Description
Technical field
The present invention relates to the communications field, relate more specifically to basic service addition service and realize system and method.
Background technology
The basic service addition service implementation method of conventional switch realizes by revising switch software release.Business demand is by operator or the definition of telecommunication standardization tissue, and the equipment supplier increases new business by edition upgrading.
Multimedia service carrying content comprises common speech, video and other alternative data medium.Basic service under the IMS network environment mainly comprises: point-to-point speech business and point-to-point video traffic.Supplementary service under the IMS network environment mainly comprises: calling number identification show (CLIP), calling number identification restriction (CLIR), by the identification of consecutive numbers sign indicating number show (COLP), unconditioned call connection (CFU), call forwarding on busy (CFB), no-answer call connection (CFNRy), the unreachable Call Forwarding of user (CFNRc), Call Waiting (CW), call out keep (HOLD), MPTY (MPTY), and operator's control user conversation latching service (ODB) wait business.
The business that IMS realizes should comprise all business demands that the user proposes, and also comprises the traffic criteria of telecommunications industry definition, has comprised the multimedia communication ability.
Along with the IMS development of internet technology, because access on the IMS network architecture, control and service detach at Access Layer, can insert various access waies such as fixing, mobile, professional and access way has nothing to do, and makes the service implementation method of IMS network that very big variation arranged.
Traditional switch is realized the basic service addition service logic by increase service logic in the switch version.Since manufacturing firm's difference of switch, same business, and the service logic that each producer realizes can not guarantee unanimity.Mobile subscriber's switch and fixed-line subscriber switch are more inequality.This has just caused different switch versions to give user's experience different, has also caused the waste of exploitation, has caused waste for device fabrication cost and maintenance cost.
In correlation technique, same version is difficult to support fixing, the required business function of mobile subscriber.Correlation technique can't accomplish that different business is triggered to different application servers carries out function.And correlation technique also can't be supported the business support to newly-increased protocol terminal.Newly-increased a kind of terminal just must be changed the switch version, and upgrading switch version is stable unfavorable to system.In addition, correlation technique also can't realize coming by terminal interface functions such as custom service.
