The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0040] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0041] With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the Third Generation Partnership Project (3GPP) rd The 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0042] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0043] RRC Status

[0044] In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new RRC state, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0045] 1) RRC_IDLE state (abbreviated as idle state): Mobility is based on cell selection and reselection of terminal equipment, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no terminal equipment context on the base station side, and there is no RRC connection.

[0046] 2) RRC_CONNECTED state (referred to as connected state): There is an RRC connection, and there is a terminal device context on the base station side and the terminal device side. The network side knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal device and the base station.

[0047] 3) RRC_INACTIVE state (abbreviated as inactive state): Mobility is based on cell selection reselection of the terminal device, there is a connection between CN-NR, the terminal device context exists on a certain base station, paging is triggered by RAN, and the paging area based on RAN is managed by RAN. The network side knows the location of the terminal device based on the paging area level of RAN.

[0048] The above three RRC states can be switched to each other. The terminal device is in an inactive state. The terminal device automatically returns to the idle state in the following situations:

[0049] When the terminal device receives the paging message initiated by the CN;

[0050] When the terminal device initiates an RRC recovery request, it starts timer T319. If the timer times out;

[0051] When the terminal device fails to verify the integrity of MSG4;

[0052] When the terminal device reselects to another radio access technology (Radio Access Technology, RAT);

[0053] The terminal device enters the camp on any cell state.

[0054] When the terminal device is in an inactive state, the network side will configure the RRC inactive configuration parameters for the terminal device through an RRC release message. The RRC inactive configuration parameters mainly include:

[0055] The inactive RNTI (I-RNTI) is used to identify the inactive context of the terminal device (UE inactive context) on the base station side and is unique within the base station.

[0056] RAN Notification Area (RNA) is an area used to control the cell selection and reselection of terminal equipment in an inactive state, and is also the paging range area of ​​RAN initial paging.

[0057] RAN Paging cycle: used to calculate the paging opportunity of RAN initial paging.

[0058] RNA update period (RNAU periodicity) is used to control the period at which the terminal device performs periodic RAN location updates.

[0059] Next hop chaining counter (NCC) is used to determine the key used during RRC connection recovery.

[0060] When the terminal device moves within the RNA area, it does not need to notify the network side and follows the mobility behavior in the idle state, that is, the cell selection and reselection principle. When the terminal device moves out of the paging area configured by the RAN, the terminal device triggers the RRC connection recovery process (i.e., RRC resume procedure) and reacquires the paging area configured by the RAN. When the network side needs to transmit data to the terminal device, that is, when downlink data arrives, the base station that saves the terminal device context (that is, the base station that maintains the connection between the access network and the core network for the terminal device) triggers all cells in the RAN paging area to send a paging message to the terminal device, so that the terminal device in the inactive state can restore the RRC connection and receive data. In addition, the terminal device in the inactive state is configured with a RAN paging area. In order to ensure the reachability of the terminal device in this area, the terminal device needs to perform periodic location updates according to the period configured by the network. The scenarios that trigger the terminal device to perform RNA updates include the expiration of the RNAU timer or the movement of the terminal device to an area outside the RNA. At present, the inactive state defined by NR does not support the transmission of user plane data by the terminal device.

[0061] When the target base station for the terminal device to initiate the RRC connection recovery process is not the anchor base station, the anchor base station determines whether the context of the terminal device needs to be transferred to the target base station. Generally, the target base station will send the cause value carried in the RRC recovery request message sent by the terminal device to the anchor base station during the terminal context request process, and the anchor base station determines whether the context of the terminal device needs to be transferred to the target base station. For example, the RRC connection recovery process triggered by periodic RAN location update generally does not require context transfer.

[0062] Through the RRC connection recovery process, the terminal device can transmit small data through the user plane, that is, to achieve early data transmission (EDT) or small data transmission. Specifically, small data is transmitted in the dedicated transmission channel (DTCH), MSG3 (RRC recovery request message) is transmitted in the common control channel (CCCH), DTCH and CCCH are multiplexed and transmitted at the MAC layer, thereby achieving uplink transmission of small data. Similarly for downlink, small data is transmitted in DTCH, MSG4 (RRC release message) is transmitted in CCCH, DTCH and CCCH are multiplexed and transmitted at the MAC layer, thereby achieving downlink transmission of small data.

[0063] It should be noted that the description of "small data" in the embodiments of the present application can also be replaced by "small packet data" or "small data packet".

[0064] Although LTE supports small packet data transmission, the small packet data transmission in LTE is used in specific scenarios, such as IoT type terminals, that is, the services supported by the terminals that perform small packet data transmission are limited to IoT type services. The business data volume of such terminals themselves is small and supports small packet data transmission. However, in NR, small packet data transmission may have a wider range of applications, so the services supported by the terminals that perform small packet data transmission are no longer a single IoT type service. In order to more effectively perform small packet data transmission, a strategy for effectively controlling small packet data transmission is required. To this end, the following technical solutions of the embodiments of the present application are proposed.

[0065] Figure 2 A flow chart of a method for configuring a transmission strategy provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the configuration method of the transmission strategy includes the following steps:

[0066] Step 201: The base station receives first configuration information sent by the core network, where the first configuration information is used to determine a transmission strategy for small packet data.

[0067] In an optional embodiment of the present application, the base station is a gNB.

[0068] In an optional manner of the present application, the first configuration information is configured by a session management function network element (Session Management Function, SMF) in the core network. The base station receives the first configuration information sent by an access management function network element (Access and Mobility Management Function, AMF) in the core network, wherein the first configuration information is sent by the SMF to the AMF. Specifically, the SMF configures the first configuration information and sends the first configuration information to the AMF, and the AMF then sends the first configuration information to the base station. Optionally, the first configuration information is transparent to the AMF, that is, after receiving the first configuration information from the SMF, the AMF does not parse the first configuration information, and directly transmits the first configuration information to the base station.

[0069] In an optional manner of the present application, the first configuration information is carried in one of the following messages:

[0070] PDU SESSION RESOURCE SETUP REQUEST message;

[0071] Initial context setup request (INITIAL CONTEXT SETUP REQUEST) message;

[0072] Handover request (HANDOVER REQUEST) message;

[0073] Path SWITCH REQUEST ACKNOWLEDGE message.

[0074] That is to say, the AMF transmits the first configuration information to the base station through one of the above messages.

[0075] In an optional manner of the present application, the base station also receives the QoS parameters sent by the AMF. Here, optionally, the QoS parameters are configured by the AMF. That is, the base station receives the QoS parameters configured by the AMF and the first configuration information configured by the SMF sent by the AMF.

[0076] In the embodiment of the present application, the first configuration information is used to determine the transmission strategy of the small packet data (which may also be referred to as the small packet data transmission strategy). Here, the first configuration information may also be directly referred to as the small packet data transmission strategy. It should be noted that the following description of the first configuration information may also be understood as a description of the small packet data transmission strategy.

[0077] ●In an optional manner, the first configuration information includes first requirement information for packet data transmission (hereinafter referred to as the first requirement information), wherein the first requirement information is: supporting packet data transmission, or not supporting packet data transmission, or tending to support packet data transmission. It should be noted that the description of "support" in the embodiment of the present application can also be replaced by "allow" or "allow to use" or "use". The description of "not support" in the embodiment of the present application can also be replaced by "not allowed" or "not allowed to use" or "not use".

[0078] A) In an optional manner, the first configuration information includes at least one first requirement information, wherein each first requirement information in the at least one first requirement information is associated with an identifier of a PDU session.

[0079] Specifically, the first requirement information may be configured with a PDU session as the granularity (per PDU session), that is, each first requirement information is associated with a PDU session identifier (PDU session id). Here, a PDU session identifier represents an identifier of a PDU session, and is used to indicate a PDU session.

[0080] If the first requirement information supports small packet data transmission or tends to support small packet data transmission, a PDU session associated with the first requirement information can use the small packet data transmission process;

[0081] If the first requirement information does not support small packet data transmission, a PDU session associated with the first requirement information cannot use the small packet data transmission process.

[0082] It should be noted that the contents of the first demand information associated with different PDU sessions are independent of each other and may be the same or different.

[0083] B) In an optional manner, the first configuration information includes at least one first requirement information, wherein each first requirement information in the at least one first requirement information is associated with a quality of service flow (Qos flow) identifier or a group of Qos flow identifiers.

[0084] Specifically, the first demand information may be configured at a granularity of Qos flow (per Qos flow), that is, each first demand information is associated with a Qos flow identifier (Qos flow id). Alternatively, the first demand information may be configured at a granularity of Qos flow list (per Qos flow list), that is, each first demand information is associated with a group of Qos flow identifiers.

[0085] If the first requirement information supports small packet data transmission or tends to support small packet data transmission, a QoS flow or a group of QoS flows associated with the first requirement information can use the small packet data transmission process;

[0086] If the first requirement information does not support small packet data transmission, then a QoS flow or a group of QoS flows associated with the first requirement information cannot use the small packet data transmission process.

[0087] It should be noted that the contents of the first requirement information associated with different QoS flows or QoS flow lists are independent of each other and may be the same or different.

[0088] C) In an optional manner, the first configuration information includes at least one first requirement information, wherein each first requirement information in the at least one first requirement information is associated with a terminal device.

[0089] Specifically, the first requirement information may be configured based on the granularity of a terminal device (per UE), that is, each first requirement information is associated with an identifier of a terminal device.

[0090] If the first requirement information supports small packet data transmission or tends to support small packet data transmission, all services under a terminal device associated with the first requirement information can use the small packet data transmission process;

[0091] If the first requirement information does not support small packet data transmission, all services under a terminal device associated with the first requirement information cannot use the small packet data transmission process.

[0092] It should be noted that the contents of the first demand information associated with different terminal devices are independent of each other and can be the same or different.

[0093] ●In an optional manner, the first configuration information includes second requirement information, wherein the second requirement information includes at least one of the following:

[0094] The QoS flow that meets the first condition can use the small packet data transmission process;

[0095] A PDU session that meets the second condition can use the packet data transmission process.

[0096] Here, the Qos flow that meets the first condition can use the small packet data transmission process, which means that the Qos flow whose Qos parameters meet the specified threshold can use the small packet data transmission process.

[0097] Here, the PDU session that meets the second condition can use the small packet data transmission process, which means that the PDU session whose specific parameters meet the specified threshold can use the small packet data transmission process.

[0098] I) In an optional manner, when the rate parameter of a Qos flow is lower than a specified threshold, the Qos flow can use a small packet data transmission process.

[0099] Here, the specified threshold is a threshold configured on the network side, or a threshold agreed upon by a protocol, or a pre-configured threshold.

[0100] Optionally, the rate parameter of the Qos flow is lower than a specified threshold, including: the uplink rate parameter of the Qos flow is lower than a first threshold; and / or, the downlink rate parameter of the Qos flow is lower than the first threshold. Here, the uplink and downlink can be configured with a unified threshold, that is, both the uplink rate parameter and the downlink rate parameter are compared with the first threshold.

[0101] Optionally, the rate parameter of the QoS flow is lower than a specified threshold, including: the uplink rate parameter of the QoS flow is lower than a first threshold; and / or, the downlink rate parameter of the QoS flow is lower than a second threshold.

[0102] In specific implementation, the uplink rate parameter is: Maximum Flow Bit Rate Uplink, or Guaranteed Flow Bit Rate Uplink; the downlink rate parameter is: Maximum Flow Bit Rate Downlink, or Guaranteed Flow Bit Rate Downlink. The information of these QoS parameters is shown in Table 1 below.

[0103]

[0104] Table 1

[0105] II) In an optional manner, when the packet delay budget of a QoS flow is lower than a specified threshold, the QoS flow can use a small packet data transmission process.

It should be noted that the smaller the priority value, the higher the priority.

[0111] Here, the designated priority value or the designated priority is configured on the network side, or agreed upon by the protocol, or pre-configured.

[0112] Here, the priority information can be referred to as shown in Table 3 below.

[0113]

[0114] Table 3

[0115] IV) In an optional manner, when the aggregate maximum bit rate (AMBR) of a PDU session is lower than a specified threshold, the PDU session can use the packet data transmission process.

[0116] Here, the specified threshold is a threshold configured on the network side, or a threshold agreed upon by a protocol, or a pre-configured threshold.

[0117] Optionally, the AMBR of the PDU session is lower than a specified threshold, including: the uplink AMBR of the PDU session is lower than a third threshold; or the downlink AMBR of the PDU session is lower than the third threshold.

The AMBR information can be referred to as shown in Table 4 below.

[0119]

[0120] Table 4

[0121] It should be noted that the above-mentioned first requirement information and the second requirement information can be implemented independently or in combination. When the above-mentioned first requirement information and the second requirement information are implemented in combination, when it is determined according to the first requirement information that a PDU session or a Qos flow or a Qos flow list can perform a small packet data transmission process, it is necessary to further determine according to the second requirement information whether the PDU session or the Qos flow or the Qos flow in the Qos flow list can perform a small packet data transmission process.

[0122] Step 202: The base station sends first indication information to the terminal device based on the first configuration information, wherein the first indication information is used to indicate whether to execute a packet data transmission process.

[0123] Correspondingly, the terminal device receives the first indication information sent by the base station, wherein the first indication information is used to indicate whether to execute the packet data transmission process, and the first indication information is determined based on the first configuration information, and the first configuration information is used to determine the transmission strategy of the packet data.

[0124] In an embodiment of the present application, the base station configures an indication information (i.e., the first indication information) to the terminal device based on the first configuration information, with a data radio bearer (Data Resource Bearer, DRB) as the granularity (per DRB) or a PDU session as the granularity (per PDU session), and the indication information is used to indicate whether to execute the packet data transmission process.

[0125] Specifically, the base station sends first indication information associated with each DRB in at least one DRB to the terminal device; or, the base station sends first indication information associated with each PDU session in at least one PDU session to the terminal device. Correspondingly, the terminal device receives first indication information associated with each DRB in at least one DRB sent by the base station; or, first indication information associated with each PDU session in at least one PDU session. The first indication information is used to indicate whether to execute the packet data transmission process.

[0126] In the embodiment of the present application, the first indication information may be a unified indication for uplink and downlink, that is, the first indication information is used to indicate whether to execute the uplink and downlink packet data transmission process. Alternatively, the first indication information may be an independent indication for uplink and downlink, that is: the first indication information is used to indicate whether to execute the uplink packet data transmission process; or, the first indication information is used to indicate whether to execute the downlink packet data transmission process.

[0127] Through the above-mentioned technical scheme of the embodiment of the present application, the core network configures the transmission strategy of the small packet data, and sends the transmission strategy of the small packet data to the base station through the first configuration information. The base station sends an indication information of whether to execute the small packet data transmission process to the terminal device based on the first configuration information, so that the terminal device can execute the small packet data transmission more effectively.

[0128] On the other hand, the embodiment of the present application also proposes a solution for controlling the effectiveness of the packet data transmission strategy, which is described below.

[0129] In an optional manner of the present application, the base station sends at least one of the following to the terminal device, and the terminal device receives at least one of the following sent by the base station:

[0130] second indication information, where the second indication information is used to indicate a valid area range of the first indication information, wherein the first indication information is valid within the valid area range;

[0131] third indication information, where the third indication information is used to indicate a valid time range of the first indication information;

[0132] Fourth indication information, where the fourth indication information is used to indicate a valid number threshold of the first indication information.

[0133] In the above scheme, the second indication information is used to indicate the effective area range of the first indication information. Further, optionally, the effective area range is: a physical cell identifier (PCI) list, or a cell identifier list, or a tracking area (TA) list, or a radio access network code (RAN code) list, or a public land mobile network (PLMN) list. Here, the packet data transmission strategy has the characteristics of regional control, that is, after the base station sends the first indication information, it will also send the effective area range of the first indication information. The first indication information is valid only when and only when the terminal device is within the effective area range (that is, the content indicated by the first indication information is valid).

[0134] In the above scheme, the third indication information is used to indicate the effective time range of the first indication information. Further, optionally, the third indication information includes the configuration information of the first timer. After the third indication information is received by the terminal device, the terminal device starts the first timer. If the first timer times out, the first indication information becomes invalid. Here, the packet data transmission strategy has the characteristics of timeliness control, that is, after the base station sends the first indication information, it also sends the effective time information of the first indication information (that is, the configuration information of the first timer). When the terminal device receives the configuration information of the first timer, it starts the first timer. If the first timer times out, the first indication information previously configured by the terminal device becomes invalid (that is, the content indicated by the first indication information becomes invalid).

[0135] In the above scheme, the fourth indication information is used to indicate the effective number threshold of the first indication information. Further, optionally, the fourth indication information includes the configuration information of the first counter. After the fourth indication information is received by the terminal device, the terminal device resets the first counter. Each time the terminal device performs a small packet data transmission, the value of the first counter is increased by 1. If the value of the first counter is greater than or equal to the maximum value, the first indication information is invalid. Here, the effective number threshold of the first indication information is the maximum value of the first counter. For downlink pre-configured resources, the small packet data transmission strategy has the characteristics of counting restrictions, that is, after the base station sends the first indication information, it will also send the effective number threshold of the first indication information (that is, the configuration information of the first counter). When the terminal device receives the configuration information of the first counter, it resets the first counter to 0. Each time the terminal device performs a small packet data transmission, the first counter is increased by 1. If the first counter is greater than or greater than or equal to the maximum value, the first indication information previously configured by the terminal device is invalid (that is, the content indicated by the first indication information is invalid).

[0136] In the above scheme, at least one of the second indication information, the third indication information and the fourth indication information is configured by the base station; or, at least one of the second indication information, the third indication information and the fourth indication information is configured by the SMF and sent to the base station via the AMF; or, at least one of the second indication information, the third indication information and the fourth indication information is configured by the AMF and sent to the base station.

[0137] It should be noted that at least one of the second indication information, the third indication information and the fourth indication information may not be sent to the terminal device together with the first indication information. For example, the base station separately sends at least one of the second indication information, the third indication information and the fourth indication information to the terminal device.
