Description

Technical Field

[0001] The present disclosure relates to the field of communications, and in particular, to an information processing method, apparatus, terminal device, and storage medium. Background Art

[0002] Currently, there are multiple radio access technologies (RATs), and most terminal devices also support accessing different networks through different radio access technologies. Among them, from the traditional GSM radio access technology to GERAN, UMTS, LTE, and the current NR, in the mobility management between RATs, a mechanism of setting RAT priority levels is generally adopted to allow the terminal to sequentially attempt to access different RATs.

[0003] The RAT priority levels currently adopted by terminal devices are usually set according to the network operator. This setting method takes effect for all service scenarios of the operator. However, in the actual network situation, there are often different RAT support capabilities for different service scenarios. Since this method has the same RAT selection strategy for all service scenarios of the same operator, it will result in too long RAT access time and poor flexibility in access selection for some service scenarios.

[0085] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0086] In the specification, unless otherwise clearly stated, the terms "first" and "second" are only used for description to distinguish constituent elements and should not be construed as indicating an order. Unless otherwise clearly stated, terms such as "connected" and "fixed" should be understood in a broad sense, including but not limited to "connected" and "fixed" directly, indirectly, detachably, etc.

[0087] Figure 1 It is the flow of an information processing method shown according to an exemplary embodiment Figure 1 , as Figure 1 shown, the method mainly includes the following steps:

[0088] In step 101, when the usage scenario of the terminal device changes, obtain the scenario information of the terminal device.

[0089] In this embodiment, the terminal device can be a handheld device (such as a mobile phone, a laptop computer, a tablet computer, etc.), a vehicle-mounted device, a wearable device, a computing device, etc., which are wirelessly communicated through a network device. The network device can be a base station, a transmission and reception point (TRP), etc., which provide wireless communication functions for the terminal device.

[0090] During the process of a user using a terminal device, the usage scenarios of the terminal device often change dynamically. The usage scenarios can include: the geographical location where the terminal device is located, the type of service executed by the terminal device, the usage mode in which the terminal device is located, etc. Different usage scenarios have different requirements for the radio access technology (RAT). Therefore, when the usage scenario of the terminal device changes, the scenario information of the terminal device can be obtained, and subsequently, based on the scenario information, the matching RAT priority information can be selected for mobility management, which can greatly improve the user experience.

[0091] In step 102, determine the RAT priority management library corresponding to the scenario information.

[0092] In this embodiment, since different types of usage scenarios correspond to different types of scenario information, the terminal device will pre-configure and store different types of RAT priority management libraries. For example: when the scenario information is the geographical location where the terminal device is located, the corresponding RAT priority management library is the RAT priority management library based on the geographical location; when the scenario information is the type of service executed by the terminal device, the corresponding RAT priority management library is the RAT priority management library based on the service; when the scenario information is the usage mode in which the terminal device is located, the corresponding RAT priority management library is the RAT priority management library based on the usage mode.

[0093] That is to say, the types of the RAT priority management libraries correspond one-to-one with the types of the scenario information. There are several types of scenario information, and there are several types of RAT priority management libraries. Each RAT priority management library stores multiple priority information.

[0094] In step 103, select the RAT priority information indicated by the scenario information from the RAT priority management library.

[0095] In this embodiment, after selecting the corresponding RAT priority management library based on the scenario information, select the RAT priority information indicated by the scenario information from the corresponding RAT priority management library. For example: if the type of service of the terminal device changes, obtain the service information currently being carried out by the terminal device, that is, the scenario information. Taking the scenario information as a voice service as an example, determine the RAT priority management library based on the service from multiple RAT priority management libraries based on the scenario information, and select the RAT priority information corresponding to the voice service from the RAT priority management library based on the service.

[0096] In step 104, perform mobility management based on the RAT priority information.

[0097] In this embodiment, due to the mobility of the user, the terminal device needs to change its usage location accordingly, and this mobility characteristic brings about the mobility management of the network. Mobility management is the management of the location information, security, and service continuity of the mobile terminal, and it endeavors to optimize the connection state between the terminal and the network, thereby providing assurance for the application of various network services.

[0098] When performing mobility management based on the RAT priority information corresponding to the scenario information, the RAT with the highest priority in the RAT priority information can be selected for network access. When an abnormality occurs in the access of the RAT with the highest priority, the next-priority RAT can be sequentially selected for handover in the order of priority.

[0099] In this disclosure, mobility management includes at least one of the following: handover between radio access technologies, cell selection, cell reselection, and re-establishment after radio link failure.

[0100] In some embodiments, the usage scenario includes at least one of the following: the country where the terminal device is located; the services performed by the terminal device; the usage mode of the terminal device.

[0101] In this embodiment, since the development status and support capabilities of the RAT are basically the same between different regions of the same country, a change in the usage scenario is determined based on a change in the country where the terminal device is located.

[0102] For the various services performed by the terminal device, the meaning of a change in the usage scenario is different for different service classification criteria. For example: Different services can be classified into data services and voice services based on the service content. When the service performed by the terminal device changes from a data service to a voice service, a change in the usage scenario can be determined. Another example: Different services can be classified into delay-sensitive services, delay-insensitive services, and high-throughput services based on the service characteristics. When the service performed by the terminal device changes from sending an email (a delay-insensitive service) to a video call (a delay-sensitive service), a change in the usage scenario can be determined.

[0103] It can be understood that users have different usage situations of the terminal device at different times and stages. Different usage situations trigger the terminal device to be in different usage modes, and different usage modes have different requirements for the RAT. For example: During the user's sleep time, the usage frequency of the terminal device is greatly reduced, triggering the terminal device to enter the low-power mode. At this time, it can be determined that the terminal device is in the low-power mode. Another example: Due to the long-term use of the user, the temperature of the terminal device becomes too high and the power consumption is too fast, triggering the low-power mode. At this time, it can also be determined that the terminal device is in the low-power mode. Another example: When the user uses the terminal device during the process of taking the high-speed rail, it can be determined that the terminal device is in the high-speed movement mode.

[0104] In some embodiments, the scenario information includes: Mobile Country Code, and / or service type, and / or usage pattern; based on this, step 103 includes: selecting, from the RAT priority management library corresponding to the Mobile Country Code, the RAT priority information indicated by the Mobile Country Code; and / or, selecting, from the RAT priority management library corresponding to the service type, the RAT priority information indicated by the service type; and / or, selecting, from the RAT priority management library corresponding to the usage pattern, the RAT priority information indicated by the usage pattern.

[0105] In this embodiment, during the movement of the terminal device, a broadcast message will be sent to the relevant network device to inform the current location. The Mobile Country Code is carried in the broadcast message, and based on the Mobile Country Code, the country where the terminal device is located can be determined. Based on the country where the terminal device is located, the RAT priority information corresponding to this country can be selected from the RAT priority management library based on the country. For example: when the Mobile Country Code is "460", it is determined that the country where the terminal device is located is Country A, then it is determined that the RAT priority information corresponding to Country A is NR, LTE (priority order from high to low). Among them, NR (New Radio) is the radio access technology in the 5G network, and LTE (Long Term Evolution) is the radio access technology in the 4G network. Assume that Country A is a country where 2G and 3G networks have been retired. Therefore, the radio access technology GSM (Global System for Mobile Communications) in the 2G network is excluded from the RAT priority information corresponding to Country A, and the radio access technology WCDMA (Wideband Code Division Multiple Access) in the 3G network is also excluded from the RAT priority information corresponding to Country A.

[0106] In addition, when the obtained scenario information is the service type, the RAT priority information corresponding to this service type can be obtained from the RAT priority management library based on the service. For example: when the service type is a video service, the RAT priority information of the video service is obtained.

[0107] When the obtained scenario information is the usage pattern, the RAT priority information corresponding to this usage pattern is obtained from the RAT priority management library based on the usage pattern. For example: when the usage pattern is the low-power mode, the RAT priority information of the low-power mode is obtained.

[0108] It should be noted that the usage of the terminal device by the user is ever-changing. It is possible that the country where the terminal device is located, the services it performs, and the usage mode it is in all change. At this time, the RAT priority information corresponding to the usage scenario with the smallest granularity can be selected for mobility management. It can be understood that setting different RAT priorities based on different countries is a relatively crude method with a large granularity; setting different RAT priorities based on different usage modes is more refined than the method based on countries, but it is still not the most refined setting method; while setting different RAT priorities based on different services is the most refined, with the smallest granularity and the best improvement effect on the user experience.

[0109] In one embodiment, as Figure 2 shown, it includes:

[0110] In step 105, if the RAT priority information indicated by the service type does not exist in the RAT priority management library corresponding to the service type, the preset RAT priority information is selected for mobility management.

[0111] In step 106, during the process of mobility management based on the preset RAT priority information, if the terminal device receives an abnormal information, the RAT priority management library corresponding to the service type is updated based on the abnormal information and the preset RAT priority information; wherein, the abnormal information is used to indicate that at least one RAT in the preset RAT priority information does not support the service indicated by the service type information.

[0112] In this embodiment, the RAT priority information stored in the RAT priority management based on services may not be complete. For some service types, the corresponding RAT priority information of this service type may not be stored. At this time, the preset RAT priority information can be used for mobility management. During the mobility management process, the terminal device sequentially uses the RATs in the preset RAT priority information for handover between radio access technologies, or cell selection, or cell reselection, or re-establishment after radio link failure. During this process, if the terminal device receives abnormal information, such as: the currently used RAT does not support this service type, it means that the preset RAT priority information is not fully adapted to this service type. At this time, the preset RAT priority information can be adjusted based on the abnormal information, and the RAT priority management library based on services is updated accordingly.

[0113] For example, if the preset RAT priority information is GSM, WCDMA, LTE, NR (in descending order of priority), and the service type is an autonomous driving service, then during the execution of the autonomous driving service, GSM is first used for mobility management. At this time, since the autonomous driving service has very high requirements for network quality, network rate, and network latency, the terminal device will receive abnormal information. For example, GSM does not support the autonomous driving service. Then the terminal device will sequentially switch the RAT to WCDMA, LTE, and NR according to the priority order to execute the autonomous driving service. During this process, abnormal information may still be received. Then the terminal device can modify the preset RAT priority information based on the abnormal information so that the modified preset RAT priority information adapts to the autonomous driving service.

[0114] Of course, if the terminal device does not receive abnormal information sent by the relevant network device during the mobility management process, it means that the preset RAT priority information is fully adapted to the service type. Then the preset RAT priority information can be added to the RAT priority management library as the RAT priority information corresponding to the service type.

[0115] In addition, for the RAT priority information existing in the RAT priority management library, during the mobility management process based on this RAT priority information, the information in the RAT priority management library can also be modified based on the feedback abnormal information so that the RAT priority management library meets the actual usage requirements.

[0116] In an embodiment, step 106 includes: making a corresponding adjustment to the preset RAT priority information based on the abnormal type indicated by the abnormal information to obtain the adjusted preset RAT priority information; adding the adjusted preset RAT priority information to the corresponding RAT priority management library.

[0117] In this embodiment, the RAT order in the preset RAT priority information can be modified based on the abnormal type indicated by the abnormal information, or at least one RAT can be deleted. The adjusted preset RAT priority information is added to the service-based RAT priority management library as the RAT priority information of the service type.

[0118] In some embodiments, if the service type is an emergency call service, the RAT priority order indicated by the RAT priority information is NR, WCDMA, GSM from high to low; if the service type is a latency-sensitive service, the RAT priority order indicated by the RAT priority information is NR, LTE, WCDMA, GSM from high to low; if the service type is a latency-insensitive service, the RAT priority order indicated by the RAT priority information is LTE, NR, WCDMA, GSM from high to low.

[0119] In some embodiments, if the usage mode is the low-power mode, the RAT priority order indicated by the RAT priority information is, from high to low, LTE, NR, WCDMA, GSM; if the usage mode is the low-speed movement mode, the RAT priority order indicated by the RAT priority information is, from high to low, NR, LTE, WCDMA, GSM; if the usage mode is the high-speed movement mode, the RAT priority order indicated by the RAT priority information is, from high to low, LTE, WCDMA, NR, GSM.

[0120] In this embodiment, since the emergency call service has the highest level among all service types, therefore, the best-quality 5G network, that is, the RAT is NR, can be set as the highest priority. Similarly, for delay-sensitive services, the priorities of RAT technologies such as NR, LTE, WCDMA, and GSM are also set according to the network quality. In the low-power mode, since NR has a higher terminal power consumption than LTE, LTE is set as the highest priority. In the high-speed movement mode, for example, during the process of taking a high-speed train, since the LTE base station has a larger coverage range than the NR base station, the terminal can often stay on LTE to have a more stable network quality, so LTE is set as the highest priority. In the low-speed movement mode, for example, during the process of riding a bicycle, since the moving speed of the terminal device is not high, NR can be set as the highest priority.

[0121] Of course, the above settings of the RAT priority information are only examples of some embodiments, and due to different consideration factors, the RAT priority information corresponding to the above service types or usage modes can also be in other orders or other RAT technologies.

[0122] As Figure 3 shown, it is a schematic flowchart of mobility management using a country-based RAT priority management library, and its process specifically includes:

[0123] In step 301, configure a country-based RAT priority management library;

[0124] In step 302, determine whether the country where the terminal device is located has changed;

[0125] Among them, if it has changed, execute step 303, if not, end, that is, use the previously used RAT priority information for mobility management.

[0126] In step 303, read the RAT priority information corresponding to the country in the RAT management library;

[0127] In step 304, uniformly overwrite the RAT priority information of all operators in this country;

[0128] In this embodiment, the RAT priority information is used for mobility management for all operators in this country.

[0129] As Figure 4 shown, it is a schematic flowchart of mobility management using a service-based RAT priority management library, and its process specifically includes:

[0130] In step 401, configure a service-based RAT priority management library;

[0131] In step 402, read all RAT priority information corresponding to the operator in the service-based RAT management library;

[0132] In step 403, determine whether the service being executed by the terminal device has changed.

[0133] Among them, if it has changed, then execute step 404; if it has not changed, then end, that is, use the RAT priority information used at the previous moment.

[0134] In step 404, determine whether there is RAT priority information corresponding to the service in the service-based RAT priority management library;

[0135] Among them, if there is, then execute step 405; if there is not, then execute step 407.

[0136] In step 405, read the RAT priority information corresponding to the service in the RAT management library;

[0137] In step 404, perform the service using the corresponding RAT priority information;

[0138] In step 407, perform the service using the preset RAT priority information;

[0139] In step 408, determine whether the terminal device has received an exception message;

[0140] Among them, if an exception message is received, then execute step 409; if no exception message is received, then end.

[0141] In step 409, update to the RAT priority management library;

[0142] In this embodiment, the RAT priority information of each service stored in the service-based RAT priority management library can also be divided according to the affiliated operator. For the same service type, different operators have different corresponding RAT priority information.
