Embodiment 2

[0086] Such as figure 2 As shown, Embodiment 2 of the present invention provides an authentication method in a network slice, which can be applied to a session management entity, and the method includes:

[0087] Step 21: Obtain the slice security policy when receiving the session establishment instruction sent by the mobility management entity;

[0088] Step 22: When the slice security policy indicates that the corresponding terminal is authenticated in the network slice, send a network slice authentication request and the slice security policy to the network slice authentication proxy entity.

[0089] The method for authenticating within the network slice provided by Embodiment 2 of the present invention obtains the slice security policy when receiving the session establishment instruction sent by the mobility management entity, and performs network During intra-slice authentication, send an authentication request in the network slice and the slice security policy to the n...

Embodiment 3

[0190] Such as Figure 6 As shown, Embodiment 3 of the present invention provides a network slice authentication proxy entity, including:

[0191] The first receiving module 61 is configured to receive the authentication request in the network slice and the slice security policy sent by the session management entity;

[0192] The first processing module 62 is configured to perform an intra-network slice authentication operation according to the intra-network slice authentication request and the slice security policy.

[0193] The network slice authentication proxy entity provided in Embodiment 3 of the present invention receives the network slice authentication request and slice security policy sent by the session management entity, and performs network slice authentication according to the network slice authentication request and the slice security policy. The operation of authentication in the slice; it can complete the authentication in the network slice, further guarantee...

Embodiment 4

[0204] Such as Figure 7 As shown, this embodiment provides a network slice authentication proxy entity, including:

[0205] Processor 71; and a memory 73 connected to the processor 71 through a bus interface 72, the memory 73 is used to store programs and data used by the processor 71 when performing operations, when the processor 71 calls and When executing the programs and data stored in the memory 73, the following processes are performed:

[0206] Receive the authentication request and slice security policy in the network slice sent by the session management entity through the transceiver 74;

[0207] An operation of authentication in the network slice is performed according to the authentication request in the network slice and the security policy of the slice.

[0208] Wherein, the transceiver 74 is connected to the bus interface 72 for receiving and sending data under the control of the processor 71 .

[0209] It should be noted that, in Figure 7 Among them, the b...

Abstract

The present invention provides an authentication method in a network slice, a network slice authentication proxy entity and a session management entity, wherein the authentication method in a network slice includes: receiving an authentication request in a network slice sent by a session management entity and a slice security Policy: perform an operation of authentication in the network slice according to the authentication request in the network slice and the security policy of the slice. This solution receives the authentication request and slice security policy in the network slice sent by the session management entity, and performs the authentication operation in the network slice according to the authentication request in the network slice and the slice security policy; it can complete the authentication in the network slice Authentication further guarantees slice security, and solves the problem that the slice security authentication scheme in the prior art is not perfect enough.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication method in a network slice, a network slice authentication proxy entity and a session management entity. Background technique [0002] The 3GPP SA3 (Third Generation Partnership Project Security Group 3) slice security aspect describes various key issues of network slice security, including network slice authentication. Network slice authentication can be divided into network slice authentication and network slice authentication. So far, there is no specific technical solution on how to implement authentication within the network slice. However, in order to ensure a high degree of slice security, authentication within the network slice is still required. Contents of the invention [0003] The purpose of the present invention is to provide an authentication method in a network slice, a network slice authentication proxy entity and a session manag...
