CN103957135A - Method for no-break conversation in IP address switching process - Google Patents

Abstract

The invention discloses a method for no-break conversation in an IP address switching process. The method comprises the following steps that communication terminals execute network monitoring operation; after a conversation is established between the communication terminals, a voice packet is cached by the communication terminals and a server; when the IP address switching of one communication terminal is monitored, the server is informed of the IP address updating information of the communication terminal; the server automatically informs the other communication terminal of the IP address updating of the communication terminal A; the conversation is reestablished, and the voice package cached after the break-off of the conversation is sent out by the communication terminals and the server. According to the method for the no-break conversation in the IP address switching process, after the IP addresses of the communication terminals are changed, users can continue the previous conversation content through quite transient recovery, and the no-break conversation of the users in the IP address switching process is achieved.

Description

A kind of in IP address switchover process the method for dropped calls not

Technical field

The present invention relates to a kind of in IP address switchover process the method for dropped calls not, belong to communication technical field.

Background technology

, often there is network and break down and need to be switched to the situation of backup network in constantly universal along with network application.Or, when WiFi and 3G/GPRS switch mutually, also face the problem that the IP address of communication terminal need to be switched.If now communication terminal A and communication terminal B converse, because communication terminal A has changed IP address midway or again got new IP address, communication terminal A and communication terminal B can interrupt current talking.And communication terminal A with new IP address to server re-register, again dialing after, between communication terminal, just can converse.

Although prior art can realize while changing in IP address again to server registration, still has following problem:

1) when certain equipment is no longer when IP address in its original place network is associated, its active session can be forced to interrupt.

2) from dropped calls, to user, notice intercourse, the voice packet of user and the other side's call is easily lost; When call recovery, some contents that user has missed the other side and sent out;

3) after dropped calls, communication terminal needs again to server, to register, and then manual dialup is to the other side, and call is just recovered.For the user of communication terminal, re-register and this process time of dialing is longer again, it is poor that user experiences.

Comprehensive above-mentioned known, how to make realizing user's communication when IP address switchover and do not interrupt, improve user's call and experience, be one of major issue of facing of current communication technical field.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

The method of dropped calls not in IP address switchover process provided by the present invention, comprises following step: the network monitoring module of communication terminal is carried out network monitoring operation; Set up after call each communication terminal and server buffer voice packet; When network monitoring module listens to the IP address switchover of communication terminal, announcement server upgrades the IP address of communication terminal automatically; The IP address of server update communication terminal, and notify other communication terminals to upgrade the IP address of communication terminal; Other communication terminals upgrade complete, and call re-establishes, and each communication terminal and server continue the voice packet of buffer memory after dropped calls to send.Below specific embodiment of the invention step is elaborated.

Step 1, the network monitoring module of communication terminal is carried out network monitoring operation.

Communication terminal is registered to server, and announcement server is preserved its relevant information, as IP address, user name, password etc.In communication terminal, configuration network is monitored module, and when communication terminal starts, network monitoring module, to the operating system registered network listening broadcast of communication terminal, starts to carry out network state snoop-operations.If while having network change, the network state change operation in network monitoring module is adjusted back and carried out to the operating system of communication terminal.

Step 2, sets up after call each communication terminal and server buffer voice packet.

Call between communication terminal can be individual calling, group calling or broadcast etc.In the present invention, with the communication process between two communication terminals, describe.

Fig. 1 is the schematic diagram of normal talking between communication terminal in the present invention.The process that communication terminal A and communication terminal B set up call adopts Session Initiation Protocol, be not elaborated here.In the present invention, in order to prevent because dropped calls causes voice package losing, once set up when the call of communication terminal A and communication terminal B, communication terminal A, communication terminal B and server start voice packet to carry out buffer memory.For the cache-time of voice packet, communication terminal and server can be set accordingly.

Step 3, while listening to the IP address switchover of communication terminal, announcement server upgrades the IP address information of communication terminal automatically.

After the IP address that network monitoring module listens to communication terminal changes, the disconnection that the call between communication terminal in fact can be very of short duration, then by communication terminal from trend server notification IP address lastest imformation, then recover rapidly call.Referring to Fig. 2, when listening to the network state of communication terminal A, change while causing IP address switchover, communication terminal A is by the IP address switchover message of definition, and announcement server this communication terminal IP address changes, and need to upgrade current IP address.The process that process by announcement server in the present invention is upgraded communication terminal IP address is very of short duration, so the temporary transient disconnection of call meeting between communication terminal.And communication terminal re-starts while registering, need the state of server replacement communication terminal, comprise information such as re-registering IP address, username and password.The process re-registering is more loaded down with trivial details.And communication terminal announcement server carries out IP address switchover, the IP address that only needs to upgrade communication terminal is just passable.

Step 4, the IP address of server update communication terminal, and notify other communication terminals to upgrade the IP address of this communication terminal;

Server receives the notice of communication terminal A, can upgrade the IP address of communication terminal A.The IP address renewal for the treatment of communication terminal A is complete, the communication terminal that notice is communicated by letter with communication terminal A automatically, and the IP address of communication terminal A changes.Server sends to other communication terminals by the IP address of renewal, and other communication terminals receive corresponding message, and the IP address of communication terminal A communication is upgraded.In the present invention, to upgrade this process very of short duration for IP, and user is almost imperceptible, only once can recover call to two message communications.

Step 5, call re-establishes, and communication terminal and server continue the voice packet of buffer memory after dropped calls to send.

Call between communication terminal is through very of short duration interruption, and the communication terminal that only needs IP address modification sends IP address modification message to server, and communication terminal in other calls does not need again to dial and sets up call.In prior art, call is set up in dialing again needs manual intervention, and user's experience is bad.Referring to Fig. 3, the IP address for the treatment of communication terminal upgrade complete after, communication terminal A, communication terminal B and server send the voice packet of buffer memory after IP address switchover respectively.

In sum, in IP address switchover process provided by the present invention, the method for dropped calls is not applied to communication terminal and server, can realize communication terminal IP address modification, and unbroken effect that makes to converse.In the present invention, after communication terminal IP address switchover, converse and do not interrupt, user does not need perception IP to switch and causes this process of dropped calls, has effectively improved user's experience; Voice packet before IP address switchover is carried out to buffer memory simultaneously, by very of short duration interruption, can automatically recover call, and the dialog context of user before continuing, each important moment do not missed; While carrying out group calling or broadcast for communication terminal, if there is the IP address of network, change, also can automatically recover communication.

Above to provided by the present invention in IP address switchover process not the method for dropped calls have been described in detail.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention, it being done, all will form infringement of patent right of the present invention, will bear corresponding legal liabilities.
