Detailed Description
The following detailed description of specific embodiments of the present application refers to the accompanying drawings. It should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application.
In the 5G network, when the UE registers with the network, the requested network slice selection assistance information (Network Slice Selection Assistance Information, nsai) may be provided in the registration request, and the network will determine whether the nsai requested by the UE can be allowed to be used according to the service subscription condition of the UE, the current access area of the UE, and so on. The network returns an allowed NSSAI to the UE according to the judging result, wherein the allowed NSSAI comprises a plurality of pieces of allowed single network slice selection auxiliary information (Single Network Slice Selection Assistance Information, S-NSSAI).
In an application scenario that the UE accesses the far-end network through the near-end network, the near-end network and the far-end network allocate allowable NSSAI for the terminal respectively, and there is no mapping relation between network slices of the near-end network and the far-end network. When the data stream of the terminal flows through the near-end network and the far-end network, if there is a large difference in service quality capability between the network slice used in the near-end network and the network slice used in the far-end network, resource waste is caused to the network slice with higher service quality capability. Moreover, the user pays a fee for the wasted resources.
In view of this, the present application provides a session method, a terminal, and a session functional entity, where whether the quality of service capability between network slices of different networks is matched is determined by the quality of service parameters of the network slices, so that when the terminal is in session with a target application, the quality of service capability of the network slice in the first network and the network slice in the second network used are matched, which avoids wasting network resources with a higher side of the quality of service capability, and improves the utilization ratio of the resources.
Fig. 1 is a schematic diagram of a network structure according to an embodiment of the present application. As shown in fig. 1, a terminal 100 accesses a near-end network 110, and the near-end network 110 accesses a far-end network 130 through a data network 120.
Specifically, the terminal 100 is connected to a radio access network (Radio Access Network, RAN) 111, a first access and mobility management function (Access and Mobility Management Function, AMF) entity 112, so as to access the near-end network 110, and the first access and mobility management function entity 112 is responsible for management functions of registration, connection, reachability, mobility, etc. of the terminal 100 in the near-end network 110, and the first session management function (Session Management Function, SMF) entity 113 manages sessions of the terminal 100 in the near-end network 110. Also, a user plane function (User plane function, UPF) entity 114 connects the radio access Network 111 to a Data Network (DN) 120, and the Data Network 120 is connected to a Non-3GPP interworking function (Non-3GPP InterWorking Function,N3IWF) entity 131 of the remote Network 130, thereby allowing the terminal 100 to access the remote Network 130 through the near-end Network 110. In the remote network 130, the non-3GPP interoperable functional entity 131 is connected to a second access and mobility management functional entity 132, the second access and mobility management functional entity 132 is connected to a second session management functional entity 133, and the second access and mobility management functional entity 132 is responsible for management functions of registration, connection, reachability, mobility, etc. of the terminal 100 in the remote network 130, and the second session management functional entity 133 manages sessions of the terminal 100 in the remote network 130.
It should be noted that, when the terminal 100 establishes a session with another device or server through the near-end network 110 and the far-end network 130, a data stream between the terminal 100 and the other device or server flows through the near-end network 110 and the far-end network 130, and the near-end network 110 and the far-end network 130 provide quality of service for the data stream. In some implementations, the near-end network 110 and the far-end network 130 each allocate a network slice for the terminal 100, with the data stream carried by the allocated network slice. In practical applications, there is no mapping relationship between the network slice of the near-end network 110 and the network slice of the far-end network 130, so if the network slice of the near-end network 110 and the network slice of the far-end network 130 have a large difference in quality of service capability, resources of the network slice having a high quality of service capability are wasted.
The first aspect of the present application provides a session method. Fig. 2 is a flowchart of a session method provided in an embodiment of the present application, where the session method is applicable to a terminal. As shown in fig. 2, the session method includes the steps of:
in step S201, a quality of service parameter of the first target network slice is obtained.
Wherein the first target network slice is a network slice in the first network that serves the target application. The target application is an application located on or connected to the first network. The quality of service (Quality of Service, qoS) parameter is a parameter regarding the quality of service of a network slice. Quality of service parameters include, but are not limited to, bandwidth, jitter, and packet loss rate. In practical application, the type of the quality of service parameter to be acquired by the terminal is determined according to the user demand or preset configuration.
In some embodiments, the terminal sends a registration request to a first network, determines a first allowed network slice, wherein the first allowed network slice is a network slice in which the first network opens a right of use for the current terminal; selecting a first target network slice matched with the target application from the first allowable network slices according to the terminal policy configuration information; a quality of service parameter of a first target network slice is obtained from a first network. The terminal policy configuration information includes configuration information local to the terminal and/or UE routing policies (UE Route Selection Policy, urs) that may reflect the network slice usage policies of the UE for each application. The urs may be stored in a local storage space of the terminal or in a policy control function (Policy Control Function, PCF) entity of the first network. When the urs are stored in the PCF, the UE needs to acquire the urs by sending a query request to the PCF, etc.
For example, when the terminal registers with the first network through the N3IWF, the access and mobility management function in the first network returns to the terminal an allowed nsai, which is the first allowed network slice. Wherein, the NSSAI is allowed to comprise n S-NSSAI, which are S-NSSAI#1, S-NSSAI#2, … …, S-NSSAI#n, n is the number of S-NSSAI, and n is an integer greater than or equal to 1. Further, assuming that the target application is a video service class application and the terminal policy configuration information presets that the video service class application uses S-nsai#1, a first target network slice selected from the allowable nsais and matched with the target application is S-nsai#1. The terminal obtains the service quality parameter of S-NSSAI#1 from the first network.
Step S202, determining a second target network slice matched with the first target network slice in the second network according to the service quality parameter of the first target network slice.
The second target network slice is a network slice with the quality of service capability matched with that of the first target network slice. The second network is a network connecting the first network and the current terminal.
In some embodiments, second network subscription information is obtained; determining a second allowed network slice according to the second network subscription information, wherein the second allowed network slice is a network slice of which the second network opens the use authority for the current terminal; acquiring a service quality parameter of a second allowable network slice; calculating the service quality difference value of the first target network slice and the second allowable network slice according to the service quality parameter of the first target network slice and the service quality parameter of the second allowable network slice; and selecting the second target network slice from the second allowable network slice according to the service quality difference value between the first target network slice and the second allowable network slice and the preset value range. Wherein the second network subscription information includes information of a network slice subscribed by the terminal in the second network. In some implementations, the second network subscription information may be obtained from a unified data management function (Unified Data Management, UDM) of the second network.
The calculating the qos difference according to the qos parameters mainly includes two cases, in the first case, the qos parameters to be compared between the first target network slice and the second allowable network slice are only one type, and in the second case, the qos parameters to be compared between the first target network slice and the second allowable network slice are two or more types.
For example, the qos parameters to be compared have only a bandwidth, and if the bandwidth of the first target network slice is D1 and the bandwidth of the second allowed network slice is D2, Δd1=d1-D2, Δd1 represents the bandwidth difference between the first target network slice and the second allowed network slice (in the present case, the qos difference is equal to the bandwidth difference).
For another example, the service quality parameters to be compared include a bandwidth and a packet loss rate, assuming that the bandwidth of the first target network slice is D3, the packet loss rate is P1, the bandwidth of the second allowed network slice is D4, the packet loss rate is P2, Δd2=d3-D4, Δp1=p1-P2, Δf=w1×Δd2+w2×Δp1, where Δd2 represents a bandwidth difference value between the first target network slice and the second allowed network slice, Δp1 represents a packet loss difference value between the first target network slice and the second allowed network slice, Δf represents a service quality difference value between the first target network slice and the second allowed network slice, w1 is a weight coefficient corresponding to the bandwidth, w2 is a weight coefficient corresponding to the packet loss rate, and a sum of w1 and w2 is equal to 1.
It should be noted that the above method for calculating the qos difference is merely illustrative, and the present application is not limited thereto.
It should be further noted that the preset value range may be set according to any one or more of experience, statistics, and actual requirements, which is not limited in this application. For example, the preset value range includes zero, in which case the second allowable network slice is determined to be the second target network slice when the quality of service capabilities of the first target network slice and the second allowable network slice are the same. As another example, considering that there is a certain tunnel encapsulation overhead in the internet security protocol (Internet Protocol Security, IPsec) in the first network, for the same data flow, the resources (e.g., bandwidth) required in the first network are greater than those required in the second network, and thus, the preset value range may be determined based on the tunnel encapsulation overhead, so that the second target network slice satisfying the tunnel encapsulation overhead is selected from the second network according to the preset value range. It is to be understood that the terminal may also directly use the sum of the quality of service parameter and the tunnel encapsulation overhead of the first target network slice as the quality of service reference for selecting the second target network slice from the second network, which is not limited in this application.
Step S203, establishing a session connection between the current terminal and the target application based on the first target network slice and the second target network slice.
In some embodiments, the terminal initiates a data connection request to the target application, and the first network responds to the request by establishing an IPsec based security association (Security Association, SA), i.e. a security association for carrying the data flow of the target application and the current terminal in the first network. The terminal maps a protocol data unit (Protocol Data Unit, PDU) session carrying a target security association in the first network to resources of the first target network slice; mapping the protocol data unit session carrying the current terminal and the target application in the second network to the resource of the second target network slice; and establishing session connection between the current terminal and the target application based on the resources of the first target network slice and the resources of the second target network slice.
In other words, the session connection procedure described above is actually a session modification procedure, i.e. a session is modified to a matching network slice by modifying session parameters, etc., so as to establish a session connection meeting the quality of service requirements.
In this embodiment, a quality of service parameter of a first target network slice is obtained, a second target network slice in the second network, which is matched with the first target network slice, is determined according to the quality of service parameter of the first target network slice, and session connection between a current terminal and the target application is established based on the first target network slice and the second target network slice. According to the method, whether the service quality capacities of the network slices of different networks are matched or not is determined through the service quality parameters of the network slices, so that the service quality capacities of the network slices in the first network and the network slices in the second network are matched when the terminal is in conversation with a target application, waste of network resources on the side with higher service quality capacities is avoided, and the utilization rate of the resources is improved.
Fig. 3 is a flowchart of a session method according to another embodiment of the present application, where the session method is applicable to a terminal. As shown in fig. 3, the session method includes the steps of:
step S301, obtain a quality of service parameter of the first target network slice.
Step S302, determining a second target network slice matched with the first target network slice in the second network according to the service quality parameter of the first target network slice.
Steps S301 to S302 in this embodiment are the same as steps S201 to S202 in the previous embodiment of the present application, and are not described here again.
Step S303, updating the corresponding relation of the historical network slice according to the first target network slice and the second target network slice matched with the first target network slice.
The historical network slice corresponding relation comprises a mapping relation between a first target network slice and a second target network slice.
It should be noted that, after the corresponding relationship of the historical network slice is established, if the terminal establishes the session connection with the target application again, the second target network slice may be determined according to the corresponding relationship of the historical network slice, so as to establish the session connection meeting the requirement of the service quality. In other words, when the first target network slice or the second target network slice is determined, the second target network slice or the first target network slice corresponding to the first target network slice can be determined according to the historical network slice correspondence relationship.
For example, after the terminal determines the first target network slice, a second target network slice matching the first target network slice is determined according to the historical network slice correspondence.
Step S304, establishing a session connection between the current terminal and the target application based on the first target network slice and the second target network slice.
Step S304 in this embodiment is the same as step S203 in the previous embodiment of the present application, and will not be described here again.
In this embodiment, according to the first target network slice and the second target network slice matched with the first target network slice, the historical network slice corresponding relationship is updated, so that the historical network slice corresponding relationship can be always kept accurate. In addition, the embodiment provides a method for determining the second target network slice matched with the first target network slice according to the corresponding relation of the historical network slice besides determining the second target network slice according to the service quality parameter of the network slice, so that the flexibility of determining the matched network slice can be improved.
Fig. 4 is a flowchart of a session method according to still another embodiment of the present application, where the session method is applicable to a terminal. As shown in fig. 4, the session method includes the steps of:
In step S401, a quality of service parameter of the first target network slice is obtained.
Step S402, determining a second target network slice matched with the first target network slice in the second network according to the service quality parameter of the first target network slice.
Steps S401 to S402 in this embodiment are the same as steps S201 to S202 in an embodiment of the present application, and are not described here again.
Step S403, in the case that it is determined that there is no second target network slice matching the first target network slice in the second network according to the quality of service parameter of the first target network slice, updating the subscription policy of the current terminal to the second network.
The subscription policy refers to a policy used when a terminal subscribes to a service in a network. For example, if the subscription policy is a low service level, then a network slice with a lower quality of service capability is subscribed from the second network based on the subscription policy; as another example, if the subscription policy is a high service level, then a network slice with a higher quality of service capability is subscribed from the second network based on the subscription policy.
In some embodiments, in the event that it is determined from the quality of service parameters of the first target network slice that there is no second target network slice in the second network that matches the first target network slice, the terminal is instructed to subscribe to a network slice in the second network that has a quality of service capability that is either higher than the first target network slice or lower than the first target network slice, but not close to the quality of service capability of the first target network slice. Thus, the current subscription policy of the terminal to the second network is updated so that the terminal re-subscribes to the network slice in the second network according to the updated subscription policy.
Step S404, ordering the network slice of the second network based on the updated ordering policy, and obtaining a third allowed network slice.
Wherein the third allowed network slice comprises a network slice subscribed by the terminal from the second network according to the updated subscription policy.
In step S405, a second target network slice is selected from the third allowable network slices according to the quality of service parameters of the first target network slice.
The method for selecting the second target network slice from the third allowable network slice according to the quality of service parameter of the first target network slice is the same as the method for selecting the second target network slice from the second allowable network slice, and will not be described herein.
It should be noted that, in some embodiments, after selecting the second target network slice, the terminal may further update the historical network slice correspondence based on the selected second target network slice and the first target network slice.
Step S406, establishing a session connection between the current terminal and the target application based on the first target network slice and the second target network slice.
Step S406 in this embodiment is the same as step S203 in an embodiment of the present application, and will not be described here again.
In this embodiment, when all the network slices ordered by the terminal in the second network do not meet the requirement, the ordering policy is updated, the terminal orders the network slices in the second network according to the updated ordering policy, and selects the second target network slice from the newly ordered network slices, so that when the terminal is in session with the target application, the network slices in the first network and the network slices in the second network are used to match the service quality capability, thereby avoiding waste of network resources on the side with higher service quality capability and improving the utilization rate of resources.
Fig. 5 is a flowchart of a session method according to another embodiment of the present application, where the session method is applicable to a session functional entity. As shown in fig. 5, the session method includes the steps of:
step S501, the quality of service parameter of the first target network slice is sent to the terminal.
Wherein the first target network slice is a network slice in the current network that serves the target application.
In some embodiments, the terminal sends a registration request to a first network, determines a first allowed network slice, wherein the first allowed network slice is a network slice in which the first network opens a right of use for the current terminal; according to the terminal policy configuration information, a first target network slice matched with the target application is selected from the first allowed network slices; the first network transmits the quality of service parameter of the first target network slice to the terminal. The terminal policy configuration information comprises configuration information and/or URSP of the terminal. The urs may be stored locally at the UE or may be obtained by the UE from the PCF of the first network.
Step S502 establishes a session connection between the terminal and the target application based on the first target network slice and the second target network slice.
The second target network slice is a network slice which is determined according to the service quality parameter of the first target network slice and matched with the first target network slice in the second network, and the second network is a network connecting the current network and the terminal.
