- CU-CP Centralised Unit-Control Plane
- CU-UP Centralised Unit-User Plane
- DU distributed Unit
- the radio access network controller when requesting the radio access network controller to delete a subscription, it also carries a deletion mark corresponding to the subscription that needs to be deleted.
- This deletion mark can be understood as a forced deletion mark, that is, informing the radio access network controller of the subscription.
- the deletion level is the highest level, so that the radio access network controller can respond to subscription deletion in a timely manner.
- the first message may be a subscription deletion request (ie, RIC Subscription Delete Required) message sent by the access network device.
- each subscription requested to be deleted in the first message may correspond to a deletion identifier; or multiple subscriptions may share a deletion identifier, that is, multiple subscriptions requested to be deleted in the first message may correspond to the same deletion identifier.
- a deletion identifier When the radio access network controller obtains the deletion identifier, it can know that the subscriptions requested to be deleted in the first message all have a forced deletion identifier.
- step S101 the method further includes:
- the first condition includes one of the following:
- the radio access network controller can respond to the first message in a timely manner, the radio access network controller and the access network device perform a subscription deletion process (ie, RIC Subscription Delete procedure), and the radio access network control
- the radio access network controller will feed back a second message to the access network device.
- the second message is used to instruct the deletion of the first subscription among the at least one subscription indicated in the first message, because when deleting the subscription, the radio access network controller
- the access network device can only delete one subscription at a time. That is to say, the wireless access network controller can only delete one subscription by sending the second message once. If multiple subscriptions need to be deleted, the wireless access network controller needs to send it multiple times. Second news.
- the second message may be a subscription deletion request (ie, RIC Subscription Delete Request) message sent by the radio access network controller.
- a subscription deletion request ie, RIC Subscription Delete Request
- the access network device actively deletes at least one subscription requested in the first message.
- the access network device receives the second message corresponding to the subscription only after the access network device actively deletes a certain subscription, since the subscription no longer exists on the access network device side, it needs to feed back the corresponding message. Notify the radio access network controller of its own situation.
- at least one embodiment of the present disclosure also includes:
- a subscription deletion failure message is fed back to the radio access network controller, where the subscription deletion failure message is used to indicate that the failure reason is that the subscription does not exist.
- the method further includes: sending a subscription to the radio access network controller Update message, the subscription update message carries identification information of all subscriptions existing in the access network device.
- the access network device needs to notify the wireless access network controller of all existing subscriptions on the access network device to ensure synchronization of existing subscriptions between the two.
- the access network device starts the timer, whether the timer times out or the requested subscription is deleted during operation, the timer will be canceled.
- the subscription deletion process initiated by the E2 node is shown in Figure 2.
- the forced deletion identifier can be carried in the subscription deletion request message to support the local forced release of the subscription by the E2 node. Specifically, it includes:
- Step 101 establish one or more RIC Subscriptions between Near-RT RIC and E2 node;
- RIC request index for example, RIC Request ID
- RAN function index for example, RAN Function ID
- Step 102 The E2 node discovers that one or more RIC Subscriptions need to be deleted during operation;
- Step 103 the E2 node initiates a RIC Subscription Delete Required message
- the RIC Subscription Delete Required message contains the RIC that needs to be deleted List of Subscriptions (List of RIC Subscriptions To Be Removed), which contains one or more subscriptions that need to be deleted, identified by RIC Request ID and RAN Function ID. If there is a RIC Subscription that needs to be forcibly deleted, the E2 node will also carry a compulsory flag (Compulsory Flag).
- Near-RT RIC receives the RIC Subscription Delete Required message and has the following two processing branches for each RIC Subscription contained in the list:
- Step 104 Near-RT RIC decision-making
- Step 105 When the Near-RT RIC decision allows deletion of the subscription, initiate the RIC Subscription Delete procedure (RIC Subscription Delete procedure).
- Step 106 After the E2 node sends the RIC Subscription Delete Required message, it will start the local timer T RICSUBdelete and wait for Near-RT RIC feedback.
- Step 107 After receiving the RIC Subscription Delete Required message, Near-RT RIC immediately decides to initiate the RIC Subscription Delete process.
- Step 108 Near-RT RIC releases the subscription-related resources and initiates the RIC Subscription Delete procedure.
- This process carries the RIC Request ID and RAN Function ID to inform the E2 node of the RIC Subscription that needs to be deleted.
- Step 109 After the timer times out, the E2 node locally releases the RIC Subscription.
- Step 110 After receiving the RIC Subscription Delete Request message sent by the Near-RT RIC or deleting the subscription locally, the E2 node cancels the timer T RICSUBdelete .
- Scenario 1 After the E2 node deletes the subscription locally after the timer expires, it receives a RIC Subscription Delete Request message sent by Near-RT RIC for the subscription. Since the subscription no longer exists locally on the E2 node, a RIC Subscription Delete Failure message will be fed back, carrying the reason (cause). Identifies the RIC request index unknown (RIC Request ID unknown). At this time, Near-RT RIC should consider that the subscription has been deleted locally on the E2 node, and the subscription contexts of both parties are synchronized.
- the RIC SUBSCRIPTION DELETE REQUIRED message contains a list of RIC Subscriptions that the E2 node requests to delete, which includes one or more RIC subscriptions. Each item in the list specifies a RIC subscription to be deleted and carries the reason for deletion.
- Compulsory Flag is applied to a single RIC Subscription in the List, which can realize different configurations of different RIC Subscriptions in the List of RIC Subscriptions To Be Removed, and you can decide whether to force deletion separately. This method is more flexible.
- Scenario 2 The E2 node actively reports updates after deleting the subscription locally.
- the E2 node if it locally deletes subscriptions or other failures cause some subscriptions to be deleted, it will actively send a RIC Subscription Update message.
- This message contains the RIC subscriptions that currently exist on the E2 node, informing Near -RT RIC current subscription status.
- Near-RT RIC When Near-RT RIC receives this message, it can process Near-RT RIC's internal subscription based on the information provided by the E2 node and align the subscription contexts of both parties. This avoids local deletion of subscriptions on the E2 node, loss of context information due to Near-RT RIC failure, etc., which will cause inconsistent RIC subscription status between both parties, resulting in protocol errors such as Near-RT RIC being unable to learn the E2 node subscription status, thus affecting data collection and optimization. Control, etc., problems that reduce system operating efficiency arise.
- the embodiment of the present disclosure proposes a support for the problem in the related technology that the E2 node, as the resource provider of the subscription, lacks forced deletion of subscriptions, causing overload or failure of the E2 node and further aggravating the failure to release resources in time.
- the method of forcibly releasing subscriptions and resources locally on the E2 node can effectively reduce possible failures caused by base station overload, configuration errors, etc.

Abstract

Description
相关申请的交叉引用
本公开主张对2022年07月28日在中国提交的申请号为No.202210898523.7的中国专利申请的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,特别涉及一种信息传输方法、装置、接入网设备及无线接入网控制器。
相关技术中的E2接口连接的无线接入网(Radio Access Network,RAN)侧网络功能实体(可以称为E2节点,其为基站侧节点)发起的订阅删除请求过程,必须依赖于近实时无线接入网控制器(Near Real Time RAN Intelligent Controller,Near-RT RIC)的决定。而Near-RT RIC仅将E2节点试图删除订阅的请求作为建议,并不必然导致订阅删除过程。当E2节点作为订阅资源提供方,发生过载或故障时,亟需删除一个或多个订阅时,必须等待Near-RT RIC的决策,且有可能被Near-RT RIC拒绝该删除请求。因而E2节点无法及时释放资源,造成进一步的过载或故障,使得节点不稳定性增加。
若E2节点强行启动复位(Reset)过程,则将直接删除所有RIC订阅(Subscriptions)并释放资源,不仅会影响到原本请求删除的订阅,还会删除其他关键的订阅,造成资源不必要的释放。Near-RT RIC则需完全重新建立所有订阅才可恢复,增加恢复时间和处理时延。
在E2节点在过载、故障等必要的时候,因Near-RT RIC的决策拒绝订阅删除请求,导致E2节点设备无法稳定工作是亟待解决的问题。

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本公开的实施例,例如除了在这里图示或描述的那些以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤
或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
在本公开实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的信息传输方法、装置、接入网设备及无线接入网控制器可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation,5G)移动通信新空口(New Radio,NR)技术的系统(以下均简称为5G NR系统),所述领域技术人员可以了解,5G NR系统仅为示例,不为限制。
本公开实施例提供了信息传输方法、装置、接入网设备及无线接入网控制器,以保证E2节点设备的稳定工作。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施例可以相互参见,重复之处不再赘述。
如图1所示,本公开实施例提供一种信息传输方法,由接入网设备执行,包括:
步骤S101,向无线接入网控制器发送第一消息,所述第一消息用于请求删除至少一个订阅、且所述第一消息中携带所述至少一个订阅对应的删除标识。
需要说明的是,本公开实施例中的无线接入网控制器可以包括近实时无线接入网智能控制器(Near-RT RIC)。该接入网设备可以理解为是E2接口连接的RAN侧网络功能实体(可以称为E2节点),例如可以为4G基站eNB(Evolved Node B,演进型B节点)、5G基站gNB(NR Node B,新空口B
节点),也可以是集中式单元控制面(Centralised Unit-Control Plane,CU-CP),集中式单元用户面(Centralised Unit-User Plane,CU-UP)或者分布式单元(Distributed Unit,DU),或者CU-CP和CU-UP的聚合形式等。
本公开实施例中在向无线接入网控制器请求删除订阅时,同时还携带需要删除订阅对应的删除标记,该删除标记可以理解为是强制删除标记,即告知无线接入网控制器该订阅的删除等级为最高级,以使得无线接入网控制器及时的响应订阅删除。可选地,该第一消息可以为接入网设备发送的订阅删除请求(即RIC Subscription Delete Required)消息。
进一步地,在具体传输时,该第一消息中请求删除的每一个订阅可以分别对应一个删除标识;也可以是多个订阅共用一个删除标识,即第一消息中请求删除的多个订阅共同对应一个删除标识,当无线接入网控制器获取到该删除标识时,便可以知道第一消息中请求删除的订阅均具有强制删除标识。
可选地,在步骤S101之后,所述方法,还包括:
启动定时器;
在满足第一条件的情况下,删除第一订阅;
其中,所述第一条件包括以下一项:
A11、在所述定时器超时前收到所述无线接入网控制器反馈的第二消息;
可选地,若无线接入网控制器能够及时的响应该第一消息,无线接入网控制器和接入网设备之间进行订阅删除过程(即RIC Subscription Delete procedure),无线接入网控制器会向接入网设备反馈第二消息,该第二消息用于指示删除所述第一消息中指示的至少一个订阅中的第一订阅,因在进行订阅删除时,无线接入网控制器和接入网设备一次只能删除一个订阅,也就是说无线接入网控制器发一次第二消息只能删除一个订阅,若需要删除多个订阅,则无线接入网控制器需要发送多次第二消息。
可选地,该第二消息可以为无线接入网控制器发送的订阅删除请求(即RIC Subscription Delete Request)消息。
A12、在所述定时器超时的情况下未收到所述无线接入网控制器反馈的第二消息;
可选地,若定时器超时,无线接入网控制器也未能够响应该第一消息,
即无线接入网控制器也未能够向接入网设备发送第二消息,则接入网设备主动删除第一消息中所请求的至少一个订阅。
可选地,因接入网设备主动删除某一订阅之后,若接入网设备才接收到该订阅对应的第二消息,因接入网设备侧已经不存在该订阅,其需要反馈相应的消息告知无线接入网控制器自身的情况,具体地,本公开的至少一个实施例中,还包括:
若接收到所述无线接入网控制器发送的第二消息,反馈订阅删除失败消息给所述无线接入网控制器,所述订阅删除失败消息用于指示失败原因为订阅不存在。
可选地,因接入网设备主动删除某一订阅,为了保证接入网设备与无线接入网控制器之间的订阅的同步,本公开的至少一个实施例中,在所述定时器超时的情况下未收到所述无线接入网控制器反馈的第二消息的情况下,在所述删除第一订阅之后,所述方法,还包括:向所述无线接入网控制器发送订阅更新消息,所述订阅更新消息中携带接入网设备存在的所有订阅的标识信息。
也就是说,接入网设备在主动删除订阅后,需要将自身还存在的所有订阅都告知无线接入网控制器,以保证二者所存在订阅的同步。
还需要说明的是,当接入网设备在启动定时器后,不管是在定时器超时还是运行期间进行所请求订阅的删除后,均会取消定时器。
下面以E2节点与Near-RT RIC的通信为例,对本公开的具体应用进行举例说明如下。
情况一、E2节点发起的订阅删除流程如图2所示,可在订阅删除请求消息中携带强制删除标识来支持E2节点本地强制释放订阅,具体包括:
步骤101,Near-RT RIC和E2节点之间建立一个或多个RIC Subscriptions;
需要说明的是,不同的订阅通常可以通过RIC请求索引(例如,RIC Request ID)和/或RAN功能索引(RAN Function ID)等标识。
步骤102,E2节点在运行时发现需要删除一个或多个RIC Subscriptions;
步骤103,E2节点发起RIC Subscription Delete Required消息;
该RIC Subscription Delete Required消息中包含需要删除的RIC
Subscriptions的列表(List of RIC Subscriptions To Be Removed),其中包含了需要删除的一个或多个订阅,使用RIC Request ID,RAN Function ID标识。如果其中有RIC Subscription需要强制删除,则E2节点将同时携带强制删除标识(Compulsory Flag)。
Near-RT RIC接收到RIC Subscription Delete Required消息,对列表(List)中包含的每个RIC Subscription有如下两个处理分支:
分支一、当未设置Compulsory Flag(该信息元素(Information Element,IE)不存在,遵从原本的过程)
步骤104,Near-RT RIC决策;
步骤105,在Near-RT RIC决策允许删除订阅时,发起RIC订阅删除过程(RIC Subscription Delete procedure)。
分支二、当Compulsory Flag存在且设置为真(true)
步骤106,E2节点发送RIC Subscription Delete Required消息后,将启动本地定时器TRICSUBdelete等待Near-RT RIC反馈。
此种情况下,具有如下两个处理分支:
分支一、当Near-RT RIC在定时器TRICSUBdelete运行时间内及时反馈
步骤107,Near-RT RIC接收到RIC Subscription Delete Required消息后,立即决定发起RIC Subscription Delete过程。
步骤108,Near-RT RIC释放该订阅相关资源,发起RIC Subscription Delete procedure,该过程携带RIC Request ID和RAN Function ID告知E2节点需删除的RIC Subscription。
分支二、定时器TRICSUBdelete超时
步骤109,E2节点在定时器超时后,本地释放该RIC Subscription。
步骤110,E2节点接收到Near-RT RIC发送的RIC Subscription Delete Request消息或者本地删除订阅后,取消定时器TRICSUBdelete。
进一步地,E2节点执行本地删除后有两种处理情况:
情况一、E2节点在计时器结束采取本地删除订阅后,针对该订阅收到了Near-RT RIC发送的RIC Subscription Delete Request消息。由于E2节点本地已不存在该订阅,将反馈RIC Subscription Delete Failure消息,携带原因(cause)
标识RIC请求索引未知(RIC Request ID unknown)。此时Near-RT RIC应认为E2节点本地已删除该订阅,双方订阅上下文同步。
情况二、E2节点始终未收到Near-RT RIC发送的针对该订阅的任何订阅删除消息,表明Near-RT RIC拒绝该删除请求、故障原因未能收到或未能处理该请求,此时E2节点和Near-RT RIC的订阅上下文未同步。
进一步地,RIC SUBSCRIPTION DELETE REQUIRED消息中包含E2节点请求删除的RIC Subscription列表,即可包括一个或多个RIC订阅,列表的每一项指明了一个待删除的RIC订阅并携带需要删除的原因。
在该列表项中添加一个可选(Optional)IE:Compulsory Flag。当E2节点认为一个或多个RIC订阅需要强制删除时,将携带该flag指示。若不需要强制删除,E2节点可不携带该flag,遵从原有机制即可。RIC SUBSCRIPTION DELETE REQUIRED消息内容的一个种格式如表1所示:
表1支持强制释放的RIC SUBSCRIPTION DELETE REQUIRED消息内容
此处Compulsory Flag应用于List中单个RIC Subscription,可实现List of RIC Subscriptions To Be Removed中不同RIC Subscription有不同配置,即可分别决定是否需要强制删除,此种方式较为灵活。
例如,若对所有RIC Subscription进行整体标识处理,则可使用表2中的方式,即表明对List of RIC Subscriptions To Be Removed中所有RIC Subscription,都需要强制删除。此种方式相对上述方式,可以一次性标识全部RIC Subscriptions。
表2整体标识强制删除的RIC SUBSCRIPTION DELETE REQUIRED消息内容
情况二、E2节点本地删除订阅后主动上报更新
如图3所示,E2节点发生本地删除订阅或其他故障导致某些订阅删除,将主动发送RIC订阅更新(RIC Subscription Update)消息,该消息中包含目前在E2节点仍存在的RIC订阅,告知Near-RT RIC目前订阅情况。
Near-RT RIC接收到该消息,可根据E2节点提供的信息对Near-RT RIC内部订阅进行处理,对齐双方的订阅上下文。以此避免E2节点本地删除订阅、Near-RT RIC故障导致上下文信息丢失等,将造成双方的RIC订阅状态不一致,产生协议错误如Near-RT RIC无法获知E2节点订阅情况,从而影响数据收集及优化控制等,降低系统运行效率的问题出现。
需要说明的是,本公开实施例针对相关技术中E2节点作为订阅的资源提供方因缺乏强制删除订阅,导致E2节点过载或故障问题因无法及时释放资源而进一步加重的问题,提出了一种支持E2节点本地强制释放订阅及资源的方法,可有效减少基站过载、配置错误等可能导致的故障。
本公开实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时

如图9所示,本公开实施例提供一种信息传输方法,由接入网设备执行,包括:
步骤S901,向无线接入网控制器发送订阅更新消息,所述订阅更新消息中携带接入网设备的目标订阅的标识信息。
需要说明的是,本公开实施例中的无线接入网控制器可以包括近实时无线接入网智能控制器(Near-RT RIC)。该接入网设备例如可以为基站,也可以为属于接入网侧的E2节点。

可选地,该步骤S901的实现过程包括以下一项:
B11、在接入网设备存在本地删除订阅或订阅丢失的情况下,向所述无线接入网控制器发送订阅更新消息;
需要说明的是,当接入网设备主动删除订阅(该主动删除订阅的过程参见上述实施例的实现过程,在此不再赘述)或者订阅丢失(例如,接入网设备发生故障导致重新启动后丢失了一部分订阅),主动向无线接入网控制器发送订阅更新消息;可以理解的是,此种情况下,可以理解为接入网设备一旦执行了主动删除订阅或者是知道了自己丢失了订阅,则立即向无线接入网控制器发送订阅更新消息。
可选地,此种情况下,该目标订阅为所述接入网设备存在的所有订阅。
B12、接收所述无线接入网控制器发送的订阅查询(即RIC Subscription Query)消息,根据所述订阅查询消息,向所述无线接入网控制器发送订阅更新消息;
可选地,此种情况下是无线接入网控制器向接入网设备进行订阅的查询,接入网设备只有在接收到订阅查询消息后才向无线接入网控制器发送订阅更新消息。

例如,无线接入网控制器在向接入网设备查询订阅时,可以在订阅查询消息中携带想要查询的订阅的标识信息,也可以什么都不携带;在订阅查询消息中携带无线接入网控制器想要查询的订阅的标识信息的情况下,接入网设备需要针对无线接入网控制器查询的特定订阅进行反馈,例如反馈无线接入网控制器查询的特定订阅是否存在;在订阅查询消息中不携带任何订阅的标识信息的情况下,可以理解为无线接入网控制器想要查询接入网设备侧的
所有订阅,接入网设备需要反馈自身存在的所有订阅给无线接入网控制器。
下面以E2节点与Near-RT RIC的通信为例,对本公开的具体应用进行举例说明如下。
情况一、E2节点主动上报方式
E2节点发生本地删除订阅或其他故障导致某些订阅删除,将主动发送RIC订阅更新(RIC Subscription Update)消息,该消息中包含目前在E2节点仍存在的RIC订阅,告知Near-RT RIC目前订阅情况。
Near-RT RIC接收到该消息,可根据E2节点提供的信息对Near-RT RIC内部订阅进行处理,对齐双方的订阅上下文。
情况二、Near-RT RIC查询的方式
Near-RT RIC在运行过程中,发现E2节点上报的信息缺失,例如,针对某个订阅始终未能收到上报消息,则可发起RIC Subscription Query过程查询E2节点的订阅情况,具体过程如图10所示:
步骤201,Near-RT RIC发送RIC Subscription Query消息给E2节点;
该消息中可包含:a)查询所有E2节点处的订阅,b)查询一个或多个特定订阅的状态信息(部分订阅);
步骤202,E2节点接收到RIC Subscription Query消息后,将根据Near-RT RIC的查询需求,对照本地已有的订阅,并反馈RIC Subscription Update消息给Near-RT RIC,告知查询结果。
进一步地,当Near-RT RIC查询所有订阅时,E2节点在RIC Subscription Update消息中包含本地现存订阅的完整列表;当Near-RT RIC查询部分订阅时,E2节点根据RIC提供的订阅进行反馈,可包含本地现存的订阅、未知的订阅(即本地不存在的订阅)等。
进一步地,上述RIC订阅同步过程中,RIC Subscription Query消息可定义为如表3中的格式,可选地包含Near-RT RIC想要查询的RIC Subscription列表。当List of Queried RIC Subscriptions不存在时,则表明Near-RT RIC查询当前在E2节点的所有订阅。
表3 RIC Subscription Query消息内容
可选地,Near-RT RIC向E2节点请求的RIC订阅的最大数量为1024。
进一步地,上述RIC同步过程,RIC Subscription Update消息可定义为如表4中的格式,其中List of Retained RIC Subscriptions和List of Unknown RIC Subscriptions都为可选项(Range从0开始)。
1、当E2节点主动上报订阅更新时,将包含List of Retained RIC Subscriptions,为E2节点处目前留有的所有RIC Subscriptions,每个订阅使用RIC Request ID和RAN Function ID标识。
2、当Near-RT RIC查询E2节点处的订阅时:
如果RIC Subscription Query消息中List of Queried RIC Subscriptions不存在,则E2节点需要反馈当前所有现存订阅,应包含List of Retained RIC Subscriptions;
如果RIC Subscription Query消息中携带了List of Queried RIC Subscriptions,E2节点按照该列表中订阅标识,分别反馈每个订阅的情况:如果该订阅仍存在,则将(RIC Request ID+RAN Function ID)放在List of Retained RIC Subscriptions中,如果该订阅不存在,则将(RIC Request ID+RAN Function ID)放在List of Unknown RIC Subscriptions中。
表4 RIC Subscription Update消息内容
可选地,E2节点向Near-RT RIC反馈的RIC订阅的最大数量为1024。
综上可知,本公开实施例针对E2节点和Near-RT RIC双发订阅上下文无法对齐的问题提出了一种订阅同步方式,可更新双方的订阅情况,提升Near-RT RIC数据收集和控制优化的效率,降低因信息不同步而无效等待造成的处理时延,提升系统稳定性和运行效率。
