to SeGW.

SeGW notice Femto-AAA handles the improper net that moves back of Home eNodeB.This process comprises following two steps:

Step S403, SeGW to Femto-AAA send carry Home eNodeB the message of moving back net information (for example, adopt message Account Request (Stop)), wherein, carry in this message following one of at least: the Home eNodeB sign of moving back net, Home eNodeB moves back the type of net, and Home eNodeB moves back the reason of net.

Step S404, Femto-AAA receive SeGW and send moving back after the net information of Home eNodeB, and Femto-AAA responds family to SeGW and moves back the response message of net (for example, adopting message Account Response (Stop)).

In above-mentioned steps, SeGW notice FeGW and Femto-AAA do not have the branch of sequencing; Be the branch (comprising the generation that to walk abreast) of step S401, the step S403 order on not free, and step S402, step S404 are respectively as the response of step S401, step S403.

After SeGW detected that Home eNodeB is improper and moves back net, SeGW also can carry out the net that moves back of aforementioned Home eNodeB to be handled.

Receive the message of SeGW transmission as FeGW after, FeGW also can carry out the net that moves back of aforementioned Home eNodeB to be handled.

Receive the message of SeGW transmission as Femto-AAA after, Femto-AAA also can carry out the net that moves back of aforementioned Home eNodeB to be handled.

Scene three, Femto-AAA triggers the improper net that moves back of Home eNodeB

For the improper net (for example, Femto-AAA finds that the WFAP CAMEL-Subscription-Information is expired) that moves back of Home eNodeB that Femto-AAA triggers, notify SeGW and FeGW, so that they are handled the improper net that moves back of Home eNodeB.Fig. 5 is that as shown in Figure 5, this flow process comprises the steps: according to the improper net flow chart that moves back of Home eNodeB of the Femto-AAA triggering of the embodiment of the invention

Femto-AAA notifies the SeGW Home eNodeB to move back net, comprises following two steps:

Step S501, Femto-AAA send chain rupture message to SeGW and (when adopting the Radius agreement, are Discconnect Request message; When adopting Diameter, be Abort-Session-Request (ASR) Command), wherein, carry in this message following one of at least: move back the Home eNodeB sign of net, Home eNodeB moves back the type of net, and Home eNodeB moves back the reason of net.

Step S502, SeGW send chain rupture request responding message to Femto-AAA and (when adopting the Radius agreement, are Discconnect ACK or Disconnect NACK message; When adopting Diameter, be Abort-Session-Answer (ASR) Command).

Receive the chain rupture message of Femto-AAA transmission as SeGW after, subsequent process is consistent with the improper net flow process of moving back of Home eNodeB that SeGW triggers, promptly, step S503～step S506 is with the step S401 in the scene two～step S404, do not repeat them here, wherein in above-mentioned steps, step S503 occurs in after the step S501, the branch of step S503, the order with step S502 on not free.

In the foregoing description, SeGW sends Home eNodeB to Femto-AAA and moves back net information, and when adopting radius protocol between SeGW and the Femto-AAA, that uses its definition is used to ask the charging request message (Accounting-Request/Stop) that stops to charge; When adopting Diameter between SeGW and the Femto-AAA, then use the charging request message of its definition, (Accounting-Request, abbreviate ACR as) and/or session termination request message (Session-Termination-Request, abbreviate STR as), wherein ACR is used for asking to charge stopping, and STR is used for request and stops session.Can certainly adopt other message to show that Home eNodeB moves back net.

In the foregoing description, Femto-AAA sends Home eNodeB to SeGW and moves back the net response message, when adopting the Radius agreement is Accounting-Response (stop), when adopting Diameter, be Session-Termination-Response (STR) Commandand and/or Accounting-Response (ACR) Command.Can certainly adopt other message to show that Home eNodeB moves back the net response.

Above-mentioned three scenes all are after the chain of command network element detects that Home eNodeB is improper and moves back net, each other mutual of chain of command network element and move back the net handling process.Further, the chain of command network element also needs Home eNodeB is moved back that the chain of command network element is known by Netcom so that the chain of command network element moves back net accordingly to be handled, and can send Home eNodeB to the chain of command network element comprising Femto-AAA or FeGW and move back net information.

The Home eNodeB that triggers for FeGW moves back net (comprise and normally move back net and the improper net that moves back), and FeGW also needs to notify the network element of chain of command except the network element of notice chain of command (as described in the scene one); The process of notice chain of command network element is: FeGW one of at least sends Home eNodeB to SONServer, Mgmt System and moves back net information, for example, notifies the chain of command network element in the mode that sends alarm.Wherein, the Home eNodeB that directly triggers if not FeGW moves back net, then triggers for FeGW receives after other chain of command transmission Home eNodeB moves back net back information.FeGW notice chain of command network element moves back net to Home eNodeB and handles, and one of can be in the following way carries out:

Mode one: FeGW sends the net information of moving back of Home eNodeB one of in SON Server, Mgmt System, and of the net information of moving back who receives the Home eNodeB that FeGW sends among SON Server, the Mgmt System sends the net information of moving back of Home eNodeB to another.

Method two: FeGW sends the net information of moving back of Home eNodeB to SON Server and Mgmt System.
