Technical Field

The present invention relates to communications technologies, and in particular, to a method and an apparatus for processing network slices.

Background

With the rapid development of wireless communication technology, the fifth Generation (5th Generation, abbreviated as 5G) wireless communication technology has been the hot spot in the industry. In the future, wireless communication services are diversified, and different services have different requirements on network performance, for example, a service with high-speed mobile characteristics has higher requirements on network performance indexes such as switching delay and mobility; machine Type Communication (MTC) has high requirements for the number of service connections, and has no requirements for handover delay and mobility. Therefore, in the 5G communication system, in order to meet the requirements of different services on different network performances, the network needs to have the capability of being formulated as required, and flexible network slicing needs to be realized. The development trend of the 5G communication system is to establish different network slices for different types of services through a virtualization technology, each network slice can be regarded as a complete network, and the network slices corresponding to the different types of services can adopt different network forms, for example, different protocol stack structures are adopted on a data plane or a signaling plane to better match the characteristics of the services.

When different network slices adopt different data or signaling transmission protocols, if a terminal device needs to be switched from one network slice to another network slice, or the terminal device needs to be simultaneously accessed to another network slice, a protocol stack corresponding to an original network slice on the terminal device may not match with a protocol stack corresponding to a switched network slice or a newly accessed network slice, thereby causing a problem that the terminal device fails to switch the network slice.

As shown in fig. 1, the network slices are divided in the data plane, and all network slices share common control plane functions. A network slice consists of a set of one or more network functions and resources capable of running those network functions. Wherein the network functions can provide the required telecommunication services and network capabilities. A network function is a processing unit in a network that has a defined functional behavior and a defined interface. The Network slice includes an evolved Node B (eNB), a Serving Gateway (SGW) and a Packet Data Network Gateway (PGW) connected in sequence. The control plane includes a Mobility Management Entity (MME), a Home Subscriber Server (HSS), a Policy and Charging Rules Function (PCRF), a slice manager, and a Software Defined Protocol Controller (SDPC).

"indicates the connection of the data planes, dotted line"

"denotes the connection of the control plane. The terminal device and the network slice are connected by a data plane and a control plane.

The network manager in the embodiment of the invention comprises a slice manager and an SDPC. The slice manager and the SDPC may be located in the same entity or in different entities, with the two being interfaced. The network manager may be located in an entity in the existing network that logically functionally implements the functionality of the network manager. The slice manager is responsible for generation of network slices, resource allocation, access selection, access authorization and the like. The slice manager completes the generation of the network slices by establishing the connection and the bearing of each network slice. And according to the logic function corresponding to the network slice, completing the mapping of the logic function and the physical resource to realize the resource allocation. And selecting a default network slice for the terminal equipment according to the subscription information of the terminal equipment to realize access selection. When the terminal device needs to switch or simultaneously access the network slice, the terminal device is authorized to realize access authorization when the terminal device can switch to the target network slice or access the network slice. The SDPC is used for carrying out protocol configuration on the network entity function on the network slice according to the service type supported on the network slice and selecting the protocol configuration information corresponding to the network slice which needs to be accessed by the terminal equipment. Different types of traffic may be carried on different network slices. The terminal device may access different network slices to perform different services.

When a first type of traffic is in progress on the terminal device, it may access the network slice 11. The network slice processing method provided by the embodiment of the invention can be applied to the following scenes: when the terminal device needs to perform a second type of service, the performance of the network slice 11 cannot meet the requirement of the second type of service, and the terminal device needs to be switched to the network slice 12; and when the terminal device needs to perform the second type of service while performing the first type of service, the terminal device needs to access the network slice 12 at the same time.

The terminal device in the embodiment of the invention can be a handheld device, a vehicle-mounted device, a wearable device, a computing device, various forms of User Equipment (UE), a Mobile Station (MS), a terminal (terminal) and the like.

Fig. 2 is a signaling interaction diagram of a network slice processing method according to a first embodiment of the present invention. As shown in fig. 2, the network slice processing method provided in the embodiment of the present invention includes the following steps:

s201: the terminal device accesses the source network slice.

Specifically, the terminal device may send an access request to the network manager, the network manager performs access authorization on the terminal device according to the access request, and sends configuration information, and the terminal device performs configuration according to the configuration information to access the source network slice.

The source network slice in the embodiment of the invention is a network slice which is currently accessed by the terminal equipment.

In one implementation, the access request may include only the identity of the terminal device when accessing the source network slice. At this time, the network slice manager acquires a default network slice corresponding to the identifier of the terminal device, performs access authorization on the default network slice to the terminal device, acquires protocol configuration information corresponding to the default network slice, and sends the protocol configuration information to the terminal device. And the terminal equipment is configured according to the protocol configuration information corresponding to the default network slice so as to access the default network slice. It should be noted that the default network slice is a network slice determined by the terminal device when signing a contract and capable of meeting the most basic service requirement of the terminal device.

In another implementation manner, when accessing the source network slice, the access request includes an identifier of the source network slice that needs to be accessed, which is determined by the terminal device according to a service that needs to be performed by the terminal device. Since the terminal device does not access the source network slice at this time, the identifier is referred to as an identifier to be accessed, and the corresponding source network slice is referred to as a network slice to be accessed. At this time, the network slice manager performs to-be-accessed network slice access authorization on the terminal device according to the to-be-accessed identifier, acquires protocol configuration information corresponding to the to-be-accessed network slice, and sends the protocol configuration information to the terminal device, and the terminal device performs configuration according to the protocol configuration information corresponding to the to-be-accessed network slice so as to access the to-be-accessed network slice.

S202: the terminal equipment sends a network slice processing request to the network manager, and the network manager receives the network slice processing request sent by the terminal equipment.

Wherein the network slice processing request includes a target identification. The terminal device has access to the source network slice. The terminal equipment sends a network slice processing request to the network manager, wherein the network slice processing request is used for indicating the network manager to perform target network slice access authorization corresponding to a target identifier on the terminal equipment according to the network slice processing request, and acquiring first protocol configuration information corresponding to the target network slice.

An identification of the type of processing request may be included in the network slicing processing request to indicate what type of network slicing processing request is. In the embodiment of the present invention, the network slice processing request may be a network slice switching request or a network slice accessing request. In the network slice processing method provided by the embodiment of the invention, the terminal device has access to a source network slice to run a service, and the connection between a target network slice and a control plane is established. For example, in the first case: the terminal device has access to a source network slice to operate the voice service, at this time, if the terminal device needs to end the voice service to perform the service of connecting the number of degrees of electricity read by the intelligent ammeter, because the current source network slice is suitable for operating the voice service, the source network slice has the characteristics of small delay, low safety and low reliability, and when the terminal device is connected with the number of degrees of electricity read by the intelligent ammeter, the service has high requirements on safety and reliability, so the terminal device needs to be switched from the current source network slice to a target network slice capable of operating and reading the number of degrees of electricity on the intelligent ammeter. In the second case, the terminal device needs to connect the degree of the reading electricity of the smart meter under the condition of not ending the voice service, and the terminal device needs to be accessed into a target network slice which can meet the degree service requirement of the reading electricity and simultaneously is also accessed into a source network slice which runs the voice service. In the first case, the network slice processing request is a network slice handover request. In the second case, the network slice processing request is a network slice access request. The terminal device and the network manager may agree on a rule in advance so that the network manager recognizes the type of the network slicing processing request.

When the terminal equipment needs to operate a new service and the current source network slice cannot meet the requirement of the new service, the terminal equipment sends a network slice processing request to a network manager. The target network slice is a network slice to be accessed or switched to by the terminal equipment.

The target identification may be an identification of the target network slice. The terminal device can inquire the mapping relation between the self-stored service and the network slice, and determine the target network slice according to the type of the target service to be operated, so as to obtain the identifier of the target network slice. Or the terminal equipment inquires the mapping relation between the service type identifier stored in the terminal equipment and the network slice identifier, and determines the target network slice identifier according to the target service type to be operated.

The target identification may also be an identification of the target traffic type. The terminal device can query the mapping relationship between the target service type stored in the terminal device and the identifier of the target service type, and determine the identifier of the target service type according to the target service type to be operated.

It should be noted that the terminal device may first send a network slice processing request to the eNB in the source network slice. And the eNB in the source network slice sends the network slice processing request to the MME of the control plane. And the MME sends the network slice processing request to the network manager. The network manager receives a network slice processing request sent by the MME.

S203: and the network manager performs target network slice access authorization corresponding to the target identifier on the terminal equipment according to the network slice processing request, and acquires first protocol configuration information corresponding to the target network slice.

In particular, in one implementation, the target identification is an identification of the target network slice. The network manager stores the subscription information of the terminal equipment, and performs target network slice access authorization corresponding to the identifier of the target network slice on the terminal equipment according to the subscription information of the terminal equipment and the identifier of the target network slice.

In another implementation manner, the target identifier is an identifier of the target network slice, and the network slice processing request sent by the terminal device further includes the identifier of the terminal device. For example, the identifier of the terminal device may be an International Mobile Subscriber identity (International Mobile Subscriber identity Number; IMSI) or the like. After receiving the network slicing processing request, the network manager acquires the subscription information corresponding to the identifier of the terminal device from the HSS or the PCRF according to the identifier of the terminal device in the network slicing processing request. And if the network manager determines that the terminal equipment can be accessed into the target network slice according to the subscription information and the identification of the target network slice, performing target network slice access authorization corresponding to the identification of the target network slice on the terminal equipment. The subscription information may be information such as a type, a data transmission rate, a bandwidth, a delay, a packet error rate, and the like of an initiated service subscribed by the terminal device when accessing the network.

In yet another implementation, the target identifier is an identifier of a target service type, and the network slice processing request further includes an identifier of the terminal device. After receiving the network slicing processing request, the network manager acquires the subscription information corresponding to the identifier of the terminal device from the HSS or the PCRF according to the identifier of the terminal device in the network slicing processing request. And if the network manager determines that the terminal equipment can access the target network slice according to the subscription information and the identifier of the target service type, performing target network slice access authorization corresponding to the identifier of the target service type on the terminal equipment.

It should be noted that, when the slice manager and the SDPC in the network manager are located in the same entity, that is, integrated together, the network manager may obtain the first protocol configuration information corresponding to the target network slice from the network manager after performing access authorization on the terminal device. When a slice manager and an SDPC in a network manager are separately arranged at different entities, the slice manager performs access authorization on terminal equipment according to a network slice processing request, then the slice manager sends the network slice processing request to the SDPC, the SDPC determines first protocol configuration information corresponding to a target network slice, and then sends the first protocol configuration information to the slice manager.

When the network manager determines that the terminal device can access the target network slice according to the subscription information and the identifier of the target network slice, the network manager may determine in the following manner: and if the subscription information of the terminal equipment comprises the service corresponding to the target network slice, the network manager determines that the terminal equipment can access the target network slice. Of course, the network manager may also perform the determination in other manners, for example, when the bandwidth of the subscription information may satisfy the service corresponding to the target network slice, the network manager determines that the terminal device can access the target network slice. The present embodiment does not limit this.

When the network manager determines that the terminal device can access the target network slice according to the subscription information and the identifier of the target service type, the network manager may determine in the following manner: and if the subscription information of the terminal equipment comprises the target service type corresponding to the identification of the target service type, the network manager determines that the terminal equipment can be accessed into the target network slice.

The first protocol configuration information may include protocol stack configuration information corresponding to the target network slice that the terminal device needs to adopt.

S204: the network manager sends first protocol configuration information to the terminal equipment, and the terminal equipment receives the first protocol configuration information sent by the network manager.

The network manager sends first protocol configuration information to the terminal equipment, wherein the first protocol configuration information is used for indicating the terminal equipment to carry out protocol configuration according to the first protocol configuration information so as to access the target network slice.

Specifically, the network manager may first send the first protocol configuration information to the MME. And the MME sends the first protocol configuration information to the eNB in the source network slice. And the eNB in the source network slice sends the first protocol configuration information to the terminal equipment. The terminal equipment receives first protocol configuration information sent by the eNB in the source network slice.

S205: and the terminal equipment carries out protocol configuration according to the first protocol configuration information so as to access the target network slice.

Specifically, the terminal device in the embodiment of the present invention is a terminal device having a protocol configuration function.

When the terminal device performs protocol configuration according to the first protocol configuration information, there are two implementation manners:

the first implementation mode comprises the following steps: the terminal equipment only stores one kind of basic protocol configuration information, and after receiving the first protocol configuration information, the terminal equipment performs configuration on the basis of the basic protocol configuration information so as to ensure that the protocol stack of the terminal equipment can be matched with the target network slice.

The second implementation mode comprises the following steps: the terminal equipment stores a plurality of different protocol configuration information, and after receiving the first protocol configuration information, the terminal equipment selects the protocol configuration information which is the same as the first protocol configuration information to complete configuration.

And after the terminal equipment is configured according to the first protocol configuration information, triggering the established connection between the terminal equipment and the target network slice and bearing access to the target network slice through the MME or the network manager.

S302: and the network manager acquires a default network slice corresponding to the identifier of the terminal equipment according to the first network slice access request, and performs default network slice access authorization on the terminal equipment.

Specifically, in this case, since the first network slice access request does not include the identifier of the network slice to be accessed, the network manager may obtain, according to the identifier of the terminal device, the default network slice corresponding to the identifier of the terminal device, and perform default network slice access authorization on the terminal device. In this implementation manner, the network manager may also obtain subscription information of the terminal device from the HSS or the PCRF according to the identifier of the terminal device, and then determine the default network slice of the terminal device according to the subscription information. Or, the network manager stores default network slices corresponding to the identifiers of different terminal devices.

In particular, it may be that the network manager triggers the establishment of bearers and connections between the terminal device and the default network slice. And after acquiring the second protocol configuration information corresponding to the default network slice, the network manager triggers the establishment of the bearer and the connection.

Fig. 4 is a signaling interaction diagram of a network slice processing method according to a third embodiment of the present invention. As shown in fig. 4, the network slice processing method according to the embodiment of the present invention is explained in detail based on the embodiment shown in fig. 3:

in an embodiment of the invention, the source network slice is a default network slice. The default network slice and the target network slice comprise an eNB, an SGW and a PGW, and the control plane comprises: MME, slice manager and SDPC.

S401: and establishing the network slice.

Specifically, S401 may include: s401a default network slice setup and S401b target network slice setup. There is no timing relationship between S401a and S401 b. The default network slice and the target network slice are respectively connected with a slice manager in the control plane.

Different network slices are used to carry different types of traffic, using different control/signaling protocol processing architectures. In this process, resource mapping and protocol configuration on different network slices has been completed.

S402: the terminal equipment sends a first network slice access request to the slice manager, and the slice manager receives the first network slice access request sent by the terminal equipment.

In the embodiment of the present invention, the terminal device may first send the first network slice access request to the eNB of the default network slice. And the eNB of the default network slice sends the first network slice access request to the MME. And the MME sends the first network slice access request to the slice manager.

The first network slice access request comprises the identification of the terminal equipment.

S403: and the slice manager acquires a default network slice corresponding to the identifier of the terminal equipment according to the first network slice access request, and performs default network slice access authorization on the terminal equipment.

The default network slice here is the source network slice.

S404: the slice manager sends a first network slice access request to the SDPC.

S405: the SDPC determines second protocol configuration information according to the first network slice access request.

Specifically, the second protocol configuration information includes protocol stack configuration information corresponding to a default network slice that the terminal device needs to adopt.

The SDPC stores the mapping relation between the identification of the terminal equipment and the default network slice corresponding to the identification of the terminal equipment, and also stores the default network slice and the protocol configuration information corresponding to the default network slice. And the SDPC determines a default network slice corresponding to the SDPC according to the identifier of the terminal equipment in the first network slice access request, and then determines protocol configuration information corresponding to the default network slice according to the default network slice.

S406: the SDPC sends the second protocol configuration information to the slice manager, and the slice manager receives the second protocol configuration information.

S407: and the slice manager sends the second protocol configuration information to the terminal equipment, and the terminal equipment receives the second protocol configuration information.

Specifically, the slice manager may send the second protocol configuration information to the terminal device through the MME and the source network slice.

S408: and the terminal equipment performs protocol configuration according to the second protocol configuration information.

Specifically, similar to S205, the terminal device performs protocol configuration according to the second protocol configuration information, and there are two implementation manners:

the first implementation mode comprises the following steps: the terminal equipment only stores one kind of basic protocol configuration information, and after receiving the second protocol configuration information, the terminal equipment performs configuration on the basis of the basic protocol configuration information so as to ensure that the protocol stack of the terminal equipment can be matched with the default network slice.

The second implementation mode comprises the following steps: the terminal equipment stores a plurality of different protocol configuration information, and after receiving the second protocol configuration information, the terminal equipment selects the protocol configuration information which is the same as the second protocol configuration information to complete the configuration.

S409: and establishing the bearing and connection between the terminal equipment and the source network slice.

Specifically, it may be that the MME triggers establishment of bearers and connections between the terminal device and the source network slice. Or the slice manager triggers the establishment of bearers and connections between the terminal device and the source network slice.

If the MME triggers the establishment, after the MME receives the second protocol configuration information sent by the slice manager, the bearer and the connection are triggered to be established. The MME establishes the load and connection between the terminal equipment and the source network slice by generating load-related identification, QoS and maintenance quantity.

If the slice manager triggers the establishment, the slice manager triggers the establishment of the bearer and the connection after receiving the second protocol configuration information sent by the SDPC. The slice manager establishes bearers and connections between the terminal device and the source network slices by generating bearer-related identities, QoS and maintenance volumes.

Or after S408, the terminal device sends a configuration completion message to the slice manager, and after receiving the configuration completion message, the slice manager triggers establishment of a bearer and a connection between the terminal device and the source network slice.

S410: the terminal equipment sends a network slice processing request to the slice manager, and the slice manager receives the network slice processing request sent by the terminal equipment.

Wherein the network slice processing request includes a target identification. Similar to S202, the target identifier may be an identifier of the target network slice, or may be an identifier of the target traffic type.

When the protocol configuration capability information of the terminal device is included in the network slice processing request, before S411, the method further includes: the slice manager may also determine whether the terminal device supports protocol reconfiguration from the protocol configuration capability information of the terminal device. S411 is performed only when the terminal device supports the protocol reconfiguration.

S412: the slice manager sends a network slice processing request to the SDPC.

S413: the SDPC determines first protocol configuration information from the network slice processing request.

Specifically, the first protocol configuration information may include protocol stack configuration information corresponding to the target network slice, which is required to be adopted by the terminal device.

In one possible implementation manner, when the target identifier in the network slice processing request is the identifier of the target network slice, the SDPC stores a mapping relationship between the identifier of the target network slice and the protocol configuration information corresponding to the identifier. And the SDPC determines protocol configuration information corresponding to the identification according to the identification of the target network slice in the network slice processing request.

In another possible implementation manner, when the target identifier in the network slice processing request is an identifier of a target service type, the SDPC stores a mapping relationship between the identifier of the target service type and an identifier of a target network slice corresponding to the identifier of the target service type, and the identifier of the target network slice and protocol configuration information corresponding to the identifier. And the SDPC determines the identifier of the target network slice corresponding to the identifier of the target service type according to the identifier of the target service type in the network slice processing request, and then determines the protocol configuration information corresponding to the identifier according to the identifier of the target network slice.

S414: the SDPC sends first protocol configuration information to the slice manager, which receives the first protocol configuration information.

S415: the slice manager sends the first protocol configuration information to the terminal equipment, and the terminal equipment receives the first protocol configuration information.

S416: and the terminal equipment performs protocol configuration according to the first protocol configuration information.

Specifically, the first implementation manner: the terminal equipment only stores one kind of basic protocol configuration information, and after receiving the first protocol configuration information, the terminal equipment performs configuration on the basis of the basic protocol configuration information so as to ensure that the protocol stack of the terminal equipment can be matched with the target network slice.

S417: and establishing bearing and connection between the terminal equipment and the target network slice.

The implementation principle is similar to S409, and is not described herein again.

Optionally, when the processing request type corresponding to the identifier of the processing request type is a network slice switching request, then:

s418: and the slice manager removes the load bearing and connection between the terminal equipment and the source network slice.

Optionally, S417 and S418 have a timing relationship, that is, the bearer and the connection between the terminal device and the target network slice are established first, and then the bearer between the terminal device and the source network slice is removed. This ensures that the service on the terminal device is not interrupted.

The difference between the network slicing method provided by the embodiment of the present invention and the network slicing method shown in fig. 3 is that: the slice manager and the SDPC in the network manager are separately arranged, when the first protocol configuration information is determined, if the slice manager performs target network slice access authorization corresponding to a target identifier on the terminal equipment, the slice manager sends a network slice processing request to the SDPC, the SDPC determines the protocol configuration information according to the network slice processing request, and the slice manager receives the protocol configuration information sent by the SDPC and determines the protocol configuration information as the first protocol configuration information. While the slice manager and the SDPC in the network manager in the embodiment of the present invention provided in fig. 2 and 3 are integrated, the first protocol configuration information can be directly obtained according to the network slice processing request.
