Embodiment 1

[0042] Such as figure 2 As shown in FIG. 1 , it is a schematic flow chart of a billing method in Embodiment 1. The method includes:

[0043] Step 101: After the call between the calling and called IMS terminals is established, the calling SBC receives the call establishment message sent by the AS and includes the calling IMS terminal ID, and the called SBC receives the call setup message including the called IMS terminal ID sent by the AS information.

[0044] In this step 101, the calling IMS terminal registers and logs in the IMS network through the calling SBC in the IMS network, and initiates a call request to the called IMS terminal. When the call service between the calling IMS terminal and the called IMS terminal is successfully established, the upper-layer AS of the IMS network starts to charge the call, and simultaneously sends the call establishment message containing the calling IMS terminal identifier to the calling SBC ( That is, the SBC registered by the calli...

Embodiment 2

[0066] Embodiment 2 of the present invention describes the solution of Embodiment 1 of the present invention in detail through specific examples, assuming that the solution of Embodiment 2 takes the calling SBC notifying the AS to release the need to stop charging as an example for illustration.

[0067] Such as image 3 As shown, it is a schematic flow chart of a billing method in Embodiment 2, and the specific steps include the following:

[0068] Step 201: The calling IMS terminal A registers and logs in to the IMS network through the calling SBC.

[0069] Step 202: The calling IMS terminal A establishes a traditional Expire keep-alive mechanism with the calling SBC, and actively sends a keep-alive command to the calling SBC within the specified range of Expire.

[0070] In this step 202, the keep-alive mechanism of the calling IMS terminal A is static keep-alive.

[0071] Step 203: The calling SBC determines the registration status of the calling IMS terminal. If the reg...

Embodiment 3

[0093] Such as Figure 4 As shown, it is a schematic structural diagram of a session border controller SBC in the third embodiment, and the SBC includes: a receiving module 41 , a judging module 42 and a sending module 43 . in:

[0094] The receiving module 41 is used to receive the call setup message sent by the AS after the call between the calling and called IMS terminals is established, and includes the IMS terminal identifier; the judging module 42 is used to judge the corresponding IMS terminal identifier according to the receiving module 41. Whether the media data flow of the IMS terminal of the IMS terminal is abnormal, if so, then judge the current registration state of the IMS terminal according to the keep-alive mechanism negotiated with the IMS terminal; In the login state, instruct the AS to stop charging this call.

[0095] Specifically, the receiving module 41 is specifically configured to receive the call setup message sent by the AS through the S_CSCF.

Abstract

The invention discloses a billing method, a device and a system. The billing method mainly comprises the following steps: after calling between main called internet protocol multimedia subsystem (IMS) terminals is established, a main calling SBC and a called SBC receives calling establishing information containing main called IMS terminal identification sent by AS, so that the main calling SBC and the called SBC respectively monitor exceptions of media data flow transmitted by the corresponding IMS terminals according to the respective received IMS terminal identification, and judging current login state of the IMS terminals according to a keep-alive mechanism coordinated with the IMS terminals; when the IMS terminal current login state is in a un-login state, AS is timely informed to stop calling billing between the IMS terminals, thereby improving calling billing accuracy of AS between the IMS terminals.

Description

technical field [0001] The solution of the present invention relates to the field of IMS (IP Multimedia Subsystem, IP Multimedia System), in particular to a charging method, device and system for IMS calls. Background technique [0002] With the continuous development of the IMS network, more and more IMS terminals (for example: SIP (SessionInitiation Protocol, application layer signaling control protocol) telephones, IAD (Integration Access Device, integrated access device) connected POTS ( Plain Old Telephone Service, plain old telephone service) telephone or PC (Personal Computer, personal computer) soft terminal, etc.), the IMS terminal registers in the SBC (Session Border Controller, Session Border Controller) of the IMS network, and then logs in to the IMS network After that, the SBC needs to keep alive the registration status of the IMS terminal and track the registration status of the IMS terminal. [0003] After the IMS terminal successfully logs in to the IMS netw...
