Abstract

The application provides a private network related historical information processing method and device, equipment and a storage medium. When a UE passes through a private network cell, the UE can record or not record UE historical information. If the UE records historical information, the UE acquires related information of the private network and saves the related information of the private network in the UE historical information. After the UE reports the historical information, the network side can understand the state of the UE and the state of the cell recorded by the UE through the related information of the private network, so as to facilitate the network side to perform network optimization processing and UE path prediction processing, or provide strong auxiliary parameters for UE path big data collection and analysis of the network side. In addition, if the UE accesses the private network cell and does not record the historical information, the UE historical information will not record the access condition of the UE to the public network at this time, thereby avoiding confusion of the network side.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network communication, and in particular to a private network related historical information processing method and device, equipment and a storage medium. BACKGROUND

[0002] In a new radio (NR) system, user equipment (UE) maintained UE historical information includes cell access records of the UE in an idle state, an inactive state and a connected state. A UE can save up to 16 UE historical information entries. The UE historical information can include related information of one or more cells accessed / resided by the UE, and each cell information is an independent entry.

[0003] In the current UE historical information record, only information related to the UE accessing a normal public land mobile network (PLMN) cell is provided, such as cell identification information of the public network, time information of the UE accessing the cell, and the like, to be used for network side statistics and prediction of the path and speed of the UE. However, if there is a private network cell on the path of the UE, the historical information recorded by different UE capabilities / private network mode UEs will also be different, which will cause confusion to the network side.

[0077] The specific embodiments of the present disclosure have been shown and described in the above drawings, and will be described in more detail hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure in any way, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0078] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0079] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a" and "the" used in the embodiments of the present application are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0080] It should be understood that the term "and / or" as used herein merely describes an associated relationship, that is, there can be three cases, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0081] Depending on the context, the word "if" as used herein can be interpreted as meaning "when" or "while" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if it is determined" or "if (a stated condition or event) is detected" can be interpreted as meaning "when it is determined" or "in response to determining" or "when (a stated condition or event) is detected" or "in response to detecting (a stated condition or event)".

[0082] It should also be noted that the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusions, so that a product or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or includes elements inherent to such product or system. Without more limitations, the element defined by the sentence "including a…" does not exclude the presence of another identical element in the product or system including the element.

[0083] At present, network types include Public Land Mobile Network (PLMN, referred to as public network) and Non-Public Network (NPN, referred to as private network).

[0084] Among them, the private network mainly includes two types: A) Stand-Alone Non-Public Networks (SNPN), which can be identified using PLMN ID+NID; B) Public Network Integrated NPN (PNI-NPN), which can be identified using PLMN ID+CAG ID.

[0085] The private network allows authorized part of the terminal equipment (User Equipment, UE) to access, and other UEs cannot access the private network. For example, when the authorized identification information of the private network exists in the subscription of the UE, the UE is allowed to access the network. After the UE accesses the private network, the network side will authenticate the UE to ensure that the UE is authorized by the private network.

[0086] For private network, UE can save UE private network mode information in addition to the UE capability of "whether to support private network" (private network capability), such as "only allow to work in private network" mode and "allow to work in public network" mode.

[0087] For example, for SNPN, the UE can be set to a dedicated access mode of SNPN Access Mode (SNPN AM), that is, the UE in SNPN AM open mode can only access SNPN network and cannot access public PLMN network; when the UE is set to SNPN AM closed mode, the UE can only access public PLMN network and cannot access SNPN network.

[0088] For example, for CAG, the UE can be configured with a CAG-only indicator and set to CAG-only open mode, that is, the UE in this mode can only access the cell in the allowed CAG list to be in a suitable cell; when the UE is set to CAG-only closed mode, the UE can access public PLMN network or PNI-NPN network in the allowed CAG list.

[0089] In addition, for network cells, when a cell only supports normal PLMN, the UE in SNPN AM mode is not allowed to access, and the UE with CAG capability but in CAG-only mode is not allowed to access;

[0090] When a cell only supports SNPN, that is, SNPN only cell, the UE without SNPN capability or with SNPN capability but not in SNPN AM mode is not allowed to access;

[0091] When a cell only supports CAG, that is, CAG only cell, the UE without CAG capability is not allowed to access.

[0092] In addition, one cell can be shared by one or more private networks and ordinary PLMNs. For example, telecom and unicom can share a cell (same frequency + PCI) and be distinguished by different PLMN IDs. Since a cell only broadcasts one set of system information, the PLMN list in the broadcast information needs to contain all shared networks, which can include different operators' PLMNs, equivalent PLMNs (EPLMNs), different types of private networks SNPN / CAG, etc. In a mixed scenario, a cell can have up to 12 entries, each of which can be a normal PLMN / SNPN / CAG, representing all network types and network identifiers in the same type that the cell can support.

[0093] In the NR system, the UE historical information maintained by the UE contains the cell access records of the UE in the idle state, inactive state and connected state. When the number of entries stored by the UE reaches the upper limit, each time a new entry is written, the oldest entry needs to be deleted first to ensure that the UE does not exceed the maximum number of entries.

[0094] The UE historical information can contain the relevant information of one or more cells in which the UE resides / accesses, and each cell information is an independent entry.

[0095] When the UE replaces the suitable cell, including entering other cells from the PCell (for the connected state) / serving cell (for the idle state / inactive state), or entering the no-service state 'any cell selection' from the 'camped normally' state, the UE records the information of the previous cell as follows: (1) the identification information of the cell: if the CGI of the previous PCell / serving cell is available, the CGI is recorded; otherwise, the cell is identified in the form of frequency + PCI; (2) the residence / access time length of the UE in the cell timeSpent.

[0096] When the UE enters the 'camped normally' state and was previously in the 'any cell selection' state or the 'camped on any cell' state, the UE records the information as follows: (1) only the duration information timeSpent in the 'any cell selection' state or the 'camped on any cell' state is contained in one entry, but no specific cell information is recorded.

[0097] The UE can indicate and report to the network side after having the ability to store the UE historical information and after saving the UE historical information. In the RRC (connection) establishment process or the RRC (connection) recovery process, the UE can report a 1-bit indication information. After the network receives the indication, the UE can be notified to report and receive the specific historical information content of the UE using the UEInformationRequest / Response message.

[0098] For example, Figure 1 The application scenario of the technical solution of the present application is shown in FIG. 1. Figure 1 As shown in FIG. 1, for the UE historical information recorded by UE1, the cell A, cell B and cell C are all public network cells, and UE1 has the public network access capability, so the UE historical information contains the information of each cell and the access time of the UE.

[0099] The current UE historical information records only provide information related to the UE's access to cells in the normal PLMN, such as the public network cell identifier and the time the UE accessed the cell. This information is used by the network side to statistically analyze and predict the UE's path and speed. Figure 1 The UE historical information recorded is all from public network cells. However, if the UE's path also includes CAG-only or SNPN-only cells, the historical information recorded by UEs with different capabilities / private network modes will differ, causing confusion on the network side.

[0100] For example, if an SNPN AM mode UE leaves the coverage area of ​​its subscribed SNPN, it will be unable to camp / access normally, even if there is currently normal PLMN coverage. In this case, the UE's UE / mobility history information will record the "No suitable cell information" branch for the time when it was in the normal PLMN, only recording the duration of the "No suitable cell information" state. Furthermore, because the UE's NPN support capabilities are not known to the network, and NPN-related information (capabilities, NPN mode) is not reported when reporting historical information, the network may misjudge the path traversed by the UE.

[0101] For example, if a CAG-only mode UE leaves the coverage area of ​​its subscribed CAG, it will be unable to camp / access normally, even if there is normal PLMN coverage. In this case, the UE's UE / mobility history information will record the "no suitable cell information" branch for the time when it was in a normal PLMN, only recording the duration of the "no suitable cell information" state. Furthermore, since the UE's NPN support capabilities are not known to the network, and NPN-related information (capabilities, NPN mode) is not reported when reporting historical information, the network may misjudge the path traversed by the UE.

[0102] Specifically, Figure 2 This is a schematic diagram illustrating another application scenario of the technical solution of this application, such as... Figure 2 As shown, Figure 2 UE2 and Figure 1 UE1 has the same geographical movement path as UE2, which also passes through cell A, cell B and cell C. UE2 has private network capability. However, when UE2 passes through cell C, if UE2 switches to SNPN AM enabled mode or CAG-only enabled mode, UE2 cannot access cell C. Therefore, UE2 records "no suitable cell information" for cell C.

[0103] After receiving the UE history information of UE1 and UE2, the network device finds that the UE history information of UE1 and UE2 is not the same, which may lead the network device to judge that the moving paths of UE1 and UE2 are inconsistent, but in fact, the moving paths of UE1 and UE2 are the same, thereby causing the network device to make a wrong judgment. Although the network side can obtain the support of each cell for NPN through query messages between nodes, it is necessary to query each node for which the UE reports the history information one by one, which will consume a large amount of network signaling overhead, and the network device cannot know the support capability of each NPN and the NPN mode in which the UE records.

[0104] Therefore, the existing UE history information recording method has certain defects.

[0105] The private network related history information processing method provided in the present application aims to solve the above technical problems in the prior art.

[0106] The main idea of the present application is that when a UE passes through a private network cell, the UE can choose whether to record UE history information, wherein if the UE records history information, the UE acquires related information of the private network and saves the related information of the private network in the UE history information; after the UE reports the history information, the network side can understand the state of the UE and the state of the cell recorded by the UE through the related information of the private network, so as to facilitate the network side to perform network optimization processing and UE path prediction processing, or to provide strong auxiliary parameters for UE path big data collection and analysis of the network side. In addition, if the UE accesses a private network cell and does not record history information, the UE history information will not record the access situation of the UE to the public network at this time, thereby avoiding confusion of the network side.

[0107] Specifically, in the present application, in order to facilitate the network side to better perform network optimization, UE path prediction or avoid confusion of the network side, one or more of the following ways can be used:

[0108] (1) When the access / residence cell of the UE with NPN capability is in a private network registration state, stop recording the UE history information; or when the UE accesses an NPN only cell, stop recording the UE history information;

[0109] Therefore, the UE can avoid confusion of the network side by not recording history information.

[0110] (2) Carry the current private network related information in the history information of the UE with NPN capability, including one or more of the following:

[0111] a. Simple indication information that the UE accesses a private network cell;

[0112] b. Cell identity or label of the access cell being SNPN / CAG only;

[0113] c. Cell identity or label of the access cell being SNPN / CAG and normal PLMN shared;

[0114] d. SNPN / CAG capability / mode of the UE;

[0115] (3) In the absence of historical information of the UE without NPN capability / NPN mode off, or in the case that the UE has NPN capability but the NPN identity broadcasted by the network cell does not match the NPN identity to which the UE is subscribed (i.e. the UE does not have private network access permission), the current private network related information is carried in the historical information of the UE, including one or more of the following:

[0116] a. Simple indication information that the cell private network cannot be accessed;

[0117] b. Whether there is an NPN cell signal and signal strength when the UE is in the 'any cell selection' out-of-service state;

[0118] c. Current NPN cell identity and signal strength when the UE is in the 'camped on any cell' any cell camping state;

[0119] d. Whether there is an NPN cell signal and cell identity / signal strength when the UE normally records suitable normal cell information;

[0120] e. SNPN / CAG capability / mode of the UE;

[0121] Therefore, the network side can comprehensively understand the state of the UE and the state of the cell recorded by the UE through the above private network related information, facilitating network optimization processing and UE path prediction processing.

[0122] It can be understood that the processing steps of the private network related historical information processing method in the present application can be implemented by a terminal device.

[0123] The terminal device can be a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and / or other data connectivity to a user, a hand-held device having a wireless connection function, or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile telephone (also known as a "cellular" telephone) and a computer with a mobile termination, for example, which can be portable, pocket, hand-held, computer-embedded, or vehicle-mounted, and exchanges voice and / or data with the RAN. The wireless terminal can also be a Personal Communication Service (PCS) telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and the like. The wireless terminal can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment, without limitation. Optionally, the terminal device can also be a smart watch, a tablet computer, and the like.

[0124] In addition, the network device involved in the present application can be a base station, specifically, a base station (BTS) and / or a base station controller in a Global System of Mobile communication (GSM) or a Code Division Multiple Access (CDMA), can be a base station (NodeB, NB) and / or a radio network controller (RNC) in a Wideband Code Division Multiple Access (WCDMA), can be an evolved base station (eNB or eNodeB) in a Long Term Evolution (LTE), or a relay station or an access point, or a base station (gNB) in a 5G network, or a base station in a future 6G network, and the like, which are not limited herein.

[0125] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0126] In some embodiments, for the scenario of recording UE history information of a terminal device, a private network related history information processing method is provided and applied to the terminal device.

[0127] Figure 3 The schematic diagram of the private network related history information processing method provided by the embodiments of the present application is shown in FIG. 1, which mainly includes the following steps: Figure 3

[0128] S310, determining that the terminal device is in the signal coverage range of a private network cell, and acquiring the related information of the private network;

[0129] When the UE determines that it is currently located in the coverage range of the private network cell, the UE can acquire the private network related information corresponding to the cell by reading the system information block 1 (SIB1) information broadcast by the private network cell.

[0130] S320, recording terminal device history information, the terminal device history information including the related information of the private network;

[0131] ​After obtaining the private network related information, the UE records the private network related information in the terminal device history information when recording terminal device history information, so as to facilitate subsequent reporting to the network device.

[0132] S330, reporting the terminal device history information to the network device.

[0133] When the UE receives the reporting indication information of the network device, if the network device uses the UEInformationRequest / Response message to indicate the UE, the UE reports the terminal device history information recorded by itself to the network device, so that the network device knows the private network related information.

[0134] The embodiment provides a private network related history information processing method. The UE first obtains private network related information and saves the private network related information in the UE history information. After the UE reports the history information, the network side can know the state of the UE and the state of the cell recorded by the UE through the private network related information, so as to facilitate the network side to perform network optimization processing and UE path prediction processing, or provide strong auxiliary parameters for UE path big data collection and analysis of the network side.

[0135] In some embodiments, recording the terminal device history information comprises: when the terminal device accesses a private network cell, recording terminal device history information containing first private network related information.

[0136] Optionally, the first private network related information comprises at least one of the following:

[0137] first indication information for indicating that the terminal device accesses the private network cell;

[0138] at least one of the following: a cell identifier of the cell accessed by the terminal device, a private network type identifier, and a signal strength;

[0139] a private network capability and / or a private network mode of the terminal device.

[0140] Specifically, when the terminal device accesses the private network cell, recording the terminal device history information containing the first private network related information mainly includes the following cases:

[0141] (1) when the terminal device is in an independent private network dedicated access SNPN AM enabled mode, and accesses a terminal device subscription only independent private network SNPN only cell, or accesses an independent private network SNPN and public network / integrated private network CAG shared cell subscribed by the terminal device, recording the terminal device history information containing the first private network related information;

[0142] When the UE is in SNPN AM on mode, only allow normal camping and access in SNPN cell that the UE subscribes to, i.e. the condition for UE normal camping / access is: when the cell is SNPN only cell or SNPN and normal PLMN / CAG shared cell, and the cell broadcasts the SNPN that the UE subscribes to. For explicit indication of private network related information, when the UE wants to access / camp to a cell, it needs to read the SIB1 to know whether the current SNPN is supported by the cell. From the SIB1, the UE can also know the CGI information of the current cell.

[0143] If the current cell is SNPN only cell or SNPN and normal PLMN / CAG shared cell, and the SNPN that the UE subscribes to is in the SNPN list broadcast by the current cell, the UE in SNPN AM mode can normally camp / access in the current cell through the private network. In order to distinguish from the UE without NPN capability, at least one of the following information can be carried in the UE history information record:

[0144] - simple indication information that the accessed cell is a private network;

[0145] - cell identification or label of the SNPN only cell that the accessed cell is;

[0146] - cell identification or label of the SNPN and normal PLMN / CAG shared cell that the accessed cell is;

[0147] - SNPN capability / mode information (SNPN AM on mode) of the UE.

[0148] (2) When the terminal device is in a CAG only on mode that only supports a public network integrated private network and accesses a CAG only cell that only supports a public network integrated private network to which the terminal device subscribes, or accesses a CAG and public network / SNPN shared cell to which the terminal device subscribes, record the terminal device history information containing the first private network related information;

[0149] When the UE is in CAG-only on mode, only allow normal camping and access in CAG cell that the UE subscribes to. I.e. the condition for UE normal camping / access is: when the cell is CAG only cell or CAG and normal PLMN / SNPN shared cell, and the cell broadcasts the CAG that the UE subscribes to.

[0150] If the current cell is a CAG only cell or a CAG and normal PLMN / SNPN shared cell, and the CAG the UE subscribes to is in the CAG list broadcast by the current cell, the CAG only mode UE can normally camp / access in the current cell through the private network. In order to distinguish from the UE without NPN capability, the following information can be carried in the UE history information record:

[0151] - simple indication information that the accessed cell is a private network;

[0152] - cell identification or label of the CAG only cell;

[0153] - cell identification or label of the CAG and normal PLMN / SNPN shared cell;

[0154] - CAG capability / mode information of the UE (CAG only open mode).

[0155] (3) When the terminal device is in the CAG only closed mode, and accesses the CAG only cell to which the terminal device subscribes, or accesses the CAG and public network / SNPN shared cell to which the terminal device subscribes, record the terminal device history information containing the first private network related information.

[0156] The CAG only closed mode UE can access the normal PLMN and can access the CAG network to which the UE subscribes. Then compared with the UE without NPN capability: when a certain cell only supports normal PLMN or CAG and normal PLMN sharing, whether the UE supports CAG or not, it can access the cell; when a certain cell is CAG only, the UE can read the SIB1 information of the cell, and when the CAG in the SIB1 has the subscription CAG of the UE, it can camp / access the cell.

[0157] In order to distinguish from the UE without NPN capability, the following information can be carried in the UE history information record:

[0158] - simple indication information that the accessed cell is a private network;

[0159] - cell identification or label of the CAG only cell;

[0160] - cell identification or label of the CAG and normal PLMN / SNPN shared cell;

[0161] - CAG capability / mode information of the UE (CAG only closed mode).

[0162] Thus, after the UE reports the historical information, the network side can understand the state of the UE and the state of the cell recorded by the UE through the private network related information, so as to facilitate the network optimization processing and the UE path prediction processing of the network side, or provide strong auxiliary parameters for the network side UE path big data collection and analysis.

[0163] In some embodiments, the terminal device historical information is recorded, including: when the terminal device does not access the private network cell, recording the terminal device historical information containing the second private network related information.

[0164] Optionally, the second private network related information includes at least one of the following:

[0165] Second indication information for indicating that the terminal device does not access the private network cell;

[0166] At least one of the following: cell identifier, private network type identifier and signal strength of the cell in which the terminal device does not access;

[0167] Private network capability and / or private network mode of the terminal device.

[0168] Specifically, when the terminal device does not access the private network cell, the terminal device historical information containing the second private network related information is recorded, mainly including the following several cases:

[0169] (1) When the terminal device is in the SNPN AM enabled mode, the private network cell is the SNPN only cell or the shared cell of SNPN and public network / CAG, and the SNPN to which the terminal device subscribes is outside the SNPN list broadcast in the private network cell, the terminal device historical information containing the second private network related information is recorded;

[0170] When the UE is in the SNPN AM enabled mode, only the SNPN cell to which the UE subscribes is allowed to normally camp and access, that is, the normal camping / access condition of the UE is that: when the cell is the SNPN only cell or the shared cell of SNPN and normal PLMN / CAG, and the cell broadcast contains the SNPN to which the UE subscribes.

[0171] If the current cell is a normal PLMN cell, or the current cell is a SNPN / normal PLMN shared cell, and the SNPN to which the UE subscribes is outside the SNPN list broadcast in the current cell, the UE in the SNPN AM mode cannot normally camp / access. In order to optimize the network decision, at least one of the following information can be carried in the UE historical information record:

[0172] Simple indication information that the private network of the cell cannot be accessed;

[0173] - The access cell is a SNPN shared cell with normal PLMN / CAG;

[0174] - Whether there is a NPN cell signal and signal strength when the UE is in the state of 'any cell selection';

[0175] - The current NPN cell identity and signal strength when the UE is in the state of 'camped on any cell'.

[0176] If the current cell is a SNPN only cell or a SNPN shared cell with normal PLMN / CAG, and the SNPN to which the UE is subscribed is not in the SNPN list broadcast by the current cell, the UE in SNPN AM mode cannot normally camp / access. In order to optimize the network decision, the following information can be carried in the UE history information record:

[0177] - Simple indication information that the private network of the cell cannot be accessed;

[0178] - Cell identity or label of the SNPN only cell;

[0179] - Whether there is a NPN cell signal and signal strength when the UE is in the state of 'any cell selection';

[0180] - The current NPN cell identity and signal strength when the UE is in the state of 'camped on any cell'.

[0181] - SNPN capability / mode information of the UE (SNPN AM on mode).

[0182] (2) When the terminal device is in the SNPN AM off mode and the private cell is a SNPN only cell, record the terminal device history information containing the second private network related information; or

[0183] If the current cell is a SNPN only cell, but the terminal device is in the SNPN AM off mode, the UE in the SNPN AM off mode cannot normally camp / access. In order to optimize the network decision, the following information can be carried in the UE history information record:

[0184] - Simple indication information that the private network of the cell cannot be accessed;

[0185] - Cell identity or label of the SNPN only cell;

[0186] - Whether there is an NPN cell signal and signal strength when the UE is in the no service state 'any cell selection';

[0187] - The current NPN cell identity and signal strength when the UE is in the any cell camped state 'camped on any cell';

[0188] - SNPN capability / mode information of the UE (SNPN AM off mode).

[0189] (3) When the terminal device is in the CAG only on mode, the private network cell is a CAG only cell or a shared cell of CAG and public network / SNPN, and the CAG to which the terminal device is subscribed is not in the CAG list broadcast by the private network cell, record the terminal device historical information containing the second private network related information;

[0190] When the UE is in the CAG-only on mode, only the CAG cell to which the UE is subscribed is allowed to normally camp and access. That is, the condition for the UE to normally camp / access is that when the cell is a CAG only cell or a shared cell of CAG and normal PLMN / SNPN, and the CAG of the UE is included in the CAG list broadcast by the cell.

[0191] If the current cell is a normal PLMN cell, or the current cell is a shared cell of CAG / normal PLMN, and the CAG to which the UE is subscribed is not in the CAG list broadcast by the current cell, the UE in the CAG-only mode cannot normally camp / access. In order to optimize the network decision, the following information can be carried in the UE historical information record:

[0192] - Simple indication information that the private network of the cell cannot be accessed;

[0193] - The identity or label of the cell being a shared cell of CAG and normal PLMN / SNPN;

[0194] - Whether there is an NPN cell signal and signal strength when the UE is in the no service state 'any cell selection';

[0195] - The current NPN cell identity and signal strength when the UE is in the any cell camped state 'camped on any cell'.

[0196] If the current cell is a CAG only cell or a shared cell of CAG and normal PLMN / SNPN, and the CAG to which the UE is subscribed is not in the CAG list broadcast by the current cell, the UE in CAG only mode cannot normally camp on / access. In order to optimize the network decision, the following information can be carried in the UE history information record:

[0197] - simple indication information that the cell private network cannot be accessed;

[0198] - cell identification or label of the CAG only cell;

[0199] - whether there is a NPN cell signal and signal strength when the UE is in the no service state 'any cell selection';

[0200] - current NPN cell identification and signal strength when the UE is in the any cell camped state 'camped on any cell';

[0201] - CAG capability / mode information of the UE (CAG only open mode).

[0202] (4) When the terminal device is in the CAG only closed mode, the private network cell is a CAG only cell, and the CAG to which the terminal device is subscribed is not in the CAG list broadcast by the private network cell, record the terminal device history information containing the second private network related information;

[0203] The UE in the CAG only closed mode can access the normal PLMN and can access the CAG network to which the UE is subscribed.

[0204] When a certain cell is CAG only, the UE can read the SIB1 information of the cell, and when the CAG in the SIB1 does not have the subscription CAG of the UE, the UE cannot camp on / access the cell.

[0205] In order to distinguish from the UE without NPN capability, the following information can be carried in the UE history information record:

[0206] - simple indication information that the cell private network cannot be accessed;

[0207] - cell identification or label of the CAG only cell;

[0208] - whether there is a NPN cell signal and signal strength when the UE is in the no service state 'any cell selection';

[0209] - Current NPN cell identity and signal strength when the UE is in any cell camped state 'camped on any cell'.

[0210] - CAG capability / mode information of the UE (CAG only off mode).

[0211] (5) When the terminal device does not have private network access capability, and the private network cell is a CAG only cell, a SNPN only cell, or a shared cell of at least two of SNPN, CAG, and public network, record the terminal device history information containing the second private network related information.

[0212] For the UE without NPN capability, only the cell supporting normal PLMN can be accessed, and for such UE, when passing through the CAG only cell, the SNPN only cell, or the shared cell of at least two of SNPN, CAG, and public network, the NPN identifier list information in the SIB1 information broadcast by the cell is read to confirm that the UE cannot access / reside in the cell.

[0213] Therefore, after the UE reports the history information, the network side can understand the state of the UE and the state of the cell recorded by the UE through the related information of the private network, which facilitates the network optimization processing and UE path prediction processing of the network side, or provides strong auxiliary parameters for the network side UE path big data collection and analysis. In addition, the network device can also distinguish various types of private network cells on the UE path without querying the cell, thereby saving network signaling overhead.

[0214] In some embodiments, another private network related history information processing method is provided for the scenario that the terminal device does not record the UE history information, and is applied to the terminal device.

[0215] Figure 4 Another schematic diagram of the private network related history information processing method provided by the embodiments of the present application is shown in Figure 4 The method mainly includes the following steps:

[0216] S410, when the terminal device accesses the public network cell, record the terminal device history information;

[0217] S420, when the terminal device accesses the private network cell, stop recording the terminal device history information;

[0218] S430, report the terminal device history information to the network device.

[0219] Specifically, when the terminal device accesses the private network cell, stop recording the terminal device history information, which mainly includes the following several cases:

[0220] (1) When the terminal device is in the SNPN AM on mode, and accesses the SNPN only cell subscribed by the terminal device, or accesses the SNPN shared with the public network / CAG cell subscribed by the terminal device, stop recording the terminal device historical information;

[0221] When the UE is in the SNPN AM on mode, only the SNPN cell subscribed by the UE is allowed to normally camp and access, that is, the normal camping / access condition of the UE is that: when the cell is an SNPN only cell or an SNPN shared with normal PLMN / CAG cell, and the cell broadcast contains the SNPN subscribed by the UE.

[0222] At this time, if the UE accesses the above cell, the recording of the terminal device historical information can be stopped, that is, the cell access information of the terminal device historical information can be empty.

[0223] (2) When the terminal device is in the CAG only on mode, and accesses the CAG only cell subscribed by the terminal device, or accesses the CAG shared with the public network / SNPN cell subscribed by the terminal device, stop recording the terminal device historical information;

[0224] When the UE is in the CAG-only on mode, only the CAG cell subscribed by the UE is allowed to normally camp and access. That is, the normal camping / access condition of the UE is that: when the cell is a CAG only cell or a CAG shared with normal PLMN / SNPN cell, and the cell broadcast contains the CAG subscribed by the UE.

[0225] At this time, if the UE accesses the above cell, the recording of the terminal device historical information can be stopped, that is, the cell access information of the terminal device historical information can be empty.

[0226] (3) When the terminal device is in the CAG only off mode, and accesses the CAG only cell subscribed by the terminal device, or accesses the CAG shared with the public network / SNPN cell subscribed by the terminal device, stop recording the terminal device historical information.

[0227] The UE in the CAG only off mode can access the normal PLMN, and can also access the CAG network subscribed by the UE.

[0228] At this time, if the UE accesses the above cell, the recording of the terminal device historical information can be stopped, that is, the cell access information of the terminal device historical information can be empty.

[0229] The embodiment provides a private network related historical information processing method. If a UE accesses a private network cell, the UE can not record historical information, and thus UE historical information does not record the access condition of the UE to a public network at this time, thereby avoiding confusion of a network side.

[0230] It should be understood that, although each step in the flowchart in the above embodiment is shown in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and they can be executed in other sequences. Moreover, at least part of the steps in the figure can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence is not necessarily sequential, but can be alternately executed with at least part of other steps or sub-steps or stages of other steps.
