Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a QoS wireless bearing method. Fig. 1 is a first flowchart illustrating a QoS radio bearer method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: the terminal obtains the radio bearer information of the unlicensed frequency band.
Step 102: and monitoring the radio bearer corresponding to the radio bearer information, and discarding the radio bearer information according to a monitoring result or updating the original radio bearer information into the radio bearer information.
In this embodiment, before the terminal obtains the radio bearer information of the unlicensed frequency band, the terminal performs data (such as QoS flow) transmission based on the configured radio bearer, where the configured radio bearer is denoted as an original radio bearer, and the radio bearer information corresponding to the original radio bearer is denoted as original radio bearer information. The terminal obtains the original radio bearer information, wherein the original radio bearer information can comprise an original radio bearer and a mapping relation of data to be transmitted (QoS flow) to the original; the terminal obtains the radio bearer information in this embodiment, where the radio bearer information may include a mapping relationship between a radio bearer and data to be transmitted, and the terminal caches the radio bearer information (i.e., the mapping relationship).
In an optional embodiment of the present application, the obtaining, by the terminal, radio bearer information in an unlicensed frequency band includes: the terminal obtains radio bearer information configured by the network equipment, and determines that the radio bearer corresponding to the radio bearer information works in an unauthorized frequency band based on the specific identifier.
In this embodiment, the terminal obtains configuration information of a radio bearer corresponding to the radio bearer information, where the configuration information is used to indicate whether the radio bearer operates in an unlicensed frequency band, that is, to indicate whether the radio bearer needs to monitor (i.e., LBT) before transmitting data. As an example, the network device indicates, by using a specific identifier, whether the radio bearer operates in an unlicensed frequency band, that is, indicates, by using the specific identifier, whether the radio bearer needs to listen (i.e., LBT) before transmitting data.
In an optional embodiment of the present application, the determining that the radio bearer information operates in an unlicensed frequency band based on the specific identifier includes: the terminal obtains a special signaling or channel associated signaling of the network equipment, and determines that the radio bearer corresponding to the radio bearer information works in an unauthorized frequency band based on a specific identifier of the special signaling or the channel associated signaling.
In this embodiment, the network device indicates, through a specific identifier carried in a dedicated signaling or a channel associated signaling, whether the corresponding radio bearer operates in an unlicensed frequency band. The dedicated signaling may be, for example, Service Data Attachment Protocol (SDAP) Protocol signaling. The channel associated signaling is used as a signaling mode for transmitting signaling and voice in the same voice channel. The specific identifier may be an identifier of any existing field in the dedicated signaling or the associated signaling; alternatively, the specific identifier may also be an identifier of a newly added field in the dedicated signaling or the associated signaling.
In an optional embodiment of the present application, the determining that the radio bearer information operates in an unlicensed frequency band based on the specific identifier of the dedicated signaling or the associated signaling includes: determining that the radio bearer corresponding to the radio bearer information works in an unlicensed frequency band based on at least 1-bit specific identifier in the dedicated signaling or associated signaling; or, determining an unlicensed frequency band in which a radio bearer corresponding to the radio bearer information operates based on at least 1-bit specific identifier in the dedicated signaling or associated signaling.
As the first implementation manner, the network device may indicate, through a specific identifier of at least 1 bit in the dedicated signaling or the associated signaling, whether the radio bearer corresponding to the radio bearer information operates in the unlicensed frequency band. For example, as shown in the bold part of the following code, it is indicated by 1 bit whether the radio bearer operates in the unlicensed frequency band. For example, if the bit position is "1", it may indicate that the radio bearer operates in the unlicensed frequency band, and if the bit position is "0", it may indicate that the radio bearer operates in the licensed frequency band.
As the second implementation manner, the network device may further indicate the unlicensed frequency band in which the radio bearer operates through a specific identifier of at least 1 bit in the dedicated signaling or the associated signaling. For example, as shown in the bold portion of the following code, each bit of the multiple bits may respectively indicate an unlicensed frequency band, and for example, values f1, f2, f3, etc. in the bits may respectively indicate the unlicensed frequency band.
If the bit of at least 1 bit is an existing bit in the signaling, whether the radio bearer operates in the unlicensed frequency band can be indicated by a specific value of the bit of at least 1 bit, where the specific value is a value that is not configured to the bit of at least 1 bit. If the bit of at least 1 bit is a newly added bit in the signaling, it can indicate whether the radio bearer operates in the unlicensed frequency band through a specific value of the bit of at least 1 bit, and the specific value can be determined in a predetermined or preconfigured manner.
In this embodiment, the terminal monitors the radio bearer corresponding to the radio bearer information, that is, performs LBT on the radio bearer, and discards the radio bearer information according to a monitoring result, or updates the original radio bearer information to the radio bearer information. The monitoring of the radio bearer is to monitor whether a channel is occupied or not to determine whether the channel is transmitting data, so as to avoid channel collision. As an example, the radio bearer is monitored, specifically, whether the radio bearer has data transmission is monitored; if there is no data transmission, it can indicate that the radio bearer is idle, and also can indicate that the monitoring is successful; if there is data transmission, it may indicate that the radio bearer is busy, or it may indicate that the listening was not successful (or failed).
In an optional embodiment of the present application, the method further comprises: the terminal obtains monitoring configuration parameters; the monitoring the radio bearer corresponding to the radio bearer information includes: and monitoring the radio bearer corresponding to the radio bearer information based on the monitoring configuration parameters.
In this embodiment, the monitoring configuration parameters include: a duration threshold and/or a number of times threshold; the monitoring the radio bearer corresponding to the radio bearer information based on the monitoring configuration parameters includes: monitoring the radio bearer corresponding to the radio bearer information, and judging whether the monitoring is successful within the duration of the duration threshold value; or, monitoring the radio bearer corresponding to the radio bearer information, and judging whether the number of times of unsuccessful monitoring exceeds the number threshold value; or monitoring the radio bearer corresponding to the radio bearer information, and judging whether the times of unsuccessful monitoring within the duration of the duration threshold value exceed the times threshold value.
As a first implementation manner, when determining that the radio bearer operates in the unlicensed frequency band, the terminal starts a timer, where a timing duration of the timer is the duration threshold. Monitoring a radio bearer based on the timing duration of the timer; if the radio bearer is monitored to be idle before the timing duration of the timer is reached, the monitoring result is successful; if the radio bearer is not monitored to be idle when the timing time of the timer is up, the monitoring result is the monitoring failure.
As a second implementation manner, when the terminal determines that the radio bearer operates in the unlicensed frequency band, a counter is started, and the radio bearer is monitored; if the idle state of the radio bearer is not monitored, it indicates that one monitoring fails, the counting value of the counter is increased by one, and the monitoring of the radio bearer is repeated. If the count value of the counter reaches the frequency threshold value, the monitoring result is a monitoring failure; otherwise, if the counting value does not reach the frequency threshold value, the monitoring result is successful.
As a third implementation manner, when the terminal determines that the radio bearer operates in the unlicensed frequency band, a timer and a counter are started at the same time; the timing duration of the timer is the duration threshold value; monitoring the radio bearer within the timing duration of the timer; if the idle state of the radio bearer is not monitored, indicating that one monitoring fails, adding one to the count value of the counter, and repeatedly monitoring the radio bearer; when the timing time of the timer is up, if the count value of the counter exceeds the frequency threshold value, the monitoring result is a monitoring failure; if the counting value of the counter does not exceed the frequency threshold value, the monitoring result is successful.
In an optional embodiment of the present application, the method further comprises: the terminal obtains the monitoring configuration parameters from the network equipment through broadcast messages or special signaling; or, the terminal obtains the monitoring configuration parameters by adopting a pre-agreed mode.
Based on this, as shown in fig. 2, step 102 in this embodiment may include:
step 102 a: and if the monitoring result is monitoring failure, discarding the radio bearer information.
In this embodiment, the listening result is a listening failure, which includes: if the monitoring is not successful within the duration of the duration threshold value; or, if the number of times of unsuccessful monitoring exceeds the threshold value; or, if the number of times of unsuccessful monitoring within the duration of the duration threshold exceeds the number threshold, determining that the monitoring result is a monitoring failure.
In this embodiment, if the monitoring result is a monitoring failure, which indicates that the radio bearer cannot perform data transmission, the radio bearer information is discarded, and data transmission is performed based on the radio bearer corresponding to the original radio bearer information.
Alternatively, as shown in fig. 2, step 102 in this embodiment may include:
step 102 b: and if the monitoring result is successful monitoring, updating the original radio bearer information into the radio bearer information.
In this embodiment, the listening result is a successful listening, including: if the monitoring is successful within the duration of the duration threshold value; or, if the number of times of unsuccessful monitoring does not exceed the threshold value of the number of times; or, if the number of times of unsuccessful monitoring in the duration of the duration threshold does not exceed the number threshold, determining that the monitoring result is successful monitoring.
In this embodiment, if the monitoring result is successful, which indicates that the radio bearer is idle and data transmission is possible, the original radio bearer information is replaced with the radio bearer information, and after the data transmission corresponding to the original radio bearer information is completed, the original radio bearer is released.
In an optional embodiment of the present application, the terminal sends an indication message to the network device; the indication information represents that the radio bearer information is discarded or updated.
In this embodiment, no matter the terminal discards the radio bearer information or replaces the original radio bearer information with the radio bearer information, the terminal may send the indication information to the network device through the identifier of at least 1 bit. The at least 1 bit identifier is used for informing that the radio bearer information of the network equipment terminal is updated or informing that the radio bearer information of the network equipment terminal is not updated.
By adopting the technical scheme of the embodiment of the invention, the terminal monitors the radio bearer of the newly configured unauthorized frequency band, discards the radio bearer information according to the monitoring result and continues to use the original radio bearer for data transmission, or updates the original radio bearer into the newly configured radio bearer so as to use the newly configured radio bearer for data transmission, thereby avoiding data transmission delay or failure in transmission due to failure in monitoring and release of the original radio bearer of the configured radio bearer, greatly reducing the data transmission delay of the radio bearer of the unauthorized frequency band, and improving the reliability of data transmission.
The QoS radio bearer method according to the embodiment of the present invention is described in detail below with reference to specific embodiments. Fig. 3 is a third flowchart illustrating a QoS radio bearer method according to an embodiment of the present invention; as shown in fig. 3, the method includes:
step 201: and the network equipment indicates whether the radio bearer A configured for the QoS flow by the terminal works in an unauthorized frequency band or not.
Here, the network device may indicate whether the radio bearer a operates in the unlicensed frequency band through a specific identifier of at least 1 bit. The network device may indicate, through dedicated signaling or associated signaling, whether the radio bearer a configured for QoS flow by the terminal operates in the unlicensed frequency band. Wherein whether to operate in the unlicensed frequency band identifies whether LBT is required prior to data transmission.
Step 202: and the terminal determines that the radio bearer A works in an unauthorized frequency band according to the indication of the network equipment, and starts a timer and/or a counter.
Step 203: the terminal keeps the mapping relation (original mapping relation) between the radio bearer B and the QoS flow1, temporarily stores the mapping relation (new mapping relation) between the radio bearer A and the QoS flow, and performs LBT in the working frequency band of the radio bearer A.
Here, the terminal may perform the determination whether LBT is successful in the following manner:
1. carrying out LBT on the radio bearer A based on the timing duration of the timer, and if the radio bearer A is monitored to be idle before the timing duration of the timer is reached, indicating that the monitoring result is successful; if the idle radio bearer A is not monitored when the timing time of the timer is up, indicating that the monitoring result is monitoring failure;
2. performing LBT on a radio bearer A; if the radio bearer A is not monitored to be idle, indicating that one monitoring fails, adding one to the count value of the counter, and repeatedly monitoring the radio bearer A; if the count value of the counter reaches the frequency threshold value, the monitoring result is a monitoring failure; otherwise, if the counting value does not reach the frequency threshold value, the monitoring result is that the monitoring is successful;
3. carrying out LBT on a radio bearer A based on the timing duration of the timer, if the radio bearer A is not monitored to be idle, indicating that monitoring fails once, adding one to the count value of the counter, and repeatedly carrying out monitoring on the radio bearer A; when the timing time of the timer is up, if the count value of the counter exceeds the frequency threshold value, the monitoring result is a monitoring failure; if the counting value of the counter does not exceed the frequency threshold value, the monitoring result is successful.
In this embodiment, before LBT is successful, the mapping relationship (original mapping relationship) between the radio bearer B and the QoS flow1 is maintained, and an End Marker (End Marker) is not sent on the radio bearer B.
Step 204 a: if the LBT is successful, the terminal updates the mapping relationship (original mapping relationship) between the radio bearer B and the QoS flow1 to the mapping relationship (new mapping relationship) between the radio bearer a and the QoS flow, and releases the timer and/or the counter.
Step 204 b: if LBT fails, the terminal discards the mapping relation (new mapping relation) between the radio bearer A and the QoS flow, and transmits the QoS flow by using the working frequency band of the radio bearer B.
Step 205: and the terminal sends indication information to the network equipment, wherein the indication information is used for indicating that the mapping relation is successfully updated or not updated.
Here, the terminal may indicate that the mapping relation update is successful or the mapping relation is not updated through an identification of at least 1 bit.
In this embodiment, because the authorized Spectrum resources are limited, in order to meet the service requirements of seamless coverage and high data rate (large bandwidth), the 4G/5G mobile network considers providing access services in an Unlicensed Spectrum (e.g., 2.4GHz, 3.5GHz, and 5 GHz). Due to the unlicensed nature of unlicensed spectrum, mobile network deployment faces two major challenges: the channel occupancy rate is high, the interference is serious, and the quality of an air interface is difficult to guarantee; some countries or regions (e.g., european union, japan) require channel occupancy monitoring before any communication is performed in the unlicensed spectrum, i.e., LBT, which is successful before communication can be performed. It can be seen that LBT failure will affect any over-the-air communication in the mobile network protocol. For example, when LBT fails on a certain DRB, user data cannot be sent on the DRB, resulting in delay or failure of reception on the network side or the terminal side.
However, the current SDAP layer protocol defines that when the network device configures the mapping from QoS flow to DRB for the terminal, the terminal should adopt the newly configured mapping relationship and cover the original mapping relationship. If the newly configured DRB works in the unlicensed frequency band, LBT needs to be performed before sending the corresponding QoS flow; if the LBT fails, the QoS flow transmission cannot be performed.
By adopting the technical scheme of the embodiment of the invention, the terminal monitors the radio bearer of the newly configured unauthorized frequency band, discards the radio bearer information according to the monitoring result and continues to use the original radio bearer for data transmission, or updates the original radio bearer into the newly configured radio bearer so as to use the newly configured radio bearer for data transmission, thereby avoiding data transmission delay or failure in transmission due to failure in monitoring and release of the original radio bearer of the configured radio bearer, greatly reducing the data transmission delay of the radio bearer of the unauthorized frequency band, and improving the reliability of data transmission.
