Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a communication method, device, and medium. Background Technology

[0002] Different regions (e.g., Asia, Southeast Asia, Europe, Latin America, etc.) have different frequency band requirements for network deployment. Even with the same band, the frequency range configured for the network within that band may differ. For terminals shipped to different regions (e.g., Southeast Asia, Europe, Latin America, etc.), to meet local network requirements and save hardware costs, the terminals are configured at the factory to support the band of the shipping location network. Terminals configured with a band supporting the shipping location network will not experience any issues within that network. However, when the terminal roams to a location other than the shipping location, the network in that location may continuously configure blind handover cells, blind carrier aggregation (CA), and blind redirection to frequency ranges that the terminal does not support, leading to Radio Link Failure (RLF) and network anomalies. Summary of the Invention

If the first bandwidth portion does not match the first frequency range, a Radio Resource Control (RRC) reconstruction request is sent to the network-side device. The RRC reconstruction request includes a first field and a second field. The first field is used to indicate the frequency band corresponding to the radio link failure, and the second field is used to indicate the first frequency range.

Detailed Implementation

[0015] 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.

[0016] 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 terms can be used interchangeably 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, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0017] The communication methods, devices, and media provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0018] Figure 1 This is a flowchart illustrating a communication method executed by a first terminal according to some embodiments of this application; the communication method executed by the first terminal may include: Step 101: In the event of a wireless link failure in the first terminal, obtain the first bandwidth portion and the first frequency range, wherein the first bandwidth portion is the bandwidth portion configured by the network-side device for the first terminal, and the first frequency range is the frequency range supported by the first terminal; In some embodiments of this application, the first frequency range can be pre-stored in a configuration file for storing the frequency ranges supported by the first terminal. When the first terminal experiences a wireless link failure, the first terminal can obtain the frequency ranges supported by the first terminal from the configuration file.

[0019] In some embodiments of this application, the first frequency range can be the entire frequency range corresponding to a certain frequency band, or it can be a partial frequency range corresponding to a certain frequency band, i.e., a frequency range that does not correspond to the entire frequency band. For example, the first frequency range is the entire frequency range corresponding to the N28A frequency band; the first frequency range is a partial frequency range corresponding to the N41 frequency band, i.e., a frequency range that does not correspond to the entire N41 frequency band.

[0020] In some embodiments of this application, the first terminal can obtain the first bandwidth portion configured by the network-side device for the first terminal from the radio resource control signaling sent by the network-side device.

[0021] Step 102: If the first bandwidth portion does not match the first frequency range, send a radio resource control reconstruction request to the network-side device. The radio resource control reconstruction request includes a first field and a second field. The first field is used to indicate the frequency band corresponding to the radio link failure, and the second field is used to indicate the first frequency range.

[0022] In some embodiments of this application, when all or part of the first bandwidth portion is not within the first frequency range, it indicates that the first bandwidth portion does not match the first frequency range; when the first bandwidth portion is entirely within the first frequency range, it indicates that the first bandwidth portion matches the first frequency range.

[0023] For example, the first frequency range is the entire frequency range corresponding to the N41 band, wherein the entire frequency range corresponding to the N41 band is from 2496 MHz to 2690 MHz. When the bandwidth configured by the network-side device for the first terminal is from 3400 MHz to 3600 MHz, the first bandwidth portion does not match the first frequency range.

[0024] For example, the first frequency range is the entire frequency range corresponding to the N41 band. When the bandwidth configured by the network-side device for the first terminal is 2550 MHz to 2750 MHz, the first bandwidth does not match the first frequency range.

[0025] For example, the first frequency range is the entire frequency range corresponding to the N41 band. When the bandwidth configured by the network-side device for the first terminal is 2550 MHz to 2600 MHz, the first bandwidth portion matches the first frequency range.

[0026] When the frequency range supported by the first terminal does not match the first bandwidth portion configured for the first terminal by the network-side device, the first terminal sends a radio resource control reconstruction request to the network-side device, and indicates the frequency band corresponding to the radio link failure and the first frequency range supported by the terminal in the radio resource control reconstruction request, so as to avoid the network-side device configuring the first bandwidth portion for the first terminal again, causing the first terminal's radio link to fail.

[0027] In some embodiments of this application, the first field and the second field in the embodiments of this application may be fields newly added in the Radio Resource Control Reconstruction Request.

[0028] In some embodiments of this application, the Radio Resource Control (RRC) rebuild request may include a rebuild cause (ReestablishmentCause), which may include a rebuild configuration failure (reconfigurationFailure) field, a handover failure (handoverFailure) field, and other failure fields (otherFailure). A first field and a second field may be added under the reconfigurationFailure field, with the value of the first field assigned to the frequency band corresponding to the radio link failure, and the value of the second field assigned to a first frequency range.

[0029] For example, the first field added under the reconfigurationFailure field is the band field, and the second field is the (f1, f2) field, where f1 is used to represent the start frequency of the first frequency range, and f2 is used to represent the end frequency of the first frequency range; assuming that the frequency band corresponding to the wireless link failure is the N28A band, and the first frequency range is 2496 MHz to 2690 MHz, then the value of the band field is N28A, and the value of the (f1, f2) field is (2496MHz, 2690 MHz).

[0030] In this embodiment, when a wireless link failure occurs in the first terminal, the first terminal obtains the first bandwidth portion configured by the network-side device and the first frequency range supported by the first terminal. If the first bandwidth portion and the first frequency range do not match, the first terminal sends a radio resource control reconstruction request to the network-side device. The radio resource control reconstruction request indicates the frequency band corresponding to the wireless link failure and the first frequency range supported by the terminal. This can prevent the network-side device from reconfiguring the first bandwidth portion for the first terminal, which would cause the first terminal to experience another wireless link failure and network anomaly. This can solve the problem of network anomalies caused by the terminal not supporting a certain frequency band.

[0031] In some embodiments of this application, when the first bandwidth portion matches the first frequency range and the first terminal experiences a wireless link failure, it indicates that the wireless link failure of the first terminal is not caused by the bandwidth portion configured for the first terminal by the network-side device, but by other reasons, such as hardware failure of the first terminal, IP address conflict, or weak communication signal. In this case, a wireless resource control reconstruction request including the first field and the second field mentioned above may not be sent to the network-side device, but a wireless resource control reconstruction request excluding the first field and the second field mentioned above may be sent to the network-side device.

[0032] In some embodiments of this application, the radio resource control reconstruction request is also used to instruct the network-side device not to configure a first bandwidth portion for the second terminal, which is the same model as the first terminal.

[0033] In some embodiments of this application, the Radio Resource Control (RRC) Reset Request can also be used to instruct the network-side device not to configure the first bandwidth portion for terminals with the same model as the first terminal. When the network-side device receives the RRC Reset Request, it does not configure the first bandwidth information for the first terminal, nor does it configure the first bandwidth portion for terminals with the same model as the first terminal, thus preventing the first terminal from experiencing another radio link failure and preventing terminals with the same model as the first terminal from experiencing radio link failures in blind handover, blind carrier aggregation, and blind redirection scenarios.

[0034] In some embodiments of this application, the radio resource control reconstruction request further includes a third field, which is used to indicate the model information of the first terminal.

[0035] In some embodiments of this application, a first field, a second field, and a third field can be added under the reconfigurationFailure field, and the value of the first field can be assigned to the frequency band corresponding to the wireless link failure, the value of the second field can be assigned to the first frequency range, and the value of the third field can be assigned to the model of the first terminal.

[0036] For example, the first field added under the reconfigurationFailure field is the band field, the second field is the (f1, f2) field, and the third field is the Terminal model; where f1 is used to represent the start frequency of the first frequency range, and f2 is used to represent the end frequency of the first frequency range; assuming that the frequency band corresponding to the wireless link failure is the N28A band, the first frequency range is 2496 MHz to 2690 MHz, and the model of the first terminal is XXXX; then the value of the band field is N28A, the value of the (f1, f2) field is (2496MHz, 2690 MHz), and the Terminal model field indicates XXXX.

[0037] In some embodiments of this application, the communication method performed by the first terminal provided in the embodiments of this application may further include: disabling the frequency bands corresponding to the first bandwidth portion and the second bandwidth portion when the first terminal experiences another wireless link failure and the second bandwidth portion configured by the network-side device for the first terminal again does not match the first frequency range.

[0038] In some embodiments of this application, when the first terminal experiences another wireless link failure and the second bandwidth portion configured by the network-side device for the first terminal again does not match the first frequency range, it indicates that the network-side device has not configured the bandwidth portion according to the first frequency range supported by the first terminal. In this case, the frequency bands corresponding to the first and second bandwidth portions are disabled for a period of time. After the duration of disabling the first and second bandwidth portions reaches the specified time, network access is re-established based on the bandwidth portion configured by the network-side device for the first terminal. When the first terminal experiences a wireless link failure, the frequency range supported by the first terminal and the bandwidth portion configured by the network-side device for the first terminal are re-acquired. When the frequency range supported by the first terminal and the bandwidth portion configured by the network-side device for the first terminal do not match, a radio resource control (RFC) reconstruction request is sent to the network-side device, indicating the frequency band corresponding to the wireless link failure and the first frequency range supported by the terminal in the RRC reconstruction request.

[0039] In some embodiments of this application, when the network-side device reconfigures the bandwidth portion for the first terminal and the first terminal does not experience a wireless link failure, it indicates that the network-side device configures the bandwidth portion according to the first frequency range supported by the first terminal.

[0040] Figure 2 This is a schematic diagram of the overall flow of a communication method executed by a first terminal according to some embodiments of this application. The overall flow of the communication method executed by the first terminal includes the following steps: Step 201: In the event of a wireless link failure in the first terminal, the first terminal obtains the first bandwidth portion configured by the network-side device for the first terminal and the first frequency range supported by the first terminal; Step 202: The first terminal determines whether the first bandwidth portion and the first frequency range match; if yes, proceed to step 203; if no, proceed to step 204. Step 203: The first terminal determines that the wireless link failure of the first terminal is not caused by the bandwidth portion configured for the first terminal by the network-side device; Step 204: The first terminal determines that the wireless link failure of the first terminal is caused by the bandwidth portion configured for the first terminal by the network-side device; Step 205: The first terminal sends a radio resource control re-establishment request to the network-side device. The radio resource control re-establishment request includes a first field, a second field, and a third field. The first field is used to indicate the frequency band corresponding to the radio link failure, the second field is used to indicate the first frequency range, and the third field is used to indicate the model information of the first terminal. Step 206: The first terminal obtains the second bandwidth portion reconfigured for the first terminal by the network-side device; Step 207: In the event of a wireless link failure in the first terminal, the first terminal determines whether the second bandwidth portion matches the first frequency range; if yes, the process ends; otherwise, proceed to step 208. Step 208: The first terminal disables the frequency bands corresponding to the first bandwidth portion and the second bandwidth portion.

[0043] In some embodiments of this application, when a first terminal experiences a wireless link failure, the first terminal obtains a first bandwidth portion configured by the network-side device and a first frequency range supported by the first terminal, and matches the first bandwidth portion with the first frequency range. When the first bandwidth portion does not match the first frequency range, the first terminal sends a Radio Resource Control (RRC) reconstruction request to the network-side device. The RRC reconstruction request includes a first field and a second field. After receiving the RRC reconstruction request, the network-side device configures a bandwidth portion for the first terminal according to the first frequency range indicated by the second field, and does not configure the frequency range corresponding to the frequency band where the first terminal experienced a wireless link failure as indicated by the first field.

[0044] In some embodiments of this application, the radio resource control reconstruction request is also used to instruct the network-side device not to configure a first bandwidth portion for the second terminal, wherein the second terminal is the same model as the first terminal.
