Customer-focused Network and Service Management Customer Self-control Page No. - 8 e.g. Customer Self-control Customer Customer control Access Nodes Personal Portal Policy Server NMS Customer changes service profiles of provisioned services. BoD, Voice Mail, Parental Care, Presence and Location, Contextaware Services etc. NMS has to monitor customer controlled network and resources User Profile Service Profile Resource IP/MPLS Billing ISP Page 8
Customer-focused Network and Service Management Traffic Management : from a customer experience perspective Problems occur with interacting services within media streams NSP introduces deep packet inspection technologies To analyze how interacting services affect each other Page No. - 9 <Case> A company is connected to Internet with 10Mbps leased line. When N people are using VoIP phone, M people access IP-TV and the performance of both service are degraded. Q1 : Who is responsible for the degradation of quality? A1: The service provider who sold VoIP and IP-TV services Q2 : Among the N VoIP and M IP-TV channels, which one and how the quality is degraded? A2:??? Q3 : If some packets are dropped by priority control, how can the service provider explain it to customers? 100Mbps Packet drop, delay, QoS degradation Page 9
Customer-focused Network and Service Management Current Page No. - 10 Service order Order decomposition Siloed OSSs design, resource allocation, activation design, resource allocation, activation design, resource Customer allocation, activation Center Request for recovery/reconfiguration Current service provisioning process Reactive and slow-working process Service configuration NOK End-to-end test OK Customer DB Page 10
Customer-focused Network and Service Management Future Page No. - 11 Customer Center Service define Integrated NMS Service order Future service provisioning process Real-time An Integrated NMS manages all physical and logical resources Base on the resource information, Service is defined according to the contracted QoS and rate NMS validates the network capability, and configure an end-to-end connection. PBNM can reduce human intervention to design, allocate resources and activate equipments. design, resource allocation, activation End-to-end Network View Network Configuration Customer test Customer DB Page 11
