This state is different from the RRC_IDLE (idle) and RRC_CONNECTED (connected) states. RRC_IDLE: Mobility is UE-based cell selection reselection, paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no UE access stratum (Access Stratum, AS) context on the base station side, nor does an RRC connection exist. RRC_CONNECTED: There is an RRC connection, and the UE AS context exists between the base station and the UE; the network device knows that the location of the UE is at the specific cell level. Mobility is the mobility of network device control. Unicast data can be transmitted between the UE and the base station.

For better understanding of the embodiments of the present application, an NPN network related to the present application is described.

NR R16 introduced NPN. In order to increase the flexibility of NPN deployment, NPN can be divided into SNPN and CAG networks. A SNPN is determined by PLMN ID and NID, and a CAG network is determined by PLMN ID and CAG ID (CAG ID). Taking SNPN as an example, the PLMN ID and NID can be used as an SNPN identifier. Users who have signed up for a SNPN service will configure the corresponding Subscriber Permanent Identifier (SUPI) and subscription information, which are stored in the terminal device and core. network side. A user who has subscribed to the SNPN service needs to support the SNPN access mode (SNPN access mode). The user configured in the SNPN access mode can only access the network through the SNPN, and the user who is not configured in the SNPN access mode can perform the PLMN selection process. The configuration mode (activation, deactivation, etc.) of the SNPN access mode is implemented by the terminal device. In the process of initial access and cell reselection, the access network equipment needs to broadcast the NID and corresponding PLMN ID information supported by itself. Users who have configured the SNPN access mode can select an accessible SNPN cell according to their own subscription information. The core network device may also authenticate the user's identity according to the user's subscription information.

A PLMN can support any combination mode of network sharing in common public network, SNPN and CAG network at the same time. For example, a PLMN can support the common public network, SNPN or CAG network alone, can also support the network sharing combined mode of common public network and SNPN, and even support the network sharing combined mode of common public network, SNPN and CAG network. In other words, the common public network, SNPN or CAG network can be supported by a PLMN, or the common public network and the SNPN can share a PLMN network at the same time, or even the common public network, SNPN and CAG network can share a PLMN network at the same time. The following table 1 can more clearly reflect the logical deployment relationship between the common public network, the SNPN and the CAG network.

Table 1

As shown in Table 1, from the perspective of network configuration, a cell can be configured with public network PLMN ID list information and non-public network NPN network identification list information at the same time, and non-public network NPN network identification list information is an optional parameter introduced by NR R16 , for a CAG-type NPN network, a PLMN ID is allowed to be associated with a CAG ID list; for an SNPN-type NPN network, a PLMN ID is allowed to be associated with a NID list.

The parameter N/M/W in Table 1 is a positive integer greater than or equal to 1.

FIG. 2 is a schematic diagram of a networking combination relationship among a common public network, an SNPN, and a CAG network provided by an embodiment of the present application. As shown in Figure 2, a physical cell can be shared by multiple PLMN networks at the same time, and each PLMN logical cell can form its own unique non-public network. Optionally, different physical cells can be distinguished by using Physical Cell Identities (Physical Cell Identities, PCI). For example, there are a total of 1008 physical cell identities in the NR system. PCI is a wireless signal used to distinguish different cells to ensure that there is no identical physical cell identity within the coverage of the relevant cells. Any network sharing combination of common public network, SNPN and CAG network can be freely deployed under a PLMN. Optionally, the number of independent SNPN sub-networks, the number of independent CAG sub-networks, or the total number of SNPN and CAG sub-networks deployed in one physical cell cannot exceed 12.

It should be noted that the "suitable cell" may refer to a cell where the terminal device can normally camp.

In order to facilitate a better understanding of the embodiments of the present application, the priority of frequency points related to the present application is described.

When configuring a frequency point on the network side, you can configure the frequency point priority information at the same time. The frequency point priority value ranges from 0 to 7. 0 represents the lowest priority, and 7 represents the highest priority. For the diversity of frequency priority configuration, The standard stipulates that each value from 0 to 7 can be associated with a decimal value. The value range of the decimal place is {0.2, 0.4, 0.6, 0.8}. There are a total of 40 frequency priority combinations with the combination of integer and decimal places.

The frequency point priority can be configured through system information or dedicated signaling. The frequency point priority configured by the dedicated signaling will be associated with a valid duration. During the valid duration, the dedicated frequency point priority always covers the public frequency point priority of system information broadcasting. level; when the valid time expires, the terminal can only use the public frequency priority.

It should be noted that, when configuring a frequency point on the network side, the frequency point priority of the frequency point configured at the same time is the absolute frequency point priority of the frequency point.

In order to facilitate a better understanding of the embodiments of the present application, the cell selection reselection rules of the terminals in the NPN network related to the present application are described.

Cell selection: The cell selected by the terminal satisfies the appropriate cell criterion, and the terminal can choose to camp in the cell to complete the cell selection.

Cell reselection: The reselected target cell satisfies the appropriate cell criterion and the reselection criterion condition defined based on the absolute frequency point priority, then the terminal reselects to the corresponding cell that satisfies the foregoing conditions to complete the cell reselection.

The above-mentioned reselection criteria defined based on absolute frequency priority include the following three:

High-priority frequency re-selection criteria;

The same-priority frequency point reselection criterion or the same-frequency reselection criterion, also known as the R criterion;

Low-priority frequency re-selection criteria.

The establishment of an NPN network by a third-party entity is a new requirement for NPN network deployment, such as temporary concert communication and temporary emergency communication. It is not an efficient network construction model to rely on operators to provide temporary NPN network deployment every time. With the growing demand for various third-party NPN network deployment, it seems more efficient for operators to allow third parties to build their own networks through protocol authorization.

However, once the operator authorizes a third-party entity to establish its own NPN network, the NPN network officially deployed by the operator and the NPN network deployed by the third-party entity will coexist. In this case, how to determine the frequency priority? is a problem that needs to be solved.

Based on the above problems, the present application proposes a solution for determining the priority of the frequency points. The terminal device can determine the frequency point priority of the serving cell frequency point and its adjacent frequencies, so that the cell selection or cell selection can be performed based on the determined frequency point priority. Cell reselection to improve system performance.
