Description
Technical field
The present invention relates to the communications field, abnormality eliminating method and server in particularly a kind of call proceeding process.
Background technology
VoIP (Voice over Internet Protocol, IP phone) is exactly with the analoging sound signal digitlization in brief, on IP (Internet Protocol, Internet protocol) network, does real-time transmission with the pattern of data packet.Along with the professional successful Application of increasing VoIP; And the continuous fusion of communication network and IP network; The VoIP business is more and more universal, even wireless network also begins to support and deployment VoIP is professional, and; The professional agreement of using of VoIP is more and more tended to SIP (Session Initiation Protocol, Session initiation Protocol) and corresponding Extended Protocol thereof.
Professional for the VoIP under the wireless network; Because the characteristics of unsettled characteristics of wireless network and the easy power down of user terminal; Support the professional user terminal of VoIP possibly occur at any time that radio signal quality is serious to descend or situation such as power down suddenly, thus the unusual condition of the link chain rupture that causes eating dishes without rice or wine, and application layer protocol SIP can't find in time that these are unusual; If be in this time in the call proceeding process of VoIP, the VoIP business can receive following influence:
If caller and called all be the mobile subscriber of same office point; The situation that the called user terminal false ringing can occur; If promptly call subscriber terminal the unusual condition that wireless signal variation or power down etc. cause chain rupture just occurred after having sent Invite message (call request message); This call failure then; But because the SIP detection is unusual less than this; Called user terminal begins ring when sending 180 message, be exactly false ringing, can cause invalid replying if the called subscriber in time replys also;
If call subscriber terminal is that (being that office direction is called out) called out by the office of striding to the calling of called user terminal, not only can false ringing, the situation that mistake is chargeed also might appear; With with ISUP (ISDN User Part; ISDNYong Hubufen) signalling interworking is an example, and another user of other networks of Wireless VoIP customer call has sent Invite message behind server at call subscriber terminal; Called user terminal no longer need call subscriber terminal send any message just can ring and off-hook reply; And send ANM (Answer Message, response message) to server, reply back called network side and just begin call list and chargeed; If call subscriber terminal the unusual condition that wireless signal variation or power down etc. cause chain rupture occurred send ACK (Acknowledgement confirms) message to server before, then 100 message, 18x message and 200 (replying) the message call subscriber terminal of server transmission all might not received; This depends on that unusual time point takes place call subscriber terminal, if after receiving 200 message, take place unusual, this moment, ACK message was not also sent; According to the regulation of SIP, send the server of 200 message and also can 200 message regularly be retransmitted N time in this case, still can not receive ACK message after N time just can remove this calling; And in this process, if the called subscriber has answered, the situation of any prompt tone can appear conversing and not having; But according to user's custom, the called subscriber is on-hook immediately not necessarily, waits the called subscriber to recognize and this time calls out when on-hook has again taken place unusually; The called network side has produced charging bill; Short then several seconds, long then tens seconds, but the caller network side is owing to think and call out not success and can call list; If the calling and called network belongs to different operators like this, it is unusual clearing then can to occur.
Summary of the invention
In order to solve the problem of being chargeed by false ringing that causes unusually and mistake in the voip call handshaking procedure under the wireless network, the embodiment of the invention provides abnormality eliminating method and the server in a kind of call proceeding process.Said technical scheme is following:
On the one hand, the abnormality eliminating method in a kind of call proceeding process is provided, said method comprises:

Embodiment
For making the object of the invention, technical scheme and advantage clearer, embodiment of the present invention is done to describe in detail further below in conjunction with accompanying drawing.
Embodiment one
The embodiment of the invention provides the abnormality eliminating method in a kind of call proceeding process, and referring to Fig. 1, method flow comprises:
101: after the Invite message that receives the call subscriber terminal transmission, detect call subscriber terminal and whether take place unusually;
102: take place then to remove the calling of call subscriber terminal, and discharge the related resource of this calling unusually to called user terminal if detect call subscriber terminal.
The method that the embodiment of the invention provides; Whether take place unusually through in the call proceeding process, detecting call subscriber terminal; And the calling of call subscriber terminal to called user terminal takes place in time to remove when unusual detecting call subscriber terminal; Discharge the related resource of this calling, can reduce the expense of calling system, and can promote called subscriber's impression; Reduce unnecessary ring, and under striding the sight that office, cross operator call out, in time note abnormalities and dismantling call can prevent that the mistake in the call proceeding process from chargeing.
Embodiment two
The embodiment of the invention provides the abnormality eliminating method in a kind of call proceeding process, and this method can be used for the voip call handshaking procedure under wireless network and the IP network, and is applicable to several scenes such as office call and office direction calling.For the ease of explanation, it is that example describes that the embodiment of the invention is called out with the office direction under the wireless network, but is not limited to this.Referring to Fig. 2, method flow comprises:
201: server receives the Invite message that call subscriber terminal sends;
Particularly; Server in the embodiment of the invention is meant any server that service and return response can be provided to the Invite message that call subscriber terminal sends; The embodiment of the invention is not done concrete qualification to this, for example, can be acting server (Proxy Server) or sip server (SIP Server); Wherein, Sip server can be again that IMS (IP Multimedia Subsystem, IP Multimedia System), NGN (Next Generation Network, next generation network) or other can be accomplished the network element of server capability.
Further; Server will carry out the response of original call flow after receiving the Invite message of call subscriber terminal transmission, is specially to call subscriber terminal and sends Temporary Response message 100; Send IAM (Initial Address Message to called user terminal; And receive ACM (Address Complete Message, message is accomplished in the address) and the ANM that called user terminal sends initial address message).Do not influence original call flow embodiment of the invention of the present invention and be not described in detail for above-mentioned.
202: judge whether and need carry out abnormality detection, if desired, then carry out 203 call subscriber terminal, otherwise, to carry out according to original call flow, flow process finishes;
Wherein, the 202nd, optional step.Can take certain radio open bandwidth because whether the detection call subscriber terminal unusual process takes place; Therefore can carry out earlier whether need carrying out the judgement of abnormality detection to call subscriber terminal; Optionally those are carried out abnormality detection by the serious scene of the problem that causes unusually, therefore carrying out 202 can reduce overhead.
Judge whether can be to the concrete mode that call subscriber terminal carries out abnormality detection:
Judge whether the calling that call subscriber terminal is initiated is that office direction is called out, if the problem that specification exception possibly cause mistake to be chargeed then need be carried out abnormality detection to call subscriber terminal; And/or,
Judge whether call subscriber terminal is the calling of under wireless network, initiating; If; It is unusual to explain that call subscriber terminal takes place easily; Then need carry out abnormality detection to call subscriber terminal, wherein, domain name or number section that can be through call subscriber terminal or increase distinctive mark and whether distinguish call subscriber terminal at wireless network.
Preferably, can above-mentioned two deterministic processes all carry out, the promptly final office direction of only initiating under wireless network to call subscriber terminal is called out and is carried out abnormality detection, can reduce the overhead that abnormality detection is brought like this.
203: detect call subscriber terminal and whether take place unusually, if, then carry out 204, otherwise, carry out 206;
Particularly, whether the detection call subscriber terminal unusual concrete mode takes place can be: to call subscriber terminal transmission solicitation message, and pick up counting; If before timing reaches Preset Time, receive the detection response message that call subscriber terminal sends, then send new solicitation message, and pick up counting again to call subscriber terminal; If before timing reaches Preset Time, do not receive the detection response message that call subscriber terminal sends, then after timing reaches Preset Time, repeat to send the solicitation message of sending before to call subscriber terminal, and pick up counting again; Judge whether the number of times that repeats to send reaches preset maximum number of retransmissions, if it is unusual to judge that then call subscriber terminal takes place.Wherein, the call subscriber terminal generation possibly be the unusual condition that wireless signal variation or power down etc. cause chain rupture to have occurred unusually.
Further, referring to Fig. 3, for detecting call subscriber terminal whether unusual flow chart takes place.Need to prove that solicitation message among Fig. 3 and detection response message are uncertain with respect to the order of 18x message, 200 message and ACK message, are to change with the actual conditions of calling out; And not that every solicitation message all can have corresponding detection response message; Wherein, after the called user terminal ring, server can send 18x message to call subscriber terminal; After called user terminal is replied; Server can send 200 message to call subscriber terminal, and waits for that call subscriber terminal returns the ACK message to this 200 message, and 18x message is represented any a piece of news between 180 to 189.That is to say; Server can send many solicitation message and receive many and detect response message to call subscriber terminal before receiving ACK message; And after receiving ACK message, also might receive the detection response message; Only drawn among Fig. 3 for the first time and to have sent solicitation message and to receive the content of relevant detection response message, but be not limited to this to call subscriber terminal.Particularly, request message is surveyed in the concurrent censorship of server constructs, and picks up counting; If reach in timing and to receive the detection response message before the Preset Time, and also do not receive ACK message, then construct and send new solicitation message, and pick up counting again to 200 message; If before timing reaches Preset Time, do not receive the detection response message, then after timing reaches Preset Time, send once more and the identical solicitation message of solicitation message of sending before, and pick up counting again; If the number of times that repeats to send is not still received the detection response message after reaching preset maximum number of retransmissions, it is unusual to judge that then call subscriber terminal takes place.
Alternatively, in order to reduce the idle message load, server can be set in and after call subscriber terminal sends 200 message, initiate solicitation message first.
If the 18x message in Fig. 3 flow process requires reliability to transmit; Then corresponding flow process can become as shown in Figure 4; Receive the 18x message of server transmission at call subscriber terminal after; Send PRACK message notification server 18x message to server and received that server returns the response message 200 of PRACK message again to call subscriber terminal.Certainly, some other variation also possibly take place in the call proceeding flow process, but no matter how the call proceeding flow process changes, the transmission of solicitation message and etc. the mechanism of response message to be detected all similar with above-mentioned description to Fig. 3, the embodiment of the invention repeats no more.
Wherein, above-mentioned clocking capability can be accomplished by timer, and the embodiment of the invention is not done concrete qualification to this, for example can be Timer_c.The length of Preset Time can be configured according to the various network demand in advance, and suggestion is a unit with the millisecond.In addition, maximum number of retransmissions also can be pre-configured, for example is configured to N, and N is the integer more than or equal to 1.
204: take place then to remove the calling of call subscriber terminal, and discharge the related resource of this calling unusually to called user terminal if detect call subscriber terminal;
Particularly, this calling of call subscriber terminal and called user terminal is removed in the server dismounting that initiatively makes a call, and discharges the related resource of this calling, such as interface-free resources that takies or the like.
205: record is removed former because detecting call subscriber terminal takes place unusually, and flow process finishes;
Particularly, the dismounting reason of noting can check for operator, thereby can more specifically analyze the reason of call failure.
206: if receive the ACK message that call subscriber terminal sends, or, receive the call tear down message that call subscriber terminal or called user terminal send, then stop to detect.
Stop to detect and specifically to comprise: stop timing, and the follow-up detection response message that receives is done discard processing.
Particularly, receive,, all stop to detect timer at once, if follow-up receiving detected response message then done discard processing no matter whether also have the solicitation message wait-for-response to after the ACK message of 200 message; If initiated call tear down receiving, then stop to detect timer at once, if follow-up receiving detected response message then done discard processing to call subscriber terminal before the ACK message of 200 message or called user terminal.
Need to prove; Preferably; Solicitation message in the embodiment of the invention can be the OPTIONS message that defines in the RFC3261 agreement; Detecting response message is and OPTIONS message corresponding response message, wherein, judges through the Transaction ID (transaction number) in OPTIONS message and the response message whether the response message that call subscriber terminal returns is the response to OPTIONS message.OPTIONS message is the message that is used for inquiring user terminal or server-capabilities that defines in the RFC3261 agreement, and all user terminals and server are all supported OPTIONS message.OPTIONS message can be sent in dialogue, also can outside dialogue, send, and not influence original call state.Stipulate in the RFC3261 agreement,, can think that corresponding user terminal is unreachable if OPTIONS message is not received response.The principle of server constructs OPTIONS message and mode can not comprise the Accept header field with 11.1 trifles of RFC3261 agreement, so that reduce the size of response message.After call subscriber terminal is received OPTIONS message, respond by RFC3261 agreement predetermined process mode.Use OPTIONS message and corresponding response message thereof to be as solicitation message and the benefit that detects response message; Utilize existing RFC3261 agreement; Employed message and flow process just can realize based on the RFC3261 agreement; Need not increase message and Singapore dollar newly, and all user terminals are supported all; Make method for detecting abnormality simple, be beneficial to realization, only need server side according to the method described above step make amendment and get final product.
Alternatively, solicitation message with detect response message and also can use self-defining message, perhaps can also use other sip messages, just for example use in the PING in draft stage message etc.Use these message except server side need be revised, the method for above-mentioned abnormality detection also need revised and then support to subscriber terminal side.
The method that the embodiment of the invention provides; Through in the call proceeding process, sending solicitation message to call subscriber terminal; And receive detection response message that call subscriber terminal returns and detect call subscriber terminal and whether take place unusually; Can in time detect the unusual of call subscriber terminal, and in time remove the calling of call subscriber terminal when unusual detecting, discharge the related resource of this calling to called user terminal; Can reduce the expense of calling system; And can promote called subscriber's impression, reduce unnecessary ring, and under striding the sight that office, cross operator call out, in time note abnormalities and dismantling call can prevent that the mistake in the call proceeding process from chargeing; In addition, record is removed former because detect the call subscriber terminal generation unusually behind the dismantling call, can make operator can more specifically analyze the reason of call failure.
