s1ap QoS Dataset

The S1 Application Protocol (s1ap) provides signalling between E-UTRAN and Evolved Packed Core (EPC). Attributes like QCI, allocation retention priority, pre-emption vulnerability function are present in s1ap messages. During E-Ultran Radio Access Bearer (E-RAB) setup or modification, packets includes necessary QoS parameters. These packets are sent by the Mobillity Management Entity (MME) and used by the eNodeB to assign resources for one or several E-RABs. Initially data has been gathered from below sources in the form of packets. These packets are inspected through Wireshark. Through Wireshark’s powerful expressions, filters, and column selectors, the fields are exported to csv format.

S1应用协议（S1 Application Protocol，S1AP）为演进通用陆地无线接入网（E-UTRAN）与演进分组核心网（Evolved Packet Core，EPC）之间提供信令支持。S1AP消息中包含QoS类标识符（QoS Class Identifier，QCI）、分配保留优先级（Allocation Retention Priority）、抢占脆弱性功能等属性。在E-UTRAN无线接入承载（Evolved Universal Terrestrial Radio Access Bearer，E-RAB）的建立或修改过程中，相关数据包会携带必要的服务质量（Quality of Service，QoS）参数。此类数据包由移动性管理实体（Mobility Management Entity，MME）发送，供演进型节点B（eNodeB）为一个或多个E-RAB分配资源。本数据集初始以数据包形式从以下来源采集：所有数据包均通过Wireshark进行解析；借助Wireshark强大的表达式、过滤器与列选择器功能，可将指定字段导出为逗号分隔值（Comma-Separated Values，CSV）格式。数据来源包括：Wireshark捕获文件，以及ng4t.com/wireshark.html、pcapr.net/iphone6_volte_limited.pcap.html。
