[0002] In mobile communication technology, for a mobile terminal to obtain services from the network, it must first complete a network registration process. Network registration involves registering the terminal with the core network, allowing the core network to authenticate the mobile terminal and prepare it to provide services. For example, the terminal triggers the network registration process when it is powered on or when airplane mode is turned off, or when it moves from its current Tracking Area (TA) to a new TA. Currently, when a large number of terminals simultaneously initiate the registration process at a certain location, it can easily lead to network signaling overload, resulting in a low success rate for terminal network registration.

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in this application's specification are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0026] In mobile communication technology, for a terminal to obtain services provided by the network, it must first complete the network registration process. Specifically, the terminal triggers a Radio Resource Control (RRC) connection establishment simultaneously with Random Access Channel (RACH) access, and the "registration" process is triggered concurrently with the RRC connection. Registration is with the core network, and its purpose is to allow the core network to authenticate the terminal and prepare it to provide services. This is a necessary step for the terminal to perform other registration actions. Network registration is generally divided into two types:

[0027] 1) Initial registration: When the terminal is powered on or airplane mode is turned off, the terminal will trigger the network initial registration process;

[0028] 2) Mobile update registration: When a terminal moves from the current TA to a new TA, the mobile update registration process is triggered.

[0029] When users arrive at their destination via ports of entry, high-speed rail, or air travel, a large number of terminals from the same country or region simultaneously attempt to register with the roaming network. This massive volume of network requests can instantly overwhelm the core network elements of the roaming operator, such as the Access and Mobility Management Function (AMF). This can easily lead to network signaling overload, resulting in low terminal registration success rates or lengthy registration processes. In unfamiliar overseas environments, the inability of terminals to connect to the network promptly will directly trigger user anxiety, becoming a break in the mobile network experience.

[0030] Therefore, how to effectively improve the network registration success rate of terminals in congested network scenarios, thereby enhancing the user's online experience, is an urgent problem to be solved.

[0031] In unfamiliar overseas environments, the inability of a device to connect to the internet in a timely manner will directly trigger user anxiety and become a break in the mobile network experience.

[0032] The network registration method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0033] See Figure 1 , Figure 1 This is a flowchart of a network registration method provided in an embodiment of this application, such as... Figure 1 As shown, it includes the following steps:

[0034] Step 101: The terminal performs a cell search and obtains at least one first cell to be registered;

[0035] In this embodiment, the terminal can perform a cell search if the cell search conditions are met, in order to obtain at least one first cell to be registered, i.e., a cell that meets the registration conditions. Here, cell search can be understood as network scanning.

[0036] Optionally, the aforementioned first cell can be understood as a cell that supports a first network standard, such as a cell that supports 5G networks.

[0037] Step 102: The terminal determines the first registered cell based on the network registration information sent by the server and the signal quality of the at least one first cell to be registered. The network registration information includes historical registration information of at least one second cell, the historical registration information includes historical registration success rate, and the at least one second cell includes the first registered cell.

[0038] In this embodiment, the second cell can be associated with the location of the terminal. For example, the server can send network registration information based on the terminal's location, wherein the coverage area of ​​the second cell includes the terminal's current location. In some embodiments, the aforementioned at least one second cell can be understood as all cells that the terminal can search for at its current location, or as all cells at a specified frequency that the terminal can search for at its current location. The aforementioned at least one second cell includes the first cell.

[0039] Optionally, the terminal may receive the aforementioned network registration information from the server during the cell search process. For example, the terminal may send a network registration information retrieval request to the server during the cell search process or when it is determined to perform a cell search, and the server will send the network registration information to the terminal based on the request. The network registration information retrieval request may include the terminal's location.

[0040] It should be understood that the aforementioned network registration information may be part of the network registration information stored in the network registration knowledge base of the service.

[0041] Optionally, the historical registration information may also include, but is not limited to, the following: community identifier and average historical registration duration.

[0042] Optionally, each terminal can record context information after each network registration and upload the context information to the server. The context information may include at least one of the following: timestamp, Public Land Mobile Network (PLMN), cell identifier, network registration result, failure reason value, and signal strength. The server constructs a network registration knowledge base by aggregating the data reported by the terminals. For example, it evaluates network registration priority for networks in the same scenario and within the same PLMN according to their time distribution, obtaining the historical registration success rate and historical average registration duration for each cell. This network registration knowledge base includes the cell identifier, registration success rate, and historical average registration duration for each cell.

[0043] Optionally, the server can obtain the historical registration information of the second cell from the network registration knowledge base based on the location of the terminal, and send the historical registration information of the second cell to the terminal.

[0044] Optionally, the terminal can determine the initial registration cell, i.e., the first registration cell, based on the historical registration information and signal quality of the first cell. Since combining the historical registration information and signal quality of the first cell allows for the selection of cells with higher success rates for registration, the registration success rate is improved.

[0045] Step 103: The terminal sends a first registration request to the first registered cell.

[0046] In this embodiment of the application, the aforementioned first registration request can be understood as a request for initial registration attempt. After the terminal determines the first registration cell, it can initiate an initial registration attempt to the first registration cell.

[0047] This embodiment of the application uses a terminal to perform cell search and obtain at least one first cell to be registered. The terminal determines a first registration cell based on network registration information sent by a server and the signal quality of the at least one first cell to be registered. The network registration information includes historical registration information of at least one second cell, and the historical registration information includes historical registration success rates. The at least one second cell includes the first registration cell. The terminal sends a first registration request to the first registration cell. By combining the historical registration information and signal quality of the first cell, cells with higher success rates can be selected for registration, thereby improving the registration success rate.

[0048] Optionally, in some embodiments, the terminal determines the first registered cell based on network registration information and the signal quality of the at least one first cell to be registered, including:

[0049] The terminal determines the historical registration success rate of each of the first cells based on the network registration information;

[0050] The terminal evaluates the first cell based on the historical registration success rate and the signal quality of the first cell to obtain a score value for each first cell. The score value is used to represent the probability that the terminal successfully registers in the first cell.

[0051] The terminal identifies the first cell with the highest score as the first registered cell.

[0052] In this embodiment, historical registration success rate and signal quality can be scored. The higher the historical registration success rate, the higher the corresponding score; the higher the signal quality, the higher the corresponding score. For example, scores of 0 to 10 based on historical registration success rate correspond to historical registration success rates of 0% to 100%, respectively. Scores of 2, 4, and 6 based on signal quality correspond to low, medium, and high signal quality, respectively. Assuming a first cell has a historical registration success rate of 50%, a score of 5 based on historical registration success rate, and a signal quality score of 4 based on signal quality, then the score of the first cell is 5 + 4 = 9. Of course, in some embodiments, further weighting can be configured. For example, the weight of historical registration success rate is 0.8, and the weight of signal quality is 0.2, then the score of the aforementioned first cell is 5 * 0.8 + 4 * 0.2 = 4.8. In this way, a cell with a slightly weaker signal but a high historical registration success rate can be given higher priority than a cell with a very strong signal but a low historical success rate.

[0053] It should be understood that, in some embodiments, a priority cell list can be obtained based on the above-mentioned score value, and the cell with the highest priority is determined as the first registered cell based on the priority cell list.

[0054] It should be noted that in some embodiments, the scoring method for historical registration success rate and signal quality can be set according to the actual situation, including but not limited to the method described in the above embodiments. For example, more levels can be set for signal quality.

[0055] Optionally, in some embodiments, the above-mentioned score value may further take into account the average registration time of the cell. For example, the shorter the average registration time, the higher the corresponding score.

[0056] Optionally, in some embodiments, after the terminal sends a first registration request to the first registered cell, the method further includes:

[0057] The terminal receives a first registration response message sent by the first registered cell, the first registration response message including registration rejection information;

[0058] The terminal sends a second registration request based on the registration rejection information.

[0059] In this embodiment, the first registration cell can determine whether to allow terminal registration based on the first registration request. If terminal registration is allowed, a first registration response message containing registration acceptance information can be sent. If terminal registration is not allowed, a first registration response message containing registration rejection information can be sent.

[0060] Optionally, the registration rejection information may include a rejection reason value. For example, in some embodiments, the registration rejection information may include any of the following:

[0061] The first rejection reason value can be #22 or #15. When the first rejection reason value is #22, it indicates network congestion. When the first rejection reason value is #15, it indicates that no suitable cells were found in the tracking area.

[0062] The second rejection reason value is used to indicate a protocol error or an unspecified condition. The second reason value can be #111.

[0063] Optionally, in some embodiments, when the first rejection reason value can be #22, the registration rejection information may further include a first timer, which is used to indicate the time when the terminal stops registering.

[0064] It should be understood that, in this embodiment of the application, after receiving the registration rejection information, the terminal sends a second registration request based on the registration rejection information. Compared with the prior art, which requires waiting for a period of time before re-registering, this embodiment of the application can shorten the time for the terminal to complete the registration.

[0065] Optionally, in some embodiments, the terminal sends a second registration request based on the registration rejection information, including:

[0066] If the registration rejection information includes a first rejection reason value, the terminal performs a cell search again to obtain at least one third cell, which is another cell to be registered besides the first registered cell;

[0067] The terminal determines N second registered cells based on network registration information and the signal quality of the at least one third cell, where N is a positive integer.

[0068] The terminal sequentially sends the second registration request to each of the N second registration cells.

[0069] In this embodiment, after a terminal's registration in the first registered cell is rejected, and the rejection reason is the first rejection reason value, the terminal can immediately re-search for cells and determine N second registered cells from other unregistered third cells based on network registration information and the signal quality of the third cells. The terminal then sequentially registers with these N second registered cells, thereby improving the success rate of terminal registration. The network registration information includes historical registration information of at least one second cell, which includes the third cell.

[0070] Optionally, the value of N can be set according to actual needs. For example, in some embodiments, N can be 1, 2 or 3.

[0071] It should be noted that, in this embodiment, the method of determining N second registered cells based on network registration information and the signal quality of the third cell can be the same as the method of determining the first registered cell based on network registration information and the signal quality of the first cell. For example, in some embodiments, the method of determining N second registered cells includes:

[0072] The terminal determines the historical registration success rate of each of the third cells based on the network registration information;

[0073] The terminal evaluates the third cell based on the historical registration success rate and the signal quality of the third cell to obtain a score value for each third cell. The score value is used to represent the probability that the terminal successfully registers in the third cell.

[0074] The terminal identifies the top N cells with the highest scores from highest to lowest as the second registered cells.

[0075] Furthermore, when determining the score of the third cell, the registration evaluation time and / or weight configuration can be further considered. The specific method can refer to the relevant content of determining the score of the first cell in the above embodiment, which will not be repeated here.

[0076] Optionally, in some embodiments, the terminal sequentially sends the second registration request to the N second registration cells, including:

[0077] The terminal sends a second registration request to the nth second registration cell;

[0078] If the terminal fails to register in the nth second registration cell, the terminal sends a second registration request to the (n+1)th second registration cell.

[0079] When the terminal successfully registers in the nth second registration cell, the terminal stops sending the second registration request.

[0080] In this embodiment, the terminal sequentially sending the second registration request to the N second registration cells can be understood as the terminal sending the second registration request to each of the N second registration cells in descending order of their score values ​​until registration is successful. It should be noted that the terminal's behavior differs depending on the rejection reason value.

[0081] Optionally, in some embodiments, when the first rejection reason value is used to indicate network congestion, the registration rejection information further includes a first timer, which indicates the time the terminal waits to register; or,

[0082] The first rejection reason value is used to indicate that no suitable cell was found in the tracking area.

[0083] In this embodiment, the aforementioned first timer can be understood as or replaced by a T3346 timer, or by a congestion timer. During the operation of the first timer, the terminal is prohibited from sending registration requests to the network. Because in this embodiment, the terminal ignores the first timer, directly performs cell search, and sends a second registration request, the terminal's registration time can be shortened, allowing the terminal to access the network as quickly as possible.

[0084] It should be understood that, in the embodiments of this application, the terminal performing cell search and the terminal re-performing cell search can be understood as the terminal performing cell search on known frequency points, such as searching for networks on previously camped frequency points and networks on frequency points stored in the user identification card. In related technologies, when the registration rejection information includes #15, the terminal directly initiates a full-band search, which leads to significant power consumption. However, in this application, when the registration rejection information includes #15, a full-band search is not performed, thereby reducing the terminal's power consumption.

[0085] Optionally, in some embodiments, the method further includes:

[0086] If the terminal fails to register in the N second registration cells, the terminal performs the first process;

[0087] The first process includes at least one of the following:

[0088] If the first rejection reason value indicates network congestion, the terminal will re-perform cell search after the first timer expires, determine a third registered cell based on the signal quality of the cell, and send a third registration request to the third registered cell.

[0089] When the first rejection reason value indicates that no suitable cell was found in the tracking area, the terminal initiates a full-band cell search.

[0090] Optionally, if the first rejection reason value indicates network congestion and the first timer times out, the terminal performs a cell search again, determines a third registered cell based on the signal quality of the cell, and sends a third registration request to the third registered cell. This can avoid the terminal from registering frequently and avoid the terminal's power consumption from registration failures.

[0091] Optionally, if the first rejection reason value indicates that no suitable cell was found in the tracking area, the terminal initiates a full-band cell search. By performing a full-band cell search, the success rate of terminal registration can be improved, enabling the terminal to complete registration as soon as possible.

[0092] Optionally, in some embodiments, the terminal sends a second registration request based on the registration rejection information, including:

[0093] If the registration request message includes a second rejection reason value, the terminal sends the second registration request to the first registration cell again; wherein the second rejection reason value is used to indicate a protocol error.

[0094] In this embodiment, the terminal sending a registration request to the first registered cell again can be understood as the terminal sending a simplified registration request, thereby eliminating errors caused by the terminal sending non-standard optional information. If the registration is rejected again, the cell search is performed again. This avoids increased terminal power consumption due to errors caused by the terminal sending non-standard optional information, and at the same time shortens the terminal's network registration time.

[0095] It should be noted that, in the embodiments of this application, if registration fails in N second registered cells, the terminal can execute relevant standard procedures, such as disabling the first type of network for a period of time.

[0096] Optionally, in some embodiments, if the terminal receives the registration rejection information sent by the first registered cell again, the terminal performs a cell search again to obtain at least one third cell, and determines N second registered cells based on the network registration information and the signal quality of the at least one third cell, where N is a positive integer; and sends a second registration request to the N second registered cells in sequence.

[0097] Optionally, the method of sending the second registration request based on at least one third cell is the same as the method of sending the second registration request based on at least one third cell when the registration rejection information includes the first rejection reason value, and will not be described again here.

[0098] Optionally, in some embodiments, the terminal performs a cell search to obtain at least one first cell to be registered, including:

[0099] The terminal obtains the location information of the terminal;

[0100] The terminal determines whether its network registration scenario is an outbound or inbound scenario based on the location information.

[0101] When the terminal is in an outbound or inbound scenario, the terminal performs a cell search to obtain at least one first cell to be registered.

[0102] In this embodiment of the application, since high-density users typically access the network in outbound and inbound scenarios, leading to network congestion, the network registration scenario of the terminal can be determined based on the terminal's location information, thereby reducing the terminal's behavior of obtaining network registration information and thus reducing the overhead of communication signaling between the terminal and the server.

[0103] Of course, in some embodiments, the solution of this application can also be applied to scenarios with high-density user access networks, such as concerts and stadiums, which will not be elaborated here.

[0104] It should be noted that during the network registration process, the terminal can record the context information of each registration step and the context information after each registration, and package this context information. The terminal can report the recorded context information to the server in real time or periodically to update the server's network registration knowledge base.

[0105] To better understand this application, the following explanation will use a specific processing scenario as an example.

[0106] In this embodiment, firstly, an outbound roaming network registration knowledge base can be constructed through interaction between the terminal and the server, defining the registration priority of different network cells; secondly, when a user arrives at their destination, the terminal scans available networks and matches them with the network registration knowledge base sent by the server to obtain the cell with the highest registration success rate for access; when the terminal's first registration is rejected, the registration retry scheme is adjusted differently based on the failure reason value sent by the network.

[0107] This application embodiment constructs an outbound roaming network registration knowledge base based on a terminal and a server, including the following steps:

[0108] (1) Scene recognition: The terminal can effectively identify whether it is currently in an outbound scene and identify specific location information by combining the Global Positioning System (GPS), Wireless Fidelity (WIFI), or base station positioning.

[0109] (2) Data recording: After each network registration attempt, the terminal records key context information, including: timestamp, PLMN, Cell ID, network registration result, failure reason value, signal strength, etc. The terminal packages the above information and uploads it to the server.

[0110] (3) Data analysis and labeling: The server aggregates multiple data reports from the terminal, evaluates the network registration priority of the same PLMN in the same scenario according to the time distribution, and calculates the historical registration success rate and historical average registration time of the cell.

[0111] Reference Figure 2 The preferred access process based on the roaming network registration knowledge base in this embodiment includes the following steps:

[0112] (1) When a user arrives at their destination after leaving the country, if it is by plane landing, the terminal will generally turn on or turn off the flight mode; if it is by port or high-speed rail crossing, the terminal also needs to switch to the roaming destination cell; regardless of the way of leaving the country, the terminal needs to re-initiate the network registration request signaling.

[0113] (2) The terminal obtains all available network cells at the current location by scanning the network and matches them with the network registration knowledge base sent by the cloud; where available network cells can be understood as cells to be registered that meet the registration conditions.

[0114] (3) The terminal obtains a list of preferred cells. Through weight configuration, a cell with a slightly weaker signal but a high historical registration success rate can be given higher priority than a cell with a very strong signal but a low historical registration success rate.

[0115] (4) The terminal prioritizes the cell with a high historical registration success rate and initiates the first registration attempt to reduce the probability of rejection from the source.

[0116] Reference Figure 3 The adaptive retry process based on the roaming network registration knowledge base and rejection reason value in this embodiment includes the following steps:

[0117] (1) If the terminal’s first registration attempt is rejected, the terminal does not directly follow the network standard retry behavior, but instead adopts an adaptive retry mechanism based on the rejection reason value issued by the network.

[0118] (2) If the rejection reason value sent by the network is #22, a T3346 timer will be sent along with it. The standard procedure is that the terminal needs to wait for the T3346 timer to expire before retrying the registration. The solution in this application is: the terminal immediately scans other available cells and compares them with the knowledge base to filter out high-priority candidate cells; the terminal actively initiates registration attempts to N candidate cells. If any one of the attempts is successful, the T3346 timer is stopped immediately and access is completed. If all candidate cell attempts fail, the terminal waits silently until the original T3346 timer expires before executing the standard retry procedure.

[0119] (3) If the rejection reason value issued by the network is #15, the standard procedure is for the terminal to initiate a full-band search. Referring to #22, the solution in this application is: the terminal immediately scans other available cells and compares them with the knowledge base, filters out high-priority candidate cells, and actively initiates registration attempts to N candidate cells according to the "network registration priority". If all candidate cell attempts fail, the standard procedure is executed, such as the terminal initiating a full-band search.

[0120] (4) If the network-issued rejection reason value is #111, the terminal first attempts to send a simplified registration request to rule out errors caused by the terminal sending non-standard optional information. If the second request is still rejected, refer to #22. The terminal immediately scans other available cells and compares them with the knowledge base to filter out high-priority candidate cells. Then, according to the "network registration priority", the terminal actively initiates registration attempts to N candidate cells. If all candidate cell attempts fail, the standard procedure is executed, such as disabling 5G for T hours.

[0121] (5) Knowledge base update: Regardless of whether the above steps are successful or not, the terminal will update the complete information of this registration process as a new record to the local knowledge base, so as to realize the continuous self-learning and optimization of the model.

[0122] The network registration method provided in this application can be executed by a network registration device. This application uses a network registration device executing the network registration method as an example to illustrate the network registration device provided in this application.

[0123] See Figure 4 , Figure 4 This is a structural diagram of the network registration device provided in the embodiments of this application, applied to a terminal, such as... Figure 4 As shown, the network registration device 400 includes:

[0124] Search module 401 is used to perform cell search and obtain at least one first cell to be registered;

[0126] The sending module 403 is used to send a first registration request to the first registered cell.

[0127] Optionally, the processing module 402 is specifically configured to: determine the historical registration success rate of each of the first cells based on the network registration information; evaluate the first cells based on the historical registration success rate and the signal quality of the first cells to obtain a score value for each of the first cells, the score value being used to represent the probability that the terminal successfully registers in the first cell; and determine the first cell with the highest score value as the first registration cell.

[0129] The receiving module is configured to receive a first registration response message sent by the first registered cell, wherein the first registration response message includes registration rejection information;

[0130] The sending module 403 is also used to send a second registration request based on the registration rejection information.

[0131] Optionally, the sending module 403 is specifically configured to: if the registration rejection information includes a first rejection reason value, perform a cell search again to obtain at least one third cell, wherein the at least one third cell is another cell to be registered besides the first registered cell; determine N second registered cells based on the network registration information and the signal quality of the at least one third cell, where N is a positive integer; and send the second registration request to the N second registered cells in sequence.

[0132] Optionally, if the first rejection reason value is used to indicate network congestion, the registration rejection information further includes a first timer, which indicates the time the terminal waits to register; or,
