Embodiment 1

[0037] Embodiment 1: The MG on the outgoing side actively asks the MGC for calling information

[0038] Such as figure 2 As shown, when the outgoing side PSTN (Public Switched Telephone Network) asks the outgoing side MG for calling information, but when the MG does not have this information, the MG asks the MGC for the calling information event from the MG defined in the present invention (such as the extended bcas attribute casa=1) to request the caller information from the MGC to complete the call, including the following steps:

[0039] Step 101, the MG at the originating side under the control of the MGC reports the called number to the MGC;

[0040] Step 102, the MGC issues the called number to the MG at the origin side;

[0041] Step 103, the MG at the outgoing side sends the called number to the lower-level office (ie, the PSTN at the outgoing side) through channel-associated signaling;

[0042] Step 104, after receiving the called number, the lower office requests t...

Embodiment 2

[0067] Embodiment 2, the MG on the incoming side is controlled by the MGC device to process the caller information (whether the attribute rqsi of the calling number is required, and this flag is configured on the MGC)

[0068] Such as image 3 As shown, when the MG requests the calling number from the PSTN side after timeout, it sends a non-mutual control signal A3 to the PSTN to request KD (the non-mutual control signal is sent because the MG’s mutual control signal requesting the calling number has not yet been received. When the response is reached, that is, the mutual control process is not over yet, at this time, the MG cannot send another mutual control signal, the same below), after receiving the KD, the MG sends the called number and the KD to the MGC to complete the connection, if the KD times out Report a timeout error to the MGC, including the following steps:

[0069] Step 304, the MG at the incoming side asks for the calling number from the upper-level office;

...

Embodiment 3

[0076] Embodiment 3, the incoming MG is controlled by the MGC device to process the calling information (whether the attribute rqsi of the calling number is required, this flag is configured on the MGC)

[0077] Such as Figure 4 As shown, when the MG requests the calling number from the PSTN side for a timeout, it directly reports a timeout error to the MGC, and the MGC releases the call this time.

[0078] Step 404, the MG at the incoming side requests the calling number from the upper-level office,

[0079] Step 405, the MG fails to obtain the calling number after timeout;

[0080] Step 406, the MG at the incoming side reports an error to the MGC

[0081] In the above step 405, if the MG can obtain the calling number, then its subsequent steps are the same as steps 306-308 in the second embodiment. The incoming side MG sends a mutual control signal A3 to the front-level office to request KD, and after obtaining the calling number and KD Report to the MGC, and report an e...

Abstract

A method for a media gateway obtaining calling information is provided, the media gateway and a media gateway controller make the media gateway obtain the calling information through the intercommunicating information. The method includes: defining the event that the media gateway requests the media gateway controller for the calling information, a lower level device requesting the media gateway in the outgoing side for the calling information, the media gateway in the outgoing side originating the event for requesting the calling information to the media gateway controller, the media gateway controller responding to the event for requestingthe calling information. Also an property of whether to need the calling number or not is provided, the media gateway controller sends the property of whether to need the calling number or not to the incoming side media gateway, the incoming side media gateway determines whether to request the forward device for the calling number.

Description

technical field [0001] The present invention relates to the processing of channel-associated signaling, in particular to a method for realizing the acquisition of caller information by media gateways under the framework of NGN (next generation network). Background technique [0002] The signal mode of channel-associated signaling refers to a signal mode in which the signals of each voice channel are transmitted through the voice channel itself or through the signal channel corresponding to the voice channel. According to its signal content, it is divided into line signal and register signal, and sometimes DC pulse signaling is required. [0003] In NGN (Next Generation Network) architecture, channel-associated signaling is sent and received by MG (Media Gateway) equipment under the control of MGC (Media Gateway Controller) through the H248 protocol. [0004] At present, the processing of road-associated signaling (R2 or China No. 1 road-associated signaling) has the followi...
