Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to an information processing method and apparatus, communication equipment and storage medium. Background Technology

[0002] After a User Equipment (UE) powers on, it needs to register with the network. Typically, the UE may also periodically update its registration. The base station broadcasts one or more Tracking Area Identifiers (TAIs). During the initial access process, the UE sends a registration request message to the network. Upon receiving the UE's registration request message, the base station sends the broadcast TAI along with the registration request message to the Access Management Function (AMF). If the base station knows the UE's current TA, it will send the TAI of that TA to the AMF. After receiving the TAI, the AMF can construct a Registration Area (RA) for the UE based on the received TAI. Summary of the Invention

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of the present invention.

[0046] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments disclosed herein. The singular forms “a,” “the,” and “the” used herein are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0047] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0048] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

[0049] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0050] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0051] The access device 12 can be an evolved NB (eNB) used in a 4G system; or, the access device 12 can be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0052] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0053] Figure 2 The diagram illustrates a UE registration and update process, which may specifically include:

[0054] 1) The UE sends a registration request message to the Radio Access Network (RAN). The registration request message may include parameters such as: registration type, Subscription Concealed Identifier (SUCI) or 5G Globally Unique Temporary Identity (GUTI) or Permanent Equipment Identifier (PEI), Requested Network Slice Selection Assistance Information (NSSAI), and Last Accessed Tracking Area Identifier (TAI).

[0055] UE registration types include initial registration, mobile registration update, periodic registration update, and emergency registration. The last accessed TAI may be included in the registration request new message to help the Access Management Function (AMF) designate the Registration Area (RA) for the UE.

[0056] 2) AMF selection may include: (R)AN selecting an AMF based on the radio access technology or access technology ((R)AT) and requesting NSSAI. If (R)AN cannot select a suitable AMF, it will forward the registration request message to the AMF configured in (R)AN.

[0057] 3)(R)AN sends a registration request to the new AMF, for example, by sending an N2 message. This message contains N2 parameters, the registration request, etc. The N2 parameters include the selected Public Land Mobile Network (PLMN) Identification ID, location information, and the cell identifier associated with the cell where the UE is camped.

[0058] 4) Context Transfer (Namf_UEContext Transfer).

[0059] 5) If the AMF of the service has changed since the last registration, the new AMF can retrieve the stored UE Subscriber Permanent Identifier (SUPI) and UE context from the old AMF. If the UE does not provide a SUPI and does not obtain it from the old AMF, the new AMF initiates an identity request procedure to the UE to request a SUPI.

[0060] 6) The new AMF may decide to initiate UE authentication by invoking the Authentication Server Function (AUSF). The AMF selects ASF based on SUPI or SUCI.

[0061] 7) If the AMF has changed since the last registration, or if the UE provides a SUPI that does not reference a valid context in the AMF, then the AMF will select a UDM based on the SUPI and register with the UDM. If the AMF does not have the UE's subscription data, the AMF will retrieve access, mobile subscription, and other data from the UDM.

[0062] 8) The new AMF establishes / modifies the AM Policy association with the PCF.

[0063] 9) If the registration request in step 1 contains a list of PDU sessions to be activated, the AMF will send a session update request (Nsmf_PDUSession_UpdateSMContext request) to the SMF associated with the PDU session to activate the user plane (UP) connection of these PDU sessions.

[0064] 10) The new AMF sends a registration acceptance message to the UE, indicating that the registration request has been accepted. This registration acceptance message includes the registration area, mobility restrictions, NSSAI permission, and strict timed registration timer indication.

[0065] If the AMF assigns a new registration area, the AM will send the new registration area to the UE. If the registration acceptance message does not contain registration area information, the UE considers the old registration area to be valid.

[0066] If mobility restrictions apply to the UE and the registration type is not emergency registration, then mobility restrictions are included.

[0067] like Figure 3 As shown, this disclosure provides an information processing method, which is executed by a first network element. The method includes:

[0068] S1110: Obtain trusted location information of the user equipment (UE);

[0069] S1120: Send the trusted location information to the second network element or the UE.

[0070] The first network element can be any core network element; for example, the first network element includes, but is not limited to, AMF.

[0071] The second network element can be various access network elements. For example, the second network element may include, but is not limited to, an eNB or a gNB.

[0072] Assuming the first network element is an AMF and the second network element is a base station, the trusted location information is sent to the base station using an N2 message or an NGAP message.

[0073] Assuming the first network element is an AMF, a trusted location information can be sent to the UE using a NAS message.

[0074] The trusted location information can be location information that indicates the location of the UE and is trusted by the core network.

[0075] For example, the trusted location information includes, but is not limited to, location information obtained by locating the UE using a communication network containing the first network element.

[0076] After the trusted location information is sent by the first network element to the second network element or the UE, the UE and / or the second network element can use the trusted location information to perform operations related to the UE's location.

[0077] In some embodiments, the trusted location information of the UE is:

[0078] The first network element obtains the UE's location information based on the Location Service (LCS) program;

[0079] or,

[0080] The location information of the UE verified by the network.

[0081] In this embodiment of the disclosure, the UE's trusted location information can be the UE's location information obtained according to the LCS program. The UE's location information obtained using the LCS program can be obtained using a network-based location measurement and calculation method, which can make the UE's location information obtained based on the positioning method trusted.

[0082] In other embodiments, the trusted location information may also be location information verified by the network including the first network element. If the location information has been verified by the first network element, it is considered trusted location information. For example, the first network element may verify the UE's location information according to operational policies, and consider it trusted if it has been verified.

[0083] In some embodiments, the trusted location information includes at least one of the following:

[0084] The satellite positioning information that identifies the UE;

[0085] The Tracking Area Identifier (TAI) of the UE is located in;

[0086] The cell identifier that identifies the cell where the UE is located;

[0087] The base station identifier that identifies the base station to which the UE is connected.

[0088] The satellite positioning information may include: location information obtained based on the satellite positioning system, which includes, but is not limited to: latitude and longitude information.

[0089] The TAI that identifies the tracking area where the UE is located can be determined based on the TA to which the UE is currently located.

[0090] like Figure 4 As shown, this disclosure provides an information processing method, executed by a first network element, the method further comprising:

[0091] S1210: Obtain trusted location information of the user equipment (UE);

[0092] S1220: Based on the UE's trusted location information, determine whether to allow the UE to access the PLMN to which the first network element belongs or to deny the UE access to the PLMN to which the first network element belongs;

[0093] S1230: Send the trusted location information to the second network element or the UE.

[0094] This embodiment can be implemented alone or in combination with the foregoing embodiments.

[0095] If the PLMN access request of the UE is determined based on the UE's trusted location information, then the erroneous access denial or access permission caused by controlling the UE access to the PLMN based on untrusted location information can be reduced, thereby improving the precision control of UE access.

[0096] For example, a UE located in a border region between country A and country B uses satellite access. The UE, belonging to country A, selects to access the network of an operator in country B. The network equipment of the operator in country B determines that the UE's current location is in country A, and according to the laws of country B, the UE is prohibited from accessing the network in its current location using a non-roaming method.

[0097] For example, the trusted location information may be carried in a registration acceptance message sent to the UE and sent to the second network element or the UE.

[0098] like Figure 5 As shown, this disclosure provides an information processing method, which is executed by a first network element. The method includes:

[0099] S1310: Obtain trusted location information of the user equipment (UE);

[0100] S1320: Send the trusted location information to the second network element or the UE.

[0101] S1330: Based on the UE's trusted location information, determine the UE's Registration Area (RA), Forbidden Area (FA), and / or Service Area Restriction (SAR).

[0102] This embodiment can be executed alone or in combination with the aforementioned embodiments. In addition, in this embodiment, there is no fixed order between S1320 and S1330. S1320 can be executed first and then S1330, or S1330 can be executed first and then S1320; or S1320 and S1330 can be executed simultaneously.

[0103] An RA may include one or more TAs; an RA can be used to page a UE. An FA may include one or more TAs that block UE access.

[0104] SAR may include: one or more TAs that allow UE access, and / or one or more TAs that restrict UE access.

[0105] After determining the RA, FA, or SAR information, the first network element will send it to the corresponding UE, which will then facilitate the UE to perform network access and / or registration updates based on its own location and the RA, FA, and / or SAR information.

[0106] In this embodiment of the disclosure, since the first network element sends the UE's trusted location information to the UE in S1320, the UE will receive the trusted location information authenticated by the network side. The UE will also receive the RA, FA, and SAR constructed by the first network element.

[0107] In another embodiment, an information processing method is provided, which can be executed by a first network element, the method comprising:

[0108] S1310: Obtain trusted location information of the user equipment (UE);

[0109] S1330: Based on the UE's trusted location information, determine the UE's Registration Area (RA), Forbidden Area (FA), and / or Service Area Restriction (SAR).

[0110] That is, the trusted location information of the UE determined by the first network element is not sent to the UE or the second network element. The UE or the second network element can also obtain the trusted location information of the UE from other network elements, for example, by receiving the trusted location information of the UE from the Location Management Function (LMF).

[0111] Of course, this embodiment can be implemented alone or in combination with the foregoing embodiments.

[0112] like Figure 6 As shown, this disclosure provides an information processing method, which is executed by a first network element. The method includes:

[0113] S1410: Obtain trusted location information of the user equipment (UE);

[0114] S1420: Determine the paging area of ​​the paging UE based on the UE's trusted location information.

[0115] This embodiment can be implemented alone or in combination with the foregoing embodiments. If the paging area of ​​the UE is determined based on reliable location information, paging failures caused by inaccurate paging ranges can be reduced, thus improving the paging success rate.

[0116] The paging area may include one or more TAs.

[0117] For example, after a UE enters the idle state, if the network side needs to send data to the UE, it can page the UE through a paging message. After receiving the paging message, the paged UE will exit the idle state and switch to the connected state. After the UE switches to the connected state, the network side can send data to the UE through the network connection.

[0118] like Figure 7 As shown, this disclosure provides an information processing method, executed by a second network element, the method comprising:

[0119] S2110: Receive the UE's trusted location information sent by the first network element;

[0120] S2120: Save the trusted location information.

[0121] The second network element can be an access network element, including but not limited to: base stations, etc.

[0122] The first network element may be a core network element, including but not limited to: AMF, etc.

[0123] For example, the second network element can receive verified or obtained through a specific acquisition method trusted location information from the first network element, which can improve service quality when providing location-related services based on the trusted location information of the UE.

[0124] In some embodiments, the trusted location information includes at least one of the following:

[0125] The satellite positioning information that identifies the UE;

[0126] The Tracking Area Identifier (TAI) of the UE is located in;

[0127] The cell identifier that identifies the cell where the UE is located;

[0128] The base station identifier that identifies the base station to which the UE is connected.

[0129] The satellite positioning information may include: location information obtained based on the Global Positioning System, which includes, but is not limited to: latitude and longitude information.

[0130] The TAI that identifies the tracking area where the UE is located can be determined based on the TA to which the UE is currently located.

[0131] like Figure 8 As shown, this disclosure provides an information processing method, executed by a second network element, the method comprising:

[0132] S2210: Receive the UE's trusted location information sent by the first network element;

[0133] S2220: Save the trusted location information;

[0134] S2230: Based on the trusted location information of the UE, perform the mapping of the trusted location information to the cell identifier serving the UE.

[0135] In this embodiment of the disclosure, by mapping the trusted location information to cell information, it is possible to know the cell used by the UE for access.

[0136] If the cell where the UE is located is determined, the paging message can be sent only to the corresponding cell when paging the UE, reducing the number of paging signaling messages that the network needs to send.

[0137] For example, S2230 may specifically include: performing a mapping of the trusted location information to cell information serving the UE based on the trusted location information of the UE.

[0138] It is worth noting that this embodiment can be implemented alone or in combination with the foregoing embodiments.

[0139] like Figure 9 As shown, this disclosure provides an information processing method, executed by a second network element, the method comprising:

[0140] S2310: Receive the UE's trusted location information sent by the first network element;

[0141] S2320: Save the trusted location information;

[0142] S2330: Select an AMF for the UE to access based on the UE's trusted location information.

[0143] It is worth noting that this embodiment can be implemented in combination with the aforementioned embodiment executed by the second network element, or it can be implemented independently.

[0144] In some embodiments of this disclosure, selecting an AMF based on reliable location information can reduce the selection of an AMF due to inaccurate or forged location information, reduce AMF reselection, improve access efficiency, and reduce the phenomenon of UE requests being rejected when accessing an incorrect AMF.

[0145] like Figure 10 As shown, this disclosure provides an information processing method, which is executed by a UE, the method comprising:

[0146] S3110: Receive the UE's trusted location information sent by the first network element;

[0147] S3120: Save the trusted location information.

[0148] The UE can be of various types, such as mobile phones, tablets, wearable devices, in-vehicle devices, smart home devices, or smart office devices.

[0149] The first network element can be a core network element; for example, the core network element is an AMF.

[0150] For example, the UE receives a NAS message containing the trusted location information.

[0151] After receiving the trusted location information, it will be saved locally. Subsequent location-related services can provide trusted services based on the trusted location information and improve service quality.

[0152] In some embodiments, the trusted location information includes at least one of the following:

[0153] The latitude and longitude information that identifies the UE can, for example, be satellite positioning information obtained by satellite positioning.

[0154] The Tracking Area Identifier (TAI) of the UE is located in;

[0155] The cell identifier that identifies the cell where the UE is located;

[0156] The base station identifier that identifies the base station to which the UE is connected.

[0157] The satellite positioning information may include: location information obtained based on the satellite positioning system, which includes, but is not limited to: latitude and longitude information.

[0158] The TAI that identifies the tracking area where the UE is located can be determined based on the TA to which the UE is currently located.

[0159] like Figure 11 As shown, this disclosure provides an information processing method, which is executed by a UE, the method comprising:

[0160] S3210: Receive the UE's trusted location information sent by the first network element;

[0161] S3220: Save the trusted location information.

[0162] S3230: Perform access registration or registration update based on the trusted location information.

[0163] It is worth noting that the information processing method executed by the UE can be executed alone or in combination with the aforementioned information processing method executed by the UE.

[0164] In some embodiments, the UE performs access registration or registration update based on trusted location information, which facilitates better network control over UE access, such as performing compliance verification.

[0165] like Figure 12 As shown, this disclosure provides an information processing method, which is executed by a UE, the method comprising:

[0166] S3310: Receive the UE's trusted location information sent by the first network element;

[0167] S3320: Save the trusted location information.

[0168] S3330: Based on the trusted location information, determine whether to execute FA-based access prohibition and / or SAR-based access control.

[0169] By using trusted location information in conjunction with FA or SAF for access control, the UE can achieve precise control.

[0170] It is worth noting that the information processing method executed by the UE can be executed alone or in combination with the aforementioned information processing method executed by the UE.

[0171] To address the issue of unreliable location information provided by the UE, which may lead to location spoofing, this disclosure proposes a method for providing reliable location information of the UE from the network side. This method resolves issues such as network control failures caused by unreliable UE location. Specific implementation may include:

[0172] The first network element obtains the UE's trusted location information and provides it to the second network element. The first network element is a core network element, such as an AMF (Access Module). The second network element is an access network element, such as a gNB (Gateway NodeB), or the UE.

[0173] The location information obtained by the first network element through the LCS program can be considered as reliable location information;

[0174] Location information verified by the first network element can be considered reliable location information.

[0175] The UE's location information can be any information that identifies the UE's location, such as Global Navigation Satellite System (GNSS) information or Tracking Area Indentity (TAI).

[0176] The location information deemed trustworthy can be proactively provided to the first network element by the second network element. Alternatively, the second network element can provide the location information to the first network element at the request of the first network element.

[0177] When the second network element is an access network element, the second network element performs CellID mapping based on the UE's trusted location information and performs AMF selection.

[0178] When the second network element is a UE, the second network element performs PLMN selection based on the UE's trusted location information, determines registration update, performs SAR and / or FR control, etc.

[0179] This embodiment illustrates that when a UE accesses the fifth-generation core network (5GC) via satellite, during the initial access process, the UE provides its location information A, and the gNB selects PLMN_A for access based on the location information A, thus completing the initial access attachment process.

[0180] Subsequently, AMF_A initiates the LCS procedure to obtain the UE's location information B, and performs location verification based on the location information B. This location information B is one of the aforementioned trusted location information.

[0181] AMF_A detects that the UE is at the location indicated by trusted location information B and prohibits access to PLMN_A. AMF_A initiates the UE's detach procedure and provides the trusted location information B to the gNB, which then performs PLMN selection and re-completes the access procedure.

[0182] like Figure 13 As shown, this disclosure provides an information processing method, which may include: 1. The UE initiates a registration request, carrying UE location information A.

[0183] 2. After receiving the registration request, the gNB performs AMF selection based on the location information A, and selects AMF_A.

[0184] 3. The gNB maps location information A to the corresponding CGI and includes it in an NGAP message, which is then sent to AMF_A. 4. AMF_A completes location verification and allows the UE to access PLMN_A at location A.

[0185] 5. The remaining process of access registration between UE and AMF_A.

[0186] 6. AMF_A initiates the LCS procedure to obtain the UE's location information B; this location information B is the aforementioned trusted location information.
