SLA HANDLING IN NETWORK SLICES

Embodiments herein relate to a method performed by a RAN node (12), for managing communication on a first network slice in a communications network (1). The communications network (1) comprises partitioned sets of functionalities. A first set of functionalities belongs to the first network slice. The first set of functionalities is at least 5 partly separated from another set of functionalities out of a total set of functionalities in the communications network (1). The RAN node (12) receives, from a CN node (16), information regarding requested resources for a first network slice identified by a network slice identifier. The RAN node (12) determines that the received information does not correspond to a Service Level Agreement (SLA) for the first network slice. 本文的实施例涉及由RAN节点(12)执行的用于管理通信网络(1)中第一网络切片上的通信的方法。通信网络(1)包括分区的功能集。第一功能集属于第一网络切片。第一功能集至少部分地与通信网络(1)中全部功能集中的另一功能集相分离。RAN节点(12)从CN节点(16)接收关于由网络切片标识符识别的第一网络切片的请求资源的信息。RAN节点(12)确定接收到的信息与第一网络切片的服务等级协议(SLA)不对应。
