Technical Field
The present application relates to the field of communications, and in particular, to a method and an apparatus for selecting a network slice.
Background
There is at least one network slice in the access network device, each network slice capable of serving a particular type of communication traffic. In a scenario where the core network device and the access network device belong to the same operator, the access network device can select a network slice corresponding to the network slice identifier to provide a service according to the network slice identifier sent by the core network device of the same operator.
However, in a shared network, different operators may use the same access network device (which may be referred to as a shared device). Since different operators have their own core network devices, there may be a case where the core network devices are different from the operator to which the shared device belongs. In this way, when a core network device (which may be referred to as a first core network device) different from an operator to which the shared device belongs sends a network slice identifier to the shared device, since the network slice identifier does not exist in the shared device, or a network slice corresponding to the network slice identifier in the shared device is different from a network slice requested by the first core network device, the shared device cannot select a correct network slice.

In one possible design, the preset condition is that the correlation coefficient is maximum, the access network device includes N network slices, and N is a positive integer.

In order to facilitate understanding of the technical solution of the present application, before a detailed description is given of a method for referencing a code package in an embodiment of the present application, an implementation environment and an application scenario in the embodiment of the present application are described.
Referring to fig. 1, the method for selecting a network slice according to the embodiment of the present application may be applied to an implementation environment formed by a core network device, a bearer network device, a sharing device, and a terminal. As shown in fig. 1, the implementation environment may include a core network device a, a bearer network device a, a core network device B, a bearer network device B, a sharing device, a terminal a, and a terminal B. The core network device A, the carrying network device A and the sharing device belong to an operator A, and the core network device B and the carrying network device B belong to an operator B; operator a and operator B may both use shared equipment; terminal a is a user of operator a and terminal B is a user of operator B.
The functions of the core network device are mainly to establish a connection for a user (e.g. mobility management, call management, etc.), to manage user data (e.g. user's communication record, user's description, security management of mobile services, etc.), and to complete a bearer connection for a service (e.g. connection to an external circuit data network and a packet data network, etc.), as an interface provided by the bearer network to an external network.
Bearer network equipment is a network located between access network equipment and switches for carrying various voice and data traffic, usually with optical fiber as the transmission medium.
The terminal can be: user Equipment (UE), access terminal, terminal unit, terminal station, mobile station, remote terminal, mobile device, wireless communication device, vehicular user equipment, terminal agent, or terminal device, etc. Optionally, the terminal may be various handheld devices, vehicle-mounted devices, wearable devices, and computers with communication functions, which is not limited in this embodiment of the present application. For example, the handheld device may be a smartphone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, and a laptop computer.
In the embodiment of the application, when a terminal A sends a service data request to a core network device A, the core network device A sends a network slice identifier to a sharing device through a bearer network device A according to the service data request, and the sharing device selects a corresponding network slice to provide a service according to the network slice identifier; when a terminal B sends a service data request to a core network device B, the core network device B sends network slice information to a bearing network device A through the bearing network device B according to the service data request, the bearing network device A sends the network slice information to a sharing device, and the sharing device selects a corresponding network slice to provide service according to a network slice identifier.
The technical scheme provided by the embodiment of the application can be applied to the communication system. The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
As shown in fig. 2, a method for selecting a network slice provided in an embodiment of the present application includes the following steps:
s101, the selection device receives the information of the first network slice sent by the first core network equipment.
The information of the network slice is template configuration information of the network slice.
In a possible implementation manner, a terminal sends a service request to a first core network device; and the first core network equipment matches the network slice meeting the service characteristics in a preset network slice database according to the service characteristics of the service requested by the terminal. The first core network sends the network slice to the selection device, and the selection device receives the network slice.
It should be noted that the network slice database is configured by the operator in advance. Therefore, when the user terminal of the same operator sends a service request to the first core network device, the core network device can certainly find out the network slice satisfying the service characteristics.
Illustratively, table one shows the correspondence between the traffic and the network slice in the network slice database. The service A corresponds to the network slice A, the service B corresponds to the network slice B, and the service C corresponds to the network slice C. When the terminal requests the service A to the first core network equipment, the first core network equipment sends the network slice template A to the selection device.

S102, the selection device determines a second network slice according to the information of the first network slice and the information of all the network slices in the access network equipment.
And the second network slice is a network slice of which the correlation with the first network slice in all the network slices meets a preset condition.
In a possible implementation manner, the selection device inputs information of each network slice and information of a first network slice in the access network device into a preset formula respectively to obtain a plurality of correlation coefficients. The selection device determines a second network slice according to the plurality of correlation coefficients and a preset condition. For a specific process of determining the second network slice, reference may be made to S201 to S203, which is not described herein again.
In the embodiment of the present application, the preset condition may be that the correlation coefficient is maximum, or that the correlation coefficient is greater than a threshold. The embodiment of the present application does not limit this.
It can be understood that, if the correlation between the second network slice and the first network slice satisfies the preset condition, it indicates that the correlation between the second network slice and the first network slice is strong. Therefore, when the first network slice cannot be correctly selected, the selection device may determine a second network slice, replace the first network slice with the second network slice, and provide a second network slice service.
In this embodiment of the present application, an operator to which the first core network device belongs may be different from an operator to which the access network device belongs, and the operator to which the first core network device belongs may also be the same as the operator to which the access network device belongs, which is not limited in this embodiment of the present application.
It is understood that when the operator to which the first core network device belongs is different from the operator to which the access network device belongs, only one network slice can be determined from the network slices in the access network device based on the information of the network slices and the information of all the network slices in the access network device. When the operator to which the first core network device belongs is the same as the operator to which the access network device belongs, if the access network device does not recognize the identifier of the network slice, a network slice may be determined from the network slices in the access network device according to the information of the network slices and the information of all the network slices in the access network device.
Based on the above technical solution, under the condition that the operator to which the first core network device belongs is different from the operator to which the access network device belongs, even if the first network slice identifier does not exist in the access network device or the access network device cannot identify the identifier of the first network slice, the selection device may select, according to the information of the first network slice and the information of all network slices in the access network device, a second network slice whose correlation with the first network slice satisfies a preset condition from all network slices in the access network device. Therefore, the access network equipment can select the correct network slice and provide the corresponding network slice service, and the user experience is improved.
The following describes a process of determining the second network slice by the selection device according to the information of the first network slice and the information of all the network slices in the access network device. As shown in fig. 3, a method for selecting a network slice provided in an embodiment of the present application includes the following steps:
s201, the selection device calculates the correlation between the information of each network slice in the N network slices and the information of the first network slice to obtain N correlation numbers.
The information of the network slice includes M sets of Quality of Service (QoS) parameters.
It should be noted that the QoS parameters include: 5G quality of service Identifier (5G QoS Identifier, 5QI), Allocation and Retention Priority (ARP), Guaranteed traffic Bit Rate (Guaranteed Flow Bit Rate, GFBR), Maximum traffic Bit Rate (MFBR), Aggregate Maximum Bit Rate (AMBR), Session Aggregate Maximum Bit Rate (Session-Aggregate Maximum Bit Rate, Session-AMBR), Maximum Packet Loss Rate (The Maximum Packet Rate), Resource Type (Resource Type), Priority (Priority level), Packet Delay budget (Packet Delay budget), Packet Error Rate (Packet Error Rate), average window (avg _ length), Maximum Data Burst (Maximum _ length).
Illustratively, table two shows the information for network slice a. The information of the network slice a includes two sets of QoS parameters, i.e., a set of QoS parameters corresponding to 5QI being 1 and a set of QoS parameters corresponding to 5QI being 2.
Watch two
Note that 5QI is a quality of service identifier. Each network slice includes at least one 5QI, each 5QI corresponding to a traffic type. Illustratively, a 5QI of 1 corresponds to a video service type and a 5QI of 2 corresponds to a game service type.
In one possible implementation, the selection means randomly orders the N network slices. The selection device calculates the correlation coefficient of the information of each network slice and the information of the first network slice in turn according to the sequence of the N network slices.
In one possible design, the correlation coefficient of the QOS parameter of each of the N network slices with the QOS parameter of the first network slice is determined according to the following formula:
wherein slicET q For the q network slice in the access network device and the first network slice, X i QOS parameter for the q-th network slice in the access network equipment, Yi is QOS parameter of the first network slice, X i And Y i Is the same QOS parameter in the same group of QOS parameters, and q is a positive integer less than or equal to N.
Illustratively, table three is the QoS parameters of the first network slice in the access network device, and table four is the QoS parameters of the first network slice. Then the correlation coefficient between the first network slice and the first network slice in the access network device is:
watch III
Watch four
Note that, if the 5 QIs in the two network slices are different, that is, there is a certain 5QI in one network slice, and there is no 5QI in the other network slice. The values of a set of QoS parameters corresponding to the 5QI in the network slice without the 5QI are all 0. For example, if there is a set of QoS parameters corresponding to 5QI being 1 in the second network slice, and there is no set of QoS parameters corresponding to 5QI being 1 in the first network slice, the values of the set of QoS parameters corresponding to 5QI being 1 in the first network slice are all 0.
S202, the selection device determines the identification of the target network slice, and the target network slice is the network slice corresponding to the maximum correlation coefficient in the N correlation coefficients.
In a possible implementation manner, the selection device sorts the obtained N correlation numbers according to a preset order to obtain a maximum correlation coefficient, and determines an identifier of a network slice corresponding to the maximum correlation coefficient.
The preset sequence may be sorted from small to large, or sorted from large to small. The embodiments of the present application do not limit this.
And S203, the selection device determines the network slice indicated by the identification of the target network slice as a second network slice.
Based on the above technical solution, the selecting device may select, according to the information of the first network slice and the information of all network slices in the access network device, the second network slice with the largest correlation with the first network slice from among all network slices in the access network device. Therefore, the access network equipment can select the correct network slice and provide the corresponding network slice service, and the user experience is improved.
