[0036] Embodiments of the present application will be described in more detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0037] To address the current technical problem that if the terminal needs to send a signaling to the network device, the SDT process will be terminated and restored to the connected state for signaling transmission, resulting in increased power consumption of the terminal. This embodiment provides a communication method, as Figure 1 shown, the method includes:

[0038] Step 101, receiving the configuration information of SDT sent by the network device.

[0039] For the execution subject of this embodiment, it can be a communication device or a communication device, which can be configured on the terminal device side, such as an electronic device or a chip, etc. Before the network device and the terminal device start data transmission, the terminal device can receive the configuration information (SDT-Config) of SDT sent by the network device, perform radio resource configuration, and establish a radio resource control (RRC) connection between the terminal device and the network device to facilitate data or signaling transmission. Correspondingly, in a wireless communication system, the RRC state of the terminal device can include the idle state (RRC_IDLE), the connected inactive state (RRC_INACTIVE), and the connected state (RRC_CONNECTED); RRC can be used for radio resource management, control, and scheduling. Under the premise of meeting the quality of service requirements, it can fully improve the effective utilization of system resources, prevent network congestion, and maintain the smallest possible signaling load.

[0040] In some examples, the method shown in this embodiment may be executed by a terminal device, which may be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may also be an automobile with communication functions, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, or may also be a chip or a chip system, etc. The embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0041] In an embodiment of the present application, the network device may be a device such as a base station or a satellite, and is not specifically limited in the embodiments of the present application. The network device may be an entity on the network side for transmitting or receiving signals. For example, the network may be a communication satellite, an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the network device. The network device provided by the embodiments of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. Adopting the CU-DU structure can split the protocol layer of the network device, such as a base station. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0042] Step 102: Determine the signaling bearer resources reserved by the network device according to the configuration information.

[0043] In a specific application scenario, based on the received configuration information, the terminal can determine the signaling bearer resources reserved by the network device for it. The terminal can transition from the connected state to the connected inactive state, and then use the reserved signaling bearer resources for signaling and data transmission, optimize the radio bearer configuration for data transmission between the terminal and the network, improve the transmission efficiency, and enhance the user experience. Specifically, the signaling bearer resources can be the radio bearers reserved by the network device for the terminal to transmit signaling when the terminal is in the connected state. For example, Signaling Radio Bearer Type 2 (SRB2).

[0044] Exemplarily, if the network device does not reserve signaling bearer resources, when the terminal has signaling to send during the SDT process, since there is no configured SRB2 for the SDT process, it cannot send the message carrying the signaling, resulting in the termination of the SDT process. It is necessary to enter the RRC_CONNECTED state through the connection recovery process and then send the signaling.

[0045] Step 103: When the terminal is in the connected inactive state, send signaling to the network device through the SDT process based on the signaling bearer resources.

[0046] For this embodiment, when the terminal enters the RRC_INACTIVE state and there is signaling that needs to be sent through the ULInformationTransfer message, or when there is signaling that needs to be sent during the SDT data transmission process, since the network device has reserved SRB2 resources, the terminal can directly use SRB2 to send the message, and the network device can also normally receive and process the message on SRB2. In this way, when the terminal has signaling that needs to be transmitted during the SDT process, it does not need to perform the connection recovery process, avoiding the termination of the SDT process due to signaling transmission and reducing the terminal power consumption.

[0047] Compared with the current existing technologies, this embodiment can determine the signaling bearer resources reserved by the network device according to the received SDT configuration information sent by the network device. In this way, when the terminal is in the connected inactive state, it can directly use the reserved signaling bearer resources to send signaling to the network device through the SDT process. In this way, when the terminal has signaling that needs to be transmitted during the SDT process, it does not need to perform the connection recovery process, avoiding the termination of the SDT process due to signaling transmission and reducing the terminal power consumption.

[0048] Further, to illustrate the specific implementation process of the method in this embodiment, this embodiment provides the following Figure 2 specific method, where the method includes:

[0049] Step 201: When the terminal is in the connected state, receive a first connection release message sent by a network device, where the first connection release message carries configuration information.

[0050] Exemplarily, Figure 3 A single-device communication scenario of a wireless communication system is shown. The wireless communication system may include a 5G network, a 5G base station, a terminal, etc. The 5G base station may send a system information radio signal carrying the wireless communication system, and the terminal within the 5G network coverage range around the 5G base station receives the system information, and then the terminal accesses network services through the 5G base station.

[0051] In a specific application scenario, when the terminal is in the connected state, it may receive a first connection release message (RRC Release) sent by the network device. Among them, the first connection release message carries configuration information, and the configuration information may include radio bearer information reserved by the network device for the terminal. For example, data radio bearer information (DRB) and signalling radio bearer information (SRB).

[0052] Optionally, the method of this embodiment may further include: triggering the terminal to enter the connected inactive state according to the first connection release message.

[0053] Specifically, after receiving the first connection release message, the terminal may transition from the RRC_CONNECTED state to the RRC_INACTIVE state in response to the configuration information carried in the first connection release message.

[0054] Step 202: Determine the signalling bearer resources reserved by the network device according to the configuration information.

[0055] As a possible implementation manner, the network device may default to reserve SRB2 resources for the SDT process for the terminal. Regardless of whether the sdt-SRB2-Indication-r17 flag bit in the SDT-Config-r17 field of the configuration information is set to allowed, after the terminal receives the configuration information and confirms the reserved signalling bearer resources, it enters the RRC_INACTIVE state, reducing the terminal power consumption and improving the user experience.

[0056] Step 203: Send a connection recovery message to the network device, and start the SDT process after the RACH SDT process is successful or after the CG SDT process is successful.

[0057] For this embodiment, when the terminal needs to send a signaling in the RRC_INACTIVE state, it can send a connection resume message (RRC Resume or RRC Resume1) to the network device, and then start the SDT process using methods such as the Random Access Channel (RACH) or Configured Grant (CG) to perform signaling transmission. Among them, the RACH can be used to send a random access request to the network device to establish a wireless connection, enabling the terminal to autonomously select an available channel to start the SDT process; the CG can be used for the terminal to directly send data to the network device without sending a scheduling request for uplink data transmission.

[0058] Step 204: Send the signaling to the network device through the ULInformationTransfer message by the SRB corresponding to the signaling bearer resource.

[0059] For this embodiment, in the SDT process, since the network has reserved SRB2 SDT resources, the terminal can send the signaling to the network device through the UEInformationTransefer message by the SRB2 corresponding to the signaling bearer resource, and then perform subsequent data transmission. The network device can normally receive and process the message on SRB2 without performing a connection resume process, improving the information transmission efficiency.

[0060] Optionally, the method of this embodiment may further include: the terminal can send data to the network device through the SDT process.

[0061] Step 205: Receive the second connection release message sent by the network device, and end the SDT process according to the second connection release message.

[0062] For this embodiment, after the data transmission ends, the network device can send a second connection release message (RRC Release) to the terminal to end the SDT process. Among them, the second connection release message can be used to release the established radio bearers and all wireless resources, or only pause the RRC connection when SRB2 is established and accompanied by at least one DRB, including pausing the established wireless bearers.

[0063] To illustrate the specific implementation process of this embodiment, the following specific application examples are given, but not limited to this:

[0064] As Figure 4 shown, for the SDT process initiated by signaling transmission of the UE, the following steps can be executed:

[0065] a1. When the UE is in the RRC_CONNECTED state and receives an RRC Release message sent by the network (NW) with SDT-Config included, it enters the RRC_INACTIVE state;

[0066] b1. When the UE is in the RRC_INACTIVE state and has signaling data to send, it sends an RRC Resume or RRC Resume1 message to the network. After the RACH SDT or CG SDT process is successful, the SDT process starts;

[0067] c1. Since the network has reserved SRB2 SDT resources, the UE can send the signaling through the UEInformationTransefer message via SRB2 to the network, and the network can also normally receive and process the messages on SRB2 without performing a connection restoration process;

[0068] d1. The UE continues to send signaling and data to the network through the SDT process;

[0069] e1. The network sends an RRC Release message, and the SDT process ends.

[0070] As Figure 5 shown, when the UE has signaling to send during the SDT process of data transmission, the following steps can be executed:

[0071] a2. When the UE is in the RRC_CONNECTED state and receives an RRC Release message sent by the network with SDT-Config included, it enters the RRC_INACTIVE state;

[0072] b2. When the UE has data to send in the RRC_INACTIVE state, it can send an RRC Resume or RRC Resume1 message to the network. After the RACH SDT or CG SDT process is successful, the SDT process starts;

[0073] c2. The UE continues to send data to the network through the SDT process;

[0074] d2. When the UE has signaling to send, since the network has reserved SRB2 SDT resources, the UE can send the signaling through the UEInformationTransefer message via SRB2 to the network, and the network can normally receive and process the messages on SRB2 without performing a connection restoration process;

[0075] e2. The UE continues to send signaling and data to the network through the SDT process;

[0076] f2. The network sends an RRC Release message, and the SDT process ends.

[0077] Compared with the current existing technologies, in this embodiment, according to the first release message, it can be converted to the connected inactive state, and the signaling is sent to the network device through the ULInformationTransfer message by the SRB2 corresponding to the signaling bearer resource, simplifying the information interaction process between the terminal and the network device, reducing the access process time, and improving the user's access experience.

[0078] Further, as Figure 1 and Figure 2 a specific implementation of the method shown, this embodiment provides a communication device, as Figure 6 shown, the device includes: a receiving module 31, a determining module 32, and a sending module 33.

[0079] The receiving module 31 is configured to receive the configuration information of the SDT sent by the network device;

[0080] The determining module 32 is configured to determine the signaling bearer resources reserved by the network device according to the configuration information;

[0081] The sending module 33 is configured to send signaling to the network device through the SDT process based on the signaling bearer resources when the terminal is in the connected inactive state.

[0082] In some examples of this embodiment, the receiving module 31 is specifically configured to receive a first connection release message sent by the network device when the terminal is in the connected state, and the configuration information is carried in the first connection release message.

[0083] In some examples of this embodiment, the receiving module 31 is further configured to trigger the terminal to enter the connected inactive state according to the first connection release message.

[0084] In some examples of this embodiment, the sending module 33 is configured to send the signaling to the network device through the ULInformationTransfer message by the SRB corresponding to the signaling bearer resource.

[0085] In some examples of this embodiment, the sending module 33 is specifically further configured to receive a second connection release message sent by the network device; and end the SDT process according to the second connection release message.

[0086] In some examples of this embodiment, the sending module 33 is specifically further configured to send a connection recovery message to the network device, and start the SDT process after the RACH SDT process is successful or after the CG SDT process is successful.

[0087] In some examples of this embodiment, the sending module 33 is specifically further configured to send data to a network device through the SDT process.
