The embodiments of this application are described in the following with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are merely some rather than all of the embodiments of this application. All other embodiments obtained by a person skilled in the art based on the embodiments of this application fall within the protection scope of this application.
The terms “first” and “second” in the specification and claims of this application are used to distinguish similar objects, but are unnecessarily used to describe a specific sequence or order. It is to be understood that the terms used in this way are exchangeable in a proper case, so that the embodiments of this application described herein can be implemented in an order different from the order shown or described herein. The objects distinguished by “first” and “second” are generally in one class, and the number of objects is not limited. For example, there may be one or more first objects. In addition, “and/or” in the specification and claims represents at least one of the connected objects, and the character “/” generally represents that the associated objects are in an “or” relation.
It is to be noted that the technologies described in the embodiments of this application are not limited to a Long Term Evolution (LTE)/LTE-Advanced (LTE-A) system, and may, further be applied to other wireless communication systems such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-Carrier Frequency Division Multiple Access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are often used interchangeably. The technology described may be applied to the systems and radio technologies mentioned above, and may also be applied to other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes and uses the NR term in most of the following descriptions, but these technologies may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.
In order to facilitate a better understanding of the embodiments of this application, the following technical points are first described below.
SNPNs deployed by a PLMN have the same PLMN IDs correspondingly. For example, in a case that the PLMN IDs corresponding to SNPN1 and SNPN2 are the same, when an SNPN2 UE has accessed SNPN1, the same PLMN ID as an SNPN1 UE is provided. A Radio Access Network (RAN) provides an SNPN1 NID to an Access and Mobility management Function (AMF). Therefore, the AA/if may not distinguish whether an accessed UE is the SNPN1 UE or the SNPN2 UE, In addition, for example, in a case that SNPN1 is deployed by PLMN1, when both the SNPN1 UE and a PLMN1 UE access SNPN1, a SUbscription Permanent Identifier (SUPI) and/or a SUbscription Concealed Identifier (SUCI) in the format of an International Mobile Subscriber Identity (IMSI) may be provided. In this case, the SNPN1 UE and the PLMN1 UE provide the same NID to the RAN, and a Mobile Country Code (MCC)+a Mobile Network Code (MNC) of the SNPN1 UE and the PLMN1 UE received by the AMF are also the same. Therefore, the AMF may not distinguish whether the accessed UE is the SNPN1 UE or the PLMN1 UE.
At present, there are still the following problems to be solved:
Scenario 1 (shown in Table 1 below):
An access network is SNPN X.
The accessed UE is an SNPN X UE, an SNPN Y UE, or a PLMN Z UE.
For Scenario 1:
When a UE of SNPN Y accesses SNPN X, the same PLMN ID (999) as a UE of SNPN X is provided. An NID provided by the RAN to the AMF is an NID of SNPN X. Therefore, the AMF cannot distinguish whether the accessed UE is the UE of SNPN X or the UE of SNPN Y.
Scenario 2 (shown in Table 2 below):
An access network is SNPN X, and SNPN X is deployed by PLMN Z.
The accessed UE is an SNPN X UE, an SNPN Y UE, or a PLMN Z UE.
For Scenario 2:
When SNPN X is deployed by PLMN Z, both the UE of SNPN X and the UE of PLMN Z may provide a SUPI/SUCI in an IMSI format when accessing SNPN X. In this scenario, the UE of SNPN X and the UE of PLMN Z provide the same NID to the RAN, and the MCC+MNC of the UE of SNPN X and the UE of PLMN Z received by AMF are also the same. Therefore, the AMF may not distinguish whether the accessed UE is the UE of SNPN X or the UE of PLMN Z.
For the above two scenarios, two methods are provided:
Method 1:
All UEs may only use an SUI and/or SUCI in an NAI format when accessing the SNPN:
The SUPI and/or SUCI in the NAI format is composed of username @realm, where the realm part represents a home network of the UE.
Method 2:
When the UE accesses the SNPN through the SUPI and/or SUCI in the IMSI format, a selected NID and/or an index of the NID are provided to the RAN, and an NID and/or an index of the MD of the home network of the UE are additionally provided. The provision manners include an NAS message or an RRC message.

It is to be understood that the SUN and/or SUCI in the NM format is composed of username @realm, where the realm part represents a network to which the UE belongs. Therefore, the network-side device of the first network may accurately determine a network to which the UE belongs based on the SUPI and/or SUCI in the NAI format.
