[0049] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described as follows, which can be combined with the technical solutions of the embodiments of the present application in any way as optional schemes, and all belong to the protection scope of the embodiments of the present application.

[0050] 1) 5G technology overview

[0051] Currently, with the pursuit of rate, delay, high mobility, energy efficiency and the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization begins to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra reliability and low latency communication (URLLC), and massive machine type communications (mMTC).

[0052] eMBB still aims to enable users to obtain multimedia content, services and data, and its demand is growing rapidly. Since eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., its capabilities and requirements vary greatly and cannot be generalized. It must be analyzed in detail in combination with the specific deployment scenario. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), traffic safety assurance, etc. The typical characteristics of mMTC include high connection density, small data volume, delay-insensitive services, low-cost modules and long service life, etc.

[0053] In order to reduce air interface signaling and quickly recover wireless connection and data service in 5G network environment, a new radio resource control (RRC) state, i.e. RRC_INACTIVE state, is introduced. This state is different from RRC_IDLE and RRC_CONNECTED states.

[0054] RRC_IDLE: mobility is based on UE's 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 (AS) context in the base station side, and there is no RRC connection.

[0055] RRC_CONNECTED: there is an RRC connection, and there is a UE AS context in the base station and UE. The network side knows the location of the UE is specific to the cell level. Mobility is network-controlled mobility. Unicast data can be transmitted between the UE and the base station.

[0056] RRC_INACTIVE: mobility is based on UE's cell selection / reselection, and the CN is still in a connected state with the anchor RAN. The UE AS context exists in a certain base station. Paging is triggered by the radio access network (RAN), and the RAN-based paging area is managed by the RAN. The network side knows the location of the UE is based on the RAN-based paging area level.

[0057] 2) NR NPN network deployment features

[0058] NR R16 includes a non-public network (NPN) network. In order to increase the flexibility of NPN network deployment, the NPN network can be divided into stand-alone non-public networks (SNPN) and closed access groups (CAG) networks. The former identifies an SNPN network through a PLMN ID+NID (Network Identifier), and the latter identifies a CAG network through a PLMN ID+CAG ID.

[0059] A Public Land Mobile Network (PLMN) can simultaneously support any combination of network sharing modes among ordinary public networks, SNPN, and CAG networks. For example, a PLMN can support an ordinary public network, SNPN, or CAG network independently, or it can support an ordinary public network and SNPN sharing a single PLMN network, or even allow an ordinary public network, SNPN, and CAG network to share a single PLMN network simultaneously.

[0060] Figure 2 This diagram illustrates the network topology between ordinary public networks, SNPN, and CAG networks, providing a clearer picture of their interconnectedness. For example, a physical cell can be shared by multiple PLMN networks simultaneously, and each PLMN logical cell can establish its own unique non-public network. Figure 2 In the PLMN1 logical cell, a regular public network and three different CAG subnetworks are deployed simultaneously (see CAG ID1, CAG ID2, and CAG ID3). In the PLMN N-1 logical cell, only three SNPN subnetworks are deployed (see NID1, NID2, and NID3). This means that any network sharing combination of regular public networks, SNPN, and CAG networks can be freely deployed within a single PLMN. For example, it can be stipulated that the number of independent SNPN subnetworks, independent CAG subnetworks, or SNPN+CAG subnetworks deployed in a physical cell cannot exceed 12.

[0061] 3) Suitable cell: A cell in which the terminal can stay normally.

[0062] 4) Frequency priority

[0063] When configuring a frequency point, the network side can simultaneously configure its priority information. For example, the frequency point priority can range from 0 to 7, where 0 represents the lowest priority and 7 represents the highest priority. To allow for greater diversity in frequency point priority configuration, each priority value from 0 to 7 can be associated with a decimal place value. For example, the decimal place value range could be {0.2, 0.4, 0.6, 0.8}, resulting in a total of 40 possible frequency point priority combinations using both integer and decimal places.

[0064] Frequency priority can be configured via system information or dedicated signaling. The frequency priority configured via dedicated signaling is associated with a validity period. Within this validity period, the dedicated frequency priority always overrides the public frequency priority broadcast by the system information. When the validity period expires, the terminal can only use the public frequency priority.

[0065] 5) Cell selection and reselection rules for terminals in NPN networks

[0066] Cell selection: the cell selected by the terminal meets the suitable cell criteria, and the terminal can select to camp on the cell to complete cell selection.

[0067] Cell reselection: the target cell of reselection meets the suitable cell criteria and the reselection criteria defined based on absolute frequency priority, and the terminal reselects to the cell corresponding to the above conditions to complete cell reselection.

[0068] The reselection criteria defined based on absolute frequency priority described above can include the following three:

[0069] High priority frequency reselection criteria;

[0070] Equal priority frequency reselection criteria or same frequency reselection criteria, also known as R criteria;

[0071] Low priority frequency reselection criteria.

[0072] 6) Automatic Neighbor Relation (ANR)

[0073] Newly deployed cells will have an impact on the neighbor relation. The surrounding neighbor cells cannot always obtain the latest neighbor relation information from the operation and maintenance (OAM). NR allows the terminal to report the neighbor-related information obtained by itself under the configuration of the network side, such as cell global identity (CGI) and system frame number and frame timing difference (SFTD).

[0074] 7) Network side emergency communication service indication

[0075] The current network side emergency communication service indication information is configured in the granularity of a cell (Cell). That is, all PLMNs supported by the cell share one emergency communication service indication information, and these PLMNs either all support emergency communication or none of them support emergency communication. In addition, in NR R16, SNPN networks do not support emergency communication services.

[0076] SNPN and CAG NPN networks are becoming more and more flexible. Under the authorization of the operator, third parties can even deploy their own NPN networks. The current emergency communication permission is in the granularity of a cell, and SNPN networks do not even support emergency communication, which will result in very limited use of emergency communication, which is not conducive to the development of emergency communication services, and in serious cases, it will lead to situations where users are in danger but cannot initiate emergency communication.

[0077] Figure 3is a schematic flow chart of a grant configuration method 300 according to an embodiment of the present application. The method can optionally be applied to the system shown, but is not limited thereto. The method comprises at least part of the following. Figure 1 The system shown, but is not limited thereto. The method comprises at least part of the following.

[0078] S310, the terminal device receives grant configuration information, wherein the grant configuration information comprises an indication of an emergency communication service grant associated with an identity of at least one sub-network supported by a cell.

[0079] In embodiments of the present application, the type of the sub-network supported by the cell can comprise one or more of a public land mobile network (PLMN), a standalone non-public network (SNPN), a closed access group (CAG) network, a temporary network, and an access control related network. The PLMN has a PLMN ID, the SNPN has a SNPN ID, and the CAG network has a CAG ID. The SNPN ID can be represented by a combination of the PLMN ID and an NID.

[0080] It should be understood that the access control related network identity can be similar to the PLMN ID or the SNPN ID, i.e., the actual meaning is the same, but the length of the access control related network identity can be different from the PLMN ID or the SNPN ID. Similarly, the temporary network identity can be similar to the PLMN ID or the SNPN ID, i.e., the actual meaning is the same, but the temporary network identity is a temporary identity of the PLMN or the SNPN.

[0081] By way of example, the terminal device can receive the grant configuration information from a network device, such as a base station. The indication of the emergency communication service grant associated with the identity of the at least one sub-network supported by the cell in the grant configuration information can comprise the identity of the sub-network supported by the cell (the current cell) accessed by the terminal device and the associated emergency communication service grant indication information. The indication of the emergency communication service grant associated with the identity of the at least one sub-network supported by the cell in the grant configuration information can also only comprise the emergency communication service grant indication information. For example, if it is agreed in advance that the identity of all sub-networks supported by the cell is associated with the same emergency communication service grant indication information, the associated relationship in the grant configuration information can comprise the emergency communication service grant indication information.

[0082] Optionally, in embodiments of the present application, the grant configuration information is carried in a cell system broadcast message.

[0083] After the terminal device receives the cell system broadcast message, the terminal device can parse the grant configuration information from the message to obtain the indication of the emergency communication service grant associated with the identity of the at least one sub-network supported by the cell.

[0084] Optionally, in the embodiment of the present application, the terminal device receives the authorization configuration information, and the AS (Access Stratum) of the terminal device delivers the received authorization configuration information to the NAS (Non-Access Stratum) of the terminal device.

[0085] In the embodiment of the present application, if the AS of the terminal device receives the cell system broadcast message, the AS delivers the authorization configuration information in the cell system broadcast message to the NAS of the terminal device, indicating that the authorization configuration information is received successfully. The NAS can determine whether to initiate the emergency communication service by using the authorization configuration information. The emergency communication service can include, for example, fire alarm, public security alarm, rescue and disaster relief, public safety, and the like.

[0086] Optionally, in the embodiment of the present application, the method further includes: the terminal device determines the emergency communication service support situation of at least one sub-network supported by the accessed cell based on the authorization configuration information.

[0087] Exemplarily, the authorization configuration information received by the terminal device can include emergency communication service indication information of multiple sub-networks supported by the cell accessed by the terminal device. Based on the authorization configuration information, the terminal device can determine the emergency communication service support situation of one or more of the sub-networks.

[0088] For example, the authorization configuration information includes emergency communication service authorization indication information 1 associated with PLMN ID 1. And the emergency communication service authorization indication information 1 indicates that emergency service 1 is supported. The terminal device can determine that the PLMN identified by the PLMN ID 1 supports the emergency service 1.

[0089] For another example, the authorization configuration information includes emergency communication service authorization indication information 1 associated with PLMN ID 1 and emergency communication service authorization indication information 2 associated with PLMN ID 2. And the emergency communication service authorization indication information 1 indicates that emergency service 1 is supported, and the emergency communication service authorization indication information 2 indicates that emergency service 2 is supported. The terminal device can determine that the PLMN identified by the PLMN ID 1 supports the emergency service 1 and the PLMN ID 2 supports the emergency service 2, or only determine that the PLMN identified by the PLMN ID 1 supports the emergency service 1.

[0090] For another example, the authorization configuration information includes emergency communication service authorization indication information 1 associated with SNPN ID 1, SNPN ID 2 and SNPN ID 3. And the emergency communication service authorization indication information 1 indicates that emergency service 1 is supported. The terminal device can determine that the SNPN identified by the SNPN ID 1 supports the emergency service 1 and the SNPN identified by the SNPN ID 2 supports the emergency service 1.

[0091] Optionally, in the embodiment of the present application, the identification of the at least one sub-network supported by the cell comprises at least one of the following: a public land mobile network (PLMN) identification supported by the cell; an independent non-public network (SNPN) identification supported by the cell; a closed access group (CAG) identification supported by the cell; a temporary network identification; an access control related network identification.

[0092] Illustratively, the emergency communication service authorization indication information associated with the identification of the at least one sub-network supported by the cell can comprise at least one of the following:

[0093] The emergency communication service authorization indication information associated with the at least one PLMN identification supported by the cell;

[0094] The emergency communication service authorization indication information associated with the at least one SNPN identification supported by the cell;

[0095] The emergency communication service authorization indication information associated with the at least one CAG identification supported by the cell;

[0096] The emergency communication service authorization indication information associated with the at least one temporary network identification supported by the cell;

[0097] The emergency communication service authorization indication information associated with the at least one access control related network identification supported by the cell.

[0098] Optionally, in the embodiment of the present application, the configuration granularity of the authorization configuration information comprises at least one of the following: PLMN identification granularity; SNPN identification granularity; CAG identification granularity; temporary network identification granularity; access control related network identification granularity.

[0099] Optionally, in the embodiment of the present application, the authorization configuration information of the PLMN identification granularity comprises at least one of the following:

[0100] Each PLMN identification supported by the cell is associated with one emergency communication service authorization indication information.

[0101] For example, a plurality of PLMN identifications supported by a cell are PLMN ID1, PLMN ID2 and PLMN ID3 respectively. PLMN ID1 is associated with emergency communication service authorization indication information 1, PLMN ID2 is associated with emergency communication service authorization indication information 2, and PLMN ID3 is associated with emergency communication service authorization indication information 3.

[0105] Exemplarily, the plurality of SNPN identities supported by a cell is associated with an emergency communication service authorization indication information. Specifically, for example, the plurality of SNPN identities supported by a cell are SNPN ID1, SNPN ID2 and SNPN ID3 respectively.
