Description

Technical Field
The present invention relates to the field of communications technologies, and in particular, to a private network access method, relay UE, system, and storage medium.
Background
In the existing standard, a near-field communication mode is defined, and near-field communication means that in a base station signal free area, a remote UE (User Equipment) can access a mobile core network through relay UE transfer, or communication is directly performed between terminals. For access control of NPN (Non Public Network, non-public network), existing standards specify that a UE must sign up and be configured with specific private network information to access a private network-specific base station. For example, for PNI-NPN (Public Network Integrated NPN ) scenario, a terminal needs to sign up and configure a CAG (Closed Access Group ) corresponding to a private network to access a base station dedicated to the private network; for an SNPN (Stand-alone NPN) scene, a terminal needs to sign up and configure a PLMN ID and a Network ID corresponding to a private Network to access a base station special for the private Network. At present, for a UE that needs to access a private Network using a near-field communication method, there is a problem that the relay UE cannot access the private Network because the relay UE does not support configuration information (for example, CAG, PLMN ID, network ID, etc.) of the corresponding private Network.

Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Fig. 1 is a flow diagram of one embodiment of a private network access method according to the present disclosure, as shown in fig. 1:
step 101, the relay UE receives access information sent by the remote UE and used for accessing to the private network base station.
In one embodiment, the relay UE and the remote UE may be mobile phones, tablet computers, and the like. The private network includes a PNI-NPN network, an SNPN network, and the like. When the private network is a PNI-NPN network, the access information comprises CAG information, timer information and the like, and the timer information is used for indicating the duration of using the access information by the relay UE, which can be 1 hour, 2 hours and the like. When the private Network is an SNPN Network, the access information comprises information such as PLMN ID, network ID, timer information and the like.
The remote UE is in an area without a private network base station signal and the relay UE is in an area with a private network base station signal. And the relay UE receives the access information sent by the remote UE in the process of discovering the relay UE by the remote UE or after the remote UE discovers the relay UE. The remote UE may discover the relay UE using a plurality of existing discovery methods, and during or after the remote UE discovers the relay UE, the remote UE transmits access information for accessing the private network base station to the relay UE.
In step 102, the relay UE accesses the private network base station using the access information.
In one embodiment, the relay UE performs a corresponding configuration process based on the access information after receiving the access information, and accesses the private network base station after performing the configuration process. For example, when the private network is a PNI-NPN network, the relay UE performs corresponding configuration processing using information such as CAG information in the access information, and accesses a base station of the PNI-NPN network after performing the configuration processing. When the timer information in the access information is 1 hour, the relay UE accesses the private network base station and performs the subsequent transfer operation for 1 hour.
And 103, the relay terminal provides a relay service for the remote UE so that the remote UE can access the private network base station.
In one embodiment, the relay UE relays signaling information sent by the remote UE to the private network base station and forwards the signaling information sent by the private network base station to the remote UE, so that the remote UE accesses the private network base station and establishes a connection with the private network base station. The remote UE performs the transfer of the signaling through the relay UE, and can access the private network base station by using the existing signaling interaction flow. The relay UE forwards the data packet sent by the remote UE to the private network base station, and forwards the data packet sent by the private network base station to the remote UE.
The invention provides a private network access method, which aims at the problem that the current private network UE cannot be switched into a private network through a relay UE which does not sign or configure corresponding private network information, so that the use scene of near-field communication is limited, and the remote UE leases the information required by accessing a private network base station to the relay UE for use, so that the private network is switched in through the relay UE.
Fig. 2 is a flow chart illustrating another embodiment of a private network access method according to the present disclosure, as shown in fig. 2:
in step 201, the remote UE discovers the relay UE. The remote UE can discover the relay UE according to the existing standard procedure.

The information required for accessing the private network base station includes: 1) CAG, is used for inserting PNI-NPN; 2) PLMN ID and Network ID, which are used for accessing SNPN; 3) Other private network access information; the information required for accessing the private network base station may optionally include timer information for defining the duration of time that the relay UE uses the private network information.
In step 203, the relay UE applies the received information required for accessing the private network base station, and the relay UE accesses the private network base station.
In one embodiment, the relay UE immediately installs and applies the information required for access by the private network base station sent by the remote UE. Steps 202 and 203 may be performed sequentially after step 201, or may be performed simultaneously in the discovery process of step 201. And the relay UE successfully accesses the private network base station by utilizing the received information required by accessing the private network base station.
In step 204, the remote UE accesses the private network via the relay UE.
In one embodiment, the remote UE accesses the private network via the relay UE. The relay UE firstly relays the signaling of the remote UE, so that the remote UE is successfully accessed to the private network and establishes connection, and then relays the service data packet of the remote UE.
Fig. 3 is a schematic flow chart of a further embodiment of a private network access method according to the present disclosure, and fig. 3 is a flow chart of a 5G private network user (remote UE) accessing a PNI-NPN network through a relay UE, as shown in fig. 3:
in step 301, the remote UE discovers the relay UE according to the standard procedure.
In step 302, the remote UE sends private network access information to the relay UE. For example, the access information includes CAG information and a timer value (e.g., half an hour).
In step 303, the relay UE returns a response to the remote UE to confirm that the relevant private network access information has been received.
Step 304, the relay UE installs according to the access information and applies the information required by the private network access. For example, the relay UE attempts to access a base station of the PNI-NPN network using CAG information.
In step 305, the relay UE successfully accesses the private network base station.
