Description

删除数据无线承载的方法、用户设备以及接入网功能实体Method for deleting data radio bearer, user equipment, and access network functional entity 技术领域Technical field
本发明涉及通信技术领域，尤其涉及一种删除数据无线承载的方法、用户设备以及接入网功能实体。The present invention relates to the field of communications technologies, and in particular, to a method for deleting a data radio bearer, a user equipment, and an access network functional entity.
背景技术Background technique
第五代移动通信(5th-Generation，5G)通信技术/下一代移动通信(Next Generation)，与第二代(Second Generation，2G)、第三代(3rd-Generation，3G)和长期演进(Long Term Evolution，LTE)网络相比，可以提供更高速的数据服务。在5G架构中，用户设备(User Equipment，UE)通过接入网(Access Network，AN)接入下一代核心网(Next Generation Core Network，NGCN)。Fifth-generation mobile communication (5th-Generation, 5G) communication technology / Next Generation, and Second Generation (2G), third generation (3rd-Generation, 3G) and long-term evolution (Long Compared with the Term Evolution (LTE) network, it can provide higher speed data services. In the 5G architecture, the user equipment (User Equipment, UE) accesses the Next Generation Core Network (NGCN) through an Access Network (AN).
在5G架构中，UE和AN之间基于无线承载(Radio Bearer，RB)进行数据和信令的传输，其中用于数据传输的RB为数据无线承载(Data Radio Bearer，DRB)。DRB的建立由AN确定，AN可以根据需要灵活的建立多个DRB，也可以根据需求删除已经建立的承载，如当AN与UE之间的DRB数目达到上限时，需要对DRB进行删除。In the 5G architecture, data and signaling are transmitted between the UE and the AN based on a Radio Bearer (RB), where the RB for data transmission is a Data Radio Bearer (DRB). The establishment of the DRB is determined by the AN. The AN can flexibly establish multiple DRBs as needed, and can also delete the established bearers according to requirements. For example, when the number of DRBs between the AN and the UE reaches the upper limit, the DRB needs to be deleted.
在现有LTE架构中，删除DRB主要由分组数据网网关(Packet Data Network Gateway，PGW)发起。首先，PGW通过服务网关(Serving Gateway，SGW)向移动性管理网元(Mobility Management Entity，MME)发送删除演进分组系统(Evolved Packet System，EPS)承载请求；然后，MME向基站eNB发送去激活请求；最后，eNB根据MME的去激活请求使用无线资源控制(Radio Resource Control，RRC)重配置流程删除EPS承载对应的DRB。In the existing LTE architecture, the delete DRB is mainly initiated by a Packet Data Network Gateway (PGW). First, the PGW sends an Evolved Packet System (EPS) bearer request to the Mobility Management Entity (MME) through a Serving Gateway (SGW); then, the MME sends a deactivation request to the base station eNB. Finally, the eNB deletes the DRB corresponding to the EPS bearer by using a Radio Resource Control (RRC) reconfiguration process according to the MME's deactivation request.
在上述删除DRB的方案中，由于EPS承载是端到端的建立，一个EPS承载映射到一个DRB，因此，承载的删除也是端到端的，即网络侧决定删除EPS承载时，会同时触发删除对应的DRB。但是，在5G中，核心网 不感知DRB，无法发起DRB承载的删除过程。In the above-mentioned scenario of deleting the DRB, since the EPS bearer is end-to-end, an EPS bearer is mapped to a DRB. Therefore, the bearer deletion is also end-to-end. That is, when the network side decides to delete the EPS bearer, it will trigger the deletion correspondingly. DRB. However, in 5G, the core network The DRB bearer deletion process cannot be initiated without being aware of the DRB.

具体实施方式detailed description
下面结合附图，对本发明的实施例进行描述。Embodiments of the present invention will be described below with reference to the accompanying drawings.
为了更好的理解本发明实施例，下面先对本发明实施例公开的一种5G系统架构进行描述。请参阅图1，图1是本发明实施例公开的一种5G系统架构示意图。 For a better understanding of the embodiments of the present invention, a 5G system architecture disclosed in the embodiment of the present invention is described below. Please refer to FIG. 1. FIG. 1 is a schematic diagram of a 5G system architecture disclosed in an embodiment of the present invention.
如图1所示，本发明实施例公开的一种5G系统架构可以包括用户设备UE101、接入网功能实体ANF102和核心网CN103，其中，CN103包括控制面节点CPF1031、用户面节点UPF1032和应用功能节点(Application Function，AF)1033。As shown in FIG. 1 , a 5G system architecture disclosed in the embodiment of the present invention may include a user equipment UE101, an access network function entity ANF102, and a core network CN103, where CN103 includes a control plane node CPF 1031, a user plane node UPF 1032, and an application function. Application Function (AF) 1033.
UE101可以通过ANF102接入CN103，UE101可以通过ANF102和UPF1032接收用户面数据，通过CPF1031接收控制面数据。CPF1031用于向UE101、ANF102、UPF1032和AF1033发送控制信令。The UE 101 can access the CN 103 through the ANF 102, and the UE 101 can receive user plane data through the ANF 102 and the UPF 1032, and receive control plane data through the CPF 1031. The CPF 1031 is used to transmit control signaling to the UE 101, the ANF 102, the UPF 1032, and the AF 1033.
UE101通过ANF102和UPF1032接收用户面数据时，UE101需要与ANF102建立数据无线承载DRB，DRB也称空口无线承载。UE101与ANF102可以建立多个DRB，用于传输不同类型的数据(例如，不同QoS属性的数据、不同GBR要求的数据等)。当UE101与ANF102建立的DRB长时间不用时，可以通过UE101或ANF102发起对DRB的删除，以保证资源的合理利用。When the UE 101 receives the user plane data through the ANF 102 and the UPF 1032, the UE 101 needs to establish a data radio bearer DRB with the ANF 102, and the DRB is also called an air interface radio bearer. The UE 101 and the ANF 102 may establish multiple DRBs for transmitting different types of data (eg, data of different QoS attributes, data required by different GBRs, etc.). When the DRB established by the UE 101 and the ANF 102 is not used for a long time, the DRB may be deleted by the UE 101 or the ANF 102 to ensure reasonable utilization of resources.
进一步的，核心网CN103中可以有多个CPF节点。其中CPF可以包含移动性管理功能(Mobility Management Function，MMF)和会话管理功能(Session Management Function，SMF)。MMF和SMF可以单独部署，也可以部署在一个功能实体中。Further, there may be multiple CPF nodes in the core network CN103. The CPF may include a Mobility Management Function (MMF) and a Session Management Function (SMF). MMF and SMF can be deployed separately or in a functional entity.
请参阅图2，图2是本发明实施例公开的一种删除数据无线承载的方法的流程示意图。图2提供了一种UE触发的删除DRB的方法，包括如下步骤。Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for deleting a data radio bearer according to an embodiment of the present invention. FIG. 2 provides a UE-triggered method for deleting a DRB, including the following steps.
201，UE获取目标数据无线承载DRB的标识，目标DRB为待删除的DRB。201. The UE acquires an identifier of the target data radio bearer DRB, where the target DRB is the DRB to be deleted.
202，UE向ANF发送删除无线承载请求，该删除无线承载请求携带目标DRB的标识，删除无线承载请求用于请求ANF根据目标DRB的标识删除目标DRB。202. The UE sends a delete radio bearer request to the ANF, where the delete radio bearer request carries the identifier of the target DRB, and the delete radio bearer request is used to request the ANF to delete the target DRB according to the identifier of the target DRB.
本发明实施例中，在执行步骤201之前，UE与ANF之间已经建立了至少一个DRB。In the embodiment of the present invention, at least one DRB has been established between the UE and the ANF before performing step 201.
UE可以根据预设的触发条件触发UE获取目标DRB的标识，目标DRB可以是UE与ANF之间已经建立的至少一个DRB中的一个或多个。预设的触发条件 可以是已经建立的DRB是否老化，也可以是已经建立的DRB的数量是否达到上限。例如，当UE与ANF之间已经建立的至少一个DRB中有DRB老化时，UE将老化的DRB作为目标DRB，触发UE发起DRB删除流程，执行步骤201-步骤202；当UE与ANF之间已经建立的DRB的个数达到上限时，如果需要建立新的DRB，则从UE与ANF之间已经建立的DRB中确定目标DRB，触发UE发起DRB删除流程，执行步骤201-步骤202。UE也可以在已经建立的DRB都没有老化或者已经建立的DRB的个数没有达到上限时，从UE与ANF之间已经建立的DRB中确定目标DRB，触发UE发起DRB删除流程，执行步骤201-步骤202。The UE may trigger the UE to acquire the identifier of the target DRB according to the preset trigger condition, where the target DRB may be one or more of the at least one DRB that has been established between the UE and the ANF. Preset trigger condition Whether the established DRB is aging or whether the number of established DRBs reaches the upper limit. For example, when there is a DRB aging in the at least one DRB that has been established between the UE and the ANF, the UE uses the aging DRB as the target DRB, triggers the UE to initiate the DRB deletion process, and performs steps 201-202; When the number of established DRBs reaches the upper limit, if a new DRB needs to be established, the target DRB is determined from the established DRBs between the UE and the ANF, and the UE is triggered to initiate the DRB deletion process, and steps 201-202 are performed. The UE may also determine the target DRB from the established DRBs between the UE and the ANF, and trigger the UE to initiate the DRB deletion process, if the number of the established DRBs is not aged or the number of established DRBs has not reached the upper limit, and the step 201- Step 202.
当UE获取目标DRB的标识之后，UE向ANF发送携带目标DRB的标识的删除无线承载请求，以使ANF根据目标DRB的标识删除目标DRB，其中，删除目标DRB即删除目标DRB对应的空口配置信息。ANF删除目标DRB后，即可释放DRB占用的空口资源，以便UE与ANF建立新的DRB。After the UE obtains the identifier of the target DRB, the UE sends a delete radio bearer request carrying the identifier of the target DRB to the ANF, so that the ANF deletes the target DRB according to the identifier of the target DRB, where the target DRB is deleted, that is, the air interface configuration information corresponding to the target DRB is deleted. . After the ANF deletes the target DRB, the air interface resources occupied by the DRB can be released, so that the UE establishes a new DRB with the ANF.
可选的，目标DRB包括以下至少一种：老化的DRB、所有业务已经结束的DRB以及服务质量规则全部被删除的DRB；其中，老化的DRB为连续空闲时间达到或者超过预设的老化时间的DRB。Optionally, the target DRB includes at least one of the following: an aged DRB, a DRB in which all services have been terminated, and a DRB in which the QoS rules are all deleted; wherein the aged DRB is a continuous idle time that reaches or exceeds a preset aging time. DRB.
本发明实施例中，每个DRB会对应一个预设的老化时间。当一个DRB在建立完成时，UE会启动计时。在计时期间，如果有数据在该DRB上传输，则重新启动计时，直到该DRB的连续空闲时间达到或者超过预设的老化时间时，UE将该DRB作为老化的DRB。不同的DRB对应的预设的老化时间可以不同，也可以相同。老化时间可以是运营商基于用户的信息来确定的，老化时间也可以基于QoS参数(例如，数据包优先级、丢包率、延时等)或者基于分组数据单元(Packet Data Unit，PDU)会话级别来确定。当一个DRB在超过老化时间的一段连续时间内处于空闲状态(空闲状态，即没有使用该DRB接收或者发送数据的状态)时，即表明该DRB为老化的DRB，UE获取该DRB的标识，并发起DRB删除流程。In this embodiment of the present invention, each DRB corresponds to a preset aging time. When a DRB is completed, the UE starts timing. During the timing, if there is data transmitted on the DRB, the timing is restarted until the continuous idle time of the DRB reaches or exceeds the preset aging time, and the UE regards the DRB as an aging DRB. The preset aging time corresponding to different DRBs may be different or the same. The aging time may be determined by the operator based on user information, and the aging time may also be based on QoS parameters (eg, packet priority, packet loss rate, delay, etc.) or based on Packet Data Unit (PDU) sessions. Level to determine. When a DRB is in an idle state (in an idle state, that is, a state in which the DRB is not used to receive or transmit data), the DRB is an aging DRB, and the UE acquires the identifier of the DRB, and Initiate the DRB deletion process.
其中，UE可以在与CPF建立PDU会话的过程中，从CPF获取DRB的老化时 间，当UE与ANF之间每建立一个DRB时，UE可以根据预先获取的该DRB对应的老化时间进行计时。The UE may obtain the aging time of the DRB from the CPF during the process of establishing a PDU session with the CPF. During the establishment of a DRB between the UE and the ANF, the UE may time according to the aging time corresponding to the DRB acquired in advance.
一个实施例中，DRB对应的业务可以包括QQ、微信等业务。当UE判断一个DRB对应的所有业务已经结束时，即将该DRB作为目标DRB。在一个场景中，当UE与ANF之间建立一个DRB后，使用该DRB进行数据业务传输，当该数据业务结束时，即将该DRB作为目标DRB。In an embodiment, the service corresponding to the DRB may include services such as QQ and WeChat. When the UE determines that all services corresponding to one DRB have ended, the DRB is regarded as the target DRB. In a scenario, after a DRB is established between the UE and the ANF, the DRB is used for data service transmission. When the data service ends, the DRB is used as the target DRB.
在一个实施例中，服务质量规则全部被删除的DRB为目标DRB。服务质量，即为通信网络提供服务的能力。为了满足一个DRB可以传输多种不同服务质量(Quality of Service，QoS)的数据的要求，一个DRB可以对应一个或多个服务质量规则(QoS规则)，当DRB使用不同的QoS规则时，该DRB传输的数据满足不同的QoS。当DRB对应的一个服务质量规则长时间不使用时，可以删除该服务质量规则，当该DRB对应的所有服务质量规则都已经被删除时，UE确定该DRB为目标DRB。In one embodiment, the DRB whose QoS rules are all deleted is the target DRB. Quality of service, the ability to provide services to a communication network. In order to meet the requirement that a DRB can transmit data of a plurality of different Quality of Service (QoS), one DRB may correspond to one or more quality of service rules (QoS rules), and when the DRB uses different QoS rules, the DRB The transmitted data meets different QoS. When a QoS rule corresponding to the DRB is not used for a long time, the QoS rule may be deleted. When all QoS rules corresponding to the DRB have been deleted, the UE determines that the DRB is the target DRB.

The first DRB is any one of the established DRBs between the UE and the ANF.
本发明实施例中，UE与ANF之间可以建立多个DRB，每个DRB会对应一个预设的老化时间。当一个DRB在建立完成时，会启动计时。在计时期间，如果有数据在该DRB上传输，则重新启动计时，当计时的时长达到或者超过该DRB的老化时间时，UE获取该第一DRB的标识。In the embodiment of the present invention, multiple DRBs may be established between the UE and the ANF, and each DRB corresponds to a preset aging time. Timing is initiated when a DRB is completed. During the timing, if there is data transmitted on the DRB, the timing is restarted. When the duration of the timing reaches or exceeds the aging time of the DRB, the UE acquires the identifier of the first DRB.
可选的，步骤201中UE获取目标DRB的标识的方式具体可以为：Optionally, the method for the UE to obtain the identifier of the target DRB in step 201 may be specifically:
若UE与ANF之间已建立的DRB的个数达到预设的上限值，则UE确定目标DRB，获取目标DRB的标识。If the number of established DRBs between the UE and the ANF reaches a preset upper limit, the UE determines the target DRB and obtains the identifier of the target DRB.
本发明实施例中，当UE与ANF之间已建立的DRB的个数已经达到上限值时，如果需要建立新的DRB，则从UE与ANF之间已经建立的DRB中确定目标 DRB，触发UE发起DRB删除流程。当UE与ANF之间已建立的DRB的个数没有达到上限值时，UE也可以将老化的DRB、所有业务已经结束的DRB以及服务质量规则全部被删除的DRB删除，还可以在已建立的DRB的个数没有达到上限时，尽可能的防止建立的DRB的个数达到上限，保证了资源的合理利用。In the embodiment of the present invention, when the number of established DRBs between the UE and the ANF has reached the upper limit, if a new DRB needs to be established, the target is determined from the established DRB between the UE and the ANF. The DRB triggers the UE to initiate a DRB deletion process. When the number of established DRBs between the UE and the ANF does not reach the upper limit, the UE may also delete the aged DRB, the DRBs whose services have been completed, and the DRBs whose service quality rules are all deleted. When the number of DRBs does not reach the upper limit, the number of established DRBs is prevented from reaching the upper limit as much as possible, thereby ensuring the rational use of resources.
当UE需要建立新的DRB时，如果UE与ANF之间已建立的DRB的个数已经达到预设上限值，提供了一种UE触发的删除DRB的方法，可以灵活的删除DRB，释放DRB对应的空口资源，以满足新建DRB的需求，保证了资源的合理利用。When the UE needs to establish a new DRB, if the number of established DRBs between the UE and the ANF has reached the preset upper limit, a UE-triggered DRB deletion method is provided, which can flexibly delete the DRB and release the DRB.

The quality of service attributes (QoS attributes) can be classified into Guaranteed Bit Rate (GBR) and Non-Guaranteed Bit Rate (non-GBR). The UE may determine the target DRB to be deleted according to the QoS attribute corresponding to the established DRB. Specifically, for example, the UE may determine that the DRB whose QoS attribute is non-GBR is the target DRB that needs to be deleted. Alternatively, the UE determines the target DRB to be deleted according to the priority of the QoS attribute parameter used for establishing the DRB, that is, deletes the DRB with the lowest priority.
当UE需要建立新的DRB时，如果UE与ANF之间已建立的DRB的个数已经达到预设上限值(例如，预设上限值为8个)，无法再建立新的DRB时，此时从 UE与ANF之间已经建立的DRB中确定目标DRB，则UE获取目标DRB(待删除的DRB)的标识，触发UE发起DRB删除流程。When the UE needs to establish a new DRB, if the number of established DRBs between the UE and the ANF has reached the preset upper limit (for example, the preset upper limit is 8), a new DRB cannot be established. At this time from The UE determines the target DRB in the established DRB between the UE and the ANF, and the UE acquires the identifier of the target DRB (the DRB to be deleted), and triggers the UE to initiate the DRB deletion process.

本发明实施例中，一个DRB可以对应一个或多个QoS规则，每个QoS规则对应一个老化时间，老化时间可以是运营商基于用户的信息来确定的，老化时间的大小可以基于QoS参数(例如，数据包优先级、丢包率、延时等)或者基于分组数据单元(Packet Data Unit，PDU)会话级别来确定。当一个QoS规则的连续空闲时间达到或者超过对应的老化时间时，即一个QoS规则在连续的一段时间(老化时间)内没有被使用，则UE删除该QoS规则。当一个DRB对应的所有服务质量规则都被删除时，确定该DRB为目标DRB。在一个具体场景中，在创建或者获取一个QoS规则时，UE获取该QoS规则对应的老化时间，此时UE开始计时，如果在老化时间内，没有使用该QoS规则处理数据，则UE删除该QoS规则。In the embodiment of the present invention, one DRB may correspond to one or more QoS rules, and each QoS rule corresponds to an aging time, and the aging time may be determined by the operator based on user information, and the aging time may be based on QoS parameters (for example, , packet priority, packet loss rate, delay, etc.) or based on Packet Data Unit (PDU) session level. When a continuous idle time of a QoS rule reaches or exceeds a corresponding aging time, that is, a QoS rule is not used for a continuous period of time (aging time), the UE deletes the QoS rule. When all the quality of service rules corresponding to a DRB are deleted, it is determined that the DRB is the target DRB. In a specific scenario, when the QoS rule is created or obtained, the UE acquires the aging time corresponding to the QoS rule, and the UE starts timing.

请参阅图6，图6是本发明实施例公开的另一种删除数据无线承载的方法的流程示意图。图6提供了一种ANF触发的删除DRB的方法，包括如下步骤。Please refer to FIG. 6. FIG. 6 is a schematic flowchart diagram of another method for deleting a data radio bearer according to an embodiment of the present invention. FIG. 6 provides an ANF-triggered method for deleting a DRB, including the following steps.
601，ANF获取目标数据无线承载DRB的标识，目标DRB为待删除的DRB。601. The ANF obtains the identifier of the radio bearer DRB of the target data, and the target DRB is the DRB to be deleted.
602，ANF向UE发送删除无线承载请求，该删除无线承载请求携带目标DRB的标识，删除无线承载请求用于请求UE根据目标DRB的标识删除目标DRB。 602. The AIF sends a delete radio bearer request to the UE, where the delete radio bearer request carries the identifier of the target DRB, and the delete radio bearer request is used to request the UE to delete the target DRB according to the identifier of the target DRB.
本发明实施例中，在执行步骤601之前，UE与ANF之间已经建立了至少一个DRB。In the embodiment of the present invention, at least one DRB has been established between the UE and the ANF before performing step 601.
ANF可以根据预设的触发条件触发UE获取目标DRB的标识，目标DRB可以是ANF与UE之间已经建立的至少一个DRB中的一个或多个。预设的触发条件可以是已经建立的DRB是否老化，也可以是已经建立的DRB的数量是否达到上限。例如，当ANF与UE之间已经建立的至少一个DRB中有DRB老化时，ANF将老化的DRB作为目标DRB，触发ANF发起DRB删除流程，执行步骤601-步骤602；当ANF与UE之间已经建立的DRB的个数达到上限时，如果需要建立新的DRB，则从ANF与UE之间已经建立的DRB中确定目标DRB，触发ANF发起DRB删除流程，执行步骤601-步骤602。ANF也可以在已经建立的DRB都没有老化或者已经建立的DRB的个数没有达到上限时，从ANF与UE之间已经建立的DRB中确定目标DRB，触发ANF发起DRB删除流程，执行步骤601-步骤602。The ANF may trigger the UE to acquire the identifier of the target DRB according to the preset trigger condition, and the target DRB may be one or more of the at least one DRB that has been established between the ANF and the UE. The default triggering condition may be whether the established DRB is aging or whether the number of established DRBs reaches the upper limit. For example, when there is a DRB aging in at least one DRB that has been established between the ANF and the UE, the ANF takes the aging DRB as the target DRB, triggers the ANF to initiate the DRB deletion process, and performs steps 601-602; If the number of established DRBs reaches the upper limit, if a new DRB needs to be established, the target DRB is determined from the established DRBs between the ANF and the UE, and the ANF is triggered to initiate the DRB deletion process, and steps 601-602 are performed. The ANF may also determine the target DRB from the established DRB between the ANF and the UE, and trigger the ANF to initiate the DRB deletion process, if the number of the established DRBs is not aged or the number of established DRBs does not reach the upper limit, and the ANF is initiated to initiate the DRB deletion process. Step 602.
当ANF获取目标DRB的标识之后，ANF向UE发送携带目标DRB的标识的删除无线承载请求，以使UE根据目标DRB的标识删除目标DRB。UE删除目标DRB后，即可完成释放DRB占用的空口资源，以便UE与ANF建立新的DRB。After the ANF obtains the identifier of the target DRB, the ANF sends a delete radio bearer request carrying the identifier of the target DRB to the UE, so that the UE deletes the target DRB according to the identifier of the target DRB. After the UE deletes the target DRB, the air interface resource occupied by the DRB is released, so that the UE establishes a new DRB with the ANF.
可选的，目标DRB包括老化的DRB；其中，老化的DRB为连续空闲时间达到或者超过预设的老化时间的DRB。Optionally, the target DRB includes an aged DRB, where the aged DRB is a DRB whose continuous idle time reaches or exceeds a preset aging time.
本发明实施例中，每个DRB会对应一个预设的老化时间。当一个DRB在建立完成时，ANF会启动计时。在计时期间，如果有数据在该DRB上传输，则重新启动计时，直到该DRB的连续空闲时间达到或者超过预设的老化时间时，ANF将该DRB作为老化的DRB。不同的DRB对应的预设的老化时间可以不同，也可以相同。老化时间可以是运营商基于用户的信息来确定的，老化时间也可以基于QoS参数(例如，数据包优先级、丢包率、延时等)或者基于分组数据单元(Packet Data Unit，PDU)会话级别来确定。当一个DRB在超过老化时间的一段连续时间内处于空闲状态(空闲状态，即没有使用该DRB接收或者发送数据的状态)时，即表明该DRB为老化的DRB，ANF获取该DRB的标识，并 发起DRB删除流程。In this embodiment of the present invention, each DRB corresponds to a preset aging time. When a DRB is completed, the ANF will start timing. During the timing, if there is data transmitted on the DRB, the timing is restarted until the continuous idle time of the DRB reaches or exceeds the preset aging time, and the ANF regards the DRB as the aging DRB. The preset aging time corresponding to different DRBs may be different or the same. The aging time may be determined by the operator based on user information, and the aging time may also be based on QoS parameters (eg, packet priority, packet loss rate, delay, etc.) or based on Packet Data Unit (PDU) sessions. Level to determine. When a DRB is in an idle state (a state in which the DRB does not use the DRB to receive or transmit data), the DRB is an aging DRB, and the ANF obtains the ID of the DRB, and Initiate the DRB deletion process.

或者，当已建立的DRB均未老化时，ANF确定已建立的DRB中连续空闲时间最长的一个为目标DRB；Or, when the established DRBs are not aged, the ANF determines that the longest idle time in the established DRBs is the target DRB;
或者，ANF根据已建立的DRB对应的服务质量属性确定目标DRB。Alternatively, the ANF determines the target DRB according to the quality of service attribute corresponding to the established DRB.
本发明实施例中，当ANF确定已建立的所有DRB的连续空闲时间均未超过对应的老化时间时，ANF从已建立的所有DRB中选择老化时间最长的一个作为目标DRB，或者ANF从已建立的所有DRB中选择连续空闲时间最长的一个作为目标DRB，或者ANF根据已建立的DRB对应的服务质量属性确定目标DRB。服务质量属性(QoS属性)，可以分为保证比特率(Guaranteed Bit Rate，GBR)和非保证比特率(non-Guaranteed Bit Rate，non-GBR)两类。ANF可以根据已建立的DRB对应的QoS属性确定需要删除的目标DRB。具体的，例如，ANF可以确定QoS属性为non-GBR的DRB为需要删除的目标DRB。或者ANF根据建立DRB使用的QoS属性参数优先级确定需要删除的目标DRB，即删除优先级最低的DRB。In the embodiment of the present invention, when the ANF determines that the continuous idle time of all the established DRBs does not exceed the corresponding aging time, the ANF selects the one with the longest aging time from all the established DRBs as the target DRB, or the ANF has been One of the established DRBs selects the longest continuous idle time as the target DRB, or the ANF determines the target DRB according to the quality of service attribute corresponding to the established DRB. The quality of service attributes (QoS attributes) can be classified into Guaranteed Bit Rate (GBR) and Non-Guaranteed Bit Rate (non-GBR). The ANF may determine the target DRB to be deleted according to the QoS attribute corresponding to the established DRB. Specifically, for example, the ANF may determine that the DRB whose QoS attribute is non-GBR is the target DRB that needs to be deleted. Or the ANF determines the target DRB to be deleted according to the priority of the QoS attribute parameter used by the DRB, that is, deletes the DRB with the lowest priority.
当ANF需要建立新的DRB时，如果ANF与UE之间已建立的DRB的个数已经达到预设上限值(例如，预设上限值为8个)，无法再建立新的DRB时，此时从ANF与UE之间已经建立的DRB中确定目标DRB，则ANF获取目标DRB(待删除的DRB)的标识，触发ANF发起DRB删除流程。When the ANF needs to establish a new DRB, if the number of established DRBs between the ANF and the UE has reached the preset upper limit (for example, the preset upper limit is 8), a new DRB cannot be established. At this time, the target DRB is determined from the established DRBs between the ANF and the UE, and the ANF obtains the identifier of the target DRB (the DRB to be deleted), and triggers the ANF to initiate the DRB deletion process.
可选的，步骤601中ANF获取目标DRB的标识的方式具体可以为：Optionally, the manner in which the ANF obtains the identifier of the target DRB in step 601 may be specifically:
若第二DRB的所有业务均已经结束，则ANF获取第二DRB的标识；或者，If all services of the second DRB have ended, the ANF obtains the identifier of the second DRB; or

其中，第二DRB为ANF与UE之间已建立的DRB中的任一个。The second DRB is any one of the established DRBs between the ANF and the UE.
本发明实施例中，一个DRB可以对应一个或多个QoS规则，每个QoS规则对应一个老化时间，老化时间可以是运营商基于用户的信息来确定的，老化时 间的大小可以基于QoS参数(例如，数据包优先级、丢包率、延时等)或者基于分组数据单元(Packet Data Unit，PDU)会话级别来确定。当一个QoS规则的连续空闲时间达到或者超过对应的老化时间时，即一个QoS规则在连续的一段时间(老化时间)内没有被使用，则ANF删除该QoS规则。当一个DRB对应的所有服务质量规则都被删除时，确定该DRB为目标DRB。在一个具体场景中，在创建或者获取一个QoS规则时，ANF获取该QoS规则对应的老化时间，此时ANF开始计时，如果在老化时间内，没有使用该QoS规则处理数据，则ANF删除该QoS规则。In the embodiment of the present invention, one DRB may correspond to one or more QoS rules, and each QoS rule corresponds to an aging time, and the aging time may be determined by the operator based on user information. The size may be determined based on QoS parameters (eg, packet priority, packet loss rate, delay, etc.) or based on Packet Data Unit (PDU) session level. When the continuous idle time of a QoS rule reaches or exceeds the corresponding aging time, that is, a QoS rule is not used for a continuous period of time (aging time), the ANF deletes the QoS rule. When all the quality of service rules corresponding to a DRB are deleted, it is determined that the DRB is the target DRB. In a specific scenario, when creating or acquiring a QoS rule, the ANF obtains the aging time corresponding to the QoS rule. At this time, the ANF starts timing. If the QoS rule is not used to process data during the aging time, the ANF deletes the QoS. rule.
可选的，在执行步骤601之前，还可以执行如下步骤。Optionally, before performing step 601, the following steps may also be performed.

For example, first, the UE establishes a PDU session with the network side, and the application server node AS (Application Server) sends a downlink data packet to the user plane node UPF. Then, after receiving the downlink data packet, the UPF marks the downlink data packet according to the QoS rule. The tag data packet is obtained, the tag data packet carries the tag information (also becomes the marking information), and the UPF sends the tag data packet to the ANF. Since different tag information can indicate different DRBs, the same tag information can indicate the same DRB, ANF. Receiving the tag data packet sent by the UPF, the ANF determines whether the DRB indicated by the tag information has been established. If yes, the ANF uses the DRB transmission tag data packet indicated by the tag information to the UE; if not, the ANF establishes a new DRB and allocates a new DRB. Aging time. The tag information may be marked according to a QoS rule of the data packet. For example, the tag information may include or be used to indicate a packet priority, a packet loss rate, a delay, and the like.
