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, need special user's (special user is meant the user with special rights) that special operational is carried out in the conversation between other users in the system usually, to increase work efficiency; The special user is when carrying out special operational, and the call scheduling information (comprising call status information and call session information etc.) that need obtain the current user who is conversing can realize current talking user's conversation is operated accordingly accurately.
At present, communication scheduling system mainly is divided into two subsystems, as shown in Figure 1, is divided into dispatch call control subsystem and schedule information processing subsystem, wherein:
The dispatch call control subsystem is used to control and handle call control signalling and medium between the caller party terminal, and the call scheduling information of caller party terminal is sent to the schedule information processing subsystem; And, the dispatching services request that the receiving scheduling information processing subsystem sends;
The schedule information processing subsystem is used to store the call scheduling information that described dispatch call control subsystem sends, and this call scheduling information is sent to dispatching desk, so that dispatching desk presents described call scheduling information; And, be used to collect the dispatching services request that dispatching desk issues, and this dispatching services request is transmitted to described dispatch call control subsystem.
At present, the 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: the dispatch call control subsystem is divided into the professional and professional two parts of Presence (presenting) of dispatch call control with dispatching services, wherein, the professional logic control function of finishing dispatch call of dispatch call control, presence service is finished the storage and the issue of the call scheduling information of dispatch call terminal; Dispatch call control AS (Application Server, application server) professional and that presence service mainly passes through in the IMS network architecture realizes, for whole system provides business support.
In the dispatching patcher as shown in Figure 1, usually pass through TCP (Transfer Control Protocol between dispatch call control subsystem and the schedule information processing subsystem, transmission control protocol) mode connects, and finishes the transmission of call information and control messages by self-defining message; Finish alternately by proprietary protocol and mechanism between schedule information processing subsystem and the dispatching desk.
Can there be following two technological deficiencies in above-mentioned dispatching patcher:
1) in the dispatch call control subsystem, dispatch call control is professional and the interface function coupling ratio is tightr, when interface message changes, need docking port message to adjust, can form the various protocols interface, thereby influence 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 be finished between dispatch call control subsystem and the schedule information processing subsystem before disposing and carry out mutual protocol interface, therefore, after disposing, do not allow the new schedule information processing subsystem of expansion in dispatching patcher, only allow to have disposed the schedule information processing subsystem and carry out internal extended, thereby be unfavorable for system extension like this, flexibility is relatively poor.

Preferably, the said method flow process also can comprise step 1003, shown in Figure 10 B:
Second schedule information after the renewal corresponding that step 1003, the described presence service subsystem of reception send with described publicly-owned service identifiers; Described first schedule information according to the described second schedule information updated stored.
In the embodiment of the invention, on the one hand, the dispatch call control subsystem is published to schedule information in the presence service subsystem, so that other subsystems obtain the corresponding business schedule information from the presence service subsystem, according to IETF and 3GPP tissue as can be known to the definition of presence service, presence service can be expanded arbitrarily, authorized business service or user can subscribe to by presence service, issue and present schedule information, therefore, the presence service subsystem can adopt various protocols interface and other subsystems to carry out alternately, be not limited in the protocol interface of certain appointment, therefore adopt technical solution of the present invention, having simplified each subsystem obtains the flow process of schedule information and has improved the efficient of obtaining schedule information, and improved the extensibility of system to a certain extent, reduce the coupling of intersystem interface, thereby improved the flexibility of system deployment; On the other hand, the schedule information after the dispatch call control subsystem will be upgraded in real time sends to the presence service subsystem, so that presence service subsystem real-time update stored scheduling information; The presence service subsystem is after having upgraded stored scheduling information, schedule information after upgrading is sent to corresponding other subsystems, so that the local stored scheduling information of other subsystem real-time update, thereby guarantee to send to the accuracy of the schedule information of other subsystems; Again on the one hand, schedule information in the embodiment of the invention is based on the XML plain text format, therefore, subsystem in the network system all can be supported the message format of this schedule information, thereby be easy to from the presence service subsystem, obtain schedule information, thereby further made things convenient for system extension, can not influence the data that each subsystem obtains to be needed separately from interface message to guarantee any expansion under the XML message format.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
