In order 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.
With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3) rd Generation Partnership Project,3 GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (mMTC).
On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.
5G, in order to reduce air interface signaling, quickly recover radio connection, and quickly recover data service, a new RRC state, that is, an RRC INACTIVE (RRC _ INACTIVE) state, is defined. This state is distinguished from the RRC IDLE (RRC IDLE) state and the RRC ACTIVE (RRC ACTIVE) state. Wherein,
1) RRC _ IDLE state (IDLE state for short): the mobility is cell selection and reselection based on terminal equipment, paging is initiated by a Core Network (CN), and a paging area is configured by the CN. The base station side has no terminal equipment context and no RRC connection.
2) RRC _ CONNECTED state (CONNECTED state for short): the RRC connection exists, and the base station side and the terminal device side have a terminal device context. The network side knows that the location of the terminal device is at a particular cell level. Mobility is network side controlled mobility. Unicast data may be transmitted between the terminal device and the base station.
3) RRC _ INACTIVE state (INACTIVE state for short): mobility is based on cell selection reselection of terminal equipment, connection between CN-NR exists, context of the terminal equipment exists on a certain base station, paging is triggered by RAN, a paging area based on the RAN is managed by the RAN, and the network side knows that the position of the terminal equipment is based on the paging area level of the RAN.
The three RRC states can be switched with each other. The terminal equipment is in an inactive state, and the terminal equipment automatically returns to an idle state under the following conditions:
when the terminal equipment receives a paging message initiated by a CN;
when the terminal equipment initiates an RRC recovery request, a timer T319 is started, and if the timer is overtime;
when the terminal equipment fails to verify the integrity protection of the MSG 4;
when the terminal equipment cell reselects to other Radio Access Technology (RAT);
the terminal equipment enters a camp on any cell (camp on any cell) state.
When the terminal device is in an inactive state, the network side configures an RRC inactive configuration parameter to the terminal device through an RRC release message, where the RRC inactive configuration parameter mainly includes:
an inactive RNTI (I-RNTI) for identifying a terminal device inactive context (UE inactive context) of the terminal device on the base station side, which is unique within the base station.
A RAN Notification Area (RNA), which is an Area for controlling the terminal device to perform cell selection reselection in an inactive state, is also a paging Area for RAN initial paging.
A RAN Paging cycle (RAN Paging cycle) used to calculate a Paging occasion for RAN initial Paging.
An RNA update period (RNAU periodicity) for controlling a period for the terminal device to perform periodic RAN location updates.
Next hop Chaining Counter (NCC) for determining keys used in the RRC connection recovery procedure.
When the terminal device moves in the RNA area, the network side is not informed, and the mobility behavior in an idle state, namely the cell selection and reselection principle, is followed. When the terminal device moves out of the paging area configured by the RAN, the terminal device triggers the recovery of the RRC connection procedure (i.e., RRC resume procedure) and reacquires the paging area configured by the RAN. When a network side needs to transmit data to the terminal device, that is, when downlink data arrives, a base station storing the context of the terminal device (that is, a base station maintaining connection between an access network and a core network for the terminal device) triggers all cells in a RAN paging area to send paging messages to the terminal device, so that the terminal device in an inactive state can recover RRC connection and receive data. In addition, the terminal device in the inactive state configures a RAN paging area, and in order to ensure the reachability of the terminal device in the area, the terminal device needs to perform periodic location update according to a period configured by the network. Scenes that trigger the terminal device to perform RNA updates have the RNAU timer expired or the terminal device moved to an area outside the RNA. Currently, the inactive state defined by NR does not support the terminal device to transmit user plane data.
When the target base station of the RRC connection recovery process initiated by the terminal equipment is not the anchor base station, the anchor base station judges whether the context of the terminal equipment needs to be transferred to the target base station side. Generally, the target base station sends 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, and the anchor base station determines whether the context of the terminal device needs to be transferred to the target base station. RRC connection recovery procedures such as periodic RAN location update triggers typically do not require context transfer.
Through the RRC connection recovery procedure, the terminal device may transmit small Data through the user plane, that is, early Data Transmission (EDT) or small Data Transmission is implemented. Specifically, the small data is transmitted in a Dedicated Transmission Channel (DTCH), the MSG3 (i.e., RRC recovery request message) is transmitted in a Common Control Channel (CCCH), and the DTCH and the CCCH are multiplexed and transmitted in the MAC layer, thereby implementing uplink Transmission of the small data. In the same downlink manner, the small data is transmitted in the DTCH, the MSG4 (i.e. the RRC release message) is transmitted in the CCCH, and the DTCH and the CCCH are multiplexed and transmitted in the MAC layer, thereby realizing the downlink transmission of the small data.
It should be noted that the description of the "small data" in the embodiments of the present application may also be replaced by "small packet data" or "small data packet".
Although LTE supports packet data transmission, the packet data transmission in LTE is used in a specific scenario, for example, a terminal of an internet of things type, that is, a service supported by a terminal that performs packet data transmission is limited to an internet of things type service, and such a terminal has a small service data volume and supports packet data transmission. However, in NR, packet data transmission may be more widely applied, so that a service supported by a terminal performing packet data transmission is no longer a single internet of things type service, and a policy for effectively controlling packet data transmission is required in order to more effectively perform packet data transmission. Therefore, the following technical scheme of the embodiment of the application is provided.
Fig. 2 is a schematic flowchart of a configuration method of a transmission policy provided in an embodiment of the present application, and as shown in fig. 2, the configuration method of the transmission policy includes the following steps:
step 201: the base station receives first configuration information sent by a core network, wherein the first configuration information is used for determining a transmission strategy of packet data.
In an optional manner of this application, the base station is a gbb.
In an optional manner of this application, the first configuration information is configured by a Session Management Function (SMF) element in a core network. The base station receives first configuration information sent by an Access Management Function network element (AMF) in a core network, wherein the first configuration information is sent to the AMF by the SMF. Specifically, the SMF configures first configuration information and sends the first configuration information to the AMF, and the AMF 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 directly passes the first configuration information to the base station without analyzing the first configuration information.
In an optional manner of this application, the first configuration information is carried in one of the following messages:
a PDU Session RESOURCE SETUP REQUEST (PDU Session response SETUP REQUEST) message;
an INITIAL CONTEXT SETUP REQUEST (INITIAL CONTEXT SETUP REQUEST) message;

a path selection REQUEST ACKNOWLEDGE (PATH SWITCH REQUEST ACKNOWLEDGE) message.
That is, the AMF delivers the first configuration information to the base station through the above one message.
In an optional manner of this application, the base station further receives a Qos parameter sent by the AMF. Here, optionally, the Qos parameter is configured by the AMF. That is, the base station receives the Qos parameter configured by the AMF and the first configuration information configured by the SMF, which are transmitted by the AMF.
In this embodiment of the present application, the first configuration information is used to determine a transmission policy of packet data (which may also be referred to as a packet data transmission policy for short).

if the first requirement information does not support the packet data transmission, all services under a terminal device associated with the first requirement information cannot use the packet data transmission process.

It should be noted that the first requirement information and the second requirement information may be implemented independently or may be implemented in combination. When the first requirement information and the second requirement information are implemented together, in a case that it is determined that the PDU session or the Qos flow list can execute the packet data transmission process according to the first requirement information, it is further required to determine whether the Qos flow in the PDU session or the Qos flow list can execute the packet data transmission process according to the second requirement information.
Step 202: and the base station sends first indication information to the terminal equipment based on the first configuration information, wherein the first indication information is used for indicating whether to execute a packet data transmission process.
Correspondingly, the terminal equipment receives first indication information sent by the base station, wherein the first indication information is used for indicating whether a packet data transmission process is executed or not, the first indication information is determined based on first configuration information, and the first configuration information is used for determining a transmission strategy of packet data.
In this embodiment of the present application, based on the first configuration information, the base station configures, to the terminal device, indication information (i.e., first indication information) by using a Data Radio Bearer (DRB) as a granularity (per DRB) or by using a PDU session as a granularity (per PDU session), where the indication information is used to indicate whether to execute a packet Data transmission process.
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 equipment. Correspondingly, the terminal equipment receives first indication information related to each DRB in at least one DRB sent by a base station; or, the first indication information associated with each PDU session in at least one PDU session. Wherein the first indication information is used for indicating whether to execute a packet data transmission process.
In this embodiment of the application, the first indication information may indicate uplink and downlink uniformly, that is, the first indication information is used to indicate whether to execute an uplink and downlink packet data transmission process. Alternatively, the first indication information may be independently indicated for uplink and downlink, that is: the first indication information is used for indicating whether to execute an uplink packet data transmission process; or, the first indication information is used to indicate whether to execute a downlink packet data transmission process.
According to the technical scheme of the embodiment of the application, the core network configures the transmission strategy of the packet data, the transmission strategy of the packet data is issued to the base station through the first configuration information, and the base station sends the indication information whether to execute the packet data transmission process to the terminal equipment based on the first configuration information, so that the terminal equipment can execute the packet data transmission more effectively.
On the other hand, the embodiment of the present application also proposes a scheme for controlling the validity of a packet data transmission policy, and the following description is provided.
In an optional manner of this application, the base station sends, to the terminal device, at least one of the following, and the terminal device receives, from the base station, at least one of the following:
second indication information, the second indication information being used for indicating a valid area range of the first indication information, wherein the first indication information is valid in the valid area range;
third indication information, wherein the third indication information is used for indicating a valid time range of the first indication information;
fourth indication information, where the fourth indication information is used to indicate a threshold of valid times of the first indication information.
In the foregoing solution, the second indication information is used to indicate an effective area range of the first indication information. Further, optionally, the effective area range is: a Physical Cell Identity (PCI) list, a Cell identity (Cell ID) list, a Tracking Area (TA) list, a radio access Network code (RAN code) list, or a Public Land Mobile Network (PLMN) list. Here, the packet data transmission policy has a characteristic of regional control, that is, after the base station issues the first indication information, the base station also issues an effective area range of the first indication information, and if and only if the terminal device is in the effective area range, the first indication information is valid (i.e., the content indicated by the first indication information is valid).
In the foregoing solution, the third indication information is used to indicate a valid time range of the first indication information. Further, optionally, the third indication information includes configuration information of a first timer, after the third indication information is received by the terminal device, the terminal device starts the first timer, and if the first timer is overtime, the first indication information is invalid. Here, the packet data transmission policy has a characteristic of time-efficient control, that is, after the base station issues the first indication information, it also issues valid time information of the first indication information (i.e., configuration information of the first timer), when the terminal device receives the configuration information of the first timer, the first timer is started, and if the first timer is overtime, the first indication information configured before the terminal device is invalid (i.e., the content indicated by the first indication information is invalid).
In the foregoing solution, the fourth indication information is used to indicate an effective time threshold of the first indication information. Further, optionally, the fourth indication information includes configuration information of a first counter, after the fourth indication information is received by the terminal device, the terminal device resets the first counter, the terminal device adds 1 to the value of the first counter every time the terminal device executes packet data transmission, and if the value of the first counter is greater than or equal to the maximum value, the first indication information is invalid. Here, the threshold of the valid times of the first indication information is a maximum value of the first counter. For the downlink pre-configured resource, the packet data transmission policy has a feature of count limitation, that is, after the base station issues the first indication information, the base station also issues an effective time threshold of the first indication information (i.e., configuration information of the first counter), when the terminal device receives the configuration information of the first counter, the first counter is reset to 0, when the terminal device performs packet data transmission once, the first counter is incremented by 1, and if the first counter is greater than or equal to the maximum value, the previously configured first indication information of the terminal device is invalid (i.e., the content indicated by the first indication information is invalid).
In the foregoing solution, 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 an SMF and sent to the base station by 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.
It should be noted that at least one of the second indication information, the third indication information, and the fourth indication information may also be issued to the terminal device without being issued together with the first indication information, for example, the base station individually issues at least one of the second indication information, the third indication information, and the fourth indication information to the terminal device.
