目前支持的状态跃迁的流程为：The current state of the supported state transitions is:

从IDLE到CONNECTED状态，终端需要进行接入或者重建过程。从CONNECTED状态，可以通过释放过程进入到IDLE状态。From the IDLE to the CONNECTED state, the terminal needs to perform an access or rebuild process. From the CONNECTED state, the IDLE state can be entered through the release process.

现有终端状态中，除了RRC连接态分配了终端空口传输唯一标识C-RNTI和建立了相应DRB(Data Radio Bearer，数据无线承载)可以直接进行数据收发，其他状态有上行数据需要传输时，终端都要先发起连接建立，进入RRC连接态，建立RRC连接，建立DRB，才能进行后续的数据传输。In the existing terminal state, in addition to the RRC connection state, the terminal air interface transmits the unique identifier C-RNTI and the corresponding DRB (Data Radio Bearer) can directly perform data transmission and reception. When other states have uplink data to be transmitted, the terminal It is necessary to initiate connection establishment, enter the RRC connection state, establish an RRC connection, and establish a DRB for subsequent data transmission.

现有终端状态中，除了RRC连接态分配了终端空口传输唯一标识C-RNTI可以直接进行数据收发，其他状态有数据需要传输时，终端都要先进入RRC连接态，建立RRC连接，获取用于数据传输的终端空口传输唯一标识，如C-RNTI，才能进行后续的数据传输。In the existing terminal state, in addition to the RRC connection state, the terminal air interface transmission unique identifier C-RNTI can be directly used for data transmission and reception. When other states have data to be transmitted, the terminal must first enter the RRC connection state, establish an RRC connection, and obtain the RRC connection. The terminal air interface of the data transmission transmits a unique identifier, such as C-RNTI, for subsequent data transmission.

换言之，现有技术的不足也在于：只有在进入RRC连接态，建立RRC连接后，才能进行数据传输。In other words, the shortcoming of the prior art is that data transmission can be performed only after entering the RRC connected state and establishing an RRC connection.

detailed description

发明人在发明过程中注意到：The inventor noticed during the invention:

但还存在其他一些特殊状态如下：But there are other special states as follows:

新引入的终端状态：不活跃的连接态(inactive state)，在该状态下允许如下的行为：Newly introduced terminal state: Inactive state, in which the following behavior is allowed:

-核心网看该UE处于连接状态；- the core network sees that the UE is in a connected state;

-移动性是UE执行的，在网络侧预配置的RAN跟踪区域内，通过小区重选来执行，而不是切换过程进行；- mobility is performed by the UE, and is performed by cell reselection in the RAN tracking area preconfigured on the network side, instead of the handover process;

-终端被分配了在网络侧预配置的RAN跟踪区域内的唯一用户标识。- The terminal is assigned a unique user identity within the RAN tracking area preconfigured on the network side.

Inactive状态下，网络侧为终端分配一定区域内有效的RAN标识，该标识用于在inactive态下识别终端，可以用于网络侧查找终端或终端主动发起上行接入时用该标识作为身份识别进入连接态。可以称为inactive UE ID，也可以称为resume UE ID。该标识不同于全球唯一的国际移动用户标识码(International Mobile Subscriber Identity，IMSI)或连接态终端标识C-RNTI，该标识长度介于两者之间(例如inactive UE ID长度为40bit，C-RNTI长度为16bit)，只在包含多个小区或多个eNB的一定区域内有效，如果超过该区域，终端需要更新inactive UE ID。In the inactive state, the network side allocates a valid RAN identifier in a certain area for the terminal, and the identifier is used to identify the terminal in the inactive state, and can be used for the network side to find the terminal or the terminal actively initiates the uplink access, and uses the identifier as the identity entry. Connection state. It can be called an inactive UE ID, which can also be called a resume UE ID. This logo is different The globally unique International Mobile Subscriber Identity (IMSI) or the connected terminal identifier C-RNTI, the identifier length is between the two (for example, the length of the inactive UE ID is 40 bits, and the length of the C-RNTI is 16 bits). It is valid only in a certain area including multiple cells or multiple eNBs. If the area is exceeded, the terminal needs to update the inactive UE ID.

现有终端状态中，除了RRC连接态分配了终端空口传输唯一标识C-RNTI和建立了相应DRB可以直接进行数据收发，其他状态有上行数据需要传输时，终端都要先发起连接建立，进入RRC连接态，建立RRC连接，建立DRB，才能进行后续的数据传输。In the existing terminal state, in addition to the RRC connection state, the terminal air interface transmits the unique identifier C-RNTI and the corresponding DRB can be directly used for data transmission and reception. When other states have uplink data to be transmitted, the terminal must first initiate connection establishment and enter the RRC. The connection state establishes an RRC connection and establishes a DRB for subsequent data transmission.

然而，随着无线通信系统的发展，终端类型和业务类型多样化，终端省电、节约网络资源和满足各种业务类型的需求并存。例如上述，为了同时保证终端省电和快速数据传输，引入一种终端状态inactive态，这种状态下终端保持核心网连接，但不进行空口连接态的常规操作(如切换、上行定时更新、无线链路监控等)，不分配直接用于空口传输的终端标识(如C-RNTI)，因此按上述先进入RRC连接态、建立RRC连接，获取标识、进行后续数据传输的流程则不能直接进行空口调度传输。However, with the development of wireless communication systems, terminal types and service types are diversified, and terminals save power, save network resources, and meet the needs of various service types. For example, in order to ensure terminal power saving and fast data transmission at the same time, a terminal state inactive state is introduced. In this state, the terminal maintains the core network connection, but does not perform normal operations of the air interface connection state (such as handover, uplink timing update, and wireless Link monitoring, etc., does not allocate a terminal identifier (such as C-RNTI) that is directly used for air interface transmission. Therefore, the process of first entering the RRC connection state and establishing an RRC connection according to the above, obtaining the identifier, and performing subsequent data transmission cannot directly perform the air interface. Schedule transmission.

可见，上述先进入RRC连接态、建立RRC连接，获取标识、进行后续数据传输的流程过程不利于有数据到达时的快速传输，且如果只有突发小数据包需要发送，如典型机器类通信(Machine Type Communication，MTC)业务，终端进入连接态发了一个小数据包后为了省电又要进入idle或inactive态，这种状态跃迁会造成信令开销，如果终端数量巨大时(如mMTC，massive MTC场景)，这种信令开销几乎不可接受。It can be seen that the above process of first entering the RRC connection state, establishing an RRC connection, acquiring an identifier, and performing subsequent data transmission is not conducive to fast transmission when data arrives, and if only small packets need to be sent, such as typical machine type communication ( Machine Type Communication (MTC) service, the terminal enters the connection state and sends a small data packet to save power and enter the idle or inactive state. This state transition will cause signaling overhead. If the number of terminals is huge (such as mMTC, massive) MTC scenario), this signaling overhead is almost unacceptable.

基于此，本申请实施例中将解决如何在inactive态下进行快速数据传输。下面结合附图对本申请的具体实施方式进行说明。Based on this, in the embodiment of the present application, how to perform fast data transmission in an inactive state will be solved. The specific embodiments of the present application will be described below with reference to the accompanying drawings.

在说明过程中，将分别从UE与UE的当前服务的基站侧、UE的锚点基站侧的实施进行说明，然后还将给出三者配合实施的实例以更好地理解本申请实施例中给出的方案的实施。这样的说明方式并不意味着三者必须配合实施、或者必须单独实施，实际上，当UE与UE的当前服务的基站侧、UE的锚点基站侧分开实施时，其也各自解决UE侧、UE的当前服务的基站侧、UE的锚点基站侧的问题，而三者结合使用时，会获得更好的技术效果。In the description, the implementation of the current base station side of the UE and the UE's anchor base station side will be described separately, and then an example of the three implementations will be given to better understand the embodiment of the present application. The implementation of the given scheme. The description of the method does not mean that the three must cooperate with the implementation, or must be implemented separately. In fact, when the UE is separately implemented from the base station side of the current serving and the anchor base station side of the UE, the UE also resolves the UE side. The problem of the base station side of the current serving of the UE and the anchor base station side of the UE, and when the three are used in combination, a better technical effect is obtained.

在本申请实施例中，对于处于非激活状态的UE，当该UE有上下行数据要发送时，UE与当前服务基站之间采用恢复或者配置特定无线承载来传输数据，当前服务基站需要与存储UE上下文的锚点基站进行信息交互，以便于UE信息的获取和更新。In the embodiment of the present application, for the UE in the inactive state, when the UE has uplink and downlink data to be transmitted, the UE and the current serving base station use the recovery or configure the specific radio bearer to transmit data, and the current serving base station needs to be stored. The anchor base station of the UE context performs information exchange to facilitate acquisition and update of UE information.

其中特定的无线承载可以包括：数据无线承载与信令无线承载，其中，具体实施例中数据无线承载将以DRB为例进行说明，信令无线承载将以SRB1、SRB2为例进行说明，也即以下承载：The specific radio bearer may include: a data radio bearer and a signaling radio bearer. In the specific embodiment, the data radio bearer will be described by taking the DRB as an example, and the signaling radio bearer will be described by taking SRB1 and SRB2 as an example. That is, the following bearers:

1、默认DRB；1, the default DRB;

2、UE传输业务所对应的原始DRB；2. The original DRB corresponding to the UE transmission service;

3、NAS信令的SRB2(SRB：Signal Radio Bear，信令无线承载)或者默认SRBj；3. SRB2 (SRB: Signal Radio Bear) or default SRBj for NAS signaling;

4、RRC信令的SRB1或者默认SRBi；4. SRB1 of RRC signaling or default SRBi;

其中，i、j下标仅是用于标识不同的SRB1与SRB2，SRBj依然是SRB2中的一个无线承载，SRBi依然是SRB1中的一个无线承载。The subscripts of i and j are only used to identify different SRB1 and SRB2. SRBj is still a radio bearer in SRB2, and SRBi is still a radio bearer in SRB1.

实施中存在两种性质的无线承载，一种是新建立的，为方便表述，称为默认的无线承载时，也即指按预设配置建立的无线承载；另一种是之前在基站与UE之间可能保留的，也即UE保留的无线承载。There are two types of radio bearers in the implementation. One is newly established. For convenience of description, when it is called the default radio bearer, it refers to the radio bearer established according to the preset configuration. The other is the base station and the UE. The radio bearers that may be reserved between the UEs.

在说明过程中，将分别说明UE至核心网的上行数据传输以及核心网至UE的下行数据传输，并将以实例进行具体实施说明，同时，在用实例进行说明时，将按默认的按预设配置建立的DRB、保留的DRB、SRB2、SRB1的分类进行说明。In the description process, the uplink data transmission from the UE to the core network and the downlink data transmission from the core network to the UE will be respectively described, and the specific implementation will be described by way of example. At the same time, when the example is used, the default is The classification of the established DRB, reserved DRB, SRB2, and SRB1 is described.

下面首先对本申请实施例提供的技术方案的实施环境无线接入网(Radio Access Network，RAN)侧架构进行简单说明。具体是对两种在未来移动通信中可能采用的网络部署结构进行说明。The implementation of the environment access radio access network (RAN) side architecture of the technical solution provided by the embodiment of the present application is briefly described below. Specifically, it describes two network deployment structures that may be adopted in future mobile communications.

图1为网络部署结构一示意图，如图所示，图中的架构为：基站+终端，是典型的LTE架构。eNB下有多个小区(cell)，连接态下终端UE与小区进行空口数据收发，连接态UE分配有小区内唯一的UE标识C-RNTI。FIG. 1 is a schematic diagram of a network deployment structure. As shown in the figure, the architecture in the figure is: a base station + a terminal, which is a typical LTE architecture. There are multiple cells in the eNB. In the connected state, the terminal UE and the cell perform air interface data transmission and reception, and the connected UE allocates a unique UE identifier C-RNTI in the cell.

图2为网络部署结构二示意图，如图所示，图中的架构为：网络侧节点分为中央单元(Central Unit，CU)和分布式单元(Distributed Unit，DU)，用户侧节点为终端。2 is a schematic diagram of a network deployment structure. As shown in the figure, the architecture in the figure is: a network side node is divided into a central unit (CU) and a distributed unit (DU), and a user side node is a terminal.

图2是未来移动通信5G可能采用的一种架构，网络侧节点包括中央单元和分布式单元，一个中央单元控制一定区域内部署的多个分布式单元，这些分布式单元具体通过传输点发送和接收节点(Transmission Reception Point，TRP)与终端进行空口传输。一个或多个传输点可以同时为终端服务，进行数据传输，不管采用哪种方式，都需要通过网络侧为终端分配的终端空口唯一标识来进行数据调度和传输，这个标识可以是C-RNTI或TRP-RNTI。FIG. 2 is an architecture that may be adopted by the mobile communication 5G in the future. The network side node includes a central unit and a distributed unit, and one central unit controls a plurality of distributed units deployed in a certain area, and the distributed units are specifically sent through the transmission point. The receiving station (Transmission Reception Point, TRP) and the terminal perform air interface transmission. One or more transmission points can simultaneously serve the terminal for data transmission. Regardless of the method, the data is scheduled and transmitted through the unique identifier of the terminal air interface allocated by the network side for the terminal. The identifier may be C-RNTI or TRP-RNTI.

本申请实施例中提供的技术方案至少适用于上述两种RAN架构。后续为统一描述，将用于终端连接态传输的终端唯一标识称为终端空口传输唯一标识，具体的，该标识在传统LTE中即为C-RNTI。Inactive态的终端在区域内唯一标识称为inactive UE ID。而网络侧无线信令和数据收发节点不管是部署结构一中的eNB或部署结构二中的CU/DU(具体收发点为TRP)，都统称为基站。则本申请实施例中提供的技术方案如下：The technical solutions provided in the embodiments of the present application are applicable to at least the foregoing two RAN architectures. The subsequent description is a unified description, and the terminal unique identifier for the terminal connection state transmission is referred to as a terminal air interface transmission unique identifier. Specifically, the identifier is C-RNTI in the legacy LTE. A terminal in an inactive state is uniquely identified in the area as an inactive UE ID. The network side wireless signaling and data transceiving node is either the eNB in the deployment structure 1 or the CU/DU in the deployment structure 2. The sending and receiving points are TRP), which are collectively referred to as base stations. The technical solutions provided in the embodiments of the present application are as follows:

或者，无线承载是根据业务与UE保留的DRB的映射关系，通过确定需要向当前服务的基站发送的数据所属的业务确定的DRB。Alternatively, the radio bearer is a DRB determined by determining a service to which the data to be transmitted to the currently serving base station belongs according to the mapping relationship between the service and the DRB reserved by the UE.

下面用实例进行说明，在说明过程中，将按默认的按预设配置建立的DRB、保留的DRB、SRB2、SRB1的分类进行说明，在每一个分类中将先说明UE至核心网的上行数据传输的实施，然后对核心网至UE的下行数据传输的实施进行说明。The following is an example. In the description process, the classification of the DRB, reserved DRB, SRB2, and SRB1 established by default according to the default configuration will be described. In each category, the uplink data of the UE to the core network will be described first. The implementation of the transmission then illustrates the implementation of the downlink data transmission from the core network to the UE.

实施例1：Example 1:

本实施例是采用默认DRB进行数据传输的方案。This embodiment is a scheme for data transmission using a default DRB.

一、上行传输。First, the uplink transmission.

当UE由于长期没有数据发送而进入省电的Inactive状态之后，如果UE移出其anchor基站的覆盖范围，目前附着在新的服务基站之下。After the UE enters the power-saving Inactive state due to long-term no data transmission, if the UE moves out of the coverage of its anchor base station, it is currently attached under the new serving base station.

如果此时UE有上行数据需要发送，其可以如下：If the UE has uplink data to be sent at this time, it can be as follows:

1、UE有上行数据需要发送，UE首先需要判断一下，当前服务基站是否为其anchor基站，如果是anchor基站之外的其它基站，则UE需要为上行数据新建立一个默认DRB，该DRB的ID为预配置的，且DRB相关的层1层2的相关配置也都是预配置好的，预配置的方式可以如下：1. The UE has uplink data to be transmitted. The UE needs to determine whether the current serving base station is its anchor base station. If it is another base station other than the anchor base station, the UE needs to newly establish a default DRB for the uplink data, and the ID of the DRB. For pre-configured, DRB-related Layer 1 Layer 2 related configurations are also pre-configured, pre-configured The way to set it can be as follows:

(1)使用标准来进行规定，一种方式是用标准规定一套默认DRB配置和ID，所有UE所有业务都使用该配置和ID，或者为不同的业务/不同的UE类型规定不同的配置表和ID list，由UE根据自己的类型和业务种类进行选择，选择的方式可以是标准化的；(1) Use the standard to specify. One way is to use the standard to specify a default DRB configuration and ID. All UEs use this configuration and ID for all services, or specify different configuration tables for different services/different UE types. And the ID list, which is selected by the UE according to its own type and service type, and the manner of selection may be standardized;

UE进入inactive状态之前，由网络侧专用信令配置，可以是一套配置和ID，用于所有业务，也可以是多套配置和ID，根据业务类型不同选择不同，选择方式可以在配置同时携带。Before the UE enters the inactive state, it is configured by the network-side dedicated signaling. It can be a set of configurations and IDs, which can be used for all services, or multiple sets of configurations and IDs. Different types of services can be selected according to different service types. .

(2)采用其他方式，例如当前服务基站的通知，或者UE签约信息规定等。(2) Adopt other methods, such as notification of the current serving base station, or UE subscription information regulations.

2、在使用DRB向当前服务的基站发送所述数据时，层二的状态变量是从初始值开始的。2. When the DRB is used to send the data to the currently serving base station, the state variable of layer two starts from the initial value.

具体的，UE使用该默认的DRB进行业务数据的传输，由于这是一个新建立的DRB，其层二的各种状态变量均是从初始值开始，例如0。传输方式可以是UE请求网络侧给予专用资源，或者是在上行竞争资源上发送，UE在上行的信息中需要携带自己的inactive ID；也即，在使用所述按预设配置建立的DRB向当前服务的基站发送所述数据时，还可以进一步包括：Specifically, the UE uses the default DRB to perform service data transmission. Since this is a newly established DRB, various state variables of layer 2 start from an initial value, for example, 0. The transmission mode may be that the UE requests the network side to give the dedicated resource, or is sent on the uplink contention resource, and the UE needs to carry its own inactive ID in the uplink information; that is, the DRB established by using the preset configuration is currently used. When the serving base station sends the data, it may further include:

通知基站UE的inactive ID。。The inactive ID of the base station UE is notified. .

具体的，实现方式可以有很多，例如可以在发送的上行的信息中携带UE的inactive ID，用第一条上行信息携带ID，双方确认身份之后，后续可能以其他ID交互，也可以继续使用该ID。Specifically, the implementation manner may be any. For example, the inactive ID of the UE may be carried in the sent uplink information, and the ID is carried by the first uplink information. After the two parties confirm the identity, the following may interact with other IDs, and may continue to use the ID. ID.

3、对于网络侧来说，当接收到UE的数据和inactive ID，当前服务基站获知这是一个inactive状态的UE，如果默认DRB的配置当前服务基站是知道的，例如标准规定或者当前基站配置，则当前服务基站可以直接建立一个对应的DRB用于处理该UE的数据，如果不知道则可以向UE的anchor基站请求UE的上下文数据，以获取相关信息。3. For the network side, when receiving the data and the inactive ID of the UE, the current serving base station learns that this is an inactive state UE. If the default DRB configuration is known to the current serving base station, for example, the standard specification or the current base station configuration, The current serving base station may directly establish a corresponding DRB for processing data of the UE, and if not, may request the context data of the UE from the anchor base station of the UE to obtain related information.

具体实施中，UE的inactive ID里携带有anchor基站的ID信息和部分UE ID信息，因此当前服务基站可以准确无误的找到anchor基站，并进一步获取到UE信息，需要获取的UE信息主要有：In the specific implementation, the inactive ID of the UE carries the ID information of the anchor base station and the partial UE ID information. Therefore, the current serving base station can accurately find the anchor base station and further obtain the UE information, and the UE information that needs to be acquired mainly includes:

按预设配置建立的DRB的配置信息，具体的，默认DRB配置，如果该默认DRB信息服务基站不清楚，则需要向anchor基站获取相关配置；The configuration of the DRB is configured according to the default configuration. Specifically, the default DRB configuration. If the default DRB information service base station is unclear, you need to obtain the relevant configuration from the anchor base station.

UE安全相关参数信息，具体的，UE安全相关内容，如果开启了安全如加密等，需要获取安全参数例如密钥和加密算法等；UE security related parameter information, specifically, UE security related content, if security such as encryption is enabled, security parameters such as a key and an encryption algorithm are required to be acquired;

UE相关业务所对应的核心网承载信息，具体的，UE相关业务所对应的核心网承载信息，例如服务网关(Serving Gateway，SGW)信息，管道信息，如演进分组系统(Evolved Packet System，EPS)承载对应的隧道端点标识(Tunnel End Point Identifier，TEID)等。The core network bearer information corresponding to the UE related service, specifically, the core network bearer letter corresponding to the UE related service For example, the Serving Gateway (SGW) information, the pipe information, such as the Evolved Packet System (EPS) bearer corresponding Tunnel End Point Identifier (TEID), and the like.

当前服务基站获取了UE信息之后，可以对UE的数据进行处理，进而将UE信息发给对应的核心网用户面节点，或者UE的anchor基站，由其进行后续传输。也即：After the current serving base station obtains the UE information, the data of the UE may be processed, and then the UE information is sent to the corresponding core network user plane node, or the anchor base station of the UE, for subsequent transmission. That is:

一种是服务基站获取详细UE信息，由服务基站解析UE数据，直接发送给核心网节点；One is that the serving base station obtains detailed UE information, and the serving base station parses the UE data and directly sends the information to the core network node;

另一种，服务基站将UE的底层数据直接发送给anchor基站，由anchor基站解析之后发送给核心网节点。Alternatively, the serving base station directly sends the underlying data of the UE to the anchor base station, and is parsed by the anchor base station and then sent to the core network node.

二、下行传输。Second, downlink transmission.

如果inactive UE有下行数据需要发送，其可以如下：If the inactive UE has downlink data to send, it can be as follows:

对于核心网来说，其认为inactive UE附着在anchor基站下，因此该UE的数据会先发送到anchor基站，然后anchor基站会发起对该UE的寻呼过程，获得UE当前服务基站地址，anchor基站将UE下行数据发送到UE当前服务基站，同时会携带一些UE的上下文信息，上下文信息可以包括：For the core network, the inactive UE is considered to be attached to the anchor base station, so the data of the UE is first sent to the anchor base station, and then the anchor base station initiates a paging procedure for the UE, obtaining the current serving base station address of the UE, and the anchor base station. Sending the downlink data of the UE to the current serving base station of the UE, and carrying the context information of the UE, the context information may include:

默认DRB配置，如果该默认DRB不是由标准规定或者服务基站规定，而是由anchor基站与UE之间商定，则需要传递该信息，否则不需要；Default DRB configuration, if the default DRB is not specified by the standard or specified by the serving base station, but is negotiated between the anchor base station and the UE, the information needs to be transmitted, otherwise it is not required;

UE安全相关内容，如果需要开启安全如加密等，需要获取安全参数例如密钥和加密算法等；UE security related content, if you need to enable security such as encryption, you need to obtain security parameters such as keys and encryption algorithms;

当前服务基站获取了UE信息和数据之后，以默认DRB的配置，向UE发送其下行数据。After the current serving base station acquires the UE information and data, it sends its downlink data to the UE in the configuration of the default DRB.

UE接收到该下行数据，以约定好的默认DRB的配置进行处理，解析出用户数据，发送到高层。The UE receives the downlink data, processes the configuration of the default DRB, and parses the user data and sends it to the upper layer.

实施中，在通过按预设配置建立的DRB发送数据时，本次建立的DRB的ID与上一次建立后删除的DRB的ID不同。In the implementation, when the data is transmitted through the DRB established by the preset configuration, the ID of the DRB established this time is different from the ID of the DRB deleted after the last establishment.

具体的，如果需要对UE的上下行数据采取默认的新建DRB来发送，并且启动安全，则每次DRB的ID需要不同。例如DRB 0-29为正常的连接态DRB所使用的ID区间。而DRB30-100为inactive状态UE所使用的默认DRB的区间，则UE第一次发送数据时，使用DRB30，此次数据发送完毕后，该DRB删除。下一次使用，需要使用DRB31，依次类推。Specifically, if the default new DRB is required to be sent to the uplink and downlink data of the UE, and the security is started, the ID of each DRB needs to be different. For example, DRB 0-29 is the ID interval used by the normal connected state DRB. The DRB 30-100 is the default DRB interval used by the UE in the inactive state. When the UE sends data for the first time, the DRB 30 is used. After the data is sent, the DRB is deleted. The next time you use it, you need to use DRB31, and so on.

实施例2：Example 2:

本实施例是采用业务对应DRB进行数据传输的方案。 This embodiment is a scheme for performing data transmission by using a service corresponding DRB.

一、上行传输。First, the uplink transmission.

UE有上行数据需要发送，则UE直接选择该业务所对应的DRB来进行传输；The UE has uplink data to be sent, and the UE directly selects the DRB corresponding to the service to perform transmission;

UE进入inactive之后，之前UE连接态的DRB有可能是全部保留的，因为业务并没有结束，因此业务对应的DRB全部保留。也或者，长期没有数据，在进入inactive之前，只保留其中的一个DRB或者几个DRB，并将业务到DRB的映射规则进行一定的配置，如果是一个DRB，则UE所有数据均映射到该DRB，如果几个DRB可能优先级和配置不同，会配置满足哪些特性的数据映射到高优先级或者高配置的DRB上，其余业务映射到低优先级或者低配置的DRB上。After the UE enters inactive, the DRB of the previous UE connection state may be all reserved, because the service does not end, so the DRB corresponding to the service is all retained. Or, if there is no data for a long time, only one DRB or several DRBs are reserved before the inactive is entered, and the mapping rule of the service to the DRB is configured. If it is a DRB, all the data of the UE is mapped to the DRB. If the priorities of the DRBs are different, the configurations of the DRBs are mapped to the high-priority or high-configuration DRBs, and the remaining services are mapped to the low-priority or low-configuration DRBs.

容易知晓，UE进入Inactive之前，由网络侧决定，UE和anchor基站都会保留一定的DRB配置和实体，以及DRB与业务的映射规则，双方关于这些DRB的状态是同步的。It is easy to know that before the UE enters Inactive, it is determined by the network side that both the UE and the anchor base station reserve a certain DRB configuration and entity, and the mapping rules of the DRB and the service, and the states of the DRBs are synchronized.

对于网络侧UE当前服务基站说，当接收到UE的数据和inactive ID，当前服务基站获知这是一个inactive状态的UE，如果当前服务基站恰好就是UE的anchor基站，则也保留有UE的全部DRB信息，此时可以对UE的数据以相关DRB配置来处理，之后传递给核心网用户面实体。如果当前服务基站并不是UE的anchor基站，则当前服务基站需要将UE的底层数据发送给anchor基站处理，或者向anchor基站请求该UE的信息。For the current serving base station of the network side UE, when receiving the data and the inactive ID of the UE, the current serving base station learns that this is an inactive state UE. If the current serving base station happens to be the anchor base station of the UE, all the DRBs of the UE are also retained. Information, at this time, the data of the UE can be processed in the relevant DRB configuration, and then transmitted to the core network user plane entity. If the current serving base station is not the anchor base station of the UE, the current serving base station needs to send the underlying data of the UE to the anchor base station for processing, or request the information of the UE from the anchor base station.

UE的inactive ID里携带有anchor基站的ID信息和部分UE ID信息，因此当前服务基站可以准确无误的找到anchor基站，并进一步找到UE信息，需要获取的UE信息可以有：The inactive ID of the UE carries the ID information of the anchor base station and the partial UE ID information. Therefore, the current serving base station can find the anchor base station accurately and further find the UE information. The UE information that needs to be obtained may include:

相关的DRB配置和状态信息，UE发送数据所使用的DRB的配置和所有传输状态信息，例如传输变量的取值；Related DRB configuration and status information, configuration of the DRB used by the UE to transmit data, and all transmission status information, such as values of transmission variables;

UE安全相关内容，如果开启了安全如加密等，需要获取安全参数例如密钥和加密算法等；UE security-related content, if security such as encryption is enabled, security parameters such as keys and encryption algorithms need to be obtained;

UE相关业务所对应的核心网承载信息，例如SGW信息，管道信息(EPS承载对应的TEID等)。Core network bearer information corresponding to the UE-related service, such as SGW information, pipe information (TEID corresponding to the EPS bearer, etc.).

当前服务基站获取了UE信息之后，可以对UE的数据进行处理，进而将UE信息发给对应的核心网用户面节点，由其进行后续传输。After the current serving base station obtains the UE information, the UE may process the data of the UE, and then send the UE information to the corresponding core network user plane node for subsequent transmission.

UE在当前服务基站的传输，会更新先前状态变量信息，这是因为在保留承载的情况下，需要先获得UE的当前状态变量信息，在该信息上增加和更新，完成传输之后，还需要更新给锚点基站存储UE最新状态。所以还可以进一步包括：在使用保留的无线承载传输数据时，向锚点基站更新因数据传输而变化的先前状态变量信息。The previous state variable information is updated by the UE in the current serving base station. This is because, in the case of the reserved bearer, the current state variable information of the UE needs to be obtained first, and the information is added and updated. After the transmission is completed, it is required. The update to the anchor base station is to store the latest state of the UE. Therefore, the method further includes: updating the previous state variable information that is changed due to the data transmission to the anchor base station when the data is transmitted using the reserved radio bearer.

具体的，例如，如果是确认模式(Acknowledged Mode，AM)，UE之前已经发送了序列号(Sequence Number，SN)为1-5的数据，当前会发送SN为6的数据，这次数据发送将采取及时反馈确认的方式，例如在最后一个数据包中携带P bit，要求对所有此次发送的数据进行确认，还可以引入L2信令交互过程，保证双方确知此次数据发送已经结束，并且全部确认正确接收。Specifically, for example, if it is an Acknowledged Mode (AM), the UE has previously sent data with a sequence number (SN) of 1-5, and currently sends data with a SN of 6, this time the data will be sent. The method of timely feedback confirmation, for example, carrying the P bit in the last data packet, requires confirmation of all the data sent this time, and can also introduce an L2 signaling interaction process to ensure that both parties know that the data transmission has ended, and Confirm all receipts correctly.

实施中，还可以进一步包括以下处理之一或者其组合：In the implementation, one of the following processes or a combination thereof may be further included:

在PDCP层进行处理时，对从锚点基站获取的SN和/或Count连续维护；When processing is performed at the PDCP layer, the SN and/or Count acquired from the anchor base station are continuously maintained;

在保证传输的层进行处理时，将进入inactive状态时的传输状态复位；When the layer of the guaranteed transmission is processed, the transmission state when entering the inactive state is reset;

在保证传输的层进行处理时，在每次数据传输结束之后将传输状态复位；When the layer of the transmission is guaranteed to be processed, the transmission state is reset after each data transmission is ended;

在保证传输的层进行处理时，在更换服务基站之后将传输状态复位。When the layer of the guaranteed transmission is processed, the transmission state is reset after the replacement of the serving base station.

具体的，由于负责安全的层，例如PDCP，出于安全考虑，其SN需要的连续，即UE在进入inactive状态时，PDCP Count(计数)值为500，则后续发包Count值不断增加，连续维护。而其他仅仅是保证传输的层，例如RLC和MAC，其状态可以每次进行复位，例如Inactive UE处于服务基站1时，需要发送数据，服务基站1与anchor基站不同，则RLC状态变量采取从初始值开始，例如0，本次发送完毕，RLC对等端确认所有数据均成功发送成功接收，则RLC层对等端之间可以信令交互，复位RLC，重新从初始值开始，例如0。或者当UE来到了新的服务基站，则复位RLC。Specifically, due to security layer, such as PDCP, for security reasons, the SN needs to be continuous, that is, when the UE enters the inactive state, the PDCP Count value is 500, and the subsequent packet Count value is continuously increased, and the continuous maintenance is performed. . Others are only layers that guarantee transmission, such as RLC and MAC, whose status can be reset every time. For example, when the Inactive UE is in the serving base station 1, data needs to be transmitted. The serving base station 1 is different from the anchor base station, and the RLC state variable is taken from the initial. The value starts, for example, 0. After the transmission is completed, the RLC peer confirms that all data is successfully transmitted successfully, and the RLC layer peers can perform signaling interaction, reset the RLC, and start from the initial value, for example, 0. Or when the UE comes to a new serving base station, the RLC is reset.

另外，更换基站是指UE移动到其它基站，服务基站发生变化时的情况。In addition, the replacement of the base station refers to a situation in which the UE moves to another base station and the serving base station changes.

二、下行传输。Second, downlink transmission.

对于核心网来说，认为inactive UE附着在anchor基站下，因此该UE的数据会先发送到anchor基站，然后anchor基站会发起对UE的寻呼过程，获得UE当前服务基站地址，anchor基站将UE下行数据发送到UE当前服务基站，同时会携带一些UE的上下文信息，可能包括：For the core network, the inactive UE is considered to be attached to the anchor base station, so the data of the UE is first sent to the anchor base station, and then the anchor base station initiates a paging procedure for the UE, obtaining the current serving base station address of the UE, and the anchor base station will be the UE. The downlink data is sent to the current serving base station of the UE, and carries some context information of the UE, which may include:

数据无线承载配置和状态信息，该数据无线承载应该是业务对应的数据无线承载；Data radio bearer configuration and status information, the data radio bearer should be the data radio bearer corresponding to the service;

当前服务基站获取了UE信息和数据之后，以数据无线承载的配置和状态变量，向UE发送其下行数据。 After the current serving base station acquires the UE information and data, it sends its downlink data to the UE in the configuration and state variables of the data radio bearer.

UE接收到该下行数据，以相关数据无线承载的配置和状态变量进行处理，解析出用户数据，发送到高层。The UE receives the downlink data, processes the configuration and state variables of the relevant data radio bearer, parses the user data, and sends the data to the upper layer.

实施中，还可以进一步包括：In the implementation, it may further include:

在数据传输结束后，采取层二信令的方式进行显式的复位处理。如果是需要对某些层进行传输结束的复位，则可以采取层二信令的方式，进行显式的复位处理。After the end of the data transmission, an explicit reset process is performed by means of layer two signaling. If it is necessary to reset the transmission end of some layers, the layer 2 signaling can be adopted to perform explicit reset processing.

在UE在该UE的锚点基站所保留的数据无线承载上发起对应的业务时，采用连续的安全层状态变量，其它层的状态变量每次从初始值开始。UE隔一段时间，再次发起的业务，其安全层状态变量是连续的，而其他层的状态变量是每次从初始值开始的。When the UE initiates a corresponding service on the data radio bearer reserved by the anchor base station of the UE, a continuous security layer state variable is used, and the state variables of other layers start from the initial value each time. The UE initiates the service again, and its security layer state variables are continuous, while the other layer's state variables start from the initial value each time.

具体实施中，UE使用该业务对应的原始DRB配置和状态变量，完成了此次上行/下行的传输。需要注意的是，此次传输，必然会对状态变量的取值，尤其是需要连续的安全层的状态变量的取值进行了更新，例如安全层count值由原来的500，增加到了505，意味着新发送了5个数据包，因为安全层的状态变量是需要连续的，因此业务结束之后，当前服务基站需要将维持连续的状态变量的更新值通知给anchor基站。Anchor基站会存储更新该变量。当下次UE需要发送数据时，count值从506开始计数。连续状态变量的存储可以是双方向的，例如对于网络侧来说，其记录下行发送到505，上行接收到302等。其它层的状态变量，如果是已经复位，则不需要通知anchor基站，下次从初始值开始，如果其它层也有需要连续的状态变量，则也需要通知给anchor基站。In the specific implementation, the UE completes the uplink/downlink transmission by using the original DRB configuration and the state variable corresponding to the service. It should be noted that this transmission will inevitably update the value of the state variable, especially the value of the state variable that needs continuous security layer. For example, the security layer count value is increased from the original 500 to 505, which means The new data packet is sent because the security layer's state variable needs to be continuous. Therefore, after the service ends, the current serving base station needs to notify the anchor base station of the updated value of the continuous state variable. The Anchor base station will store and update this variable. When the next time the UE needs to transmit data, the count value starts counting from 506. The storage of the continuous state variable may be bidirectional. For example, for the network side, the record downlink is sent to 505, the uplink is received to 302, and the like. The state variables of other layers, if they have been reset, do not need to notify the anchor base station, and the next time starting from the initial value, if other layers also need continuous state variables, it is also necessary to notify the anchor base station.

实施例3：Example 3:

本实施例是采用NAS信令SRB2进行数据传输的方案。This embodiment is a scheme for data transmission using NAS signaling SRB2.

一、上行传输。First, the uplink transmission.

如果UE有上行数据需要发送，则可以如下：If the UE has uplink data to send, it can be as follows:

可以将数据放置在NAS信令中，以恢复的SRB2或者以新建的默认SRBi进行发送；The data can be placed in the NAS signaling, and the recovered SRB2 or sent with the newly created default SRBi;

恢复的SRB2是指UE之前维护的一条信令承载，UE保存有其全部的配置和状态变量取值，可以直接在SRB2发送新数据。对于网络侧来说，当前服务基站可以将接收到的底层数据直接发送给UE的anchor基站进行后续处理，也可以向anchor基站请求UE的上下文信息，例如SRB2配置和状态信息、核心网用户面通路信息，解析出NAS信令信息，并按照核心网用户面通路信息，发送到相应的核心网控制实体，进行NAS信令的解析，后续解析出数据，进行数据处理。The recovered SRB2 refers to a signaling bearer previously maintained by the UE. The UE saves all its configuration and state variable values, and can directly send new data in SRB2. For the network side, the current serving base station may directly send the received underlying data to the anchor base station of the UE for subsequent processing, or may request the anchor base station for context information of the UE, such as SRB2 configuration and status information, and the core network user plane path. Information, parsing out NAS signaling information, and According to the information of the core network user plane, it is sent to the corresponding core network control entity to perform NAS signaling analysis, and subsequently parse the data for data processing.

新建的默认SRBi实施中可以采用类似于默认DRB的方式，UE和当前服务基站均采取默认的SRBi的配置来进行NAS信令传输，后续当前服务基站可以将数据转发给Anchor基站处理，也可以直接获取UE的信息，解析之后发送至核心网控制面实体，进行NAS信令的解析，后续解析出数据，进行数据处理。The new default SRBi implementation can adopt a mode similar to the default DRB. Both the UE and the current serving base station adopt the default SRBi configuration for NAS signaling transmission. The current serving base station can forward the data to the Anchor base station for processing. The information of the UE is obtained, and then parsed and sent to the core network control plane entity, and the NAS signaling is parsed, and the data is parsed and processed.

二、下行传输。Second, downlink transmission.

下行数据发送时，如果放置在NAS信令中，则由核心网控制面实体发送给UE的anchor基站，anchor基站将NAS信令和传输配置发送给当前服务基站，由当前服务基站发送给UE。承载类型也是恢复的SRB2或者新建的默认SRBi。When the downlink data is transmitted, if it is placed in the NAS signaling, the core network control plane entity sends the anchor base station to the UE, and the anchor base station sends the NAS signaling and transmission configuration to the current serving base station, and the current serving base station sends the signal to the UE.

RRC信令携带UE数据，需要携带数据的具体信息，还需要显式指示数据的类型，例如根据已有的DRB，应该对应到哪一个DRB中，或者根据流特性，以便于从RRC信令中解析出数据之后，能够得知如何与核心网的数据通路进行映射。The RRC signaling carries the UE data, and needs to carry the specific information of the data, and also needs to explicitly indicate the type of the data, for example, according to the existing DRB, which DRB should be corresponding to, or according to the flow characteristics, in order to facilitate the RRC signaling. After parsing the data, it is possible to know how to map to the data path of the core network.

恢复的SRB1是指UE之前维护的一条信令承载，UE保存有其全部的配置和状态变量取值，可以直接在SRB1发送新数据。对于网络侧来说，当前服务基站可以将接收到的底层数据直接发送给UE的anchor基站进行后续处理，也可以向anchor基站请求UE的上下文信息，例如SRB1配置和状态信息、核心网用户面通路信息，解析出RRC信令里的数据，并按照核心网用户面通路信息，发送到相应的核心网用户面实体，进行后续数据处理。The recovered SRB1 refers to a signaling bearer previously maintained by the UE. The UE saves all its configuration and state variable values, and can directly send new data in SRB1. For the network side, the current serving base station may directly send the received underlying data to the anchor base station of the UE for subsequent processing, or may request the context information of the UE from the anchor base station, such as SRB1 configuration and status information, and the core network user plane path. The information is parsed out in the RRC signaling, and sent to the corresponding core network user plane entity according to the core network user plane information, for subsequent data processing.

新建的默认SRBj在实施中可以采用类似于默认DRB的方式，UE和当前服务基站均采取默认的SRBj的配置来进行RRC信令传输，后续当前服务基站可以将数据转发给Anchor基站处理，也可以直接获取UE的信息，从RRC信令中解析出数据包，解析之后发送至核心网用户面实体，进行后续数据处理。The new default SRBj can be implemented in a manner similar to the default DRB. Both the UE and the current serving base station adopt the default SRBj configuration for RRC signaling transmission. The current serving base station can forward the data to the Anchor base station for processing. The information of the UE is directly obtained, and the data packet is parsed from the RRC signaling, and then parsed and sent to the core network user plane entity for subsequent data processing.

二、下行传输。 Second, downlink transmission.

下行数据发送，则由核心网用户面实体发送给UE的anchor基站，anchor基站将数据和传输配置发送给当前服务基站，由当前服务基站放置在RRC信令中发送给UE。承载类型也是恢复的SRB1或者新建的默认SRBj。The downlink data transmission is sent by the core network user plane entity to the anchor base station of the UE, and the anchor base station sends the data and the transmission configuration to the current serving base station, and the current serving base station is placed in the RRC signaling and sent to the UE.
