Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a wireless network protocol stack configuration method, apparatus, terminal, and network-side equipment. Background Technology

[0002] To achieve the design goal of a Lite Network for next-generation mobile communications, a User Plane (UP) function is proposed to be introduced in Layer 3 for data processing. This UP function (denoted as L3UP) is introduced in the Access Stratum (AS) layer at L3. In 3G / 4G / 5G systems, the L3 layer at the AS layer only has a Control Plane (CP), i.e., only the RRC protocol layer (or sublayer), with the Radio Resource Control (RRC) protocol layer performing radio resource control functions.

[0003] In 6G, a Service Based Architecture (SBA) Radio Access Network (RAN) scheme was proposed. In the SBA RAN scheme, a UE can simultaneously have multiple L3UP / Service Data Adaptation Protocol (SDAP) / Packet Data Convergence Protocol (PDCP) / Radio Link Control (RLC) protocol functionalities. That is, the correspondence between protocol sublayers becomes many-to-one or one-to-many, and the functionalities of the same protocol stack sublayer are not unique.

However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0321] In describing the embodiments of this application, some concepts used in the following description will first be explained.

[0322] I. 6G Network Protocol Stack

[0323] The protocol stack functions of the 6G AS layer are as follows: Figure 1 As shown, compared to the 5G protocol stack, for the L3 layer of the AS layer, in addition to the traditional radio resource control (RRC, L3 CP) functions, a new L3 UP function is added to process data packets, denoted as L3UP.

[0324] The L2 packet processing function of the AS layer has been redesigned. The new L2 packet processing function mainly takes into account the characteristics of the upper layer service data and combines the channel characteristics of the lower layer air interface to form QoS indicators and operations that take into account both air interface and service characteristics.

[0325] The L3 UP function in the AS layer has the ability to send IP packets once or more. With the introduction of the L3 UP function, the existing data processing functions of L2 need to be redefined.

[0326] The introduction of L3 UP brings a new way of data processing in the AS layer, enabling seamless and lossless forward transfer of data when the user moves.

[0327] 6G flexible protocol stack such as Figure 2As shown, L3 includes CP and UP functional units, while L2 can include multiple PDCP, RLC, MAC, and SDAP functional units. In this scheme, there are various correspondences between different protocol sublayers, and multiple functional units of the same protocol sublayer can coexist simultaneously.

[0328] At the AS layer, the correspondence between protocol sublayers exhibits many-to-one or one-to-many relationships, and the functional body of the same protocol stack sublayer is not unique. When transmitting Protocol Data Units (PDUs) between layers, the functional bodies of the source and destination protocol sublayers are not unique. Therefore, the sending and receiving ends need to have unified RRC signaling to ensure that the sending and receiving ends process data in a consistent manner.

[0329] This invention provides a wireless network protocol stack configuration method to solve the problem that existing wireless network protocol stack configuration methods cannot guarantee the consistency between the receiving end and the sending end.

[0330] like Figure 3 As shown, this embodiment of the invention also provides a wireless network protocol stack configuration method, applied to a terminal, including:

[0331] Step 301: Receive protocol function configuration information sent by the network-side device. The protocol function configuration information is the protocol function configuration information of the target protocol function link protocol function model corresponding to the service requirements of the terminal.

[0332] Step 302: Determine the relevant information of the protocol function link for the business requirement based on the protocol function configuration information.

[0333] Optionally, the relevant information of the protocol function link includes at least one of the following:

[0334] Routing information between protocol function links;

[0335] Connection information between protocol function links.

[0336] The terminal determines, based on the protocol function configuration information, the protocol function links required for the service requirement, the routing information between protocol function links, and the connection information between protocol function links. The protocol function links may include the wireless links required to execute the service corresponding to the service requirement.

[0337] In this embodiment, since L3 may include multiple protocol sublayer functional units such as PDCP, RLC, and SDAP, there may be many-to-one or one-to-many correspondences between these sublayer functional units. The network-side device, considering the various connection methods between different protocol sublayers (such as RRC, L3UP, SDAP, PDCP, RLC, MAC, etc.) in the access layer of the protocol stack, determines all protocol function links appearing in the access layer and configures the protocol function configuration information for each link, such as: the protocol sublayer functional units included in the link, the functions of each sublayer functional unit, and the connection relationships between them.

[0338] Network-side devices, based on the protocol function configuration information determined for each protocol function link, design the functions of each protocol sublayer and the topology between them, according to the division of each protocol sublayer. The protocol function configuration information establishes a protocol function model corresponding to each protocol function link. Each protocol function model can correspond to the protocol-related information required for different business needs. Each protocol function model is used to implement different business needs. Within each protocol function model, the link relationships between the functional bodies of each protocol sublayer can be displayed, and the functional bodies of the protocol sublayers traversed by each link are determined and known.

[0339] When a terminal has a service requirement, it can send the service requirement to the network-side device. The network-side device matches the corresponding target protocol function model according to the terminal's service requirement and sends the protocol function configuration information corresponding to the target protocol function model to the terminal. The terminal establishes a protocol function link to implement the service corresponding to the service requirement according to the protocol function configuration information, thereby achieving consistency between the network protocol stack of the terminal and the network-side device.

[0340] For example, the target protocol function model can indicate the linking relationship between the protocol sublayer functions contained in the protocol function link, and the terminal can establish the protocol function link of the service requirement according to the protocol function configuration information corresponding to the target protocol function model.

[0341] In an embodiment of the present invention, the terminal receives protocol function configuration information for the service requirements of the terminal sent by the network-side device, determines the relevant information of the protocol function links required for the service requirements based on the protocol function configuration information, ensures the consistency of the network protocol stacks of the terminal and the network-side device, and realizes low-overhead end-to-end protocol function link control.

[0342] Optionally, the target protocol function model indicates at least one of the following:

[0343] The protocol functions required by the business requirements;

[0344] The protocol sublayer functional body required to be established for the aforementioned business requirements;

[0345] The protocol sublayer functionalities that need to be modified according to the business requirements;

[0346] The protocol sublayer functionalities that need to be deleted according to the business requirements;

[0347] The connection relationships between protocol sublayer functional units;

[0348] Routing relationships between protocol sublayer functionalities;

[0349] Wireless link;

[0350] The protocol sublayer functionalities included in a wireless link;

[0351] The connection relationships between protocol sublayer functional units contained in a wireless link;

[0352] The wireless bearer included in a wireless link;

[0353] The logical channels included in a wireless link;

[0354] The transmission channels included in a wireless link.

[0355] It should be noted that each protocol function model established by the network-side device can correspond to different service requirements, and each protocol function model is used to indicate at least one of the above-mentioned information of its corresponding service requirements.

[0356] Optionally, the method further includes:

[0357] Send a first request message to the network-side device, wherein the first request message indicates the service requirements of the terminal;

[0358] The receipt of protocol function configuration information sent by the network-side device includes: receiving RRC signaling sent by the network-side device, wherein the RRC signaling carries the protocol function configuration information.

[0359] In this embodiment, when a terminal initiates an RRC connection, it can send a first request message in the RRC-related signaling. This first request message indicates the terminal's service requirements. Based on the terminal's service requirements, the network-side device determines the target protocol function model corresponding to the service requirements from multiple protocol function models, and determines the protocol function configuration information corresponding to the target protocol function model. The network-side device sends the protocol function configuration information to the terminal via RRC signaling. The network-side device can carry the protocol function configuration information in the following RRC signaling processes:

[0360] RRC connection establishment messages, such as RRC Setup Request, RRC Setup, and RRC Setup Complete.

[0361] RRC reconfiguration messages, such as the RRC Reconfiguration Complete message.

[0362] Optionally, the protocol function configuration information includes at least one of the following:

[0363] (1) Protocol Function Link Identifier. For example: RL ID; all RLs are uniformly numbered according to the link configuration when connecting to the MAC, for example... Figure 4 The numbers 0 to n shown are labeled as Radio Link IDs. In the embodiments of this application, such as... Figure 4 Each link in the protocol chain corresponds to a different protocol function; therefore, each link is called a protocol function link. Each protocol function link can include multiple protocol sub-layer functional bodies, such as L1, L2, and L3. The functional bodies contained within each protocol sub-layer are called protocol sub-layer functional bodies. For example, protocol function link number 0 includes protocol sub-layer functional bodies such as RLC, PDCP, and RRC.

[0364] (2) The protocol function link is a bidirectional carrier of indication information; that is, the protocol function link can send information or receive information.

[0365] (3) Type of protocol function link; indicates whether the protocol function link is a signaling link or a data link, which can be defined according to the function of the protocol sublayer function body (i.e. the first function body) of the starting node.

[0366] (4) Protocol sublayer functional bodies included in the protocol functional link; that is, the protocol sublayer functional bodies that the RL needs to go through.

[0367] (5) The functions of the protocol sublayer functions included in the protocol function link; that is, the functions of the protocol sublayer functions that the RL needs to go through.

[0368] (6) Identification information of protocol function links in protocol sublayer function bodies; for example, RL corresponds to a local ID inside the protocol sublayer function body.

[0369] (7) Mapping information of protocol function links in protocol sublayer function bodies; indicating how RL is mapped to lower-level protocol sublayer function bodies.

[0370] (8) Aggregation requirement information of protocol function links in protocol sublayer function bodies; indicating which RLs need to be aggregated with. Since multiple RLs can be established within one protocol sublayer function body, or within different multiple RL protocol sublayer function bodies. That is, just like multiple DRBs are established within one PDCP protocol function body in the traditional way, multiple RLs can also be established within one protocol sublayer function body, so the aggregation requirements of RLs with other RLs can be configured.

[0371] (9) Identifiers of the protocol sublayer functional bodies included in the protocol functional link, i.e., the identification information of each protocol sublayer functional body traversed by the RL, such as the functional body ID. Functional body IDs can be uniformly numbered under the unified control of the RRC. For example... Figure 4 The L3UP in the configuration can be configured with IDs of 0 and 1.

[0372] (10) Quality of Service (QoS) requirements when transmitting information via protocol function links. QoS guarantee requirements (QoS parameters) when transmitting information (uplink or downlink); for example: when passing through each protocol sublayer function, the protocol sublayer function needs to provide the QoS requirements achieved when sending the information packet.

[0373] (11) Configuration parameters for the MAC function body in the protocol function link to process data packets. For example: the minimum or maximum guaranteed modulation and coding scheme (MCS) value, the maximum number of Hybrid Automatic Repeat Request (HARQ) retransmissions, whether HARQ parallel processes can be started to transmit Protocol Data Units (PDUs) in multiple parallel paths, the maximum or maximum transmit power, the priority when scheduling RL, the mode of HARQ or HARQ process (asynchronous mode or synchronous mode), the timing mode of uplink feedback, the physical channel or physical time domain or frequency domain resources of uplink feedback, etc.

[0374] (12) Configuration parameters of the protocol sublayer functions included in the protocol function link. For example: the function configuration, routing parameters, sorting parameters, RL aggregation, multiplexing or mapping configurations of other protocol sublayer functions traversed by the RL except for the MAC node.

[0375] (13) Transmission configuration information of the Transport Network Layer (TNL) between two adjacent protocol sublayer functional bodies in the protocol function link. The transmission configuration of the TNL layer between two adjacent protocol sublayer functional bodies traversed by the RL, such as the configuration of various TNL types such as IP, Stream Control Transmission Protocol (SCTP), General Packet Radio Service Tunneling Protocol (GTP), or even direct transmission link MAC, the QoS guarantee capability of each transmission link, transmission link parameters, etc.

[0376] (14) When the protocol function link is a data link, the mapping relationship between the protocol function link and the bearer of the non-access stratum NAS. That is, if the RL is a data link, configure the mapping relationship between the link and the corresponding bearer of the NAS layer.

[0377] Optionally, determining the relevant information of the protocol function links required by the business requirement based on the protocol function configuration information includes:

[0378] Based on the protocol function configuration information, establish protocol sublayer function bodies and links between two adjacent protocol sublayer function bodies, and obtain relevant information about the protocol function links.

[0379] In this embodiment, after receiving the protocol function configuration information, the terminal can determine the protocol sub-layer function body in the protocol function link that implements the service requirement, the connection relationship between the protocol sub-layer function bodies, etc., based on the protocol function configuration information, thereby establishing the protocol sub-layer function body of the UE, obtaining the protocol function link, and obtaining the relevant information of the protocol function link.

[0380] As an optional embodiment, the method further includes:

[0381] Based on the processing requirements of the protocol function link, a second request message is sent to the network-side device;

[0382] Receive RRC signaling sent by network-side devices, wherein the RRC signaling carries updated protocol function configuration information;

[0383] The processing requirement is executed based on the updated protocol function configuration information;

[0384] The processing requirements include at least one of the following: establishing new protocol function links, modifying the protocol function links corresponding to the target protocol function model, and deleting the protocol function links corresponding to the target protocol function model.

[0385] In this embodiment, when the UE has processing needs during the RRC process, such as establishing, modifying, or deleting an RL, the UE sends a second request message to the network-side device, indicating the processing needs. The network-side device updates the protocol function configuration information according to the processing needs. For example, when the UE needs to establish a new connection, the network-side device determines the ID of the newly established function body and the functions to be configured based on the various protocol sublayer functions already established in the protocol function link corresponding to the terminal; the network-side device generates the RL scheme for the requested service or other services, configures it on the corresponding protocol sublayer function body, and sends the updated protocol function configuration information to the terminal.

[0386] In an embodiment of the present invention, the terminal receives protocol function configuration information for the service requirements of the terminal sent by the network-side device, determines the relevant information of the protocol function links required for the service requirements based on the protocol function configuration information, ensures the consistency of the network protocol stacks of the terminal and the network-side device, and realizes low-overhead end-to-end protocol function link control.

[0387] like Figure 5 As shown, this application also provides a wireless network protocol stack configuration method, applied to a network-side device, including:

[0388] Step 501: Determine the N protocol function links included in the access layer of the wireless network protocol stack; where N is a positive integer.

[0389] In a wireless network protocol stack, since Layer 3 may include multiple protocol sublayer functionalities such as PDCP, RLC, and SDAP, there may be many-to-one or one-to-many correspondences between these sublayer functionalities. This application's embodiments address the various connection methods that occur between different protocol sublayers (such as RRC, L3UP, SDAP, PDCP, RLC, MAC, etc.) by determining all protocol function links appearing in the access layer.

[0390] Step 502: Configure the protocol function configuration information for each of the aforementioned protocol function links;

[0391] For each protocol function link, the network-side device determines the protocol function configuration information, such as the protocol sublayer functions included in the link, the functions of each sublayer function, and the connection relationships between them. Optionally, each protocol function link is configured with appropriate protocol sublayer functions and transmission guarantee capabilities based on the different information it carries, ensuring that the protocol sublayer functions traversed by each link from the initial protocol sublayer function to the MAC layer protocol sublayer function are definite, known, and explicit.

[0392] Step 503: Based on the protocol function configuration information, establish a protocol function model corresponding to each protocol function link;

[0393] For the protocol function configuration information configured for each protocol function link, based on the division of each protocol sublayer, the functions of each protocol sublayer and the topology between the protocol sublayers are designed, that is, the protocol function model corresponding to each protocol function link is established respectively.

[0394] Optionally, the protocol function model indicates at least one of the following:

[0395] The protocol functions required by the business requirements;

[0396] The protocol sublayer functional body required to be established for the aforementioned business requirements;

[0397] The protocol sublayer functionalities that need to be modified according to the business requirements;

[0398] The protocol sublayer functionalities that need to be deleted according to the business requirements;

[0399] The connection relationships between protocol sublayer functional units;

[0400] Routing relationships between protocol sublayer functionalities;

[0401] Wireless link;

[0402] The protocol sublayer functionalities included in a wireless link;

[0403] The connection relationships between protocol sublayer functional units contained in a wireless link;

[0404] The wireless bearer included in a wireless link;

[0405] The logical channels included in a wireless link;

[0406] The transmission channels included in a wireless link.

[0407] Each protocol function model can correspond to different business requirements, that is, to execute different businesses. In each protocol function model, the link relationship between each protocol sublayer function body is displayed, and the protocol sublayer function bodies that each link passes through are determined and known.

[0408] Step 504: Based on the terminal's business requirements, send the protocol function configuration information corresponding to the target protocol function model in the protocol function model to the terminal.

[0409] When a terminal reports a service requirement to a network-side device, the network-side device selects a target protocol function model (PCM) matching the service requirement from among multiple PCM models and sends the corresponding PCM configuration information to the terminal. Based on the received PCM configuration information, the terminal can obtain information about the protocol function links required to implement the service requirement, including the required protocol function links, the protocol sublayer functions included in the links, the connection relationships between these sublayers, and the functions of each sublayer. The terminal then establishes the PCM links to implement the service requirement based on the PCM configuration information, thus achieving consistency between the network protocol stacks of the terminal and the network-side device.

[0410] In an embodiment of the present invention, the network-side device sets protocol function configuration information for N protocol function links in the access layer and generates corresponding protocol function models; according to the service requirements of the terminal, the protocol function configuration information of the target protocol function model corresponding to the service requirements is sent to the terminal, ensuring the consistency of the network protocol stack between the terminal and the network-side device, and realizing low-overhead end-to-end protocol function link control.

[0411] Optionally, the termination node of each of the aforementioned protocol function links is the Media Access Control (MAC) functional body, meaning that all links terminate at the MAC layer with the MAC as the endpoint. The starting node of each of the aforementioned protocol function links is located in L3, such as RRC or UP.

[0412] As an optional embodiment, the determination of the N protocol function links included in the access layer of the wireless network protocol stack includes:

[0413] Step 1: Number all links connecting to the MAC function body in the access layer.

[0414] Step 2: For each link, traverse from the MAC function body to the first function body of the Layer 3 protocol stack to determine the protocol function link to which each link belongs; wherein, the protocol function link includes: all protocol sub-layer function bodies traversed from the MAC function body to the first function body, and the links between two adjacent protocol sub-layer function bodies.

[0415] In this embodiment, the first functional unit is a functional unit in L3, serving as the starting node for protocol function links. Optionally, the first functional unit includes a Radio Resource Control (RRC) functional unit and a user plane functional unit; wherein there is one RRC functional unit and at least one user plane functional unit. Only one RRC protocol sublayer functional unit is established on both the network and terminal sides; any other protocol sublayer can simultaneously establish multiple protocol sublayer functional units, such as... Figure 4The protocol sublayer functionalities shown are excluding RRC.

[0416] like Figure 4 As shown, all links connecting to the MAC function are assigned a unique number, and then the process is sequentially traversed to the L3 protocol stack sub-layer function positions. All protocol sub-layer functions traversed and the links between these functions are called an end-to-end protocol function link. The ID of this end-to-end protocol function link is the value of the unique number assigned to the link connecting to the MAC function. For example... Figure 4 The identified links from 0 to n that connect to the MAC function body.

[0417] Optionally, the method further includes: determining the type of the protocol function link based on the starting node of the protocol function link; wherein the type of the protocol function link includes: signaling link or data link. In this embodiment, the starting node of the protocol function link is the first functional body, that is, the protocol sublayer functional body located in L3, such as: RRC, UP. The type (i.e., nature) of the protocol function link is determined according to the starting node of each protocol function link. In this embodiment, based on the different starting protocol sublayer functions, it is divided into signaling links and data links. The link connected to RRC is called a signaling link, and the link connected to functional bodies such as L3UP, SDAP, PDCP, RLC, etc. is called a data link. Each link ends with a connection MAC address and is uniformly labeled based on the MAC address. Figure 4 In the range 0 to n, the labels are the link IDs, which are: RL IDs.

[0418] like Figure 4 As shown, among the protocol function links 0 to n, links 0, 1, 2, and 3 are signaling links because they are connected to RRC (i.e., the starting node is RRC).

[0419] Where link ID=0: MAC reaches RRC through RLC function body 0 and PDCP function body 0;

[0420] Link ID=1: The MAC reaches the RRC via RLC function body 1 and PDCP function body 1;

[0421] Link ID=2: MAC reaches RRC via RLC function body 2 and PDCP function body 1;

[0422] Link ID=3: MAC directly connects to RRC.

[0423] For Link 1 and Link 2, a dual link using PDCP and RLC is employed; for Link 3, a direct link using MAC and RRC is used.

[0424] Of the 0 to n links, links 4 to n are data links because they connect to L3UP or SDAP.

[0425] Link ID=4: MAC directly connects to L3UP function body 0;

[0426] Link ID = n: MAC directly connects to SDAP function body 1;

[0427] Other links can determine the protocol function link type in the same way as described above, and can determine the function body that each protocol function link goes through, which will not be listed here.

[0428] Optionally, configuring the protocol function configuration information for each of the protocol function links includes: configuring the radio network layer parameters and transport network layer parameters for each of the protocol function links; wherein, the radio network layer parameters are used to indicate the protocol sublayer functions included in the protocol function link; and the transport network layer parameters are used to indicate the transmission functions between two adjacent protocol sublayer functions.

[0429] In this embodiment, each protocol function link comprises two layers: the Radio Network Layer (RNL) and the Transport Network Layer (TNL). The RNL identifies the sublayer nodes traversed by the link, while the TNL layer identifies the transmission functions between two adjacent sublayer nodes.

[0430] Optionally, the protocol function configuration information includes at least one of the following:

[0431] (1) Protocol Function Link Identifier. For example: RL ID; all RLs are uniformly numbered according to the link configuration when connecting to the MAC, for example... Figure 4 The range 0 to n is shown.

[0432] (2) The protocol function link is a bidirectional carrier of indication information; that is, the protocol function link can send information or receive information.

[0433] (3) Type of protocol function link; indicates whether the protocol function link is a signaling link or a data link, which can be defined according to the function of the protocol sublayer function body (i.e. the first function body) of the starting node.

[0434] (4) Protocol sublayer functional bodies included in the protocol functional link; that is, the protocol sublayer functional bodies that the RL needs to go through.

[0435] (5) The functions of the protocol sublayer functions included in the protocol function link; that is, the functions of the protocol sublayer functions that the RL needs to go through.

[0436] (6) Identification information of protocol function links in protocol sublayer function bodies; for example, RL corresponds to a local ID inside the protocol sublayer function body.

[0437] (7) Mapping information of protocol function links in protocol sublayer function bodies; indicating how RL is mapped to lower-level protocol sublayer function bodies.

[0438] (8) Aggregation requirement information of protocol function links in protocol sublayer function bodies; indicating which RLs need to be aggregated with. Since multiple RLs can be established within one protocol sublayer function body, or within different multiple RL protocol sublayer function bodies. That is, just like multiple DRBs are established within one PDCP protocol function body in the traditional way, multiple RLs can also be established within one protocol sublayer function body, so the aggregation requirements of RLs with other RLs can be configured.

[0439] (9) Identifiers of the protocol sublayer functional bodies included in the protocol functional link, i.e., the identification information of each protocol sublayer functional body traversed by the RL, such as the functional body ID. Functional body IDs can be uniformly numbered under the unified control of the RRC. For example... Figure 6 The L3UP in the configuration can be configured with IDs of 0 and 1.

[0440] (10) Quality of Service (QoS) requirements when transmitting information via protocol function links. QoS guarantee requirements (QoS parameters) when transmitting information (uplink or downlink); for example: when passing through each protocol sublayer function, the protocol sublayer function needs to provide the QoS requirements achieved when sending the information packet.

[0441] (11) Configuration parameters for the MAC function body in the protocol function link to process data packets. For example: the guaranteed minimum or maximum value of MCS, the maximum number of HARQ retransmissions, whether HARQ parallel process can be started to send PDUs in multiple parallel paths, the maximum or maximum transmission power, the priority when scheduling RL, the mode of HARQ or HARQ process (asynchronous mode or synchronous mode), the timing mode of uplink feedback, the physical channel or physical time domain or frequency domain resources of uplink feedback, etc.

[0442] (12) Configuration parameters of the protocol sublayer functions included in the protocol function link. For example: the function configuration, routing parameters, sorting parameters, RL aggregation, multiplexing or mapping configurations of other protocol sublayer functions traversed by the RL except for the MAC node.

[0443] (13) Transmission configuration information of the Transport Network Layer (TNL) between two adjacent protocol sublayer functional bodies in the protocol function link. The transmission configuration of the TNL layer between two adjacent protocol sublayer functional bodies traversed by the RL, such as the configuration of various TNL types such as IP, SCTP, GTP, or even direct transmission link MAC, the QoS guarantee capability of each transmission link, transmission link parameters, etc.

[0444] (14) When the protocol function link is a data link, the mapping relationship between the protocol function link and the bearer of the non-access stratum NAS. That is, if the RL is a data link, configure the mapping relationship between the link and the corresponding bearer of the NAS layer.

[0445] As an optional embodiment, after configuring the protocol function configuration information of the protocol function link, the network-side device establishes the protocol function model based on the protocol function configuration information, and the protocol function model is as follows: Figure 6 As shown, excluding the User Plane Function (UPF) and Access and Mobility Management Function (AMF) of the NAS layer, this represents a unified connection model between the protocol sublayers of the AS layer (L1 / L2 / L3). Figure 6 In the model shown, MAC is the endpoint, and all links terminate at the MAC layer. Based on the different functions of the initial protocol sublayer, links are divided into signaling links and data links. Links connected to RRC are called signaling links, while those connected to L3UP, SDAP, PDCP, RLC, etc., are called data links. In this model, the protocol sublayer functions traversed by each link from the initial protocol sublayer function to the MAC layer protocol sublayer function are determined, known, and explicit. Each link is configured with appropriate protocol sublayer functions and transmission guarantee capabilities based on the information it carries. Each link contains two layers: RNL and TNL. RNL identifies... Figure 6 The sublayer nodes traversed by this link are identified by the TNL layer. Figure 6 Transmission function between two adjacent sub-layer nodes.

[0446] Figure 4 In the model shown, each link terminates at the MAC address and is assigned a unified label based on the MAC address, such as... Figure 4 The range is 0 to n. The label is the link ID, also known as the RL ID. Each sub-layer node traversed by each link has functions such as routing and sorting of data packets according to the link connection pattern, such as many-to-one aggregation or multiplexing, and one-to-many mapping.

[0447] Each link has a non-unique path from the start node to the end node (MAC). For example... Figure 6 The two links RL=5 and RL=i in the L3UP have been aggregated or multiplexed (multiple SDAPs correspond to one PDCP) or mapped (one SDAP corresponds to multiple PDCPs) between RLC, PDCP, and SDAP. The data transmitted from the two L3UP functional units has been mixed on the links RL=5 and RL=i. Therefore, the description at this time is: each L3UP corresponds to links RL=5 and RL=i.

[0448] In this embodiment, the network-side device establishes a corresponding protocol function model for each protocol function link. Each protocol function model corresponds to different protocol function configuration information to implement different service transmissions. After receiving the service request sent by the terminal, the device determines the corresponding target protocol function model based on the service request, and then configures the protocol function configuration information corresponding to the target protocol function model to the terminal.

[0449] It should be noted that, Figure 7 The model shown is only an example of a protocol function model. The sub-layer nodes can be set according to the protocol sub-layer function bodies linked by the protocol function, and the connection relationship between each sub-layer node can be set according to the connection relationship between the protocol sub-layer function bodies linked by the protocol function.

[0450] Compared with the traditional approach of establishing multiple bearers within the same protocol sublayer, this embodiment establishes more than one protocol sublayer with the same function simultaneously. Routing between these protocol sublayer functions is as follows: for example, one SDAP protocol sublayer corresponds to multiple independent PDCP protocol sublayer functions, and the QoS Flow in the SDAP can be mapped to one or more independent PDCP protocol sublayers; conversely, one PDCP can correspond to multiple SDAP protocol sublayer functions.

[0451] As an optional embodiment, the step of sending protocol function configuration information corresponding to the target protocol function model in the protocol function model to the terminal according to the terminal's service requirements includes:

[0452] Obtain a first request message sent by the terminal, wherein the first request message indicates the service requirements of the terminal;

[0453] Determine the target protocol function model corresponding to the business requirements from the protocol function model;

[0454] The protocol function configuration information corresponding to the target protocol function model is sent to the terminal via RRC signaling.

[0455] In this embodiment, when a terminal initiates an RRC connection, it can send a first request message in the RRC-related signaling. This first request message indicates the terminal's service requirements. Based on the terminal's service requirements, the network-side device determines the target protocol function model corresponding to the service requirements from multiple protocol function models, and determines the protocol function configuration information corresponding to the target protocol function model. The network-side device sends the protocol function configuration information to the terminal via RRC signaling. The network-side device can carry the protocol function configuration information in the following RRC signaling processes:

[0456] RRC connection establishment messages, such as: RRC setup request, RRC setup, RRC setup complete, etc.

[0457] RRC reconfiguration messages, such as: RRC reconfiguration complete message.

[0458] After receiving the protocol function configuration information, the terminal can determine the protocol sublayer function body and the connection relationship between the function bodies in the protocol function link required by the service requirements, thereby establishing the protocol sublayer function body of the UE and obtaining the protocol function link.

[0459] As an optional embodiment, the method further includes:

[0460] Obtain a second request message sent by the terminal, the second request message indicating the terminal's processing requirement for the protocol function link;

[0461] Based on the processing requirements, configure the protocol function links to obtain updated protocol function configuration information;

[0462] The updated protocol function configuration information is sent to the terminal via RRC signaling;

[0463] The processing requirements include at least one of the following: establishing new protocol function links, modifying the protocol function links corresponding to the target protocol function model, and deleting the protocol function links corresponding to the target protocol function model.

[0464] In this embodiment, when the UE has processing needs during the RRC process, such as establishing, modifying, or deleting a Link Requirement (RL), the UE sends a second request message to the network-side device, indicating the processing needs. The network-side device updates the protocol function configuration information according to the processing needs. For example, when the UE needs to establish a new link, the network-side device determines the ID of the newly established function body and the functions to be configured based on the various protocol sublayer functions already established in the protocol function link corresponding to the terminal. The network-side device generates the RL scheme for the requested service or other services, configures it on the corresponding protocol sublayer function body, and sends the updated protocol function configuration information to the terminal.

[0465] Optionally, the network-side device generates a TNL scheme for the updated RL and configures it on the transport network function between the corresponding protocol sublayer function bodies.

[0466] In the embodiments of this application, the protocol function links between the terminal and the network-side equipment are configured through RRC signaling. The relationship between protocol sublayer functional bodies is one-to-many or many-to-many, no longer the many-to-one relationship between lower layers and higher layers in 5G. This overcomes the limitation of inflexible layer selection in the 5G protocol stack, achieving flexible scaling of protocol stack functions; ensuring protocol stack consistency between the network-side equipment and the terminal; and enabling flexible on-demand connections between different protocol sublayers by configuring the RRC signaling content, protocol sublayer functions, TNL functions, QoS guarantees, etc., for each RL. This allows a UE to simultaneously establish different protocol sublayer functional bodies with the same protocol function, laying the foundation for a protocol stack scheme for SBA RAN, the definition of radio slicing (through this protocol stack scheme, different slices serving the same UE can have the same or different protocol stack functions), and the customization of AS layer protocol stack functions according to different service requirements in 6G.

[0467] In an embodiment of the present invention, the network-side device sets protocol function configuration information for N protocol function links in the access layer and generates corresponding protocol function models; according to the service requirements of the terminal, the protocol function configuration information of the target protocol function model corresponding to the service requirements is sent to the terminal, ensuring the consistency of the network protocol stack between the terminal and the network-side device, and realizing low-overhead end-to-end protocol function link control.
