Description

Network access method, terminal and network side equipment

Technical Field

The application belongs to the technical field of communication technology, and particularly relates to a network access method, a terminal and network side equipment.

Background

In general, a 5G independent non-public network (SNPN) subscribed terminal is not supported to access a Public Land Mobile Network (PLMN). However, in the emergency service scenario, the terminal is allowed to register emergency with the PLMN network.

In the related art, when accessing the PLMN for service, the terminal only uses the terminal identifier in International Mobile Subscriber Identity (IMSI) format. But if the PLMN ID of the SNPN to which the terminal is subscribed is not unique, an additional Network Identification (NID) is required to identify the terminal to support authentication that may occur. However, PLMN networks do not currently support emergency services in NID and network-specific identifier (NSI) formats. Therefore, how to uniquely identify a terminal when the SNPN subscribed terminal accesses the PLMN needs to be solved.

Fig. 2 is a flowchart of a network access method according to an embodiment of the present application. As shown in fig. 2, the network access method is executed by a terminal. The network access method comprises the following steps:

200, under the condition that a first condition is met, the terminal executes a first operation;

wherein, in one embodiment, the first condition comprises at least one of:

the public land mobile network identification (PLMN ID) of the terminal's home network is unique, or the PLMN ID of the terminal's home network is not unique and the first network supports obtaining the network identification code (NID) of the terminal's home network by means other than the first type identification;

the first network does not support a network identification number, NID;

the identification information of the network that assigns the first type identifier to the terminal includes NID, and/or the network type of the network that assigns the first type identifier to the terminal includes: independent non-public network SNPN.

In another embodiment, the first condition includes at least one of:

In an optional embodiment of the present invention, the PLMN ID in the first type of identity of the terminal comprises at least one of: a PLMN ID of a home network of the terminal, a PLMN ID of a network to which the first type identifier is assigned.

In one embodiment, when the first type identifier is a permanent end user identifier (such as sui, or SUPI, or IMSI), the PLMN ID in the first type identifier is the PLMN ID of the terminal's home network. In one embodiment, when the first type identifier is a temporary end user identifier (e.g., GUTI, or 5G-GUTI), the PLMN ID in the first type identifier is a PLMN ID of a network to which the temporary end user identifier is assigned.

In one embodiment, the identification information of the home network of the terminal includes a PLMN ID and a NID, and if the PLMN ID of the home network of the terminal is not unique, for example, the IMSI of two terminals of different home networks may be the same, and if two terminals access the first network using the IMSI, the first network will not be able to distinguish between the two terminals. In one embodiment, the terminal is therefore unable to identify the network by the first type. Thus, in order to uniquely identify the terminal in the first network so that the terminal can access the first network, additional NIDs may need to be employed to identify the terminal to support authentication that may occur.

In one embodiment, the PLMN ID of the home network of the terminal is not unique, but said first network supports obtaining the network identification number NID of the home network of the terminal by means other than the first type of identity, the first type of identity being used by the terminal for accessing the first network and/or the third type of identity not being used for accessing the first network.

In one embodiment, if the PLMN ID in the first type identifier of the terminal is not unique, but the first network supports obtaining the network identifier NID of the network to which the first type identifier is assigned by means other than the first type identifier, the first network is accessed using the first type identifier, and/or the first network is accessed without using the third type identifier.

It should be noted that the first network support obtaining the network identification code NID of the home network of the terminal by means other than the first type identifier implicitly discloses that the first network supports NID.
