Home eNodeB moves back network method

Technical field

The present invention relates to the communications field, move 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; be 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, obtain the network element of femtocell information, when net is moved back in the family base station, should know that Home eNodeB moves back net, otherwise can cause following possible mistake:
