Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to a network registration method and device, electronic equipment and computer program product. BACKGROUND

[0002] In 3GPP 24.501 and 24.301, for a terminal accessing a 3GPP network via satellite, an error code #78 (PLMNs not allowed to operate at the present UE location) is added in the 5G 5GMM layer and the 4G EMM layer. When receiving a registration or service request initiated by a satellite access terminal, the network side can obtain the location information of the terminal from the NG-RAN (5G) or eNodeB (4G), so as to determine whether the terminal can be provided with services at this location. If the services cannot be provided, a corresponding rejection message is sent to the terminal, and the error code #78 is carried.

[0003] After receiving the error code #78, the terminal stores it in a local "current location PLMN forbidden operation list", such as the PLMN that receives the error code #78.

[0004] In 3GPP 24.501 and 24.301, the terminal is required to remove all entries in the "current location PLMN forbidden operation list" when the USIM is removed. This approach does not take into account the next time the card is inserted. If the USIM inserted this time is the same as the USIM inserted last time, the terminal location does not change much, and the PLMN attempting to access via satellite exists in the list before the USIM is removed. The network will still reply with a rejection message and carry the error code #78, so the terminal makes unnecessary satellite access attempts, causing consumption of air interface resources and network resources.

[0005] At present, there is no effective solution to the problem of unnecessary access attempts to forbidden cells in the case of reinserting the USIM, causing unnecessary consumption of cell resources. SUMMARY

[0006] The embodiments of the present application provide a network registration method, device, electronic equipment and computer program product, to at least solve the technical problem of unnecessary access attempts to forbidden cells in the case of reinserting the USIM, causing unnecessary consumption of cell resources.

[0013] Optionally, the method further comprises: monitoring a storage duration of the target forbidden information stored by the terminal; judging whether the storage duration reaches a preset time threshold; and deleting the target forbidden information in the case that the storage duration reaches the preset time threshold.

[0014] According to another aspect of the embodiments of the present application, a network registration apparatus is further provided, comprising: a detection module, configured to detect whether the terminal has pre-stored target forbidden information corresponding to a target user identification card in the case that the terminal detects that the target user identification card is inserted, wherein the target forbidden information is used at least for recording a target cell which is forbidden to access a public land mobile network; a rejection module, configured to reject the target cell from a plurality of preset cells recorded in an accessible cell list of the terminal to obtain a to-be-registered cell list in the case that the terminal has pre-stored the target forbidden information, wherein the accessible cell list is used for recording a plurality of preset cells detected by the terminal; and a registration module, configured to initiate a registration request for accessing a public land mobile network to a to-be-accessed cell in the to-be-registered cell list.

[0026] NTN (non-terrestrial network): It is a general term for any non-terrestrial flying object network, including satellite communication networks and high-altitude platform systems.

[0027] PLMN (Public Land Mobile Network): A certain type of cellular mobile communication network of a certain operator in a certain country or region is called PLMN.

[0028] According to the embodiments of the present application, a network registration method embodiment is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order.

[0029] Figure 1 is a flowchart of a network registration method according to an embodiment of the present application, as shown in Figure 1 The method comprises the following steps:

[0030] In step S102, in the case that the terminal detects that the target user identification card is inserted, it is detected whether the terminal has pre-stored target forbidden information corresponding to the target user identification card, wherein the target forbidden information is used at least for recording target cells forbidden for the terminal to access the public land mobile network;

[0031] In step S104, in the case that the terminal has pre-stored target forbidden information, the target cell is excluded from a plurality of preset cells recorded in an accessible cell list of the terminal, to obtain a to-be-registered cell list, wherein the accessible cell list is used for recording a plurality of preset cells detected by the terminal.

[0032] In step S106, a registration request for accessing the public land mobile network is initiated to a to-be-accessed cell in the to-be-registered cell list.

[0033] In the embodiment of the present application, in the case that the terminal detects that the target user identification card is inserted, it is detected whether the terminal has pre-stored target forbidden information corresponding to the target user identification card, wherein the target forbidden information is used at least for recording target cells forbidden for the terminal to access the public land mobile network; in the case that the terminal has pre-stored target forbidden information, the target cell is excluded from a plurality of preset cells recorded in an accessible cell list of the terminal, to obtain a to-be-registered cell list, wherein the accessible cell list is used for recording a plurality of preset cells detected by the terminal; a registration request for accessing the public land mobile network is initiated to a to-be-accessed cell in the to-be-registered cell list, so that the terminal can continue to save the target forbidden information corresponding to the target user identification card after the target user identification card is removed, and then can continue to use the target forbidden information saved in the terminal to perform registration after the target user identification card is inserted again, and further based on the target forbidden information saved in the terminal, the terminal can avoid access attempts to the target cells indicated by the target forbidden information, thereby achieving the technical effect of avoiding unnecessary resource consumption of the target cells, and further solving the technical problem of unnecessary access attempts to the cells forbidden for access in the case that the USIM is reinserted, resulting in unnecessary consumption of cell resources.

[0034] In the above step S102, the target user identification card USIM is a chip card used for storing user identity information and other personal information, and is used together with a mobile phone or other mobile devices.

[0035] In the above step S102, the public land mobile network PLMN is a network infrastructure used for providing mobile communication services, including a group of base stations, a core network and other related devices, and provides communication services for users through wireless signal coverage in a certain area.

[0036] Optionally, the base station can use a communication satellite.

[0037] Optionally, the terminal can access a public land mobile network (PLMN) through the base station.

[0038] Optionally, the target cell, the preset cell and the cell to be accessed are all communication cells using a communication satellite as a base station.

[0039] In the step S102, the target barring information can be a "current location PLMN barring operation list" stored locally in the terminal, which can include: a PLMN receiving an error code #78; a current geographical location of the terminal (if the terminal can obtain it); and a distance value specified by the terminal (if the current geographical location of the terminal can be obtained).

[0040] It should be noted that the terminal can initiate a registration or service request to the base station (or the communication satellite), and then the base station (or the communication satellite) determines whether the terminal in this location can be provided with services. If the terminal cannot be provided with services, the base station (or the communication satellite) sends a corresponding rejection message to the terminal, carrying an error code #78.

[0041] Optionally, the cell corresponding to the public land mobile network (PLMN) recorded in the "current location PLMN barring operation list" is the target cell.

[0042] Optionally, the terminal is not allowed to access the public land mobile network (PLMN) through the target cell when a specific access condition is not met, wherein the specific access condition is that the distance between the location of the terminal and the location receiving the error code #78 is less than the distance value in the list, or the terminal needs to access for emergency services, that is, the terminal can access the target cell when the distance between the location of the terminal and the location receiving the error code #78 is less than the distance value in the list, or when the terminal needs to access for emergency services.

[0043] Optionally, the target barring information can be deleted, that is, the "current location PLMN barring operation list" can be deleted, when the terminal meets a deletion condition, wherein the deletion condition includes: the terminal successfully accesses the public land mobile network (PLMN) through the communication satellite for non-emergency services, and a timer timeout (that is, the storage time of the target barring information stored by the terminal reaches a preset time threshold).

[0044] In the step S102, the target barring information pre-stored by the terminal can be obtained by the terminal when the terminal detects the insertion of a target user identification card for the last time.

[0045] Optionally, the terminal initiates registration or sends a service request to the base station (or communication satellite) in the case that the terminal detects the target user identification card is inserted, and then generates the target forbidden information according to a rejection message returned by the base station (or communication satellite) in the case that the terminal receives the rejection message (such as receiving error code #78 of the PLMN).

[0046] In the step S104, the preset cell is a communication cell covering the wireless signal of the terminal.

[0047] Optionally, the terminal can search a plurality of preset cells covering the wireless signal of the terminal to obtain an accessible cell list in the case that the terminal detects the target user identification card is inserted.

[0048] In the step S104, the plurality of preset cells in the accessible cell list includes the target cell, and the terminal can delete the target cell from the accessible cell list to obtain a to-be-registered cell list including a plurality of to-be-accessed cells before the registration process of accessing the public land mobile network, and then the terminal can initiate a registration request of accessing the public land mobile network to the to-be-accessed cells in the to-be-registered cell list, thereby avoiding unnecessary registration request to the target cell and avoiding unnecessary resource consumption of the target cell.

[0049] As an optional embodiment, in the case that the terminal detects the target user identification card is inserted, the step of detecting whether the terminal has the pre-stored target forbidden information corresponding to the user identification card includes: detecting whether the terminal has pre-stored preset forbidden information in the case that the terminal detects the target user identification card is inserted; identifying a preset user identifier corresponding to the preset forbidden information in the case that the terminal has the pre-stored preset forbidden information, wherein the preset user identifier is a unique identifier of a preset user identification card corresponding to the preset forbidden information; detecting whether the target user identifier of the target user identification card is consistent with the preset user identifier; and determining that the terminal has the pre-stored target forbidden information in the case that the target user identifier is consistent with the preset user identifier.

[0050] In the above embodiments of the present application, in the case that the terminal detects the USIM is inserted, the terminal can first detect whether the terminal has the pre-stored preset forbidden information, and then further compare the user identifier of the inserted USIM with the pre-stored preset forbidden information in the terminal in the case that the terminal has the preset forbidden information, thereby accurately judging whether the terminal has the pre-stored target forbidden information.

[0051] It should be noted that in the case that the target user identifier is consistent with the preset user identifier, the target forbidden information is the preset forbidden information corresponding to the preset user identifier consistent with the target user identifier.

[0052] As an optional embodiment, the method further comprises: in the case that the terminal does not have the preset barring information stored in advance, determining that the terminal does not have the target barring information stored in advance; and in the case that the terminal does not have the target barring information stored in advance, initiating a registration request for accessing the public land mobile network to each preset cell recorded in the accessible cell list.

[0053] The above embodiments of the present application, in the case that the terminal does not have the preset barring information stored in advance, indicate that the terminal does not store any preset barring information, and therefore the terminal does not have the target barring information stored in advance, so that the fast determination of whether the terminal has the target barring information stored in advance can be realized, the determination efficiency is improved, and then in the case that the terminal does not have the target barring information stored in advance, the registration request for accessing the public land mobile network is initiated to each preset cell recorded in the accessible cell list, and the registration of the terminal is completed.

[0054] As an optional embodiment, the method further comprises: in the case that the target user identifier is inconsistent with the preset user identifier, deleting the preset barring information, and initiating the registration request for accessing the public land mobile network to each preset cell recorded in the accessible cell list.

[0055] The above embodiments of the present application, in the case that the preset user identifier of the preset barring information stored in advance by the terminal is inconsistent with the target user identifier of the target user identification card detected by the terminal, indicate that the preset barring information stored by the terminal does not match the target user identification card, and the target user identification card cannot use the preset barring information, and then the preset barring information can be deleted from the terminal, and then the registration request for accessing the public land mobile network is initiated to each preset cell recorded in the accessible cell list, the registration of the terminal is completed, and the target barring information corresponding to the target user identification card is regenerated according to the registration result.

[0056] As an optional embodiment, the method further comprises: in the case that the terminal detects the insertion of the target user identification card, acquiring the accessible cell list according to a preset cell search process, wherein the preset cell search process is used to instruct the terminal to search for a plurality of preset cells.

[0057] The above embodiments of the present application, in the case that the terminal detects the insertion of the target user identification card, the terminal can search for wireless signals according to the preset cell search process, acquire a plurality of preset cells whose signal parameters such as signal strength meet the access requirements of the terminal, and form an accessible cell list, so that the acquisition of the accessible cell list is realized.

[0058] As an optional example, the preset cell search procedure can include: the terminal sends a cell search request to the base station, and the base station sends cell broadcast information to the terminal after receiving the request; the terminal parses the cell identifier and other related information in the received cell broadcast information; the terminal determines the current cell according to the received cell broadcast information and establishes a connection with the cell; after the terminal establishes a connection with the cell, the terminal measures and tracks the signal strength, quality and other parameters of the cell to ensure good communication quality; the terminal can help the cell to optimize and adjust by periodically sending a cell measurement report to improve network performance and coverage.

[0059] Optionally, the plurality of preset cells in the accessible cell list meet the terminal access requirements in terms of signal parameters such as signal strength, and therefore, the preset cells in the accessible cell list can include the target cell, and therefore, before the terminal performs registration, the preset cells in the accessible cell list need to be screened to remove the target cell in the accessible cell list to obtain a to-be-registered cell list including a plurality of to-be-accessed cells, and then the to-be-accessed cells in the to-be-registered cell list are registered.

[0060] As an optional embodiment, the method further includes: in the case that the terminal detects that the target user identification card is removed, detecting whether the terminal has pre-stored target prohibited information; in the case that the terminal has pre-stored target prohibited information, continuing to save the target prohibited information after the terminal removes the target user identification card, wherein the target prohibited information stored by the terminal is used in the case that the terminal detects that the target user identification card is inserted again after the target user identification card is removed.

[0061] The above embodiments of the present application can continue to save the target prohibited information corresponding to the target user identification card after the target user identification card is removed from the terminal, and the target prohibited information can be directly used in the case that the terminal detects that the target user identification card is inserted again, without the need to generate the target prohibited information again, thereby avoiding unnecessary access attempts of the terminal to the target cell indicated by the target prohibited information.

[0062] As an optional embodiment, the method further includes: monitoring the storage duration of the target prohibited information stored by the terminal; determining whether the storage duration reaches a preset time threshold; and deleting the target prohibited information in the case that the storage duration reaches the preset time threshold.

[0063] The above embodiments of the present application can store the target prohibited information corresponding to the target user identification card after the target prohibited information is generated, and start a timer to record the storage duration of the target prohibited information, and then delete the target prohibited information in the case that the timer expires, i.e., the storage duration reaches the preset time threshold, indicating that the target prohibited information has exceeded the use-by date, thereby ensuring the timeliness of the target prohibited information.

[0064] It should be noted that after the timer is started, even if the terminal detects that the target user identity card is removed, the terminal still stores the target prohibition information corresponding to the target user identity card, and the timer continues to run until the timer expires, or the terminal detects that a new user identity card different from the target user identity card is inserted, and then the target prohibition information is deleted.

[0065] It should be noted that the target prohibition information is generated according to a rejection message returned by the target cell, wherein the rejection message indicates that the timer sets a preset time threshold through a “Lower bound timer value IE”, and if the “Lower bound timer value IE” does not exist in the rejection message, the terminal indicates that the timer sets the preset time threshold.

[0066] The application also provides an optional embodiment, which provides a plug-and-play optimization of the current location PLMN forbidden operation list for an NTN terminal. The “current location PLMN forbidden operation list” is not deleted when the USIM is removed, and it is judged whether the same USIM is inserted next time, and the processing of the “current location PLMN forbidden operation list” is determined according to the judgment result.

[0067] Figure 2 It is a plug-and-play optimization scheme of the current location PLMN forbidden operation list for an NTN terminal according to an embodiment of the application, as shown in Figure 2 includes the following steps:

[0068] Step S201, the terminal removes the USIM.

[0069] Step S202, it is judged whether the terminal exists “current location PLMN forbidden operation list”, if exists, continue to optimize the scheme, otherwise end the optimization process.

[0070] Step S203, the “current location PLMN forbidden operation list” is not deleted.

[0071] Step S204, the list related timer continues to run. If the timer expires in the whole optimization process, the corresponding entry in the list is deleted.

[0072] Step S205, the terminal inserts the USIM.

[0073] Step S206, it is judged whether it is the same as the last USIM, and the judgment basis can be the IMSI of the USIM or other unique identifier. If it is the same as the last USIM, step S207 and step S2078 are skipped.

[0074] Step S207: If the inserted USIM is different from the previous USIM, delete the "Current Location PLMN Prohibited Operation List".

[0075] In step S208, the terminal executes the network search and registration process according to the established logic, and the optimization process ends.

[0076] In step S209, the inserted USIM is the same as the previous one, and the terminal executes the predetermined network search process to obtain the list of currently available PLMNs and cells.

[0077] Step S210: Combining the "current location PLMN prohibited operation list" and based on the current location information, determine which PLMNs cannot be accessed in step S209. After excluding the cells that cannot be accessed by PLMNs, execute the registration process in the remaining cells according to the terminal's predetermined logic.

[0078] In the above embodiments of this application, for terminals accessing the 3GPP network via satellite, if a "current location PLMN prohibited operation list" exists, the list should not be deleted immediately when removing the USIM. Instead, when inserting the USIM again, the previous list information and location information should be combined to make a more accurate network registration selection. This avoids the waste of invalid air interface resources and network resources, and shortens the time for the terminal to register with the network.

[0079] According to an embodiment of the present invention, a network registration device embodiment is also provided. It should be noted that the network registration device can be used to execute the network registration method in the embodiments of the present invention, and the network registration method in the embodiments of the present invention can be executed in the network registration device.
