Description

Abnormal network quitting method for home base station

Technical Field

The invention relates to the field of communication, in particular to a method for abnormal (unlicensed) network quitting of a home base station.

Background

In order to provide higher traffic rates to mobile users and reduce the cost required for using high-rate services, reduce the investment in operator network deployment, and at the same time, to make up for the lack of coverage of existing distributed cellular wireless communication systems, home base stations (also called home base stations, i.e., femtos or WFAPs) are often deployed in existing communication networks as a supplement to macro base stations. Home base stations are generally installed in homes, office areas, and the like. The home base station is a small-sized and low-power base station, and has the advantages of practicability, convenience, low power output and the like.

Fig. 1 is a schematic diagram of a network architecture after a home base station is deployed according to the prior art, and as shown in fig. 1, a schematic diagram of a macro-station network without a home base station deployed in the upper half of the figure includes: a macro base station access network (macro access service network, abbreviated as macro asn), and a core network (connectivity service network, abbreviated as CSN), wherein the macro asn includes: a macro Base Station (BS) and an access network gateway (ASN-GW); the CSN comprises: authentication, authorization and accounting (AAA) server and home agent (home agent, HA). The lower half of the figure is a network element newly added after the femtocell is deployed, and the network element comprises: a home base station access network (femtoASN), and a home base station core network, wherein the home base station core network is a network element provided by a home base station network service provider (femtonSP). The femtosn includes: a Femto access gateway (Femto-GW, or simply referred to as FeGW), a self-organizing network server (self organizing network server, simply referred to as SONServer), and a security gateway (secure gateway, simply referred to as SeGW); the network element in the FemtoNSP comprises: a management system of the home base station (wimaxfemotocesspointmgmtsystem, WFAPMgmtSystem for short), a home base station AAA server, and a home base station bootstrap server (wfapboottrapserver). It should be noted that WFAP and Femto in the following are the same and refer to home base station.

In the network architecture after the femtocell is deployed, since the femtocell is accessed to the femtocell network through the public network, the security of the femtocell network accessed to the femtocell network through the public network is ensured by the security tunnel (securettunnel) of the SeGW and the femtocell. Femto-GW is used as an access gateway of the home base station, data plane and control plane channels exist in the Femto-GW, and after the home base station is initialized successfully and provides service for the terminal, control signaling and data between the terminal and the CSN are forwarded through the Femto-GW. The SONServer is mainly used for carrying out automatic configuration, automatic optimization and self-fault detection and recovery on MAC/PHY parameters of the home base station. WFAP-AAA is mainly used to authenticate that a home base station is a legal subscriber of the WFAP-NSP. The WFAP-MgmtSystemA provides the home base station with some upper layer configuration parameters besides the MAC/PHY.

Fig. 2 is a flowchart of home base station initialization according to the related art, including the steps of:

two types of parameters are configured in advance on the home base station: operator independent parameters, such as trust certificates for home base stations (WFAP-credits); operator-related parameters, such as the full domain name (FQDN) of the home base station bootstrap server (boottrapserver) provided by the operator. When the home base station accesses the network, the home base station must discover the bootstrap server and download the initial parameters from the bootstrap server. Fig. 2 is a flowchart of home base station initialization according to the related art, and a detailed procedure of home base station initialization includes the following steps:

step 1, a home base station is accessed to a broadband network and bootstrapped after being electrified;

step 2, the home base station acquires the IP address (public network) thereof through the public network; if the femtocell does not pre-configure the FQDN of the bootstrap server, the process may also acquire the FQDN of the bootstrap server at the same time;

step 3, if the femtocell only has the FQDN of the bootstrap server and does not have the IP address of the bootstrap server, the femtocell needs to acquire the IP address of the bootstrap server through a domain name resolution server (domain name system, abbreviated as DNS) process.

Step 4, the home base station establishes a secure connection with the bootstrap server through a pre-configured security certificate;

and step 5, the home base station is connected to the bootstrap server and requests initial configuration information. The femtocell provides its IP address and location information (e.g., GPS information, etc.) to the bootstrap server, and the bootstrap server selects an appropriate SeGW according to the information provided by the femtocell. The bootstrap server provides the IP address of the SeGW for the home base station, and also provides the FQDN of the WFAPMgmtSystems of the management server;

step 6, the home base station establishes a security tunnel with the SeGW (the SeGW allocates an intranet IP address to the home base station), and the Femto-AAA completes authentication of the home base station through the contact between the SeGW and the Femto-AAA, namely, the home base station is a legal user of the Femto NSP;

step 7, the home base station acquires an IP address of a WFAPMgmtSystemP (also called a management Server) through a DNS;

step 8, the home base station is connected to the WFAPMgmtSystem, and the home base station sends local information to the management server, including: IP address, software and hardware version, location information of WFAP, etc. Based on this local information, the management server provides home base station high-level (above MAC/PHY) configuration information including the IP address or FQDN of the SON server;

step 9, if the FQDN is provided in step 8, the home base station further needs to acquire the IP address of the SON server through DNS;

and step 10, the home base station is connected to the SON server and provides local information to the SON server, wherein the local information comprises the position information of the home base station. The SON server carries out position authentication on the home base station according to the position information of the home base station; the home base station that passes the location authentication can transmit wireless signals in a certain frequency band or frequency range. The SON server also provides MAC/PHY layer configuration parameters to the home base station.

Step 11, registering the home base station on Femto-GW; the method comprises the step of establishing a data channel between the home base station and the Femto-GW.

After the above steps, the femtocell enters an operating state, and can provide services for the terminals within the coverage area of the femtocell. In short, the home base station initialization process refers to a series of processes in which, after the home base station is connected to a broadband connection (e.g., DSL, etc.), the home base station is powered on, passes authentication, and can provide services to a user.

Through the initialization process of the femtocell, after the femtocell completes initialization, a series of network elements in the network all maintain the information of the femtocell. For example, in step 6, the femtocell and the security gateway establish a security tunnel, and then interact with Femto-AAA through the security tunnel, and pass authentication, so that information of the femtocell passing authentication is maintained in Femto-AAA; in step 8, the femtocell interacts with the MgmtSystem to obtain upper layer configuration information and SON server information, so that the MgmtSystem also obtains the information of the femtocell; in step 10, the femtocell interacts with the SON server to obtain information such as MAC/PHY/RF, and the SON server also obtains information of the femtocell; in step 11, a data channel is established between the home base station and the Femto-GW, and therefore information of the home base station is also maintained in the Femto-GW.

As can be seen from the above, in the process of initializing (or called as registering) the home base station, the management plane network element (SONServer, MgmtSystem) and the control plane network element (SeGW, FeGW, Femto-AAA) acquire the home base station information, and after registering the home base station, some resources or information related to the home base station need to be maintained, or some operations related to the home base station need to be performed, which are respectively as follows:

SONServer: maintaining the information of a base station list of the home base station and taking the home base station as a neighbor cell, and optimizing the neighbor cell list of the base stations; optimizing the wireless parameters of the home base station or the wireless parameters of the base station influenced by the home base station;

MgmtSyteme: and a home base station management system. Maintaining configuration information (e.g., CSGInfo) and updates for the base station home;

SeGW: and a security gateway. Maintaining a secure tunnel between the SeGW and the femtocell;

Femto-AAA: maintaining the state of the home base station or charging information and the like;

FeGW: and maintaining the context information when the base station is registered.

It can be seen that, after the femtocell accesses the network and successfully registers, the network elements all need to maintain some resources and information related to the femtocell, and some related actions. If for some reason, the femtocell suddenly loses contact with the network and cannot be normally recovered for a long time, the network elements on the network side, including a management plane element (son server, MgmtSystem) and a control plane element (FeGW, SeGW, Femto-AAA), need to perform correct actions, such as deleting resources related to the femtocell, deleting or updating a context of the femtocell, and processing changes of wireless parameters brought by the femtocell that is going off the network.

When the home base station goes out of the network abnormally, the network elements should know that the home base station goes out of the network, otherwise, the following possible errors are caused:

the SON server maintains information of a neighbor list of the home base station in the network, and if the home base station is not notified to the SON server in time after being abnormally quitted, the neighbor list in the network is incorrect, and the switching performance is affected. The SON server performs optimization of some MAC/PHY/RF parameters, and if the home base station does not notify the SON server in time after abnormal network quit, an error may be caused in the parameter optimization process.

The MgmtSystem is responsible for maintaining and updating the CSG configuration information of the femtocell, and if the femtocell is not notified to the MgmtSystem in time after exiting the network abnormally, the MgmtSystem may also actively update the configuration information of the femtocell that has exited the network, such as the CSG configuration information. A safety tunnel exists between the SeGW and the home base station, and if the SeGW is not notified in time after the home base station quits the network abnormally, the safety tunnel between the SeGW and the home cannot be dismantled, so that resource waste is caused. Furthermore, Femto-AAA can also be informed to acquire the real-time status of home base station or to perform related processing in charging.

However, the related art does not provide a process for the femtocell to exit from the network abnormally. That is, which network elements can trigger the abnormal network exit procedure of the hnb are not provided. In the prior art, if the femtocell leaves the network abnormally, resource waste occurs in the network, and various errors may occur.

Disclosure of Invention

The main objective of the present invention is to provide an abnormal network exit method for a femtocell, so as to at least solve the problems of network resource waste and various errors that may occur due to the fact that an abnormal network exit procedure of the femtocell does not exist in the related art.

In order to achieve the above object, according to an aspect of the present invention, there is provided a method for a home base station to quit a network abnormally.

The abnormal network quitting method of the home base station comprises the following steps: one of the predetermined network elements sends a message to other predetermined network elements, wherein the predetermined network elements include at least one of: the home base station access gateway FeGW, the security gateway SeGW, the authentication authorization accounting server Femto-AAA, the self-organizing network server SONSever and the home base station management system MgmtSystemA.

By the invention, after the network elements (control plane network elements FeGW, SeGW, Femto-AAA, and management network elements SONServer, MgmtSystem) in the network detect that the home base station is abnormally withdrawn, the network withdrawal process of the abnormal home base station can be initiated, so that the problem that various errors can be caused by the fact that a complete abnormal network withdrawal process does not exist in the related technology is solved, the network withdrawal process is further improved, and the errors caused by the network withdrawal of the home base station are reduced.

Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In this embodiment, an abnormal network exit method for a home base station is provided, where the method includes: and the predetermined network element sends network quitting information of the home base station to at least one of the management plane network elements and/or at least one of the control plane network elements, wherein the predetermined network element is a network element which learns that the home base station abnormally quits the network.

Network elements in the network are divided into two parts: control plane network element and management plane network element, wherein, control plane network element includes: Femto-GW (FeGW for short), SeGW and Femto-AAA, wherein the management network element comprises: SONServer, MgmtSystems. After any network element of the control plane and the management plane detects that the femtocell exits from the network abnormally, the network exiting process of the abnormal femtocell can be initiated. That is, the network element that detects that the home base station exits from the normal hall notifies other network elements in the network, and the home base station exits from the normal hall, so that the other network elements (including the network element that detects that the home base station exits from the normal hall) perform corresponding processing on the abnormal exit of the home base station.

The following describes the present embodiment in terms of the control plane and the management plane, respectively.

Control surface

After detecting that the home base station is abnormally quitted, the control plane network element performs at least one of the following processes: and informing other network elements of the control plane so that other network elements of the control plane (including the control plane network element which detects abnormal network exit of the home base station) perform appropriate treatment on the abnormal network exit of the home base station. Since the abnormal network quitting processing of each control plane network element to the femtocell is not completely the same, the following description is respectively given:

the FeGW processes the abnormal quit-network home base station and comprises at least one of the following steps: deleting the context information of the home base station (the context information further comprises R6-F interface information); deleting a data channel between the home base station and the home base station; deleting the context information of the terminal served by the home base station; and triggering an abnormal network exit process of the terminal which obtains the service from the home base station.

The SeGW processing the abnormal quit network home base station comprises at least one of the following steps: the SeGW deletes the context information of the home base station; deleting a security tunnel established with the home base station (the security tunnel may also be deleted by the home base station, where, for example, the security tunnel is an IPSec tunnel), and since the home base station is not in a normal network exit, at this time, the SeGW may directly delete context information (e.g., security association information) used for establishing the security tunnel with the home base station, so as to release resources; and sending a message carrying the network quitting information of the home base station to Femto-AAA (for example, Accounting-request (stop) of home base station charging message).

Femto-AAA processing the abnormal quit network home base station comprises at least one of the following steps: Femto-AAA updates the state information of the home base station; home base station charging related processing (e.g. stopping charging to the home base station).

It should be noted that the abnormal network logout procedure triggered by the FeGW from the terminal served by the hnb is the same as the abnormal network logout procedure triggered by the ASN-GW in the existing NWG protocol.

For the situation that the control plane network element detects that the femtocell abnormally exits the network, on one hand, the management plane network element does not need to be notified, because the control plane and the management plane network element may have an independent detection mechanism, the management plane network element does not need to be notified by the control plane network element; another is that the control plane network element also notifies the management plane network element at the same time, for example, by reporting alarm information to the management plane network element, the management plane network element is notified that the femtocell is abnormally disconnected from the network.

Management surface

After detecting that the home base station abnormally exits the network, the management plane network element performs at least one of the following processing: informing other network elements of the management plane so that the other network elements of the management plane can process abnormal network quitting of the femtocell; sending alarm information; and updating the stored state of the home base station. Because the network elements of each management plane do not completely perform the same network quitting processing on the femtocell, the following steps are firstly performed:

the network quitting process of the home base station by the son server may include at least one of the following: the SONServer updates a neighbor cell list of a neighbor cell base station of the femtocell (namely, the neighbor cell list contains the femtocell base station); deleting the information of the home base station; updating the state information of the home base station; and sending alarm information.

The MgmtSystem performing network quitting processing of the home base station may include at least one of the following: updating a neighbor cell list of a neighbor cell base station of the femtocell (namely, the neighbor cell list contains the femtocell base station); the MgmtSystem stops actively updating the configuration information (such as CSG member information) of the femtocell, for example, does not send the configuration information of the femtocell and the update of the configuration information to the femtocell; the MgmtSystems delete the home base station information; the MgmtSystems update the state information of the home base station; and sending alarm information.

Wherein, the updating the neighbor list at least comprises one of the following: and deleting the home base station from the neighbor cell list, or updating the state of the home base station from the neighbor cell list.

For the case of detecting the management plane network element, on one hand, the control plane network element does not need to be notified, because the control plane and the management plane network element may have an independent detection mechanism, the control plane network element does not need to be notified by the management plane network element; another is that the management plane network element also notifies the control plane network element at the same time.

The following describes processing after the control plane network element and the management plane network element detect that the femtocell is abnormally quitted through different scenes.

In a first scenario, a femtocell triggered by a FeGW exits from a network abnormally.

For the abnormal network quitting of the femtocell triggered by the FeGW (for example, the abnormal network quitting of the femtocell is detected through a handshake mechanism between the FeGW and the femtocell), the FeGW notifies the SeGW to perform the network quitting processing of the femtocell, and the SeGW notifies the Femto-AAA to perform the network quitting processing.

Fig. 3 is a flowchart of triggering, by the FeGW, the hnb to quit the network abnormally according to the embodiment of the present invention, where as shown in fig. 3, the flowchart includes the following steps:

the step of informing the SeGW to perform the network quitting processing of the base station by the FeGW comprises the following two steps:

step S301, the FeGW detects that the hnb is abnormally away from the network, and sends a request message carrying network departure information of the hnb to the SeGW (for example, using a message WFAPNetExitRequest), where the sent message carries at least one of the following: home base station identifier of the quit network (e.g. IP address, MAC address of the home base station, or IEEE defined identifier, etc.), type of the quit network of the home base station, and reason for the quit network of the home base station.

Preferably, in this step, after the FeGW detects that the femtocell is abnormally quitted, the FeGW performs the foregoing network quitting processing on the femtocell.

In step S302, after receiving the network resignation information of the hnb sent by the FeGW, the SeGW sends a response message to the FeGW (for example, using a message wfapnetexitsesponse).

In this step, the SeGW also needs to delete the secure tunnel (e.g., IPSec tunnel) between it and the home base station. The SeGW also needs to inform Femto-AAA to process abnormal network quitting of the femtocell. The process comprises the following two steps:

step S303, after receiving the network quitting information of the hnb sent by the FeGW, the SeGW sends a message carrying the network quitting information of the hnb to Femto-AAA (for example, using message accountrequest (stop)). Wherein, the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

In step S304, after Femto-AAA receives network quitting information of Femto sent by SeGW, Femto-AAA responds response message of Femto quitting network to SeGW (for example, using message account response (stop)).

In the above steps, step S303 occurs after step S301, and step S303 and step S302 are not chronologically divided.

Preferably, after the FeGW detects that the femtocell abnormally exits the network, the FeGW performs the network exiting processing of the femtocell. The network exit processing of the home base station by the FeGW occurs after the FeGW detects that the home base station is abnormally exiting the network, and the processing does not have a chronological order with step S301, step S302, and step S303, and may occur before step 301, before step 302, or after step 302, for example.

Preferably, after receiving the message sent by the FeGW, the SeGW further performs the network resignation processing of the home base station.

Preferably, after receiving the message sent by the SeGW, Femto-AAA also performs the network quitting process of the home base station.

And in a second scenario, the femtocell triggered by the SeGW quits the network abnormally.

For the abnormal network quitting of the home base station triggered by the SeGW (for example, the abnormal network quitting of the home base station triggered by the expiration of a security tunnel between the SeGW and the home base station), the SeGW respectively notifies the FeGW and the Femto-AAA so that the SeGW and the Femto-AAA can perform the network quitting processing of the home base station. Fig. 4 is a flowchart of the SeGW triggering the hnb to quit from the network abnormally according to the embodiment of the present invention, where as shown in the figure, the flowchart includes the following steps:

and the SeGW notifies the FeGW to process abnormal network quitting of the home base station. The process comprises the following two steps:

step S401, the SeGW sends a request message carrying the femto network resize information to the FeGW (for example, using a message WFAPNetExitRequest), where the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

In step S402, after receiving the information sent by the SeGW, the FeGW sends a response message to the SeGW (for example, using a message wfapnetexitsesponse).

And the SeGW informs Femto-AAA to process abnormal network quitting of the home base station. The process comprises the following two steps:

step S403, the SeGW sends a message (for example, using a message accountrequest (stop)) carrying network resize information of the hnb to the Femto-AAA, where the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

In step S404, after Femto-AAA receives information about network resignation of home base station sent by SeGW, Femto-AAA responds response message of home network resignation to SeGW (for example, using message account response (stop)).

In the above step, the SeGW informs the FeGW and Femto-AAA that there is no priority score; that is, step S401 and step S403 have no chronological part (including parallel occurrence), and step S402 and step S404 are respectively used as the response of step S401 and step S403.

And when the SeGW detects that the home base station abnormally exits the network, the SeGW also performs the network exiting processing of the home base station.

After receiving the message sent by the SeGW, the FeGW performs the network quitting processing of the femtocell.

And when receiving the message sent by the SeGW, the Femto-AAA also performs the network quitting processing of the home base station.

Scene three, Femto-AAA triggers abnormal network quitting of home base station

For the abnormal network quit of the femtocell triggered by the Femto-AAA (for example, the Femto-AAA finds that the WFAP subscription information is expired), the SeGW and the FeGW are informed so that the SeGW can process the abnormal network quit of the femtocell. Fig. 5 is a flow chart of Femto-AAA triggered home base station abnormal network exit according to an embodiment of the present invention, as shown in fig. 5, the flow includes the following steps:

Femto-AAA informs SeGW home base station to quit network, comprising the following two steps:

step S501, Femto-AAA sends a broken link message (i.e. DiscconnectRequest message when Radius protocol is adopted, or Abort-Session-Request (ASR) Command when Diameter protocol is adopted), wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

Step S502, the SeGW sends the response message of the link-breaking request (DiscconnectACK or DisconnectictNACK message when the Radius protocol is adopted; Abort-Session-Answer (ASR) Command when the Diameter protocol is adopted) to the Femto-AAA.

After the SeGW receives the link breaking message sent by Femto-AAA, the subsequent process is consistent with the femtocell abnormal network logout procedure triggered by SeGW, that is, step S503 to step S506 are the same as step S401 to step S404 in scenario two, which is not described herein again, where in the above step, step S503 occurs after step S501, and step S503 and step S502 have no chronological order.

In the above description, the SeGW sends home base station logout information to the Femto-AAA, and when the RADIUS protocol is adopted between the SeGW and the Femto-AAA, an Accounting-Request/Stop message (Accounting-Request/Stop) for requesting to Stop Accounting is used; when the Diameter protocol is used between the SeGW and the Femto-AAA, an Accounting-Request (ACR) for requesting Accounting stop and/or a Session-Termination-Request (STR) for requesting Session Termination are defined. Of course other messages may be used to indicate that the home base station is off network.

In the above description, Femto-AAA sends Femto-logout response message, Accounting-response (stop) when Radius protocol is used, and Session-Termination-response (str) Command and/or Accounting-response (acr) Command when Diameter protocol is used, to SeGW. Of course, other messages may be used to indicate the femtocell logoff response.

The three scenes are all the interaction and network quitting processing flows among the control surface network elements after the control surface network elements detect that the home base station abnormally quits the network. Further, the control plane network element needs to notify the management plane network element of the femtocell network withdrawal to facilitate the management plane network element to perform corresponding network withdrawal processing, where the Femto-AAA or FeGW can send femtocell network withdrawal information to the management plane network element.

For the femto network (including normal network and abnormal network) quitting triggered by the FeGW, the FeGW needs to notify the network element of the management plane in addition to notifying the network element of the control plane (as described in the first scenario); the process of informing the management plane network element is as follows: the FeGW sends out the home base station network quitting information to at least one of the SONServer and the MgmtSysteme, for example, the home base station network quitting information is notified in a mode of sending an alarm. If the femtocell which is not directly triggered by the FeGW quits the network, the FeGW receives the information after the femtocell quits the network sent by the other control plane and triggers. The FeGW notifies the management plane network element to quit the network of the femtocell, and the quit processing can be performed in one of the following modes:

the first method is as follows: the method comprises the steps that a FeGW sends network quitting information of a home base station to one of an SONServer and an MgmtSystem, and one of the SONServer and the MgmtSystem, which receives the network quitting information of the home base station sent by the FeGW, sends the network quitting information of the home base station to the other.

The second method comprises the following steps: and the FeGW sends network quitting information of the home base station to the SONServer and the MgmtSystemE.

Fig. 6 is a flowchart of an operation of triggering the hnb to quit the network according to an embodiment of the present invention, and an example of notifying a management plane network element in the operation of triggering the hnb to quit the network is described below with reference to fig. 6. The FeGW trigger is generated after detecting that the femtocell leaves the network, or receiving network leaving information (including a normal or abnormal network leaving situation) of the femtocell from other network elements (e.g., SeGW).

As shown in fig. 6, the step of the FeGW notifying the son server home base station of network logout includes the following two steps:

step S601, the FeGW sends a message to inform the SONServer home base station to quit the network, wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station. For example, the FeGW may notify the SONServer using an Inform message defined by the TR-069 protocol.

Step S602, the SONServer sends back a response message to the FeGW. For example, the SONServer may respond to the FeGW with an InformResponse message defined by the TR-069 protocol.

The SONServer informs the MgmtSystemA home base station of the network quitting condition, and the method comprises the following two steps:

step S603, the son server sends a message to notify the MgmtSystem femtocell to quit the network, wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station. For example, the SONServer may notify the MgmtSystem using an Inform message defined by the TR-069 protocol, or may notify the MgmtSystem using a message defined by an Operation Administration and Maintenance (OAM) system.

In step S604, the MgmtSystem sends back a response message. The MgmtSystems can respond to the SONServer by using InformResponse messages defined by a TR-069 protocol, and can also respond to the SONServer by using messages defined by an OAM system.

In the above steps, step S603 has no chronological relationship with step S602 after step S601.

The flow diagrams of the notification of the control plane network element described in fig. 3 and 4 can be used in combination with the flow diagram of the notification of the management plane network element 6 according to the above described method.

For Femto-AAA triggered home base station network exit procedures (including normal network exit and abnormal network exit), except notifying the network element of the control plane (described in the third scenario), the network element of the management plane also needs to be notified. The process of informing the network element of the management plane is as follows: the Femto-AAA sends the home base station network quit information to at least one of the SONServer and the MgmtSysteme, for example, informs the management plane network element in a way of sending an alarm. If not, the Femto-AAA triggers the femtocell to quit the network directly, and triggers after receiving the femtocell quit network information sent by other control planes. The Femto-AAA notification management plane network element performs network quitting processing on the home base station by one of the following modes:

the first method is as follows: the Femto-AAA sends the home base station network quitting information to one of the SONServer and the MgmtSystemA, and one network element of the SONServer and the MgmtSystemA which receives the network quitting information sent by the Femto-AAA sends the home base station network quitting information to the other network element.

The second method comprises the following steps: and the Femto-AAA sends out the home base station network quit information to the SONServer and the MgmtSysteme.

Fig. 7 is a flow chart of Femto-AAA triggering home base station network logout according to an embodiment of the present invention, and an example of notifying the management plane when Femto-AAA triggers home base station network logout is described below with reference to fig. 7, where Femto-AAA triggering refers to a situation that Femto-AAA triggering itself detects that home base station network logout occurs, or network logout information (including a situation of normal or abnormal network logout) of home base stations from other network elements is received.

As shown in fig. 7, the Femto-AAA notifying MgmtSystem home base station network quit condition includes the following two steps:

step S701, Femto-AAA sends a message to inform the MgmtSystemA home base station to quit the network, wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station. Femto-AAA can Inform MgmtSystems using the Inform message defined by TR-069 protocol.

In step S702, the MgmtSystem sends back a response message to the MgmtSystem. The SONServer may respond to the Femto-AAA with an InformResponse message defined by the TR-069 protocol.

The method comprises the following steps that MgmtSystemt informs the SONServer of the network quit condition of the home base station, and the method comprises the following two steps;

step S703, the MgmtSystems sends a message to inform the SONServer home base station to quit the network, wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

In step S704, the SONServer sends back a response message to the MgmtSystem.

In S703 and S704 described above, the interactive manner between the SONServer and the MgmtSystem synchronizes S603 and S604.

In the above steps, step S703 follows step S701 without temporal sequential relationship with step S702.

The flow diagrams of the notification of the control plane network element described in fig. 4 and 5 can be used in combination with the flow diagram of the notification of the management plane network element 7 according to the above described method.

In the above step, after the management plane network element learns that the femtocell quits the network, other network quitting processing of the femtocell performed by the management plane network element is also performed.

For the network element of the management plane, detecting that the home base station abnormally exits the network, at least one of the following exists:

the management plane network element does not send network quitting information of the home base station to other network elements (including a control plane network element and other management plane network elements), and only processes network quitting related behaviors of the management plane network element and the home base station; the management plane network element sends out the home base station network quitting information to other management plane network elements so that the other management plane network elements can conveniently carry out home base station network quitting processing; and the management plane network element sends the network quitting information of the home base station to the control plane network element.

The management plane network element sends the femtocell network quitting information to the control plane network element in one of the following ways:

the first method is as follows: and the network element receiving the network quitting information of the home base station respectively processes according to the scene one, the scene two and the scene three.

The second method comprises the following steps: and the management plane network element sends the network quitting information of the home base station to each network element in the control plane.

Fig. 8 is a flow chart of the SONServer triggering the femtocell to quit the network according to the embodiment of the present invention, and an example of when the SONServer learns that the femtocell quits the network and notifies the FeGW is described below, where learning means that the SONServer detects that the femtocell quits the network or receives network quit information (including a normal or abnormal network quit situation) of the femtocell from other network elements.

As shown in fig. 8, the SONServer notifies the FeGW of the network quit condition, which includes the following two steps:

step S801, the son server sends a message to the FeGW to notify the hnb of network resignation, where the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station. Note that the Inform is a general notification message in fig. 8, and may be an Inform message in TR069, but is not limited thereto.

Step S802, the FeGW sends back a response message to the SONServer. Note that the InformResponse is a generic notification response message in fig. 8, and may be an InformResponse message in TR069, but is not limited thereto.

The FeGW may then perform network resignation processing of the home base station in the manner of scenario one.

Fig. 9 is a flow of triggering home base station network exit by the MgmtSystem according to the embodiment of the present invention, and an example of notifying Femto-AAA of network exit information of the home base station when the MgmtSystem notifies the Femto-AAA is described below, where the notification means that the MgmtSystem detects that the home base station exits the network or receives network exit information (including a normal or abnormal network exit condition) of the home base station from another network element.

As shown in fig. 9, the MgmtSystem notifies Femto-AAA home base station of network quit, which includes the following two steps:

step S901, the MgmtSystems sends a message to Femto-AAA to inform the femtocell to quit the network, wherein the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station. Note that the Inform is a generic notification message in fig. 9, and may be an Inform message in TR069, but is not limited thereto.

In step S902, Femto-AAA sends back a response message to the MgmtSystems. Note that the InformResponse is a generic notification response message in fig. 9, and may be the InformResponse message in TR069, but does not precede it.

Femto-AAA can then perform network quitting processing of the femtocell according to the mode of the third scene.

In the above description, all network elements communicating with the management plane transmit information using management plane protocol bearers, such as TR069, DOCSIS, SNMP, OMA-DM, etc.

In all the above methods and embodiments corresponding to all the methods, the interaction between the SeGW and the Femto-AAA may be based on a RADIUS protocol or a Diameter protocol.

If the RADIUS protocol is adopted, the SeGW sends an Accounting-Request/Stop message for requesting to Stop Accounting to the Femto-AAA to inform the network quitting processing of the WFAP (namely, the SeGW sends the network quitting information of the home base station to the Femto-AAA, which is equivalent to the above description); Femto-AAA responds to SeGW with an Accounting-Response/Stop message indicating that Accounting is stopped, to confirm the logoff process for the femtocell (i.e. equivalent to Femto-AAA sending a corresponding Response message to SeGW as described above).

If the Diameter protocol is adopted, the SeGW notifies the network logout processing of the WFAP by sending an Accounting-Request (ACR) message and/or a Session Termination Request (STR) message defined by the protocol to the Femto-AAA (namely, the SeGW sends the femtocell network logout information to the Femto-AAA as described above), wherein the ACR message is used for requesting Accounting stop, and the STR message is used for requesting Session Termination; the Femto-AAA then confirms the logoff process for the femtocell by sending an Accounting-Answer (ACA) message and/or a Session-Termination-Answer (STA) message to the SeGW (that is, the same as the above-described Femto-AAA sends a corresponding response message to the SeGW).

An Authenticator (Authenticator) of the home base station may be deployed in the SeGW, so the interaction between the Femto-AAA and the SeGW mentioned above may also be understood as the interaction between the Femto-AAA and the Authenticator of the home base station.

Preferably, in the embodiments corresponding to all the methods and all the methods, the interaction between the SeGW and the FeGW is performed through AAA messages, that is, messages in a Radius protocol or messages in a Diameter protocol are used to send home base station network withdrawal information and corresponding response messages; preferably, in the case of AAA message interworking, SeGW and FeGW message interworking interacts with the SeGW and AAA messages described above.

Preferably, in all the above methods and embodiments corresponding to all the methods, if the SeGW and the FeGW are jointly configured, the interaction step between the SeGW and the FeGW is removed.

It should be noted that, in all the above methods and embodiments corresponding to all the methods, the SeGW and Femto-AAA interaction may be performed by using a FeGW as AAAProxy, and the FeGW mentioned in the above embodiments corresponding to all the methods and all the methods is a FeGW registered by a user, that is, the FeGW registered by the user is different from the FeGW acting as an AAAProxy proxy. Preferably, the interaction between the SeGW and Femto-AAA is via the FeGW, which is AAAProxy. Taking the AccountRequest/Response message in Radius as an example, sending the AccountRequest message to FeGW (AAAProxy) by SeGW, and then sending the AccountRequest to Femto-AAA by FeGW (AAAProxy); Femto-AAA sends AccountResponse message to FeGW (AAAProxy), and then FeGW (AAAProxy) sends AccountResponse to SeGW.

Preferably, in the embodiments corresponding to all the methods and all the methods described above, the FeGW registered by the WFAP may be the same as the FeGW playing AAAProxy role between the SeGW and the Femto-AAA, and an abnormal network logout procedure of the home base station where the FeGW registered by the home base station is the same as the FeGW playing AAAProxy role is described below.

For the WFAP abnormal network quitting process triggered by the FeGW, the FeGW can interact with the SeGW and the Femto-AAA respectively to perform the WFAP abnormal network quitting processing. That is, in step S303 of the aforementioned fig. three, the Femto sends a message to Femto-AAA, and accordingly, in step S304, Femto-AAA responds a response message of home base station logout to Femto. Preferably, the SeGW notifies the SeGW and Femto-AAA that the home base station logout processing is not sequentially divided. This is explained in detail below with reference to fig. 10.

Fig. 10 is a flowchart of a FeGW triggering a home base station to abnormally quit from a network under the condition that the FeGW registered in the home base station is the same as the FeGW functioning as aaaprxy according to an embodiment of the present invention, where the flowchart includes the following steps:

step S1001, the FeGW detects that the hnb abnormally exits from the network, and sends a request message carrying network exit information of the hnb to the SeGW (for example, an accountrequest (stop) when a Radius protocol is used), where the sent message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

Step S1002, after receiving the network quit information of the hnb sent by the FeGW, the SeGW sends a response message (for example, account response (stop) when using the Radius protocol) to the FeGW.

In this step, the SeGW also needs to delete the secure tunnel (e.g., IPSec tunnel) between it and the home base station.

Step S1003, the FeGW sends a message carrying the network quitting information of the hnb (using AAA message, when it is a Radius protocol, using account request (stop)) to Femto-AAA. Wherein, the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

Step S1004, after Femto-AAA receives network quitting information of home base station sent by FeGW, Femto-AAA responds response message (AAA message, if it is Radius protocol, Account response (stop)) of home base station quitting network to FeGW.

In the above steps, step S1001 and step S1003 are not time-sequentially divided.

And performing abnormal network quitting processing on WFAP triggered by the SeGW, wherein the interaction between the SeGW and the FeGW is performed during the interaction between the SeGW and the Femto-AAA, so that a separate interaction flow between the SeGW and the FeGW is not needed. That is, in the fourth drawing, step S401 and step S402 are eliminated; in step S403, the SeGW sends the message to the fegw (aaaproxy), and then the SeGW (aaaproxy) sends the corresponding message to Femto-AAA; accordingly, in step S404, Femto-AAA transmits a message to the FeGW, which is transmitting a corresponding message to the SeGW. In this case, the FeGW receives the message transmitted from the SeGW, and then performs network resignation processing of the home base station. This is explained in detail below with reference to fig. 11.

Step S1102, the FeGW sends a message (for example, account request (stop)) carrying network resize information of the hnb to the Femto-AAA, where the message carries at least one of the following: the home base station identifier of the quit network, the type of the quit network of the home base station and the reason of the quit network of the home base station.

Step S1103, after receiving the network quitting information sent by the Femto bs, the Femto-AAA responds a response message of home network quitting (e.g., account response (stop) when using the Radius protocol) to the Femto.

In step S1104, the FeGW sends a response message (e.g., accountresponse (stop) when using the Radius protocol) to the SeGW.

And performing abnormal network quitting processing on WFAP triggered by Femto-AAA, wherein the interaction between Femto-AAA and FeGW is performed simultaneously during the interaction between Femto-AAA and SeGW, so that a separate interaction flow between SeGW and FeGW is not needed. That is, in the fifth embodiment, step S503 and step S504 are omitted; in step S505, the SeGW sends a message to the fegw (aaaproxy), and then the SeGW (aaaproxy) sends a corresponding message to Femto-AAA; correspondingly, in step S506, Femto-AAA sends a message to FeGW, which is sending a corresponding message to SeGW. In this case, the FeGW receives the message transmitted from the SeGW, and then performs network resignation processing of the home base station. This is explained in detail below with reference to fig. 12.

Fig. 12 is a flow chart of Femto-AAA triggering home base station logout under the condition that the FeGW registered in the home base station is the same as the FeGW functioning as aaaprxy according to the embodiment of the present invention, where the flow includes the following steps:

In step S1205, after receiving the network quitting information of the femtocell sent by the Femto-AAA, Femto-AAA responds a response message of home network quitting to the Femto (for example, using message account response (stop)).

In step S1206, the FeGW sends a response message (e.g., accountrequest (stop) when the Radius protocol is adopted) to the SeGW.

In all the methods and embodiments corresponding to all the methods, the home base station quit processing is performed by interaction between a network element (Femto-AAA or FeGW) of the control plane and a network element (son server or MgmtSystem) of the management plane, and various network management protocols can be adopted, such as TR069, SNMP, DOCSIS, OMA-DM, and the like. If the TR069 protocol is adopted, the control plane network element informs the management plane network element home base station network quit information to adopt the following interactive flow: the control plane network element uses the Inform message to Inform, and the management plane network element uses the Inform response message to send back a response to the control plane network element; if the TR069 protocol is adopted, the management plane network element informs the control plane network element that the home base station quits the network by adopting the following interactive flow: the management plane network element sends a connection request (CONNECTIONREQUEST) to the control plane network element; the control plane network element sends an Inform message to the management plane network element; the management plane network element sends an inform response message to the control plane network element; the management plane network element sends a set parameter value (SetParameterValues) message to the control plane network element, and using the message, the management plane network element may notify the control plane network element of network quitting information of a certain specific femtocell.

The "whether to delete the context of the home base station" indicates whether the network element deletes the context information of the home base station stored in the network element, wherein the "home base station behavior" is used for indicating that the home base station which quits the network triggers the behavior of the service terminal obtained on the home base station, such as switching to other base stations, quitting the network and the like.

In all the above scenarios and all the corresponding embodiments of the scenarios, the identification information of the home base station includes, but is not limited to, one or more of the following identifications: IP address, MAC address, IEEE assigned identification.

It should be noted that, in the above description, the network element a sends the information carrying the XXX content to the network element B, and the network element a sends the message carrying the XXX content to the network element B, which means the same.

The control plane network element and the management plane network element in the invention are not absolutely divided, when the control plane network element and the management plane network element are communicated, if a management plane protocol is adopted, the control plane network element has the function of the management plane network element at the same time (for example, when the control plane network elements such as WFAP, FeGW and the like and the MgmtSystem adopt the management plane protocol (for example, TR069) for communication, the control plane network element also resides in a client of the management plane at the same time, and has the function of the management plane at the same time); if the control plane protocol communication is adopted between the management plane network element and the management plane network element, the management plane network element also has the function of the control plane network element; if they adopt the upper application layer protocol to communicate, the control plane network element and the management plane network element both have the function of the data plane network element.

In summary, the above method of the present invention provides a complete network logout processing procedure for the hnb, so that the SON server, the MgmtSystem, the Femto-GW, the SeGW, and the Femto-AAA can maintain correct hnb information and release the relevant resources of the hnb that has logout.
