Description

Slice management method and device, access network equipment and core network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a slice management method, a slice management device, an access network device, and a core network device.

Background

Network Slicing (Network Slicing) refers to dividing a physical Network of an operator into a plurality of logically independent virtual networks on the same Network infrastructure, each virtual Network has different functional characteristics, and can flexibly cope with different demands and services, and the virtual networks are isolated from each other, wherein one virtual Network cannot be influenced by the occurrence of faults.

And the network slice provides end-to-end network level service, provides differentiated service for different user groups, and is specially combined into a network by end-to-end network elements to support the characteristics of service isolation and the like. Meanwhile, differentiated services can be further provided for different users and different services in slices through QoS (Quality of Service ) and DNN (Data Network Name, data network name). Even when the overall coincidence is large, the service with guaranteed service quality can be provided for the specific user group.

The current mainstream mode is based on the service scene and carries out slicing, and is divided into three application scenes of eMBB (enhanced Mobile Broadband ) slicing, mMTC (massive Machine Type of Communication, mass machine type communication) slicing and uRLLC (Ultra-reliable and Low Latency Communications, high reliability and low time delay communication) slicing, namely 5G network slicing.

(1) ebb: the name is meant to be directed to high-traffic mobile broadband services, which require that cellular networks provide large bandwidths, and services such as virtual reality AR/augmented reality VR, 4K/8K ultra-high definition video, etc. are of this type.

(2) mctc: for large-scale internet of things service, bandwidth and mobility are not required, but a cellular network is required to support massive access.

(3) uRLLC: this type of traffic requires that the cellular network provide ultra-high reliability ultra-low latency communications, such as traffic such as unmanned traffic (500 ms for 3G response, 50ms for 4G, 0.5ms for 5G).

The slice function resources are divided into independent slices and shared slices according to whether the slice function resources can be shared by other slice resources.

(1) Independent slicing refers to slicing with independent functions, after network resources are sliced, specified user object groups or business scenes can obtain complete and independent end-to-end network resources and business services on a network side, resources among different slices are logically independent, and slicing resources can be called and provide services only in the corresponding slices.

(2) The shared slice means that slice resources can still be shared, scheduled and used by other different independent slices, so as to provide partial sharable business functions and services and improve the utilization rate of resources. The functionality provided by the shared slice may be end-to-end or may provide part of the sharing functionality.

At present, slicing is mainly based on service types and service scenes, after a terminal is accessed, the terminal is accessed to provide end-to-end network level service when in service bearing, differentiated service is provided for different user groups, and the end-to-end network elements are specially combined into a network to support the characteristics of service isolation and the like. Meanwhile, differentiated services can be further provided for different users and different services in the slice through QoS and DNN. Even when the overall load is large, the service with guaranteed service quality can be provided for a specific user group.

1) QoS: providing user-level or business-level services, providing differentiated services for different individual users, or providing differentiated services for different businesses of the same user. Resources are essentially contended according to relative priorities, and when the overall load is large, the service quality of even high QoS users cannot be guaranteed.

2) DNN: providing network element (e.g., UPF (User plane Function, user plane function) network element) level services to distinguish access to different data networks; UPF independent deployment and selection is supported, not end-to-end nor user-level QoS control. Essentially, session splitting is converged to different SMFs (Session Management Function, session management functions)/UPFs according to DNNs, which do not meet end-to-end isolation requirements, and do not support group resource allocation.

In the practical application process, the existing slice management mode cannot perform specific slice management for a specific wireless area.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The slice management method provided by the embodiment of the invention can mainly realize slice management of the following 4 scenes:

1) Only one specific slice exists in the specific area, and a terminal entering the specific area can only access the specific slice;

2) Only one specific slice exists in the specific area, a specific terminal entering the specific area can only access the specific slice, and other non-specific terminals cannot access the slice of the specific area and can only carry out voice communication;

3) Specifically, when a plurality of slices are selectable (comprising a specific slice) in the area, the terminal accesses a specific slice preferentially, and when the terminal adjusts business service, the terminal changes to other slices;

4) The specific area has a plurality of slice options (including a specific slice), some specific terminals can access the specific slice of the specific area, and other terminals can only access other slices.

As shown in fig. 1, an embodiment of the present invention provides a slice management method, which is applied to a first core network device, and includes:

step 11, receiving a second uplink transmission request message sent by a first access network device after receiving a first uplink transmission request message sent by a terminal, wherein the second uplink transmission request message carries first identity identification information of the first access network device;

and step 12, in the case that the first identity identification information indicates that the first access network equipment is located in a specific area, indicating that the terminal accesses a specific slice of the specific area.

As shown in fig. 2, in the embodiment of the present invention, after a terminal enters a specific area, a first uplink transmission request message is sent to a first access network device, and after the first access network device receives the first uplink transmission request message, a second uplink transmission request message is sent to a first core network device, where the second uplink transmission request message carries first identity identification information of the first access network device. The first identity information is used to indicate whether the first access network device is a specific network. For example, the first identity information is 0, which indicates that the first access network device is a normal network; the first identity information is 1, indicating that the first access network device is a specific network (corresponding to the first access network device being located in a specific area).

The first core network device adds an identity analysis function, and when the analysis is 0, the first core network device processes according to a general slice establishment mode (not described in detail herein); when the analysis is 1, the first core network equipment establishes a specific slice of the specific area which is originally appointed; and instructs the terminal to access the particular slice.

In the embodiment of the present invention, the first access network device adds the first identity identification information to the second uplink transmission request message, where the addition location may be at the end of the code stream; after receiving the second uplink transmission request message, the first core network device analyzes the last bit (the first identity information), and after analysis, establishes a slice according to the analysis content of the first identity information.

As an alternative embodiment, the method further comprises:

acquiring second identity information of the terminal;

accordingly, step 12 includes:

Further, the method further comprises:

In other words, a specific terminal can access a specific slice of a specific area in the specific area, and other terminals (also referred to as non-specific terminals) cannot access the specific slice in the specific area (if there are other slices in the area, the other terminals can access the other slices), and the other terminals only support voice services in the specific area.

The second identification information of the terminal may be an identification number of the SIM card (for example, a mobile phone number of the terminal), or may be an EMSI identification number of the terminal (i.e., a model number of the terminal). The EMSI identification numbers of the same terminal are the same, and the terminal can be monitored aiming at the model.

For example, the terminal reports the mobile phone number, and identity verification is performed in the first core network device, if the first core network device records the identity (the first core network device is an authorized identity, if the first core network device does not record the identity), the terminal can access a specific slice of the specific area (and a PDU session can be established after accessing the specific slice); otherwise, the terminal can not access the specific slice of the specific area, can not establish PDU session, and only supports voice service.

For another example, the EMSI verification is performed in the first core network device through the EMSI information reported by the terminal, and if the first core network device is authorized, the terminal can access a specific slice of the specific area (and after accessing the specific slice, a PDU session can be established); otherwise, the terminal can not access the specific slice of the specific area, can not establish PDU session, and only supports voice service.

As another alternative embodiment, in case the specific region contains one of the specific slices and at least one other slice, the method further comprises:

And under the condition that the specific area comprises one specific slice and at least one other slice, the first core network equipment preferentially selects the specific slice by default when the slice is selected, takes the specific slice corresponding to the specific area as the first priority, and only when the service triggered by the terminal is not matched with the specific slice, instructs the terminal to switch to the other slices through switching signaling.

In summary, in the embodiment of the invention, the terminal or the specific terminal is in the specific area, and the core network equipment can establish the specific slice through the identity of the access network equipment and the identity of the terminal, so that the terminal can access the specific slice, thereby realizing service assurance and management on the specific scene, the specific area, the specific service and the specific terminal.

As shown in fig. 3, an embodiment of the present invention further provides a slice management method, which is applied to a second core network device, and includes:

step 31, a first switching request message sent by a second access network device to which the terminal is currently connected is received, wherein the first switching request message carries information of a first PDU session established by the terminal and the second access network device, third identity information of the second access network device and fourth identity information of a third access network device to be switched by the terminal; or receiving a second switching request message sent by third access network equipment to be switched by the terminal, wherein the second switching request message carries information of a first PDU session established by the terminal and the second access network equipment and third identity information of the second access network equipment;

step 32, according to the first switching request message or the second switching request message, a switching confirmation message is sent to a third access network device; the switching confirmation message is used for notifying the third access network equipment of the information of the second PDU session which needs to be updated after the terminal is switched to the specific slice of the specific area where the third access network equipment is located.

The embodiment of the invention is used for describing how to establish a specific slice and initiate a service after a terminal moves from a non-specific area to a specific area.

As an alternative embodiment, the second PDU session is a PDU session of a specific slice of the specific area.

It should be noted that, the third identity information of the second access network device and the fourth identity information of the third access network device to be switched by the terminal are respectively used to indicate whether the corresponding access network device is a specific network (where, the network of the specific area is called a specific network). For example, the identity information is 0, which indicates that the corresponding access network device is a common network; the identity information is 1, and the corresponding access network equipment is a specific network.

Optionally, after the terminal establishes the PDU session in the non-specific area, the terminal may switch to the specific area based on the Xn port or switch to the specific area based on the Ng port in the service process.

If the terminal is switched to the specific area based on the Xn port, a third access network device (namely a target cell) to be switched to the terminal sends a second switching request message to a second core network device, wherein the second switching request message carries information of a first PDU session established by the terminal and the second access network device and third identity information of the second access network device.

For example, based on an Xn port, the second access network device sends a handover request to the third access network device, where the handover request carries information of the first PDU session and third identification information of the second access network device; the third access network device compares the third identity information of the second access network device with the fourth identity information of the third access network device, and discovers that the second access network device belongs to a non-specific network; the third access network device sends a second switching request message to the second core network device, after the second core network device analyzes the second switching request message, the second core network device sends a switching confirmation message to the third core network device, the switching confirmation message carries the information of the second PDU session, after the switching of the third core network device is completed, the PDU session needs to be updated, namely the first PDU session carried by the second access network device is released, and the second PDU session is established.

If the terminal is switched to a specific area based on an Ng port, a second access network device (i.e. a source cell) currently accessed by the terminal sends a first switching request message to a second core network device, wherein the first switching request message carries information of a first PDU session established by the terminal and the second access network device, third identity information of the second access network device and fourth identity information of a third access network device to be switched by the terminal.

For example, the second access network device sends a first handover request message to the second core network device based on the Ng port; after the second core network device analyzes the third identity information of the second access network device, it finds that the second access network device belongs to a non-specific network, and sends a handover confirmation message to the third core network device, where the handover confirmation message carries information of the second PDU session (in this case, the handover confirmation message also carries information of the first PDU session); and after the third access network equipment receives the switching confirmation message, the first PDU session is released, and a second PDU session is established.

Optionally, the third access network device informs the second core network device that the processing of the second PDU session has been completed through the first signaling. Further optionally, the second core network device further needs to notify the second access network device of the information of the second PDU session through the second signaling.

As an alternative embodiment, prior to step 32, the method further comprises:

acquiring fourth identity information of the terminal;

Further, the method further comprises:

It should be noted that, if the second access network device and the third access network device are in the same core network, identity verification of the fourth identity information of the terminal (i.e. judging whether the fourth identity information is an authorized identity) may be completed inside the core network; if the second access network device and the third access network device are not in the same core network, the identity verification of the fourth identity information of the terminal needs to be completed through interactive verification between the core network devices.

Further, when the second service of the terminal needs to be started, a specific slice of a second PDU session of the specific area is established; or, transmitting radio resource control RRC reconfiguration signaling to the terminal, where the RRC reconfiguration information is used to instruct the terminal to update the PDU session between the terminal and the third access network device, and before the method further includes:

In other words, after the terminal is switched from the non-specific area to the specific area, to ensure service continuity, the slice of the first PDU session established by the second access network device is preferentially used for service, and after the service is finished, the first PDU session is released; and re-establishing the slice of the second PDU session or issuing PDU session update through RRC reconfiguration signaling when restarting the service.

Or alternatively, the process may be performed,

after the terminal is switched from the non-specific area to the specific area, to ensure service continuity, the slice of the first PDU session established by the second access network device is preferentially used for service, and after the service is finished, the first PDU session is released; when the service is started again, the identity information of the terminal is judged, and the terminal passing through the verification can reestablish the slice (namely the specific slice) of the second PDU session in the specific area or send PDU session update through RRC reconfiguration signaling. And the other terminals with the identity which is not checked pass the service selection, and the slice types of other PDU sessions are established according to the service selection.

In summary, after the terminal moves from the non-specific area to the specific area, the core network device can establish the specific slice through the identity of the access network device and the identity of the terminal, and the terminal can access the specific slice, so that service assurance and management on specific scenes, specific areas, specific services and specific terminals are realized.

As shown in fig. 4, the embodiment of the present invention further provides a slice management method, which is applied to a second access network device, and includes:

step 41, a first switching request message is sent to a second core network device, wherein the first switching request message carries information of a first PDU session established by a terminal and the second access network device, third identity information of the second access network device and fourth identity information of a third access network device to be switched by the terminal;

Optionally, the third access network device informs the second core network device that the processing of the second PDU session has been completed through the first signaling.

Further optionally, the second core network device further needs to notify the second access network device of the information of the second PDU session through the second signaling. I.e. the method further comprises:
