The method down sends strategy of digit reception in procedure for releasing a call instead of down sending strategy of digit reception in procedure for establishing a call. The said improvement reduces user's call loss in calling procedure so as to raise switching success rate. The invention produces obvious effect in network environment of network in poor quality especially.
Description
Technical field
The present invention relates to call technology, refer to a kind of method that improves jointing-success-rate of calling especially.
Background technology
In recent years, along with the breakthrough of science and technology and the develop rapidly of Internet service, people become integration requirement to data, image and voice by voice gradually to the demand of communication service, traditional communication network more and more can not satisfy the growing communication requirement of people, needs new network that abundant voice, data, image and multimedia service is provided.At this, only (Next GenerationNetwork NGN) introduces typical call flow in the network for example with next generation network.Fig. 1 be with IP be the carrying the NGN network in call flow.In call flow as shown in Figure 1, (Media Gateway Control Protocol, MGCP), access device adopts IAD, and (Access Gateway AG) describes for example to use MGCP.What the MGCP agreement adopted is text protocol, and protocol message is divided into order and response, and each order all needs the recipient to return response in this agreement.As shown in Figure 1, concrete calling procedure is as follows:
Step 101: calling subscriber's off-hook.
Step 102～103: after caller AG detects calling subscriber's off-hook, send a notification message (NTFY), carry off-hook event, notice caller SX calling subscriber off-hook to caller Softswitch (SX).Caller SX returns response according to the regulation of MGCP agreement to caller AG.
In call flow mentioned in this article, receive order Fang Jun and can return response message to sending order side according to the regulation of MGCP agreement.
Step 104: caller SX sends notification request message (RQNT) to caller AG, carries the strategy that collects the digits, and indication AG uses this strategy that collects the digits to collect the digits, and indicates caller AG to send dialing tone to the calling subscriber simultaneously.
Step 105～106: caller AG send dialing tone according to the indication of caller SX to the calling subscriber, and returns response message simultaneously after the notice request of receiving caller SX.
Step 107: the calling subscriber begins dialing after hearing dialing tone.
Step 108: caller AG receives the number that the calling subscriber transfers to, and detects the requirement whether number satisfies the strategy that collects the digits, if satisfy, then sends a notification message (NTFY) to caller SX, carries the number of receiving; If caller AG detects the requirement that the number of receiving does not satisfy the strategy that collects the digits, wait for that then the user continues dialing, up to satisfying the strategy that collects the digits.After satisfying the strategy that collects the digits, caller AG sends a notification message (NTFY) to caller SX, carries the number of receiving.
Step 109: after caller SX receives the number that caller AG transmits, return response message to caller AG earlier, judge that then whether the number that receives satisfies the requirement that continues, if satisfy, then begins to continue; Otherwise continue to issue the strategy that collects the digits, satisfy redirect request up to the number that receives.
In this process, caller SX may after receiving the number that satisfies the strategy that collects the digits, issue the strategy that collects the digits to caller AG once more according to business demand; Caller AG can continue to collect the digits according to the new strategy that collects the digits, and will satisfy the number that collects the digits and send caller SX to, till the number that receives satisfies business demand.
Step 110: caller SX notifies called SX to begin to continue.
Step 111～112: in execution in step 110, caller SX sends to caller AG and creates connection message (CRCX), the link between indication caller AG foundation and the calling subscriber.Caller AG carries out the operation of setting up link after receiving message, and returns response message for caller SX.
Step 113～116: called SX sends to called AG and to create connection message (CRCX), and indicate called AG to called subscriber's ring after receiving the message that notice that caller SX transmits begins to continue.Called AG send ring back tone to the called subscriber after receiving message, and returns response message to called SX.Called SX notifies caller SX called subscriber ring after receiving response message.In the call flow of this paper, all suppose the called free time.
Step 117～119: caller SX sends modification connection message (MDCX) to caller AG after learning called subscriber's ring, and prompting caller AG is put ring-back tone to the calling subscriber.Caller AG returns response message for caller SX after the calling subscriber send ring-back tone.
Step 120～123: when called AG after the called subscriber sends ring back tone, the called subscriber then at any time might off-hook.When called off-hook, called AG detects after called subscriber's off-hook, and called AG sends a notification message (NTFY) to called SX, notifies called SX called subscriber off-hook.Called SX notifies caller SX called subscriber off-hook after called AG returns response message.
Step 124～126: caller and called SX revise connection message (MDCX) to AG transmission separately respectively after learning called subscriber's off-hook, indication AG sets up Media Stream.AG then sets up Media Stream under the indication of SX separately, and after returning response message to SX, calling subscriber and called subscriber enter talking state.
Step 127～130: during end of conversation, calling subscriber's on-hook.Caller AG sends a notification message (NTFY) to caller SX after detecting calling subscriber's on-hook, carries onhook event, notice caller SX calling subscriber on-hook.Caller SX notifies called SX calling subscriber's on-hook after returning response message to caller AG.
Step 131: called SX is after learning calling subscriber's on-hook, then according to prior art flow processing called subscriber hooks on process.
Step 132～133: in called SX execution in step 131, caller SX sends deletion connection message (DLCX) to caller AG, indication caller AG remove with the calling subscriber between be connected.Caller AG returns response message for caller SX after receiving this message.
Step 134～135: caller SX discharges this time calling out of calling subscriber, and detailed process is: caller SX sends notification request message (RQNT) to caller AG, and indication caller AG monitors next off-hook event.Caller AG returns response message for caller SX after receiving message.
So far, call flow finishes.
Step 127 is by calling subscriber's on-hook to step 135 description, the process of terminated call flow process, and when called subscriber's on-hook terminated call flow process, calling subscriber's hooks on process is the same with the process that step 127 is described to step 135, is not described in detail in this.
IP-based network, for example the NGN network all can cause the not high problem of jointing-success-rate of calling owing to IP network is unstable often.
The call proceeding failure is also referred to as call loss, and from user's angle, the call loss in the handshaking procedure mainly is divided into two big classes: first kind call loss is for can't hear prompt tone or information for a long time; The second class call loss is a wrong connection.First kind call loss comprises: can't hear dialing tone, button during user's off-hook and can't hear speech that can't hear the other side after ring-back tone, ring-back tone stop and button after finishing and can't hear the information of charging as prompting etc. after finishing.The second class call loss comprises: the user is at button or tin prompt tone or hear busy tone in communication process suddenly, or the called free time, but be prompted Called Busy, or when correctly importing called number, but be routed to another user without reason, or the user finds situations such as abnormal call ticket.
Cause the factor of call loss to be mainly following 3 points, comprising: network packet loss rate, signaling message retransmission time interval and maximum retransmission and from the subscriber dialing to user, obtain prompt tone or the bar number of information required signaling in this each stage.
At present, prior art is mainly around time interval that network packet loss rate, signaling retransmit with retransmit the improvement that these factors of maximum times reduce call loss, but the signaling bar in reducing calling procedure is counted this respect and seldom considered.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that improves jointing-success-rate of calling, and this method can reduce the signaling bar number that uses in the calling procedure, to reduce call loss, improves jointing-success-rate.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of method that improves jointing-success-rate of calling, this method may further comprise the steps:
A, access device send dialing tone to the user after detecting user's off-hook, and adopt the strategy that collects the digits of self current storage to collect the digits;
B, Softswitch issue the strategy that collects the digits that this calling calling subscriber uses next time to access device when call release, access device stores the strategy of receiving that collects the digits.
In addition, this method further comprises: the default strategy that collects the digits is set; When the user called out first, the strategy that collects the digits of current storage described in the steps A was the default strategy that collects the digits.
Wherein, among the step B, when call release, Softswitch indication access device is monitored next off-hook event.
Wherein, further comprise between steps A and the step B: access device is passed to Softswitch with the number of receiving, Softswitch detects the number receive, when detecting the number of receiving and do not satisfy redirect request, again issue the strategy that collects the digits, satisfy the redirect request of self up to the number of receiving.
Wherein, further comprise between steps A and the step B: access device is passed to Softswitch with the number of receiving, Softswitch detects the number receive, when detecting the number of receiving and not satisfying redirect request, and call release, execution in step B afterwards.
Wherein, described access device is IAD or integrated access device or Ethernet Phone or voice gateways or voice call.
A kind of method that improves jointing-success-rate of calling provided by the present invention changes the mode that at every turn issues the strategy that collects the digits in setting up calling procedure in the call release process and to issue the strategy that collects the digits.Owing to need when setting up calling, not issue the strategy that collects the digits, therefore reduce and set up the signaling number that uses in the calling procedure; And the operation of carrying out in the call release process that issues the strategy that collects the digits is carried the strategy that collects the digits by Softswitch and is finished when the indication access device is removed link, therefore do not increase unnecessary signaling; And when removing link and issuing the strategy that collects the digits, also indicate access device to monitor next off-hook event, thereby reduced the bar number that uses signaling in the calling procedure once more.By the improvement of this mode, reduced the call loss of user in calling procedure, improved the success rate that continues, particularly in the relatively poor network environment of network quality, effect is particularly evident.

Embodiment
Core concept of the present invention is: issue the strategy that collects the digits in the call release process; In calling procedure next time, use the strategy that collects the digits that issues in the last call release process to collect the digits, finish calling procedure.
Detailed process is as shown in Figure 2: access device directly send dialing tone to the calling subscriber when detecting calling subscriber's off-hook, and collects the digits according to the strategy that collects the digits that last time, Softswitch issued during call release.When the number of receiving satisfies the redirect request of Softswitch, according to prior art continue and communication process continues and converses.After conversation is finished, in the call release process, issue the strategy that collects the digits that this calling subscriber uses in the calling procedure next time to access device by Softswitch, access device is stored this strategy that collects the digits, and waits for when this calling subscriber makes a call next time and using.
Now same is the NGN network of carrying with IP, and access device is AG, uses the MGCP agreement to be example in the call flow, and the inventive method is described in detail.Idiographic flow is as shown in Figure 3:
Step 301～302: calling subscriber's off-hook, caller AG directly send dialing tone to this calling subscriber after detecting calling subscriber's off-hook.Simultaneously, in the storage inside module of this caller AG, as the internal memory of caller AG or database, search and obtain this calling subscriber and discharged the strategy that collects the digits that issues in the communication process in last time, and use the strategy that collects the digits that finds to collect the digits.
If this calling subscriber uses the inventive method first, then the release communication process of this user last time carries out according to prior art, and caller SX does not issue the strategy that collects the digits that uses in this calling procedure to caller AG.Therefore, in this case, caller AG inside can set in advance and store the default strategy that collects the digits, and caller AG then uses the default strategy that collects the digits to collect the digits.
Step 303～327: continue and call operation according to art methods, step 107～131 implementation processes concrete and in the prior art calling procedure are identical, are not described in detail in this.
Step 328: caller SX discharges this conversation of calling subscriber after learning calling subscriber's on-hook.Detailed process is: caller SX sends DLCX message to caller AG, and indication caller AG removes and connects, and carries the strategy that collects the digits in this message, and indication caller AG monitors the notice of next off-hook event.Wherein, the strategy that collects the digits that carries in this message is used to refer to the strategy that collects the digits that this calling subscriber of caller AG uses in the calling procedure next time.
The message that the dismounting that sends to caller AG at caller SX connects, also can not carry and indicate caller AG to monitor the notice of next off-hook event, in this case, caller SX then sends notification request message (RQNT) to caller AG, and indication caller AG monitors next off-hook event.At this moment, caller AG returns response message for caller SX after receiving message.
Step 329: caller AG handles each information unit in this message after receiving the message that caller SX sends, and removes being connected between caller AG and the calling subscriber; Obtain the strategy that collects the digits in the message, and the policy store that will collect the digits is in the storage inside module of caller AG, as internal memory or the database of caller AG; Monitor next off-hook event.Then, return response message to caller SX.
So far, the call flow of the inventive method finishes.
When caller SX is discharging the strategy that collects the digits that issues to caller AG in the communication process, no longer be suitable for calling subscriber's calling procedure next time, that is to say needs to upgrade when collecting the digits strategy, can solve by following approach:
When using the strategy that collects the digits that issues in the call release process, caller AG collects the digits, and the number of receiving reported to after the caller SX, after just having carried out step 304 of the present invention, because satisfying the strategy that collects the digits of caller SX requirement changes, therefore, caller AG can not satisfy the redirect request of caller SX again to the number of caller SX report.In this case, caller SX will issue the new strategy that collects the digits and give caller AG, and caller AG will use the new strategy that collects the digits to collect the digits, and the number of receiving is reported to caller SX, and caller SX begins to continue receiving that number satisfies under the situation of redirect request.Caller SX continue, converse and discharge the conversation identical with step 306～329 among the present invention, be not described in detail in this.
The present invention can also solve the problem of the policy update that collects the digits by following approach:
When caller SX when receiving the number that step 304 caller AG report comes, judge that the number of receiving does not satisfy the requirement that continues, and then directly enters step 328 and removes this time calling out of calling subscriber, and in removing the process that connects, issue the strategy that collects the digits.The calling subscriber is after hearing busy tone, learn this time to call out and do not continue successfully, then on-hook, and can be after on-hook, off-hook is called out again once more, then can carry out call operation according to method as shown in Figure 3 this moment, and caller AG then can use the strategy that collects the digits that newly issues to collect the digits in calling procedure.
In embodiment of the present invention, what mentioned all is the operation of being initiated on-hook by the calling subscriber, and when by called subscriber's on-hook, the inventive method is suitable equally.
Described herein access device except that AG, can also be voice gateways, integrated access device; Also can be the terminal equipment with access function, as Ethernet Phone and voice terminal, these terminal equipments with access function be carried out the function of AG in the present embodiment when using method provided by the present invention.
At this, the present invention is an example with MGCP protocol interaction flow process mainly, introduces the method that improves jointing-success-rate of calling, and method provided by the present invention can also be applicable to the call flow of other type network, agreement, as H.248 waiting.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
