In describing embodiments of the present application, some concepts used in the following description are first explained.

1. 6G network protocol stack

AS shown in fig. 1, the protocol stack function of the AS layer of 6G is that, with respect to the 5G protocol stack, the UP function of the new L3 is added to the L3 of the AS layer to process the packet, which is denoted AS L3UP, except for the conventional radio resource control (RRC, CP of L3) function.

The new packet processing function (Packet Processing) of the L2 of the AS layer is designed again, and the new packet processing function of the L2 is mainly characterized by bearing the service data of the upper layer, and combines the channel characteristics of the air interface of the lower layer to form QoS indexes and operations which take the air interface and the service characteristics into consideration.

The UP of L3 of the AS layer has a transmission function of the IP packet for the first time or more. With the introduction of the UP function of L3, the existing data processing function of L2 needs to be redefined.

The introduction of L3 UP brings new mode of AS layer data processing, and can realize seamless and lossless forward transfer of data when the user moves.

The flexible protocol stack of 6G is shown in fig. 2, and includes CP and UP functions in L3, and may include multiple PDCP, RLC, MAC, and SDAP functions in L2. In this scheme, there are various correspondence relationships between different protocol sublayers, and multiple functional bodies may exist in the same functional protocol sublayers at the same time.

In the AS layer, the corresponding relation of the protocol sublayers among the layers is in a many-to-one or one-to-many relation, the functional bodies of the same protocol stack sublayers are not unique, and when the protocol data units (Protocol Data Unit, PDU) are transmitted among the layers, the functional bodies of the source protocol sublayers and the destination protocol sublayers are not unique. Therefore, the transmitting end and the receiving end need to have unified RRC signaling, so that the transmitting end and the receiving end can ensure that the processing of data is consistent.

The embodiment of the invention provides a wireless network protocol stack configuration method, which is used for solving the problem that the consistency of a receiving end and a transmitting end cannot be ensured by the existing wireless network protocol stack configuration method.

As shown in fig. 3, an embodiment of the present invention further provides a method for configuring a wireless network protocol stack, which is applied to a terminal, and includes:

step 301, receiving protocol function configuration information sent by a network side device, where the protocol function configuration information is protocol function configuration information of a target protocol function link protocol function model corresponding to a service requirement of a terminal;

step 302, determining relevant information of protocol function links of the service requirements according to the protocol function configuration information.

routing information between protocol function links;

connection information between protocol function links.

And the terminal determines the information contents such as protocol function links, routing information among the protocol function links, connection information among the protocol function links and the like required by the service requirements according to the protocol function configuration information. The protocol function link may include a wireless link required when executing a service corresponding to the service requirement.

In this embodiment, since a plurality of protocol sub-layer functional units such as PDCP, RLC, SDAP may be included in the L3, a many-to-one or one-to-many correspondence may be included between each of the protocol sub-layer functional units. The network side device determines all protocol function links appearing in the access layer according to the multi-form connection mode appearing between each protocol sub-layer (such as RRC, L3UP, SDAP, PDCP, RLC, MAC and the like) of the access layer in the protocol stack, and configures protocol function configuration information of each protocol function link, for example: the protocol function links include protocol sub-layer functions, functions of the respective protocol sub-layer functions, connection relations between the protocol sub-layer functions, and the like.

The network side equipment designs functions of each protocol sub-layer and topology among the protocol sub-layers based on the division of each protocol sub-layer aiming at protocol function configuration information determined for each protocol function link, and the protocol function configuration information establishes a protocol function model corresponding to each protocol function link, wherein each protocol function model can respectively correspond to needed protocol related information of different service demands. Each protocol function model is used to implement a different business requirement, respectively. In each protocol function model, the link relationships between the various protocol sub-layer functionalities may be displayed, and the protocol sub-layer functionalities experienced by each corresponding link are deterministic and known.

When the terminal has service requirements, the service requirements can be sent to the network side equipment, the network side equipment matches corresponding target protocol function models according to the service requirements of the terminal and sends protocol function configuration information corresponding to the target protocol function models to the terminal, and the terminal establishes protocol function links when the service corresponding to the service requirements is realized according to the protocol function configuration information, so that the consistency of network protocol stacks of the terminal and the network side equipment is realized.

For example, the target protocol function model may indicate a link relationship between protocol sub-layer functional bodies included in the protocol function link, and the terminal may establish the protocol function link of the service requirement according to the protocol function configuration information corresponding to the target protocol function model.

According to the embodiment of the invention, the terminal receives the protocol function configuration information aiming at the service requirement of the terminal and sent by the network side equipment, and determines the relevant information of the protocol function link required by the service requirement according to the protocol function configuration information, so that the consistency of network protocol stacks of the terminal and the network side equipment is ensured, and the end-to-end protocol function link control with low cost is realized.

protocol functions required by the service requirements;

connection relation between protocol sub-layer functional bodies;

routing relationships between protocol sublayer functionalities;

a wireless link;

protocol sublayer functionality comprised by the wireless link;

a radio bearer comprised by the radio link;

a logical channel comprised by the wireless link;

the wireless link includes a transmission channel.

It should be noted that each protocol function model established by the network side device may correspond to different service requirements, and each protocol function model is used for indicating the at least one item of information of the corresponding service requirement.

Optionally, the method further comprises:

the receiving the protocol function configuration information sent by the network side device includes: and receiving an RRC signaling sent by the network side equipment, wherein the RRC signaling carries the protocol function configuration information.

In this embodiment, the terminal initiates RRC connection, and may send a first request message in RRC-related signaling, where the first request message is used to indicate a service requirement of the terminal. And the network side equipment determines a target protocol function model corresponding to the service requirement from a plurality of protocol function models according to the service requirement of the terminal, and determines protocol function configuration information corresponding to the target protocol function model. And the network side equipment sends the protocol function configuration information to the terminal through RRC signaling. The network side device may carry the protocol function configuration information in the following RRC signaling process:

RRC connection setup (RRC connection establishment) message, for example: RRC Setup request (RRC Setup Request), RRC Setup (RRC Setup), RRC Setup complete (RRC Setup Complete), etc.;

RRC reconfiguration (RRC reconfiguration) message, for example: RRC reconfiguration complete (RRC Reconfiguration Complete) message.

(1) Protocol function link identification. For example: RL ID; all RLs are collectively numbered with the link configuration when connecting MACs, for example, 0 to n shown in fig. 4, and are labeled as links ID (Radio Link ID), in the embodiment of the present application, each link as shown in fig. 4 corresponds to a different protocol function, so each link is called a protocol function link, and in each protocol function link, a plurality of protocol sub-layer functional units may be included, where the protocol sub-layers include, for example: l1, L2, L3, the functionality contained in each protocol sub-layer is referred to as a protocol sub-layer functionality. For example: the protocol function link numbered 0 includes: RLC, PDCP, RRC, etc.

(2) The protocol function link is the indication information of the bidirectional bearing; i.e. the protocol function link can be used for information transmission or information reception.

(3) The type of protocol function link; the indication protocol function link is a signaling link or a data link and may be defined according to the function of the protocol sub-layer function (i.e. the first function) of the originating node.

(4) Protocol function links include protocol sub-layer functions; i.e., the protocol sub-layer functionality that the RL needs to go through.

(5) The protocol function links the functions of the protocol sub-layer functional body; i.e. the functionality that the RL needs to experience with the protocol sub-layer functionality.

(6) The protocol function links the identification information in the protocol sub-layer function; for example, the RL corresponds to a local ID inside the protocol sublayer functionality.

(7) The protocol function links the mapping information in the protocol sub-layer function; indicating how the RL maps with lower layer protocol sub-layer functionality.

(8) The protocol function links the aggregation requirement information in the protocol sub-layer function body; indicating with which RL the RL needs to be aggregated. Since multiple RL's can be built within one protocol sub-layer functionality, it can also be built within different multiple RL protocol sub-layer functionalities. That is, as with conventional multiple DRBs built into one PDCP protocol function, multiple RLs may also be built into one protocol sub-layer function, thus configuring the aggregate requirements of the RLs with other RLs.

(9) The protocol function link contains an identification of the protocol sub-layer function, i.e., identification information of each protocol sub-layer function experienced by the RL, such as a function ID. The function IDs may be uniformly numbered under uniform control of the RRC. Such as L3UP in fig. 4, may be configured with IDs of 0 and 1, respectively.

(10) The protocol function links the quality of service QoS requirements when transmitting information. QoS guarantee requirements (QoS parameters) when the RL transmits information (uplink or downlink); for example: when each protocol sub-layer functional body is experienced, the protocol sub-layer functional body needs to give the service quality requirement reached when the information packet is sent.

(11) The MAC function in the protocol function link processes the function configuration parameters of the data packet. For example: the guaranteed modulation and coding scheme (Modulation and coding scheme, MCS) minimum or maximum, the maximum number of hybrid automatic repeat request (Hybrid automatic repeat request, HARQ) retransmissions, whether a HARQ parallel process can be started for multiplexed parallel transmission of protocol data units (Protocol Data Unit, PDUs), the maximum or maximum transmit power, the priority at which RL is scheduled, the mode of the HARQ or HARQ process (asynchronous mode or synchronous mode), the timing mode of the uplink feedback, the physical channel or physical time domain or frequency domain resources of the uplink feedback, etc.

(12) The protocol function links the associated configuration parameters of the contained protocol sub-layer functionalities.

This embodiment is divided into a signaling link and a data link according to the function of the initiation protocol sublayer, and the link connected to RRC is called a signaling link, and the link connected to the functional body such as L3UP, SDAP, PDCP, RLC is called a data link. Each link ends with a connection MAC and is numbered uniformly based on the MAC. As shown in fig. 4, from 0 to n, the reference numerals are link IDs, that is: RL ID.

As shown in fig. 4, among the 0 to n protocol function links, links 0, 1, 2, 3 are signaling links because they are connected with RRC (i.e., the starting node is RRC);

wherein link id=0: the MAC reaches RRC through the RLC functional body 0 and the PDCP functional body 0;

link id=1: the MAC reaches RRC through the RLC functional body 1 and the PDCP functional body 1;

link id=2: the MAC reaches RRC through the RLC functional body 2 and the PDCP functional body 1;

link id=3: the MAC directly connects RRC.

For links 1 and 2, a dual link of PDCP and RLC is employed; for link 3, mac and RRC are directly connected.

Of the 0 to n links, links 4 to n are data links because of the connection of L3UP or SDAP, wherein:

link id=4: MAC is directly connected with the L3UP functional body 0;

link id=n: MAC is directly connected with SDAP function body 1;

In this embodiment, each protocol functional link comprises two layers, a radio network layer (Radio Network Layer, RNL) and a transport network layer (Transport Network Layer, TNL). The RNL identifies the sub-layer Node (Sublayer Node) that the link experiences and the TNL layer identifies the transport function between two adjacent sub-layer nodes.

(1) Protocol function link identification. For example: RL ID; all RLs are collectively numbered in the link configuration when connecting MACs, for example 0 to n as shown in fig. 4.

(11) The MAC function in the protocol function link processes the function configuration parameters of the data packet. For example: the guaranteed minimum or maximum MCS value, the maximum number of HARQ retransmissions, whether the HARQ parallel process can be started to perform multiplexing parallel transmission on the PDU, the maximum or maximum transmission power, the priority when the RL is scheduled, the mode of the HARQ or HARQ process (asynchronous mode or synchronous mode), the timing mode of the uplink feedback, the physical channel or physical time domain or frequency domain resource of the uplink feedback, and the like.

(13) And the transmission configuration information of the transmission network layer TNL corresponding to the two adjacent protocol sub-layer functional bodies in the protocol functional link. The transmission configuration of the corresponding TNL layer between two adjacent protocol sub-layer functional bodies experienced by the RL, for example, adopts IP, SCTP, GTP, even various TNL types such as direct transmission link MAC, etc., qoS guarantee capability of each transmission link, transmission link parameters, etc.

(14) When the protocol function link is a data link, the protocol function link is a mapping relationship of the bearer between the non-access stratum NAS. I.e. if the RL is a data link, the mapping relationship of the link and the corresponding bearer of the NAS layer is configured.

AS an optional embodiment, after the network side device configures the protocol function configuration information of the protocol function link, the protocol function model is established according to the protocol function configuration information, where the protocol function model is shown in fig. 6, and the user plane function entity (User Plane Function, UPF) excluding the NAS layer, the access and mobility management function (Access and Mobility Management Function, AMF) and the like are unified connection models between protocol sublayers of the AS layer L1/L2/L3. In the model shown in fig. 6, with MAC as the termination point, all links terminate to the MAC layer; according to different functions of the initial protocol sub-layer, the signaling link and the data link are divided; the connection to RRC is called signaling link, the connection to L3UP, SDAP, PDCP, RLC, etc. is called data link. In this model, each link is deterministic, known, and explicit from the originating protocol sub-layer functionality to the protocol sub-layer functionality experienced by the MAC layer protocol sub-layer functionality. And each link sets a proper protocol sub-layer function body and transmission guarantee capability according to different carried information. Each link contains two layers, RNL, which identifies the sub-layer Node (Sublayer Node) that the link experiences in fig. 6, and TNL, which identifies the transport function between two adjacent sub-layer nodes in fig. 6.

In the model shown in fig. 6, each link ends with a connection MAC and is numbered uniformly based on the MAC, e.g., 0 to n in fig. 4. The reference number is a link ID, namely: RL ID. Each sub-layer node experienced by each link has the functions of routing, ordering and the like of data packets according to the form of the link connection, such as many-to-one aggregation or multiplexing and one-to-many mapping.

Each link is not unique in its path from the start node to the end node (MAC). As for the two links of rl=5 and rl=i in fig. 4, after many-to-one aggregation or multiplexing (one PDCP for multiple SDAPs) or one-to-many mapping (one PDCP for multiple SDAPs) between RLC, PDCP, SDAP, the data transmitted from the two L3UP functions has been mixed on the links of rl=5 and rl=i, so the description at this time is: each L3UP corresponds to links rl=5 and rl=i.

Compared to the conventional establishment of multiple bearers within the same protocol sublayer, the embodiment of the present application establishes more than one protocol sublayer with the same function at the same time, and routes between the protocol sublayer functionalities, for example: one SDAP protocol sub-layer corresponds to a plurality of independent PDCP protocol sub-layer functional bodies at the same time, and QoS Flow in the SDAP can be mapped to one or a plurality of independent PDCP protocol sub-layers; conversely, one PDCP may correspond to multiple SDAP protocol sublayer functionalities.
