Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communications, and more particularly, to a wireless communication method and device. BACKGROUND

[0002] New Radio (NR) Release 16 (R16) introduces Non-public Network (NPN), in order to increase the flexibility of NPN deployment, NPN network can be further divided into Stand-alone Non-public Networks (SNPN) and Closed Access Group (CAG) network, a SNPN is determined by a Public Land Mobile Network (PLMN) Identifier (ID) and a Network Identifier (NID), and a CAG network is determined by a PLMN ID and a CAG Identifier (CAG ID).

[0003] Generally, it is necessary to rely on an operator to provide an NPN, but for the network deployment demand of a temporary NPN, such as for the deployment of a temporary NPN for temporary concert communication or temporary emergency communication, it is not an efficient network building mode to rely on an operator to provide a temporary NPN each time. Therefore, it seems more efficient for an operator to allow a third party to build its own network through a protocol authorization. These NPN networks deployed by the third party have new network features, and the network side usually uses system broadcast information to notify the terminal device of the new network feature information. Only the terminal device that meets the constraint conditions corresponding to the new network feature information can access the NPN network deployed by the third party.

[0004] In the terminal mobility control process, for example, the mobility of a terminal device causes the handover of an access network device, and the source access network device needs to determine whether it can be handed over to a target access network device. In the current handover decision process, since the source access network device does not obtain the configuration information of whether the terminal device supports the third-party NPN network, it is impossible to hand over to the target access network device corresponding to the third-party NPN network, that is, it is impossible to select a suitable target cell for the terminal device.

[0027] The technical solutions in the embodiments of the present application will be described below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. All other embodiments obtained by those of ordinary skill in the art without creative labor on the basis of the embodiments in the present application also belong to the scope of protection of the present application.

[0028] Figure 1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0029] As Figure 1As shown, the communication system 100 can include a terminal device 110 and an access network device 120. The access network device 120 can communicate with the terminal device 110 over the air interface. The terminal device 110 and the access network device 120 support multi-service transmission.

[0030] It should be understood that the embodiments of the present application are only exemplarily described with the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, for example: a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), a 5G communication system (also referred to as a New Radio (NR) communication system), or a future communication system, etc.

[0031] Taking the 5G communication system as an example, the main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable and low latency communication (URLLC), and massive machine type of communication (mMTC). The eMBB still aims to enable users to obtain multimedia content, services and data, and its demand is growing rapidly. Since the eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., the differences in its capabilities and requirements are relatively large, so it cannot be generalized and must be analyzed in detail in combination with the specific deployment scenario. The typical applications of URLLC include: industrial automation, power automation, remote medical operation (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive service, low-cost module and long service life, etc.

[0032] In a 5G network environment, in order to reduce air interface signaling and quickly recover wireless connection, a new radio resource control (RRC) state, RRC_INACTIVE state, is defined for the purpose of quickly recovering data services. This state is different from RRC_IDLE and RRC_CONNECTED states. RRC_IDLE: mobility is based on terminal device cell selection reselection, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal device access stratum (AS) context on the access network device side, nor is there an RRC connection. RRC_CONNECTED: there is an RRC connection, and the access network device and the terminal device have a UE AS context; the access network device knows the location of the terminal device is at the specific cell level. Mobility is access network device controlled mobility. Terminal device and access network device can transmit unicast data. RRC_INACTIVE: mobility is based on terminal device cell selection reselection, there is a connection between CN and NR, terminal device AS context exists on a certain access network device, paging is triggered by the radio access network (RAN), RAN-based paging area is managed by the RAN, and the access network device knows the location of the terminal device is based on the RAN-based paging area level.

[0033] In Figure 1 In the communication system 100 shown, the access network device 120 can be an access network device that communicates with the terminal device 110. The access network device can provide communication coverage for a specific geographic area and can communicate with the terminal device 110 (e.g., UE) located within the coverage area.

[0034] The access network device 120 can be an evolved node B (eNB or eNodeB) in a long term evolution (LTE) system, or a next generation radio access network (NG RAN) device, or a base station (gNB) in an NR system, or a radio controller in a cloud radio access network (CRAN), or a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a future evolved access network device in a public land mobile network (PLMN), etc.

[0035] The terminal device 110 can be any terminal device, including but not limited to a terminal device that uses a wired or wireless connection with the access network device 120 or other terminal devices.

[0036] For example, the terminal device 110 can refer to an access terminal, a user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal can be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having wireless communication functions, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved network, etc.

[0037] The terminal device 110 can be used for Device to Device (D2D) communication.

[0038] The wireless communication system 100 can further include a core network device 130 in communication with the base station, which can be a 5G core network (5GC) device, for example, an Access and Mobility Management Function (AMF), for another example, an Authentication Server Function (AUSF), for another example, a User Plane Function (UPF), for another example, a Session Management Function (SMF). Alternatively, the core network device 130 can also be an Evolved Packet Core (EPC) device of an LTE network, for example, a Session Management Function + Core Packet Gateway (SMF + PGW-C) device. It should be understood that the SMF + PGW-C can simultaneously implement the functions that can be implemented by the SMF and the PGW-C. In the process of network evolution, the above-mentioned core network device can also be called other names, or new network entities can be formed by dividing the functions of the core network, which is not limited by the embodiments of the present application.

[0039] The various functional units in the communication system 100 can also establish a connection through a next generation (NG) interface to realize communication.

[0040] For example, a terminal device establishes an air interface connection with an access network device through an NR interface, for transmission of user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with an AMF through an NG interface 1 (N1 for short); an access network device, such as a next generation wireless access base station (gNB), can establish a user plane data connection with a UPF through an NG interface 3 (N3 for short); the access network device can establish a control plane signaling connection with the AMF through an NG interface 2 (N2 for short); the UPF can establish a control plane signaling connection with an SMF through an NG interface 4 (N4 for short); the UPF can exchange user plane data with a data network through an NG interface 6 (N6 for short); the AMF can establish a control plane signaling connection with the SMF through an NG interface 11 (N11 for short); the SMF can establish a control plane signaling connection with a PCF through an NG interface 7 (N7 for short).

[0041] Figure 1 An access network device, a core network device, and two terminal devices are exemplarily shown. Optionally, the wireless communication system 100 can include multiple access network devices, and each access network device can include other numbers of terminal devices within its coverage, which is not limited in the embodiments of the present application.

[0042] It should be understood that the devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices. For example, Figure 1 For example, the communication system 100, the communication devices can include an access network device 120 and a terminal device 110 with communication functions, and the access network device 120 and the terminal device 110 can be the devices described above, which will not be described herein again; the communication devices can also include other devices in the communication system 100, such as a network controller, a mobile management entity, and other network entities, which are not limited in the embodiments of the present application.

[0043] It should be understood that the terms “system” and “network” are often used interchangeably herein.

[0044] The introduction of NPN by NR R16 increases the flexibility of NPN deployment. NPN can be further divided into SNPN and CAG network. An SNPN is determined by a PLMN ID and an NID, and a CAG network is determined by a PLMN ID and a CAG ID. Taking an SNPN as an example, a PLMN ID and an NID can be used as the identifier of an SNPN. A user subscribed to a certain SNPN service will be configured with a corresponding subscriber permanent identifier (SUPI) and subscription information, which are stored in the terminal device and the core network side. A user subscribed to an SNPN service needs to support an SNPN access mode. A user configured in the SNPN access mode can only access the network through the SNPN. A user not configured in the SNPN access mode can perform a PLMN selection process. The configuration mode (activation, deactivation, etc.) of the SNPN access mode is implemented by the terminal device. In the initial access and cell reselection process, the access network device needs to broadcast the NID and the corresponding PLMN ID information supported by itself. A user configured in the SNPN access mode can select an accessible SNPN cell according to his own subscription information, and the core network device can also authenticate the identity of the user according to the subscription information of the user.

[0045] A PLMN can support any network sharing combination mode of the general public network, SNPN and CAG network at the same time. For example, a PLMN can support a general public network, an SNPN or a CAG network alone, or support a network sharing combination mode of a general public network and an SNPN, or even support a network sharing combination mode of a general public network, an SNPN and a CAG network. In other words, a general public network, an SNPN or a CAG network can be supported by a PLMN, or a general public network and an SNPN can share a PLMN network at the same time, or even a general public network, an SNPN and a CAG network can share a PLMN network at the same time. The logical deployment relationship between the general public network, the SNPN and the CAG network can be more clearly reflected by Table 1.

[0047]

[0048]

[0049] As shown in Table 1, from the network configuration point of view, one cell can be configured with both common network PLMN ID list information and non-public network NPN network identification list information at the same time. The non-public network NPN network identification list information is an optional parameter introduced by NR R16. For CAG type NPN networks, one PLMN ID is allowed to be associated with a CAG ID list. For SNPN type NPN networks, one PLMN ID is allowed to be associated with an NID list.

[0050] The parameters N, M, and W in Table 1 are all positive integers greater than or equal to 1.

[0051] Figure 2 is a schematic diagram of the networking combination relationship between the general public network, SNPN, and CAG network provided by the embodiments of the present application.

[0052] As shown in Table 1, from the network configuration point of view, one cell can be configured with both common network PLMN ID list information and non-public network NPN network identification list information at the same time. The non-public network NPN network identification list information is an optional parameter introduced by NR R16. For CAG type NPN networks, one PLMN ID is allowed to be associated with a CAG ID list. For SNPN type NPN networks, one PLMN ID is allowed to be associated with an NID list. Figure 2 As shown in Table 1, from the network configuration point of view, one cell can be configured with both common network PLMN ID list information and non-public network NPN network identification list information at the same time. The non-public network NPN network identification list information is an optional parameter introduced by NR R16. For CAG type NPN networks, one PLMN ID is allowed to be associated with a CAG ID list. For SNPN type NPN networks, one PLMN ID is allowed to be associated with an NID list.

[0053] The traditional cell handover or access network device handover process in a cellular system is as follows:

[0054] Figure 3 is a flowchart of the cell handover or access network device handover process in a cellular system provided by the embodiments of the present application, as shown in Figure 3 The process includes the following steps:

[0055] S310: After receiving the measurement configuration of the source access network device, the terminal device starts the corresponding measurement process when the measurement condition is met.

[0056] S320: The terminal device reports the measured result to the source access network device when the measurement result reporting condition is met.

[0057] S330: After receiving the measurement report sent by the terminal device, the source access network device makes a handover decision in combination with the local rules.

[0058] S340: If the source access network device determines that the cell handover can be performed, the source access network device sends a handover request to the target access network device.

[0059] S350: After receiving the handover request sent by the source access network device, the target access network device determines whether to accept the handover request according to local load information and the like.

[0060] S360: If the target access network device determines that the handover request can be accepted, the target access network device sends a handover command to the source access network device.

[0061] S370: After receiving the handover command sent by the target access network device, the source cell forwards the handover command to the terminal device in a transparent manner.

[0062] S380: After receiving the handover command, the terminal device stores configuration information in the handover command.

[0063] S390: The terminal device accesses the target access network device according to the configuration information in the handover command.

[0064] As described above, in the current handover decision process, the source access network device does not obtain the configuration information of whether the terminal device supports the third-party NPN network, so that the terminal device cannot be switched to the target access network device corresponding to the third-party NPN network, that is, the terminal device cannot be selected to the appropriate target cell.

[0065] To solve the above technical problems, the present application provides a wireless communication method and device. Wherein, the source access network device can obtain the configuration information of whether the terminal device supports the third-party NPN network, based on this, the source access network device can consider the target access network device corresponding to the third-party NPN network when performing the handover of the access network device, so as to select the appropriate target cell for the terminal device.

[0066] The technical scheme of the present application will be described in detail below:

[0067] Figure 4 is an interaction flowchart of a wireless communication method provided by an embodiment of the present application, wherein the execution subject involved in the method is a first access network device and a second access network device, or the execution subject involved in the method is a first access network device and a core network device, as shown in Figure 4 The method comprises:

[0068] S410: The second access network device or the core network device sends a first message to the first access network device, and the first message comprises terminal-granularity NPN constraint configuration information.

[0069] The NPN constraint configuration information is used to assist the terminal mobility control process on the access network side.

[0070] It should be understood that the terminal mobility control procedure can involve handover between access network devices, i.e. cell handover.

[0071] Optionally, the NPN constraint configuration information comprises: third-party NPN constraint configuration information, and / or, operator NPN constraint configuration information.

[0072] It should be understood that the third-party NPN constraint configuration information is also referred to as constraint configuration information of a third-party NPN, or referred to as constraint configuration information about a third-party NPN. The operator NPN constraint configuration information is also referred to as constraint configuration information of an operator NPN, or referred to as constraint configuration information about an operator NPN.

[0073] For example, the NPN constraint configuration information comprises: constraint configuration information of third-party NPN1, 2, wherein 1, 2 respectively represent the identity of a third-party NPN. Or, the NPN constraint configuration information comprises: constraint configuration information of operator NPN3, 4, wherein 3, 4 respectively represent the identity of an operator NPN. Or, the NPN constraint configuration information comprises: constraint configuration information of third-party NPN1, 2 and constraint configuration information of operator NPN3, 4.

[0074] Optionally, the second access network device obtains the terminal-granularity NPN constraint configuration information from the core network device, and sends the terminal-granularity NPN constraint configuration information to the first access network device.

[0075] Optionally, the terminal-granularity NPN constraint configuration information, i.e. the NPN constraint configuration information, is for a terminal device, and the terminal device is not a specific terminal device.

[0076] Optionally, the first access network device can be an operator's own access network device, or an operator-authorized third-party access network device, and the present application does not limit this.

[0077] Optionally, the first access network device receives the first message sent by the second access network device or the core network device in a context establishment or modification or update or re-establishment or transfer procedure of the terminal device.

[0078] Optionally, if the first access network device receives the first message sent by the core network device in a context establishment procedure of the terminal device, the first message can be an initial context establishment request.

[0079] Optionally, after the first access network device obtains the NPN constraint configuration information, the first access network device can perform a terminal mobility control procedure, such as a cell or access network device handover judgment procedure, according to the NPN constraint configuration information.

[0080] In summary, in the present application, the first access network device can obtain the NPN constraint configuration information of terminal granularity. Based on this, when performing access network device switching, the first access network device can consider the target access network device corresponding to the NPN network, such as the third-party NPN network, so as to select a suitable target cell for the terminal device.

[0081] Optionally, the NPN constraint configuration information includes at least one of the following, but is not limited thereto:

[0082] Constraint configuration information 1, NPN network identification list configuration information allowed or prohibited to access by the terminal device.

[0083] Constraint configuration information 2, first group identification list configuration information allowed or prohibited to access by the terminal device, the first group identification list configuration information is used for the terminal device to perform authentication through the NPN network.

[0084] Constraint configuration information 3, second group identification list configuration information allowed or prohibited to access by the terminal device, the second group identification list configuration information is used for the terminal device to obtain or update its own subscription data through the NPN network.

[0085] Constraint configuration information 4, mobility control priority configuration information between the PLMN and the NPN.

[0086] Constraint configuration information 5, limit access information associated with the NPN network identification list configuration information.

[0087] It should be understood that the NPN network identification list configuration information allowed or prohibited to access by the terminal device includes NPN network identification allowed or prohibited to access by the terminal device. As described above, the NPN network identification included in the NPN network identification list configuration information can be the identification of the third-party NPN network, can also be the identification of the operator NPN network, and can also include the identification of the third-party NPN network and the identification of the operator NPN network.

[0088] Optionally, the NPN network identification list configuration information is at least one of the following, but is not limited thereto:

[0089] PLMN network identification list configuration information.

[0090] SNPN network identification list configuration information.

[0091] CAG network identification list configuration information.

[0092] Temporary network identification list configuration information.

[0093] Access control related network identification list configuration information.

[0094] It should be understood that the access control related network identity is similar to the PLMN network identity or the SNPN network identity or the CAG network identity, i.e. the same in practical meaning, but the length of the access control related network identity can be different from the PLMN network identity or the SNPN network identity or the CAG network identity. Similarly, the temporary network identity is similar to the PLMN network identity or the SNPN network identity or the CAG network identity, i.e. the same in practical meaning, but it is a temporary identity of the PLMN or the SNPN or the CAG.

[0095] It should be understood that the first group identity list configuration information includes at least one group identity, and each group identity is used for the terminal device to perform authentication through the corresponding NPN network. Wherein, the corresponding NPN network here can be an operator NPN network, or a third-party NPN network, i.e. the terminal device can perform an authentication process in an operator NPN network, or initiate an authentication process in an operator-authorized third-party NPN.

[0096] It should be understood that the second group identity list configuration information includes at least one group identity, and each group identity is used for the terminal device to obtain its subscription data through the corresponding NPN network.

[0097] It should be understood that if the NPN constraint configuration information is third-party NPN constraint configuration information, the mobility control priority configuration information between the PLMN and the NPN refers to the mobility control priority configuration information between the PLMN and the third-party NPN. In this case, the NPN constraint configuration information can further include: mobility control priority configuration information between the operator NPN and the third-party NPN. If the NPN constraint configuration information is operator NPN constraint configuration information, the mobility control priority configuration information between the PLMN and the NPN refers to the mobility control priority configuration information between the PLMN and the operator NPN. If the NPN constraint configuration information is operator NPN constraint configuration information and third-party NPN constraint configuration information, the mobility control priority configuration information between the PLMN and the NPN refers to the mobility control priority configuration information between the PLMN and the operator NPN, and the mobility control priority configuration information between the PLMN and the third-party NPN. In this case, the NPN constraint configuration information can further include: mobility control priority configuration information between the operator NPN and the third-party NPN. In summary, when the NPN constraint configuration information includes third-party NPN constraint configuration information, the NPN constraint configuration information further includes: mobility control priority configuration information between the operator NPN and the third-party NPN.

[0098] It should be understood that the mobility control priority configuration information is also referred to as priority configuration information in the terminal mobility control process, or also referred to as mobility control related priority configuration information, that is, priority configuration information between the PLMN and the NPN in the terminal mobility control process.

[0099] It is worth mentioning that the mobility control priority configuration information between the PLMN and the NPN, and the mobility control priority configuration information between the operator NPN and the third-party NPN can be configured based on network type granularity or network identity granularity. For example, the priority of the third-party NPN is higher than the priority of the PLMN, which is priority configuration information configured based on network type granularity. While the priority of the third-party NPN1 is higher than the priority of the PLMN2, 1 and 2 respectively represent network identities, which is priority configuration information configured based on network identity granularity.

[0100] Optionally, the mobility control priority configuration information between the PLMN and the NPN, and / or the mobility control priority configuration information between the operator NPN and the third-party NPN is generated by the core network device or reported from the terminal device Non-Access Stratum (NAS) process.

[0101] Optionally, the access restriction information includes at least one of the following, but is not limited thereto:

[0102] Cell Global Identity (CGI) list configuration information.

[0103] Tracking Area Identity (TAI) list configuration information.

[0104] Radio Access Type (RAT) list configuration information.

[0105] Core network type list configuration information.

[0106] It should be understood that the CGI list configuration information included in the access restriction information is the CGI list configuration information that restricts the terminal device to only access or prohibits the terminal device from accessing. The TAI list configuration information included in the access restriction information is the TAI list configuration information that restricts the terminal device to only access or prohibits the terminal device from accessing. The RAT list configuration information included in the access restriction information is the RAT list configuration information that restricts the terminal device to only access or prohibits the terminal device from entering. The core network type list configuration information included in the access restriction information is the core network type list configuration information that restricts the terminal device to only access or prohibits the terminal device from accessing.

[0107] Optionally, any one of the NPN constraint configuration information other than the NPN network identification list configuration information includes any one of the following configuration granularity, i.e., the configuration granularity of the constraint configuration information 2-5 is any one of the following: terminal granularity, NPN network identification granularity.

[0108] Optionally, the NPN network identification granularity includes any one of the following:

[0109] PLMN network identification granularity.

[0110] SNPN network identification granularity.

[0111] CAG network identification granularity.

[0112] Temporary network identification granularity.

[0113] Access control related network identification granularity.

[0114] It is worth mentioning that when the configuration granularity of the constraint configuration information 2-5 is the terminal granularity, they are parallel configuration information with the constraint configuration information 1, as shown in Table 2 and Table 3:

[0115] Table 2: Configuration format of terminal granularity

[0116] Constraint configuration information 1 Constraint configuration information 2 Constraint configuration information 3 Constraint configuration information 4 Constraint configuration information 5

[0117] Optionally, the constraint configuration information 1-5 can be included in the context information of the terminal device. As shown in Table 3:

[0118] Table 3: Configuration format of terminal granularity
