[0048] Before the embodiments of the present application are described, the related art will be briefly introduced as follows:

[0049] I. Introduction to Non-terrestrial networks (NTN)

[0050] A typical NTN deployment scenario is shown in FIG. 2. The link between the user equipment (UE) and the satellite is called the service link, and the link between the satellite and the ground gateway is called the feeder link.

[0051] NTN communication systems include two types: a transparent payload-based NTN communication system and a regenerative payload-based NTN communication system. In 3GPP Release 17 (R17) and Release 18 (R18), only the transparent payload-based NTN communication system is considered. In this deployment environment, the terminal, base station, and core network equipment are all deployed on the ground, and the communication data between the terminal and the network equipment is transferred via an air satellite. In this system, the satellite only forwards the data between the base station and the terminal and does not decode and process the data. In 3GPP Release 19 (R19), the NTN system is extended to a regenerative payload-based NTN system. In this deployment environment, the satellite has all the functions of the base station and can decode and process uplink or downlink data.

[0052] Based on the orbital height of the satellite, NTN communication systems are divided into high, low, and medium orbit satellite communication systems. Among them, the high orbit satellite is commonly a geostationary orbit (GEO) satellite, with an orbital height of 35786 kilometers and relative to the ground. The common orbital height range of the low earth orbit (LEO) satellite is 600-1200 km. The common orbital height range of the medium earth orbit (MEO) satellite is 2000-10000 km.

[0053] II. Introduction to Cellular Internet of Things (CIoT) Evolved Packet System (EPS) Optimization

[0054] In order to send CIoT data to the CIoT application server, the cellular Internet of Things (CIoT) defines two data transmission methods in the EPS:

[0055] (1) Control Plane (CP) CIoT EPS Optimization Scheme

[0056] Under this scheme, the data transmission path can be: UE-RAN-MME-Service Capability Exposure Function (SCEF)-CIoT service application (service application), or UE-RAN-MME-Serving Gateway (SGW)-Packet Gateway (PGW)-CIoT service application.

[0057] Under this scheme, no data radio bearer (DRB) is established between the UE and the RAN, and service data is transmitted through a signalling radio bearer (SRB). That is, service data is encapsulated in a non-access stratum (NAS) message and sent as a container of a radio resource control (RRC) message. It can be understood that, since service data is transmitted through a signalling radio bearer, this data transmission scheme is generally understood as a control plane scheme.

[0058] The control plane CIoT optimization scheme reduces signalling interaction between the terminal and the network side, and can effectively reduce overhead.

[0059] (2) User plane CIoT EPS optimization scheme

[0060] Under this scheme, the data transmission path is: UE-RAN-SGW-PGW-CIoT service application.

[0061] Under this scheme, IoT data is transmitted on a DRB, like traditional data traffic. It can be understood that, since service data is transmitted through a data radio bearer, this data transmission scheme is generally understood as a user plane scheme.

[0062] In addition, the above-mentioned control plane scheme and user plane scheme are also applicable to a 5G system (5GS) scenario. They are respectively referred to as a control plane (CP) CIoT 5GS optimization scheme and a user plane (UP) CIoT 5GS optimization scheme. The data transmission manner is similar to the EPS scenario in principle, and thus will not be described here.

[0063] III. Introduction to long time evolution (LTE) narrow band Internet of Things (NB-IoT)

[0064] LTE NB-IoT is a low power wide area network technology standard for connecting various smart sensors and devices using wireless cellular network and providing long distance, wide coverage and high reliability of communication services. LTE NB-IoT is developed on the basis of LTE standard and can be understood as a simplified version of LTE. Compared with LTE, the following procedures are not supported for NB-IoT UE: connected mode mobility management (such as handover and measurement reporting), inter-radio access technology (RAT) cell reselection, inter-RAT mobility in connected mode, RRC inactive state (RRC_INACTIVE), carrier aggregation (CA), dual connectivity (DC), and the like.

[0065] For the control plane EPS optimization scheme, for NB-IoT, RRC connection reconfiguration is not supported, DRB is not used, access stratum (AS) security processing is not used, a packet data convergence protocol (PDCP) entity is not used, and only SRB1bis (without PDCP entity) is used to transmit data. For a terminal transmitting data through the control plane scheme, a signaling bearer SRB1bis is established in the RRC connection establishment process. In the RRC establishment process, a NAS message carrying downlink data can be transmitted through the RRC connection setup (RRCConnectionSetup) message via SRB0, and a NAS message carrying uplink data can be transmitted through the RRC connection complete (RRCConnentionComplete) message via SRB1bis. After entering the connected mode, a NAS message carrying downlink data can be transmitted through the downlink information transmission (DLInformationTransfer-NB) message via SRB1bis, and a NAS message carrying uplink data can be transmitted through the uplink information transmission (ULInformationTransfer-NB) message via SRB1bis.

[0066] For the user plane EPS optimization scheme, before AS security is activated, the NB-IoT terminal uses SRB1bis (without PDCP entity) to transmit RRC messages and / or NAS messages. After AS security is activated, the NB-IoT terminal uses SRB1 (with PDCP entity) to transmit RRC messages and / or NAS messages.

[0067] In addition, NB-IoT technology is designed for low-rate / latency-insensitive service data transmission at the beginning, and therefore does not support real-time services such as IMS voice.

[0068] IV. Introduction of Voice over LTE (VoLTE)

[0069] VoLTE is based on IMS system to transmit voice services. Among them, the IMS signaling required for voice session establishment and voice service packets are transmitted in LTE system through DRB. In LTE, adaptive multi-rate compression (AMR) voice coding scheme is commonly used. The common voice model generates a voice service packet every 20 ms, and the size of each voice service is related to the AMR coding rate used. For example, if the AMR coding rate is 4.75 kbs, then the size of each original voice service packet is 95 bits.

[0070] V. Introduction of Semi-Persistent Scheduling (SPS)

[0071] Data transmission requires radio resources. There are two ways of resource scheduling: dynamic scheduling and semi-persistent scheduling. Among them, dynamic scheduling relies on downlink control information (DCI) to dynamically allocate radio resources, while semi-persistent scheduling allows semi-static configuration of radio resources and periodically allocates the resources to a specific terminal. In LTE, the RRC connection reconfiguration message is used to configure the period of SPS resources and the SPS scrambling code (such as SPS cell radio network temporary identifier (C-RNTI)), and DCI signaling is used to indicate the starting resource position of SPS resources. Simply put, SPS has the feature of "one allocation, multiple use", that is, it does not need to issue DCI in each resource use period, thereby reducing the overhead of physical downlink control channel (PDCCH), and is usually suitable for periodic service data transmission.

[0072] High-orbit satellite communication has the advantages of wide coverage and high industry maturity, and has great potential in voice communication demand in remote environments such as oceans and deserts. At present, 3GPP is studying to support narrowband voice through high-orbit satellites, so as to realize real-time voice communication of users through high-orbit satellites by mobile phones, which will greatly expand the boundary of communication services. However, in the related art, NB-IoT does not support the transmission of service data with periodic characteristics, such as IMS voice service. In addition, for the control plane optimization scheme, because the related art does not support RRC connection reconfiguration, the current narrowband system cannot support the configuration of SPS resources for the transmission of service data with periodic characteristics, such as voice service packets.

[0073] In view of this, the embodiments of the present application provide a data transmission method, a data transmission device and a communication device to solve the problem that the narrowband Internet of Things cannot support the transmission of service data with periodic characteristics in the related art.

[0074] The data transmission method and resource configuration method provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios.

[0075] FIG. 3 shows a flowchart of a data transmission method according to an embodiment of the present application. As shown in FIG. 3, the data transmission method comprises the following steps:

[0076] Step 301: A terminal receives semi-static resources configured by an access network device;

[0077] Step 302: The terminal transmits data based on the semi-static resources;

[0078] The terminal is a terminal that transmits data based on a control plane scheme.

[0079] The control plane scheme can be a CP CIoT EPS optimization scheme or a CP CIoT 5GS optimization scheme. As described in the foregoing related art, the terminal that transmits data based on the control plane scheme can be understood as a terminal that transmits data based on a signaling radio bearer.

[0080] The access network device can be understood as a base station. The access network device can be a non-terrestrial access network device (such as an NTN base station) or a terrestrial access network device (such as a TN base station).

[0081] Optionally, the terminal is a non-terrestrial terminal. That is, the terminal can be an NTN terminal, that is, a terminal accessing an NTN network.

[0082] The semi-static resource can be an SPS resource, for example. The semi-static resource has the characteristics of one-time allocation and multiple use, and does not need to be allocated with downlink control signaling in each resource use period, and is suitable for transmission of service data with periodic characteristics. Therefore, the terminal can transmit service data with periodic characteristics based on the semi-static resource.

[0083] In the embodiments of the present application, a terminal receives semi-static resources configured by an access network device, and transmits data based on the semi-static resources. The terminal is a terminal that transmits data based on a control plane scheme. In this way, the terminal that transmits data based on the control plane scheme can transmit service data with periodic characteristics based on the semi-static resources, and the NB-IoT that transmits data based on the control plane scheme can also transmit service data with periodic characteristics. In the embodiments of the present application, the terminal that transmits data based on the control plane scheme transmits data by using the semi-static resources. On the one hand, this can avoid system signaling overhead caused by obtaining transmission resources by using a dynamic scheduling mode. On the other hand, this can avoid data transmission delay caused by obtaining transmission resources by using the dynamic scheduling mode, and can ensure that data is transmitted as soon as possible.

[0084] In some embodiments, the terminal transmits data based on the semi-static resources, including:

[0085] The terminal transmits voice-related data based on the semi-static resources.

[0086] The voice-related data includes at least one of voice signaling data and voice service data.

[0087] In this way, the NB-IoT can support real-time services such as IMS voice.

[0088] In some embodiments, the terminal receives semi-static resources configured by an access network device, including any one of the following:

[0089] In the connection establishment process, the terminal receives semi-static resource parameters configured by the access network device.

[0090] After the connection establishment process is completed, the terminal receives semi-static resource parameters configured by the access network device.

[0091] That is, the access network device can configure semi-static resource parameters for the terminal in the process in which the terminal accesses the base station, or the access network device can configure semi-static resource parameters for the terminal after the terminal accesses the base station. The semi-static resource parameters can be understood as or replaced by SPS parameters.

[0092] The semi-static resource parameters can include at least one of the following:

[0093] Semi-static resource parameters for uplink transmission;

[0094] a semi-static resource parameter for downlink transmission;

[0095] a semi-static resource parameter for both uplink transmission and downlink transmission.

[0096] Optionally, in the case that the semi-static resource parameter is configured in the connection setup procedure, the semi-static resource parameter is carried by a connection setup message; or,

[0097] in the case that the semi-static resource parameter is configured after the completion of the connection setup procedure, the semi-static resource parameter is carried by a connection reconfiguration message.

[0098] The connection setup message can be, for example, an RRC connection setup message (such as RRCConenctionSetup-NB).

[0099] The connection reconfiguration message can be transmitted through a signaling-bearer SRB1bis. The connection reconfiguration message can be, for example, an RRC connection reconfiguration message (such as RRCConenctionReconfiguration).

[0100] In this embodiment, by introducing the connection reconfiguration message, the terminal can be configured with semi-static resources for transmitting data based on the control plane scheme. On the one hand, the impact on the existing message (such as RRCConenctionSetup-NB) is reduced, and on the other hand, it can be ensured that the semi-static resources are configured only when the terminal needs to use the semi-static resources, that is, the semi-static resources are configured on demand, thereby avoiding the situation that the semi-static resources are configured for the terminal in the case of failed voice call setup, and reducing resource consumption.

[0101] In some embodiments, the semi-static resource parameter comprises one or more of the following:

[0102] period information of the semi-static resource;

[0103] available Hybrid Automatic Repeat Request (HARQ) process information of the semi-static resource;

[0104] start resource information of the semi-static resource;

[0105] scheduling scrambling information of the semi-static resource.

[0106] In some embodiments, the above semi-static resource parameters can be provided by an RRC message. For example, the RRC message provides the period information and the scheduling scrambling information of the semi-static resource, etc.

[0107] In some embodiments, the semi-static resource parameters described above can be provided through physical layer control signaling (e.g., DCI). For example, the resource starting position information is provided through physical control signaling. In this example, before the access network device provides the starting resource information of the semi-static resource through the physical layer control signaling, the terminal can provide the recommended or suggested or preferred semi-static periodicity information to the access network device. Based on the reported semi-static resource periodicity information and the starting resource position information provided by the physical layer control signaling, the terminal can determine the periodic semi-static resource.

[0108] The periodicity information of the semi-static resource can be the periodicity of the semi-static resource or the semi-static scheduling interval, such as 128 subframes. It can be understood that the interval of the semi-static resource is 128 subframes.

[0109] The available HARQ process information of the semi-static resource can be, for example, the number of available HARQ processes or the HARQ process number of the semi-static resource, etc.

[0110] The starting resource information of the semi-static resource can be understood as the starting position information of the resource. The resource starting position information can include the starting position information of the uplink semi-static resource and / or the starting position information of the downlink semi-static resource.

[0111] The scheduling scrambling information of the semi-static resource can be the SPS scrambling code (e.g., SPS C-RNTI).

[0112] In some embodiments, in the case where the scheduling scrambling information of the semi-static resource is not provided, the terminal uses the C-RNTI (Cell-Radio Network Temporary Identifier) by default.

[0113] In some embodiments, the scheduling scrambling information of the semi-static resource is agreed by the protocol, for example, SPS C-RNTI = FFF8. In this case, the semi-static resource parameters described above can not carry the scheduling scrambling information of the semi-static resource.

[0114] In some embodiments, in the case where the semi-static resource parameters do not include the available HARQ process information of the semi-static resource, the available HARQ process of the semi-static resource is the default configured HARQ process.

[0115] For example, in the case that the number of available HARQ processes of the semi-static resource is default, the terminal defaults N available HARQ processes. Wherein, N is an agreed value, for example, can be 1 or 2. The HARQ process number corresponding to the default N HARQ processes can also be agreed by the protocol. For example, in the case that there is only one available HARQ process by default, the corresponding HARQ process number HARQ Process ID = 0. In the case that there are two available HARQ processes by default, the corresponding HARQ process number HARQ Process ID = 0, 1.

[0116] It should be noted that, in the case that the semi-static resource parameter includes the available HARQ process information of the semi-static resource, the available HARQ process information of the semi-static resource can be the default HARQ process information.

[0117] In some embodiments, the method further comprises:

[0118] The terminal receives the first control signaling sent by the access network device, and the first control signaling is used to provide the starting resource information of the semi-static resource.

[0119] The first control signaling can be understood as the activation indication information of the semi-static resource. The first control signaling activates the semi-static resource by providing the starting resource information of the semi-static resource.

[0120] For example, in the case that the semi-static resource parameter does not include the starting resource information, the access network device can send the activation indication information of the semi-static resource to the terminal.

[0121] For example, in the case that the semi-static resource parameter includes the starting resource information, the access network device can send the first control signaling to the terminal, and the first control signaling can be used to adjust the starting resource information of the semi-static resource.

[0122] In some examples, the access network device can provide the first control signaling to the terminal multiple times for adjusting the starting resource information of the semi-static resource. For example, the access network device can provide the first control signaling to the terminal multiple times according to the actual situation of the service.

[0123] The activation indication information of the semi-static resource can be the activation indication information of the UL semi-static resource and / or the activation indication information of the DL semi-static resource.

[0124] The first control signaling can be, for example, DCI, which can be scrambled by SPS C-RNTI.

[0125] Optionally, the terminal receiving the first control signaling sent by the access network device further comprises:

[0126] The terminal stores the semi-static resource configured by the access network device and corresponding HARQ information based on the first control signaling. In some embodiments, the first control signaling also carries periodic information of the semi-static resource.

[0127] It should be noted that, in the case that the first control signaling carries periodic information of the semi-static resource, the terminal can consider that the periodicity of the semi-static resource configured by the first control signaling overrides or is prior to the periodicity of the semi-static resource configured by the RRC message.

[0128] Optionally, the periodic information of the semi-static resource includes any of the following:

[0129] Periodicity bitmap of the semi-static resource;

[0130] Periodicity of the semi-static resource;

[0131] Periodicity index of the semi-static resource.

[0132] For example, the protocol can agree that the periodicity of the semi-static resource includes {20ms, 40ms, 80ms}, and the periodicity bitmap of the semi-static resource can be 3 bits, each bit corresponding to the agreed periodicity. For example, the periodicity bitmap of the semi-static resource = 010 can be used to indicate that the periodicity of the semi-static resource is 40ms.

[0133] The periodicity of the semi-static resource may, for example, be SPS periodicity = 40ms.

[0134] The periodicity index of the semi-static resource may, for example, be SPS index. For example, in the case that the semi-static resource parameter includes multiple SPS periodicities (such as SPS periodicity list), the first control signaling can carry SPS index, which corresponds to the multiple SPS periodicities in the semi-static resource parameter. For example, when the SPS periodicity of the semi-static resource includes a first SPS periodicity, SPS index = 1; when the SPS periodicity of the semi-static resource includes a second SPS periodicity, SPS index = 2.

[0135] In some embodiments, before the access network device configures the semi-static resource to the terminal, the access network device obtains mode information of the service from the core network device, such as at least one of service periodicity information, service packet size, service arrival time, and service flow direction.

[0136] In some embodiments, before the access network device configures the semi-static resource to the terminal, the access network device obtains mode information of the service from the terminal, such as at least one of service periodicity information, service packet size, service arrival time, and service flow direction.

[0137] In some embodiments, before the terminal receives the semi-static resource configured by the access network device, the method further comprises:

[0138] The terminal reports first semi-static resource assistance information to the access network device;

[0139] The first semi-static resource assistance information is used to assist the access network device to configure the semi-static resource.

[0140] The terminal reporting the first semi-static resource assistance information to the access network device can be understood as the terminal sending recommended semi-static resource parameters to the access network device. It can also be understood that the terminal recommends semi-static resource parameters to the access network device after the RRC connection establishment process is completed.

[0141] As an implementation manner, the terminal reports the first semi-static resource assistance information to the access network device before the terminal receives the first control signaling sent by the access network device. At this time, the first control signaling is used to configure (or can be understood as activate) semi-static resources for the terminal, that is, step 301 is realized by the terminal receiving the first control signaling sent by the access network device.

[0142] For the access network device, the access network device can configure or activate semi-static resources for the terminal based on the assistance information reported by the terminal. By the terminal reporting the first semi-static resource assistance information to the access network device, the access network device can better configure or activate semi-static resources.

[0143] Optionally, the first semi-static resource assistance information includes at least one of the following:

[0144] Period information of the semi-static resource;

[0145] Available HARQ process information of the semi-static resource.

[0146] For example, the semi-static resource period recommended by the terminal can be 40ms.

[0147] The available HARQ process information of the semi-static resource can include the number of available HARQ processes of the semi-static resource or HARQ process ID and the like. It should be noted that in the case where the number of available HARQ processes of the semi-static resource is default, N available HARQ processes are recommended by default. Wherein, N is an agreed value, for example, can be 1 or 2. The HARQ process number corresponding to the default N HARQ processes can also be a protocol agreement. For example, in the case of defaulting to only one available HARQ process, the corresponding HARQ process number HARQ Process ID = 0. In the case of defaulting to two available HARQ processes, the corresponding HARQ process number HARQ Process ID = 0, 1.

[0148] Optionally, the first semi-static resource assistance information is reported by any of the following manners:

[0149] The first semi-static resource assistance information is reported by an RRC message; wherein the RRC message is transmitted by signaling bearing SRB1bis;

[0150] The first semi-static resource assistance information is reported by a Medium Access Control Control Element (MAC CE); wherein the MAC CE is identified by a first Logical Channel Identity (LCID), and the first Logical Channel Identity is a logical channel identity dedicated for semi-static resource assistance information.

[0151] For example, the MAC CE can include a period information field, which is used to indicate the recommended SPS period. Alternatively, the MAC CE can include a bit map. For example, it is agreed that the SPS resource period is {20ms, 40ms, 80ms}, and the bit map can be 3 bits, each bit corresponding to an agreed period. For example, the bit map 010 can be used to indicate that the SPS period is 40ms.

[0152] In some embodiments, before the terminal receives the semi-static resource configured by the access network device, the method further comprises:

[0153] During the connection establishment process, the terminal provides second semi-static resource assistance information to the access network device;

[0154] Wherein, the second semi-static resource assistance information is used to assist the access network device to configure the semi-static resource.

[0155] In this embodiment, the terminal can provide the access network device with semi-static resource assistance information (may be referred to as SPS assistance information) before the access network device configures the semi-static resource parameters.

[0156] It should be noted that after the terminal provides the access network device with the second semi-static resource assistance information, the terminal can also provide the access network device with the first semi-static resource assistance information.

[0157] In some embodiments, the second semi-static resource assistance information includes one or more of the following:

[0158] The first indication indicates that the connection establishment is caused by a voice call;

[0159] The second indication indicates that the connection establishment is caused by an emergency call;

[0160] The third indication indicates a request for the access network device to configure semi-static resources;

[0161] The fourth indication indicates a request for a voice dedicated signaling radio bearer.

[0162] For example, the cause of the RRC connection establishment can be a calling voice (mo-VoiceCall). For example, the terminal can carry an RRC connection establishment cause field in the RRC connection establishment request message, and the field is set to calling voice.

[0163] For example, the terminal can carry an RRC connection establishment cause field in the RRC connection establishment request message, and the field is set to emergency call.

[0164] The third indication can be understood as semi-static resource configuration request information. For example, the terminal can carry semi-static resource configuration request information in the RRC connection establishment request message.

[0165] The fourth indication can be understood as voice dedicated signaling radio bearer request information. The voice dedicated signaling radio bearer can be understood as a signaling radio bearer used only for transmitting voice-related data (such as voice service data). For example, the terminal can carry voice dedicated signaling radio bearer request information in the RRC connection establishment request message. Based on this, the access network device can know that the terminal has a request to transmit voice-related data, and can then configure semi-static resources for the terminal.

[0166] The semi-static resource configuration request information (such as SPSConfigurationRequest) can be a one-bit indication field. For example, in the case of carrying semi-static resource configuration request information in the RRC connection establishment request message, or the semi-static resource configuration request information being set to "true", the access network device configures the semi-static resource parameters for the terminal.

[0167] For example, the semi-static resource configuration request information can be request information common to uplink and downlink. For example, in a case where the terminal provides the semi-static resource configuration request information to the base station, the base station defaults that the terminal requests configuration of uplink and downlink SPS. The semi-static resource configuration request information can also be request information for uplink or downlink respectively. For example, SPSConfigurationRequest-UL is used to request configuration of uplink semi-static resources, and SPSConfigurationRequest-DL is used to request configuration of downlink semi-static resources.

[0168] Optionally, in a case where the terminal is a called terminal, the semi-static resource parameter is configured by default by the access network device. For example, the terminal is a called terminal, and the access network device triggers the terminal to establish an RRC connection through a paging mechanism. In a case where the terminal accesses the base station, the access network device configures the semi-static resource parameter for the terminal by default.

[0169] In some embodiments, the method further comprises:

[0170] The terminal sends first confirmation information to the access network device, and the first confirmation information is used to indicate that the terminal has activated the semi-static resource.

[0171] The first confirmation information can be carried by a MAC CE. Optionally, the MAC CE is identified by a newly introduced LCID. Optionally, the LCID is an LCID agreed by a protocol for voice service.

[0172] In some embodiments, the method further comprises:

[0173] The terminal receives second control signaling sent by the access network device, and the second control signaling is used to instruct the terminal to release the semi-static resource.

[0174] The second control signaling can be understood as carrying semi-static resource release indication information, which is used to instruct the terminal to release the semi-static resource. Optionally, the terminal can clear the semi-static resource configured by the access network device based on the semi-static resource release indication information.

[0175] In some embodiments, the method further comprises:

[0176] The terminal sends second confirmation information to the access network device, and the second confirmation information is used to indicate that the terminal has released the semi-static resource.

[0177] The second confirmation information can be carried by a MAC CE. Optionally, the MAC CE is identified by a newly introduced LCID. Optionally, the LCID is a protocol-agreed LCID dedicated for voice service.

[0178] The above is a method embodiment on the terminal side. The following describes a method embodiment on the access network device side.

[0220] Optionally, the second semi-static resource assistance information comprises one or more of the following:

[0221] A first indication indicating that the connection establishment is caused by a voice call;

[0222] A second indication indicating that the connection establishment is caused by an emergency call;

The semi-static resource release assistance information includes indication information that the voice session has ended.

[0232] Optionally, the method further comprises:

[0233] The access network device receives second confirmation information sent by the terminal, and the second confirmation information is used to indicate that the terminal has released the semi-static resource.

[0234] The related description of the embodiments of the present application can be referred to the related description of the method embodiments of FIG. 3, and the same technical effects can be achieved. To avoid repetition, this will not be described here.

[0235] The following provides a plurality of specific embodiments, which exemplarily illustrate the interaction process between the terminal and the access network device. In the following embodiments, the access network device is uniformly referred to as the base station, and the semi-static resource parameter is uniformly referred to as the SPS parameter.

[0236] Embodiment 1: configuring SPS related parameters in RRC connection establishment process

[0237] As shown in FIG. 5, the following steps are included:

[0238] Step 1: In the RRC connection establishment process, the terminal receives the SPS parameter configured by the base station.

[0239] The terminal is a control plane narrowband Internet of Things (CP NB-IoT) terminal. Further, the terminal is an NTN terminal.

[0240] The SPS parameters are carried by an RRC connection setup message (e.g., RRCConnectionSetup-NB).

[0241] The SPS parameters include SPS parameters for uplink transmission and / or SPS parameters for downlink transmission. Alternatively, the SPS parameters are applicable to both uplink transmission and downlink transmission.

[0242] The SPS parameters include an SPS resource period and an SPS scrambling code (e.g., SPS C-RNTI). The SPS resource period can be one or more SPS resource periods. Optionally, the SPS parameters further include a number of HARQ processes available for the SPS resource. It is to be noted that in the case where the number of HARQ processes available for the SPS resource is not specified, the terminal defaults N HARQ processes available. Where N is a predetermined value, for example, 1 or 2. The HARQ process ID corresponding to the default N HARQ processes can also be predetermined. For example, in the case where there is only one HARQ process available by default, the corresponding HARQ process ID is HARQ Process ID = 0. In the case where there are two HARQ processes available by default, the corresponding HARQ process IDs are HARQ Process ID = 0, 1.

[0243] Optionally, before the base station configures the SPS parameters, the terminal provides SPS assistance information (i.e., second semi-persistent resource assistance information) to the base station. The SPS assistance information is used to assist the base station in configuring the SPS parameters. The SPS assistance information can include one or more of the following (1) to (3):

[0244] (1) information indicating that the cause of RRC connection setup is voice (i.e., first indication);

[0245] Specifically, the cause of RRC connection setup can be a calling voice (mo-VoiceCall). For example, the terminal can carry an RRC connection setup cause field in the RRC connection setup request message, and the cause field is set to calling voice.

[0246] (2) information indicating that the cause of RRC connection setup is an emergency call (i.e., second indication);

[0247] For example, the terminal can carry an RRC connection setup cause field in the RRC connection setup request message, and the cause field is set to emergency call.

[0248] (3) SPS configuration request information (i.e., third indication). The SPS configuration request information is used to request the base station to configure SPS parameters.

[0249] For example, the terminal can carry the SPS configuration request information in the RRC connection establishment request message.

[0250] The SPS configuration request information (e.g., SPSConfigurationRequest) can be a one-bit indication field. For example, when the terminal carries the SPS configuration request information in the RRC connection establishment request message or the SPS configuration request information is set to “true”, the base station configures the SPS parameters for the terminal.

[0251] For example, the SPS configuration request information can be a request information common to uplink and downlink. For example, when the terminal provides the SPS configuration request information to the base station, the base station defaults that the terminal requests to configure uplink SPS resources and downlink SPS resources. The SPS configuration request information can also be a request information for uplink or downlink respectively. For example, SPSConfigurationRequest-UL is used to request to configure uplink SPS resources, and SPSConfigurationRequest-DL is used to request to configure downlink SPS resources.

[0252] Optionally, when the terminal is a called terminal, the SPS parameters are configured by default by the base station. For example, when the terminal is a called terminal, the base station triggers the terminal to establish an RRC connection through a paging mechanism. When the terminal accesses the base station, the base station configures the SPS parameters for the terminal by default.

[0253] Step 2: The terminal receives SPS activation indication information (i.e., first control signaling) sent by the base station. Based on the SPS activation indication information, the terminal stores the semi-static resources and corresponding HARQ information configured by the base station.

[0254] For example, the SPS activation indication information can include UL SPS activation indication information and / or DL SPS activation indication information.

[0255] For example, the SPS activation indication information can be carried by DCI. The DCI can be scrambled by SPS C-RNTI.

[0256] Optionally, the DCI also carries periodic information of SPS resources. For example, the periodic information of SPS resources can be any one of the following (1) to (3):

[0257] (1) SPS resource periodicity bitmap.

[0258] For example, the protocol agrees that the periodicity of SPS resource is {20ms, 40ms, 80ms}, and the SPS resource periodicity bitmap can be 3 bits, each bit corresponding to the agreed periodicity. For example, SPS resource periodicity bitmap = 010 can be used to indicate that the periodicity of SPS resource is 40ms.

[0259] (2) SPS resource periodicity. For example, SPS periodicity = 40ms.

[0260] (3) SPS index. For example, SPS index.

[0261] For example, in the case where the SPS parameter contains multiple SPS periodicities (such as SPS periodicity list), the DCI can carry SPS index, which corresponds to multiple SPS periodicities in the SPS parameter. For example, the SPS parameter contains a first SPS periodicity, SPS index = 1; the SPS parameter contains a second SPS periodicity, SPS index = 2.

[0262] It should be noted that in the case where the DCI carries SPS periodicity, the terminal considers that the SPS periodicity configured by the DCI covers the SPS periodicity configured by the RRC message.

[0263] Optionally, before the base station issues the SPS activation indication information, the base station obtains service mode information of the service. The service mode information includes service periodicity information of the service. Optionally, the service mode information further includes single-period data packet size information and data flow direction information. The SPS activation indication information is used to activate the SPS resource corresponding to the service.

[0264] The base station obtains the service mode information in the following ways:

[0265] The base station obtains the service mode information from a core network device.

[0266] The base station obtains the service mode information based on service statistics.

[0267] Step 3 (optionally): The terminal feeds back SPS confirmation information (i.e. first confirmation information) to the base station. The SPS confirmation information is used to feed back that the terminal has activated the SPS resource configured by the base station.

[0268] The SPS confirmation information is carried by a MAC CE. Optionally, the MAC CE is identified by a newly introduced logical channel identity (LCID). Optionally, the LCID is a voice service specific LCID agreed by a protocol.

[0269] Step 4 (optionally): The terminal receives SPS release indication information (i.e., second control signaling) sent by the base station. Based on the SPS release indication information, the terminal clears the semi-static resources configured by the base station.

[0270] Before sending the SPS release indication information, the base station obtains SPS release assistance information (i.e., third semi-static resource assistance information) from a core network. The SPS release assistance information includes indication information that a voice session has ended.

[0271] Step 5 (optionally): The terminal feeds back SPS confirmation information (i.e., second confirmation information) to the base station. The SPS confirmation information is used to feed back that the terminal has released the SPS resources configured by the base station.

[0272] The SPS confirmation information is carried by a MAC CE. Optionally, the MAC CE is identified by a newly introduced LCID. Optionally, the LCID is a voice service specific LCID agreed by a protocol.

[0273] Embodiment 2: Introducing RRC connection reconfiguration message for CP NB-IoT

[0274] As shown in FIG. 6, the following steps are included:

[0275] Step 1: The terminal receives SPS parameters configured by the base station. The SPS parameters are carried by an RRC connection reconfiguration message.

[0276] The terminal is a control plane narrowband Internet of Things (CP NB-IoT) terminal. Further, the terminal is an NTN terminal.

[0277] The RRC connection reconfiguration message is transmitted by SRB1bis.

[0278] The SPS parameters include SPS parameters for uplink transmission and / or SPS parameters for downlink transmission. Alternatively, the SPS parameters are applicable to both uplink transmission and downlink transmission.

[0279] The SPS parameters include an SPS resource period and an SPS scrambling code (e.g., SPS C-RNTI). Optionally, the SPS parameters further include a number of HARQ processes available for the SPS resource. It should be noted that in the case where the number of HARQ processes available for the SPS resource is not specified, the terminal defaults to N HARQ processes available. N is a predetermined value, for example, 1 or 2. The HARQ process numbers corresponding to the N HARQ processes available are also predetermined. For example, in the case where there is only one HARQ process available by default, the corresponding HARQ process number is HARQ Process ID = 0. In the case where there are two HARQ processes available by default, the corresponding HARQ process numbers are HARQ Process ID = 0, 1.

[0280] Optionally, the SPS parameters further include starting position information of the SPS resource. The starting position information of the SPS resource includes starting position information of uplink SPS resource and / or starting position information of downlink SPS resource.

[0281] Before the base station issues the SPS parameters, the base station acquires service mode information of a service, where the service mode information includes service period information of the service. The SPS parameters are used to configure SPS resources corresponding to the service. The base station acquires the service mode information in any of the following ways:

[0282] The base station acquires the service mode information from a core network.

[0283] The base station acquires the service mode information based on service flow statistics.

[0284] The base station receives the service mode information reported by the terminal.

[0285] The service mode information reported by the terminal can be a recommended SPS period. The SPS period is determined by the terminal based on service period. The terminal acquires the service period from an upper layer (e.g., NAS) of the terminal.

[0286] The service mode information reported by the terminal can be carried in an RRC message. The RRC message can be transmitted through SRB1bis.

[0287] The service mode information reported by the terminal can be carried in a MAC CE. For example, Recommended SPS periodicity MAC CE. The MAC CE is identified by a predetermined LCID.

[0288] Step 2 (optionally): The terminal receives the SPS activation indication information (i.e., first control signaling) issued by the base station. Based on the SPS activation indication information, the terminal stores the semi-static resource configured by the base station and the corresponding HARQ information.

[0289] Wherein, in the case that the SPS parameter does not include resource starting position information, the base station issues the SPS activation indication information to the terminal.

[0290] Wherein, the SPS activation indication information can be UL SPS activation indication information and / or DL SPS activation indication information.

[0291] Wherein, the SPS activation indication information is carried by DCI. The DCI is scrambled by SPS C-RNTI.

[0292] Wherein, the DCI carries the starting position information of the SPS resource.

[0293] Steps 3 to 5: Same as Embodiment 1.

[0294] Embodiment 3: UE recommends SPS period, DCI activates SPS

[0295] As shown in FIG. 7, the following steps are included:

[0296] Step 1: The terminal sends the recommended SPS parameter (i.e., first semi-static resource auxiliary information) to the base station. The SPS parameter is used to assist the base station to configure SPS resource for the terminal.

[0297] Wherein, the terminal is a control plane narrowband Internet of Things (CP NB-IoT) terminal. Further, the terminal is an NTN terminal.

[0298] Wherein, the SPS parameter includes SPS period. Exemplarily, the recommended SPS period is 40 ms. Optionally, the SPS parameter also contains the number of available HARQ processes of the SPS resource. It should be noted that in the case of default SPS resource available HARQ process number, N default recommended available HARQ processes. Wherein, N is an agreed value, for example, can be 1 or 2. The HARQ process number corresponding to the default N HARQ processes can also be a protocol agreement. For example, in the case of default only one available HARQ process, the corresponding HARQ process number HARQ Process ID = 0. In the case of default two available HARQ processes, the corresponding HARQ process number HARQ Process ID = 0, 1.

[0299] Wherein, the SPS parameter can be reported by some arbitrary way:

[0300] The SPS parameter can be carried by an RRC message. The RRC message is transmitted by SRB1bis.

[0301] The SPS parameter can be carried by a MAC CE. For example, a Recommended SPS periodicity MAC CE. The MAC CE is identified by a protocol-agreed LCID.

[0302] The MAC CE can include a period information field, which is used to indicate the recommended SPS period.

[0303] Alternatively, the MAC CE can include a bitmap. For example, the protocol agrees that the SPS resource period includes {20ms, 40ms, 80ms}, and the bitmap can be 3 bits, each bit corresponding to the agreed period. For example, the bitmap 010 can be used to indicate that the SPS period is 40ms.

[0304] Before the terminal sends the recommended SPS parameter to the base station, the terminal obtains the service period information of the service (i.e., the target service) to be carried by the SPS. For example, the terminal obtains the service period from the upper layer (e.g., NAS) of the terminal. For example, after the terminal upper layer completes the IMS voice call process, the terminal obtains the service period information based on the service information negotiated in the IMS voice call process.

[0305] Step 2 (optionally): The terminal receives the SPS activation indication information (i.e., first control signaling) issued by the base station. Based on the SPS activation indication information, the terminal stores the semi-static resource configured by the base station and the corresponding HARQ information.

[0306] In the case where the SPS parameter does not include resource start position information, the base station issues the SPS activation indication information to the terminal.
