Description

Technical Field

[0001] The present application relates to the field of communication network technology, and in particular to a method and device for maintaining stable communication in a commuting environment. Background Art

[0002] When people commute from their starting point to their destination using public transportation like subways, buses, and light rail, or company or organization-provided shuttles, following pre-set navigation routes during weekdays or specific time periods, such as morning and evening rush hours, mobile network signals significantly impact cellular communications. In particular, during rush hour, heavy traffic can lead to network resources being insufficient to meet user needs, resulting in frequent network lag.

[0003] In existing technologies, to balance load, users with poor signal strength on the edge of the network are kicked off the network during network congestion and redirected to the 2G / 3G network. However, as 2G / 3G networks are phased out, 2G / 3G network lags become more severe, resulting in a poor user experience for 2G / 3G users.

[0004] With respect to the above-mentioned related technologies, the inventors have found that the existing network load balancing method for fixed commuting routes has problems such as network freezes due to redirection to 2G / 3G networks, unstable communications, and poor user experience. Summary of the Invention

[0005] In order to improve the network lag phenomenon of users on fixed commuting routes and improve communication stability, the present application provides a method and device for maintaining communication stability in a commuting environment.

[0007] This application is achieved through the following technical solutions:

[0008] A method for maintaining stable communication in a commuting environment comprises the following steps:

[0009] Determine whether the target user is in a fixed commuting scenario;

[0012] If there is an available 4G / 5G network neighboring area within the location area of ​​the target user and the target user experiences network lag, search for the 4G / 5G network neighboring area and perform TAU registration.

[0013] In a preferred example, the present application can be further configured as follows:

[0014] Record the cell information of the 4G / 5G network used by the target user before being redirected to the 2G / 3G network;

[0016] If there is no available 4G / 5G network neighboring area within the target user's location area and the target user experiences network lag, search for the corresponding 4G / 5G network based on the cell information of the 4G / 5G network used by the target user before being redirected to the 2G / 3G network and attempt to register;

[0017] If the registration is successful, the target user is redirected to the corresponding 4G / 5G network.

[0018] In a preferred example, the present application may be further configured as follows: after the step of redirecting the target user to the corresponding 4G / 5G network, the step further includes:

[0019] The cell information of the redirected 4G / 5G network is marked as an available 4G / 5G network neighboring cell within the location area of ​​the target user, and location area update and network status synchronization are initiated.

[0022] Mark the name, location and time of the redirected 2G / 3G network;

[0023] When the target user is in the marked location and the marked time period again, the target user is prohibited from being redirected to the marked 2G / 3G network name.

[0024] In a preferred example, the present application can be further configured as follows: the step of determining whether the target user is in a fixed commuting scenario includes:

[0025] Counting the number of times the target user continuously switches networks of different cells within a preset time period;

[0026] If the number of times the target user continuously switches networks of different cells within a preset time period reaches a preset number threshold, it is determined that the target user is in a fixed commuting scenario.

[0027] In a preferred example, the present application may be further configured as follows: the step of determining whether the target user is in a fixed commuting scenario further includes:

[0028] Detecting whether the speed of the terminal device of the target user is greater than a preset speed threshold for a continuous preset time;

[0033] In a preferred example, the present application may be further configured as follows: the step of determining whether the target user has a network lag condition further includes:

[0034] Monitoring the terminal device speed and TCP latency of the target user;

[0035] When the terminal device speed of the target user is less than the preset whole-machine rate threshold and the TCP delay is greater than the preset duration, it is determined that the target user does not have a network lag situation.

[0050] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0053] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0054] Reference Figure 1 , an embodiment of the present application provides a method for maintaining stable communication in a commuting environment, and the main steps of the method are described as follows.

[0055] S1: Determine whether the target user is in a fixed commuting scenario;

[0056] S2: If the target user is in a fixed commuting scenario, determining whether the target user is in a call phase;

[0057] S3: If the target user is not in a call phase, determine whether there is an available 4G / 5G network neighboring area within the target user's location area, and determine whether the target user has a network lag;

[0058] S41: If there is an available 4G / 5G network neighboring area within the location area of ​​the target user, and the target user has network lag, search for the 4G / 5G network neighboring area and perform TAU registration.

[0059] Specifically, a fixed commuting scenario refers to a scenario in which commuters commute from a designated departure point to a designated destination along a planned fixed commuting route on weekdays or during a specific time period on weekdays.

[0060] Determine whether the target user is in a fixed commuting scenario based on their mobile terminal. Mobile terminals can be phones, tablets, computers, and more. The mobile terminal determines whether commuters are in a fixed commuting scenario based on user ticket inspection information, sensor information, movement speed information, and network information.

[0061] When the departure place and destination in the user's ticket verification information are consistent with the designated departure place and designated destination respectively, or the location information provided by the sensor is consistent with the designated departure place and designated destination, or the moving speed meets the preset speed threshold, or the network information generates 4G to 4G, 5G to 5G, 4G to 5G, 5G to 4G, 5G to 3G, 5G to 2G, etc., then the target user is determined to be in a fixed commuting scenario.

[0062] In one embodiment, the step of determining whether the target user is in a fixed commuting scenario includes:

[0063] Counting the number of times the target user continuously switches networks of different cells within a preset time period;

[0064] If the number of times the target user continuously switches networks of different cells within a preset time period reaches a preset number threshold, it is determined that the target user is in a fixed commuting scenario.

[0065] For example, if a target user's mobile terminal switches networks continuously, switching between five cells within five minutes (e.g., Cell 1 -> Cell 2 -> Cell 3 -> Cell 4 -> Cell 5), with each cell switching from Cell 1 to Cell 5 being different, this means the target user has changed a preset number of base station sites within a preset timeframe. If the target user's number of consecutive network switches between different cells within a preset timeframe reaches a preset threshold, the target user is considered to be in a fixed commuting scenario. In actual algorithms, the thresholds can be adjusted appropriately based on different scenarios to achieve optimal results.

[0066] In one embodiment, the step of determining whether the target user is in a fixed commuting scenario further includes:

[0067] Detecting whether the speed of the terminal device of the target user is greater than a preset speed threshold for a continuous preset time;

[0068] If the terminal speed of the target user is greater than the speed threshold within a continuous preset time, it is determined that the target user is in a fixed commuting scenario.

[0069] For example, if the target user's mobile terminal speed is greater than 30 km / h for 30 consecutive seconds, the target user is determined to be in a fixed commuting scenario. In actual algorithms, the thresholds of each algorithm can be appropriately adjusted according to different scenarios to achieve the best results.

[0070] Statistics show that mobile networks along fixed commuter routes have the following characteristics:

[0071] (1) Regularity of network base station sequence: The line network has regularity, and the base stations and cells that users pass through each time are relatively fixed;

[0072] (2) Temporal regularity: The network characteristics of commuter routes are characterized by temporal regularity, with frequent network congestion during morning and evening peak hours.

[0073] (3) Strong mobility: The mobile network on commuter routes needs to support the high-speed movement of mobile devices. Bus and subway commuters need to maintain network connection while on the move; there are many network switching operations, either within the same network standard (4G to 4G, 5G to 5G) or across network standards (4G to 5G, 5G to 4G).

[0074] Therefore, it is possible to determine whether the mobile terminal is in a high-speed fixed commuting scenario by positioning and monitoring changes in network residence patterns.

[0075] If the target user is in a fixed commuting scenario, it is determined whether the target user is in a call phase, such as collecting electromagnetic waves or audio signals to determine whether the target user is in a call, so as to determine whether the target user is using a mobile terminal to make a call.

[0076] When the target user is in the call phase, the subsequent optimization algorithm will not be executed.

[0077] If the target user is not in a call phase, it is further determined whether there is an available 4G / 5G network neighboring area within the target user's location area, and whether the target user has a network lag.

[0078] The target user's location area can be set to a 3-kilometer circular area centered on the target user's current location. 4G / 5G network neighboring cells refer to base stations or cells adjacent to the target cell. These help the network determine when and which cell to switch to when the user moves, maintaining uninterrupted connections, optimizing network resource allocation, and achieving network load balancing.

[0079] The 4G network neighbor cell list includes the neighbor cell's physical cell identifier (PCI), frequency information, and type, such as same-frequency, different-frequency, or different-system. The 5G network neighbor cell list includes the neighbor cell's physical cell identifier (PCI), frequency information (including more frequency bands than 4G network neighbor cells, such as millimeter wave bands), and type (including more cell type information than 4G network neighbor cells).

[0080] By measuring the signal strength (RSRP) and signal quality (RSRQ) of the 4G network neighboring cells and comparing them with the corresponding preset thresholds, it is determined whether there is an available 4G network neighboring cell within the target user's location area.

[0081] By measuring the signal strength and quality (SS-RSRP, SS-RSRQ, SINR) of the 5G network neighboring cells, as well as different frequency band and beam information, and comparing them with the corresponding preset thresholds, it is determined whether there is an available 5G network neighboring cell within the target user's location area.

[0082] In one embodiment, the normal operation of the front-end business functions can be ensured by searching for available 4G / 5G network neighboring areas in the background.

[0083] Next, determine whether the target user has network lag, including:

[0084] Detecting an LTE reference signal reception quality value and a signal-to-noise ratio (SNR) of the target user;

[0085] If the LTE reference signal reception quality value is greater than or equal to the signal transmission path threshold in the cellular network, and the LTE reference signal reception quality value is greater than or equal to the phase modulation data transmission threshold, and the signal-to-noise ratio is greater than or equal to the signal-to-noise ratio threshold, it is determined that the target user does not have network lag.

[0086] By detecting the target user's LTE (Long-Term Evolution, mobile communication wireless technology standard) reference signal reception quality value (used to rank the network quality of different LTE candidate cells) and signal-to-noise ratio, the LTE reference signal reception quality value is compared with the preset Pth (Path, signal transmission path in the cellular network) threshold, Qth (Quadrature PhaseShift Keying, phase modulation data transmission) threshold, and the signal-to-noise ratio and SNRth (Signal-to-Noise Ratio Threshold, signal-to-noise ratio) threshold.

[0087] When the LTE reference signal reception quality value is greater than or equal to the Pth threshold, the LTE reference signal reception quality value is greater than or equal to the Qth threshold, and the signal-to-noise ratio is greater than or equal to the SNRth threshold, it is determined that the target user does not have network lag and the target user's network signal is not bad; otherwise, the target user has network lag.

[0088] In this embodiment, the Pth threshold is set to -110 dBm, the Qth threshold is set to 15 dB, and the SNRth threshold is set to 0 dB. In actual application, appropriate adjustments can be made according to the algorithm.

[0089] In one embodiment, the step of determining whether the target user has a network lag condition further includes:

[0090] Monitoring the terminal device speed and TCP latency of the target user;

[0091] When the terminal device speed of the target user is less than the preset whole-machine rate threshold and the TCP delay is greater than the preset duration, it is determined that the target user does not have a network lag situation.

[0092] For example, if the target user's terminal device speed (mobile device speed) is greater than or equal to 100KB / s and the TCP delay is less than or equal to 600ms, the target user is determined to be experiencing network lag, meaning that the Internet service is lag; otherwise, the target user is determined to be not experiencing network lag. The mobile device speed and TCP delay can be appropriately adjusted based on the algorithm.

[0093] Finally, if there is an available 4G / 5G network neighboring area within the target user's location area and the target user experiences network lag, the 4G / 5G network neighboring area is searched, the radio frequency is switched to the 4G / 5G preset and mobile terminal supported frequency, and TAU registration is performed. When the target user experiences network lag in a high-speed environment, if there is an available 4G / 5G network nearby, the SA / LTE network is intelligently selected to redirect or switch the user to the 4G / 5G network again, thereby achieving smooth communication services and reducing the network priority redirected to 2G / 3G to avoid users losing 2G / 3G and affecting the user experience.

[0094] If there is no available 4G / 5G network neighboring area within the target user's location area, and the target user experiences network lag (i.e., poor network coverage), in the prior art, the mobile terminal receives an instruction to redirect the network to 2G / 3G and redirects the target user to the 2G / 3G network. When detecting whether the target user is redirected to the 2G / 3G network, the mobile terminal's network information can be used. If the network information generates information that the 4G / 5G network is switched to the 2G / 3G network, it is determined that the target user with poor edge signal is kicked out of the current network due to network congestion and redirected to the 2G / 3G network. At this time, the target user's network experience is very poor.

[0095] Reference Figure 1 ,In one embodiment, a method for maintaining stable communication in a commuting environment further includes the following steps: S5: recording the cell information of the 4G / 5G network used by the target user before being redirected to the 2G / 3G network;

[0096] S42: If there is no available 4G / 5G network neighboring area within the target user's location area, and the target user experiences network lag, search for the corresponding 4G / 5G network based on the cell information of the 4G / 5G network used by the target user before being redirected to the 2G / 3G network and attempt to register;

[0097] S43: If the registration is successful, the target user is redirected to the corresponding 4G / 5G network.

[0098] When there is no available 4G / 5G network neighboring area within the target user's location area, the system attempts to switch to the original 4G / 5G network, searches for the original 4G / 5G network in the background and performs TAU registration, and redirects the user to the kicked-out 4G / 5G network again to achieve smooth communication services. There is no need to search for available 4G / 5G network neighboring areas within the target user's location area, and the connection efficiency is higher.

[0099] In one embodiment, after the step of redirecting the target user to the corresponding 4G / 5G network, the method further includes:

[0100] The cell information of the redirected 4G / 5G network is marked as an available 4G / 5G network neighboring cell within the location area of ​​the target user, and location area update and network status synchronization are initiated.

[0101] If the mobile terminal successfully switches back to the 4G / 5G network, the location / base station cell is marked as having an available 4G / 5G network neighboring area, a database is established on the server, and the cell information of the marked redirected 4G / 5G network is updated to the list of available 4G / 5G network neighboring areas within the target user's location area, so as to synchronize the location area update with the network status, and speed up the subsequent search for whether there are available 4G / 5G network neighboring areas within the target user's location area.

[0102] Of course, you can also use other mobile phones to report the available 4G / 5G information of the target location / base station cell to enrich the 4G / 5G network neighbor list data pre-stored in the database to speed up the restoration of the target user's 4G / 5G network Internet access function.

[0103] In one embodiment, the following steps are also included:

[0104] Record the name, location, and time when the target user is redirected to the 2G / 3G network;

[0105] Mark the name, location and time of the redirected 2G / 3G network;

[0106] When the target user is in the marked location and the marked time period again, the target user is prohibited from being redirected to the marked 2G / 3G network name.

[0107] By recording the name, location, and time when the target user is redirected to the 2G / 3G network, learning the characteristics of fixed commuting routes, marking the network names, locations, and times where 2G / 3G is likely to be dropped, and based on the spatiotemporal regularity of fixed commuting routes, avoiding 4G / 5G cells that are prone to 2G / 3G drops, lowering the network priority of the target user to be redirected to 2G / 3G, and preventing the target user from being redirected to the 2G / 3G network again, or being unable to return to the 4G / 5G network for a long time after being redirected to the 2G / 3G network.

[0108] Due to the old operator network, outdated configuration, the existence of available 4G / 5G but abnormal configuration, etc., there is a phenomenon of abnormal redirection of 2G / 3G network. In one embodiment, a method for maintaining stable communication in a commuting environment further includes the following steps:

[0109] When receiving a network redirection instruction to 2G / 3G, detect whether an abnormal redirection instruction is received to determine whether there is an abnormal redirection of the 2G / 3G network;

[0110] If an abnormal redirection instruction is received, it is determined that an abnormal redirection to the 2G / 3G network occurs. In this case, the received network redirection to 2G / 3G instruction is ignored and the 2G / 3G frequency is not switched.

[0111] Among them, the abnormal redirection instruction includes the RRC Release instruction. The gNB sends an "RRC ConnectionRelease" message to the UE, which contains the release reason, such as an available 4G / 5G network but abnormal configuration.

[0112] After receiving the network's redirection RRC Release command, ignore the received network redirection to 2G / 3G command, do not interrupt the current 4G / 5G communication service, and initiate location update and network status synchronization in the resident 4G / 5G cell to maintain the current 4G / 5G service.

[0113] To summarize, a method for maintaining stable communication in a commuting environment determines whether the target user is in a fixed commuting scenario to confirm whether it is necessary to intervene in the load balancing method of the mobile network; if the target user is in a fixed commuting scenario, it determines whether the target user is in a call phase to determine whether the network environment of the target user can be optimized at this time; if the target user is not in a call phase, it determines whether there is an available 4G / 5G network neighboring area within the target user's location area, and determines whether the target user has network lag. If there is an available 4G / 5G network neighboring area within the target user's location area and the target user has network lag, the 4G / 5G network neighboring area is searched and TAU registration is performed to redirect the target user to the 4G / 5G network first, avoiding the 2G / 3G network, improving the network lag phenomenon of the user on the fixed commuting route, ensuring smoother communication for the target user in a high-speed mobile commuting scenario, improving user experience, and also improving communication stability.

[0114] In a high-speed mobile network environment, unreasonable switching of 5G SA / 4G LTE networks to 2G / 3G may cause network communication service jams. A method for maintaining stable communication in a commuting environment can accurately identify specific anomalies in specific congested networks, covering anomalies such as poor signal in high-speed communication environments, poor 4G / 5G network signals, and abnormal redirection of 2G / 3G. This can identify in advance possible abnormalities in mobile terminal communication services caused by abnormalities, such as abnormal network configuration causing 2G / 3G dropout, and thus intelligently and effectively prevent users from dropping 2G / 3G, giving priority to 5G SA or 4G LTE networks. This avoids communication service delays or interruptions caused by unreasonable mobile network layout, which affects the communication experience, and improves the stability of mobile terminal communication services and user experience.
