Description

Wireless communication method, terminal device and network device

Technical Field

The embodiment of the application relates to the field of communication, and more particularly relates to a wireless communication method, terminal equipment and network equipment.

Background

The New air interface (New Radio, NR) 16 version (R16) introduces a Non-public Network (NPN), and in order to increase flexibility of NPN deployment, the NPN Network may be further divided into a Stand-alone Non-public Network (SNPN) and a closed access group (Closed Access Group, CAG) Network, where a SNPN is determined by public land mobile Network (Public Land Mobile Network, PLMN) Identifier (ID) Network identifier (Network Identifier, NID), and a CAG Network is determined by PLMN ID and CAG identifier (CAG ID).

Generally, it is necessary to rely on an operator to provide the NPN, but deploying the temporary NPN for temporary NPN network requirements, such as for temporary concert communication or temporary emergency communication, each time relying on an operator to provide the temporary NPN is not an efficient networking mode, based on which it seems more efficient for an operator to allow a third party to establish his own network by means of protocol authorization.

However, once the operator authorizes to allow the third party to establish own temporary NPN, the newly deployed cell can influence the neighbor relation of surrounding cells, and the network equipment is not utilized to maintain neighbor information. In addition, because the network is established by a third party, for surrounding cells of the newly deployed cell, an interface for directly interacting information is not necessarily provided between the existing neighbor cell and the newly deployed neighbor cell, and based on the interface, how to update neighbor cell information of the neighbor cell is a technical problem to be solved in the field.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that embodiments of the present application are illustrated by way of example only with respect to communication system 100, and embodiments of the present application are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), 5G communication system (also referred to as New Radio (NR) communication system), or future communication system, etc.

Taking a 5G communication system as an example, the main application scenarios of 5G are: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, eMBB), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (MASSIVE MACHINE TYPE of communications, mMTC). eMBB still aims at obtaining multimedia content, services and data by users, and the demand of which is growing very rapidly. Since eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., the capability and demand of which are also quite different, detailed analysis must be performed in conjunction with a specific deployment scenario, not to be generalized. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical features of mMTC include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

In a 5G network environment, for the purposes of reducing air interface signaling and quickly recovering a radio connection, and quickly recovering data traffic, a new radio resource control (Radio Resource Control, RRC) state, i.e., an rrc_inactive state, is defined. This state is different from the rrc_idle and rrc_connected states. Rrc_idle: mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and paging areas are configured by the CN. The base station side does not have a UE Access Stratum (AS) context, and does not have RRC connection. Rrc_connected: the RRC connection exists, and the base station and the UE exist a UE AS context; the network device knows that the location of the UE is cell specific. Mobility is mobility controlled by the network device. Unicast data may be transmitted between the UE and the base station. Rrc_inactive: mobility is a UE-based cell selection reselection, there is a connection between CN-NRs, the UE AS context is present on a certain base station, paging is triggered by the radio access network (Radio Access Network, RAN), the RAN-based paging area is managed by the RAN, the network device knows that the UE location is based on the RAN paging area level.

In the communication system 100 shown in fig. 1, the network device 120 may be an access network device in communication with the terminal device 110. The access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

The network device 120 may be an evolved base station (Evolutional Node B, eNB or eNodeB) in a long term evolution (Long Term Evolution, LTE) system, or a next generation radio access network (Next Generation Radio Access Network, NG RAN) device, or a base station (gNB) in a NR system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device 120 may be a relay station, an access point, a vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

Terminal device 110 may be any terminal device including, but not limited to, a terminal device that employs a wired or wireless connection with network device 120 or other terminal devices.

For example, the terminal device 110 may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a handheld device with wireless communication capabilities, 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 evolution network, etc.

The terminal Device 110 may be used for Device-to-Device (D2D) communication.

The wireless communication system 100 may further comprise a core network device 130 in communication with the base station, which core network device 130 may be a 5G core,5gc device, e.g. an access and mobility management function (ACCESS AND Mobility Management Function, AMF), further e.g. an authentication server function (Authentication Server Function, AUSF), further e.g. a user plane function (User Plane Function, UPF), further e.g. a session management function (Session Management Function, SMF). Optionally, the Core network device 130 may also be a packet Core evolution (Evolved Packet Core, EPC) device of the LTE network, for example, a session management function+a data gateway (Session Management Function +core PACKET GATEWAY, SMF +pgw-C) device of the Core network. It should be appreciated that SMF+PGW-C may perform the functions performed by both SMF and PGW-C. In the network evolution process, the core network device may also call other names, or form new network entities by dividing the functions of the core network, which is not limited in this embodiment of the present application.

Communication may also be achieved by establishing connections between various functional units in the communication system 100 through a next generation Network (NG) interface.

For example, the terminal device establishes an air interface connection with the access network device through an NR interface, and is used for transmitting user plane data and control plane signaling; the terminal equipment can establish control plane signaling connection with AMF through NG interface 1 (N1 for short); an access network device, such as a next generation radio 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 equipment can establish control plane signaling connection with AMF through NG interface 2 (N2 for short); the UPF can establish control plane signaling connection with the SMF through an NG interface 4 (N4 for short); the UPF can interact user plane data with the data network through an NG interface 6 (N6 for short); the AMF may establish a control plane signaling connection with the SMF through NG interface 11 (N11 for short); the SMF may establish a control plane signaling connection with the PCF via NG interface 7 (N7 for short).

Fig. 1 exemplarily illustrates one base station, one core network device, and two terminal devices, alternatively, the wireless communication system 100 may include a plurality of base station devices and each base station may include other number of terminal devices within a coverage area, which is not limited by the embodiment of the present application.

It should be understood that devices having communication functions in the network/system according to the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functions, where the network device 120 and the terminal device 110 may be the devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are used interchangeably herein.

The NR R16 introduces an NPN, which may be divided into SNPN and CAG networks in order to increase flexibility of NPN deployment, one SNPN is determined by PLMN ID and NID, and one CAG network is determined by PLMN ID and CAG identification (CAG ID). For example SNPN, PLMN ID and NID may be used as an identifier of SNPN, and a Subscriber subscribed to a certain SNPN service may configure a corresponding Subscriber permanent identifier (Subscriber PERMANENT IDENTIFIER, SUPI) and subscription information, and store them on the terminal device and the core network side. A user subscribed to SNPN needs to support SNPN access mode (SNPN ACCESS mode), and a user configured to SNPN access mode can only access the network through SNPN, and a user not configured to SNPN access mode can perform PLMN selection procedure. Wherein the SNPN access mode configuration (activation, deactivation, etc.) is implemented by the terminal device. In the initial access and cell reselection processes, the access network device needs to broadcast NID and corresponding PLMN ID information supported by itself, and the user configured with SNPN access mode can select an accessible SNPN cell according to own subscription information, and the core network device can also authenticate the identity of the user according to the subscription information of the user.

One PLMN may support any network sharing combination mode among the common public network, SNPN and CAG networks simultaneously. For example, one PLMN may support a common public network, SNPN, or CAG network alone, or may support a network sharing combination mode of the common public network and SNPN, or may support a network sharing combination mode of the common public network, SNPN, and CAG networks. In other words, the common public network, SNPN or CAG network may be supported by one PLMN, or the common public network and SNPN may share one PLMN network at the same time, or even the common public network, SNPN and CAG network may share one PLMN network at the same time. The following table 1 may be combined to more clearly reflect the logical deployment relationships among the common public network, SNPN, and CAG networks.

Table 1 network identification configuration schematic for a cell to support

As shown in table 1, from the network configuration perspective, one cell may simultaneously configure public network PLMN ID list information and non-public network NPN network identification list information, where the non-public network NPN network identification list information is an optional parameter introduced by NR R16, and for a CAG type NPN network, one PLMN ID is allowed to be associated with one CAG ID list; for SNPN types of NPN networks, one PLMN ID is allowed to be associated with one NID list.

The parameter N/M/W in Table 1 is a positive integer of 1 or more.

As shown in fig. 2, one physical cell may be shared by multiple PLMN networks at the same time, and each PLMN logical cell may constitute its own unique non-public network. Alternatively, different physical cells may be distinguished by physical cell identity (PHYSICAL CELL IDENTITIES, PCI). The number of physical cell identities of the NR system is 1008 in total. PCI is a radio signal used to distinguish between different cells, ensuring that there is no identical physical cell identity within the coverage of the relevant cell. Any network sharing combination of the common public network, SNPN and the CAG network can be freely deployed under one PLMN. Optionally, the number of independent SNPN subnetworks deployed in a physical cell, the number of independent CAG subnetworks, or the total number of SNPN and CAG subnetworks cannot exceed 12.

The terminal device may be in the cell where it normally resides. The network equipment can configure the frequency point priority information simultaneously when configuring a frequency point, the frequency point priority value is 0-7, 0 represents the lowest priority, 7 represents the highest priority, for the diversity of the frequency point priority configuration, the standard prescribes that each value of 0-7 can be associated with a decimal place value, the decimal place value range is {0.2,0.4,0.6,0.8}, and the whole digits and the decimal places are matched with 40 frequency point priority combinations in total. The frequency point priority can be configured through system information or special signaling, the frequency point priority of the special signaling is related to an effective duration, and the special frequency point priority always covers the public frequency point priority of the system information broadcast in the effective duration; after the effective duration is overtime, the terminal can only use the public frequency point priority.

In NPN, the terminal device may make cell selection based on cell selection reselection rules. For cell selection, if the cell selected by the terminal device meets the appropriate cell criteria, the terminal device may select to reside in the cell to complete cell selection. Aiming at cell reselection, if a reselected target cell meets a proper cell criterion and meets a reselection criterion condition defined based on absolute frequency point priority, the terminal equipment reselects to a cell which corresponds to the cell meeting the condition, and cell reselection is completed. The reselection criteria defined based on the absolute frequency point priority include the following three types:

A high priority frequency point reselection criterion;

The equal priority frequency point reselection criterion or the same frequency reselection criterion is also called as an R criterion; and

Low priority frequency point reselection criteria.

The newly deployed cell may affect the neighbor relation of the neighbor cell, and the neighbor cell may not always obtain the latest neighbor relation information from Operation and Administration (OAM) AND MAINTENANCE, where NR allows the terminal device to report the neighbor related information obtained by itself, such as the global identity (Cell Global Identity, CGI) of the cell and/or the SFN and frame timing offset (SFN AND FRAME TIMING DIFFERENCE, SFTD), under the configuration of the network device.

Fig. 3 shows a schematic flow chart of a wireless communication method 200 according to an embodiment of the application, which method 200 may be performed interactively by a terminal device and a network device. Such as terminal device 110 shown in fig. 1 and network device 120 shown in fig. 1.

As shown in fig. 3, the method 200 may include:

S210, the terminal equipment sends first characteristic information of the neighbor cells to the network equipment, wherein the first characteristic information is carried in system broadcast information of the neighbor cells or carried in neighbor cell measurement reference signals.

In other words, the terminal device reports the first characteristic information of the neighboring cell in the system broadcast information of the neighboring cell or the first characteristic information of the neighboring cell acquired through the neighboring cell measurement reference signal to the network device. Based on the first characteristic information reported by the terminal equipment, the network equipment can update the neighbor relation information of the neighbor cells. For example, the terminal device may send the first characteristic information to the network device through dedicated signaling.

In some embodiments of the application, the first characteristic information includes at least one of the following characteristic information:

public land mobile network PLMN list configuration information, independent non-public network SNPN list configuration information, access control related network identity list configuration information or temporary network identity list configuration information;

indication information of whether the terminal equipment is allowed to carry out authentication through a third party network;

Group identification information allowing the terminal device to authenticate through the third party network;

Whether the terminal equipment is allowed to initiate indication information of a network authentication request in the third party network under the condition that a SNPN identifier or a PLMN identifier used for the authentication of the third party network is not matched with any SNPN identifier or PLMN identifier broadcasted by cell system information;

Whether the terminal equipment is allowed to access in a cell of the third party network and obtain the indication information of subscription information;

Allowing terminal equipment to access and acquire group identification information of subscription information through a cell of the third party network; or (b)

Indication information whether PLMN, SNPN, access control related network identity, closed access group CAG or temporary network identity allows emergency communication.

It should be appreciated that the access control related network identification is similar to, i.e. has the same physical meaning as, the PLMN ID or SNPN ID, but the length of the access control related network identification may be different from the PLMN ID or SNPN ID. Similarly, the temporary network identity is similar to the PLMN ID or SNPN ID, i.e. the actual meaning is the same, except that it is a temporary identity of the PLMN or SNPN.

Optionally, the configuration information of the access control related network identifier list is configuration information of cell granularity, and is used for controlling the terminal device to access to a network/cell.

In other words, the first feature information includes feature information 1 to feature information 7, and the feature information 1 to feature information 7 are as follows:

Characteristic information 1: public land mobile network PLMN list configuration information, independent non-public network SNPN list configuration information, access control related network identity list configuration information or temporary network identity list configuration information;

Characteristic information 2: indication information of whether the terminal equipment is allowed to carry out authentication through a third party network;

characteristic information 3: group identification information allowing the terminal device to authenticate through the third party network;

Characteristic information 4: whether the terminal equipment is allowed to initiate indication information of a network authentication request in the third party network under the condition that a SNPN identifier or a PLMN identifier used for the authentication of the third party network is not matched with any SNPN identifier or PLMN identifier broadcasted by cell system information;

Feature information 5: whether the terminal equipment is allowed to access in a cell of the third party network and obtain the indication information of subscription information;

characteristic information 6: allowing terminal equipment to access and acquire group identification information of subscription information through a cell of the third party network; or (b)

Characteristic information 7: indication information whether PLMN, SNPN, access control related network identity, closed access group CAG or temporary network identity allows emergency communication.

Alternatively, the third party network may be a network established by a third party, and the operator authorizes to allow the third party to establish its own temporary NPN. For example, the third party network may be a temporary concert communication network or a temporary emergency communication network. The third party network may be SNPN or a CAG network, where the third party network may also be a network where the neighboring cell is located, and where the newly deployed cell is located, which is not particularly limited in the embodiment of the present application.

Or, the feature information of any one of the feature information 2 to the feature information 7 in the first feature information may be PLMN granularity, SNPN granularity, CAG granularity, access control related network identifier, cell granularity or temporary network identifier granularity.

For another example, for a terminal device capable of reading the system broadcast information of the neighboring cell and not supporting the functional characteristics corresponding to the system broadcast information of the neighboring cell, the terminal device may measure and report predefined characteristic information in the system broadcast information of the neighboring cell according to the measurement configuration information. Of course, for a terminal device that cannot read the system broadcast information of the neighboring cell, the terminal device must not report the feature information in the system broadcast information of the neighboring cell.

For another example, for a terminal device capable of reading a neighbor measurement reference signal and supporting a functional characteristic corresponding to the neighbor measurement reference signal, after the terminal device reports the capability indication information, the terminal device may measure and report predefined feature information in the neighbor measurement reference signal according to the measurement configuration information, or may decide which feature information in the neighbor measurement reference signal to measure and report according to the measurement configuration information. For another example, for a terminal device capable of reading the neighbor measurement reference signal and not supporting the functional characteristics corresponding to the neighbor measurement reference signal, the terminal device may measure and report predefined characteristic information in the neighbor measurement reference signal according to the measurement configuration information. Of course, for the terminal device that cannot read the neighbor cell measurement reference signal, the terminal device must not report the feature information in the neighbor cell measurement reference signal.
