Detailed ways

In order to understand the features and technical contents of the embodiments of the present application in more detail, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Before describing the embodiments of the present application, relevant contents are briefly described.

At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP international standards organization has begun to develop 5G. The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

Among them, since eMBB still aims at users to obtain multimedia content, services and data, the demand for eMBB is growing very rapidly. Since eMBB can be deployed in different scenarios, such as indoors, urban areas, and rural areas, its capabilities and requirements are also quite different. Therefore, the application of eMBB needs to be combined with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), and traffic safety assurance. The typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules.

The NR system can also be deployed independently. In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, a new Radio Resource Control (RRC) state is defined, namely the RRC-Inactive state. Among them, in the idle (RRC-Idle) state, the mobility is cell reselection based on terminal equipment, the paging process is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no terminal device context and no RRC connection on the network device side. In the RRC-Inactive state, mobility is cell reselection based on the terminal equipment, there is a connection between CN-NR, the terminal equipment context exists on a certain network equipment, the paging process is triggered by the RAN, and the paging area based on the RAN Managed by the RAN, the network equipment can know the location of the terminal equipment based on the paging area level of the RAN.

The access control mechanism of the access network includes two types, namely, the access control mechanism at the cell level and the access control mechanism at the service type level. The main purpose of the access control mechanism at the cell level is to indicate whether the terminal equipment can camp on the cell; for example, the network equipment indicates whether the terminal equipment can camp on the prohibition indication bit in the Main Information Block (MIB). When camping on the cell, if the camping prohibition indication bit in the MIB indicates a prohibited state, any terminal equipment cannot camp on the cell. The main purpose of the access control mechanism at the service type level is to control different services to access the current serving cell with different success probabilities, thereby reducing the possibility of system resource congestion; the terminal equipment that performs service type level access control must not be Camping is prohibited by cell-level access control mechanisms.

NPN network can be flexibly deployed as SNPN network and CAG network. ID and CAG ID are identified together.

A PLMN network can support any combination mode of common public network, SNPN network and CAG network at the same time. For example, a PLMN can support common public network or SNPN network or CAG network alone, and can also support common public network and SNPN network sharing. A PLMN network, even common public network, SNPN network and CAG network sharing a PLMN network at the same time are allowed. The logical deployment relationship among the common public network, SNPN network and CAG network is shown in Table 1 below:

Table 1. Network Identity Configurations Supported by Cells

As can be seen from Table 1, from the perspective of network device configuration, a cell can be configured with public network PLMN ID list information and NPN network identification list information at the same time; wherein, the NPN network identification list information is an optional parameter introduced by NR R16. NPN, allows a PLMN ID to be associated with a CAG ID list; for SNPN type NPN networks, allows a PLMN ID to be associated with a NID list. The parameters N, M and W in Table 1 are all positive integers greater than or equal to 1.

In addition to flexibly deploying NPN networks as SNPN networks and CAG networks, third parties can also deploy their own NPN networks under the authorization of operators. The NPN network deployed by a third party has brand-new network features, and the network equipment section informs the terminal device of these new network feature information through system information. However, not all terminal devices support the NPN network deployed by the third party. At the same time, not all NPN networks support the function of third-party deployment of NPN networks. Therefore, how to control different types of terminal devices to access the NPN network deployed by the third party is an urgent problem to be solved, and the prior art does not disclose a solution for performing access control for the NPN network deployed by the third party.

The network access method provided by the embodiment of the present application enables the terminal device to determine whether to access the NPN network according to the access control configuration information of the NPN network, the feature configuration information of the NPN network, and the configuration information of the terminal device itself, so that the terminal device can quickly and easily access the NPN network. Accurate access to the NPN network.

The following describes the information included in the access control configuration information of the NPN network, respectively.

For the first indication information, it can indicate whether the cell is reserved for the NPN function; if the first indication information indicates that the cell is reserved for the NPN function, the terminal device can determine that the cell only supports the NPN function after obtaining the first indication information; The terminal device can filter out some cells that are not suitable for access according to its own service capability and the first indication information. For example, if the first indication information indicates that the cell is reserved exclusively for the NPN function, that is, the cell only supports the NPN function, the non-NPN terminal equipment cannot select the cell to initiate normal services.

For the first indication information, it can also indicate whether the cell supports the NPN function, and whether the cell supports the public network service function cannot be determined according to the first indication information. The terminal can filter out some cells that are not suitable for access according to its own service capability and the first indication information.

The description and application of the second indication information, the third indication information, and the fourth indication information are similar to the description and application of the first indication information, and will not be repeated here.

In this embodiment of the present application, the fifth indication information or the sixth indication information is further used to indicate whether the cell is reserved for use in a subsequent protocol version. For example, it indicates whether the cell is reserved for the protocol version after R16. In this scenario, the fifth indication information may only be used to indicate whether the cell is reserved for use by other functions, and the sixth indication information may be used to indicate whether the cell is reserved for future function use in addition to indicating whether the cell is reserved for use by future functions. Reserved for subsequent protocol versions. In this scenario, the fifth indication information can also be used to indicate whether the cell is reserved for use in subsequent protocol versions in addition to indicating whether the cell is reserved for use by other functions; the sixth indication information is only used to indicate the cell Whether to reserve for future feature use.

Alternatively, the access control configuration information of the NPN network further includes seventh indication information indicating whether the cell is reserved for use in subsequent protocol versions; in this scenario, the fifth indication information is only used to indicate whether the cell is reserved for other functions Used, the sixth indication information is only used to indicate whether the cell is reserved for future functional use.

In this embodiment of the present application, the terminal device can obtain the first to seventh indication information only if the protocol version supported by the terminal device is higher than or equal to the protocol version that defines the first to seventh indication information; When the protocol version supported by the device is lower than the protocol version defining the first indication information to the seventh indication information, the terminal device cannot obtain the first indication information to the seventh indication information.

In some embodiments, if the access control configuration information of the NPN network includes the first indication information to the sixth indication information, but does not include the seventh indication information, the first indication information and the second indication information , each of the third indication information, the fourth indication information, the fifth indication information and the sixth indication information corresponds to a first information field. It can be understood that the number of first information fields is in one-to-one correspondence with the number of indication information. If there is the first indication information, the second indication information, the third indication information, the fourth indication information, The fifth indication information and the sixth indication information, the number of the first information fields is six, the first indication information, the second indication information, the third indication information, the fourth indication The information, the fifth indication information and the sixth indication information respectively correspond to one of the six first information fields. The bit value of each first information field is used to represent the corresponding indication information.

Similarly, if the access control configuration information of the NPN network includes the first indication information to the seventh indication information, the first indication information, the second indication information, the third indication information, the Each of the four indication information, the fifth indication information, the sixth indication information and the seventh indication information corresponds to a third information field.

Taking the existence of seven indication information from the first indication information to the seventh indication information as an example, the corresponding relationship between the indication information and the third information field can be shown in Table 3 below:

Table 3. Correspondence between indication information and third information field

As shown in Table 3, if the bit value of the third information field 1 is 1, that is, the value corresponding to the third information field 1 is true, it indicates that the first indication information indicates whether the cell supports the NPN network or not; if the third information The bit value of field 2 is 0, that is, the value corresponding to the third information field 2 is not true, indicating that the second indication information indicates that the cell does not support the function of allowing the terminal device to access the network through the cell to perform third-party authentication or registration. It is limited, that is, any terminal device can access the network through the cell to perform third-party authentication or registration functions; if the bit value of the third information field 3 is 1, that is, the value corresponding to the third information field 3 is true, then The third indication information indicates whether the cell supports the function of allowing the terminal device to obtain new subscription information or update the existing subscription information through the cell access network; if the bit value of the third information field 4 is 0, that is, the first The value corresponding to the third information field 4 is not true, which means that the fourth indication information indicates that it does not limit whether the cell supports the third-party authentication or registration function that allows the terminal device to access the network through the cell, and does not support the function of allowing the terminal device to access the network.

The value of the second information field combination is 2-7, which correspond to the third indication information to the eighth indication information respectively. When the value of the first information field combination can be predefined as 2-7, the corresponding indication information is " true" or "not true"; for example, if the value of the second information field combination is defined as 2, and the value of the corresponding indication information is "true", then the value of the second information field combination is 2 corresponding to the third indication The information indication defines whether the cell supports the function of allowing the terminal device to obtain new subscription information or update existing subscription information through the cell's access to the network.
