Description

Time information processing method, timing advance determining method and related equipment

Technical Field

The present invention relates to mobile communication technologies, and in particular, to a method for processing time information, a method for determining timing advance, and a related device.

Background

Existing Time Sensitive Networks (TSNs) support real-Time control and synchronization over an ethernet Network, for example between motion applications and robots. The TSN may also support other data communications common in manufacturing applications, facilitating convergence between Information Technology (IT) and Operational Technology (OT). With the data of the industrial internet of things causing the network to become more and more congested, how the TSN ensures that the data can be normally communicated so that the industrial internet of things can help users is a current concern. While much of the data collected by industrial sensors and control systems in the industrial internet of things is not time sensitive, there are also a large number of mission critical, time sensitive data that must be transmitted and shared within strict bounds of delay and reliability. Such as a universal clock for transmission scheduling, delay specification, reserved bandwidth, and redundancy configuration, this requirement for TSNs enables the TSNs to ensure accuracy of time synchronization, thereby supporting synchronization of multiple data streams. Large data sets from machine vision, three-dimensional (3D, 3Dimensions) scanning, and power efficiency analysis may place a burden on network bandwidth. Existing TSNs support full duplex standard ethernet using higher bandwidth options including 1Gb, 10Gb, and even 400Gb versions of IEEE 802.3. IT will also provide top level IT security provisions and interoperability, as well as scalability that can grow to large scale systems.

Meanwhile, the timing of the wireless network in mobile communication often depends on a Global Navigation Satellite System (GNSS). GNSS generally refers to all Satellite Navigation systems including global, regional, and Augmentation, such as the GPS in the united states, the beidou Satellite Navigation System in china, and related Augmentation systems, such as the Wide Area Augmentation System (WAAS) in the united states, the European Geostationary Navigation Overlay System (EGNOS) in europe, the Multi-Functional Satellite Augmentation System (MSAS) in japan, and the like, as well as other Satellite Navigation systems under construction and later to be built.

When the TSN service passes through the 5G system instead of the network cable, the TSN network system has a clock, and the TSN service specifically requires more strict delay and jitter control than the conventional 5G service; therefore, it is desirable to provide a method capable of accurately determining a delay budget in a 5G system, so as to overcome instability of an air interface and make an efficient and accurate wireless scheduling decision.

Specifically, the UE may read a transmission time point Tm (time sent from the 5G system) of a certain data packet (e.g., data packet a) obtained by the device through its own interpretation function module (e.g., for the TSN network, the UE may utilize its own TSN interpretation function module). The sending time information comprises at least one of the following:

Step 302, the UE sends the determined sending time information to the base station.

Here, the UE sends the sending time information to the base station through PDCP data or SDAP data, and carries the sending time information in a payload (payload) of the PDCP data or SDAP data, where a header of the PDCP data or SDAP data carries a specific identifier indicating that the sending time information is carried; or, the sending time information is carried in a header of the PDCP data or the SDAP data.

Specifically, the UE sends the sending time information to a lower layer, which may be an SDAP layer or a PDCP layer; taking PDCP as an example, the UE side encapsulates the sending time information in payload of the PDCP, gives a specific identifier in the header of the PDCP and then sends the specific identifier to the base station; or, the transmission time information is directly indicated in a header of the PDCP packet data and transmitted to the base station. The base station may interpret the transmission time information, select a suitable time point according to the transmission time information and a predetermined first time delay, and transmit the packet a to a downstream node, such as a UPF, an adjacent base station, a core network, or the like, according to the selected time point.

Further, the SDAP or PDCP layer of the UE may inform the MAC layer of the sending time information and the identifier of the corresponding data packet, such as a Sequence Number (SN) through an internal message (e.g., a primitive); the MAC layer selects a proper SPS/CG resource for the data packet A according to the party time information, wherein the SPS/CG resource is used for sending the PDCP data or the SDAP data to a first communication node;

And the BSR requests the corresponding MAC CE to be the MAC CE with a preset format.

Here, the UE may also send a time status report message, which carries the sending time information of one or more data packets, the identifier of the data packet, and the like; the sending time information of the data packet may be time data, or time indication information (e.g., time information with coarse mapping granularity or time information indicating a certain range by several bits); the time status report information may be RLC, PDCP, SDAP, and/or RRC control signaling.

Step 303, after receiving the sending time information, the base station performs uplink scheduling resource allocation according to the information.

For example, the allocation of transmission resources for the corresponding packets is adjusted based on the transmission time information. Specifically, the base station may interpret the transmission time information, select an appropriate time point according to the transmission time information and a predetermined first time delay, and transmit the packet a to a downstream node, such as a UPF, an adjacent base station, a core network, or the like, according to the selected time point.

An embodiment of the present invention provides a method for processing time information, which is specifically used for a core network device to send a data packet to a base station (i.e., to send downlink data), and the method includes:

step 401, the core network determines the sending time information.

Specifically, the core network reads a transmission time point Tm of a certain data packet (e.g., data packet a) obtained by the device through the TSN reading function module; here, the Tm specifically refers to a time point of departure from the 5G network. Wherein the determined transmission time information may include at least one of:

sending a time point Tm;

Tm-Tc; wherein, Tc represents the time delay of RAN and UE acquired by UPF;

a range of values related to Tm-Tc, such as from Tm-Tc-Tdelta3 to Tm-Tc + Tdelta3, said Tdelta3 characterizing a third offset value;

another range of values associated with Tm-Tr: the Tdelta4 characterizes the fourth offset value from Tm-Tc-Tr-Tdelta4 to Tm-Tc-Tr + Tdelta 4.

It should be noted that the time delay Tc of the RAN and the UE may be predetermined, and is specifically shown in the following embodiments five, six, seven, and eight.

Step 402, the core network device (e.g. UPF) sends the sending time information of the data packet a to the base station.

Specifically, after acquiring the sending time information, the core network device sends the sending time information to a lower layer, the lower layer is an SDAP layer or a PDCP layer, taking the PDCP as an example, the base station encapsulates the sending time information in payload of the PDCP, gives a specific identifier in the header of the PDCP, and sends the specific identifier to the base station; or, the transmission time information is directly indicated in a header of the PDCP packet data and transmitted to the base station.

Here, the SDAP or PDCP layer of the core network device informs the MAC layer of the transmission time information and an identifier (e.g., SN number) of the corresponding data packet through an internal message (e.g., primitive); and selecting proper SPS/CG resources for the data packet by the MAC layer according to the information.

Here, the UPF determines at least one of the scheduling order of the downlink data, the order of multiplexing the logical information, or the priority based on the transmission time information, in addition to the priority.

Step 403, after reading the sending time information, the base station selects a suitable time point according to the sending time information, and sends the data packet a to a downstream node, such as other UPFs, neighboring base stations, UE, and the like.

Specifically, the base station selects a suitable time point according to the sending time information and a predetermined first time delay, and sends the data packet a to a downstream node according to the selected time point, where downstream may include: UPF, neighboring base stations, core network, etc.

An embodiment of the present invention provides a method for a base station to determine a first time delay, where the method includes:

step 501, the base station sends a request for determining the time delay to the UE.

Step 502, the UE sends a test data packet to the base station according to the determined delay request.

Here, the UE may read TSN clock information obtained by the device through the TSN interpretation function module and transmit the TSN clock information to the base station.

For example, the test packets may include: TSN clock information; the UE sends the TSN clock information to the lower layer, and if the lower layer is the RRC layer, the UE sends the TSN clock information (denoted as a first message) to the base station.

Step 503, the UE sends the time point of sending the TSN clock information to the base station.

Step 504, after receiving the first message, the base station replies a message (denoted as a second message), where the second message carries a time point of receiving the first message (specifically, as shown in fig. 3, the time point is T1 in fig. 3).

And step 505, the base station sends a third piece of information to the UE, where the message carries a time point T2 for sending the second message.

Step 507, the UE sends a fourth message to the base station, where the fourth message includes: the UE calculates the round trip delay (T1-T0+ T3-T2) to the base station, and the message also carries the T3 time point.

And 507, the base station uses the calculated round-trip transmission delay (T1-T0+ T3-T2) sent by the UE, obtains the processing delay of the UE by using the arrival time Tr of the T0-data packet, and determines the synchronization time point corresponding to the TSN according to the TSN clock information.

Specifically, the sum of the transmission delay and the processing delay determined by the base station is the first delay. And, the base station may calculate its own synchronization clock (i.e., synchronization time point) corresponding to the TSN network according to the TSN persistent information.

The method may further comprise: step 509, the base station initiates a delay determination request when the UE starts to determine at multiple time points, and the base station smoothes the calculation result in a certain time period to ensure the applicability of the calculation process.

The method may further comprise: step 510, after a certain period of time, the base station initiates a delay updating request.

It should be noted that the base station may update the time delay according to a preset period; wherein the value of the period is associated with the accuracy and/or granularity of the time delay. Or, the base station may update the delay when determining that at least one of the following conditions is satisfied: the variation of the wireless channel quality/received power measured by the UE and/or the base station reaches a first preset threshold; the position of the UE is not at a preset position; the data buffer amount of the base station reaches a second preset threshold; the utilization rate of the PRB reaches a third preset threshold; the number of the UE in the connected state in the network coverage range of the base station reaches a fourth preset threshold; the time delay of the data packet reaches a fifth preset threshold; wherein, the time delay of the data packet can be further divided into the buffering time and the scheduling time of the data; the data loss rate reaches a sixth preset threshold; the throughput of the dispatched IP reaches a seventh preset threshold; the DL/UL data volume reaches an eighth preset threshold; the PRB utilization rate exceeds a ninth preset threshold. The first preset threshold, the second preset threshold … … and the ninth preset threshold may be preset and stored.

step 601, the base station sends a request for TSN clock information to the UE.

Step 602, after receiving the request, the UE reads the TSN clock information obtained by the device through its own TSN interpretation function module and sends the TSN clock information to the base station.

Specifically, the UE sends a first message to the base station, where the first message includes: TSN clock information, and the message I carries the time point Tr when the TSN clock information reaches the UE.

Step 603, the UE sends the time point T0 of sending the TSN clock information to the base station.

And step 604, after receiving the first message, the base station determines the current TA through the first message.

It should be noted that the UE may trigger TA update in advance, that is, request the base station to send the TA in advance.

605, the base station calculates the transmission delay between the base station and the UE by using the TA, and obtains the processing delay of the UE, i.e. T0-Tr, according to T0 and Tr; in addition, the base station can determine its own synchronization time point according to the TSN clock information.

Through the above steps, the base station obtains TSN clock information from the UE, and calculates a synchronization clock (synchronization time point) corresponding to the TSN network.

The method may further comprise: step 607, the base station initiates a delay determination request when the UE starts up at a plurality of time points, and the base station smoothes the calculation result of a certain time period to ensure the applicability of the calculation process.

The method may further comprise: step 608, after a certain period of time, the base station initiates a delay updating request. The base station can update the time delay according to a preset period; wherein the value of the period is associated with the accuracy and/or granularity of the time delay. Or, the base station may update the delay when determining that at least one of the following conditions is satisfied: the variation of the wireless channel quality/received power measured by the UE and/or the base station reaches a first preset threshold; the position of the UE is not at a preset position; the data buffer amount of the base station reaches a second preset threshold; the utilization rate of the PRB reaches a third preset threshold; the number of the UE in the connected state in the network coverage range of the base station reaches a fourth preset threshold; the time delay of the data packet reaches a fifth preset threshold; wherein, the time delay of the data packet can be further divided into the buffering time and the scheduling time of the data; the data loss rate reaches a sixth preset threshold; the throughput of the dispatched IP reaches a seventh preset threshold; the DL/UL data volume reaches an eighth preset threshold; the PRB utilization rate exceeds a ninth preset threshold.

For example, the UE may parse the TAC to obtain TA0, and calculate the time size of TA. As shown in the uplink and downlink transmission time relationship diagram of fig. 4, N _ TA is a measurement value analyzed by the UE according to the TAC; n _ TA and offset are fixed values that vary according to different frequency bands and subcarrier intervals, and specific values may refer to values in a relevant protocol.
