Description

Method and device for transmitting network management data

The present invention relates to the field of communications, and in particular to a method and apparatus for transmitting network management data in a heterogeneous network. Background technique

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art are not making All other embodiments obtained under the premise of productive labor are within the scope of the invention. The technical solution of the present invention can be applied to various communication systems, such as: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access ( WCDMA, Wideband Code Division Multiple Access Wireless), General Packet Radio Service (GPRS), Long Term Evolution (LTE), etc.

A user equipment (UE, User Equipment) may also be referred to as a mobile terminal (Mobile Terminal), a mobile station (Mobile Station), etc., and may communicate with at least one core network via a Radio Access Network (RAN). The UE exchanges voice and/or data with the radio access network.

The network element managed by the network management system in the embodiment of the present invention may be a base station (BTS, Base Transceiver Station) in GSM or CDMA, or a base station (Node B, Home Node B) in WCDMA, or may be LTE. Evolved base station (eNB or e-NodeB, evolutional Node B, Home eNB). In addition, a base station may support/manage at least one cell. When the UE needs to communicate with the network, it will select a cell to initiate network access. The network element managed by the network management system in the embodiment of the present invention may further include a user equipment, a radio network controller (RNC), an access point (AP), or a core network element, such as a mobility management entity. ( Mobility Management Entity , ΜΜΕ ).

A heterogeneous network usually consists of wireless network elements of different sizes and different roles. The wireless network element may be a macro base station, a (micro) base station, a pico base station or a home base station, etc., which may also be a network. Management system is managed.

The more network management data sent by each network element (for example, a base station) in a heterogeneous network, the more network management system receives the network management data, especially the network management system needs to manage the same repeated network management data; Alternatively, each network element reports network management data to the gateway management system at the same time period, which may cause the gateway management system to process a large amount of network management data at the same time period, thereby affecting network management performance of the heterogeneous network. It is also possible to waste communication resources of the entire heterogeneous network. Therefore, how to effectively reduce the transmission of network management data is a problem that heterogeneous networks must solve in network management.

A method for network management data transmission according to an embodiment of the present invention will be specifically described below with reference to FIG. 1, which may be used in a heterogeneous network, including the following.

11. The network element managed by the network management system determines that the network management data needs to be “3⁄4” to the network management system. The network element managed by the network management system mainly includes a base station, and may also include an access point (AP, Access Point) device of the access device WLAN, and the like.

The network element sends the network management data to the network management system according to the idle resource of the network element, where the idle resource refers to the network element processing the communication service of the network element itself. The unused resource other than the required resource; or, according to the priority of the network element, sending the notification of the network management data, the network element stops sending the network management data to the network management system.

It should be noted that the idle resource refers to an unused resource other than the resource required by the network element to process the communication service managed by the network element managed by the network management system, such as CPU resources and memory resources. Hard disk resources, physical channel resources, time slot resources, link resources, and so on.

Optionally, sending the network management data to the network management system according to the idle resource of the network element or the priority of the network element; or stopping according to the notification of canceling sending the network management data The network management data is sent to the network management system, and may be configured by the network management system to the managed network element, or may be preset in the network element managed by the network management system.

As an example, if a network problem occurs in a heterogeneous network or network maintenance is required, at least one network element may generate multiple network management data. These network management systems may be the same, may not be the same, and may be different. The network management system may receive duplicate network management data, thereby increasing the network management system to perform unnecessary processing on these repeated network management data, or the network management system may need to receive a large amount of network management data received in the same time period. Processing causes the network management system to perform unnecessary processing (for example, prioritizing non-emergency or non-critical services, or processing network management data reported by network elements that do not have idle resources, but cannot In the process, the processing fails due to further interaction with the network element that does not have idle resources, or the network element processes the same network management data, etc.).

In the embodiment of the present invention, the network element sends the network management data to the network management system according to the idle resource of the network element, the priority of the network element, or the setting of the notification of canceling the transmission of the network management data, thereby reducing the network management data, thereby reducing The network element reports the network management data to the network management system, improves the processing capability of the network management system in the heterogeneous network to the network management data, and reduces the waste of communication processing resources of the heterogeneous network.

Optionally, the network element managed by the network management system may further obtain a first threshold range from the network management system, where the first threshold range is used to instruct the network element to send the network management number to the network management system. According to the resources required at the time. When the idle resource of the network element meets the first threshold range, the network element may report the network management data to the network management system. Otherwise, even if the network element has an idle resource, the idle resource does not satisfy the first threshold range, and the network element cannot report the network management data to the network management system, thereby further reducing unnecessary transmission of the network element to the network management system. Network management data.

Further, the network management system can also set different first threshold ranges for different network management data (e.g., alarm data, performance measurement data, etc.). For example, for the alarm data, the first threshold range has a first range of values; for performance measurement data, the first threshold range has a second range of values; Then, when the network element is to send alarm data to the network management system, it can refer to the first value range to determine whether to report the report. When the network element reports the performance measurement data to the network management system, the second value range can be referred to. Whether to report the judgment; and so on.

Optionally, in a case where multiple network elements in the heterogeneous network generate network management data, only the network element whose priority meets certain conditions can send the network management data. For example, when the priority of one network element satisfies the second threshold range, the network element sends network management data; and when the priority of another network element does not satisfy the second threshold range, the network element cannot send Network management data. The second threshold range is used to indicate a priority required when the network element sends network management data to the network management system.

It should be noted that the second threshold range is usually configured by the network management system, that is, before the network management data is sent to the network management system, the network element managed by the network management system needs to acquire the second threshold range from the network management system. . The priority of the NE can be configured by the network management system, and the NE can dynamically adjust its own priority. For example, the network element can dynamically compare the network problem or the network maintenance whether it is urgent or important with the preset priority criterion, if the priority criterion is met (the priority criterion can be determined by the urgency or importance of the service) The priority corresponding to the priority criterion is configured when the network management data needs to be reported. The priority described here usually refers to the business priority, but it can also be other types of priorities.

In addition, the network management system can also set different second threshold ranges for different network management data. For example, for the alarm data, the second threshold range has a first range of values; for the notification data, the second threshold range has a second range of values; Then, when the network element reports the alarm data to the network management system, it may refer to the second threshold range of the first value range to determine whether to report the report; when the network element will notify the network management system of the data, The second threshold range of the second value range is judged whether or not to report; For example, if the network's priorities are divided into 1, 2, 3, 4, and 5 categories. If the second threshold range of the network management data reported by the network management system according to the network operation policy is 3 to 5, the network elements with the priority of 3, 4, or 5 can report the network management data. If the priority of an NE is 1, the NE cannot report network management data. However, if the network problem indicated by the network management data or the network maintenance is important or urgent, the network element can change its own priority to 3, 4 or 5, so that the network management data can be reported.

Optionally, the network element may report the network management data at the first time. The first time is used to indicate a time window required by the network element to send the network management data to the network management system. The first time may be configured by the network management system, or may be preset in the network element. In the case where the first time is configured by the network management system, the network element needs to acquire the first time from the network management system before transmitting the network management data to the network management system. Different network management data may correspond to the first time of "3⁄4 may also be different. Further, if the network element is in the first time > 3⁄4 network management data, receiving a notification to cancel sending the network management data (for example, The network management system may send the notification to the network element that sends the same network management data;), the network element stops transmitting the network management data.

Optionally, the network management system receives a predetermined number of identical network management data, and the other network element that receives the notification of canceling the transmission of the network management data stops transmitting the same network management data. When the notification of canceling the transmission of the network management data is not received, the network element transmits the network management data to the network management system at the first time.

It can be seen that, in the embodiment of the present invention, the network management data is sent to the network management system by the network element managed by the network management system, thereby improving the network management system in the heterogeneous network. The processing power of network management data reduces the waste of communication processing resources of the entire heterogeneous network.

A method for transmitting network management data according to an embodiment of the present invention will be further described below by taking a base station as an example.

For example, in one embodiment, when network management data is generated in the base station, the base station detects whether there is an idle resource. If the base station determines that there is an idle resource, the generated network management data is transmitted to the network management system, such as an OAM system, by using the idle resource.

Or, the base station obtains a first threshold range from the network management system (for example, the CPU utilization is lower than

85%), when the base station detects that the CPU utilization is lower than 85%, the network management will be generated. The data is sent to the network management system.

For example, in another embodiment, the base station acquires a second threshold range from the network management system, and when network management data is generated in the base station, it is determined whether its own priority satisfies the second threshold range. When the base station determines that its own priority satisfies the second threshold range, the generated network management data is sent to the network management system, otherwise the network management data is not transmitted.

In the embodiment of the present invention, the priority of the network element indicates the degree of importance of the service carried by the network element. Depending on the importance of the service and the type of service, the network elements of the reported network management data may also be different. Generally, a network element with a higher degree of importance of the carried service has a higher priority; a network element with a lower importance of the carried service has a lower priority. If the service is an emergency service, the network management system can report the network management data to the network management system to process the emergency service more quickly. If the service is a non-emergency service or an unimportant service, the service has a low priority. The network management data is reported by the network element to prevent the bearer network management system from processing the emergency services or important services in a timely manner because it handles the processing of these non-emergency services or unimportant services.

For example, in another embodiment, when the network management data is generated in the at least one first network element, the at least one first network element first determines the first time, and determines whether the canceled transmission network management data sent by the network management system is received. Notice. When the at least one first network element determines that the notification of canceling the transmission of the network management data sent by the network management system is received, the generated network management data is not sent to the network management system. When the at least one first network element determines that the notification of canceling the transmission of the network management data sent by the network management system is not received, the generated network management data may be sent to the network management system at the first time.

Here, since the first time configured in each network element may be different, the network management system may receive network management data at different times. If the network management system receives a plurality of identical network management data sent by a plurality of network elements at different first times, the network management system may provide other required resources, and the network management system may query the sending and sending network before sending the notification. The network element that manages the data, and sends the notification to the network element that may send the same network management data. The network management system may also broadcast the notification, and the network element that sends the same network management data may stop sending the network management data after receiving the notification; the network element that sends different network management data may receive the notification, or may not receive the notification. By the notification, if the network element that sent the different network management data receives the notification, the network element can continue to send the network management data and discard the notification. Therefore, before the network management data is sent to the network management system at the first time, if the at least one first network element receives the notification sent by the network management system to cancel the transmission of the network management data, the at least one first network element stops transmitting. The generated network management data, otherwise, the at least one first network element sends the network management data to be generated at the first time to the network management system.

The above describes how to transmit network data under various conditions. In fact, the various conditions can be combined with each other as described below.

For example, in one embodiment, when network management data is generated in at least one first network element, the at least one first network element first detects whether the idle resource satisfies a first threshold range and whether its priority satisfies a second threshold range. If the at least one first network element determines that the idle resource satisfies the first threshold range and the priority satisfies the second threshold range, the generated network management data is sent to the network management system by using the idle resource. Otherwise, if at least one first network element determines that the idle resource does not satisfy the first threshold range or the priority does not satisfy the second threshold range, then stopping the generated network management data from being sent to the network management system.

For example, in another embodiment, when network management data is generated in the at least one first network element, the at least one first network element first detects whether the idle resource meets the first threshold range, and determines whether to cancel the sending of the network management data. announcement of. If the at least one first network element determines that the idle resource satisfies the first threshold range and does not receive the notification of canceling the transmission of the network management data, the network management data generated at the first time is transmitted to the network management system by using the idle resource. Otherwise, if the at least one first network element determines that the idle resource does not satisfy the first threshold range or receives the notification of canceling the transmission of the network management data, stopping sending the generated network management data to the network management system.

For example, in another embodiment, when network management data is generated in the at least one first network element, the at least one first network element first determines whether the priority meets the second threshold range, and whether the cancellation of the network management data is received. Notice. When the at least one first network element determines that the priority satisfies the second threshold range and does not receive the notification of canceling the transmission of the network management data, the generated network management data is transmitted to the network management system at the first time. Otherwise, if the at least one first network element determines that the priority does not satisfy the second threshold range or receives the notification of canceling the transmission of the network management data, stopping sending the generated network management data to the network management system.

For example, in another embodiment, when network management data is generated in the at least one first network element, the at least one first network element first detects whether the idle resource meets the first threshold range, whether the priority meets the second threshold range, and It is judged whether or not a notification to cancel the transmission of the network management data is received. If the at least one first network element determines that the idle resource satisfies the first threshold range, and the priority meets the second threshold And if the notification of canceling the transmission of the network management data is not received, the idle management resource is used to send the generated network management data to the network management system at the first time. Otherwise, if the at least one first network element determines that the idle resource does not satisfy the first threshold range, or the priority does not satisfy the second threshold range, or receives the notification of canceling the transmission of the network management data, stopping sending the generated network management data to Network management system.

It can be seen that by setting conditions, it is possible to avoid excessive transmission of the same network management data in a heterogeneous network. If the conditions are combined, the same network management data can be further reduced.

It can be understood that the above embodiment is described by taking at least one first network element to generate network management data, but other network elements generate the same network management data except at least one first network element.

In summary, the embodiment of the present invention can effectively reduce the transmission of the same network management data by setting the conditions for sending the network management data for the network element managed by the network management system, so that the network management system receives the same network management. Data is reduced, which in turn improves network management performance.

Further, a heterogeneous network managed by a group is taken as an example. As shown in FIG. 2, Cloud 1 is a logical area divided according to network management requirements, in which network elements related to each other are classified into the same logical area Cloud 1. In FIG. 1, each base station corresponding to the macro cell 1 , the small cell 1 , and the small cell 2 belongs to the logical area Cloud l .

It is assumed that the transport layer of each base station corresponding to the macro cell 1, the small cell 1, and the small cell 2 in the logical area Cloud 1 uses the same optical fiber, and once the transmission link fails, the OAM receives the macro in the logical area Cloud 1. A plurality of alarm data transmitted by each base station corresponding to the cell 1, the small cell 1 and the small cell 2 reflecting the transmission link failure in the logical area Cloud 1. However, since these alarm data are redundant with each other, they all reflect the failure of the transmission link in the logical area Cloud 1. However, from the perspective of the network management system, it is not necessary to receive all of these alarm data.

Hereinafter, a method of transmitting network management data according to an embodiment of the present invention will be described in detail with reference to FIG. 2 and FIG. 3 in conjunction with specific embodiments. Among them, the heterogeneous networks shown in Figure 2 and Figure 3 all adopt the method of packet management.

2 is a schematic structural diagram of a heterogeneous network adopting a packet management method. In the first embodiment, assuming that a transmission link failure occurs in the logical area Cloud 1, the network management system receives more of the logical area Cloud 1 The plurality of network elements (for example, the macro cell 1 of the macro cell 1 , the small cell 1 and the small cell corresponding to the small cell 2) send a plurality of alarm data reflecting the transmission link failure in the logical area Cloud 1 , and the alarm data is Having the same information, that is, reflecting the logic In the case of the transmission link failure in the area Cloud 1, it is not necessary to receive all the alarm messages from the perspective of the network management system.

For each of the related network elements in the logical area Cloud 1, that is, the macro cell Macro Cell 1, the small cell small cell 1 and the small cell small cell 2, each base station according to the following conditions or a combination thereof determines whether it is necessary to transmit the corresponding Network management data (ie alarm data).

Condition 1: According to the current resource idle condition of the network element (for example, the base station). If the idle resource is detected, the idle resource may be used to send corresponding alarm data; if no idle resource is detected, the corresponding alarm data is not sent. Alternatively, if the first threshold range is obtained from the network management system side, if the idle resource is detected to satisfy the first threshold range, the idle resource may be used to send corresponding alarm data; if it is detected that the idle resource does not satisfy the first threshold range, for example (eg If the current idle resources are insufficient and the resources are busy, the corresponding alarm data is not sent.

Condition 2: According to the current priority of the NE. For example, if the current priority of the network element meets the second threshold range obtained from the network management system side, the network element may send corresponding alarm data. If the current priority of the network element does not meet the second threshold range, the network The element does not send the corresponding alarm data. Or, if the current priority of the NE is high, it indicates that the NE needs to process a more important service, and the corresponding alarm message can be sent by other NEs with lower priority in the same logical area Cloud 1.

Condition 3: Depending on whether a notification to cancel the transmission of network management data is received. In general, different network elements are configured with different first time. When the network management system receives a sufficient number of (preset or built-in default) same network management data, it can notify that it has not been sent for a while. The time can be determined by each base station. The notification may be in the form of a broadcast or a peer-to-peer notification of a network element in the logical area Cloud 1 that has not yet sent network management data.

In general, for a heterogeneous network using packet management as shown in FIG. 2, that is, in the case of a logical area Cloud, the network management system may determine that the logical area is still based on the network management data sent by the base station that has been received. Which base stations do not send the same network management data. For example, if the network management system receives a transmission link alert message, the network management system will know that all network elements using the transmission link may send the same alarm data. For another example, if the network management system receives the alarm data indicating that a certain cell is invalid, the network element where all the neighboring cells of the failed cell are located may send the alarm data or the notification data of the neighboring area failure. Thus, the network management system can determine which network elements need to be sent a notification to cancel the transmission of network management data. Even if the network management system cannot determine which network elements need to send a notification to cancel the transmission of the network management data, the network management system adopts a broadcast mode, that is, notifies the network that cancels the transmission to all network elements that have not yet transmitted the network management data. Manage data.

Thus, when the network management system receives a certain amount of the same network management data, it is available.

It is easy to understand that the network element can utilize one of the above conditions singly, or the above conditions can be combined to form a conditional combination. Therefore, the embodiment of the present invention can effectively reduce the transmission of the same network management data by using the conditions for sending the network management data for the network element managed by the network management system, so that the network management system receives the same network management data. Reduce, and thus improve the performance of network management.

FIG. 3 is a schematic structural diagram of a heterogeneous network adopting a packet management method. In the second embodiment, the cloud 1 is also a logical area that is divided according to network management requirements, and heterogeneous network cells that are strongly related to each other are used. It is planned to enter the same logical area Cloud 1, for example, the macro cell Macro Cell 1, the macro cell Macro Cell 2, the small cell small cell 1 and the small cell small cell 2 belong to the logical area Cloud 1.

If the macro cell Macro Cell 1 in the logical area Cloud 1 has a cell failure, the network management system receives multiple network elements corresponding to each neighboring cell of the macro cell Macro Cell 1 (for example, macro 'J, area Macro Cell 2. The macro cell 3, the small cell small cell 1, the small cell small cell 2, and the small cell corresponding to the small cell 3) send a plurality of alarm data or notification data reflecting the cell failure of the macro cell 1 of the macro cell 1 The same information exists between the alarm data or the notification data, that is, it reflects that the macro cell 1 has a cell failure, and from the perspective of the network management system, it is not necessary to receive all of the information.

For all relevant network elements in the logical area Cloud 1, that is, the macro cell Macro Cell 1, the macro cell Macro Cell 2, the small cell small cell 1 and the small cell small cell 2 corresponding to each base station shown in FIG. 3, and the logical area The related base stations other than Cloud 1 but belonging to the neighboring area of the macro cell Macro Cell 1 , that is, the respective base stations corresponding to the macro cell Macro Cell 3 and the small cell small cell 3 shown in FIG. 3 are performed according to the following conditions or a combination thereof Judging to determine whether it is necessary to send corresponding alarm data or notification data.

Condition 1: According to the current resource idle condition of the network element. If it is detected that there is an idle resource, the idle resource may be used to send corresponding alarm data; if no idle resource is detected, then Send the corresponding alarm data. Alternatively, if the first threshold range is obtained from the network management system side, if the idle resource is detected to satisfy the first threshold range, the idle resource may be used to send corresponding alarm data; if it is detected that the idle resource does not satisfy the first threshold range, for example (eg If the resource is busy, the corresponding alarm data will not be sent.

Condition 2: According to the current priority of the NE. For example, if the current priority of the network element meets the second threshold range obtained from the network management system side, the network element may send corresponding alarm data. If the current priority of the network element does not meet the second threshold range, the network The element does not send the corresponding alarm data.

Condition 3: Depending on whether a notification to cancel the transmission of network management data is received. In general, different network elements are configured with different first time. When the network management system receives a sufficient number of (preset or built-in default) same network management data, it can notify that it has not been sent for a while. It can be determined by each base station. The notification may be in the form of a broadcast or a peer-to-peer notification of a network element in the logical area Cloud 1 that has not yet sent network management data.

It is easy to understand that the network element can utilize one of the above conditions singly, or the above conditions can be combined to form a conditional combination. It can be seen that the embodiment of the present invention can effectively reduce the network management data by setting the conditions for sending the network management data for the network element managed by the network management system, so that the same network management data received by the network management system is reduced or the same. The time period receives a large amount of network management data reduction, thereby improving the performance of network management.

The above content is a method for transmitting network management data according to an embodiment of the present invention from the perspective of a network element. A method of transmitting network management data according to an embodiment of the present invention will now be described from the perspective of a network management system in conjunction with FIG.

41. The network management system receives network management data sent by at least one first network element.

Generally, before transmitting to the at least one second network element a notification to cancel the transmission of the network management data, the network management system further needs to query the at least one second network element that has not transmitted the network management data.

It can be understood that the at least one second network element may be each of which needs to send the same network management data as the network management data of the at least one first network element. Alternatively, the at least one second network element needs to send the same network management data as the network management data of the at least one first network element, and some parts do not necessarily need to be sent with the at least one first The network management data of the network element is the same network management data.

It can be seen that the network management data is determined according to which condition (for example, the idle resource satisfies the first threshold range, or the priority meets the second threshold range, or the notification of canceling the transmission of the network management data is not received). In the case, as long as the network management system receives the preset number of network management data, the network management system may send a notification to cancel sending the network management data to other network elements that have not sent the same network management data.

It is easy to understand that, in the case that the network element performs network management data transmission according to the notification that the network management data is not received, or the various combinations thereof, the network management system needs to send the first time to the plurality of at least one first network element. Or the at least one second network element, where the first time is used to indicate that each of the at least one first network element or the at least one second network element is to the network management system The time window for sending network management data.

Alternatively, the network management system needs to send the first threshold range to the at least one first network element or the at least one, when the network element performs the network management data transmission according to the idle resource meeting the first threshold range or various combinations thereof. a second network element, where the first threshold range is used to indicate that each of the at least one first network element or the at least one second network element sends network management data to the network management system Resources needed.

Or the network management system needs to send the second threshold range to the at least one first network element or the at least one, where the network element performs the network management data transmission according to the priority meeting the second threshold range or the various combinations thereof. a second network element, where the second threshold range is used to indicate that each of the at least one first network element or the at least one second network element sends network management data to the network management system Priority required.

Therefore, the embodiment of the present invention can reduce the condition for the network element to report the network management data to the network management system by setting the condition for sending the network management data to the network element managed by the network management system. The network management system in the heterogeneous network improves the processing capability of the network management data, and reduces the waste of communication processing resources of the heterogeneous network.
