Abstract

Description

传递关键业务承载的方法及装置、电子设备及存储介质 技术领域
本申请涉及移动通信领域,例如涉及一种5G场景下传递关键业务承载的方法及装置、电子设备及存储介质。
背景技术
随着移动通信技术的发展,5G(5rd Generation,第五代)已经进入人们的视眼。在5G无线接入网(Radio Access Network,RAN)架构方面,3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)通过了CU/DU(Central Unit/Distributed Unit,集中单元/分布单元)架构方案。CU主要处理非实时的无线高层协议栈功能,而DU主要处理物理层功能。CU与DU通过F1接口完成信令和数据传输。
协议中规定,每个PDU session(PDU会话)(PDU:Packet Data Unit,分组数据单元)的生命周期内,至少要有一个服务质量流(Quality of Service Flow,Qos Flow)作为缺省的Qos Flow,并且这个Qos Flow必须是不保证比特速率(Non-Guaranteed Bit Rate,Non-GBR)类型。如果没有这样的Qos Flow,此PDU session不应该被建立/修改成功。另外,存在一种Qos Flow是携带信元附加QoS流信息(Additional QoS Flow Information),表示该Qos Flow对比PDU session中的其他Qos Flow业务会更频繁发生。只有Non-GBR类型的Qos Flow才会携带Additional QoS Flow Information信元。
以上包括的Non_GBR类型的业务和携带了Additional QoS Flow Information信元的业务被称为关键业务。基站侧应该尽量保证这样的关键业务接纳成功,在小区资源有限的情况下,如果这种关键业务建立/接纳失败,可能会导致PDU session接纳失败,会影响关键业务的连续性,影响用户体验。
