Description

Information transmission method, device, related equipment and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to an information transmission method, apparatus, related device, and storage medium.

Background

In a sixth generation mobile communication technology (6G) protocol stack, an intelligent Plane (AI Plane) and a Data Plane (Data Plane) are introduced, and these two planes are generated into a Control Plane (Control Plane) and a User Plane (User Plane) of the protocol stack, so as to implement a per-User Equipment (UE) of the protocol stack and a protocol stack function Service (english may be expressed as Service) required for Service transmission of the UE, thereby implementing a flexible network. Flexibility refers to configuring different protocol stack functions according to the needs of a user (e.g., quality of service (QoS) requirements, traffic type requirements, slice types, etc.), and providing the protocol stack functions to the user in the form of "services". The functions within the "service" itself may be defined by the receiver and sender as implemented by itself, such as a correlation model or algorithm of Artificial Intelligence (AI), correlation processing of data planes, etc.

Where the provision of the protocol stack functionality to the user in the form of "services" refers to the protocol stack functionality servicing (SOF, service Oriented Function). In other words, the flexibility of the 6G protocol stack (such as function on-demand selection, low unified redundancy overhead of Protocol Data Unit (PDU) format, no connection or light connection between protocol layers, on-demand application of protocol functions in service form, etc.) needs to break through the fifth generation mobile communication technology (5G) protocol stack scheme to perform design for 6G, so as to implement SOF of the protocol stack functions, thereby implementing a flexible network.

Detailed Description

The present application will be described in further detail with reference to the accompanying drawings and examples.

In various embodiments of the present application, the random access response carries information of the link between L2 and L3, and the network side configures the link between L2 and L3 through the random access response, so that the terminal can complete RRC registration without establishing SRBs (such as SRB1, SRB2, and SRB 3), thereby implementing fast configuration of the link between L2 and L3 of the terminal.

An embodiment of the present application provides an information transmission method, applied to a terminal, as shown in fig. 1, where the method includes:

step 101: sending a random access request to a network side;

step 102: and receiving a random access response (the English can be expressed as Random Access Response, and is called RAR for short) sent by the network side, wherein the random access response at least comprises first information, and the first information is used for establishing a channel between L2 and L3 of the terminal.

In practical application, the terminal may also be referred to as UE, and may also be referred to as a user.

In practical application, the L2 may include a MAC layer and an RLC layer, the L3 may include an RRC layer, and specific protocol layers included in the L2 and the L3 may be set according to requirements, that is, other protocol layers belonging to the L2 and the L3 in the mobile communication system are also within the protection scope of the present application, which is not limited in the embodiment of the present application.

In practical application, the channel between L2 and L3 of the terminal may be used to meet QoS requirements of the user, that is, to perform QoS guarantee.

Based on this, in an embodiment, the first information may indicate at least one channel between L2 and L3, one channel corresponding to at least one QoS class, each channel being capable of QoS guarantee based on the corresponding QoS class; in other words, each channel has QoS guarantee capability.

In practice, each channel may correspond to a different QoS class, i.e., to a different QoS guarantee requirement (i.e., qoS requirement).

In practice, the channels may be in the form of bearers (such as data radio bearers (DRBs, data Radio Bearer)), or may be other than bearers, such as by transmissions, to guarantee QoS requirements. Wherein, guaranteeing QoS requirements through transmission means that no bearer is established, such as no DRB in the related art is established.

In practical application, the channel may also be called QoS Oriented Link (QOL), etc., and the name of the channel is not limited in the embodiment of the present application, so long as the function is implemented.

In practical application, at least one channel between L2 and L3 may be indicated by the identification of the channel.

Based on this, in an embodiment, the first information may comprise an identification of at least one channel, such as an ID.

In practical application, in the case that at least two channels between L2 and L3 are indicated by the identification of the channel, the identification of the at least two channels may be continuous or discontinuous.

In practical application, at least one channel between L2 and L3 may also be indicated by the identification of the channel and the number of channels.

Based on this, in an embodiment, the first information may include an identification of at least one channel and third information characterizing the number of channels.

In practical application, in the case that at least two channels between L2 and L3 are indicated by the identification of the channels and the number of the channels, the identification of the at least two channels may be continuous or discontinuous.

In practical application, when the first information indicates at least two channels between L2 and L3 and the identifiers of the at least two channels are continuous, the at least two channels between L2 and L3 may be indicated by the identifier of the first channel and the number of channels.

Based on this, in an embodiment, the first information may contain second information characterizing an identity of a first channel of the at least two channels, the identity of the at least two channels being consecutive, and third information characterizing a number of channels.

Here, the first channel refers to a channel corresponding to a first identifier of the at least two continuous identifiers, that is, a channel with the identifier numbered first. Illustratively, as shown in fig. 2, in the case where L3 includes an RRC layer and L2 includes a MAC layer, assuming that n+1 lanes between the RRC layer and the MAC layer are identified as 0 to n, n is an integer greater than or equal to 1, the first lane refers to lane_0, i.e., the second information may include 0, and the third information may include n+1.

In practical application, the specific mode of carrying the first information by the random access response can be set according to requirements. For example, in the case where L3 includes an RRC layer and L2 includes a MAC layer, the second information and the third information may be added to the random access response PDU shown in fig. 3, to obtain the random access response PDU carrying the first information shown in fig. 4; wherein, the MAC UE ID is expressed as the ID allocated to the terminal, namely, the MAC layer is defined to have the capability of allocating the UE ID; the Basic ID of QOL represents the initial value of the QOL ID configured at the network side, namely the second information; number of QOL indicates the Number of QOL IDs configured at the network side, that is, the third information; in the case where the Basic ID of QOL is 0 and the Number of QOL is 8, the QOL configured on the network side is 0 to 7, that is, the first information indicates 8 channels between the RRC layer and the MAC layer, which are numbered 0 to 7.

In the embodiment of the present application, in step 101, the terminal initiates a random access request according to the requirement, that is, initiates a random access request according to the QoS requirement or class.

Based on this, in an embodiment, the method may further include:

and sending a random access request to a network side according to at least one QoS requirement or grade.

When random access is initiated, the terminal selects a Preamble according to QoS requirements or grades. In an embodiment, the terminal may determine a Preamble according to at least one QoS requirement or class, and send a random access request to the network side using (i.e., using) the determined Preamble.

Here, the random access request includes a determined Preamble, i.e., a Preamble corresponding to the at least one QoS requirement or class.

In actual use, the at least one QoS requirement or level may be at least one QoS requirement or level that may be used by the terminal.

Based on this, in an embodiment, the method may further include:

determining at least one QoS requirement or level that may be used;

the Preamble is determined based on the determined at least one QoS requirement or level of possible use.

In practical application, the terminal may determine the Preamble in a display Mode (english may be expressed as Explicit Mode), that is, the terminal and the network side may associate QoS requirements or levels with the Preamble according to the same understanding. For example, the terminal and the network side may pre-store the association relationship (may be understood as a mapping rule) between QoS requirements, qoS levels, preambles and identities of channels as shown in table 1, where the relationship is indexed by channels (i.e., identities of channels), i.e., each channel may correspond to the same or different preambles, and may correspond to different QoS requirements or levels. The terminal can determine a Preamble corresponding to at least one QoS requirement or grade which is possibly used according to the relation, and send a random access request containing the Preamble to the network side; after the network side receives the random access request, the network side can determine the identifier of at least one channel corresponding to the Preamble according to the relation, and instruct the identifier to the terminal, namely send a random access response carrying the first information to the terminal. In this way, by carrying the first information in the random access response to characterize the QoS parameters or characteristics (english may be expressed as Profile), the size of the random access response PDU, i.e. the overhead of the random access response, can be reduced compared to the way in which the QoS parameters or characteristics are directly carried in the random access response.

TABLE 1

Based on this, in an embodiment, the determining the Preamble according to at least one QoS requirement or class may include:

In practical application, after receiving a random access request including a Preamble corresponding to the at least one QoS requirement or level, the network side may determine the first information according to the Preamble corresponding to the at least one QoS requirement or level. Specifically, the network side may determine the identifier of the channel corresponding to the Preamble corresponding to the at least one QoS requirement or level by using the association relationship between the Preamble and the identifier of the channel, so as to obtain the identifier of at least one channel; and determining the first information according to the identification of the at least one channel.

Here, the specific association manner between the Preamble, the QoS requirement, the QoS class, and the identifier of the channel may be set according to the requirement, for example, table 1, which is not limited in the embodiment of the present application. In addition, it should be noted that, the terminal and the network side need to store the same association relationship, that is, the association relationship between the Preamble and the QoS requirement or level and the association relationship between the Preamble and the identifier of the channel, so as to implement display selection of the Preamble, and further implement implicit reporting of the QoS requirement or level, so that the cost of random access can be reduced.

The terminal may also determine the Preamble in an Implicit Mode (english may be expressed as implebit Mode), that is, the terminal and the network side associate QoS requirements or levels with the Preamble according to respective understandings. That is, the terminal and the network side perform mapping between the Preamble, the QoS requirement, the QoS class and the channel according to respective understandings, the mapping on the terminal side may be coarse-grained, the mapping on the network side may be fine-grained, and a specific mapping manner may be set according to requirements, which is not limited in the embodiment of the present application. For example, the terminal may select a suitable Preamble according to its Capability (english may be expressed as UE Capability) and send the Preamble to the network side, where the network side may configure a channel between L2 and L3 for the terminal according to the Preamble by using a preset rule (for example, table 1), that is, send a random access response carrying the first information to the terminal, thereby implementing display selection of the Preamble, and further implementing implicit reporting of QoS requirements or classes, so that the cost of random access can be reduced.

In practical application, the terminal may also perform explicit reporting of QoS requirements or levels, that is, the random access request may include at least one QoS requirement or level, each QoS level may include a plurality of QoS requirements, and each QoS requirement may include a plurality of QoS parameters or features, that is, the random access request directly carries at least one QoS requirement or level.

In an embodiment, the method may further comprise:

Specifically, in practical application, after receiving the random access response carrying the first information, the terminal may establish at least one channel between L2 and L3 according to the first information, that is, activate at least one channel between L2 and L3, that is, the first information is used to activate a channel between L2 and L3 of the terminal, which may also be referred to as the first information is used to enable a channel between L2 and L3 of the terminal. It can be understood that the same channel as the terminal side is also established between L2 and L3 of the network side, and when L2 and L3 interact with each other, L2 and L3 can both select an appropriate channel for data transmission according to the characteristics of the data packet to be sent to L3 or the data packet to be sent to L2.

When the L2 and the L3 send the data packet, the importance of the data packet can be judged by using a preset algorithm, and a proper channel is selected according to the importance of the data packet; for example, the RRC layer needs to send signaling of the basic context of the terminal to the MAC layer, and if the importance priority is higher, a channel with high QoS guarantee capability is selected; the MAC layer needs to send information with lower importance priority to the RRC layer, and may select a lower or general QoS securing capability channel. For another example, after the MAC layer at the network side receives the random access request including the Preamble corresponding to the at least one QoS requirement or class, a channel with high QoS guarantee capability may be used to send a message to the RRC layer; after the terminal accesses the network, for the measurement reported by the terminal, the MAC layer at the network side may select a channel with a lower or general QoS guarantee capability to send to the RRC layer.

In practical application, the network side may pre-establish at least one channel between L2 and L3. Specifically, the network side may establish, for the service type supported by the wireless air interface, a QoS requirement or class of data of each service sent by the air interface, and establish, for each QoS requirement or class, a different channel between L2 and L3. When a channel is established between L2 and L3, the network side may establish at least one channel based on big data (i.e. historical service data) by using a preset Artificial Intelligence (AI) algorithm according to the common QoS guarantee requirement of data transmitted between L2 and L3 by a terminal in the network. In practical application, the network side may pre-establish at least one channel through RRC signaling, or may pre-establish at least one channel through default configuration, which is not limited in the embodiment of the present application. After receiving the random access request sent by the terminal, the network side can determine a channel available to the terminal in the established channels according to the QoS requirement or grade of the terminal, determine the first information according to the determined channel available to the terminal, and send a random access response carrying the first information to the terminal.

Correspondingly, the embodiment of the application also provides an information transmission method applied to the network equipment (specifically, the base station), as shown in fig. 5, the method comprises the following steps:

step 501: receiving a random access request sent by a terminal;

step 502: and sending a random access response to the terminal, wherein the random access response at least comprises first information, and the first information is used for establishing a channel between L2 and L3 of the terminal.

In one embodiment, the random access request includes at least one Preamble corresponding to a QoS requirement or class; the method further comprises the steps of:

In an embodiment, the determining the first information according to the Preamble corresponding to the at least one QoS requirement or class includes:

and determining the first information according to the identification of the at least one channel, wherein the first information indicates at least one channel between L2 and L3, one channel corresponds to at least one QoS grade, and each channel can carry out QoS guarantee based on the corresponding QoS grade.

Here, it should be noted that: the specific processing procedure of the network device is described in detail above, and will not be described in detail here.

Correspondingly, the embodiment of the application also provides an information transmission method, as shown in fig. 6, which comprises the following steps:

step 601: the terminal sends a random access Request (English may be expressed as Msg1: RA Request) to the network side, and then step 602 is executed;

step 602: the network side transmits a random access Response (english may be expressed as New Msg2: RA Response) to the terminal, and then step 603 is performed;

step 603: the terminal sends a random access response acknowledgement message (english may be expressed as ACK for Msg 2) to the network side.

In step 601, the terminal may select an appropriate Preamble according to the QoS guarantee requirement (i.e., qoS requirement or level) of the content to be transmitted; by sending a random access request carrying a Preamble to a network side, at least one QoS requirement or level that may be used by a terminal is indicated to the network side, for example, a plurality of QoS levels are indicated by a Preamble by using an association relationship shown in table 1.

In step 602, after receiving the Preamble, the network side may determine a channel between L2 and L3 of the terminal according to the Preamble, for example, determine at least one channel by using the association relationship shown in table 1; and configuring a channel to the terminal through the random access response, namely sending the random access response carrying the first information to the terminal.

According to the information transmission method provided by the embodiment of the application, the terminal sends the random access request to the network side and receives the random access response sent by the network side, wherein the random access response at least comprises first information, and the first information is used for establishing a channel between L2 and L3 of the terminal. According to the scheme provided by the embodiment of the application, the link information between the L2 and the L3 is carried in the random access response, the network side configures the link between the L2 and the L3 through the random access response, SO that the terminal can establish a channel between the L2 and the L3, such as a channel between an RRC layer and a MAC layer, such as a channel between the RRC layer and the RLC layer, according to the configured information, thereby enabling the terminal to be capable of realizing the quick configuration of the link between the L2 and the L3 of the terminal without establishing SRB (such as SRB1, SRB2 and SRB 3) in the RRC registration process, and further being capable of meeting the data transmission requirement of a user, such as QoS guarantee, by utilizing the channel between the L2 and the L3 when the terminal and the network side interact, SO as to realize SOF of a protocol stack function and further realize SO-RAN.

In addition, according to the scheme provided by the embodiment of the application, random access can be realized rapidly only through two steps, and less information (namely the first information) is added in the random access response, so that the efficiency of accessing the terminal into the network can be improved.

Thirdly, the scheme provided by the embodiment of the application proposes an HARQ mechanism for the random access response (i.e. step 603 shown in fig. 6), so that high-feasibility data transmission can be realized.

Fourth, in the scheme provided by the embodiment of the present application, when L3 includes an RRC layer and L2 includes a MAC layer, by using a channel between the RRC layer and the MAC layer, a function definition of the RRC layer and a definition of "link" or "link" of a conventional Access (AS) layer (i.e., a definition of RRC Connection) can be reconstructed. In other words, the RRC layer can newly define the context of the terminal (english may be expressed as UE context), for example, the RRC layer may allocate an identifier to the terminal (english may be expressed as UE ID) itself, or may use an identifier allocated to the terminal by the MAC layer. In addition, the QoS can be guaranteed through the data transmission between the RRC layer and the MAC layer without establishing the RRC Connection, that is, without establishing the bearer, only with simple activation information (that is, new Msg2 in fig. 6), so that the terminal can implement RRC authentication on the network side in a manner of registering a service.

Fifth, in the solution provided in the embodiment of the present application, when L3 includes an RRC layer and L2 includes an MAC layer, since a channel between the RRC layer and the MAC layer on the network side is fixed, when a terminal moves from one base station to another base station, a handover of an RRC Connection in the related art is not required, so that a "0" handover on the RAN can be implemented.
