example 1

[0173] The network attachment request message is message 1, and the UE's network attachment procedure may include the following: Figure 6 Steps shown:

[0174] Step B1, UE sends IKE_SA_INIT-Request message to ePDG1.

[0175] Among them, the IKE_SA_INIT-Request message can be message 1, which carries the encryption algorithm supported by the UE and exchanges nonces, which is used to trigger the UE to interact with ePDG1 to complete the key exchange algorithm (Diffie_Hellman) exchange, and then prepare to establish IKE connect.

[0176] Step B2, when ePDG1 processes the IKE_SA_INIT-Request message abnormally, ePDG1 sends HO_REQUEST message to neighboring ePDG2.

[0177] Step B3. When ePDG1 receives the HO_ALLOW message sent by ePDG2, ePDG1 sends an IKE_SA_INIT-Request message to ePDG2, and sends an IKE_UPDATE message to the UE.

[0178] Wherein, the IKE_UPDATE message carries information such as the IP of the ePDG2, and is used to notify the UE to update the information of the...

example 2

[0206] The network attach request message is message 2, and the UE's network attach procedure may include the following: Figure 7 Steps shown:

[0207] Step C1, UE sends IKE_SA_INIT-Request message to ePDG1.

[0208] Among them, the IKE_SA_INIT-Request message carries the encryption algorithm supported by the UE and exchanges nonces, which is used to trigger the UE to interact with ePDG1 to complete the key exchange algorithm (Diffie_Hellman) exchange, and then prepare to establish an IKE connection.

[0209] Step C2, ePDG1 processes IKE_SA_INIT-Request, and sends IKE_SA_INIT-Answer message to UE.

[0210] Wherein, the IKE_SA_INIT-Answer message may be a network attachment response message, and the IKE_SA_INIT-Answer message carries information of the ePDG1.

[0211] In step C3, the UE sends an IKE_AUTH_Req message to the ePDG1, and performs an EAP algorithm negotiation process with the network side.

[0212] Among them, the IKE_AUTH_Req message in step C3 may carry SA inf...

example 3

[0240] The network attach request message is message 3, and the UE's network attach process may include the following: Figure 8 Steps shown:

[0241] Step D1, UE sends IKE_SA_INIT-Request message to ePDG1.

[0242] Among them, the IKE_SA_INIT-Request message carries the encryption algorithm supported by the UE and exchanges nonces, which is used to trigger the UE to interact with ePDG1 to complete the key exchange algorithm (Diffie_Hellman) exchange, and then prepare to establish an IKE connection.

[0243] Step D2, ePDG1 processes IKE_SA_INIT-Request, and sends IKE_SA_INIT-Answer message to UE.

[0244] Wherein, the IKE_SA_INIT-Answer message may be a network attachment response message, and the IKE_SA_INIT-Answer message carries information of the ePDG1.

[0245] In step D3, the UE sends an IKE_AUTH_Req message to the ePDG1, and performs an EAP algorithm negotiation process with the network side.

[0246] Among them, the IKE_AUTH_Req message in step C3 may carry SA infor...

Abstract

The embodiment of the invention provides a network attachment method, a gateway and user equipment, relates to the technical field of communication, and aims to solve the problem that the UE cannot beattached to a 3GPP network for a long time and cannot execute a VoWiFi registration process for a long time. The method is applied to a first gateway, and comprises the following steps: receiving a network attachment request message from user equipment UE; when the network attachment is abnormal, sending a network attachment request message to a second gateway, wherein the attachment request message is used for requesting to attach to a 3rd generation partnership project (3GPP) network through an untrusted wireless fidelity (Wi-Fi) network. The method is specifically applied to the network attachment process initiated when the UE executes the VoWiFi service.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a network attachment method, a gateway, and user equipment. Background technique [0002] Currently, for Wi-Fi-based voice (Voice over Wireless Fidelity, VoWiFi) services, user equipment (User Equipment, UE) can attach (access) the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP ) network to access the IP Multimedia Subsystem (IPMultimedia Subsystem, IMS) network, thereby registering VoWiFi and executing VoWiFi services. That is, the UE may attach to the 3GPP network through an untrusted Wireless Fidelity (Wi-Fi) network. [0003] Specifically, the UE may initiate an attach request message to an evolved packet data gateway (evolution Packet Data Gateway, ePDG), so as to request to attach to the 3GPP network. However, due to factors such as a poor load state of the ePDG (for example, a high load), the process of U...
