Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus and storage medium for transmitting endogenous services. Background Technology

[0002] Existing services in 3GPP (3rd Generation Partnership Project) wireless communication networks are end-to-end services, with service establishment initiated and completed between the terminal and the core network via NAS signaling. With the introduction of artificial intelligence, machine learning modules are embedded in various nodes of the wireless mobile communication network, including base stations and terminals. Correspondingly, base stations and terminals possess functions such as model signaling, data processing, and edge computing. Services generated by the application of artificial intelligence in wireless communication networks are a typical example of endogenous services. The characteristics of endogenous services are: both the starting and ending points of the service are within the system, and they do not directly provide services to end users, but are built to solve complex problems in mobile communication systems or improve performance.

[0003] Inherent services, characterized by large data flows during data processing and machine learning model transmission, cannot be transmitted as physical layer signaling and must be transmitted as a separate service flow via data bearers. Furthermore, different types of machine learning have varying requirements regarding latency and reliability; for example, inference processes have high latency requirements, while the transmission of inference results and models requires high reliability. Current transmission technologies cannot meet the transmission needs of inherent services and cannot guarantee reliable transmission of inherent service data or signaling. Summary of the Invention

[0114] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0115] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0116] The services in existing 3GPP wireless communication networks are end-to-end services. The service establishment process is initiated and completed between the terminal and the core network via NAS signaling. The service establishment process initiated by the terminal is as follows: If the terminal is in RRC (Radio Resource Control) connection state, it directly interacts with the core network through NAS (Non-access stratum) direct transmission over the air interface to initiate a service request. If the terminal is in RRC Idle state, it needs to establish an RRC connection. If the terminal is in RRC Inactive state, it needs to restore the RRC connection and initiate the service establishment process. Taking a terminal in RRC Idle state as an example, when the terminal needs to initiate a service request, it initiates an RRC connection establishment process with the base station. The terminal sends the NAS connection request message (service request) to the core network through NAS direct transmission carried in the RRC signaling. The core network establishes a service connection with the terminal, and then sends the service connection and service-related information to the base station. The base station then establishes a service bearer (RB) between itself and the terminal to carry the service and notifies the terminal with an RRC reconfiguration message. For service requests initiated by terminals in RRC Idle state, the terminal includes an EstablishmentCause message in the RRCSetupRequest message to explain the reason for establishing the RRC connection, and then sends a Service Request NAS message to the core network. For terminals in RRC Inactive state, the terminal includes a ResumeCause message in the RRCResumeRequest or RRCResumeRequest1 message to explain the reason for restoring the RRC connection, and then sends a Service Request NAS message to the core network.

[0117] With the introduction of artificial intelligence, machine learning modules are embedded in various nodes of wireless mobile communication networks, including base stations and terminals. Correspondingly, base stations and terminals possess functions such as model signaling, data processing, and edge computing. Services generated by the application of artificial intelligence in wireless communication networks are a typical example of endogenous services. The characteristics of endogenous services are: both the starting point and the endpoint of the service are within the system, and they do not directly provide services to end users, but are built to solve complex problems in mobile communication systems or improve performance.

[0118] The intrinsic business processes can include learning model sharing, computing power sharing, computing power interaction, cloud processing data sharing, and intelligent task segmentation. For example, in a federated learning system, terminal A performs data preprocessing and transmits the data to other network devices via a base station for inference intermediate results, and then transmits the data to terminal B. Terminal B can infer the final result and report it back to the network devices via the base station.

[0119] Inherent services, characterized by large data flows during data processing and machine learning model transmission, cannot be transmitted as physical layer signaling and must be transmitted as a separate service flow via data bearers. Furthermore, different types of machine learning have varying requirements regarding latency and reliability; for example, inference processes have high latency requirements, while the transmission of inference results and models requires high reliability. Current transmission technologies cannot meet the transmission needs of inherent services and cannot guarantee reliable transmission of inherent service data or signaling.

[0120] To address the aforementioned technical problems, this application provides a method for transmitting embedded services. For embedded services, a specific transmission channel carrying the embedded service is established between the base station and the terminal to ensure reliable transmission of embedded service data or signaling. Specifically, the terminal can send an embedded service establishment request to the base station via air interface signaling; the base station, based on the embedded service establishment request, determines to establish the embedded service and sends embedded service establishment indication information to the terminal; in response to the embedded service establishment indication information, the terminal and the base station designate or establish a radio bearer (RB) carrying the embedded service, thereby enabling the terminal and the base station to transmit embedded service data and / or signaling on the RB. Optionally, the RB includes signaling radio bearers SRB0, SRB1, SRB2, or data radio bearer DRB.

[0121] This application provides a method for transmitting endogenous services, applicable to, for example... Figure 1 The system includes a terminal 11 and a base station 12. The terminal 11 can send an intrinsic service establishment request to the base station 12 via air interface signaling. Based on the intrinsic service establishment request, the base station 12 determines to establish the intrinsic service and sends an intrinsic service establishment indication message to the terminal 11. In response to the intrinsic service establishment indication message, the terminal 11 and the base station 12 designate or establish a radio bearer (RB) to carry the intrinsic service, thereby enabling the terminal 11 and the base station 12 to transmit data and / or signaling of the intrinsic service on the RB.

[0122] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR).

[0123] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0124] The base station involved in this application embodiment can also be other network devices, wherein the base station may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network equipment involved in the embodiments of this application can be a base transceiver station (BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a NodeB in a Wide-band Code Division Multiple Access (WCDMA) system, an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next-generation 5G network architecture, a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of this application.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0126] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0127] Figure 2 A flowchart illustrating the transmission method for endogenous services provided in this embodiment. For example... Figure 2 As shown, this embodiment provides a method for transmitting endogenous services, with the executor being the terminal UE. The specific steps of this method are as follows:

[0128] S201. Send an intrinsic service establishment request to the base station via air interface signaling.

[0129] In this embodiment, the intrinsic services include, but are not limited to, at least one of the following: learning model sharing, computing power sharing, computing power interaction, cloud processing data sharing, and intelligent task segmentation. Because intrinsic services involve large data flows during data processing and machine learning model transmission, they cannot be transmitted as physical layer signaling. Therefore, they can only be transmitted as an independent service flow via data bearer. Furthermore, different types of machine learning have different requirements regarding latency and reliability. For example, the inference process has high latency requirements, and the transmission of inference results and models has high reliability requirements. Therefore, this embodiment considers establishing a specific transmission channel between the base station and the terminal to carry intrinsic services.

[0130] When it is necessary to establish an intrinsic service, the terminal can send an intrinsic service establishment request to the base station through air interface signaling, so that the base station can determine whether to accept the establishment of the intrinsic service based on the intrinsic service request.

[0131] Optionally, sending an intrinsic service establishment request to the base station via air interface signaling includes at least one of the following:

[0132] Method 1: Initiate a random access request to the base station using the preset preamble and / or preset physical random access channel (PRACH) resources corresponding to the endogenous service;

[0133] Method 2: Send a Radio Resource Control (RRC) establishment request message to the base station, wherein the establishment reason contained in the RRC establishment request message is set to the establishment of an endogenous service;

[0134] Method 3: Send an RRC recovery request message to the base station, wherein the recovery reason included in the RRC recovery request message is set to the establishment of an endogenous service;

[0135] Method 4: When the terminal is in RRC connection state, it sends a first RRC signaling to the base station. The first RRC signaling is an intrinsic service establishment request message. The intrinsic service establishment request message includes one or more of the following: intrinsic service establishment request, intrinsic service type, intrinsic service period, intrinsic service life cycle, and intrinsic service QoS requirements.

[0136] In Method 1, a set of dedicated preamble and / or PRACH (Physical Random Access Channel) resources can be pre-associated with one or a class of endogenous services. The terminal can use the dedicated preamble and / or PRACH resources to initiate random access. The base station can determine from the dedicated preamble and / or PRACH resources whether the terminal is initiating an establishment request for a specific endogenous service.

[0137] Optionally, the preset preamble code and / or preset PRACH resources can be obtained through the following process:

[0138] Receive system messages from the radio access network system sent by the base station, the system messages including a preset preamble and / or preset PRACH resources corresponding to the intrinsic service; or

[0139] When the terminal is in an RRC connection state, it receives a second RRC signaling sent by the base station. The second RRC signaling includes a preset preamble and / or preset PRACH resources corresponding to the endogenous service.

[0140] In Method 2, if the terminal is in the RRC Idle state, the terminal needs to send an RRC establishment request message to the base station to establish an RRC connection and enter the RRC Connected state. The establishment reason in the RRC establishment request message can be set to "intrinsic service establishment". That is, "intrinsic service establishment" is added to the EstablishmentCause of the RRC SetupRequest message. After the base station receives the RRC establishment request message, if it determines that the establishment reason in the RRC establishment request message is "intrinsic service establishment", it can determine that the terminal has initiated an intrinsic service establishment request.

[0141] In Method 3, if the terminal is in RRC Inactive state, the terminal needs to send an RRC recovery request message to the base station to restore the RRC connection and put the terminal into the RRC Connected state. The recovery reason in the RRC recovery request message can be set to intrinsic service establishment. That is, "intrinsic service establishment" is added to the ResumeCause of the RRC recovery request message RRCResumeRequest or RRCResumeRequest1. After the base station receives the RRC recovery request message, if it determines that the recovery reason in the RRC recovery request message is intrinsic service establishment, it can determine that the terminal has initiated an intrinsic service establishment request.

[0142] In Method 4, if the terminal is in the RRC Connected state, the terminal can send a first RRC signaling message to the base station. This first RRC signaling message is an intrinsic service establishment request message, which may include, but is not limited to, one or more of the following: intrinsic service establishment request, intrinsic service type, intrinsic service period, intrinsic service lifecycle, and intrinsic service QoS (Quality of Service) requirements (such as data volume, latency, and reliability). The information such as intrinsic service type, intrinsic service period, intrinsic service lifecycle, and intrinsic service QoS (Quality of Service) requirements (such as data volume, latency, and reliability) can be used by the base station to determine which one or more intrinsic services the terminal requests to establish, and to determine the radio bearers (RB) transmission method to use, etc., which is not limited here. It should be noted that a single first RRC signaling message may include the above information for one or more intrinsic services; that is, one first RRC signaling message can request the establishment of one or more intrinsic services.

[0143] It should be noted that the above four methods can be combined without conflict, and this application does not impose any restrictions.

[0144] S202, Receive the native service establishment instruction information sent by the base station.

[0145] In this embodiment, after receiving the native service establishment request sent by the terminal, the base station can determine whether to accept the terminal to establish a native service based on the native service request. After determining to accept the terminal to establish a native service, the base station can send native service establishment indication information to the terminal to indicate that the terminal can establish a native service.

[0146] Optionally, the base station may send any of the following messages to the terminal, which include intrinsic service establishment indication information: RRC connection establishment message, RRC connection reconfiguration message, RRC connection recovery message, and third RRC signaling; wherein the third RRC signaling is a separate RRC signaling, that is, a separate RRC signaling can be used to transmit the intrinsic service establishment indication information. In another optional embodiment, the base station may also send the intrinsic service establishment indication information to the terminal via SRB0.

[0147] Optionally, when it is necessary to use DRB (Data Radio Bearer) as the RB to carry the intrinsic service, and to transmit the data and / or signaling of the intrinsic service on the DRB, the base station needs to carry DRB configuration parameters in the intrinsic service establishment indication information after establishing a dedicated DRB to carry the intrinsic service. The terminal can establish the corresponding DRB according to the DRB configuration parameters, so that the data and / or signaling of the intrinsic service can be transmitted on the DRB between the base station and the terminal.

[0148] S203. Based on the intrinsic service establishment instruction information, transmit the data and / or signaling of the intrinsic service with the base station on the radio bearer RB carrying the intrinsic service.

[0149] In this embodiment, when the terminal receives the native service establishment instruction information sent by the base station, it can determine that the base station accepts the terminal to establish a native service based on the native service establishment instruction information, and then transmit the data and / or signaling of the native service with the base station on the designated RB carrying the native service.

[0150] Among them, the RBs that carry endogenous services include, but are not limited to, SRB0, SRB1, SRB2 or DRB.

[0151] Optionally, the RBs that carry the endogenous business are as follows:

[0152] 1) Without activating air interface security, SRB0 is used as the RB to carry intrinsic services; the base station and the terminal can transmit data and / or signaling of intrinsic services on SRB0. This method is suitable for intrinsic services with low requirements for security and transmission reliability.

[0153] 2) After activating air interface security, SRB1 or SRB2 is used as the RB to carry the intrinsic service; the base station and the terminal can transmit the data and / or signaling of the intrinsic service on SRB1 or SRB2. Alternatively, a new SRBx can also be used as the RB to carry the intrinsic service.

[0154] 3) After activating air interface security, a dedicated DRB for carrying the intrinsic service is established according to the intrinsic service requirements. An intrinsic service establishment instruction message is sent to the terminal, containing DRB configuration parameters. This enables the terminal to establish the corresponding DRB based on the DRB configuration parameters, allowing the base station and the terminal to transmit intrinsic service data and / or signaling on the DRB. Optionally, one or more DRBs can be established for a single intrinsic service.

[0155] 4) If the terminal is in an RRC inactive state, the DRB carrying the intrinsic service pre-stored in the terminal context will be restored without the terminal entering the RRC connected state; the base station and the terminal can transmit the data and / or signaling of the intrinsic service on the restored DRB carrying the intrinsic service.

[0156] The method for transmitting embedded services provided in this embodiment involves a terminal sending an embedded service establishment request to a base station via air interface signaling. The base station determines whether to establish the embedded service based on the request and sends embedded service establishment indication information to the terminal. Subsequently, the base station and the terminal can transmit the embedded service data and / or signaling on the radio bearer (RB) carrying the embedded service. This embodiment treats the embedded service data and / or signaling as an independent service flow, transmitting it on a specific radio bearer between the base station and the terminal, ensuring reliable transmission of the embedded service data and / or signaling.

[0175] The method for transmitting endogenous services provided in this embodiment is the base station-side method in the above embodiments, and is based on the same application concept. Since the principles of the methods and devices for solving problems are similar, the repeated parts will not be described again.

[0176] To further illustrate the above-mentioned method for transmitting endogenous services, the embodiments of this application also provide the following examples for detailed explanation.

[0177] Example 1: Establishing an intrinsic service in an RRC Idle state terminal (1)

[0178] A set of dedicated preamble codes and / or PRACH resources are pre-associated with one or a class of intrinsic services. A terminal can use these dedicated preamble codes and / or PRACH resources to initiate random access. The base station can determine from these dedicated preamble codes and / or PRACH resources whether the terminal is initiating an establishment request for a specific intrinsic service. These dedicated preamble codes and / or PRACH resources are broadcast in the system messages of the radio access network. The base station can send the dedicated preamble / PRACH resource configuration for intrinsic service establishment requests in the system messages.

[0179] In this example, for a terminal in the RRC Idle state, the transmission method for intrinsic services may specifically include:

[0180] Step 1: The terminal reads system messages to determine the dedicated preamble code and / or PRACH resource used for the intrinsic service establishment request;

[0181] Step 2: When the terminal needs to initiate an intrinsic service, it triggers a random access procedure and sends a random access request to the base station using a dedicated preamble code and / or PRACH resources.

[0182] Step 3: The base station receives the random access request sent by the terminal and determines whether the terminal needs to initiate an intrinsic service establishment process based on the dedicated preamble code and / or PRACH resources;

[0183] Step 4: The terminal sends an RRC connection establishment request message to the base station. The reason for the connection establishment request can be "intrinsic service establishment" (optional) or other.

[0184] Step 5: The base station receives the RRC connection establishment request message sent by the terminal and establishes the radio bearer (RB) for the intrinsic service using one of the following methods: the RB can be an SRB or a DRB.

[0185] - Without establishing a connection with the core network, SRB0 is used for data and / or signaling transmission of intrinsic services between base stations and terminals. This method is suitable for intrinsic services with low security and transmission reliability requirements; or

[0186] - After establishing a connection between the terminal and the core network and activating air interface security, use a dedicated SRB (SRB1, SRB2, or a new SRBx) for the transmission of data and / or signaling for intrinsic services; or

[0187] - After establishing a connection between the terminal and the core network and activating air interface security, establish a dedicated DRB (there may be one or more DRBs for carrying internal services) according to the needs of internal services, so as to carry the transmission of data and / or signaling data streams of internal services in the DRB.

[0188] Step 6: The base station sends an intrinsic service establishment indication message to the terminal. This indication message can be sent via an RRC connection establishment message or an RRC connection reconfiguration message, or via SRB0. Optionally, this indication message may include parameters of the intrinsic service, such as DRB ID, Layer 2 configuration (e.g., PDCP, RLC, MAC configuration, etc.) and Layer 1 configuration, etc.

[0189] Step 7: The terminal establishes an RB (Resource Block) to carry the intrinsic service according to the instruction of the base station via an RRC connection establishment message or an RRC connection reconfiguration message, and transmits data and / or signaling of the intrinsic service with the base station on the RB. The RB can be an SRB or a DRB.

[0190] Example 2: Establishing an intrinsic service in an RRC Idle state terminal (2)

[0191] In this example, for a terminal in the RRC Idle state, the transmission method for intrinsic services may specifically include:

[0192] Step 1: When the terminal needs to initiate an intrinsic service, it triggers a random access procedure and sends a random access request to the base station;

[0193] Step 2: The base station receives the random access request sent by the terminal; the base station can respond to the random access request sent by the terminal.

[0194] Step 3: The terminal sends an RRC connection establishment request message to the base station (for example, the RRC connection establishment request is carried by Msg3 or MSGB). The reason for the connection establishment request is "intrinsic service establishment". Optionally, the RRC connection establishment request message can also carry intrinsic service requirement information, such as intrinsic service type, intrinsic service lifecycle, intrinsic service QoS requirements, etc.

[0195] Step 4: The base station receives the RRC connection establishment request message sent by the terminal, and the base station determines that the terminal wants to initiate the intrinsic service establishment process;

[0196] Step 5: Based on the content of the terminal's intrinsic service establishment request, the base station establishes the radio bearer (RB) for the intrinsic service using one of the following methods: the RB can be an SRB or a DRB.

[0197] - Without establishing a connection with the core network, SRB0 is used for native service transmission between the base station and the terminal. This method is suitable for native services with low security and transmission reliability requirements; or

[0198] - After establishing a connection between the terminal and the core network and activating air interface security, use a dedicated SRB (SRB1, SRB2, or a new SRBx) for intrinsic service transmission; or

[0199] - After establishing a connection between the terminal and the core network and activating air interface security, establish a dedicated DRB (there can be one or more DRBs carrying internal services) based on the inherent service requirements, and use the DRB to carry the transmission of the internal service data stream.

[0200] Step 6: The base station sends the intrinsic service establishment indication information to the terminal via an RRC connection establishment message or an RRC connection reconfiguration message; optionally, the intrinsic service establishment indication information includes parameters of the intrinsic service, such as DRB ID, Layer 2 configuration (such as PDCP, RLC, MAC configuration, etc.) and Layer 1 configuration, etc.

[0201] Step 7: The terminal receives an RRC connection establishment message or an RRC connection reconfiguration message sent by the base station. This message carries information indicating the intrinsic service bearer (RB) and its configuration.

[0202] Step 8: The terminal establishes an RB to carry the intrinsic service according to the intrinsic service bearer information indicated by the base station, and transmits the data and / or signaling of the intrinsic service with the base station on the RB. The RB can be an SRB or a DRB.

[0204] In this example, for a terminal in the RRC Idle state, the transmission method for intrinsic services may specifically include:

[0205] Step 1: The terminal initiates a random access procedure and sends an RRC connection establishment request message to the base station (for example, the RRC connection establishment request is carried in Msg3 or MSGB). The reason for the connection establishment request can be "intrinsic service establishment" (optional) or other.

[0206] Step 2: The base station responds to the random access procedure initiated by the terminal; receives the RRC connection establishment request;

[0207] Step 3: The terminal establishes an RRC connection based on the base station's RRC connection establishment message, and then sends an RRC signaling message for "intrinsic service establishment request" to the base station. The signaling message content includes one or more of the following: intrinsic service establishment request, intrinsic service type, intrinsic service periodicity, intrinsic service lifecycle, intrinsic service QoS requirements (such as data volume, latency, reliability), etc. An RRC signaling message for "intrinsic service establishment request" can contain requests for one or more intrinsic services.

[0208] Step 4: After the base station establishes an RRC connection for the terminal, it receives the RRC message "Intrinsic Service Establishment Request" sent by the terminal. Based on the terminal's intrinsic service requirements, it establishes one or more DRBs to carry the intrinsic service. The process of establishing a DRB can be found in the above embodiments.

[0209] Step 5: The base station sends an RRC connection reconfiguration message containing native service bearer configuration information to the terminal. This configuration information includes parameters of the native service, such as native service type, DRB ID, Layer 2 configuration (such as PDCP, RLC, MAC configuration, etc.) and Layer 1 configuration.

[0210] Step 6: The terminal receives the RRC connection reconstruction message, establishes the corresponding DRB according to the configuration information therein, and transmits data and / or signaling of the endogenous service with the base station on the DRB.

[0211] Example 4: A terminal in RRC Inactive state establishes an intrinsic service (1)

[0212] A set of dedicated preamble codes and / or PRACH resources are pre-associated with one or a class of intrinsic services. A terminal can use these dedicated preamble codes and / or PRACH resources to initiate random access. The base station can determine from these dedicated preamble codes and / or PRACH resources whether the terminal is initiating an establishment request for a specific intrinsic service. These dedicated preamble codes and / or PRACH resources are broadcast in the system messages of the radio access network. That is, the base station can send the dedicated preamble / PRACH resource configuration for the intrinsic service establishment request in the system messages, or send it to the terminal via dedicated RRC signaling before the terminal enters the RRC Inactive state.

[0213] In this example, for terminals in the RRC Inactive state, the transmission method for intrinsic services may specifically include:

[0214] Step 1: The terminal reads system messages or uses RRC-specific signaling before entering the RRC Inactive state to determine the dedicated preamble / PRACH resource used for the intrinsic service establishment request;

[0215] Step 2: When the terminal needs to initiate an intrinsic service, it triggers a random access procedure and sends a random access request to the base station using dedicated preamble / PRACH resources;

[0216] Step 3: The base station receives the random access request sent by the terminal and determines that the terminal wants to initiate the intrinsic service establishment process;

[0217] Step 4: The terminal sends an RRC recovery request message (RRCResumeRequest or RRCesumeRequest1) to the base station. The recovery reason, ResumeCause, can be "intrinsic service establishment" (optional) or other.

[0218] Step 5: The base station receives the RRC recovery request message sent by the terminal and establishes the radio bearer (RB) for the endogenous service using one of the following methods: the RB can be an SRB or a DRB.

[0219] - Prevent the terminal from entering connected state, restore the RB carrying the intrinsic service stored in the RRC Inactive state terminal context (UE context), and use this RB to transmit the intrinsic service data stream between the terminal and the UE; or

[0221] - Notify the terminal to enter the connected state and establish a dedicated DRB (there may be one or more DRBs for carrying internal services) according to the needs of the internal services, so as to carry the transmission of data and / or signaling data streams of the internal services in the DRB.

[0222] Step 6: The base station sends an intrinsic service establishment indication message to the terminal. This indication message can be sent via an RRC recovery message, an RRC connection establishment message, or an RRC connection reconfiguration message. Optionally, the indication message may include parameters of the intrinsic service, such as DRB ID, Layer 2 configuration (such as PDCP, RLC, MAC configuration, etc.) and Layer 1 configuration, etc.; and establishes the protocol stack of the radio bearer (RB) for the intrinsic service.

[0223] Step 7: The terminal receives an RRC recovery message, an RRC connection establishment message, or an RRC connection reconfiguration message sent by the base station. This message carries information indicating the native service bearer (RB) and its configuration. Based on the native service parameters carried in the message, the terminal establishes an RB to carry the native service and transmits data and / or signaling for the native service with the base station on this RB. The RB can be an SRB or a DRB.

[0227] Step 2: The base station receives the random access request sent by the terminal and responds to the random access request.

[0228] Step 3: The terminal sends an RRC recovery request message (RRCResumeRequest or RRCesumeRequest1) to the base station (for example, carried by Msg3 or MSGB). The recovery reason is "intrinsic service establishment". Optionally, the RRC recovery request message can also carry intrinsic service requirement information, such as intrinsic service type, intrinsic service lifecycle, intrinsic service QoS requirements, etc.

[0229] Step 4: The base station receives the RRC connection recovery request message sent by the terminal and determines that the terminal wants to initiate the intrinsic service establishment process; it establishes the radio bearer (RB) of the intrinsic service using one of the following methods, where the RB can be an SRB or a DRB;

[0230] - Prevent the terminal from entering the connected state, restore the RB carrying the intrinsic service stored in the inactive terminal context (UE context), and use this RB to transmit the intrinsic service data stream between the terminal; or

[0231] - Notify the terminal to enter connected state and use a dedicated SRB (SRB1, SRB2, or a new SRBx) for native service transmission; or

[0232] - Notify the terminal to enter the connected state and establish a dedicated DRB (there may be one or more DRBs for carrying internal services) based on the needs of the internal services, so as to carry the transmission of the internal service data stream using the DRB.

[0233] Step 5: The base station sends an intrinsic service establishment indication message to the terminal. This indication message can be sent via an RRC recovery message, an RRC connection establishment message, or an RRC connection reconfiguration message. Optionally, the indication message may include parameters of the intrinsic service, such as DRB ID, Layer 2 configuration (such as PDCP, RLC, MAC configuration, etc.) and Layer 1 configuration, etc.; and establishes the protocol stack of the radio bearer (RB) for the intrinsic service.

[0234] Step 6: The terminal receives an RRC recovery message, an RRC connection establishment message, or an RRC connection reconfiguration message sent by the base station. Based on the configuration information therein, the terminal establishes an RB to carry the intrinsic service and transmits the data and / or signaling of the intrinsic service on the RB. The RB can be an SRB or a DRB.
