摘要

Methods, systems, and computer program products for providing fault- tolerant service interaction and mediation function in a communications network are disclosed. According to one aspect, the subject matter described herein includes a method for providing fault-tolerant service interaction and mediation capability. The method includes providing an active instance of a service capability interaction manager (SCIM) function for providing service interaction and mediation between entities that request network services and entities that provide network services in a communications network. The method also includes providing a standby instance of the SCIM function. The active instance of the SCIM function performs service interaction and mediation between the entities that request network services and the entities that provide network services. In response to failure of the active SCIM function, the standby instance of the SCIM function takes over the service interaction and mediation previously performed by the active instance of the SCIM function.
