Embodiment one

FIG. 1 is a base station management method provided in Embodiment 1 of the present invention. The base station management method is applied to a cloud server. As shown in FIG. 1 , the base station management method includes:

Step S101: receiving a virtual resource request sent by the virtualization unit, the virtual resource request is used to indicate the creation of virtual resources required by the base station management unit;

Step S102: According to the virtual resource request and mapping rules, determine the hardware resources required to create the base station management unit, wherein the mapping rules are the correspondence between hardware resources and predefined virtual resources;

Step S103: Notify the virtualization unit and the resource allocation unit to create the base station management unit according to the virtual resources and hardware resources required for creating the base station management unit, so as to realize the management of the base station.

According to the above base station management method, base stations provided by different manufacturers and base stations of different models do not need to be managed by multiple EMSs, but are managed uniformly by the virtualization unit. By defining the capabilities of the base station in the form of virtual resources, the virtualization unit does not need to care about the manufacturer of the base station, nor does it need to care about the model of the base station, but only needs to pay attention to the virtual resources, which can realize the unified management of the base station. Reduce the management cost of the base station.

The implementation details of each step of the above method are as follows:

Usually, base stations of different manufacturers and different models (different manufacturers or different models) are deployed in the communication network, and the base stations may include hardware such as a baseband board, a radio remote unit (Radio Remote Unit, RRU for short), physical antennas, etc. resources, the hardware resources can be managed by VIM (VIM is an infrastructure management system, which needs to manage various types of hardware devices; in other words, VIM is responsible for managing various types of hardware devices. Specific base stations and specific Before the VIM is managed, there will be a docking process. For example, HP’s blades can be managed by ZTE’s VIM, and can also be managed by Tencent’s VIM. Before the VIM is managed, there will be a docking and debugging between the base station and the VIM process), the management may include, for example, obtaining the hardware resource, allocating the hardware resource, and the like. The virtualization unit, the resource allocation unit, and the base station management unit in the above method are located in the cloud server, and meanwhile, the cloud server also includes a virtual object mapping device for performing the above steps.

Before step S101, the virtual object mapping device first defines the capabilities and attributes of the base station as corresponding virtual resources, which are predefined virtual resources. Specifically, for example, the baseband capability of the base station may be defined as a virtual baseband, the radio frequency capability of the base station may be defined as a virtual radio frequency, and the antenna property of the base station may be defined as a virtual antenna. Wherein, the virtual baseband may include baseband attributes of the base station, for example, baseband processing capability, standards supported by the baseband, and capability of connecting the virtual baseband to the virtual radio frequency. The virtual radio frequency may include radio frequency properties of the base station, for example, bandwidth, frequency point, power, and transmission radius. The virtual antenna may include antenna properties of the base station, for example, antenna position, antenna type, antenna number, and antenna orientation. In other embodiments, the capabilities of the base station may also include. . . . . . , and can be defined as corresponding virtual resources.

Subsequently, the virtual object mapping device receives mapping rules sent by different base stations. This step can be subdivided into two steps: in the first step, the virtual object mapping device sends the rules of predefined virtual resources to the base station. In the second step, the base station formulates a corresponding relationship between the predefined virtual resources and the hardware resources of the base station according to the rules of the predefined virtual resources, and the corresponding relationship is a mapping rule. In a third step, the virtual object mapping device receives the mapping rule sent by the base station.

The mapping rules may, for example, have the following situations: the first situation is a rule for mapping a single hardware to a single virtual resource. For example, the mapping rule between a baseband single board and a virtual baseband; the mapping rule between an RRU and a virtual radio frequency; the mapping rule between a physical antenna and a virtual antenna. In the second case, rules that map a portion of a single piece of hardware to a virtual resource. For example, a microchip of a baseband single board is mapped to a virtual baseband; an antenna in an antenna array is mapped to a virtual antenna. In the third case, a rule for mapping multiple hardware resource pools to a virtual resource. For example, a group of baseband single boards forms a baseband pool and a virtual baseband mapping rule with strong capabilities. It should be noted that the mapping rules of different base stations may be the same or different. It should also be noted that the mapping rule may be reported to the virtual object mapping device in the form of a message after the base station is activated.

After the above steps are completed, step S101 will be executed.

In step S101, the virtual object mapping device receives a virtual resource request sent by a virtualization unit. Wherein, the virtualization unit includes a virtual network element manager and a VNFM, or includes an NFVO and a VNFM. In this embodiment, the NFVO and the VNFM are taken as examples for illustration. The virtual resource request is used to indicate the virtual resources required by the virtualization unit, that is, the virtual resources required to create the VNF. Step S101 can be divided into three steps: the first step, the NFVO sends a VNF creation request to the VNFM; the second step, the VNFM generates a virtual resource request according to the VNF creation request; the third step, the virtual object The mapping device receives the virtual resource request sent by the VNFM.

The VNF creation request includes: a requirement on virtual resources needed to create the VNF. The requirements on the virtual resources required for creating the VNF include: requirements for the number of virtual resources required for creating the VNF, and requirements for the attributes of the virtual resources required for creating the VNF. Wherein, the requirement on the number of virtual resources required for creating a VNF, for example, may specify the number of virtual baseband, virtual radio frequency, and virtual antenna, which is for a certain cell. Requirements on the attributes of virtual resources required to create a VNF, for example, attributes of virtual baseband, virtual radio frequency, and virtual antenna can be specified, which is for a certain virtual resource. It should be noted that the requirements for the virtual resources required to create a VNF are determined according to the specific conditions of the cells controlled by the NFV. Therefore, when the conditions of the cells controlled by the NFV change, the virtual Resource requirements also change. It should also be noted that the virtual resource request is determined according to the requirements on the virtual resources needed to create the VNF. For example, the base station capabilities required by the cell controlled by the NFV include: baseband capability (baseband supports GSM standard, baseband reference signal power 14dBm, baseband resource maximum transmission power 40dBm), radio frequency capability (radio frequency power 40W, bandwidth 20MHz, support GSM standard ), antenna attributes (the number of antennas is 4, and the antenna type is dual-frequency antenna). The requirement for the virtual resources required for creating the VNF is determined according to the capability of the base station, and the virtual resource request is determined according to the requirement for the virtual resources required for creating the VNF.

In step S102, the virtual object mapping device determines the hardware resources needed to create the base station management unit according to the virtual resource request and the mapping rule, wherein the mapping rule is between the hardware resource and the predefined virtual resource corresponding relationship. This step can be subdivided into the following two steps: first step, the virtual object mapping device determines the virtual resource required to create the VNF according to the virtual resource request, and generates a corresponding virtual resource ID; second step, The virtual object mapping device determines hardware resources required to create the VNF according to the mapping rule and the virtual resources required to create the VNF.

For example, continuing the example in step S101, the base station capabilities required by the cell controlled by the NFV include: baseband capability (baseband supports GSM standard, baseband reference signal power 14dBm, baseband resource maximum transmission power 40dBm), radio frequency capability (radio frequency power 40W , bandwidth 20MHz, support GSM system), antenna attributes (the number of antennas is 4, and the antenna type is dual-band antenna). The requirement for the virtual resources required for creating the VNF is determined according to the capability of the base station, and the virtual resource request is determined according to the requirement for the virtual resources required for creating the VNF. According to the virtual resource request, determine the virtual baseband, virtual antenna and virtual radio frequency required to create the VNF, and the capabilities of these virtual resources are the capabilities that the base station required by the cell controlled by the NFV should have.

At the same time, the virtual object mapping device will also generate a virtual resource ID corresponding to the virtual resource required to create the VNF. Wherein, the virtual resource ID is used by the virtual object mapping device to feed back to the VNFM, so that the VNFM knows the number and attributes of the virtual resources required to create the VNF. For example, creating a certain VNF requires a virtual baseband, and the attributes of the virtual baseband are: the baseband supports the GSM standard, the baseband reference signal power is 14dBm, and the maximum transmission power of baseband resources is 40dBm. The virtual resource ID of the virtual baseband with such number and attributes is 10001. If the virtual resource ID is fed back to the VNFM, the VNFM will be able to know the information of the virtual baseband required to create this VNF. Based on this, the VNFM will create the VNF .

The mapping rule indicates the correspondence between the predefined virtual resources and the hardware devices of the base station, and the number and attributes of the virtual resources required to create the VNF can be known, so the hardware resources required to create the VNF can also be known . For example, the mapping rule is the mapping rule between a baseband single board and a virtual baseband, and the virtual resource required to create a VNF is: a virtual baseband, and the attributes of the virtual baseband are: the baseband supports GSM standard, the baseband reference signal power is 14dBm, and the baseband resource is the largest The transmission power is 40dBm. At this point, the hardware resources required to create a VNF are: a baseband board, and the attributes of the hardware board are: the baseband supports the GSM standard, the baseband reference signal power is 14dBm, and the maximum transmission power of the baseband resources is 40dBm.

In step S103, the virtual object mapping device notifies the virtualization unit and the resource allocation unit to create the base station management unit according to the virtual resources and hardware resources required for creating the base station management unit, so as to realize the base station management unit manage. Step S103 can be divided into the following two steps: the first step, the virtual object mapping device notifies the resource allocation unit to obtain from the base station the hardware resources required to create the base station management unit and allocate them to the virtualization unit; the second step, the The virtual object mapping device notifies the virtualization unit to create the base station management unit according to the virtual resources required for creating the base station management unit. Wherein, the resource allocation unit is a VIM, the allocated hardware resources are required by the VNFM (that is, the hardware resources required for creating the VNF), and the base station management unit is a VNF.

Regarding the first step, for allocating hardware resources, an example will be given to describe in detail. For example, when allocating hardware resources of the base station, firstly, according to the standard of the virtual baseband, a list of base stations meeting the standard requirements is searched. Then, according to the position of the virtual antenna, select a suitable base station from the list of base stations. Then check the unallocated hardware resources of the base station, and match whether the requirements of virtual baseband, virtual radio frequency, and virtual antenna are met according to the mapping rules from hardware resources to virtual resources. If so, allocate VNFM. If not, you can search for the closest base station, and evaluate whether the hardware resources provided by the two base stations can meet the requirements (select a part of the hardware resources from the two base stations respectively). If it is satisfied, it will be allocated; if it is not satisfied, the search range will be gradually expanded according to the principle of the closest position. If it is still unsatisfactory in the end, it will return failure to allocate hardware resources.

Since hardware resource allocation may fail, the virtual object mapping device will send the result of hardware resource allocation to the VNFM in the virtualization unit. When the hardware resource allocation is successful, send a message that the hardware resource allocation is successful to the VNFM, and notify the VNFM to create the VNF according to the virtual resources required for creating the VNF; when the hardware resource allocation fails, send a hardware resource allocation failure message The message is sent to VNFM, and the process ends here.

Regarding the second step, the virtual object mapping device notifies the VNFM to create a VNF, which may specifically include: the virtual object mapping device sends the virtual resource ID to the VNFM; and notifies the VNFM to create a VNF according to the virtual resource ID Create the VNF. After the VNFM receives the virtual resource ID, the VNFM can determine the virtual resources needed to create the VNF according to the correspondence between the virtual resource ID and the virtual resources, and then the VNFM can use these virtual resources to create the VNF. So far, the VNF is created, and the VNF can be used to uniformly manage base stations of different manufacturers and models.

After step S103, the VNFM sends the result of creating the VNF to the NFVO, and at the same time, it also needs to send information about the virtual baseband, virtual radio frequency, and virtual antenna required to create the VNF to the NFVO. Therefore, the NFVO can view the information of the virtual baseband, virtual radio frequency, and virtual antenna.

According to the above base station management method, base stations of different manufacturers and base stations of different models do not need to be managed by multiple EMSs, but only need to be managed in a unified manner in NFV. By defining the capabilities of the base station using virtual resources, the virtual network element management system or NFVO does not need to care about the manufacturer that provides the base station, nor does it need to pay attention to the model of the base station, but only needs to pay attention to the virtual resources, which can realize the unified management of the base station , to reduce the management cost of the base station.

Embodiment two

Fig. 2 is a base station management method provided by Embodiment 2 of the present invention, and Embodiment 2 is a further improvement on Implementation 1. Embodiment 1 mainly explains how the base station management unit is created, and embodiment 2 is the management method of the base station after the base station management unit is created and the capability of the cell controlled by NFV changes. As shown in Figure 2, the steps of the base station management method are as follows:

Step S201: the virtual object mapping device receives the updated virtual resource request sent by the virtualization unit;

Step S202: The virtual object mapping device determines updated virtual resources and hardware resources required by the virtualization unit according to the mapping rule and the updated virtual resource request;

Step S203: the virtual object mapping device notifies the resource allocation unit to allocate the updated hardware resource required by the virtualization unit obtained from the base station to the virtualization unit;

Step S204: the virtual object mapping device notifies the virtualization unit to create an updated base station management unit.

According to the above base station management method, when the capacity of the cell changes, the virtualization unit does not need to pay attention to the manufacturer and model of the base station, but only needs to pay attention to the virtual resources, and modify the number and attributes of the virtual resources to adapt to the capacity of the cell. change. Therefore, the base station management method of this embodiment makes base station management more convenient when cell capabilities change, thereby reducing management costs.

The implementation details of each step of the above method are as follows:

In step S201, the virtual object mapping device receives an updated virtual resource request sent by a virtualization unit. This step can be divided into three steps: the first step, the NFVO sends an updated VNF creation request to the VNFM; the second step, the VNFM generates an updated virtual resource request according to the updated VNF creation request; the third Step, the virtual object mapping device receives the updated virtual resource request sent by the VNFM.

In step S202, the virtual object mapping device determines the updated virtual resource and hardware resource required by the virtualization unit according to the mapping rule and the updated virtual resource request. The mapping rule is exactly the same as that in Embodiment 1, the updated virtual resource request is determined according to the updated virtual resource requirement, and the updated virtual resource requirement is determined according to the updated VNF creation request. The process of determining the virtual resources and hardware resources required to create the updated VNF is the same as that in Embodiment 1, and will not be repeated here. Since the virtual resource request changes, the virtual resource required to create the updated VNF changes, and the virtual resource ID corresponding to the virtual resource also changes. For example, the virtual resource ID corresponding to the virtual resource required to create the VNF originally is 10001, but now the virtual resource corresponding to the virtual resource required to create the updated VNF may become 10002. It should be noted that due to the change of the virtual resource request, the virtual resources and hardware resources required to create the VNF have changed, and for this reason, the VNF created according to the changed virtual resources and hardware resources can adapt to the new community ability.

In step S203, the virtual object mapping device notifies the resource allocation unit to allocate the updated hardware resource required by the virtualization unit acquired from the base station to the virtualization unit. This step is partly similar to step S103, except that the hardware resources acquired and allocated by the VIM are changed.

Before step S204, the virtual object mapping device sends the hardware resource allocation result to the VNFM in the virtualization unit. When the hardware resource allocation is successful, send a message of hardware resource allocation success to the VNFM, and start to execute step S204; when the hardware resource allocation fails, send a hardware resource allocation failure message to the VNFM, and the process ends here.

In step S204, the virtual object mapping device notifies the virtualization unit to create an updated base station management unit. This step is similar to step S106, except that when the virtual resource ID sent by the virtual object mapping device changes, the corresponding VNFM can create a VNF adapting to the new cell capability.

According to the above base station management method, when the capability of the cell changes, the virtual network element management system or NFVO does not need to pay attention to the manufacturer and model of the base station, but only needs to pay attention to the virtual resources, and modify the number and attributes of the virtual resources. Ability to adapt to changes in cell capabilities. Therefore, the base station management method of this embodiment makes base station management more convenient when cell capabilities change, thereby reducing management costs.

Embodiment three

Fig. 3 is a base station management method provided by Embodiment 3 of the present invention, and Embodiment 3 is a further improvement on Embodiment 1 and Embodiment 2. In this embodiment, the creation and modification of the base station management unit are described through specific examples. As shown in Figure 3, the base station management method includes the following steps:

Step S301: Deploy base station A and base station B in the communication network.

In this embodiment, the base station A may include, for example, a baseband single board (the baseband supports the LTEFDD system, the baseband reference signal power is 14dBm, and the maximum transmission power of the baseband resources is 40dBm), an RRU (radio frequency power is 40W, the bandwidth is 20MHz, and the LTEFDD system is supported), Four physical antennas (antenna type is dual-band antenna). Base station B may include, for example, a baseband single board (the baseband supports the LTE TDD system, the baseband reference signal power is 14dBm, and the maximum transmission power of the baseband resource is 40dBm), an RRU (the radio frequency power is 40W, the bandwidth is 20MHz, and the LTETDD system is supported), four physical antennas ( Antenna type is dual-band antenna).

Wherein, the hardware devices of the base station A and the base station B can be managed by the VIM.

Step S302: The virtual object mapping device defines virtual resources of the base station, and defines baseband capability, radio frequency capability and antenna attributes of the base station as virtual baseband, virtual radio frequency and virtual antenna respectively.

Step S303: The virtual object mapping device receives the mapping rules sent by base station A and base station B.

In this embodiment, the mapping rule is that one baseband board is mapped to one virtual baseband, one RRU is mapped to one virtual radio frequency, and one physical antenna is mapped to one virtual antenna.

Step S304: EMS or NFVO sends a VNF creation request to VNFM.

In this embodiment, the VNF creation request includes the requirements for virtual resources needed to create the VNF. Here, the requirements for virtual resources are: a virtual baseband (baseband supports LTEFDD standard, baseband reference signal power 14dBm, baseband The maximum transmission power of resources is 40dBm), one virtual radio frequency (radio frequency power 40W, bandwidth 20MHz, supporting LTE FDD standard), four virtual antennas (antenna type is dual-band antenna).

Step S305: According to the VNF creation request, the VNFM generates a virtual resource request.

Step S306: the virtual object mapping device receives the virtual resource request sent by the VNFM.

In this embodiment, the virtual resource request indicates the virtual resources needed to create the VNF.

Step S307: According to the virtual resource request, determine the virtual resource required to create the VNF and the corresponding virtual resource ID.

The virtual resource required by the VNF in this embodiment is a virtual baseband (the baseband supports the LTEFDD standard, the baseband reference signal power is 14dBm, the maximum transmission power of the baseband resource is 40dBm, and the ID is 30001), a virtual radio frequency (radio frequency power 40W, bandwidth 20MHz, Support LTEFDD standard, ID is 30002), four virtual antennas (antenna type is dual-band antenna, ID is 30003).

Step S308: According to the mapping rule and the virtual resources required for creating the VNF, determine the hardware resources required for creating the VNF.

Refer to step S303 for the mapping rules in this embodiment, and refer to step S307 for the virtual resources required to create the VNF in this embodiment. It can be seen that the hardware resources required to create the VNF in this embodiment are: a baseband Single board (baseband supports LTEFDD standard, baseband reference signal power 14dBm, maximum transmission power of baseband resources 40dBm), one RRU (radio frequency power 40W, bandwidth 20MHz, support LTEFDD standard), four physical antennas (antenna type is dual-frequency antenna).

Step S309: the virtual object mapping device notifies the VIM to obtain hardware resources required for creating the VNF.

Step S310: the virtual object mapping device notifies the VIM to allocate hardware resources required for creating the VNF to the VNFM.

For allocating hardware resources, firstly, according to the standard of the virtual baseband with ID 30001, it is found that the base station that satisfies the standard condition is base station A. Secondly, check the unallocated hardware resources in base station A, and find that the virtual resources required to create the VNF can match one baseband single board, one RRU and four physical antennas in base station A according to the mapping rules. The VIM allocates one baseband board, one RRU and four physical antennas in base station A to the VNFM.

Step S311: the virtual object mapping device sends the hardware resource allocation result to the VNFM in the virtualization unit. When the hardware resource allocation is successful, send a hardware resource allocation successful message to the VNFM, and start to execute step S312; when the hardware resource allocation fails, send a hardware resource allocation failure message to the VNFM, and the process ends here.

Step S312: the virtual object mapping device sends the virtual resource ID to the VNFM.

Step S313: the virtual object mapping device notifies the VNFM to create the VNF according to the virtual resource ID.

Through the above steps, the creation of the base station management unit (that is, the creation of the VNF) can be realized, so that the VNF manages the base stations required by the cell. However, the capability of the cell will change with the passage of time, and at this time, the capability of the base station is also required to change. For example, the above-mentioned cell originally supported LTE FDD, but now supports LTE TDD, and the VNF that manages the base station also needs to be changed accordingly.

Step S314: EMS or NFVO sends an updated VNF creation request to VNFM.

In this embodiment, the updated VNF creation request includes specifying an updated requirement for the virtual resource. Here, the updated requirement for the virtual resource is: requiring a virtual baseband (the baseband supports the LTE TDD system, the baseband Reference signal power 14dBm, maximum transmission power of baseband resources 40dBm), one virtual radio frequency (radio frequency power 40W, bandwidth 20MHz, support LTE TDD standard), four virtual antennas (antenna type is dual-band antenna). That is, the cell changes from originally supporting LTE FDD to currently supporting LTE TDD.

Step S315: According to the updated VNF creation request, the VNFM generates an updated virtual resource request.

Step S316: the virtual object mapping device receives the updated virtual resource request sent by the VNFM.

Step S317: The virtual object mapping device determines the virtual resource required to create the updated VNF and the corresponding virtual resource ID according to the updated virtual resource request.

In this embodiment, the virtual resources required to create an updated VNF are: a virtual baseband (baseband supports LTEFDD standard, baseband reference signal power 14dBm, baseband resource maximum transmission power 40dBm, ID is 30004), a virtual radio frequency (radio frequency power 40W , bandwidth 20MHz, support LTEFDD standard, ID is 30005), four virtual antennas (antenna type is dual-band antenna, ID is 30003).

Step S318: The virtual object mapping device determines the hardware resources required for creating the updated VNF according to the mapping rule and the virtual resources required for creating the updated VNF.

Refer to step S303 for the mapping rules in this embodiment, and refer to step S317 for the virtual resources required to create an updated VNF in this embodiment. It can be seen that the hardware resources required to create an updated VNF in this embodiment are: a baseband Single board (baseband supports LTETDD system, baseband reference signal power 14dBm, maximum transmission power of baseband resources 40dBm), one RRU (radio frequency power 40W, bandwidth 20MHz, supports LTETDD system), four physical antennas (antenna type is dual-frequency antenna).

Step S319: the virtual object mapping device notifies the VIM to obtain the hardware resources required for creating the updated VNF.

Step S320: the virtual object mapping device notifies the VIM to allocate hardware resources required for creating the updated VNF to the VNFM.

For the allocation of hardware resources here, firstly, according to the standard of the virtual baseband whose ID is 30004, it is found that the base station that satisfies the standard condition is base station B. Secondly, check the unallocated hardware devices in base station B, and find that the virtual resources required by the updated VNF can match one baseband single board, one RRU and four physical antennas in base station B according to the mapping rules.

Step S321: the virtual object mapping device sends the hardware resource allocation result to the VNFM in the virtualization unit. When the hardware resource allocation is successful, send a hardware resource allocation successful message to the VNFM, and start to execute step S322; when the hardware resource allocation fails, send a hardware resource allocation failure message to the VNFM, and the process ends here.

Step S322: the virtual object mapping device sends the updated virtual resource ID to the VNFM.

Step S323: the virtual object mapping device notifies the VNFM to create the updated VNF according to the updated virtual resource ID.

Through the above steps, the modification of the base station management unit (that is, the modification of the VNF) can be realized. When the cell capability changes, the base station management unit does not need to pay attention to the specific manufacturer and model of the base station, as long as the parameters of the virtual resources are changed. Then the updated VNF can meet the capabilities of the current cell.

Therefore, the base station management method of this embodiment can manage the base stations in a unified manner without being limited by the differences between the base stations, thereby reducing the management cost.
