Technical field
The present invention relates to the IMS field, relate in particular to a kind of IMS OSS and method.
Background technology
Telecom business support system (OSS/BSS) is a back-up system integrated in telecom operators' operation process, that information resources are shared, mainly partly forms by chargeing, seek account, customer service, network management etc., and be a comprehensive service operation and management platform.
IMS (IP Multimedia Subsystem, IP Multimedia System) is a kind of communication network of supporting multimedia service, and it can satisfy client's novelty, diversified multimedia service demand.At present, IMS is considered to the core technology of next generation network, also is to solve mobile network and fixed network fusion, introduces the important way of differentiation business such as voice, data, the triple fusions of video.
There are the difference of essence in IMS and 2G system, and it is based on the all-IP Packet Based Network of SIP (Session Initial Protocol, initial session protocol) agreement, support the access of circuit domain and packet domain, also support the integrated services of circuit domain and packet domain simultaneously.The IMS network has following characteristics:
(1) because IMS has realized separating of operation layer and key-course, operator can dispose new business fast.Therefore, with respect to existing core net, IMS has more Added Business kind, and this just requires the IMS OSS to have the support of exploitation IMS new business, so, all need from information model design or on function and the flow process existing OSS is replenished and strengthens;
(2) IMS has increased many network elements newly, the network configuration of himself is also very complicated, as external database---HSS (Home Subscriber Server, home subscriber server) is used for unified management user's fused data, OCS (Online Charging System, Online Charging System) and PDF (Policy DecisionFunction, strategy decisive function) etc., this will cause the more network elements of OSS management;
(3) owing to support that various multimedia services are one of key characters of IMS,, support so need OSS to provide more perfect QoS to manage so guarantee that professional QoS (Quality of Service, service quality) is the big characteristics of IMS.
Therefore, These characteristics will cause the IMS OSS to be different from the OSS of existing 2G system.At present, the work of the operation support of relevant IMS still is in the exploratory stage, and existing work is broadly divided into two classes, and a class is based on the theoretic discussion that some related specifications of the 3GPP of International Standards Organization, 3GPP2 provide; Another kind of is to have carried out deep research at certain involved in IMS operation support problem, but these researchs up to now all do not form complete IMS end-to-end (from the management of a series of coherent, the orderly activity of IMS product design, the professional whole life process that generates, orders, opens, charges) operation support mechanism, can not effectively support operator carrying out smoothly based on the 3G business of IMS network.
