Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another.

At present, a new type of network, non-public network (NPN), is introduced in the related art. The NPN may be deployed in various ways, and may be either independent of an existing 5G Public Network deployment (SNPN), that is, an independently deployed Non-Public Network, or may be deployed on an existing 5G Public Network in a shared manner (PNI-NPN: public Network integrated NPN). In the prior art, the customized information and the authentication information of the user are both stored in the SNPN network, and the UE needs to use the authentication information corresponding to the SNPN network to access the SNPN network. Therefore, in the prior art, the UE can only move between cells in the selected SNPN network, that is, the UE can only perform cell reselection or cell handover in the selected SNPN network.

However, after enhancing the SNPN technology, the subscription information and the authentication information of the UE accessing the SNPN may be stored in a Network entity other than the SNPN, such as a 5G Public Network (PLMN), as shown in fig. 1 (where a Unified Data Management entity: UDM, unified Data Management, PDU Session Anchor point: PSA, PDU Session Anchor), a Network interface is configured between the SNPN and the PLMN, and the UE using a Subscriber identity Module (SIM card, SIM) provided by a Public Network operator will be able to access the SNPN Network, and when the UE is registered in the SNPN Network, the authentication of the UE will be performed through the PLMN. That is, the related art will support the UE to access the SNPN network using PLMN subscription data and authentication information.

Since there may be multiple SNPNs that can be accessed using subscription data and authentication information of the same PLMN, mobility between different SNPNs (authenticated using the same PLMN authentication information) and between SNPNs (authenticated using the same PLMN authentication information) and PLMNs will be supported. That is, as shown in fig. 2, cell reselection or handover is allowed for multiple SNPNs authenticated using the same PLMN, or between an SNPN authenticated using a PLMN and a corresponding PLMN. That is, cell reselection or cell handover between SNPN and between SNPN/PLMN will be supported in the related art.

To support the new function, the Next Generation Radio Access Network (SNPN) needs to acquire the association information between the SNPN and before the SNPN and the PLMN for cell handover, but the currently defined Network interface message does not support transmission of the above information. That is, in the prior art, the 5G access network cannot acquire the relevant information of which SNPNs or SNPNs/PLMNs can be cell-handed over, and cannot support cell-handed over between networks.

Referring to fig. 3, fig. 3 is a schematic flowchart of an information transmission method according to an embodiment of the present invention, where the method is applied to a first terminal, and includes the following steps:

301. the first terminal receives a first network list sent by first core network equipment; the first network list comprises at least two networks, wherein the at least two networks comprise N independently deployed non-public networks and M public networks, and N and M are integers greater than or equal to zero;

That is, the first network list may include both SNPN (i.e., independently deployed non-public network) and PLMN, or may include both SNPN and PLMN. Alternatively, the first network list may include zero or one or more SNPNs, and may include zero or one or more PLMNs. In addition, cells belonging to networks in the first network list can each be used for cell selection, reselection and/or handover of the first terminal.

The first netlist may be referred to as an Equivalent Network list (Equivalent Network list). It should be noted that the equivalent network of the network to which the first terminal is currently registered includes a network that can be authenticated through the same network (for example, the equivalent network may be a network that can be authenticated through the registered network), and/or a network that has entered into a relevant agreement with the registered network. The equivalent network list is defined with reference to an existing equivalent PLMN list, except that the equivalent network list may include SNPN or only SNPN. The Equivalent PLMN List is a PLMN List (List of PLMNs associated as Equivalent by the UE for cell selection, cell reselection, and handover access to the information reconstructed by the NAS) which is considered by the UE according to the information provided by the NAS.

Specifically, the first network list includes the identifiers of the at least two networks.

In the embodiment of the present invention, a terminal may obtain a first network list, all networks in the first network list are equivalent networks of a network to which the first terminal is currently registered, and cells belonging to the networks in the first network list may be used for cell selection, reselection and/or handover of the first terminal. When cell selection, reselection and/or handover is triggered, a first target cell of one of the networks in the first network list can be selected, reselected and/or handed over, so that handover of the terminal between different networks can be realized.

Specifically, the first terminal receives the first network list sent by a core network through Non-Access Stratum (NAS) signaling (or referred to as NAS message).

The cell definition corresponding to the first netlist can be referred to tables 1 and 2.

TABLE 1

TABLE 2

the non-access layer sends the received first network list to an access layer;

Thereby, the first terminal is allowed to select and/or reselect to any one of the networks in the first network list when cell selection and/or handover is triggered.

For example, it shows that a UE receives a first network list sent by an SNPN core network (SNPN 5 GC) through a NAS message, and the UE reselects to other networks in the first network list (which may also be referred to as an equivalent network list) in an IDLE state (RRC _ IDLE) or an INACTIVE state (RRC _ INACTIVE): referring to fig. 4, a 5gc (SNPN 1) transmits a first network list to a UE through a NAS message; the UE NAS layer sends the first network list to a Radio Resource Control (RRC) layer; in an idle state or an inactive state, the UE reselects to a neighboring cell corresponding to SNPN2 (or PLMN 1) in the first network list.

Referring to fig. 5, fig. 5 is a flowchart illustrating an information transmission method according to a second embodiment of the present invention, where the method is applied to a first access network device, and includes the following steps:

501. the first access network equipment receives a first network list sent by first core network equipment; the first network list comprises at least two networks, wherein the at least two networks comprise N independently deployed non-public networks and M public networks, and N and M are integers greater than or equal to zero;

all networks in the first network list are equivalent networks of the network in which the first terminal is currently registered, and when the cell switching of the first terminal is triggered, the first terminal can be switched to a first target cell of one network in the first network list. That is, the first access network device may select a cell of a network in the first network list as a handover target cell at the time of cell handover. Of course, the cell selected as the handover target cell is a cell adjacent to the current serving cell of the first terminal.

That is to say, the first network list may have both SNPN (i.e. independently deployed non-public network) and PLMN, or may all be SNPN or PLMN. Alternatively, the first network list may include zero or one or more SNPNs, and may include zero or one or more PLMNs. In addition, cells belonging to the networks in the first network list can all be used for cell handover of the first terminal.

The first netlist may be referred to as an Equivalent Network list (Equivalent Network list). It should be noted that the equivalent network of the network to which the first terminal is currently registered includes a network that can be authenticated through the same network (for example, the network may be a network that can be authenticated through the registered network), and/or a network that has signed a relevant agreement with the registered network. The equivalent network list is defined with reference to an existing equivalent PLMN list, except that the equivalent network list may include SNPN or only SNPN. The Equivalent PLMN List is the PLMN List that the UE regards as the UE for cell selection, cell reselection and handover according to the information provided by the NAS (Equivalent PLMN List: list of PLMNs subscribed as Equivalent by the UE for cell selection, cell reselection, and handover accessing to the information reconstructed by the NAS).

In the embodiment of the present invention, an access network device may obtain a first network list, where all networks in the first network list are equivalent networks of a network to which the first terminal is currently registered, and cells belonging to the networks in the first network list may be used for cell selection, reselection, and/or handover of the first terminal. When the cell switching of the first terminal is triggered, the first terminal can be switched to a first target cell of one network in the first network list, so that the terminal can be switched among different networks.

Optionally, after receiving the first network list sent by the first core network, configuring the first terminal in a CONNECTED state (RRC _ CONNECTED) to measure neighboring cells belonging to the at least two networks (that is, neighboring cells belonging to networks in the first network list), and switching the first terminal to a target cell of one of the networks (that is, the first target cell) according to a measurement result.

Optionally, if the first network list includes two or more non-public networks, the two or more non-public networks are: a non-public network that can use the same public network for authentication, or a non-public network that has signed a related agreement.

Optionally, the method further includes:

and in the cell switching process, sending the first network list to a second access network device through an interface (namely an Xn interface) between the access network devices, wherein the second access network device is an access network device corresponding to the first target cell.

Optionally, the first access network device receives the first network list sent by the first core network device through an added information element in an NG interface message.

For example, it shows a method for an access network device (NG-RAN) to receive a first network list sent by an SNPN core network (SNPN 5 GC) and control a UE to switch to other networks in the first network list: referring to fig. 6, the 5gc (SNPN 1) sends the first net list to the NG-RAN (SNPN 1) through the NG interface message; when the UE is in a CONNECTED state (RRC _ CONNECTED), the NG-RAN (SNPN 1) configures the UE to measure a neighbor cell corresponding to a network (SNPN 2 or PLMN 1) in a first network list; and the NG-RAN (SNPN 1) controls the UE to be switched to a cell corresponding to the SNPN2 (or PLMN 1) according to the measurement result.

Referring to fig. 7, fig. 7 is a flowchart of an information transmission method according to a third embodiment of the present invention, where the method is applied to a first core network device, and includes the following steps:

701. the first core network equipment sends the first network list to the first access network equipment and/or the first terminal;

The first netlist may be referred to as an Equivalent Network list (Equivalent Network list). It should be noted that the equivalent network of the network to which the first terminal is currently registered includes a network that can be authenticated through the same network (for example, the equivalent network may be a network that can be authenticated through the registered network), and/or a network that has entered into a relevant agreement with the registered network. The equivalent networks list is defined with reference to an existing equivalent PLMN list, except that the equivalent networks list may include SNPNs or only SNPNs. The Equivalent PLMN List is a PLMN List (List of PLMNs associated as Equivalent by the UE for cell selection, cell reselection, and handover access to the information reconstructed by the NAS) which is considered by the UE according to the information provided by the NAS.

In the embodiment of the present invention, a first access network device and/or a first terminal may obtain a first network list, all networks in the first network list are equivalent networks of networks in which the first terminal is currently registered, and cells belonging to the networks in the first network list may be used for cell selection, reselection and/or handover of the first terminal.
