Embodiment 1

[0026] The embodiment of the present invention provides a method for handling exceptions in the call connection process, see figure 1 , the method flow includes:

[0027] 101: After receiving the Invite message sent by the calling user terminal, detecting whether the calling user terminal is abnormal;

[0028] 102: If it is detected that the calling user terminal is abnormal, disconnect the call from the calling user terminal to the called user terminal, and release related resources of the call.

[0029] The method provided by the embodiment of the present invention detects whether the calling user terminal is abnormal during the call connection process, and disconnects the call from the calling user terminal to the called user terminal in time when the abnormality of the calling user terminal is detected, and releases the call. Call-related resources can reduce the overhead of the call system, improve the experience of the called user, reduce unnecessary ringing, and detect...

Embodiment 2

[0031] The embodiment of the present invention provides a method for handling exceptions in the call connection process. The method can be used in the VoIP call connection process under the wireless network and the IP network, and is applicable to various scenarios such as intra-office calls and office-to-office calls. For ease of description, the embodiment of the present invention uses an office call under a wireless network as an example for description, but is not limited thereto. see figure 2 , the method flow includes:

[0032] 201: The server receives the Invite message sent by the calling user terminal;

[0033] Specifically, the server in the embodiment of the present invention refers to any server that can provide services to the Invite message sent by the calling user terminal and send back a response, which is not specifically limited in the embodiment of the present invention, for example, it may be a proxy server (ProxyServer) Or a SIP server (SIPServer), wher...

Embodiment 3

[0058] The embodiment of the present invention provides a server, which refers to any server that can provide services to the Invite message sent by the calling user terminal and send back a response, and can execute the method steps in the second embodiment. Not specifically limited, for example, it may be a proxy server (ProxyServer) or a SIP server (SIPServer), wherein the SIP server may be IMS, NGN or other network elements capable of performing server functions. see Figure 5 , the server includes:

Abstract

The embodiment of the invention provides an exception handling method and a server in a calling continuous process, relating to the communication field. The method comprises the steps of detecting whether a calling user terminal generates an exception after receiving a calling request message sent by the calling user terminal; if the calling user terminal is detected to generate the exception, disassembling the calling from the calling user terminal to a called user terminal, and releasing the related resource of the calling. In the invention, by detecting whether the calling user terminal generates the exception in the calling handling process, and disassembling the calling from the calling user terminal to the called user terminal when the calling user terminal is detected to generate the exception, and releasing the related resource of the calling, the cost of a calling system can be reduced, and the feeling of a called user can be improved, the unnecessary calling can be reduced, and the mistakenly billing in the calling handling process can be prevented by finding the exception and disassembling the calling in time under a cross local network and cross operator calling situation.

Description

technical field [0001] The invention relates to the communication field, in particular to an exception handling method and a server in the call connection process. Background technique [0002] VoIP (VoiceoverInternetProtocol, Internet Protocol Telephone) in short is to digitize the analog voice signal and transmit it in real time on the IP (InternetProtocol, Internet Protocol) network in the form of data packets. With the successful application of more and more VoIP services and the continuous integration of telecommunication networks and IP networks, VoIP services are becoming more and more popular, and even wireless networks are beginning to support and deploy VoIP services, and the protocols used by VoIP services are becoming more and more popular. The more inclined to use SIP (SessionInitiationProtocol, Session Initiation Protocol) and its corresponding extension protocol. [0003] For the VoIP service under the wireless network, due to the unstable characteristics of ...
