Embodiment 1

[0103] Embodiment 1: the selection process of the network control function entity whose terminal type is eMBB

[0104] Step 1. The eMBB terminal initiates the access process, and the UE access message carries the UE terminal type as eMBB or the core network control plane identifier eMBB_ID specified by the network side.

[0105] Step 2. Based on the information carried in the access message, the core network control entity selection function entity selects a network control function entity of the eMBB network for the terminal according to the mapping list configured by the network operator.

[0106] Step 3. The access message is forwarded to the network control functional entity that selects the eMBB.

[0107] Step 4. The eMBB network control function entity sends an authentication and authentication message to the HSS, including confirmation of the user's terminal type, identity and other information.

[0108] Step 5. The eMBB assigns default network slices and IP addresses ...

Embodiment 2

[0110] Embodiment 2: Triggered by the eMBB user side, initiated by the network, and selected for network fragmentation of the Video Call service (not a service provided by a third-party service provider)

[0111] Step 1. The UE initiates an IMS-based Video Call service request, and sends an application layer signaling message based on the default network slice. The request carries UE terminal type information and application service type information, and the information is sent by the P-CSCF of the IMS. intercepted.

[0112] Step 2. P-CSCF sends session-related information to the policy and pricing functional entity, including terminal type eMBB, and QoS parameters required by the service, including specific QoS indicators such as packet loss rate 0.0001, delay 150ms, and GBR 0.5Mbps.

[0113] Step 3, the policy and pricing functional entity requests the HSS to obtain the user's subscription information.

[0114] Step 4. The policy and pricing functional entity formulates QoS...

Embodiment 3

[0119] Embodiment 3: User-triggered, user-initiated user video-on-demand (VoD) service network segment selection (service provided by a third-party service provider)

[0120] Step 1. A user wants to access Netflix's VoD service, and sends a service request message to the AF through the default network slice. The request carries UE terminal type information and application service type information, and the information is received by the AF.

[0121] Step 2. The AF sends service-related information to the policy and pricing functional entity of the core network based on the application information, including information about the terminal type eMBB, the application, and its service provider Netflix.

[0122] Step 3. The policy and pricing functional entity requests the HSS to obtain the user's subscription information, and determines that there is a payment agreement between Netflix and the operator.

[0123] Step 4. Apply the service-related QoS indicators requested by the user...

Abstract

The embodiment of the invention provides a service-based network fragment selection method, device and system. The method comprises the following steps: making a QoS (Quality of Service) strategy rule of a service according to at least one of a service type, a service QoS index, user subscription information and strategy information of a third-party service provider through a strategy and pricing function; receiving the QoS strategy rule which is transmitted by a strategy and pricing control function entity and made for a service requested by a terminal; and selecting a network fragment matched with the QoS strategy rule for the service requested by the terminal according to the QoS strategy rule made for the service requested by the terminal. Through adoption of the service-based network fragment selection method, device and system, the problem that different network fragments cannot be selected for different services in a 5G network in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for service-based network slice selection. Background technique [0002] In the next-generation mobile communication network, it is necessary to support richer network applications, adapt to the business needs of various scenarios, meet the service performance requirements of different users, and support various types of device access. In order to support diversified business needs, reduce the cost of network construction and operation, improve the flexibility of network management and the effectiveness of network resources, and increase their own profitability, operators propose to use a "network network" in the next generation mobile communication network Fragmentation" to support specific types of communication services (such as figure 1 ). Network sharding is a combination of specific network functions and network performance based ...
