Description

SNPN cell access method, device and storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an access method, device, and storage medium for an SNPN cell.

Background

A new type of network, non-public network (NPN), was introduced in the 5g r16 version. The NPN can be deployed in various ways, and can be deployed independently from the existing 5G Public Network (SNPN), or can be deployed on the existing 5G Public Network (PNI-NPN) in a sharing way.

User Equipment (UE) needs to access an SNPN network, and needs to store SNPN User subscription data at a UE side, where the SNPN User subscription data may be stored in a Universal Subscriber Identity Module (USIM) in advance, and the UE may access the corresponding SNPN network using a specific USIM card. For some application scenarios of the SNPN network, such as factory equipment, there is an optimizable space for configuring a special USIM card for each newly added equipment, both from the viewpoint of flexibility and cost.

And 5G R17 puts forward a new demand for SNPN, that is, UE may not use a USIM card pre-configured with SNPN user subscription data, and use a novel SNPN user subscription data loading network (hereinafter referred to as onkeying SNPN) for remote loading of user subscription data, and UE without SNPN user subscription data may reside in the onkeying SNPN, and remotely obtain SNPN user subscription data through the onkeying SNPN, and then use the obtained SNPN user subscription data to register in a target SNPN network, and use the service provided by the SNPN network.

Therefore, how the UE can identify whether the SNPN cell supports user subscription data loading (associating) to complete the SNPN user subscription data loading becomes an urgent problem in the industry.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and actions, those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order.

In the specification of the SNPN at 5G R17, the UE may complete the remote loading of the SNPN user subscription data through the onkeying SNPN cell without using a USIM card configured with the SNPN user subscription data in advance, that is, the UE without the SNPN user subscription data may reside in the onkeying SNPN, and remotely obtain the SNPN user subscription data through the onkeying SNPN, and then register to the target SNPN network using the obtained SNPN user subscription data, using the service provided by the SNPN network.

Fig. 1 is a schematic diagram of a process of remotely loading SNPN subscriber subscription data according to an embodiment of the present invention, and as shown in fig. 1, the process may specifically include:

1. the UE resides in an Onboarding SNPN and accesses a subscription data granting Server (Provisioning Server) through the Onboarding SNPN;

2. the Provisioning Server acquires SNPN user subscription data of the UE from a target SNPN;

3. the Provisioning Server sends SNPN user subscription data to the UE through a data transmission channel provided by the Onboarding SNPN;

4. the UE registers to the target SNPN network using the loaded SNPN user subscription data.

Therefore, in order to enable the UE to successfully access the subscription data granting server through the onbroadcasting SNPN cell after residing in the onbroadcasting SNPN cell, and complete loading of the SNPN user subscription data, the UE needs to be able to identify whether the SNPN cell supports the UE to perform user subscription data loading, so as to further complete the SNPN user subscription data loading.

The core idea of each embodiment of the invention is as follows: the NG-RAN indicates whether the current SNPN cell of the terminal supports SNPN association or not so as to ensure that the terminal selects the SNPN cell supporting SNPN association when the cell is selected.

The present invention is described in detail below with reference to various embodiments.

Fig. 2 is a schematic flow chart of an access method of an SNPN cell according to an embodiment of the present invention; as shown in fig. 2, the method comprises the steps of:

step 200, receiving first indication information sent by a network side, wherein the first indication information is used for indicating whether a current SNPN cell supports SNPN user subscription data loading;

specifically, if the terminal needs to complete the remote loading of the SNPN user subscription data through the onbroadcasting SNPN cell, that is, when the terminal has a requirement for loading the SNPN user subscription data, the terminal receives first indication information sent by the network side in order to determine whether the current SNPN cell supports the SNPN user subscription data loading (SNPN onbroadcasting). It can be understood that the terminal adds a function capable of receiving a first indication message of an SNPN cell when an SNPN subscriber subscription data loading (SNPN associating) is required.

In this embodiment, the network side sends a first indication message to the terminal to indicate whether the current SNPN cell of the terminal supports SNPN user subscription data loading (SNPN associating), and after receiving the first indication message, the terminal may determine whether the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to the first indication message.

In this embodiment, before receiving first indication information sent by a network side, a terminal first triggers a process of selecting an onboarding SNPN cell supporting SNPN user subscription data loading (SNPN associating), performs cell search, implements downlink synchronization with a current SNPN cell, and finally reads a first indication message, and determines whether the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to the first indication message;

it can be understood that, in this embodiment, an SNPN cell supporting SNPN user subscription data loading (SNPN associating) may be referred to as an associating SNPN cell.

Step 201, if it is determined that the current SNPN cell supports loading of SNPN user subscription data according to the first indication information, accessing the current SNPN cell to complete loading of SNPN user subscription data.

Specifically, after the terminal receives the first indication information, if the terminal determines that the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to the first indication information, the terminal may access the current SNPN cell, and then remotely obtain the SNPN user subscription data through the current SNPN cell.

For example, when a terminal determines whether an SNPN supports SNPN user subscription data loading (SNPN associating) by reading a first indication message and then selects an associating SNPN cell, first, the UE triggers a process of selecting the associating SNPN cell, then, after the UE synchronizes to a current SNPN cell, obtains the first indication message, determines that the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to an "associating Indicator" in the first indication message, and then, may access the current SNPN cell, and further, remotely obtains the SNPN user subscription data through the current SNPN cell.

According to the SNPN cell access method provided by the embodiment of the invention, whether the current SNPN cell supports SNPN user subscription data loading or not is determined according to the first indication information by receiving the first indication information sent by the network side, and after the current SNPN cell supports SNPN user subscription data loading is determined, the current SNPN cell is accessed to complete SNPN user subscription data loading, so that the problems that whether the SNPN cell supports or not cannot be identified by a terminal in the prior art and the SNPN user subscription data loading of the terminal on the cell is allowed are solved, and the access flexibility and efficiency of the SNPN cell are improved.

Optionally, on the basis of the foregoing embodiments, the first indication information is used to indicate whether the current SNPN cell supports loading of subscription data of an SNPN user, and specifically includes: the SNPN cell is used for indicating that the current SNPN cell only supports SNPN user subscription data loading;

specifically, when the network side indicates whether or not to support SNPN subscription data loading (SNPN associating) by sending the first indication message, the indication manner that may be adopted is:

mode 1: indicating that the current SNPN cell supports only SNPN user subscription data loading (SNPN associating).

In this embodiment, when the network side indicates to the terminal whether the current SNPN cell supports SNPN user subscription data loading (SNPN associating), the network side may indicate, in a manner 1, that the current SNPN cell only supports SNPN user subscription data loading (SNPN associating), that is, the current SNPN cell does not support terminal access that does not require SNPN user subscription data loading (SNPN associating).

Specifically, after the terminal receives a network side indicating that the current SNPN cell only supports SNPN user subscription data loading (SNPN associating), if the terminal also needs to perform the SNPN user subscription data loading (SNPN associating), the terminal may access the current SNPN cell, and then remotely obtain the SNPN user subscription data through the current SNPN cell.

Optionally, on the basis of the foregoing embodiments, the method further includes:

Specifically, after the terminal receives a network side indicating that the current SNPN cell only supports loading of SNPN user subscription data (SNPN associating), if the terminal does not need to perform the loading of the SNPN user subscription data (SNPN associating), for example, when the terminal already stores the user subscription data or the terminal does not need to acquire the user subscription data through the associating SNPN cell, the terminal does not access the current SNPN cell.

In this embodiment, a terminal that does not need to perform SNPN subscriber subscription data loading (SNPN associating) may be referred to as a normal SNPN UE. That is, the ordinary SNPN UE may add a function capable of receiving first indication information, which is sent by the network side and used to indicate that the current SNPN cell only supports loading of SNPN subscription data, so as to avoid camping on the SNPN cell that only supports loading of SNPN subscription data.

For example, a terminal in an SNPN mode, which is a normal SNPN UE and does not need to load SNPN user subscription data, determines whether to camp in an SNPN cell according to first indication information indicating that only SNPN user subscription data loading (SNPN associating) is supported by a network.

Specifically, in cell selection, an SNPN cell supporting loading of SNPN user subscription data is first used as a candidate cell by a common SNPN UE, and then first indication information sent by the candidate SNPN cell and used for indicating UE access only supporting loading of the SNPN user subscription data is received, and if the first indication information received by the common SNPN UE obtains that the current SNPN cell only supports loading of the SNPN user subscription data (SNPN barring), the common SNPN UE does not select the SNPN cell for access.

Optionally, on the basis of the foregoing embodiments, the first indication information is used to indicate whether the current SNPN cell supports SNPN user subscription data loading, and specifically includes: the SNPN terminal equipment is used for indicating the current SNPN cell to simultaneously support SNPN user subscription data loading and not needing to carry out SNPN user subscription data loading;

specifically, when the network side indicates whether or not the SNPN subscription data loading (SNPN associating) is supported by sending the first indication message, the method that may be further adopted is:

mode 2: and indicating the current SNPN cell to simultaneously support SNPN user subscription data loading (SNPN associating) and terminal access without SNPN user subscription data loading (SNPN associating).

Specifically, when the network side indicates the terminal whether the current SNPN cell supports SNPN subscriber subscription data loading (SNPN associating), the network side may indicate, in a manner 2, that the current SNPN cell simultaneously supports SNPN subscriber subscription data loading (SNPN associating) and terminal access that does not require the SNPN subscriber subscription data loading (SNPN associating).

Correspondingly, if it is determined that the current SNPN cell supports SNPN user subscription data loading according to the first indication information, accessing the current SNPN cell to complete SNPN user subscription data loading, including:

and if the current SNPN cell supports SNPN user subscription data loading and the SNPN user subscription data loading is determined to be required according to the first indication information, accessing the current SNPN cell to finish the SNPN user subscription data loading.

Specifically, after a terminal receives a network side indication that a current SNPN cell simultaneously supports SNPN user subscription data loading (SNPN associating) and terminal access which does not need to carry out SNPN user subscription data loading (SNPN associating), the terminal can consider that the current SNPN cell not only supports SNPN user subscription data loading, but also supports common SNPN UE (service provider node) that does not need to carry out SNPN user subscription data loading;

if the terminal also needs to perform SNPN user subscription data loading (SNPN associating), the terminal may access the current SNPN cell, and further remotely obtain the SNPN user subscription data through the current SNPN cell.

Specifically, after the terminal receives an indication from the network side that the current SNPN cell supports SNPN user subscription data loading (SNPN associating), if the terminal does not need to perform SNPN user subscription data loading (SNPN associating), for example, when the terminal already stores user subscription data or the terminal does not need to obtain user subscription data through the onassociating SNPN cell, the terminal may select to access the current SNPN cell or not access the current SNPN cell.

For example, a common SNPN UE, that is, a terminal in an SNPN mode that does not need to perform loading of SNPN user subscription data, determines whether to camp in an SNPN cell according to first indication information that a network indicates that the terminal supports both loading of SNPN user subscription data (SNPN associating) and loading of SNPN user subscription data (SNPN associating) is accessed.

Specifically, in cell selection, a common SNPN UE firstly uses an SNPN cell supporting SNPN user subscription data loading as a candidate cell, and then receives first indication information sent by the candidate SNPN cell, and if the first indication information received by the common SNPN UE obtains a current SNPN cell and simultaneously supports SNPN user subscription data loading (SNPN associating) and a terminal access which does not need to perform the SNPN user subscription data loading (SNPN associating), the terminal can automatically select to access the current SNPN cell or not access the current SNPN cell.

Optionally, on the basis of the foregoing embodiments, the first indication information is carried in one of the following manners:

Specifically, when the network side sends the first indication message, the first indication message may be carried by downlink control information on a system message, a master information block, or a physical downlink control channel.

For example, if the first indication message is carried by a System message, the terminal reads System Information, such as SIB1 (System Information Block 1) on the network side, to indicate whether the SNPN supports SNPN subscriber data loading (SNPN associating) or not, so as to select an associating SNPN cell.

Specifically, firstly, the UE triggers a process of selecting an associating SNPN cell, then after the UE synchronizes to the current SNPN cell, reads system information SIB1 of the current SNPN cell, obtains SNPN associating data load (SNPN associating) supported by the current SNPN cell according to an "associating Indicator" in the SIB1, can access the current SNPN cell, and further remotely obtains the SNPN user associating data through the current SNPN cell.

For example, if the first indication message is carried by a Master Information Block MIB (Master Information Block), the terminal reads the Master Information Block MIB sent by the network side to indicate whether SNPN supports SNPN user subscription data loading (SNPN associating) or not, so as to select an associating SNPN cell.

Specifically, firstly, the UE triggers a process of selecting an associating SNPN cell, then after the UE synchronizes to the current SNPN cell, reads a master information block MIB of the current SNPN cell, obtains an associating Indicator in the master information block MIB that supports SNPN user subscription data loading (SNPN associating) of the current SNPN cell, and then can access the current SNPN cell, thereby remotely obtaining the SNPN user subscription data through the current SNPN cell.

For example, if the first indication message is carried by downlink control information on a physical downlink control channel, the terminal indicates whether the SNPN supports SNPN user subscription data loading (SNPN associating) by reading the downlink control information on the physical downlink control channel sent by the network side, so as to select an associating SNPN cell.

Specifically, first, the UE triggers a process of selecting an uplink SNPN cell, then after the UE synchronizes to the current SNPN cell, the UE starts monitoring a PDCCH (Physical Downlink Control Channel) and analyzes Downlink Control Information DCI (Downlink Control Information), obtains SNPN subscription data loading (SNPN subscription) supported by the current SNPN cell according to the Downlink Control Information DCI, and then can access the current SNPN cell, thereby remotely obtaining the SNPN subscription data through the current SNPN cell.

specifically, after the terminal resides in an on-paging SNPN cell, the terminal triggers measurement on an adjacent cell along with the change of the signal quality of the serving cell, so the terminal may also receive second indication information sent by the network side, and obtain whether the SNPN adjacent cell of the current SNPN cell supports SNPN user subscription data loading (SNPN on-paging) according to the second indication information.

Accordingly, the method further comprises:

Specifically, a terminal that needs to perform SNPN user subscription data loading (SNPN associating) may receive and store second indication information that is sent by a network side and used to indicate whether an SNPN neighboring cell of the current SNPN cell supports SNPN user subscription data loading, and after determining that the SNPN neighboring cell of the current SNPN cell supports SNPN user subscription data loading according to the second indication information, measure the neighboring cell and evaluate whether to reselect the neighboring cell, so as to implement reselecting another SNPN cell that supports SNPN user subscription data loading (SNPN associating) when reselecting the cell.

Optionally, on the basis of the foregoing embodiments, the second indication information is carried by downlink control information on a system message, a master information block, or a physical downlink control channel.

Specifically, when the network side sends the second indication message, the second indication message may be carried by downlink control information on a system message, a master information block, or a physical downlink control channel.

For example, the terminal reselects to another one of the enhancing SNPN cells according to the system information, for example, the second indication information indicating whether the SNPN neighbor cell of the current SNPN cell in SIB3 or SIB4 supports the loading of the SNPN user subscription data.

Specifically, after the terminal resides in an associating SNPN cell, the terminal triggers measurement of an adjacent cell along with the change of the signal quality of the serving cell, and then the terminal obtains, according to an "associating Indicator" in system information SIB3, that the SNPN adjacent cell of the current SNPN cell supports SNPN user subscription data loading (SNPN associating), and may use the SNPN adjacent cell as a candidate cell for cell reselection, measure the adjacent cell, and evaluate whether to reselect the adjacent cell.

Specifically, after receiving the first indication information and determining that the current SNPN cell supports loading of SNPN user subscription data (SNPN associating) according to the first indication message, or after receiving the second indication information sent by the network side and determining that the SNPN neighbor cell of the current SNPN cell supports loading of SNPN user subscription data, the terminal may further receive third indication information sent by the network side and determine a list of terminal devices for loading the SNPN user subscription data, to which the current SNPN cell allows to access, according to the third indication information.

It can be understood that, when the SPNP subscriber subscription data loading is required, the terminal adds a function capable of receiving the third indication information sent by the network side and determining, according to the third indication information, a list of terminal devices that are allowed to access and perform SNPN subscriber subscription data loading.

For example, after the terminal triggers a process of selecting an enhancing SNPN cell and synchronizes to a target cell, the terminal receives first indication information sent by a network side; determining that the current SNPN cell supports SNPN user subscription data loading by using an 'associating _ Indicator' in the first indication message according to the first indication message; and further checking third indication information sent by the network side, determining whether the terminal is matched with the equipment list in the third indication information according to the equipment list supported by the current SNPN cell indicated by the third indication information by using supported _ DeviceList, if the terminal is determined to be in the equipment list supported by the current SNPN cell indicated by the third indication information, accessing the terminal to the current SNPN cell, and remotely acquiring the SNPN user subscription data through the current SNPN cell.

For example, after a terminal camps on an uplink SNPN cell, the terminal triggers measurement of neighboring cells along with the change of signal quality of a serving cell; the terminal receives a second indication message sent by the network side, and then the terminal determines that the SNPN neighbor cell of the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to an 'associating Indicator' in the second indication message; if the SNPN adjacent cell does not support SNPN user subscription data loading, the SNPN adjacent cell is not used as a candidate cell for cell reselection; if the second indication information indicates that the SNPN adjacent cell supports the SNPN user subscription data loading by using an 'onboardingindicator', further checking third indication information sent by a network side, and determining whether the terminal is matched with a device list supported by the SNPN adjacent cell according to the device list supported by the adjacent cell indicated by the third indication information by using a 'supported _ DeviceList'; and if the terminal is determined to be in the device list supported by the adjacent cell indicated by the third indication information, taking the SNPN adjacent cell as a candidate cell for cell reselection, measuring the adjacent cell, and evaluating whether the adjacent cell is reselected.

Optionally, on the basis of the foregoing embodiments, the terminal device list includes: a list of device types and/or a list of supported device vendors.

Specifically, when the network side indicates to the terminal which devices are allowed to access the network for SNPN subscription data loading (SNPN associating), any one of the following lists may be configured in a supported device list ("supported device list"):

list 1. List of supported device types;

list 2. List of supported device manufacturers;

list 3. List of supported device types and list of supported device vendors.

For example, the terminal triggers a process of selecting an enhancing SNPN cell, then the terminal acquires first indication information after synchronizing to a target cell, if the first indication information indicates that the current SNPN cell supports SNPN user subscription data loading, the terminal further checks third indication information sent by a network side, and determines a list 1 device type list supported by the current SNPN cell according to the third indication information; and if the type of the terminal is one type in the list 1 device type list supported by the current SNPN cell indicated by the third indication information, the terminal resides in the current SNPN cell and remotely acquires the SNPN user subscription data through the current SNPN cell.

Optionally, on the basis of the foregoing embodiments, the third indication information is carried by a system message and/or a master information block.

Specifically, when the network side sends the third indication message, the third indication message may be carried by a system message and/or a master information block.

For example, the terminal triggers a process of selecting an on-coding SNPN cell, then after the UE synchronizes to the current SNPN cell, the UE starts to monitor a PDCCH (Physical Downlink Control Channel) and analyze Downlink Control Information DCI (Downlink Control Information), obtains subscription data loading of an SNPN user supported by the current SNPN cell according to the Downlink Control Information DCI, and then may further obtain first indication Information carried by a Master Information Block (MIB) sent by the network side, and determines a device type list supported by the current SNPN cell according to the MIB; and if the type of the terminal is one of the device type lists supported by the current SNPN cell indicated by the MIB, the terminal resides in the current SNPN cell and remotely acquires the SNPN user subscription data through the current SNPN cell.

According to the SNPN cell access method provided by the embodiment of the invention, whether the current SNPN cell supports SNPN user subscription data loading or not is determined according to the first indication information by receiving the first indication information sent by the network side, and after the current SNPN cell supports SNPN user subscription data loading is determined, the current SNPN cell is accessed to complete SNPN user subscription data loading, so that the problems that whether the SNPN cell supports SNPN and the terminal is allowed to carry out SNPN user subscription data loading on the cell cannot be identified by the terminal in the prior art are solved, and the access flexibility and efficiency of the SNPN cell are improved.

Fig. 3 is a schematic flow chart of an access method of an SNPN cell according to another embodiment of the present invention; as shown in fig. 3, the method comprises the steps of:

step 300, sending first indication information to a terminal device, where the first indication information is used to indicate whether a current SNPN cell supports SNPN user subscription data loading, so that if the terminal device determines that the current SNPN cell supports SNPN user subscription data loading according to the first indication information, the terminal device accesses the current SNPN cell to complete SNPN user subscription data loading.

Specifically, if the terminal needs to complete the remote loading of the SNPN user subscription data through the onkeying SNPN cell, that is, when the terminal has a requirement for loading the SNPN user subscription data, the network side may send the first indication information to the terminal in order to enable the terminal to determine whether the current SNPN cell supports the loading of the SNPN user subscription data. It can be understood that, the network side adds a function of sending an indication message to the terminal to indicate whether the current SNPN cell of the terminal supports SNPN subscription data loading (SNPN associating).

In this embodiment, before the network side sends the first indication information to the terminal, the terminal first triggers a process of selecting an onbroadcasting SNPN cell that supports SNPN user subscription data loading (SNPN onbroadcasting), performs cell search, implements downlink synchronization with the current SNPN cell, finally reads the first indication information sent by the network side, and determines whether the current SNPN cell supports SNPN user subscription data loading (SNPN onbroadcasting) according to the first indication information.

Specifically, after the network side sends the first indication message to the terminal, if the terminal determines that the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to the first indication message, the terminal may access the current SNPN cell, and further remotely obtain the SNPN user subscription data through the current SNPN cell.

For example, a network side sends a first indication message to a terminal, the terminal determines whether an SNPN supports loading of SNPN user subscription data (SNPN associating) by reading the first indication message, and then when an associating SNPN cell is selected, first, the UE triggers a process of selecting the associating SNPN cell, then after the UE synchronizes to the current SNPN cell, the network side sends the first indication message to the terminal, the terminal determines that the current SNPN cell supports loading of the SNPN user subscription data (SNPN) according to an "associating Indicator" in the first indication message, and then the terminal can access the current SNPN cell, and further remotely obtains the SNPN user subscription data through the current SNPN cell.

According to the SNPN cell access method provided by the embodiment of the invention, the terminal determines whether the current SNPN cell supports SNPN user subscription data loading or not according to the first indication information by sending the first indication information to the terminal, and after the current SNPN cell supports SNPN user subscription data loading is determined, the current SNPN cell is accessed to complete SNPN user subscription data loading, so that the problems that whether the SNPN cell supports SNPN user subscription data loading or not cannot be identified by the terminal in the prior art and the terminal is allowed to carry out SNPN user subscription data loading on the cell are solved, and the access flexibility and efficiency of the SNPN cell are improved.

Optionally, on the basis of the foregoing embodiments, the first indication information is used to indicate whether the current SNPN cell supports SNPN user subscription data loading, and specifically includes:

And the SNPN terminal equipment is used for indicating the current SNPN cell to simultaneously support the SNPN user subscription data loading and the access of the SNPN terminal equipment which does not need to carry out the SNPN user subscription data loading.

Specifically, when the network side indicates to the terminal whether the current SNPN cell supports SNPN user subscription data loading (SNPN associating), the mode 1 may be adopted to indicate that the current SNPN cell only supports SNPN user subscription data loading (SNPN associating), that is, the current SNPN cell does not support terminal access that does not require SNPN user subscription data loading (SNPN associating).

Correspondingly, after the terminal receives the indication that the current SNPN cell only supports SNPN user subscription data loading (SNPN associating) from the network side, if the terminal also needs to carry out SNPN user subscription data loading (SNPN associating), the terminal accesses the current SNPN cell and then remotely obtains the SNPN user subscription data through the current SNPN cell.

If the terminal receives the indication that the current SNPN cell only supports SNPN user subscription data loading (SNPN associating) from the network side, and the terminal does not need to perform the SNPN user subscription data loading (SNPN associating), for example, the terminal already stores the user subscription data or the terminal does not need to acquire the user subscription data through the Onboarding SNPN cell, the terminal does not access the current SNPN cell.

For example, a terminal in an SNPN mode, which is not required to load SNPN user subscription data, of a general SNPN UE determines whether to camp on an SNPN cell according to first indication information indicating that only SNPN user subscription data loading (SNPN associating) is supported by a network.

Specifically, when the network side indicates to the terminal whether the current SNPN cell supports SNPN subscriber data loading (SNPN associating), the network side may also indicate, in a manner 2, that the current SNPN cell simultaneously supports SNPN subscriber data loading (SNPN associating) and terminal access that does not require SNPN subscriber data loading (SNPN associating).

After a network side indicates a current SNPN cell to a terminal and simultaneously supports SNPN user subscription data loading (SNPN associating) and the terminal access without the SNPN user subscription data loading (SNPN associating), if the terminal also needs to carry out the SNPN user subscription data loading (SNPN associating), the terminal accesses the current SNPN cell, and then remotely obtains the SNPN user subscription data through the current SNPN cell.

After a network side indicates a current SNPN cell to a terminal and simultaneously supports SNPN user subscription data loading (SNPN associating) and the terminal which does not need to carry out the SNPN user subscription data loading (SNPN associating) to access, if the terminal does not need to carry out the SNPN user subscription data loading (SNPN associating), for example, the terminal stores user subscription data or the terminal does not need to obtain the user subscription data through the Onboarding SNPN cell, the terminal can automatically select to access the current SNPN cell or not access the current SNPN cell.

For example, a general SNPN UE, that is, a terminal in an SNPN mode that does not need to perform loading of SNPN user subscription data, determines whether to camp in an SNPN cell according to first indication information that indicates that the terminal supports both loading of SNPN user subscription data (SNPN associating) and loading of SNPN user subscription data (SNPN associating) to access the terminal.

system messages, master information blocks and downlink control information on a physical downlink control channel.

For example, if the network side carries the first indication message through the System message when sending the first indication message, the terminal indicates whether the SNPN supports SNPN subscriber data loading (SNPN associating) by reading System Information such as SIB1 (System Information Block 1 ), so as to select an associating SNPN cell.

Specifically, firstly, the UE triggers a process of selecting an associating SNPN cell, then after the UE synchronizes to the current SNPN cell, reads system information SIB1 of the current SNPN cell, obtains SNPN user subscription data loading (SNPN associating) supported by the current SNPN cell according to an "associating Indicator" in the SIB1, and then can access the current SNPN cell, thereby remotely obtaining the SNPN user subscription data through the current SNPN cell.

For example, if the network side carries the first indication message through a Master Information Block MIB (Master Information Block), the terminal reads the Master Information Block MIB to indicate whether SNPN supports SNPN user subscription data loading (SNPN associating) to select an associating SNPN cell.

Specifically, firstly, the UE triggers a process of selecting an on-broadcasting SNPN cell, then, after the UE synchronizes to the current SNPN cell, reads a master information block MIB of the current SNPN cell, obtains, according to an "on-broadcasting Indicator" in the master information block MIB, SNPN user subscription data loading (SNPN on-broadcasting) supported by the current SNPN cell, and then, may access the current SNPN cell, thereby obtaining the SNPN user subscription data remotely through the current SNPN cell.

For example, if the network side carries the first indication message through the downlink control information on the physical downlink control channel when sending the first indication message, the terminal indicates whether the SNPN supports SNPN user subscription data loading (SNPN associating) by reading the downlink control information on the physical downlink control channel, so as to select an associating SNPN cell.

Specifically, first, the UE triggers a process of selecting an on-addressing SNPN cell, then after the UE synchronizes to the current SNPN cell, the UE starts to monitor a PDCCH (Physical Downlink Control Channel) and parse DCI (Downlink Control Information), obtains, according to the DCI, SNPN user subscription data loading (SNPN on-addressing) supported by the current SNPN cell, and then the terminal may access the current SNPN cell, thereby remotely obtaining the SNPN user subscription data through the current SNPN cell.

Specifically, the network side may further send second indication information to the terminal, and after the terminal resides in an enhancing SNPN cell, the terminal triggers measurement on an adjacent cell along with a change in signal quality of a serving cell, so that the terminal needs to obtain whether or not an SNPN adjacent cell of the current SNPN cell supports SNPN user subscription data loading (SNPN enhancing) according to the second indication information.

And if the terminal determines that the SNPN adjacent cell of the current SNPN cell supports the loading of the SNPN user subscription data according to the second indication information, triggering the measurement of the adjacent cell, and evaluating whether the adjacent cell is reselected so as to realize that other SNPN cells supporting the loading of the SNPN user subscription data (SNPN associating) are reselected during cell reselection.

For example, when the network side sends the second indication message, the second indication message may be carried by a system message SIB3 or SIB4, and the terminal reselects another onboarding SNPN cell according to the second indication message indicating whether the SNPN neighbor cell of the current SNPN cell in the system message, for example, SIB3 or SIB4, supports loading of the SNPN user subscription data.

Specifically, after the terminal resides in an uplink SNPN cell, the terminal triggers measurement of an adjacent cell along with the change of the signal quality of the serving cell, then the network side indicates, through an "uplink Indicator" in the system message SIB3, that the SNPN adjacent cell of the current SNPN cell of the terminal supports SNPN user subscription data loading (SNPN uplink), and the terminal takes the SNPN adjacent cell as a candidate cell for cell reselection, measures the adjacent cell, and evaluates whether to reselect the adjacent cell.

and sending third indication information to the terminal equipment, wherein the third indication information comprises a terminal equipment list which is allowed to be accessed and used for carrying out SNPN user subscription data loading.

Specifically, after the network side sends the first indication information to the terminal and enables the terminal to determine that the current SNPN cell supports loading of SNPN user subscription data (SNPN associating) according to the first indication information, or after the terminal sends the second indication information and enables the terminal to determine that the SNPN neighbor cell of the current SNPN cell supports loading of SNPN user subscription data according to the second indication information, the network side can also send the third indication information to the terminal and enable the terminal to determine a terminal device list which is allowed to be accessed by the current SNPN cell and used for loading of the SNPN user subscription data according to the third indication information.

It can be understood that, the network side adds a function of indicating, in the third indication information, a list of terminal devices that are allowed to access and that perform loading of SNPN subscriber subscription data.

For example, after the terminal triggers the process of selecting the uplink SNPN cell and synchronizes to the target cell, the network side sends first indication information to the terminal; enabling the terminal to determine that the current SNPN cell supports the loading of the SNPN user subscription data by using an 'associating _ Indicator' in the first indication message according to the first indication message; further checking third indication information sent by the network side, and determining whether the terminal is matched with a device list in the third indication information according to the device list supported by the current SNPN cell indicated by the third indication information by 'supported _ DeviceList'; and if the terminal is determined to be in the device list supported by the current SNPN cell indicated by the third indication information, the terminal is accessed to the current SNPN cell, and the SNPN user subscription data is remotely acquired through the current SNPN cell.

For example, after a terminal camps on an enhancing SNPN cell, the terminal triggers measurement of neighboring cells along with the change of signal quality of a serving cell; the network side sends a second indication message to the terminal, and then the terminal determines that the SNPN adjacent cell of the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to an 'associating Indicator' in the second indication message; if the SNPN adjacent cell does not support SNPN user subscription data loading, the SNPN adjacent cell is not used as a candidate cell for cell reselection; if the 'on-broadcasting _ Indicator' in the second indication information indicates that the SNPN adjacent cell supports the SNPN user subscription data loading, further checking third indication information sent by a network side, and determining that the terminal is matched with a device list supported by the SNPN adjacent cell according to the device list supported by the adjacent cell indicated by the 'supported _ DeviceList' in the third indication information; and if the terminal is determined to be in the device list supported by the adjacent cell indicated by the third indication information, taking the SNPN adjacent cell as a candidate cell for cell reselection, measuring the adjacent cell, and evaluating whether the adjacent cell is reselected.

Specifically, when the network side indicates which devices are allowed to access the network for SNPN subscriber subscription data loading (SNPN associating), any one of the following lists may be configured in a supported device list ("supported device list"):

list 1. List of supported device types;

list 2. List of supported device manufacturers;

list 3. List of supported device types and list of supported device vendors.

For example, a network side sends a first indication message to a terminal, so that the terminal triggers a process of selecting an enhancing SNPN cell, then the terminal acquires first indication information after synchronizing to a target cell, determines that "enhancing _ Indicator" of the first indication information indicates that the current SNPN cell supports SNPN user subscription data loading, further checks third indication information sent by the network side, and determines a list 1 device type list supported by the current SNPN cell according to the third indication information; and if the type of the terminal is one type in the list 1 device type list supported by the current SNPN cell indicated by the third indication information, residing in the current SNPN cell, and remotely acquiring the SNPN user subscription data through the current SNPN cell.

For example, the terminal triggers a process of selecting an uplink SNPN cell, then after the UE synchronizes to the current SNPN cell, the UE starts to monitor a PDCCH (Physical Downlink Control Channel) and analyzes a Downlink Control Information DCI (Downlink Control Information), obtains a subscription data loading (SNPN uplink) of the current SNPN cell supporting the SNPN user according to the Downlink Control Information DCI, then may further obtain a first indication Information carried by a Master Information Block (MIB) sent by the network side, and determines a device type list supported by the current SNPN cell according to the MIB; and if the type of the terminal is one of the device type lists supported by the current SNPN cell indicated by the MIB, the terminal resides in the current SNPN cell and remotely acquires the SNPN user subscription data through the current SNPN cell.

Specifically, the network side may receive, through the NG interface, fourth indication information indicating whether the access and mobility management function AMF sent by the core network supports SNPN user subscription data loading, and then use this information for AMF selection when the terminal accesses.

According to the SNPN cell access method provided by the embodiment of the invention, the terminal determines whether the current SNPN cell supports SNPN user subscription data loading according to the first indication information by sending the first indication information to the terminal, and after the current SNPN cell supports SNPN user subscription data loading, the terminal is accessed to the current SNPN cell to complete SNPN user subscription data loading, so that the problems that whether the SNPN cell is supported or not cannot be identified by the terminal in the prior art and the SNPN user subscription data loading of the terminal on the cell is allowed are solved, and the access flexibility and efficiency of the SNPN cell are improved.

Fig. 4 is a schematic flow chart of an access method of an SNPN cell according to another embodiment of the present invention; as shown in fig. 4, the method includes the steps of:

step 400, selecting a cell;

specifically, first, the terminal may trigger a process of selecting an uplink SNPN cell;

step 401, acquiring first indication information;

specifically, a network side sends a first indication message to a terminal, and the terminal can perform cell search after triggering a process of selecting an uplink SNPN cell, and acquire the first indication message sent by the network side after synchronizing to a target cell;

And if the first indication message is carried by the system message, the terminal reads the system information SIB1 of the current SNPN cell when acquiring the first indication message.

If the first indication message is carried by a Master Information Block MIB (Master Information Block), the terminal reads the Master Information Block MIB of the current SNPN cell when acquiring the first indication message.

If the first indication message is carried by downlink control information on the physical downlink control channel, the terminal monitors the PDCCH and analyzes the downlink control information on the physical downlink control channel when acquiring the first indication message.

Step 402, determining that the current SNPN cell supports SNPN user subscription data loading;

specifically, the terminal determines that an "associating _ Indicator" is used in the first indication information to indicate that the current SNPN cell supports loading of the subscription data of the SNPN user; if the current SNPN subdistrict does not support the SNPN user signing data loading, then the subdistrict selection is carried out again, and other subdistricts are selected;

step 403, determining that the terminal is matched with the device list in the third indication information;

specifically, if the first indication information indicates that the current SNPN cell supports loading of the SNPN user subscription data, the terminal further checks third indication information sent by the network side, and determines that the terminal matches with a device list in the third indication information according to the third indication information, where the third indication information is indicated by a supported _ deviceist device list supported by the current SNPN cell; if the terminal is not matched with the equipment list in the third indication information, cell selection is carried out again, and other cells are selected;

and step 404, accessing the current SNPN cell.

Specifically, if it is determined that the terminal is in the device list supported by the current SNPN cell indicated by the third indication information, the terminal is accessed to the current SNPN cell, and the SNPN user subscription data is remotely obtained through the current SNPN cell.

specifically, with the change of the signal quality of the serving cell, the terminal may trigger the UE to measure the neighboring cell according to a second indication message sent by the network side;

step 502, determining that the SNPN adjacent cell supports SNPN user subscription data loading;

specifically, the terminal determines that the SNPN neighboring cell of the current SNPN cell supports SNPN user subscription data loading (SNPN associating) according to an "associating Indicator" in the second indication information; if the SNPN adjacent cell does not support the loading of the SNPN user subscription data, the SNPN adjacent cell is not used as a candidate cell for cell reselection;

step 503, determining that the terminal is matched with a device list supported by the SNPN adjacent cell;

specifically, if the second indication information indicates that the SNPN neighbor cell supports the loading of the SNPN user subscription data by using an "associating _ Indicator", the third indication information sent by the network side is further checked, and the terminal is determined to be matched with the device list supported by the SNPN neighbor cell according to the device list supported by the neighbor cell indicated by the "supported _ deviceist" for the third indication information; if the terminal is not matched with the device list supported by the SNPN adjacent cell, the SNPN adjacent cell is not taken as a candidate cell for cell reselection;

and step 504, taking the SNPN adjacent cell as a candidate cell for cell reselection.

Specifically, if it is determined that the terminal is in the device list supported by the neighbor cell indicated by the third indication information "supported _ DeviceList", the SNPN neighbor cell is taken as a candidate cell for cell reselection, measurement on the neighbor cell is started, and whether the neighbor cell is reselected or not is evaluated.
