Embodiment approach 1

[0078] Figure 8 It is a flow chart of a method for successfully selecting a suitable network slice for service when UE actively performs customized services and carries service type information according to an optional embodiment of the present invention, as shown in Figure 8 As shown, the steps of the method include:

[0079] Step S802: When the UE is ready to actively perform services, perform access on the corresponding random access resource according to the service type;

[0080] Step S804: The network side receives the UE's random access request, and identifies the service type according to the random access resource;

[0081] Step S806: the network side carries the slice information list supported under this service type to the UE in the random access response message;

[0082] Step S808: The UE selects a most suitable network slice according to the received slice information list and combined with the service to be performed, and carries the slice indication inform...

Embodiment approach 2

[0084] Figure 9 It is a flowchart of a method for successfully selecting a suitable network slice for service when the UE actively performs services and carries service description information according to an optional embodiment of the present invention, as shown in Figure 9 As shown, the steps of the method include:

[0085] Step S902: UE prepares to actively perform services, and performs access on random access resources of the default service type;

[0086] Step S904: The network side receives the UE's random access request, and identifies the default service type according to the random access resource, then the UE can be accessed by referring to the existing LTE access procedure;

[0087] Step S906: UE sends MSG5 to the network side, which carries service description information;

[0088] Step S908: The network side selects a slice according to the service description information in the MSG5 message. If the service description information is empty, select a pre-confi...

Embodiment approach 3

[0091] Figure 10 It is a flowchart of a method in which a UE actively performs high-definition video services according to an optional embodiment of the present invention and successfully selects a suitable network slice for service, as shown in Figure 10 As shown, the steps of the method include:

[0092] Step S1002: The UE prepares to actively perform high-definition video services, and performs access on random access resources corresponding to category A according to the service type being ultra-high-speed services;

[0093] Step S1004: The network side receives the random access request, and recognizes that the ultra-high-speed service will be performed according to the random access resource;

[0094] Step S1006: the network side carries all the slice information (A1, A2) supported under the video service type A to the UE in the random access response message;

[0095] Step S1008: According to the service to be performed by the UE is high-definition video, the UE obt...

Abstract

The invention provides a network slice selection method and device. The method comprises the steps that a terminal sends a service request to a network side, wherein the service request carries the service type or service description information of a to-be-conducted service and is used for indicating the network side to select a network slice; the terminal receives an information list of the network slice which is determined by the network side and corresponds to the service type; the terminal determines a selection decision for indicating network slice selection according to the received information list; and the terminal sends network slice indication information selected according to the selection decision to the network side, wherein the network slice indication information is used for indicating location index information of the network slice in the information list or an identity (ID) of the network slice. According to the network slice selection method and device, the problem that in the prior art, network slice selection cannot be conducted is solved, and a blank in the related technique is filled.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for selecting network slices. Background technique [0002] The rapid development of mobile communication has penetrated into all aspects of people's work, social life, and life, and has brought a huge impact on people's life style, work style, social politics, economy and other aspects. Human society has entered the information age, and the demand for business applications in all aspects has shown explosive growth. In the future, mobile networks will not only provide communication between people, but also provide services for massive Internet of Things devices. Such as virtual reality, high-definition video and other services that require ultra-high-speed services, the rate can reach 10 to 100 times the current rate; Networking can access 1,000 times the current number of services, and the battery life can also be extended to 10 times the current one.
