Embodiment 1

[0036] Embodiment 1: In the address message signal addr1 of the existing protocol, the information indicating that "the calling number is not available" is added. The original H.248.29 protocol describes the calling number parameter si contained in the signal addr1 message as follows:

[0037] A.1.2.1.2.3 Source Number

[0038] Parameter Name (parameter name): Source Number (calling number)

[0039] ParameterID (parameter ID): si (0x0003)

[0040] Description: The calling party number digit string, that iscolleded during compelled register signaling.

[0041] Type (type): String (string)

[0042] Optional (optional): Yes (optional)

[0043] Possible Values ​​(possible values): A sequence of the characters'0'through'9'. (A sequence of characters between 0 and 9)

[0044] Default (default value): None (none)

[0045]From the description of the calling number parameter above, the information that the calling number is not available can be expressed by setting a special si (c...

Embodiment 2

[0063] Embodiment 2: The above situation of incoming calls is based on the current protocol restrictions. The configuration of "no request for calling number" or "request for calling number" and "request for calling number location" is configured on the MG. In fact, this control and The business is closely related. When the business processing needs to be configured not to request the calling number, the MGC will dismantle or not dismantle the line. There will be different default number provision methods when the line is not dismantled. This configuration is placed on the MG. The MGC cannot make a judgment in time.

[0064] The following is the solution to put this configuration on the MGC:

[0065] Expand the existing H.248 protocol package on R2, configure the calling number request on the MGC, and the MGC configures the calling number request of the MGC through the bcas / sza (occupancy confirmation / number receiving indication) event ("do not request calling number" or "req...

Abstract

A method for transmitting unobtained information of calling number under soft switch framework includes interacting message carried with unobtained information of calling number between media gateway and media gateway controller when calling number can not be obtained, carrying out treatment on call by media gateway or media gateway controller according to unobtained information of calling number.

Description

technical field [0001] The present invention relates to the technical field of soft switching, and specifically relates to the technology of message interaction between media gateways and media gateway controllers. Background technique [0002] Relay signaling is a signaling system used to control call connection between switches. It is divided into two categories: common channel signaling and channel associated signaling. The Telecommunication Standardization Sector (International Telecommunication Union-Telecommunications Standards Department) specification is called R2 signaling, and the Chinese standard road-associated signaling is called China No. 1 signaling, and China No. 1 belongs to a subset of R2. [0003] Softswitch is a new generation of core network switch that separates bearer and control. It is divided into two types of network elements: media gateway (MG Media Gateway) and media gateway controller (MGC Media Gateway Controller) according to functions. The bas...
