It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0043] Figure 1The present invention is a flowchart of some embodiments of the non-3GPP access method disclosed in the present invention, which is executed by a terminal that has signed a contract for a high-priority service. The terminal may also be referred to as UE (user equipment). The terminal is a device with wireless transceiver functions, which can communicate with one or more CNs (core networks) via access network devices in (R)AN ((radio) access network). It can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water, such as on a ship; it can also be deployed in the air, such as on an airplane, balloon or satellite. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, VR (virtual reality) terminal device, AR (augmented reality) terminal device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc.

[0044] In step 110, an authentication request message is sent to the network side device, wherein the authentication request message carries identification information to instruct the network side device to identify the priority of the predetermined service subscribed by the terminal during terminal authentication and establish a session connection corresponding to the priority.

[0045] The agreed service is, for example, a high priority service such as MPS, MCX, etc. The high priority here means that the priority is higher than that of ordinary services.

[0046] In some embodiments, the identification information is high-priority service information. For example, the user terminal initiates an EAP (Extensible Authentication Protocol) authentication request message, and adds information carrying high-priority services. For example, if the user subscribes to the MPS service, the MPS information is carried in the authentication request message, and if the user subscribes to the MCX service, the MCX information is carried in the authentication request message.

[0047] In some embodiments, the user terminal sends an authentication request message to the access gateway, and then the access gateway forwards the authentication request message carrying the information of the high-priority service to the network side device. The access gateway is, for example, a TWAN (Trusted WLAN Access Network) gateway, and the network side device is, for example, an HSS (Home Subscriber Server) or AAA (Authentication, Authorization, and Accounting). The TWAN gateway carries the information of the high-priority service in the authentication interaction process with the HSS / AAA. After the HSS / AAA identifies the information of the high-priority service, a session connection is established. For example, a PDN connection with high QOS (Quality of Service) is established, and more transmission resources and quality assurance are provided to the PDN connection subsequently.

[0048] In some embodiments, the identification information is carried in NAI (Network Access Identifier). NAI adds a high-priority service identification bit, for example, the identification information is set in the user name part or the beginning position of NAI, which is convenient for format unification on the one hand and for network side device identification on the other hand.

[0049] In step 120, when the authentication is completed, the core network is accessed through the non-3GPP based on the session connection.

[0050] In the above embodiment, the user terminal sends the priority information of the predetermined service subscribed by the terminal to the network side through the authentication request message, so that the network side can provide more resources for the terminal and provide higher priority service guarantee.

[0051] Figure 2 The present invention is a flowchart of other embodiments of the non-3GPP access method disclosed herein.

[0052] In step 210, the UE sends an authentication request message to the TWAN, where the authentication request message carries high-priority service information.

[0053] In some embodiments, the UE supports generating a NAI containing a high priority service identifier, for example, adding an identifier indicating high priority service information (eg, MCX, MPS, etc.) to a user name part of the NAI.

[0054] In the related art, the NAI format for registration to the EPC via a non-3GPP access network is as follows.

[0055] nai.epc.mnc <homemnc>.mcc <homemcc>.3gppnetwork.org!0 <imsi>@nai.epc.mnc <visitedmnc>.mcc <visitedmcc>.3gppnetwork.org

[0056] In this embodiment, the NAI format is as follows.

[0057] Priority <servicename>.nai.epc.mnc <homemnc>.mcc<homeMC C>.3gppnetwork.org!0 <imsi>@nai.epc.mnc <visitedmnc>.mcc<visit edMCC> .3gppnetwork.org

[0058] For example, if the user has signed up for the MPS service, the NAI format is as follows.

[0059] mps.nai.epc.mnc <homemnc>.mcc <homemcc>.3gppnetwork.org!0 <imsi>@nai.epc.mnc <visitedmnc>.mcc <visitedmcc>.3gppnet work.org

[0060] In some embodiments, the UE further supports sending an EAP authentication request containing a NAI with a high priority service identifier.

[0061] In step 220, TWAN performs an authentication and authorization process with HSS / AAA, and the authentication and authorization interaction process is added with high-priority service information.

[0062] In some embodiments, the TWAN supports receiving an EAP authentication request containing a NAI with a high priority service identifier, and supports using the NAI with a high priority service identifier for authentication and authorization procedures.

[0063] In some embodiments, the HSS / AAA supports receiving and identifying NAIs containing high-priority service identifiers, and supports using NAIs containing high-priority service identifiers for authentication and authorization procedures.

[0064] In the authentication and authorization process, and the interaction process between TWAN and HSS / AAA, network elements such as PDN GW (Packet Data Network Gateway) and PCRF (Policy and Charging Rule Function) are also used.

[0065] In step 230, TWAN establishes a PDN connection or a PDN session with HSS / AAA to ensure high priority services.

[0066] HSS / AAA identifies the high-priority service identification bit added to NAI, and establishes a PDN connection to guarantee the high-priority service according to the service priority corresponding to the identification bit.

[0067] In step 240, the EAP authentication ends. Subsequently, the UE can access the core network through the non-3GPP network.

[0068] In the above embodiment, information carrying high-priority services is added to the authentication / authorization request message of the UE. When the network side receives a request from a user who has signed up for a high-priority service, it can initiate the service first based on the high-priority service information in the request message and provide a higher-priority service guarantee.

[0069] Figure 3 The flowchart of some other embodiments of the non-3GPP access method disclosed in the present invention is shown in FIG. 1. The embodiment is executed by a network side device, such as HSS / AAA.

[0070] In step 310, an authentication request message sent by a terminal is received, wherein the authentication request message carries identification information.

[0071] In some embodiments, the identification information is carried in the NAI, for example, in the user name portion or the beginning position of the NAI.

[0072] In some embodiments, the identification information is high-priority service information. For example, if the user has signed up for the MPS service, "MPS" is added to the user name of the NAI.

[0073] In some embodiments, the network side device receives the authentication request message sent by the terminal through TWAN.

[0074] In step 320, the priority of the predetermined service subscribed by the terminal is identified according to the identification information.

[0075] In some embodiments, the HSS / AAA supports receiving and identifying NAIs containing high-priority service identifiers, and supports using NAIs containing high-priority service identifiers for authentication and authorization procedures.

[0076] In step 330, a session connection corresponding to the priority is established so that the terminal can access the core network through the non-3GPP based on the session connection when the authentication is completed.

[0077] In this embodiment, in the authentication / authorization request message, the terminal sends the scheduled service information to the network side. The network side learns the priority of the service and can provide more resources to guarantee the service, so that the network side can better protect high-priority services.

[0078] Figure 4 It is a schematic diagram of the structure of some embodiments of the terminal of the present disclosure. The terminal includes a message sending module 410 and an access module 420.

[0079] The message sending module 410 is configured to send an authentication request message to the network side device, wherein the authentication request message carries identification information to instruct the network side device to identify the priority of the predetermined service subscribed by the terminal during terminal authentication, and establish a session connection corresponding to the priority. The access module 420 is configured to access the core network through the non-3GPP based on the session connection when the authentication is completed.

[0080] The identification information is carried in the NAI, for example, in the user name part or the beginning position of the NAI. The identification information is, for example, high-priority service information.

[0081] In some embodiments, the terminal supports generating a NAI containing a high-priority service identification bit, and supports sending an EAP authentication request containing a NAI containing a high-priority service identification bit. A new identification indicating high-priority service information is added to the user name portion or the beginning position of the NAI, so that the network side is informed of the high-priority feature of the service, so that more resources are allocated to the high-priority service, and the service is guaranteed.
