Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12.

In order to make those skilled in the art better understand the technical solutions of the embodiments of the present invention, the following description is made.

(1) Non-public networks (NPN).

Non-public networks are distinguished from public networks, and pointers to private networks have some restrictions on users. Each non-public network has its own identification information, such as NPN-ID, or CAG-ID, etc. The non-public network may only allow authorized partial UEs to access, and other UEs cannot access the non-public network. For example, when the authorization identification information of the non-public network exists in the authorization information (description) of the UE, the UE allows access to the network. After the UE accesses the network, the network side authenticates the UE to ensure that the UE is authorized by the non-public network.

The non-public network may allow only authorized UEs access or through network mode settings while allowing access to authorized and non-authorized UEs.

(2) UE mode.

For non-public networks, the UE may hold UE mode information in addition to possibly related UE capabilities, such as: the mode of "allowing to work in a non-public network only" and the mode of "allowing to work in a public network". If the UE is in "allowed to operate only in non-public networks" mode, the UE cannot access or operate in a public network. If the UE is in "allowed to operate in public network" mode, the UE may select one of the accesses between the public network and the non-public network.

It should be noted that the UE may change between modes "allowing only to operate in a non-public network" and "allowing to operate in a public network", or may only perform one of the modes without changing.

(3) Measurement configuration and handover commands.

The network side will send the measurement configuration information in a radio resource control RRC (connection) reconfiguration message. The handover command multiplexes RRC (connection) reconfiguration message. The UE is configured with parameters such as measurement frequency points, cells and the like through a network side, the UE executes measurement in the configuration, and initiates measurement report when specific conditions are met. The network side receives the measurement report and can be used for various purposes, such as handover decision, MDT receipt collection, etc.

(4) UE capabilities.

The UE capability information holds the UE's support capabilities for various characteristics. After the UE establishes connection with the network, the core network will issue the UE capability (mainly access stratum AS capability) information to the base station network side for storage and utilization, and if the core network does not store the UE capability, the base station sends a UE capability request to the UE, the UE feeds back to the base station, after the base station network side receives the UE capability, the base station network side stores and utilizes the UE on the one hand, and sends the UE capability request to the core network on the other hand, thereby facilitating the other base stations to subsequently request the UE capability to the core network. The "whether or not the UE supports the non-public network" of the UE may be one of the UE capability information (NPN capability).

At present, a terminal measures measurement frequency points configured on a network side, and unnecessary terminal power consumption and air interface signaling overhead are increased when the terminal is in a specific working mode.

As shown in fig. 2, an embodiment of the present invention provides a transmission method, applied to a network device, including:

step 201: and receiving the indication information of the working mode of the terminal.

Here, the terminal operation mode indication information is used to indicate that the current operation mode of the terminal is a non-public network mode or a public network mode.

and when the value of the N bit is a second value, the method is used for indicating that the current working mode of the terminal is a public network mode, wherein N is an integer greater than or equal to 1.

For example, the terminal operation mode indication information is 1-bit indication information. When the value of the indication information is a first value, such as true, the value is used for indicating that the current working mode of the terminal is the non-public network mode, and when the value of the indication information is a second value, such as false, the value is used for indicating that the current working mode of the terminal is the public network mode.

Step 202: and under the condition that the terminal working mode indication information indicates that the current working mode of the terminal is a non-public network mode, acquiring target information, wherein the target information comprises at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network.

In a specific embodiment of the present invention, the network device may configure the target information itself or obtain the target information from a non-public network target base station when a current working mode of the terminal is a non-public network mode.

Step 203: and sending the target information to a terminal.

Here, when the terminal operating mode indication information indicates that the current operating mode of the terminal is the non-public network mode, the network device acquires the target information and sends the target information to the terminal, so that the terminal in the non-public network mode measures the frequency points of the cells of the non-public network or the non-public network without measuring all the measurement frequency points or the cells, thereby reducing the measurement overhead of the terminal and reducing the interface or air interface load.

The transmission method of the embodiment of the invention receives the indication information of the terminal working mode; under the condition that the terminal working mode indication information indicates that the current working mode of the terminal is a non-public network mode, target information is obtained, wherein the target information comprises at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network; and sending the target information to a terminal, so that the terminal in the non-public network mode measures the frequency points of the cells of the non-public network or the non-public network without measuring all the measurement frequency points or cells, thereby reducing the measurement overhead of the terminal and lightening the interface or air interface load.

Further, the receiving of the terminal operating mode indication information includes:

Here, it should be noted that the RRC setup complete message may be an RRC connection setup complete message in the NR system, the RRC reestablishment complete message may be an RRC connection reestablishment complete message in the NR system, the RRC recovery complete message may be an RRC connection recovery complete message in the NR system, and the RRC reconfiguration complete message may be an RRC connection reconfiguration complete message in the NR system.

Further, when the preset message is a Radio Resource Control (RRC) setup complete message, an RRC reestablishment complete message, an RRC recovery complete message or an RRC reconfiguration complete message;

the obtaining of the target information under the condition that the terminal working mode indication information indicates that the current working mode of the terminal is the non-public network mode includes:

Here, the network device may optimize the measurement configuration when the terminal operating mode indication information indicates that the current operating mode of the terminal is the non-public network mode, and directly configure the target information, that is, configure at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network, by the network device.

Further, when the preset message is a measurement report;

Here, the network device is specifically a source base station, and the terminal sends a measurement report to the network device, where the measurement report carries terminal operating mode indication information, and the terminal operating mode indication information indicates that a current operating mode of the terminal is a non-public network mode. As an alternative implementation manner, the measurement report is a measurement report sent based on the optimized measurement configuration, that is, the measurement report is a measurement report sent based on the target information, in this case, the source base station may select a non-public network target base station from non-public network base stations provided in the measurement report, and send a handover preparation message to the non-public network target base station, where the handover preparation message includes the terminal operating mode indication information; as another optional implementation manner, the measurement report is not a measurement report sent based on optimized measurement configuration, in this case, the source base station makes a handover optimization decision, excludes the public network base station, selects at least one non-public network target base station, and sends a handover preparation message to the selected non-public network target base station, where the handover preparation message includes the terminal operating mode indication information.

And then, the non-public network target base station sends a switching preparation response to the source base station according to the switching preparation message, wherein the switching preparation response comprises the target information.

Based on this, the sending the target information to the terminal includes:

Here, after receiving the handover preparation response sent by the target base station of the non-public network, the source base station sends a handover command to the terminal, and the handover command carries target information, so that the terminal in the non-public network mode measures the frequency points of the cell of the non-public network or the non-public network without measuring all the measurement frequency points or cells, thereby reducing the measurement overhead of the terminal and reducing the interface or air interface load.

And when the terminal is in the non-public network only mode, the source network side does not send the switching request to any node of the public network, but only sends the switching request to the non-public network, thereby avoiding the failure of the switching request caused by the access control of the target network side of the public network aiming at the UE in the non-public network only mode, reducing the unnecessary interface signaling overhead and shortening the switching time delay.

As shown in fig. 3, an embodiment of the present invention further provides a transmission method applied to a terminal, including:

step 301: and sending terminal working mode indication information, wherein the terminal working mode indication information is used for indicating that the current working mode of the terminal is a non-public network mode or a public network mode.

In the embodiment of the invention, the terminal can preset message sending terminal working mode indication information;

Step 302: receiving target information sent by network equipment, wherein the target information comprises at least one of a frequency point where a non-public network is located and cell identification information used by the non-public network, and the target information is sent by the network equipment according to the terminal working mode indication information.

Here, in the terminal in the non-public network mode, the network device configures at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network for the terminal, so that the terminal in the non-public network mode measures the frequency points of the cell of the non-public network or the non-public network without measuring all the measurement frequency points or cells, thereby reducing the measurement overhead of the terminal and reducing the interface or air interface load.

Further, the sending of the terminal operating mode indication information includes:

The terminal operation mode change instruction information is transmitted when the operation mode of the terminal is changed from the public network mode allowing operation to the non-public network mode only allowing operation, or is changed from the non-public network mode only allowing operation to the public network mode allowing operation. The terminal operation mode change indication information may be indication information with preset bits, for example, 1-bit indication information.

Further, the sending the terminal operating mode indication information according to the terminal operating mode change indication information includes:

The transmission method of the embodiment of the invention sends the terminal working mode indication information, wherein the terminal working mode indication information is used for indicating that the current working mode of the terminal is a non-public network mode or a public network mode; receiving target information sent by network equipment, wherein the target information comprises at least one of a frequency point where a non-public network is located and cell identification information used by the non-public network, and the target information is sent by the network equipment according to the terminal working mode indication information. The embodiment of the invention ensures that the terminal only measures the frequency points of the cells of the non-public network or the non-public network according to the target information without measuring all the measuring frequency points or the cells, thereby reducing the measuring overhead of the terminal and lightening the interface or air interface load.

The transmission method of the present invention will be described with reference to specific embodiments.

The first embodiment is as follows: and optimizing the measurement configuration.

As shown in fig. 4, the method includes:

step 401: the terminal sends RRC (connection) establishment completion information to the service base station, wherein the RRC (connection) establishment completion information carries the indication information of the working mode of the terminal.

For example, the 1-bit terminal operation mode indication information may be carried through an RRC (connection) setup complete message.

When a UE with non-public network (NPN) access capability initiates connection establishment to a network, the connection establishment completion message may carry relevant parameters of the non-public network. The UE sets a parameter indicating whether to allow the UE to operate in a Non-public network only in a Non-Access Stratum (NAC) layer, and indicates to the network side after the AS layer (Access Stratum) of the UE acquires the parameter. The indication mode is that 1bit indication is carried in RRC (connection) establishment completion message. According to the different expression modes of the indicated parameter names, the following two modes can be adopted:

TABLE 1

In the above table 1, the "True" of the first mode is the same as the "False" of the second mode (hereinafter, referred to as "non-public network only" mode), and the "False" of the first mode is the same as the "True" of the second mode (hereinafter, referred to as "public network allowed" mode). Only for NPN capable UEs. For a UE without NPN capability, there is no possibility to allow access to a non-public network, and the network side does not refer to the above indication.

Step 402: and under the condition that the terminal working mode indication information indicates that the current working mode of the terminal is a non-public network mode, configuring at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network, and sending the frequency point and the cell identification information to the terminal.

When the network side receives the indication and the UE is in the mode of 'non-public network only', the measurement configuration optimization can be carried out aiming at the UE. The configuration mode is as follows:

(1) only configuring the frequency point of the non-public network to the UE;

(2) based on the frequency point information, giving cell identification information used by a non-public network, such as PCI range information of a cell;

(3) a combination of the two.

After receiving the measurement configuration, the UE in the 'non-public network only' mode only measures on the frequency points and cells configured by the network, thereby avoiding the waste of UE power consumption and air interface overhead possibly caused by the measurement on the public network which can not be accessed.

In addition, in addition to sending the indication in the RRC (connection) setup complete message, the indication may also be carried in an RRC (connection) reestablishment complete or RRC (connection) recovery complete or RRC (connection) reconfiguration complete message. The method can be used for informing the network side of the change of the UE mode or indicating the current mode of the UE to the network when the UE enters a non-public network from a public network.

Example two: and (6) switching judgment optimization.

As shown in fig. 5, the method includes:

step 501: and the terminal sends a measurement report to the source base station, wherein the measurement report carries the indication information of the working mode of the terminal.

Step 502: and the source base station performs switching judgment optimization processing according to the measurement report, excludes the public network base station, and sends a switching preparation message to the non-public network target base station.

Step 503: and the non-public network target base station sends a switching preparation response to the source base station through access control, wherein the switching preparation response comprises at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network.

Step 504: and the source base station sends a switching command to the terminal, wherein the switching command carries at least one of a frequency point where the non-public network is located and cell identification information used by the non-public network.

In this embodiment, when the terminal is in the non-public network only mode, the source network side does not send the handover request to any node of the public network, but only sends the handover request to the non-public network, thereby avoiding the handover request failure caused by the access control of the target network side of the public network for the UE in the non-public network only mode, reducing unnecessary interface signaling overhead, and shortening the handover delay.

And in the switching process, the target network side organizes the content of the switching command based on the information carried in the switching preparation message given by the source network side. In order for the target network side to send the optimized measurement configuration directly to the UE in the handover command, the information of whether the UE is "allowed to operate only in the non-public network" mode needs to be transferred between nodes. The non-public network target base station configures measurement in the handover command for the UE according to the indication, and the specific configuration mode refers to the first embodiment.

Example three: mode change of the UE.

The UE's "non-public network" mode is typically maintained above the AS layer (typically the NAS layer). After the UE mode is changed, the NAS layer of the UE may notify the AS layer of the UE and report to the network side:

1) if the idle state or inactive state UE has mode change of "allowing only operation in the non-public network", the UE mode change may be indicated to the network side when subsequently establishing/restoring connection.

2) If the connected UE has mode change of 'allowing only to work in a non-public network', the change indication can be immediately sent to the network side, and the change indication can be transmitted in the UE uplink auxiliary information.

The change indication is an indication of the mode in which the UE is currently actually located, and may be 1-bit indication information.

According to the transmission method provided by the embodiment of the invention, the terminal in the non-public network mode only measures the frequency points of the cells of the non-public network or the non-public network, and does not need to measure all the measurement frequency points or cells, so that the measurement overhead of the terminal can be reduced, and the interface or air interface load can be reduced.

As shown in fig. 6, an embodiment of the present invention further provides a network device, which may be specifically a base station, and includes a memory 620, a processor 600, a transceiver 610, a bus interface, and a program stored in the memory 620 and executable on the processor 600, where the processor 600 is configured to read the program in the memory 620 and execute the following processes:
