Description

Description of the invention A method and system for managing a home base station

The present invention relates to the field of communications technologies, and in particular, to a method and system for managing a home base station. Background technique

In the wireless network communication system, with the development of the Internet (Internet) and the wide application of various wireless services, users have put forward higher requirements for the bandwidth, convenience, and cost of the wireless network. On the other hand, from the perspective of operators, it is necessary to make full use of the resources of existing networks, expand capacity, reduce costs, and better serve users.

In order to fully meet the above requirements and the development needs of the network, a home base station (Home Node B) is proposed. Home Node B is a home-based micro base station. Users can arrange such base stations in hotspot coverage areas such as homes and offices, and access the mobile communication network through the Internet to obtain wireless communication services. The introduction of Home Node B solves the bottleneck problem of air interface resources in wireless data services, enabling users to enjoy high-speed, high-bandwidth network services. On the other hand, since Home Node B accesses the mobile communication network through the Internet, it saves the transmission cost of the mobile operator and increases the capacity of the mobile network. Moreover, Home Node B is mainly used in hotspots such as homes and offices, as well as blind spots in remote areas, thus improving the coverage of mobile networks and optimizing the quality of the network.

In the current mobile communication network, the online condition of the network node has a great influence on the user's service and the operator's operation strategy. The connection and disconnection of network contacts need to fully consider the impact on the user's services and the impact on the overall network performance. Therefore, it is necessary to consider the network planning and layout of the operators, plan the network in advance, and complete the network according to the planned content. Access and disconnection.

Since the user will start the Home Node B anytime and anywhere according to his own needs, so that the Home Node B accesses the mobile communication network through the Internet, the mobile communication network cannot predict and plan the access time and disconnection time of the Home Node B, so the Home Node B access to network resource management A new demand has been put forward, and the mobile communication network needs to be managed according to the online situation of Home Node B. For example, when the Home Node B accesses the mobile communication network, the mobile communication network needs to allocate corresponding resources; when the Home Node B leaves the mobile communication network, the mobile communication network needs to release resources allocated to the Home Node B (including wireless Resources and transmission resources, etc.). Therefore, the mobile communication network needs to know the online status of Home Node B in time so that it can be managed effectively.

In the current wireless network, the access and disconnection of the macro Node B (which can cover a large area and a base station that can serve the public) is determined and implemented according to the situation of the operator's network planning, that is, The online status of the macro Node B is under the control of the operator. The traditional element management system (EMS) configures and coordinates related resources through manual participation according to the operator's network planning data. That is, the EMS management of the macro Node B is completely based on the operator. Planning to do, and for macro Node B, the allocation and recycling of resources is relatively static. Therefore, the EMS is relatively static for the online management of the macro Node B. When an abnormality occurs in the macro Node B online situation, the EMS can judge the online situation through information such as heartbeat and network alarm, without automatically adjusting the resource allocation.

The inventor found in the process of implementing the present invention that the above scheme is more suitable for the macro Node B, but for the Home Node B, the above scheme is not suitable, and there are obvious disadvantages. For example, network planning data (referred to as network planning data) cannot be overwritten by Home Node B. The reason for this problem is:

1), the number of Home Node B is large, far exceeding the number of macro Node Bs, and it is difficult for manual network data to cover all Home Node B;

2), since the access time of the Home Node B is random, the network cannot predict the information, so the network planning cannot consider the situation of the Home Node B;

3), the online status of Home Node B is not controlled by the operator, and the location of Home Node B is not fixed, and it is possible to move within a certain range. Therefore, the above management policy for macro Node B cannot be applied to Home Node B.

According to the scheme as described above, since the EMS cannot obtain information such as network planning data, Home Node B's online situation, so it is difficult for EMS to effectively configure and coordinate related resources, making it difficult to effectively manage Home Node B.

There is another solution in the prior art, that is, the network considers the usage of the global resource according to the situation of the Home Node B that may be accessed, and allocates corresponding resources in advance; the EMS allocates resources according to the foregoing for the Home Node B. Manage it. This pre-allocated resource is relatively static. For a certain Home Node B, regardless of whether it is online or not, the resources allocated to it are present. That is, the management of the Home Node B by EMS is relative. still.

The above-mentioned scheme also has obvious disadvantages:

1) First, the number of Home Node Bs that may be accessed in the network is huge. If the network makes a global plan for all possible Home Node Bs in advance, the workload of this work is too large; The number of Node B is huge, and there may be cases where consideration of some aspects is not comprehensive enough, which may cause conflicts;

2) Secondly, for operators, network resources are limited. In order to provide better services to more users, reasonable resource allocation is an important issue. A huge number of Home Node Bs—will not always be online, and generally will not be online at the same time. Therefore, if you statically allocate the corresponding network resources for each Home Node B, it will cause a great waste of resources, and The management strategy is also difficult to meet the needs of all users for the service. Summary of the invention

FIG. 1 is a schematic diagram of state transition of an online situation of a Home Node B according to an embodiment of the present invention; FIG. 2 is a schematic structural diagram of a home base station management system according to an embodiment of the present invention. detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

In the embodiment of the present invention, a method for managing a home base station is provided, by which the network element management system can be based on the stored online status of the Home Node B and the signal fed back by the Home Node B (eg, a power-on signal, The home node B is managed by the power-off signal, the detection result, and the like, so that the home Node B can be effectively managed according to different online conditions of the Home Node B.

FIG. 1 is a schematic diagram showing state transition of an online situation of a Home Node B according to an embodiment of the present invention. As shown in Figure 1, the online status of Home Node B can be divided into power-on state, online state, power-off state, and offline state. The following is a brief introduction to these four states.

Offline status: The Home Node B is offline, and has no contact with the mobile network. The network side does not see the status of the Home Node B at all;

Powering on status: After the Home Node B sends a power-on signal, the network configures the status of the relevant network resources.

Online status: that is, Home Node B has been connected to the network, and has allocated relevant network resources, and is in a state of being put into use and providing services;

Power off status: That is, Home Node B sends a power-off signal, and the network recovers the status of related network resources.

The mutual conversion relationship between the above four states is shown in Figure 1:

When the Home Node B is offline, the Home Node B realizes the transition from the offline state to the power-on state by sending a power-on signal to the network.

When Home Node B is in the power-on state, Home Node B can complete the transition to the online state through the power-on process. During the power-on process, the network authenticates and authenticates the Home Node B and allocates relevant network resources to it. If the power-on process fails, Home Node B will return to the offline state and send a power-off signal. If Home Node B continuously sends multiple power-on signals due to some special conditions during power-on, Home Node B will still Continue to maintain the power-on state; When Home Node B is online, Home Node B can be switched to the power-off state by sending a power-off signal; if Home Node B is directly online from certain special conditions (for example, when Home Node B is powered down, etc.) The state transitions to the offline state, and when the power-off signal is sent in the future, the system does not receive the power-off signal of the Home Node B at this time, and does not know that the Home Node B is already offline, but the system can be followed by the Home Node. When the online status of B is detected, the situation is known, that is, when the system does not detect the online status of the Home Node B, the system knows that the online status of the Home Node B is offline; if the Home Node B is online, the Home Node B performs an instantaneous shutdown/power-on operation, and Home Node B will remain online;

When Home Node B is in the power-off state, Home Node B can complete the power-off process through the power-off process, and switch from the power-off state to the offline state, and the network recovers related network resources.

The NE management system (such as the EMS with the function of managing the home base station) can be described in the online management of the Home Node B according to the different online conditions of the Home Node B. The following describes the NE management system in detail through specific embodiments. Home Node B's power-on state, online state, and power-off state management method.

The first preferred embodiment: management of the power state of the Home Node B by the network element management system. 1. The power-on process of Home Node B.

After receiving the power-on signal of the Home Node B, the network authenticates and authenticates the Home Node B, and allocates related network resources to the Home Node B to complete the power-on process. In this process, since the Home Node B needs to interact with the NE management system, the NE management system can learn the online status of the Home Node B during the interaction process. After the Home Node B completes the power-on process (ie, the NE management) The system allocates network resources for the Home Node B. After the Home Node B can be put into use, the Home Node B enters the online state, and the network element management system updates the stored online status of the Home Node B to the online state.

2. The network element management system continuously receives the power-on signal of Home Node B.

The network element management system (or other network function entity, such as a gateway) may continuously receive the power-on signal of the Home Node B entering the power-on process, which is an exception. For this For a continuous power-on signal, the network element management system (or other network function entity, such as a gateway) can perform the combining process, for example, if the network element management system receives the same one within a preset time interval The continuous power-on signal of Home Node B (which can be judged by information such as the Home Node B identifier), then the network element management system (or other network function entity, such as a gateway) considers that these consecutive power-on signals belong to the same request, only One processing is performed, and the other power-on signals are not processed.

3. The Home Node B power-on process fails.

During the power-on of the Home Node B, there may be some reasons that the power-on fails. In the case of a power failure, the NE management system needs to perform different processing according to the failure reason.

1) The authentication and authentication process of Home Node B failed. In this case, since the network has not allocated the relevant network resources for the Home Node B, and has no influence on the network resources, the network element management system only needs to update the stored online status of the Home Node B to the offline state, and There is no need to adjust the network resources of the Home Node B.

2) The network has allocated some network resources to Home Node B, but failed to configure the rest of the resources. For example, a transmission resource has been allocated for Home Node B and failed when allocating wireless resources. In this case, there are two processing methods as described below:

A. The network element management system updates the online status of the stored Home Node B to an offline state, and then directly releases the network resources that have been allocated to the Home Node B, and no longer performs subsequent resources. Allocation processing, waiting for the next access request of the Home Node B (ie, the power-on signal);

B. The network element management system temporarily reserves the network resources that have been allocated to the Home Node B, and restarts a process of allocating the remaining resources to the Home Node B. If the remaining resources are allocated for a predetermined period of time, If the failure fails, or the process of allocating the remaining resources fails more than a preset number of times, the network element management system updates the stored online status of the Home Node B to an offline state, and releases all the items that have been allocated to the Home Node B. The network resource waits for the next access request of the Home Node B (ie, the power-on signal).

4. During the power-on of the Home Node B, the network element management system receives the Home Node again. B's power-off signal.

During the power-on of the Home Node B, the NE management system may receive the power-off signal sent by the Home Node B. For example, the user turns off the power. In this case, since the secure connection may not be established between the Home Node B and the network element management system, the power-off signal may not be directly sent by the Home Node B, or may be by other network entities. (for example, the access gateway) sent. After receiving the power-off signal, the network element management system needs to perform corresponding processing according to the process of the power-on process:

1) When the Home Node B is powered on, it receives the power-off signal when performing related authentication and authentication. Since the network element management system has not allocated the corresponding network resources for the Home Node B, there is nothing for the network resources. In this case, the network element management system only needs to update the online status of the Home Node B to an offline state, and does not need to adjust the network resource of the Home Node B.

2) When the Home Node B is in the power-on state and has completed the relevant authentication and authentication process, when the network element management system has assigned the relevant network resources, if the network element management system receives the power-off of the Home Node B The signal, the network element management system needs to update the stored online status of the Home Node B to an offline state, and release all network resources that have been allocated to the Home Node B.

3), when the Home Node B is in the power-on state and then power-off operation, and the network element management system does not receive the power-off signal of the Home Node B, if the Home Node B is being authenticated with the network element management system Authentication, the network element management system has not allocated the corresponding network resources for the Home Node B. At this time, the network element management system does not know that the Home Node B is powered off, so the network element management system continues to power on with the Home Node B. Process-related operations, in which the network element management system needs to exchange information with the Home Node B; therefore, when the network element management system does not receive feedback from the Home Node B within a preset time In the case of information, the network element management system knows that the Home Node B has been powered off, so the network element management system can terminate the power-on process of the Home Node B, and update the stored online status of the Home Node B to offline. Status; if the authentication and authentication process of Home Node B has been completed, the NE management system is configuring related resources for Home Node B. At this time, the NE management system I don't know that the Home Node B is powered off. Therefore, the NE management system will continue to process the Home Node B power-on process, continue to configure the Home Node B, and send configuration parameters to the Home Node B. The configuration parameter feedback sent by the Home Node B is required. If the network element management system does not receive the feedback information of the home Node B within a certain period of time, the network element management system can consider that the home node B is already offline, so the subsequent power-on process is not performed, and the stored home is The online status of Node B is updated to the offline state, and all network resources that have been allocated to the Home Node B are released. Second Preferred Embodiment: The management of the home state of the Home Node B by the network element management system. When the online status of the Home NodeB is online, the network element management system needs to promptly detect the change of the online status of the Home NodeB, so as to timely update the online status of the stored Home NodeB, and timely adjust the network resources. This enables efficient management of Home NodeB. Therefore, when the Home NodeB is online, the management of the Home NodeB by the network element management system mainly detects the online status of the Home NodeB, adjusts the network resources, updates the stored online status of the Home NodeB, and changes the status of the Home NodeB. Manage.

1. The NE management system detects the online status of the Home Node B by using the following three methods:

1. The network element management system detects the online status of the Home Node B through the underlying bearer (for example, the transport layer) between the Home Node B and the element management system.

The underlying bearer is the basis for the Home Node B to connect to the mobile network. If the NE management system can know the connection status of the underlying bearer, the NE management system can know the online status of the Home Node B. Therefore, the online status of the Home Node B can be known from the status information carried by the underlying by the two schemes as follows:

1) When the state of the underlying bearer changes, the underlying bearer sends the corresponding state change information to the network element management system, and after receiving the state change information of the underlying bearer, the network element management system can infer the online of the Home Node B. Happening. For example, if the connection of the underlying bearer is interrupted, the Home Node B is definitely offline, so the network element management system can update the stored accordingly. Home Node B online situation.

A. The link detection mechanism of the underlying bearer itself is used to detect the state of the underlying bearer. For the bottom layer

For protocols such as TCP, SCTP or HTTP, the underlying bearer can detect the link status through the handshake mechanism. Therefore, the link detection function of the Home Node B to the NE management system can be completed by using the detection mechanism of TCP, SCTP or HTTP protocol itself.

B. The security access gateway (SecGW) is used to detect the state of the underlying bearer. Since the connection between the Home Node B and other nodes in the mobile network is performed by the SecGW, the connection status of the Home Node B to the SecGW can also be used as a basis for determining the link state of the Home Node B to the network element management system, so The detection of the connection status is completed on the SecGW. Once there is any change in the connection state, the SecGW can detect the change. For example, if the state of the S1 link, the X2 link, or the Itf-S link changes, these changes can be detected on the SecGW.

C. When the connection between the Home Node B and the network element management system uses the Network Time Protocol (NTP), the timing information of the NTP can also be used to determine the link status of the transport layer, thereby obtaining the link status. Change information.

2) The network element management system actively queries the status information of the underlying bearer. This method can be divided into two cases as follows:

A. The network element management system periodically queries the status information of the underlying bearer, and determines the online status of the Home Node B according to the status information of the underlying bearer. Specifically, after the home Node B is online, the network element management system starts a periodic state query operation, periodically sends a status query message to the underlying bearer, detects the underlying transport layer state, and obtains a Home Node according to the detected result. B's online situation. The operation may be that the network element management system periodically detects the status of the underlying bearer link of all the Home Node Bs; or may poll all the Home Node Bs, and perform the underlying bearer chain for the Home Node B in a time-sharing manner. Road state detection, thereby reducing the burden on the network element management system. The detection of the underlying bearer state here may also be the monitoring result of the network element management system querying the SecGW for the underlying bearer state.

B. The network element management system is based on a signaling link between the network element management system and Home Node B. The data traffic situation, to start the corresponding status query operation.

The element management system monitors the information traffic on the operation maintenance link between the Home Node B and the element management system in real time. The detection of the operation and maintenance link information traffic may be based on the detection of the transport layer data traffic, for example, the traffic of the data packet may be detected at layer 2; or may be classified and detected at the application layer according to different message types. For example, on the operation and maintenance link between the network element management system and the home Node B, the message types such as notifications, commands, or file transfers are respectively detected. The detection of the traffic of the operation and maintenance link information may be determined in a direction, for example, detecting the data traffic of the Home Node B to the network element management system. If the data flow of the Home Node B to the network element management system is not zero, It is indicated that the Home Node B has a message sent to the network element management system, so the operation and maintenance link of the Home Node B to the network element management system is good; if there is a handshake mechanism for the data packet of the network element management system to the Home Node B, Only when the NE management system receives the response from Home Node B, it indicates that the operation and maintenance link of Home Node B to the NE management system is good. When performing data traffic detection, it can be determined that the above data traffic of "operation and maintenance link is good" can be called effective data traffic, that is, data traffic sent by Home Node B to the network element management system or the network element management system. Data traffic sent to Home Node B and received a response from Home Node B.

The network element management system herein may also include other management devices for managing the home base station, such as a home base station dedicated management device, or other network entities that manage the home base station, such as a core network entity.

The operation and maintenance link herein may also include a management link between other home base station management devices and the home base station, or other signaling link between the network entity managing the home base station and the home base station.

In a certain period of time, when the effective data traffic on the operation and maintenance link between the network element management system and the home Node B is non-zero, it indicates that there is information transmission between the Home Node B and the network element management system, so Home Node B should The online element management system does not need to perform further Home Node B online condition detection; when the effective data traffic on the operation and maintenance link between the network element management system and Home Node B is zero, the network element management The system needs further inquiry The state information carried by the bottom layer is used as a basis for judging whether the Home Node B is in an online state: the network element management system sends a status query message to the underlying bearer, and the underlying bearer returns the status information of the underlying link after receiving the query message. The network element management system determines whether the Home Node B is online according to the status information of the returned underlying link.

2. The NE management system detects the online status of the Home Node B through an operation and maintenance link with the Home Node B.

The NE management system can also use the operation link maintenance layer information between the Home Node B and the NE management system to determine the online status of the Home Node B.

1) The network element management system sends a status query command to the Home Node B.

After the link between the home node B and the network element management system is established, after the network element management system completes the configuration of the home node B, that is, after the power-on process of the home node B is completed, the network element management system can start the pair according to the situation. Home Node B online detection process.

A. Periodically detected. That is, the network element management system periodically sends an online situation query command to the Home Node B. After receiving the status query command, the Home Node B returns a status indication information to the network element management system. If the network element management system does not receive the information returned by the Home Node B within a predetermined period of time, the network element management system considers that the operation and maintenance link to the Home Node B is interrupted, and accordingly performs corresponding processing. In the above operation, the network element management system may periodically send a status query command to all Home Node Bs to detect the online status of the Home Node; or may poll all Home Node Bs in a time-sharing manner. The status query command is sent to the Home Node B to detect its status, thereby reducing the burden on the network element management system.

B. The network element management system sends a corresponding status query command to the Home Node B according to the data traffic condition of the operation maintenance link between the network element management system and the home Node B. First, the network element management system monitors the data traffic on the operation and maintenance link between the Home Node B and the network element management system in real time, where the network element management system detects the operation and maintenance link information traffic and the above network element The management system detects the home Node B online through the underlying bearer (transport layer) The detection mechanism of the situation is the same. During a certain period of time, when the effective data traffic on the operation and maintenance link between the network element management system and the home Node B is non-zero, the information is transmitted between the Home Node B and the network element management system, and the Home Node B is online. Status, at this time, the network element management system does not need further processing; when the effective data traffic on the operation and maintenance link between the network element management system and the home Node B is zero, the network element management system sends a status to the Home Node B. After receiving the status query command, the Home Node B returns an online status indication to the network element management system. After receiving the online status indication, the network element management system indicates that the Home Node B is online; The management system does not receive the status indication response from the Home Node B within a certain period of time after the status query command is issued. The network element management system considers that the operation and maintenance link between the network element management system and the Home Node B is interrupted. Thereby performing related processing.

2) Home Node B periodically sends online notifications to the NE management system.

After the power-on is completed, the Home Node B periodically sends an online status notification to the network element management system through the operation and maintenance link between the network element management system and the Home Node B to indicate the online status of the Home Node B. After receiving the online status notification of the Home Node B, the network element management system can know that the Home Node B is online; if the network element management system does not receive the online status sent by the Home Node B within a preset period of time The notification indicates that the operation and maintenance link status between the network element management system and the Home Node B is interrupted, and the network element management system determines that the online status of the home base station is offline, and performs corresponding processing.

When the network element management system detects that the operation and maintenance link between the network element management system and the home Node B is interrupted, the network element management system has two processing modes as follows:

A. Because the operation and maintenance link between the network element management system and the home Node B is interrupted, the Home Node B will be in an uncontrollable state for the operator, and the network element management system is directly released and assigned to the Home Node. The related network resources of B, correspondingly update the stored online status of the Home Node B to an offline state.

B. When the operation and maintenance link between the network element management system and Home Node B is interrupted, the link from Home Node B to other network nodes may not be interrupted at this time, and the user may Still using the services of the network. Therefore, the network element management system of the Home Node B can find the mobility management entity (MME) connected to the Home Node B according to the identity information of the Home Node B, and through the network element management system with the found MME. The interaction obtains the status of the SI link between the Home Node B and the MME. If the SI link is interrupted, the Home Node B has disconnected from the network. Therefore, the NE management system updates the stored online status of the Home Node B to an offline state, and releases the assigned to the Home. The network resource of the Node B; if the S1 link is not interrupted, it means that the connection from the Home Node B to the NE management system is out of order. Considering the impact on the user and the network, the NE management system is in contact with the Home. A related network entity connected by the Node B (for example, an MME connected to the Home Node B through the SI link or another Node B connected to the Home Node B through the X2 link) sends a disconnect message, and then the network element The management system releases the relevant network resources that have been allocated to the Home Node B, and updates the stored online status of the Home Node B to an offline state.

3. The network element management system obtains the online status of the Home Node B through the S1 link information between the Home Node B and the MME.

The network element management system can also obtain its online status through the interaction information between the Home Node B and the MME. For the network element management system to which the Home Node B belongs, the interaction information between the Home Node B and the MME cannot be obtained directly. Therefore, the interaction information of the MME is obtained through the network element management system of the MME.

1) The home element management system of the Home Node B sends a query request to the network element management system of the MME.

The method can also be divided into periodic detection and condition detection.

A. The network element management system of the Home Node B periodically sends a query message to the network element management system of the MME according to the information of the MME connected to the Home Node B, and obtains the online status of the Home Node B, the query. The message carries the identification information of the corresponding Home Node B. After receiving the query message of the network element management system of the home Node B, the MME's network element management system queries the S1 link between the Home Node B and the MME according to the identifier of the Home Node B carried in the query message. Status information, according to the status information of the S 1 link to Home Node B The network element management system returns the online status information of Home Node B. As in the previous embodiment, the detecting operation may be that the network element management system periodically sends a status query command to the network element management system of the MME to which all Home Node Bs are connected, and detects the online status of the Home Node B. The home node B may be polled, and the status query command may be sent to the network element management system of the MME connected to the Home Node B in a time-sharing manner to detect the online status of the Home Node B, thereby reducing the network element management. The burden of the system.

B. The network element management system sends a corresponding status query message to the network element management system of the MME connected to the corresponding Home Node B according to the data traffic condition of the operation and maintenance link between the network element management system and the Home Node B.

The network element management system monitors the data traffic on the operation maintenance link between the Home Node B and the network element management system in real time. This method of detecting data traffic is the same as the foregoing method of detecting data traffic. That is, when the effective data traffic of the operation and maintenance link between the network element management system and the home Node B is non-zero within a certain period of time, the Home Node B is in an online state, and the network element management system does not need to pass. Other ways to detect the online status of the Home Node B; if the valid data traffic of the operation and maintenance link between the network element management system and the Home Node B is zero within a certain period of time, then the network element of the Home Node B The management system sends an inquiry message to the network element management system of the MME connected to the Home Node B according to the information of the MME connected to the Home Node B, and obtains the online status of the Home Node B. The information about the MME to which the Home Node B is connected may be obtained by the network element management system of the Home Node B according to the identity information of the MME, and querying the corresponding correspondence server (for example, a domain name server or a dynamic host configuration protocol server). .

2) The network element management system of the MME sends a Home Node B state change message to the network element management system of the Home Node B.

After the power-on process of the Home Node B is completed, the corresponding S1 link is established. When the online status of the Home Node B changes, the status of the corresponding S1 link changes. After the network element management system of the MME detects that the state of the SI link corresponding to the Home Node B changes, the corresponding state change message is sent to the network element management system of the Home Node B, where The message carries the identification information of the Home Node B. After receiving the message, the network element management system of the Home Node B performs corresponding processing to update the stored online status of the Home Node B to an offline state.

The above method requires the network element management system of the MME to know the network element management system corresponding to the Home Node B, and also needs the network element management system of the Home Node B to know the network element management system of the MME to which the Home Node B is connected, and then The horizontal interface between the network element management systems is used to deliver the corresponding information. The corresponding information between the Home Node B and the network element management system to which it belongs may be carried by the Home Node B to the service network when accessing the service network, or may be performed by the MME's network element management system according to the Home Node B. The identifier is obtained by querying the corresponding correspondence server (for example, a domain name server or a dynamic host configuration protocol server, etc.).

Through the foregoing state detection mechanism, the network element management system can timely understand the online status of the Home Node B. If the network element management system detects that the state of the Home Node B has changed, or the network element management system does not detect the Home Node B. When it is online, the network element management system will release the network resources allocated to the Home Node B, and update the stored online status of the Home Node B to an offline state.

During the Home Node B online condition detection process, one type of detection method as described above may be taken according to actual needs, or a combination of the above various detection methods may be taken.

2. When the Home Node B is online, the user performs an instantaneous shutdown/power-on operation on the Home Node B, and the network element management system performs corresponding detection processing on the Home Node B.

When the Home Node B is online, the user may perform an instant turn-off/power-on operation on the Home Node B, that is, the user immediately starts the power-on operation after the power-off, and the time interval between the power-off and the power-on is 4 inches. The NE management system may receive the power-on signal of the Home Node B before detecting that the Home Node B is shut down. For example, in the case of a user performing an instantaneous power off/on operation, the Home Node B does not have time to send a power down signal; or because of a problem with the transmission network (eg, the route is different), although the Home Node B normally sends a power down signal. However, the next power-on signal arrives at the network element management system first than the above-mentioned power-off signal.

At this point, Home Node B is still online, and the NE management system is receiving the The power-on signal of Home Node B can be processed as follows according to different situations:

1) When the network element management system receives the power-on signal of the Home Node B, if the network element management system has not detected the offline status of the Home Node B, or the network element management system does not receive the power-off of the Home Node B The network element management system does not need to process the power-on signal, that is, it does not need to update the stored online status of the Home Node B, and does not need to adjust the network resource of the Home Node B.

2) After receiving the power-on signal of Home Node B, the network element management system receives the power-off signal of the Home Node B if it receives the power-off signal of the Home Node B within a short time interval (the time interval can be preset) The network element management system determines that a momentary off/on condition has occurred on the Home Node B. At this point, the element management system can have two processing methods as described below:

Method A: The network element management system does not perform special processing on the above-mentioned instantaneous off/on condition, maintains the original network resource allocated to the Home Node B, and maintains the original online state of the Home Node B. That is, the network element management system does not process the power-off signal in the case of the above instantaneous off/on.

In the case of an abnormal situation, that is, when the Home Node B is actually powered off (ie, is offline), the network element management system can learn that the Home Node B is offline according to the detection result of the online situation of the Home Node B, and performs The next step.

Method B: After determining that the momentary power on/off occurs on the Home Node B, the network element management system instructs the Home Node B to measure the environment around it. If the network element management system does not receive the measurement report of the Home Node B within the specified time, the network element management system considers that the Home Node B is indeed powered off, thereby performing the next processing; if within the specified time, the network After the meta management system receives the measurement report of Home Node B, the network element management system needs to perform different processing according to the measurement report as follows:

i), the network element management system correlates the relevant environmental information (for example, neighboring cell power, interference, etc.) in the measurement of the Home Node B with the related environmental information of the Home Node B saved in the previous network element management system. Compare. The comparison needs to have a principle, which can be derived from the operator's strategy (for example, the interference control strategy), or the system can be based on the actual situation. Under the premise of considering the impact on the system, certain judgment criteria are made, for example, preset thresholds for various effects on the system. If the above comparison result is within the preset threshold

(ie, less than a preset threshold), the network element management system considers that the new related environment information of the Home Node B is not much different from the related environment information of the Home Node B saved in the network element management system, and the network element management system The original network resources and related configuration parameters (including wireless parameter configuration and transmission parameter configuration) assigned to the Home Node B will be maintained, and the configuration process will not be re-executed.

Ii) According to the above comparison principle, if the environmental change or the impact on the system exceeds the preset threshold, the network element management system needs to re-allocate the network resource for the Home Node B, that is, the network element management system releases the original Some of the network resources allocated to the Home Node B are re-configured to allocate new network resources (including radio resources and transmission resources).

The third preferred embodiment, the network element management system manages the power state of the Home Node B. When the Home Node B performs the power-off operation, it needs to send a power-off signal to the network, and the network element management system can perform corresponding management according to the power-off signal. The management of the NE management system when the Home Node B is in the power-off state has two cases as follows:

1) After the Home Node B performs the power-off process, the network element management system receives the power-off signal of the Home Node B. At this time, the network element management system releases the network resource allocated to the Home Node B, and the stored The online status of Home Node B is updated to the offline state, and the power-off process of Home Node B is completed.

2) After the Home Node B is powered off, the network element management system does not receive the power-off signal from the Home Node B (for example, the user directly unplugs the power, making the Home Node B unable to send a power-off signal; or the Home Node B sends out The power-off signal is turned off, but for other reasons, the network element management system does not receive the power-off signal). At this point, the element management system still considers Home Node B to be online. In this case, the management of the Home Node B by the element management system is still managed by the Home Node B online state. The network element management system detects the Home Node B online situation in time after the Home Node B is powered off by the foregoing state detection mechanism. The change, release the network resource allocated to the Home Node B, and update the stored online status of the Home Node B to an offline state.
