Embodiment 1
[0048] In this first embodiment, the PUSH function that comes with the system can be used to ensure that the IP phone client as the called user terminal is offline or not activated, and can also receive an incoming call request (that is, a call initiated by the calling user terminal) request), that is, to implement an IP call request through a PUSH message. Specifically, such as figure 2 As shown, the corresponding processing may include:
[0049] Step 21, the calling party (that is, the calling user terminal based on the Internet Protocol) logs into the IP telephony server, and the server sets the calling party ID status as online, so that it can query whether it is online when it is the called user terminal.
[0050] Step 22, the calling party initiates a call request to the called party (that is, the called user terminal based on the Internet protocol), and the corresponding call request message will be sent to the server.
[0051] Step 23: After receiving the call reque...
Embodiment 2
[0057] In the second embodiment, the short message gateway can be used to ensure that the IP phone client as the called user terminal is offline or not activated, and can also receive the call request initiated by the calling user terminal. Specifically, such as image 3 As shown, the corresponding processing may include:
[0058] Step 31, the calling party logs into the IP phone server, and the server sets the ID status of the calling party as online.
[0059] Step 32, the calling party initiates a call request to the called party, and a corresponding call request message is sent to the server.
[0060] Step 33, the server receives the call request, finds out that the called party is not online according to the ID of the called party in the call request, and then forwards the call request to the short message gateway (or short message gateway).
[0061] Step 34: After receiving the call request, the short message gateway directly packs the call request into a short message ...

Abstract
The invention discloses a method, device and system for internet protocol telephone off-line calling. The method includes the steps that a call request based on a calling party terminal of the internet protocol is received and includes address information of the calling party terminal; when a called party terminal based on the internet protocol is judged to be not on line, the calling request is sent to a third party gateway; the third party gateway sends the calling request to the called party terminal based on the internet protocol; after the called party terminal based on the internet protocol receives the calling request sent by the third party gateway, calling connection between the called party terminal and the calling party terminal based on the internet protocol is established according the address information, included in the calling request, of the calling party terminal based on the internet protocol. According to the technical scheme, the called party terminal based on the internet protocol can still receive the calling request initiated by the calling party terminal based on the internet protocol under the condition that the called party terminal based on the internet protocol is in an off-line state, and the calling connection can be rapidly established after the calling request is received, so that communication between a calling party and a called party is achieved without logging in a server again.
Description
technical field [0001] The present invention relates to network communication technology, in particular to a method, device and system for offline calling. Background technique [0002] IP (Internet Protocol, Internet Protocol) telephone is attracting attention as the "next generation telephone". Compared with the traditional voice phone, the IP phone communicates through the IP network, so it can provide more powerful functions, lower operating costs and higher call quality. [0003] Specifically, the IP phone needs to realize the corresponding call through the corresponding IP phone client, that is, the IP phone client needs to log in to the designated server, and establish a connection with the designated server, so as to facilitate the call signaling between the IP phone clients. Based on the established connection is relayed through the server. For example, when the calling party calls, it will send the corresponding call request to the server. After receiving the cal...
