Description

Base station management method and device Technical field

The present invention relates to the field of communications, and in particular, to a base station management method and apparatus.

Background technique

In the specification of the European Telecommunications Standards Institute (ETSI), the management structure of Network Functions Virtualization (NFV) is defined. In this management architecture, the life cycle of a virtualized network function (VNF) instance is managed by a virtual network function manager (VNF Manager, VNFM for short); a network function virtualization manager (Network Functions Virtualization Orchestrator, for short) NFVO) is responsible for the lifecycle management of network services; Network Functions Virtualization Infrastructure (NFVI) provides various available resources for VNF; Virtualised Infrastructure Manager (VIM) is responsible for control and management. The computing, storage, and networking resources provided by NFVI.

In NFV, one of the most important factors in the implementation of network function virtualization is that network function virtualization relies on the hardware resources of general-purpose devices, which can be generalized and managed in a generalized manner. The hardware resources in the base station are different from the hardware resources of the general equipment. Different vendors provide different types of base stations, which are complicated. Therefore, the base station is difficult to be generalized, and the base station needs to be managed by using a different and dedicated element management system (EMS). This will result in difficulties in unified management of different vendors and different types of base stations, thereby increasing management costs.

The physical machine includes a cloud server, and the embodiment of the present invention may be executed in the cloud server. The cloud server can include one or more processors and a memory for storing data. The memory can be used to store software programs and modules of the application software, such as the program instructions/modules corresponding to the base station management method in the embodiment of the present invention, and the processor executes various functional applications by running software programs and modules stored in the memory.

In some examples, the memory can further include memory remotely located relative to the processor, which can be connected to the cloud server over a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

1 is a base station management method according to an embodiment 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 steps S101 to S103.

In step S101, a virtual resource request sent by the virtualization unit is received, where the virtual resource request is used to indicate a virtual resource required to create a base station management unit.

In step S102, the hardware resources required to create the base station management unit are determined according to the virtual resource request and the mapping rule, where the mapping rule is a correspondence between the hardware resource and the predefined virtual resource.

In step S103, the virtualization unit and the resource allocation unit are notified to create the base station management unit according to virtual resources and hardware resources required to create the base station management unit.

According to the above-mentioned method of base station management, base stations and different types of base stations provided by different vendors do not need to be managed by multiple EMSs, but are uniformly managed by the virtualization unit. By defining the capability of the base station by using virtual resources, the virtualization unit does not need to care about the vendor providing the base station, nor does it need to care about the model of the base station, and only needs to pay attention to the virtual resources, which can realize unified management of the base station. Reduce the management cost of the base station.

In the following, the implementation details of the steps of the above method are described below.

Generally, a base station of different vendors and different models (different vendors or different models) is deployed in the communication network, and the base station may include, for example, a baseband board, a radio remote unit (RRU), a physical antenna, and the like. Resources, the hardware resources can be managed by VIM (VIM as an infrastructure management system, need to manage various types of hardware devices; or VIM is responsible for managing various types of hardware devices. Specific base stations and specific VIM, before being managed, there will be a process of docking. For example, HP's blades can be managed by ZTE's VIM or by Tencent's VIM. Before VIM management, there will be a docking and debugging between the base station and VIM. The process may include, for example, acquiring the hardware resources, allocating the hardware resources, 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 the cloud server further includes a virtual object mapping device for performing the foregoing 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 can be defined as a virtual baseband, the radio frequency capability of the base station is defined as a virtual radio frequency, and the antenna attribute of the base station is defined as a virtual antenna. The virtual baseband may include baseband attributes of the base station, for example, baseband processing capability, baseband supported mode, and virtual baseband capability to connect the virtual radio. The virtual radio may include radio frequency attributes of the base station, such as bandwidth, frequency, power, and transmit radius. The virtual antenna may include antenna attributes of the base station, such as antenna position, antenna type, number of antennas, and antenna orientation. In other embodiments, the capabilities of the base station may also include other capabilities of the base station, and may be defined as corresponding virtual resources, which is not mentioned here.

Subsequently, the virtual object mapping device receives mapping rules sent by different base stations. This step can be subdivided into three steps: In the first step, the virtual object mapping device sends a rule of predefined virtual resources to the base station. In the second step, the base station establishes a correspondence 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 apparatus receives the mapping rule sent by the base station.

The mapping rule may have, for example, the following cases: In the first case, a rule in which a single hardware is mapped to a single virtual resource. For example, a rule for mapping a baseband board to a virtual baseband; a rule for mapping an RRU to a virtual radio; a rule for mapping a physical antenna to a virtual antenna. In the second case, a rule that maps a portion of a single piece of hardware to a virtual resource. For example, a microchip of a baseband board and a virtual baseband mapping rule; an antenna in an antenna array, with a virtual antenna mapping rule. In the third case, a rule that combines multiple hardware components into a resource pool and a virtual resource. For example, a set of baseband boards form a baseband pool with a more powerful virtual baseband mapping rule. It should be noted that the mapping rules of different base stations may be the same or different. It should be noted that the mapping rule may be reported to the virtual object mapping device by using a message after the base station is started.

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

In step S101, the virtual object mapping device receives the virtual resource request sent by the virtualization unit. The virtualization unit includes a virtual network element manager and a VNFM, or includes NFVO and VNFM. In this embodiment, the virtualization unit includes NFVO and VNFM as an example. The virtual resource request is used to indicate a virtual resource required by the virtualization unit, that is, a virtual resource required to create the VNF. Step S101 can be divided into three steps: in the first step, the NFVO sends a VNF creation request to the VNFM; in the second step, the VNFM generates a virtual resource request according to the VNF creation request; and in 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 for a virtual resource required to create a VNF. The requirements for the virtual resources required to create the VNF include: the number of virtual resources required to create the VNF, and the attribute requirements for the virtual resources required to create the VNF. The number of virtual resources required to create the VNF, for example, may specify the number of virtual basebands, virtual radios, and virtual antennas, which is for a certain cell. For the attribute requirements of the virtual resources required to create the VNF, for example, the attributes of the virtual baseband, the virtual radio, and the 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 the VNF are determined according to the specific conditions of the cell controlled by the NFV. Therefore, when the condition of the cell controlled according to the NFV changes, the virtual required for creating the VNF is required. The requirements for resources will also change. It should also be noted that the virtual resource request is determined according to the requirements of the virtual resources required to create the VNF. For example, the base station capability required by the cell controlled by the NFV includes: baseband capability (baseband support GSM standard, baseband reference signal power 14 dBm, baseband resource maximum transmission power 40 dBm), radio frequency capability (RF power 40 W, bandwidth 20 MHz, support GSM standard) ), antenna properties (4 antennas, antenna type is dual-band antenna). The requirements for the virtual resources required to create the VNF are determined based on the base station capabilities described above, and the virtual resource requests are determined based on the requirements for the virtual resources required to create the VNF.

In step S102, the virtual object mapping device determines, according to the virtual resource request and the mapping rule, a hardware resource required to create the base station management unit, where the mapping rule is between a hardware resource and a predefined virtual resource. Correspondence. The step may be subdivided into the following two steps: in the first step, the virtual object mapping device determines, according to the virtual resource request, a virtual resource required to create the VNF, and generates a corresponding virtual resource ID; The virtual object mapping device determines a hardware resource required to create the VNF according to the mapping rule and a virtual resource required to create the VNF.

For example, continuing the example in step S101, the base station capability required by the cell controlled by the NFV includes: baseband capability (baseband support GSM standard, baseband reference signal power 14 dBm, baseband resource maximum transmission power 40 dBm), radio frequency capability (radio frequency power 40 W) , bandwidth 20MHz, support GSM system), antenna properties (four antennas, antenna type is dual-band antenna). The requirements for the virtual resources required to create the VNF are determined based on the base station capabilities described above, and the virtual resource requests are determined based on the requirements for the virtual resources required to create the VNF. Based on the virtual resource request, the virtual baseband, the virtual antenna, and the virtual radio required to create the VNF are determined, and the capabilities of the 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 also generates a virtual resource ID corresponding to the virtual resource required to create the VNF. 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, a virtual baseband is required to create a VNF. The properties of the virtual baseband are: baseband support GSM standard, baseband reference signal power 14dBm, baseband resource maximum transmission power 40dBm. The virtual resource ID of the virtual baseband of such number and attribute is 10001. If the virtual resource ID is fed back to the VNFM, the VNFM can know the virtual baseband information required to create the VNF, and as a basis, the VNFM will create the VNF. .

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

In step S103, the virtual object mapping apparatus notifies the virtualization unit and the resource allocation unit to create the base station management unit according to the virtual resource and hardware resources required to create the base station management unit, so as to implement management of the base station. Step S103 can be divided into the following two steps: First, the virtual object mapping device notifies the resource allocation unit to allocate the hardware resources required to create the base station management unit acquired from the base station to the virtualization unit; The virtual object mapping device notifies the virtualization unit to create the base station management unit according to the virtual resource required to create the base station management unit. The resource allocation unit is a VIM, and the allocated hardware resources are required by the VNFM (that is, hardware resources required to create the VNF), and the base station management unit is a VNF.

Regarding the first step, an example is given for the allocation of hardware resources. For example, when allocating hardware resources of a base station, first, according to the standard of the virtual baseband, a list of base stations satisfying the requirements of the system is searched. Then, according to the location of the virtual antenna, a base station of a suitable location is selected from the list of base stations. Then, the hardware resources that are not allocated by the base station are checked, and the matching requirements of the virtual baseband, the virtual radio frequency, and the virtual antenna are met according to the mapping rules of the hardware resources to the virtual resources, and if they are satisfied, they are allocated to the VNFM. If not, you can find the base station with the closest location and evaluate whether the hardware resources provided by one of the two base stations can meet the demand (select some hardware resources from the two base stations respectively). If it is satisfied, it will be allocated. If it is not satisfied, the search scope will be gradually expanded according to the principle of location. If it is still not satisfied at the end, it will fail to return the allocated hardware resources.

Since there may be a case where the hardware resource allocation fails, the virtual object mapping device transmits the result of the hardware resource allocation to the VNFM in the virtualization unit. When the hardware resource allocation is successful, sending a message that the hardware resource allocation is successful to the VNFM, and notifying the VNFM to create the VNF according to the virtual resource required to create the VNF; when the hardware resource allocation fails, sending the hardware resource allocation fails. The message to VNFM, the process ends here.

In the second step, the virtual object mapping device notifying the VNFM to create the VNF may include: the virtual object mapping device sending the virtual resource ID to the VNFM; and notifying the VNFM according to the virtual resource ID Create the VNF. After the VNFM receives the virtual resource ID, the VNFM may determine the virtual resources required to create the VNF according to the correspondence between the virtual resource ID and the virtual resource, and then the VNFM may use the virtual resources to create the VNF. At this point, the VNF is created, and the VNF can be used for unified management of different types of base stations of different manufacturers.

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

According to the above-mentioned method of base station management, base stations and different types of base stations provided by different vendors do not need to be managed by multiple EMSs, and only need to be managed uniformly in the 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 vendor providing the base station, nor does it need to pay attention to the model of the base station, and only needs to pay attention to the virtual resources, which can realize unified management of the base station. Reduce the management cost of the base station.

FIG. 2 is a method for managing a base station according to an embodiment of the present invention. The embodiment shown in FIG. 1 focuses on how the base station management unit is created. This embodiment is a management method of the base station after the base station management unit is created and the capability of the cell controlled by the NFV is changed.

As shown in FIG. 2, the steps of the base station management method are as follows in steps S201 to S204.

In step S201, the virtual object mapping device receives the updated virtual resource request sent by the virtualization unit.

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.

In step S203, the virtual object mapping apparatus notifies the resource allocation unit to allocate the updated hardware resources required by the virtualization unit acquired from the base station to the virtualization unit.

In step S204, the virtual object mapping device notifies the virtualization unit to create an updated base station management unit.

According to the foregoing method for managing a base station, when the capability of the cell changes, the virtualization unit does not need to pay attention to the vendor and model of the base station, and only needs to pay attention to the virtual resource, and modify the number and attributes of the virtual resource to adapt to the cell capability. Change. Therefore, the base station management method of this embodiment makes it easier to manage the base station when the cell capability is changed, thereby reducing the management cost.

In the following, the implementation details of the steps of the above method are described below.

In step S201, the virtual object mapping device receives the updated virtual resource request sent by the virtualization unit. The step may be divided into three steps: in the first step, the NFVO sends an updated VNF creation request to the VNFM; in the second step, the VNFM generates an updated virtual resource request according to the updated VNF creation request; 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 the embodiment shown in FIG. 1. The updated virtual resource request is determined according to the updated requirement for the virtual resource, and the updated requirement for the virtual resource is based on the updated created VNF. Request for confirmation. The process of determining the virtual resources and hardware resources required to create the updated VNF is the same as the embodiment shown in FIG. 1 and will not be described 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 is 10001, and the virtual resource ID corresponding to the virtual resource required to create the updated VNF may become 10002. It should be noted that the virtual resource and hardware resources required to create the VNF have changed due to the change of the virtual resource request. For this reason, the VNF created according to the changed virtual resource and hardware resource can adapt to the new cell. ability.

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

Before step S204, the virtual object mapping device transmits the result of the hardware resource allocation to the VNFM in the virtualization unit. When the hardware resource allocation is successful, the message that the hardware resource allocation is successful is sent to the VNFM, and step S204 is started; when the hardware resource allocation fails, the message that the hardware resource allocation fails is sent to the VNFM, and the process ends.

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 S103 of FIG. 1 except that the virtual resource ID sent by the virtual object mapping device is changed, and the corresponding VNFM can create a VNF that adapts to the new cell capability.

According to the method of the base station management, when the cell capacity changes, the virtual network element management system or the NFVO does not need to pay attention to the vendor and model of the base station, and only needs to pay attention to the virtual resources, and modify the number and attributes of the virtual resources. Can adapt to changes in community capabilities. Therefore, the base station management method of this embodiment makes it easier to manage the base station when the cell capability is changed, thereby reducing the management cost.

FIG. 3 is a method for managing a base station according to an embodiment of the present invention. In this embodiment, the creation and modification of the base station management unit is illustrated by a specific example.

As shown in FIG. 3, the base station management method includes the following steps S301 to S323.

In step S301, base station A and base station B are deployed in a communication network.

In this embodiment, the base station A may include, for example, a baseband single board (the baseband supports the LTE FDD system, the baseband reference signal power is 14 dBm, the baseband resource maximum transmission power is 40 dBm), and one RRU (radio frequency power 40 W, bandwidth 20 MHz, and LTE FDD support). Four physical antennas (antenna type is dual-frequency antenna). The base station B may include, for example, a baseband single board (the baseband supports the LTE TDD system, the baseband reference signal power is 14 dBm, the baseband resource maximum transmission power is 40 dBm), one RRU (radio frequency power 40 W, bandwidth 20 MHz, support LTE TDD system), and four physical antennas ( The antenna type is a dual-frequency antenna).

The hardware devices of the base station A and the base station B are manageable by the VIM.

In step S302, the virtual object mapping device defines a virtual resource of the base station, and defines a baseband capability, a radio frequency capability, and an antenna attribute of the base station as a virtual baseband, a virtual radio frequency, and a virtual antenna, respectively.

In step S303, the virtual object mapping device receives the mapping rule transmitted by the base station A and the base station B.

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

In step S304, the EMS or NFVO sends a VNF creation request to the VNFM.

In this embodiment, the VNF creation request includes a requirement for a virtual resource required for creating a VNF. Here, the requirement for the virtual resource is: a virtual baseband is required (the baseband supports the LTE FDD standard, the baseband reference signal power is 14 dBm, and the baseband The maximum transmission power of the resource is 40dBm), one virtual radio (40W for RF power, 20MHz for bandwidth, LTE FDD support), and four virtual antennas (the antenna type is dual-band antenna).

In step S305, according to the VNF creation request, the VNFM generates a virtual resource request.

In step S306, the virtual object mapping device receives the virtual resource request sent by the VNFM.

In this embodiment, the virtual resource request indicates a virtual resource required to create a VNF.

In step S307, according to the virtual resource request, the virtual resource required to create the VNF and the corresponding virtual resource ID are determined.

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

In step S308, the hardware resources required to create the VNF are determined according to the mapping rule and the virtual resources required to create the VNF.

The mapping rule in this embodiment refers to step S303, and the virtual resource required to create the VNF in this embodiment is referred to step S307, and thus, the hardware resource required to create the VNF in this embodiment is: a baseband. The board (the baseband supports the LTE FDD system, the baseband reference signal power is 14 dBm, the baseband resource maximum transmission power is 40 dBm), one RRU (radio power 40 W, bandwidth 20 MHz, LTE FDD support), and four physical antennas (the antenna type is a dual-band antenna).

In step S309, the virtual object mapping device notifies the VIM to acquire hardware resources required to create the VNF.

In step S310, the virtual object mapping device notifies the VIM to allocate hardware resources required to create the VNF to the VNFM.

For allocating hardware resources, first, according to the standard of the virtual baseband with the ID of 30001, the base station that satisfies the standard condition is found as the base station A. Then, the hardware resource that is not allocated in the base station A is viewed. According to the mapping rule, the virtual resource required to create the VNF can be matched with one baseband board, one RRU, and four physical antennas in the base station A. The VIM allocates one baseband board, one RRU, and four physical antennas in the base station A to the VNFM.

In step S311, the virtual object mapping device transmits the result of the hardware resource allocation to the VNFM in the virtualization unit. When the hardware resource allocation is successful, the message that the hardware resource allocation is successful is sent to the VNFM, and step S312 is started; when the hardware resource allocation fails, the message that the hardware resource allocation fails is sent to the VNFM, and the process ends.

In step S312, the virtual object mapping device sends the virtual resource ID to the VNFM.

In 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 (ie, the creation of the VNF) can be implemented, so that the VNF manages the base stations required by the cell. However, the capabilities of the cell will change over time, and the capabilities of the base station will also change. For example, if the above cell originally supports LTE FDD and now supports LTE TDD, the VNF of the management base station also needs to be changed accordingly.

In step S314, the EMS or NFVO sends an updated VNF creation request to the VNFM.

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

In step S315, the VNFM generates an updated virtual resource request according to the updated VNF creation request.

In step S316, the virtual object mapping device receives the updated virtual resource request sent by the VNFM.

In step S317, the virtual object mapping device determines, according to the updated virtual resource request, a virtual resource required to create an updated VNF, and a corresponding virtual resource ID.

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

In step S318, the virtual object mapping device determines the hardware resources required to create the updated VNF according to the mapping rule and the virtual resources required to create the updated VNF.

The mapping rule in this embodiment refers to step S303. The virtual resource required to create the updated VNF in this embodiment is referred to step S317. Therefore, the hardware resources required to create the updated VNF in this embodiment are: a baseband. The board (the baseband supports the LTE TDD system, the baseband reference signal power is 14 dBm, the baseband resource maximum transmission power is 40 dBm), one RRU (radio power 40 W, bandwidth 20 MHz, LTE TDD support), and four physical antennas (the antenna type is a dual-band antenna).

In step S319, the virtual object mapping device notifies the VIM to acquire hardware resources required to create the updated VNF.

In step S320, the virtual object mapping device notifies the VIM to allocate hardware resources required to create the updated VNF to the VNFM.

For the allocated hardware resources here, first, according to the standard of the virtual baseband with the ID of 30004, the base station that satisfies the standard condition is found as the base station B. Then, the unassigned hardware resources in the base station B are viewed. According to the mapping rule, the virtual resources required for the updated VNF can be matched with one baseband board, one RRU, and four physical antennas in the base station B.

In step S321, the virtual object mapping device transmits the result of the hardware resource allocation to the VNFM in the virtualization unit. When the hardware resource allocation is successful, the message that the hardware resource allocation is successful is sent to the VNFM, and step S322 is started; when the hardware resource allocation fails, the message that the hardware resource allocation fails is sent to the VNFM, and the process ends.

In step S322, the virtual object mapping device sends the updated virtual resource ID to the VNFM.

In 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 implemented. When the cell capability changes, the base station management unit does not need to pay attention to the specific model of the vendor and the base station that provides the base station, and only needs to change the parameters of the virtual resource. It is possible to make the updated VNF satisfy the capabilities of the current cell.
