Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various information or devices, these information should not be limited by these terms. These terms are only used to distinguish one type of information from another.

Referring to fig. 1, a flowchart of a management method according to an embodiment of the present invention is shown, where the method is applied to a first virtual network function component VNFC, and specifically includes the following steps:

step 101, if it is detected that the resource utilization rate of the second VNFC is continuously higher than the first threshold within the predetermined time, a third VNFC is established according to the configuration entry of the second VNFC.

The EPC side network element comprises: MME, SGW, PGW, SGW, each network element is used for processing signaling plane and/or service plane traffic. In the embodiment of the invention, the virtualized application of the EPC side network element signaling plane and the service plane is realized by setting a plurality of VNFCs.

Specifically, in the embodiment of the present invention, the types of VNFCs include: global VNFCs, traffic VNFCs, signaling VNFCs, and interface VNFCs. The global VNFC is a global processing unit, and the signaling VNFC is mainly used for completing service processing on a signaling plane of the network element, and the service VNFC is mainly used for completing service processing on a service plane.

In an embodiment of the present invention, the first VNFC is a global VNFC. In the operation process of each VNFC, the first VNFC detects the operation state of each VNFC and obtains the resource utilization rate of each VNFC. In an embodiment of the present invention, the resource utilization may be CPU occupancy. If the first VNFC detects that the resource utilization rate of a certain VNFC (which is the second VNFC in the embodiment of the present invention) is higher than the first threshold and continues to be higher than the first threshold for a predetermined time, the first VNFC performs an expansion operation on the second VNFC, that is, the VNFC is repeatedly engraved, and a new VNFC, that is, a third VNFC is added.

Specifically, in the embodiment of the present invention, the first VNFC retrieves a locally stored configuration table entry corresponding to the second VNFC, and establishes the third VNFC according to the configuration table entry.

Step 102, updating the arrangement order of the VNFCs in the resource list according to the load states of all current VNFCs, so that a new user accessing an evolved packet core EPC to which the first VNFC belongs is connected to a third VNFC located at the head of the resource list.

Specifically, in the embodiment of the present invention, the first VNFC obtains a load state of each VNFC, where the load state may be the number of access users of each VNFC. And the first VNFC updates the arrangement sequence of the VNFCs in the resource list according to the acquired load state of the VNFCs. In the embodiment of the present invention, since the third VNFC is a newly established VNFC, and its load status is zero, the third VNFC will be located at the first position in the updated resource list.

When a newly accessed user exists in the EPC of the first VNFC, the corresponding VNFC may select a VNFC that needs to be accessed for the new user according to a new user requirement. When a VNFC connected to a new user is selected, the corresponding VNFC acquires the resource list from the first VNFC, and designates a third VNFC located at the head of the resource list, that is, a VNFC with the least load state, as the VNFC connected to the new user.

Step 103, if it is detected that the resource utilization rate of the fourth VNFC is continuously lower than the second threshold within the predetermined time, performing a deletion operation on the fourth VNFC.

Specifically, in the embodiment of the present invention, if the first VNFC detects that the resource utilization rate of a certain VNFC (in the embodiment of the present invention, the VNFC is a fourth VNFC) is lower than the second threshold and is continuously lower than the second threshold for a predetermined time, the first VNFC performs a deletion operation on the fourth VNFC, so as to save resource occupation and reduce system load.

In summary, in the technical solution in the embodiment of the present invention, if it is detected that the resource utilization rate of the second VNFC is continuously higher than the first threshold within the predetermined time, a third VNFC is established according to the configuration entry of the second VNFC; updating the arrangement sequence of the VNFCs in the resource list according to the load states of all the VNFCs at present so as to enable a new user accessed to an Evolved Packet Core (EPC) to which the first VNFC belongs to be connected with a third VNFC located at the first position of the resource list; and if the resource utilization rate of the fourth VNFC is detected to be continuously lower than the second threshold value within the preset time, executing deletion operation on the fourth VNFC. Therefore, dynamic management of the VNFC is realized, the resource utilization rate and the system performance are effectively improved, and further the user experience is improved.

In addition, in a preferred embodiment of the present invention, the step of establishing the third VNFC according to the configuration entry of the second VNFC specifically includes:

acquiring the resource utilization rate of all VNFCs;

monitoring the resource utilization rate of all VNFCs in real time; alternatively, the resource utilization information transmitted by all VNFCs at predetermined intervals is received.

In order that those skilled in the art will better understand the management method of the present invention, the following detailed description will be given with reference to specific examples.

(1) A VNFC process is created.

In the embodiment of the present invention, before each VNFC is created, configuration parameters of the VNFC need to be set. Configuration parameters include, but are not limited to: the service type of the VNFC, the network element function type, the occupied memory, the number of CPU cores to be occupied, the size of the required hard disk and the like.

For example, the following steps are carried out: if a signaling plane VNFC of the MME network element needs to be established, the service type of the VNFC is a signaling VNFC, the network element function type is an MME network element function, the occupied memory is 4G, the number of CPU cores is 2, and the size of the required hard disk is 50G. The user may set configuration parameters in a VNFM (virtual network function manager).

In addition, the user needs to set the number of VNFCs to be configured and whether the VNFCs are scalable, and the scalable number. In other embodiments, whether or not it is extensible and the amount of the extension may also be automatically set by the VNFM.

Still take the VNFC of the signaling plane of the MME network element as an example for explanation: the configuration number of the VNFCs is set to 2, and is scalable, and the scalable number is 2.

After configuring all the VNFCs to be established, the VNFM establishes a VNFC number configuration entry according to the user setting, as shown in table one, and a resource configuration entry, as shown in table two.

Watch 1

Watch two

Wherein, whether expandable is represented by 0/1, 0 represents non-expandable, and 1 represents expandable.

After the configuration is completed, the VNFM starts each VNFC in sequence according to the sequence in the configuration table. In an embodiment of the present invention, after each VNFC is started, a registration request is sent to the global VNFC. In one embodiment, if there is a VNFC that completes before the global VNFC is established, the VNFC of this type periodically sends a registration request after startup until the global VNFC returns a registration response to the VNFC after startup.

The signaling VNFC of the MME network element is also described in detail above as an example: after the VNFC is started, the VNFC registers to the global VNFC. In the registration process, the VNFC reports its configuration information to the global VNFC. That is, configuration information such as configuration parameters and the number when the VNFC is established is sent to the global VNFC. And the global VNFC acquires the configuration information reported by the VNFC and writes the configuration information into a resource list. In one embodiment of the invention, the global VNFC may establish respective resource lists for different types of network elements. In another embodiment of the present invention, the global VNFC may write all VNFCs into the same resource list and classify the VNFCs according to different network element types, as shown in table three.

Watch III

The identification information is information which is issued by the signaling or service VNFC and is used for uniquely identifying the VNFC after the signaling or service VNFC is registered with the global VNFC. It should be noted that, the information in the table is only for making those skilled in the art better understand the VNFC creating process of the present invention, and the user can self-define the items in the table and the content of the required record according to the actual requirement, which is not limited by the present invention.

(2) The VNFC process is dynamically increased.

In the operation process of the VNFC, the global VNFC acquires the resource utilization rate of all the VNFCs. In the embodiment of the invention, the resource utilization rate is the CPU occupancy rate. The method for acquiring the resource utilization rate of each VNFC by the global VNFC may include one of the following: monitoring the resource utilization rate of all VNFCs in real time; alternatively, the resource utilization information transmitted by all VNFCs at predetermined intervals is received. In another embodiment of the present invention, the VNFM may also obtain resource utilization rates of the VNFCs and synchronize the resource utilization rates to the global VNFC, which is not limited in the present invention.

And if the CPU occupancy rate of a certain VNFC exceeds a first threshold value and is continued in a preset time, the global VNFC executes an expansion flow. In the embodiment of the present invention, the user may set the first threshold and the predetermined time according to the actual requirement and the system status, which is not limited in the present invention.

Specifically, the extension flow is as follows:

the signaling plane VNFC of the MME network element is taken as an example for detailed illustration, and is hereinafter referred to as signaling VNFC 1.

The global VNFC retrieves the resource list and obtains resource configuration information (i.e., configuration table entry in the embodiment of the present invention) related to the signaling VNFC 1. And detecting whether the signaling VNFC1 is expandable or not according to the acquired configuration table item. The extendable default parameter is 1 and the number currently extended does not exceed the upper limit of the extendable number.

If the expandable is determined, the global VNFC detects whether the current system resource supports establishing a third VNFC. I.e. to determine whether system resources are sufficient. If yes, the signaling VNFC3 is established according to the configuration parameters in the configuration table entry. After the signaling VNFC is started, registration is performed on the global VNFC, and a specific registration process is the same as the steps in the above embodiment, which is not described herein again. After successful registration, the global VNFC allocates unique VNFC identification information to the signaling VNFC 3. In the configuration process, the number of VNFC configurations of the signaling plane of the MME network element function is 2, that is, the signaling VNFC1 and the signaling VNFC2, so that the extended VNFC is the signaling VNFC 3.

(3) And a service access process of the dynamically added VNFC.

And the global VNFC updates the arrangement sequence of the VNFCs in the resource list according to the load states of all the VNFCs at present. In the embodiment of the present invention, the load status is the number of users accessing. In the embodiment of the present invention, in the process of allocating users, each VNFC allocates traffic according to the number of users (i.e., the load status in the embodiment of the present invention) of the VNFC that have accessed. For example, the following steps are carried out: when the interface VNFC allocates a new access user, the number of the accessed users of the current MME network element signaling VNFC is obtained from the global VNFC, and the new access user is allocated to the MME network element signaling VNFC with the least number of the accessed users.

In the embodiment of the present invention, if the resource list in the global VNFC is shown in table three, the VNFCs are sorted according to different function types. In the update process of the global VNFC, since the newly added VNFC has the least load, the VNFC will be located at the first position of the VNFC arrangement order under the function type to which the VNFC belongs.

In order to make the service access process of the dynamically added VNFC better understood by those skilled in the art, the following detailed description is made in terms of specific embodiments:

1) the newly added VNFC is a signaling VNFC3 of the MME network element.

When a new user accesses the EPC network, the interface VNFC acquires a resource list of each VNFC under the MME network element function type from the global VNFC. Currently, the signaling VNFC3 is located at the head of the resource list, that is, the load state is the least, the interface VNFC selects the signaling VNFC3 to connect with the new access user, and records the corresponding relationship between the new user and the signaling VNFC3, so as to interact with the signaling VNFC3 about the new access user through the corresponding relationship.

2) The newly added VNFC is a signaling VNFC4 of the SGW network element.

And when a new user accesses, the signaling VNFC of the MME network element acquires a resource list of each VNFC under the function type of the SGW network element from the global VNFC. Currently, the signaling VNFC4 is located at the head of the resource list. Signaling VNFC selection signaling VNFC4 of the MME network element connects with the new access user, and assigns a TEIDc (Tunnel End Point identity) to the user, where the TEIDc includes but is not limited to: the global VNFC allocates unique identification information to the signaling VNFC4 and user identification information of the new access user, where the user identification information is used to uniquely identify the user. And the signaling VNFC of the MME network element and the signaling VNFC of the SGW network element perform signaling message interaction aiming at the new access user according to the TEIDc. For example, the following steps are carried out: and the VNFC of the MME network element sends the signaling message of the new user to the VNFC of the corresponding SGW network element according to the VNFC identification information in the TEIDc. The VNFC of the SGW network element also carries the TEIDc when returning the signaling message to the VNFC of the MME network element, so that the VNFC of the MME network element can recognize that the message is for the new access user when receiving the signaling message carrying the TEIDc. Details of information interaction between the VNFCs of the MME network element and the VNFCs of the SGW network element are the same as those in the embodiment of the prior art, and are not described herein again.

3) The newly added VNFC is the service VNFC 3.

In the embodiment of the present invention, the service VNFC may be commonly used by VNFCs under a plurality of different network element functions. And when a new user accesses, the signaling VNFC of the SGW network element acquires a resource list of the service VNFC from the global VNFC. Currently, the new service VNFC3 is located at the head of the resource list. A signaling VNFC selection service VNFC3 of the SGW network element connects to a new access user, and allocates a TEIDu (Tunnel End Point Identifier user) to the new access user, where the TEIDu includes, but is not limited to: the global VNFC allocates unique VNFC identification information to the service VNFC3 and bearer information of the new access user, where the bearer information includes, but is not limited to, information identifying a logical channel carrying user traffic. The signaling VNFC of the PGW network element obtains a resource list of the service VNFCs from the global VNFC, and also selects the service VNFC3 located at the head to connect with the new access user to process the PGW service message of the new access user, and the PGW also allocates TEIDu to the service VNFC 3. In the subsequent information interaction process, information interaction is performed between the VNFC of the SGW network element and the VNFC of the PGW network element and the service VNFC3 according to TEIDu. The details are similar to those in the prior art embodiment and are not described herein.

(4) The VNFC process is dynamically deleted.

And if the CPU occupancy rate of a certain VNFC is lower than a second threshold value and is continued in a preset time, the global VNFC executes deletion operation on the VNFC. In the embodiment of the present invention, the user may set the second threshold and the predetermined time according to the actual requirement and the system state, which is not limited in the present invention. In an embodiment of the invention, the VNFCs available for dynamic deletion are extended VNFCs.

Specifically, the deletion process is as follows:

The global VNFC marks the state of the signaling VNFC1 in the resource list as a delayed blocking state, and deletes resource information (information such as resource usage and resource configuration in the embodiment of the present invention) corresponding to the signaling VNFC1 in the resource list, so that other VNFCs cannot acquire the resource information of the signaling VNFC1, and thus no new service is allocated to the signaling VNFC 1.

After the VNFC1 processes its own traffic, the connected users are released one by one. After detecting that the signaling VNFC1 is released, the global VNFC removes the signaling VNFC1 from the resource list, and recovers the resources occupied by the signaling VNFC 1.

In summary, in the technical solution in the embodiment of the present invention, if it is detected that the resource utilization rate of the second VNFC is continuously higher than the first threshold within the predetermined time, a third VNFC is established according to the configuration entry of the second VNFC; updating the arrangement sequence of the VNFCs in the resource list according to the load states of all the VNFCs at present so as to enable a new user accessed to an Evolved Packet Core (EPC) to which the first VNFC belongs to be connected with a third VNFC located at the first position of the resource list; and if the resource utilization rate of the fourth VNFC is detected to be continuously lower than the second threshold value within the preset time, executing deletion operation on the fourth VNFC. Therefore, dynamic addition and deletion of the VNFC in the EPC side virtualization environment are achieved, the newly added VNFC effectively acts in the virtualization environment, namely the access process of the newly added VNFC is achieved, the flexibility and the usability of the virtualization system are improved, the resource utilization rate and the system performance of the system are improved, and the user experience is improved.
