Description
Technical Field
The present invention relates to a sharing method, and more particularly, to a user plane function network element sharing method, medium, and electronic device, in the field of wireless communication networks.
Background
With the release of 5G license plates in 2019, operators are working on the infrastructure of 5G networks in a tight drum. According to the national strategic indication of 'new capital construction' in China, operators need to accelerate the deployment and coverage of 5G access networks. Compared with 4G, the wireless signal frequency band used by 5G is higher, the signal coverage area is smaller, and the 5G construction operation and maintenance cost is greatly improved. Therefore, the 5G co-construction sharing of multiple operators will become the preferred solution for 5G infrastructure. The 5G co-construction sharing refers to a mode that a plurality of operators jointly build a 5G network, namely, the operators can allow other operator users to perform 5G access in a certain signal coverage area. The 5G co-construction sharing is beneficial to efficiently constructing a 5G network, reduces the network construction and operation and maintenance cost, improves the network benefit and the asset operation efficiency, and quickly forms the 5G service capability.
In the 3GPP 5G standard, a user Plane function (upf) (user Plane function) network element is introduced as a user Plane deployed in a distributed manner, so as to implement separation of a 5G core network control Plane cp (control Plane) and a user Plane up (user Plane). As shown in fig. 1, since the CP of the 5G core network is decoupled from UP, UPF can be flexibly deployed to the network Edge, and support the common deployment with Multi-Access Edge Computing MEC (Multi-Access Edge Computing) to implement local offloading, and all network elements of the 5G-CP include Access and Mobility Management functions AMF (Access & Mobility Management Function) and session Management functions smf (session Management Function), etc., which are centrally deployed at the core network location of each operator, so as to facilitate the unified operation and maintenance Management of the 5G-CP.
The decoupling of the CP and the UP of the 5G core network realizes the high sinking of the forwarding termination of the user data on one hand, and avoids the service end-to-end time delay and the increase of the occupation of the backbone network caused by the user data bypassing the core network; on the other hand, the control signaling of 5G can be uniformly managed, and the reliable and safe communication of the carrier level is realized.
The sinking of the UPF network element causes that the UPF network element also needs to be deployed as a base station at multiple points, and in consideration of the requirement of reducing the construction, operation and maintenance cost of the co-construction and sharing of the 5G network, the UPF network element also needs to be added into the co-construction and sharing category. However, the inventor finds that, at present, operators only implement the co-building sharing of Access networks (R) AN (Radio) Access Network, and the existing 5G Network architecture cannot support the UPF Network element sharing under the control of multiple core networks of multiple operators.

Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The user mainly refers to an operator; when a user deploys a 5G network, the convergence of the UPF network element causes the UPF network element to need multipoint deployment as a base station. In the existing 5G network architecture, the UPF network elements of different users cannot be shared. For example: if the user 1 deploys 1 UPF network element 1 in a certain area, and the user 2 does not deploy the UPF network element in the area; if the user 1 does not need to use the UPF network element in a certain period, and the user 2 needs to use the UPF network element in the certain period, however, the UPF network element 1 is only connected with the core network of the user 1 during deployment, so that the user 2 cannot use the UPF network element 1. Therefore, in the existing 5G network architecture, because the UPF network element is fixedly connected with the core network of a single user, the UPF network element only belongs to the single user; even if the user to which the UPF network element belongs has no requirement, other users cannot use the UPF network element.
Aiming at the problem, the invention provides a user plane function network element sharing method; in the user plane functional network element sharing method, the virtual UPF network element set can be communicatively connected to a core network of at least 2 users, and on the basis of the resource allocation signaling, the virtual UPF network element set can perform resource allocation according to the needs of the users, that is: the virtual UPF network element set can connect the same virtual UPF entity with core networks of different users according to actual conditions. Therefore, the user plane functional network element sharing method of the invention can allow a plurality of users to share the virtual UPF entity in the virtual UPF network element set.
Referring to fig. 2, in an embodiment of the present invention, the method for sharing a user plane functional network element includes:
s21, acquiring the resource use condition of a virtual UPF network element centralized user; the virtual UPF network element set comprises a plurality of virtual UPF entities and can be in communication connection with the core networks of at least 2 users. Wherein the resources of the virtual UPF network element set include computing, storage and network resources. The virtual UPF entity refers to a basic unit for resource allocation in the virtual UPF network element set, and the resources of the virtual UPF network element set comprise the sum of the resources of all the virtual UPF entities. The virtual UPF entity can be a single UPF network element, 2 UPF network elements or a plurality of UPF network elements, and the UPF instance is used as a unit for allocation when resource allocation is carried out.
It should be noted that, the virtual UPF network element set can be communicatively connected with the core networks of at least 2 users, which means that the virtual UPF network element set has the capability of being communicatively connected with the core networks of at least 2 users; in a specific application, the core network communicatively connected to the virtual UPF network element set may be a core network of 1 user, a core of 2 users, or a core network of multiple users.
S22, according to the resource usage of the user, obtaining a resource allocation signaling. Wherein the resource allocation signaling is used to indicate the number of resources allocated to each user. Preferably, the resource allocated to a certain user also comprises a part of redundant resources besides meeting the current requirement of the user for the resource; when the demand of the user for the resources suddenly increases, the existence of the redundant resources enables the resources allocated to the user to still meet the demand of the user.
S23, according to the resource allocation signaling, allocating the resources of the virtual UPF network element set to the user. Specifically, step S23 allocates a corresponding number of resources in the virtual UPF network element set to the user according to the resource allocation signaling. Thereafter, the user uses its core network to control the resources allocated to the user, thereby incorporating the resources allocated to the user into its network.
Preferably, in step S23, the resource of the virtual UPF network element set is allocated in units of the virtual UPF entities. At this time, step S23 converts the number of resources allocated to the user into the corresponding number of virtual UPF entities, and then allocates the corresponding number of virtual UPF entities to the user. Thereafter, the user can establish a communication connection with the virtual UPF entity allocated to the user through its core network, and control the virtual UPF entity allocated to the user through its core network, so as to incorporate the virtual UPF entity allocated to the user into its own network.
As can be seen from the above description, the virtual UPF network element set can be regarded as a set of multiple virtual UPF entities, and each UPF instance in the set can be allocated to different users according to actual needs. For example, referring to fig. 3A and 3B, for the virtual UPF entity 1, when the user 1 has a need, the virtual UPF entity 1 can be added to the network of the user 1 through the communication connection between the virtual UPF network element set and the core network of the user 1; when user 1 has no demand and user 2 has demand, the virtual UPF entity 1 can be added to the network of user 2 through the communication connection between the virtual UPF network element set and the core network of user 2. Therefore, the method for sharing a user plane functional network element according to this embodiment can allow different users to share the same virtual UPF entity, so that it is possible for multiple users to share the resource in the virtual UPF network element set.
In an embodiment of the present invention, the virtual UPF network element set is communicatively connected to core networks of 1 user. At this time, the user plane functional network element sharing method obtains the resource use condition of the user in the virtual UPF network element set, and obtains the corresponding resource allocation signaling according to the resource use condition of the user. The resource allocation signaling is used for indicating the number of resources allocated to the user, and the user plane functional network element sharing method allocates the resources with the corresponding number in the virtual UPF network element set to the user according to the resource allocation signaling.
In an embodiment of the present invention, the virtual UPF network element set is communicatively connected to core networks of at least 2 users. At this time, the user plane functional network element sharing method respectively obtains the resource use condition of each user, and obtains the resource allocation signaling of each user according to the resource use condition; and finally, the user plane function network element sharing method completes the resource allocation of each user according to the resource allocation signaling of each user.
In an embodiment of the present invention, an implementation method for acquiring a resource allocation signaling according to a resource usage condition of the user includes: and generating the resource allocation signaling in real time whenever the resource use condition of the user changes. Specifically, when the resource usage of the user is reduced, generating a corresponding resource allocation signaling in real time to indicate that the number of resources allocated to the user is reduced; and the user plane sharing method reduces the resources allocated to the user in real time according to the resource allocation signaling. When the resource usage of the user is increased, for example, the user starts to use redundant resources, generating a corresponding resource allocation signaling in real time to indicate that the number of resources allocated to the user is increased; and the user plane sharing method increases the resources allocated to the user in real time according to the resource allocation signaling.
As can be seen from the above description, the method for sharing a network element with a user plane function according to the present embodiment can dynamically adjust the number of resources allocated to a user in real time according to the resource usage of the user, so as to implement real-time sharing of the virtual UPF network element centralized resource by the user.
Because the UPF network element is an important forwarding entity of the telecommunication network, dynamically allocating the resources in the virtual UPF network element set in real time may cause interruption of the routing forwarding function, thereby causing system instability. To address this problem, in an embodiment of the present invention, at the beginning of each period, the resource allocation signaling is generated according to the resource usage of the users in the previous equivalent period. Wherein, the period can be configured according to actual requirements, for example: half a day, 1 week, etc.; in the telecommunication network, for any period, the last equivalent period refers to a period of time having the same or similar traffic characteristics as the period, and the duration of the last equivalent period is the same as the duration of the period. For example, if 1 day is taken as the cycle, the previous equivalent cycle of a certain weekday is the previous weekday of the weekday, the previous equivalent cycle of a certain weekend is the previous weekend, and the previous equivalent cycle of a certain holiday is the same holiday of the last year; for another example, if 1 week is taken as the cycle, the last equivalent cycle of a certain week is the same week in the last year; for example, if a half day is used as the cycle, the previous equivalent cycle of a certain workday day is the day of the previous workday, the previous equivalent cycle of a certain workday night is the night of the previous workday, and so on. It should be noted that, the above mentioned is only an example of the case of the last equivalent cycle when a half day, a day or a week is taken as a cycle, and in a specific application, the length and the time period of the cycle may be configured according to actual requirements, so as to determine the corresponding last equivalent cycle, and the specific configuration manner is not described herein again.
In this embodiment, a specific implementation method for generating the resource allocation signaling according to the resource usage of the user in the previous equivalent period includes: when a new period starts, step S21 obtains the resource usage of the virtual UPF network element centralized users in the same period, and step S22 generates the resource allocation signaling according to the resource usage of the virtual UPF network element centralized users in the same period. Thereafter, step S23 allocates the resources in the virtual UPF network element set according to the resource allocation signaling.
Therefore, the method for sharing a user plane functional network element according to this embodiment dynamically allocates the resources in the virtual UPF network element set only at the beginning of each period, so that system instability caused by the dynamic real-time resource allocation can be avoided.
In addition, for any cycle, the method for sharing a user plane functional network element according to this embodiment generates the resource allocation signaling according to the resource usage of the user in the last equal cycle of the cycle, and the last equal cycle and the cycle have the same or similar traffic characteristics, so the embodiment fully considers the traffic characteristics of the networks in different cycles, and makes the allocation of the virtual UPF network element centralized resource more accurate.
In practical application, when a 5G network includes an MEC system, the 5G MEC needs to perform local offloading for a specific traffic, and when a user plane bearer for edge computation is established for a user, a problem to be solved first is how to select a UPF network element to implement local traffic offloading. In order to shorten the transmission delay and improve the transmission efficiency, an important factor to be considered when selecting the UPF network element is the resource utilization condition of the UPF network element. To achieve this object, in an embodiment of the present invention, after allocating resources of the virtual UPF network element set to users, the method for sharing user plane functional network elements further includes: and sending the resource condition of each virtual UPF entity to a Session Management Function (SMF) of a corresponding user to assist the SMF in completing selection of UPF network elements. Specifically, after the SMF obtains the resource condition sent by the virtual UPF entity, the SMF can obtain the resource condition of each UPF network element connected to the SMF according to the resource condition, thereby implementing selection of the UPF network element. After the SMF obtains the resource condition of each UPF network element connected to it, the selection of the UPF network element may be implemented by using the prior art, which is not described herein again.
When the resources in the virtual UPF network element set are shared, the constructor and the user of the virtual UPF network element set are often different, so that a reasonable charging scheme needs to be designed to ensure the rights and interests of the constructor when the resources in the virtual UPF network element set are shared. To achieve this object, in an embodiment of the present invention, the method for sharing a user plane function network element further includes: and acquiring the cost required to be borne by the user according to the resource use condition of the user. Specifically, the virtual UPF network element set may generate operation and maintenance costs during the operation and maintenance process, and the user plane functional network element sharing method determines an assumed proportion of the user to the operation and maintenance costs according to an actual resource usage of the user.
In an embodiment of the present invention, the virtual UPF network element collection uses a virtualization architecture to maintain and manage images of a plurality of user virtual UPF entities. In addition, the virtual UPF network element set may implement virtual deployment by adopting virtual machine deployment, container deployment or hybrid deployment, and in a specific application, the virtual UPF network element set may be selected from the three deployment manners according to actual conditions such as hardware support conditions and isolation requirements.
Specifically, the virtual machine deployment refers to deploying the UPF network element set in a virtual machine manner. By adopting a virtual machine deployment mode, good encapsulation can be provided for the virtual UPF network element set, and good isolation can be provided for the virtual UPF entity in the virtual UPF network element set; meanwhile, the virtual UPF network element set adopting the virtual machine deployment mode is independent of hardware, and seamless migration can be realized between the same hardware abstraction layers, so that maintenance and upgrading are simple. The container deployment mode is that the virtual UPF network element set is deployed as a container, and compared with a virtual machine deployment mode, the container deployment is lighter, so that system resources can be utilized more efficiently, and the system can be started quickly and migrated more easily; however, the container deployment approach provides less isolation than the virtual machine deployment approach. The hybrid deployment mode is that a virtual machine deployment mode is adopted for part of resources of the virtual UPF network element set, and a container deployment mode is adopted for part of resources; therefore, the hybrid deployment approach is a compromise between virtual machine deployment and container deployment.
In an embodiment of the present invention, a plurality of virtual UPF entities in the virtual UPF network element set can simultaneously support different node functions, that is: and a plurality of virtual UPF entities in the virtual UPF network element set have the capability of simultaneously supporting different node functions. For example: at a certain moment, the virtual UPF entity 1 in the virtual UPF network element set is used as a PDU (Protocol Data Unit) session anchor point, and meanwhile, the virtual UPF entity 2 in the virtual UPF network element set is used as an uplink classifier.
Specifically, the virtual UPF entity can support one or more of the following functions: as PDU conversation node interconnected with mobile infrastructure and data network, completing encapsulation and decapsulation of UP protocol; a PDU session anchor for intra-RAT (Radio Access Technologies) or inter-RAT mobility; packet routing and forwarding; data packet inspection and UP policy rule execution; lawful interception; providing an UP flow collection interface and a flow use condition report for charging and legal interception; an Uplink Classifier UL CL (Uplink Classifier) for supporting the routing of traffic flows to the data network; a branch point function for supporting a multi-homed PDU session; QoS handling of UP.
In an embodiment of the present invention, a plurality of virtual UPF entities in the virtual UPF network element set simultaneously support a session anchor function, an uplink classifier function, and/or a branch point function.
Specifically, if a PDU session anchor point is needed in the user network, the 5G core network of the user may use one virtual UPF entity in the virtual UPF network element set as the PDU session anchor point through the SMF to process the PDU session service.
If the user network needs UL CL, the 5G core network of the user may configure one or more virtual UPF entities in the virtual UPF network element set as UL CL through SMF; when the PDU session connection is established or after the PDU session is established, the 5G core network of the user can insert the UL CL into the data path of the PDU session through the SMF, so that the UL CL shunts the data traffic to the local network or different data networks according to the traffic filter issued by the SMF. Optionally, after the PDU session is established, the user's 5G core network may delete the UL CL from the data link of the PDU session through the SMF. Optionally, the 5G core network of the user may include one or more UL CLs in the PDU session through the SMF.
If a branch point is needed in the user network, the 5G core network of the user can configure one or more virtual UPF entities in the virtual UPF network element set as the branch point through SMF; when the PDU session connection is established or after the PDU session is established, the 5G core network of the user can insert the branch point into a data path of the PDU session through the SMF; the branch point can support multi-homing of PDU sessions in association with multiple IPV6 prefixes, thereby providing access to the data network through multiple PDU session anchor points. Optionally, the 5G core network of the user may delete the branch point from the data path of the PDU session through the SMF.
For example, referring to fig. 4, the virtual UPF entity 11 in the virtual UPF network element set is connected to the 5G core network of the user 1 as a PDU session anchor point. Meanwhile, the virtual UPF entity 21 in the virtual UPF network element set is connected to the 5G core network of the user 2 as an uplink classifier, and the virtual UPF entity 31 in the virtual UPF network element set is connected to the 5G core network of the user 3 as a branch point.
In an embodiment of the present invention, each of the virtual UPF entities in the virtual UPF network element set can support all relevant 3GPP standard interface definitions. Specifically, each virtual UPF entity in the set of virtual UPF network elements can interface with an access network over an N3 interface, can interface with an SMF of a user 5G core network over an N4 interface, and/or can interface with a local data network over an N6 interface. Furthermore, when the virtual UPF entity performs local breakout as a UL CL or a branch point, each virtual UPF entity as a UL CL or a branch point can interface with other UPF anchor points through an N9 interface.
Referring to fig. 5, in an embodiment of the present invention, the user is an operator, and the method for sharing the user plane functional network element includes:
s51, obtaining the resource demand of each operator, and performing initial allocation to the resource in the virtual UPF network element set according to a preset resource allocation strategy.
S52, in the running process of the virtual UPF network element set, a usage record module is used for counting the resource usage of each virtual UPF entity; the resource usage of each virtual UPF entity can be obtained from the resource usage report provided by each virtual UPF entity.
S53, when each period starts, submitting the resource use condition of the previous equal period to a resource allocation module, and generating a resource allocation signaling by using the resource allocation module according to a preset resource allocation strategy; the resource allocation signaling is used for indicating how to allocate the computation, storage and network resources in the virtual UPF network element set to each operator.
S54, sending the resource allocation signaling to a virtual machine management module or a container management module, and reallocating the resources of the virtual UPF network element set to each operator by using the virtual machine management module or the container management module.
And S55, after the resource reallocation is completed, each virtual UPF entity reports the resource condition of itself to the SMF network element to which it belongs, so as to assist the SMF in UPF selection.
Optionally, after step S52, the method for sharing a user plane functional network element further includes: and the use recording module sends the resource use condition of each virtual UPF entity to a charging module so that the charging module can obtain the operation and maintenance cost required to be borne by each operator according to a preset cost sharing rule.
Based on the above description of the user plane function network element sharing method, the present invention also provides a computer readable storage medium having a computer program stored thereon. The computer program, when executed by a processor, implements the user plane functional network element sharing method described in the present invention.
Based on the above description of the user plane function network element sharing method, the invention also provides an electronic device; the electronic device includes: a memory storing a computer program; and the processor is in communication connection with the memory and executes the user plane function network element sharing method when calling the computer program.
The protection scope of the method for sharing user plane functional network elements according to the present invention is not limited to the execution sequence of the steps listed in this embodiment, and all the schemes of adding, subtracting, and replacing steps in the prior art according to the principles of the present invention are included in the protection scope of the present invention.
The invention provides a sharing method of a user plane functional network element, aiming at the problem that the current 5G architecture does not support the co-construction and sharing of a UPF network element by multiple operators.
