[0014] The following clearly and completely describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art on the basis of the embodiments of the present application without any creative efforts are within the scope of protection of the present application.

[0015] The terms "first," "second," etc. in the specification and claims of the present application are intended to distinguish between similar objects and are not intended to describe a particular order or sequence. It is to be understood that data so used are interchangeable where appropriate, such that the embodiments of the present application may be performed in an order other than that shown 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, e.g., the first object may be one or more. Note that "and / or" in the specification and claims represents at least one of the objects connected, and the character " / " generally represents an "or" relationship between the related objects.

[0016] First, a pertinent introduction to the terminology used in this application is provided.

[0017] 1) non-public network (NPN), In industrial environments, many applications (such as production manufacturing, automation control, etc.) have very high performance demands, such as low latency, high reliability, etc. In local networks, as equipment density increases, these performance demands are difficult to meet, but the communication demands of vertical industries can be met by using wireless links instead of traditional wired links and providing LAN-type private communication services to these kinds of vertical industries through 5G communication networks.

[0018] At present, 3GPP agrees to adopt two types of non-public network (NPN) deployment modes to support communication applications in vertical industries. The first type is standalone NPN deployment (SNPN), which does not rely on a public network and can determine whether a user equipment (UE) can reside in a network by a non-public network identifier (e.g., SNPN ID) provided by the network side. For example, a traditional UE (e.g., a UE that does not support SNPN access) cannot reside normally in a cell corresponding to an SNPN network, but an SNPN UE cannot reside normally in a cell corresponding to a Public Land Mobile Network (PLMN) network. A UE with SNPN capability can operate in SNPN mode and can also operate in PLMN mode. When a UE operates in SNPN mode, it can only access the network through SNPN. When it operates in PLMN mode, it can only access the network through PLMN.

[0019] The second type is non-independent NPN deployment (Public Network Integrated NPN, PNI-NPN), which relies on the public network. In this deployment scenario, the Closed Access Group (CAG) concept is introduced to control the access of UE to a certain cell. For example, when the UE subscribes to the NPN service, it indicates the CAG to which the UE belongs, and the cell provides the CAG identifier it supports, so that the UE can determine whether it can access a cell. For example, 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 it can access the cell. If the access group supported by a cell is only CAG2, the UE can determine that it cannot access the cell.

[0020] 2) RAN sharing, Radio Access Network (RAN) sharing refers to multiple operators sharing the same radio access network. In a non-public network deployment scenario, a non-public network (e.g., a network identified by an SNPN ID) and a public network (e.g., a network identified by a PLMN ID) can share one radio access network. In NR, up to 12 network sharing (e.g., a network identified by a PLMN ID and / or a network identified by an SNPN ID and / or a network identified by a PLMN ID+CAG ID) can be supported.

[0021] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to 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 always used interchangeably, and the techniques described may be used in the above-mentioned systems and radio technologies, or in other systems and radio technologies. However, although the following description describes New Radio (NR) systems for illustrative purposes and uses NR terminology in most of the following description, these technologies may also be used in applications other than NR system applications, such as sixth generation (6G) systems. th This may be applied to a 6G (6th Generation) communication system.

[0022] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer (or called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11.The network side equipment 12 may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an 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 receiving point (TRP), or any other suitable term in the art, and as long as the same technical effect is achieved, the base station is not limited to a specific technical term, and it should be explained that in the embodiments of this application, only a base station in an NR system is taken as an example, but the specific type of the base station is not limited.

[0023] The following describes in detail the control method for obtaining emergency services according to the embodiment of the present application through specific embodiments and its application scenarios in conjunction with the drawings.

[0024] FIG. 2 is a flow chart of a control method for obtaining emergency services in an embodiment of the present application, which is used in a terminal. As shown in FIG. 2, the steps of the method include: a step S202 of obtaining access control information provided by a cell, the access control information being used to indicate whether or not to allow a terminal operating in a target network mode to obtain emergency services; 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, the step S204 includes determining the cell as a cell in which emergency services can be obtained.

[0025] As can be seen from the above steps S202 and S204, if the target network mode indicated by the access control information provided by the cell matches the network mode in which the terminal itself operates, and the access control information indicates that the terminal operating in the target network mode is allowed to obtain emergency services, the terminal can determine the cell as a cell from which 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, thereby avoiding unnecessary attempts by the terminal, and solving the problem in the prior art that the terminal cannot timely obtain emergency services because the terminal cannot distinguish which network provides emergency services.

[0026] Optionally, in another optional embodiment 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 as a cell from which emergency services cannot be obtained, that is, the terminal can determine whether emergency services can be initiated in the cell based on the access control information.

[0027] Further, in an embodiment of the present application, if the terminal's current network mode 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.

[0028] 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 limited service state.

[0029] Alternatively, the target network mode in the embodiment of the present application may include a standalone non-public network SNPN mode and a public land mobile network PLMN mode. In addition, 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, while 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. As can be understood, the SNPN capability of a terminal is equivalent to the SNPN access capability, and the CAG capability is equivalent to the CAG access capability.

[0030] It should be noted that a terminal that does not have the SNPN and CAG capabilities is a conventional terminal.

[0031] Optionally, the cell types in the embodiments of the present application include at least one of the following:

[0032] 1) A cell that supports PLMN and SNPN access, i.e., a cell that can provide PLMN and SNPN access, e.g., a cell that can provide one or more public network accesses (wherein the public network is identified by a PLMN ID) and one or more independently deployed non-public network accesses (wherein the independently deployed non-public network is identified by a SNPN ID).

[0033] 2) Cells supporting SNPN, PLMN and closed access group (CAG) access, i.e., cells capable of providing SNPN, PLMN and CAG access, e.g., cells capable of providing one or more public network accesses (identified by a PLMN ID), one or more independently deployed non-public network accesses (identified by a SNPN ID) and one or more non-public network accesses that are not independently deployed (identified by a PLMN ID+CAG ID).

[0034] 3) A cell supporting SNPN and CAG access, i.e., a cell capable of providing SNPN and CAG access, e.g., a cell capable of providing one or more independently deployed non-public network accesses (identified by SNPN ID) and one or more non-public network accesses that are not independently deployed (identified by PLMN ID+CAG ID).

[0035] 4) A cell that supports SNPN access, ie, a cell that can provide SNPN access, for example, a cell that can provide one or more non-public network accesses (identified by an SNPN ID).

[0036] Optionally, the access control information in the embodiment of the present application includes at least one of first instruction information and second instruction information, where the first instruction information is used to indicate whether or not to allow a terminal operating in SNPN mode to obtain emergency services, and the second instruction information is used to indicate whether or not to allow a terminal operating in PLMN mode to obtain emergency services.

[0037] In the following, the first instruction information will be described as an example.

[0038] The first indication information may be per cell indication information, for example, per cell indication information (e.g., one-bit indication information) is carried in SIB1, and if the value of the indication information is "1", it indicates that the UE operating in SNPN mode supports obtaining emergency services from this cell, and if the value is "0", it indicates that the UE in SNPN mode does not support obtaining emergency services from this cell. Or, if per cell indication information (e.g., one-bit indication information) exists or is carried in SIB1, it indicates that the UE in SNPN mode supports obtaining emergency services from this cell, and if per cell indication information (e.g., one-bit indication information) does not exist or is not carried in SIB1, it indicates that the UE in SNPN mode does not support obtaining emergency services from this cell. Exemplarily, if the first indication information is per cell indication information, if all independently deployed non-public networks sharing this cell cannot provide emergency services, the network side sets the first indication information to not support obtaining emergency services by the UE in SNPN mode, otherwise, sets the first indication information to support obtaining emergency services by the UE in SNPN mode. 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), but if neither SNPN1 nor SNPN2 supports providing emergency services, the network sets the first indication information to not support the UE in SNPN mode from obtaining emergency services, for example, if the first indication information is a one-bit indication, the network sets the one bit to be "0" or the first indication information is not carried; or The first indication information may also be per SNPN indication information, such as one-bit indication information or bit diagram, where each bit in the bit diagram corresponds to an independently deployed non-public network, in a specific application scenario, for example, cell 1 supports two independently deployed non-public network accesses, SNPN1 and SNPN2, and there is one indication information for each independently deployed non-public network (for example, SNPN1), and when the value of the indication information is "1", it indicates that the corresponding independently deployed non-public network (for example, SNPN 1) can provide emergency service, and the UE in SNPN mode can obtain emergency service through this independently deployed non-public network. When the value of the indication information is "0", it indicates that the corresponding independently deployed non-public network (for example, SNPN 1) does not provide emergency service, and the UE in SNPN mode cannot obtain emergency service through this independently deployed non-public network. Alternatively, if the network side provides per SNPN indication information (e.g., one-bit indication information) (e.g., the indication information exists in SIB1), it indicates that the corresponding independently deployed non-public network (e.g., SNPN 1) can provide emergency services and the UE in SNPN mode can obtain emergency services through this independently deployed non-public network; if the network side does not provide per SNPN indication information (e.g., one-bit indication information) (e.g., the indication information does not exist in SIB1), it indicates that the corresponding independently deployed non-public network (e.g., SNPN 1) does not provide emergency services and the UE in SNPN mode cannot obtain emergency services from this independently deployed non-public network.

[0039] For the second indication information, in a specific application scenario, bit information can be used to indicate whether emergency services can be obtained, and the manner in which this is done is similar to that of the first indication information, and will not be described further here.

[0040] According to the first indication information, in the embodiment of the present application, a manner in which the terminal can determine whether the terminal can initiate an emergency service in a cell according to the first indication information may be as follows: 1) If the acquired access control indication information indicates that the cell supports the acquisition of emergency services by an SNPN mode UE, and the UE is an SNPN mode UE (e.g., a UE in a restricted service mode), the UE determines that it can obtain emergency services from this cell; for example, if the network side provides per cell indication information (e.g., indication information is carried in SIB1) and the indication information indicates that this cell supports providing emergency services to an SNPN mode UE, the SNPN mode UE determines that it can obtain emergency services from this cell; or, if the network side provides per SNPN indication information (e.g., indication information exists in SIB1) and at least one indication information indicates that a corresponding independently deployed non-public network supports the provision of emergency services, the SNPN mode UE determines that it can obtain emergency services from this cell.

[0041] 2) If the obtained access control indication information only indicates that the cell supports the acquisition of emergency services by a UE in SNPN mode, then if the UE is a UE in PLMN mode, the UE (e.g., a UE in restricted service mode) determines that it cannot obtain emergency services from this cell.

[0042] 3) If the obtained access control indication information only indicates that the cell supports acquisition of emergency services by a UE in PLMN mode, then if the UE is a UE in SNPN mode (e.g., a UE in restricted service mode), the UE determines that it cannot obtain emergency services from this cell.

[0043] Optionally, the method steps of the embodiment of the present application may further include: determining a cell capable of obtaining emergency services as a candidate cell for cell selection or reselection 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. Furthermore, the cell capable of obtaining emergency services may be determined as a top candidate cell for cell selection or reselection, i.e., when there are multiple candidate cells (e.g., including a cell capable of obtaining emergency services and a cell not capable of obtaining emergency services), the cell capable of obtaining emergency services may be preferentially selected as a candidate cell for cell selection or reselection.

[0044] Optionally, in the embodiment of the present application, the manner 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 stratum.

[0045] Therefore, after obtaining the access control information provided by the cell by the access stratum, the method of the embodiment of the present application may further include: inputting the access control information to a non-access stratum by the access stratum.

[0046] Therefore, after obtaining the access control information provided by the cell by the access stratum, the method of the embodiment of the present application may further include inputting network identifier information by the access stratum to the non-access stratum, where the network identifier information is used to identify a target network corresponding to the access control information.

[0047] It should be noted that the network identifier indicated by the network identifier information may be one, for example, as indicated by the per SNPN indication information, and the network identifier indicated by the network identifier information may be multiple, for example, as indicated by the per cell indication information. Exemplarily, cell A can support independently deployed non-public network SNPN1 and SNPN2 access, and if the first indication information is the per cell indication information, the access stratum further inputs a network identifier corresponding to the first indication information, i.e., a network identifier corresponding to the SNPN1 and SNPN2 networks, when inputting the first indication information to the non-access stratum. Or, if the first indication information is the per SNPN indication information, the access stratum further inputs a network identifier corresponding to the first indication information, for example, a network identifier corresponding to the SNPN1 network, when inputting the first indication information to the non-access stratum.

[0048] Specifically, the above method of inputting access control information and network identifier information to the non-access stratum by the access stratum may be as follows.

[0049] 1) The UE AS inputs the access control indication information obtained from the cell and an independently deployed non-public network identifier (e.g., SNPN ID) corresponding to the indication information into the UE NAS; Here, this method corresponds to the above-mentioned per SNPN indication information.

[0050] 2) The UE AS inputs the access control indication information obtained from the cell and all independently deployed non-public network identifiers (e.g., SNPN IDs) corresponding to the cell to the UE NAS; Here, this method corresponds to the per cell instruction information.

[0051] Optionally, when the network identifier information is used to identify a target network mode corresponding to the access control information, when initiating emergency services by a non-access stratum, the method of an embodiment of the present application may further include selecting a target network identified by the network identifier information by the non-access stratum when the access control information indicates that the terminal operating 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 identifier information.

[0052] When the access control information is per SNPN indication information, the above manner of initiating emergency services by the non-access stratum may further be that, in a specific application scenario, when the acquired access control indication information indicates that a cell supports the UE in SNPN mode to obtain emergency services (this indication information corresponds to an independently deployed non-public network SNPN1), and the SNPN selected or registered by the UE in SNPN mode (for example, the SNPN selected or registered by the UE is SNPN2) does not match the independently deployed SNPN (for example, SNPN1) corresponding to the access control indication information, the UE NAS layer performs SNPN selection. For example, the UE selects an independently deployed non-public network that supports the UE in SNPN mode to obtain emergency services according to the acquired access control indication information. Illustratively, the UE NAS performs an SNPN selection process and selects an independently deployed non-public network SNPN1.

[0053] Optionally, when the network identifier information is used to identify all target network modes corresponding to a cell, when initiating emergency services through a non-access stratum, the method of the embodiment of the present application may further include selecting a second target network through the non-access stratum if 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 identifier information, where 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.

[0054] When the access control information is per SNPN indication information, the above manner of initiating emergency service by non-access stratum may further be that, in a specific application scenario, when the acquired access control indication information indicates that the cell does not support the UE in SNPN1 mode to obtain emergency service, and the SNPN selected by 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, when the SNPN selected by the UE in SNPN mode is SNPN1, and the acquired indication information indicates that SNPN1 does not support providing emergency service, the UE performs SNPN selection. Exemplarily, the UE selects an independently deployed non-public network that supports the UE in SNPN mode to obtain emergency service according to the acquired access control indication information, for example, when the access control indication information acquired by the UE indicates that SNPN2 can provide emergency service, the UE NAS selects SNPN2.

[0055] According to the control method for acquiring emergency services of the present application, it is possible to prevent unnecessary attempts to acquire emergency services in a timely manner by determining whether a target type terminal (e.g., a UE in SNPN mode) is supported to acquire emergency services from this cell based on access control information provided by the network side.

[0056] It should be noted that in the control method for obtaining emergency services according to the embodiment of the present application, the execution body may be a control device for obtaining emergency services, or a module for executing the control method for obtaining emergency services in the control device for obtaining emergency services. In the embodiment of the present application, the control device for obtaining emergency services according to the embodiment of the present application is described by taking the execution of the control method for obtaining emergency services by the control device for obtaining emergency services as an example.

[0065] Optionally, the apparatus in an embodiment of the present application may further include a second input module for inputting network identifier information to the non-access stratum by the access stratum, where the network identifier information is used to identify a target network corresponding to the access control information.
