There are two types of current radio access technologies: 3GPP access technologies (e.g., third generation (3rd Generation,3G), fourth generation (4th Generation,4G), or wireless access technologies employed in 5G systems) and Non-3GPP (Non-3 GPP) access technologies. The 3GPP access technology refers to an access technology conforming to the 3GPP standard specification, for example, access network devices in a 5G system are referred to as next generation base station nodes (Next Generation Node Base Station, gNB) or RAN devices. Non-3GPP Access technologies may include air interface technologies typified by Access Points (APs) in wireless fidelity (Wireless Fidelity, wiFi), worldwide interoperability for microwave Access (Worldwide Interoperability For Microwave Access, wimax), code division multiple Access (Code Division Multiple Access, CDMA), etc. The AN device may allow interworking between the terminal device and the 3GPP core network using non-3GPP technology.

Terminal devices, which may also be referred to as user equipment, terminals, etc. The terminal device is a device with a radio transceiving function, which can communicate with one or more Core Networks (CN) via AN access Network device in the (R) AN. Can be deployed on land, including indoors or outdoors, hand-held, wearable, or vehicle-mounted; the device can also be deployed on the water surface, such as a ship, etc.; but may also be deployed in the air, for example on an aircraft, balloon or satellite, etc. The terminal device may be a Mobile Phone (Mobile Phone), a tablet (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented Reality (Augmented Reality, AR) terminal device, a wireless terminal in industrial control (Industrial Control), a wireless terminal in unmanned Driving (Self Driving), a wireless terminal in Remote Medical (Remote Medical), a wireless terminal in Smart grid (Smart grid), a wireless terminal in transportation security (Transportation Safety), a wireless terminal in Smart city (Smart city), a wireless terminal in Smart Home (Smart Home), or the like.

The (R) AN is used to provide a network access function for authorized user equipments in a specific area, and can use transmission tunnels of different qualities according to the level of the user equipments, the requirements of services, etc. For example, the (R) AN may manage radio resources to provide access services for the ue, thereby completing forwarding of control information and/or data information between the ue and the core network.

In the related art, a non-3GPP side in the multi-access network architecture accesses 5GC through N3IWF, TNGF, etc., and when UE registers to 5GC through the non-3GPP side, the access type (non-3 GPP access) is registered to unified data management (Unified Data Management, abbreviated as UDM), and the network issues an N3IWF key (N3 IWF key) to facilitate establishing an internet protocol security (Internet Protocol Security, abbreviated as IPSec) connection between UE and N3IWF in a subsequent session.

However, in view of the above-mentioned problem that the architecture is limited to commercialization of N3IWF/TNGF and cannot fall to the ground later, through analysis, the present disclosure proposes a method for a user equipment to register a 3GPP access and a non-3GPP access to a core network (e.g., 5 GC) simultaneously through a registration procedure of the 3GPP access side. Because the non-3GPP has no access network element with 5GC, the control plane signaling is required to be performed through the 3GPP access side, that is, the registration flow of the non-3GPP is required to be completed through the 3GPP side. An embodiment of the access method of the present disclosure is described below with reference to fig. 1.

Fig. 1 illustrates a flow diagram of an access method according to some embodiments of the present disclosure. As shown in fig. 1, the access method of this embodiment includes steps S102 to S104.

In step S102, the ue (terminal) sends a request to the core network through the 3GPP access network, where the request includes multiple access indication information, where the multiple access indication information is used to indicate that the registration of the 3GPP access and the non-3GPP access of the ue is performed.

The request is for example a registration request. For example, the request message in the 3GPP registration procedure may be multiplexed, but the content of the request message is modified to carry the indication information of multiple accesses.

In some embodiments, the user equipment sends the request in case the user equipment is located in a 3GPP service and non-3GPP service coverage area. In this area, the user has a multi-access network environment, and a 3GPP access network can be used to implement a multi-access registration procedure.

The indication information of multiple accesses is used to directly or indirectly indicate a registration type of the user equipment, i.e. to indicate that an access type of the user equipment is registered as 3GPP access and non-3GPP access. Therefore, after the network side equipment acquires the multi-access indication information, the network side equipment can execute the registration flow of the user equipment. For example, in the case where the core network supports multiple accesses, the core network device registers the access type of the user equipment as 3GPP access and non-3GPP access.

In some embodiments, the indication information of multiple access includes at least one of a registration type of multiple access registration, an indication that the user equipment supports a lightweight ats function.

The access type of the user equipment may be stored in the UDM, e.g. the access type of the user equipment, i.e. 3GPP access and non-3GPP access, may be registered with the UDM by the AMF in the core network. If the request does not carry multi-access indication information, for example, the general 3GPP registration flow, the access type of the user equipment registered by the AMF to the UDM is 3GPP access.

In some embodiments, the indication information of multiple accesses includes an indication that lightweight ats functionality is supported. The lightweight ats function is an ats function based on a lightweight architecture, that is, a function that does not include or use non-3GPP network elements such as N3IWF and tnff in the architecture. After receiving the request and acquiring the multi-access indication information, the network side can determine whether to perform multi-access registration according to whether the core network supports the lightweight ats function. That is, when the core network supports the lightweight ats function, multi-access registration is performed; in the case where the core network does not support the lightweight ats function, multi-access registration is not performed.

In some embodiments, in the case where the network side determines to perform multi-access registration, multi-access registration may be performed based on other of the registration flows of 3GPP access specified in the current standards and specifications. However, the registration type is different from the registration type of the current 3GPP access, for example, the registration types of the present disclosure are 3GPP access and non-3GPP access, which are not described herein.

In step S104, the user equipment receives a response message.

The response is used to indicate whether registration of the 3GPP access and the non-3GPP access is successful. In the case that the network side completes the registration flow, the response message is a registration response. For example, the indication information of the multiple access includes an indication of supporting a lightweight ats function. In the case that the core network supports the lightweight ats function, the ue receives a registration response sent by the core network.

In the case that the network side refuses the registration flow or the registration flow fails, the response message is a refusal message. For example, in case the core network does not support the lightweight ats function, the user equipment receives a rejection message.

After registration is completed, e.g., after the user device receives the registration response, the user device may initiate a lightweight multi-access session. That is, the user equipment may use the data network through at least one of 3GPP access and non-3GPP access. Thus, the user equipment can use the data network through various access modes.

The above embodiment performs multi-access registration by using the 3GPP registration procedure, so that the present disclosure can also implement registration of non-3GPP access under a lightweight multi-access architecture.

In some embodiments, where an AMF in the core network supports lightweight ats functionality, a request is sent to the AMF. The AMF registers the access type of the user equipment as a 3GPP access and a non-3GPP access. After registration is completed, a registration response is sent by the AMF. An embodiment of the access method of the present disclosure is described below with reference to fig. 2.

Fig. 2 shows a flow diagram of an access method according to further embodiments of the present disclosure. As shown in fig. 2, the access method of this embodiment includes steps S202 to S208.

In step S202, the user equipment supporting the lightweight ats is in a 3GPP service and non-3GPP service coverage area.

In step S204, the ue sends a request through a 3GPP access network (R) AN, where the request carries AN indication for supporting the lightweight ats ss function, so as to indicate that the ue has a capability for supporting the lightweight ats ss function. The network side selects to accept or reject the request based on whether the core network supports the capability of lightweight ats. For example, after the (R) AN determines that the user equipment supports the lightweight ats function, it selects AN AMF supporting the lightweight ats function, and the AMF continues to process the request.

In step S206, if the user equipment and the AMF both support the lightweight ats function, the AMF registers the access type of the user equipment to the UDM, where the access types are 3GPP access and non-3GPP access.

Other procedures are included in the registration procedures of the 3GPP access specified in the current standard and specification, and may be applied to the registration procedures of the 3GPP access and the non-3GPP access of the present disclosure, where only the registration type is changed, and will not be described herein.

If the network side does not support the lightweight ats function, the AMF returns a reject message to the user equipment.

In step S208, the AMF transmits a registration response to the user equipment. At this time, the user equipment may consider initiating a lightweight multi-access session. In case no network elements such as N3IWF, TNGF, etc. are included, the user plane data flows on the non-3GPP side may not be transmitted over the IPSec connection.

Through the embodiment, the registration flow of the 3GPP and the non-3GPP can be completed through the AMF supporting the lightweight ATSSS function, so that the multi-access registration of the user equipment can be realized under a lightweight architecture.

It should be noted that the above embodiments of the present disclosure may be applicable to a lightweight multi-access architecture, i.e., an architecture that does not include N3IWF, TNGF non-3GPP network elements. However, the above procedure of implementing non-3GPP access using 3GPP access may be equally applicable in case of including non-3GPP network elements in the network, as required.

Fig. 3 schematically illustrates a schematic diagram of a lightweight multi-access network architecture of the present disclosure. As shown in fig. 3, in the network 3, the UE 31 connects the AMF 33,3GPP access network 32 through the 3GPP access network 32 and the AMF 33 through the N1 and N2 interfaces, so that in the case that the AMF 33 supports multiple accesses, the UE 31 can complete a registration update procedure through the AMF 33 to realize multiple access registration of the 3GPP and the non-3 GPP; AMF 33 and SMF 34 are connected through an N11 interface, AMF 34 and PCF 35 are connected through an N7 interface, and SMF 34 and UPF 36 are connected through an N4 interface. After the multi-access registration is completed, the UE 31 may connect to the UPF 36 through the 3GPP access network 32, and further access to the data network 37 through the 3GPP side, where the UPF 36 and the data network 37 are connected through an N6 interface; also, the UE 31 may connect the UPF 36 through an IP (Internet Protocol, network protocol) network (e.g., wiFi or IP access) 38 to access the data network 37 through the non-3GPP side. Under the architecture, the UE no longer needs to access 5GC through network elements such as N3IWF or TNGF, but realizes a control plane flow of the non-3GPP side through the 3GPP access side, and the non-3GPP side only reserves a data plane flow. The access method disclosed by the invention is beneficial to the landing of the multi-access network function by supporting the simplified multi-access network.
