Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of issue of service dispatching information, the method and system of obtaining.
Background technology
At present, in dispatching communication system, conventionally need special user's (special user refers to the user with special rights) to carry out special operational to the call between other users in system, to increase work efficiency; Special user is when carrying out special operational, and the call scheduling information (comprising call status information and call session information etc.) that need to obtain the current user who is conversing can realize accurately current talking user's call is operated accordingly.
At present, communication scheduling system is mainly divided into two subsystems, as shown in Figure 1, is divided into dispatch call control subsystem and schedule information processing subsystem, wherein:
Dispatch call control subsystem, for controlling and process call control signalling and the media between caller party terminal, and sends to schedule information processing subsystem by the call scheduling information of caller party terminal; And, the dispatching services request that receiving scheduling information processing subsystem sends;
Schedule information processing subsystem, the call scheduling information sending for storing described dispatch call control subsystem, and this call scheduling information is sent to dispatching desk, so that dispatching desk presents described call scheduling information; And, the dispatching services request issuing for collecting dispatching desk, and this dispatching services request is transmitted to described dispatch call control subsystem.
At present, dispatch call control subsystem mainly adopts IMS (IP Multimedia Subsystem, IP Multimedia System) network architecture, the IMS network architecture is as shown in Figure 2: dispatch call control subsystem is divided into dispatch call service control and Presence (presenting) business two parts by dispatching services, wherein, dispatch call service control completes the logic control function of dispatch call, and presence service completes storage and the issue of the call scheduling information of dispatch call terminal; Dispatch call service control and presence service are mainly realized by the AS (Application Server, application server) in the IMS network architecture, for whole system provides business support.
In dispatching patcher as shown in Figure 1, between dispatch call control subsystem and schedule information processing subsystem, conventionally pass through TCP (Transfer Control Protocol, transmission control protocol) mode connects, and completes the transmission of call information and control message by self-defining message; Between schedule information processing subsystem and dispatching desk, by proprietary protocol and mechanism, complete alternately.
Can there are following two technological deficiencies in above-mentioned dispatching patcher:
1) in dispatch call control subsystem, dispatch call service control and interface function coupling ratio are tightr, when interface message changes, need docking port message to adjust, can form various protocols interface, thereby affect the mutual of dispatch call control subsystem and other subsystems, be unfavorable for system maintenance.
2) dispatch call control subsystem and schedule information processing subsystem just must complete between dispatch call control subsystem and schedule information processing subsystem and carry out mutual protocol interface before disposing, therefore, after disposing, do not allow to expand new schedule information processing subsystem in dispatching patcher, only allow to have disposed schedule information processing subsystem and carry out internal extended, thereby be unfavorable for like this system extension, flexibility is poor.
