Embodiment
Solution for embodiment of the invention mainly detects spreading parameter in the ring-back tone detection event of bag by the such as call establishment sound of the detection event in H.248 protocol package, can convenient, fast realization to the detection of called subscriber condition, reporting functions.
As shown in Figure 1, one embodiment of the invention proposes a kind of method of NGN network user's status report, comprising:
Step S101, gateway receives the Indication message of this gateway of instruction detection called subscriber condition that Softswitch sends, and Indication message carries H.248 protocol package and detects event;
The present embodiment method running environment relates to the soft switch as control network element (i.e. Softswitch in the present embodiment) in NGN network and connects the gateway of network element as media, cannot use after detecting User Status for prior art gateway standard H.248 agreement carry out the feature that reports, the present embodiment, by expanding H.248 agreement, achieves a kind of method in NGN real-time performance gateway report of user state.
In the present embodiment, gateway is called subscriber place gateway, in the present embodiment, when needing to broadcast ring-back tone to calling subscriber in setting up voice call and calling out, called subscriber condition is detected by the gateway at Softswitch instruction called subscriber place, if called subscriber is in idle condition, then indicates controlled tone playing equipment to broadcast ring-back tone to calling subscriber by Softswitch or broadcast the color bell sound etc. of called subscriber's customization; If called subscriber is in talking state, then put the suggestion voice such as busy tone or called subscriber busy to calling subscriber.
In H.248 standard agreement, different business uses different protocol package to realize, and detects bag be described in the present embodiment for the call establishment sound in H.248 protocol package.H.248 the protocol definition of standard call establishment sound detects bag (cd bag), the various signal tones needed for can detecting in the call establishments such as busy tone, ring-back tone, stand by tone.
The present embodiment is before broadcasting ring-back tone to calling subscriber, Softswitch sends Indication message to gateway, and the ring-back tone that the call establishment sound carrying H.248 protocol definition in Indication message detects bag detects event, detect called subscriber condition to indicate gateway.
Step S102, detects called subscriber condition according to Indication message;
Step S103, the spreading parameter be carried at by the called subscriber condition detected in H.248 protocol package detection event reports Softswitch by response message, so as Softswitch according to called subscriber condition indicate controlled tone playing equipment for calling subscriber broadcasts corresponding signal tone.
In above-mentioned steps S102 and step S103, the Indication message that called subscriber place gateway sends according to Softswitch detects called subscriber condition, and the called subscriber condition detected is reported Softswitch.In the present embodiment, called subscriber condition comprises: non-calling user busy condition, talking state, idle condition and/or error condition etc., and wherein, non-calling user busy condition comprises: off hook state, user dialing state, listen the state such as ring-back tone and busy tone.
The present embodiment realizes reporting of called subscriber condition information by the mode expanding H.248 agreement, bag is detected for call establishment sound, be specially: use standard H.248 agreement call establishment sound detect bag (cd bag), by detecting spreading parameter (cd/rt{substate=x}) in ring-back tone event (cd/rt) at cd bag, by gateway, the User Status detected, the spreading parameter be carried in the ring-back tone detection event of sound detection bag reports Softswitch by response message.Wherein, cd is the H.248 protocol call process of establishing sound detection bag of standard; Rt is that the signal tone of the call establishment bag of standard detects event; Substate is the present embodiment spreading parameter, for identifying called subscriber condition; " x " is parameter value, different parameter values represents different User Status, such as: non-calling user busy condition, 1 can be represented with 0 and represent talking state, 2 and represent idle condition, 3 and represent error condition etc., parameter value includes but not limited to above-named several state value, and parameter value can increase in order to the more how possible called subscriber condition of mark according to different needs.
When Softswitch receives the called subscriber condition that gateway reports, Softswitch according to different called subscriber conditions indicate controlled tone playing equipment for calling subscriber broadcasts corresponding signal tone.In the present embodiment, controlled tone playing equipment comprises media server or called subscriber's gateway or other gateways; Wherein, signal tone comprises: color bell sound, busy tone and/or stand by tone etc.Such as: called subscriber is Idle state, then put color bell sound to calling subscriber; Off-hook state, then put busy tone to user; Voice call state, then put the verbal announcements such as " user that you dial does, and please dials after a while again " or " user that you dial converses, and please not want on-hook " to user.
The present embodiment utilizes existing NGN network-based control framework and H.248 protocol package can the feature of flexible expansion, by detecting spreading parameter in the ring-back tone detection event of bag at H.248 protocol package such as call establishment sound, can convenient, fast realization to the detection of called subscriber condition and reporting functions; Meanwhile, the method has broad applicability, is not only applicable to Ring Back Tone service, for likely needing the application scenarios detecting User Status, all can use the method.The method, when extension standards call establishment sound H.248 detects the parameter of bag, only needs a new expansion parameter, makes full use of the feature that different parameter values can represent different User Status, cover all possible User Status.
As shown in Figure 2, one embodiment of the invention proposes a kind of gateway of NGN network user's status report, comprising: Indication message receiver module 201, User Status detection module 202 and state parameter reporting module 203, wherein:
