[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0022] First, the terms in this application are introduced accordingly:

[0023] 1) Non-public network (NPN);

[0024] In industrial environments, many applications (such as manufacturing and automated control) have high performance requirements, such as low latency and high reliability. These performance requirements are difficult to meet on local networks as device density increases. However, wireless links can replace traditional wired links. 5G communication networks can provide a LAN-style private communication service for these vertical industries, meeting their communication needs.

[0025] Currently, 3GPP has agreed to adopt the following two non-public network (NPN) deployment methods to support communication applications in vertical industries: The first is standalone NPN (SNPN) deployment, which does not rely on the public network. The non-public network identifier (such as SNPN ID) provided by the network side facilitates the user terminal (UE) to determine whether it can reside on a certain network. For example, traditional UE (such as UE that does not support SNPN access) cannot normally reside on the cell corresponding to the SNPN network, and SNPN UE can no longer normally reside on the cell corresponding to the Public Land Mobile Network (PLMN) network. UE with SNPN capability can work in SNPN mode or PLMN mode. When the UE works in SNPN mode, it can only access the network through SNPN. When working in PLMN mode, it can only access the network through PLMN.

[0026] The second type is non-independent NPN deployment (Public Network Integrated NPN, PNI-NPN), which relies on the public network. The concept of Closed Access Group (CAG) is introduced in this deployment scenario to facilitate the control of UE access to specific cells. When the UE subscribes to the NPN service, it will indicate the CAG to which the UE belongs, and the cell will provide the CAG identifier it supports to facilitate the UE to determine whether it can access a certain cell. If the access group to which the UE belongs is CAG1, and the access groups supported by a cell are CAG1 and CAG2, the UE can determine that the cell is accessible. If a cell only supports access group CAG2, the UE can determine that the cell is inaccessible.

[0027] 2)RAN sharing;

[0028] Radio Access Network (RAN) sharing refers to multiple operators sharing the same radio access network. In non-public network deployment scenarios, non-public networks (such as networks identified by SNPN IDs) and public networks (such as networks identified by PLMN IDs) can also share a radio access network. NR can support up to 12 network sharing (such as networks identified by PLMN IDs and / or networks identified by SNPN IDs and / or networks identified by PLMN ID + CAG IDs).

[0029] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following description, although these technologies can also be applied to applications other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0030] FIG1 shows a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal device or a user terminal (UE). The terminal 11 may be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (Pedestrian User Equipment, PUE) and other terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, where the base station can be called a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0031] The following describes in detail the control method for obtaining emergency services provided by the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0032] FIG2 is a flow chart of a control method for obtaining emergency services according to an embodiment of the present application. The method is applied to a terminal. As shown in FIG2 , the method includes the following steps:

[0033] Step S202: obtaining access control information provided by the cell, wherein the access control information is used to indicate whether the terminal operating in the target network mode is allowed to obtain emergency services;

[0034] Step S204: If the network mode in which the terminal operates matches the target network mode and the access control information indicates that the terminal operating in the target network mode is allowed to obtain emergency services, determine the cell as a cell in which emergency services can be obtained.

[0035] It can be seen from the above steps S202 and S204 that when the target network mode indicated by the access control information provided by the cell matches the network mode in which the terminal itself works and the access control information indicates that the terminal working in the target network mode is allowed to obtain emergency services, the terminal can determine that the cell is a cell where emergency services can be obtained, that is, the terminal can quickly distinguish whether emergency services can be obtained based on the access control information provided by the cell, avoiding unnecessary attempts by the terminal, and solving the problem in the prior art that the terminal cannot obtain emergency services in a timely manner because it cannot distinguish which network provides the emergency services.

[0036] Optionally, in another optional implementation of the embodiment of the present application, if the current network mode of the terminal does not match the target network mode, or the access control information indicates that the terminal operating in the target network mode is not allowed to obtain emergency services, the cell is determined to be a cell in which emergency services cannot be obtained. In other words, the terminal can determine whether emergency services can be initiated in the cell based on the access control information.

[0037] Furthermore, in an embodiment of the present application, when the current network mode of the terminal does not match the target network mode, or the access control information indicates that the terminal operating in the target network mode is not allowed to obtain emergency services, the cell is disabled.

[0038] It should be noted that the terminal operating in the target network mode in the embodiment of the present application is a terminal in a restricted service state.

[0039] Optionally, the target network mode in the embodiment of the present application may include an independent non-public network SNPN mode and a public land mobile network PLMN mode. Furthermore, the terminal operating in the SNPN mode in the embodiment of the present application may include: a terminal having SNPN capability and operating in the SNPN mode; and the terminal operating in the PLMN mode may include: a terminal having SNPN capability and operating in the PLMN mode, a terminal having closed access group CAG capability, and a terminal having neither SNPN capability nor CAG capability. It can be understood that the SNPN capability of a terminal is equivalent to the SNPN access capability, and the CAG capability is equivalent to the CAG access capability.

[0040] It should be noted that the terminal without SNPN capability and CAG capability is a traditional terminal.

[0041] Optionally, the type of the cell in the embodiment of the present application includes at least one of the following:

[0042] 1) A cell that supports both PLMN and SNPN access is a cell that can provide both PLMN and SNPN access; for example, a cell that can provide access to one or more public networks (public networks are identified by PLMN IDs) and access to one or more independently deployed non-public networks (independently deployed non-public networks are identified by SNPN IDs).

[0043] 2) Cells that support SNPN, PLMN and closed access group CAG access, that is, cells that provide SNPN, PLMN and CAG access; such as cells that can provide one or more public network access (identified by PLMN ID) and one or more independently deployed non-public network access (identified by SNPN ID) and one or more non-independently deployed non-public network access (identified by PLMN ID+CAG ID).

[0044] 3) Cells that support SNPN and CAG access, that is, cells that provide SNPN and CAG access; such as cells that can provide one or more independently deployed non-public network access (identified by SNPN ID) and one or more non-independently deployed non-public network access (identified by PLMN ID+CAG ID).

[0045] 4) Cells that support SNPN access, which can provide SNPN access; for example, cells that can provide one or more non-public network accesses (identified by SNPN ID).

[0046] Optionally, the access control information in the embodiment of the present application includes at least one of the following: first indication information and second indication information; wherein the first indication information is used to indicate whether the terminal working in SNPN mode is allowed to obtain emergency services; the second indication information is used to indicate whether the terminal working in PLMN mode is allowed to obtain emergency services.

[0047] The following is an example of the first instruction information.

[0048] The first indication information may be per-cell indication information, for example, SIB1 carries per-cell indication information (such as one-bit indication information). When the indication information takes a value of "1", it indicates that UEs working in SNPN mode are supported to obtain emergency services from the cell. When the value is "0", it indicates that UEs that do not support SNPN mode obtain emergency services from the cell. Alternatively, when SIB1 contains or carries per-cell indication information (such as one-bit indication information), it indicates that UEs that support SNPN mode obtain emergency services from the cell. When SIB1 does not contain or does not carry per-cell indication information (such as one-bit indication information), it indicates that UEs that do not support SNPN mode obtain emergency services from the cell. Exemplarily, if the first indication information is per-cell indication information, then when all independently deployed non-public networks sharing the cell cannot provide emergency services, the network side sets the first indication information for UEs that do not support SNPN mode to obtain emergency services. Otherwise, the first indication information is set for UEs that support SNPN mode to obtain emergency services. For example, cell A can support two independently deployed non-public network accesses, SNPN1 and SNPN2 (in other words, two independently deployed non-public networks, SNPN1 and SNPN2, share cell A). When neither SNPN1 nor SNPN2 supports the provision of emergency services, the network sets the first indication information for UEs that do not support SNPN mode to obtain emergency services. If the first indication information is a one-bit indication, the one bit is set to "0". Or the first indication information is not carried. Or,

[0049] The first indication information may also be per SNPN indication information, such as a one-bit indication information or a bitmap, wherein each bit in the bitmap corresponds to an independently deployed non-public network; in a specific application scenario, such as cell 1 supporting two independently deployed non-public network accesses, SNPN1 and SNPN2, there is an indication information for each independently deployed non-public network (such as SNPN1). When the indication information value is "1", it indicates that the corresponding independently deployed non-public network (such as SNPN 1) can provide emergency services, and the UE in SNPN mode can obtain emergency services through the independently deployed non-public network. When the indication information value is "0", it indicates that the corresponding independently deployed non-public network (such as SNPN 1) does not provide emergency services, and the UE in SNPN mode cannot obtain emergency services through the independently deployed non-public network. Alternatively, when the network side provides (such as the presence of indication information in SIB1) per SNPN indication information (such as one-bit indication information), it indicates that the corresponding independently deployed non-public network (such as SNPN 1) can provide emergency services, and the UE in SNPN mode can obtain emergency services through the independently deployed non-public network. When the network does not provide (such as the absence of indication information in SIB1) per SNPN indication information (such as one-bit indication information), it indicates that the corresponding independently deployed non-public network (such as SNPN 1) does not provide emergency services, and the UE in SNPN mode cannot obtain emergency services from the independently deployed non-public network.

[0050] For the second indication information, in a specific application scenario, it can also be indicated by bit information whether emergency services can be obtained. The method is similar to that of the first indication information and will not be repeated here.

[0051] Based on the first indication information, the terminal in the embodiment of the present application may determine whether to initiate an emergency service in the cell according to the first indication information in the following manner:

[0052] 1) If the obtained access control indication information indicates that the cell supports UE in SNPN mode to obtain emergency services, if the UE is a UE in SNPN mode (such as a UE in restricted service mode), the UE determines that it can obtain emergency services from the cell; for example, when the network side provides (such as carried in SIB1) per cell indication information, the indication information indicates that the cell supports providing emergency services to UE in SNPN mode, the UE in SNPN mode determines that it can obtain emergency services from the cell; or, when the network side provides (such as indication information exists in SIB1) per SNPN indication information, when at least one indication information indicates that its corresponding independently deployed non-public network supports the provision of emergency services, the UE in SNPN mode determines that it can obtain emergency services from the cell.

[0053] 2) If only the acquired access control indication information indicates that the cell supports UEs in SNPN mode to obtain emergency services, if the UE is a UE in PLMN mode, the UE (such as a UE in limited service mode) determines that it cannot obtain emergency services from the cell.

[0054] 3) If only the acquired access control indication information indicates that the cell supports UE in PLMN mode to obtain emergency services, if the UE is a UE in SNPN mode (such as a UE in restricted service mode), the UE determines that it cannot obtain emergency services from the cell.

[0055] Optionally, the method steps in the embodiment of the present application may further include: when the network mode in which the terminal operates matches the target network mode and the access control information indicates that the terminal operating in the target network mode is allowed to obtain emergency services, determining that the cell that can obtain emergency services is a candidate cell for cell selection or reselection. Furthermore, it is also possible to determine that the cell that can obtain emergency services is a high-priority candidate cell for cell selection or reselection, that is, if there are multiple candidate cells (for example, including cells that can obtain emergency services and cells that cannot obtain emergency services), the cell that can obtain emergency services can be preferably selected as a candidate cell for cell selection or reselection.

[0056] Optionally, in the embodiment of the present application, the method of obtaining the access control information provided by the cell involved in step S202 may further include: obtaining the access control information provided by the cell through an access layer.

[0057] Based on this, after obtaining the access control information provided by the cell through the access layer, the method of the embodiment of the present application may further include: inputting the access control information to the non-access layer through the access layer.

[0058] Based on this, after obtaining the access control information provided by the cell through the access layer, the method of the embodiment of the present application may also include: inputting network identification information to the non-access layer through the access layer, wherein the network identification information is used to identify the target network corresponding to the access control information.

[0059] It should be noted that the network identifier indicated by the network identification information can be one, as indicated by the above-mentioned per SNPN indication information; the network identifier indicated by the network identification information can also be multiple, as indicated by the above-mentioned per cell indication information. For example, cell A can support access to independently deployed non-public networks SNPN1 and SNPN2. If the first indication information is the above-mentioned per cell indication information, the access layer will also input the network identifier corresponding to the first indication information when inputting the first indication information to the non-access layer, that is, the network identifier corresponding to the SNPN 1 and SNPN2 networks. Or, if the first indication information is the above-mentioned per SNPN indication information, the access layer will also input the network identifier corresponding to the first indication information when inputting the first indication information to the non-access layer, such as the network identifier corresponding to the SNPN1 network.

[0060] The above-mentioned method of inputting the access control information and network identification information to the non-access stratum through the access stratum may specifically be:

[0061] 1) The UE AS inputs the access control indication information obtained from the cell and the independent non-public network identifier (such as SNPN ID) corresponding to the indication information to the UE NAS;

[0062] This method corresponds to the above-mentioned per SNPN indication information.

[0063] 2) The UE AS inputs the access control indication information obtained from the cell and all independently deployed non-public network identifiers (such as SNPN ID) corresponding to the cell to the UE NAS;

[0064] This method corresponds to the above-mentioned per cell indication information.

[0065] Optionally, when the network identification information is used to identify the target network mode corresponding to the access control information, when initiating emergency services through the non-access layer, the method of the embodiment of the present application may further include: when the access control information indicates that the terminal working in the target network mode is allowed to obtain emergency services, and the network mode of the terminal matches the target network mode, and the network selected or registered by the terminal does not match the target network identified by the network identification information, selecting the target network identified by the network identification information through the non-access layer.

[0066] In the case where the access control information is per SNPN indication information, the above-mentioned method of initiating emergency services through the non-access layer can be further described in a specific application scenario as follows: if the acquired access control indication information indicates that the cell supports UEs in SNPN mode to obtain emergency services (the indication information corresponds to the independently deployed non-public network SNPN1), and the selected SNPN or registered SNPN of the UE in SNPN mode (such as the selected SNPN or registered SNPN of the UE is SNPN2) does not match the independently deployed SNPN (such as SNPN1) corresponding to the access control indication information, then the UE NAS layer performs SNPN selection. For example, based on the acquired access control indication information, the UE selects an independently deployed non-public network that supports UEs in SNPN mode to obtain emergency services. Exemplarily, the UE NAS performs the SNPN selection process and selects the independently deployed non-public network SNPN1.

[0067] Optionally, when the network identification information is used to identify all target network modes corresponding to the cell, when emergency services are initiated through the non-access layer, the method of the embodiment of the present application may further include: when the access control information indicates that the terminal operating in the first target network mode is not allowed to obtain emergency services, and the network mode of the terminal matches the first target network mode, and the network selected or registered by the terminal matches the first target network identified by the network identification information, selecting a second target network through the non-access layer, wherein the access control information corresponding to the second target network mode indicates that the terminal operating in the first target network mode is allowed to obtain emergency services.

[0068] In the case where the access control information is per SNPN indication information, the above-mentioned method of initiating emergency services through the non-access layer can be further described in a specific application scenario as follows: if the obtained access control indication information indicates that the cell does not support UE in SNPN1 mode to obtain emergency services, and the selected SNPN of the UE in SNPN1 mode matches the independently deployed SNPN1 corresponding to the access control indication information, the UE NAS layer performs SNPN selection; for example, the selected SNPN of the UE in SNPN mode is SNPN1, and the obtained indication information indicates that SNPN1 does not support the provision of emergency services, then the UE performs SNPN selection. Exemplarily, the UE selects an independently deployed non-public network that supports UEs in SNPN mode to obtain emergency services based on the obtained access control indication information; for example, if the access control indication information obtained by the UE indicates that SNPN2 can provide emergency services, then the UE NAS selects SNPN2.

[0069] Through the control method for obtaining emergency services provided in this application, the target type of terminal (such as UE in SNPN mode) can determine whether the target type of terminal is supported to obtain emergency services from the cell based on the access control information provided by the network side, so as to avoid unnecessary attempts that result in failure to obtain emergency services in a timely manner.

[0070] It should be noted that the control method for obtaining emergency services provided in the embodiments of the present application can be executed by a control device for obtaining emergency services, or by a module in the control device for obtaining emergency services that is used to execute the control method for obtaining emergency services.
